Objective To probe into the impacts on the expression of vascular endothelial growth factor （VEGF） in ischemic brain tissue treated with cluster puncture on scalp acupoints in rats, Methods 128 rats were randomized into pseudo-operation group, model group, scalp-needling group and cluster-needling group, In scalp-needling group, penetration method was used on the focal side from Bǎihuì （百会 GV20） to Qǔbīn （曲鬓 GB7）, and in cluster-needling group, penetration method was used on both sides from GV20 to GB7, and a common needling on GV 20. Needles were punctured 2 mm in depth, constantly rotated for 10min, retained for 2 h. Immunohistrochemical method was applied to determine VEGF expression and microvessel density （MVD）. Results With the intervention of cluster puncture on scalp acupoints, VEGF： expressions on every time-spot after ischemia were enhanced apparently, superior to those in scalp-needling group. On the three time-spots of the 7^th, 14^th and 21^st days, MVD was increased after cluster puncture on scale acupoints, superior to those in scalp-needling group. Conclusion Cluster puncture on scalp acupoints up-regulated VEGF expression and promoted regeneration of microvessel.
Objective To probe into the impacts on the therapeutic effects and endothelin （ET） in multi-infarct dementia （MID） treated with cluster pricking on head points.Methods 60 cases of MID were randomized into acupuncture group and western medicine group,treated with cluster pricking on head points and huperzien A tablet respectively.Plasma ET lever,HDS,ADL and CNFDS （clinical neurological functional defect scoring） were determined before treatment,and the statistical analysis showed that there were no significant difference （P〉0.05）.Results In 8-week treatment,ET level in both groups were decreased,but it was decreased much more obviously in acupuncture group,indicating significant difference in the statistical comparison （P〈0.05）.The scores of HDS and ADL were all up in acupuncture and western medicine groups,but the significant statistical difference was obtained in the comparison between acupuncture group and western medicine group （P〈0.05）.In acupuncture group,the result of CNFDS was much down comparing with that before the treatment,indicating significant difference （P〈0.05）;but in western medicine group,there was no significant difference in CNFDS before and after treatment （P〉0.05）,suggesting that acupuncture reduces CNFDS of MID patient,neither for western medicine.Conclusion Cluster pricking on head points improves the intelligence of MID patient,reduces ET level and grades up HDS and ADL,moreover,it reduces CNFDS of MID patients and releases the symptoms.
