METHODS: Female rats(n = 23) were randomly divided into(1) non-pregnant,(contractility, n =6; transit, n = 6); and(2) pregnant(contractility, n = 5; transit, n = 6). In each estrous cycle phase or at 0, 7, 14, and 20 d after the confirmation of pregnancy, gastrointestinal transit was recorded by AC biosusceptometry(ACB), and gastric contractility was recorded by ACB and electromyography. After each recording, blood samples were obtained for progesterone and estradiol determination. RESULTS: In the estrous cycle, despite fluctuations of sex hormone levels, no significant changes in gastrointestinal motility were observed. Days 7 and 14 of pregnancy were characterized by significant changes in the frequency of contractions(3.90 ± 0.42 cpm and 3.60 ± 0.36 cpm vs 4.33 ± 0.25 cpm) and gastric emptying(168 ± 17 min and 165 ± 15 min vs 113 ± 15 min) compared with day 0. On these same days, progesterone levels significantly increased compared with control(54.23 ± 15.14 ng/m L and 129.96 ± 30.52 ng/mL vs 13.25 ± 6.31 ng/mL). On day 14, we observed the highest level of progesterone and the lowest level of estradiol compared with day 0(44.3 ± 15.18 pg/mL vs 24.96 ± 5.96 pg/mL). CONCLUSION: Gastrointestinal motility was unaffected by the estrous cycle. In our data, high progesterone and low estradiol levels can be associated with decreased contraction frequency and slow gastric emptying.展开更多

It is currently involved in the appearance and worsening of several non-transmissible pathologies, making it an environmental, health, and societal problem. The objective of this work was to evaluate the effects of short-term exposure to air pollution on the level of sex hormones in mechanics. We conducted a cross-sectional, analytical, prospective case-control study in Brazzaville on 228 patients (76 cases and 152 controls) from June 2020 to December 2022, a period of 30 months. This study made it possible to evaluate, on the one hand, the level of sexual hormones in men exposed to automobile pollution according to the automated method (ELFA) on mini vidas and, on the other hand, the quality of the air by a colorimetric, punctual method on a Dräger tube coupled with a Dräger accuro pump. The results obtained made it possible to establish a statistically significant link between automobile pollutants (CO, CO<sub>2</sub>, NO<sub>2</sub>, SO<sub>2</sub>) and the increase in LH and FSH on the one hand and the decrease in testosterone on the other hand. We also noted that the concentrations of automotive pollutants during this study were all above the standards required by the WHO. Exposure to automobile pollutants affects the hypothalamic-pituitary axis and therefore disrupts the level of sex hormones.展开更多

Methods: The study was conducted from June 2021 to June 2022. Sixty infertile couples who received IVF cycle treatment in our hospital during this period were selected as the observation group, and 60 couples with good sperm quality and follicle number ≥ 5 who conceived naturally after gynecological disease treatment were selected as the control group during the same period. The sperm quality, sex hormones and ovulation of the two groups were observed, and the change of positive rate was detected by the combined detection method. Results: Compared with the control group, the observation group had less semen (2.82 ± 0.12) ml, lower concentration (69.17 ± 1.28) × 106/ml, normal sperm morphology rate (2.92% ± 0.11%), lower survival rate (70.25% ± 1.16%), higher deformed sperm index (1.39 ± 0.11), and significant differences between groups (P < 0.05);The levels of FSH (7.15 ± 1.33) U/L, LH (5.13 ± 0.53) mU/ml, E2 (72.34 ± 5.11) ng/L, AMH (3.87 ± 0.67) ng/ml and AFC (7.15 ± 0.76) in the control group were significantly better than those in the observation group (P < 0.05). Compared with the single detection method of the three groups, the positive detection rate of the combined diagnosis method was higher, and the difference between the groups was significant (P < 0.05). Conclusion: For the diagnosis of infertility, the combined detection method of sperm quality, sex hormone and ovulation can effectively clarify the problems existing in the couple, significantly improve the detection rate of the cause of the patient, and is more conducive to guiding clinical symptomatic treatment, which is worthy of promotion and reference.展开更多

