Objective To evaluate the incidence of surgical site infection (SSI)in patients with colorectal cancer and identify the risk factors of SSI.Methods A total of 392 patients who underwent colorectal cancer resection at the First Affiliated Hospital of Chongqing Medical University between September 2012 and September 2013 were included and analyzed in terms of the presence of SSI.SSI risk factors were identified by both univariate and multivariate analysis.Results The overall incidence of SSI was 23.0%.Univariate analysis showed that duration of operation above 75 th percentile,colostomy,surgical procedure, type of surgical incision,and American Society of Anesthesiologists (ASA)score were significantly associated with higher risk of SSI (P <0.05).Binary logistic regression suggested that duration of operation above 75 th percentile (P = 0.000,OR =3.017),colostomy (P =0.008,OR=2.642),Contaminated incision (P =0.016,OR=3.311)and laparoscopic surgery (P =0.016,OR=0.523)were significantly different in terms of presence or absence of SSI.Conclusions Duration of operation above 75th percentile,colostomy and contaminated incision are independent risk factors,while laparoscopic surgery is a protective factor for SSI in patients with colorectal cancer.

Objective To investigate the current state of nurse leaders′leadership and nurse physician cooperation, to explore the relationship between them, and to provide reference for improving nurse physician cooperation situation. Methods Totally 193 nurse leaders were recruited who were participated in Anhui nursing management training courses. A series of questionnaires were used to collect data, including general information, competency inventory for registered nurse, nurse physician cooperation scale. Results One hundred and eighty- two questionnaires were valid. The score of nurse managers′leadership was (27.85±6.27) points,while the score of nurse physician cooperation scale was (68.31±11.67) points. Hierarchical regression analysis showed that the control of general information, leadership for the interpretation of the nurse physician cooperation level increased by 27.3% (△R2 = 0.273, P = 0.000). Conclusions Hospital managers can adopt effective strategies to raise the level of nurses' leadership, which further increases the nurse physician cooperation level.

Background Penetrating keratoplasty (PKP) has become an effective method of treatment for fungal keratitis in recent years,but the application timing of glucocorticoids after PKP is still unclear.Literature reported that the concentration of tear (1,3)-β-D-glucan in fungal keratitis was significantly higher than that in normal.Objective This study was to investigate the change of tear (1,3)-β-D-glucan before and after PKP in fungal keratitis and to explore the application duration of anti-fungal drugs and application timing of glucocorticoids.Methods This study protocol was approved by ethic committee of Affiliated Hospital of Qingdao University.A serial cases-observational study was performed from August,2011 to December,2012.Twenty eyes of 20 patients with fungal keratitis were collected in Affiliated Hospital of Qingdao University.PKP was performed in affected eyes,and the fellow health eyes served as controls.Tear of 50 μl was obtained in the controls on 1 day before operation and 1 day,7,14,21 and 28 days after operation to detect tear (1,3)-β-D-glucan levels.Results Tear (1,3)-β-D-glucan levels were (14.67±3.84)mg/L,(1 861.66±196.17) mg/L,(927.71±155.82)mg/L,(392.30±71.22)mg/L,(179.60±40.47) mg/L,(40.20± 12.46) mg/L and (15.12± 1.80) mg/L in the control group,preoperative 1 day,postoperative 1 day,7,14,21,28 days,respectively,showing a significant difference among various time points (F=883.45,P=0.00).Tear (1,3)-β3-D-glucan levels were gradually reduced with the lapse of the postoperative time,with significant differences between adjacent timepoints (t' =13.84,t =16.67,t' =11.02,t' =13.97,t' =-8.45,all at P=0.00).Tear (1,3)-β-D-glucan levels in postoperative 28 days came near that of normal control group,without significant difference between them (P =0.64).Fungal keratitis recurred in 2 eyes on the fifth and sixth day after operation,with the tear (1,3)-β-D-glucan levels of 2 350.24 mg/L and 1 992.82 mg/L,respectively.Conclusions The concentration of (1,3)-β-D-glucan in the tears increases in the eyes with fungal keratitis and drops to normal range at 28 days after PKP,indicating that the antifungal eyedrops should be applied until 4 weeks after PKP,and this is an optimal timing of using corticosteroid eyedrops to resist reject reaction.

OBJECTIVE To probe the pathogen′s distribution of ventilator-associated pneumonia(VAP),in order to offer the evidence of clinical therapy,prevent the onset of VAP and apply the antibiotics reasonably.METHODS We applied the methods of etiology,microscopic identification,bacteria culturing etc on 74 mechanical ventilation patients,and analyzed the etiology of early-onset and late-onset VAP in contrast.RESULTS Totally 121 pathogens were cultivated altogether in all 74 VAP patients.In the 36 pathogens which were cultivated from 29 early-onset VAP patients,there were 66.67% of simple culture(24 patients,24 strains) and 33.33% of co-culture(5 patients,12 strains),and in the 85 pathogens which were cultivated from 45 late-onset VAP patients there were 17.64% of simple culture(15 patients,15 strains) and 82.35% of co-culture(30 patients,70 strains).The proportion of co-culture in the late-onset VAP patients was prominantly higher than that in the early-onset ones(?2=27.821,P
