Professor ZHANG Liang-ying in Yunnan University of Traditional Chinese Medicine conducted TCM adjuvant therapy for in vitro fertilization - embryo transfer (IVF-ET) of infertility patients, which has obtained satisfactory results. The use of kidney-based, disease differentiation combined with the treatment, emphasizing preoperative conditioning, psychological adjustment, and appropriate choice, can help improve the IVF-ET pregnancy rate and complications of many problems.

Polycystic ovary syndrome (PCOS) and dysfunctional uterine bleeding (DUB) are common gynecologic endocrine diseases, and their etiology, pathology, diagnosis and treatment are related but also distinguishing. Some patients have PCOS and DUB at the same time, which is difficult to cure. Professor ZHANG Liang-ying has treated these patients with staging treatment based on syndrome differenciation, and has received desiable efficacy.

AIM: To investigate the expression and function of apoptosis-related protein, Fas, FasL, and Bcl-2 in the pathogenesis of autoimmune thyroiditis. METHODS: Immunohistochemical staining was performed on 20 Hashimoto's thyroiditis (HT), 20 Graves' disease (GD), and 20 thyroid follicular adenoma (TFA, as control). RESULTS: All the cases expressed Fas, mainly on the cell surface and cytoplasm. FasL was found in all except 3 of the TFA. Bcl-2 in 15 of HT, 19 of GD, 17 of TFA. In TFA follicular cells expressed moderate Fas and minimal or absent FasL. In HT, follicles adjacent to infiltrating lymphocytes showed a increased levels of Fas and FasL, but infiltrating lymphocytes exhibited weaker staining of Fas and FasL than thyrocytes. In GD, thyrocytes and lymphocytes showed nearly similar Fas with HT, but rather weaker for FasL than HT. Bcl-2 was nearly similar in GD and TFA, but follicular cells in vicinity of lymphocytes and lymphocytes located in germinal centers of HT tissues exhibited significantly weaker. CONCLUSION: The expression of Fas, FasL and Bcl-2 in Hashimoto's thyroiditis and Graves' disease was nearly similar. Strong FasL expression and weak Bcl-2 expression on the follicles in HT may induce apoptosis. These results provide further proof that the functions of Fas and its ligand and Bcl-2 may play an important part in the pathogenesis of autoimmune thyroid diseases. The lymphocytes do not seem to be directly engaged in the process with their own FasL, but they may provide some cytokines that, in turn, up-regulates Fas and/or FasL leading to apoptosis.

Objective:To observe the effects of electroacupuncture on the expression of cortical solute carrier family 7 member 11(SLC7A11),glutathione(GSH)and glutathione peroxidase 4(GPX4)in rats with post stroke spasticity(PSS),and to explore the mechanism of electroacupuncture in the treatment ferrozosis in PSS.Methods:Thirty SD male rats were randomly divided into sham group,model group and electroacupuncture group.A modified Zea-Longa wire bolus+internal capsule injection NMDA method was used to produce a rat model of PSS.In the electroacupunc-ture group,the affected side of Yanglingquan and Quchi were needled once/day for 30 min/time for 7 d.In the sham group and the model group,only fixation without intervention was performed during the same period.Zea-Longa Neuro-logical Function Score was used to detect the neurological function of rats,electrophysiological tracing method was used to detect the muscle tone of rat quadriceps,Western Blot was used to detect the protein expression of rat cortical SLC7A11 and GPX4,Enzyme-linked immunosorbent assay(ELISA)was used to detect the GSH content of rat cortex,and real time RT-PCR was used to detect the mRNA of rat cortical SLC7A11 and GPX4 mRNA expression.Results:Neurological function scores were elevated;quadriceps muscle tone was increased;GSH content was decreased;the protein expression of SLC7A11 and GPX4 was significantly decreased;the expression of SLC7A11 mRNA and GPX4 mRNA was significantly decreased.Electroacupuncture treatment resulted in lower neurological function scores,lower quadriceps muscle tone,increased GSH content in rat cortex,significantly up-regulated protein expression of SLC7A11 and GPX4,and significantly increased expression of SLC7A11 and GPX4 mRNA.Conclusion:Electroacupuncture on"Yanglingquan"and"Quchi"could improve limb spasticity and promote the recovery of neurological function in PSS rats,and its mechanism of action may be related to the inhibition of ferroptosis of cortical cells by electroacupuncture regulating the SLC7A11 and GPX4 expression.
