AIM:To explore the mechanisms of Kangxian Yixin Extract(Radix Codonopsis,Radix Astragali,Poria,Rhizoma Atractylodis macrocephalae,Radix et Rhizoma Salviae miltiorrhizae,Rhizoma Chuanxiong,Flos Carthami,Radix Paeoniae rubra,Herba Lycopi,Herba Leonuri) on ventricular remodeling after dilated cardiomyopathy. METHODS: Ventricular remodeling model was induced by giving Furazolidone in wistar rats for 8 weeks and survival rats were divided into 5 groups(14 rats each group) after another 8 weeks,all the rats were killed.The effects of Kangxian Yixin Extract on typeⅠand type Ⅲ collagen gene expression were determined with SP and RT-PCR methods.

Objective To investigate the effects of the Pingan qushi prescription on traditional Chinese medicine syndrome,adverse events,and compliance in young and middle-aged hypertensive patients.Methods One hundred thirty-two young and middle-aged patients with hypertension were selected and randomly divided into two groups.After elimination,64 cases were included in each group.For 2 months,the control group was treated with irbesartan tablets,and the observation group underwent the Pingan qushi prescription based on the control group.The blood pressure,curative effect,traditional Chinese medicine syndrome score,safety,adverse events,and prognosis-related indicators were compared between the two groups.Results The total effective rate of the observation group(96.88%,92.19%)was higher than that of the control group(82.52%,78.13%),and the difference was statistically significant(P = 0.005,P = 0.025).After 1 and 2 months of treatment,the blood pressure,syndrome scores,ALD,PRA,AngⅡ,and ET-1 in the observation group were lower than those in the control group,and the differences were statistically significant(all P<0.05).There was no sig-nificant difference in the incidence of adverse reactions between the two groups(P>0.05).There was no statistically significant difference(P>0.05)in the incidence of adverse events during treatment between the observation group(1.56%)and control group(10.94%).Conclusion The treatment of young and middle-aged community patients with hypertension undergoing the Pingan qushi pre-scription can further improve patients'symptoms,increase blood pressure control,promote prognosis improvement.

OBJECTIVETo study the effect of shensongyangxin capsule on myocardial remodeling and ventricular fibrillation characteristics in rat with coronary artery ligation.

METHODTwenty-three male rats were randomly divided into sham-group (n = 5), model group (n = 6), anmiodarone group (n = 6) and shensongyangxin capsule group (n = 6). Drugs were administrated after modeling of 2 days, lasting four weeks. Two dimensional and Doppler images were acquired by a 15 MHz high-frequency linear ultrasound transducer at 4 weeks after operation, and chest was opened to detect ventricular fibrillation threshold value and persistent time.

RESULTAfter administration of four weeks, echocardiogram was detected. Compared with model group, shensongyangxin capsule group diastasis interventricular septum thickness (IVSTd) and left ventricle diameter (LVDd) were significiently different between them (1.20 +/- 0.49) vs (0.78 +/- 0.08) mm and (6.77 +/- 1.34) vs (7.95 +/- 0.92) mm, (P < 0.01 and 0.05); echocardiogram result had no difference in amiodarone and model groups (P > 0.05). LVMI measured by practicion was different between shensongyangxin capsule and model groups: (17.12 +/- 1.91) vs (18.95 +/- 1.41) g x m(-2), (P < 0.05), while amiodarone group had no difference compared with model group. Electrophysiology was used to detect ventricular fibrillation threshold value and 1-5, 6-10, 11-15 V three stages' ventricular fibrillation threshold persistent time were significiently different among each group (P < 0.01), 16-20 V stage's ventricular fibrillation persistent time were also different among each group (P <0.05). Sample "average ranks" showed ventricular fibrillation threshold value of amiodarone group and shensongyangxin capsule group were four times than model group; and amiodaron group had best effect of holding-back ventricular fibrillation persistent time.

CONCLUSIONThe coronary artery ligation can result in myocardial remodeling by increasing volume load, and at the same time influencing electrophysiology function of heart. Amiodaron elevated ventricular fibrillation threshold of heart, this effect maybe relate to influencing many ion channels of myocardial cellular membrane; shensongyangxin capsule also elevate ventricular fibrillation threshold of heart, this effect maybe also relate to influencing many ion channels of myocardial cellular membrane, and on the other hand this effect maybe relate to hold-back ventricular remodeling after coronary artery was ligated, accordingly improve electrophysiological base material of heart.

OBJECTIVE To observe the efficacy and safety of ticagrelor combined with Compound xueshuantong capsules in the treatment of unstable angina pectoris. METHODS Totally 120 patients with unstable angina pectoris with deficiency of Qi and Yin combined admitted to Sanmenxia Hospital of Traditional Chinese Medicine from January 2021 to December 2022 were randomly divided into clopidogrel group （group A）， ticagrelor group （group B） and combined medication group （group C）， with 40 patients in each group. In addition to conventional treatment， group A was given clopidogrel orally； group B was given ticagrelor orally； group C was given ticagrelor and Compound xueshuantong capsule orally. After 12 weeks of treatment， the clinical efficacy， frequency of angina attacks， coagulation function indicators， cardiac function indicators， traditional Chinese medicine syndrome efficacy， and the incidence of adverse cardiovascular events and bleeding incidence were evaluated in the 3 groups. RESULTS The total effective rates of group A， group B and group C were 77.5%， 85.0% and 90.0%， respectively. The incidence of adverse cardiovascular events and bleeding events were 7.5%， 7.5% and 5.0% in the respective groups， with no statistically significant difference （P＞0.05）. The frequency of angina attacks， duration of angina attacks and duration of dyspnea were significantly reduced or shortened in all 3 groups after treatment compared to before treatment （P＜0.05）. The frequency of angina attacks in group C was significantly lower than that in groups A and B after treatment （P＜0.05）. The levels of fibrinogen （FBG） and D-dimer in all 3 groups were significantly lower after treatment compared to before treatment （P＜0.05）； group A had significantly higher levels of FBG and D-dimer compared to group B and C （P＜0.05）. The left ventricular end-diastolic diameter and left ventricular end-systolic diameter in all three groups were significantly shorter after treatment， and the left ventricular ejection fraction was significantly higher compared to before treatment （P＜0.05）， but there were no statistically significant differences among those groups （P＞0.05）. The total effective rates of traditional Chinese medicine syndrome efficacy in groups A， B and C were 67.5%， 80.0% and 87.5%， respectively， with group C being significantly higher than group A （P＜0.05）. CONCLUSIONS In addition to conventional treatment， ticagrelor combined with Compound xueguantong capsules can more significantly reduce the frequency of angina attacks in patients with unstable angina pectoris， reduce the levels of FBG and D- dimer， improve traditional Chinese medicine syndrome efficacy， and do not increase the risk of bleeding.
