浅析医疗机构中志愿者体系的管理和发展

医疗志愿者体系发展至今，在国外已有相当的规模和管理机制，但是对于国内的医疗机构来说，仍在不断的探索中。本文将结合复旦大学附属儿科医院于2002年6月1日成立的首批“阳光爱心”志愿者队伍的情况，探究志愿者体系在医疗机构中的管理和发展。     

Sedation with sufentanil and midazolam decreases pain in patients undergoing upper limb surgery under multiple nerve block

Multiple nerve blocks may be painful and a source of discomfort. We assessed the efficacy of sufentanil 5 microg combined with midazolam 1 mg in decreasing pain in outpatients after a midhumeral multiple nerve stimulation technique. Visual analog scores for pain were significantly lower in those patients who received sedation before the block, both at the time of block performance (14 +/- 1 vs 27 +/- 2 mm, P < 0.0001) and at discharge (11 +/- 1 vs 24 +/- 2 mm, P < 0. 0001). We conclude that the association of sufentanil and midazolam produced minimal sedation while significantly reducing pain experienced by patients undergoing multiple nerve stimulation.     

中医疾病证候学研究方法初探

此次调查在西医辨病的基础上,以中医辨证理论方法为核心,按照事先设计的方案,收集特定时间内膝关节骨关节炎患者的病状,先进行计量诊断确立辨证要素,再进行聚类分析及logistic回归分析等筛选出特异性较高的症状,为疾病辨证分型、辨证标准的阐明提供依据.是一种值得介绍的中医证候研究方法.     

弦滑脉辨析--与傅文胜、薄震东、孙建中商榷

《中医杂志》1991年第2期薄震东、孙建中的《“弦滑”脉之管见》(以下简称《管见》)，与2000年第9期傅文胜的《脉弦滑质疑》(以下简称《质疑》)，从不同角度论述了相同的观点：弦、滑脉不能相兼。细阅两文，笔者发现两文中颇多错讹之处。两文作者对弦、滑两种脉象都尚未了解清楚。王叔和说脉诊是“在心易了，指下难明。”倘若在心还尚未“了”，指下又岂能“明”?为免贻误后学，不能不就弦、滑脉象作进一步辨析。     

小脑参与认知功能机制的研究进展

认知是指人脑为获取和应用知识,将外界信息转化成内在心理活动的复杂过程。自 1998年Schmahmann和Sherman提出“小脑认知-情感综合征”起,小脑认知功能的研究越来越受到关注。 本文通过回顾国内外相关研究,从小脑的解剖与认知功能、小脑的神经网络机制以及交叉性小脑神经 机能联系不能 3 个角度探讨了小脑在认知神经网络中的作用及机制,旨在提高对小脑参与认知功能的 认识。

Identification of Inhibitors and Drug Targets for Human Adenovirus Infections

Adenoviruses can cause infections in people of all ages at all seasons of the year. Adenovirus infections cause mild to severe illnesses. Children, immunocompromised patients, or those with existing respiratory or cardiac disease are at higher risk. Unfortunately, there are no commercial drugs or vaccines available on the market for adenovirus infections. Therefore, there is an urgent need to discover new antiviral drugs or drug targets for adenovirus infections. To identify potential antiviral agents for adenovirus infections, we screened a drug library containing 2138 compounds, most of which are drugs with known targets and past phase I clinical trials. On a cell-based assay, we identified 131 hits that inhibit adenoviruses type 3 and 5. A secondary screen confirmed the antiviral effects of 59 inhibitors that inhibit the replication of adenoviruses type 3 or 5. Most of the inhibitors target heat shock protein, protein tyrosine kinase, the mTOR signaling pathway, and other host factors, suggesting that these host factors may be essential for replicating adenoviruses. Through this study, the newly identified adenovirus inhibitors may provide a start point for developing new antiviral drugs to treat adenovirus infections. Further validation of the identified drug targets can help the development of new therapeutics against adenovirus infections.     

Early Age Shrinkage and Mechanical Effect of Ultra-High-Performance Concrete Composite Deck: A Case Study with In Situ Test and Numerical Simulation

For the Honghe Bridge project located in Yunnan Province, Southwest China, a steel/ultrahigh-performance concrete (UHPC) composite deck is used in the suspension bridge with a 700 m main span, and the steel stud connectors are used in the 50 mm–thick UHPC layer. To investigate the shrinkage behavior of UHPC and the relevant influence, the in situ time-dependent strain is measured continuously, and within the 20-day curing time, the material behavior is summarized based on test results. This paper proposes a prediction model for UHPC shrinkage which is refined from the widely used B3 model for normal concrete material, and the parameter values are modified and optimized by experimental comparison. Combining the numerical model and the finite element analysis model of the composite deck, the detailed mechanical state in structural parts is studied. For the practical construction, the simulation results indicate that the small thickness of UHPC above the stud and weak bond strength can influence the eventual structural performance greatly. In the discussion of stress distribution at different locations of the deck, the potential crack on the edge and the corner of the UHPC–steel interface and the mechanical damage on the stud connector around are also indicated.
