RESUMEN
Objective To explore the value of human leucocyte antigen-DR53 (HLA-DR53),anti-Sa antibody and anti-cyclic citrullinated peptide antibody(anti-CCP) factors combination in rheumatoid arthritis.Methods 170 patients with rheumatoid arthritis and 50 healthy individuals in the hospital were chosen.The levels of HLA-DR53 by PCR-SSP,the levels of anti-Sa and anti-CCP by ELISA,compared their diagnostic value by consistency analysis and joint detection analysis.Results The sensibility of anti-Sa,HLA-DR53 and anti-CCP in RA were 44.07％ (P =0.00,x2 =165.214),68.65 ％ (P =0.00,x2 =9.837) and 79.45 ％ (P=0.00,x2=48.028).Consistency analysis in RA,HLA DR53,anti-CCP and anti-Sa highly consistent,OR were 3.94,38.6 and 184.52.The sensitivity and Youden index of anti-CCP were the highest.The sensitivity of anti Sa and anti-CCP parallelled was 88.51 ％.The sensitivity of HLA-DR53 and anti-CCP parallelled was 93.56％,and the spe cificity of anti-Sa and anti-CCP of RA were 100％.Conclusion There is a certain correlation between HLA-DR53,anti-Sa and anti-CCP antibody,which are related risk factors of RA,co-detection will improve the diagnosis of RA.
RESUMEN
Objective To investigate the change of homocysteine (Hcy),high sensitive C-reactive protein (hs-CRP)and Inter-leukin 6 (IL-6)in patients with Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS)complicated by Cerebral Infarction (CI).Methods Chose 55 patients with OSAHS and 56 patients with CI.All patients with OSAHS were divided into mild group,moderate group and severe group by polysomnography,and all patients were divided into simple OSAHS group,sim-ple CI group and OSAHS complicated by CI group.All the patients’sleep apnea hypoventilation index (AHI),the lowest oxygen saturation (LSpO2 ),average blood oxygen saturation (MSpO2 ),sleep apnea the longest (LAT)and the level of Hcy,hs-CRP,IL-6 were determined,and compared with 30 cases of control group.Results The AHI,LAT,Hcy,hs-CRP and IL-6 of simple OSAHS group and simple CI group were obviously higher than that in control group,LSpO2 ,MSpO2 were obviously lower,the differences were statistical significant (P<0.05).The AHI,LAT,Hcy,hs-CRP and IL-6 of OS-AHS complicated by CI group were obviously higher than that in simple groups,but LSpO2 and MSpO2 were obviously low-er,and the differences were statistical significant (P<0.05).With the aggravation of OSAHS,Hcy,hs-CRP and IL-6 were gradually increased.Hcy,hs-CRP and IL-6 were positively correlated with AHI in patients with OSAHS,correlation coeffi-cient were 0.751,0.678 and 0.635,respectively (P<0.001).Conclusion OSAHS was closely related to the occurrence and development of CI,the dynamic monitoring of Hcy,hs-CRP and IL-6 levels has a certain reference value for evaluation of therapeutic effect.
