The human brain-derived neurotrophic factor (hBDNF) gene was cloned by polymerase chain reaction and the recombinant adeno-associated viral vector inserted with hBDNF gene (AAV-hBDNF) was constructed. Cultured rat hippocampal neurons were treated with Abeta(25-35) and serued as the experimental Abeta-induced neuronal damage model (AD model), and the AD model was infected with AAV-hBDNF to explore neuroprotective effects of expression of BDNF. Cell viability was assayed by MTT. The expression of bcl-2 anti-apoptosis protein was detected by immunocytochemical staining. The change of intracellular free Ca ion ([Ca2+]i) was measured by laser scanning confocal microscopy. The results showed that BDNF had protective effects against A-induced neuronal damage. The expression of the bcl-2 anti-apoptosis protein was raised significantly and the balance of [Ca2+]i was maintained in the AAv-hBDNF treatment group as compared with AD model group. These data suggested that recombinant AAV mediated a stable expression of hBDNF in cultured hippocampal neurons and resulted in significant neuron protective effects in AD model. The BDNF may reduce neuron apoptosis through increasing the expression of the bcl-2 anti-apoptosis protein and inhibiting intracellular calcium overload. The viral vector-mediated gene expression of BDNF may pave the way of a novel therapeutic strategy for the treatment of neurodegenerative diseases such as Alzheimer's disease.

Objective To investigate the influence of psychological intervention on the urodynamic test. Method The 959 patients in the urodynamic test were divided into two groups:the control group and the the test group,then we analyzed and compared the results. Results In the incidence of the abnormal abdominal pressure, the unnatural detrusor contraction and the Unnatural urethral sphincter contraction, there were statistically significant differences between two groups ( <0.05) . Conclusion It effective and necessary for urodynamic test to do psychological intervention.

Objective To study the level of cyclooxygenase-2 (COX-2) and platelet-activating factor acetyl-hydrolase(PAF-AH) and high sensitive C reactive protein(hsCRP) on peripheral blood mononuclear cells in Acute Coronary Syndrome(ACS) patients and the effect of atorvastatin on them and the clinical significance. Methods To measure and compare the content of COX-2,PAF-AH and hsCRP in normal control group and ACS group(before and after treatment). Result The content of COX-2,PAF-AH and hsCRP are significantly different between normal con-trol group and ACS group (before treatment) (P < 0.05), and between ACS group (before treatment) and ACS group (after treatment) too(P < 0.05). Conclusions The inflammatory cytokines COX-2,PAF-AH and haCRP have sig-nificant correlation with the occurance of ACS. Atorvastatin can decrease COX-2 and hsCRP level, and can increase PAF-AH level. So atorvastatin takes an important role in lessening inflamatory reaction level in ACS patients.

Objective To investigate the expressions and clinical significanees of suppressors of cytokine signaling-1 (SOCS-1) and SOCS-3 in myocardium of patients with sudden cardiac death (SCD). Method This study included myocardial autopsy specimens of 24 patients admitted between 2005 and 2006. Of them, 9 cases had the findings of autopsy examination consistent with coronary atberosclerosis (non-myocardial infarction) leading to SCD (non-MI group), 7 patients died of acute myocardial infarction (MI group) and 8 patients died of traffic accidents and trauma The expressions of SOCS-1 mRNA and SOCS-3 mRNA in the myocardium of non-MI and con-trol group were detected by using RT-PCR. The levels of SOCS-1 protein and SOCS-3 protein were detected by us-ing immunohistochemistry. Statistical analysis were performed by using SPSS version 13.0 software and the data were processed with ANOVA test. Results The expressions of SOCS-1 mRNA and SOCS-3 mRNA in non-MI and MI groups were were significantly higher than those in control group (0. 788±0. 101) and (0. 741±0.111) vs.(0.436±0.044) (P <0.01); (0.841±0.092) and (0.776±0.070) vs.(0.454±0.076), P <0.01, re-spectively). The antibody-positive cells of SOCS-1 protein in myocardium of non-MI group and MI group were significantly higher than those in myoeardium of control group (320.00±48.48) and (347.14±70.88) vs.(42.50±10.35) (P < 0.01), respectively. The antibody-positive cells of SOCS-3 protein in myoeardium of non-MI group and MI group were significantly higher than those in myocardium of control group (381.11±59.25) vs.(40.00±10.69), (P < 0.01)and (332.86±111.91) vs. (40.00±10.69), (P =0.001). Conclusions The expressions of SOCS rnRNA and SOCS-3 mRNA in myoeardium of patients with SCD from coronary diseases are significantly increased contributing to the pathogenesis of SCD.
