ABSTRACT
Objective To investigate healthcare-associated infection(HAI)in patients in a cancer hospital,provide reference for controlling HAI in cancer patients,and guide rational use of antimicrobial agents.Methods Clinical data of patients in a cancer hospital between August 2006 and July 2012 were analyzed retrospectively.Results The incidence of HAI case was 1 .53% (2 060/134 389),and annual incidence showed a downward trend.The main in-fection site was lower respiratory tract (46.46%,n=957),followed by bloodstream (15.63%,n=322),abdominal and pelvic (14.03%,n=289).The main pathogens were Pseudomonas aeruginosa (16.16%,n=350),Staphylo-coccus aureus (9.97%,n=216),Klebsiella pneumoniae (9.79%,n=212),Escherichia coli (9.65%,n=209), and Candida albicans (6.51 %,n=141 ).Gram-negative bacilli,including Klebsiella pneumoniae and Escherichia coli ,were sensitive to carbapenems and β-lactamase inhibitors.Conclusion Lower respiratory tract is the major HAI site in patients with cancer,and gram-negative bacteria are the main pathogens.Carbapenems andβ-lactamase inhibitors are recommended for the empirical treatment of HAI in cancer patients.
ABSTRACT
The position of academic library in cultivation of healthy undergraduate personality was defined accord-ing to the frequent violent events and problems in cultivation of healthy undergraduate personality , the role of hu-manistic education in cultivation of healthy undergraduate personality was pointed out, and certain measures were put forward for the cultivation of healthy undergraduate personality , including creation of humanistic environment , development of literature resources, establishment of humanistic lecture room, enforcement of reading guidance, and implementation of emotional education .
ABSTRACT
Objective To judge the effect of plasma exchange (PE) to the patients with severe hepatopath of nonage according to evaluating the change of the liver function of reserve with 13C-methacetin breath test. Methods There are two groups: the case group and the control group. Each group has 30 patients. The patients in the case group were treated by PE. All the patients received 13C-methacetin breath test at before or one week after treatment. MVmax40, CUM40 and CUM120 were present. At the same time, clinical symptoms, glutamate-pyruvate transaminase (ALT), total bilirubin (TBiL) and prethrombin active (PTA) were observed. Results MVmax40, CUM40, CUM120 and PTA were higher, ALT and TBiL were lower in the case group after treatment (t=4.679, 4.752, 5.048, 5.413, 6.208, 7.413, P=0.000,P<0.01). After a week, MVmax40, CUM40, CUM120 and PTA were higher, ALT and TBiL were lower in the case group than that in the control group (t=2.260, 2.247, 2.476, 4.017, 3.250, 3.658, P<0.05). The total effective rates in the case group and the control group were 83.3 % (25/30) and 43.3 % (13/30),which are significant different(χ2 10.335,P<0.01). Conclusion PE can im-prove the liver reservation functionin the severe hepatopath of nonage.
ABSTRACT
Objective To know the sanitary situation of urban river surge and a certain section of Zhujiang River and whether Guangzhou reach of Zhujiang River will be taken as a swimming region. Methods From July 1 to July 15,2007,the period of swim,the spring-tide water and ebb-tide water at urban river surge and a certain section were sampled and tested. 54 water sample at urban river surge and 40 at a certain section,the items included pH value,turbidity,dissolved oxygen,chemical oxygen demand, amino-nitrogen and heat-resistant coliform. Results The results indicated that pH value and chemical oxygen demand of the water at urban river surge and a certain section were eligible,but amino-nitrogen,dissolved oxygen and heat-resistant coliform were not eligible,the turbidity was high,the water quality did not meet the Hygienic Standard for Swimming Place (GB 9667-1996). The chemical oxygen demand in spring-tide water was lower than that in ebb-tide water(P
