简介:AbstractBiosafety equipment is the key barrier enabling high containment laboratories to handle high risk agents that may cause serious and potentially lethal infections. This perspective thoroughly analyzes the development of many kinds of key biosafety technologies, and equipment for protection of laboratory workers and for high containment laboratory facilities in China. Over more than ten years of rapid development, China has had remarkable achievements in key biosafety technologies and equipment in high containment laboratories. These technologies basically meet the needs of high containment laboratories construction in China. Furthermore, according to the current global situation regarding the prevention and control of infectious diseases and the technical development level of biosafety equipment, this paper proposes targeted suggestions and notes that China still needs to increase investment in scientific research to provide further technical and equipment support enabling us to build a community with a bright future in terms of human biosafety.

简介:摘要:目的:甲状腺结节分类诊断过程中采用TI-RADS分类法,观察该种分类方法的应用效果。方法:将我科2018年1月--2020年10月的甲状腺结节297例患者353个结节作为观察对象,并且根据分类方法不同,将患者分成一组和二组,一组使用TI-RADS分类法,二组使用ATA标准分类。结果:(1)本次总共选择353个甲状腺结节作为研究对象,其中良性结节210个,占比59.49%;恶性结节143个,占比40.50%。(2)一组和二组甲状腺结节分类后从NPV、PPV、敏感性、特异性、准确性对照中,一组分别是94.33%、76.20%、88.66%、84.13%、89.23%,二组分别是85.26%、69.68%、77.33%、71.10%、81.01%。(x2=10.021,p=0.000),结果有差异。结论:甲状腺结节诊断过程中采用TI-RADS分类法价值较高,该种方法值得在临床上推广。

简介:摘要目的探讨乳腺影像报告和数据系统(BI-RADS)对钙化的评估分类及临床应用价值。方法以美国放射协会的第4版乳腺影像报告和数据系统(BI-RADS)为准,对2012年4月-2014年9月间145例乳腺钙化疾病进行BI-RADS分类,同时利用强生麦默通活检系统,对乳腺钙化病变进行穿刺活检术,术后标本摄影,并与病理结果对照研究,总结分析乳腺良性、恶性钙化的X线形态和分布特点。结果145例乳腺钙化病变中,良性65例,恶性80例。良性钙化中以簇状和弥漫分布点状钙化占多数,均为16.92%(11/65);恶性钙化中以节段性分布的分支杆状钙化为主,占22.50%(13/80)。结论钙化的形态、分布对鉴别乳腺良性及恶性病变具有一定的价值。
