目的探讨经新辅助放化疗(NCRT)的局部晚期食管鳞癌(ESCC)患者行根治性切除术后达到病理完全缓解(pCR)的影响因素,比较NCRT(40 Gy分20次)后达到pCR与否的两组ESCC患者的临床疗效及预后。方法在一项前瞻性临床试验所收集的患者中,选取2015年6月至2019年10月于天津医科大学肿瘤医院经NCRT后行根治切除术的87例ESCC患者。将上述患者分为术后pCR组(35例)和非pCR组(52例),回顾其临床病理特征并完善后期随访,运用Kaplan-Meier及Cox回归等方法对两组患者的生存预后及影响因素进行比较。结果经NCRT后,有40%的手术患者达到pCR。单因素分析显示,术后pCR组和非pCR组患者的无瘤生存(DFS)期(39.3∶14.1个月,P<0.01)、总生存(OS)期(64.0∶25.2个月,P<0.05)的差异均有统计学意义。多因素分析显示,术后pCR情况、患者的年龄分组、原发多病灶与否、放化疗后的疗效评价情况及术后病理结果均为影响患者生存预后的重要因素,两组差异均有统计学意义(P<0.05)。结论ESCC经NCRT后pCR状况和患者的生存预后密切相关,且术后pCR具有预测ESCC患者长期生存临床预后的重要价值。

OBJECTIVE To evaluate the curative effect of external beam radiothera-py (EBRT) and brachytherapy (BT) for tongue carcinoma. METHODS From 1991 to 2003, 35 patients received EBRT and BT in our department. We analyzed their curative and side effects retrospectively. RESULTS Local control was 80%. The 3-year overall (OS) and disease specific survival (DSS) rates were 75% and 79%. One patient developed metastases. Three patients (9%) developed different late complications. CONCLUSIONS Local regional control, survival, and complications in patients with tongue carcinoma treated by EBRT and BT have been satis-factory.

Magnetically actuated mobile robots demonstrate attractive advantages in various medical applications due to their wireless and programmable executions with tiny sizes. Confronted with complex application scenarios, however, it requires more flexible and adaptive deployment and utilization methods to fully exploit the functionalities brought by magnetic robots. Herein, we report a design and utilization strategy of magnetic soft robots using a mixture of magnetic particles and non-Newtonian fluidic soft materials to produce programmable, hardened, adhesive, reconfigurable soft robots. For deployment, their ultrasoft structure and adhesion enable them to be spread on various surfaces, achieving magnetic actuation empowerment. The reported technology can potentially improve the functionality of robotic end-effectors and functional surfaces. Experimental results demonstrate that the proposed robots could help to grasp and actuate objects 300 times heavier than their weight. Furthermore, it is the first time we have enhanced the stiffness of mechanical structures for these soft materials by on-demand programmable hardening, enabling the robots to maximize force outputs. These findings offer a promising path to understanding, designing, and leveraging magnetic robots for more powerful applications.

目的探讨局部晚期不可手术食管癌患者行根治性同步放化疗的研究进展。方法以“locally advanced esophageal cancer、radiotherapy”为英文关键词,“局部晚期食管癌、放疗”为中文关键词在PubMed和中国知网数据库进行检索,检索时间为自建库至2022年10月。共检索到英文文献1 668篇,中文文献138篇。纳入标准:(1)局部晚期食管癌的流行病学、放疗技术和剂量、放疗靶区范围、同步化疗方案以及新辅助放化疗;(2)放疗联合免疫检查点抑制剂在局部晚期食管癌治疗中的研究进展。排除标准:(1)综述类文献及个案报道;(2)重复的临床试验;(3)Ⅰ期临床试验。共纳入文献57篇(中文5篇,英文52篇)。结果局部晚期不可手术食管癌目前的主要治疗方式仍是根治性同步放化疗。放疗技术首选调强放射治疗(IMRT),放疗靶区采用累及野照射(IFI)。放疗剂量的提高和同步化疗方案的改变并未提高患者的治疗疗效。经过诱导放化疗后降期的患者也可能有手术机会,从而获得更好的生存获益。食管癌免疫治疗的相关临床试验正在进行,免疫治疗的添加有可能带来更好的生存获益。结论局部晚期不可手术食管癌的治疗需要成熟可靠的筛选模式,需针对每位患者制定个体化治疗方案。

This paper addresses the planning problem of parallel DC electric springs (DCESs). DCES, a demand-side management method, realizes automatic matching of power consumption and power generation by adjusting non-critical load (NCL) and internal storage. It can offer higher power quality to critical load (CL), reduce power imbalance and relieve pressure on energy storage systems (RESs). In this paper, a planning method for parallel DCESs is proposed to maximize stability gain, economic benefits, and penetration of RESs. The planning model is a master optimization with sub-optimization to highlight the priority of objectives. Master optimization is used to improve stability of the network, and sub-optimization aims to improve economic benefit and allowable penetration of RESs. This issue is a multivariable nonlinear mixed integer problem, requiring huge calculations by using common solvers. Therefore, particle Swarm optimization (PSO) and Elitist non-dominated sorting genetic algorithm (NSGA-II) were used to solve this model. Considering uncertainty of RESs, this paper verifies effectiveness of the proposed planning method on IEEE 33-bus system based on deterministic scenarios obtained by scenario analysis.

目的:原发性中枢神经系统淋巴瘤(Primary central nervous system lymphoma,PCNSL)指原发于中枢神经系统,无其它系统播散的淋巴瘤。近年来发病率呈上升趋势且预后较差。本研究目的在于探讨PCNSL的合理诊断方法及治疗方式。方法:回顾性分析自1993年6月至2006年6月经病理证实的21例原发性中枢神经系统淋巴瘤的临床特征、诊断方法及治疗方式。采用SPSS11.5软件包进行统计学分析。结果:男性12例,女性9例,中位年龄50岁(46～55岁)。单发病灶15例,多发者6例。CT、MRI检查示明显的肿物占位效应,边界清楚,伴周围水肿。病理检查均为B细胞淋巴瘤,脑脊液未见癌细胞。3例行立体定向穿刺活检,18例行手术治疗完全或部分切除肿瘤。17例术后或立体定向穿刺术后行放、化疗综合治疗。10例术后先行放疗后行化疗,7例先行化疗后行放疗。Kaplan-Meier分析全组中位生存期(Mediansurvivaltime,MST)22.6个月,2年生存率44.5%。经Log-Rank检验,先放后化组与先化后放组的生存期未见统计学差异(P=0.0547)。前者中位生存期36个月,2年生存率66.7%;后者中位生存期19个月,2年生存率35.7%。结论∶原发性中枢神经系统淋巴瘤采用化疗和放疗综合治疗有望提高生存率。手术的意义仅仅在于取活检,并不能延长生存期。对于影像学高度怀疑的病例应行立体定向穿刺活检明确诊断,不必手术。放化疗的顺序对于患者总生存期并无影响。但先放后化组与先化后放组的2年生存率、中位生存期仍然存在较大差异。先放后化组好于先化后放组。
