The mechanism of the eletrochemiluminescence of DHDS is discussed and the method is applied to detect the content of DHDS in tablets.

Methods: 93 patients suffering from vascular dementia were randomly divided into three groups, the combination of intravascular He-Ne laser irradiation with electroacupuncture group ( 31 cases) and the medicine group ( dihydroergotoxine, DHET, 31 cases).

方法：将93例VD患者按区组随机法分为激光合电针组、电针组和药物组（氢化麦角碱，DHET），每组31例。

It indicates that electroacupuncture can promote the ability of learning and memory and enhance AChE activity of brain in rats of vascular dementia, and the therapeutic effect of electroacupuncture is better than that of DHET.

而电针组又高于药物组（P<0.05），说明电针能改善VD大鼠学习记忆能力，提高脑AChE的含量并使之重新分布，其作用优于DHET。

Conclusions It indicates that electroacupuncture therapy can promote the ability of learning and memorizing and enhance the content of AchE in the brain of VD. Its therapeutic effect is better than DHET. 〔

结论电针能改善VD大鼠学习记忆能力，提高脑AchE含量并使之重新分布，其作用优于DHET。

Objective: To assess the efficacy of dihydroergotoxine ( DHET) in treatment of vascular dementia ( VD).

目的：观察氢化麦角碱（DHET）治疗脑血管性痴呆（VD）的临床疗效。
