Objective To explore the influence of catheterization for urinary tract infections and the importance of humanistic nursing. Methods Totally 248 patients who were admitted into our hospital from February 2013 to April 2014 were randomly divided into two groups. Patients in the control group (117 cases) were given spray fungicide and regular disinfection of urethra by nursing staff, and patients in the observation group (131 cases) were nursed by themselves or their family after been taught the way of spraying fungicide and cleaning. Ana-lyzed the psychological status, routine urine, urinary tract infections, nursing job satisfaction of the patients, and the relevant data were ana-lyzed by SPSS 17. 0 software. Results The third day after placing urinary catheter urethra, the relevant nursing can reduce the rate of urina-ry tract infections in patients. the difference of the two groups was statistically significant (P<0. 05). The rate of urinary tract infections at the seventh day after placing urinary catheter urethra was 39. 69% in the observation group and 41. 03% in the control group, the difference of the two groups was not statistically significant (P >0. 05). Infection rate of male patients (29. 01%) is higher than female patients (10. 69%). The satisfaction rate of urethra care in the observation group was 87. 79%, and the satisfaction rate of other project were all higher than 92. 5%. The satisfaction rate of urinary tract nursing check in the control group was 79. 49%, and the satisfaction rate of nurse-patient communication was 83. 76%. It was found that the difference of communication between nurses and patients, service attitude and the urethra care were statistically significant. Conclusion It can reduce the rate of urinary tract infection after placing urinary catheter in pa-tients for 7 days and nursed by patients themselves with spraying fungicide and cleaning. Strengthen the humanistic nursing care can improve nursing satisfaction.

Objective To explore the cytotoxicity of the cytotoxic T lymphocyte (CTL) induced by SW480 sonicate sensitized dendritic cells (DC) on the colon cancer cell line SW480. Methods PBMC were separated from the HLA-A*0201 donor and DC were cultured with rhGM-CSF, rhIL-4 and rhTNF-α. The same donor's primary CTL were stimulated by DC loaded with SW480 sonicate. The cytotoxicity of CTL on SW480 (HLA-A*0201 positive) and K562 (HLA-A*0201 negative) was determined by the MTT method. Results The cytotoxicity of the CTL on SW480 was stronger than that on K562 (P ＜0.05). Conclusion The DC vaccine can stimulate specific CTL which can trigger cytotoxic activity on the target cells and this cytotoxicity is related to MHC restriction.

Objective To investigate the clinical efficacy of heat-sensitive point moxibustion in treating functional dyspepsia. Methods Fifty-six patients with functional dyspepsia were randomly allocated to treatment and control groups, 28 cases each. The treatment group received heat-sensitive point moxibustion and the control group took domperidone tablets. The symptoms were scored and plasma motilin was measured in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results The total efficacy rate was 89.3% in the treatment group and 82.1% in the control group; there was a statistically significant difference between the two groups (P<0.05). There were statistically significant pre-/post-treatment differences in the symptom score and plasma motilin in the two groups (P<0.05). There were statistically significant post-treatment differences in the symptom score and plasma motilin between the treatment and control groups (P<0.05).Conclusion Heat-sensitive point moxibustion is an effective way to treat functional dyspepsia.

Objective To evaluate the effect of managed health education on psychological and nutritional status of patients with HBV-related cirrhosis and ascites.Methods One hundred and twenty one patents with decompensated HBV-related cirrhosis were enrolled for health education and randomly divided into two groups:61 patients received managed health education (trial group) and 60 received conventional health education (control group).In control group patients were informed with their condition and diet note by medical orders.In control group the hepatologists evaluated the baseline condition,nutritional status and quality of life,set up personal files of patients and followed up with communication and counselling periodically from June 2010 to August 2012.The psychological conditions were assessed with self-rating anxiety scale (SAS) and self-rating depression scale (SDS) ; nutritional status was assessed with triceps skinfold thickness (TSF) and mid-arm muscle circumference (MAMC) and the quality of life was assessed with MOS 36-item shoort from healthy survey (SF-36).Results Before health education,there was no statistical difference in the scores of SAS,SDS,TSF,SF-36 and blood Hb,albumin (Alb) levels between two groups.After health education,scores of SAS and SDS were decreased in both groups (P ＜ 0.0l),however,which in trial group were lower than those in control group (39.9 ±8.8 vs.49.0 ±9.4 and 40.6 ± 8.8 vs.51.9 ± 10.1 respectively,both P ＜0.01).The TSF scores and blood Hb and Alb levels in trial group were higher than those in control group (P ＜ 0.05).The accunulated scores of 8 dimensions in SF-36 forms in trial group were significantly higher than those in control group (P ＜ 0.01).Conclusion The managed health education model can better release psychological pressures,decrease mental disorders,elevate nutrition status,promote health and improve quality of life than conventional health education for patients with HBV-related cirrhosis and ascites.

