1.Beneficial cardiovascular effects of statins
Chinese Pharmacological Bulletin 2003;0(11):-
Pleiotropic effects of a drug are actions other than that for which the agents were developed.These effects may be desired or undesired,and may be unrelated to their primary mechanism.Statins were designed as a drug for reducing cholesterol,but now pleiotropic effect are found including improvement of endothelial dysfunction,inhancement of eNOS bioavailability antioxide effect,antiinflammatory properties and reduction of hypertension.Understanding those effects is important for treatment and prevention of cardiovascular disease.

The absorption process is an important factor in determining the bioavailability of orally administered drugs. however, the absorption mechanism of many drugs is not clear. Caco-2 cell model is the best in vitro absorption model nowadays. It is widely used in the research on drug absorption process and absorption mechanism, especially in the aspect of traditional Chinese medicine absorption, the use of Caco-2 cell model has become the hot spot recently. Mo- reover, Caco-2 cell model is also applied in the research on drug metabolism. Therefore, Caco-2 cell model will become an important method in the research of drug absorption, and will be helpful to accelerate the process of new drug screening and development.

Stroke is characterized by a group of acute cerebral vascular diseases which attack acutely with focal neurological deficits. Residual motor deficits often sojourn after stroke. Cortical stimulation, which is a technique developed many decades ago, has recently re-emerged as a promising method for researchers in their quest to causally probe cortical representations of sensorimotor and cognitive functions and to facilitate the treatment of various neuropsychiatric disorders. The article summarizes the research progress of cortical stimulation in the promotion of motor function recovery after stroke, the method of operation, the possible mechanisms and the prospect.

ObjectiveTo summarize the recent therapeutic effects of mesh-plug tension-free hernioplasty in elderly inguinal hernia. MethodsAll cases were performed with mesh-plug case-hardened products, which are manufactured by American Bard Company. ResultsAll the operative procedures were performed smoothly. Postoperative complications were:6 cases of urinary retention,4 scrotal hydroceles,2 persistent wound pain,2 local lightly projections with foreign body sensation,2 hypoincisional haematoma. 1~24 months of follow-up were taken,2 recent recurrences were reported. ConclusionMesh-plug tension-free hernioplasty is a perfect surgical operation. Its main characteristics are:simple performance, less trauma, tension-free, time-saving, good recent therapeutic effect, and fewer recent recurrence. It is especially suitable to the elderly patients and/or Patients with other diseases.

Objective To detect the expressions of p53, vascular endothelial growth factor (VEGF) and microvessel density (MVD) in breast cancer and tumor adjacent tissues to explore their relationship and roles in the pathogenesis of breat cancer. Methods The expression levels of p53,VEGF and MVD were assessed in 110 cases of breast cancer and tumor adjacent tissues with SP immunohistochemical method. Results The positive expression rate of VEGF and p53 was 90.0%(99/110) and 42.7%(47/110) in the breast cancer tissues, and 35.5%(39/110) and 4.5%(5/110) in the tumor adjacent tissues, respectively, which had highly significant difference between two groups (P

Objective:To investigate the role of monocyte chemoattractant protein-1 in the progress that isometric exercise training improves arteriogenesis.Method:Twenty-four male Sprague-Dawley rats were used,weighing (200±20)g.The rats were randomized into control group (CG),myocardial ischemia group (MI),exercise training group (ET),MCP-1 inhibitor group (LG).There were 6 rats in each group.Rats were continuously administered 10mg/kg subcutaneously isoproterenol for successive 2 weeks to establish the myocardial ischemia model.Successfully modeled rats were in groups MI,ET and LG.Isometric exercise training were performed in group ET and LG.The rats in group LG were given MCP-1 inhibitor leflunomide by gavage.After 8 weeks of training,the left ventricular myocardium was extracted and relative collateral blood flow (RCBF) was measured by microspheres.Artery density (AD) and monocytes were measured by immunohistochemistry analysis.Western blot analysis and real-time quantitative PCR were performed to assay protein and mRNA of MCP-1.Result:RCBF and AD increased significantly in group ET as compared to the rest groups.RCBF and AD in group LG showed higher than that in group MI but not significant.The number of monocytes,MCP-1 mRNA and MCP-1 expression were significantly elevated in ischemic myocardium of group ET.Interestingly,the number of monocytes,MCP-1 mRNA and MCP-1 expression showed lower than that in group MI but also not significant.Conclusion:Eight weeks of isometric exercise training can increase the expression of MCP-1 in ischemic myocardium and promote the arteriogenesis.

Objective To discuss the clinical value of high -quality nursing care in patients with diabetic ne-phropathy .Methods 160 patients with diabetic nephropathy were randomly divided into intervention group and control group, 80 cases in each group .The two groups were received the regular treatment and nursing care of diabetic ne-phropathy, while the intervention group further received high -quality nursing measures.The blood glucose, blood lip-id, renal function, oxidative stress index and SAS score were observed after 6 months.Results The blood glucose, blood lipid, renal function and SAS score index were significantly lower than the control group (p<0.05), and the oxi-dative stress index were improved significantly than that in the control group (p<0.05);Conclusion High-quality nursing intervention can obviously improve the psychological status and therapeutic effect of diabetic nephropathy .
