Objective To discuss cultivation of higher vocational nursing talents in the model of learning and working rotation during the cooperation of school and hospital. Methods Students were cultivated by two years school study, two years learning and hospital work rotation and one year hospital position practice which was adopted as an "221" mode by means of organizational leadership,agreed safeguard and co-management. Half day learning and half day practice in four learning situation which have been transformed from the real professional workplace. Results Scores of professional core courses and operation skills had been improved significantly; Students cultivated by "221" mode had more superiority on the aspects of post adaptability, hand skills, communication skills and the ability of linking theory to practice. Conclusions The model of learning and working rotation during the cooperation of school and hospital is the important way of cultivating higher vocational nursing talents.

Objective:To establish an ICP-MS method to determine the contents, extraction and migration of Mg and Al in poly-propylene infusion bottles. Methods:An ignition pretreatment method was adopted to determine the contents of Mg and Al in the mate-rials. Five different extraction media with extreme extraction were used to extract and test Mg and Al in polypropylene infusion bottles. Three injections commonly used in clinics were put into polypropylene infusion bottles to carry out accelerated experiment, and the con-tents of Mg and Al were determined by ICP-MS. Results:Mg and Al both had a good linear relationship within the range of 0. 025-1. 0μg·ml-1 (r =0.999 8 and 0.999 0). The recoveries for polypropylene infusion bottles and extraction and migration test were 93. 77%-105. 0% and 96. 53%-103. 89% with RSD of 0. 4%-6. 9% and 1. 0%-7. 1%(n=9), respectively. Conclusion:The meth-od is accurate, sensitive and simple, which can provide reference for the safety data of polypropylene infusion bottles.

Oral imaging techniques have been widely and increasingly used in clinical practice.This article reviews the functions,characteristics and principles of three kinds of oral imaging instruments including panoramic x-ray unit,intraoral x-ray unit and stomatology endoscope.

Objective To detecte the pathogenetic mechanism of cortical deficit in persons with strabismic amblyopia by blood oxygenation level dependent-functional magnetic resonance imaging (BOLD-fMRI). Methods The data of BOLD-fMRI of occipital visual cortex in 11 persons with strabismic amblyopia and 8 healthy ones were collected by 1.5T MRI system. The results of binocular pixel exponent in strabismic amblyopia group was compared with that in the normal group and the result of and average activation of cortical neuron in strabismic amblyopia group was analyzed. Results The binocular pixel exponent was lower in the strabismic amblyopia group (14.13%?4.55%) than that in the normal group(47.82%?5.34%) ( P

As the development of hospital information systems in the third-tier hospitals of the first grade in China gradually deepens, there has appeared an urgent need to formulate standards for the management of such systems. The paper offers proposals for the structure, composition and main responsibilities of the centers for hospital information management, posts setting and post responsibilities in the centers, the number of allocated personnel in the centers and the number of personnel required for various posts, and management standards and operating procedures in the centers.

ObjectiveTo investigate the action mechanism of CD20 lymphocyte infiltration in the renal allograft biopsy with chronic allograft nephropathy (CAN).MethodsCAN cases confirmed by renal biopsy within 2 years after renal transplantation served as study subjects. By using immunohistochemistry,the deposition of C4d and the CD20-positive lymphocytes infiltration in the renal grafts were examined.The clinical follow-up data were analyzed.ResultsForty-four cases of CAN were enrolled in the study, including 13 cases (29.5％ ) of CD20-positive lymphocytes infiltration,and 31cases (70.5％ )of CD20-negative lymphocytes infiltration. CD20-positive lymphocytes in biopsy showed nodular and scattered lymphocytes infiltration.There were 5 (26.3％)cases of CAN Ⅰ,4 cases (25.0％) of CAN Ⅱ,and 4 (44.4％) of CAN Ⅲ in CD20-positive group.There was no statistically significant difference between the only CAN group and CAN with AR group in CD20-positive rate.Immunohistochemical staining showed there were 12 cases (27.3％) with C4d linear deposition in peritubular capillary endothelial cells (PTC).C4d positive rate had no significant difference among the CAN classifications. There was no significant relationship between C4d deposition and CD20-positive lymphocytic infiltration.The average serum creatinine in CD20-negtive group and CD20-posigtive group was 140.8 ± 22.0 and 183.5 ± 25.5μmol/L before biopsy,and 165.6 ± 37.6 and 242.2 ± 59.1 μmol/L one year after biopsy.The average serum creatinine level in CD20-positive group was higher than in CD20-negtive group before and after biopsy.ConclusionProgressive chronic humoral immunity is high risk in the process of CAN. The CD20-positive lymphocyte infiltration has no relevance with CAN grade and C4d deposition in PTC,but is associated with circulating antibody PRA and allograft long-term outcome. Pathogenetic mechanism may not contribute to chronic humoral immune,but B cells presenting donor antigens,are recognized and activated by T cells as antigen-presenting cells.

ObjectiveTo investigate the prognostic factors of non-small cell lung cancer (NSCLC) after resection.MethodsClinical data of 131 NSCLC patients who underwent resection were reviewed and divided into chemotherapy group(86 cases) and non-chemotherapy group(45 cases) according to the treatment method.Survival rate was calculated by Kaplan-Meier method.The prognosis was analyzed by Cox proportional hazards model.ResultsThe median survival time (MST) of squamous cell carcinoma (76 cases),bronchial alveolar cell carcinoma( 8 cases),adenocarcinoma( 35 cases ),adenosquamous carcinoma (12 cases) was 60,54,34,24 months respectively (P＜0.05).For the patients of stage Ⅰ B,the MST of chemotherapy group and non-chemotherapy group was 75 and 76 months respectively(P ＞ 0.05 ).Multivariate analysis showed that tumor size,T stage,N stage,chemotherapy were independent prognostic factors (P =0.080,0.002,0.000,0.029).Conclusions Squamous cell carcinoma and bronchial alveolar cell carcinoma have better prognosis than adenocarcinoma,adenosquamous carcinoma.For the patients of stage Ⅰ B,the survival time can't be prolonged through platinum-based chemotherapy.Tumor size,T stage,N stage,chemotherapy are independent prognostic factors.
