However few studies especially in Africa have evaluated the association between HBsAg serum level and liver fibrosis severity. The objective of this study was to estimate the correlation between HBsAg serum level and liver fibrosis severity with treatment naive chronic hepatitis B patients in Cote d’Ivoire. Methodology: It is a prospective study covering from February 1st, 2014 to April 30st, 2015 at Centre Hospitalier et Universitaire de Yopougon and a private medical office in Abidjan, Cote d’Ivoire. Inclusion criteria for patients were: HBsAg positive, known HBeAg status, serum HBsAg levels, serum HBV DNA levels, complex serum markers and absence of HCV, HDV, or HIV co-infection, drinking more than 30 g/day for men and 20 g/day in women over 10 years, metabolic disease and/or hepatic overload. Pearson’s Chi-square test (r2), Anova, Spearman, T-Student, Pearson’s (r) correlations and Mann Withney’s Test were carried out as appropriate. A p value < 0.05 was taken as significant. Results: We recruited, 105 patients (77 men) of whom the medium age was 39.01 ± 9.72 years. Predominant hepatitis B viral genotype was E (93%). Less than 10% patients had an inactive HBV in HBeAg-negative. Patients had an average high HBsAg serum level (mean 12111.2 ± 10617.4 IU/ml) as well as the one viral load (mean 4.4 e7 ± 7.5 e7). Serum ALAT levels averaged at the upper limit of normal value. The average liver fibrosis score was 0.34 ± 0.22 and the degree of viral activity was 0.19 ± 0.20. Half of our patients had no fibrosis (35.24%) or had mild fibrosis (20.95%). No significant association was observed between HBsAg serum level and patient age (p = 0.3994), genre (p = 0.8075) or serum ALT levels (p = 0, 0787). In multivariate analysis, there’s a significant correlation (r = 0.239, p = 0.014) between HBV DNA levels and HBsAg serum level. There’s a significant correlation (r = 0.923, p < 0.0001) between HBsAg serum level and the dosage of alpha-fetoprotein. HBsAg serum level was not associated with the fibrosis stage (p = 0.281). HBsAg levels average with patients without fibrosis or carry a slight fibrosis (F0, F1) was higher than patients with moderate to severe fibrosis (F2, F3, F4): 13679.2 UI/ml ± 1956.48 versus 10610.52 UI/ml ± 8998.99 (p = 0.29). There’s a negative correlation between HBsAg level and the liver fibrosis score was negative (r = -0.069, p = 0.48). No significant association between HBsAg level and the liver fibrosis patients that were normal (p = 0.7965) or elevated (p = 0.5845). HBV DNA level was significantly associated with fibrosis score (r = 0.30, p = 0.0018). Conclusion: This study shows that there’s a negative correlation between HBsAg serum level and liver fibrosis severity treatment naive with African chronic hepatitis B viral HBeAg-negative patients.展开更多

Results The levels of serum total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C) and apolipoprotein(Apo) AI were lower in Bai Ku Yao than in Han(P【0.01 for all).The frequency of A and G alleles was 98.00%and 2.00%in Bai Ku Yao,and 95.20%and 4.80%in Han(P【0.01);respectively. The frequency of AA,AG and GG genotypes was 95.99%,4.01%and 0%in Bai Ku Yao,and 91.02%, 8.36%and 0.62%in Han(P【0.01);respectively.There were also significant differences in the genotypic and allelic frequencies between n and the ratio of ApoAI to ApoB in Han Chinese but not in Bai Ku Yao were different between the AA and AG/GG genotypes(P【0.05 for all).The G allele carriers had higher serum HDL-C and higher ApoAI to ApoB ratio than the G allele noncarriers.When serum lipid parameters in Han were analyzed according to sex,the G allele carriers had higher serum HDL and ApoAI levels in males (P【0.05),and lower ApoB level and higher ApoAI to ApoB ratio in females(P【0.05 for all).Multiple linear regression analysis showed that serum HDL-C levels were correlated with genotypes in both ethnic groups(P【0.05 each).Serum lipid parameters were also correlated with sex,age,body massindex,alcohol consumption,cigarette smoking,and blood pressure in both ethnic groups(P【0.05-0.001).Conclusions These results suggest that the PCSK9 E670G polymorphism is mainly associated with some serum lipid parameters in the Han population,both gender show different relations to different serum lipid parameters.The G allele carriers might have higher serum lipid profiles than the G allele noncarriers. ormal LDL-C(≤3.20 mmol/L) and high LDL-C subgroups (】 3.20 mmol/L,P【0.01;respectively) in Bai Ku Yao, and between normal ApoB(≤1.14 g/L) and high ApoB subgroups(】 1.14 g/L,P 【 0.01;respectively) in Han.展开更多

In this study the effects of consumption of raw garlic on serum lipid level, blood sugar and a number of effective hormones on lipid and sugar metabolism (thyroid hormones and insulin) in individuals either with high level of blood sugar or lipid were investigated. Eighty five volunteers having following clinical history enrolled in the study: Group 1: having blood sugar more than 126 mg/dl (30 vo-lunteers);Group 2: having cholesterol higher than 245 mg/dl (30 volunteers);Group 3: having blood sugar over 126 mg/dl and cholesterol more than 245 mg/dl (25 volunteers). In group 1, there wasn’t a sig-nificant differences between biochemical factors be-fore and after garlic consumption, whereas, in the second group after 6 weeks of garlic consumption a decline in cholesterol (P < 0.001), FBS and TG (P < 0.01) was observed but HDL-C (P < 0.001) was in-creased. Six weeks after termination of garlic con-sumption, cholesterol (P < 0.001), FBS and TG (P < 0.05) were in- creased and HDL-C (P < 0.01) was de-creased. In the third group, total cholesterol (P < 0.001), FBS (P < 0.01) and HbA1c decreased while HDL-C was in- creased. Other factors, including thy-roid hormones (T3, T4), TSH and insulin showed no significant alte- ration. In conclusion our results shown that raw garlic consumption can reduce the FBS and Lipid in hyperglycemic and/or hyperlipidemic individuals.展开更多

