Learning curve of totally thoracoscopic pulmonarysegmentectomy

引用

Frontiers of Medicine 2018年第5期12卷 586-592页

作者： weibing wu Jing Xu Wei Wen Yue Yu Xinfeng Xu Quan Zhu Liang Chen Department of Thoracic Surgery The First Affiliated Hospital of Nanjing Medical University Nanjing 210029 China

Totally thoracoscopic pulmonary segmentectomy (TTPS) is a feasible and safe technique that requires advanced thoracoscopic skills and knowledge of pulmonary anatomy. However, data describing the learning curve of TTPS have yet to be obtained. In this study, 128 patients who underwent TTPS between September 2010 and December 2013 were retrospectively analyzed to evaluate the learning curve and were divided chronologically into three phases, namely, ascending phase (A), plateau phase (B), and descending phase (C), through cumulative summation (CUSUM) for operative time (OT). Phases A, B, and C comprised 39, 33, and 56 cases, respectively. OT and blood loss decreased significantly from phases A to C (P < 0.01), and the frequency of intraoperative bronchoscopy for target bronchus identification decreased gradually (A, 8/39; B, 4/33; C, 3/56; P = 0.06). No significant differences were observed in demographic factors, conversion, complications, hospital stay, and retrieved lymph nodes among the three phases. Surgical outcomes and techniques improved with experience and volume. CUSUMOT indicated that the learning curve of TTPS should be more than 72 cases.

GLOBAL LINEARIZATION OF NONLINEAR SYSTEMS

引用

Science in China,Ser.A 1988年第3期31卷 369-378页

作者：高为炳吴东南 Beijing Institute of Aeronautics and Astronautics

The general form of nonlinear system has been studied. It is concluded that under general conditions the differential equation of the nonlinear system and the nonlinear state feedback control are both linear with respect to their control variables if the system is globally linearizable by this nonlinear state feedback control. Global linearization via state transformation has been considered. Sufficient conditions expressed in form of the given system have been obtained, which are simple in form and easy to check. Finally, the simultaneous linearization by state feedback and state transformation and the synthesis problems have been discussed.

Novel thermo-responsive cellulose papers were prepared via grafting poly(di(ethylene glycol)methyl ether methacrylate)(PDEGMA)by activators regenerating electron transfer(ARGET)and atom transfer radical polymerization(ATRP).Attenuated total refraction Fourier-transform infrared spectroscopy(ATR-FTIR)and scanning electron microscopy(SEM)measurements of the modified paper showed that PDEGMA brushes were successfully grafted on the paper *** thermal stability of the papers before and after grafting was evaluated by thermogravimetric analysis(TGA).The PDEGMA-grafted paper exhibited a two-step thermal degradation process,and presented thermo-responsive *** was hydrophilic at room temperature but changed rapidly to highly hydrophobic when the temperature rose above 50℃.

以乙二胺四乙酸二钠(ethylenediamintetraaceticaciddisodium,EDTA)为鳌合剂,在水溶液络合体系中采用电沉积法制备了CuSCN半导体薄膜,应用电子隧穿成核和表面态热激发机理以及Mott-Schottky曲线分析了沉积电位和温度对薄膜结构和半导体性质的影响。结果表明:室温下,价带电子隧穿产生的电流与表面态空穴热激发电流在同一数量级,表面态空穴热激发电流不随电位改变,价带电子隧穿电流的变化趋势反映了整体电流的变化。随着阴极电位的升高,由于价带电子的隧穿几率变化,晶粒尺寸先减小后增大;半导体空穴浓度减小,p型性质减弱。由于沉积反应受活化能控制,在高温条件下主要表现为晶粒生长,导致晶粒尺寸增大,薄膜致密度降低;同时也使半导体空穴浓度减小,p型性质减弱。

由于肺段支气管、血管的解剖变异繁多,胸腔镜肺段切除术的技术较肺叶切除术更加精细复杂。术前三维CT支气管血管成像(three dimensional-computed tomography bronchography and angiography,3D-CTBA)可以显示肺段的解剖结构以及肺段支气管、血管的变异,明确肺部结节的肺段归属,有助于制定手术计划。术前结节定位在胸腔镜肺段切除术中起着重要作用。解剖性肺段切除术的技术包括:分别切断靶段动脉、支气管、段内静脉,保留段间静脉,采用膨胀萎陷法确定肺段间交界面,使用电刀和/或切割缝合器分离段间肺组织。恶性结节行肺段切除术时必须确保切缘宽度≥2 cm,或≥肿瘤直径,同时需要进行N1、N2站淋巴结采样及冰冻切片分析。胸腔镜解剖性肺段切除术的并发症发生率较低。肺段与肺叶的解剖关系为,若干个呈不规则锥形结构的肺段组成一个肺叶,段间静脉行走于肺段间。本中心探索出一种按照锥形结构原理自肺叶中分离出肺段的方法,并命名为"锥式肺段切除术"。"锥式肺段切除术"的技术涵盖了准确判断和处理靶段支气管和血管以及解剖性分离段间交界面,可以实现精准的肺段切除。

肿瘤相关巨噬细胞(tumor-associated macrophages,TAMs)具有极高的可塑性,是肿瘤微环境(tumor microenvironment,TME)中含量最丰富的免疫细胞。各种TME成分(如细胞因子、趋化因子以及外泌体等)将TAMs招募到肿瘤区域内。随后,这些环境因子把TAMs诱导为抗肿瘤状态(M1样)或促肿瘤状态(M2样)之间的某一极化状态。另外,TAMs的极化过程是连续的,并且会随着肿瘤恶性进展而逐渐地朝向M2样状态,构成了一个有利于肿瘤生长和转移的正反馈环。因此,深入研究影响TAMs极化的各种因素和机制,有助于研发一种新的且可以与其他免疫治疗相结合的肺癌治疗策略。在既往的研究中已发现了许多可以促进TAMs的M2极化的分子和通路。然而,肿瘤细胞、间质细胞和TAMs之间这种复杂的串扰的潜在机制仍然难以研究清楚。在这篇综述中我们总结了促进TAMs向M2表型极化的各种因素,并进一步探讨了相关的分子机制。
