Strategies for engineering advanced nanomedicines for gas therapy of cancer

引用

National Science Review 2020年第9期7卷 1485-1512页

作者： Yingshuai wang Tian yang Qianjun he Guangdong Provincial Key Laboratory of Biomedical Measurements and Ultrasound Imaging National-Regional Key Technology Engineering Laboratory for Medical UltrasoundSchool of Biomedical Engineering Health Science CenterShenzhen University

As an emerging and promising treatment method, gas therapy has attracted more and more attention for treatment of inflammation-related diseases, especially cancer. However, therapeutic/therapy-assisted gases（NO, CO, H2S, H2, O2, SO2and CO2） and most of their prodrugs lack the abilities of active intratumoral accumulation and controlled gas release, resulting in limited cancer therapy efficacy and potential side effects. Therefore, development of nanomedicines to realize tumor-targeted and controlled release of therapeutic/therapy-assisted gases is greatly desired, and also the combination of other therapeutic modes with gas therapy by multifunctional nanocarrier platforms can augment cancer therapy efficacy and also reduce their side effects. The design of nanomedicines with these functions is vitally important, but challenging. In this review, we summarize a series of engineering strategies for construction of advanced gas-releasing nanomedicines from four aspects:（1） stimuli-responsive strategies for controlled gas release;（2） catalytic strategies for controlled gas release;（3） tumor-targeted gas delivery strategies;（4）multi-model combination strategies based on gas therapy. Moreover, we highlight current issues and gaps in knowledge, and envisage current trends and future prospects of advanced nanomedicines for gas therapy of cancer. This review aims to inspire and guide the engineering of advanced gas-releasing nanomedicines.

为合理利用三峡库区消落带优良草本植物进行退化植被恢复,并探索恢复过程中草本植物的最佳混植比例,选取三峡库区消落带适生先锋草本植物牛鞭草(hemarthria compressa)(H)和狗牙根(Cynodon dactylon)(C)为研究材料,于2016年4月29日在盆栽控制条件下设置3种不同水分条件(对照组——CK组、浅淹组——SF组、全淹组——TF组)、7种配置比例,每盆牛鞭草与狗牙根株数分别按2株进行递增与递减,具体的配比分别为H0C12,H2C10,H4C8,H6C6,H8C4,H10C2、H12C0,比较研究混植条件下牛鞭草与狗牙根在水淹环境中的生长及二者的竞争作用。研究发现:(1)无论在单植还是二者混植条件下,水分胁迫均显著降低狗牙根与牛鞭草生物量,且牛鞭草对水淹胁迫的响应更敏感;(2)狗牙根和牛鞭草的生长均具有明显的密度制约效应,但狗牙根的反应更为强烈;(3)不同水分与密度条件下,混植体系总相对生物量均大于1。在CK组,狗牙根与牛鞭草表现出竞争关系;在SF组和TF组,二者之间的竞争作用减小,表现出一定的促进作用。综合分析本试验不同水分与密度条件下牛鞭草与狗牙根的总生物量、根冠比、竞争系数(相对总生物量),发现常规供水处理下牛鞭草和狗牙根的最佳配置比例为H2C10,而浅水淹和深水淹处理下最佳配置比例为H8C4。研究结果可以为三峡库区消落带不同海拔位草本植被的恢复及管理提供依据,也为生态类型相同或相似地区人工恢复草本植被提供理论参考。

种痘样水疱病样淋巴组织增生性疾病是一种特殊的皮肤淋巴细胞增殖性疾病,与EB病毒感染有直接的关系。该病在东亚地区,包括日本、中国等地报告较多。种痘样水疱病样淋巴瘤容易发生在儿童,表现为面部、手背等光暴露部位为主的丘疱疹,愈后常遗留萎缩性瘢痕。患者常并发有系统表现,如发热、淋巴结增大,肝脾增大等,部分患者预后不良。种痘样水疱病样淋巴组织增生性疾病属于谱系性疾病,二者之间常无法严格区分,临床常见到种痘样水疱病转化为种痘样水疱病样淋巴瘤的病例。该文简要综述了种痘样水疱病样淋巴组织增生性疾病的临床和组织病理特点、发病机制以及治疗进展。
