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

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.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

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

The association between the risk of the incidence of ovarian cancer and the alterations in the levels of blood glucose and serum lipids is not well defined. Objective: In this study we aimed to compare the levels of blood glucose, triacylglycerols, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol in patients with different stages of ovarian cancer and healthy controls to determine how they relate to the risk and prognosis of ovarian cancer. Methodology: In a case-control cross sectional study, we enrolled ninety-nine Sudanese women, diagnosed with ovarian cancer but had not received any kind of treatment as the study group, and a control group of forty-one age-matched, apparently healthy women. The patients were classified according to the International Federation of Obstetricians and Gynecologists staging system into two groups: early stages (stage I & II) and late stages (stages III & IV). Blood glucose and serum lipids;triacylglycerols, total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol were determined by enzymatic colorimetric methods using commercially available analytical kits. The IBM SPSS version 20 software was used for statistical analysis. A Mann-Whitney U test was used for comparison of the median concentrations of blood glucose, triacylglycerols, total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol in the study groups. Logistic regression model was used to estimate the relative risk of ovarian cancer in relation to levels of blood glucose and serum lipids. P value of 0.05 was considered significant. Results: Our data indicated significantly higher levels of blood glucose (p < 0.001), triacylglycerols (p = 0.002), and low-density lipoprotein cholesterol (p < 0.001), and lower levels of high-density lipoprotein cholesterol (p = 0.023), in ovarian cancer patients compared to the control subjects. No significant difference was found in the levels of blood glucose or any of the serum lipids between patients in the early stages (stage I & II) and those in late stages (stage III & IV) of ovarian cancer. The logistic regression analysis indicated significant association between the elevated levels of the blood glucose, triacylglycerols and low-density lipoprotein cholesterol and the risk of the ovarian cancer. Conclusion: We conclude that the levels of blood glucose, triacylglycerols, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol differ significantly between ovarian cancer patients and the healthy control subjects. The risk of ovarian cancer was positively associated with the levels of blood glucose, triacylglycerols and low-density lipoprotein cholesterol, and negatively associated with levels of high-density lipoprotein cholesterol. Therefore, determination of blood glucose and serum lipids, particularly, triacylglycerols, low-density lipoprotein cholesterol may be helpful as diagnostic indicators of ovarian cancer (OC).展开更多

DM-related dyslipidemia are associated with complications resulting from progressive damage of various organs. CD36 is 88-kD, class B scavenger receptor, expressed on different types of cells. In diabetic patients, LDL particles are glycated with strong level;this increases CD36 expression, initiates foam cell formation and accelerates atherosclerosis. Objective: This study aimed to determine the correlation between serum CD36 level and lipid profile among patients with type 2 diabetes mellitus in Zeenam Specialized center, Khartoum State, Sudan, in a period between 2019 and 2022. Methodology: Hundred participants at different ages were included in this study;70 were type 2 diabetic patients (cases) and 30 apparently healthy individual (control). 3 ml of venous blood were collected from the participants by using a sterile needle and syringe into a labeled plain container. Each sample was stood until complete clot occurs. Clotted blood sample was then centrifuged to obtain the serum. Then they were used for measurement of total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride and soluble CD36 levels. Total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides were measured using Biosystem chemistry analyzer BTS-302. Serum CD36 was measured using Microplate Reader (URIT-660). Results: The results revealed that serum total cholesterol, LDL cholesterol, HDL cholesterol, and triglyceride levels were significantly higher in patients with type 2 diabetes mellitus compared with control (P = 0.03, P = 0.031, P = 0.000, P = 0.000) respectively, while there is no statistically significant differences in serum CD36 level between cases and control (P = 0.129). Also this study showed that there is no statistically significant correlation between serum CD36 level and total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, age and body mass index.

