OBJECTIVE:To systematically review the efficacy and safety of pituitrin combined with phentolamine versus pitui-trin alone in the treatment of bronchiectasis hemoptysis(BH),and provide evidence-based reference for the clinical treatment. METHODS:Retrieved from PubMed,Cochrane Library,EMBase,CJFD,Wanfang and VIP database,the randomized controlled trails(RCT)about pituitrin combined with phentolamine(test group)versus pituitrin alone(control group)in the treatment of BH were collected,and afterdata extract and quality evaluation ,Meta-analysis was performed by using Rev Man 5.2.3 statistics soft-ware. RESULTS:A total of 43 RCTs were included,involving 3 094 patients. Results of Meta-analysis showed the significant effi-cacy [RR=1.50,95%CI(1.38,1.62),P<0.001] and effective rate [RR=1.25,95%CI(1.20,1.30),P<0.001] in test group were sig-nificantly higher than control group,inefficacy [RR=0.29,95%CI(0.23,0.36),P<0.001], hemoptysis stopped or remission time [MD=-2.00,95%CI(-2.43,-1.57),P<0.001],incidence of headache [RR=0.36,95%CI(0.22,0.59),P<0.001],incidence of chest tightness [RR=0.41,95%CI(0.26,0.63),P<0.001],incidence of abdominal pain [RR=0.26,95%CI(0.16,0.43),P<0.001] and incidence of elevated blood pressure [RR=0.28,95%CI(0.14,0.56),P<0.001] in test group were significantly lower than control group,there were significant differences in 2 groups. CONCLUSIONS:Pituitrin combined with phentolamine has better efficacy and safety than pituitrin alone in the treatment of BH. Due to the limit of methodological quality and sample size,it re-mains to be further verified with more rigorously designed and long-term follow-up of large-scale RCT.

Objective To explore the safety of fat reduction treated by non invasive focused ultrasound.Methods A randomized double-blind and negative control clinical trial was carried out on the excess fat of 40 subjects' abdomen by a JCS-01 non-invasive focused ultrasound device.Subjects received treatments with the device on day 1 and day 7.Observations on the area treated and inquiries on feelings were conducted during treatments.Before the first treatment and 14 days after the treatment,laboratory examinations were performed,including liver function,blood lipid tests,etc.Results 40 subjects participated in the trial and 36 subjects (18 each in both treatment and control groups) accomplished 2 times of treatments,all followed-up and laboratory examinations.During the process of treatments,4 subjects in the experimental group complained about feelings of tepidity or pricking.One subject on blood test of triglyceride showed slightly higher than her early normal result,which fell to the normal level at reexamination.Conclusions Subjects treated by non-invasive focused ultrasound at the area of no more than 500 cm2 every time and at an interval of 6 days manifest little changes on the blood test results,with slightly local reactions but no complaints during follow-up.

Objective To investigate the possible association between two single nucleotide polymorphisms (SNPs) loci of apolipoprotein E (ApoE) gene and epileptic drug resistance in a central Chinese Han population.Methods A case control study was performed in 364 epileptic patients.According to the criteria of drug resistant epilepsy proposed by International League Against Epilepsy in 2010,143 patients were classified into drug resistant group and 221 patients into drug responsive group.The peripheral venous blood of each patient was collected for DNA extraction after clinical evaluation.The candidate ApoE SNPs loci,including rs7412 and rs769450,were genotyped by BeadChip Scanning and GoldenGate Assay following the Illumina protocols.The differences in allelic and genotypic frequency were compared between groups.Linkage disequilibrium was calculated through SHEsis platform.Results There was no significant difference for genotype or allele of rs7412 between groups.The GG genotype (OR =2.038,95％ CI 1.196-3.475,P=0.009) and G allele (OR =1.618,95％CI 1.193-2.193,P=0.002) of rs7412 were significantly more abundant in the drug resistant group.As for idiopathic epileptic patients,the GG genotype (OR =2.110,95％ CI 1.189-3.744,P =0.011) and G allele (OR =1.641,95％ CI 1.187-2.270,P =0.003) of rs7412 were still significantly more abundant in the drug resistant group.There was no linkage disequilibrium between the two loci with D' value of 0.072.Conclusion The GG genotype and G allele of ApoE rs769450 may be associated with epileptic drug resistance in a central Chinese Han population.

WHONET 5 .6 was applied for data analysis according to the breakpoints of Clinical and Laboratory Standards Institute 2013 . Results A total of 3 880 nonduplicate strains were collected in 2013 ,35 .2% (1 366/3 880) of which were gram positive organisms ,64 .8% (2 514/3 880) were gram negative bacteria .The top 6 most frequently isolated microorganisms were E . coli (20 .2% ) , K . pneumoniae (12 .0% ) , P . aeruginosa (11 .1% ) , coagulase negative Staphylococcus (9 .8% ) , A . baumannii (9 .8% ) ,E .f aecalis (8 .1% ) .The bacteria were mainly isolated from respiratory tract (51 .0% ) ,urine (26 .2% ) , and blood (9 .4% ) .The prevalence of both meticillin‐resistant Staphylococcus was higher than 72 .0% .No staphylococcal strainwasfoundresistanttolinezolid,vancomycinortigecycline.Amongthe509Enterococcusisolates,E.faecalisandE. f aecium accounted for 61 .5% and 32 .8% ,respectively .No enterococcal strain was resistant to vancomycin or tigecycline . Enterococcal isolates also showed low resistance (<2 .0% ) to teicoplanin and linezolid .About 67 .4% of the E .coli strains and 32 .0% of the K lebsiella isolates produced extended spectrumbeta‐lactamases.Thestrainsof E.coli,Klebsiella spp.,Enterobacterspp.,and Proteusspp.wererelatively susceptible to beta‐lactam/beta‐lactamase inhibitor combinations such as cefoperazone‐sulbactam and piperacillin‐tazobactam , carbapenems such as meropenem ,imipenem and ertapenem ,and amikacin (< 15 .0% of the strains were resistant) . K . pneumoniae isolates were more resistant than other gram‐negative bacilli .P .aeruginosa was relatively susceptible to amikacin , tobramycin ,cefepime ,gentamicin ,piperacillin‐tazobactam ,but more than 20% of these strains were resistant to meropenem and imipenem .More than 35 .0% of the A . baumannii isolates were resistant to any of the antimicrobial agents tested . Conclusions Antimicrobial resistance is still a serious threat in clinical antimicrobial therapy .It is important to promote the rational use of antimicrobial agents so that resistance is minimized . It is necessary to conduct epidemiological survey and proactively implement effective interventions in the clinical setting with relatively heavy burden of antimicrobial resistance .

Bacterial biodiversities of microbial mat and sediments, which were sampled from thermal springs of Tengchong Rehai in Yunnan, were preliminarily studied with PCR-denaturing gradient gel electrophoresis (PCR-DGGE). Directly extracted total DNA from environmental samples amplified by PCR with two sets of bacteria-specific primers. The PCR products, which include the V 8 and V 9 high-variable regions respectively, were analyzed by using DGGE. The DGGE profiles not only indicated the existence of higher levels of bacterial diversity, but also showed that the microbial mat and sediments have different dominant bacteria. Furthermore, the bacterial PCR-DGGE displayed clear profiles of bacterial structure selected by the key abiotic factors of the extreme environments, such as temperature and concentration of oxygen.
