Objective To observe the expressions of vascular endothelial growth factor(VEGF) and cyclooxygenase-2(COX-2) in the cerebral tissue following hypoxic-ischemic encephalopathy(HIE) in newborn rats and explore the machanism of inosine in protecting against hypoxic-ischemic brain damage(HIBD).Methods Sixty-six newborn rats aged 7 days were divided into sham,control and experimental groups.HIE models were made by clamping the right cervical artery and making hypoxia for 2 hours.The rats in experimental group began injecting inosine,at 1 day before experiment,and the rats in the sham and control groups saline solution with same dose.The samples were made at the given time,and expressions of VEGF and COX-2 were investigated by immunohistochemical technique.Results The cerebral tissue had no expression of VEGF and COX-2 in sham group.From 2 hours on cortex and striatum after HIE in control and experimental groups,expressions of VEGF and COX-2 increased rapidly,peaking at 12-24 hours,and then decreased gradually.Expressions of VEGF and COX-2 were higher in experimental group(All P

Objective To explore the expressions of transforming growth factor(TGF)-?1 and connective tissue growth factor(CTGF) in viral myocarditis(VM) and the intervention effect of valsarta on them.Methods Fifty-four male Balb/c mice were randomly divided into 3 groups:control group,treatment group and model group.Model group and treatment group established VM model by intraperitoned injecting 0.1 ml CVB3.They were killed on days 7,14 and 28,respectively.Histological cross sections of heart were stained with hematoxylin-eosin and myocardial histopathplogic scores were counted under optical microscope.The expressions of typeⅠand Ⅲ myocardial collagen,TGF-?1 and CTGF were examined by immunohistochemical method and analyzed by using SPSS 11.5 software.Results Compared with control group,histopathplogic scores,the expressions of type Ⅰand Ⅲ myocardial collagen,TGF-?1 and CTGF increased markedly in model group (Pa

The treatment of cerebral palsy is still a big medical problem.The pathogenesis of spasticity,as result of a variety of lesions of the cerebral cortex,brain stem,spinal cord,is caused by involvement of the inhibitory pyramidal and parapyramidal descending tracts terminating on the spinal facilitatory myotatic reflex.A lesion of the descending tracts disturbs this equilibrium leading to spasticity,which is cha-racterized by muscle resistance at rest that is velocity dependent and associated with an increase in tonic stretch reflexes resulting from hype-rexcitability of the stretch reflex.Spasticity caused abnomal posture,caused special movement,and higher multilation,which affect children's life severely.There are so many ways to lower hypermyotonia,such as:drugs,rehabilitation care,acupuncture and so on.Bioelectric stimulation therapy is a new ways in the zone.Its curative effect and the mechanism are still in explore,this article just to give an overview about bioelectric stimulation therapy in curing spastic cerebral palsy.

Diabetic diarrhea is one of the chronic complications of diabetes, which is particularly closely related to the spleen and kidney. Using these two organs as the theoretical foundation, the root of diabetic diarrhea can be grasped. Pathogenic dampness is responsible throughout the whole process of diabetic diarrhea. Using syndrome differentiation, deficiency is as the basic pattern and excess is the syndrome for diabetic diarrhea; diagnosis and treatment combine symptoms and syndromes, which not only particularly pay attention to protecting the spleen and kidney, but also clearing pathogenic dampness. At the same time, flexible medication is applied according to dynamic symptoms, which can achieve good efficacy.

The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.

Objective To study the interventional effects of Candesartan Cilexetil on vascular endothelial function and expres-sions of ERK/CREB signaling pathway in rats with acute myocardial infarction.Methods 30 rats were randomized into CAN group,AMI group and Sham group.Two weeks after the treatment rats were sacrificed and blood pressure,levels of blood AngⅡ, NO and NOS,endothelial vasomotor effects of isolated thoracic aorta strips,myocardial infarctual area and the expressions of ERK mRNA and CREB mRNA in infarctual myocardium were explored.Results Blood AngⅡ levels were distinctly higher in AMI group when compared with the Sham group,while the NO and NOS level were much lower.accompanied with EDDs decreased seri-ously,and higher mRNA expressions of ERK1 and CREB in infarctual myocardium.All of the above differences were significant. After the treatment of Candesartan Cilexetil,levels of serum NO and activities of NOS were obviously higher and almost reached the similar levels to those in Sham group,additionally endothelium-dependent diastole in isolated aortic strips improved greatly.Mean-while Candesartan Cilexetil can not only increase the plasma AngⅡ,but also decrease the size of myocardial infarction and the mR-NA expressions of ERK1 and CREB in infarctual myocardium significantly.However,blood pressure in all groups was not affected. Conclusion Candesartan Cilexetil can greatly improve the disordered endothelial function developing post-AMI,decrease the size of myocardial infarction and down-regulate the mRNA expressions of ERK and CREB in myocardium of infarctual zone.And all of the above protective effects of Candesartan Cilexetil were independent on blood pressure lowering.

Objective To evaluate the efficacy and safety of sorafenib in the treatment of advanced renal cell carcinoma.Methods The clinical date of 33 patients with advanced renal cell carcinoma from September 2007 to April 2012 was reviewed retrospectively.26 were males and 7 were females,with an average age of 69 years.Pathological diagnosis showed 30 clear cell RCCs,2 papillary RCCs,and 1 unclassified RCC.These patients were treated by sorafenib 400 mg twice a day until intolerable toxicity or disease progression.The primary end points were objective response rate,clinical benefit rate,median survival time,median progression-free survival and the incidence of adverse reaction.Results All patients were evaluable for response and toxicity,with 8 patients (24％) of partial remission,19 cases (58％) of stable disease,and 6 cases (18％) of disease progression.The disease control rate was 82％,the median progression-free survival was 10.2 months,while the median survival time was 16.5 months.The common adverse reactions included hand-foot skin reaction (61％),diarrhea (46％),hypertension (21％).Most adverse reactions occurred around the second week after drug therapy,with the duration unequal.The majority of adverse reactions could be released by symptomatic treatment,which did not affect the medication.Conclusion Sorafenib has good short term efficacy for patients with advanced renal cell carcinoma,and most adverse reactions were tolerable.