This study aimed to investigate the relation between serum phosphorus levels and risk of all-cause mortality in Chinese patients with ST-segment elevation myocardial infarction (STEMI) who had preserved renal function at baseline. Methods We enrolled patients with STEMI who had preserved renal function at baseline in Xuanwu Hospital from January 2011 to December 2016. Those patients were divided into four groups based on serum phosphorus levels. All-cause mortality rates were compared between groups. Mean duration of follow up was 54.6 months. We used Cox proportional-hazards models to examine the relation between serum phosphorus levels and all-cause mortality after adjustment for potential confounders. Results 1989 patients were involved and 211 patients (10.6%) died during follow-up. Based on serum phosphorus levels, patients were categorized into the following groups:< 2.50 mg/dL (n = 89), 2.51–3.50 mg/dL (n = 1066), 3.51–4.50 mg/dL (n = 672) and > 4.50 mg/dL (n = 162), respectively. The lowest mortality occurred in patients with serum phosphorus levels between 2.51–3.50 mg/dL, with a multivariable-adjusted hazard ratio of 1.19 (95% CI: 0.64–1.54), 1.37 (95% CI: 1.22–1.74), and 1.46 (95% CI: 1.35–1.83) in patients with serum phosphorus levels of < 2.50 mg/dL, 3.51–4.50 mg/dL and > 4.50 mg/dL, respectively. Conclusions Elevated serum phosphorus levels were associated with all-cause mortality in Chinese patients with STEMI who had preserved renal function at baseline.展开更多

Radioimmunoassay was used to examine the serum ferritin level (SFL) in 52 patients with RAU and in 54 controls. Both were divided into 2 groups in accordance with sex. The 36 female patients were subdivided into 3 age-groups as follows: 8 aged 22-24, 10 aged 25-34, and 18 aged 35-50 while the male patients were gathered as one single group aged 26-57. The subdivision was adapted similarly for the normal age-grouts. Although no significant difference in SFL was found between the male control and the male patient groups, differences between the female control and female patient groups showed highly significant which levels, with the ascendance of age, were P【0.001, P【0.005 and P【0.001, respectively. Also the difference between male and female control groups were significant (P【0.05). However, no significant differences in SFL were discovered among the 3 patient groups. 10 female patients with SFL【12ng/ml were tested with ferrous sulfate for one month, then their SFL was reexamined one week after the treatment. A highly significant difference in SFL was noted between the pre-ad post-treatment (P【0.001). 9 of them showed that the interval of recurrences were prolonged, the number of ulcers reduced, the pain less intensive and its duration shorter than those before the treatment. This study demonstrated that a singificant decrease in iron-storage occurred in female RAU patients. The authors concluded that the decrease SFL was possibly related to menstruation and child bearing.展开更多

Aim: Comparison of serum cholesterol values of obese with normal subjects and comparison of BMI of obese and normal individuals. Methods: Selection of obese subjects was according to the WHO (1998) criteria. A total of 40 subjects 18 - 55 years of age participated in the study, among which 30 subjects (Mean Age = 29.47 ± 1.99) were obese (Mean BMI = 35.41 ± 0.878) and 10 were controls with Mean age = 21.00 ± 0.547 and BMI = 19.96 ± 0.432. An overnight fasting blood sample was obtained and serum total Cholesterol (T-CH) level was estimated. Results: Obese persons having Mean T-CH = 202.6 ± 14.3 and controls having Mean T-CH = 173.3 ± 14.0. The data were further divided into males and females. Obese females were 11 with their BMI 31.836 ± 0.21, mean age ranged at 28.73 ± 4.04 and T-CH 191.8 ± 21.8, while that of control females were 6 in number with their BMI ranged at 19.183 ± 0.507, age 21.000 ± 0.894 and Cholester 148.7 ± 16.0 in controls. Total numbers of obese males were 19 with their BMI ranged at 37.49 ± 1.14, age ranged at 29.89 ± 2.19 and cholesterol level ranged at 208.89 ± 19.1.

Genotyping of the ApoC-Ⅲ3238C】G was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis,and then confirmed by direct sequencing.Interactions of the ApoC-Ⅲ3238C】G genotype and alcohol consumption was assessed by using a cross-product term between genotypes and the afore-mentioned factor.Results Serum total cholesterol(TC), TG,high-density lipoprotein cholesterol(HDL-C),ApoA-I and ApoB levels were higher in drinkers than in nondrinkers (P【0.05-0.001).There was no significant difference in the genotypic and allelic frequencies between the two groups. Serum TG levels in nondrinkers were higher in CG genotype than in CC genotype(P【0,01).Serum TC,TG,low-density lipoprotein cholesterol(LDL-C) and ApoB levels in drinkers were higher in GG genotype than in CC or CG genotype(P【0.01 for all).Serum HDL-C levels in drinkers were higher in CG genotype than in CC genotype(P【0.01).Serum TC, TG,HDL-C and ApoA-I levels in CC genotype,TC,HDL-C, ApoA-I levels and the ratio of ApoA-I to ApoB in CG genotype, and TC,TG,LDL-C,ApoA-I and ApoB levels in GG genotype were higher in drinkers than in nondrinkers(P【0.05-0.01).But the ratio of ApoA-I to ApoB in GG genotype was lower in drinkers than in nondrinkers(P【0.01). Multivariate logistic regression analysis showed that the levels of TC,TG and ApoB were correlated with genotype in non drinkers(P【0.05 for all).The levels of TC,LDL-C and ApoB were associated with genotype in drinkers(P【0.01 for all). Serum lipid parameters were also correlated with age,sex,alcohol consumption,cigarette smoking,blood pressure,body weight,and body mass index in both groups.Conclusions This study suggests that the ApoC-Ⅲ3238CG heterozygotes benefited more from alcohol consumption than CC and GG homozygotes in increasing serum levels of HDL-C,ApoA-I, and the ratio of ApoA-I to ApoB,and lowering serum levels of TC and TG.展开更多

