Phytoestrogens, which can bind with estrogen receptor and produce estrogen-like effects, are a kind of nonsteroidal compound in plant. Phytoestrogens chemically include isoflavones, coumarins, lignans and other compounds. Phytoestrogens are selective estrogen receptor modulator, and have therapeutical effects on breast cancer, prostate cancer, cardiovascular disease, menopausal symptoms, osteoporosis and other disease, however, do not produce stimulatory hyperplasia effects on uterus, mammary glands and other tissues and organs with positive estrogen receptor. Long-term exposure or excessive use of phytoestrogens maybe affects male reproductive system and hematopoietic function of fetus. Some questions need to be further studied, such as evaluation criteria on biological activity, adverse effects, and action mechanism of phytoestrogen. This review covers plant sources, chemical structure, pharmacological activity and safety of phytoestrogens. It will provide a useful reference for intensive research and rational utilization the phytoestrogens.

The present study was to investigate the role of dopamine D1 receptors and its relationship with glutamate, N-methyl-D-aspartic acid (NMDA) receptor and α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA) receptor in depression induced by chronic unpredictable mild stress (CUMS). CUMS-induced depression model was established in Sprague-Dawley rats, and intrahippocampal microinjections of D1 dopamine receptor agonist SKF38393, non-competitive NMDA receptor antagonist MK-801 and AMPA receptor antagonist NBQX were respectively adopted by rat brain stereotaxic coordinates. The behavioral observations were conducted by measurement of weight changes, sucrose preference test, open-field test and tail suspension test. The concentration of glutamic acid and the expression of its receptors' subunits were detected by HPLC and Western blot, respectively. The results showed that, compared with control group, CUMS rats showed depression-like behavioral changes, higher concentration of glutamic acid, lower expressions of NMDA receptor (NR1) and AMPA receptor (GluR2/3) in hippocampus. Pretreatment with injection of SKF38393 could rescue such depression effect of CUMS, decrease the concentration of glutamic acid, and increase the expressions of NMDA receptor (NR1), AMPA receptor (GluR2/3) in hippocampus. Pretreatment with MK-801 could enhance the antidepressant effect of SKF38393, while NBQX weakened. These results suggest that agonists of D1 dopamine receptor could reduce the concentration of glutamic acid in hippocampus, and its antidepressant effect may be mediated by AMPA receptor partially.

ObjectiveTo evaluate the clinical application of bidirectional Glenn shunt without extracorporeal circulation(ECC) on treatment of children with complicated congenital heart disease (CHD).MethodsForty-six patients with complicated CHD(without ECC group) underwent bidirectional Glenn shunt without ECC,and 40 patients with complicated CHD (with ECC group) underwent bidirectional Glenn shunt with ECC.The therapeutic effect was compared between two groups.ResultsThere was no operative mortality in two groups.The pulmonary artery pressure in without ECC group was significantly lower than that in with ECC group [( 16.7 ± 1.2) mm Hg ( 1 mm Hg =0.133 kPa) vs.( 18.9 ± 1.0) mm Hg,t =4.686,P=0.026 ].Duration of respirator assistance after operation in without ECC group was significantly lower than that in with ECC group [ ( 12.2 ± 2.7) h vs.( 19.2 ± 2.8) h,t =2.972,P =0.041 ].There was no significant difference in saturation of blood oxygen and the rate of chylothorax after operation between two groups (P＞0.05).The symptoms and signs including cyanosis and breath were markedly alleviative in all patients.ConclusionBidirectional Glenn shunt without ECC is an effective and safe method for complicated CHD.

