Phytoestrogen is a kind of plant element which is similar to animal estrogen. Phytoestrogens can prevent progreator system cancer, cardiovascular disease and osteoporosis. Recently more and more researches are reported on the protection of phytoestrogens on central nerve system.

ObjectiveTo study the symptom dimensions of obsessive-compulsive disorder(OCD) of Chinese patients.MethodsThis study examined apriori categories used to group types of obsessions and compulsions in the Yale-Brown Obsessive Compulsive Scale symptom checklist,in a group of Chinese patients with OCD ( n=536).A principal-components factor analysis with a varimax rotation was performed.ResultsFive factors( explaining)-hoarding( 16.17％ ),contamination/cleaning ( 13.65％ ),symmetry/ordering( 12.82％ ),aggressive/checking( 10.44％ ),somatic/repeating(8.38％ )-emerged in this analysis,in total accounting for more than 60％ of the variance.ConclusionThe result suggests a multidimensional model of Chinese OCD patients and these five factors may be helpful in identifing the subtype of OCD.

Objective To evaluate the effects of external substance P (SP) on scalding wound healing and neovascularization.Methods Eighty-four Wistar rats were induced into diabetic models by intraperitoneal injection of streptozotocin (STZ), and deep partial thickness scalding wound on the back with diameter of 2 cm was prepared. Rats were randomly divided into experiment group (n=42, local injection of SP) and control group (n=42, local injection of PBS). The process of wound healing was observed, and the percentages of wound closure were calculated on D0, D1, D3, D7, D10, D14, D21 post scald. The expression of CD31, surface marker of neovascular endothelial cells, was detected within the wound sites by immunohistochemical staining, and the microvessel density was calculated. Results The percentage of wound closure in experiment group was significantly higher than that in control group on D7 post scald [(42.69±3.26) % vs (30.24±1.17)%, P<0.01]. Immunohistochemical detection revealed that the expression of CD31 and the microvessel density in experiment group were significantly higher than those in control group from D7 post scald (P<0.01). ConclusionExternal SP may promote scalding wound healing in diabetic rats, the mechanism of which may be associated with upregulation of expression of CD31 and acceleration of neovascularization.

ObjectiveTo explore the role of β-catenin in the proinvasive consequences of hypoxia in hepatocellular carcinoma (HCC).MethodsWe established in vitro and in vivo hypoxic models using the highly metastatic MHCC97 and the stable red fluorescent protein-expressing MHCC97-R cells.The role of β-catenin in hypoxia-mediated aggressiveness was investigated by β-catenin knockdown.ResultsHypoxia caused a pronounced arrest of proliferation in MHCC97 cells,suppressed tumor growth in MHCC97-R xenografts,but promoted in vitro invasiveness and in vivo metastasis.β-Catenin-silencing by short hairpin significantly inhibited the enhanced invasiveness of MHCC97 cells due to hypoxia,reduced the increase in distant metastasis by hepatic arterial ligation,but failed to further restrain cell proliferation.Conclusionβ-Catenin in HCC cells plays an essential role in the hypoxia-induced metastatic potential.A reduction of βcatenin expression inhibited the proinvasive consequences of hypoxia in HCC.

Objective To study the effects of granulocyte-macrophage colony stimulating factor (GM-CSF) on the expression of vascular endotllelial growth factor (VEGF) in human dermal fibroblast. Methods In vitro human dermal fibroblasts in good status were incubated with GM-CSF (GM-CSF group) or non-GM-CSF (control group) culture medium for different periods of time. The mRNA, protein expression of VEGF in derma fibroblast were determined by reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting, respectively, and the secretion of VEGF in supernatant was measured by enzyme linked immunosorbant assay (ELISA). Results The expression of VEGF mRNA from dermal fibroblasts was increased significantly after l or more hours of incubation with GM-CSF comparing with the control (P＜0.05). 6 hours of stimulation by GM-CSF caused maximal expression of VEGF mRNA. The expression of VEGF protein in dermal fibroblasts was increased from 12 hours and was peaked at 24 hour after stimulation by GM-CSF. VEGF protein from the supernatant of the dermal fibroblasts was also raised persistently from 12 hour after stimulation by GM-CSF and was improved remarkably compared with the control. Conclusions GM-CSF can up-regulate directly the expression of VEGF in human derma fibroblast, which may be one of the mechanisms that GM-CSF accelerates neovascularization in wound healing.

