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 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 impact of the different antiepileptic drugs on cognitive function in patients with epilepsy.Methods There are 280 cases of patients with epilepsy from Department of Neurology in our hospital out-patient and hospitalization, while 32 cases are the normal control group. The patients were randomly divided into groups of topiramate, carbamazepine and sodium valproate group and topiramate plus valproate combined therapy group. Wechsler Memory Scale was used by the patients before and after treatment to assess cognitive function, and compared with the normal group. Results Carbamazepine monotherapy group and the valproate group were no significant difference in areas of cognitive function belong to the normal level; Topiramate monotherapy group cognitive function was significantly lower than normal, the joint drug group was the most of the lower level of cognitive function. Conclusion Carbamazepine and valproate monotherapy were applied had the minor cognitive impairment, combination therapy of epilepsy in patients had severe cognitive impairment.

Objective To observe the effects of the home tele-rehabilitation guidance on activities of daily living and motor function in patients after cerebral infarction. Methods 101 cases with cerebral infarction at recovery stage were divided into control (n=50) and rehabilitation (n=51) group. The rehabilitation group received home tele-rehabilitation guidance. They were assessed with the Barthel index (BI) and the simplified Fugl-Meyer assessment (FMA) before and 3 month after treatment. Results There is no significant difference in both the BI and FMA between these groups before treatment, and the rehabilitation group improved more after treatment (P<0.05). ConclusionHome tele-rehabilitation guidance can facilitate the recovery of activities of daily living and motor function in cerebral infarction patients.

ObjectiveTo observe the effect of bionics pulsed electromagnetic fields (BEMF) on the biomechanical property of ovariectomized Wistar rats.MethodsForty 6 month old female Wistar rats were randomly divided into four different groups: ovariectomy group (group A), sham operation group (group B), BEMF+ovariectomized group (group C) and estrogen+ovariectomized group (group D). All rats were subjected to bilateral ovariectomy except group B. 8 weeks after operation, rats of group D were given estrogen 0.5 mg/kg/2 w. Rats of group C were exposed to BEMF, 1 h /d. Rats of group A and B were given nothing as control groups. All treatments was being kept for 10 weeks. After treatments finished, measuring the biomechanical property of femur and lumbar spine.ResultsThere were significant differences in the biomechanical property between group D and group A, and group C and group A (P<0.05).ConclusionBEMF can improve the biomechanical property of ovariectomized Wistar rats significantly and increase the capability of resisting fracture significantly.

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.