The height,weight,waist circumference,blood pressure, and serum total cholesterol(TC),triglyceride(TG), high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),apolipoprotein(Apo) A1, and ApoB were measured.Body massindex(BMI,kg/m2) was calculated.Genotyping of the LDL-RAvaⅡwas performed by polymerse chain reaction and restriction fragment length polymorphism combined with gel electrophoresis,and then confirmed by direct sequencing.Results(l)The height,weight,serum TC,HDL-C,LDL-C,ApoAl levels and the ratio of ApoAl to ApoB were lower in Bai Ku Yao than in Han Chinese(P【0.01 for all),whereas the percentage of subjects who consumed alcohol or smoked cigarettes was higher in Bai Ku Yao than in Han Chinese(P【0.01 for each).(2) The frequency of A+ allele in Bai Ku Yao was 34.5%,and the frequencies of A-A-,A-A+ and A+A + genotypes were 42.6%,45.9%and 11.5%;respectively. The frequency of A+ allele in Han Chinese was 19.3%(P【0.001),and the frequencies of A-A-,A-A + and A+A+ genotypes were 64.9%,31.6%and 3.5%(P【0.001);respectively. The frequencies of A-A-,A-A+ and A+A+ genotypes in Bai Ku Yao were significant difference between males and females,between normal TC and high TC subgroup, and between normal LDL-C and high LDL-C subgroup (P【0.05 for all),whereas the frequencies of A- and A+ ? alleles in Han Chinese were significant difference between males and females(P【0.05).(3) Serum LDL-C levels in Bai Ku Yao were significant difference among the A-A-, A-A+ and A+A+ genotypes(P【0.05),the A+ carriers had higher serum LDL-C levels.Serum HDL-C levels in Han Chiese were significant difference among the A-A-,A-A + and A+A+ genotypes(P【0.01),the A+ carriers had higher serum HDL-C levels.(4) After adjusting other factors,the prevalence of LDL-C abnormality was still higher in Han Chiese than in Bai Ku Yao.The prevalence of TC abnormality in Han Chinese was almost twice high as in Bai Ku Yao. The age and diet were common risk factor for TC abnormality. No effect of AvaⅡgenotype or alcohol consumption on the TC abnormality was found,but the combination of geno-type and alcohol consumption can increase the prevalence of TC abnormality[Exp(B) =(1.154)].Age was negatively cor- related with TG level.Conclusions Serum TC and LDL-C levels were lower in Bai Ku Yao than in Han Chinese.There were significant differences in the AvaⅡallele and genotype frequencies between the he A+ carriers in Bai Ku Yao had higher serum LDL-C levels,whereas the A+ carriers in Han had higher serum HDL-C levels.Interactions between alcohol consumption or cigarette smoking and the LDL-R AvaⅡgenotype were also observed.The differences in the serum lipid profiles between the two ethnic groups might partly result from different genotypic frequency of LDL-R AvaⅡpolymorphism or differentgene-enviromental interactions.Bai Ku Yao and Han population,the frequency of A + allele was higher in Bai Ku Yao than in Han.T between the two ethnic groups.Therefore,the aim of the present study was to detect the展开更多
文摘To study the effect of IL-18 and nitric oxide(NO) on the growth and metastasis of non-small cell lung cancer (NSCLC).Methods Serum IL-18 and nitrate and nitrite levels in 82 patients with NSCLC and 20 healthy control subjects were measured by using ELISA and Griess.Results The levels of serum IL-18 were (334.2±31.0)ng/L in NSCLC patients and (151.3±22.0)ng/L in control subjects,respectively.The levels of nitrate and nitrite were (237.1±21.0)μmol/L in NSCLC patients and (44.2±15.0)μmol/L in control subjects.The levels of serum IL-18 and nitrate and nitrite were not related with age,gender,histological types in patients with NSCLC.The levels of serum IL-18 was closely associated with TNM stage,lymph node metastasis and distal metastasis,but not with its degree and organ types of metastasis.There was a negative correlation between the levels of serum IL-18 and nitrate and nitrite.Conclusion Serum IL-18 and nitrate and nitrite levels may be useful to evaluate the prognosis of the patients with NSCLC.16 refs,2 tabs.
文摘HBsAg serum level (quantification) may be useful for managing hepatitis B virus (HBV) infection patients. However few studies especially in Africa have evaluated the association between HBsAg serum level and liver fibrosis severity. The objective of this study was to estimate the correlation between HBsAg serum level and liver fibrosis severity with treatment naive chronic hepatitis B patients in Cote d’Ivoire. Methodology: It is a prospective study covering from February 1st, 2014 to April 30st, 2015 at Centre Hospitalier et Universitaire de Yopougon and a private medical office in Abidjan, Cote d’Ivoire. Inclusion criteria for patients were: HBsAg positive, known HBeAg status, serum HBsAg levels, serum HBV DNA levels, complex serum markers and absence of HCV, HDV, or HIV co-infection, drinking more than 30 g/day for men and 20 g/day in women over 10 years, metabolic disease and/or hepatic overload. Pearson’s Chi-square test (r2), Anova, Spearman, T-Student, Pearson’s (r) correlations and Mann Withney’s Test were carried out as appropriate. A p value < 0.05 was taken as significant. Results: We recruited, 105 patients (77 men) of whom the medium age was 39.01 ± 9.72 years. Predominant hepatitis B viral genotype was E (93%). Less than 10% patients had an inactive HBV in HBeAg-negative. Patients had an average high HBsAg serum level (mean 12111.2 ± 10617.4 IU/ml) as well as the one viral load (mean 4.4 e7 ± 7.5 e7). Serum ALAT levels averaged at the upper limit of normal value. The average liver fibrosis score was 0.34 ± 0.22 and the degree of viral activity was 0.19 ± 0.20. Half of our patients had no fibrosis (35.24%) or had mild fibrosis (20.95%). No significant association was observed between HBsAg serum level and patient age (p = 0.3994), genre (p = 0.8075) or serum ALT levels (p = 0, 0787). In multivariate analysis, there’s a significant correlation (r = 0.239, p = 0.014) between HBV DNA levels and HBsAg serum level. There’s a significant correlation (r = 0.923, p < 0.0001) between HBsAg serum level and the dosage of alpha-fetoprotein. HBsAg serum level was not associated with the fibrosis stage (p = 0.281). HBsAg levels average with patients without fibrosis or carry a slight fibrosis (F0, F1) was higher than patients with moderate to severe fibrosis (F2, F3, F4): 13679.2 UI/ml ± 1956.48 versus 10610.52 UI/ml ± 8998.99 (p = 0.29). There’s a negative correlation between HBsAg level and the liver fibrosis score was negative (r = -0.069, p = 0.48). No significant association between HBsAg level and the liver fibrosis patients that were normal (p = 0.7965) or elevated (p = 0.5845). HBV DNA level was significantly associated with fibrosis score (r = 0.30, p = 0.0018). Conclusion: This study shows that there’s a negative correlation between HBsAg serum level and liver fibrosis severity treatment naive with African chronic hepatitis B viral HBeAg-negative patients.
