Effect of Dazhu Hongjingtian Capsule on Unstable Carotid Plaque with Qi Deficiency and Blood Stasis Syndrome / 中国实验方剂学杂志

ABSTRACT

Objective: To discuss the effect of Dazhu Hongjingtian capsule to unstable carotid plaque (Qi deficiency and blood stasis syndrome), and its mechanisms in resisting oxidation, inflammation and thrombosis. Method: One hundred and twenty-three patients were randomly divided into control group (61 cases) and observation group (62 cases) by random number table. Patients in control group got aspirin enteric-coated tablets, 0.1 g/time, 1 time/day, and rosuvastatin calcium capsules, 10 mg/time, 1 time/day. In addition to the therapy of control group, patients in observation group were also given Dazhu Hongjingtian capsule, 4 grains/days, 3 times/days. And the outpatient follow-up was made once every 2 weeks for continued 16 weeks. Intima-media wall thickness (IMT), and number and size of plaque were detected by color Doppler ultrasound. And levels of triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL-C), low-density lipoprotein (LDL-C), superoxide dismutase (SOD), malondialdehyde (MDA), hypersensitive C reactive protein (hs-CRP), homocysteine (Hcy), matrix metalloproteinase-2 (MMP-2), MMP-9, tissue inhibitor of matrix metalloproteinase-2 (TIMP-2), platelet alpha granular membrane protein (GMP-140), P-selectin on surface of platelets (CD62 p), lysosome glycoprotein (CD63), and vascular pseudotumor factor (VWF) were detected. Qi deficiency and blood stasis syndrome were graded. Result: After treatment, IMT in observation group was thinner than that in control group, number of plaque was less than that in control group, and size of plaque was smaller than those in control group (PPPPConclusion: In addition to the treatment for resisting platelet and regulating blood lipid, Dazhu Hongjingtian capsule can lessen and reduce arterial speckle regulate lipid metabolism, ameliorate symptoms of traditional Chinese medical (TCM) syndrome, with effects in resisting oxidation, inflammation and thrombotic formation.
