Clinical Study On Female Acne With Yin-Three-Needle Technique

Objective:To observe the clinical effect of Yin-Three-Needle Technique on female acne, and preliminary estimate the possible mechanism by studying the comparisons of acne lesions and effective rates from two groups.Methods:Randomized 60 female acne patients into Yin-Three-Needle group and control group. According to the differentiation standards of Chinese Medicine: there were 18 cases on Chong-Ren disorders,17 on Wind-Heat of Lung Channel, 18 on damp-heat syndrome,7 on dampness in total.27 cases complained of irregular menstruation, constituted 45% of 60 cases. Acne lesions were graded by GAGS (The Globe Acne Grading System), which is a quantitative scoring system in which the total severity score is derived from summation of six regional sub scores. The Yin-Three-Needle group received Yin-Three-Needle and Hand-three-Needle; while the control group received only Hand-three-Needle every other day, avoiding the menstruation week, collected severity scores of lesions after the 6th visit and the 12th visit. The follow-up visit was set on one month later. All data were analyzed under PASW Statistics 18.0. Results:Yin-Three-Needle group ended with effective of 93.33%, while control group was of 86.67%, indicating statistical significance (P<0.05). During follow-up visit, there were one recurrent patient in Yin-Three-Needle group, and 3 in control group. Their lesion scores showed a statistical significance (P<0.05). Compared the effective among the 4 differentiation types, Chong-Ren disorders and Wind-Heat of Lung Channel were 100%, while damp-heat syndrome was 87%, and dampness was 20% in. Yin-Three-Needle group; Chong-Ren disorders and Wind-Heat of Lung Channel were 100%, while damp-heat syndrome was 90%, and dampness was 25% in control group. Statistics showed only Chong-Ren disorders indicated statistical significance between two groups. Intra-class comparison of the Yin-Three-Needle group showed Chong-Ren disorders and Wind-Heat of Lung Channel were superior to other syndromes on effective rates, while control group only displayed a superiority in Wind-Heat of Lung Channel. Among cases complained with irregular cycles, their effective was 85.71% in Yin-Three-Needle group, and 76.92% in control group. This difference were proven statistical significance by PASW Statistics 18.0. The effective among regular cycle patients were almost the same.Conclusion:Two groups were both effective in lowering lesion scores, while the Yin-Three-Needle group lowered the scores more quickly, with less recurrence cases, indicating the Yin-Three-Needle group are capable in shorten the treatment cycle with a more lower lesion scores. What's more, Yin-Three-Needle group achieved even better effective in irregular menstruation female than the control group. Yin-Three-Needle is an efficient, time-saving, and safe therapy in treating female acne.
