针刺不同经穴对正常人事件相关电位P3a和P3b的影响

目的：探讨针刺不同经脉穴位对大脑注意功能的影响,为进一步揭示针刺心经经穴神门效应的脑功能与脑整合机制奠定基础。方法：选择10名健康青年大学生作为试验对象,采用视觉新奇刺激和靶刺激诱导P3a和P3b电位,采用Neuroscan事件相关电位系统,选择测量时间窗口为330～430ms和400～600ms,观察手针心经神门穴与肺经太渊穴前后P300强度分布的变化。结果：针刺神门或太渊后P3a、P3b的波幅均显著降低,但降低的程度受针刺穴位的调控和影响;在电极FCz记录位置,针刺神门引起更大程度的P3a波幅的降低（P〈0.05）。结论：手针神门或太渊穴均能影响大脑的注意功能,针刺神门对人体大脑注意功能的影响更大。     

艾灸对类风湿关节炎大鼠的治疗作用及其机制探讨

目的：观察艾灸对类风湿关节炎大鼠的治疗作用及其机制。方法：将 100 只雄性Wistar大鼠随机分为5组。每组20只,除正常组外,其余4组大鼠制备类风湿关节炎模型。造模成功后,正常组和模型组不予任何治疗。艾灸组予艾条悬灸;香烟组予香烟悬灸,艾油组予艾叶精油穴位涂抹。连续治疗15d 后,比较各组大鼠体重、趾围、胸腺指数及脾指数变化,免疫组化方法检测大鼠关节滑膜中Fas/FasL 蛋白的表达。结果：艾灸组大鼠体重增加,关节肿胀减轻,胸腺指数提高、脾指数下降,关节滑膜中 Fas/FasL 蛋白的表达增加。在改善上述指标方面,艾灸组、香烟组较艾油组明显;艾灸组在Fas/FasL 蛋白表达方面优于香烟组。结论：艾灸治疗能显著改善大鼠类风湿关节炎症状,调节关节滑膜中 Fas/FasL 蛋白的表达,诱导滑膜细胞凋亡,这可能是艾灸发挥温通作用的有效机制之一。     

不同剂量弗氏完全佐剂对类风湿关节炎模型大鼠复制的影响

目的观察不同剂量的弗氏完全佐剂对类风湿关节炎(Rheumatoid arthritis,RA)模型复制的影响,探讨RA模型复制中弗氏完全佐剂的最佳注射量,以期为RA的实验研究提供较好的模型复制方法。方法采用"病证结合"复合佐剂性关节炎模型复制方法,即"风、寒、湿"环境因素+弗氏完全佐剂的模型复制方法,观察不同注射量的弗氏完全佐剂对RA模型复制的影响。结果 0.1mL模型复制组有自愈的趋势;0.15mL模型复制组大鼠体质量、跖围改变呈进行性下降趋势,X线可见骨质破坏情况较贴近临床患者骨质的改变;0.2mL模型复制组骨质呈粉碎性破坏。结论 0.15mL注射量可能是RA模型复制中的最佳注射量。     

Effect of mild-warm moxibustion on fatigue,immune state and quality of life in sub-health population

Objective

To observe the effect of mild-warm moxa stick moxibustion on fatigue, immune state and quality of life (QOL) in sub-health population.

Methods

A total of 120 cases were randomly allocated into a moxibustion group ((n=60) and a Chinese patent medicine (CPM) group (n=60). People in the moxibustion group were intervened with mild-warm moxa stick moxibustion, once a day; while people in the control group took oral Bu Zhong Yi Qi Wan (Spleen/stomach-supplementing and Qi-boosting Pill), 3 doses a day. Two months made up a course of treatment. The fatigue, immune state and QOL were then observed after one treatment course, followed by a 12-month follow-up.

Results

A total of 115 cases completed the clinical trial. After intervention, the fatigue scores, immune parameters and QOL scores were significantly increased in both groups, showing statistical significances (P<0.05). There were between-group significant differences in fatigue score, levels of immunoglobulin M (IgM) and IgG, natural killer (NK) cell activity and QOL score (P<0.05). After the 12-month follow-up, there were still significant between-group differences in fatigue score, physical health, psychological, social relationships and overall perception of QOL and overall perception of health (P<0.05).

Conclusion

Mild-warm moxibustion can markedly improve the fatigue, immune state and QOL in sub-health population.
