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 To develop an improved enzymatic method for assaying creatinine in serum and urine. Methods Cratinine iminhydrolase catalyzes the conversion of creatinine to N-methylhydantoin and ammonia,the later combines with 2-oxoglutarate and NADPH in the presence of glutamate dehydrogenase.Before beginning the reaction sequence,endogenous ammonia is removed by an “ammonia scavenger system”that involves the same auxiliary reaction.The NADPH and 2-Oxoglutarate consumed are restored through a reaction catalyzed by isocitrate dehydrogenase.The activity of this strictly magnesium-dependent enzyme is completely blocked by magnesium-complexing reagent that acts promptly whenever the reaction has started with creatinine iminohydrolase as startor.The reaction is monitored kinetically by measuring the NADPH decrease via its absorbance at 340nm.Results The method affords a simple,rapid,and sensitive assay with good precision and extended linearity.Test results compare closely with the HPLC precedure.The proposed method is not subject to interference from several metablites or from the drugs used commonly in clinics.Conclusion The method is easily automated and is suitable for routine work in clinical laboratories.

Objective To summarize the clinical experience of 3% sodium chloride in treatment of chronic heart failure with hyponatremia. Methods The 102 patients suffering from chronic heart failure with hyponatremia were treated with water limit, vasodilator, cardiotonic, diuretics, angiotensin-converting enzyme inhibitor, angiotensin Ⅱ receptor antagonist and 3% sodium chloride. Cardiac functional capacity classification (NYHA), treatment effect and hyponatremia level were compared between pre- and post- treatment. Results After treatment, heart function was statistically different as compared with that of pre-treatment (χ2=150.26, P＜0.05). The 58 cases showed distinct effect, 37 cases moderate effect, 7 cases no effect, and the percentage of total effect was 93.1%. The hyponatremia of patients with different level of heart function were (139.4±22.6) mmol/L, (138.2±23.3) mmol/L, the difference had a statistics significance compared with pre-treatment hyponatremia which were (122.9±20.5) mmol/L, (120.5±26.8) mmol/L (t=2.02, 2.04, P＜0.05). Conclusions Proper diuresis and sodium salt supplement could help to reduce the malignant risk of the patients suffering from chronic heart failure with hyponatremia and to improve the prognosis.
