Objective To investigate the clinical characteristics of multiple drug resistant Acinetobacter baumannii infection in respiratory elderly patients.Methods A total of 102 elderly patients infected with multidrug-resistant Acinetobacter baumannii were enrolled in our hospital from January 2014 to December 2015.At the same time,no multiple drug-resistant Acinetobacter baumannii infection elderly patients was selected as a control group.The gender,age,antimicrobial use,white blood cell count,mechanical ventilation time and other differences between the two groups of elderly patients were compared.Results There were significant differences in the days of hospitalization [(18.7±7.5) d vs.(10.0±2.7)d],the time of application of invasive ventilator[(24.6±10.3) d vs.(11.6±6.9)d] and the time of application of antimicrobial agents[(26.2±13.1) d vs.(8.0±2.6)d] (t=19.463、15.436、26.905,all P＜ 0.05).There was no significant difference in immunosuppressant use,white blood cell count,serum protein level and APACHEⅡ score (all P＞0.05).Conclusions Reasonable scientific application of antimicrobial agents,reducing invasive mechanical ventilation time and improving patient immunity can help to reduce the risk of respiratory infection in elderly patients with multiple drug resistance to Acinetobacter baumannii.

Objective To probe the Th cytokine pattern in pemphigus,so as to clarify the pathogenesis of pemphigus and draw up new therapy.Methods Reverse transcription-polymerase chain reaction(RT-PCR)was used to examine the interferon gamma(IFN-?)and interleukin10(IL-10)mRNA expression on peripheral blood mononuclear cells(PBMCs)of20cases of pemphigus in acute stage,20cases in stable stage,and20normal controls.Results The IFN-?mRNA expression in20cases of pemphigus in acute stage was higher than that of controls(P

Objective:Colorectal cancer screening was performed on a general population with age ranging between 40 and 74 years old to evaluate the screening effects of questionnaire survey, fecal occult blood (FOB) test, and colonoscopy, as well as to provide some implications of colorectal cancer screening strategies. Methods: Two-step screening model of questionnaire survey combined with FOB test was applied for the screening. Colonoscopy was conducted in a high-risk population identified through preliminary screening as final diagnosis. Results:Based on the 2,117,304 cases screened, the screening compliance was 39.72%, and 126,118 cases (5.96%) were identified as high risk. Colonoscopies were performed on 25,837 cases, of which 8,095, 1,236, 134, 112, and 336 were identified as adenoma, advanced adenoma, severe dysplasia lesions, early cancer, and advanced cancer, respectively. The early stage di-agnostic rate was 81.52%. Conclusion:The colorectal cancer screening method performed in Tianjin can significantly concentrate on the high-risk population with colorectal cancer, increase the positivity rate of total colonoscopy, and economize medical resources.
