Objective To study the significance of anti-cyclic citrullinated peptide (anti-CCP),anti keratin antibody (AKA) and anti-RA33 autoantibodies (RA33)in the diagnosis of elderly-onset rheumatoid arthritis (EORA) and to explore the role of the united detection of anti-CCP, AKA and RA33 in the diagnosis of EORA. Methods The above three kinds of autoantibodies were detected in 69 patients with EORA, 73 patients with polymyalgia rheumatica (PMR) and 65 patients with osteoarthritis (OA). The anti-CCP and RA33 were measured by enzyme-linked immunosorbent assay (ELISA),and AKA was measured by indirect immunofluorescence (IIF). Results In the group of patients with EORA, the sensitivity and specificity of anti-CCP were 55.1% and 94.3%, the sensitivity and specificity of AKA were 31.3% and 91.5%, and the sensitivity and specificity of RA33 were 36.2% and 95.4% respectively, which were significantly higher than those in the groups of patients with PMR and OA. United-detection of anti-CCP, AKA and RA33 reduced the sensitivity,hut increased the specificity (100%) with higher positive predictive value. Conclusions Anti-CCP,AKA and anti-RA33 can emerge in the patients with EORA and the anti-CCP displays higher sensitivity and specificity. United detection of anti-CCP, AKA and RA33 can increase the specificity and positive predictive value (100%) and has high value in the diagnosis of EORA.

Objective Drug resistance is a major problem for the successful chemotherapeutic treatment and prognosis of cervi -cal cancer .The article investigated the role of Twist on cisplatin resistance of Hela cervical cancer cells in hypoxia microenvironment and its possible mechanism to provide an experimental basis to improve the therapeutic efficacy for cervical cancer . Methods Hela Cells were divided into two groups, normal oxygen group A (no CoCl2) and hypoxia group A (addition of 150μmol/L CoCl2 medium).6 hours later, different degrees(10-3, 10-4, 10-5, 10-6, 10-7 mol/L) of cisplatin (10 -3 , 10 -4 , 10 -5 , 10 -6 , 10 -7 mol/L) were added into two groups .24 hours later , MTT were added to measure IC 50 and growth inhibition ratio .CoCl2 were used to mimic hypoxia environ-ment.The working concentration and the treatment duration of Cispla-tin was optimized by MTT method.The expressions of Twist and MDR1 in normal oxygen group , cisplatin group , hypoxic group B and hypoxic cisplatin group B were determined by immunofluores-cence and western blot . Results The IC50 values were 10 -5.3 mol/L and 10 -4.5 mol/L of cisplatin respectively in normal oxygen group and hypoxia group, and there was significantly difference between them (P<0.05).The optimized working concentration and work time of cisplatin was 10 -5 mol/L and 24 h.Compare to the normal oxygen group (13.08 ±2.39, 29.57 ±12.80), the expres-sions of Twist (20.81 ±2.07, 24.25 ±4.51, 33.14 ±4.24) and MDR1 (35.26 ±8.41, 60.13 ±22.32, 76.00 ±9.96) was signifi-cantly higher than those in other three groups and which were the highest in hypoxic cisplatin group (P<0.05).There were significant positive correlations among them in hypoxic group and hypoxic cisplatin group (r =0.686,P <0.05;r =0.546,P <0.05). Conclusion The hypoxia microenvironment may be related to the cisplatin resistance of Hela cervical cancer cells .The possible mechanism is hypoxia activates Twist and upregulates MDR 1 expression , resulting in cisplatin resistance of Hela cells .
