Objective To explore the application effect of home care on the basis of temperament combined with social competence in preschool children with bronchial asthma.Methods A total of 100 preschool children outpatients with bronchial asthma who came to our hospital from January 1 to February 28,2013 were selected with the method of convenience sampling and were randomly divided into observed group and control group with 50 cases in each group.Cases of the observed group were divided into ordinary,middle,and strengthen subgroups according to temperament and social competence.The control group and the ordinary subgroup received routine care interventions,and the other subgroups were given corresponding enhanced care measures.The attack rate of asthma,medical care,quality of life and lung function during one year follow-up were observed and compared between the two groups.Results Within the first six months of follow-up,patients in observed group got better control in acute attacks than the control group [(2.3±0.4) times vs.(3.4±0.3) times,x2=5.710,P＜0.05)].The percentage of forced expiratory volume in the first second and Pediatric Asthma Quality of Life Questionnaire scores in observed group were significantly higher than the control group one years later [(86.9±4.6)％ vs.(85.5±3.8)％ and (90.1±7.5) vs.(76.5±8.0),P＜0.05].Conclusions The application of temperament type combined with social competence showed a good practical value in home care for asthma preschoolers.

Objective To investigate the effectiveness of hyperthermia of different degrees in killing tumor cells and its influence on Na+ -K+ -ATPase activities in erythrocytes. Methods Cultured low differentiated stomach gland tumor cells (SGC-170) and large intestine gland tumor cells (LOVO) (1?106?ml-1 each) were mixed with concentrated RBCs respectively and incubated in warm bath of 37℃ , 42℃, 43℃ , 45℃ or 47℃ for 40 min respectively. After hyperthermic treatment tumor cells were isolated from RBCs using density gradient centrifugation and the live tumor cells were counted by typan staining. The isolated tumor cells were then cultured and the clone formation of tumor cells was checked. The cultured tumor cells were marked with 5-bromo deoxyuridine and DNA metabolism was examined. The Na+ -K+ -ATPase activities in RBC after hyperthermic treatment were also determined. Results The amount of tumor cells was significantly decreased by 40 min hyperthermic treatment in a temperature-dependent manner from 42-471 as compared with the control group (37℃) (P

This study was aimed to discuss the ways of converting clinical data entered in the Case Report Form (CRF) to Study Data Tabulation Model (SDTM) database format in clinical research of traditional Chinese medicine (TCM). Currently, there were three approaches for implementing SDTM, which were the pure SDTM approach, submission-only approach and database-only approach. This article compared and analyzed advantages and disadvantages of three approaches and introduced experiences of the Clinical Evaluation Center of China Academy of Chinese Medical Sciences using database-only approach for SDTM implementation. The results showed that pure SDTM approach can maximally embrace SDTM standards. However, the current process and software system should be modified. Therefore, it was time-consuming and expensive. The submission-only approach was the most economic way in the application of SDTM standards. However, the data quality and traceability may not be guaranteed. The database-only approach built the study database based on the SDTM standard by writing transformed program before data entry while the data collection system was not SDTM-compatible. It was concluded that database-only approach for implementation SDTM was a suitable and practical way to TCM clinical research.

Background and purpose:Cancer microenvironment has become a hot topic of cancer research. It is important in the initiation of colorectal cancer. This study aimed to discuss the correlation between the characteristics of tissue culturein vitro and different cell types in cancer microenvironment.Methods:Samples were collected at different distances from the colorectal cancer lesions, which were named as positions 1, 2 and 3 from distal to proximal. Tissues were cut into 1-2 mm3 forin vitro culturing. HE staining was used to observe the structure of crypts. Immunohistochemistry was used to detect the expressions of Cyclin D1 (CD1), CD133, cytokeratin18 (CK18), vimentin and α-smooth muscle actin (α-SMA).Results:Position 3 grew faster than position 2 and position 1. As getting closer to the colorectal cancer lesions, expressions of CD1, CD133, vimentin and α-SMA were increased while expression of CK18 was decreased.Conclusion:The tissue structure and the expression of different cell types in cancer microenvironment changed more seriously as get-ting closer to the colorectal cancer lesions. This indicated that the change of cancer microenvironment may contribute to the initiation of colorectal cancer.
