ABSTRACT

OBJECTIVES: To observe the clinical efficacy of acupoint application in treating postherpetic neuralgia(PHN) with qi stagnation and blood stasis, and its effects on serum inflammatory factors and 5-hydroxytryptamine (5-HT) in patients. METHODS: A total of 136 PHN patients were randomly divided into an observation group (68 cases, 6 case dropped out) and a control group (68 cases, 5 cases dropped out). In the observation group, the combination of swelling-reducing and pain-relieving patches and acupoint application with herbal powder was used at bilateral Sanyinjiao (SP 6), Shenque (CV 8) and ashi points. Sanyinjiao (SP 6) was applied for 30 min per session, once every 7 days; and Shenque (CV 8) and ashi points were applied for 6-8 h per session, once every 1 day. In the control group, mecobalamin injection was administered at Jiaji (EX-B 2) corresponding to the neural segments governing the painful area, 1 mL per injection, once a day. Each treatment course consisted of 7 days, 4 treatment courses were required in both groups. The visual analog scale (VAS) score for pain, 36-item short form health survey (SF-36) score, traditional Chinese medicine syndrome score, and the serum levels of inflammatory factors (monocyte chemoattractant protein-1 [MCP-1], interleukin-6 [IL-6], tumor necrosis factor-alpha [TNF-α]) and 5-HT were compared in the patients of the two groups before and after treatment, and the clinical efficacy was evaluated. RESULTS: After treatment, the VAS scores, traditional Chinese medicine syndrome scores, serum MCP-1, IL-6, TNF-α, and 5-HT levels were decreased compared with those before treatment in both groups (P<0.05), and the results in the observation group were lower than those in the control group (P<0.05). The SF-36 scores were increased compared with those before treatment in the two groups (P<0.05), and the result in the observation group was higher than that in the control group (P<0.05). The total effective rate of the observation group was 74.2% (46/62), which was higher than 52.4% (33/63, P<0.05) of the control group. CONCLUSIONS: The combination of swelling-reducing and pain-relieving patches and acupoint application with herbal powder has shown better efficacy in treating PHN with qi stagnation and blood stasis, which can significantly alleviate patients symptoms, improve their quality of life, and reduce serum levels of MCP-1, IL-6, TNF-α, and 5-HT.
