电针配合神经生长因子对脑缺血大鼠学习记忆能力的影响

Objective To observe the effect of nerve growth factor(NGF)and electro-acupuncture(EA) on learning and memory in rats with cerebral ischemia.Methods An experimental model of cerebral ischemiareperfusion was established in 40 rats,who were then randomly divided into a model group,a sham operated group,a NGF group,an acupuncture group and a NGF plus acupuncture group.Three weeks were allowed for the recovery of the blood-brain barrier lesion caused by ischemia-reperfusion before intravenous injection of NGF(10μg/kg,once daily for 15 days)via the vena caudalis.In the two acupuncture groups,this was administered in combination with EA at the Baihui(DU20)and Yamen(DU15)acupoints(frequency 100 Hz,2 mA,20 min/time,once daily for 15 days).Morris' water maze test was used to assess any changes in spatial learning and memory abilities.Results The ischemic rats showed significant learning and memory disorders compared with the sham-operated group.In the NGF group,the rats' learning and memory abilities did not impmve significantly compared with the model group and the EA group.Significantly better learning was observed in the NGF+EA group compared with the model group,the EA group and the NGF group.Conclusion NGF combined with EA can improve the learning and memory abilities of rats with learning and memory dysfunction caused by cerebral ischemia-repedusion.     

浮针疗法治疗肱骨内上髁炎30例临床观察

目的:比较浮针疗法与常规针灸疗法治疗肱骨内上髁炎的疗效差异。方法:将60例患者随机分为治疗组和对照组各30例。治疗组采用浮针疗法,对照组采用常规针灸疗法,均隔日治疗1次,每周3次,6次为1个疗程。比较2组患者治疗前后疼痛视觉模拟量表(VAS)评分,并评定2组疗效。结果:2组患者VAS评分均较治疗前降低(均P0.01),且治疗后治疗组低于对照组(P0.01);治疗组愈显率为60.0%,总有效率为93.3%,均优于对照组的33.3%、73.3%(均P0.05)。结论:浮针疗法治疗肱骨内上髁炎疗效确切,具有明显的止痛效应,且疗效优于常规针灸疗法。

基于五脏理论针灸辨治鼻鼽

《素问·脉解》中首次提出"鼻鼽",变应性鼻炎、血管运动性鼻炎、嗜酸性粒细胞增多性非变应性鼻炎等可归属为此范畴,与"心、肝、脾、肺、肾"五脏功能失调均密切相关。临床采用中药、针灸等治疗,疗效颇佳。辨证当先从八纲辨表里、寒热、虚实,再辨病性,最后辨脏腑病症或脏腑兼病症。临床多见素体不足之虚证、寒证,亦可见外邪初犯之表证、热证、实证;外邪多责于春之风邪、秋之燥邪和冬之寒邪,气虚、阳虚、津亏者多见;五脏以肺、脾、肾为主,与心、肝亦相关。临床治疗补虚为要、泻实为辅。针灸应基于五脏相关理论,益气升阳穴加局部取穴辨证加减,明辨缓急,分期论治;重用灸法,扶正祛邪;针刺调神,形神兼治;穴位埋线,长效刺激。气血冲和、形神俱安,邪乃无处可犯,病当自愈。