文摘BACKGROUND Speech disorders have a substantial impact on communication abilities and quality of life.Traditional treatments such as speech and psychological therapies frequently demonstrate limited effectiveness and patient compliance.Transcranial electrical stimulation(TES)has emerged as a promising non-invasive treatment to improve neurological functions.However,its effectiveness in enhancing language functions and serum neurofactor levels in individuals with speech disorders requires further investigation.AIM To investigate the impact of TES in conjunction with standard therapies on serum neurotrophic factor levels and language function in patients with speech disorders.METHODS In a controlled study spanning from March 2019 to November 2021,81 patients with speech disorders were divided into a control group(n=40)receiving standard speech stimulation and psychological intervention,and an observation group(n=41)receiving additional TES.The study assessed serum levels of ciliary neurotrophic factor(CNTF),glial cell-derived neurotrophic factor(GDNF),brainderived neurotrophic factor(BDNF),and nerve growth factor(NGF),as well as evaluations of motor function,language function,and development quotient scores.RESULTS After 3 wk of intervention,the observation group exhibited significantly higher serum levels of CNTF,GDNF,BDNF,and NGF compared to the control group.Moreover,improvements were noted in motor function,cognitive function,language skills,physical abilities,and overall development quotient scores.It is worth mentioning that the observation group also displayed superior perfor CONCLUSION This retrospective study concluded that TES combined with traditional speech and psychotherapy can effectively increase the levels of neurokines in the blood and enhance language function in patients with speech disorders.These results provide a promising avenue for integrating TES into standard treatment methods for speech disorders.

文摘BACKGROUND The excessive concentration of leptin has negative effects on all aspects of female reproduction.Despite this established relationship,the exact role of leptin in women’s fertility is not clear enough and needs more clarification.AIM To evaluate the serum leptin levels in Sudanese women and to ascertain the relationship between serum leptin levels and unexplained infertility(UI).METHODS A matched(age and body mass index)case-control study was conducted from March 2021 to February 2022.The study samples were 210 women with UI and 190 fertile women of reproductive age who were attending the maternity hospitals and fertility clinics in Khartoum state Sudan.The serum concentration of leptin and other serum biomarkers were determined using enzyme-linked immunosorbent assays.RESULTS The results showed that there was a highly statistically significant difference between the two groups(P<0.001)for all examined eight biomarkers.Whereby,leptin,luteinizing hormone(LH)/follicular stimulating hormone(FSH)ratio,prolactin hormone(PRL)and testosterone(T)were significantly higher in the UI group compared with the control group.In contrast,FSH and estradiol(E2)/T ratio were significantly lower in the UI group than in the control group and the effect size test for the difference between the two groups was very large(effect size>0.80),for leptin level,LH/FSH ratio,PRL level,and E2/T ratio,and large(effect size 0.50-≤0.80)for FSH and T.CONCLUSION This study reveals that leptin could be a potential biomarker for UI in Sudanese women and it may be useful for identifying women with a high risk of infertility.
文摘Objective To explore the effects of enhanced external counterpulsation(EECP)on the serum level of C-reactive protein and endothelin-1 in patients with cerebral ischemic stroke,to provide clinical evidence for the treatment and secondary prevention of patients with serebral ischemic stroke.Methods Total 187 patients with ischemic stroke and enrolled measure the serum level
文摘BACKGROUND Gestational diabetes mellitus(GDM)is a concern due to its rapid increase in incidence in recent years.AIM To investigate the correlation and predictive value of serum pregnancyassociated plasma protein A(PAPP-A),triglyceride(TG),and 25-hydroxyvitamin D[25-(OH)D]with GDM in early pregnancy.METHODS A total of 99 patients in early pregnancy admitted to Peking University International Hospital from November 2015 to September 2017 were included,and underwent a fasting glucose test and oral glucose tolerance test screening at 24-28 wk of pregnancy.Of these cases with GDM,51 were assigned to group A and the remaining 48 cases without GDM were enrolled in group B.Serum PAPP-A,TG and 25-(OH)D in the two groups were compared and their correlation with blood sugar was analyzed.In addition,their diagnostic value in GDM was determined using receiver operating characteristic(ROC)curve analysis.RESULTS Group A had markedly lower serum PAPP-A and 25-(OH)D levels and a significantly higher serum TG level than group B,with statistical significance(P<0.05).Furthermore,Pearson analysis identified that PAPP-A and 25-(OH)D levels were negatively correlated with fasting blood glucose(FBG)levels(r=-0.605,P<0.001),(r=-0.597,P<0.001),while TG and FBG levels were positively correlated(r=0.628,P<0.001).The sensitivity,specificity,area under the curve(AUC)and optimal cut-off value of serum PAPP-A level in the diagnosis of GDM were 72.55%,82.35%,0.861 and 16.340,respectively,while the sensitivity of TG in diagnosing GDM was 86.27%,the specificity was 66.67%,the AUC was 0.813,with an optimal cut-off value of 1.796.The corresponding sensitivity,specificity,AUC and optimal cut-off value of serum 25-(OH)D were 64.71%,70.59%,0.721 and 23.140,respectively.Moreover,multivariate logistic regression analysis revealed that FBG,vascular endothelial growth factor,Flt-1,serum PAPP-A,TG,and 25-(OH)D were related risk factors leading to GDM in patients.CONCLUSION Serum PAPP-A,TG,and 25-(OH)D levels are all correlated with blood glucose changes in GDM,and are independent factors affecting the occurrence of GDM and have certain value in the diagnosis of GDM.
