[Maximal Frequent Association Patterns between Symptoms of Coronary Heart Disease Patients with Blood Stasis Syndrome and Medication Constitutions].

A total of 121 medical cases concerning treating coronary heart disease (CHD) pa- tients with blood stasis syndrome (BSS) by Chinese Medicine were collected to establish a database for CHD patients with BSS. By using data mining authors tried to explore inherent laws of its symptoms and medication of Chinese Medicine, and to probe maximal frequent association patterns between its symp- toms and medication constitutions. Of the 121 medical cases, chest pain, chest stiffness, and headache were their common symptoms. Compatibilities of blood-activating drugs, stasis-resolving drugs, and qi- promoting drugs were most commonly used. The association between symptoms and compatibilities con- stituted a most often seen maximal frequent association pattern, which reflected an idea of treating both principal and subordinate symptoms.

[Analysis on acupoint selection rules for impotence treated with acupuncture and moxibustion in ancient based on data mining technology].

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.

Correlations between Phlegm Syndrome of Chinese Medicine and Coronary Angiography: A Systematic Review and Meta-Analysis.

Phlegm is one of the most common patterns of coronary artery disease (CAD) in Chinese medicine. Our research was aimed at investigating the association between phlegm syndrome of CAD and coronary angiography (CAG) by meta-analysis. According to inclusion criteria, a total of 30 studies involving 5,055 CAD patients were included. The meta-analysis showed that phlegm syndrome patients were prone to multivessel disease (28 studies, OR = 1.53, 95% CI, 1.24 to 1.88, P < 0.01) and higher Gensini score (2 studies, OR = 5.90, 95% CI, 1.86 to 9.94, P = 0.004), but not obviously relevant to severe stenosis (≥75%) of coronary arteries (13 studies, OR = 1.20, 95% CI, 0.63 to 2.27, P = 0.57). We concluded that the coronary arteries lesions of CAD patients with phlegm syndrome were more severe than those with nonphlegm syndromes. Phlegm syndrome should, therefore, be regarded as a dangerous pattern of CAD with worse prognosis.
