[Effect of electroacupuncture at "Shenmen"(HT7) and "Sanyinjiao"(SP6) on energy metabolism in paraventricular nucleus of hypothalamus of insomnia rats].

Objective: To observe the effect of electroacupuncture(EA) at "Shenmen"(HT7) and "Sanyinjiao"(SP6)on energy metabolism in paraventricular nucleus (PVN) of hypothalamus in insomnia rats, so as to explore its mechanism underlying improvement of insomnia.

Methods: A total of 66 SD rats (half male and half female) were randomized into 3 groups：normal control, model and EA groups(＝22 per group). The insomnia model was established by binding the rat for at least 4 h (step increase of 30 min per day), once daily for 15 days.

[Discussion on the constructing principle of syndrome differentiation system according to meridian and collateral theories].

According to the meridian and collateral theories in the Internal Classic, the authors proposed that the construction of the syndrome differentiation system with science characteristics of acupuncture and moxibustion should follow the principle of systemic structure and physiological function. The establishment of the whole frame structure of syndrome differentiation system according to meridian and collateral theories should base on the principle of systemic structure and the establishment of symptom of each syndrome should base on the principle of physiological function.

[Effect of electroacupuncture at Shenshu (BL 23) and Zusanli (ST 36) on the event-related potentials of chronic fatigue syndrome].

Objective: To observe the effective mechanism of electroacupuncture for chronic fatigue syndrome (CFS).

Methods: The dynamic detection of chronobiology was used to test the event-related potentials in 20 healthy subjects and 20 CFS patients. P3a and P3b latencies at 4 equidistant time points (8:00, 14:00, 20:00, 2:00) within 24 hours were collected and analyzed.
