目的探讨单孔胸腔镜能否成为肺隔离症有效的治疗方式。方法回顾性分析上海市肺科医院胸外科2010年2月—2021年6月诊断为肺隔离症并行手术切除患者的临床资料。根据手术方式将患者分为胸腔镜组和开胸组,对两组手术时间、术中出血量、住院时间及术后并发症发生率等进行分析,并对胸腔镜组进行亚组(单孔胸腔镜组和多孔胸腔镜组)分析。结果纳入患者131例,其中男62例、女69例,平均年龄(39.3±13.2)岁。胸腔镜组103例,开胸组28例。左下肺隔离症104例,右下肺隔离症26例,双下肺隔离症1例。咳嗽(88例,67.2%)为主要临床症状。术前119例行胸部增强CT检查确诊。胸腔镜组和开胸组手术时间差异无统计学意义(P=0.717),而胸腔镜组术中出血量、术后住院时间、术后并发症发生率比开胸组更有优势,差异有统计学意义(P<0.05)。另外在亚组分析中单孔胸腔镜组与多孔胸腔镜组术中中转开胸的比例分别为11.8%和13.5%。同时单孔胸腔镜组术中出血量比多孔胸腔镜组少,术后并发症发生率比多孔胸腔镜组低,且手术时间、术后住院时间比多孔胸腔镜组短,差异有统计学意义(P<0.05)。结论为提高肺隔离症术前诊断准确率,胸部增强CT可作为成人疑似病例(尤其是下叶肺出现囊实性或实性病变)的首选检查方法。对于肺隔离症,单孔胸腔镜是一种安全有效的治疗方式,值得推广。

This review summarizes the mechanism and performance of metal oxide based resistive switching memory. The origin of resistive switching （RS） behavior can be roughly classified into the conducting filament type and the interface type. Here, we adopt the filament type to study the metal oxide based resistive switch- ing memory, which considers the migration of metallic cations and oxygen vacancies, as well as discuss two main mechanisms including the electrochemical metallization effect （ECM） and valence change memory effect （VCM）. At the light of the influence of the electrode materials and switching layers on the RS char- acteristics, an overview has also been given on the performance parameters including the uniformity, endurance, the retention, and the multi-layer storage. Especially, we mentioned ITO （indium tin oxide） electrode and discussed the novel RS characteristics related with ITO. Finally, the challenges resistive random access memory （RRAM） device is facing, as well as the future development trend, are expressed.

Highly textured Ni nanowire arrays were fabricated into anodic aluminum oxide （AAO） templates by pulse DC electrodeposi- tion. The applied voltage and pH value of electrolytes were found strongly affecting the microstrucmre and magnetic proper ties of Ni nanowire arrays. Low applied potential and pH value both prefer to form polycrystalline fcc Ni nanowires. Increas- ing the applied potential or pH value favors the Ni [220] texture and even eventually forms the [220] oriented single crystal Ni wires, while exorbitant potential and pH value will conversely weaken the texture of nanowires. The magnetic properties of Ni wires are closely related to the microstructure of Ni nanowire arrays and large coercivities more than 1000 Oe were achieved at single crystalline Ni nanowire arrays. The mechanisms for the effect of applied potential and pH value on the grain size, tex- ture and magnetic properties of Ni nanowire arrays have been discussed.

Background: Pulmonary embolism (PE) is a severe and acute cardiovascular syndrome with high mortality among patients with autoimmune inflammatory rheumatic diseases (AIIRDs). Accurate prediction and timely intervention play a pivotal role in enhancing survival rates. However, there is a notable scarcity of practical early prediction and risk assessment systems of PE in patients with ***: In the training cohort, 60 AIIRD with PE cases and 180 age-, gender-, and disease-matched AIIRD non-PE cases were identified from 7254 AIIRD cases in Tongji Hospital from 2014 to 2022. Univariable logistic regression (LR) and least absolute shrinkage and selection operator (LASSO) were used to select the clinical features for further training with machine learning (ML) methods, including random forest (RF), support vector machines (SVM), neural network (NN), logistic regression (LR), gradient boosted decision tree (GBDT), classification and regression trees (CART), and C5.0 models. The performances of these models were subsequently validated using a multicenter validation ***: In the training cohort, 24 and 13 clinical features were selected by univariable LR and LASSO strategies, respectively. The five ML models (RF, SVM, NN, LR, and GBDT) showed promising performances, with an area under the receiver operating characteristic (ROC) curve (AUC) of 0.962-1.000 in the training cohort and 0.969-0.999 in the validation cohort. CART and C5.0 models achieved AUCs of 0.850 and 0.932, respectively, in the training cohort. Using D-dimer as a pre-screening index, the refined C5.0 model achieved an AUC exceeding 0.948 in the training cohort and an AUC above 0.925 in the validation cohort. These results markedly outperformed the use of D-dimer levels ***: ML-based models are proven to be precise for predicting the onset of PE in patients with AIIRD exhibiting clinical suspicion of *** Registration: ***: ChiCTR2200059599.
