ABSTRACT
Objective To investigate the effectiveness and safety of rosuvastatin and simvastatin in the treatment of hyperlipidemia. Methods The database including CNKI, VIP, Wanfang data base and CBM were retrieved to search the clinical randomized controlled trials (RCT) of rosuvastatin and simvastatin in the treatment of hyperlipidemia, and the data were analyzed with Review Manager 5.2. Results Eighteen RCTs were included with a total sample size of 1819 cases with hyperlipidemia, in which there were 917 patients in rosuvastatin group and 902 in simvastatin group. The Meta-analysis results showed that there were significantly lower serum levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG) and significantly higher level of high-density lipoprotein cholesterol (HDL-C) in rosuvastatin group compared with those of simvastatin group [(MD=-0.15, 95%CI:-0.22--0.09, P<0.01), (MD=-0.18, 95%CI:-0.25--0.11, P<0.01), (MD=-0.23, 95%CI:-0.28--0.19, P<0.01) and (MD=-0.11, 95%CI:-0.06--0.15, P<0.01)]. There was no significant difference in the incidence of gastrointestinal adverse reaction between the two groups. Conclusion The current clinical evidences show that rosuvastatin has a better effect on the treatment of hyperlipidemia, and has no adverse reactions.
ABSTRACT
<p><b>OBJECTIVE</b>To analyze the effects of continuous cropping and soil treatment on rhizosphere fungal community of Panax quinquefolium, and the correlation between rhizosphere fungal community and growth of P. quinquefolium.</p><p><b>METHOD</b>Field plot trail of continuous cultivated P. quinquefolium was conducted, meanwhile continuous cropping soil was treated by organic carbon fertilizer plus methylene dithiocyanate and Kingbo respectively. The rate of seedling survival, root disease index and root weight were investigated. Dilution plating was used to analyze the rhizosphere fungal community, multiple comparisons including H, M(a) and J were performed between rhizosphere fungal community and growth of P. quinquefolium.</p><p><b>RESULT</b>As to P. quinquefolium planted in continuous soil, the rate of seedling survival, root weight decreased, root disease index increased remarkably (P<0.05). Meanwhile the fungal counts decreased 50% -63% , the diversity index (H') decreased 39%-43%, while the ratio of Penicillium and Aspergillus increased. There was a significant negative correlation between rhizosphere fungal diversity and P. quinquefolium root disease index (r = -0.970, P=0.006). Organic carbon fertilizer plus methylene dithiocyanate treatment could improve the rate of seedling survival and root weight, and could partly increase the rhizosphere fungal diversity.</p><p><b>CONCLUSION</b>In continuous cropping soil of P. quinquefolium, the rhizosphere fungal counts and diversity index decreased, meanwhile the fungal community composition changed. Organic carbon fertilizer plus methylene dithiocyanate treatment could improve the growth of continuous cultivated P. quinquefolium.</p>