The aim of this study is to determine prevalence of dyslipidemia with respect to age and gender and assess the association between height increase and serum lipid changes in Cameroon children. Methods: This hospital-based cross-sectional analysis included 472 boys and 534 girls between the ages of 5 and 16 years. Body height, weight, and waist circumference (WC) of children were measured and z-scores calculated. Total cholesterol-TC, triglycerides-TG, low density lipoprotein cholesterol-LDL-C and high-density lipoprotein cholesterol-HDL-C concentrations in fasting blood samples were determined by enzymatic method using an automated clinical chemistry analyzer (RX Monaco, UK). Children were divided into increasing quartiles of height z-score. Multiple linear regression analysis was used to compare mean lipid concentrations across quartiles of height z-score after controlling for age, gender, body weight, WC and fasting blood glucose. Results: The prevalence of elevated TC and LDL-C were respectively 18.5% and 19.2% higher in girls than boys. Also, the prevalence of elevated TC and TG was highest among younger (5- to 9-year-old) girls and boys respectively. There was a significant decrease in mean TC (168.8 to 127.2 mg/dl;p p = 0.019) and LDL-C (91.1 to 69.4 mg/dl;p = 0.018) in boys;and a significant decrease in mean TC (171.2 to 144.7 mg/dl;p = 0.004) and HDL-C (62.8 to 28.7 mg/dl;p p = 0.053) and the decrease in TG (p = 0.211) and LDL-C (p = 0.732) in girls with increasing height were not significant. Conclusion: Serum lipids decreased with increasing height after controlling for different variables. This study indicates that short children have higher serum lipid concentrations and this may increase the risk of lipid disorders, which may persist into adulthood.展开更多

文摘BACKGROUND Tenofovir alafenamide(TAF)has a serum lipid-raising effect in patients with HIV;however,its effect on serum lipids and nonalcoholic fatty liver disease(NAFLD)risk in patients with chronic hepatitis B(CHB)is unclear.AIM To compare the effects of TAF and entecavir(ETV)on serum lipid levels in patients with CHB.METHODS In this retrospective cohort study,the data including the clinical features,serum lipids,and metabolic factors of patients with CHB at baseline and approximately 1 year after TAF or ETV treatment were collected and analyzed.We used propensity score-matched models to assess the effects on high-density lipoprotein,lowdensity lipoprotein,triglycerides,and total cholesterol(TCHO).RESULTS A total of 336 patients(75.60%male)were included;63.69%received TAF and 36.31%received ETV.Compared with the ETV group,the TAF group had significantly higher TCHO levels after treatment(4.67±0.90 vs 4.36±1.05,P=0.006).In a propensity score-matched model for body mass index,age,sex,smoking,drinking,presence of comorbidities such as NAFLD,cirrhosis,diabetes mellitus,and hypertension,TAF-treated patients had significantly increased TCHO levels compared to that at baseline(P=0.019).There was no difference for the ETV group.Body mass index,sex,hypertension,baseline TCHO,and creatine kinase-MB isoenzyme levels were significantly associated with elevated TCHO levels in logistic regression analysis.However,1-year TAF treatment did not increase the incidence of NAFLD.CONCLUSION A greater increase in TCHO was observed in patients with CHB receiving TAF compared to those receiving ETV.However,TAF-induced dyslipidemia did not increase the incidence of NAFLD.
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 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

The levels of LDL-C,ApoB and the ratio of ApoAI to ApoB in Bai Ku Yao were different among the three genotypes in females but not in males(P【0.05 for all).The subjects with TT and TC genotypes had lower serum LDL-C and ApoB levels and higher the ratio of ApoAI to ApoB than the CC genotype in females.The levels of TC and ApoB in the total Han population were different among the three genotypes (P【0.05 for all).The C allele carriers had higher serum TC and ApoB levels than the C allele noncarriers.When serum lipid levels were analyzed according to sex,the difference in serum TC levels in Han was significant in males(P【0.01) but not in females,whereas the difference in serum ApoB levels was significant in females(P【0.05)but not in males. Serum TC and ApoB levels were correlated with genotypes in Han(P【0.05 for each) but not in Bai Ku Yao.Serum lipid parameters were also correlated with sex,age,body massindex, alcohol consumption,cigarette smoking,and blood pressure in both ethnic groups.Conclusions These results suggest that the association of PPARD +294T】C polymorphism and serum lipid levels is different between the Bai Ku Yao and Han populations.The discrepancy between the two ethnic groups might partly result from different PPARD +294T】C polymorphism or PPARD gene-enviromental interactions,subgroup of the Yao minority in China.
