Aim To evaluate the influence of asthma and the effect of anti-inflammation therapy on the quality of life (QOL) in allergic asthma patients. Methods The QOL of 45 patients with asthma were investigated by collecting questionnaire before and after three months anti-inflammation treatment , at the same time the serum eosinophil cationic protein(ECP) level was detected in 20 patients. The QOL questionnaire included 4 domains, they were respiratory symptoms, physical activity limitation, emotional function and environmental stimuli. Results The factors which influenced the QOL in asthma patients ranging from high to low were environmental stimuli, respiratory symptom and emotion function and physical activity limitation. After anti-inflammation treatment, the QOL was significantly improved and the serum ECP was decreased (P

Objective To evaluate the application of optical coherence tomography (OCT) in the rat retinal light damage. Methods Albino Sprague-Dawley (SD) rats (5-8 weeks of age) were exposed to 1 000-1 400 lux of diffuse, cool, white, fluorescent light for 2, 5, and 7 d. OCT image analysis and histological measurements of the retinal thickness were performed. Animals were then sacrificed and the measured results were compared with those by histological examination. Results The sensory retinal thickness of the retina in the rats thinned progressively as the retinal degeneration was in progress. The sensory retinal thickness measured by OCT [the corresponding thickness was (179.11?12.01)?m, (159.27?12.81)?m, and (133.67?11.43)?m, respectively] was well correlated with that measured by histology [the sensory retinal thickness after exposure to the light for 2, 5, and 7 d was (144.26?9.36)?m, (116.16?11.24)?m, and (94.27?10.68)?m, respectively] (r= 0.995, P

Objective To study the Inflammation and immune stress of obese asthmatic rats by adipocytokines.Methods Fourty C57BL/6 J mice were randomly divided into control group, obese group, asthma group and obese asthma group.Mice in the control group were fed normal diet and PBS, high-fat diet(75% normal diet, 10% egg yolk powder, lard 10%, 5% sugar)and PBS in obese group, normal diet and OVA(PBS)in asthma group and fat diet and OVA(PBS)in obese asthma group.Detect the leptin, adiponectin, resistin, IL-4, IFN-γ, IL-17 content with ELISA in serum and bronchoalveolar lavage fluid(BALF).Using Pearson correlation to analyze and evaluate these factors' correlation in plasma and BALF.Results The difference of leptin, adiponectin, resistin in plasma and BALF(excepted leptin)between four groups were statistically significant (P<0.05), the leptin levels between plasma and BALF has a positive correlation(R2=0.8215, P<0.05)in obese mice, there was no correlation between plasma and BALF for the adiponectin, resistin.The adiponectin content and IFN-γ levels were also negatively correlated(R2=0.9146, P<0.05)in BALF, while there was no correlation between IL-4,IL-17 and leptin, adiponectin, resistin.Conclusion Adipocytokines has a regulatory function of the immune response in obese asthmatic rats, and participate the inflammatory reaction.

Abstact:Objective To explore the effect of different arrangement of hollow screws in treatment of femoral neck fracture.Methods The clinical data of 160 cases with femoral neck fracture from March 2010 to May 2014 in our hospital were collected.They were randomly di-vided into triangle group and inverted triangle group according to arrangement of hollow screws.The operation time,intraoperative blood loss, fluoroscopy frequency in operation,length of stay,time of fracture healing,postoperative complications,Harris score and functional recovery of two groups were recorded and compared.Results The operation time and intraoperative blood loss in inverted triangle group were lower than those in triangle group,the difference was significant(P <0.05).The shortening rate of inverted triangle group and triangle group were 10%and 26.3% respectively.The shortening rate of inverted triangle group was lower than those of triangle group,the difference was significant (P <0.05).For the fluoroscopy frequency in operation,average hospitalization time,fracture healing time,rate of nonunion and femoral head necrosis,Harris score and functional recovery,there was no statistical significance between two groups(P >0.05).Conclusion Inverted tri-angle hollow screws treating femoral neck fracture makes surgery operation easier,operative time shorter and blood loss smaller.

Objective To investigate the musculoskeletal ultrasound (MSUS) findings in Chinese knee osteoarthritis (OA) patients.Methods All the MSUS data were from the outpatients with knee OA who visited Department of Rheumatology and Clinical Immunology,Peking University First Hospital from February 2013 to August 2014.MSUS findings included number and position of osteophyte,synovitis,thickness of cartilage,and so on.Comparisons between groups were made using t test,Chi-square tests.Results Six hundreds and seventy-four patients were included.Almost all the patients (96.1％) had osteophytes,most patients had both knees osteophytes.The most common osteophyte location was femoral (85.2％),followed by tibia and the upper edge of patella.The number of osteophytes differed from none to ten,and the distribution of bilateral knee osteophytes was symmetrical in most patients.There was no significant difference in the number of osteophytes between male and female,and patients over 60 years old had more osteophytes than the patients aged 60 or below.In all bursae lesions,the suprapatellar bursa were the most commonly affected [effusion,279 (41.4％),synovial hyperplasia,189(28.0％),synovitis 24 (3.6％)].There was no significant difference in the cartilage thickness between bilateral knees.But the cartilage thickness of female patients was significantly thinner than that of men [left:(2.0±0.5) mm vs (2.5:1:0.8) mm,t=3.859,P＜0.05;right:(2.0:1:0.5) mm vs (2.5±0.8) mam,t=4.109,P＜0.05],and the patients over 60 years old had thinner cartilage than patients younger than 60 years old [left:(2.0±0.6) mm vs (2.2±0.6) mm,t=2.108,P＜0.05;right:(2.0±0.6) mm vs (2.2±0.6) mm,t=2.507,P＜ 0.05].None patient had Calcium pyrophosphate dehydrate (CPPD) deposition in the cartilage.Conclusion In the ultrasonographic findings of knee OA in China,osteophyte could be found in 96％ patients,the most common location of osteophyte is the femur area.The distribution of bilateral knee osteophytes is symmetrical in most patients.Patients over 60 years old have more osteophytes.Nearly haff patients have joint effusion,one third patients have synovial hyperplasia or synovitis.Bilateral knee cartilage degeneration is symmetrical.Women and patients over 60 years old have thinner cartilage.

Objective To evaluate the validity of assessing synovitis and tenosynovitis by using musculoskeletal ultrasound scoring systems after standardized training in Chinese doctors.Methods All participants received a 30 minutes' training for the ultrasound scoring systems of synovitis and tenosynovitis.Ten static images were applied to evaluate the changes before and after training,respectively.Each parameter was assessed by a four scale semi-quantitative system recommended by outcomes measures in rheumatoid arthritis clinical trials (OMERACT).Paired t-test was used to assess the differences before and after training.Results Thirteen rheumatologists and two ultrasonographers completed the entire procedure.Significant differences were found before and after training when assessing the severity of gray-scale of synovitis (0.61± 0.30 vs 0.45±0.23;t=2.230,P＜0.05) and power Doppler of synovitis (0.57±0.26 vs 0.31±0.18;t=2.928,P＜0.05) and tenosynotis (0.56±0.15 vs 0.31±0.16;t=5.286,P＜0.05),while no significant difference was found when assessing the gray scale of tenosynovitis (t=-1.679,P＞0.05).Conclusion Standardized training is helpful to improve the validity of ultrasound scoring systems of synovitis and tenosynovitis in Chinese rheumatologists and ultrasonographers.The validity of assessing gray-scale of tenosynovits needs improvement.