A questionnaire and telephone survey was conducted on 246 patients with chronic liver diseases in the Outpatient Clinic from August 2010 to May 2011.The distribution of diseases and the causes of losing follow-up were analyzed. Most subjects in this survey (182/246,74.0％ ) were patients with chronic viral hepatitis( HBV or HCV)and cirrhosis; and their follow-up status was better than others (X2 =12.382,P ＜ 0.05). There were no differences in gender( X2 =10.137,P ＞ 0.05),but significant differences in age ( X2 =31.783,P ＜ 0.05 ) and educational levels ( X2 =32.803,P ＜ 0.05 ) between patients with chronic viral hepatitis and cirrhosis and patients with other liver diseases.The main causes of losing follow-up were neglect of disease by patients (38.3％) and lack of good communication between doctors and patients ( 18.3％ ).It is important to reinforce the understanding and awareness of chronic liver diseases for patients.

Objective To explore the value of transthoracic echocardiography in diagnosis of univentricle and analyze the sonogram typing. Methods The results of 66 patients with univentricle were reviewed retrospectively,and analayzed their typing connected with the reports in the literature. Results There were 3 ultrasonic types in 66 cases:①Type A(single left ventricle) 19 cases,single ventricle with left ventricular shape,residual cavity in front of it. ②Type B(single right ventricle) 38 cases, single ventricle with right ventricular form,and residual cavity in the rear.③Type C (solitary single-ventricle) 9 cases,there was only one ventricle. Thirty-one of them were treated surgically, 5 cases without operation had MRI or cardiac catheterization examination and the remaining 26 patients were only observed by echocardiography,the positive rate of diagnosis in type was 100%, the results were compared with cardiac catheterization or MRI examination and the operation: 1 cases of mixed type total anomalous pulmonary venous connection was misdiagnosed as heart-type total anomalous pulmonary venous drainage. But 1 case of descending aorta limitations narrow complicated patent ductus arteriosus(PDA), PDA was missed. The rest were completely correct diagnosis. Conclusions The transthoracic echocardiography can be used to evaluate types and all containing malformations of univentricle,and offers reliable information for operation.

BACKGROUND:Stem cels are induced to differentiate into endothelial-like cels that can be used for the treatment of diabetic lower extremity vascular disease. However, it is unclear whether these endothelial-like cels can completely replace endothelial cels to improve vascular disease and what are the differences between endothelial-like cels and endothelial cels. OBJECTIVE:To explore the differences and similarities between endothelial-like cels and human umbilical vein endothelial cels in the aspects of morphology, function, and viability. METHODS:Umbilical cord mesenchymal stem cels and umbilical vein endothelial cels were isolated, cultured and identified using flow cytometry and immunohistochemical method. Isolated umbilical cord mesenchymal stem cels were induced in DMEM-LG/F12 containing 10 μg/L vascular endothelial growth factor, 10 μg/L basic
fibroblast growth factor and 2% fetal bovine serum to differentiate into endothelial-like cels folowed by immunohistochemical identification. To compare endothelial-like cels with human umbilical vein endothelial cels, cel migration detection, active substance measurement and three-dimensional angiogenesis test were performed. RESULTS AND CONCLUSION:Isolated umbilical cord mesenchymal stem cels strongly expressed the surface markers of mesenchymal stem cels, and human umbilical vein endothelial cels strongly expressed CD31 and VWF. After induction, the umbilical cord mesenchymal stem cels were identified to highly express CD31 and VWF. Through cel migration, active substance and three-dimensional angiogenesis tests, endothelial-like cels were similar to endothelial cels in the function and activity, and superior to endothelial cels.