文摘Objectives Endotheliallipase(EL) is a major determinantof high-density lipoprotein-cholesterol(HDL-C) metabolism,but the association of endothelial lipase gene (LIPG) polymorphism and serum HDL-C levels is scarce and conflicting in diverse populations.Bai Ku Yao is an isolated subgroup of the Yao minority in China.This study was designed to detect the association of LIPG 584C】T(rs2000813) polymorphism and several environmental factors with serum lipid levels in the Guangxi Bai Ku Yao and Han populations. Methods A total of 645 subjects of Bai Ku Yao and 638 participants of Han Chinese were randomly selected from our previous stratified randomized cluster samples.Genotyping of the LIPG584C】T was performed by polymerse 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),HDL-C, low-density lipoprotein cholesterol(LDL-C) and 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 73.5%and 26.5%in Bai Ku Yao,and 67.9%and 32.1%in Han(P【0.01).The frequency of CC,CT and TT genotypes was 50.4%,46.2%and 3.4%in Bai Ku Yao,and 41.4%, 53.1%and 5.5%in Han(P【0.01);respectively.Serum HDL-C levels in both ethnic groups were different among the three genotypes(P【0.05 for each).Serum TC levels in both ethnic groups were also different between CC and CT/TT types(P【 0.05 for each).The T allele carriers had higher serum HDL-C and TC levels than the T allele noncarriers.Multivariate logistic regression analysis showed that the levels of HDL-C and ApoB were correlated with genotype in Bai Ku Yao(P【 0.05 for each),whereas the levels of TC and HDL-C were associated with genotype in Han Chinese(P【0.05 and P【 0.01).Serum lipid parameters were also correlated with gender, age,weight,body massindex,alcohol consumption, cigarette smoking,and blood pressure in the both ethnic groups.Conclusions The frequency of LIPG 584Tallele is lower in the Bai Ku Yao than in the Han populations.The LIPG 584Tallele is associated with serum HDL-C and TC levels.The differences in serum lipid profiles between the two ethnic groups might partly result from different genotypic and allelic of LIPG 584C 】T or different LIPG-enviromental interactions.

Results The levels of total cholesterol,triglyceride, low-density lipoprotein cholesterol and ApoB in Mu Lao Zu were significantly higher than those in Han(P【0.05-0.001); but the levels of high-density lipoprotein cholesterol,ApoA1 and ApoA1/Apo were significantly lower than those in Han (P【0.001 ).The prevalence of hyperlipidemia and Hypercholesterolemia was also significantly higher in Mu Lao Zu than in Han(53.0%vs.46.1%,P【0.001) and(44.5%vs. 37.5%,P【0.001).There was no difference in the prevalence of hypertriglyceridemia between the both ethnic groups (22.8%vs.19.4%,P】0.05).Hyperlipidemia was positively correlated with age,BMI,and systolic blood pressureMu Lao Zu(P【0.05),whereas it was positively correlated with BMI and hypertension in Han(P【0.05 for each).Conclusions The serum lipid profiles,the prevalence of hyperlipidemia and the risk factors are different between the Mu Lao Zu and Han populations.The differences in serum lipid profiles between the two ethnic groups might result from different dietary habit,life style,as well as genetic factors,in ? To determine the serum lipid levels and their risk factors in the Guangxi.
