Exposure to traffic-related air pollutants(TRAP)has been implicated in airway allergic diseases.Recent findings include epidemiologic and mechanistic studies that shed new light on the impact of TRAP on allergic rhinitis(AR)and the biology underlying this impact.These studies have found that oxidative stress induced by TRAP could affect the axis of epithelial cell-dendritic cell-T cell towards a T-helper 2 immune response,which is the major mechanism between TRAP and AR.Further,epigenetics and microRNA might be involved in this process.Our review will summarize the most recent findings in each of these areas.

Conclusion The technique of RFCA is safe, it causes significant minor myocardial injury and takes 3 months to develop from initially resembling coagulation necrosis to fibrosis. There is no evidence of new arrhythmia occurring for late electrophysiologic sequelae of RFC lesions.

Objective To explore the charcter and thesapeutic principlc of chronic lymphocytic thyoiditis.Methods 37 patients with chronical lymphocytic thyoiditis undergoing thyroidectomy were retrospectively analyzed.Results Compared with routine frozen section(FS) in operation FNA(fine needle aspiration) and the detecting of autoantibody had coincidence of 38%.Conclusion Exept preferred choosing of FNA and the detecting of autoantibody in early time,proper operation and the choose of indication is also important.

Objective To investigate the imaging diagnostic value of the early avascular necrosis of the femoral head(ANFH) in adult.Methods There were 25 cases (34 hips) with early ANFH diagnosed by imaging and clinical data.Radiography,CT and MRI findings of ANFH were analysed comparatively.Results In the 34 ANFH included stage Ⅰ 13 hips,stage Ⅱ 21 hips.The diagnostic accurary was 32.4% for X-ray,61.8% for CT and 100% for MRI.Conclusion MRI is better than the other technique in early finding the lesions of ANFH,and the diagnostic sensitivity and accuracy of MRI are higher than that of CT and X-ray.

Objective To analyze the effect of inner diameter of pancreatic duct following pancreaticoduodenectomy on pancreatic fistula.Methods From January 1995 to December 2008,256 patients underwent pancreaticoduodenectomy were divided into four groups based on the types of pancreaticojejunostomy: end-to-side "mucosa-to-mucosa" anastomosis group(n=115),end-to-end "mucosa-to-mucosa" anastomosis group(n=71),end-to-end invaginated pancreaticojejunostomy group(n=43) and pancreaticogastrostomy group(n=27).Alternatively,238 patients were divided into two groups according to drainage ways: stenting tube for internal drainage group(n=132) and stenting tube for external drainage group(n=106).Furthermore,233 cases were divided into three groups on the basis of inner diameter of pancreatic duct: ≤0.2 cm group(n=54),0.2-0.4 cm group(n=93) and ≥0.4 cm group(n=76).Then,the incidence rate of pancreatic fistula of each group was compared.Results The incidence of pancreatic fistula was 8.20%(21/256).The incidence of pancreatic fistula for different types of pancreaticojejunostomy was as follow: end-to-side "mucosa-to-mucosa" anastomosis group(7.83%,9/115),end-to-end "mucosa-to-mucosa" anastomosis group(7.04%,5/71),end-to-end pancreaticogastrostomy invaginated group(13.95%,6/43) and pancreaticogastrostomy group(3.70%,1/27),in which there wasn't significant difference in 4 groups(?2=2.763,P=0.430).There was no significant difference of the incidence of pancreatic fistula between stenting tube for internal drainage group(9.10%,12/132) and stenting tube for external drainage group(8.49%,9/106),?2=0.126,P=0.722.The incidence of pancreatic fistula in ≥0.4 cm group,0.2-0.4 cm group and ≤0.2 cm group was respectively 0,15.05%(14/93) and 11.11%(6/54),and the difference was significant(?2=12.009,P=0.002).No correlation was found between the incidence of pancreatic fistula of different inner diameter of pancreatic duct and the types of pancreaticojejunostomy (?2=1.878,P=0.598).Conclusion The inner diameter of pancreatic duct is an important factor for postoperative pancreatic fistula. No relationship is found between the types of pancreaticojejunostomy and pancreatic fistula in this study.

Background Several cytokines,especially interleukin-1β (IL-β) involve in the breakdown of blood-retina barrier,and the signal of cytokine is transduced through protein tyrosine kinase (PTK) pathway.Objective This study was to investigate the effects of PTK inhibitor,Genistein,on IL-1β-induced blood-retinal barrier breakdown and possible mechanism.Methods The animal models of blood-retinal barrier breakdown were induced through intravitreal injection of IL-1β(10ng) in 24 clean healthy SD rats and assigned to IL-1β group and Genistein group.5μl IL-1β+1μl Genistein with 0.2,1,5μg were intravitreally injected in 12 model rats and 5μl IL-1β (2mg/L)+1μl DMSO was used at the same way in other 12 models.Evans Blue was injected in rats via jugular vein in 1 hour before sacrifice of animals and the arterial blood was collected for the detect of serum Evans Blue.The retinas of the rats were obtained in 4 and 48 hours after injection of vitreous cavity to assay the content of Evans Blue in retina.The changes of vessels and infiltration of inflammatory cells were observed with hematoxylin-eosin stain.RT-PCR was employed to determine the expression of IL-8 and MCP-1mRNA in neuroretina after intravitreal injection.Expression of MCP-1 protein was localized by immunohistochemistry.Results The ratio of retinal Evans Blue and plasma Evans Blue was significantly decreased after intravitreal injection of different doses of Genistein among Genistein groups and IL-8 group with a statistical difference (4 hours:F=7.510,P=0.010;48 hours:F=5.960,P=0.019).With the increase of time after injection of Evans Blue,the ratio of retinal Evans Blue and plasma Evans Blue was gradually reduced in comparison to IL-1β group (P＜0.05).After injection of IL-1β,the dilation of retinal vessel and adhesion of leukocyte to vessel wall were seen under the light microscope,but infiltration of less inflammatory cells was found in Genistein group.The expressions of IL-8 and MCP-1mRNA were obviously declined in retina of rats in Genistein groups compared with IL-8 group (P＜0.05).Immunochemistry indicated that the expression of MCP-1 protein in neuroretina tissue was weaker in Genistein group compared with IL-8 group.Conclusion PTK inhibitor,Genistein,can decrease IL-1β-induced permeability of vessel and maintain the integrity of blood-retinal barrier by downregulating the expression of chemokines and infiltration of leukostasis in retinal vessels.This study imply that PTK pathway plays an important role in IL-1β-induced blood-retinal barrier breakdown.
