从湿热体质论治脂溢性脱发

中医对于脂溢性脱发，传统多按"血热风燥""血虚风燥""湿热""肝肾不足"等分型论治，虽能取得一定的临床疗效，暂时缓解病情，但难以根治，给患者带来困扰。倪诚教授根据国医大师王琦教授所提出的"肤-体相关论""体质可调论"，认为湿热体质是脂溢性脱发发病的主要土壤，指出瘀浊蛀发是脂溢性脱发的病机要点，治疗上以清利湿热调体治本、凉血活血为主、佐以滋养肝肾，方用茵陈蒿汤合升降散加减配合外洗经验方，从标本兼顾、分期论治、内服外洗等方面治疗脂溢性脱发，在临床上取得良好的疗效。     

基于中医古籍文献的升降散应用溯源及探析

通过对中医古籍中有关升降散论述的文献梳理,全面探讨其内涵。本方是在大黄、僵蚕为雏形的基础上增加蝉蜕、姜黄而成方,几经易名,终在杨璿《伤寒瘟疫条辨》中为后人所熟知。本方广泛用于治疗瘟疫,以丸剂、散剂为主,方便携带,便于服用;重用大黄旨在祛邪、逐秽;应用时视人之体质强弱和量其毒之轻重而判断用药多寡,并辅以米酒、生蜜等以顾护正气。杨璿将其由治疗“热疫”的专方扩展为治疗“表里三焦大热”的通用方剂,扩大了本方治疗疾病范围。     

柴胡疏肝散、四君子汤对肝郁、脾虚大鼠Th细胞蛋白激酶C表达的影响

目的研究柴胡疏肝散、四君子汤对肝郁、脾虚大鼠Th细胞蛋白激酶C(PKC)表达的影响及其意义。方法应用RT—PCR法研究柴胡疏肝散、四君子汤对Th细胞PKCmRNA表达的影响。结果脾虚时PKCmRNA表达水平明显低于正常对照组 (P <0 .0 5 ) ,四君子汤治疗后恢复正常 (P <0 .0 5 ) ,柴胡疏肝散治疗后仍明显低于正常对照组 ;肝郁时PKCmRNA表达水平明显高于正常对照组 (P <0 .0 5 ) ,柴胡疏肝散治疗后恢复正常 (P <0 .0 5 ) ,但四君子汤治疗效应不明显。结论肝脾两脏在T细胞尤其是Th0的活化中具有相关性 ;PKC参与了肝脾这种相关的发生。

Nitric oxide administration after the ventilator: evaluation of mixing conditions

Background: Because of the potential toxicity of nitric oxide (NO) and its oxidising product nitrogen dioxide (NO₂), any system for the delivery of inhaled NO must aim at stable and predictable levels of NO and as low concentrations as possible of NO₂.
Methods: In a laboratory set-up, we have evaluated mixing conditions in a system where NO is added after the ventilator with continuous flow. Mixing was studied by using carbon dioxide (CO₂) as a tracer gas since capnography has a short response time (360 ms) in comparison with measurements of NO with electrochemical fuel cells (response time of 18s). CO₂ (in volumes corresponding to an ideal mixture of 1,3 and 6%) was fed, after the ventilator, either into plain breathing tubing, into one or two soda lime absorbers, or into an empty and a soda lime-filled canister, at different ventilatory rates and different I: E ratios. Samples were drawn from the inspiratory limb close to the Y-piece. NO was added in the same way and in the same volume as the highest concentration of CO₂.
Results: CO₂ added to plain tubing resulted in peak levels up to five times the set levels, while addition to a mixing box with an empty and a soda lime-filled canister resulted in even mixing with gas concentrations close to the ideal. When NO was fed into plain tubing, low levels were measured at the Y-piece, indicating poor mixing. Gas supply to a mixing chamber resulted in even concentrations.
Conclusions: Even and predictable levels of NO can be obtained with continuous flow of NO to the inspiratory limb, after the ventilator, if a mixing chamber is used. To obtain adequate mixing, the volume of the mixing box should be greater than the tidal volume.     

腹泻灵外敷治疗急性肠炎的临床观察和实验研究

以丁香、肉桂、细辛等组成的腹泻灵外敷脐部(神阙穴)治疗急性肠炎106例,痊愈率为91.5%。并随机设立痢特灵、庆大霉素、山莨菪碱西药对照组100例,痊愈率为88%。两组相比,腹泻灵组对各项观察指标的改善情况均明显优于西药组(p<0.01)。动物实验证明,腹泻灵内用无急性毒性反应及过敏反应,长期外用无蓄积性毒性作用,对球结膜与完好皮肤及破损皮肤均无刺激作用。
