Reinforcing kidney-yin for kidney-yin deficiency; reinforcing kidney-yang for kidney-yang deficiency; reinforcing kidney-yin and yang for deficiency of kidney-yin and yang; tonifying the kidney essence and soothing liver-qi stagnation for deficiency of kidney and liver depression. [Conclusion] Treatment of premature ovarian failure is based on tonifying kidney, supplement on soothing liver, while some change therapies, should combine disease with syndrome.

With the improvement of China's population aging and health care consciousness, female pelvic floor dysfunction gets increasing attention in society. Modern TCM scholars conclude TCM doctors’ theories about etiology and pathogenesis of pelvic floor dysfunction, summarized as debility of Chong Ren meridians and inability to lift, and then they advocated invigorating qi and elevating yang, with a purpose to protect pelvic floor stability. This article conducted relevant discussion on the significance of rehabilitation of pelvic floor dysfunction based on TCM adjusting qi activity.

BACKGROUND: 5-azacytidine (5-Aza) has been frequently used to induce bone marrow mesenchymal stem cells (BMSCs)differentiation into cardiomyocyte.OBJECTIVE: To observe expression of cardiomyocyte-related receptors in cardiomyogenic differentiation of rat BMSCs.METHODS: BMSCs of passage three were assigned to four groups: group Ⅰ: L-DMEM solution alone was replaced; Ⅱ:L-DMEM solution was replaced after induction of 100 mg/L AST+5 μmol/L 5-Aza for 24 hours; group Ⅲ: L-DMEM solution wasreplaced after induction of 10 μmol/L 5-Aza for 24 hours; and group Ⅳ: L-DMEM solution was replaced after induction of 5 μmol/L5-Aza for 24 hours. Culture medium was replaced every 3 days in each group. Differentiated cells were identified after 30 days ofinduction.RESULTS AND CONCLUSION: Expression of cardiomyocyte specific proteins Nkx2.5, cTnT and Desmin was detected in groupsⅢ, Ⅳ and Ⅱ after induction compared with group Ⅰ , with significant differences (P < 0.01). The amount of cTnT and Desminexpression expression was significantly higher in groups Ⅱ and Ⅲ compared with group Ⅳ (P < 0.01). The level of Nkx2.5expression was significantly higher in groups Ⅱ (P < 0.01) and Ⅲ (P < 0.05) compared with group Ⅳ. No Nkx2.5, cTnT andDesmin espression was detected in group Ⅰ. After induction for 2 weeks, cells with spontaneous contractility were observed ingroups Ⅱ and Ⅲ, indicating differentiation towards cardiomyocyte after induction. Results demonstrated that induction effectswere similar between 100 mg/L AST+5 μmol/L 5-Aza and 10 μmol/L 5-Aza. This may contribute to cytoprotective effects of AST,which can promote vascular endothelial cell proliferation, enhance celss tolerance to 5-Aza-induced cytotoxicity and upregulatecardiac-specific protein expression.

AIM:To treat the chemotherapy-induced premature ovarian failure ( POF) rats with the methods of tonifying kidney yin and yang by observing the indicator changes in apoptosis of ovarian granulosa cells and related cyto -kines before and after medication .METHODS:SD rats ( n=36) were chronically given intraperitoneal injection of cyclo-phosphamide ( CTX) for 15 d in order to establish the animal model of POF .The rats were randomly divided into control group, CTX group, CTX+kidney yin group and CTX +kidney yang group.The levels of tumor necrosis factor alpha (TNF-α) and interferon gamma ( IFN-γ) in the peripheral blood were detected by ELISA .The apoptosis of ovarian granulosa cells was observed by TUNEL method .The levels of apoptosis related proteins were determined by Western blot .RE-SULTS:After modeling , the levels of TNF-αand IFN-γin the peripheral blood were significantly increased .The protein expression of Bax was up-regulated and Bcl-2 was down-regulated .The apoptosis of ovarian granulosa cells was significantly induced with a deep staining .After treatment with tonifying kidney yin and yang , the levels of TNF-αand IFN-γin the pe-ripheral blood were decreased , the protein expression of Bax was down-regulated and Bcl-2 was up-regulated, and the apop-tosis of ovarian granulosa cells was reduced .CONCLUSION:The reserve function of the ovarian can be recovered by pre-scriptions of tonifying the kidney yin and yang via regulating the expression of TNF -α, IFN-γ, Bax and Bcl-2, and inhibi-ting the apoptosis of ovarian granulosa cells .

Objective To explore the atypical ultrasonic appearances of breast fibroadenoma and analyze the cause of mis diagnosis.Methods A total of 493 lesions in 485 patients of breast fibroadenoma detected by ultrasound examination andconfirmed by pathology were retrospectively analyzed.Atypical appearances were analyzed and misdiagnosis rate were cal-culated.Statistical methods were taken to compare the misdiagnosis rates in lesions with various atypical appearances andthose with none or single atypical appearance.Misdiagnosis rates in lesions with different sizes and pathological types wereanalyzed statically.Then misdiagnosing causes were analyzed.Results A total of 404 lesions were diagnosed correctly,in-cluding 99 lesions with atypical appearances,and the other 89 lesions were misdiagnosed,which showed atypical appear-ances.The misdiagnosis rate of lesions with ≥2 atypical features was higher than that with none or single atypical feature(x2 =256.40,P＜ 0.05).Large lesions (maximum diameter＞ 3 am) showed higher misdiagnosis rates than small ones(maximum diameter ≤3 cm,x2=6.73,P＜0.05),and complex fibroadenoma lesions also showed higher misdiagnosisrate than simple ones (x2 =188.01,P＜0.05).Conclusion The lesions with various atypical appearances,large size andcomplex fibroadenoma in pathology are easy to be misdiagnosed.
