Rare Metals, EarlyView.ABSTRACT Lung cancer remains the leading cause of cancer‐related deaths worldwide, yet immune checkpoint blockade (ICB) is often compromised by an immunosuppressive tumor microenvironment (TME) with acidosis, hypoxia, and poor T cell infiltration. Here, we develop a TME‐responsive nanoplatform (MgH2@Lip/PD‐L1) that couples hydrogen gas therapy with PD ...

Zhongguo shiyan zhenduanxue, 2015 1998年,世界卫生组织（WHO）将结核病列为全球重点防控的三大传染病之一[1]。截止2009年,全世界有超过5000万人已感染结核菌,其中的10%最终会成为活动性肺结核患者,每年约有300万人死于结核病[2]。中国结核病发病人数为131万,占全球的13.9%,在全球22个结核病高负担国家中居第2位,同时也是全球27个耐多药结核病流行严重的国家之一[3]。现今 ...

Rare Metals, EarlyView.ABSTRACT MCrAlX coatings are widely used as bond coats in thermal barrier coating systems to protect turbine blades from high‐temperature oxidation. However, their oxidation resistance is often restricted by uncontrolled microstructures, surface roughness, and aggregation of reactive elements (REs). In this study, high‐repetition‐rate femtosecond laser

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Zhongguo shiyan zhenduanxue, 2018 结核病是一种由结核分枝杆菌引起的慢性传染性疾病,现已被WHO列为需要重点控制的三大类传染病之一[1-3]。近些年来结核病的耐药率不断升高,耐药性结核病已严重威胁人类的健康[4]。因此,对结核病进行早诊断、早治疗、控制传染源至关重要[5]。本研究采用T-SPOT.TB和CLEIA两种方法检测疑似结核病患者的结核分枝杆菌的感染情况,并对两组结果进行对比分析,探讨其检测的可靠性及对结核病诊断的临床价值。

Zhongguo shiyan zhenduanxue, 2021 潜伏性结核感染(LTBI)是指人体经呼吸道感染结核分枝杆菌后,机体检测呈带菌状态,但无活动性结核病相关临床表现的状态。据统计,目前全球近四分之一人口处于潜伏结核感染状态,我国作为人口大国,每年新增结核病患者已超过100万例,虽近些年来LTBI感染率有所下降,但仍是全球LTBI负担较重的国家之一[1]。医务人员在从事诊疗、护理工作中,面临职业暴露的危险[2],医护人员是潜伏性肺结核感染的高风险人群[3],是普通人群的3倍[4-5]。本研究通过对吉林省某医疗机构内的临床医护人员进行调查 ...
