Objective To investigate the effect of Shanzha Xiaozhi capslue on intima-media thickness(IMT) and plaques score of carotid artery in patients with non-acute phase coronary heart disease and traditional Chinese medicine(TCM)syndrome of phlegm and blood stasis. Methods A prospective study was conducted to carry out a research on 102 patients with non-acute phase coronary heart disease and TCM syndrome of phlegm and blood stasis. They were randomly divided into two groups:a control group(50 cases)treated with conventional western medicine alone and a observation group(52 cases)which was treated by both conventional western medicine and Shanzha Xiaozhi capslue(the main TCM ingredients:Shanzha,Dahuang)0.7 g,3 times a day,the therapeutic course being 6 months in both groups. The cardiocerebral vascular incidences of the two groups were observed,in the mean time,the carotid artery IMT and plagues score were registered,the scores of phlegm stagnation syndrome and blood-stasis syndrome were measured,adverse reaction was observed and compared in both groups before and after treatment. Results After treatment,the occurrence of major adverse acute cardiovascular and cerebrovascular events in observation group were reduced significantly compared with those in the control group(5.77%vs. 20.00%,P<0.05). The IMT and plaques score of carotid artery and the scores of phlegm stagnation syndrome and blood-stasis syndrome were all decreased obviously compared to those before treatment,and the effect was more remarkable in the treatment group〔IMT of carotid artery(mm):0.80±0.13 vs. 0.95±0.12,the plaques score:1.35±0.65 vs. 1.75±0.88, phlegm syndrome score:20.98±6.42 vs. 35.55±9.22,blood-stasis syndrome score:23.23±5.12 vs. 28.95±6.38, P<0.05 or P<0.01〕. Abdominal pain appeared in 2 patients of observation group without other adverse reactions. Conclusion Shanzha Xiaozhi capsule can stabilize atherosclerotic plaque and reduce the occurrence of acute adverse cardiocerebral vascular events in patients with non-acute phase coronary heart disease and phlegm and blood stasis syndrome possibly by removing phlegm and blood stasis to decrease the IMT and plaques score of carotid artery.

OBJECTIVE: To explore the mechanism of Tiaozhong Granule (TZG), a compound traditional Chinese herbal medicine, in treating rats with mixed reflux esophagitis. METHODS: Fifty-eight SD rats were randomly divided into untreated group (n=12), sham-operated group (n=10), TZG-treated group (n=12), Banxia Xiexin Decoction (BXXXD)-treated group (n=12) and cisapride-treated group (n=12). Mixed reflux esophagitis was induced by esophago-duodenum end-to-side anastomosis. Four weeks later, the rats were orally administered twice daily for 12 days. Pathological changes of esophagus mucous membrane were observed by using HE staining. The expressions of proliferating cell nuclear antigen (PCNA) and p53 in the esophagus tissue were detected by immunohistochemical SABC method. Spectrophotometric method was used to detect the content of malondialdehyde (MDA) and the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in serum. RESULTS: Compared with the untreated group, pathological changes of esophagus mucous membrane were relieved in different degrees in TZG-treated group, BXXXD-treated group and cisapride-treated group. Content of MDA and expressions of PCNA and p53 were obviously decreased in the three treated groups (P<0.01), and the activities of SOD and GSH-Px were significantly increased in the three treated groups (P<0.05, P<0.01). TZG had better effects than cisapride in decreasing the content of MDA and increasing the activities of SOD and GSH-Px (P<0.05). TZG was better in aspect of reducing the expressions of PCNA and p53 than BXXXD and cisapride tablets (P<0.05). CONCLUSION: Tiaozhong Granule can treat mixed reflux esophagitis in rats, and its action mechanisms may be associated with decreasing the expressions of PCNA and p53 in esophagus mucous membrane, reducing the content of MDA and increasing the activities of SOD and GSH-Px in serum.
