The serum level of testosterone (T), estradiol (E2) and progesterone (P) in 86 cases with primary liver cancer (PLC) (male：76 cases; female：10 cases) was determined by RIA method. The result showed that for male cases, serum level of T and ratio of T/E２ in operation group and nonoperation group was significantly higher than that in benign hepatic diseases group (BHD group) and normal control group (NC group), but the value of E２ obviously lower than the later two groups. After tumor resection, the level of E2 increased, while serum level of T and value of T/E２ decreased, which had no significant difference as contrasted with BHD group and NC group. The serum level of T,E2 in female PLC group made no difference to BHD group and NC group, but the value of T/E2 much higher than NC group. No obvious changes of the serum level of progesterone can be observed in both male and female cases. Our research showed that high serum testosterone level and low estradiol level may be concerned with PLC. The possibility and importance of sex hormone imbalance on initializing and developing of PLC is suggested.
ObjectiveTo summarize the relevant studies of pharmacological mechanism of tamoxifen and its influence on ovary function in order to provide information and evidence for the therapy of breast cancer. MethodsPapers published from January 1950 to January 2014, were retrieved in MedLine, OVID, CBM, CNKI databases using the keywords on tamoxifen, drug metabolism, ovary, sex hormone, etc, 1286 papers were retrieved in English literatures, and 621 in Chinese literatures. Criteria of paper adoption:①The clinical and basic studies about metabolism of tamoxifen, metabolic effect of tamoxifen, and gene polymorphism of CYP2D6.②The role played by estrogen receptor and protein cofactors in tamoxifen effect.③The clinical and basic studies about tamoxifen induced ovulation, caused endometrial thickening, changed sex hormone levels. According to the above criteria, 152 papers were selected, and 77 papers out of them were finally analyzed and reviewed. Results①The tamoxifen metabolite 4-OH-N-tamoxifen was the main working component, the decreased levels could predict the poor prognosis.②The CYP2D6 gene polymorphism could affect the metabolic effect of tamoxifen and the therapeutic effect of patients with breast cancer.③The metabolic effect of tamoxifen needed the participation of the estrogen receptors and protein cofactors.④Tamoxifen could affect the reproductive system function through the estrogen receptor of H-P-O axis, ovary, and endometrium. ConclusionsMetabolic effect of tamoxifen is regulated by gene, it could affect reproductive system functions through estrogen receptor. the mechanism that tamoxifen cowld affect the hormone levels and wherther it could reflect the ovarian function by monitering the hormone levels continuously for patients with breast cancer need to be researched.
Objective To ananlyze the relationship between bone mineral density and sex hormone in male patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods The study recruited 88 male patients with OSAHS aged 45-60 years in our hospital from October 2014 to October 2016 as an OSAHS group, and 30 healthy subjects without OSAHS as a control group. The general information and PSG parameters were recorded, the bone metabolic markers and bone mineral density of lumbar spine 1-4 (L1-4) and femoral neck (Neck) were measured, and the expressions of serum sex hormone (E2, P, T, FSH, LH and PRL) were determined by chemical luminescence immunity analyzer. The differences in above indexes between two groups and their correlation with bone mineral density were analyzed. Results Smoking rate, drinking rate, neck circumference and body mass index (BMI) of the OSAHS group were significantly higher than those of the control group. Compared with the control group, beta crosslaps (β-CTX, a bone metabolic marker) was significantly higher [(0.53±0.14) ng/ml vs. (0.47±0.15) ng/ml], the bone mineral density of L1-4 and Neck was significantly lower [(0.92±0.12) g/cm2 vs. (1.08±0.08) g/cm2, (0.91±0.11) g/cm2 vs. (1.06±0.13) g/cm2], and the serum testosterone was significantly lower in the OSAHS group [(267.32±89.56) ng/dlvs. (315.68±78.49) ng/dl] (all P<0.05). The result of Pearson correlation analysis showed that apnea hypopnea index (AHI) was negatively correlated with bone mineral density of L1-4 and Neck (bothP<0.001), lowest oxygen saturation (LSaO2) and testosterone were positively correlated with bone mineral density of L1-4 and Neck (all P<0.01). Conclusions The risk of suffering from osteoporosis is higher in male OSAHS patients and it is closely related to the degree of hypoxia. The decrease of testosterone may be one of the mechanisms.