文摘Background The association of E670G polymorphism in the proprotein convertase subtilisin/kexin type 9 (PCSK9) gene and serum lipid profiles is inconsistent in dif- ferent ethnic groups.Bai Ku Yao is a special subgroup of the Yao minority in China.The present study was undertaken association of PCSK9 E670G polymorphism and several environmental factors with serum lipid levels in the Guangxi Bai Ku Yao and Han populations.Methods A total of 649 subjects of Bai Ku Yao and 646 participants of Han Chinese were randomly selected from our previous stratified randomized cluster samples.Genotyping of the PCSK9 E670G polymorphism was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis,and then confirmed by direct sequencing. Results The levels of serum total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C) and apolipoprotein(Apo) AI were lower in Bai Ku Yao than in Han(P【0.01 for all).The frequency of A and G alleles was 98.00%and 2.00%in Bai Ku Yao,and 95.20%and 4.80%in Han(P【0.01);respectively. The frequency of AA,AG and GG genotypes was 95.99%,4.01%and 0%in Bai Ku Yao,and 91.02%, 8.36%and 0.62%in Han(P【0.01);respectively.There were also significant differences in the genotypic and allelic frequencies between n and the ratio of ApoAI to ApoB in Han Chinese but not in Bai Ku Yao were different between the AA and AG/GG genotypes(P【0.05 for all).The G allele carriers had higher serum HDL-C and higher ApoAI to ApoB ratio than the G allele noncarriers.When serum lipid parameters in Han were analyzed according to sex,the G allele carriers had higher serum HDL and ApoAI levels in males (P【0.05),and lower ApoB level and higher ApoAI to ApoB ratio in females(P【0.05 for all).Multiple linear regression analysis showed that serum HDL-C levels were correlated with genotypes in both ethnic groups(P【0.05 each).Serum lipid parameters were also correlated with sex,age,body massindex,alcohol consumption,cigarette smoking,and blood pressure in both ethnic groups(P【0.05-0.001).Conclusions These results suggest that the PCSK9 E670G polymorphism is mainly associated with some serum lipid parameters in the Han population,both gender show different relations to different serum lipid parameters.The G allele carriers might have higher serum lipid profiles than the G allele noncarriers. ormal LDL-C(≤3.20 mmol/L) and high LDL-C subgroups (】 3.20 mmol/L,P【0.01;respectively) in Bai Ku Yao, and between normal ApoB(≤1.14 g/L) and high ApoB subgroups(】 1.14 g/L,P 【 0.01;respectively) in Han.
文摘Objectives Apolipoprotein(Apo) A5 gene poly-morphisms and alcohol consumption have been associated with increased serum triglyceride(TG) levels,but little is known about their interactions on serum lipid levels.The present study was undertaken polymorphismsand alcohol consumption on serum lipid levels.Methods A total of 516 unrelated nondrinkers and 514 drinkers aged 15 -89 were randomly selected from our previous stratified randomized cluster samples.Genotyping of the ApoA5was performed by polymerase chain reaction and restriction fragment length polymorphism,and then confirmed by direct sequencing.Interactions of the ApoA5alcohol consumption were assessed by using a cross-product term between genotypes and the aforementioned factor.Results The levels of total cholesterol (TC),TG,high-density lipoprotein cholesterol(HDL-C), ApoA1 and ApoB were higher in drinkers than in nondrinkers (P【0.05-0.001).The genotypic and allelic frequencies of the three single nucleotide polymorphisms(SNPs) were not different between the two groups.The levels of TG in non-drinkers, and TC,TG,low-density lipoprotein cholesterol (LDL-C)and ApoB in drinkers were different among the three -1131T】C genotypes(P【0.05-0.001).The -1131C allele carriers had higher serum TC,TG,LDL-C and ApoB levels than the allele noncarriers.The levels of TG,HDL-C and ApoB in nondrinkers,and TG and HDL-C in drinkers were different between the two c.553G】T genotypes(P【0.05-0.01).The C.553T allele carriers had higher serum TG and ApoB levels,and lower HDL-C levels than the allele noncarriers.Serum lipid levels in nondrinkers were not different among the three c.457G】A genotypes(P【0.05 for all), but the levels of HDL-C,LDL-C,ApoA1 and ApoB in drinkers were different between the GG and GA/AA geno-types (P【0.05-0.001).The C.457A allele carriers had lower serum HDL-C,LDL-C,ApoAl and ApoB levels than the allele noncarriers.We also observed four haplotypes:G-G-T, G-G-C,G-A-T,and T-G-C with frequencies ranging from 0.06 to 0.87,representing 100%of all haplotypes in the both populations.The ApoA5 haplotypes were significantly(P【0.05) associated at the global level with TC,TG,HDL-C, LDL-C,Apo1,and ApoB,even after correction for multiple testing with permutation test.In particular,carriers of haplo-type G-G-C had significantly higher TC,TG,LDL-C,ApoB than noncarriers,whereas carriers of haplotype C-A-T had significantly lower TC,LDL-C,ApoAl and ApoB,and higher HDL-C than noncarriers.Serum TC levels in nondrinkers were correlated with -1131T】C genotype and allele(P【0.05 for each),whereas serum TC,TG and LDL-C levels in drinkers were associated with -1131 T】C and C.553G】T genotypes,or c.457G】A alleles(P【0.05-0.001).Serum lipid parameters were also correlated with several environmental factors in the both groups.Conclusions The differences in serum lipid profiles between the drinkers and nondrinkers might partly result from different interactions of ApoA5 gene polymor phisms and alcohol consumption.genotypes and -1131T】C, c.553G】T and c.457G】A to detect the interactions of the ApoA5
文摘Objectives The association of methylenetetrahy-drofolate reductase(MTHFR) gene polymorphism and serum lipid profiles is still controversial in diverse ethnics.Bai Ku Yao is an isolated subgroup of the Yao minority in China. The aim of the present study was to eveluate the association of MTHFR C677Tpolymorphism and several environmental factors with serum lipid levels in the Guangxi Bai Ku Yao and Han populations.Methods A total of 780 subjects of Bai Ku Yao and 686 participants of Han Chinese were randomly selected from our previous stratified randomized cluster samples.Genotyping of the MTHFR C677T was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis,and then confirmed by direct sequencing.Results The levels of serum total cholesterol(TC),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol(LDL-C), apolipoprotein(Apo) AI and ApoB were lower in Bai Ku Yao than in Han(P【0.05-0.001).The frequency of C and T alleles was 77.4%and 22.6%in Bai Ku Yao,and 60.9%and 39.1%in Han(P【0.001);respectively.The frequency of CC,CT and TT genotypes was 58.7%,37.3%and 4.0%in Bai Ku Yao,and 32.6%,56.4%and 11.0%in Han(P【 0.001);respectively.The levels of TC and LDL-C in both ethnic groups were significant differences among the three genotypes(P【0.05-0.01).The T allele carriers had higher serum TC and LDL-C levels than the T allele noncarriers. The levels of ApoB in Han were significant differences among the three genotypes(P【0.05).The T allele carriers had higher serum ApoB levels as compared with the T allele noncarriers. The levels of TC,TG and LDL-C in Bai Ku Yao were correlated with genotypes(P【0.05-0.001),whereas the levels of LDL-C in Han were associated with genotypes(P【 0.001).Serum lipid parameters were also correlated with sex, age,body massindex,alcohol consumption,cigarette smoking, and blood pressure in the both ethnic groups.Conclusions The differences in serum TC,TG,LDL-C and ApoB levels between the two ethnic groups might partly result from different genotypic and allelic frequencies of the MTHFR C677Tor differentMTHFR gene-enviromental interactions.
