BACKGROUND:Sirolimus and Paclitaxel-eluting stents are commonly used for clinical application.Sirolimus-eluting stent have been proved safely and effectively to treat acute myocardial infarction.However,the comparison between those two eluting stents has been less reported yet.OBJECTIVE:To compare the security and long-term efficacy between Sirolimus- and Paclitaxel-eluting stents to the treatment of ST-segment acute myocardial infarction via percutaneous transluminal coronary intervention.METHODS:A total of 354 patients with ST-segment acute myocardial infarction,including 259 males and 95 females,were administrated with Sirolimus- and Paclitaxel-eluting stents.All cases were randomly divided into Sirolimus-elutin9 stent group (n=213) and Paclitaxel-eluting stent group (n=141).Major adverse cardiovascular events were compared between the two groups during 1-year following up.RESULTS AND CONCLUSION:One-year following up indicated that there was no significant difference in recurrent myocardial infarction (1.5% vs.1.5%) and cardiac death (2.5% vs.3.0%) between the two groups.Radiography showed that there was no significant difference in restenosis rate (5.0% vs.4.5%) between the two groups.Inner diameter lose was (0.19±0.34) mm in the Sirolimus-eluting stent group and (0.19±0.37) mm in the Paclitaxel-eluting stent group,and there was no significant difference.Additionally,there was also no significant difference in major adverse cardiovascular events between the two groups (8.9% vs.9.1%,P>0.05),suggesting that both Sirolimus-and Paclitaxel-eluting stents were safe and effective to the treatment of ST-segment acute myocardial infarction via percutaneous transluminal coronary intervention.

The binding characteristics of quinolone antibacterial agent, ofloxacin (OFLX) and ciprofloxacin(CPFX) with catalase(CAT) were studied by fluorescence spectroscopy in aqueous solution. It was showed that both OFLX and CPFX had a strong ability to quench the CAT intrinsic fluorescence through a static quenching procedure. The formation constant K and the number of bind ing site n were further calculated according to the fluorescence quenching r esults.

Objective To observe the distribution and drug resistance of pathogens cultured from the sputum of hospitalized patients with lower respiratory infection in acute exacerbation of chronic obstructive pulmonary disease (AECOPD) .Methods To i‐dentify the germiculture and test the drug susceptibility of the sputum or respiratory secretion isolated from the bronchial brush of 262 hospitalized AECOPD patients in People′s Hospital of Jiangxi Province from Janurary 2013 to December 2014 and analyze the results .Results Among all the AECOPD patients ,215 cases with positive sputum culture ,281 sputum pathogens were isolated . Gram‐negative bacilli were found in 190(67 .6% ) .Gram‐positive aureus were detected in 76(27 .1% ) .Fungus pathogens occurred in 15(5 .3% ) .The top six pathogenic bacteria were acinetobacter baumannii ,escherichia coli ,klebsiella pneumonia ,pseudomonas aeruginosa ,staphylococcus aureus ,streptococcus pneumonia .Drug susceptibility results showed that the drug resistance of acineto‐bacter baumannii was the strongest .Except that the drug resistance rate of cefoperazone/sulbactam and levofloxacin were less than 50 .0% ,the others were no less than 75 .0% .The drug resistance rate of escherichia coli and klebsiella pneumoniae to ampicillin , ampicillin sulbactam ,cefazolin ,ceftriaxone ,cefotetan ,gentamycin ,ofloxacin ,ciprofloxacin ,and compound sulfamethoxazole trime‐thoprim were no less than 70 .0% .The drug resistance rate of staphylococcus aureus to penicillin G ,oxacillin ,erythromycin ,clinda‐mycin were 100% .The drug resistance rate of streptococcus pneumoniae to erythromycin ,clindamycin ,tetracycline ,sulfamethox‐azole trimethoprim were greater than 75 .0% .Conclusion Gram‐negative bacilli are the main pathogenic bacterium in the AECOPD patients with lower respiratory infection .The key of treatment is to pay more attention to the bacterial culture and drug sensitive test ,use antibiotics reasonably according to the results of drug sensitive experiment .

