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 changes of choroidal thickness after ranibizumab treatment for non-proliferative diabetic retinopathy (NPDR) with macular edema,and determine the association between choroidal thickness and visual acuity.Methods Twenty-three eyes from 23 patients diagnosed with NPDR and diabetic macuiar edema were treated with 3 monthly intravitreal injections of ranibizumab.The subfoveal choroidal thickness and central macular thickness were measured,and the best corrected visual acuity was recorded.Changes of subfoveal choroidal thickness,correlation between subfoveal choroidal thickness and best corrected visual acuity were assessed at 3 months follow-up.Results After 3 monthly anti-VEGF treatments,subfoveal choroidal thickness and central macular thickness decreased significantly,there was no statistical difference at 1 month and 2 months compared with pre-treatment (all P ＞ 0.05),but there was statistical differences at 3 months compared with pre-treatment (P =0.04,0.01).In the treatment,the best corrected visual acuity increased gradually,there was no statistical difference at 1 month and 2 months compared with pre-treatment (all P ＞ 0.05),but there was statistical differences at 3 months compared with pre-treatment (P =0.04).Before the treatment,the subfoveal choroidal thickness was positive correlated with macuiar retinal thickness (R2 =0.94,P =0.00);And the best corrected visual acuity before treatment and 3 months after treatment had a positive correlation (R2 =0.93,P =0.00;R2 =0.82,P =0.00).There was a positive correlation between central macular thickness and best corrected visual acuity at 3 months after treatment (R2 =0.83,P =0.00).There was a positive correlation in the best corrected visual acuity between before treatment and 3 months after treatment (R2 =0.84,P =0.00).Conclusion The subfoveal choroidal thickness is a clinical index to evaluate the efficacy of anti-VEGF in the treatment of diabetic macuiar edema.Baseline subfoveal choroidal thickness can be considered as one of the indicators of clinical efficacy in the short term.