Kidney asthenia lasting for a long time will result in blood stasis. Also, the cause of VD may have relationships with endothelin (ET), nitric oxide (NO), homocysteine (HCY), estrogen (E2), and testosterone (T). OBJECTIVE: To observed clinical curative effect of the kidney tonic, pancreas tonic, and blood tonic with promoting blood circulation components in treating kidney asthenia with blood stasis syndrome of VD. DESIGN: Case controlled study. SETTING: Geriatric Institute of Integrated Medicine, Fujian College of Traditional Chinese Medicine. PARTICIPANTS: A total of 70 patients, including 39 males and 31 females aged 60-80 years, were selected from Department of Neurology, Pingshan Hospital from May 2000 to September 2002. Diagnostic criteria were used for probable VD of the American Psychiatric Association. Diagnostic and Statistical of Manual of Mental Disorder, 4th ed (DSM-Ⅳ), 1994 revised, mini-mental state examination (MMSE), and criteria of kidney asthenia with blood stasis with mixed weak and sthenia syndrome of Guidelines of Clinical Research of New Chinese Medicine in Treating Dementia. According to score of kidney asthenia with blood stasis syndrome, they were classified to three groups: mild (n =22), moderate (n =33) and severe (n =15). All of them with complete chest X-Ray, ECG, blood chemistry and other related examinations, exclusive of cardiovascular, liver, kidney diseases, homeopathy and psychiatry diseases. And hereby we also select 30 normal people as the comparing group, having no substantial diseases in heart, brain, kidney, liver, lung and other main organic systems after medical examination. Of this group, 11 were males and 19 were females, ranging from 62 years old to 78 years old. There were no obvious differences between the above two groups in sex, age, and education level after statistical analysis. All patients observed in Pingxi Hospital, Fuzhou, from May 2000 to September 2002. METHODS: ① According to the diagnoses standard of blood stasis syndrome: 0-89: The increase in score indicated that blood stasis syndrome was getting serious. ② According to MMSE: All the test samples were evaluated, those with scores of 0-30, in which the non-educated ≤ 17, primary school ≤ 20, above middle school ≤ 24 were categorized. ③ Testing all sample's ET, E2 and T by using radioimmunoassay, the RIA kits were provided by Scientific and Technological Development Center of General Hospital of PLA. ④ Testing the level of NO by using colorimetic method. ⑤ Testing the level of HCY by using Enzyme-linked Immunoassay. ⑥ Meanwhile, analyzing the blood stasis score by comparing with every standard. The differences of data were compared by using t test and F test. MAIN OUTCOME MEASURES: ① Blood plasma ET, blood serum NO, HCY, E2 and T. ② The analyzing results obtained from comparing score of blood stasis with every indicators. RESULTS: The result analysis was including of both the 70 patients of VD with kidney asthenia and blood stasis and compared group consist of 30 healthy people. ① ET, NO, HCY and ET/NO: The levels of ET, HCY and ET/NO were increasing with pathography, while the levels of ET, NO, HCY and ET/NO were decreasing with the pathography, and the difference in statistics was significant (P < 0.01). ② The level of E2 and T: The levels of both E2, T and E2/T for male VD patients were (67.72±12.18) pg/L and (351.58±155.02) ng/L, 0.24±0.12 respectively, which were higher than the compared group [(53.96±16.13) pg/L, (471.83±143.99) ng/L, 0.12±0.00, P < 0.05]. The level of E2 in the female VD patients was lower than the compared group [(34.23±10.99), (44.81±14.65) pg/L, P < 0.05]. ③ The relationship between the score of blood stasis and each indicators: The levels of ET, ET/NO and HCY had significant positive relationship with blood stasis mark (r = 0.352, 0.754, 0.347, P < 0.05-0.01), obvious negative relationship with NO (r =-0.528, P < 0.01) and no clear relationship with female E2/T and male E2/T (r = -0.210, 0.04, P > 0.05). CONCLUSION: ① The levels of ET, HCY and ET/NO are increasing with pathography, while the level of NO is decreasing, which may be the evidence that the possibility of VD pathography may have relationship with the indicators above. ② The level of E2 increase in male's VD patients, and decrease in male's. And the decrease of the female may have relationship with the VD.展开更多

Methodology: BC patients without treatment or use of hormone replacement therapy, or hormonal birth control, and without data of metastasis were included. CG was matched for age, BMI, and menstrual cycle status. FSH, LH, E<sup>2</sup>, progesterone, testosterone, and prolactin (PRL) were measured using radioimmunoassay kits. Comparisons between BC and CG were made with “t” tests, and with the Mann-Whitney U-test;χ<sup>2</sup> test was used to compare the qualitative variables between the groups. Results: Seventy-two patients with BC, and 74 CG women were evaluated. Both groups presented overweight data, BMI (kg/mt<sup>2</sup>) = 27.21 ± 5.51 vs. 28.40 ± 4.66, p = ns, for BC patients and CG, respectively. In PREW, the age at menarche was later in BC patients compared to the CG (13.3 ± 1.36 years vs. 12.41 ± 1.27 years, p = 0.005). The PMW with BC presented a higher age at menarche and menopause compared to the women of the CG (13.51 ± 1.48 vs. 12.91 ± 1.41, p = 0.09, and 49.03 ± 2.86 vs. 45.5 ± 8.78, p = 0.03, respectively). PRL levels were significantly higher in PMW with BC, in comparison with the CG;median and minimum and maximum values (min-max) were: 14.7 ng/mL (3.6 - 52.7) vs. 5.9 ng/mL (1.9 - 33.3), p = 0.005). A higher percentage of PMW with BC (26.0% vs. 7.1%, χ<sup>2</sup> = 5.57, p = 0.01) presented hyperprolactinemia (PRL serum levels > 20 ng/mL), compared to the GC. Conclusions: The higher levels of PRL in PMW with BC compared with CG, suggest a proliferative effect of this hormone in the affected breast tissue. This study demonstrates the need to use biological markers such as PRL to determine the risk of BC in PMW.展开更多

