Objective To explore the serum lactic acid,transaminase and their relationship with liver pathological damage in sepsis rats,whether a correlation exists between serum lactate clearance rate and transaminase in sepsis rats,and whether they can be used as indicators for the prediction and evaluation of septic rats liver injury.Methods A total of 150 clean Sprague-Dawley (SD) rats was divided into normal group (n =50),sham operated group (n =50),and the cecal ligation and puncture (CLP) (n =50).Ten rats were killed after successful surgery at the 6th,12th,24th,48th,and 72nd hour in CLP group,respectively.At each time point,10 normal rats and 10 sham-operated rats were taken as a control in the corresponding time point.The liver tissue was obtained for pathological analysis.The levels of lactate and liver transaminase were detected and the lactate clearance rate was calculated.The levels of lactate and transaminase at each time point were statistically compared.The correlation analysis was performed among serum lactate,transaminase,and liver damage pathological changes.Results The rat hepatocytes in CLP group begin to appear at the 6th hour,and the damage was gradually enhanced at the 12th,24th,and 48th,and up to the worst damage at the 48th time point.The levels of lactate and alanine aminotransferase (ALT)in CLP group at the 12th and 24th hour were significantly elevated compared with the normal and sham operation groups (P ＜0.05); The level of aspartate aminotransferase (AST) in CLP group at the 6th,12th,24th,48th,and 72nd hour was significantly elevated compared with the normal and sham operation groups (P ＜ 0.05).A positive correlation was found between the levels of ALT and lactate (r =0.766,P ＜0.05),and a negative correlation was found between lactate clearance rate and ALT (r =-0.712,P ＜0.05).Conclusions In septic rats,both lactate and lactate clearance rate were correlated with ALT,and they were correlated with liver pathological damage.The level of lactate,lactate clearance rate,and ALT could be used as the key indicators to predict liver damage in septic rats.

This paper reviewed the award of the title for senior professional post from four aspects: changing process of the technical post title enforcement efficiency, characteristic and problem, in Tianjin Medical University General Hospital in recent eight years. It was indicated that the new evaluation of high ranking professional title played a rule in inspiring and leading effect on the teaching and research of the hos-pital.

Objective To investigate the chemical constituents in the whole plant of Clerodendrum canescens. Methods The compounds were isolated by column chromatography over silica gel or Sephadex LH-20 gel and their structures were elucidated by chemical and spectroscopic methods. Results Seven triterpenoids were isolated and identified as: lupeol (Ⅰ), ?-amyrin 3-undecanotate (Ⅱ), lupeol acetate (Ⅲ), lupeol 3-palmitate (Ⅳ), melastomic acid (Ⅴ), ?-amyrin acetate (Ⅵ), betulinic acid (Ⅶ), respectively. Conclusion Among those compounds, compound Ⅱ is a new one, while compounds Ⅳ-Ⅵ are isolated from the plants of Clerodendrum Linn. for the first time.

Abstract BACKGROUND:Previous studies have found that cryptotanshinone represses multiple tumors, but little is reported on its effect on renal carcinoma. OBJECTIVE:To explore the effect of cryptotanshinone on the proliferation and apoptosis of the renal carcinoma stem cels. METHODS:CD133+ renal carcinoma stem cels were separated from OS-RC-2 cels by immunomagnetic bead separation. Effects of 0, 0.2, 1, 5 mg/L cryptotanshinone on the proliferation and apoptosis of CD133+ renal carcinoma stem cels were detected by MTT and flow cytometry, respectively. Expression levels of Ki67, Bcl-2, Caspase-3 and p-Caspase-3 protein were detected by western blot assay. RESULTS AND CONCLUSION:After magnetic cel sorting, the percentage of CD133+ cels was increased from 6.32% to 82.73%, and there was a significant difference before and after cel sorting (P < 0.001). Cryptotanshinone could repress the proliferation of CD133+ renal carcinoma stem cels and promote cel apoptosis in a dose-dependent manner. The protein expression levels of Ki67 and Bcl-2 in the 5 mg/L cryptotanshinone group were significantly decreased compared with the control group, while the protein expression level of p-Caspase-3 protein was significantly increased. In addition, there was no difference in the protein expression of Caspase-3 between cryptotanshinone and control group. These findings indicate that cryptotanshinone may be a potent anticancer drug for the treatment of renal carcinoma by inhibiting expression of Ki67 and Bcl-2 and promoting protein expression of p-Caspase-3.

Objective To observe the effect of motor relearning program (MRP) on balance function of stroke patients.Methods Sixty stroke patients were randomly divided into the MRP group and control group with 30 cases in each group. The patients of the control group were trained with proprioceptive neuromuscular facilitation (PNF) therapy; those of the MRP group were trained with the MRP therapy. The balance function of all patients was assessed with the Fugl-Meyer Balance Function Assessment before and after training.Results After training, the scores of Fugl-Meyer Assessment of all patients increased ( P<0.05), but scores of the patients of the MRP group were significantly higher than that of the control group ( P<0.05).Conclusion The MRP training can improve the recovery of balance function of stroke patients.

Aim To establish a mouse model of AIDS and observe the effects of Combivir,an anti-AIDS drug.Methods The model was set up by infecting infant mice with L6565 murine leukemia virus.Quantitative RT-PCR method was used to measure viral load in plasma.The percentage of CD4~+ and CD8~+ lymphacytes was estimated by flowcytometric method.The number of WBC,RBC and marrow karyote was counted.indexes of immune organs were weighed and calculated.Results Compared with control,the viral load in plasma in the model was at high level.The percentage of CD4~+ lymphocyte,the ratio of CD4~+/CD8~+,the number of RBC and marrow karyote,and thymus index were significantly decreased in the model,while the number of WBC and spleen index was remarkably increased.Conclusion AIDS patient symptom is shown in mouse infected with L6565 murine leukemia virus.This suggests that this model is likely to be used as a mice model to evaluate the effect of anti-AIDS drugs.

Patent ductus arteriosus(PDA) is a common condition that primarily occurs in preterm infants who with low birth weight,which closely related to several co-morbidities(intracranial hemorrhage,necrotizing enterocolitis,pulmonary edema/hemorrhage,bron chopulmonary dysplasia,and retinopathy).Although the color Doppler ultrasound assessment can be used as the gold standard to determine the present of PDA,it is still very hard to fully reflect the hemodynamic change occured in PDA case.In recent years,B-type natriuretic peptide (BNP) and N-terminal pro-brain natriuretic peptide (NT-proBNP),two kind of biological markers,were used in the premature infants to assess the present,shunt volume,progress and durg or surgical intervention indication of PDA.In this paper,the corrections of PDA between BNP and NT-proBNP were reviewed briefly.

Nonalcoholic fatty liver disease (NAFLD)is prevalent in patients with characteristics of metabolic syndrome.The main clinico-pathological manifestations of NAFLD are fatty degeneration of liver parenchyma cells and fat storage,which can progress to liver cirrhosis and eventually lead to liver failure.Toll -like receptor 4 (TLR4)signaling pathway is involved in the development and progression of NAFLD.At present,the role of TLR4 in the onset of NAFLD is highly valued by clinical doctors.This paper reviews the structure of TLR4, the composition of TLR4 signaling pathway,the regulation of TLR4 expression,the function of TLR4,and the relationship between TLR4 and NAFLD,suggesting that TLR4 signaling pathway is going to be an important research field in the treatment of NAFLD in the future.
