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.

BACKGROUND:Currently, the treatment of proximal humeral fractures mainly contains joint preservation (conservative treatment, open reduction and internal fixation) and arthroplasty, but how to choose the treatment is stil controversial. OBJECTIVE:To evaluate and compare the clinical outcomes of joint preservation versus arthroplasty in the treatment of displaced 3-or 4-part humeral fractures in randomized control ed trials using meta-analysis. METHODS:Medline (January 1966 to December 2013), PubMed (January 1980 to December 2013), Embase (January 1990 to December 2013), Science (January 1990 to December 2013), Springer (January 1990 to December 2013), China National Knowledge Infrastructure (1994 to 2013), and Wanfang database (1982 to 2013) were searched for randomized control ed trials addressing joint preservation and arthroplasty for 3-or 4-part proximal humeral fractures. Articles meeting the inclusion criteria were included. The related data were extracted and loaded onto Comprehensive Meta-Analysis Software for meta-analysis. RESULTS AND CONCLUSION:Seven articles with 320 patients (165 patients undergoing joint preservation and 155 patients receiving arthroplasty) were accepted in this mete-analysis and al of them were high-quality English researches by modified Jadad Scale. Meta-analysis results displayed that the random-effects mean Constant score across al types was 55.9 (95%CI:50.7-61.1;P<0.001). Constant score was higher in the joint preservation group than in the arthroplasty group (P<0.01). The study displayed significant heterogeneity (I2 0.001). In the meta-analysis, Constant scores were decreased with increasing rate of male to female and rate of tuberosity resorption. These results suggested that 3-or 4-part proximal humeral fractures demonstrate improved Constant scores when treated with joint-preserving options compared with arthroplasty. Moreover, age, fracture pattern, gender ratio and complication rate are significant predictors of the Constant score. Given the observed heterogeneity and variance in treatment techniques in the included studies, more randomized control ed trial studies are needed to definitively recommend joint-preserving techniques versus arthroplasty for treatment of 3-or 4-part proximal humeral fractures.=88%, Q statistic=107.6, Q=13;P<0.001).