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Objectives To detect the serum lipid levels and the prevalence of hyperlipidemia in the Jing Zu population. Methods A total of 422 subjects of Jing Zu were studied by a stratified randomized sampling.Serum lipid levels were measured.The data were compared with those in 425 subjects of Han Chinese from the same area.Results triglyceride (TG)were lower in Jing Zu than in Han Chinese [(5.17±0.98) mmol/L vs.(5.37±1.11)mmol/L vs.(1.57±1.80) mmol/L,P【0.05;respectively].There were no significant differences in the levels of high-density lipoprotein cholesterol(HDL-C) and low-density lipoprotein cholesterol (LDL-C) between the two ethnic groups(P】0.05).The prevalence of hypertriglyceridemia and hyperlipidemia was also lower in Jing Zu than in Han Chinese(10.66%vs.15.76%, P【0.05 and 49.76%TG and HDL-C and the prevalence of hypercholesterolemia and hypertriglyceridemia in both ethnic groups were higher in hypertensives than in normotensives. Conclusions The differences in the serum lipid levels and the prevalence of hyperlipidemia between the Jing Zu and Han populations might result from different dietary habit,life style,as well as genetic factors vs.56.94%,P【0.05;respectively). There was no significant difference in the prevalence of hypercholesterolemia between the two ethnic groups.
文摘Objective: To analyze the accuracy of serum prealbumin levels in predicting the prognosis of patients with critical respiratory illness. Methods: Fifty patients with critical respiratory illness admitted to our hospital from October 2022 to September 2023 were selected and divided into an observation group and a control group after condition assessment, with 25 cases in each group. The results of cholinesterase (ChE), prealbumin (PALB), albumin (ALB), aspartate aminotransferase (AST), total protein (TP), and forced expiratory volume (FEV1)/Predicted (Pred) of the two groups were measured. Results: The ChE levels of the observation group were lower than those of the control group, while the PALB and ALB levels of the observation group were higher than those of the control group (P < 0.05). The AST, TP, and FEV1 /Pred levels of the observation group were higher than those in the control group (P < 0.05). Conclusion: Serum PALB levels can be used as the main indicator for prognosis in critically ill respiratory patients.
文摘Background: The etiology of ovarian cancer is not well-understood;numerous metabolomics profiling, epidemiological, and hospital-based case control studies have associated abnormal levels of blood glucose and serum lipids with the risk and the prognosis of various types of cancers including ovarian cancer. The association between the risk of the incidence of ovarian cancer and the alterations in the levels of blood glucose and serum lipids is not well defined. Objective: In this study we aimed to compare the levels of blood glucose, triacylglycerols, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol in patients with different stages of ovarian cancer and healthy controls to determine how they relate to the risk and prognosis of ovarian cancer. Methodology: In a case-control cross sectional study, we enrolled ninety-nine Sudanese women, diagnosed with ovarian cancer but had not received any kind of treatment as the study group, and a control group of forty-one age-matched, apparently healthy women. The patients were classified according to the International Federation of Obstetricians and Gynecologists staging system into two groups: early stages (stage I & II) and late stages (stages III & IV). Blood glucose and serum lipids;triacylglycerols, total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol were determined by enzymatic colorimetric methods using commercially available analytical kits. The IBM SPSS version 20 software was used for statistical analysis. A Mann-Whitney U test was used for comparison of the median concentrations of blood glucose, triacylglycerols, total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol in the study groups. Logistic regression model was used to estimate the relative risk of ovarian cancer in relation to levels of blood glucose and serum lipids. P value of 0.05 was considered significant. Results: Our data indicated significantly higher levels of blood glucose (p < 0.001), triacylglycerols (p = 0.002), and low-density lipoprotein cholesterol (p < 0.001), and lower levels of high-density lipoprotein cholesterol (p = 0.023), in ovarian cancer patients compared to the control subjects. No significant difference was found in the levels of blood glucose or any of the serum lipids between patients in the early stages (stage I & II) and those in late stages (stage III & IV) of ovarian cancer. The logistic regression analysis indicated significant association between the elevated levels of the blood glucose, triacylglycerols and low-density lipoprotein cholesterol and the risk of the ovarian cancer. Conclusion: We conclude that the levels of blood glucose, triacylglycerols, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol differ significantly between ovarian cancer patients and the healthy control subjects. The risk of ovarian cancer was positively associated with the levels of blood glucose, triacylglycerols and low-density lipoprotein cholesterol, and negatively associated with levels of high-density lipoprotein cholesterol. Therefore, determination of blood glucose and serum lipids, particularly, triacylglycerols, low-density lipoprotein cholesterol may be helpful as diagnostic indicators of ovarian cancer (OC).
