Objective: To assess the tissue reactions of dogs to a new nanohydroxyapatite. Methods:Three dogs were used for root canal filling experiment, mandibular implanting and subcutaneous implanting experiment. AH-plus root canal sealer was used as control. The dogs were killed after implantation for 2,4 and 12 weeks separately. The tissue reaction was assessed by X-ray and light microscope examination. Results:①Root canal filling experiment: no inflammatory reaction was detected in specimens of n-HA group. In AH-plus group, implantation caused a middling inflammatory reaction after 2 weeks and 4 weeks. After 12 weeks the reaction of apical tissues was slight. ②Mandibular implanting experiment: no inflammatory reaction was showed by all n-HA groups and the group of AH-plus implanted for 12 weeks.Mild inflammatory reaction was observed in the groups of AH-plus implanted for 2 weeks and 4 weeks.③ Subcutaneous implanting experiment:after AH-plus was implanted for 2 weeks and 4 weeks, middling inflammatory reaction was observed. The group of n-HA implanted for 2 weeks showed the same reaction. No obvious inflammatory reaction was found in the other groups. Conclusion:n-HA shows better tissue compatibility than AH-plus.

Objectives To understand essential basis data availability for implementation of cost accounting in TCM hospitals. Methods Costs of a total of 1588 TCM hospitals were investigated by conducting the baseline survey via questionnaires in 2013. Results Departmental basic data (including ratio of office staff and entire staff, ratio of outpatient and inpatient departments in clinical department), and construction data for housing were well accessible, while utility fee and internal service data were not. Conclusion ①Public TCM hospitals need to improve and specify the basic cost data. ②Differences exit among different types and levels of hospitals in the availability of data. ③There are still difficulties in carrying out cost accounting in public TCM hospitals, which needs strong supports from all relevant departments.

Objective To explore the abnormally functional brain region in resting state in first-episode major depression disorder patients with function magnetic resonance imaging.Methods 51 patients diagnosed with first-episode major depression disorder according to DSM-Ⅳ and 50 gender-,age-,and education-matched healthy controls completed resting state fMRI scan.The severity of depression,and unpredicted homodynamic responses across the whole brain were analyzed using Hamilton depression scale,regional homogeneity and amplitude of low-frequency fluctuation,respectively.Results Compared with control group,the right medial frontal gyms (BA6,MNI:3,-3,63,K=34) and left medial frontal gyrus(BA9,MNI:-9,36,30,K=10) (P＜0.001,uncorrected) in the case group showed higher regional homogeneity,with statistical significance.Compared with control group,right medial frontal gyrus (BA6,MNI:3,-3,63,K =35) and right posterior cingulated gyrus (BA31,MNI:3,-36,36,K =11) (P＜ 0.001,uncorrected)in the case group showed higher amplitude of low-frequency fluctuation,with statistical significance.Conclusion First-episode major depression disorder patients in resting state had several abnormally functional brain regions,which might be related to the pathological mechanism of depression disorder.
