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.

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 study the antifatigue effect of sea cucumber exstract.Methods According to the experimental methods of animal antifatigue, three doses of sea cucumber extract were applied to mice and their antifatigue effects were compared statistically.Result 300 mg?kg -1 ?d -1 sea cucumber extract could significantly prolong pole climbing time in mice, increase the reserves of liver glycogen and the content of blood glucose, decrease the contents of blood urea nitrogen (BUN) and blood lactic acid after strenuous exercise. Conclusion The preliminary study showed that the sea cucumber exstract has some antifatigue effects.

Objective To study the changes of cytokine activation in patients with chronic congestive haert failure(CHF) as indicated by plasma levels of C-reactive protein(CRP)and its relation to adrenomedullin(ADM) and endthelin-1(ET-1).Methods The plasma levels of CRP,ADM and ET-1 of 60 decompensated haert failure(DHF) patients group and 30 essential hypertension patients with compensated cardiac function(CCF) group were tested. CRP was determined by immunoturbidometry,ET-1 and ADM were determined by radioimmunoassay.Results The plasma levels of ET-1 ,ADM and CRP of decompensated heart failure group were significantly higher than the compensated cardiac function group;In the decompensated heart failure group,the plasma levels of CRP and ADM were elevated according to worsening of heart failure(NYHA classification) ;In the decompensated heart failure group,the plasma levels of CRP were positively correlated with ADM(r=0.57).Conclusion There is extensive activation of cytokines,ADM and ET-1 in patients with chronic congestive heart failure.Cytokine activation might play a role in the synthesis of ADM,thus contribute to the hum oral regulation of heart failure,but may not be re- sponsible for the activation of ET-1.

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

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.

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 explore the change of hippocampal neurons cholinergic receptor in rats with vascular dementia(VD).Methods VD rat models were established by employing improved method of Pulsinelli's four-vessel occlusion.1 month later,the abilities of learning and memory of VD models were tested by Morris water maze.The activities of acetylcholinesterase (AChE) in plasma and hippocampus were detected by the improved Ellman's colorimetric methods.The expressions of hippocampal nicotinic acetylcholine receptor (nAChR) subunits ?3,?4 and ?7 proteins and mRNA were detected respectinely by Western Blotting and RT-PCR,respectively.The results were compared with sham operation group.Results Compared to the sham operation group,the escape latency of Morris water maze test and the first time crossing platform in VD group were significantly prolonged,the number of crossing platform was decreased (all P

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.
