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 To explore a biodegradable drug?loaded composite scaffold and determine its bone regeneration and local long?term drug release ability. Methods In this study, RFP?loaded a novel poly (caprolactone)?b?poly (lactide?co?gly?colide)/β?TCP composite scaffold was produced using particle?leaching/freeze?drying technique. And the obtained composite scaffold was characterized by SEM, TGA, UV spectrophotometer, universal testing machine and so on. New Zealand rabbits were used to prepare bone defects, which was treated by the implantation of active artificial bone loaded with or without RFP. The blank group was untreated. Then the repairing effects of the materials were examined. Results The obtained porous scaf?fold has inter?connected and uniformly distributed pores, and the diameters of pores range from 200 μm to 300 μm. Many mi?cropores (10 μm to 50 μm) can be observed on the wall of macropores. The total porosity of the porous composite scaffold can reach as high as 83.4%; the β?TCP content of the scaffolds is 51.2%. Meanwhile, the addition of β?TCP avoided volume shrinkage compared with b?PLGC scaffold; Additionally, the porous composite scaffold has good compressive strength ( 240 kPa) and compressive modulus (1.0 MPa); And the drug loading of the scaffold was 3.2%,which could smoothly release drug for 63 days after a period of burst release for a week. All defects in the experimental groups were radiographically repaired. There were significant differences between the experimental groups and the control group. Conclusion RFP?loaded poly (cap?rolactone)?b?poly (lactide?co?glycolide)/β?TCP composite scaffold is expected to benefit in drug therapy and bone repair in the treatment of bone tuberculosis.

Objective To investigate the correlation between the prevalence of hyperuricemia (HUA) and metabolic syndrome (MS) in community residents in Xicheng District of Beijing. Methods A total of 834 permanent residents were se-lected for the survey. The values of height, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), serum uric acid (UA), fasting plasma glucose (FPG), total cholesterol (TC), triglyceride (TG) and high density lipopro-tein-cholesterol (HDL-C) were recorded. Subjects were divided into HUA and non-HUA groups. Based on four components of MS, subjects were divided into (1) MS0 group (no any component of MS), (2) MS1 group (one component of MS), (3) MS2 group (two components of MS), (4) MS3 (three components of MS) and (5) MS4 group (four components of MS). The relation-ship of HUA and components of MS was analyzed. Results The total prevalence of hyperuricemia was 12.0%in 834 sub-jects. The prevalence of hyperuricemia were significantly higher in male subjects than those of female subjects[21.8%(83/381) vs 3.8%(17/453),χ2=63.765,P<0.01]. Values of BMI, SBP, DBP, TC and TG were significantly higher in HUA group than those of non-HUA group (P<0.01). There were no significant differences in levels of HDL-C and FPG between two groups. The prevalence of overweight/obesity, hypertension, hyperglycemia and dyslipidemia were significantly higher in HUA group than those of non-HUA group (P<0.01). The prevalence of HUA gradually increased with the accumulation of MS components (χ2=46.347, P<0.01). Conclusion Hyperuricemia and metabolic syndrome are closely related. We should pay more attention to monitor the serum uric acid levels.

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 establish an animal model of oral lichen planus (OLP). Methods:Human non-erosive OLP lesion tissue was surgically transplanted into dorsal hypoderm or tongue abdomen in 10 severe combined immunodeficiency (SCID) mice, thereafter, growth and possible alterations of histopathological characteristics of the xenografts were observed for 2 weeks. Results:All the xenografts transplanted into dorsal hypoderm or tongue abdomen healed well.Partial liquefaction and subepithelial lymphocytes diffuse infiltration were observed in epithelial basement membrane in the first week after transplantation. During the subsequent week, the degenerated moiety was hardly to be seen, and the number of subepithelial lymphocytes was gradually decreased. Conclusions:The epithelia of OLP xenografts grow well in SCID mice but can not keep its histopathological features.

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.