The role of leptin involves different subsets of the immune system. Low levels of serum leptin concentrations are associated with bacterial infections and produce susceptibility to allergic diseases and type Th2 autoimmune diseases. High levels of leptin are associated with Th1 autoimmune diseases via inflammatory responses. Leptin resistance, that happens in obesity, is characterized by the presence of high levels of serum leptin itself accompanied by a clinical situation of a Th2 response. There is a relationship between obesity, leptin resistance, altered immunity and sex hormones. Serum leptin concentration (Th1 response) in women is higher than in men maybe to achieve the balance Th1/Th2 because of the high level of estrogenic hormones (Th2 response) in women.展开更多

文摘AIM: To correlate gastric contractility, gastrointestinal transit, and hormone levels in non-pregnant(estrous cycle) and pregnant rats using noninvasive techniques. METHODS: Female rats(n = 23) were randomly divided into(1) non-pregnant,(contractility, n =6; transit, n = 6); and(2) pregnant(contractility, n = 5; transit, n = 6). In each estrous cycle phase or at 0, 7, 14, and 20 d after the confirmation of pregnancy, gastrointestinal transit was recorded by AC biosusceptometry(ACB), and gastric contractility was recorded by ACB and electromyography. After each recording, blood samples were obtained for progesterone and estradiol determination. RESULTS: In the estrous cycle, despite fluctuations of sex hormone levels, no significant changes in gastrointestinal motility were observed. Days 7 and 14 of pregnancy were characterized by significant changes in the frequency of contractions(3.90 ± 0.42 cpm and 3.60 ± 0.36 cpm vs 4.33 ± 0.25 cpm) and gastric emptying(168 ± 17 min and 165 ± 15 min vs 113 ± 15 min) compared with day 0. On these same days, progesterone levels significantly increased compared with control(54.23 ± 15.14 ng/m L and 129.96 ± 30.52 ng/mL vs 13.25 ± 6.31 ng/mL). On day 14, we observed the highest level of progesterone and the lowest level of estradiol compared with day 0(44.3 ± 15.18 pg/mL vs 24.96 ± 5.96 pg/mL). CONCLUSION: Gastrointestinal motility was unaffected by the estrous cycle. In our data, high progesterone and low estradiol levels can be associated with decreased contraction frequency and slow gastric emptying.

文摘Background Sex hormones play important roles in the estrus return of post-weaning sows.Previous studies have demonstrated a complex and bi-directional regulation between sex hormones and gut microbiota.However,the extent to which the gut microbiota affects estrus return of post-weaning sows is largely unknown.Results In this study,we first screened 207 fecal samples from well-phenotyped sows by 16S rRNA gene sequencing and identified significant associations between microbes and estrus return of post-weaning sows.Using metagenomic sequencing data from 85 fecal samples,we identified 37 bacterial species that were significantly associated with estrus return.Normally returning sows were characterized by increased abundances of L.reuteri and P.copri and decreased abundances of B.fragilis,S.suis,and B.pseudolongum.The changes in gut microbial composition significantly altered the functional capacity of steroid hormone biosynthesis in the gut microbiome.The results were confirmed in a validation cohort.Significant changes in sex steroid hormones and related compounds were found between normal and non-return sows via metabolome analysis.An integrated analysis of differential bacterial species,metagenome,and fecal metabolome provided evidence that normal return-associated bacterial species L.reuteri and Prevotella spp.participated in the degradation of pregnenolone,progesterone,and testosterone,thereby promoting estrogen biosynthesis.Furthermore,the microbial metabolites related to sow energy and nutrient supply or metabolic disorders also showed relationships with sow estrus return.Conclusions An integrated analysis of differentially abundant bacterial species,metagenome,and fecal metabolome revealed the involvement of L.reuteri and Prevotella spp.in sow estrus return.These findings provide deep insight into the role of gut microbiota in the estrus return of post-weaning sows and the complex cross-talk between gut microbiota and sex hormones,suggesting that the manipulation of the gut microbiota could be an effective strategy to improve sow estrus return after weaning.