0.05).The protein and mRNA expression of MIP-2 in high glucose group significantly increased after culture for 4 h,and guadually decreased then.The protein and mRNA expression of MCP-1 began to increase significantly after culture for 8 h,reached peak at 12 h,and slightly decreased after culture for 24 and 48 h. Conclusion High glucose promotes the protein and mRNA expression of MIP-2 and MCP-1 from mouse peritoneal macrophages cultured in vitro,which indicates that high glucose may delay the wound healing by increasing the expression of chemokines in diabetic mice.

Objective To study the association between endometrioid uterine carcinomas and metabolic syndrome (MS). Methods A retrospective study was conducted on 123 patients who were admitted in Department of Gynecology Oncology, Zhejiang Cancer Hospital (study group) and 90 healthy women (control group) with matching age from Jan. 2005 to Mar. 2009. The general conditions[including age, whether menopausal, body mass index (BMI)];the risk factors for MS [including waist circumference,fasting plasma glucose, triglycerides(TG), high-density lipoprotein (HDL) and systolic and diastolic blood pressure]were analyzed. The clinical stage, histological type, and pathology differentiated degree of study group with or without MS were also analyzed by univariate analysis and Cox proportional hazards models.Results (1) The univariate survival analysis shown that there were no significant difference with age in two groups[(54.3±0.6) vs. (54.2±0.9) years;P>0.05], while the rate of menopausal, BMI(≥25 kg/m~2), the cases coupled with MS, the size of waist circumference (> 80 cm), the level of fasting plasma glucose (≥5.6 mmol/L),TG(> 1.7 mmol/L)and abnormal systolic and diastolic blood pressure in study group were higher than those in control group (67.5% vs. 48. 9%, 45.5% vs. 23.3%, 43.9% vs.18.9%, 50.4% vs. 27.8%, 53.7% vs. 21.1%, 40.7% vs. 21.1% and 40.7% vs. 25.6%,respectively, all P <0.05). The percentage of HDL(< 1.30 mmol/L) was higher in study group than that in control granp(63. 4% vs. 32. 2%, P <0.05). (2) There were not significant difference for the clinical stage, pathological type, grades between patients with or without MS in study group (P > 0.05). (3) The Logistic multivariate survival analysis shown that central obesity, higher TG, lower HDL and abnormal plasma glucose were independent risk factors for endometrioid uterine carcinomas coupled with MS (P< 0.05). Conclusion Metabolic syndrome is marginally associated with an increased risk of endometrioid uterine carcinomas, which may be the new point to screen, prevention and treatment endometrioid uterine carcinomas.

Objective To observe the effect of reperfusion therapy on the prognosis of acute myocardial infarction (AMI) complicated by eardiogenic shock(CS)in reperfusion era.Methods 89 cases of AMI with CS were included with 57 male and 32 female.50 cases received conservative therapy and 39 cases reperfusion therapy.28 of the 39 cases had suecessflll reperfusion and 11 eases failed.18 patients had intra-aortic balloon pump (IABP) within 1 hour of CS,they constituted an early group;35 patients treated with IABP 1 hour after CS were of a late group.A group of 36 cases were not treated with IABP (no IABP group).Results The mortality of the early group with IABP Was significantly lower than that of the late and no IABP group(33.3% vs.74.2% vs.86.1%,P＜0.01).The mortality of the group with sucessful reperfusion was significantly lower than that of unsuccessful reperfusion and conservative no IABP group (42.8% vs.81.8% vs.84.0%,P＜0.01).logistic regression analysis showed that successful reperfusion therapy (OR 4.232,95% CI 1.407～12.730,P=0.01) and THE TIME of using IABP(OR 0.22.95% CI 0.063～0.764,P=0.017)were independent risk factors for death.Conclusion Early successful reperfusion and early institution of IABP were the most important therapeutic measures for reducing mortaliIv of AMI complicated by CS.
