1.Update on thyroid transplantation
Chinese Journal of Endocrinology and Metabolism 2016;32(8):704-706
[Summary] Transplantation of human cell, tissue or organ is an effective means to cure completely the disease. Animal experiments and clinical studies have demonstrated that the efficacies of transplantation are obvious in the treatment of hypothyroidism. In recent years, thyroid stem cell transplantation has drawn much attention, embryonic stem cells, bone marrow mesenchymal stem cells and adult stem cells had also made progress in clinical investigations. Especially the embryonic stem cell transplantation has been used successfully in animal experiments. It provided a new perspective for clinical thyroid transplantation, but it also faces many problems to solve.

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.

AIM: To discuss the effects of phytoestrogenic-genistein on cathepsin K (CK) expression stimulated by interleukin-1α (IL-1α) in osteoclast-like cells (OCLs) . METHODS: The OCLs were isolated from tissue of human giant cell tumor of bone (GCT) . The cells treated with reagents were divided into 7 groups including control (treated with phenol red-free-DMEM), vehicle (treated with 1.2 nmol· L-1 IL- 1α), 10-10-10-6genistein, genistein+ ICI 182.780, and 17[β-estrodiol (17β-E2) group. The cells were treated with 1.2 nmol· L-1IL-1α after pre-treated with genistein or 17β-E2 for 48 h (excluded the control group) . Expression of CK wasdetermined by reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blot in OCLs stimulated by IL-1α in the presence of genistein or 17[β-E2. RESULTS: The obvious increase of expression of CK by IL1α in vehicle group was noted in comparing with control group (P < 0.01 ) . Genistein down-regulated CK gene expression stimulated by IL-1α at the transcription level in a dose-dependent manner (r = 0.68, P < 0.01 ) .Genistein down-regulated CK protein expression stimulated by IL-1α also in a dose-dependent manner (r = 0.61,P < 0.01 ). The effects of genistein were abrogated partly after treatment with the estrogen receptor antagonist ICI 182.780. CONCLUSION: Genistein inhibits CK expression stimulated by IL-1α partly through estrogen receptor in OCLs.
