The interdisciplinary nature of health economics brings certain difficulty to the teaching of this course, so it is very important to rationally design and use case teaching. According to the characteristics of the course, this paper put forward design ideas from the guiding ideology, selec-tion, categories and forms. This paper argued that teacher should play a leading role and create a good learning environment and grasp four parts of the implementation.

Objective To investigate the effect and significance of minimally invasive removal of intracranial hematoma on the blood-brain barrier in patients with intracerebral hemorrhage (ICH).Methods Clinical data of 20 patients with ICH were randomly selected and received minimally invasive surgery (operative group) and 20 patients with ICH received expectant treatment therapy (expectant treatment group) were analyzed retrospectively,and 20 healthy people were randomly collected for control group.The blood-brain barrier (BBB) and serum myelin basic protein (MBP) concentration were analyzed.Results The BBB index of the iperative group was 0.0075 ± 0.0007,the expectant treatment group was 0.0083 ± 0.0006 and the control group was 0.0068 ± 0.0004.The BBB index in the operative group was significantly lower than that in the expectant treatment group (P ＜ 0.05),and the BBB index in these two groups was significantly higher than that in the control group (P＜ 0.01).The serum MBP concentration in the operative group was (3.29 ± 1.55) μg/L,the expectant treatment group was (6.55 ± 3.78) μg/L,and the control group was (1.12 ± 0.48) μ g/L.The serum MBP concentration in the operative group was significantly lower than that in the expectant treatment group (P ＜ 0.05),and these two groups were significantly higher than the control group (P ＜ 0.01).Conclusions The permeability of BBB in patients with ICH are increased,the BBB index and the serum MBP concentration in patients with ICH are increased,minimally invasive surgery can reduce the lesion of cytotoxicity to BBB and cerebral edema.

Chitin is one of the most important component in fungal cell wall.Biosynthesis of chitin is a complex processes and needs several chitin synthase isoenzymes.The knowledge of structure,function and regulation of chitin synthases is mainly derived from the study of Saccharomyces cerevisiae.In contrast with the 3 chitin synthases in S.cerevisiae,7 were found in most filamentous fungi.In this review the classification and function of chitin synthases are summerized,and progress in the studies on chitin synthases of filamentous fungi which are of theoretical or medical or agricultural importance,including Aspergillus nidulans,Aspergillus fumigatus and Ustilago maydis are emphasized.Recent ad-vance of research on chitin synthase as antifungal target is also discussed.

Objective To test the diathesis-stress component in the hopelessness theory and demonstrate the mediator effect of hopelessness in depression-generating process. Methods In the 6-month longitudinal study,latent growth curve model(LGM) was used in a sample of 269 Chinese undergraduates on the base of questionnaire investigation. Results The intercept for hopelessness depression had a significant association with the intercept for negative life events (path coefficient =0.48) and depressogenic attributional style (path coefficient=0.26).The slope for hopelessness depression had a significant association with the slope for negative life events (path coefficient=0.73). The complete mediator effect of hopelessness between depressogenic attributional style and the intercept for hopelessness depression was 0.143. The complete mediator effect of hopelessness between the slope for negative life events and the intercept for hopelessness depression was 0.131. The partial mediator effect of hopelessness between the intercept for negative life events and the intercept for hopelessness depression was 0.151.Conclusion Depressogenic attributional style interacted with the occurrence of negative events to predict the occurrence of hopelessness depression. Hopelessness made partial mediator effect on the hopelessness depression-generating process.

The study is to explore the effect of paeoniflorin on the level of glucocorticoid receptor, including glucocorticoid receptor-alpha (GCRalpha) and glucocorticoid receptor-beta (GCRbeta), of peripheral blood mononuclear cells (PBMCs) in rats of collagen-induced arthritis (CIA). CIA is induced in Wistar rats by an intradermal injection of bovine type II collagen emulsified with complete adjuvant. From the 14th day after primary immunization, the CIA rats were intragastrically administered paeoniflorin 25, 50 and 100 mg x kg(-1) or triptolde 20 microg x kg(-1) or paeoniflorin 50 mg x kg(-1) + RU486 15 mg x kg(-1), once a day, for 28 consecutive days. After administration, apart from PF + RU486 group all experimental rats were took blood by removalling eyeball, then separated PBMCs. The level of GCRalpha, GCRbeta in PBMCs were examined by ELISA, and the mRNA expression of GCRalpha, GCRbeta was detected by RT-PCR. All rats were sacrificed and took the joint with no immunization. The expression of IL-1beta, NF-kappaB p65, TNF-alpha, PGE2 of synovial tissue was detected by immunohistochemistry. Paeoniflorin was able to inhibit the expression of IL-1beta, NF-kappaB p65, TNF-alpha, PGE2 of synovial tissue in CIA rats. While RU486, glucocorticoid receptor's blocker, could weaken the fuction of paeoniflorin. Meanwhile, paeoniflorin obviously induced the expression of GCRalpha and GCRalpha mRNA, while obviously inhibited the expression of GCRbeta and GCRbeta mRNA. These results indicat paeoniflorine suppresses inflammatory mediator production may be relating with it regulating GCR in PBMCs of CIA rats.

This paper reviews outpatient security policy of typical developed countries .It provides reference for outpatient security system in China .Analysts believe that the experience for Chinese reference should be acquired in the following ways:The pooling of outpatient service is an inevitable trend in the development of health insurance , which is in principle an integral part of payment and financing system; the implementation of outpatient community first diagnosis system should be adapted to the local conditions; the community first diagnosis system is a necessary condition for capitation , so it is closely related to compensation methods and the elaborate degree of outpatient treat -ment catalog;Outpatient services should be supervised and payment policies should be developed respectively .There are two supervision models about outpatient service:external supervision and self supervision , but the key is to focus on the management of outpatient doctors .External regulation should be consistent with the current regulatory approach of the situation and patients have to bear some responsibilities for outpatient treatment expenses in some proportions , but the payment cap line should not to be low .The implementation of certain preferential policies for vulnerable groups can be considered under the harmonized system to partially reduce their medical expenses .
