RESUMEN
<p><b>OBJECTIVE</b>To study the clinical effect of "Jin's three-needling" in the treatment of generalized anxiety disorder.</p><p><b>METHODS</b>Fifty-eight patients with generalized anxiety were randomly assigned to two groups equally, the medication group treated with anti-anxiety drugs and the acupuncture group with "Jin's three-needling". The treatment course was 6 weeks. The clinical effects were evaluated with Hamilton anxiety scale (HAMA), clinical global impression (CGI), and treatment emergent symptom scale (TESS) before treatment and at the end of 2nd, 4th, 6th week of the treatment course. The concentration of 5-hydroxytryptamine (5-HT) in platelet, and plasma levels of corticosterone (CS) and adrenocorticotropic hormone (ACTH) were measured with high performance liquid chromatography-electrochemical detection (HPLC-ED) method before and after treatment.</p><p><b>RESULTS</b>The clinical effects in the two groups were equivalent, while the adverse reaction found in the acupuncture group was less than that in the medication group (P < 0.05). The platelet concentration of 5-HT and plasma ACTH level decreased significantly in both groups after treatment with insignificant difference between the group (P < 0.05). The plasma CS level had no obvious change in the two groups after treatment as compared with that before treatment respectively.</p><p><b>CONCLUSION</b>"Jin's three-needling" shows similar curative effect on generalized anxiety to routine Western medicine but with less adverse reaction, which may be realized through regulating the platelet 5-HT concentration and plasma ACTH level.</p>