文摘The occurrence of benign prostate hyperplasia(BPH)was related to disrupted sex steroid hormones,and metformin(Met)had a clinical response to sex steroid hormone-related gynaecological disease.However,whether Met exerts an antiproliferative effect on BPH via sex steroid hormones remains unclear.Here,our clinical study showed that along with prostatic epithelial cell(PEC)proliferation,sex steroid hormones were dysregulated in the serum and prostate of BPH patients.As the major contributor to dysregulated sex steroid hormones,elevated dihydrotestosterone(DHT)had a significant positive relationship with the clinical characteristics of BPH patients.Activation of adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK)by Met restored dysregulated sex steroid hormone homeostasis and exerted antiproliferative effects against DHT-induced proliferation by inhibiting the formation of androgen receptor(AR)-mediated Yes-associated protein(YAP1)-TEA domain transcription factor(TEAD4)heterodimers.Met’s anti-proliferative effects were blocked by AMPK inhibitor or YAP1 overexpression in DHT-cultured BPH-1 cells.Our findings indicated that Met would be a promising clinical therapeutic approach for BPH by inhibiting dysregulated steroid hormone-induced PEC proliferation.
文摘Objective:To analyze the effect of thyroid-stimulating hormone(TSH)suppression therapy on sex hormone levels in patients undergoing postoperative treatment for thyroid cancer.Methods:A total of 40 patients undergoing postoperative thyroid cancer treatment were selected for data analysis.TSH suppression therapy was implemented during the postoperative period.Patients were grouped according to the TSH level:TSH<0.1,0.1≤TSH<0.5,and TSH≥0.5.Results:Among male patients,there were no significant differences in sex hormone levels at different dosing times and TSH levels(P>0.05).For female patients,testosterone levels at different dosing times showed no significant differences under the same circumstances(P>0.05).The comparison of testosterone levels at different TSH levels over 5 years of TSH suppression therapy did not yield significant differences(P>0.05).However,the comparison of testosterone levels within 5 years of TSH suppression therapy yielded significant differences(P<0.05),with the lowest levels observed at 0.1≤TSH<0.5.Conclusion:The use of TSH suppression therapy in postoperative thyroid cancer treatment minimally affects sex hormone levels in male patients.However,it has a significant impact on female patients.Therefore,preoperative sex hormone testing is recommended,and postoperative monitoring should include regular sex hormone testing.
文摘Air pollution is today a real concern across the world, responsible for around 7 million deaths per year around the world. It is currently involved in the appearance and worsening of several non-transmissible pathologies, making it an environmental, health, and societal problem. The objective of this work was to evaluate the effects of short-term exposure to air pollution on the level of sex hormones in mechanics. We conducted a cross-sectional, analytical, prospective case-control study in Brazzaville on 228 patients (76 cases and 152 controls) from June 2020 to December 2022, a period of 30 months. This study made it possible to evaluate, on the one hand, the level of sexual hormones in men exposed to automobile pollution according to the automated method (ELFA) on mini vidas and, on the other hand, the quality of the air by a colorimetric, punctual method on a Dräger tube coupled with a Dräger accuro pump. The results obtained made it possible to establish a statistically significant link between automobile pollutants (CO, CO<sub>2</sub>, NO<sub>2</sub>, SO<sub>2</sub>) and the increase in LH and FSH on the one hand and the decrease in testosterone on the other hand. We also noted that the concentrations of automotive pollutants during this study were all above the standards required by the WHO. Exposure to automobile pollutants affects the hypothalamic-pituitary axis and therefore disrupts the level of sex hormones.
