Based on the data mining technology, the rules of acupoint selection and prescription were analyzed for impotence treated with acupuncture and moxibustion in ancient recorded in Zhonghua Yidian. By taking "yangwei" and "yinwei" as the searching terms, the database of Zhonghua Yidian (the 5th edition) were retrieved and the relevant information of impotence, such as prescription provision, acupoints and use frequency were extracted. Using the software, e.g. Microsoft Excel and Weka 3.8.4, the rules of acupoint selection and prescription for impotence treated with acupuncture and moxibustion in ancient were analyzed. Fifty five provisions of acupoint prescriptions were in compliance with the requirements and screened. Of them, there were 17 compound prescriptions and the rest were the single-point prescriptions, with 24 acupoints involved. Regarding the use frequency of acupoints in treatment of impotence, the top 5 acupoints were Yingu (KI 10), Ququan (LR 8), Qichong (ST 30), Taichong (LR 3) and Rangu (KI 2). The cluster analysis found that Yingu (KI 10), Ququan (LR 8)-Qichong (ST 30), Taichong (LR 3)-Rangu (KI 2)-Xingjian (LR 2), and Mingmen (GV 4)-Zhongfeng (LR 4)-Yuji (LU 10)-Yanggu (SI 5) were formed the group prescriptions respectively. Multilayer correlation analysis discovered that the commonly used meridians were the liver meridian of foot-jueyin, the kidney meridian of foot-shaoyin, the stomach meridian of foot-yangming and the conception vessel. The acupoints selected were generally on the lower extremities, the abdomen and the upper extremities. Regarding the special points, the five-shu points and the convergent points were mostly involved. By the analysis on compound prescriptions, 3 patterns of acupoint combination were discovered, the prescription by taking Yingu (KI 10), Rangu (KI 2) and Zhongfeng (LR 4) as the key points, the one by taking Shenshu (BL 23) and Yanggu (SI 5) as the key points and the relevant fixed combination of 4 acupoints, including Taichong (LR 3), Xingjian (LR 2), Neiting (ST 44) and Xiangu (ST 43). By the analysis on the compound prescriptions, 3 common meridian combinations were found, including the combination with the kidney meridian predominated, the relevant fixed combination with the liver meridian and the stomach meridian and the one with small intestine meridian and the lung meridian.
