BACKGROUND Numerous studies have assessed surgical resection as a standard treatment option for patients with colorectal cancer(CRC)and resectable pulmonary metastases(PM).However,the role of perioperative chemotherapy after complete resection of isolated PM from patients with CRC patients remains *** hypothesize that perioperative chemotherapy does not provide significant survival benefits for patients undergoing resection of PM from *** To determine whether perioperative chemotherapy affects survival after radical resection of isolated PM from *** We retrospectively collected demographic,clinical,and pathologic data on patients who underwent radical surgery for isolated PM from *** survival(CSS)and disease-free survival were calculated using Kaplan-Meier ***-group differences were compared using the log-rank *** multivariate analysis,Cox regression was utilized when *** This study included 120 patients with a median age of 61.6 *** 5-year CSS rate was 78.2%,with 36.7% experiencing *** resection for isolated PM resulted in a 5-year CSS rate of 50.0% for second *** chemotherapy(P=0.079)did not enhance survival *** associated with improved survival included fewer metastatic lesions[hazard ratio(HR):2.51,P=0.045],longer disease-free intervals(HR:0.35,P=0.016),and wedge lung resections(HR:0.42,P=0.035).Multiple PM predicted higher recurrence risk(HR:2.22,P=0.022).The log-rank test showed no significant difference in CSS between single and repeated metastasectomy(P=0.92).CONCLUSION Perioperative chemotherapy shows no survival benefit post-PM resection in ***-free intervals and fewer metastatic lesions predict better *** metastasectomy is warranted for eligible patients.

The critical factor of spatial constraint,provided by the external confinement(e.g.,matrix),is often overlooked during photodynamic inactivation,despite playing a crucial role in determining the molecular photophysical process and subsequent antipathogen ***,as a proof-of-concept model,we employed two types of polymers with varying interaction energies with dopants to investigate the intrinsic relationship between spatial constraint and the essential excited-state behaviors of doped photosensitizer(4-(2-(5-(4-(diphenylamino)phenyl)thiophen-2-yl)ethyl)-1-methylquinolin-1-ium iodine,TPP).Through experimental investigation and theoretical calculations,we found that TPP tends to remain in the excited state for a shorter dwell time under weaker spatial constraints due to less restricted molecular motion in polyurethane(PU) ***,the singlet oxygen(^(1)O_(2)) generated from doped-TPP shows a 9.23-fold enhancement in PU than in the polyvinylchloride(PVC) *** light irradiation,the PU@TPP nanofiber can efficiently eliminate the coronavirus MHV-A59(≥99.9997%) at a 220,000-fold higher concentration than the infected *** antibacterial efficacy has also been demonstrated,with a killing rate of ≥99%.

开源软件已经成为现代社会的一项关键基础设施,支撑着几乎所有领域的软件开发.通过安装依赖、API调用、项目fork、文件拷贝和代码克隆等形式的代码复用,开源软件之间形成了错综复杂的供应(依赖)关系网络,被称为开源软件供应链.一方面,开源软件供应链为软件开发提供了便利,已然成为软件行业的基石.另一方面,上游软件的风险可以沿着开源软件供应链波及众多的下游软件,使开源软件供应链呈现牵一发而动全身的特点.开源软件供应链近年来逐渐成为学术界和工业界的关注焦点.为了帮助增进研究人员对开源软件供应链的认识,从整体性的角度,对开源软件供应链给出定义和研究框架;然后,对国内外的研究工作进行系统文献调研,总结结构与演化、风险传播与管理、依赖管理3个方面的研究现状;最后,展望开源软件供应链的研究挑战和未来研究方向.
