Objective To explore the relationship of course experience,course engagement and learning outcomes in medical nursing.Methods Adapted Course Experience Questionnaire and Selfestablished Course Engagement Questionnaire were used to collect data of 142 nursing undergraduates of which 126 were valid.The data were analyzed by regression analysis.Results Course experience had significant impact on course engagement,t=4.621,2.477,4.538,P＜0.01 or 0.05.Course engagement had significant impact on learning outcomes,t=2.439,P＜ 0.05.Course experience had significant impact on learning outcomes,P＜ 0.05.Conclusions It is proposed that the clinical courses should provide students with good experience,increase the deep learning engagement,and reform evaluation methods to improve the students' academic achievement.

Mammalian target of rapamycin (mTOR) is a serine/threonine protein kinase that is centrally involved in the control of cell growth, proliferation, differentiation and cell cycle regulation. Recent studies have found that the mTOR pathway is complicated and the dysregulation of mTOR pathway is recognized to be associated with lots of tumors. Several inhibitors of mTOR could inhibit oncogene transformation, growth and angiogenesis of tumors. So far, four inhibitors of mTOR have been tested in clinical trials, and some have been accessed to phase Ⅱ or Ⅲ trial. Therefore, in this review, we discuss the regulators that govern mTOR pathway activity, and highlight clinical results obtained with the first generation of mTOR inhibitors to reach the oncology clinics.

Observation on the effect of whole rice and whole wheat as sole food on the growth of young rats are furtherly made. The results showed that both whole rice and whole wheat showed no significant difference in the growth of young albino rats, but the difference between the rice group and rice plus leafy vegetable and egg group and that between the wheat group and wheat plus leafy vegetable and egg group are highly significant. Addition, of small amount of vegetable and egg alternatively as supplementary food significantly enhanced the nutritive value, in terms of growth effect, of both whole rice and whole wheat.

Objective To evaluate the effect of color Doppler ultrasound monitoring in artificial arteria-venous fistula in patients with uraemia.Methods 25 cases were examined with upper limbs arteriovenous fistulas with uremia and analysed by CDFI and 2D.The fistula and blood vessel was observe and hemodynamics changes were examined.Results Among 25 patients,18 cases showed good filling state of the vessel,3 cases with anastomoses stenosis,2cases with thrombus and 2cases with venous dilatations.Conclusion CDFI is an effective supplementary detective methods in treating hemodialysis patients with uremia.

Objective To explore the influence of ICAM-1 and LFA-1 on the breast cancer metastasis and provide scientific base for studying the molecular mechanism of breast cancer metastasis by observing the expression of ICAM-1(intercellular adhension molecule1) and LFA-1(Lymphocyte function related antigen 1) in different time different metastasis stage of breast cancer. Methods We observed the expression of ICAM-1 and LFA-1 in breast cancer tissue as well as the expression of ICAM-1、LFA-1 and VEGFR-3 in Lymphatic vessel endothelial cell of nearby the breast cancer tissues from the patients of the operation in the defferent stages with the methods of HE staining and immunohistochemistry staining. Results The positive rate of ICAM-1 and LFA-1 expression in cancer cell and cancer nest of breast cancer was increased gradually along with the increase of clinical stages and the occurrence of lymph node metastasis. And the positive rate of ICAM-1、LFA-1 and VEGFR-3 expression in lymphatic vessel endothelial cell of nearby the breast cancer tissues was increased gradually too along with the increase of clinical stages and the occurrence of lymph node metastasis,which has the positive correlation,and it has the positive correlation that the ICAM-1 and LFA-1 expressed in Lymphatic vessel endothelial cell of nearby the breast cancer tissues(P0.05).Conclusion The ICAM-1 and LFA-1 were related with breast cancer lymph metastasis,and the ICAM-1 and LFA-1 promoted breast cancer lymph metastasis through synergism each other.The increase or decrease of ICAM-1 and LFA-1 expression in the breast cancer tissue and lymphatic vessel endothelial cell of nearby the breast cancer tissues could as the data target to display certain instruction function for prevention and treatment of breast cancer lymph metastasis.The Lymphatic vessel quantity of nearby the breast cancer tissues was increased along with tumor progress, which may be related with breast cancer lymph metastasis.VEGFR-3 has the high specificity in the lymphatic vessel endothelial cell expression,and may act as the lymphatic vessel as the lymphatic vessel endothelial cell specific marker.

Objective To study the effects of the Chinese herbal compound (Erzhiwan, Shixiaosan and combined formula) on cholestasis-induced liver fibrosis rat’s uPA. Methods Bile duct ligation method was used to make the model of cholestasis-induced liver fibrosis. One week after the operation, the rats were randomly divided into five group (model group, UDCA group, Erzhiwan group, Shixiaosan group and hefang group). Each medicine intervention group was given corresponding medicine by intragastric administration. Sham and model group were given sodium chloride with equal dosage. At the end of 4th week, all rats were sacrificed and sampled. General state of health, hepatic function (ALT, AST, ALP, TBil) and pathological histology of hepatic tissue were recorded and measured. Results Compared with the sham group, the level of ALT, AST, ALP, TBil and the degree of liver fibrosis in model group were advanced significantly. Compared with model group, three Chinese herbal compound decreased serum level of ALP, ALT and AST (P
