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 explore the combined treatment rigimen of gonococcal prostatitis.　Methods:The combined treament of improving remedy of antibiotics was used by taking orally the Chinese medicine and herb medicine demibain in 54 cases of patient with gonococcal prostatitis. compared with controlled group.　Results:The curing rate of combined treatment group was 74.1%, being higher significantly than that of controlled group (P＜0.05).　Conclusion:The combined treatment is better than the controlled group in curing gonococcal prostatitis and preventing recurrence.

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 Establishment and characterization of healthy donor's ??T cell clones.Methods ??T cells were cloned by limiting dilution after positive sorting with 60Co irradiated allogeneic PBMC as feeder cells.Flow cytometry analysis and molecular biology technique were then used to identify ??T cell clones.MTT assay was used to verify their proliferation after incubated with epitope peptides recognized by ??T cells.Results A ??T cell clone had been established.The subtype of this clone was V ?9 V ?2 without expression of CD4 and CD8.Further studies indicated that epitope peptide EP6 could not only specifically bind to ??T cell clone but also trigger the proliferation of ??T cell clone.Conclusion A healthy donor's ??T cell clone was successfully established,which laid a solid foundation for further study on ??T cells.

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.

The authors reviewed the breeding situations of mites in homes,including rates,distribution,seasonal variation and common species,and the diagnosis and treatment of the allergic diseases caused by mites,as well as their parasitizing in gastrointestinal tract,lungs,urinary tract and other organs.In the end,the measurements for control of mites in homes were demonstrated.

Objective To investigate the effect of pyrrolidine dithiocarbamate (PDTC) on the proliferation and expression of IL-8 of SKOV3 cells in acid environment,and the role of nuclear factor ?B (NF-?B) in the process.Methods SKOV3 cell lines were divided into 5 groups: normal culture group,acid environment group,acid environment plus PDTC groups (25,50 and 100 mol?L-1 PDTC).All the SKOV3 cells were cultivated for 12 h.The effect of PDTC on the proliferation of SKOV3 in the acid environment was determined by MTT,the content of IL-8 protein in the culture supernatant was detected by ELISA and the expression of NF-?B protein was measured by Western blotting.Results The IL-8 expression level in the acid environment was(1 384.211?42.320) ng?L-1.there was significant difference compared with normal group(617.505 ng?L-1?47.850 ng?L-1)(P

Objective To study the uptaking characteristics of puerarin in Caco-2 model system. Methods The transepithelial transporting character of puerarin across Caco-2 cells was investigated by changing the concentration, temperature of drug and using appropriate inhibitors. Results The transport of puerarin across Caco-2 cell monolayers was directional. With the increase of the concentration of pue-rarin, the permeability direction ratio (PDR) was decreased from 2.1 to 1.4. With the increase of temperature, PDR was increased. When the metabolic inhibitors, KCN and 2,4-dinitrophenol, were added, the PDR was decreased from 1.7 to 1.0 and 1.2, respectively. When 100 mg/L Verapamil was added, the permeability coefficient of apical to basolateral was increased from (0.84?0.18)?10-7 cm/s to (1.01?0.17)?10-7 cm/s, and the permeability coefficient of basolateral to apical was decreased from (1.43?0.18)?10-7 cm/s to (1.11?0.24)?10-7 cm/s. Conclusion The evacuation by P-glycoprotein affects the puerarin transepithelial transport across Caco-2 cells.
