With the development of income per capita,"high personal medical expenditure" shows the wider of disease risk,which is resulted from the increasing medical payment and imperfect risk pooling.The former that is related with the excess delivery of advance medical technology and drug has been a dominating reason since 1980.And the imperfect risk pooling means the imperfect social medical insurance,of which the government should take charge.However,influenced by the reform policies of the economic systems,similar to all the transitional economies reducing the government role in healthcare financing,China has put an increasing emphasis on the payroll tax-based social insurance system and out-pockets payment,moving away from a predominantly general revenue-based financing system under the old command economy.In a conclusion,the Chinese Government should make clear the financing function,and replace fee-for-service(FFS) payment according to the distorted pricing system with aggregated pre-payment for patients covered by social insurance to mitigate the incentive for cost escalation.Meanwhile,the target of the new medical reform that should resolve the problem of high personal medical expenditure is demanding and perfecting the social medical insurance with wider risk pooling.

Bronchiolitis is a common respiratory infective disease in children, which is caused by viruses mostly. A view that bronchiolitis is a special pattern of manifestation of asthma is accepted widely. In the past few years, many agents appeared as a inducement from bronchiolitis to asthma, such as family histoty and atopy. At the same time, the life style of infants( feeding patterns,infective frequency ,environment exposure)plays a role in this process. Studying these factors will help doctors to detect people with high risk, and supply treatment earlier.

ObjectiveTo obtain data related to various periods of acupuncture treatment for rat focal ischemia and reperfusion and infer the optimal time point of acupuncture treatment by examining cerebral ROCK expression on the ischemic side in different periods of acupuncture for rats with focal ischemia and reperfusion.MethodOne hundred andeighty male adult Wistar rats were enrolled and randomly allocated to blank, sham operation, model and acupuncture groups. The model and acupuncture groups were separately divided into 5 subgroups: the 6 h, 24 h, 48 h, 72 h and 2 w subgroups. There were atotal of 12 groups, 15 rats each. An animal model of focal cerebral ischemia was made using a thread occlusion method for obstructing rat right middle cerebral artery. The carotid artery was only separated in the sham operation. Materials were taken in the blank and sham operation groups on day 2 after model making. Materials were taken for examination in every subgroup of the model group at 6, 24, 48 and 72 hours and 2 weeks after model making. Materials were taken for examination after acupuncture at Baihui(GV20), Dazhui(GV14)and Zusanli (ST36)in every subgroup of the acupuncture group at 6, 24, 48 and 72 hours and 2 weeks after model making.ResultAcupuncture markedly improved neurological deficits in rats with cerebral ischemia and reperfusion. Areduction in the neurological deficit score was largest in the 6 h acupuncture group and there was a statistically significant difference compared with the other acupuncture groups (24 h, 48 h and 72 h) (P<0.05). There was no statistically significant difference in ROCK expression between the sham operation and blank groups (P>0.05). There was a statistically significant difference in ROCK expression between the model (ischemia-reperfusion 6 h, 24 h, 48 h and 72 h) and blank groups (P<0.05). ROCK expressionreached the peak value at 6 hours after ischemia and reperfusion. There was a statistically significant point-to-point difference in ROCK expression between the acupuncture (ischemia-reperfusion 6 h, 24 h, 48 h and 72 h) and model (ischemia-reperfusion 6h, 24 h, 48 h and 72 h) groups (P<0.05). ROCK expression was down-regulated most markedly in the ischemia-reperfusion 6 h acupuncture group.Conclusion Acupuncture has an inhibitory effect on Rho/Rock in a rat model of cerebral ischemia and reperfusion. Six hours after ischemia and reperfusion is the optimal time point of acupuncture treatment. Acupuncture at that time can protect and improve post-ischemic injured brain tissue to the largest extent.

Objective An initial study on the cognition of the relationship between clinical and management staff for the purpose of improvements. Methods Questionnaires were issued to 38 clinical medical staff and 26 hospital management staff, regarding this relationship. Results Consensus is found between the two groups regarding clinical involvement in management, teamwork and exchange, and cognition on the competence and capability of the other party, P>0.05. On the other hand, however,cognitive differences are found regarding mutual penetration, power balance and implementation of policies and systems. Conclusions In-depth cooperation and understanding between the two groups and the mutual conversion of their behaviors and concepts are the cornerstones of an ideal relationship between clinical staff and management staff.
