ABSTRACT
Objective: To explore the relationship between ABO blood group and acute non-ST-segment elevation myocardial infarction (NSTEMI) occurrence. Methods: Our research included 2 groups: NSTEMI group, 1039 relevant patients treated in Anzhen hospital from 2013-01 to 2014-12 were retrospectively enrolled; Control group, 1039 subjects with normal coronary artery which was confirmed by coronary angiography. The Baseline condition including age, previous disease history and ABO blood group was studied. Logistic regression model was used to conduct single and multivariate analysis. Results: In NSTEMI group and Control group, blood type A was 287/1039 (27.6％) vs 259 (24.9％), type B was 345 (33.3％) vs 356 (34.3％), type AB was 102 (9.8％) vs 114 (11.0％) and type O was 305 (29.4％) vs 310 (29.8％), ABO blood group distribution for A and non-A, B and non-B, AB and non-AB blood group, O and non-O had no statistic meaning between 2 groups, P>0.05. Logistic regression analysis indicated that with adjusted risk factors of MI such as age, gender, hypertension, diabetes, hyperlipemia, cerebrovascular disease and smoking, the patients with blood types A, B and AB had the similar risk for NSTEMI occurrence than type O patients; there was no relationship between ABO blood group and NSTEMI occurrence. Conclusion: ABO blood group had no relationship to NSTEMI occurrence.

ABSTRACT
OBJECTIVE: To investigate the drug resistance of imipenem-resistant (IR) Gram-negative bacilli (GNB) in coal workers' pneumoconiosis (CWP)-chronic obstructive pulmonary disease (COPD) patients with lower respiratory tract infection (LRTI) and to provide a basis for clinical treatment. METHODS: Sixty-six strains of IR-GNB were isolated from the sputum of CWP-COPD patients with LRTI, and the bacterial spectrum was investigated. The drug resistance of bacterial strains was studied by KB disk diffusion method. RESULTS: Among the 66 strains of IR-GNB, 29 (43.9%) were Pseudomonas aeruginosa, 17 (25.8%) were Acinetobacter baumannii, and 11 (16.7%) were Stenotrophomonas maltophilia. The drug sensitivity test showed that all bacteria had high drug resistance; Pseudomonas aeruginosa had a susceptibility rate higher than 50% to ciprofloxacin, polymyxin B, fosfomycin, and amikacin, Acinetobacter baumannii had a susceptibility rate higher than 55% to fosfomycin, polymyxin B, and cefoperazone/sulbactam, Stenotrophomonas maltophilia had a susceptibility rate higher than 50% to cotrimoxazole, ciprofloxacin, piperacillin/tazobactam, levofloxacin, polymyxin B, and cefoperazone/sulbactam, and Pseudomonas cepacia had a susceptibility rate higher than 50% to piperacillin/tazobactam, ciprofloxacin, cefoperazone/sulbactam, and polymyxin B. CONCLUSION: The main species of IR-GNB are such non-fermentative bacteria as Pseudomonas aeruginosa, Acinetobacter baumannii, and Stenotrophomonas maltophilia in CWP-COPD patients with LRTI. These bacteria have high drug resistance and are sensitive to only a limited range of antibiotics.
