RESUMO
OBJECTIVE@#To compare the clinical therapeutic effect between deep needling at Xiaguan (ST 7) with round sharp needle combined with plum-blossom needle and conventional acupuncture in patients with trigeminal neuralgia (TN) of wind and heat, and explore its mechanism.@*METHODS@#A total of 60 patients with TN of wind and heat were randomized into an observation group (30 cases) and a control group (30 cases). In the observation group, deep needling with round sharp needle was applied at Xiaguan (ST 7), and tapping with plum-blossom needle was applied at Yangbai (GB 14), Quanliao (SI 18), Dicang (ST 4), Sibai (ST 2), etc. of affected side. In the control group, conventional acupuncture was applied at the same acupoints selected in the observation group. The treatment was given once a day, 5 times a week for 4 weeks in the both groups. Before and after treatment, the scores of short-form McGill pain questionnaire (SF-MPQ), TCM syndrome, patient global impression of change (PGIC) and comprehensive symptom were observed, the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), vasoactive intestinal peptide (VIP) and β-endorphin (β-EP) were detected, and the adverse reaction was observed in the both groups.@*RESULTS@#After treatment, the scores of PRI, PPI, VAS, TCM syndrome, PGIC and comprehensive symptom and the serum levels of IL-6, TNF-α and VIP were decreased compared before treatment in the both groups (@*CONCLUSION@#Deep needling at Xiaguan (ST 7) with round sharp needle combined with plum-blossom needle can effectively treat the trigeminal neuralgia of wind and heat and relieve pain, its therapeutic effect is superior to conventional acupuncture. The mechanism may be related to the regulation of serum IL-6, TNF-α, VIP and β-EP.
