Objective To explore the expression status of carbonic anhydrase Ⅲ (CA Ⅲ) from quadriceps femoris muscle in two kinds of muscle clinical phenotype (skeletal muscle atrophy group and skeletal muscles non-atrophy group) of chronic obstructive pulmonary disease (COPD).Methods Totally 37 inpatients from our hospital,were divided into 11 patients without COPD and 26 patients with COPD,in addition,according to body mass index,fat free mass index and quadriceps cross-section diameter,patients with COPD were divided into 14 skeletal muscles non-atrophy patients (SMNA)and 12 skeletal muscle atrophy patients (SMA).CA Ⅲ concentration of femoris quadriceps specimens was quantitatively determined using Western blot methods,CA Ⅲ mRNA expression levels of femoris quadriceps specimens were also quantitatively measured using RT-PCR,then compared among the 3 groups.Results There was significant difference in CA Ⅲ quantitative concentration and CA Ⅲ mRNA expression level in each group (P ＜ 0.05),further more,CA Ⅲ concentration expression level was significantly higher (P ＜ 0.01)in SMA group (1.260 ± 0.068) than in SMNA group (1.110 ± 0.014),the latter was significantly higher (P ＜ 0.01) than in the control group (1.000 ± O.062).CA Ⅲ mRNA expression level was significantly higher(P ＜ 0.01) in SMNA group(2.170 ±0.412) than in the control group(1.000 ±0.115),and was significantly lower than in SMA group (3.770 ± 0.788 ; P ＜ O.01).CA Ⅲ concentration and CA Ⅲ mRNA expression level increased at equal pace in SMNA group and SMA group,however,CA Ⅲ quantitative concentration and CA Ⅲ mRNA expression level were inconsistent in the two groups.Conclusion The expression status of CA Ⅲ in quadriceps femoris muscle was different in two kinds of muscle clinical phenotype of COPD.

Background and purpose:Advanced pancreatic cancer is characteristic of poor treatment eff icacy and short survival time. Gemcitabine is considered as front-line therapy for advanced pancreatic cancer. Gemcitabine combinations have shown a favorable impact on survival. We compared gemcitabine-based combination cheme therapy and gemcitabine(GEM) alone in patients with advanced pancreatic cancer through Meta analysis in phase Ⅲ clinical trials. Methods:MEDLINE and EMBASE searches were supplemented by information from trial registers of phase Ⅲ randomized controlled trials(RCTs) for GEM-based combination therapy and GEM alone for advanced pancreatic cancer. A quantitative meta-analysis was carried out by two reviewers based on the inclusion criteria from all available RCTs. The Meta-analysis involved 6-months and 1-year survival rate and objective remission rate(ORR) . Results:The Meta-analysis included 20 RCTs. The result of our Meta-analysis showed that there was signifi cant improvement in the GEM combination group with regard to the 1-year survival rate(RR:0.87,95%:(0.78,0.96) ,P=0.008) . The other result of our meta-analysis showed no signifi cant difference between two groups. Conclusion:GEM-based combination therapy may be effective with regard to the survival rate compared with GEM alone.

Objective To observe the efficacy of inhaled tiotropium bromide combined with budesonide/formoterol on reducing the frequency of acute episodes of symptom exacerbation and improving lung function,health status in chronic obstructive pulmonary disease (COPD). Methods Eighty-six patients with COPD were divided into 3 groups, combination group[29 cases, inhaled budesonide/formoterol (160 μg/4.5 μg, twice one day ) and tiotropium bromide ( 18 μg, once one day)], budesonide/formoterol group( 29 cases, 160 μg/4.5 μg, twice one day) and tiotropium bromide group(28 cases, 18 μg, once one day). The treatment continued for 3 months. Results Lung function, symptoms and health status improved obviously in three groups. The forced expiratory volume in one second (FEV1) of combination group after treatment was (1.24±0.18) L , which was improved by 11.7% compared with before treatment. It was significantly higher than that in budesenide/formoterol group and fiotropium bromide group (P < 0.01 ). The rescue medication consumptions and the times of acute episode of combination group were significantly decreased compared with those in the other groups,and there was significant difference (P <0.01). The SGRQ score of combination group was (35.6±13.9) points which was significantly lower than that of budesonide/formoterol group and tiotropium bromide group,and there was significant difference (P < 0.01 ).There was no statistical difference in the adverse events occurred in three groups (P > 0.05 ). Conclusions Combination treatment produces better control of symptoms and lung function and has no greater risk of sideeffects, compared with the treatment of budesonide/formoterol alone and tiotropium bromide alone. The combination treatment should be considered for patients with COPD.

