Objective To observe the clinical curative effect of Xintong decoction in treating unstable angina pectoris(UAP) and impact on serum matrix metalloproteinase 2(MMP-2) of patients with syndrome of phlegm and blood stasis,qi stagnation and obstruction of heart meridian,and probes into its intervention mechanism on UAP.Method Patients were randomly divided into treatment group(30 cases,treated with Xiaotong decoction + routine western medicine) and control group(30 cases,treated with routine western medicine).The course was four weeks.The clinical curative effect was observed and serum MMP-2 before and after treatment was detected.Results TCM syndrome score,angina pectoris,nitroglycerin discontinue rate,serum concentration of MMP-2 in the treatment group were significantly better than the control group.Conclusion Xintong decoction has good curative effect in treating UAP.It can reduce the serum level of MMP-2 of patients with UAP,so as to slowing the progress of plaque and stabilizing plaques.

AIM: To explore the action of Zisheng Qingyang Tablet for improving left ventricle hypertrophy of essential hyertension's traditional Chinese medicine syndromes and for lowering blood pressure(BP). METHODS: There were 60 patients, whose syndrome differentiation typing(SDT) was the yin-deficiency and yang-hyperactivity, the deficiency of heart-qi with dizziness caused by wind accompanied cardiac hypertrophy(essential hypertension left ventricle hypertrophy). The 60 patients were randomly divided into treating group and comtrol group each group with 30 patients. 4 months was one course of treatment. Pre-and post-therapy, the total scores of each group, the individual syndrome's scores of each group and the levels of BP were marked. RESULTS: After treating, the TCM syndromes of two groups were relieved. The total scores and improvements of TCM syndromes were markedly higher than that of the control group, and the significance especially displays on relieving main symptoms, such as dizziness, headache, chest distention and palpitation(P0.05). CONCLUSION: Zisheng Qingyang Table can obviously improve TCM syndromes, The effects especially exist in relieving the main symptoms as follows: dizziness, headache, chest distention, palpitation. The action of Zisheng Qingyang Tablet and captopril for lowering BP is alike.

Objective To observe the intervention effects of Xintongfang on the expression of P-selectin (PS), P-selectin glycoprotein ligand-1 (PSGL-1), platelet-leukocyte aggregates (PLA) and platelet-monocyte aggregates (PMA) in patients of coronary heart disease with carotid artery plaque. Methods Sixty patients were randomly divided into Xintongfang group and the control group, with 30 cases in each group. Xintongfang group was given Xintongfang, the control group was given aspirin and atorvastatin calcium for two months. The expression of PS, PSGL-1, PLA and PMA were tested by flow cytometry before and after treatment. Results The expression of PS, PSGL-1, PLA and PMA in two groups were reduced (P<0.01). Xintongfang group had more obvious effects on the expression of PLA and PMA than the control group (P<0.05). Conclusion Xintongfang can reduce the degree of inflammatory in patients of coronary heart disease with carotid artery plaque by inhibiting platelet-leukocyte interaction.

Objective To explore Wang Xingkuan’s rules of syndrome and treatment of chest blocking and heartache (Xiongbixintong).Methods Collection of professor Wang Xingkuan’s 267 consilia of patients with Xiongbixintong for outpatients. Chinese medicine terminology was regulated and Excelldatabase was established. Symptom, syndrome element, pathogenesis and treatment were statistically described by using Weka3.6 software, and Apriori algorithm was adopted for the main pathogenesis→treatment analysis of association rules.Results Symptoms include:chest pain, heart palpitations, shortness of breath, pale tongue (dark) red, etc. Syndrome elements include:in liver, and heart, and blood stasis, phlegm, qi stagnation, etc. The key pathogenesis is liver-heart imbalance, including stagnation of liver qi, heart and blood stasis, deficiency of heart qi-ying, disturbing heart-mind, etc. The principle of treatment is liver-heart Tongzhi, so the treatment is of“liver” with Shu gan-mu;treatment of“heart” contains freeing channels, eliminating phlegm and blood stasis, quiet the heart, replenishing qi-ying, etc. The main pathogenesis related credibility→treatment was higher than 0.50;with high reliability, the liver-heart imbalance→liver-heart Tongzhi was 0.71. Medication includes catharsis and tonic,“catharsis” to salvia, allium macrostemon, pseudo-ginseng, bupleurum, etc;“tonic” to white ginseng, ophiopogon japonicus, radix paeoniae alba, poria with hostwood, polygala tenuifolia, etc. Conclusion “Xintongzhigan, liver-heart Tongzhi, catharsis and tonic” is Wang Xingkuan’s thoughts and experience in treating Xiongbixintong.

ObjectiveTo study the medication rules of Professor. WANG Xingkuan and inherit his academic experience in the treatment of chest stuffiness and pain with the aid of the Traditional Chinese Medicine Inheritance Computing Platform V3.0 （TCMICS V3.0）. MethodThe original medical records of patients with angina pectoris in coronary heart disease （CHD） diagnosed and treated by Prof. WANG in the outpatient department of Hunan University of Chinese Medicine from 2017 to 2020 were collected and entered into the TCMICS V3.0. The rules of prescriptions and drugs were analyzed by the software. ResultA total of 1 044 prescriptions of Prof. WANG for the treatment of chest stuffiness and pain were collected. Most of the drugs were sweet and bitter in flavor and mainly acted on the lung meridian， followed by heart， spleen， liver， stomach， and kidney meridians. Among the prescriptions， Shengmaisan was the most commonly used classic prescription， and Xintongling No. Ⅲ was the top experienced prescription. High-frequency drugs mainly included Ophiopogonis Radix， Pinelliae Rhizoma， Salviae Miltiorrhizae Radix et Rhizoma， Trichosanthis Pericarpium， Coptidis Rhizoma， Schisandrae Chinensis Fructus， and Bupleuri Radix. The common doses of drugs were 3， 5， 10， and 15 g. The analysis of formulation rules revealed 129 combinations of common drugs， 58 combinations with confidence > 0.99， and the core drugs of common syndromes. Six core drug combinations were obtained by drug clustering. ConclusionProfessor WANG treats chest stuffiness and pain based on syndrome differentiation following the principles of benefiting Qi， nourishing Yin， eliminating phlegm， resolving stasis， soothing liver， and promoting bile secretion， reflecting his academic idea of "regulation of multiple organs and comprehensive treatment". The core prescriptions can be used for reference by clinical practitioners， but further clinical and experimental studies are still needed to verify their efficacy.
