基于隐结构模型和频繁项集的针刺治疗慢性前列腺炎辨证取穴规律OA北大核心CHSSCDCSTPCD

Objective:To mine the acupoint selection pattern in the acupuncture for chronic prostatitis and provide clues for clini-cal treatment of this disease.Methods:The articles about acupuncture for treating chronic prostatitis were retrieved from the China National Knowledge Infrastructure(CNKI)and Chinese Citation Database(CCD).A case library was built,containing symptoms,syndromes,and acupoint prescriptions.The latent structure model and frequent item set were employed to mine the acupoint selec-tion pattern in the acupuncture for chronic prostatitis.Results:A total of 64 articles were included,involving 91 acupoints and 248 symptoms.The high-frequency acupoints included Sanyinjiao(SP6)and Zhongji(CV3),and the high-frequency symptoms included tongue petechiae and ecchymosis,yellow greasy tongue coating,prostatorrhoea,and urgent urination.A latent structure model was built,which indicated that the main syndromes of chronic prostatitis included dampness-heat pouring down and kidney yang defi-ciency.Four frequent item sets each of symptom-acupoint and symptom-syndrome-acupoint were mined out.A representative symp-tom-acupoint set was urgent urination+prostatorrhoea+impotence+premature ejaculation+Shenshu(BL23)+Zusanli(ST36).A representative symptom-syndrome-acupoint set was frequency of urination+urgent urination+yellow greasy tongue coating+prosta-torrhoea+tongue petechiae and petechistasis+stasis and obstruction of dampness and heat+Sanyinjiao(SP6)+Huiyin(CV1).The results suggested that acupoints can be selected according to the syndrome identified based on corresponding symptoms.Con-clusion:In the treatment of chronic prostatitis,Sanyinjiao(SP6),Zhongji(CV3),and Guanyuan(CV4)can be taken as the main acupoints for acupuncture.The acupoints can eb selected according to the syndromes.The findings of this study can provide a refer-ence for the clinical treatment of chronic prostatitis.
