ObjectTo observe the clinical efficacy and safety of the combination therapy of atorvastatin and JiangZhi Decoction (ZJD) for primary hyperlipidemia (Tan Zhuo Zu E Zheng) and to analyze the interactions of drugs in hypolipidemic effect. MethodsA 2*2 factorial design, single-blind, stratified randomized controlled trial according to the level of lipid was conducted. Primary hyperlipidemia (Tan Zhuo Zu E Zheng) patients met the inclusion criteria were divided into 5 groups:ATV 10 mg group (group A), ATV 20 mg group (group B), ATV 10 mg+JZD group (group C), ATV 20 mg+JZD group (group D), JZD group (group E). After two weeks treatment, the efficacy and safety among the 5 groups were compared. ResultsA total of 92 patients were included, of which, 20 were in group A, 25 in group B, 21 in group C, 17 in group D, and 9 in group E. The results showed that:(1) There was no significant difference between group C and group B in the reduction of serum total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) (PTC=0.226, PLDL-C=0.818). (2) The results of 2*2 factorial analysis showed that, there was no significant interaction between TCM factor and western medicine factor (PTC=0.605, PLDL-C=0.843). (3) There were no significant differences in safety outcomes among 5 groups (all P values >0.05). ConclusionATV 10 mg+JZD and ATV 20 mg have a similar efficacy in reducing TC and LDL-C. There is no obvious interaction between JZD and ATV in hypolipidemic effect, and the combination therapy of ATV and JZD is safe.
ObjectiveTo systematically review the effect and safety of continuous veno-venous hemofiltration (CVVH) on patients with hyperlipidemic pancreatitis. MethodsDatabases including the Cochrane Library (Issue 2, 2014), PubMed, EMbase, CBM, CNKI and WanFang Data were electronically searched for randomized controlled trials (RCTs) about CVVH on patients with hyperlipidemic pancreatitis till Feb. 12, 2014. According to the inclusion and exclusion criteria, literature was screened, data were extracted, and the methodological quality of included studies was also assessed. Then, meta-analysis was performed using RevMan 5.2 software. ResultsA total of 7 trials met eligibility criteria, involving 360 cases, including 183 cases of CVVH group and 177 cases of control group. The results of meta-analysis showed that compared with only routine medical treatment, CVVH significantly reduced the levels of lipid (WMD=-4.63, 95%CI-5.98 to-3.27, P < 0.000 01), levels of IL-6 (WMD=-29.59, 95%CI-34.30 to-24.89, P < 0.000 01), overall mortality (RR=0.39, 95%CI 0.18 to 0.84, P=0.02), and APACHE II score (WMD=-3.34, 95%CI-5.12 to-1.56, P=0.000 2) after treatment. ConclusionCVVH is more effective for hyperlipidemic pancreatitis than only routine medical treatment. Due to the limited quantity and quality of the included studies, further high-quality, multicenter, large-scale RCTs are required to verify the above conclusion.

Objective To compare two ways of establishing hyperlipidemia model in rats with fat emulsion.Methods Thirty male SD rats were randomly divided into three groups， which fed with normal diet （normal control group）， low concentration fat emulsion （low concentration fat emulsion group）， and high concentration fat emulsion （high concentration fat emulsion group）， respectively. All the rats were sacrificed and tested for serum total cholesterol （TC）， triglyceride （TG）， high density lipoprotein-cholesterol （HDL-C）， and low density lipoprotein-cholesterol （LDL-C）in two weeks after establishment. Results The levels of TC， TG， HDL-C， and LDL-C in the high concentration fat emulsion group were significantly higher than those in the normal control group and the low concentration fat emulsion group （P＜0.05）；the levels of TC， TG， and HDL-C in the low concentration fat emulsion group didn’t significantly differ from normal control group （P＞0.05）. Conclusions High concentration fat emulsion can be used to establish hyperlipidemia model in SD rats， low concentration fat emulsion is not suitable for establishing hyperlipidemia model in SD rats.
