过氧化物酶（POD）是催化H_2O_2氧化反应的生物酶,很多涉及氧化反应的临床诊断试剂盒都采用这个原料。但天然的POD易失活、价格高、实验条件和储存环境都很苛刻。拟开发一种模拟酶替代过氧化物酶。次血红素六肽（DhHP-6）是一种生物小分子,由于它稳定、实验条件温和、成本较低等优点,成为近年关注热点。将次血红素六肽（DhHP-6）替代过氧化物酶催化H_2O_2氧化,通过偶联还原型色原N-乙基-N-（2-羟基-3-磺酸基丙基）-3,5-二甲氧基苯胺（DAOS）和4-氨基安替比林4-（AAP）进行显色反应,将该体系应用于葡萄糖氧化酶（GOD）催化体系,实现血液中葡萄糖含量的测定。实验结果表明,在最佳条件下,H_2O_2的线性范围为0.69～22.0mmol/L;葡萄糖测定的线性范围为0.35～22.0mmol/L。将本法用于血样中葡萄糖测定,重复性：CV=2.6%（n=20）;稳定性：3小时内,浓度CV≤5.0%;与商品血清葡萄糖试剂进行比较,R≥0.98,平均回收率达到96.4%。结果为过氧化物酶的模拟酶研究与开发提供实验技术基础。

Due to its diverse bonding hybridization forms (sp, sp2and sp3), amorphous carbon exhibits multifaceted properties and important application prospects, which have aroused extensive research interest[1–5]. In amorphous solids, some degree of atomic short-to medium-range order is thought to be ubiquitous, and the recent synthesis of new amorphous carbon has further increased our understanding of the atomic disorder in materials [4].

The Milky Way galaxy has long been hypothesized to contain at least 100 million black holes(BHs)that are lurking in the shadows[1]and 10 times more neutron stars(NSs).Xray and radio telescopes are traditionally employed to find outbursts of BHs or NSs;however,finding BHs or NSs in quiescence is extremely *** far,only a very small number of them[2]was found,pretty much like the tip of an iceberg,and finding more of them is quite hard using traditional methods.

体外循环(cardiopulmonary bypass,CPB)介导的全身炎性反应仍然是导致术后多器官损伤的主要原因之一。由于循环炎性因子浓度与患者不良预后呈正相关,因此去除或抑制炎性因子被认为是一种有效预防术后器官损伤的手段。然而20余年的研究显示,无论是抑制还是去除循环炎性因子,临床结果均令人失望。这不得不引起我们对循环炎性因子在CPB相关炎性器官损伤中的作用进行反思,以寻找更为有效的预防手段。本文对循环炎性因子与患者预后以及目前针对炎性因子的治疗如抗体、吸附等进行阐述,讨论炎性因子在组织损伤中的作用机制和可能对策。本综述可能对预防和治疗CPB相关器官损伤措施的制定具有重要启示作用。
