The self-book renewing information in medical library was classified, which showed that the 3 months in a year and the period in a day with the largest number of readers who visited the medical library Website were characterized by their rigid need. In addition, the evidence was provided for the issuing time of information on li-brary information issuing platform in order to optimize the popularizing effect of library.

According to the actuality of domestic medical equipment management and its main problems, development tendency of current equipment management are analyzed in four aspects of the norms of medical equipment management standards and details, the expansion of medical equipment information management in whole course, attention to medical engineering disciplines, and strengthening the quality control of medical equipment and application of security technology.

Objective To investigate the value of modified NIHSS and MRI-PC-ASPECTS for the long-term prognosis in posterior circulation ischemic stroke. Methods Seventy eight patients with posterior circulation ischemic stroke were divided into two groups depended on MRS: good outcome group and bad outcome group. General information of patients was collected and vascular risk factors, NIHSS, MRI-PC-ASPECTS of the two groups were compared. Results The scores of admission NIHSS and highest NIHSS of bad outcome group were higher than that of good outcome group. The scores of MRI-PC-ASPECTS, T admission NIHSS (42-admission NIHSS) and T highest NIHSS of bad outcome group were lower than that of good outcome group (P<0.05). The areas under the ROC curves of MRI-PC-ASPECTS+T highest NIHSS, MRI-PC-ASPECTS, T highest NIHSS and T admission NIHSS were 0.907, 0.821, 0.870, 0.744, respectively (P<0.05). Conclusion NIHSS and MRI-PC-ASPECTS can predict the functional prognosis in patients with posterior circulation ischemic stroke.

Objective To screen the best processing technology of prepared Rhubarb by multi- component composite score combined with response surface.Methods The composite score of seven components, i.e., gallicacid, chrysophanol-8-O-β-D-glucopyranoside, aloeemodin, rhein, emodin, chrysophanol, physcion, was taken as indicators. Three factors and three levels of response surface Box-Behnken were used in experimental design. The effects of factors including rice wine volume, moistening time, and steaming time on processing technology of stewed Rhubarb were studied, and the optimized processing parameters were chosen.Results Design Expert 8.05 software was used for data analysis. Multivariate quadratic mathematical model of the sample and examine factors composite score regression equation of seven ingredients content were set up. The best processing conditions of prepared Rhubarb were as following:adding 36.6 mL rice wine into per 100 g raw material;moistening time continued for 2.16 hours;steaming time continued for 10.96 h. According to actual production, the optimized processing conditions of prepared Rhubarb are as following:adding 35 mL rice wine per into 100 g raw material;moistening time continued for 2 h;steaming time continued for 11 h.Conclusion The optimized processing technology can reasonably control the quality of prepared Rhubarb, and provide the basis for the quality standards of its decoction pieces and clinical application.

Objective　To observe the change of lipidemia and lipoprotein in wistar rats with fluorosis.Methods　14 wistar rats were fed normal food with hyper concentration of NaF water (100 mg/L) for six months,the TC,TG,HDL-c,LDL-c,APO AI APO B and AI,R-CHE were measured in serum.Results　The result show that there are an increace of T C,TG,HDL-c,LDL-c,APO AI，APO B and AI,R-CHD compared with normal rats (P <0.05).Conclusions　The result indicate that the fluorosis can increase the lipidemia and lipoprotein in rats with fluorosis and lead to athero selerosis.

Objective To investigate the relationship between tumor necrosis factor-alpha (TNF-α) and development of chronic obstructive pulmonary disease (COPD).Methods COPD patients and controls were divided into three groups: COPD group (n=66), smoker control group (n=42) and health control group (n=23). COPD group was further divided into the serious group (n=23) and non-serious group (n=43). The concentration of TNF-α of all cases was detected by human Th1/Th2 cytokine kit.Results The concentration of TNF-α in the COPD group was significantly higher than that of the smoker and healthy groups ( P<0.01). Furthermore, compared to non-serious COPD group, the concentration of TNF-α was higher in the serious COPD group ( P<0.05).Conclusion The concentration of TNF-α might be related with the pathogenesis and development of COPD.
