Traditional Chinese Medicine Informatics is a new branch created by integration of Traditional Chinese Medicine and Information Science.To research the connotation and principle of TCM Informatics will enrich the theory and promote the development of disciplines.This article thoroughly discussed the theoretical foundation and discipline characters of TCM Informatics.Then it discussed the principle and tasks from TCM information formation,acquisition,identification,transformation,feedback control,activation and dissemination of experiential knowledge.

Objective:To compare the shear bond strength of dentin to composite resin in different post-treatment time period after tooth bleaching with the TREE dental whitening gel and observe the dentin/composite interface of each group. Methods:Eighteen intact premolars were randomly divided into 3 groups(n=6):A:The specimens were immersed into artificial saliva for 3 weeks then adhesion without bleaching; B:Adhesion immediately after bleaching for 3 weeks,during bleaching the specimens were immersed into artificial saliva; C:Before adhesion the specimens immersed in artificial saliva for further 2 weeks after bleaching for 3 weeks. Five specimens from each group were randomly submitted to shear bond strength test. The specimen remained in each group were sectioned to be observed by the scanning electron microscope.Results:(1)The shear bond strength of the group B (10.74?3.03) MPa was significantly lower than that of the group A (18.61?3.56) MPa or the group C (17.21?3.15) MPa (P0.05); (2)The resin tags present in the dentin/composite interface was scarce for the group B,and that were shorter than the group A; The resin tags of the group A and group C were similar in number,but that of the group C was shorter than that of the group A. Conclusion:The use of TREE whitening gel immediately before bonding significantly reduces bond strength,but immersion of bleached teeth in artificial saliva for 2 weeks before bonding results in a return to control bond strength.

Objective To investigate the level of professional commitment of nursing baccalaureate students,and explore the relationship between the professional commitment and communication ability.Methods Questionnaires were used to investigate 430 nursing baccalaureate students who were studying in the school.Results The professional commitment of nursing students was in the middle level.Correlation analysis revealed that the communication ability was correlated with the professional commitment.Conclusions We should take measures to improve the competency of professional commitment of nursing undergraduate students,strengthen their communication ability,promote the construction of nursing staff.

Objective To investigate the new method of ureter bladder anastomosis in renal transplantation.Methods The ureter was pulled into bladder for 1.2 cm through tunnel at the lateral- top of bladder wall,and the ureter fixed on the bladder wall by 2-3 acus with catgut suture.Results Forty of 42 patients had no complications,and recovered very well,except for 1 cases of necrosis caused by acute rejection and 1 case on urine leakage caused by catheter obstruction from blood clot.Conclu- sion This method is simple,easy to operate,safe and reliable with less complications.

Objective:To detect the level of immune related cytokines in the serum of the patient with Parkinson’s Disease (PD) and to explore the influencing factors of the cytokines.Methods:51 patients with PD (PD group) and 35 healthy control (control group) were studied.The two groups were detected the serum concentration of IL-1?,IL-2,IL-6 and TNF-? by the way of radio immunity.Results:The serum level of IL-6 and TNF-? in the PD group is significantly higher than that of the control group (P

Objective To study the influencing elements in x-Gal staining method and optimize the reactive conditions so that nonspecific background can be eliminated and grafted exogenous cells carrying LacZ gene can be discerned correctly. Methods C17 2 cells (carrying lzcZ gene) were injected into the right lateral ventricle both in the adult and newborn animals. After one week they were perfused using two methods, then the slices were stained at different pH and incubating time respectively. The X-gal positive cells in hippocampus were counted under light microscope. Results Background staining in this method has close correlation with the species and age of the host animals and it decreases when pH is higher or incubating time is shorter. The results are the best when pH 9 5 and the incubating time is 1*!h.Conclusion The reliability of X-gal staining method depends on optimization of several parameters, including pH, incubating time, perfusion etc. It is necessary to establish the correspondent controls.;

Objective: To explore the clinical significance of combination preoperative carbohydrate loading and postoperative enteral nutrition in patients with gastric cancer during perioperative period. Methods: 70 patients were randomly divided into group A(preoperative fasting + postoperative EN,n = 23),group B(preoperative carbohydrate loading + postoperative TPN,n = 23) and group C(preoperative carbohydrate loading + postoperative EN,n = 20).After operation,insulin sensitivity,nutritional status,immune function and clinical outcome were compared among three groups. Results: Compared with the other two groups in insulin sensitivity,nutritional status,immune function and clinical outcome,the group C was better and different(P

Objective By studying the prescriptions and medicines for treating rheumatoid arthritis (RA) prescribed by modem doctors, we tried to provide new ideas for developing the new medicines for treating rheumatoid arthritis. Methods 340 prescriptions on treating rheumatoid arthritis were collected from core medical periodicals and books published in the recent 20 years. Make a statistical analysis to the medicines in these prescriptions according to TCM etiological and pharmaceutical theories and modern researching foundlings. Results Among all 254 Chinese medicines used for treating RA, 32 medicines belong to worm and vine medicines, being used for 806 times. Conclusion The worm and vine medicines are frequently used in treating RA with good therapeutic effects combined with other kinds of medicines.