文摘Coronavirus disease-2019(COVID-19),a respiratory tract infection caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has become a global health emergency and a threat the entire world.The COVID-19 shows a wide spectrum of clinical presentations,severity,and fatality rates.Although the fatal outcomes of the COVID-19 pandemic are evident in all age groups,the most devastating impact on the health consequences and death from COVID-19 are associated with older adults,especially older men.COVID-19 pandemic is affecting different countries in the world especially in the 65+years age male group.In fact,several genes involved into the regulation of the immune system are strategically placed on the X-chromosome and trigger a gendered mediated antiviral fight.The aim of this study is to explore and exploit whether a relationship exists between male sex and COVID-19 mortality and the relationship is age dependent.Herein we discuss the possible role of physiological and immunological sex differences into the higher morbidity and mortality of SARSCoV-2 between females and males.Deciphering gender differences in COVID-19 offers a window into the principles of immunity against SARS-CoV-2 infection and this information on ageing dependent gender disparity might contribute to our current understanding of COVID-19 infection and disease treatment.
文摘Objective: To analyze the application value of combined detection of sperm quality, sex hormone and ovulation in the diagnosis of infertility. Methods: The study was conducted from June 2021 to June 2022. Sixty infertile couples who received IVF cycle treatment in our hospital during this period were selected as the observation group, and 60 couples with good sperm quality and follicle number ≥ 5 who conceived naturally after gynecological disease treatment were selected as the control group during the same period. The sperm quality, sex hormones and ovulation of the two groups were observed, and the change of positive rate was detected by the combined detection method. Results: Compared with the control group, the observation group had less semen (2.82 ± 0.12) ml, lower concentration (69.17 ± 1.28) × 106/ml, normal sperm morphology rate (2.92% ± 0.11%), lower survival rate (70.25% ± 1.16%), higher deformed sperm index (1.39 ± 0.11), and significant differences between groups (P < 0.05);The levels of FSH (7.15 ± 1.33) U/L, LH (5.13 ± 0.53) mU/ml, E2 (72.34 ± 5.11) ng/L, AMH (3.87 ± 0.67) ng/ml and AFC (7.15 ± 0.76) in the control group were significantly better than those in the observation group (P < 0.05). Compared with the single detection method of the three groups, the positive detection rate of the combined diagnosis method was higher, and the difference between the groups was significant (P < 0.05). Conclusion: For the diagnosis of infertility, the combined detection method of sperm quality, sex hormone and ovulation can effectively clarify the problems existing in the couple, significantly improve the detection rate of the cause of the patient, and is more conducive to guiding clinical symptomatic treatment, which is worthy of promotion and reference.
文摘In the recent decades,obesity rates among children and adolescents,especially males,have increased significantly.This worldwide phenomenon is thought to significantly affect the levels of sex hormones.However,the association between waist circumference(a marker of abdominal obesity)and sex hormone levels in children and adolescents is unknown.In this study,4031 participants aged 6–19 years from the United States National Health and Nutrition Examination Survey(NHANES)in the USA were enrolled in this study.The common confounders of age,race,body mass index,educational level,family income,diabetes,and time of sample collection were also collected.The participants missing any of the above information were excluded from the study.We used multiple linear regression and other multiple statistics to assess the associations between waist circumference and serum testosterone,estradiol,sex hormone-binding globulin(SHBG),free androgen index(FAI),and testosterone/estradiol ratio(T/E2).Waist circumference remained associated with sex hormone levels in children and adolescents after controlling for covariates.As waist circumference increases,testosterone levels in children and adolescents show an overall decline after a brief increase,with the inflection point for waist circumference of 65–66 cm.In addition,waist circumference positively correlates with estradiol levels in male children(β=0.007,95%confidence interval:0.004–0.009).Moreover,circulating SHBG decreases in children and adolescents as waist circumference increases.In conclusion,this study highlighted waist circumference as a vital indicator affecting sex hormone levels in children and adolescents.
