[Acupoint selection and medication rules analysis for allergic rhinitis treated with acupoint application-based on data mining technology].

To make a systematic study on acupoints selection and medication rules for allergic rhinitis treated with acupoint application, literature regarding clinical researches on acupoint application for allergic rhinitis since 2000 has been retrieved; medication and acupoints involved were preprocessed and cluster analysis technique was applied to classify the data. As a result, a total of 37 pieces of literature were included, involving 27 types of herbs and 33 acupoints. The results showed Baijiezi (Brassica alba Boiss), Xixin (Radix et Rhizoma Asari), Gansui (Radix Kansui), Yanhusuo (Corydalis), Jiangzhi (Ginger juice) and Baizhi (Radix angelicae) constituted the main herb prescription, and the layer was increased along with frequency of use. Feishu (BL 13), Dazhui (GV 14), Shenshu (BL 23), Pishu (BL 20), Gaohuang (BL 43), Fengmen (BL 12) constituted the main acupoint prescription, which were clustered into 4 classes; Feishu (BL 13) and Dazhui (GV 14) constituted the first class; Pishu (BL 20) and Shenshu (BL 23) constituted the second class; the first and second class merged into the third class, Including Feishu (BL 13), Dazhui (GV 14), Shenshu (BL 23) and Pishu (BL 20); Gaohuang (BL 43) and Fengmen (BL 12) constituted the fourth class; the fourth class and the third class constituted the whole acupoint prescription. It was showed that for the allergic rhinitis treated with acupoint application, the medication was mainly epispastic herbs with pungent nature that belonged to the lung, spleen and kidney meridian, which presented the principle of simultaneous treatment of principal and subordinate symptoms; also the medication can be selected from core layer to supporting layer based on clinical needs; for the selection of acupoints, acupoints in lung and bladder meridian were mainly selected to assist exterior and resist the pathogenic qi, which could treat allergic rhinitis fundamentally by joint use with acupoints in soleen and kidney meridian.
