Objective: To study the protective mechanism of Donepezil on apoptosis of PC12 cells induced by amyloid beta protein. Methods: PC12 cells were cultured as previously,then amyloid beta protein and Donepezil were used to treat PC12 cells.Morphology observation,TUNEL and immunocytochemistry were employed to investigate the damage of PC12 cells induced by A?,protection of Donepezil on apoptosis of PC12 cells and the expression of Bcl2 and Caspase-3 in A?-treated group and Donepezil-treated group. Results: A? induced apoptosis of PC12 cells in a dose-dependent way;Compared to the group treated with A? only and the group post-treated with donepezil, the apoptosis index of PC12 cells(17.29?0.83)% and expression of Caspase-3(26.46?2.87)% were significantly downregulated in the group pretreated with donepezil(P0.05). Conclusion: This study demonstrated that Donepezil can protect PC12 cells against apoptosis induced with amyloid protein,which was closely related to the time of interference.The mechanism of protection was involved with the expression of Bcl-2 and Caspase-3.

?Silent information regulator protein 1 ( SlRT1 ) is a kind of histone deacetylases class lll on which cell metabolism coenzyme NAD+ is dependent. By the transcriptional regulation, it participates in the regulation of gene transcription, energy metabolism and cell aging process, which can prolong the lifespan of organisms and delay the development of various age-related diseases and has attracted much attention in the field of anti - aging research. ln recent years, studies have shown that SlRT1 occupies an important position in the pathogenesis of many ophthalmic diseases, especially in ocular surface diseases, glaucoma, cataracts, uveitis, and ocular fundus diseases, etc. There is a possibility that the promotion of SlRT1 activity would be the new drug target of ophthalmic therapy. The paper will review studies on SlRT1 and ophthalmic diseases.

Objective To evaluate the factors which might affect the successful reopening of occluded subclavian artery. Methods During the period of Jan. 1998-March 2007, endovascular stent placement was performed in 20 patients with occluded subclavian artery, including 12 males and 8 females, aged 17-74 years (mean 53 years). The procedures were carried out by using super-slippery guide wire via anterograde or bilateral access. Results Successful reopening of occluded subclavian artery was obtained in 14 cases and the treatment ended in failure in 6 cases. In 14 patients with successful results, the mean length of diseased artery was 3.00 cm and the mean course of disease was 9.83 months, which were 2.13 cm and 27.6 months respectively in 6 cases of failure. The successful reopening rate was 80% in arthrosclerosis cases, while it was 50% in aorto-arteritis obliterans. The successful reopening rate was 100% in those cases whose occluded artery showing a sharp stump, while the successful reopening rate was 33% in those cases whose occluded artery showing a round stump, with a statistically significant difference between the two (P< 0.05). The successful rate in cases performed via anterograde access was 65%, and it was only 43% in cases performed via bilateral access. Conclusion The etiology, the duration of disease and the shape of stump bear a close relationship to the successful reopening rate, while no obvious correlation exists between the length of diseased artery and the reopening rate. Higher reopening rate can be achieved when the procedure is performed via anterograde access.

BACKGROUND:Tetramethylpyrazine (TMP) can inhibit the expression of vascular endothelial growth factor (VEGF), but it is uncertain that TMP inhibit the growth and proliferation of HL-60 leukemic cells induced by VEGF.OBJECTIVE:To observe the effect of TMP on the proliferation of HL-60 leukemic cells induced by VEGF.DESIGN:Repetitive measurement and observation.SETTING:School of Medicine, Wuhan University of Science and Technology.MATERIALS:The experiment was carried out in the Molecular Biology Laboratory Center, School of Medicine, Wuhan University of Science and Technology from March to June in 2007. Human leukemic cell line HL-60 cells were purchased from Shanghai Institute of Cell Biology. TMP hydrochloride injection was produced by Wuxi Seventh Pharmaceutical Products Limited (Lot number:011014), protamine sulfate injection was produced by Shanghai First Biochemical Pharmaceuticals (Batch number:010302), and immunohistochemistry kit was purchased from Boster company.METHODS:①Human leukemic cell line HL-60 cells at log phase were used for the experiments. Cells were treated with 100 μg/L VEGF, and then TMP at final concentrations of 1.5, 15, 150 mg/L was added into culture medium. While the cells in medium without TMP were taken as blank control group, and the cells in medium with 20 mg/L protamine as positive control group. Meanwhile cells without treatment of VEGF were served as VEGF control group. After cells were incubated for 48 hours, the growth inhibiting rate of HL-60 cells was detected by MTT assay.②After HL-60 cells were treated with TMP at the final concentrations of 1.5, 15, 150 mg/L for 24 hours, the protein expression of VEGF in HL-60 cells was examined by SP immunohistochemistry.MAIN OUTCOME MEASURES:①Growth inhibiting rate of HL-60 cells.②Protein expression of VEGF.RESULTS:①Growth inhibiting rate of HL-60 cells:After HL-60 cells induced by VEGF were treated with 15 and 150 mg/L TMP, the absorbance value was significantly lower than that in VEGF control group (P < 0.05).②Protein expression of VEGF:After HL-60 cells were treated with TMP for 24 hours, the protein expression of VEGF was down-regulated with increasing TMP concentration in a dependent manner. Significant differences were observed in the protein expression of VEGF between cells treated by TMP and the controls (P < 0.01).CONCLUSION:TMP can inhibit the proliferation of HL-60 cells stimulated by VEGF and down-regulate the expression of VEGF.

