Objective To study the homology and clinical characteristics of healthcare-associated infection(HAI) due to Pseudomonas aeruginosa (P.aeruginosa)in medical intensive care unit (MICU),so as to guide the clinical prevention of P.aeruginosa transmission and improve therapeutic effect.Methods 55 P.aeruginosa strains isola-ted from 25 patients with HAI in the MICU of a hospital in January-December 2014 were performed pulsed-field gel electrophoresis (PFGE)homology analysis and clustering analysis,clinical characteristics,antimicrobial resistance, and transmission characteristics were analyzed.Results A total of 25 patients were investigated,with an average age of (69.62±2.13)years,mean hospital stay (49.34±3.18)days;prior to the isolation of P.aeruginosa, 84.00% of patients were treated with broad-spectrum antimicrobial agents for >2 weeks,76.00% of patients had been admitted to MICU,and 52.00% had a ventilator-assisted ventilation.55 strains of P.aeruginosa were mainly A,F,H,K,N,V,and W,which were the main epidemic strains;patients infected with A,F,H and K strains all had cross in their hospital stay;PFGE profiles of isolates from 4 patients during different periods showed different strain patterns;resistance rates of P.aeruginosa to ceftazidime (72.73%), piperacillin/tazobactam (70.91%),and imipenem(70.91%)were all high,resistance rate to amikacin was the lowest(25.45%).Conclusion Management of antimicrobial agents should be strengthened in medical institutions,HAI control meas-ures should be strengthened,so as to prevent the transmission of multidrug-resistant and extensively drug-resistant bacteria in hospitals.

Objective To evaluate the effect of the integrated strategy in prevention and control of intestinal nematodiasis in Hongze County,so as to provide the evidence for formulating the control strategies and measures in the future. Methods Since 1995,the integrated strategy has been carried out for intestinal nematodiasis,and the measures included deworming,health ed?ucation,safe water,sanitation and environmental remediation. The effects of the integrated strategy were evaluated by the inves?tigations of the prevalence of soil?transmitted nematodiasis,awareness of health knowledge and behaviors of residents. Results From 1995 to 2014,601 900 person?times were administrated with deworming medication and the coverage rate of villages and towns was 100%. The benefit rate of safe water was 100%. The popularity rate of harmless toilets was 92.77%. The prevalence of intestinal nematodiasis decreased from 26.04%in 1995 to 0.56%in 2014,and the difference had statistical significance(χ2=693.54,P < 0.01). The awareness rate of health knowledge and correct rate of health behaviors increased from 43.13% and 40.94%in 1995 to 98.00%and 96.80%in 2012,respectively(χ2=181.97 and 182.14 respectively,P<0.01). Conclusion The prevalence of intestinal nematodiasis has been controlled effectively through the integrated strategy in Hongze County ,Jiang?su Province.

Objective Investigate the operative techniques and early results of a normal thermic and non-cardiopulmonary bypass fashion to perform total thoracoabdominal aortic aneurysm repair (tTAAAR).Methods Between February 2009 and December 2010,41 patients with extensive Crawford Ⅱ thoracoabdominal aortic aneurysm (TAAA) underwent tTAAAR in our hospital.Among them,27 patients underwent tTAAAR in a normal thermic and non-cardiopulmonary bypass fashion.The mean age of this group of patients is (41.85 ± 10.11 ) years ( range 23-61 years),including 18 male and 9 female.The operation was performed via a combined left thoracoabdominal incision.The intercostal incision was through the left fifth (or sixth) intercostal space and an amputated costal arch.The abdominal incision was from the left linea pararectalis to the level of the pubic symphysis via a retroperitoneal approach.The diaphragm was incised circularly to expose the aorta.After the iliac arteries and proximal descending aorta were dissected and exposed sufficiently,two 10 mm side branches were anastomosed to iliac arteries in an end to side fashion.When this was accomplished,the proximal end of the main graft was anastomosed to the proximal descending aorta in an end to end fashion.Then the bypass from descending aorta to bilateral iliac arteries was established under normal thermia.The reestablishment of intercostal arteries and visceral arteries was followed with subsection circulatory arrest.Results The procedure was succeeded in all 27 patients but 1 patient died during operation because of pulmonary hemorrhage.The mean descending aortic circulatory arrest time was ( 13.78 ± 3.77 ) min,the spinal cord ischemia time was ( 19.19 ± 3.93 ) min,and the visceral organs ischemia time was ( 25.19 ± 5.88 ) min,respectively.Mean intubation time is (24.62 ±21.70) hours.Mean ICU stay time is ( 1.84 ± 1.29) days.Two of the 26 survivors suffered permanent spinal cord injury.The morbidity of pulmonary complication,temporal cerebral complications,renal failure,reoperation for hemorrhage,and delayed healing of incision was 11.54％,3.85％,3.85％,3.85％,7.69％,respectively.One Marfan patient suffered Stanford type A aortic dissection after 9 days of tTAAAR.She was rescued by emergency operation.Mean follow-up time was ( 16.04 ± 5.62 ) months,with a follow-up rate of 100％.No late death was found.Conclusion The normal thermic and noncardiopulmonary bypass tTAAAR is a reliable and effective therapeutic strategy for these patients.But the indication of this procedure is limited.If the thoracoabdominal aortic aneurysm grows too huge,the normal thermic tTAAAR cant be performed.So the TAAA patients in China should be treated in their early stage.

correlation with cross-sectional area and negative correlation with bucking ratio. The effect of fat mass on hip geometric parameters at the three regions was inconsistent. (3) Fat mass and percentage of body fat ( Fat%) showed negative correlation with cross-sectional area and average cortical thickness and positive correlation with bucking ratio in young group. However, the negative contribution produced by fat mass and Fat% to hip geometric structure became weaker gradually in middle-aged and older groups. ( 4 ) Limb lean mass yielded the largest positive contribution to cross-sectional area and average cortical thickness at all three regions in young group. However, the contribution produced by trunk lean mass became the largest positive contribution to cross-sectional area and average cortical thickness in older group. Conclusions Among all the body composition parameters, hip BMD has showed the most marked correlation with hip geometric structure. Lean mass is ranked the second in the correlation. The impacts of fat mass and lean mass on hip geometry are changing with aging and their different tissue distributions.