Objective To investigate the correlation between the mierosatellite polymorphism of heme oxygenase-1(HOX-1)gene promoter and susceptibility to chronic obstructive pulmonary disease(COPD)in Han nationality of Southwest China and CT imaging.Method The alleles frequencies with varying number of(GT)n repeatings in the Hox-1 gene in 180 smokers with COPD and in 150 healthy smokers were analyzed.Results Polymorphisms of the(GT)n repeats were grouped into three classes:S(≤25 repeats),M(26-31 repeats),L(≥32repeats).The proportion of genotypic frequencies in the group with class L alleles(L/S,L/M,I/L)was significantly higher in the smokers with COPD than in healthy smokers(29.4%vs18.7%,P=0.023,OR=1.8,95%CI 1.1-3.1).However,there was no relationship between the polymorphism of HOX-1 gene and subtypes of COPD by CT imaging in COPD patients(P＞0.05).Conclusion Genetic polymorphism in Hox-1 is associated with development of COPD in Han nationality of Southwest China.But the polymorphism of HOX-1 gene is not associated with subtypes of COPD by CT imaging.

Objective To investigate the distribution and constituent of drug‐resistant bacteria of lower respiratory tract in‐fection among different regions (outpatient department ,wards ,RICU) to provide the basis for the clinical reasonable application of antimicrobial agents .Methods The K‐B disc diffusion method and the instrument method (VITEK‐TWO) were adopted and the detection results were interpreted according to the standards of CLSI 2010 .The detection data of 480 drug‐resistant strains isolated from the sputum ,branchoalveolar lavage fluid samples submitted in 3 regions of respiratory outpatients department by bacterial cul‐ture identification and drug susceptibility test were analyzed by using the WHONET5 .6 statistical software .Results The distribu‐tion and constituent of drug‐resistant bacteria of lower respiratory tract infection had obvious difference among 3 different regions . The top 4 of drug resistant bacteria were dominated by Gram‐negative bacteria .The drug resistance rate of Klebsiella pneumoniae in RICU was higher than that in the respiratory outpatients department and wards(P<0 .05) ,the resistance rate in the respiratory outpatients department ,wards and RICU to commonly used antibacterial drugs was similar;the multiple drug resistance of ESBLs‐producing strains was obviously higher than that of non‐ESBLs‐producing strains (P<0 .05) .Pseudomonas aeruginosa maintained the higher antibacterial activity to quinolone ,aminoglucosides ,cefepime ,imipenem ,cefoperazone/sulbactam ,and piperacillin/tazobactam ,but the resistance rate in RICU was significantly higher that in the respiratory outpatient department and wards (P<0 .05);the drug resistance of Acinetobacter baumanii in the respiratory wards and RICU was higher than that in the respiratory out‐patient department ,the resistances to imipenem were 64 .6% and 70 .4% respectively .The resistance of MRSA to rifampin in RICU was higher than that in the respiratory outpatient department and wards(P<0 .05) .Conclusion The distribution constituent and drug‐resistance rates have obvious differences among the respiratory outpatient department ,wards and RICU .Except being familiar with the drug resitant bacterial distribution and drug resistance rate monitoring situation ,clinical doctors should grasp the drug re‐sistance situation of drug resistant bacteria among different areas in various departments of own unit in order to rationally and effec‐tively use antibacterial drugs .

Objective To evaluate the clinical efficacy of the local drug resistance spectrum antibiotics and foreign guideline in the treatment of patients with community acquired pneumonia(CAP). Methods A prospective,randomized,single blind,and positive drug parallel controlled design was used in the treatment. CAP patients with no underlying disease outpatients and inpatients<48 hours were selected as the research object. The patients in the trial group were given sensitive local drug resistance spectrum antibiotics: moxifloxacin,400 mg and 1 times a day. The patients in the control group were given azithromycin tablets(each 500 mg,once daily) promulgated by the 2007 version of the IDSA / ATS adult CAP guideline. Results There were 106 cases of CAP patients,of which 77 cases completed treatment,including 39 cases in the experimental group and 38 cases in the control group. There were significant differences in the clinical efficacy and bacterial clearance rate between the two groups,with the clinical efficacy of 89.7% and 68.4%(P < 0.01),the bacterial clearance rate of 87.9% and 54.5%(P < 0.05),respectively. Conclusion The clinical efficacy of drug resistant spectrum sensitive antibiotics in the treatment of CAP in Kunming was better than that of IDSA/ATS. Clinicians should pay attention to the characteristics and composition of resistance of common pathogenic bacteria in our country during the study and reference from foreign guideline,and adjust the therapeutic regimen according to the changes of the local drug resistance monitoring data rather than copy the recommended treatment plan by foreign countries.