文摘BACKGROUND: Kidney asthenia is the basic cause of the development of vascular dementia (VD). Kidney asthenia lasting for a long time will result in blood stasis. Also, the cause of VD may have relationships with endothelin (ET), nitric oxide (NO), homocysteine (HCY), estrogen (E2), and testosterone (T). OBJECTIVE: To observed clinical curative effect of the kidney tonic, pancreas tonic, and blood tonic with promoting blood circulation components in treating kidney asthenia with blood stasis syndrome of VD. DESIGN: Case controlled study. SETTING: Geriatric Institute of Integrated Medicine, Fujian College of Traditional Chinese Medicine. PARTICIPANTS: A total of 70 patients, including 39 males and 31 females aged 60-80 years, were selected from Department of Neurology, Pingshan Hospital from May 2000 to September 2002. Diagnostic criteria were used for probable VD of the American Psychiatric Association. Diagnostic and Statistical of Manual of Mental Disorder, 4th ed (DSM-Ⅳ), 1994 revised, mini-mental state examination (MMSE), and criteria of kidney asthenia with blood stasis with mixed weak and sthenia syndrome of Guidelines of Clinical Research of New Chinese Medicine in Treating Dementia. According to score of kidney asthenia with blood stasis syndrome, they were classified to three groups: mild (n =22), moderate (n =33) and severe (n =15). All of them with complete chest X-Ray, ECG, blood chemistry and other related examinations, exclusive of cardiovascular, liver, kidney diseases, homeopathy and psychiatry diseases. And hereby we also select 30 normal people as the comparing group, having no substantial diseases in heart, brain, kidney, liver, lung and other main organic systems after medical examination. Of this group, 11 were males and 19 were females, ranging from 62 years old to 78 years old. There were no obvious differences between the above two groups in sex, age, and education level after statistical analysis. All patients observed in Pingxi Hospital, Fuzhou, from May 2000 to September 2002. METHODS: ① According to the diagnoses standard of blood stasis syndrome: 0-89: The increase in score indicated that blood stasis syndrome was getting serious. ② According to MMSE: All the test samples were evaluated, those with scores of 0-30, in which the non-educated ≤ 17, primary school ≤ 20, above middle school ≤ 24 were categorized. ③ Testing all sample's ET, E2 and T by using radioimmunoassay, the RIA kits were provided by Scientific and Technological Development Center of General Hospital of PLA. ④ Testing the level of NO by using colorimetic method. ⑤ Testing the level of HCY by using Enzyme-linked Immunoassay. ⑥ Meanwhile, analyzing the blood stasis score by comparing with every standard. The differences of data were compared by using t test and F test. MAIN OUTCOME MEASURES: ① Blood plasma ET, blood serum NO, HCY, E2 and T. ② The analyzing results obtained from comparing score of blood stasis with every indicators. RESULTS: The result analysis was including of both the 70 patients of VD with kidney asthenia and blood stasis and compared group consist of 30 healthy people. ① ET, NO, HCY and ET/NO: The levels of ET, HCY and ET/NO were increasing with pathography, while the levels of ET, NO, HCY and ET/NO were decreasing with the pathography, and the difference in statistics was significant (P < 0.01). ② The level of E2 and T: The levels of both E2, T and E2/T for male VD patients were (67.72±12.18) pg/L and (351.58±155.02) ng/L, 0.24±0.12 respectively, which were higher than the compared group [(53.96±16.13) pg/L, (471.83±143.99) ng/L, 0.12±0.00, P < 0.05]. The level of E2 in the female VD patients was lower than the compared group [(34.23±10.99), (44.81±14.65) pg/L, P < 0.05]. ③ The relationship between the score of blood stasis and each indicators: The levels of ET, ET/NO and HCY had significant positive relationship with blood stasis mark (r = 0.352, 0.754, 0.347, P < 0.05-0.01), obvious negative relationship with NO (r =-0.528, P < 0.01) and no clear relationship with female E2/T and male E2/T (r = -0.210, 0.04, P > 0.05). CONCLUSION: ① The levels of ET, HCY and ET/NO are increasing with pathography, while the level of NO is decreasing, which may be the evidence that the possibility of VD pathography may have relationship with the indicators above. ② The level of E2 increase in male's VD patients, and decrease in male's. And the decrease of the female may have relationship with the VD.

文摘Immunoglobulin G(IgG)is the most abundant plasma glycoprotein and a prominent humoral immune mediator.Glycan composition affects the affinity of IgG to ligands and consequent immune responses.The modification of IgG N-glycosylation is considered to be one of the various mechanisms by which sex hormones modulate the immune system.Although the menstrual cycle is the central sex hormonerelated physiological process in most women of reproductive age,IgG N-glycosylation dynamics during the menstrual cycle have not yet been investigated.To fill this gap,we profiled the plasma IgG Nglycans of 70 healthy premenopausal women at 12 time points during their menstrual cycles(every 7 days for 3 months)using hydrophilic interaction ultra-performance liquid chromatography(HILIC-UPLC).We observed cyclic periodic changes in the N-glycosylation of IgG in association with the menstrual cycle phase and sex hormone concentration in plasma.On the integrated cohort level,the modeled average menstrual cycle effect on the abundance of IgG N-glycosylation traits was low for each trait,with the highest being 1.1%for agalactosylated N-glycans.However,intrapersonal changes were relatively high in some cases;for example,the largest difference between the minimum and maximum values during the menstrual cycle was up to 21%for sialylated N-glycans.Across all measurements,the menstrual cycle phase could explain up to 0.72%of the variation in the abundance of a single IgG glycosylation trait of monogalactosylation.In contrast,up to 99%of the variation in the abundance of digalactosylation could be attributed to interpersonal differences in IgG N-glycosylation.In conclusion,the average extent of changes in the IgG N-glycopattern that occur during the menstrual cycle is small;thus,the IgG N-glycoprofiling of women in large sample-size studies can be performed regardless of menstrual cycle phase.
