单孔胸腔镜下肺癌术后胸腔引流时间的影响因素分析北大核心

目的:探讨单孔胸腔镜下肺癌手术术后胸腔引流时间的影响因素。方法:本研究采用回顾性分析方法,回顾我院2018年01月至2019年12月原发性肺癌患者经单孔胸腔镜手术治疗的病例199例。按照术后胸腔引流时间分为两组,Ⅰ组(术后胸腔引流时间<5天)和Ⅱ组(术后胸腔引流时间≥5天)。对于影响术后胸腔引流时间的可能因素在两组间先采用单因素分析的方法筛选,再将筛选出来的对术后胸腔引流时间可能有意义的影响因素进行二项Logistic多因素回归分析。结果:经单因素分析及二项Logistic多因素回归分析结果显示:年龄≥60岁、手术部位、肺段切除术、胸膜粘连、手术时间≥180 min、术后早期下床活动是术后胸腔引流时间的独立影响因素(P<0.05)。结论:对于具有多个延长术后胸腔引流时间的独立影响因素的患者,应制定个体化管理方案,尽可能减少术后胸腔引流时间,减少住院天数,加快患者康复。     

Exploring the potential of exosomes in diagnosis and drug delivery for pancreatic ductal adenocarcinoma

Pancreatic cancer (PC) is a cancer of the digestive system, and pancreatic ductal adenocarcinoma (PDAC) accounts for approximately 90% of all PC cases. Exosomes derived from PDAC (PDAC-exosomes) promote PDAC development and metastasis. Exosomes are nanoscale vesicles secreted by most cells, which can carry biologically active molecules and mediate communication and cargo transportation among cells. Recent studies have focused on transforming exosomes into good drug delivery systems (DDSs) to improve the clinical treatment of PDAC. This review considers PDAC as the main research object to introduce the role of PDAC-exosomes in PDAC development and metastasis. This review focuses on the following two themes: (a) the great potential of PDAC-exosomes as new diagnostic markers for PDAC, and (b) the transformation of exosomes into potential DDSs.

三联预康复策略在肝癌腹腔镜肝切除术中的应用价值

目的:探讨三联预康复策略在肝癌腹腔镜肝切除术中的应用价值。方法:选取2015年1月至2018年1月四川大学华西医院胆道外科收治的120例行腹腔镜肝切除术的肝癌患者，按随机数字表法分为观察组及对照组各60例。观察组在门诊收治当日开始三联预康复策略干预，干预时间约2～4周；对照组予以常规肝癌腹腔镜肝切除术术前准备。于干预前、术前1天及术后4周分别记录六分钟步行距离(6MWT)、医院焦虑抑郁量表(HADS)评分、健康调查简表(SF-36)评分及检测血清白蛋白(ALB)、前白蛋白(PA)、转铁蛋白(TRF)水平。结果:术前1天，观察组6MWT、血清ALB、PA、TRF水平高于干预前(P＜0.05)；对照组6MWT、血清ALB、PA、TRF水平与干预前差异无统计学意义(P＞0.05)；术后4周，观察组6MWT、血清ALB、PA、TRF水平与干预前差异无统计学意义(P＞0.05)；对照组6MWT、血清ALB、PA、TRF水平低于干预前(P＜0.05)；术前1天、术后4周观察组HADS评分低于干预前，SF-36评分高于干预前(P＜0.05)；对照组HADS、SF-36评分与干预前差异无统计学意义(P＞0.05)；术前1天、术后4周，观察组6MWT、SF-36评分、血清ALB、PA、TRF水平高于对照组，HADS评分低于对照组(P＜0.05)。结论:三联预康复策略应用于肝癌腹腔镜肝切除术可明显改善患者围术期活动能力、心理状态及营养状况，加速患者术后恢复。

The role of immunosuppressive agents in the management of severe and refractory immune‐related adverse events

The advent of immune checkpoint inhibitors has improved survival in some types of cancer and brought promising prospects to cancer immunotherapy. Despite their clinical benefits, significant off‐target toxicities resulting from the immune system activation have been observed, namely immune‐related adverse events (irAEs), which pose to clinicians a new challenge of optimal management. With steroids being the mainstay of current management of irAEs, immunosuppressive agents are especially indicated for severe or steroid‐refractory cases, based on current immunopathophysiological knowledge and on extrapolations of treatment options for primary autoimmune disorders. This review focuses on the status and recent clinical progress of immunosuppressive agents in the management of severe and steroid‐refractory irAEs.     

形成性评价在本科临床教学阶段的应用和探索

Endostar,an Antiangiogenesis Inhibitor,Combined With Chemoradiotherapy for Locally Advanced Cervical Cancer

This phase II randomized clinical trial aimed to assess the efficacy and toxicity of Endostar, an antiangiogenesis inhibitor, combined with concurrent chemoradiotherapy (CCRT) for locally advanced cervical cancer (LACC). Patients with LACC were randomly assigned to either CCRT plus Endostar (CCRT+E arm) or CCRT alone (CCRT arm). All patients received pelvic intensity-modulated radiation therapy (IMRT) and brachytherapy. Weekly cisplatin was administered concurrently with IMRT. Patients in the CCRT+E arm also received concurrent Endostar every 3 weeks for two cycles. The primary endpoint was progression-free survival (PFS) and acute toxicities. The exploratory endpoint was the impact of vascular endothelial growth factor receptor-2 (VEGFR2) expression on long-term survival. A total of 116 patients were enrolled. Patients in the CCRT+E arm and in the CCRT arm had similar acute and late toxicity profile. The 1- and 2-year PFS were 91.4% versus 82.1% and 80.8% versus 63.5% (p=0.091), respectively. The 1- and 2-year distance metastasis-free survival (DMFS) were 92.7% versus 81.1% and 86.0% versus 65.1% (p=0.031), respectively. Patients with positive VEGFR2 expression had significant longer PFS and overall survival (OS) compared with those with negative VEGFR2 expression. Patients in the CCRT+E arm had significantly longer PFS, OS, and DMFS than those in the CCRT arm when VEGFR2 expression was positive. In conclusion, CCRT plus Endostar significantly improved DMFS but not PFS over CCRT alone. The addition of Endostar could significantly improve survival for patients with positive VEGFR2 expression.     

3 404例2型糖尿病患者视网膜病变患病率及其相关因素分析

目的 分析2型糖尿病（T2DM）患者视网膜病变（DR）患病率及其相关因素。方法 对3 404例2型糖尿病住院患者进行回顾性研究，根据眼科会诊结果，将患者分为3组，其中非DR组（A组/NDR组）2 562例，DR非增殖期组（B组/NPDR组）716例，DR增殖期组（C组/PDR组）126例。得出DR的患病率，比较3组患者之间临床资料及临床指标的异同，及其与DR的相关性。结果 2型糖尿病患者DR患病率达24.7%，与甘油三酯（OR=1.110，P=0.000）、糖化血红蛋白（HbA1c）（OR=1.087，P=0.000）、血尿酸（OR=1.003，P=0.000）、病程（OR=1.002，P=0.000）相关。结论 2型糖尿病患者DR患病率为24.7%，高血脂、高血糖、高尿酸血症、病程长为DR的独立危险因素。早期发现糖尿病、早期治疗糖尿病、积极控制血糖血脂血尿酸，对于减少DR的发生及延缓DR的发展意义重大。
