Abstract
BACKGROUND Atorvastatin decreases blood lipids but is associated with side effects. Zhibitai is a traditional Chinese medicine used to treat blood lipid disorders. The objective of this study is to evaluate the lipid-lowering effect, antiinflammatory effect, and adverse events of zhibitai combined to atorvastatin in patients with coronary heart diseases (CHDs). METHODS Patients with CHD (n = 150) were randomized to: zhibitai 480 mg + atorvastatin 10 mg (ZA10 group), atorvastatin 20 mg (A20 group), and atorvastatin 40 mg (A40 group). Lipid profile, cardiotrophin-1 (CT-1), and C-reactive protein (CRP) were measured after 4 and 8 weeks of treatment. Self-reported side effects, liver function, kidney function, and creatine kinase levels were monitored. RESULTS After 8 weeks, triglycerides, total cholesterol (TC), LDL-cholesterol (LDL-C), and apolipoprotein B100 (ApoB100) levels were decreased in the ZA10 group (-64%, -37%, -46%, and -54%, respectively, compared with baseline), and these changes were similar to those of the A40 group (P > 0.05). CT-1 and high sensitivity-C reactive protein (hs-CRP) levels were significantly decreased in the ZA10 group after 4 and 8 weeks (4 weeks: -73% and 96%; 8 weeks: -89% and -98%; all P < 0.01), without differences among the 3 groups (P > 0.05). After 8 weeks of treatment, adverse events (abdominal distention, nausea, vomiting, and hunger) were found in 4, 5, and 7 patients in the ZA10, A20, and A40 groups, respectively. CONCLUSION ZA10 significantly reduced triglycerides, TC, LDL-C, ApoB, CT-1, and hs-CRP levels in patients with CHD, similar to the effects of A40 and A20, but ZA10 lead to fewer adverse events.

Abstract
Vitamin D receptor (VDR) polymorphisms were indicated to be associated with coronary artery disease (CAD); however, published studies reported inconsistent results.The aim of this meta-analysis is to reach a more accurate estimation of the relationship between VDR genetic polymorphisms and CAD risk.Eligible studies were retrieved by searching PubMed, Embase, VIP, Wanfang and China National Knowledge Infrastructure databases. Included and excluded criteria were formulated. The case group was patients with CAD, and the control group was healthy subjects. Summary odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate VDR polymorphisms associations with CAD risk. Heterogeneity was evaluated by Q statistic and I statistic.Seven studies of a total of 2306 CAD patients and 4151 control subjects met the inclusion criteria. The pooled results from Taq1 showed increased risk in allelic model (OR = 1.14, 95% CI = 1.02-1.28), dominant model (OR = 1.21, 95% CI = 1.02-1.43), heterozygote model (OR = 1.19, 95% CI = 1.00-1.1.42), and homozygote model (OR = 1.27, 95% CI = 1.01-1.61). Besides, Fok1 T > C showed decreased risk in allelic model (OR = 0.81, 95% CI = 0.65-1.00) and Fok1 A > G also showed decreased risk in allelic model (OR = 0.67, 95% CI = 0.45-1.00) and recessive model (OR = 0.55, 95% CI = 0.31-0.97). In Caucasian subgroup, Bsm1showed increased risk in allelic model (OR = 1.23, 95% CI = 1.02-1.47), heterozygote model (OR = 1.20, 95% CI = 1.00-1.44), and homozygote model (OR = 1.22, 95% CI = 1.02-1.45). In CAD patients with type 2 diabetes mellitus (T2DM), Apa1showed a decreased risk in heterozygote model (OR = 0.80, 95% CI = 0.66-0.98); however, increased risk in recessive model (OR = 5.00, 95% CI = 2.74-9.13) was discovered in CAD patients without T2DM.The Fok1 polymorphism may play a protective role in CAD, and the possible protective role in Apa1 CA genotype in CAD patients with T2DM needs further studies. The Taq1 polymorphism is found to be associated with a significant increase in CAD risk based on our analysis; moreover, increased risk in Apa1 polymorphism in CAD patients without T2DM and Bsm1 polymorphism in Caucasian group is also detected.
