目的 研究结肠黑变病(melanosis coli,MC)对结肠息肉的影响。方法 从2014年1月—2017年1月在石河子大学医学院第一附属医院行电子结肠镜的21 708例患者中选取符合条件的522例结肠黑变病患者组成MC组,随机选取569例患者组成非MC组,分析比较2组的一般情况及与结肠息肉的关系,非正态分布的计量资料以中位数表示,采用秩和检验,两组计数资料采用χ²检验。结果 结肠黑变病组年龄中位数为64岁(51～73岁),非结肠黑变病组年龄中位数为54岁(47～64岁),2组性别无统计学差异;MC组、非MC组结肠息肉检出率分别为47.8%和40.2%,P=0.013,差异有统计学意义;在病理类型上2组均为炎性息肉检出率最低,腺瘤性息肉检出率最高分别达 58.0%和51.5%,病理类型无统计学差异;在盲肠及降结肠检出率均很低,多发部位、直肠、乙状结肠检出率相对较高,但差异均无统计学意义;结肠息肉大小集中在0~9 mm范围内,2组所占百分比分别高达92.0%和91.3%,≥20 mm息肉检出率均很低,分别为0.40%,0.44%,息肉大小无统计学差异。结论 MC组息肉检出率高于非MC组,差异有统计学意义;2组结肠息肉病理类型、发病部位、息肉大小差异均无统计学意义。

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.

目的 了解住院老老年心房颤动(atrial fibrillation,AF)患者的临床特征及抗凝现况。方法 收集2015年6月—2017年9月住院老老年(≥80岁)房颤患者的抗凝用药,合并疾病,合并用药等临床信息,统计并分析,非正态分布的计量资料以中位数表示,采用秩和检验,两组计数资料采用χ²检验。结果 621例老老年患者根据性别分为男女两组,男354人,女267人,159例患者(25.6%)使用华法林,33例患者(5.31%)使用达比加群,30例患者(4.83%)使用利伐沙班,抗凝总人数为222例(35.75%)。174例患者(28.02%)使用阿司匹林,27例患者(4.35%)使用氯吡格雷,抗血小板总人数为201例(32.37%)。余198例患者(31.89%)未使用任何抗血小板或抗凝药物。结论 老老年房颤患者目前抗凝率低,抗凝药物以华法林为主。

Objective This study investigated the clinical characteristics and antithrombotic status in elderly patients with atrial fibrillation AF. Methods In this study, we collected, analyzed and characterized the data of the patients hospitalized at the First Affiliated Hospital of Shihezi Medical University from June 2015 to September 2017. Results 621 cases of elderly patients were divided into two groups according to their gender between men and women, 159 patients (25.6%) take warfarin, 33 patients (5.31%) with dabigatran, 30 patients (4.83%) uses of rivaroxaban, the total number of anticoagulation is 222 (35.75%),174 patients (28.02%) were treated with aspirin, and 27 patients (4.35%) used clopidogrel, and the total number of antiplatelet agents was 201 (32.37%). 198 patients (31.89%) did not use any antiplatelet or anticoagulant drugs. Conclusion patients with atrial fibrillation anticoagulant rate is low, and the anticoagulant is mainly warfarin.
