尿干化学法和离心沉渣镜检法检测穿刺羊水母体细胞污染的应用

目的　探讨一种快速简便鉴别羊水母血污染的方案。方法　选取30 例2019 年6~10 月羊水穿刺样本, 检测 羊水及母血DNA，将母血DNA 污染量换算对应体积全血量建立羊水母血DNA 污染梯度模型，运用尿干化学法及离 心沉渣镜检法检测母血污染情况。结果　羊水母血DNA 污染率为5%，10%，20% 和30%，尿干化学法检出率分别为 16.67%，60%，100% 和100%；离心沉渣镜检法检出率分别为60%，100%，100% 和100%。结论　尿干化学法及离心 沉渣镜检法联合检测可更简便快捷地进行羊水母血污染鉴定，检出率与母血DNA 污染率呈正比关系。

保留足趾的自体复合第2足趾关节移植治疗手指关节炎

目的 探讨保留足趾的自体复合第2足趾关节移植治疗手指关节炎的临床疗效.方法 2016年2月至2018年6月,共收治创伤性手指关节炎9例,其中男7例,女2例;年龄19~53岁,平均31.7岁;示指3例,中指6例;掌指关节(MP)关节炎4例,近侧指骨间关节(PIP)关节炎5例;均为创伤后继发的手指关节炎.采用游离带血供的自体复合第2足趾跖趾或趾骨间关节移植进行治疗,同时将受区废弃关节(7例)或切取自体髂骨移植(2例)修复供区骨缺损保留足趾长度,供区创面均直接关闭.术后观察手指和足趾骨折愈合情况、外形、移植关节活动度(ROM)、术后供区愈合情况和行走功能及相关并发症.结果 本组术后9例移植关节全部成活,1例足部供区行髂骨植骨微型钢板固定,术后1周伤口不愈合,考虑为内固定物排异反应,予拆除钢板改克氏针交叉固定,2周后创口顺利愈合.术后随访6~30个月,平均16.3个月.手指骨折平均愈合时间7~10周,平均8.3周,手指外观及功能良好.移植后的MP活动度为50°~75°,平均65.3°,PIP活动度为10°~85°,平均60.6°.根据中华医学会手外科学分会上肢部分功能评定试用标准评价手指功能:优5例,良3例,可1例,优良率为88.9%.足趾骨折平均愈合时间9~12周,平均10.2周,所有患者足趾外形良好,行走功能正常.2例取髂骨患者供区仅残留一条线形瘢痕,无疼痛、麻木等不适.结论 游离带血供的自体复合第2足趾关节移植治疗手指关节炎,同时应用受区废弃关节或切取自体髂骨移植修复供区骨缺损保留足趾,不仅能恢复手指关节的正常结构,使关节具有良好的功能,而且能保留足趾外形与功能,减少供区损伤,具有良好的治疗效果.     

Systematic review of optical coherence tomography usage in the diagnosis and management of basal cell carcinoma

Optical coherence tomography (OCT) is a noninvasive imaging tool used in vivo in real time for diagnosis, treatment delineation and monitoring of basal cell carcinoma (BCC). Features of BCC on OCT have been widely described and reviewed. However, the diagnostic accuracy of OCT in these various applications is unclear. We systematically reviewed the literature to assess the accuracy of OCT in diagnosis and management of BCC using the Embase and Medline databases. In total 179 unique references were identified in the initial search, of which 22 studies with 556 histologically proven BCCs were eligible. Assessment of the quality of eligible studies was undertaken using the STROBE criteria. Data extraction and quality assessment were performed independently by the two authors. This systematic review provides an overview of the clinical applications of OCT in the diagnosis and management of BCC. OCT has been suggested to be useful in the diagnosis, treatment planning and treatment monitoring of BCC. As the technology improves and its utility increases, further studies with good methodological quality will be needed to implement OCT into daily practice.
