Chinese Journal of Hospital Administration 2008;24(4):239-241
The goal of hospital information system construction is to establish a comprehensive,safe and stable information network.A new or relocated hospital is redesigned and has overall layout,which facilitates achieving the objective of information system construction.The authors introduce the architecture and construction of information network in the process of hospitaI relocation.The important points of information coverage at different functional areas are determined,including the key business area,non-key business area,server area,radiological area,and other functional areas,which may improve the effectiveness of the investment.At the same time,the possibility of large area information system paralysis due to network fault is minimized to ensure the security of information system.
3.Influence of self nursing education on the therapeutic compliance and life quality of patients with infectious tuberculosis
Chinese Journal of Practical Nursing 2008;24(18):16-18
Objective We discussed the application and clinical effect of serf nursing education in patients with infectious tuberculosis. Methods We divided 140 patients with infectious tuberculosis into the test group and the control group with 70 cases in each group. The control group adopted health education. The test group received individual and selective self nursing education, including serf mastering of tuberculosis, self monitoring of illness, completion of ther therapeutic process by oneself, serf management of diet, self regulation andf control of motion and education of self nursing technique. The intervention continued for 3 months. Pulmonary tuberculosis specific knowledge inventory, therapeutic compliance investigation inventory and general questionnaire on living (GQOL) were adopted in the two groups and the results were compared. Results The therapeutic compliance and life quality of the test group were evidently higher than those of the control group after self nursing education (P<0.01). The mastering of tuberculosis knowledge of the test group was also superior than that of the control group (P<0.01). Conclusions Self nursing education could increase the therapeutic compliance as well as the life quality of patients.
4.Clinical research of the self-made subcutaneous negative pressure drainage tube to prevent postoperative incision infection of elderly patients with obstructive colorectal cancer
Chinese Journal of Postgraduates of Medicine 2009;32(32):14-16
Objective To investigate the means which can prevent postoperative incision infection of elderly patients with obstructive colorectal cancer. Methods Sixty-seven cases of elderly patients with obstructive colorectal cancer adopting surgical treatment were divided into two groups, including experimental group with 37 cases and control group with 30 cases. Put self-made negative pressure drainage tube with side-hole into subcutaneous interspace of abdominal incision of experimental group alter operation, kept continuous negative pressure drainage 7-10 d and pull out the self-made subcutaneous negative pressure drainage tubes till drainage volume decreased obviously. The abdominal wall incisions of the control group were given conventional suture. Results Incision infection occurred in only one case (2.7%) and no incision dehiscence occurred in the experimental group, and incision healing time was (9.36 ± 2.18) d. Incision infection occurred in 7 cases (23.3%) in the control group, of which there were 3 cases (10.0%) of wound dehiscence, incision healing time was (12.25 ±4.06) d. Incision infection rate of the two groups had significant difference (χ2= 6.706,P < 0.05), incision dehiscence rate of the two groups had no significant difference (P 0.05), incision healing time of the two groups had significant difference (t = 6.676, P < 0.05). Conclusion Using the self-made subcutaneous negative pressure drainage tube and keeping it continuous negative pressure drainage after operation can be effective in preventing incision infection of elderly patients with obstructive colorectal cancer, and promote wound healing.
5.Analysis On issues of academic standard in cover letters from affliated medical institutes of university
Chinese Journal of Medical Science Research Management 2008;21(5):266-268
The cover letters from 123 affiliated medical institutes in 57 Universities were selected.The departments giving cover letters or signing and the contents of academic standard in the cover letters were summarized and analyzed. It found that the departments were not unified and the contents of the academic standard were little. The same standard was deficient about violation of the academic standard in manuscripts. In this paper it was proposed that the Universities should make standard for the cover letters from their affiliated medical institutes. It could decrease the violation of the academic standard.
6.Spectral Reconstruction and Quantitative Analysis by B-Spline Transformations and Penalized Partial Least Squares Approach
Chinese Journal of Analytical Chemistry 2009;37(12):1820-1824
Taking into account the near infrared spectra(NIR) on numerous predictor variables with serious collinearity and having nonlinear quantitative relationship with the chemical compositions, a novel nonlinear partial least squares(PLS) approach, termed as Spline-PPLS, was constructed by combining the penalized partial least squares(PPLS) regression with B-splines transformation. Firstly, the observed spectral predictors were considered as discrete observations of curves of the wavelength and were nonlinearly transformed using B-spline basis functions. The choice of the degree of the polynomial pieces and of the number of knots was performed using the cross-validation strategy. Then, the PPLS algorithm was performed on the high dimensional transformed data matrix to build the calibration model by imposing a penalty term to the optimization criterion of PLS. The roughness penalty term indeed controlled the curvature of the functions and its smoothing parameter could also be obtained by the cross-validation. Finally, the proposed Spline-PPLS approach was applied to the wheat NIR diffuse reflectance spectra reconstruction and quantitative analysis. The result indicates that the Spline-PPLS approach not only can yield high accuracy reconstructing spectrum, but also improves the model prediction accuracy in the case of nonlinear relationships.
8.SELECTIVE TOXICITY OF RHODAMINE 123 ON CARCINOMA CELL IN VITRO
Acta Anatomica Sinica 1953;0(01):-
The selective toxicity of the mitochondria-specific cationic fluorescent dye rhodamine 123 (Rh-123) on HeLa cells in culture was studied. In this report, we demonstrate that with continuous exposure, Rh-123 markedly inhibited the growth of HeLa cells but had little effect on normal human kidney fibroblasts. With continuously exposed to Rh-123, the growth rate, colony forming ability, and mitotic index of HeLa cells were decreased. The mechanism of toxicity of Rh-123 on HeLa ceils was investigated by EM and enzyme cytochemistry stain. The mitochondria of carcinoma cells were the main targets for the inhibitory action of Rh-123, since they selectively accumulated the dye. At the dosage of Rh-123 which was toxic to HeLa cells, the structure and function of mitochondria were disrupted, as the mitochondriarelated enzymes, i. e., ATPase, LDH, and SDH were inhibited. The possible mechanism of the action of Rh-123 on HeLa cells is briefly discussed.
