Research progress on sex hormone-binding globulin involved in the occurrence and development of diabetes mellitus / 中国基层医药

Sex hormone-binding globulin (SHBG) is significantly associated with abnormal glucose metabolism. Low SHBG level is a risk factor for insulin resistance and the occurence of diabetes mellitus. SHBG is negatively correlated with the risk of type 2 diabetes mellitus and plays an important role in regulating insulin resistance while predicting its development. The genotype of SHBG has been found to be closely related to the occurrence of diabetes mellitus. Fatty liver and DNA methylation are also important factors mediating the relationship between SHBG and type 2 diabetes mellitus. The change in SHBG level may be related to insulin resistance by influencing hepatocyte nuclear factor 4a and regulating glucose transporter.

The changes of sex hormone levels in male patients with metabolic syndrome and its clinical significance / 中国基层医药

Objective To investigate the changes of sex hormone levels in male patients with metabolic syndrome and its clinical significance.Methods From January 2012 to January 2016,a total of 186 male patients in the Integrated Chinese and Western Medicine Hospital Affliated to Nanjing University of Traditional Chinese Medicine were enrolled,and they were divided into MS group(n =112) and non-MS group(n =74) according to the definition of adult metabolic syndrome.All of patients were measured blood pressure,blood glucose,blood lipid,pancreas islet function and sex hormone,such as testosterone (TT),sex hormone binding globuli (SHBG),progestin (P),prolactin (PRL),luteinizing hormone (LH),follicle-stimulating hormone (FSH),estradiol (E2),dehydroepiandrosterone (DHEA).The sex hormone level and the correlation of components of metabolic syndrome between the two groups were compared.Results Compared with those in the non-MS group,the BMI,blood pressure,lipid levels in the MS group were significantly increased,the fasting blood glucose,HbA1c,FINS HOMA-IR in the MS group were significantly increased[(8.74 ± 1.93) mmol/L vs.(7.49 ± 2.39) mmol/L,(10.86 ±2.45)％ vs.(9.09 ±2.61)％,(13.62 ± 6.37) mIU/L vs.(6.88 ±5.05)mIU/L,(5.53 ±2.28) vs.(3.24 ±1.35),t=5.76,4.49,2.47,2.81,all P ＜ 0.05],and TT,SHBG in the MS group significantly decreased [(18.95 ± 9.51) nmol/L vs.(10.10 ±2.97)nmol/L,(35.86±27.93)nmol/Lvs.(25.56±19.90)nmol/L,t=3.18,5.46,allP＜0.05].Conclusion MS was associated with hypogonadism,and the more components of metabolic syndrome,the more hypogonadism.

Analysis of risk factors on hypogonadism in male patients with type 2 diabetes / 中华内分泌代谢杂志

Objective To investigate the risk factors of hypogonadism in male type 2 diabetic patients.Methods A total of 213 male patients with type 2 diabetes were enrolled and divided into low testosterone group (n=75) and normal testosterone group (n=138). Blood pressure, blood glucose, blood lipids, serum insulin and sex hormones including total testosterone (TT), sex hormone binding globulin (SHBG), progesterone, prolactin, estradiol, luteinizing hormone (LH), follicle-stimulating hormone (FSH), dehydroepiandrosterone (DHEA) were measured in all patients.The correlations between the metabolic index and sex hormone levels were analyzed.Results Compared with normal testosterone group, body mass index (BMI), fasting insulin (FINS), and homeostasis model assessment insulin resistance (HOMA-IR) levels were significantly increased in low testosterone group(all P<0.05)while LH, FSH, and SHBG levels were significantly decreased(all P<0.05).Pearson correlation analysis showed that TT was negatively correlated with FINS and HOMA-IR(r=-0.142,-0.154, both P<0.05)while positively correlated with LH and FSH (r=0.157, 0.138, both P<0.05).TT level in patients with metabolic syndrome(MS) was significantly decreased (P<0.05).A multiple logistic regression analysis revealed that BMI, MS, HOMA-IR, and LH were significant independent risk factors for hypogonadism.Conclusions Hypogonadism often occurs in male patients with type 2 diabetes,especially in patients with MS.BMI, HOMA-IR, LH, and MS are risk factors for hypogonadism in male type 2 diabetic patients.

Update on the diagnosis and treatment of menopause syndrome / 中国基层医药

With the advance of medicine and the extension of life expectancy,the proportion of elderly people is increasing around the world,so is the postmenopausal women in the world~ population.More and more women will be bothered by various perimenopausal problems.Vasomotor symptoms(VMS) and the genitourinary syndrome of menopause(GSM) are recognized as the most frequent symptoms associated with menopause.Menopausal hormone therapy (MHT) is the most effective intervention for management of these symptoms.However,the role of MHT in the prevention of cardiovascular disease,skeleton,urogenital systems remains controversial.New drugs such as selective estrogen receptor modulators are equivalent to MHT on the relief of VMS.In addition,it can also prevent bone loss,becoming a new research highlights.Nonhormonal management is an important consideration when hormone therapy is not an option because of medical contraindications or a woman's personal choice,like lifestyle changes,selective serotonin reuptake inhibitors,serotonin-norepinephrine reuptake inhibitors,vaginal laser and etc.
