Objective To investigate the effect of ulinastatin on postoperative cardiac troponin I ( cTnI) in patients underwent carotid endarterectomy ( CEA) under general anesthesia. Methods Forty patients with severe symptomatic carotid artery stenosis underwent unilateral CEA under general anesthesia from January 2011 to March 2012 were divided into either a ulinastatin group or a control group according to a random number table ( n=20 in each group) . Patients in the ulinastatin group received 500 000 U of ulinastatin via veins before induction of anesthesia. The patients in the control group were given the same amount of isotonic saline. The serum concentrations of cardiac troponin I ( cTnI ) were detected before surgery and at day 1,2,and 3 after procedure. Myocardial injury was defined as the cTnI peak concentration>0. 04μg/L . Results The levels of serum cTnI before procedure and at day 1,2,and 3 after procedure in the ulinastatin group were median (M) 0. 00 (0. 00-0. 03) μg/L,0. 07 (0. 00-1. 45) μg/L,0. 01 (0. 00-1. 21)μg/L,and 0. 05 (0. 00-0. 89)μg/L,respectively;those in the control group were 0. 00 (0. 00-0. 01)μg/L,0. 00 (0. 00-1. 42)μg/L,0. 00 (0. 00-1. 39)μg/L,and 0. 00 (0. 00-1. 24)μg/L, respectively. At day 1 after procedure,6 patients ( 30%) in the control group and 11 ( 55%) in the ulinastatin group occurred myocardial injury. There was no significant difference between the two groups (P<0. 05). In all the patients with the increased cTnI levels,the peak cTnI occurred at the first day after procedure,however,they did not reach the level ( >1. 5μg/L) of indicating patients occurring myocardial infarction. Conclusion Ulinastatin may not decrease the postoperative serum cTnI levels in CEA patients under general anesthesia. For whether to the CEA patients have myocardial protective effect,more samples are needed to be confirmed.

Objective To investigate nurses' organizational career management and job satisfaction in the third-grade class-A hospital,and analyze the relationship between them.Methods A total of 576nurses were recruited by two-stage stratified random sampling method from four third-grade class-A hospitals.They were investigated with Nurses' Organizational Career Management Questionnaire and Job Satisfaction Scale.Results The mean score of nurses' organizational career management and job satisfaction was(2.94±0.52)and(3.32±0.46).There were significant differences on the scores of job satisfaction in nurses with different ages,nursing age,shift,posts,professional tifles,departments,monthly income and type of hospitals.Nurses' organizational career management was positively correlated to job satisfaction.After controlling for the demographic variables,the overall state of organizational career management could explain 34.2 percent for the variances of job satisfaction respectively.Conclusions It is suggested to pay close attention to nurses' organizational career management and take effective career management measures to improve nurses' job satisfaction so as to stabilize the nursing team and retain the excellent nurses.
