1.Cardiovascular disease in postmenopausal women with polycystic ovary syndrome phenotype
Chinese Journal of Endocrine Surgery 2015;(5):411-414
Objective To explore cardiovascular disease in postmenopausal women with polycystic ovary syndrome(PCOS) phenotype.Methods This study was a prospective follow-up study which included subjects with PCOS phenotype admitted from Jan.1st, 2005 to Dec.31st, 2007 in Gynecology Department of Dongyang People's Hospital.These subjects were divided into two groups according to the presence or absence of PCOS phe -notype and were followed .Kaplan-Meier method was used to estimate survival rate .The survival difference be-tween the two groups was compared using the log-rank test.Multivariate Cox proportional hazards regression was used to determine the independent risk factors of major adverse cardiac events ( MACE) .Results 11 patients in non-PCOS phenotype group had MACE , and 6 patients in PCOS phenotype group had MACE .PCOS phenotype group had a significantly decreased MACE-free survival(χ2 =4.957,P=0.026).Multivariate Cox proportional hazards regression analysis showed that low level of HDL-C, presence of PCOS phenotype and high level of hs-CRP were independent predictors for MACE .Conclusion PCOS phenotype is an independent risk factor for car-diovascular disease in postmenopausal women , help to make further risk stratification and shows cardiovascular disease is closely related to PCOS .

Objective To explore the relationship between nonalcoholic fatty liver (NFALD)and apolipoprotein E (ApoE)gene polymorphism in Shanghai undergraduate students. Methods A cross-sectional survey was performed in 4 148 students from Shanghai Tongji University. Quesgionary, physical measurement, ultrasonography and biochemical parameters were used to diagnose NFALD. In patients with NAFLD and 200 healthy subjects (served as control), ApoE genotypes were determined by PCR-RFLP. Results (1)Totally 398 subjects were diagnosed as NAFLD (prevalence 9.6%). Body mass index, waist-to-hip ratio, triglycerides, total cholesterol, alanine transaminase, aspartate aminotransferase and γ-glutamyltransferase in NAFLD group were higher than those in control, which were related to the degree of NAFLD (P<0.01). (2)ApoE genotypes distributions were significantly different between two groups (χ2=10.52, P<0.01). In NAFLD,E4/4 genotype frequency (5.5%)increased, and E3/3 (61.8%)decreased . (3)Unconditional logistic regression showed that E4/4 were closely associated with lipid profiles. Conclusion ApoE point mutations 112 and 158 may cause different dyslipidosis. E4/4 genotype seems to be one of the genetic predisposition factors of NAFLD.

Objective] To explore the theoretical origin, clinical application method, effect and practical significance of the treatment of ectopic pregnancy with blood stasis. [Method] From blood stasis on the treatment by promoting blood circulation to remove blood stasis, Yiqi Yangxue Huayu Shapei, expelling blood circulation, method to eliminate the disease, stage of treatment, a reasonable choice of promoting blood circulation and removing blood stasis drugs in the treatment of ectopic pregnancy. [Results] From blood stasis on the treatment of ectopic pregnancy, it can accelerate the beta HCG negative, and speed up the ectopic pregnancy mass absorption, clinical curative effect significantly, the greatest degree of protection of fallopian tube integrity, improve blood circulation, and tubal function recovery, increase after treatment the chances of conception. [Conclusion] Qi stagnation, blood stasis and Qi deficiency and blood stasis are ectopic pregnancy basic pathogenesis, less empirical abdominal blood stasis is the essence of its pathogenesis. The existence of blood stasis in ectopic pregnancy of each type and disease development of the whole process, in the occurrence of the disease, and occupies an important position in the development, promoting blood circulation and removing blood stasis is the basic treatment, should be in clinical dialectical treatment of the whole process of fusion.

Objective To investigate the effects of quercetin on the proliferation of mammary cancer cell in vitro. Methods Effects of quercetin on the cell proliferation was tested in ER-positive MCF-7 cell and ER-negative MDA-MB231 cell by MTT measurement. And to evaluate the estrogen-like effect of quercetin and its relation with the estrogen-receptor by pure estrogen receptor antagonist ICI 182, 780 as a tool. Cell cycle was examined by flow cytometry. Result Quercetin (10~50 ?mol/L) stimulated proliferation of ER-positive MCF-7 cell compared with solvent control, whereas ER-negative MDA-MB231 cell proliferation effect was inhibited, and the cell cycle was impulsed from G1 to S, DNA synthesizing was inhanced, PI was also increased. The above function on boosting MCF-7 cell proliferation can be inhibited by adding estrogen receptor antagonism ICI182, 780. Conclusion Quercetin has the estrogen-like activities through the estrogen response pathway.

Objective To study the molecular mechanism of MPTP-induced neuronal degeneration of substantia nigra in C57BL mice. Methods The C57BL mice model of Parkinson's disease were prepared by peritoneal administration of MPTP. These differentially expressed sequenced tags (EST) were obtained with mRNA differential display technique. Reverse Northern blotting was employed to eliminate the false positive ESTs. The true positive EST were cloned and sequenced. Results One of the two specific EST in degenerative substantia nigra was sequensed to be 121 bp and showed low homology with human v-abl Abelson murine leukemia viral oncogene (abl) exon 1b. Conclusions Our data suggested that MPTP may induce altered expression of promoting apoptotic genes to cause neuronal degeneration in substantia nigra.
