Medical service system integration follows the logic of system innovation and development.Case studies of the UK,the USA and Australia found that medical delivery system integration is the product of a series of mixed factors.Health care financing and payment mechanism reform,physician team building,stair-cased movement to grassroots of healthcare service,shared clinical norms utilization as well as its gradual development constitute the general logic of such an integration.In the evolution process,the check and balance between the government and market,equity and efficiency have been affecting the integration process all the way.In light of these logics,China should speed up its transform of the integration concept,improve the integration elements,and strengthen the guidance of integration principles during its integration of the medical service integration.

Migraine is a kind of nerve vascular disease, characterized by hemialgia, moderate and severe, pulsating pain. Acupuncture as a safe and effective analgesic therapy, has been widely used in more than 160 countries and regions around the globe. Treating migraine with acupuncture has certain good features as effective, non-toxic side effects and untoward effect.But its mechanism is still not very clear.The cerebral blood flow study ( CBF study) is currently the most credibility of migraine pathogenesis theory.Now based on the theory of CBF study, this paper discusses the acupuncture treatment of migraine which can provide the basis for clinical treats.

AIM: To determine the low content of Ophiopogon japonicus saponin metabolite in vivo. METHODS: HPLC-MS method of determining rat's metabolite diosgenin in vivo was established after single-dose oral Ophiopogon japonicus saponin enteric microsphere. RESULTS: The detection limit was about 50 ng/mL,Linearity,precision of intra and inter-day and reproducibility of the method were good. CONCLUSION: This method accords with the analysis requirement.It can give an effective measure and foundation for studying TCM saponin bioavailability.

Objective To investigate the NAD+ - dependent protein deacetylase SIRT1 expression in the cochlea of C57BL/6 mice ,a mouse model of age - related hearing loss(AHL) .Methods A total of 46 C57BL/6 mice were used ,and were divided into 2 groups ;according the age ,there were young group (1 ~ 2 months old ,23 mice) and old group (12 ~ 16 months old ,23 mice) .ABR measurements were performed on young and old C57BL/6 mice . The expression of SIRT1 in the cochlea was detected by qRT - PCR and immunofluorescence .Results The ABR thresholds in the old mice(4 kHz :82 .7 ± 7 .32 dB SPL ,8 kHz :80 .9 ± 7 .8 dB SPL ,16 kHz :89 .3 ± 5 .5 dB SPL ,32 kHz :89 .9 ± 4 dB SPL) were significantly higher than those in the young C57BL/6 mice(4 kHz :52 .1 ± 8 .3 dB SPL ,8 kHz :40 .5 ± 6 .1 dB SPL ,16 kHz :50 .7 ± 9 .4 dB SPL ,32 kHz :57 .6 ± 11 .9 dB SPL)(P < 0 .001) .SIRT1 mRNA expression was significantly decreased in the cochlea of old C57BL/6 mice in comparison with young mice ( P <0 .01) .SIRT1 protein was abundantly expressed in the inner hair cells ,outer hair cells ,supporting cells ,strial marginal cells ,strial intermediated cells ,and spiral ganglion neurons .The positive area and the average flourescence intensity of SIRT1 protein were reduced in old C57BL/6 mice(P< 0 .001) .Conclusion The down - regulation of SIRT1 mRNA and protein expression in the older C57BL/6 mouse cochlea may be correlated with the pathogenesis of AHL .

Objective:To investigate the expression and the significance of inflammatory cytokine IL-6 through regulating Gli1 in acute pancreatitis.Methods: In this study,C57 mice were randomly divided into three groups:control group,model group,inhibitor group.caerulein intraperitoneal injection induce acute pancreatitis model.Use HE staining and amylase to testify the model successfully.Use RT-qPCR,Western blot to detect the expression of Gli1 in the pancreas,liver,lung,kidney and intestine and ELISA method to detect inflammatory cytokines IL-6.Results: Compared with control group,the expression of Gli1 is higher in model group,then the expression of IL-6 increases in inhibitor group which uses Gant61 to suppress Gli1 compared with model group.Conclusion: Gli1 may involved in the process of the distant tissue injury and repair in acute pancreatitis and through regulate its downstream cytokines like IL-6 to play a protective role in acute pancreatitis.

Objective To analyze mRNA expressions of 7 cytoklnes which influence the immune response in lym- phocytes in pleural effusion of non-small cell lung cancer patients to evaluate the effect of local tumor microenviron- ment on anti-tumor immune response and to explore the mechanism of tumor escape. Methods Detecting the mRNA expression of IL-2,INF-γ,IL-12,IL-18,IL-10,IL-4 and TGF-β 1 in lymphocytes in pleural effusion of non-small cell lung cancer patients and tuberculotic pleurisy patients on the single cell level by using in situ hybridization. Results In the pleural effusion of non-small cell lung cancer, the mRNA expressions of IL-10,TGF-β1 and IL-4 were signifi- cantly higher than those of IL-2,IL-12,IL-18 and INF-γ,as well as these of control group. The cytokine expression levels of tuberculotic pleurisy patients were very Iow, and there were no significant differences between different cy- tokines. Conclusion Type 2 cytokines are expressed predominantly in the pleural effusion of non-small cell lung can- cer. The increased co-expression of IL-10 and TGF-β1 indicates that they might act Jointly and play a critical role in the immunosuppression of non-small cell lung cancer.
