AIM: To study the expression and the role of neurokinin-1 receptor(NK-1R) and neurokinin-2 receptor (NK-2R) in distal ileum during acute necrotizing pancreatitis(ANP).METHODS: 130 adult Sprague-Dawley rats were divided into 2 groups: the rats in ANP group( n=80 ) were induced by the retrograde intraductal infusion of 5% sodium taurocholate. The rats in sham operation control group ( n=50 ) received laparotomy only. Reverse transcription polymerase chain reaction (RT-PCR) was used to determine the mRNA expression of NK-1R and NK-2R, Western blot was used to investigate expression level of NK-1R.RESULTS: NK-1R and NK-2R mRNA levels were enhanced in the distal ileum of ANP rats compared with controls. Western blot revealed stronger NK-1R immunoreactivity exited in intestinal mucosa in ANP rats. The overexpression of NK-1R was associated with mucosal pathological score( r=0.77,P

AIM: To investigate the expression of neurok inin-2 receptor (NK-2R) in normal pancreas and chronic pancreatitis (CP) tissues. The relation of expres sion of NK-2R with pain in CP was also evaluated. METHODS: CP tis sues were ob tained from 18 men and 7 women undergoing pancreatic head resection as a result of CP. Normal human pancreatic tissues were obtained from 20 patients (11 males/ 9 females). Real-time quantitative reverse transcription polymerase chain reacti on was used to determine the mRNA expression of NK-2R, Western blot analysis was used to determine its protein expression level, and immunohistochemistry was us ed to localize expression site of NK-2R protein. NK-2R mRNA level and pain were also analysed whether correlation exists. RESULTS: NK-2R mRNA and p rotein level were enhanced expressed in CP tissue samples compared with normal pancreas. Ove rexpression of NK-2R was related to the intensity ( r=0 59, P

Objective To investigate the manifestations of CT and MRI images of paranasal sinuses sarcoma, improve the accuracy of diagnosis. Methods Make retrospective analysis of our hospital from January 2008 to January 2014,36 patients with pathologically confirmed nasal sinuses sarcoma in patients with CT and MRI imaging data, to explore the value of imaging diagnosis. Results The MRI sarcoma typically presents with slight long T1 and slight long T2 signal,enhanced moderately enhanced. 36 cases of lesions center located in the sphenoid region, in maxillary sinus in 6 cas-es. The CT diagnosis of paranasal sinuses sarcoma of the lesion was a total of 27 cases(75.00%),the MRI can provide the diagnosis of paranasal sinuses sarcoma in 35 cases(97.22%),two methods had significant difference (χ2=7.43,P<0.05). Conclusion CT can effectively show the sinus bone destruction, MRI could clearly display the lesion's extent,the combination of image can provide more comprehensive information for the diagnosis and treatment of the Sinus.

【Objective】 To investigate the status of professional identity and job satisfaction of blood transfusion physicians in clinical in Tianjin, and to analyze the influencing factors. 【Methods】 The status of professional identity and job satisfaction of physicians in Blood Transfusion Department or Blood Bank of hospitals in Tianjin was investigated and analyzed by online questionnaire survey. 【Results】 The average score of professional identity and job satisfaction was(3.96±0.46) and (3.11±0.86), respectively. Pearson analysis was used for correlation analysis, and the results showed that the dimensions of professional identity and job satisfaction were significantly positively correlated(P<0.05). The results of regression analysis showed that income level was a significant factor influencing the professional identity of blood transfusion physicians(P<0.05), as low income level decreased the professional identity of them. Age also was a significant factor influencing the job satisfaction of blood transfusion workers(P<0.05), as the increase of age would reduce the job satisfaction of them. 【Conclusion】 The level of professional identity and job satisfaction of blood transfusion physicians in Tianjin is generally high, and income level and age are the risk factors affecting their professional identity and job satisfaction.