To compare the efficiency of methods of DNA extraction from lungs of Pomacea canaliculataused in PCR assay, 80 P.canaliculata collected in field were divided into 8 groups and the lungs of each snail were separated from the soft body. Six methods of DNA extraction from lungs of P. canaliculata were used to extract DNA from lungs, i.e. With Qiagen, Tiangen,and Omega commercial DNA extraction kits, guanidine thiocyanate method, Chelex 100 resin method and Chelex-silica particle method. The 16S rDNA of C.canaliculata was amplified by PCR and the concentration of PCR-products relative to marker was determined in order to evaluate the efficiency of each method. It was demonstrated that each method was valid to extract DNA from lungs used in PCR assay, but the concentrations of PCR-products were different. The concentrations of PCR-products obtained by Qiangen kit, Omega kit, Chelex 100 resin method and Chelex-silica particle method were significantly higher than those of other 4 methods of DNA extraction, in which Qiangen and Omega kits were suitable for small sample size. In term of efficiency and cost, Chelex 100 method and Chelex-silica particle method were feasible for large sample scale, while the guanidine thiocyanate method was preferred due to its fast extraction and low cost, but on account of its toxicity, it is used in urgent status or in large scale of sample extraction.

Objective:To observe the therapeutic effect and toxicity of local Kanseran injection in combination with chemotherapy in advanced NSCLC patients.Methods:A total of 18 cases was recruited in this study. After desensitization,Kanseran injection was injected into tumor mass through fibrobronchoscope,2 mg every time,once per week. Meanwhile,MVP regimen was administered.Results:Of the 18 patients,1 was completely relieved,7 cases were partially relieved. The response rate was 44.4%. After treatment,when examined by fibrobronchoscope the tumor masses of 15 patients became smaller. The main side effects were fever,alopecia and gastrointestinal reaction,which were mild and tolerable.Conclusion:Local Kanseran injection into tumor mass in conjunction with chemotherapy is effective and safe in the treatment of advanced NSCLC patients with bronchus obstruction.

BackgroundHigh myopia is one of leading causes of blindness,so far the pathogenesis remains unclear.Two single-nucleotide polymorphisms (SNPs) of rs6885224 and rs12716080 in CTNND2 gene were recently found to be associated with high myopia in Singaporean Chinese.But whether these SNPs are related with the pathogenesis of high myopia in Han Chinese is worth studying,Objective This study was to investigate the relationship between the genetic variations of the CTNND2 gene and high myopia in Han Chinese.MethodsA case-controlled association study was designed.Nine hundred and thirty-three individuals with high myopia and 1227age- and gender-matched normal subjects were included in this study.The 5 ml of periphery blood was obtained from all subjects for the extraction of genomic DNA.The target DNA was amplified using PCR and purified by the SNaPshot method.Four SNPs rs12716080,rs917012,rs6885224 and rs16901340 in the CTNND2 gene were genotyped.This study was approved by the Ethic Committee of Sichuan Provincial People Hospital.Written informed consent was obtained from each subject before his/her enrollment.Results The frequencies of the genotypes rs6885224,rs12716080,rs917012,rs16901340 SNPs were in Hardy-Weinberg equilibrium (HWE) ( P=0.181,0.085,0.732,0.313,0.264,0.663,0.084,0.196).There were no significant differences in genotypes frequency distribution ( in turn P =0.654,0.406,0.828,0.403 ) and allele frequency distribution of the CTNND2 gene ( in turn P =0.377,0.209,0.743,0.198) between the high myopia group and normal control group.The haplotypes (TA and GA)frequencies of rs12716080 and rs917012 in the high myopia group were significantly different from those of the normal control group(TA:0.784 vs.0.719;GA:0.087 vs.0.136) (x2 =6.115,P=0.013 ;x2 =6.634,P=0.010),but those of GG were similar between the high myopia group and normal control group ( 0.123 vs.0.143,x2 =0.889,P =0.346). ConclusionsThe SNPs rs12716080,rs917012,rs6885224 and rs16901340 in CTNND2 gene were not responsible for high myopia,however,the haplotypes of rs12716080 and rs917012 are susceptible for high myopia in Han Chinese.
