Objective To observe the effect of grape seed Procyanidins on platelet aggregation and experimental thrombosis in rats.Methods 50 Experimental thrombosis male SD rats of clean grade,weighing 250～300 g,were randomly divided into five groups,normal saline(control)group,aspirin(ASP)group(60 mg/kg),and procyanidins 1 00 mg/kg,200 mg/kg,400 mg/kg group,10 in each.50 experimental thrombosis male Kunming mice of clean grade,weighing 18～20 g,were also randomly divided into five groups,normal saline(control)group,aspirin group(84 mg/kg)and Procyanidins 140 mg/kg,280 mg/kg,560 mg/kg group,10 in each.Intragastric administration was performed in these experimental animals.The effects of Procyanidins were observed on rat platelet aggregation induced by ADP,COL and AA.Experimental rat's thrombosis was induced by method of"arterio-venous"shunt and the death rate within 15 min was determined with collagen plus adrenaline induced thrombus model in mice,aspirin as a positive control.Results Procyanidins in the middle and high-dose group can inhibit ADP,COL,AA-induced platelet aggregation and experimental thrombosis obviously.Conclusion Procyanidins can inhibit experimental thrombosis and have anti-platelet aggregation effect.

Objective The currently pertinent articles about the molecular mechanism of recurrence and metastasis of primary hepatocellular carcinoma (HCC) were reviewed. Methods Literatures that related to the molecular mechanism of the recurrence and metastasis of HCC were summarized retrospectively in this review. Results Several genes, such as the growth factors and the corresponding receptors, the adhesive molecule, and the extracellular matrix and many factors, such as the oxygen supply, tumor angiogenesis and the immune system, all took important roles in the process of recurrence and metastasis of HCC, which involves many steps. Conclusion The study of the recurrence and metastasis of HCC should be emphasized further since early intervening the genes that are related to the recurrence and metastasis may help prevent the recurrence and metastasis of HCC completely, decrease the death rate and improve patients’ life quality in the long term.

0.05). In the general anesthesia group, glucose level at 10 minutes after pneumoperitoneum was significantly lower than that before anesthesia (P0.05). Conclusion Both epidural and general anesthesia can effectively inhibit the patients' stress response in laparoscopic gynecological operation.

ADVANCE trial demonstrated that stable intensive glucose control could improve prognosis and the target HbA1c should be 6.5%.While ACCORD and VADT trials suggested aggressive glucose lowering in diabetics at high cardiovascular risk is potentially harmful,tight glucose control yields no significant effect on long duration,poorly controlled patients with complications.DCCT and UKPDS research confirmed benefits of early intensive glucose control could persist due to legacy effect.Steno-2 research showed patients benefit greatly from comprehensive control of risk factors.In sum,early intensive control of risk factors and individualized treatment in diabetics are mainstream therapy.

Objective To evaluate the inhibitory effects of NF-κB inhibitor pyrrolidine dithiocar-bamate (PDTC) on NF-kappa B activity and the serum inflammatory mediators in hypertensive-ventricular hypertrophy-congestive heart fail?ure rats. Methods The rat model of hypertension-cardiac hypertrophy-heart failure was made from 42 male Dahl salt sen?sitive rats. Rats were randomly divided into seven groups including group A (normal diet group), group B (high salt diet group), group C (NF-κB inhibition in early stage), group D (NF-κB inhibition in hypertensive stage), group E (NF-κB inhibi?tion in cardiac hypertrophy stage of week 12) and group G (NF-κB inhibition in heart failure stage). There were six rats for each group. Rats were administrated 8%high salt diet and injected PDTC 100 mg/(kg·d)intraperitoneally according to the prescribed time. Changes of blood pressure, left ventricular end diastolic interventricular septal thickness (IVSD), left ven?tricular end diastolic posterior wall thickness (LVPWD), left ventricular end diastolic diameter (LVEDD), systolic left ventric?ular end diastolic diameter (LVESD), left ventricular ejection fraction (LVEF), heart, lung weight/ body weight ratio, NF-kappa B activity, tumor necrosis factor (TNF)-α, interleukin (IL)-6, monocyte chemotactic protein (MCP)-1 and C-reactive protein (CRP) were observed in different treatment time points of PDCT. Results Levels of NF-κB and proinflammatory cy?tokines were reduced after early administration of PDTC, and the cardiac function was also decreased. The longer the treat?ment time, the greater the protective effect on heart. PDTC can effectively control blood pressure, and block left ventricular hypertrophy and left ventricular failure in a certain extent. The effects of PDTC were limited after persistent hypertension, and myocardial hypertrophy formation accompanied by heart failure. Conclusion PDTC plays a role in prevention and treatment of hypertension, left ventricular hypertrophy and congestive heart failure in model rats. Early application of PDTC could obviously maintain the normal cardiac function in rats with heart disease.

Objective To evaluate the influence of international normlized ratio(INR) self-management intervention on the complication of patients after mechanical heart valve replacement (MHVR).Methods The randomized controlled trials (RCT) about comparing the INR self-management with conventional management in patients after MHVR were researched by the database of PubMed, Medline, China Biomedical Literature Database, Wanfang data, Chinese National Knowledge Infrastructure, and the data were analyzed by Stata 12.0 software.Results Nine RCTs were enrolled in this study, 4 265 cases in total.The results of Meta-analysis showed that INR self-management could reduce the incidence of thrombosis, relative risk(RR) was 0.68, 95％ confidence interval (95％CI) was 0.50-0.94, P＜0.05.However, there was no significant difference in hemorrhage between the two groups, yet could not evaluate the effect on INR values within the target range, RR(95％CI) was 1.29(1.20-1.38), P＜0.05.But due to the high heterogeneity in literature, the results were for reference only, it remained to be further argumen.Conclusions INR self-management can reduce the incidence of thrombosis in patients after mechanical heart valve replacement, and does not increase the risk of bleeding complication at the same time.

Objective To study the expression of VEGF, MMP-2 and MMP-9 in benign and malignant lesions of breast and their effects on breast carcinoma's invasiveness and metastasis. Methods VEGF,MMP-2 and MMP-9 expression was detected by SP method in 20 breast fibroadenoma and 12 normal breast specimens taken from non-cancerous regions adjacent to breast cancer tissue and 38 breast carcinomas. Results The expression rate of VEGF, MMP-2 and MMP-9 in breast carcinoma was remarkably higher than those in normal breast tissue and breast fibrogdenoma (63.2% vs 25.0% and 30. 0% ,78. 95% vs 33.3% and 35.0% and 71.1% vs 41.7% and 45.0% ,respectively; P ＜0.05). There was a correlation between VEGF, MMP-2 and MMP-9 expression and nodal metastasis ( P ＜0.05). High expression of VEGF, MMP-2 and MMP-9 was correlated with pathological grade ( P ＜ 0.05, respectively). The overexpression of VEGF was related with those of MMP-2 and MMP-9 in breast cancer( VEGF and MMP-2:rs =0.541, P ＜0.01 ;VEGF and M M P-9: rs = 0.11, P ＜ 0.01; MMP-2and M MP-9: rs= 0P ＜ 0.01 ). Conclusion VEGF,MMP-2 and MMP-9 overexpression is strongly related to the invasiveness and metastasis of breast carcinoma, which might be valuable in evaluating tumor invasion and metastasis.
