腹部超声联合阴道灌注0.9%氯化钠诊断幼女阴道异物的临床价值

目的 分析腹部超声联合阴道灌注0.9%氯化钠对幼女阴道异物的诊断价值。方法 回顾性分析2018年1月—2021年12月就诊于赣州市妇幼保健院妇科的102例疑似阴道异物幼女临床资料。患儿均接受经腹部超声、阴道灌注0.9%氯化钠检查。以宫腔镜诊治结果作为金标准，分析经腹部超声单独检测或腹部超声联合阴道灌注0.9%氯化钠诊断阴道异物的准确性、有效性。结果 宫腔镜结果显示，患儿中阴道炎有21例（20.59%），阴道异物有81例（79.42%），其中棉絮状物、谷物、头发丝等线状物最为常见；单独诊断、联合诊断出阴道异物分别有69例和79例，与宫腔镜诊断结果的K值分别为0.689和0.897。将宫腔镜诊断结果作为金标准，单独诊断、联合诊断阴道异物的敏感性分别为0.765（95% CI：0.594，0.816）、0.951（95% CI：0.826，0.995），特异性分别为0.667（95% CI：0.563，0.786）、0.905（95% CI：0.795，0.972），准确度分别为0.745（95% CI：0.586，0.813）、0.941（95% CI：0.817，0.984），单独诊断、联合诊断的敏感性、特异性、准确度可信区间无重叠，说明有统计学意义。结论 阴道灌注0.9%氯化钠可增强幼女阴道异物在超声下的显影，提升诊断准确性、有效性，且操作简单、损伤小，起到清洁阴道作用。     

发达国家医学生器官捐献意愿研究现状的范围综述

目的了解发达国家医学生器官捐献意愿研究的目的、结果、障碍因素和解决对策。 方法以主题词和自由词联合的方式对PubMed、Web of Science、Ovid MEDLINE、Ovid EMBASE(Excerpta Medica)、EBSCOhost Complete和Cochrane Library等已发表文献数据库，以及灰色文献数据库York Centre for Reviews and Dissemination、Open Grey、ProQuest Dissertation and Theses和Mednar进行系统、全面地检索，并采用Arksey和O′Malley提出的范围综述框架进行文献资料整合。 结果共纳入17项发达国家医学生器官捐献意愿研究。研究背景主要为医学生未来对于公众器官捐献有着重要影响。研究结果表明，大多数医学生器官捐献意愿性良好，但不同亚组的研究结果不一；其最主要的障碍因素为医学生器官捐献相关知识的缺乏；解决对策主要为施予系统化、结构化和可评价的教育课程。 结论21世纪以来发达国家医学生器官捐献意愿研究方兴未艾，其研究的多层面、多角度以及揭示的问题、寻求的解决对策，可对我国现阶段医学生器官捐献的研究提供一定参考。     

Go-Ichi-Ni-San 2: A potential biomarker and therapeutic target in human cancers

Cancer incidence and mortality are increasing globally, leading to its rising status as a leading cause of death. The Go-Ichi-Ni-San (GINS) complex plays a crucial role in DNA replication and the cell cycle. The GINS complex consists of four subunits encoded by the GINS1, GINS2, GINS3, and GINS4 genes. Recent findings have shown that GINS2 expression is upregulated in many diseases, particularly tumors. For example, increased GINS2 expression has been found in cervical cancer, gastric adenocarcinoma, glioma, non-small cell lung cancer, and pancreatic cancer. It correlates with the clinicopathological characteristics of the tumors. In addition, high GINS2 expression plays a pro-carcinogenic role in tumor development by promoting tumor cell proliferation and migration, inhibiting tumor cell apoptosis, and blocking the cell cycle. This review describes the upregulation of GINS2 expression in most human tumors and the pathway of GINS2 in tumor development. GINS2 may serve as a new marker for tumor diagnosis and a new biological target for therapy.