Epithelial-mesenchymal transition (EMT) is a process by which the epithelial cells change to a mesenchymal phenotype.The highly conserved and fundamental process is integral in development, wound healing and contributes pathologically to fibrosis and cancer progression.The process can be activated by many transcription factors, growth factors or protein molecules, which involves complex molecular mechanism and signal transduction pathways.This paper reviews the development of molecular mechanisms of epithelial-mesenchymal transition and briefly summarizes the research progress of natural compounds targeting the EMT.

Advanced-stage Hodgkin's lymphoma (HL) has become a curable disease in the majority of patients.ABVD is considered to be the standard therapy,but debates continue regarding the role of radiation therapy(RT)in this patient population. The incorporation of interim positron emission tomography (PET) imaging, and characterization of HL on cellular and molecular levels are emerging as tools for treatment stratification and predictors of disease status. Therapeutic advances over the past 3 decades have resulted in the cure of the majority of the patients with advanced-stage HL.Several questions have emerged when considering what constitutes optimal therapy with a balance between a high cure rate and minimizing shortand long-term toxicity.This review focuses on 3 key elements:what is the optimal chemotherapy? What is the role of radiation therapy(RT)in advanced HL? Can therapy based on clinical biological risk factors be adapted?

Objective To observe the distribution of TCM syndromes in patients with functional constipation (FC). Methods One hundred and five cases of patients with FC were analyzed with relevant factors and summarized to syndromes of FC by cluster analysis. Results There was a correlation between distribution of syndromes of FC and patient's age, job occupation, course of disease, incentives and patient's eating habits. The distribution of syndromes analyzed by cluster analysis was consistent with diagnostic criteria. Conclusion The syndromes of FC are divided into heat constipation, qi constipation, deficiency constipation and cold constipation. Among these syndromes, the number of excess constipation patients especially heat constipation is more than the number of others.

Objective To study the protective effect of recombination human erythropoietin (rhEPO) on the apoptosis of retinal neurons induced by glutamate.Methods The primary retinal neurons of postnatal SD rats were cultured in vitro for 7 days and divided into 3 groups :control group ,glutamate group and rhEPO pretreatment group.The neurons in the rhEPO pre-treatment group were afterwards allocated to three subgroups in terms of different rhEPO treatments (0.15 ,0.30 or 0.50 U/mL rhEPO for 12 h).Those in glutamate group and rhEPO pretreatment group were treated with glutamate at the concentration of 20μmol/L for 30 min for establishment of the apoptosis model.Twenty-four h later ,the apoptosis index (AI) was assayed by TUNEL and the expressions of BCL-xL mRNA and protein was detected by RT-PCR and immunocytochemistry respective-ly.Results The AI was significantly higher in the glutamate group than in the control group (P<0.01).The AI was signifi-cantly reduced ,and the expression level of BCL-xL mRNA and protein was markedly dose-dependently increased in the rhEPO pretreatment groups compared with the glutamate group (P<0.01).Conclusion The rhEPO pretreatment can inhibit the glu-tamate-induced apoptosis of retinal neurons by up-regulating the expression of BCL-xL .