文摘Objective:To investigate the changes and the corresponding clinical value of serum cortisol levels in patients with hypertensive disorders during pregnancy.Methods:In this study,90 patients with different degrees of hypertensive disorders during pregnancy who were admitted from August 2018 to August 2019 in our hospital were set as the research objects.90 cases were grouped according to the diagnostic criteria in Obstetrics and Gynecology,including 30 cases in each of the hypertension group,the preeclampsia group,and the eclampsia group.Another 30 healthy pregnant women were selected as the control group.The serum cortisol levels of pregnant women in the above four groups were measured.Results:Compared with the control group,the serum cortisol levels in the other three groups were significantly increased.In perinatal outcome,compared with the control group,the three groups of patients had an increase in Apgar score,preterm birth,stillbirth rate,growth restriction rate and neonatal asphyxia rate.There were significant differences between groups(P<0.05),and showed as gestational hypertension<preeclampsia<eclampsia.Conclusion:With the exacerbation of hypertensive disorders during pregnancy,the serum cortisol level continues to increase,which has a serious adverse effect on the prognosis of the perinatal infants.
文摘Diabetes mellitus is one of the worldwide largest growing metabolic diseases. In this study the effects of consumption of raw garlic on serum lipid level, blood sugar and a number of effective hormones on lipid and sugar metabolism (thyroid hormones and insulin) in individuals either with high level of blood sugar or lipid were investigated. Eighty five volunteers having following clinical history enrolled in the study: Group 1: having blood sugar more than 126 mg/dl (30 vo-lunteers);Group 2: having cholesterol higher than 245 mg/dl (30 volunteers);Group 3: having blood sugar over 126 mg/dl and cholesterol more than 245 mg/dl (25 volunteers). In group 1, there wasn’t a sig-nificant differences between biochemical factors be-fore and after garlic consumption, whereas, in the second group after 6 weeks of garlic consumption a decline in cholesterol (P < 0.001), FBS and TG (P < 0.01) was observed but HDL-C (P < 0.001) was in-creased. Six weeks after termination of garlic con-sumption, cholesterol (P < 0.001), FBS and TG (P < 0.05) were in- creased and HDL-C (P < 0.01) was de-creased. In the third group, total cholesterol (P < 0.001), FBS (P < 0.01) and HbA1c decreased while HDL-C was in- creased. Other factors, including thy-roid hormones (T3, T4), TSH and insulin showed no significant alte- ration. In conclusion our results shown that raw garlic consumption can reduce the FBS and Lipid in hyperglycemic and/or hyperlipidemic individuals.
文摘BACKGROUND Iron plays an important role in neurodevelopmental functions in the brain.Serum ferritin levels are different in children with attention deficit hyperactivity disorder and tic disorder than in healthy children.AIM To explore the current status of iron deficiency in children with neurodevelopmental disorders and its sex and age effects.METHODS A total of 1565 children with attention deficit hyperactivity disorder(ADHD),1694 children with tic disorder(TD),93 children with ASD and 1997 healthy control children were included between January 1,2020,and December 31,2021 at Beijing Children's Hospital.We describe the differences in age levels and ferritin levels between different disease groups and their sex differences.The differences between the sexes in each disease were analyzed using the t test.The incidence rate of low serum ferritin was used to describe the differences between different diseases and different age groups.A chi-square test was used to analyze the difference in the incidence of low serum ferritin between the disease group and the control group.Analysis of variance was used for comparisons between subgroups,and regression analysis was used for confounding factor control.RESULTS A total of 1565 ADHD patients aged 5-12 years were included in this study,and the average serum ferritin levels of male and female children were 36.82±20.64μg/L and 35.64±18.56μg/L,respectively.A total of 1694 TD patients aged 5-12 years were included in this study,and the average serum ferritin levels of male and female children were 35.72±20.15μg/L and 34.54±22.12μg/L,respectively.As age increased,the incidence of low serum ferritin in ADHD and TD first decreased and then increased,and 10 years old was the turning point of rising levels.The incidence of ADHD with low serum ferritin was 8.37%,the incidence of TD with low serum ferritin was 11.04%,and the incidence of the healthy control group with low serum ferritin was 8.61%,among which male children with TD accounted for 9.25%and female children with TD accounted for 11.62%.There was a significant difference among the three groups(P<0.05).In addition,there were 93 children with ASD with an average serum ferritin level of 30.99±18.11μg/L and a serum ferritin incidence of 15.05%.CONCLUSION In conclusion,low serum ferritin is not a risk factor for ADHD or TD.The incidence of low serum ferritin levels in children with ADHD and TD between 5 and 12 years old decreases first and then increases with age.
