Objective To determine the influencing factors on prognosis of neonatal necrotizing enterocolitis (NEC) in premature infants with a gestational age of 28-32 weeks.Methods Forty-six cases of NEC (Bell stage Ⅱ or Ⅲ) with a gestational age of 28-32 weeks admitted to Bayi Children's Hospital from January,2009 to January,2013 were analyzed retrospectively.Twenty-nine cases were assigned to the cured group and 17 cases were assigned to the poor prognosis group according to prognosis.General conditions,laboratory results,treatment and complications in the two groups were analyzed.The Chi-square test,Fisher's exact test and univariate analysis of variance were used for statistical analysis.Results There were no statistically significant differences regarding gender,average birth weight and mean age of onset between the two groups [average birth weight (1 410.52±281.59) g vs (1 266.47±280.32) g and mean age of onset:(20.79± 10.61) d vs (16.71 ±9.41) d for the cured group versus the poor prognosis group,respectively].There were no difference in changes in white blood cells and platelets between the two groups.There were six cases of positive blood culture in the poor prognosis group and none in the cured group.There were no differences in procedures such as blood transfusion and ibuprofen administration [41.4％ (12/29) vs 11/17 and 6.9％ (2/29) vs 5/17,both P＞0.05,in the cured group versus the poor prognosis group,respectively].There were significant differences in the use of Bifidobacterium between the two groups [69.0％ (20/29) vs 5/17,x2=6.758,P=0.009].Fourteen cases in the cured group and 10 cases in the poor prognosis group underwent surgery,and all 10 cases in the poor prognosis group died.Seven cases underwent repeated surgery,one infant in the cured group and six infants in the poor prognosis group and a significant difference was observed (Fisher's exact,P=0.007).A statistically significant difference in granulocyte colony-stimulating factor (G-CSF) treatment was observed between the two groups,where 15 cases in the cured group and three cases in the poor prognosis group were treated with G-CSF (x2=5.225,P＜0.05).Statistically significant differences in septicemia,patent ductus arteriosus,gastrointestinal perforation,multiple organ failure (MOF),disseminated intravascular coagulopathy (DIC) and septic shock were observed between the two groups [septicemia:44.8％ (13/29) vs 15/17,x2=8.478; patent ductus arteriosus:17.2％ (5/29) vs 9/17,x2=6.451; gastrointestinal perforation:3.4％ (1/29) vs 6/17; MOF:0.0％ (0/29) vs 5/17; DIC:0.0％ (0/29) vs 3/17; septic shock:3.4％ (1/29) vs 6/17,all P＜0.05 in the cured group versus the poor prognosis group,respectively).Conclusions Oral intestinal microbial preparations before the onset of NEC and G-CSF therapy after the onset of NEC may be protective factors in improving the prognosis of NEC,while patent ductus arteriosus,septicemia,gastrointestinal perforation,MOF,DIC and septic shock are risk factors.Emphasis should be placed on the administration of intestinal microbial agents,prevention of infection and treatment of complications.

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.

Objective To determine the inhibitive effect of interferon-a on hepatic metastasis of colon cancer. Methods Metastatic model of human colon cancer was established by orthotopic implantation of histologically intact human tumor tissue into the colon wall of nude mice.The mice were randomly divided into 4 groups:(1)Control group(receiving saline solution only);(2)5-FU treatment group;(3) IFN-?-2b treatment group;and(4)5-FU combined with IFN-?-2b treatment group(combined group). 5-FU and IFN-?-2b were given via peritoneum injection 1 time/2 days for eight weeks.The mice were killed at nine weeks.The tumors were weighed,the microvessel density(MVD) was detected,and the liver was examined histologically in order to discover the micrometastasis. Results In control group, 5-FU group,IFN-2b group and combined group,the tumor weight was(1.53?0.78)g,(0.87?0.59)g,(0.81?0.43)g and ( 0.23?0.09)g, respectively;the tumor inhibition rate was 0,43.1%,47.1% and 84.9%, respectively;the hepatic metastasis rate was 85.7%,78.6%,21.4% and 0 respectively.MVD in IFN-? group and combined group was significant lower than that in control group and 5-FU group. Conclusions IFN-? can inhibit the growth and hepatic metastasis of orthotopic implanted human colon cancer by inhibiting the tumor angiogenesis.It may be more effective when INF-? combined with cyotoxic agents.

Objective To investigate the time-effect relationship and dose-effect relationship of the expression of adenovirus mediating Smad 7 gene regulated by irradiation via Egr-1 promoter in the lung of C57BL mice. Methods Recombinant adenovirus (AD.Egr-Smad 7) was made up through replication-defective adenovirus enclosed radio-inducible elements from the Egr-1 gene promoter and cDNA encoding Smad 7. Mice infected by intratracheal instillation with AD.Egr-Smad 7 were irradiated to their whole lungs after 24 hours. 324 mice were randomly divided into 6 groups, and the lungs were harvested at different time points following irradiation with single dose of 8?Gy to observe the time-effect relationship of Smad7 gene expression with different time intervals. 108 mice randomly divided into 3 groups were irradiated respectively by different single irradiation dose and the lungs were harvested 5 hours after radiation to evaluated the dose-effect relationship of Smad 7 gene expression with different radiation doses. The expression of exogenous Smad 7 was detected by Western blot analysis. Results The expression of adenovirus mediating Smad 7 gene regulated by Egr-1 promoter could be induced by radiation markedly as compared with the control groups(P
