Objective To observe the expression of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) in the hippocampi of rats stressed by restraint,and adjustments to 11β-HSD1 expression in response to electroacupuncture.The mechanisms of adjustment of the hypothalamic-pituitary-adrenal axis(HPA) to electroacupuncture were also studied.Methods Rats were randomly divided into a control group,a group stressed by restraint and an electroacupuncture group.The rats in the control group received no treatment. The rats in the strssd group were put into a small columnar cage and their hind legs tied outside the cage. The electroacupuncture group, in addition to being restrained,received electroacupuncture at the Zusanli acupoints on both sides of their bodies. The rats were then sacrificed and their hippocampi were isolated and lysed. The expression of 11β-HSD1 in each hippocampus were observed using the Western blotting technique. Results The leves of expression of 11β-HSD1 in the hippocampi of the restrained group were significantly higher than those in the control group.After electroacupuncture,11β-HSD1 expression in the hippocampus increased further and lasted 3 h. Conclusion Electroacupuncture at the Zusanli acupoints (ST36) can increase 11β-HSD1 expression in the hippocampus of stressed rats, and this adjustment may be related to the HPA axis' negative feedback function.

Objective To conduct the clinical and pathological evaluation on the conservative surgery in tubal pregnancy . Methods 513 cases of tubal pregnancy in this hospital from January 2006 to December 2012 were divide into the conservative sur-gery group(A ,314 cases) ,samlpintectomy group(B ,43 cases) and the medication conservative treatment group (C ,156 cases) .The hospitalization days ,HCG negative-conversion time ,cure rate ,re-pregnancy outcome ,pregnancy during 1-year follow-up were com-pared between the group A and C .In group B ,43 cases of tubal pregnancy and accomplishing fertility were firstly performed the tubal linear incision in the pregnant site ,then the biopsy was conducted after stopping bleeding and finally the salpingectomy in af-fected side was performed .The tubal electric injury degree by the unipolar or bipolar electrocoagulation and the pathological changes under light microscope were observed .Results The hospitalization days ,symptom relief rate ,HCG negative-conversion time ,cure rate and re-pregnancy outcome had statistical differences between the group A and C (P<0 .05) .Conclusion The tubal conserva-tive surgery has short hospitalization time ,high symptom relief rate ,high cure rate and few complications .The pathological observa-tion shows the localized electrocoagulation injury .The pregnancy rate after surgery is high .

ObjectiveTo investigate the therapeutic effectiveness of defibrase in treating penumbra and reperfusion.MethodsIntraluminal suture method was used to develope reversible middle cerebral artery occlusion(MCAO). Rats were subjected to MCAO 3 hours followed by reperfusion for 3, 6, 24, 72 hours, and to MCAO 6 hours followed by reperfusion for 3, 6, 24 hours. The treatment groups rats were injected intravenously defibrase at 0.5 hour before reperfusion. Meanwhile, the control group received normal saline. Clinically Neurological Deficits Scale were evaluated every day. Infarction volume was measured by using 2,3,5-triphenyltetrazolium chloride staining. Pathologic change were examined microscopically in HE stained sections.ResultsThere were significant difference at treatment groups of reperfusion 3 hours after MCAO.Infarction volume and Clinically Neurological Deficits Scale was significant reduced as control group (P<0.05). There were no significant differences at treatment groups of reperfusion 6 hours after MCAO (P>0.05). Cerebral hemorrhage wasn't increased in defibrase treatment group.ConclusionsDefibrase was effective on Clinically Neurological Deficits of rats in reperfusion 3 hours after MCAO.

BACKGROUND:Gene therapy has become a new trend for disease therapy and brought promise for some refractory diseases. The key point is to choose the proper cell, gene and vector. OBJECTIVE:To investigate the effectiveness and feasibility of bone morphogenetic protein 2 (BMP2) gene transfected into endothelial progenitor cells (EPCs) from rat bone marrow for gene therapy. METHODS:The EPCs were isolated, cultured and identified from the bone marrow of Sprague-Dawley rats. Empty vector (LV-eGFP) or BMP2 gene (LV-eGFP-BMP2) was transferred into EPCs by the constructed lentiviral vector (LV). We examined the transfection efficiency by eGFP fluorescence, BMP2 secretion by ELISA, BMP2 expression by Western blot, and compared the capacities of migration, proliferation and anti-apoptosis after transfection in the three groups of normal EPCs, empty vector-EPCs, and BMP2-EPCs. RESULTS AND CONCLUSION:The transfection efficiency of lentiviral vector was 90%. BMP2 gene-transferred EPCs secreted and expressed more BMP2 proteins (P<0.01), and showed enhanced anti-apoptotic ability (P<0.05). The proliferation and migration capacity did not change obviously (P>0.05). After successful transfection with lentivirus-BMP2 gene, EPCs can secrete and express more BMP2 protein and show enhanced anti-apoptotic ability without obvious influence on the proliferation and migration capacity.
