OBJECTIVE:To study the protective effect of the injection of puerarin combined with salvianoli acid B(Sal B)on rats with myocardial ischemia reperfusion injury (MIRI). METHODS:62 rats were randomly divided into sham operation group, model group,puerarin group(20 mg/kg)and puerarin(20 mg/kg)-Sal B group(mass ratio of 1:0.5,1:1,1:2,respectively),10 in each group. Except for sham operation group,rats in other groups were reduced for MIRI model. After 180 min of reperfusion, kinase(CK),lactate dehydrogenase(LDH),superoxide dismutase(SOD),malondialdehyde(MDA)in serum and percentage of myocardial infarction size of rats were detected. RESULTS:Compared with sham operation group,CK,LDH,MDA levels in se-rum of rats in model group were obviously increased (P<0.01),SOD level was obviously decreased (P<0.01);and percentage of myocardial infarction size was obviously increased (P<0.01). Compared with model group,CK,LDH,MDA levels in serum of rats in each administration group were decreased(P<0.05 or P<0.01),SOD levels were obviously increased(P<0.05 or P<0.01),and indexes changed the most obviously in puerarin-Sal B group(1:1);percentage of myocardial infarction size was obvi-ously decreased(P<0.01),and the percentage of myocardial infarction sizes in puerarin-Sal B group(1:1)and group(1:2)were less than Puerarin injection group (P<0.01). CONCLUSIONS:Compared with Puerarin injection alone,puerarin combined with Sal B by injection can more effectively inhibit the cardiomyocyte injury and decrease myocardial infarction size after MIRI,with best efficacy when quality ratio is 1:1.

Patients with ischemic stroke is often accompanied by inflammtory response. Studies have suggested that toll-like receptor 4 (TLR4) has induced the occurrence,development and of ischemic stroke and secondary brain injury. This article reviews the toil-like receptor 4 signal transduction pathway and its roles in ischemic stroke in order to provide certain basis for the development of TLR4-targeted medication.

Objective To explore the expression levels of RAS-interacting protein 1 (RASIP1) mRNA and protein in hepatocellular carcinoma (HCC) tissues and its cell lines,and to analyze the relationship between RASIP1 and tumorigenesis and progression of hepatocellular carcinoma.Methods The expression levels of RASIP1 mRNA and protein in 29 hepatocellular carcinoma tissues and the corresponding adjacent non-cancer liver tissues (ANLTs),as well as those in the HCC cell lines such as LO2,HEPG2,MHCC97-H and HCCLM3 were detected using real-time PCR and western blot.Results The RASIP1 expression levels decreased significantly in HCC tissues when compared with the corresponding ANLTs; The expression levels of RASIP1 mRNA and protein in LO2 were significantly higher than those in other HCC cell lines (P ＜ 0.05) ; The expression levels of RASIP1 mRNA and protein in MHCC97-H and HCCLM3 were significantly lower than those in HepG2 (P ＜ 0.05).Conclusions HCC tissues had lower expression than those in ANLTs.On analyzing the RASIP1 levels of HCC tissues and its cell lines,we speculated that RASIP1 might suppress recurrence and metastasis of HCC.

Objective To investigate the effect of percutaneous vertebroplasty and kyphoplasty (PKP) on bone density and serum leptin in patients with osteoporotic thoracolumbar compression fractures. Methods One hundred and two patients with osteoporotic thoracolumbar vertebral compression fractures and 100 cases of healthy control were treated with PKP surgery. The serum leptin and adiponectin, and the bone mineral density of the lumbar spine were determined. Results patients Levels of the serum leptin and adiponectin in patients with osteoporotic thoracolumbar vertebral compression fracture were significantly higher than those with non osteoporotic fracture patients (P < 0.05). One month post-PVP, the levels of serum leptin and adiponectin in the two groups were significantly decreased (P < 0.05). postoperative group of The lumbar bone density at 1 month post-operation was is significantly higher than that before operation in each group (P < 0.05, respectively), with no significant difference between the two groups. The levels of serum leptin and adiponectin were negatively correlated with the bone mineral density (BMD) (P < 0.05). Conclusions tLevels of serum adiponectin and leptin were both increased in osteoporotic or non bone osteoporosis thoracolumbar vertebral compressor fractures. The percutaneous vertebroplasty forming operation could effectively reduce the serum level of leptin and adiponectin, and improve the bone mineral density of the lumbar vertebrae.
