BACKGROUND This study was designed to investigate the clinical outcomes of enhanced recovery after surgery(ERAS)in the perioperative period in elderly patients with nonsmall cell lung cancer(NSCLC).AIM To investigate the potential enhancement of video-assisted thoracic surgery(VATS)in postoperative recovery in elderly patients with *** We retrospectively analysed the clinical data of 85 elderly NSCLC patients who underwent ERAS(the ERAS group)and 327 elderly NSCLC patients who received routine care(the control group)after VATS at the Department of Thoracic Surgery of Peking University Shenzhen Hospital between May 2015 and April *** propensity score matching of baseline data,we analysed the postoperative stay,total hospital expenses,postoperative 48-h pain score,and postoperative complication rate for the 2 groups of patients who underwent lobectomy or sublobar *** After propensity score matching,ERAS significantly reduced the postoperative hospital stay(6.96±4.16 vs 8.48±4.18 d,P=0.001)and total hospital expenses(48875.27±18437.5 vs 55497.64±21168.63 CNY,P=0.014)and improved the satisfaction score(79.8±7.55 vs 77.35±7.72,P=0.029)relative to those for routine *** significant between-group difference was observed in postoperative 48-h pain score(4.68±1.69 vs 5.28±2.1,P=0.090)or postoperative complication rate(21.2%vs 27.1%,P=0.371).Subgroup analysis showed that ERAS significantly reduced the postoperative hospital stay and total hospital expenses and increased the satisfaction score of patients who underwent lobectomy but not of patients who underwent sublobar *** ERAS effectively reduced the postoperative hospital stay and total hospital expenses and improved the satisfaction score in the perioperative period for elderly NSCLC patients who underwent lobectomy but not for patients who underwent sublobar resection.

Let G be a k-connected graph, and T be a subset of V（G）. If G-T is not connected,then T is said to be a cut-set of G. A k-cut-set T of G is a cut-set of G with │T│=k. Let T bea k-cut-set of a k-connected graph G. If G - T can be partitioned into subgraphs G1 and G2such that │G1│≥ 2, │G2│ 〉 2, then we call T a nontrivial k-cut-set of G. Suppose that G is a（k-1）-connected graph without nontrivial （k - 1）-cut-set. Then we call G a quasi k-connectedgraph. In this paper, we prove that for any integer k ≥ 5, if G is a k-connected graph withoutK4-, then every vertex of G is incident with an edge whose contraction yields a quasi k-connectedgraph, and so there are at least │V（G）│/2 edges of G such that the contraction of every member ofthem results in a quasi k-connected graph.

目的基于CT下胫腓联合腓骨切迹形态学分型及其临床意义。方法根据纳入排除标准分析在骨伤科行踝关节CT检查患者(男性123例,女性102例,均为汉族,年龄18~60岁)的图像资料,按形态学特点对下胫腓联合腓骨切迹进行分型,并测量下胫腓联合腓骨切迹周围的8个距离。结果回顾分析了2013年12月~2022年12月225例患者结果,可将下胫腓联合腓骨切迹分为4型:C形(50.67%)、V形(26.67%)、平坦形(15.11%)、L形(7.56%)。平坦形的切迹前后部夹角(145.56±9.25)°最大(P<0.05),L形切迹前后部夹角(125.07±13.54)°最小(P<0.05);平坦形的切迹深度(3.11±0.83)mm最小(P<0.05),L形的切迹深度(4.47±1.11)mm最大(P<0.05)。左侧切迹后部长度(13.06±3.56)mm、胫腓前间隙(3.83±1.49)mm明显大于右侧(P<0.05);男性切迹后部长度(13.36±3.46)mm、切迹深度(3.93±1.10)mm及胫腓重叠垂直距离(9.10±2.55)mm明显大于女性(P<0.05)。结论通过测量下胫腓联合腓骨切迹相关数据并根据形态将其分为4种类型。平坦形下胫腓联合腓骨切迹更易出现慢性踝关节不稳,在解剖复位时更易发生腓骨前移;而L形和C形切迹的下胫腓联合在解剖复位时更易发生腓骨后移或旋转复位不良。

The dynamical behavior in the cortical brain network of macaque is studied by modeling each cortical area with a subnetwork of interacting excitable neurons. We characterize the system by studying how to perform the transition, which is now topology-dependent, from the active state to that with no activity. This could be a naive model for the wakening and sleeping of a brain-like system, i.e., a multi-component system with two different dynamical behavior.
