ObjectiveTo understand the nursing undergraduates' graduation thesis writing,to provide basis for the revised management plan and improve the overall quality of graduation thesis.Methods A self-designed questionnaire was given to 158 four-year program nursing graduates of Grade 2006 by group and the questionnaires were collected timely and analyzed with SPSS 17.0.Results63.19％ of students thought it necessary to write thesis,86.71％ thought internship beneficial for wrting and 64.6％ hoped to finish the thesis writing before the practice because of great pressure.ConclusionStudents' recognition degree to graduation thesis directly affects the quality of thesis writing.A reasonable teaching plan should be made and school resources should be fully used to improve the quality of thesis writing.

Toll like receptors(TLRs) , a pattern conservative receptor superfamily are found on mammalian cell surface over the last decade. TLRs recognize distinct pathogen - associated molecular patterns, which can lead not only to the responses of the innate immunity but also to the development of the antigenspecific adaptive immunity. The expression of TLRs have changed in some carcinomas, besides, microbial composition and drugs mediate the tumor immunotherapy by the way of TLRs signal transduction. Consequently , deep studies on TLRs will provide new approaches for tumor immunotherapy.

ObjectiveTo investigate the factors influencing pelvic traction used for prolapse of lumbar intervertebral disc (PLID).Methods200 PLID patients were treated by pelvic traction 30 min/d for 3 courses (10 days as one course).ResultsAfter treatment, therapeutic effects were prominent in 58 cases, effective in 78 cases, improvable in 34 cases, and invalid in 30 cases.ConclusionThere are definite indications in the treatment of PLID with pelvic traction. In order to gain satisfied therapeutic effect, appropriate cases should be selected for pelvic traction.

Objective To explore the effect of methylprednisolone combined with interferon in the treatment patients with relapse remitting multiple sclerosis.Methods 90 patients with relapse remitting multiple sclerosis were randomly divided into experimental group and treatment group.The experimental group during the acute stage with methylprednisolone pulse therapy,remission with interferon β (IFN-β) treatment; the control group only in the acute phase with methylprednisolone pulse therapy.Results The total effective rate of methylprednisolone pulse therapy in the acute stage was 98.9％.Experimental group during the treatment with IFN-β1α,relapse rate was 30.2％ ;patients in the control group were followed up for two years,the recurrence rate was 53.3％.Experimental group and control group was significantly different ( P ＜ 0.05 ),the experimental group was significantly lower than the control group.Conclusion For relapsing-remitting MS,using MPPT could relieve acute symptom in the acute stage,and in remission using of IFN-β1α relapse prevention was a good choice for clinicians.

OBJECTIVE:To optimize the preparation technology of cefixime suspension and study its stability.METHODS:The effects of hydroxypropyl cellulose,xanthan gum and sodium lauryl sulfate in different proportions on the sedimentation volume ratios of the suspensions were investigated by orthogonal experiments to optimize the preparation technology.The stability of the preparation was studied by accelerated test.RESULTS:The optimum preparation technology for cefixime suspension was as follows:the proportions of sodium dodecylsulfate,xanthan gum,and hydroxy-propyl methyl cellulose(HPMC) were 10%,20%,and 15%,respectively.The prepared suspension had simple formula and good stability,with all indexes up to the quality specification for suspension.CONCLUSION:The suspension prepared in accordance with this formula was able to meet the requirements of Chinese Pharmacopoeia on dry suspension.

Idiopathic Refractory Nephrotic Syndrome (IRNS) has been an intractable problem in clinical treatment .Anti CD20 monoclonal antibody is a new type of immunosuppressive agent , which can induce the lysis and apoptosis of B cells .Significant-ly, it improves the prognosis of IRNS patients .In recent years, a number of case studies and clinical trials have been conducted on the effectiveness of anti CD20 monoclonal antibody in the treatment of children with IRNS .In this paper, the mechanism, clinical applica-tion, adverse effects and problems in the study of anti CD 20 monoclonal antibody in IRNS will be reviewed .

OBJECTIVE:To observe the efficacy and safety of atorvastatin in the treatment of hypertension with unstable angi-na. METHODS:80 patients with hypertension with unstable angina were randomly divided into control group and treatment group. All patients were given anti-platelet aggregation and other conventional treatment;based on it,control group was orally treated with Amlodipine besylate tablet 5 mg,once a day+Metoprolol tartrate controlled-release tablet 25 mg,twice a day+Isosorbide dini-trate injection 10 ml by intravenous infusion,twice a day;treatment group was additionally treated with Atorvastatin calcium tablet 20 mg,orally,qd. 3 months was a treatment course,and it lasted 6 courses. Clinical efficacy,and systolic blood pressure,diastol-ic blood pressure,angina frequency and duration,changes of TC,TG,LDL,HDL levels before and after treatment and adverse reac-tions in 2 groups were observed. RESULTS:Total effective rate in treatment group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,systolic blood pressure and diastolic blood pressure in 2 groups were significantly lower or shorter than before,the difference was statistically significant(P<0.05),however,there was no signifi-cant difference between 2 groups(P>0.05);angina frequency and duration were significantly lower than before,and treatment group was lower than control group,TC,TG and LDL in treatment group were significantly lower than before and control group, HDL was higher than before and control group,the differences were statistically significant(P<0.05),there was no significant dif-ference between before and after treatment in control group(P>0.05). There was no significant difference in the adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Based on the conventional treatment, atorvastatin can effectively reduce the long-term angina frequency and duration of patients with hypertension with unstable angina,improve the ischemia myocardial and reduce the lipid levels with good safety.

Objective To explore the diagnostic value of MRI in female non-genital origin masses in pelvis.Methods The MRI features of female non-genital origin masses confirmed by surgery pathology in 15 patients were analyzed retrospectively.Results Preoperative MRI showed that 10 masses were mixed type,3 masses were solid,and other 2 masses were cystic,5 masess were mis-diagnosed as genital origin tumors.Pathological results revealed the masses in 6 patients from digestive system,5 from abdominal and retroperitoneal tumor,and other 4 from other tumors,including small intestine stromal tumors in 4 patients,sigmoid colon ade-nocarcinoma in 1,mucinous cystadenoma of the appendix in 1 patients,mesenteric liposarcoma in 1 schwannomas in 2,retroperitoneal fibromatosis in 1,hibernoma in 1,gossypiboma in 2,lymphatic cyst in 1,and lymphoma in 1.Conclusion Female non-genital origin masses in pelvis are easily misdiagnosed as ovarian tumor before operation,and other clinical features should be paid attention in or-der to reduce misdiagnosis.

Congenital bile duct dilatation may occur in any part of the biliary tree,and the diagnosis and treatment of lesions involving the intrahepatic bile duct is the most challenging issue.Surgical operation plays a dominant role in the management of congenital bile duct dilatation,with the purposes of relieving symptoms and preventing disease progression and malignant transformation.Surgical principles are radical resection of lesions and reconstruction of unobstructed bile drainage.Hepatectomy is the main surgical procedure for congenital bile duct dilatation with involvement of the intrahepatic bile duct,and liver transplantation can be used for diffuse lesions.Therefore,we believe that hepatectomy and early intervention will maximize patients' benefits.