文摘Background Elevated serum phosphorus levels may be associated with adverse outcomes in cardiovascular disease. This study aimed to investigate the relation between serum phosphorus levels and risk of all-cause mortality in Chinese patients with ST-segment elevation myocardial infarction (STEMI) who had preserved renal function at baseline. Methods We enrolled patients with STEMI who had preserved renal function at baseline in Xuanwu Hospital from January 2011 to December 2016. Those patients were divided into four groups based on serum phosphorus levels. All-cause mortality rates were compared between groups. Mean duration of follow up was 54.6 months. We used Cox proportional-hazards models to examine the relation between serum phosphorus levels and all-cause mortality after adjustment for potential confounders. Results 1989 patients were involved and 211 patients (10.6%) died during follow-up. Based on serum phosphorus levels, patients were categorized into the following groups:< 2.50 mg/dL (n = 89), 2.51–3.50 mg/dL (n = 1066), 3.51–4.50 mg/dL (n = 672) and > 4.50 mg/dL (n = 162), respectively. The lowest mortality occurred in patients with serum phosphorus levels between 2.51–3.50 mg/dL, with a multivariable-adjusted hazard ratio of 1.19 (95% CI: 0.64–1.54), 1.37 (95% CI: 1.22–1.74), and 1.46 (95% CI: 1.35–1.83) in patients with serum phosphorus levels of < 2.50 mg/dL, 3.51–4.50 mg/dL and > 4.50 mg/dL, respectively. Conclusions Elevated serum phosphorus levels were associated with all-cause mortality in Chinese patients with STEMI who had preserved renal function at baseline.
文摘The purpose of this study was to assess the correlation between iron deficiency and recurrent aphthous ulceration (RAU). Radioimmunoassay was used to examine the serum ferritin level (SFL) in 52 patients with RAU and in 54 controls. Both were divided into 2 groups in accordance with sex. The 36 female patients were subdivided into 3 age-groups as follows: 8 aged 22-24, 10 aged 25-34, and 18 aged 35-50 while the male patients were gathered as one single group aged 26-57. The subdivision was adapted similarly for the normal age-grouts. Although no significant difference in SFL was found between the male control and the male patient groups, differences between the female control and female patient groups showed highly significant which levels, with the ascendance of age, were P【0.001, P【0.005 and P【0.001, respectively. Also the difference between male and female control groups were significant (P【0.05). However, no significant differences in SFL were discovered among the 3 patient groups. 10 female patients with SFL【12ng/ml were tested with ferrous sulfate for one month, then their SFL was reexamined one week after the treatment. A highly significant difference in SFL was noted between the pre-ad post-treatment (P【0.001). 9 of them showed that the interval of recurrences were prolonged, the number of ulcers reduced, the pain less intensive and its duration shorter than those before the treatment. This study demonstrated that a singificant decrease in iron-storage occurred in female RAU patients. The authors concluded that the decrease SFL was possibly related to menstruation and child bearing.
文摘Background: The present study was planned to investigate the level of cholesterol in obese/non-obese (normal) individuals according to their body mass index (BMI) and age in different population residing in Karachi. Aim: Comparison of serum cholesterol values of obese with normal subjects and comparison of BMI of obese and normal individuals. Methods: Selection of obese subjects was according to the WHO (1998) criteria. A total of 40 subjects 18 - 55 years of age participated in the study, among which 30 subjects (Mean Age = 29.47 ± 1.99) were obese (Mean BMI = 35.41 ± 0.878) and 10 were controls with Mean age = 21.00 ± 0.547 and BMI = 19.96 ± 0.432. An overnight fasting blood sample was obtained and serum total Cholesterol (T-CH) level was estimated. Results: Obese persons having Mean T-CH = 202.6 ± 14.3 and controls having Mean T-CH = 173.3 ± 14.0. The data were further divided into males and females. Obese females were 11 with their BMI 31.836 ± 0.21, mean age ranged at 28.73 ± 4.04 and T-CH 191.8 ± 21.8, while that of control females were 6 in number with their BMI ranged at 19.183 ± 0.507, age 21.000 ± 0.894 and Cholester 148.7 ± 16.0 in controls. Total numbers of obese males were 19 with their BMI ranged at 37.49 ± 1.14, age ranged at 29.89 ± 2.19 and cholesterol level ranged at 208.89 ± 19.1. Control males were 4 in number with their BMI ranged at 21.125 ± 0.075, age 21.250 ± 0.479 and their T-CH 128.7 ± 8.72. Conclusion: The results of current study have reflected that BMI and total cholesterol concentration are higher in obese subjects.
文摘Objective:To investigate the effect of serum cortisol level on perinatal prognosis in patients with hypertensive disorder during pregnancy.Methods:In this study,different degrees of patients with hypertensive disorder during pregnancy who were admitted from August 2018 to August 2019 in our hospital were selected as the research subjects,and divided into groups according to the severity of the patients’conditions.The 120 patients were divided into gestational hypertension group,preeclampsia group and eclampsia group,with 40 cases each,and another 40 healthy pregnant women were selected.The detection of serum cortisol levels was carried out for the above 4 groups of pregnant women.Results:The serum cortisol level in the control group was(260.35±10.96)nmol/L.The case number of neonatal asphyxia was 1(2.50%),the case number of premature births was 1(2.50%),the number of fetal growth restriction was 1(2.50%),the number of deaths was 0,and the other three groups were higher than this.It showed as gestational hypertension<preeclampsia<eclampsia.The Apgar score of pregnant women in the control group was(9.13±0.29),the ZL index was(1.07±0.07),and the other three groups were lower than this.It showed as gestational hypertension>preeclampsia>eclampsia.There were significant differences between groups(all P<0.05).Conclusion:Early detection of serum cortisol levels in pregnant women is beneficial to timely improve the symptoms of gestational hypertension,thereby suppressing the effects of serum cortisol on perinatal infants and improving the prognosis of newborns.
