Health care policy should follow principles of total efficiency, no-harm, fairness and justice as ethi-cal standards for public policy. Diagnosis Related Groups( DRGs) as a sign of new health care reform ( NHCR) is implemented as a pilot program across the country, with the obvious function of suppressing excessive growth in medi-cal costs and over-treatment. From the dimension of ethical values, the DRGs has avoided unethical individuals, fol-lowed the principle of total efficiency and achieved the equalization of social security. However it has also increased ethical risks and been adverse to the development of medical research. To realize the reasonable development of DRGS, the construction of DRGs must be improved, and security policies must be reasonable and feasible; orderly measures must be established to ensure promotion and implementation;the government’s financial investment must be increased to protect the social welfare of public hospitals;a sound communication mechanism must be implemented, and interaction between medical institutions and insurance institutions must be strengthened.

Objective To understand the related situations of employee's emotional management ability and work ability. Methods 180 employees from an automobile manufacturing company in Hefei were selected and surveyed. Results The mean score of employee's emotional management was 102.50. Mean score of employees work ability was 39.64, of all the work ability index, the physical and mental ability to work got the highest score; the work ability index about the psychological state of work and life was lower. Employee's emotion management ability and work ability was not significantly different between different genders. Conclusions There is significant correlation between employee's emotion management and work ability.

Objective To investigate the effects of L-carnitine(L-CN)on electrophysiological changes induced by atrial ischemia in dogs.Methods Twelve dogs were divided into normal saline(NS)group and L-CN group.Atrial ischemia was induced by ligation of an atrial arterial branch of right coronary artery.Atrial effective refractory period(AERP)and conduction velocity(CV)of right atrium were measured before and after 3 hour's coronary artery ligation.Atrial wavelength(WL)and inducibility of atrial fibrillation(AF)were calculated.Histological examination was performed.Results (1)AERP and WL shortened dramatically after ligation of coronary artery in NS group;they showed no remarkable change in L-CN group.(2)There was no significant change of CV in the two groups.(3)AF was induced in 0 of 12 dogs under basic condition.(3)After ligation of the right coronary artery,AF was induced in all of the 6 dogs in NS group and 0 of 6 dogs in L-CN group.(5)Histological examination revealed that the ischemic changes occurred only in NS group.Conclusion Electrophysiological changes induced by atrial ischemia could be prevented by infusion of L-CN.

Objectives To evaluate the safety of intravenous amiodarone in patients with atrial fibrillation and rapid ventricular response via an accessory pathway. Methods Sixteen patients with Wolff Parkinson White syndrome (W P W group) and 16 patients with concealed accessory pathway (control group) were included. The anterograde effective refractory period of accessory pathway (ERP AP ) in W P W group and the effective refractory period of atrioventricular node (ERP AVN ) in control group were measured. Then 150mg of amiodarone was injected intravenously in 10min, the ERP AP and ERP AVN were remeasured 10min later. Results After amiodarone injection, ERP AP was increased slightly ( P

AIM: To determine the effect of exogenous phosphocreatine (PCr) at different concentrations on transient outward potassium (Ito) current in rat ischemic ventricular mid-myocardial (M) cells and to explore the antiarrhythmia mechanism in the treatment of ischemic heart disease. METHODS: M cells were isolated enzymatically from left ventricular mid-myocardium of rats. Peak Ito current was recorded by patch-clamp technique in the whole-cell configuration when M cells were superfused with normal Tyrode solution,simple ischemic solution,and simulated ischemic solution containing PCr at concentrations of 5,10,20 and 30 mmol/L for 10 min. RESULTS: Peak Ito current density of M cells superfused with simple simulated ischemic solution was significantly reduced by (76.1±6.3)% (P<0.05) compared with M cells superfused with Tyrode solution. Ischemic solution containing 5,10,20 and 30 mmol/L PCr reduced peak Ito current density by (57.1±9.6)% (P<0.05),(40.3±10.3)% (P<0.05),(34.3±9.6)% (P<0.05) and (32.1±10.6)% (P<0.05),respectively. There was statistical difference among ischemic solution without PCr and containing PCr at concentrations of 5 and 10 mmol/L groups (P<0.05). No statistical difference among groups of 10,20 and 30 mmol/L PCr was observed (P>0.05). CONCLUSION: PCr reverses the inhibition of Ito current under ischemic condition in M cells,which may be the mechanism responsible for arrhythmia prevention in ischemic heart disease. PCr at concentrations of 0～10 mmol/L exerts significant dose-effect relationship.

Objective To study the mechanism of arachnoidal fibrosis after subarachnoid hemor- rhage. Methods Rats were divided into control group, experiment group and treatment group. Radioim- munoassay (RIA) was employed to detect the levels of hyaluronic acid, laminin,type Ⅲ precollagen and type Ⅳ collagen in the arachnoid membrane. In the meantime, arachnoid cell's morphology and collagen distribution in the subarachnoid space were investigated by electron microscope. Results Results of RIA detection showed increase of Type Ⅲ precollagen level (peak at the second week), obvious higher levels of LN and HA but insignificant change of type IV collagen after subarachnoid hemorrhage. However, dexam- ethasone treatment decreased type Ⅲ precollagen level. Electron microscope found that arachnoid cells pres- ented accentruated bioactivity after subarachnoid hemorrhage, with significant increase of arachnoidal colla- gen fibers from one week after suharachnoid hemorrhage, continuing for 3 weeks. Dexamethasone treatment resulted in low density of mitochondria and sparsed arachnoidal collagen fibers. Conclusions Extracellu- lar matrix (ECM) increases in arachnoid membrane after subarachnoid hemorrhage and participates in a- rachnoid fibrosis. Dexamethasoue can relieve arachnoidal fibrosis after subarachnoid hemorrhage, as pro- rides fresh way for prevention and treatment of post hemorrhagic hydrocephalus.

Objective To discuss how to practise and consummate to shoot and assess the portfilm for radiotherapy. Methods Double radiography technique was used to take a portfilm. The reference mark points (plumbum points) were added into the field at the first exposure and the cross lines drawn based on the plumbum point images were definited as the reference coordinate to the actual field. Then, the portfilm was compared and analyzed with the simulator planning film. Results The images of both plumbum points and block boundaries were distinct in the portfilm, but the resolution and contrast of the tissue structure image was inferior to the ordinary film from simulator. However, all different structures and positions could be identified in order to assess if the actual field coincided with the radiation planning. Conclusions Although the real-time property of the portfilm is inferior to the electric portal image device (EPID), the double radiography portfilm is feasible as an important quality control method in radiation therapy due to its lower price and easier performance. The design of reference points is the key point in this technique.