Objective To investigate the influence of Lamotrigine (LTG) on sex hormone, seminal fluid and sexual function in male epilepsy patients. Methods The blood sex hormone levels and sperm quality were detected in 20 normal controls and 16 male epilepsy patients in Epilepsy Center of Sichuan Province People's Hospital from April 2015 to November 2016. All participants were detected before taking medicine and after being treated with LTG monotherapy for 1 year. The international index of erectile function-5 (IIEF-5) was employed to assess the sexual function in the groups above, and the results were compared. Results Compared with the control group, the total number of sperm, the rate of forward movement, survival, normal sperm and the score of IIEF-5 in the untreated group were less (P<0.05). LTG treatment group's sperm parameters and the score of IIEF-5 seemed improve, but there was no statistically significant difference (P>0.05). There was no significant difference in sexual hormones between the groups above (P>0.05). Conclusions Semen quality and the score of IIEF-5 in epileptic male decline more easily; LTG might improve the semen quality and sexual function, but no significant difference has being found.
The incidence of chronic kidney disease is increasing worldwide, which greatly increases the risk of end-stage renal disease. It is particularly important to find out the risk factors for the development and progression of chronic kidney disease. Whether gender is a risk factor for the progression of kidney disease remains controversial with inconsistent results in human cohort studies with diabetic or non-diabetic kidney disease. In most of the studies, women seem to exhibit certain gender advantages. Sex hormones, renal hemodynamics and lifestyle differences may play an important role. The underlying mechanism of gender affecting the progression of kidney disease deserves further exploration. This article reviews the gender differences and possible mechanisms in diabetic and non-diabetic chronic kidney disease, in order to provide reference for future research.
ObjectiveTo analyse baseline information, semen, sex hormones and sexual function to understand the differences between male patient with epilepsy(MPWE) and healthy men. At the same time, we preliminarily evaluated the risk factors related to reproductive function in MPWE to provide clinical method for reducing the risk of infertility.MethodsWe collected data of 112 MPWE in the Department of Neurology, First Affiliated Hospital of Dali University from February 2019 to February 2020. Sixty-seven healthy male volunteers matching the age of the survey group were selected. All men completed semen and sex hormone test. Men with sexual life experience completed the International index of erectile function scale (IIEF-5) and the Premature ejaculation diagnostic tool (PEDT). MPWE completed the Quality of life in epilepsy-1(QOLIE-31). The baseline data, semen quality, sex hormone level and sexual function questionnaire scores of MPWE and healthy controls were compared. In addition, according to the diagnostic criteria of abnormal male reproductive function, MPWE were divided into abnormal group and normal group. Single factor analysis and binary logistic regression analysis were used to preliminarily explore the related risk factors of reproductive function in MPWE.ResultsCompared with the healthy control group, the proportion of married and childbearing, testosterone level, sperm concentration, sperm survival rate and IIEF-5 score in MPWE were significantly reduced (P<0.05). Compared with the normal group, age, body mass index, seizure frequency and drug type in the abnormal group were significant differences statistically (P<0.05). The total score and energy score of QOLIE-31 in the abnormal group were significantly lower than that in the normal group (P<0.05). Binary Logistic regression analysis indicated that energy score [B=−0.033, OR=0.967, 95%CI(0.937, 0.999)], age [B=0.879, OR=2.408, 95%CI (1.070, 5.416)], seizure frequency [B=1.788, OR=5.976, 95% CI (2.031, 17.589)].ConclusionThe reproductive function of MPWE is lower than that in healthy men. The total score, energy score, age, body mass index, seizure frequency and type of drugs will significantly affect the reproductive function of MPWE. Energy score, age and seizure frequency are independent risk factors that affect the reproductive function of MPWE. Abnormal reproductive function of MPWE was positively correlated with age and seizure frequency, but negatively correlated with energy score.
Objective To examine the influence of hormonal fluctuations on the perioperative outcomes of patients undergoing congenital heart surgery. Methods We conducted a retrospective analysis of clinical data from fertile women diagnosed with congenital heart disease at the Guangdong Provincial People's Hospital, between January 1, 2015, and July 30, 2019. Initially, patients were categorized into groups based on serum progesterone levels: a low progesterone group (n=31) and a high progesterone group (n=153). Furthermore, based on serum estrogen levels, they were divided into a low estrogen group (n=10), a medium estrogen group (n=32), and a high estrogen group (n=118) for comparative analysis. A control group (n=24) consisted of patients who received progesterone injections before their menstrual period. Results We finally included 184 patients. The patients’ average age was 27.6±5.7 years, with 142 (77.17%) presenting with complex congenital heart conditions. There were statistically significant differences in total postoperative standard thoracic drainage volume and postoperative albumin level between the high and low progesterone groups (P<0.05), while other perioperative outcome indicators showed no statistical differences (P>0.05). Among the different serum estrogen level groups, there were statistically significant differences in postoperative blood urea nitrogen levels, total postoperative standard thoracic drainage volume, and hospital stay (P<0.05), while other perioperative outcome indicators showed no statistical differences (P>0.05). ConclusionConsidering the overall clinical significance, the physiological changes in sex hormone levels appear to have a negligible effect on the perioperative outcomes of fertile women with congenital heart disease.
