ABSTRACT
ObjectiveTo investigate the immunological improvement effects of different doses of ursodeoxycholic acid (UDCA) on patients with different stages of primary biliary cirrhosis (PBC) and enhance the understanding of the roles of the immune system in the disease, and to provide evidence for the standardized clinical treatment of PBC. MethodsOne hundred and eighty patients with PBC who were admitted to our hospital from March 2012 to Janurary 2014 were enrolled and equally divided into three classes according to the stage of PBC: early stage, cirrhotic stage, and poor biochemical response stage. Patients in each class were equally divided into three groups according to the dose of UDCA: 8-10, 13-15, and 20-25 mg·kg-1·d-1. The general information, clinical symptoms, biochemical indices, and changes in T lymphocyte subsets and cytokines in peripheral blood after the treatment with different doses of UDCA were analyzed. Comparison of continuous data was performed by t test, and comparison of categorical data was performed by χ2 test. ResultsIn patients with early-stage PBC who were treated with 13-15 mg·kg-1·d-1 UDCA, the percentage of CD3+CD4+ T cells, CD4+/CD8+ ratio, and expression of interferon-gamma were significantly reduced after treatment (54.8%±11.6% vs 34.7%±7.7 %, t=6.5, P＜0.05; 2.3±1.0 vs 1.6±0.6, t=2.7, P＜0.05; 33.0±12.3 vs 23.7±7.2 ng/L, t=2.9, P＜0.05), while the secretion of interleukin-4 was significantly increased after treatment (29.0±4.6 vs 38.5±7.1 ng/L, t=5.0, P＜0.05). ConclusionThe UDCA with a dose of 13-15 mg·kg-1·d-1 can substantially improve the immune status in patients with early-stage PBC. The application of UDCA should be standardized in order to achieve the desired response.
ABSTRACT
Aiming at the existing problems in the teaching hospital,teachers and practical students during clinical practice teaching,we explored actively in talent training and teaching base construction and promoted the improvement of clinical practice ability for medical students.
ABSTRACT
Objective: To develop a bar code method for the medical record management under the voluntarily established software of medical record management and retrieval system.Method: The software of medical record management system and bar code as well as the necessary processing,management and application system were established.Results: With the development of information technology and the bar code technology mature application,the bar code automatic diagnosis technology was applied to the medical record management process including recycling,cataloging,reorganization,arrangement,storage,pigeonhole,the top carriage,the bottom carriage,circulation and return,which could enhance the data acquisition and information processing speed,guarantee the accurate rate in the movement link,raise the hospital management level,and provide detailed,accurate and timely data for the hospital superintendent.Conclusion: The research on the software system of medical record management and the bar code application can enhance the hospital medical record utility and reduce the medical record administrative personnel's working pressure.The software of medical record management system and bar code are practical and effective in medical record management.
