Objective To study the effect of anti-hepatitis B virus of Lamivudine combined with Saikosaponins in vivo. Methods Chongqing duck hepatitis B model was selected and given to Lamivudine combined with Saikosaponins(combined group) oral treatment 28d, then the ducks were observed 7d after drug withdrawal. The levels of serum HBV DNA, HBsAg and transaminase(ALT, AST) were detected before and after treatment, and compared with that in Lamivudine group and Saikosaponins group as control. Results In combined group,the levels of serum HBV DNA and HbsAg were significantly decreased(P ＜ 0.05), and 7d after drug withdrawal the levels of serum HBV DNA and HBsAg showed no" anti-jump" compared with that at drug treatment 28d(P ＞ 0.05). In Lamivudine group and Saikosaponins group the levels of those increased again 7d after drug withdrawal (P ＜ 0. 05). In each group the levels of serum ALT and AST did not change within the same phase during drug treatment 28d and 7d after drug withdrawal(P ＞ 0. 05). Conclusion Lamivudine combined with Saikosaponins in vivo had the effect of anti-hepatitis Bvirus, and the effect was stable and lasting.

Objective To investigate the curative effect of Candesartan on chronic systolic heart failure in Tibetan pla?teau. Methods A total of 526 patients with chronic systolic heart failure were divided into two groups randomly (Treatment group N=252;Control group N=274). Regular medicines, such as cardiac, diuretic and vasodilator drugs , are given to pa?tients in both groups according to their primary underlined diseases. Additionally, enalapril is added in control group, while candesartan is added in treatment group. Improvement of cardiac function, LVEF, LVEDD and blood pressure were compared between these two groups after 8 weeks. Results There was no significant difference in effective rate (i.e., 45.2%in treat?ment group and 44.9% in control group, respectively), efficiency rate (i.e. 54.8% in treatment group and 55.1% in control group, respectively) and inefficiency rate (i.e. 2.0%in treatment group and 2.2%in control group, respectively) between treat?ment and control groups . After treatment, LVEF in the two groups are all improved, while LVEDD and blood pressure both de?creased with statistical significance. However, the difference between the two groups is not significant. Conclusion No sta?tistical difference was found in curative effect on chronic systolic heart failure in Tibetan Plateau between two groups.

Transient receptor potential A1 (TRPAl) is a cold sensitive cation channel, which could also be activated by various pungent compounds. As a transduction channel in a number of sensory modalities, TRPAl expressing in heterogonous systems serves to provide great convenience in pharmacological analysis and functional investigation. Due to cellular toxicity, establishment of stable TRPAl cell line has always been challenging. Nevertheless, the first stable human embryonic kidney (HEK-293) cell line with un-controlled expression of TRPAl was successfully established. It was also confirmed that this stable cell line retained TRPAl expression for more than 25 passages in culture. The functional analysis of the cell response verified the stability and specificity of this novel recombinant TRPAl cell line. Altogether, the data indicated this TRPAl-HEK cell line would be a useful tool for functional analysis of TRPAl and for the development of high throughput screening (HTS) compatible assay in the effort to identify TRPAl modulators.

Primary liver cancer (PLC) includes hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (CC).In recent years, the incidence of PLC has increased significantly in the world.At present, the therapy for liver cancer tends to diversify, but surgical resection is still the first choice and the most effective treatment for HCC in general.As the biomedical, evidence-based medicine, and medical humanities are proposed, to achieve the best therapeutic effect and minimize the trauma has become the goal of modem surgery.Moreover, this could promote the transformation of surgical model from traditional experiential surgery to precision surgery.Besides, as the critical techniques of treating HCC in preoperative evaluation,operative procedures, perioperative management and the innovation of surgical instruments develop fast, precise liver resection has come into being.And now this concept is getting more and more attention from hepatobiliary surgeons.In this paper, the progress on the application of precise liver resection in the treatment of PLC is reviewed based on the preoperative evaluation and intraoperative procedures.

Objective To investigate the statistical.method for analyzing nurse job burnout Data. Methods Hotelling T2 test and multivariate analysis of variance(MANOVA)were used to analyze nurse job burnout datum. Results There was statistical significance between different cities,different ethnieities in the personal achievements,hut from three dimensions of the whole job burnout,there are no statistical sig-nificant differences among different cities, different ethnicities and different ages. Conclusions The use of Hotelling T2 test and multivariate analysis of variance to analyzing nurse job burnout data, not only ob-tain overall conclusion, and further use of single-variable analysis may also gain comparative results of each dimensions.

Objective:Investigate whether adenosine disodium triphosphate for injection can reduce the systemic inflammatory response which induced by cardiopulmonary bypass.Methods:Forty-seven patients scheduled for cardiac surgery over 30 min following CPB were randomly divided into two groups. In treated group(n=23),adenosine disodium triphosphate for injection(2 mmol/L) was added into the prime during CPB, but in control group(n=24), no adenosine disodium triphosphate for injection was added. Blood samples were drawn from the radial artery at the following time points:(1)before CPB;(2)30 min after aortic clamping;(3)30 min after aortic declamping;(4) 12 h after aortic declamping;(5)24 h after aortic declamping.Enzyme-linked immunosorbent assays(ELISA) were used to measure the concentration of tumor necrosis factor-?(TNF-?), interleukin-6(IL-6), in plasma,CK-MB in plasma level were measured too.Results:The concentration of TNF-??IL-6?CK-MB levels in plasma level of two groups showed no difference before CPB. They all had increased by 30 min after aortic clamping(P

Objective This study evaluates the Anti- hypoxic effect of Fo li um Bambusae extract (FBE). Methods The survival time of mice under the conditi on of closed normobaric hypoxia, and those subjected to KCN, NaNO2 and lidoc aine poisoning, and the time of electrocardiograph disappearance after occlusio n of trachea and the duration of continuous gasping in mice after decapitation were used to evaluate the Anti- hypoxic effect of FBE. Results FBE ( 22.5 m g/kg, 45.0 mg/kg, 90.0 mg/kg) prolonged the survival time of mice under the c ondition of closed normobaric hypoxia, prolonged the survival time in mice subj ected to KCN, NaNO2 and lidocaine poisoning and prolonged the time of electro cardiograph disappearance and the duration of gasping in decapitated mice. Conc lusion FBE can increase the anti- hypoxic effect of animals.

Aim The aim is to purify fibrinolytic enzyme from Scolopendra subspinipes mutilans L.Koch and to study the thrombolytic and anticoagulant effect.Methods Scolopendra subspinipes mutilans L.Koch fibrinolytic enzyme(SSFE) was purified by ammonium sulphate precipitation,DEAE-cellulose and SephadexG-75 column chromatography from Scolopendra subspinipes mutilans L.Kochby.And fibrinolytic activity was determined by fibrin plate.The anticoagulant effect was measured on mice with haemolytic test and hemorrhagic test.The thrombolytic effect was measured with rats In vitro and in vivo,and the activated partial thromboplastin time(APTT),plasma prothrombin time(PT),thrombin time(TT) were measured.Results SSFE was single component with fibrinolytic activity and without any hemolyzation and hemorrhagic activity.All doses of SSFE(2,5,10 mg?kg-1) could obviously prolong activated partial thromboplastin time(APTT) and thrombin time(TT) ;Middle dose of SSFE(5 mg?kg-1) could prolong plasma prothrombin time(PT) while high dose of SSFE(10 mg?kg-1) didn't prolong obviously.Conclusion SSFE has obvious thrombolytic effect and anticoagulant effect.
