AimTo study the effect of extracts of ginkgo biloba leaves(GbE) on apoptosis in neuronal cells. Methods Primary cerebral cultures from rat fetus were used to observe the activity of neuronal cells and to determine the release of LDH and DNA gel electrophoresis. Results Gb E enhanced the activity of neuronal cells, decresed the release of LDH,and relieved the structural changes of nucleus and DNA fragmentation. Conclusion GbE can inhibit apoptosis in neuronal cells.

Aim To study the protective effects of bFGF on rats’ renal tubular epithelial cells injured by gentamicin in vitro.Methods After renal cortexes were grinded,filtered and digested with 0.25% trypsin,renal tubular epithelial cells were cultured.The cell types of epithelial cells were identified by cytokeratin 18 immunocytochemistry.The injury models of epithelial cells of renal tubules were established by gentamicin and then the protective roles of bFGF on injured renal tubular epithelial cells were observed. Results ①By observing the morphology of the epithelial cells and identifying the cell types with cytokeratin 18 antibody,comparing GM group with control group,CAT,Na+,K+-ATP enzyme activity decreased,while NAG activity and MDA level increased(P0.05),but the differences of MDA was still significant(P

Aim To study the effects of extract of astragalus on hippocampal delayed neuronal death of totalcerebral ischemia and 7 days reperfusion in rats.Methods Global ischemia was made by four-vessel occlusion. Electron microscope was used to observe the ultramicrostructure of dorsal hippocampal neurons.Light microscope was used to survey the structure of hippocampal neurons and to count the number of normal neurons in CA1 sector. Glial fibrillary acidic protein(GFAP) was detected by immune histochemistry.Results Compared with ischemia and reperfusion group(I/R),EA improved the ultrastructure of hippocampal neurons, suppressed the decrease of normal neurons in CA1 and degraded the expression of GFAP .The number of normal neurons in I/R group was 38?11.5,and in EA(20,40 mg?kg -1) groups,63?12.8(P

Aim To study the mechanisms of protective effects of extract of astragalus against focal cerebral ischemia/reperfusion injury in rats. Methods Focal cerebral ischemia was induced by intraluminal thread occlusion of middle cerebral artery. Immunohistochemistry was used to determine expression of TNF-?,IL-1? was measured by radioimmunity, and the apoptosis was observed by TUNEL. Results EA(20、40、80 mg?kg -1,ig)could decrease the expression of TNF-? and the level of IL-1? and reduce cell apoptosis. Conclusion EA has inhibitory action on the increase in the expression of TNF-?,the level of IL-1? and the apoptosis of neurons induced by focal cerebral ischemia/reperfusion.

Objective To observe the clinical efficacy of thread embedding at the holographic point Kidney of the second metacarpal bone in treating tinnitus.Method Eighty-two patients with tinnitus were randomized into a treatment group and a control group, 41 cases in each group. The treatment group was intervened by thread embedding at the holographic point Kidney of the second metacarpal bone, while the control group was by intragluteal injection with Mecobalamin 0.5 mg. The Tinnitus Handicap Inventory (THI) was compared before intervention and after 1 treatment course.Result The THI scores were significantly changed in both groups after intervention (P<0.01). The change of THI score after intervention in the treatment group was significantly different from that in the control group (P<0.05).Conclusion Thread embedding at the holographic point of the second metacarpal bone in an effective approach in treating tinnitus.

Objective To investigate the prognostic value of heart rate turbulence (HRT) in patients with chronic heart failure (CHF). Methods From October 2006 to May 2009, a total of 96 elderly CHF inpatients were selected, and the clinic data were recorded. Based on the echocardiogram and dynamic electrocardiogram, the differences of sinus HRT index of patients with different cardiac function classification were analyzed. During 9-28 months medical follow-up, the treatment endpoint was death from heart disease. Based on Logisitc regression, the prognostic values of HRT, age, hypertension, diabetes, myocardial infarction (MI), left ventricular ejection fraction, ACEI and β- adrenergic blocker for death of CHF patients were analyzed.Results There was no significant difference in HRT between grade Ⅱ and grade Ⅲ cardiac function (χ~2 = 1.60, P>0. 05), and between grade Ⅲ and grade Ⅳ cardiac function (χ~2 = 1.43, P>0. 05). But there was significant difference in HRT between grade Ⅱ and grade Ⅳ cardiac function patients χ~2 =9.84, P<0. 05), and HRT was weaken in grade Ⅳ group. The average follow-up time was (18. 0±9.6) months. Of all 96 patients, there were 34 dead of heart disease. There were correlations of death of CHF with HRT, low LVEF (≤ 45%), age (≥65 years), diabetes, MI and classification of heart function. Conclusions The sinus HRT in CHF patients has a favorable prognostic value.

Objective To evaluate in vivo tracking of swine mesenchymal stem cells (MSCs) la-beled with super paramagnetic iron oxide (SPIO) in intraportal transplantation by a clinical 1.5T MR.Methods MSCs were isolated from swine and cultured as well as expanded, which were then incuba-ted with SPIO (Feridex I. V.). Prussian blue staining was performed for showing intracelluar irons.To establish a swine model of acute liver necrosis, 0.5 g/kg of D-galactosamine was administrated to 10 pigs. MSCs(labeled cells in six, unlabeled cells in four)were injected into liver via portal veins. MR imaging was performed with a clinical 1.5T MR immediately before and at 6 h, 3 d, 7 d, 14 d after transplantation, respectively. Results Prussian blue staining of SPIO labeled MSCs could be effec-tively labeled and the labeling efficiency was almost 100%. Signal intensity loss in liver by SPIO labe-ling on FFE sequence persisted until 14 days after transplantation. Histological analysis by Prussian blue staining showed homing of labeled MSCs in liver after 14 days, primarily distributing in hepatic sinusoids and liver parenchyma. Conclusion MSCs can be labeled with SPIO in vitro successfully.MRI can monitor magnetically labeled MSCs transplanted into liver.
