Hyperglycemia has been identified as one of the important factors involved in the microvascular complications of diabetes, and has been related to increased cardiovascular mortality. Endothelial damage and dysfunction result from diabetes; therefore, the aim of this study was to determine the response of endothelial cells to stressful stimuli, modelled in normal and high glucose concentrations in vitro. Eahy 926 endothelial cells were cultured in 5 mmol/L or 30 mmol/L glucose conditions for a 24 hour period and oxidative stress was induced by exposure to hydrogen peroxide (H2O2) or tumour necrosis factor- α (TNF- α ), following which the protective effect of the glucocorticoid dexamethasone was assessed. Apoptosis, necrosis and cell viability were determined using an ELISA for DNA fragmentation, an enzymatic lactate dehydrogenase assay and an MTT assay, respectively. High glucose significantly increased the susceptibility of Eahy 926 cells to apoptosis in the presence of 500 μmol/L H2O2, above that induced in normal glucose (P<0.02). A reduction of H2O2- and TNF- α -induced apoptosis occurred in both high and low glucose after treatment with dexametha-sone (P<0.05). Conclusion high glucose is effective in significantly augmenting stress caused by H2O2, but not in causing stress alone. These findings suggest a mechanism by which short term hyperglycemia may facilitate and augment endothelial damage.

Objective:To explore the influence of infusion drop speed on the efficacy of tiopronin for injection combined with sol-vents in the treatment of abnormal liver function. Methods:Totally 74 patients were randomly divided into the observation group and the control group with 37 ones in each. The infusion drop speed was 60-65 drops per minute in the observation group, and that was 30-35 drops per minute in the control group, and the infusion time was controlled in 1h in the observation group and 2h in the control group. The clinical effect and the improvement of liver function were compared between the two groups after a treatment course of 4 weeks. Results:The total effective rate of the observation group(83. 78%) was obviously higher than that in the control group(56. 76%) (P<0. 05) after the treatment, and ALT, AST and TBIL of liver function indices were improved obviously except for ALB in the two group, and the difference was statistically significant between the two groups(P<0. 05). Conclusion:Tiopronin for injection can effectively improve the clinical effect by strictly controlling the time and drop speed of infusion.

Objective To compare the accuracy of diagnostic peritoneal lavage (DPL),abdominal computed tomographic(CT) scanning,and abdominal B ultrasound for the diagnosis of blunt abdominal trauma. Methods Prospective study was made on 61 hemodynamically stable abdominal injury patients.The patients received both CT and B ultrasound before DPL ,A laparotomy was done on the condition that one of the three examinations had positive finding.The surgical findings were compared with that of the diagnostic studies. Results The sensitivity,specificity and accuracy were 97.4%,81.7% and 91.8% for DPL; 97.3% 91.3% ,and 95.1% for CT;and 92.3%,90.9% and 91.8% for B ultrasound.Although the sesitivity,specificity,and accuracy of B ultrasound in the diagnosis of blunt abdominal trauma were similar to DPL and CT, B ultrasound had more advantages than DPL and CT. Conclusions B ultrasound can replace DPL.CT as a supplementary method in the diagnosis of blunt abdominal trauma.

Objective The aim of this study was to determine if isoflavone genistien has protective effects against high glucose-induced cell apoptosis in human aortic endlthelial cells,and investigate the possible mechanism for this protection.Methods Human aortic endothelial cells subjected to normal (5mmol/L) or high glucose (25mmol/L) were treated with genistein at 0,50,100nmol/L.Parallel experiments were performed with 100nM 17b-estradiol,and also in the presence and absence of the pure anti-estrogen ICI-182,780 (100nmol/L).The effects on cell apoptotic DNA fragmentation were determined using cell death ELISA,and the effects on cellular proliferation were determined using tritiated thymidine incorporation assay.Estrogen receptor expression was detected by Taqman quantitative PCR.Results Genistein at 100nmol/L significantly reduced high glucose-induced DNA fragmentation,and reversed cell DNA synthesis inhibition (P＜0.001) after 24 hours' incubation.The effect of genistein was completely blocked by ICI-182,780administration.Estrogen receptor beta,but not alpha was found to be expressed in these cells.Conclusion Isoflavone genistein shows protection against high glucose-induced cell damage through estrogen receptor beta,reducing apoptotic DNA damage and protecting from the inhibition of cell proliferation.

To study the anti-inflammatory activity of glycyrrhizin acid, ligustrazine and puerarin. In the study, the liquichip-based high-throughput synchronous detection technique for 23 inflammatory factors, uniform design, comprehensive weight method were adopted to study the effect of different combined administration of glycyrrhizin acid, ligustrazine and puerarin in inhibiting the expression of lipopolysaccharide (LPS)-induced RAW264. 7 cells and multiple inflammatory cytokines. In the study, the uniform design table U₉ (9³) was adopted to design doses of glycyrrhizin acid, ligustrazine and puerarin. The liquichip technique was used to detect the effect of different combined administration of glycyrrhizin acid, ligustrazine and puerarin on the 23 cytokines expressed in LPS-induced mouse macrophage RAW264. 7 inflammation model. The traditional Chinese medicine component optimization software and the improved least angle regression algorithm were used to analyze the dose-effect relationship among the three components and the cytokine inhibition rate and produce the regression equation. The comprehensive weight method was applied to get the optimal dose ratio of glycyrrhizic acid, ligustrazine and puerarin with highest efficacy of 25:2:13 and verify the optimal dose ratio. The verification results were consistent with the prediction trend, indicating the accuracy of the mathematical model for predicting the experiment. The experimental results showed the multi-target and multi-level efficacies of glycyrrhizic acid, ligustrazine and puerarin and the high anti-inflammatory activity of their combined administration, which provides powerful basis for subsequent drug development.
