Objective: To study the protective effect of anti-tumor necrosis factor-?antibody (TNF-? Ab) on lung injury after cardiopulmonary bypass(CPB). Methods: 20 patients with valve diseases underwent valve replacement under CPB. The patients were randomly divided into two groups: control group and TNF-? Ab group. In the TNF-? Ab group, human TNF-? Ab was dropped into the intracheal tube before operation and just after releasing the aortic clamp, respectively. Lung dynamic compliance, blood neutrophils count and TNF-? from the right and left atrium were determined perioperatively. Results: The dynamic compliance of the lung in TNF-? Ab group was higher than that in control group. TNF-? Ab can reduce releasing of TNF-? and restrain leukocyte accumulation in the lung. Conclusion: TNF-? Ab has markedly protective effect on lung injury after CPB.

Objective To explore the effects of telmisartan on expression of peroxisome proliferators PPARs activated receptors and adiponectin receptor 2 in rats with nonalcoholic steatohepatitis (NASH).Methods Forty male SD rats were randomized into normal-diet control group (NC,n=15),high fat-diet control group (FC,n=15),and high fat-diet with telmisartan group (FT,n =10).NC group was given standard diet and the other two groups were given high-fat diet.At the end of the 12th week,5 rats which were randomly selected from both the NC and FC groups were given euglycermic hyperinsulinemia clamp to see if fat-liver model of rats with insulin resistance was successfully induced,and rat livers were removed for pathological examination to determine the extents of NASH.Afterwards,rats in the FT group was given telmisartan (5 mg/kg·d) while rats in both the NC and FC groups were given the same volume of 0.9% saline solution by intragastric gavage for another 4 weeks.After glucose infusion rates (GIRs) were obtained by the euglycermic hyperinsulinemia clamp technique at the end of the 16th week,all rats were sacrificed and the body weight was recorded,and serum lipids,aminotransferases and fasting blood glucose were measured.The mRNA expressions of peroxisome proliferator activated receptors (PPARs),adiponectin receptor-2 and angiotensin II type-1 receptor in the liver tissue were assessed by semi-quantitative reverse transcriptase polymerase chain reactions.Results The expressions of PPARα,PPARγ and AdipoR2 mRNA in the liver tissue of FC group were decreased significantly compared with the NC group (P<0.01),and the expression of AT1R mRNA of the liver tissue in FC group was increased significantly compared with NC group (P<0.01).Compared with the FC group,the expressions of PPARα,PPARγ and AdipoR2 mRNA in the FT group were increased (P<0.01).Serum aminotransferases,lipids and fasting blood glucose level in the rats of FC group were increased significantly compared with rats of the NC group (P<0.01),and serum aminotransferases,lipids and fasting blood glucose level in the rats of FT group were greatly improved compared with the FC group.Conclusions Telmisartan can improve glucose and lipid metabolism,stop weight gain,decrease liver index,and alleviate steatosis and inflammation of NASH rats by improving insulin resistance.Telmisartan may play an effective role in the protection of rat liver with NASH.

Objective To synthesize a new reagent, 1-(6-bromo-2-benzothiazolyl)-3-(5-bromo-8-quinolyl)-triazene (BBTBQT) and apply to the determination of cobalt. Methods The reagent had been synthesized by diazotization and coupling reaction. After purification and characterization, BBTBQT was tested for its color reaction conditions with cobalt in the presence of cetylpyridinium bromide (CPB). Results In the presence of borax buffer solution at pH value of 9.0, the reagent reacted with cobalt to form a blue stable complex with a molar ratio of 2∶1; the complex had a maximum absorption at 640 nm. The apparent molar absorptivity of the complex is 1.55 ?105 L/(mol?cm). Beer’s law was obeyed in the range of 0-0.28 mg/L for cobalt. The method had been applied to determine cobalt in drainage sediment and vitamin B12 injection solution with a mean relative error of 1.9%-5.8% and a standard relative deviation of 1.7%-3.8%. Conclusion The present method is selective, sensitive, accurate, convenient and suitable for determination of trace cobalt in the samples.

Objective To analyze the differences of time-effect and pathologic feature in the course of development of liver fibrosis between the two kinds of hepatic fibrotic animal models, which were made by CCl 4 and pig serum (PS) methods.Methods Rat models of liver fibrosis were made by using CCl 4 and PS ten week methods.At 6,10,14 and 20 weeks of model making respectively,pathological features of liver fibrosis were observed and analyzed by Masson staining and computerized image analyzing system.Results In CCl 4-induced model,fibrotic pseudolobuli developed at 6 weeks during model making, became typical at 10 weeks, and got stable thereafter.Ballooning degeneration of liver cells was outstanding,and paralleled with model making course.In PS-induced model, fibrosis occurred at 10 weeks during model making, and still developed though the model making was stopped,but ballooning degeneration of liver cells was not presented.Conclusions There was some different in time-effect relation and pathologic feature of liver fibrosis between the two methods of model making. This indicated that different mechanisms were involved in the pathogenesis of liver fibrosis. The two methods of model making should be combined to study of liver fibrosis.The prophylactic and treatment by anti-fibrotic drugs should last no less than 14 weeks.

