Objective:To evaluate the efficacy and safety of rosuvastatin and atorvastatin in the treatment of the patients with primary hyperlipidemia in China.Methods:The related literatures in CNKI,VIP,Wanfang medicine network,PubMed/MEDLINE,CBM and Chinese dissertations full text database were retrievaled by computer from the establishment time of database to December 31,2015. Two researchers according to the inclusion and exclusion criteria independently selected the studies and extracted the data and assessed the quality of the literatures.The Revman 5.0 software was used to perform Meta analysis of all effect indicators in various groups.Results:A total of 7 randomized controlled trial (RCT)were included,and there was no significant abnormality in bias evaluation. 8 weeks after treatment, the total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C)and high density lipoprotein cholesterol (HDL-C)levels of the patients in 5 mg rosuvastain group and 10 mg atorvastatin group had no significant differences between before and after treatment (P >0.05);the HDL-C levels of the patients in 10 mg rosuvastatin group and 10 mg atorvastatin group had significant differences between before and after treatment (P < 0.05),but the TG,TC,and LDL-C levels had no significant differences (P >0.05);the TG,TC,LDL-C and HDL-C levels of the patients in 5 mg and 10 mg rosuvastatin groups had no significant differences between before and after treatment (P > 0.05).12 weeks after treatment,there were no significant differences in the TC and LDL-C levels between 10 mg rosuvastatin group and 10 mg atorvastatin group (P >0.05),but there were significant differences in the TG and HDL-C levels (P <0.01).The incidence of adverse reactions of the patients in three groups had no significant differences (P >0.05).Conclusion:5 mg rosuvastatin and 10 mg atorvastatin in the treatment of the patients with primary hypercholesterolemia have similar lipid-lowering effect;with the the increase of the treatment time and the dose,10 mg rosuvastatin can obviously reduce the TG level and increase the HDL-C level of the patients,and the incidence of adverse reactions of two kinds of doses of rosuvastatin has no obvious difference.

To evaluate the prevalence of mosquito-borne viruses in Manshi and Ruili (Yunnan Province, China), we collected 2 149 mosquitoes (17 species) in August 2010. Virus isolation was undertaken by the cul- ture of baby hamster kidney cells (BHK-21 cells). Two virus-like isolates were obtained: DHL10M117 was isolated from collected in Mangshi; DHL10M110 was obtained from Anopheles vagus collected in Rui- li. Both isolates caused cytopathic effects,illness and death in suckling mice inoculated with these isolates via the intracerebral route. Two positive amplicons, 702-bp from the S segment and 456-bp from the M segment,were obtained using reverse transcription-polymerase chain reaction using primers specific for the Akabane virus (AKV). Phylogenetic analysis suggested that these two virus stains had a distant relation- ship with AKVs from Kenya and Australia,but were genetically close to those from Japan,South Korea, and Taiwan. However,they were separate from other Asian strains and grouped into a small branch. The highest nucleotide and amino-acid sequence identity of the S segment was found with the CY-77 strain from Taiwan (96.6% and 99.6% for DHL10M117 and 96.7% and 100% for DHL10M110,respectively). Com- parison of the M segment showed they shared the highest amino acid identity with CY-77 (99.6% and 100%, respectively), whereas the highest nucleotide identity was found with the Iriki strain from Japan (99.6% and 100%, respectively). Compared with the MP496 strain from Kenya,they displayed lower lev- els of sequence homology, at 69.7% and 70.0% for nucleotide sequences of the two loci,and 91. 0% for a- mino acids. Our results identified that DHL10M117 and DHL10M110 were strains of AKV,and provided molecular biological evidence for the existence of AKV in Yunnan Province. These AKV strains that are circulating in Yunnan Province share a close genetic relationship with strains from the rest of Asia. Culex tritaeniorhynchus and Anopheles vagus may serve as transmission vectors.

Objective To investigate the expression of normal epithelial cell-specific-1(NES1) gene in normal gastric epithelial cells and different gastric cancer cell lines and the effects of 5-aza-2-de- oxycytidine(5-aza-dC)on the expression of NES1 gene.Methods Expression of NES1 mRNA in five gastric cancer cell lines(MKN-28,SGC-7901,AGS,MKN-45 and HGC-27)and normal human gastric epithelial cells were detected by real-time PCR.After treatment with 5-aza-dC,a DNA methyltransferase inhibitor,the expression of NES1 mRNA in gastric cancer cell lines was detected by real-time PCR. DNA methylation status of NES1 gene was assayed by methylation-specific PCR(MSP).Results The expression of NES1 mRNA was decreased in all gastric cancer cell lines.A strong correlation between ex on 3 hypermethylation and loss of NES1 mRNA expression in gastric cancer cell lines was noted.5-aza dC treatment of NES1-nonexpressing tumor cell lines resulted in a dose-dependent induction(SGC-7901, MKN-45,MKN-28 and AGS)and increase (HGC-27) of NES1mRNA expression in gastric cancer cells. Conclusions The study suggested that hypermethylation was a responsible factor for tumor-specific loss of NES1 gene expression in gastric cancer cells.Treatment of gastric cancer cell lines with a demethylating agent led to reexpression of NES1 suggesting an important role of hypermethylation in loss of NES1 gene expression.

