背景与目的囊腔型肺癌作为一种特殊类型的肺癌逐步得到人们的关注,其最常见的病理类型为腺癌。囊腔型肺腺癌的浸润性对诊疗方案的选择和预后至关重要。本研究旨在分析囊腔型肺腺癌临床多特征,探讨其浸润性的独立危险因素并建立风险预测模型。方法回顾性分析2021年1月至2022年7月于南京医科大学第一附属医院胸外科行手术治疗的129例囊腔型肺腺癌患者,根据病理结果分成浸润前组:非典型腺瘤样增生(atypical adenomatous hyperplasia,AAH)、原位腺癌(adenocarcinoma in situ,AIS)、微浸润型腺癌(minimally invasive adenocarcinoma,MIA)与浸润组:浸润性腺癌(invasive adenocarcinoma,IAC)。其中浸润前组47例,男性19例,女性28例,平均年龄(51.23±14.96)岁;浸润组82例,男性60例,女性22例,平均年龄(61.27±11.74)岁。收集两组病例多组临床特征,采用单因素分析、LASSO回归、多因素Logistic回归分析得出囊腔型肺腺癌浸润性的独立危险因素,建立浸润性风险预测模型。结果单因素分析显示年龄、性别、吸烟史、肺气肿、神经元特异性烯醇化酶(neuron-specific enolase,NSE)、囊腔数、病灶直径、囊腔直径、结节直径、实性成分直径、囊壁结节、囊壁光滑程度、囊腔形状、分叶征、短毛刺征、胸膜牵拉、血管穿行与支气管穿行在囊腔型肺腺癌浸润前组与浸润组间存在统计学差异(P<0.05)。上述变量经LASSO回归降维处理,进一步筛选出的变量包括:年龄、性别、吸烟史、NSE、囊腔数、病灶直径、囊腔直径、囊壁结节、囊壁光滑程度与分叶征,并纳入多因素Logistic回归分析,发现囊壁结节(P=0.035)与分叶征(P=0.001)是囊腔型肺腺癌浸润性的独立危险因素(P<0.05)。建立预测模型如下:P=e^x/(1+e^x),x=-7.927+1.476*囊壁结节+2.407*分叶征,曲线下面积(area under the curve,AUC)为0.950。结论囊壁结节及分叶征为囊腔型肺腺癌浸润性的独立危险因素,对囊腔型肺腺癌的浸润性预测具有一定的指导意义。

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.

BACKGROUND： Cerebrovascular intervention is a medical strategy to diagnose and treat cerehrovascular disease by intravascular intervention techniques. With the continual developments of computer technology, imageology, and angiography, cerebrovascular intervention techniques have developed rapidly. OBJECTIVE： To summarize and to evaluate vascular imaging diagnostic techniques, vascular intra-arterial thrombolysis, vascular intra-arterial angioplasty, and vascular embolization in clinical applications. RETRIEVAL STRATEGY： An online search was conducted in PubMed for English language reports, published from January 2002 to January 2008, containing the key words： intervention therapy, cerebral vascular disease, endovascular intervention and angioplasty. A total of 57 publications were identified. Inclusion criteria： articles about cerebrovascular intervention for cerebrovascular disease; articles published either in high impact factor journals or in recent years. Exclusion criteria： duplicated articles. LITERATURE EVALUATION; 30 articles were identified concerning intravascular intervention techniques and arterial angioplasty. Of those, 7 articles were reviews and 23 were clinical or basic studies. DATA SYNTHESIS： Carotid artery and basilar artery stenosis were important etiological factors for ischemic cerebrovascular disease. The mechanism of stenosis induction included atherosclerotic plaque exfoliation and stenosis could cause hemodynamic changes to induce cerebral infarction. Therefore, the treatment of carotid artery and basilar artery stenosis played a key role in preventing ischemic cerebral infarction. The international organization for subarachnoid hemorrhage aneurysm has conclusively shown that both relative and absolute risk factors of intravascular embolotherapy were reduced compared to those of surgical occlusion, demonstrating the important role of vascular embolization for the treatment of intracranial aneurysm. Endovascular stents were placed into the

Progress in Natural Science:Materials International 2005年第11期15卷 1044-1049页

作者： PENG Ke, YANG xinfeng and xu Boling (State Key Laboratory of Modern Acoustics, Institute of Acoustics, Nanjing University, Nanjing 210093, China) State Key Laboratory of Modern Acoustics Institute of Acoustics Nanjing University Nanjing 210093 China

For communication in extremely noisy environments, close-talking microphone arrays are useful. Differential microphone array systems possessing excellent nearfield directivity and strong farfield-noise reduction capability are very suitable for close-talking situations. In order to improve the focusing effect at the desired bearing in the nearfield, we propose a novel self-steering system of close-talking arrays with the first-order differential sub-arrays in this paper. Calculations of directivity patterns and directivity factors show that when a kind of optimized beamforming technique is adopted even small arrays with a focusing configuration will exhibit a satisfactory nearfield directivity which is electronically steerable within a specific range. The superiority of the proposed array system is verified by experiments with real acoustic data.

关键词： close-talking array differential array self-steering directivity factor.