文摘Objectives Both apolipoprotein(Apo)C-Ⅲgene polymorphism and alcohol consumption have been associated with increased serum triglyceride(TG) levels,but their interactions on serum TG levels are not well known.The present study was undertaken to detect the interactions of the ApoC-Ⅲ3238C】G(rs5128) polymorphism and alcohol consumption on serum TG levels.Methods A total of 516 unrelated nondrinkers and 514 drinkers aged 15-89 were randomly selected from our previous stratified randomized cluster samples. Genotyping of the ApoC-Ⅲ3238C】G was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis,and then confirmed by direct sequencing.Interactions of the ApoC-Ⅲ3238C】G genotype and alcohol consumption was assessed by using a cross-product term between genotypes and the afore-mentioned factor.Results Serum total cholesterol(TC), TG,high-density lipoprotein cholesterol(HDL-C),ApoA-I and ApoB levels were higher in drinkers than in nondrinkers (P【0.05-0.001).There was no significant difference in the genotypic and allelic frequencies between the two groups. Serum TG levels in nondrinkers were higher in CG genotype than in CC genotype(P【0,01).Serum TC,TG,low-density lipoprotein cholesterol(LDL-C) and ApoB levels in drinkers were higher in GG genotype than in CC or CG genotype(P【0.01 for all).Serum HDL-C levels in drinkers were higher in CG genotype than in CC genotype(P【0.01).Serum TC, TG,HDL-C and ApoA-I levels in CC genotype,TC,HDL-C, ApoA-I levels and the ratio of ApoA-I to ApoB in CG genotype, and TC,TG,LDL-C,ApoA-I and ApoB levels in GG genotype were higher in drinkers than in nondrinkers(P【0.05-0.01).But the ratio of ApoA-I to ApoB in GG genotype was lower in drinkers than in nondrinkers(P【0.01). Multivariate logistic regression analysis showed that the levels of TC,TG and ApoB were correlated with genotype in non drinkers(P【0.05 for all).The levels of TC,LDL-C and ApoB were associated with genotype in drinkers(P【0.01 for all). Serum lipid parameters were also correlated with age,sex,alcohol consumption,cigarette smoking,blood pressure,body weight,and body mass index in both groups.Conclusions This study suggests that the ApoC-Ⅲ3238CG heterozygotes benefited more from alcohol consumption than CC and GG homozygotes in increasing serum levels of HDL-C,ApoA-I, and the ratio of ApoA-I to ApoB,and lowering serum levels of TC and TG.
文摘Objectives Bai Ku Yao(White-trousers Yaos)is a special branch of Yao minority in China.They are now living in both Lihu and Baxu villages,Nandan County, Guangxi,China.The population size is about 30,000.The special customs and culture of Bai Ku Yao,including their special clothing,intra-ethnic marriages and alcohol intake are still completely conserved to the present day.In previous epidemiologic studies,we found that the serum lipid levels and the prevalence of hyperlipidaemia were lower in Bai Ku Yao than in Han Chinese from the same region.This ethnic difference in serum lipid profiles is still not well known.We hypothesized that there may be significant differences in some genetic polymorphismsssociation of low density lipoprotein receptor (LDL-R) genepolymorphism and several environmental factors with serum lipid levels in the Guangxi Bai Ku Yao and Han populations.Methods A total of 1024 subjects of Bai Ku Yao and 792 participants of Han Chinese were stud- ied by a stratified randomized cluster sampling.Epidemiological survey was carried out using internationally standardized methods.Information on demographics,socioeconomic status, and lifestyle factors was collected with standardized questionnaires. The height,weight,waist circumference,blood pressure, and serum total cholesterol(TC),triglyceride(TG), high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),apolipoprotein(Apo) A1, and ApoB were measured.Body massindex(BMI,kg/m2) was calculated.Genotyping of the LDL-RAvaⅡwas performed by polymerse chain reaction and restriction fragment length polymorphism combined with gel electrophoresis,and then confirmed by direct sequencing.Results(l)The height,weight,serum TC,HDL-C,LDL-C,ApoAl levels and the ratio of ApoAl to ApoB were lower in Bai Ku Yao than in Han Chinese(P【0.01 for all),whereas the percentage of subjects who consumed alcohol or smoked cigarettes was higher in Bai Ku Yao than in Han Chinese(P【0.01 for each).(2) The frequency of A+ allele in Bai Ku Yao was 34.5%,and the frequencies of A-A-,A-A+ and A+A + genotypes were 42.6%,45.9%and 11.5%;respectively. The frequency of A+ allele in Han Chinese was 19.3%(P【0.001),and the frequencies of A-A-,A-A + and A+A+ genotypes were 64.9%,31.6%and 3.5%(P【0.001);respectively. The frequencies of A-A-,A-A+ and A+A+ genotypes in Bai Ku Yao were significant difference between males and females,between normal TC and high TC subgroup, and between normal LDL-C and high LDL-C subgroup (P【0.05 for all),whereas the frequencies of A- and A+ ? alleles in Han Chinese were significant difference between males and females(P【0.05).(3) Serum LDL-C levels in Bai Ku Yao were significant difference among the A-A-, A-A+ and A+A+ genotypes(P【0.05),the A+ carriers had higher serum LDL-C levels.Serum HDL-C levels in Han Chiese were significant difference among the A-A-,A-A + and A+A+ genotypes(P【0.01),the A+ carriers had higher serum HDL-C levels.(4) After adjusting other factors,the prevalence of LDL-C abnormality was still higher in Han Chiese than in Bai Ku Yao.The prevalence of TC abnormality in Han Chinese was almost twice high as in Bai Ku Yao. The age and diet were common risk factor for TC abnormality. No effect of AvaⅡgenotype or alcohol consumption on the TC abnormality was found,but the combination of geno-type and alcohol consumption can increase the prevalence of TC abnormality[Exp(B) =(1.154)].Age was negatively cor- related with TG level.Conclusions Serum TC and LDL-C levels were lower in Bai Ku Yao than in Han Chinese.There were significant differences in the AvaⅡallele and genotype frequencies between the he A+ carriers in Bai Ku Yao had higher serum LDL-C levels,whereas the A+ carriers in Han had higher serum HDL-C levels.Interactions between alcohol consumption or cigarette smoking and the LDL-R AvaⅡgenotype were also observed.The differences in the serum lipid profiles between the two ethnic groups might partly result from different genotypic frequency of LDL-R AvaⅡpolymorphism or differentgene-enviromental interactions.Bai Ku Yao and Han population,the frequency of A + allele was higher in Bai Ku Yao than in Han.T between the two ethnic groups.Therefore,the aim of the present study was to detect the
