Chinese Health Economics 2017;36(6):79-81
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.

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 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.

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.

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 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.