Objective To assess the efficacy and safety of Xuezhikang capsule (XZK) for hyperlipidemia. Methods MEDIINE，EMBASE, Cochrane Central Register of Controlled Trials(CCTR), Cochrane Metabolic and Endocrine Disorders Group data bank, and Chinese Biomedical Database(CBM), China Hospital Knowledge Database(CHKD) were searched，and the published/unpublished information was handsearched (updated to Dec., 2005) to identify randomized controlled trials (RCTs) or quasi-RCT of XZK versus statins or other lipid lowering drugs in treating hyperlipidemia patients. The quality evaluation, data extraction and analysis were conducted by the method recommended in Cochrane Reviewer’s Handbook 4.2.2. Data were analyzed using Review Manager (Version 4.2). Results Eleven trials (conducted in China) were identified, including 1 073 patients with hyperlipidemia met the inclusion criteria. All the included RCTs were graded as B or C. ① The effect of XZK in reducing TC: There were no significant differences between XZK and statins ( WMD 0.06, 95%CI-0.09 to 0.20 and RR1.02, 95%CI 0.93 to 1.12), XZK and fibrates (WMD 0.05, 95%CI -0.22 to 0.31) and XZK and probucol(WMD 0.42, 95%CI -0.01 to 0.85). XZK was superior to hexanicit (WMD 0.96, 95%CI 0.73 to 1.18). ② The effect of XZK in reducing TG: XZK had the same effect as statins (WMD 0.02, 95%CI -0.10 to 0.14 and RR 1.17, 95%CI 0.92 to 1.49) and hexanicit (WMD 0.28, 95%CI -0.17 to 0.73 ).Meanwhile, XZK was superior to probucol (WMD 0.71, 95%CI 0.22 to 1.20), but it was not as good as fibrates (WMD -0.81, 95%CI -1.40 to -0.23). ③ The effect of XZK in increasing HDL-C：XZK had the same effect as that of statins (WMD -0.03, 95%CI -0.10 to 0.04 and RR 1.03, 95% CI 0.80 to 1.33). The effect of XZK was better than that of hexanicit (WMD 0.15, 95%CI 0.01 to 0.29). XZK had the same effect of fibrates (WMD 0.03, 95%CI -0.08 to 0.15) and probucol (WMD 0.04, 95%CI -0.16 to 0.24). ④ The effect of XZK in reducing LDL-C：The effects of XZK and statins were the same (WMD -0.23, 95%CI -0.61 to 0.15 and RR 1.15, 95%CI 0.75 to 1.77). The effect of XZK was better than that of hexanicit (WMD 0.53, 95%CI 0.16 to 0.90). Meanwhile, XZK had the same effect as those of fibrates (WMD 0.19, 95%CI -0.12 to 0.50) and probucol (WMD 0.35, 95%CI -0.03 to 0.73). ⑤ The adverse reactions of XZK were mainly the gastrointestinal tract reaction, while liver function abnormality and myalgia were scarcely found. Conclusion Xuezhikang capsule have the same effects as those of statins in reducing the levels of TC, TG, LDL-C and raising HDL-C in patients with hyperlipidemia. No obvious adverse reactions are found during the short-term treatment. But further confirmation with clinical randomized controlled trials of high quality, large sample and long-term follow-up is needed.
ObjectiveTo investigate the expression and significance of CD73 in rats with intermittent hypoxia and high fat diet.MethodsThe rat model of chronic intermittent hypoxia combined with high fat diet was established. Twenty-four healthy male Wistar rats in the SPF level were randomly divided into 4 group, with 6 rats in each group, namely group A (normoxia and normal diet), group B (normoxia and high fat diet), group C (intermittent hypoxia and normal diet)and group D (intermittent hypoxia and high-fat diet). After 6 weeks of experiment, the serum lipid levels, myocardial morphological changes under microscope, the expression level of CD73 protein detected byimmunohistochemistry and Western blot in myocardial cells in rats were compared among these groups.ResultsThe serum lipid levels were significantly different among these groups (P<0.05). HE results showed that the myocardial cells of group A had no obvious abnormalities; disorganized visible myocardial fibers with focal necrosis in groups B and C; myocardial cell injury was most obvious in group D, in which visible muscle fibers arranged in disorder, and grain was not clear, part of the muscle fibers were dissolved predominantly. Compared with group A, CD73 protein expression levels in myocardial cells in groups B, C, and D were significantly elevated (P<0.01). Furthermore, CD73 protein expression level in myocardial cells in group D was significantly higher than those in groups B and C (P<0.01). Western blot showed consistent results as immunohistochemistry: compared with group A, CD73 protein expression levels in groups B, C, and D were significantly elevated (P<0.05), and CD73 protein expression level in myocardial cells in group D was significantly higher than those in groups B and C (P<0.01).ConclusionChronic intermittent hypoxia and high fat diet can cause myocardial cell damage and upregulate CD73 expression in the cardiomyocytes.
