Objective To investigate the evaluation of the employing hospital about nursing undergraduate students,to understand the actual working capacity of graduates and explore the quality requirement and individual needs of nuring undergraduates according to the findings,to improve the quality of nursing undergraduates and personnel training specifications.Methods The self-evaluation questionnaires on nursing undergraduates was used to investigate eight hospitals which accepted three or more graduates of our college by letter investigation.Results The employing hospital had the highest satisfaction degree on the moral character and working attitude,respectively 98.1%and 96.2%;the satisfaction degree of management and research capability was the lowest,respectively 81.0%and 80.0%. Conclusions Overall assessment of the quality of graduates is better,the graduates' clinical competence,interpersonal relations and psychological quality is satisfactory,nursing skills and adaptability should be improved;foreign language,scientific research,administration and management capacity is rehtively weak.In the future,the college should adapt to the reeds of employers in the teaching process,strengthening the training of practical ability and adaptability,using appropriate methods to enhance research and foreign language skills,appropriately adjust training goal of undergraduates.

Results There are 10 items having the most significant influence, 10 items having more obvious influence the last 7items.Conclusion It can improve all aspects'ability of the students effectively through carrying out the simulation interview pertinence, and can help the students find job successfully.

[Objective] To retrospectively study and discuss the indications,surgical techniques and effect of treating hallux valgus with modified Austin operation-Chevron-Gerbert osteotomy or Chevron-Youngswick osteotomy.[Method]From October 1998 to April 2006,34 patients(62 feet)with hallux valgus were treated with modified Austin operation.The X-ray films of all patients were collected preoperatively,two weeks postoperatively and during the follow-up.The hallux valgus angle(HVA),intermetataral angle(IMA),proximal articular set angle(PASA)and distal articular set angle(DASA)were measured and analyzed on radiogram.[Result]All patients were followed up for 1-8 years(mean 3.6 years).HVA before and after surgery was 33.50??1.02?and 13.6??0.826 respectively.IMA was 16.0??0.837?before and 8.6??1.078 after surgery.AOFAS score was 44.8?5.7 before,and 87.6 4.2 after surgery.Significant difference was found between the results.According to AOFAS rating system,46 feets had a excellent result and 10 feet had a good result and the other 5 feet had a fair result.The rate of excellent or good results was 90.3%.[Conclusion]The modified Austin operation is a good,simple and reliable operation means for treatment of hallux valgus,which especially applies to severe hallux valgus with big PASA.The adductor hallucis or the sesamoid is not necessarily interfered in patients with slight or moderate hallux valgus.

Objective: To prepare the conjugate of supcrantigen (SAg) staphylococcal enterotoxin A (SEA) and monoclonal antibody (McAb) against human hepatocellular carcinoma HAbl8 F(ab' )_(2) fragment and to investigate the anti-human hepatoma effect of peripheral blood mononuclear cells (PBMC) targeted by HAbl8 F(ab' )i-SEA. Methods: McAb HAbl8 was extracted and its F(ab' )_(2) fragment was prepared with papain; the conjugate HAblS F(ab' )_(2)-SEA was prepared with N-succinimidyl-3-(2-pyridyldithio) propionate (SPDP); eveny collected peak after purification was identified with gel chromatography; the activity of antibody in the conjugate was identified with immunohistocheinical ABC method; the anti-hepatoma effect of PBMC targeted by HAbl8 F(ab' )_(2)-SEA was observed with MTT method. Results: The conjugate HAbl8 F(ab' )_(2)-SEA was prepared successfully and it had obvious effect of targeting PBMC to kill hepatoma cells, and this effect is correlated positively with the dose of HAbl8 F(ab')_(2)-SEA. Control groups had no such effect. Conclusion: Targeting therapy of hepatoma with McAb-SAg conjugate might be a kind of hopeful model of hepatoma im-munotherapy.

The incidence of toileting problems is associated with the level of intellectual disability,and more common among the children with severe intellectual disability.This paper would review the classification,prevalence,consequences,origins of toileting problems,and also include the descriptions,assessment and practical considerations of behavioral interventions.