Aim: To observe the changes in thymocyte and its microenvironment in aged mice after bilateral testicular resection.Methods: In male old mice, at the 25th day after testicular resection, the peripheral blood and thymus were collected. Blood and thymus suspension smears were prepared for quantitative histochemistry and immunohistochemistry study under light and electron microscopes. Results: In testes resected mice the size and the weight of thymus were markedly increased. The demarcation between cortex and medulla was clear. The cortex was thickened and the cell density was increased. The ratio of cortex/medulla stereometry was increased. The total cell count, thymocyte count,the percentage of acid α-naphthyl acetate esterase (ANAE) positive thymocytes, nonlymphocytes and the rosette formation of macrophages and thymocytes were all increased. The thymocytes surrounded closely to the light thymic epithelial cells, dendritic cells or macrophages. The lymphocytes, particularly the ANAE positive lymphocytes of peripheral blood were increased. Conclusion: After bilateral testicular resection, the thymus of aged male mice showed morphological regeneration and the thymocytes and its microenvironment appeared to be definitely improved. It is suggested that testicular resection may improve immune function.

Objective To evaluate the diagnostic accuracy of coronary artery stenosis caused by calcified coronary artery plaques with 64-detector row CT under different conditions. Methods Totally 165 patients with coronary artery calcification accompanied by one or more branches stenosis more than 50% detected with computed tomography coronary angiography (CTCA) were collected. The Agatston calcium score (ACS) and stenosis rate were calculated based on per-patient, per-vessel, per-segment, various stenosis degree and different morphology of calcification as the analysis object, respectively. The measurement results of coronary angiography (CAG) were taken as the gold standard. The diagnostic accuracy was evaluated with receiver operating characteristic (ROC) curves which were created to assess the diagnostic value and to determine the diagnostic cutoff level (threshold). Results When per-patient analyzed, the greatest diagnostic accuracy rate was obtained with ACS threshold of 113.5, and the area under curve (AUC) value of ROC was 0.791. With the analysis object of per-vessel, the greatest diagnostic accuracy rate was found in right coronary artery and its sub-branches, and the AUC value was 0.897. Per-segment analyzed, the highest accuracy rate was obtained in RCA1 segment, and the AUC value was 0.894. When the analysis object was the morphology of calcification, the range of AUC value was merely 0.601-0.667, while the diagnostic value was rather low. The highest accuracy of CTCA was obtained in stenosis less than 50%, and the AUC value was 0.856. Conclusion Coronary artery calcification has different influence on the diagnostic accuracy rate of coronary artery stenosis with CTCA in various situations. Moreover, the morphology of the calcification may not be the main impact factors of the diagnostic accuracy.

OBJECTIVEOver the last few decades, diabetic cardiomyopathy has been identified as a significant contributor in cardiac morbidity. However, the mechanisms of diabetic cardiomyopathy have not been clarified.

METHODSIn the present study, a diabetic rat model was induced by the intraperitoneal injection of streptozotocin. The myocardial CD147 expression and extent of glycosylation, as well as thematrixmetalloproteinases(MMPs) expression and activity, were observed in the diabetic and synchronous rats.

RESULTSThe results showed that CD147 located on sarcolemma of cardiomyocytes. The myocardial CD147 expression and glycosylation were significantly increased in the diabetic rats as compared with the control. Expression of MMP-2 protein, MMP-2 and MMP-9 activity were also increased in left ventricular myocardium in the diabetic rats. Tamoxifen only inhibited the enhanced expression of myocardial CD147 in the diabetic rats, but not in synchronous control rats. Tamoxifen inhibited glycosylation of myocardial CD147 in both diabetic and control rats. The inhibition of tamoxifen on CD147 glycosylation was stronger than on the expression in the myocardium. The extent of myocardial CD147glycosylation was positively related toMMP-2 and MMP-9 activity. Tamoxifen induced an inhibition of myocardial MMP-2 and MMP-9 activity in the control and diabetic rats.

CONCLUSIONThese results indicate that myocardial CD147 expression, especially the extent of glycosylation, regulates MMP-2 and MMP-9 activity, then accelerates cardiac pathological remodeling inducing diabetic cardiomyopathy. Tamoxifen inhibits myocardial CD147 glycosylation and further depress the activity of MMPs. Therefore, tamoxifen may protect the diabetic rats against diabetic myocardium.

A novel serine protease with high purity was extracted from the venom of Agkistrodon hlays Pallas using monoclonal antibody affinity chromatography. This protease releases bradykinin and has arginine esterase activity without being activated. After purification, its hydrolytic activity exceeded 800 U/mg, far higher than its counterparts from mammalian sources. The purity of the kininogenase could exceed 95%. The acute toxicity and the long-term toxicity of this kallikrein was studied for its potential clinical application. The maximum tolerance dose in adult was 150,000 times greater than the maximum applied dose, and long-term administration at the dose 50 times of allowed clinical dose did not obviously after the animals' body weight, survival condition, liver function, renal function, or blood routines, suggesting the extremely low toxicity of the kallidrein.

BACKGROUNDPhotodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) is an emerging technique for the treatment of genital human papillomavirus (HPV)-induced benign and premalignant lesions. We report here in a case series of condyloma acuminata (CA) in pregnancy successfully treated with ALA-PDT.

METHODSFive pregnant patients with CA received three to four times treatment respectively. Patients were followed up for 6 - 23 months after treatment.

RESULTSThe clearance rate of genital warts was 100%. No recurrence was found during the follow-up period. Major adverse events reported were mild erosion, pain, and local edema. All pregnancies resulted in healthy live births without delivery complications.

CONCLUSIONSPDT with topical ALA seems to be safe and effective in the treatment of CA in pregnancy. It demonstrated high clearance rate of warts, was well-tolerated by patients, and showed no adverse effects on mothers or fetuses. ALA-PDT may be an ideal strategy of treatment for pregnant women with CA.
