我们曾报道:内脏伤害性传入冲动可以达到大脑皮层内脏大神经投射区,引起内脏痛放电和诱发电位,电针“内关”穴或正中神经可以抑制内脏大神经诱发的皮层内脏痛放电和诱发电位。为了进一步确定大脑皮层与针刺“内关”穴抑制内脏痛的关系,本文对“内关”传入信号是否到达大脑皮层,皮层有无“内关”投射区,刺激皮层“内关”投射区对皮层内脏痛放电有无影响作了探讨。

在11例豚鼠离体灌流的右心室乳头肌进行实验,将玻璃微电极插入乳头肌细胞内记录跨膜电位。气功师于距离标本0.5～1.5米处发放外气,记录发放气功外气5′、10′、15′、以及停止外气5′、10′、15′时心肌细胞的动作电位。心肌细胞实验结果用微电脑系统进行即时分析,由 BMC 型行列式打印机打印。本实验结果表明:气功外气可影响豚鼠右心室乳头肌动作电位的幅值和时程,表现在使APA降低,ERP和APD均缩短。这些变化在统计学上有高度显著的意义。气功外气对RP影响较少而对0相去极化Vmax无影响。非气功师发放的模拟外气无此作用。曾在6例进行重复试验,结果与原来数据相似。表明气功外气干扰了心肌细胞去极化和复极化过程。至于影响此过程的机理如何和涉及那些离子通道,有待进一步探讨。

目的 观察肾炎舒颗粒对早期糖尿病肾病患者尿足细胞标志蛋白及其相关指标的变化，探讨其抗蛋白尿及改善肾小管功能的机制。方法 80例早期糖尿病肾病患者随机分为观察组44例和对照组36例。两组均给予糖尿病常规治疗，观察组在此基础上加服肾炎舒颗粒治疗，5 g／次，3次／d，疗程为6个月。分别于治疗前及治疗6个月后检测两组尿足细胞标志蛋白（PCX）、尿白蛋白肌酐比值（ACR）、尿 N-乙酰-β-D 氨基葡萄糖苷酶（NAG）、尿中性粒细胞明胶酶相关脂质转载蛋白（NGAL）、尿可滴定酸、尿铵离子水平。结果治疗6个月后，观察组尿PCX、ACR、NAG、NGAL 较治疗前显著减低（P 均＜0．01）；与对照组相比，观察组治疗后尿 PCX、ACR、NAG、NGAL明显减少（P 均＜0．05）。结论肾炎舒颗粒可能通过保护肾脏足细胞达到降低早期糖尿病肾病患者尿蛋白的作用，同时对损伤的近端肾小管具有保护作用。 [ABSTRACT FROM AUTHOR]
