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.

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%.

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. The top five frequently-used medicine were Rhizoma Acori Tatarinowii, Radix Polygalae, Rhizoma Ligustici Chuanxiong, Radix Salviae Miltiorrhizae, and Radix Angelicae Sinensis. The top five frequently-used drug pairs of homologous Chinese medicine of medicine and food were Rhizoma Dioscoreae→Poria, Poria→Pericarpium Citri Reticulatae, Rhizoma Dioscoreae→Fructus Lycii, Fructus Lycii→Fructus Alpiniae Oxyphyllae, and Fructus Lycii→Poria. The top five frequently-used drug pairs were Rhizoma Acori Tatarinowii→Radix Polygalae, Radix Salviae Miltiorrhizae→Rhizoma Acori Tatarinowii, Rhizoma Ligustici Chuanxiong→Rhizoma Acori Tatarinowii, Radix Salviae Miltiorrhizae→Rhizoma Ligustici Chuanxiong, and Rhizoma Acori Tatarinowii→Radix Astragali Seu Hedysari.

Objective To evaluate a new type of endoloop for closure of full-thickness gastric defects left by EFR.Methods A total of 32 patients who underwent EFR at our hospital between October 2014 and February 2015 with gastric fundus submucosal tumors were retrospectively analyzed.After the resection,LeCampTM endoloops and Olympus endoloops were used respectively to close the gastric defect in the study group (n =14) and the control group(n =18).The closure success rates,closure time,complications and the healing rates were compared.Results All lesions were removed by using EFR technique.The closure success rates of the two groups were both 100％.The closure time were 13.86 ± 4.62 minutes and 18.28 ± 6.48 minutes in study group and control group respectively with significant difference (P ＜ 0.05).9.43 ±4.09 metallic clips and 1.00 ±0.00 endoloops were used in study group and 9.67 ± 3.61 metallic clips and 1.06 ± 0.24 endoloops were used in control group (P ＞ 0.05).One patient in study group and 2 patients in control group received abdominal puncture for relieving the pneumoperitoneum during the operation (P ＞ 0.05).No complications such as subcutaneous emphysema,pneumothorax,pneumomediastinum,delayed bleeding,or abdominal infection were found after the operations in either group.The wounds healed in all patients in 2 months after the procedure.Conclusion The use of novel endoloop and metallic clips is a relatively safe,easy,and feasible method for repairing large gastric post-EFR defects,which is of good clinical application value.

Objective To observe the safety of midazolam and fentanyl in coronary intervention and its effect on haemodynamics. Methods 150 cases undergoing coronary intervention were randomly divided into three groups(n=50 for each):the control group were given injection of 5 ml saline,midazolam group were given 0.04 mg/kg midazolam and combined fentanyl group were given injection of 0.02 mg/kg midazolam with 1.2μg/kg fent-anyl intravenously. Heart rate(HR),mean blood pressure(MAP),SpO<,2>,OAA/S and BIS were observed during the intervention and the patients' satisfaction and the incidence of complications were investigated. Results There was no significant difference among the three groups in MAP and HR (F=3.34,2.98,P>0.05). MAP increased from (95.7±14.5) mm Hg to (85.4±15.3) mm Hg after treatment (t=4.34,P<0.01) and HR increased from (83.3±23.4) times/min to (78.4±22.7) times/min in control group (t=3.37,P<0.01). BIS score was (90.5±7.2),(75.5±12.8) and (72.3±14.1) during intervention and 24 hVAS score was (53.5±25.4),(58.8±18.2) and (71.9±16.8) in control group,midazolam group and combined fentanyl group,with significant difference between groups (F=10.89,8.56,P<0.01). Conclusion Low dose of midazolam and fentanyl can make the patients calm,which relieves the tensity and anxiety and enhance the tolerance and safety of intervention but has no remarkable effect on bemodynamics.