Objective To observe the changes of SS activity and regulation of GH surrounding cerebral hemorrhage and the hypothalamus,and explore the disorder of SS GH to the affect of local neuronal internal circumstances in stress.Methods With intracerebral hemorrhage model in rats, SS GH content in the hypothalamus and cerebral hemorrhage periphery was determined using the radioimmunoassay.Results The SS content in the hypothalamus far from hematoma and the area surrounding cerebral hematoma elevated obviously, and reached its peak along with the hematoma content,meanwhile the GH content of relevant area trended to upregulate remarkably too.Conclusion While the SS content in the hypothalamus and the area surrounding cerebral hematoma elevated, the GH content of relevant area trended to rise remarkably too, the phenomenon indicated the stress disorder of SS GH axis during the highest peak of hematoma.

Objective To explore the effect of the traumatic brain injury on the fracture healing and the related mechanism. Methods 64 12-week-old SD rats were randomly divided into 2 groups: The femoral fracture with a brain injury group and the femoral fracture group. The bone callus was obtained 1, 2, 3 and 4 week after operation respectively, and observed with the HE staining. The vascular endothelial growth factor (VEGF) and VEGF mRNA in the callus were detected with immunohistochemical staining and hybridization in situ. Results The formation and reforming of the callus in group with brain injury were ahead to only fracture. The percentages of the cells positive for VEGF and VEGF mRNA in the callus were more in group with brain injury than in pure fracture group at the same time point (P<0.05). Conclusion Traumatic brain injury can promote the healing of fracture, which is probably related to an increase in the expression of VEGF.

Objective To evaluate the effects of TIMP-1 and Ang-1 gene-modified BMSCs transplantation on the left ventricular function of rats with myocardial infarction.Methods The rat BMSCs were.transfected with eukaryotic expression plasmid encoding TIMP-1 or/and Ang-1 gene by liposome.Acute myocardial infarction was made in male rats by ligation of the left anterior descending (LAD) coronary artery.BMSCs carrying TIMP-1 or/and Ang-1 gene were injected into the ischemic myocardium after LAD ligatior.Four weeks after the administration,cardiac function was assessed by echocardiography and the hearts were harvested and sectioned for immunohistochemistry to examine the apoptosis,the collagen content and angiogenesis density.Results TIMP-1 and Ang-1 genemodified BMSCs transplantation significantly improved the cardiac function,myocardial apoptosis was alleviated,collagen content decreased and the angiogenesis density in border-zone was increased significantly (P＜0.05).Conclusions The results suggest that the combination of TIMP-1 and Ang-1-gene modified BMSCs transplantation can improve the cardiac function of rats with myocardial infarction.The increase of the blood supply,the alleviation of myocardial apoptosis and ventricle remolding after myocardial infarction possibly play important roles in the mechanism.

Authentications of Chinese herbal medicine have a critical effect in Chinese clinical medicine. DNA molecular marker, as an important component for true or false authentication, is more and more widely used in iden-tification of Chinese medicinal materials. At the same time, many new methods for authentication of Chinese medici-nal materials are continuously emerging. But the systematically comparative analysis of these new methods is lack. The present study taking Lonicera japonica as an example, systematically compared principles, characteristics, ex-periment methods, detection time and the application scope of express sequence tag-simple sequence repeat (EST-SSR), polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), allele-specific PCR (AS-PCR), DNA barcoding and loop-mediated isothermal amplification (LAMP), and put forward corresponding improve-ment opinions. This study can help to screen appropriate approach for rapid authentication of L. japonica and offer demonstrating to other Chinese herbal medicines.

Objective To evaluate the effects of telmisartan by SOCS-3/SREBP-1c pathway and its efficacy of improving insulin resistance (IR) in rats with high-fat diet-induced nonalcoholic steatohepatitis (NASH).Methods A total of 70 SD male rats were assigned randomly into 3 groups: A (normal control,20 rats,basic diet),B (model control,30 rats,high-fat diet) and C (treatment with telmisartan,20 rats,high-fat diet).After the IR-NASH model was made successfully,proved by 10 rats randomly from the group B with euglycemic hyperinsulinemic clamp technique (EHCT) and liver histology,the rats in the group C were intragastrically administrated telmisartan (5 mg/kg/d) for 4 weeks,and then all rats were tested with EHCT and sacrificed to test the blood chemistry,interleukin-6,homeostasis model assessment of insulin resistance,hepatic pathological analysis,and semiquantitative RT-PCR for determining SOCS-3 and SREBP-1c mRNA.Results Rats with high-fat diet developed steatohepatitis and insulin resistance at the 12th week and had more weight gain and higher liver index at the 16th week.IL-6,SOCS-3 and SREBP-1c mRNA expressions in the group B were up-regulated obviously,and each was positively correlated with the velocities of glucose infusion rates at 60~120 min.Blood chemistry and pathological observation in the group C were all improved;both SOCS-3 and SREBP-1c mRNA were down-regulated,and each negatively correlated with VGIR60-120,while serum IL-6 stayed at a high level.Conclusions Telmisartan can remarkably improve hepatic function and insulin resistance in rats with IR-NASH,the mechanisms of which would not be by path of reducing the secretion of IL-6,but by down-regulating the expressions of SOCS-3 and SREBP-1c mRNA.