文摘Objective: The aim of this study was to determine body composition, gynecological, and obstetric data, sex hormones, and prolactin serum levels in pre- (PREW) and postmenopausal women (PMW) with breast cancer (BC) and compare them with a control group (CG) of healthy women. Methodology: BC patients without treatment or use of hormone replacement therapy, or hormonal birth control, and without data of metastasis were included. CG was matched for age, BMI, and menstrual cycle status. FSH, LH, E<sup>2</sup>, progesterone, testosterone, and prolactin (PRL) were measured using radioimmunoassay kits. Comparisons between BC and CG were made with “t” tests, and with the Mann-Whitney U-test;χ<sup>2</sup> test was used to compare the qualitative variables between the groups. Results: Seventy-two patients with BC, and 74 CG women were evaluated. Both groups presented overweight data, BMI (kg/mt<sup>2</sup>) = 27.21 ± 5.51 vs. 28.40 ± 4.66, p = ns, for BC patients and CG, respectively. In PREW, the age at menarche was later in BC patients compared to the CG (13.3 ± 1.36 years vs. 12.41 ± 1.27 years, p = 0.005). The PMW with BC presented a higher age at menarche and menopause compared to the women of the CG (13.51 ± 1.48 vs. 12.91 ± 1.41, p = 0.09, and 49.03 ± 2.86 vs. 45.5 ± 8.78, p = 0.03, respectively). PRL levels were significantly higher in PMW with BC, in comparison with the CG;median and minimum and maximum values (min-max) were: 14.7 ng/mL (3.6 - 52.7) vs. 5.9 ng/mL (1.9 - 33.3), p = 0.005). A higher percentage of PMW with BC (26.0% vs. 7.1%, χ<sup>2</sup> = 5.57, p = 0.01) presented hyperprolactinemia (PRL serum levels > 20 ng/mL), compared to the GC. Conclusions: The higher levels of PRL in PMW with BC compared with CG, suggest a proliferative effect of this hormone in the affected breast tissue. This study demonstrates the need to use biological markers such as PRL to determine the risk of BC in PMW.

文摘The incidence of diabetes and cancer has increased significantly in recent years.Furthermore,there are many common risk factors for both diabetes and cancer,such as obesity,sedentary lifestyle,smoking,and ageing.A large body of epidemiological evidence has indicated that diabetes is considered as an independent risk factor for increased rates of heterogeneous types of cancer occurrence and death.The incidence and mortality of various types of cancer,such as pancreas,liver,colorectal,breast,endometrial,and bladder cancers,have a modest growth in diabetics.However,diabetes may work as a protective factor for prostate cancer.Although the underlying biological mechanisms have not been totally understood,studies have validated that insulin/insulin-like growth factor(IGF)axis(including insulin resistance,hyperinsulinemia,and IGF),hyperglycemia,inflammatory cytokines,and sex hormones provide good circumstances for cancer cell proliferation and metastasis.Insulin/IGF axis activates several metabolic and mitogenic signaling pathways;hyperglycemia provides energy for cancer cell growth;inflammatory cytokines influence cancer cell apoptosis.Thus,these three factors affect all types of cancer,while sex hormones only play important roles in breast cancer,endometrial cancer,and prostate cancer.This minireview consolidates and discusses the epidemiological and biological links between diabetes and various types of cancer.
