Under the impact of medical and health system reform and focal events in China, the medical vio-lence policy change is characterized by partial discontinuous equilibrium. It gradually evolves from policymaker-based discontinuity to participatory one, from single decision-making field to the collaborative one, and from the ex-cessive protection of unilateral interest to the maintenance of public interest as a core. In the future, if we want to re-alize the effective minimization of medical violence by public policy, the participation of all parties in the policy deci-sion should be strengthened, the focal events should be analyzed as policy issues, and the policy should be clear in order to overcome the negative influence of the inactivity of old policies.

Objective To mine the relation between leukemia and genes using Weka. Methods The papers on leuke-mia and genes were retrieved from PubMed, their subject headings and subheadings were extracted using BICOMB to generate co-occurrence matrix and term-paper matrix. The research hotspots were found by cluster analysis of the data on co-occurrence matrix using Weka and Cobweb. The literature was verified. Results The 42 high fre-quency words were clustered into 7 classes by Weka. No high frequency words of leukemia or genes were found in classes 1, 2, 4 and 5, indicating that their clustering efficiency was poor. The clustering efficiency of the other 3 classes was good. Conclusion Cluster analysis showed that leukemia is related with myc gene, ab1 gene, p53 gene, virus gene, immunoglobulin gene and mdm gene.

All of the results except 11 cases were compared with pathological diagnosis. Results The accuracy of electronic gastroscopy, EUS and CTVE on the diagnosis of the protuberant lesions of the upper gastrointestinal tract were 16.7% ,89. 6% ,66. 7% , respectively . There was a significantly difference among them (P

Objective To estimate the fatality rate of SARS so as to provide data for the evaluation of patient care. Methods Based on the clinical features of the death cases of SARS, the average period between the time of clinical diagnosis and the time of death was determined and a method of estimation, which was lagged in time, was thus developed. Differences in the fatality rates of SARS across the world as well as the patterns of the differences were discussed using Chi-square and trend Chi-square tests. Results The fatality rate of SARS in Beijing, which presented a progressively downward tendency, was 7.2% by June 5, 2003, ranking relatively high among the SARS-hit zones in China. Conclusion Certain achievements have been attained in the clinical treatment of SARS cases, and yet more efforts need to be exerted. It is estimated that the eventual fatality rate of SARS in Beijing will be around 8%.

This paper summarized that the treatments of nourishing lung yin and Tonifying Qi, promoting blood circulation and removing blood stasis and the method of Chinese medicine iontophoresis could work on lung function of the patients with idiopathic pulmonary fibrosis. The review suggested that traditional Chinese medicine compound for treating pulmonary fibrosis mainly by Nourishing Yin, Qi and promoting blood circulation. In the treatment of IPF, the combination of traditional Chinese medicine and Western medicine showed more benefit than western medicine treatment alone.

Objective To analyze the compatibility laws of homologous Chinese medicine of medicine and food in prevention and treatment of Alzheimer disease (AD). Methods We screened the clinical literature for the treatment of AD during 1988-2012 in TCM Clinical Diagnosis and Treatment Database, CNKI, VIP and Wanfang database. The nature, flavor, channel tropism, high frequency drug pair and compatibility laws of Chinese medicine and homologous Chinese medicine of medicine and food in prevention and treatment of AD were analyzed by frequency statistics and association rules. Results Two hundred and twenty-two clinical literatures were included. The top five frequently-used homologous Chinese medicines of medicine and food were Poria, Fructus Lycii, Fructus Alpiniae Oxyphyllae, Semen Persicae, and Rhizoma Dioscoreae.
