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.

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.

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

AIM To investigate the feasibility of bacterial endotoxins test for cisplatin injection. METHODS Gel clot and kinetic turbidimetric limulus tests were applied. RESULTS After diluted to 0 14 g?L -1 ,six batches of cisplatin injection didn't interfere with the test for bacterial endotoxins, others except three also didn't interfere with the test at the concentration of 0 28 g?L -1 ; The content of bacterial endotoxins in all samples tested was not more than 1 8 ZU?g -1 . CONCLUSION The kinetic turbidimetric limulus test provides a new way to detect the content of endotoxins in cisplatin injection, samples can be diluted to 0 14 g?L -1 to refute their interfering effects on routine bacterial endotoxins test.

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 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.

At first,this paper introduces a kind of sickbed desk,which can be manipulated easily,and patients could live more comfortable with it.Secondly,it introduces universal lamp holder.Different light sources are used in different medical equipments and the connection of their bulbs and lamp holders are different,too.These lamp holders are expensive and apt to be damaged.In order to prolong the using time of the chilly light,and reduce the spoilage and cost,this paper designs an economic and durable universal lamp holder.
