ObjectiveTo explore the nursing students'puzzles about career planning,and provide a basis for the training.MethodsA qualitative research was conducted on 14 university nursing interns by in-depth interview and observing.The whole interview was noted.The data was analyzed according to Colaizzi's phenomenological procedure.ResultsThe experience could be classified into four aspects,including hazy understanding of career planning,lack of understanding of themselves,limited ca reer identity and lack of social cognition.ConclusionNursing educators should enhance the training against the nursing students'puzzles and make sure they can make a good career planning.

Objective To observe the effects of different gastrointestinal reconstruction methods after dis -tal subtotal gastrectomy on nutritional condition and blood glucose in patients with type 2 diabetes ( T2DM) and gastric cancer.Methods 88 patients with T2DM and gastric cancer undergoing radial distal gastrectomy were studied and among them 43 patients had Billroth I gastrointestinal reconstruction , 22 patients had Billroth II gas-trointestinal reconstruction and 23 patients had Roux-en-Y gastrointestinal reconstruction .Body mass index ( BMI) , serum albumin and prealbumin of the 3 groups were measured preoperatively and 1 year after surgery . The patients were followed up .Results There was no significant difference among the 3 groups in preoperative values(P>0.05).One year after surgery, BMI, serum albumin and peralbumin in the 3 groups had different de-grees of reduction , but showed no statistical difference ( P>0.05 ) .The effective rate of diabetes control was 18.60%in Billroth I group , 72.73%in Billroth II group , and 73.91% in Roux-en-Y group and the difference had statistical significance(χ2 =17.390 3,P<0.05).The effective rates of diabetes control in Billroth II group and Roux-en-Y group were higher than that in Billroth I group (χ2 =18.340 9,P<0.05;χ2 =19.480 4,P<0.05), and there was no evident difference between Billroth II group and Roux-en-Y group(χ2 =0.008 1,P=0.928 4).Conclusion Billroth II and Roux-en-Y gastrointestinal reconstruction can improve glycemic metabo-lism of patients with T2DM and gastric cancer without significantly reducing the nutrition status .

Objective To assess the effect of swallowing function training on dysphagia.Methods66 patientswith dysphagia were randomly divided into training group and control group. The swallowing function of the two groupswere evaluated before and after training.ResultsThe effective rate of training group is 78.1% which is higherthan control group (P< 0.01).ConclusionSwallowing function training can significantly improve swallowing function and activity of daily living of the patients with dysphagia.

Objective To study the mechanism of myocardical aging. Methods Wistar rats used were divided aging group (22 months old) and adult group (7 months old). Qualitative morphological changes of organelles of myocardium were observed by TEM. Quantitative morphological changes of organelles of myocardium were determined by stereological method, Ca 2+ regulation of organelles of myocardium were analysed by EDS. Results Compared with adult group, aging group:(1) The nuclei were indented, myofibril were arranged irregularly, intercalated disk were separated, mitochondria and sarcoplasmic reticulum were swelled, lipofuscin and residual body were increased. (2) The volume of myocardium not occupied by myocyte were increased, the volume density of mitochondria and sarcoplasmic reticulum were reduced, specific surface of outer membrance of mitochondria inter membrane plus cristae of mitochondria and the membrane of sarcoplasmic reticulum were also reduced. (3) Ca 2+ in myofibril and mitochondria were increased, but Ca 2+ in sarcoplasmic reticulum were decreased. Conclusion The contractility of aging myocardium were declined, the morphological changes and Ca 2+ regulation of mitochondria and sarcoplasmic reticulum might be directly related to myocardical aging.

OBJECTIVE To investigate the methods of promoting nosocomial infection administration in laminar airflow(LAF) operation department,based on the theory of air microbe and object surface microbe. METHODS To begin with the construction standard of LAF operation department,to discuss difficult,complicating,professional and legal characteristics of nosocomial infection administration of LAF operating room. RESULTS It was a solid base of promoting nosocomial infection administrition to specify strictly the standard for the LAF operation department built;it was a vital link of promoting nosocomial infection administrition to take part in inspecting the engineering quality of LAF operation department;it is an effective means of LAF nosocomial infection administrition to carry out the supervision and control to the LAF operation department daily;it was the essense of promoting nosocomial infection administrition to make efforts to innovate the modern administration pattern in LAF operation department. CONCLUSIONS The management of hospital infection in the LAF operation department must emphasize the comprehensive measure of the all-directional germ control,make standard of decontamination of air conditioning guarantee system and carry out the whole process supervision.

OBJECTIVE To raise the sci-tech components of the infection control work guided by evidence-based medicine.METHODS To apply the basic principle of evidence-based medicine in the actual work and carry on the argument and analyses. RESULTS The implement of these measures under the guidance of evidence-based medicine could raise the level of the infection control work effectively,which included consult rule of the Hospital Infection Committee,collection of information in network,evaluation and analysis of the examination result of clinical microbiological laboratory,integreted and individualized dynamic monitoring method and diversity and whole process intervention measure.CONCLUSIONS The infection control work guided by evidence-based medicine can reduce the occurrence of the hospital infection effectively.

The expression patterns of 5-hydroxytryptamine(5-HT),gastrin(Gas),β-endorphin(End),somatostatin(SS),vasoactive intestinal peptide(VIP),glucagon(Glu) and neuropeptide Y(NPY)-positive cells in the duck thymus were studied by the immunohistochemical method associated with image analysis.The result shows that these 7 kinds of neuroendocrine cells with strong intensity were differentially detected in the duck thymus.The End-positive cells were abundantly expressed in the thymic cortex,whereas the Gas,5-HT,SS,VIP,Glu and NPY ones were more frequent in the medullary and around the corticomedullary junction.Except Glu,the other 6 kinds of neuroendocrine substances with various intensity were expressed in the cells of thymic corpuscles.The observation demonstrated that the duck thymus is not only a primary lymphatic organ,but also has important neuroendocrine functions.The End-positive cells in the thymus may play crucial roles in the development of immature T-lymphocytes.The neuroendocrine cells with a predominant distribution in the medulla and around the corticomedullary junction might facilitate exerting their influence via an endocrine,autocrine or paracrine pathways on the function of mature T-cells.The possible roles of thymic corpuscles are also discussed.

Objective To investigate the diagnosis and treatment of injury in choledocho-pancreatico-duodenal junction. Methods The clinical data of 6 patients with injury in choledocho-pancreatico-duodenal junction who had been admitted to Beijing Hospital from January 2000 to January 2008 were retrospectively analyzed. Results Of the 6 patients, 4 were diagnosed according to the intraoperative findings, cholangiography and fiber cholangioscopy. The 4 patients were cured after suture of the perforation in the choledocho-pancreatico-duodenal junction, T-tube drainage and abdominal drainage. Two patients developed severe abdominal and retroperitoneal infection and other complications after operation, and were diagnosed by cholangiography and fiber cholangioscopy. Of the 2 patients, 1 was cured and 1 died after multiple drainage procedures and debridement. Conclusions Diagnosis and treatment in the early stage are crucial for the curative purpose. Cholangingraphy and fiber cholangioscopy are effective in the diagnosis of injury in choledocho-pancreatico-duodenal junction. The suture of the perforation in the choledocho-pancreatico-duodenal junction, T-tube drainage and abdominal drainage should be chosen for patients who are diagnosed during primary operation. For patients with abdominal and retroperitoneal abscess and cellulitis, drainage and debridement should be performed, and biliopancreatic diversion and duodenal diverticularizatian are applied to patients when necessary.
