This paper reviews studies on the relationship between health insurance and health status both at home and abroad. First, we put forward three viewpoints on their relationship;Second, based on different data, we review the studies from three different perspectives; Third, we review the recent studies at home. The paper draws the conclusion as following:(1) most studies on observational data prove that there is relationship between health in-surance and health status. To establish the causal relationship between them, we must overcome the endogeneity of health insurance. ( 2 ) Different studies have different conclusions, which are caused by different methodology and subjects. (3)The conclusions cannot be generalized to whole populations. Future studies should focus on the effect of different health insurance on different populations.

With the rapid development and wide application of forensic DNA technology, strict management and guidance are required. Conclusion could be gained the public and judge recognition, would be more scientiifc, accurate and convincing by using the standard operation. In recent years, forensic DNA standard technology has been rapid development, but there are still insuffcient. This paper will summarize the present situation and the existing problems of forensic DNA technology standards and prospects.

Objectives: To study the apoptosis induced by homocysteine (Hcy) and the protective effects of folic acid, VE and Se. Methods: Inverted microscopy and MTT test were used to observe the protection of these nutrients on the cytotoxic effect of Hcy. DNA agarose gel electrophoresis and flow cytometry were used to observe the inhibition of these nutrients on the apoptosis induced by Hcy. The level of MDA, the activity of SOD and GSH-Px and the generation of active oxygen in cells were also measured to investigate the mechanism of the protective effects. Results: Significant effects of folic acid, VE and Se on the protection of cell damages and the inhibition of apoptosis induced by Hcy were observed. These protective effects may be the results of decreasing MDA in cells provided by folic acid, VE and Se, increasing the activity of SOD by folic acid, increasing the activity of GSH-Px by folic acid and Se, and decreasing the generation of active oxygen by VE. Conclusions: The protective effects of folic acid, VE and Se on the damage of ECV304 cell from Hcy and the inhibitive effect on apoptosis induced by Hcy might be in different mechanisms.

Objective To explore the influence of psychological first aid training on cognitive appraisal of sudden events in medical students.Methods A medical university undergraduate students were selected and divided into the training group(n=42) and the control group(n=53).The former was treated with 20 hours short-term targeted psychological first aid,and the latter was treated as blank control.The SAM and LMSQ were adopted to measure students' cognitive appraisal before and after the training.Results After the training,the training group gained significant differences (P＜ 0.05) in threat (11.95 ±3.17) vs (10.45±2.48)(t=2.426,P=0.020),challenge (12.64t2.84) vs (14.40±1.95)(t=-3.304,P=0.002),controllable-by-self (13.05±3.15) vs (14.93±2.00) (t=-3.240,P=0.002),controllable-by-others (12.40±3.10) vs (14.52±2.52) (t=-3.553,P=0.001),stressfulness (13.26±2.69) vs (12.00±1.96) (t=2.592,P=0.013) of SAM,and Physical threat ((23.88±7.59) vs (19.76±4.82),t=3.057,P=0.004) of LMSQ compared with before training.Other factors had no significant difference(P＞0.05).Compared with two groups,the training group gained significant increase(P＜0.05) on the score differences for SAM factors (challenge (t=-2.466,P=0.016),controllable-by-self (t=-2.557,P=0.012),controllable-by-others (t=-2.800,P=0.006)) than the control group,and significant reduction (P＜0.05) in physical threat (t=-2.308,P=0.023) of LMSQ.Conclusion Short-term targeted psychological first aid training has certain effects on changing cognitive appraisal about sudden events for medical students.

Objective To investigate the efficacy of microwave ablation for big liver cancer by using laparoscopy.MethodsFrom August 2000 to October 2006,28 patients with large big liver cancer(over 5 cm in diameter)was treated by microwave ablation under the guidance of a laparoscope.On each tumor nodule,3 to 5 electrode insertions was applied.And for each lesion,the treatment was performed for 1 to 3 times.Results The complete ablation rate of this series was 78.6%(22/28),and the rate of local recurrence was 35.7%(10/28).1-,3-,and 5-year survival rates were 75.0%(21/28),57.1%(12/21),and 36.4%(4/11),respectively.Conclusions Laparoscopic microwave ablation is safe and effective for liver cancer.The procedure can increased the efficacy of the microwave by enlarging the extent of the ablation.

Currently praziquantel is one of the major drugs used in treatment of schistosomiasis and other trematode infections.Recent experimental studies indicate that a new anthelmintic,tribendimidine,is used in the treatment of intestinal nematodes,also possesses effect against several species of trematodes including Clonorchis sinensis,Opisthorchis viverrini and Echinostoma caproni.Tribendimidine is even more effective against C.sinensis in rats that a single 300 mg/kg oral dose cures almost all of the animals treated,a lower cure dose than praziquantel(375-500 mg/kg).The anti-malarial drugs artemether and artesunate are not only effective in the prevention of schistosomiasis,but also effective against several species of trematodes,especially C.sinensis.The single oral dose of both drugs to cure or achieve high efficacy in infected rats is 75 mg/kg.This review summarized research progress on tribendimidine,artesunate,and artemether in experimental animals infected with C.sinensis and other species of trematodes.

Objective To discuss the problems in the development of enterprise -Web PACS, and find the solutions. Methods The author applied the standpoint of software engineering, and used the experience of other enterprises to find a fast, low-cost, well-maintainable, well-expansible way in development of enterprise-Web PACS. Results The solution is a reasonable development method for enterprise-Web PACS, and the more big the project is, the more obvious the advantage is. Conclusion It is an effective way of developing enterprise-Web PACS to use the reasonable software structure and good development platform and advanced development framework in increasing the software reusability, maintainability, improving the capacity of the secondary development ability.
