Objective To evaluate the operation efficiency of clinical departments in hospitals and study its influencing factors.It provides reference for hospital decision makers to optimize the allocation of health resources.Methods DEA combi-ning with DRG indicator was used to comprehensively evaluate the input-output efficiency of study sample.Slacks Variable of DEA and Tobit regression were performed to identify improvement goals and influencing factors.Results 35％of clinical depart-ments health resource allocation were effective,and the pure technical efficiency and scale efficiency of 35％of clinical depart-ments were less than 1.The number of bed turnover had a positive effect on the operation efficiency of clinical departments and had statistical significance.Conclusion The clinical departments in the sample hospitals had a low level operating efficiency.DEA method combined with DRG index can better evaluate the operational efficiency of clinical departments.and assist hospital decision makers to adjust the allocation of health resources.According to the results of DEA,the hospital decision makers could adjusted the allocation of health resources,and combined with the influencing factors and actual needs to reinforce delicacy man-agement of clinical departments.

Objective:To investigate the influence of HBV infection on the prevalence of fatty liver disease in Jinchang cohort and provide theoretical evidence for the prevention and treatment of fatty liver disease.Methods:Epidemiological investigation, laboratory examination and abdominal ultrasound were conducted in the baseline population of Jinchang cohort to collect the basic data, the differences in the prevalence of fatty liver disease under different HBV infection patterns were described and compared and the influence of different HBV infection patterns on the prevalence of fatty liver disease were evaluated by using logistic regression analysis.Results:The baseline Jinchang cohort population totaled 45 605, including 27 917 males and 17 688 females. The male to female ratio was 1.6∶1. The mean age of the overall population was 46.49 years. Among the 8 common HBV infection modes in the Jinchang cohort, the prevalence of fatty liver was low in HBsAg, HBeAg and HBcAb positive, HBsAg and HBcAb positive, and HBsAg, HBeAb and HBcAb positive groups. For 4 serum markers of HBV infection, the prevalence of fatty liver disease in HBsAg and HBeAg positive groups was lower than that in HBsAg and HBeAg negative groups. Logistic regression analysis showed that being HBsAg and HBcAb positive ( OR=0.61, 95% CI: 0.39-0.98) and HBsAg, HBeAg and HBcAb positive ( OR=0.52, 95% CI: 0.30-0.89) could reduce the risk for fatty liver disease. Conclusion:Acute HBV infection reduces the prevalence of fatty liver disease, and the reason may be related to the disturbance of the body's fat metabolism by active HBV replication.

Objective To test the influence of peripherally inserted central catheter ( PICC) phlebotomizing and venipuncture ( VP) phlebotomizing on detection of coagulation function, so as to comfirm the feasibility of PICC. Methods Took 2 blood samples from the same patient, and divided the blood samples in to the PICC group and the VP group according to the methods of phlebotomizing to adopt a parallel controlled trial. Pearson correlation analysis and Bland-Altman analysis were taken during the following research. Results The 5 items of blood coagulation indexes testing showed that the results of PICC group and VP group were highly correlated, and the correlation coefficient was 0. 990 to 0. 997. The mean biases obtained by Bland-Altman analysis were closer to 0. Conclusion PICC and traditional method of VP showed obvious correlation and accordance in terms of the 5 indexes of coagulation function detection, which indicated that PICC is feasible for coagulation function detection.

Objective To compare the Barcelona clinic liver cancer staging classification (BCLC), the Japan integrated staging score (JIS), the cancer of the liver Italian program score (CLIP) and Chinese staging system in terms of their ability to predict outcomes and to guide option of therapy in patients with hepatocellular carcinoma (HCC) in China.Methods Clinical data of 861 HCC patients from Zhongshan Hospital between 2001 and 2002 were retrospectively analyzed. Patients were classified acccording to different staging systems. Survival for patients in different stages and the effects of therapeutic methods on survival time were compared. Results BCLC, JIS and Chinese staging system showed the ability in predicting survival for patients in different staging. CLIP failed to show significant difference in survival rates for each subgroup. There was no significant difference in survival rate between surgery and transarterial chemoembolization (TACE)/transarterial embolization (TAE) for patients classified as BCLC stage C, CLIP scores more than 3 or Chinese stage Ⅲ a.The survival rate, however, was higher in patients received operation than those received TACE/TAE if they were classified as earlier stages. Conclusions The BCLC, JIS and Chinese staging systems show prospective ability for Chinese HCC patients in prediction outcomes, whereas the BCLC and the Chinese staging systems are better at both predicting outcomes and guiding the option of treatment.

Objective To study the adrenal function in rats with pulmonary acute lung injury (ALI) induced by Escherichia coli (0111B4) . Methods ALI rat model was induced by intratracheal injection of E.coli (3 ml/kg,0111B4,(4.4-5.6) x 10~(12) CFU/L).ALI rats were then randomly divided into three groups,and each group had 10 rats.Mechanical ventilation was applied at three time points,6 hours,24 hours,and 36 hours after injection At each time point 8 rats were used as control with saline administered intratracheally.The plasma ACTH and corticosterone levels were measured after stimulated by 100 μg porcine ACTH.Results Compared with control group,the model group had a higher level of plasma ACTH at each time point (P < 0.01).The plasma ACTH level reached the peak at 24 hours.The model group had a higher level of plasma corticosterone at 6 hours (P < 0.01) and 24 hours (P <0.05),but had a lower level of plasma corticosterone at 36 hours (P < 0.05).The plasma corticosterone level reached the peak at 6 hours in model group,which was higher than 24 hours (P < 0.05).After stimulated by ACTH,the increased levels of corticosterone were lower in model group than those in control group (6 hours,P < 0.05; 24 hours and 36 hours,P < 0.01).Conclusions Adrenal dysfunction may occur at early stage of ALI in rats.With the disease developed,adrenal response to ACTH decreased.Low dose corticotrophin-stimulated test could evaluate adrenal function in rats with pulmonary ALI induced by Escherichia coli (O111B4).