Objective To explore the relationship between sleep quality and quality of life in patients with type 2 diabetes. Methods Multi-stage randomized cluster sampling was used in the survey and self-designed questionaire , Pittsburgh sleep quality index scale , diabetes specific quality of life scale and self-rating depression scale were adopted. Results The poor sleep quality rate was 33.6%. Compared with the group with 6~8 h sleep duration, the scores of physical function,psychological dimension,social relations and quality of life were higher in patients with < 6 h sleep duration (P < 0.01).The average quality of life score was significantly higher among the sleep disorder participants than the other groups(56.95 ± 14.57 vs 50.11 ± 11.08 vs 44.77 ± 9.61,P<0.01). After adjusting for age, gender, complications, course of disease and depression, etc. The correlation coefficient of sleep quality and quality of life was 3.92. Among them , the sleep quality and physical dimensions of the correlation coefficient is the largest(r=0.407,P<0.01). Conclusions It can be an effective method of improving their status of life quality by ameliorating their sleep quality , especially for the physical dimension.

Objective To understand the prevalence and influencing factors of overweight and obesity in adult residents in Xuzhou City of Jiangsu Province,so as to provide scientific basis for health policies and intervention strategies.Methods A total of 39 445 participants were recruited by multi-stage random cluster sampling method,and health data were obtained through questionnaires and physical examinations.Results The prevalence of overweight and obesity was 34.60％ and 9.40％,respectively; and the standardized prevalence was 32.97％ and 8.67％.The prevalence of overweight or obesity in males was 36.73％ and 8.62％,in females 32.61％ and 10.13％.The prevalence of overweight or obesity was increased with age,although the prevalence of overweight was decreased after 55 years of age (18-:16.31％; 25-:27.38％; 35-:37.28％; 45-:41.55％; 55-:40.71％; 65-:37.64％; 75-:32.08％) and the prevalence of obesity was decreased after 75 years of age (18-:2.49％; 25-:6.41％; 35-:9.64％; 45-:11.24％; 55-:12.07％; 65-:12.45％; 75-:8.88％).There were significant difference of the prevalence of overweight/obesity by educational level (x2=178.41,P＜0.01; x2=243.59,P＜0.01),profession (x2=191.28,P＜0.01; x2=120.38,P＜0.01) and marital status (x2=431.67,P＜0.01; x2=118.43,P＜0.01).In Logistic regression,female,vegetable over-intake every day and current cigarette smoking were protective factors of overweight/obesity,while middle and old-age,alcohol drinking and big appetite were risk factors of overweight/obesity.Conclusions A higher morbidity rate of overweight/obesity was found in Xuzhou City,and comprehensive interventions should be taken for high risk populations.

Background Previous studies showed that after herpes simplex virus-1 (HSV-1) infection of the cornea,matrix metallo proteinase-2 (MMP-2) (produced by corneal cells and corneal epithelial cells) plays an important role in the development of HSK.Focal adhesion kinase (FAK)plays an important role on the expression,release and activation of MMPs.This study explored the expressions of MMP-2 and FAK,which induced by HSV-1 infected human corneal epithelial cells.Objective To investigate MMP-2 and FAK expression in HSV-1 infected human corneal epithelial cells.Methods Human corneal epithelial cells were infected with HSV-1 in vitro to establish cell model of viral infection.The expression of MMP-2 and FAK were detected by reverse transcription PCR (RT-PCR),Western blot,immunohistochemical method and immunofluorescence method at 2 hours,20 hours and 40 hours after infection.Results At 2 hours,20 hours and 40 hours after infection,the expressionis of MMP-2 mRNA and FAK mRNA were significantly increased in comparison with uninfected cells (MMP-2 mRNA:Ftime =0.968,P=0.436 ; Fgroup =47.649,P =0.000 ; Fi ion =0.757,P =0.536.FAK mRNA:Ftime =0.658,P =0.631 ; Fgroup =35.182,P=0.000;Finteraction =1.386,P=0.137).Western blot assays showed that there were no significant differences in p-FAK,FAK or MMP-2 expressions between infected cells and control cells after 2 hours (P＞0.05),but the expression levels of infected cells were significantly increased at 20 hours and 40 hours (both at P ＜ 0.05).Immunohistochemistry results showed that longer infection time was associated with an increased number of cells staining for MMP-2,FAK and p-FAK.Conclusions At the initial stage of HSV-1 infected,p-FAK plays an important role in the process of virus invading and MMP-2 activation.
