Objective Studying the effect of melanosis coli (MC) on colonic polyps.Methods This is a reospectively review of patients with electronic colonoscopy in our hospital from January 2014 to January 2017. A total of 522 cases of colorectal melanosis (MC) were composed of MC group, and 569 patients were randomly selected to form a non-mc group. The comparison of basic information between the two groups and the relationship of colon polyp and colon cancer was analyzed.Results The median age of the colon melanosis group was 64 years (51~73 years old), and the median age of the non-colonic melanosis group was 54 years (47 to 64 years old), with no statistically significant differences between the two groups.The detection rate of colon polyps in MC group was 47.8%. The detection rate of colon polyps in non-mc group was 40.2%, P= 0.013, and the difference was statistically significant.The two groups of polyps had the lowest detection rate of inflammatory polyps in pathological types, and the detection rate of adenomatous polyps was up to 58.0% and 51.5% respectively, but there was no statistically significant difference between the two groups. In the cecum, the detection rate of the descending colon was low, and the detection rate of multiple sites, rectum and sigmoid colon was relatively high, but the difference was not statistically significant.The size of colon polyps was concentrated in the range of 0~9 mm, and the percentages of the two groups were as high as 92.0% and 91.3% respectively, while the detection rate of the size being more than 20mm was low, that is 0.40% and 0.44%. But there was no statistical difference between the two groups.Conclusion The detection rate of polyps in MC group was higher than that in non-mc group, and the difference was statistically significant.There was no statistically significant difference between the two groups of colon polyps pathology, pathogenesis, and polyp size.

Objective Few studies has been conducted concerned Glomerular Filtration Rate(GFR) estimationequations about Cockcroft-Gault equation(CG equation)and Chinese Modification of Diet in Renal Disease equation(c-MDRD equation)in systemic lupus erythematosus(SLE). Our study aims to assess performance of two equations for renal function evaluation in patients with SLE.Methods 193 participants were enrolled in this study. Measured GFR was obtained by renal dynamic imaging method and Serum Creatinine (SCr)was determined for each participant. eGFR was gained by CG equation and c-MDRD equation respectively. Performance of equations were compared from different aspects.Results mGFR(median), eGFR-CG(median), eGFR-cMDRD(median)of the 193 participants were 75.01,70.22,70.67 mL/(min·1.73 m²)respectively. The participants were divided into two groups including mGFR≥60 (n=108)as well as mGFR<60 mL/(min·1.73 m²)(n=85). For overall participants, bias for CG equation and c-MDRD equation were 0.64, 3.91 mL/(min·1.73 m²) respectively. In terms of precision and accuracy, CG equation was better than c-MDRD equation. In subgroup, CG equation was still superior to c-MDRD equation except for bias in CG equation which is higher than c-MDRD equation in mGFR<60 ml(min·1.73 m²).Conclusion Compared with c-MDRD equation, CG performed better in GFR estimation in patients with SLE.
