基于证候要素的中风辨证论治

中风病是临床的常见病、多发病。本病病因较多,病情变化迅速,证型繁杂,不同的文献中证候分类差异较大。证候分类的繁杂给临床工作者治疗中风病带来极大不便。本文对以证候要素(内风、内火、痰湿、瘀血、气虚、阴虚)为切入点论治中风病的理论进行探讨,并举例论证其临床疗效。     

Vaccination inhibits the human adenoviral transduction in a mouse keratoconjunctivitis model

Adenovirus infections are a major cause of epidemic keratoconjunctivitis (EKC), which can lead to corneal subepithelial infiltrates and multifocal corneal opacity. In the current study, we investigated the use of an E1/E3-deleted adenovirus serotype 5 (Ad5) vector as a vaccine administered intramuscularly (IM) or intranasally (IN) against subsequent challenges with a luciferase-expressing Ad5 (Ad5-Luci) vector via eyedrop. We evaluated the adaptive immune response to Ad5 vector vaccination and confirmed a robust polyfunctional CD8 T cell response in splenic cells. Neutralizing Ad5 antibodies were also measured in the sera of vaccinated mice as well as Ad5 antibody in the eye wash solutions. Upon challenge with Ad5-Luci vector 8 weeks post the primary immunization, transduction was significantly reduced by > 70% in the vaccinated mice, which was slightly better in IM- vs. that in IN-vaccinated animals. Resistance to subsequent challenge was observed 10 months post primary IM vaccination, with sustained reduction up to 60% in the Ad5-Luci vector transduction. Passive immunization of naive mice with antisera from IM to vaccinated mice subsequently challenged with the Ad5-Luci vector resulted in approximately 40% loss in transduction efficiency. Furthermore, the mice that received IM immunization with or without CD8 T cell depletion showed > 40% and 70% reductions, respectively, in Ad8 genomic copies after Ad8 topical challenge. We conclude that Ad-vector vaccination successfully induced an adaptive immune response that prevented subsequent Ad transduction in the cornea and conjunctiva-associated tissues in a mouse model of adenovirus keratoconjunctivitis, and that both cellular and humoral immunity play an important role in preventing Ad transduction.     

脉络学说营卫理论指导心律失常辨证论治

经脉包括经(气)络和血(脉)络,清代周学海《读医随笔》将气络末端称为"气之细络",脉络末端称为"血之细络"。心之气络涵盖心脏起搏与传导系统等广泛调控机制,心之脉络涵盖冠状动脉循环系统,心之气络与脉络相互协调,营卫相偕而行,共同维持心脏正常功能。各种致病因素导致营卫异常而发为心律失常,基于脉络学说营卫理论"损其心者,调其营卫"(《难经·十四难》)治疗原则指导心律失常辨证论治,同时充分结合现代致病因素和致病特点,分别选用调节卫气营血之方药,标本兼治,以期为临床诊疗提供有益借鉴。     

Neighborhood: A Conceptual Analysis

Researchers interested in measuring neighborhood‐level effects should understand how “neighborhood” is defined within nursing sciences and other sciences, and the inherent strengths and weaknesses of current research methodologies. This concept analysis provides clarity around the concept of neighborhood within the context of health, analyzes the current state of development of the neighborhood concept, and proposes areas for future nursing research. Using the Rodger's Method of analysis, the concept of neighborhood within nursing and public health research is described based on existing literature. The concept's attributes, related concepts, antecedents, and consequences are given from the literature. Comparisons of the use of neighborhood are made between nursing, public health, sociology, and other sciences. The evolution of the concept of neighborhood throughout history is described, and important implications for future research are discussed.     

长春西部地区1258例过敏原特异性IgE检测结果分析

目的了解长春西部地区过敏原特异性IgE分布情况。方法应用免疫印迹法检测1 258例患者的19种吸入性及食物性过敏原特异性IgE抗体,统计过敏原结果及种类。结果 1 258例患者,检出至少一种特异性IgE阳性率为34.0%。男性阳性率为33.5%;女性阳性率为34.5%。男女间阳性率差异无统计学意义(P> 0.05)。吸入性过敏原阳性率由高到低依次为:普通豚草14.2%、艾蒿11.4%、屋尘螨/粉尘螨8.1%、猫毛3.8%、狗上皮2.4%、柳树/杨树/榆树2.1%,屋尘1.6%、蟑螂1.6%、点青霉/分枝孢霉/烟曲霉/交链孢霉1.2%、葎草1.1%。食物性过敏原阳性率由高到低依次为:鸡蛋白2.9%、鳕鱼/龙虾/扇贝2.7%、牛奶2.3%、黄豆1.9%、蟹1.5%、虾1.3%、牛肉1.2%、花生1.0%、羊肉0.8%。混合过敏达到了相当高的比例。结论长春西部地区吸入性过敏原以普通豚草、艾蒿和屋尘螨/粉尘螨为主;食物性过敏原以鸡蛋白、鳕鱼/龙虾/扇贝、牛奶为主,明确过敏原,对过敏性患者的预防和治疗有重大意义。
