[Effect of Acupuncture at Thirteen Evil Acupoints on Liver Function, and the Contents of Blood Ammonia and β-endorphin in Patients with Hepatic Encephalopathy].

OBJECTIVE

To observe the therapeutic effect of acupuncture at thirteen evil acupoints in patients with hepatic encephalopathy, and to explore its possible mechanism.

METHODS

Patients with hepatic encephalopathy were randomly divided into acupuncture group (=38) and western medicine group (=36). Patients in the western medicine group were treated by intravenous injection of aspartate ornithine and branched chain amino acids, and those in the acupuncture group were treated with acupuncture at thirteen evil acupoints on the basis of the western medicine. All the patients were treated for 1 week. The liver function and blood ammonia were measured by automatic biochemical analyzer. The changes of plasma β-endorphin were measured by enzyme-linked immunosorbent assay (ELISA).

RESULTS

Following the treatment, of the 36 and 38 hepatic encep-halopathy patients in the western medicine and acupuncture groups, 12 and 18 experienced a marked improvement in their symptoms, 13 and 16 were effective, and 11 and 4 invalid, with the effective rates being 69.4% and 89.5%, respectively. Compared with pre-treatment, the levels of serum aspartate aminotransferase, alanine aminotransferase, total bilirubin, and plasma β-endo-rphin and blood ammonia were significantly lower in both western medicine and acupuncture groups(<0.01), and the therapeutic effects of the acupuncture group were obviously superior to those of the western medicine group in the above mentioned indexes (<0.05, <0.01).

CONCLUSIONS

Treatment of acupuncture at thirteen evil acupoints combined with western medicine can enhance the curative effect of hepatic encephalopathy, improve patients' liver function and decrease the levels of plasma ammonia and β-endorphin.
