Objective To analyze the clinical risk factors for chronic complications in patients with type 2 diabetes and their correlation with bone mineral density and 1,25-dihydroxyvitamin D3. Methods A total of 163 patients with type 2 diabetes mellitus were selected as research subjects and were divided into complication group and non-complication group according to the presence or absence of chronic complications. The independent related factors for chronic complications in patients with type 2 diabetes mellitus were analyzed. Spearman rank correlation analysis was used to evaluate the correlation between bone mineral density, 1,25-dihydroxyvitamin D3 and chronic complications. Results Among the 326 patients with type 2 diabetes mellitus, 202 developed chronic complications (61.96%), including 71 cases of cardiovascular disease, 59 cases of neuropathy, 33 cases of renal lesion, and 28 cases of retinopathy. There were statistically significant differences in the duration of diabetes mellitus, fasting blood glucose, systolic blood pressure, glycosylated hemoglobin, triglyceride, low density lipoprotein cholesterol, serum creatinine, bone mineral density, and 1,25-dihydroxyvitamin D3 between the complication group and the non-complication group (P<0.05). Logistic multivariate regression analysis showed that the duration of diabetes mellitus, systolic blood pressure, glycosylated hemoglobin, ow density lipoprotein cholesterol, serum creatinine, bone mineral density, and 1,25-dihydroxyvitamin D3 were all independent related factors for the occurrence of chronic complications in patients with type 2 diabetes mellitus (P<0.05). Spearman correlation analysis showed that bone mineral density and 1,25-dihydroxyvitamin D3 were negatively correlated with chronic complications (P<0.05). Conclusion Bone mineral density and 1,25-dihydroxyvitamin D3 in patients with type 2 diabetes mellitus are closely related to chronic complications.

Objective:To investigate the expression of hsa_circ_0019413 in the peripheral blood of patients with primary Sj?gren's syndrome (pSS) and its role in the development of pSS disease.Methods:Microarray screening of circ ribonucleic acid (circRNA) changes was first performed in the peripheral blood of 4 pSS patients and 4 healthy controls. Real-time quantitative reverse transcription polymerase chain reaction (qPCR) was used to verify the difference in the expression of hsa_circ_0019413 in the peripheral blood of 30 pSS patients and 30 controls. By establishing the receiver operating characteristic (ROC) curve, the potential diagnostic value of hsa_circ_0019413 in peripheral blood was analyzed, and the expression level of hsa_circ_0019413 was correlated with the clinical presentations of patients with pSS.Results:① By microarray analysis, 437 circRNAs were differentially expressed between the two groups (FC≥2.0, P<0.05), of which 365 were up-regulated and 72 were down-regulated. ② The expression level of hsa_circ_0019413 in pSS patients was significantly higher than that in healthy controls by qPCR. The difference between the two groups was statistically significant ( P<0.05). It showed that hsa_circ_0019413 in peripheral blood of pSS patients had potential diagnostic value by ROC curve analysis [area under the curve (AUC)=0.883, 95% CI (0.782, 0.984), P<0.01]. ③ The expression level of hsa_circ_0019413 was positively correlated with the ESSDAI, ANA, titer of the pSS patients by correlation analysis ( r=0.721, P=0.012; r=0.625, P=0.040), but not with (immunoglobulin (Ig)G or erythrocyte sedimentation rate (ESR). Conclusion:Hsa_circ_0019413 in the peripheral blood may be involved in the development of pSS and may be a biomarker for the diagnosis of pSS.

Objective To evaluate the value of anti-carbamylated protein (CarP) antibody in the diagnosis of rheumatoid arthritis (RA).Methods The clinical data and serum of 247 in-patients with joint pain of Department of Rheumatology,General Hospital of Ningxia Medical University admitted during September 1,2015 to June 1,2016 were collected and divided into two groups according to the final diagnosis:RA group (case group) which included 126 patients and the non-RA group which included 121 patients (control group).The concentration of anti-CarP antibody in serum was measured by enzyme linked immunosorbent assay (ELISA).The serum rheumatoid factor (RF) and anti-cyclic citrullinated peptide (CCP) antibodies were detected at the same time.Mann-Whitney U nonparametric test for statistical analysis,receiver operating characteristic curve (ROC) was drawn to determine the cut-off value of anti-CarP antibody to RA diagnosis and to analyze its diagnostic efficacy.Results The ROC curve showed that the anti-CarP antibody had a cutoff value of 63.77 U/ml,with the sensitivity of 74.60％,and specificity of 71.07％.Compared with RF and anti-CCP antibody,the area under the ROC curve (A) were:Aanti-cyclic citrullinted peptide(anti-CCP)antibody (0.88)＞ARF (0.85)＞Anti-CarP antibody (0.78).There was no significant difference between the Aanti-CCP antibodies and ARF as well as ARF and Aanti-CarP antibodies (Z=1.29,P=0.20;Z=1.30,P=0.20),but there was significant difference between Aanti-CCP antibody and A anti Carp antibody (Z=2.28,P=0.02).Conclusion Anti-CarP antibody has certain value in the diagnosis of RA,and can be used as the serological index for RA diagnosis.
