Aim To study the protective effects of sodium magnesium fructose diphosphate (FDPM) on the kidney in hemorrhagic shock rats. Methods The study utilized Wiggers hemorrhagic shock model. Sixty Wistar rats were divided into six groups randomly: normal saline control group,three doses of FDPM group (90.0,45.0,22.5 mg?kg -1 ),1,6-fructose diphosphate group(37.5 mg?kg -1 ) and magnesium sulfate group (3.4 mg?kg -1 ). Mean arterial pressure was monitored before shock, 10, 30 and 60 minuts after drug administration and 0, 30 and 60 minuts after shed blood reinfusion Blood urea nitrogen and creatinine, the content of malondiadehyde, and the activity of Na+-K+-ATPase, Ca 2+ -ATPase, Mg 2+ -ATPase, and superoxide dismutase in kidney were also measured. Results FDPM significantly improved mean arterial blood pressure of hemorrhagic shock rats, reduced blood urea nitrogen and creatinine, decreased the content of malondiadehyde and increased the activity of Na+,K+-ATPase,Ca 2+ -ATPase,Mg 2+ -ATPase and superoxide dismutase in kidney. Conclusion FDPM had protective effects on the ischemia-hypoxia injury of kidney by improving energy metabolism and attenuating tissue injury caused by free radicals in hemorrhagic shock.

ObjectiveTo investigate the effects of grape seed proanthocyanidin extracts (GSPE) on advanced glycation end product receptor (RAGE),NF-Κb and connective tissue growth factor (CTGF) in the myoeardium of diabetic rats.MethodsTotal 30 streptozotocin (STZ) induced diabetic rats were randomly divided into 2 groups:diabetic group (DM1,n-15) and GSPE (250 mg/ kg,i.g) treated diabetic group (DM2,n= 15).Another two control groups:normal rats(C1,n= 10)and normal rats treated with GSPE (250 mg/kg,i.g) (C2 group,n= 10) were also observed.After 24 weeks,blood was collected to measure fasting plasma glucose (FBG) and RAGE.The protein expression of NF-Κb was determined in myocardial tissue by immunohistochemical staining and Western blot.The protein expressions of RAGE and CTGF were measured by Western blot.Results The levels of FBG and RAGE were significantly higher in diabetic rats than in control rats (P＜0.05).After GSPE treatment,RAGE level significantly reduced (P＜0.05),but FBG had no change in diabetic rats.The protein expressions of RAGE,NF-Κb and CTGF in the myocardial tissue of diabetic rats had marked increase compared with control rats (P＜ 0.05),however,their levels significantly reduced after GSPE treatment (P＜0.05).ConclusionsGSPE may protect diabetic rats against cardiomyopathy,possibly by decreasing the protein expressions of RAGE,NF-Κb and CTGF.

Objective:To study the effect of Bcl-2 short hairpin RNA (shRNA) in enhancing methotrexate (MTX)-induced apoptosis of Raji cells. Methods:Expression plasmid containing Bcl-2 shRNA was transfected into Raji cells by lipofectmine 2000 and then the transfected cells were treated with MTX. The expression levels of Bcl-2 mRNA and protein were evaluated by RT-PCR and immunofluorescence method at 48 h of transfection. MTT assay was used to analyze cell proliferation at 24, 48 and 72 h. Apoptosis was detected by Giemsa staining and flow cytomertric cell cycle analysis. Results:After transfection with Bcl-2 shRNA, the expression levels of Bcl-2 mRNA and protein in Raji cells were significantly decreased (P<0.05). Bcl-2 shRNA transfection plus MTX treatment induced marked apoptosis, decreased in cell proliferation activity, and increased in apoptotic rate. The difference was significant compared with MTX group, negative shRNA plus MTX group, Bcl-2 shRNA group, and empty plasmid plus MTX group (P<0.05). Conclusion:Bcl-2 shRNA could enhance MTX-induced apoptosis and inhibition of cell proliferation in Raji cells.