文摘Background: Diabetes mellitus (DM) is a chronic metabolic disorder characterized by hyperglycemia. DM-related dyslipidemia are associated with complications resulting from progressive damage of various organs. CD36 is 88-kD, class B scavenger receptor, expressed on different types of cells. In diabetic patients, LDL particles are glycated with strong level;this increases CD36 expression, initiates foam cell formation and accelerates atherosclerosis. Objective: This study aimed to determine the correlation between serum CD36 level and lipid profile among patients with type 2 diabetes mellitus in Zeenam Specialized center, Khartoum State, Sudan, in a period between 2019 and 2022. Methodology: Hundred participants at different ages were included in this study;70 were type 2 diabetic patients (cases) and 30 apparently healthy individual (control). 3 ml of venous blood were collected from the participants by using a sterile needle and syringe into a labeled plain container. Each sample was stood until complete clot occurs. Clotted blood sample was then centrifuged to obtain the serum. Then they were used for measurement of total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride and soluble CD36 levels. Total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides were measured using Biosystem chemistry analyzer BTS-302. Serum CD36 was measured using Microplate Reader (URIT-660). Results: The results revealed that serum total cholesterol, LDL cholesterol, HDL cholesterol, and triglyceride levels were significantly higher in patients with type 2 diabetes mellitus compared with control (P = 0.03, P = 0.031, P = 0.000, P = 0.000) respectively, while there is no statistically significant differences in serum CD36 level between cases and control (P = 0.129). Also this study showed that there is no statistically significant correlation between serum CD36 level and total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, age and body mass index. Conclusion: This study concluded that there is no statistically significant difference in serum CD36 level between cases and control. And sCD36 level was not correlated with total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, body mass index, and age.
文摘AIM:To investigate the correlations between lipid metabolism disorder and the occurrence and development of colorectal cancer by monitoring the alterations in lipid levels in cancerous tissue and serum in patients with colorectal cancer.METHODS:The levels of total and free cholesterol(TCH and FCH),triglycerides(TG),low density lipoprotein-cholesterol(LDL-C),high density lipoprotein-cholesterol(HDL-C),apolipoprotein A1(ApoA-1)and ApoB in serum of 206 patients with colorectal cancer,70patients with benign colorectal disease and 300 healthy participants,and in the cancerous tissue and paracancerous tissue of 152 patients with colorectal cancer were measured with an Olympus 600 auto-biochemical analyzer.The obtained data were statistically analyzed.RESULTS:Serum FCH level was significantly higher(1.9±0.4 mmol/L vs 1.3±0.3 mmol/L,1.9±0.4 mmol/L vs 1.2±0.4 mmol/L,P<0.05),whereas serum levels of TCH,LDL-C,ApoA-I and ApoB were significantly lower in patients with colorectal cancer than in patients with benign colorectal disease and healthy controls.The levels of FCH and TG in cancerous tissue were significantly lower(14.5±9.6μmol/g vs 19.3±13.9μmol/g,P<0.05;16.3±19.8μmol/g vs 44.1±38.1μmol/g,P<0.05),whereas HDL-C level was significantly higher(7.9±4.5μmol/g vs 5.7±3.9μmol/g,P<0.01)in cancerous tissue than in paracancerous tissue.The levels of TCH and TG in serum and the levels of TCH and HDL-C in cancerous tissue in patients with colorectal cancer were significantly correlated with TNM stage.The levels of TCH and LDL-C in serum were significantly lower,whereas HDL-C level in cancerous tissue was significantly higher in patients with lymph node metastasis than in patients without lymph node metastasis.The levels of TCH,FCH,TG,HDL-C and LDL-C in cancerous tissue were not significantly different from those in paracancerous tissue.The serum levels of FCH and TG were significantly higher,whereas serum HDL-C levels were significantly lower in patients with rectum cancer than in patients with colon cancer.CONCLUSION:The disordered and abnormally altered levels of lipids in cancerous tissue and serum of patients with colorectal cancer may be correlated with the occurrence and development of colorectal cancer.

