低强度聚焦超声触发PLGA阿霉素在细胞内空化增加乳腺癌细胞死亡
Zhongshan Daxue xuebao. Yixue kexue ban, 2021 目的探讨低强度聚焦超声能否触发聚乳酸-羟基乙酸共聚物（PLGA）包裹阿霉素在细胞内的空化作用以增加4T1肿瘤细胞的死亡。方法采用双乳化溶剂蒸发法制备了负载阿霉素的聚乳酸-羟基乙酸共聚物（PLGA）纳米气泡。设立细胞内释药组，细胞外释药组，传统给药组，单独超声组和对照组。用流式细胞仪检测各组细胞的死亡情况，用细胞活力检测试剂盒（CCK8）检测各组的细胞增殖，细胞划痕检测各组的侵袭情况。结果超声组细胞核的红色荧光平均强度高于对照组，差异具有统计学意义（t=16.627，P<0.001）；聚乳酸 ...

浙江大学学报. 医学版副黏病毒是一类重要的呼吸道病原体，在儿童感染性疾病中具有重要临床意义。其感染过程中可诱导多种形式的程序性细胞死亡（PCD），这些PCD形式在病毒复制、传播及宿主免疫应答中发挥关键作用，显著影响病毒的生命周期及疾病进展。一方面，PCD通过清除被感染细胞有助于限制病毒扩散并激活宿主免疫应答，从而增强抗病毒防御能力；另一方面，过度或异常的细胞死亡可能导致组织损伤和免疫紊乱，为病毒复制提供有利环境，进而加重病情。如细胞凋亡通过外源性与内源性通路参与感染控制，同时亦可能被病毒操控以增强其扩散能力 ...

Gasdermin D is required for pyroptosis and secretion of interleukin-1β [PDF]
, 2016 炎性小体是细胞内由caspase-1，ASC，NALP等组成的蛋白复合体，也是先天免疫系统的一个重要组成。炎性小体被激活后会促进白介素1β（IL-1β）和IL-18的剪切与分泌，并触发细胞焦亡的发生。细胞焦亡是近年来发现并证实的一种新的程序性细胞死亡方式，其特征为依赖于caspase-1，并伴随有促炎症因子的释放。尽管其在先天免疫和内毒素休克方面扮演着重要角色，但细胞焦亡被诱导发生的机制仍不清楚。本文通过基于CRISPR-Cas9的基因敲除方法鉴定到了gasderminD（GSDMD ...

The establishment and mechanism research in the mice model of actue liver failure [PDF]
, 2016 背景和目的：急性肝衰竭（acuteliverfailure，ALF）是一个危及生命的严重病理生理状态。它可导致肝脏合成、排泄、解毒、生物转化等功能发生严重障碍或失代偿，出现凝血功能障碍、黄疸以及肝性脑病等主要表现的临床综合征。因其死亡率极高，严重ALF的治疗是当今临床医学中最具有挑战的课题之一。为了有效地治疗ALF，制备与ALF发病经过相同、临床表现类似并可复制的物模型是解决此难题的第一步，而了解各种ALF动物模型的构建机制就显得尤为重要。本课题以氧化偶氮甲烷（azoxymethane，AOM ...