文摘Adipocytes produce hormones and adipokines, among others leptin, with metabolic and inflammatory responses. The role of leptin involves different subsets of the immune system. Low levels of serum leptin concentrations are associated with bacterial infections and produce susceptibility to allergic diseases and type Th2 autoimmune diseases. High levels of leptin are associated with Th1 autoimmune diseases via inflammatory responses. Leptin resistance, that happens in obesity, is characterized by the presence of high levels of serum leptin itself accompanied by a clinical situation of a Th2 response. There is a relationship between obesity, leptin resistance, altered immunity and sex hormones. Serum leptin concentration (Th1 response) in women is higher than in men maybe to achieve the balance Th1/Th2 because of the high level of estrogenic hormones (Th2 response) in women.
文摘BACKGROUND Improper methods of contraception greatly increase the risk of abortion,cervical or endometrial lesions,and the number of recurrent artificial abortions.These complications result in the deterioration of a patient’s outcome.Further,the proportion of artificial abortions is highest among unmarried females.Placement of an intrauterine device,such as the Mirena,after an artificial abortion may decrease the likelihood of an endometrial injury caused by recurrent abortions while significantly improving its contraceptive effects.AIM To discuss the effect of Mirena placement on reproductive hormone levels at different time points after an artificial abortion.METHODS Women(n=119)undergoing an artificial abortion operation were divided into the study(n=56)and control(n=63)groups.In the study group,the Mirena was inserted immediately after the artificial abortion,whereas in the control group,it was inserted 4–7 d after the onset of the first menstrual cycle after abortion.All participants were followed-up for 6 mo to observe the continuation and expulsion rates and adverse reactions and to measure the levels of serum estradiol(E2),follicle stimulating hormone(FSH),and luteinizing hormone(LH).RESULTS The continuation rates were 94.64%and 93.65%in the study group and the control group,respectively.The expulsion rates were 1.79%and 3.17%in the study group and the control group,respectively.There was no statistically significant difference between the two groups(P>0.05).There were also no statistically significant differences in the proportion of patients with bacterial vaginitis,trichomonas vaginitis,or cervicitis between the groups(P>0.05).Six months after Mirena placement,E2 Levels were 45.50±7.13 pg/mL and 42.91±8.10 pg/mL,FSH 13.60±3.24 mIU/mL and 14.54±3.11 mIU/mL,and LH 15.11±2.08 mIU/mL and 14.60±3.55 mIU/mL in the study and control groups,respectively.There were no significant differences in hormone levels between the two groups(P>0.05).There were also no statistically significant differences in the proportions of abnormal menstruation,prolonged menstruation,or pain during intercourse between the study and control groups after Mirena placement(P>0.05).There were no statistically significant differences in uterine volume,sexual desire,sexual activity,or the sexual satisfaction score between the study and control groups before and after Mirena placement(P>0.05).CONCLUSION Placement of a Mirena intrauterine device immediately after an artificial abortion does not increase the risk of adverse reactions and can help prevent endometrial injury caused by recurrent abortions.

文摘A bacterial strain,ZY3,growing on sex steroid hormones as the sole source of carbon and energy was isolated from the sewage treatment plant of a prophylactic steroids factory.ZY3 degrades the 3-methoxy-17b-hydroxy-1,3,5(10),8(9)-d-4-estren(MHE).This strain was preli-minarily identified as Raoultella sp.ZY3 according to its morphology and its 16S rRNA gene sequence.During the experimental period(72 h),the optimum temperature,pH and 3-MHE concentration for the degradation of hydride by the strain ZY3 were 35°C,10 and 10 mg/L,respectively.The degradation rate of the sex steroid hormones increased to 87%and 85% after the addition of maltose and peptone,respectively.
文摘Objective:To investigate the clinical efficacy of the combination of enhanced“Shou Tai Wan”soup and progesterone in the treatment of early pre-eclampsia miscarriage.Methods:86 patients with early pre-eclampsia miscarriage in our hospital from July 2021 to July 2022 were selected and randomly divided into two groups of 43 cases each.The control group was treated with progesterone,while the study group was treated with an addition of enhanced“Shou Tai Wan”soup.The treatment effects of the two groups and the changes in the inflammatory factor levels and sex hormone levels before and after the treatment were observed.Results:INF-γand Il-2 were lower and IL-4 was higher in the study group than in the control group after treatment(p-value<0.05);the total effective rate of treatment was higher in the study group(95.35%)than in the control group(74.42%),(p-value<0.05);the levels of P,E2 andβ-hCG were higher in the study group than in the control group after treatment(p-value<0.05).Conclusion:The combined application of enhanced“Shou Tai Wan”soup and progesterone in patients with early preterm abortion is more effective by improving the patients’sex hormone levels and reducing the level of inflammatory factors,which is conducive to the improvement of the treatment effect and worthy of promotion.
