Objective To detect the expression of T helper cells 9 (Th9) in the peripheral blood and the level of interleukin (IL)-9 in the plasma of rheumatoid arthritis (RA) patients,and to analyze the relationship between Th9 and clinical characteristics,and their possible role in the immunological pathogenesis of RA were explored.Methods Thirty-six patients with RA and 22 healthy controls were included.RA patients were divided into high disease activity group (n=22) and moderate disease activity group (n=14).Th9 cells were obtained from RA patients and healthy controls and detected by flow cytometery.The levels of IL-9 in RA patients and healthy controls were detected by ELISA tests.T-test and Spearman's correlation were used for statistical analysis.Results The expression of Th9 and the level of IL-9 of RA patients [(0.99±0.50)％,( 1.06±0.42 ) pg/ml,respectively] were significantly higher than normal controls[ (0.21±0.08)％,(0.69±0.13)pg/ml,respectively,all P＜0.01 ].Meanwhile,the expression of Th9 and the level of IL-9 in high disease activity group [ ( 1.18±0.52 )％,( 1.37±0.47 ) pg/ml ] were higher than those of the moderate disease activity group [ (0.69±0.25)％,(0.94±0.30) pg/ml ].There were positive correlations between Th9 and disease activity score(DAS) 28,erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),the number of tender joints,the number of swollen joints and rheumatoid factor (RF),the level of IL-9 respectively.There were positive correlations between IL-9 and DAS28,ESR,the number of tender joints,and the number of swollen joints.Conclusion High expression of Th9 and level of IL-9 maybe involved in the pat-hogenesis of RA,and is associated with disease activity.These results indicate that the abnormality of Th9 may play an important role in the pathogenesis of RA.

Objective To investgate the expression of Tfh and Th9 in the peripheral blood of rheumatoid arthritis ( RA),and to analyze the relationship between those cells and disease activity,organs of involvement,ect.,and to underly the possible immunological mechananism of RA.Methods Peripheral blood Tfh cells and Th9 cells,define as the CD4+ CXCR5 + ICOS+ and CD3 + CD8+ IL-9+ population,were examined by flow cytometry in 36 patients with RA and 22 case of age-and gender-matched health controls.According to 28-joint Disease Activity Score (DAS28),patients were divied into two groups:high disease activity(n=22),moderate disease activity(n=14).And then to analyzed the correlation among the Tfh,Th9 and clinical data of RA,such as ESR,CRP,RF,the number of tender joints,the number of swollen joints and bone destruction,etc..While to analyzed the correlation between Th9 and Tfh.Results The expression of Tfh (Z=-6.082,P=0.000) and Th9 (0.989±0.498 vs 0.213±0.084,t=13.063,P =0.000 )in PBMCs of RA was significantly higher than normal controls.Meanwhile,the expression of Tfh ( 3.880 ±1.255 vs 2.678±1.022,t=2.990,P=0.005 ) and Th9( 1.181 ±0.523 vs 0.686±0.254,t =4.043,P=0.000) in high activity of group were higher than those moderate.The percentage of Tfh and Th9 in the two groups were all signifieantly higher than controls(P＜0.01 ),There was a positive correlation with Tfh and DAS28 ( r =0.571,P=0.000),ESR ( r =0.375,P =0.029),CRP( r =0.357,P =0.032 ),the number of tender joints ( r=0.598,P =0.000 ),RF ( r =0.421,P =0.023 ) and anti-CCP ( r =0.421,P =0.023 ).There were no relationship with Tfh and course,morning stiffness,the number of swollen joints,bone erosion and the abnormal of EKG.There was a positive correlation with Th9 and DAS28( r=0.461,P=0.005 ),ESR(r=0.347,P=0.042),CRP(r=0.384,P=0.210),the number of tender joints(r=0.341,P=0.042),the number of swollen joints (r =0.347,P=0.038 ) and RF( r =0.379,P =0.025 ) respectively.There were no relationship with Th9 and course,morning stiffness,CCP,the abnormal of EKG,bone erosion.There was a positive correlation with Tfh and Th9 (r=0.727,P =0.000),Conclusion The expression of Tfh and Th9 were increase significantly,which those cells were close relationship with the disease activity and some data,These results indicate that the abnormality of Tfh and Th9 may play an important role in the pathogenesis of RA.

Intestinal infection is one of the most common infectious diseases in children in China, and the intestinal infection is often featured as the diarrhea the main clinical symptom. Systematically understanding the etiological characteristics of intestinal infection in children in China and efficiently detecting the pathogens are crucial on the early treatment and prevention of diseases. The detection technology of clinical pathogenic microorganisms in China is undergoing a revolutionary era from microscopic examination to metagenomic sequencing.

Objective To construct interpretation theory which is suitable to explain the connotation of interpersonal relationship among associate degree nursing students.Methods The data were collected through deep interviews.The content of interpersonal relationship was affirmed by three-level coding and comparing repeatedly.Results The core concept was gaining a feeling of belonging and it could be affected by 5 generic concepts including clinical teachers,head nurses,baccalaureate degree nursing students,patients and doctors.Conclusions Harmonious interpersonal relationship can be built according to the theory of interpretation and practice outcomes can be improved.

Objective To research the therapeutic effect and toxicity of capecitabine in elderly malignant tumor patients.Methods The data of 28 elderly malignant tumor patients were retrospectively analyzed,and RECIST standard was used to evaluate therapeutic effect as CR、PR、SD and PD.In the same time,the toxicity of capecitabine was observed.Results 28 elderly malignant tumor patients who have been treated by capecitabine were completed 2cycles therapy.The effective percentage ofthese patients Was 60.7%(CR 0 pemon,PR 11 persons,SD 6 persons,PD 11 persons).The toxicity and side effect was controlled.Incidence of vomit Was 39.3%(11 persons),marrow inhibition was 25%(7 persons),angular stomatitis was 35.7%(10 persons),and hand-foot syndrome Was 21.4%(6 persons).Conclusion The therapeutic effect of capecitabine in elderly malignant tumor patients Was favourable,and the tolerance Was well.

Objective To investigate the expression of RGC32 gene in pulmonary adenocarcinoma tissue and to explore the influence on proliferation and apoptosis of A549 cells.Methods Real-time PCR was applied to detect the expression of RGC32 gene in 36 cases of pulmonary adenocarcinoma and pericancerous tissues.RNA interference was used to inhibit the expression of RGC32 gene.After RNA interference,the expression of RGC32 gene was detected by real-time PCR,the apoptosis of the transfected cells was detected by flow cytometry and the inhibition ratio of cell proliferation was detected by methyl thiazolyl tetrazolium (MTT).Results The expression of RGC32 gene was upgraded in pulmonary adenocarcinomas tissues(1:2.2736,t=-29.185,P=0.01).After RNA interference,the expression of RGC32 gene transfected A549 cells was down-regulated significantly[(2.47±0.17)％ vs(4.65±0.26)％,t=-202.868,P=0.000].Comparing to the control cells,the apoptosis of experimental group cells increased significantly (2.9 ％ vs 45.4 ％,t=-37.915,P=0.01),and the inhibition ratio of cell proliferation increased significantly.Conclusion The expression of RGC32 gene shows an obvious upgraded in pulmonary adenocarcinoma.The low expression of RGC32 gene can induce apoptosis and inhibit proliferation of A549 cells.
