Self-assembly of mixtures of two diblock copolymers and nanorods(层状二嵌段共聚物与纳米棒共混体系的自组装)
Zhejiang Daxue xuebao. Lixue ban, 2012 采用耗散粒子动力学(DPD)方法研究了层状二嵌段共聚物与纳米棒共混体系的自组装行为.系统地考虑了棒的粒子数比、长度及棒与高分子间的相互作用等因素对混合体系自组装的影响.一系列的构型及相转变都是在共聚物的相分离与纳米棒的聚集相行为共同作用下的结果.当把纳米棒掺入到高分子体系时，从熵和焓的角度可以更本质地理解共混体系的自组装，尤其是棒的相行为.从焓方面，纳米棒与各高分子链段间相互作用决定了棒的分布；从熵方面，棒的各向异性、相区域的空间约束及高分子链的构象熵共同决定了棒的取向.

Periostin 对接触性超敏反应中的中性粒细胞调控作用的影响
Zhongshan Daxue xuebao. Yixue kexue ban, 2020 【目的】探讨在小鼠耳肿模型炎症反应发生早期Periostin对中性粒细胞的调控作用。【方法】每组取30只，肿耳模型采用DNFB（1-氟-2，4-二硝基苯）致敏剂分别涂抹野生型小鼠（WT）和Periostin-/-小鼠（POSTN-/-）。在造模后24h，使用螺旋测微器分别进行耳廓厚度测量；免疫组化染色、流式细胞分析的方法检测耳廓组织炎症细胞以及中性粒细胞浸润情况；实时荧光定量PCR（Q-PCR）分析中性粒细胞相关细胞因子、趋化因子的表达水平。【结果】致敏剂致耳肿模型前2组小鼠耳朵厚度经测量无统计学差异 ...

血清炎症细胞因子检测对预警子宫内膜癌术后深静脉血栓的应用分析
Zhongguo shiyan zhenduanxue, 2022 目的 探讨血清炎症细胞因子检测对预警子宫内膜癌术后深静脉血栓（DVT）的应用分析。方法 收集2017年3月到2021年3月收治的56例子宫内膜癌手术后发生DVT患者临床资料，将其纳入DVT组，另选取同期56例术后未发生DVT患者临床资料，将其纳入非DVT组。两组术前均测定血清炎症细胞因子水平[中性粒细胞、抗肿瘤坏死因子-α(TNF-α)、白细胞介素-6(IL-6)、白细胞介素-1β(IL-1β)、白细胞介素-8(IL-8)]，并分析其检测效能。结果DVT组患者血液中性粒细胞计数高于非DVT组 ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Cross‐scale assembly of metal (sub) nanoparticles and/or single atoms into millimeter/nanostructured metal monolithic catalysts (Min‐SMCs) is highly appealing for sustainable water cleanup, due to energy‐efficient catalyst recyclability, high infrastructure compatibility, and low metal‐releasing risks.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT VO2 is a promising thermochromic material, but it is still limited by low transparency, weak solar modulation, and poor stability. Here, we develop a coordination‐compound‐derived strategy to construct a hierarchical BiVO4/VO2@BiVO4 film with a core–shell@nanosheet structure.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.

Zhongguo shiyan zhenduanxue, 2008 目的提出125I粒子组织间植入对肺癌细胞A549的有效剂量,确定125I粒子组织间植入对缩小肺癌肿瘤的有效性。方法建立裸小鼠皮下肺癌移植瘤模型,分三组:对照组、空白组、125I粒子植入组。从粒子植入日起观察记录肿瘤大小变化,绘制肿瘤大小变化曲线。植入粒子后第28天处死动物,取瘤,测量最终体积大小及病理分析。结果肺癌细胞A549粒子植入组和对照组、空白组相比效果明显。结论证实了125I粒子对缩小肺癌肿瘤的有效性。125I粒子计量在0.8 mCi对肺癌细胞A549肿瘤缩小的效果明显。

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Integrating light emission and electromagnetic wave (EMW) absorption into a single material opens up possibilities for multienvironmental applications. Herein, we propose a novel “molecular engineering‐pyrolysis conversion” strategy to construct a bifunctional system with tunable photoluminescence and efficient EMW absorption performance.
