江苏省中医院门诊中药饮片处方分析

目的：了解门诊中药饮片处方单剂金额、味数、剂数三个方面的情况,为政府部门及医院制订相关政策提供一些数据支持。方法：调取江苏省中医院（以下简称＂我院＂）2014年6—9月门诊所有中药饮片处方,4个月处方数分别为90 574、103 930、101 435、103 459张,合计399 398张,对其处方单剂金额、味数以及剂数进行统计分析与讨论。结果：我院单剂金额在10~19元区间的处方数最多,为177 945张,占总处方数的44.55%;单剂金额均值为19.48元,味数12~14味区间的处方数最多,为98 365张,占总处方数的24.63%;剂数为14的的处方数最多,为158 267张,占总处方数的39.63%。结论：我院中药饮片处方的单剂金额、味数、剂数相对比较合理,处方饮片味数需从各专科层面进一步分析并加强管理。

中药处方药物剂量的调查与分析

目的对我院中药处方中的药物剂量进行调查与分析,以便监督控制中医临床合理用药,为规定用药范围提供依据。方法采取分层抽样法从内科、外科、儿科等科室中,按每个科室医生总数的比例进行抽样。对处方中出现频率最高的50种药物的常用用药剂量进行统计,再与2005版《中国药典》规定的剂量范围进行比较。结果 2012年我院处方中运用频率最高的50种药物,有64%的药物用量超过药典规定范围。每张处方中药味数以16~20味为主。结论我院处方普遍出现药物剂量超过药典规定用药范围的现象,其原因包含各个方面的因素。

2016-2017年我院中药饮片应用分析

目的 :了解中药饮片处方单剂金额、味数、剂数3个方面的情况,为临床用药和有关职能部门提供参考。方法:收集我院信息系统(HIS)中2016-2017年有关中药饮片的销售信息,对其处方单剂金额、味数及剂数进行统计分析与讨论。结果 :我院单剂金额在20~29元区间的处方数最多,为3 960张,占总处方数的33.00%;单剂金额均值为32.58元;味数在16~20味区间的处方数最多,为5 680张,占47.33%;剂数最多的是5剂,为4 470张,占总处方数的37.25%。结论 :我院中药饮片处方的单剂金额、味数、剂数相对比较合理,中药饮片的使用是规范合理的。

Modified DIX model for ion-exchange equilibrium of L-phenylalanine on a strong cation-exchange resin

L-phenylalanine, one of the nine essential amino acids for the human body, is extensively used as an ingredient in food, pharmaceutical and nutrition industries. A suitable equilibrium model is required for purification of L-phenylalanine based on ion-exchange chromatography. In this work, the equilibrium uptake of L-phenylalanine on a strong acid-cation exchanger SH11 was investigated experimentally and theoretically. A modified Donnan ion-exchange （DIX） model, which takes the activiW into account, was established to predict the uptake of L-phenylalanine at various solution pH values. The model parameters including selectivity and mean activity coefficient in the resin phase are presented. The modified DIX model is in good agreement with the experimental data. The optimum operating pH value of 2.0, with the highest t-phenylalanine uptake on the resin, is predicted by the model. This basic information combined with the general mass transfer model will lay the foundation for the prediction of dynamic behavior of fixed bed separation process.

Gaining Satisfaction and Trust in a Brand Website

This study attempts to examine whether ＂trust＂ and ＂satisfaction＂ in a brand website are affected by the level of website interactivity as well as the four facets （aesthetics, playfulness, service excellence, and customer return on investment） of the Experiential Value. Three interactive versions （low, medium, and high） of a website for a fictitious laptop brand were designed. An online experiment was conducted 180 students participated in the study. Data analysis indicated that higher levels of trust and satisfaction were generated when participants were exposed to the low interactive version of the website. Regarding the four facets of Experiential Value, aesthetics and customer return on investment （croi） have positive relationship with both trust and satisfaction in the brand website. Playfulness appears to have negative whereas excellence does not have significant relationship with trust and satisfaction. Limitations and guidelines for future research are provided.
