Objective:To make full use of existing variables set,study on the dynamic connection between economic growth,health input and investment benefits.Methods:Using Factor Augmented VAR(FAVAR) to draw common factors and perform VAR estimation with the variables sets.Results:The impact of economic growth on health output had two sides.Increasing health input would significantly stimulate health output and economic growth.The increase of health level would promote economic growth in short time and hamper in the long run.Conclusion:The government should increase health input and consider the health loss brought by economic growth.It should prevent the not rich but old risk with the pursuit of health benefit.

Objective:To investigate the activated state of TH1/TH2 cytokines and T lymphocytes and to explore the pathogenesis of ankylosing sondylitis.Methods:Cytokine levels of Th1(IFN-?、TNF-?、IL-2)and Th2(IL-10、IL-5、IL-4) in plasma, percentages of CD3 +、CD4 +、CD8 + T cells、B cells(CD19 +) NK cells(CD16 +56 +)and CD3 +HLA-DR +、CD4 +HLA-DR +、CD8 +HLA-DR + T cells in peripheral blood lymphocytes were detected by Flow Cytometry.Results:In patients with AS ,plasma levels of TNF-?、IL-2 were significantly lower than that of healthy controls. IL-10 were significantly higher than that of healthy controls. In AS patients, percentages of CD3 +and CD8 + T cell from peripheral blood lymphocytes were significantly lower than that of healthy controls. Percentages of CD8 +HLA-DR + T cell were significantly lower than that of healthy controls. CD4 +HLA-DR +T cell was significantly highter than that of healthy controls.Conclusion:In patients with AS , lower levels of TNF-?、 IL-2 and higher level IL-10 at plasma indicate an inclination between TH1 and TH2, such as an impaired TH1 cytokine profile and an activated TH2 cytokine profile, especially in TNF-?.

Objective: By constructing the cash flow model, it proposed the premium adjustment mechanism of critical illness insurance(CII). Methods: Based on the practical data of critical illness insurance in China, it established some actuarial assumptions and cash flow model to simulate and analyze premium adjustment mechanism of CII. Results: ( 1) Because of the deterioration of critical illness incidence rate and the change of market interest rates , CII guaranteed premium usually resents pricing risk, which showed that the cash flow is negative, sometimes accumulated cash is negative; (2) based on the criteria of insurance cost adjustment, it is suggested that when the loss rate reached more than 70%, which could permit the insurance company adjust the premium, if the loss rate reached more than 80%, it needs to compulsory the insurance companies to adjust premium. Conclusion: The study proposes the mechanism of CII premium adjustment, provides guidance for practice.

The combination of transcranial magnetic stimulation and electroencephalogram (TMS-EEG) is an effective means for understanding the network of brain functions.The development of TMS-EEG,however,has been hampered by strong TMS-induced artifacts in the electrode leads.This article first introduces the TMS technology and expounds the causes of TMS-induced artifacts.According to the source of the artifact,the study reviews the artifact removing methods reported in the recent ten years regarding TMS discharge,muscle artifacts and auditory artifacts and residual artifacts.Perspectives of the related techniques are introduced at the end of the article.It is expectable that there will be a great breakthrough not only on the TMS theory but also in clinical research due to the attractive prospect in application and high research value of TMS.TMS-induced artifacts will be well solved at that time.

Objective: To study the change of cyclic nucleotide in brain of rats induced by acute stress Method: The concentration of cAMP and cGMP in frontal lob, hippcampus, midbrain and hypothalamus were measured in 1 and 3 hours after stress respectively Results:The concentration of cGMP in hippcampus and hypothalamus were significantly higher than that of control group at 1 hour after stress (P

Objective To investigate the effects of botulinum toxin type A on the proliferation,apoptosis and ERK/MAPK signaling pathway of human hypertrophic scar fibroblasts in vitro.Methods Fibroblasts were isolated from human hypertrophic scar and cultured by tissue explant method.The cells were divided into control and botulinum toxin type A groups.The botulinum toxin group A was cultured in DMEM medium containing 0.4U/L botulinum toxin type A.The control group was cultured with DMEM alone.Cell proliferation was measured by CCK8 kit at days 1,3,5 and 7 and compared within groups.Apoptosis of fibroblasts was detected by flow cytometry which treated with botulinum toxin and control group.Western blot was used to detect the relative expression of collagen Ⅰ,p-ERK1/2 and total ERK protein in fibroblasts of control,botulinum toxin type A and U0126 groups.Results Botulinum toxin type A could significantly inhibit the proliferation of fibroblasts,the number of cells was only 68.9％ in the control group at 7th days.The apoptotic rate of botulinum toxin type A was 35.9％,which was significantly higher than that of the control group.ERK 1/2 protein expression in the three groups was not significantly different (P ＞ 0.05),while p-ERK 1/2 expression in the control group was still significantly higher,but the p-EKR 1/2 in botulinum toxin type A and U0126 group was significantly inhibited.Collagen Ⅰ was highly expressed in the control group,which was significantly higher than that in the botulinum toxin type A and U0126 groups (P ＜ 0.05).Conclusion Botulinum toxin type A can inhibit the ERK/MAPK signaling pathway and increased fibroblasts apoptosis,decreased proliferation activity and collagen Ⅰ secretion.

Objective To search for a better internal fixation method in the treatment of humeral shaft fracture by comparing biomechanics and clinical results of fracture fixation with rectangle intramedullary nail and compressed plate. Methods ①Fracture models were produced in 24 wet humeral bones of adult cadavers. The models were randomly divided into two groups fixed with rectangle intramedullary nail and compressed plate respectively. Four-point bending test, twisting test and pull test were performed on the facture models after fixation and another 12 intact wet humeral bone specimens. ②The humeral shaft fracture patients were treated with rectangle intramedullary nail (92 cases) and compressed plate (78 cases). The experimental and clinical data were analyzed and compared. Results The statistical results of bending test and twisting test revealed that the rectangle intramedullary nail was better than the compressed plate for the fixation of humeral shaft fracture (P0.05). Fracture healing time was 13 weeks in average and the rate of excellent and better function was 91.3% in the rectangle intramedullary nail fixation group, while both were 18.2 weeks and 80.8% respectively in the compressed plate fixation group. Conclusion The rectangle intramedullary nail fixation is more suitable than the compressed plate fixation for the treatment of humeral shaft fracture.