Objective To invstigate the effect of high dose X-ray irradiation on the expression of multidrug resistance-1 (MDR1), Bcl-2, MMP7 genes. Methods A nasopharyngeal carcinoma cell line,CNE1, were irradiated with a total dose of 50 Gy. The resistance to the cisplatin of CNE1 cells and the irradiated CNE1 (CNE1 R) cells was detected by MTT. mRNAs expression of MDR1 , Bcl-2 and MMP7 was measured by quantitative RT-PCR. Results The expression of MDR1 increased in CNE1 R cells. The semiquantitative A value of MDR1 mRNA was 0.47 ±0.04, and the value of CNE1R cells (1st, 7th, 21st,28th, 35th, 42nd and 49th days after irradiation) were 0.67 ± 0. 06 (t = -5.44, P = 0. 003) ,0.70 ± 0. 01(t=-5.90,P=0. 002),0.73±0. 01(t= -6. 45,P=0. 001) ,0. 67 ± 0. 03 (t= -3.97,P=0.011),0.65 ±0.01(t = -4.43,P=0. 007),0. 62±0. 05(t= -2. 64,P=0.046) and 0.62 ±0.02(t = -3.34,P=0.021), respectively. Bcl-2 mRNA expression were 0.55 ±0.02 and 1.05 ±0.04(t = -9.93,P=0. 000) and MMP7 mRNA expression were 0.51 ±0.01 and 0.82 ±0.02(t = -8.51,P=0.000) in CNE1and CNE1 R cells. Conclusions The MDR1 expression was increased after a total dose of50 Gy irradiation,which may be related to the synchronous change of Bcl-2 and MMP7 genes.

Otransplantation is a new subject which is developed so rapid that usually over the development of medical ethics.The shortage of organ supplement made organ transplantation face the challenge of medical ethics.Live organ donation has become a focal point of medical ethics in organ transplantation.It is necessary to eliminate all kinds of human organ commercialization and illegal transaction.We need pay more attention in the medical ethics issue about organ transplant,especially about live organ donation.Here is about the survey of medical ethics on live organ donation in People's Liberation Army No.181 Hospital.

Objective Analysis of MRI image of lateral ventricular subependymomas to improve our recognition of radiology manifestation of the disease. Methods Clinical data and MRI findings of 6 patients with subependymomas proved by surgical pathology, observed from January 2007 to June 2013, were analyzed retrospectively. Results Six patients (4 males and 2 females) presented with headache and dizziness. Among these 6 patients, tumor developed in right lateral ventri-cle in three patients, in left lateral ventricle in 2 patients and in frontal of dual lateral ventricle in one patient. In MRI image, tumors showed iso-intense to hypointense to normal white matter on T1-weighted and DWI images, hyperintense on T2-weighted and FLAIR. Mild or no enhancement was noted in most cases. MRS showed findings consistent with low-grade tu-mor, with a normal choline peak and depressed N-acetyl-aspartate peak. Conclusion Lateral ventricular subependymo-mas have characteristic MRI features and multi-direction images are helpful for diagnosis.

Objective To prepare a targeted antitumor drug delivery system using large-inner-diameter multi-walled carbon nanotubes (LID-MWCNTs) for sustained release and to study its performance. Methods LID-MWCNTs were puri?fied and oxidized,then use nanocarriers and USTs as homologous blockers. Folic acid and fluorescent labels were conjugat?ed onto the external surfaces of nanocarriers. CDDP (cisplatin) was encapsulated and ultrashort tubes (USTs) were employed to block the drug entry/exit paths. The microstructure of resulted drug delivery system (DDS) was observed, while drug load?ing efficiency and drug release profile in vitro were determined. The tumor-targeting property and cytotoxicity of DDS were also assessed. Results LID-MWCNT based sustained release targeted drug delivery system was established. Drug loading efficiency of CDDP@UST-FA-LID-MWCNTs was as high as 70.97%. A typical biphasic sustained release pattern was dem?onstrated, and the accumulating release time was 18 h. DDS exhibited a certain kind of tumor-targeting property, and inhibit?ed proliferation of tumor cells in a dose-dependent manner. Conclusion CDDP@UST-FA-LID-MWCNT drug delivery system exhibited an improved drug loading efficiency and a sustained drug release profile. It could specifically target the tu?mor cells and had a significant antitumor effect.