文摘Objective To study the effect of oral vitamin D(VD) supplementation on VD status and serum lipid in Chinese obese and healthy normal-weightmen.Methods Twenty-one obese men with their body mass index(BMI)>28 kg/m2served as an obese group and 22 healthy normal-weight men with their BMI<24 kg/m2served as a control group in this study.After they were given 50 000 IU of oral VD,once a week for 8 weeks,the serum25-hydroxyvitamin D [25(OH)D] concentration was measured with an enzyme-immunoassay kit.Results After oral VD supplementation,the serum 25(OH)D concentration significantly increased from46.1±9.1 nmol/L to 116.7±20.3 nmol/L in the obese subjects(P<0.01) and from 52.8±17.8 nmol/L to181.3±30.2 nmol/L in the control ones(P=0.13).The serum high-density lipoprotein cholesterol(HDL-C)level was reduced within the normal reference range in the obese group.However,no significant change was observed in the level of other serum lipids(triglycerides,total cholesterol,and low-density lipoprotein cholesterol) in either of the two groups.Conclusion The effect of high-dose oral VD supplementation is weaker on VD status in the obese group than in the control group.High-dose oral VD supplementation has no side effect on serum lipid level in obese and control groups.
文摘Background: Information on the relationship between height and changes in serum lipids in children is scarce in Cameroon. The aim of this study is to determine prevalence of dyslipidemia with respect to age and gender and assess the association between height increase and serum lipid changes in Cameroon children. Methods: This hospital-based cross-sectional analysis included 472 boys and 534 girls between the ages of 5 and 16 years. Body height, weight, and waist circumference (WC) of children were measured and z-scores calculated. Total cholesterol-TC, triglycerides-TG, low density lipoprotein cholesterol-LDL-C and high-density lipoprotein cholesterol-HDL-C concentrations in fasting blood samples were determined by enzymatic method using an automated clinical chemistry analyzer (RX Monaco, UK). Children were divided into increasing quartiles of height z-score. Multiple linear regression analysis was used to compare mean lipid concentrations across quartiles of height z-score after controlling for age, gender, body weight, WC and fasting blood glucose. Results: The prevalence of elevated TC and LDL-C were respectively 18.5% and 19.2% higher in girls than boys. Also, the prevalence of elevated TC and TG was highest among younger (5- to 9-year-old) girls and boys respectively. There was a significant decrease in mean TC (168.8 to 127.2 mg/dl;p p = 0.019) and LDL-C (91.1 to 69.4 mg/dl;p = 0.018) in boys;and a significant decrease in mean TC (171.2 to 144.7 mg/dl;p = 0.004) and HDL-C (62.8 to 28.7 mg/dl;p p = 0.053) and the decrease in TG (p = 0.211) and LDL-C (p = 0.732) in girls with increasing height were not significant. Conclusion: Serum lipids decreased with increasing height after controlling for different variables. This study indicates that short children have higher serum lipid concentrations and this may increase the risk of lipid disorders, which may persist into adulthood.
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Pneumoconiosis is a systemic occupational disease that commonly manifests as diffuse fibrosis of the lungs caused by long-term inhalation of silica dust in the production process. The development of pneumoconiosis is a chronic and progressive process;once it occurs, it is irreversible, and gradually develops into lung injury and respiratory failure, and can cause death regardless of exposure to dust. The incidence of pneumoconiosis is the highest in China and the direct and indirect economic loss as a result of pneumoconiosis is approximately 9 billion yuan per year.
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.
