There is an increasing need to introduce socially interactive robots as a means of assistance in autism spectrum disorder(ASD) treatment and rehabilitation, to improve the effectiveness of rehabilitation training and the diversification of treatment, and to alleviate the shortage of medical personnel in China's Mainland and other places in the world. In this preliminary clinical study, three different socially interactive robots with different appearances and functionalities were tested in therapy-like settings in four different rehabilitation facilities/institutions in Shenzhen, China. Seventy-four participants, including 52 children with ASD, whose processes of interacting with robots were recorded by three different cameras, all received a single-session three-robot intervention. Data were collected from not only the videos recorded, but also the questionnaires filled mostly by parents of the participants. Some insights from the preliminary results were obtained. These can contribute to the research on physical robo it design and evaluations on robots in therapy-like settings. First, when doing physical robot design, some preferential focus should be on aspects of appearances and functionalities. Second, attention analysis using algorithms such as estimation of the directions of gaze and head posture of a child in the video clips can be adopted to quantitatively measure the prosocial behaviors and actions(e.g., attention shifting from one particular robot to other robots) of the children. Third, observing and calculating the frequency of the time children spend on exploring/playing with the robots in the video clips can be adopted to qualitatively analyze such behaviors and actions. Limitations of the present study are also presented.

Background Since the size of ischemic myocardium is closely related with both global and regional function of the myocardium, it is of great significance to measure the size of ischemic myocardium with non-invasive methods. Methods Eleven mongrel dogs were subjected to occlusion of the left anterior descending coronary artery for acute ischemia. Strain rate imaging had M-mode of strain-rate （CAMM） curve pointed from the basal segment of the anterior wall to the basal segment of the inferior wall to detect the border of ischemia size. The strain rate （SR） defined the cut-off value of ischemic myocardium in a two-chamber apical view, and marked by the anterior and inferior wall on two-dimensional images respectively. Along the endocardium and epicardium, the ischemic size was curved on two-dimensional images by the trackball method and then compared with the pathologically ischemic size. And then longitudinal strain rates were compared in the cut-off value, adjacent non-ischemic and ischemic segments at which the cut-off point was defined by changing the curve M-mode of strain rate after ischemia. Results Linear correlation existed between pathology and strain rate ischemic size （r=0.884, P 〈0.001）. The SR parameters were lower in ischemia and cut-off point than in non-ischemic segments. The peak SRs of systole （SSR）, early diastole （EsR）, late diastole （ASR）, strain during ejection time （εet）, and the maximum length change during the entire heart cycle （Emax） in ischemic segments lowered （P〈0.05）. Time to onset of regional relaxation （TR） was prolonged （P=0.012）. Conclusion SR imaging can accurately assess the size of ischemic myocardium. Chin Med J 2009; 122（2）： 193-198

The airwave effect greatly influences the observational data from controlledsource electromagnetic exploration in shallow seas, which obscures the abnormal effects generated by exploration targets and, hence, affects the accuracy of the late exploration data interpretation. In this study, we propose a method to separate the main part from the anomalous field of marine controlled-source electromagnetic method （MCSEM） data based on Stratton-Chu integral transforms to eliminate the airwave effect, which dominates observed electromagnetic （EM） response in shallow seawater. This method of separating the main part from the anomalous field is a type of finite impulse response filter based on a discrete data set. Theoretical analysis proved that the method is stable and able to effectively depress noise. A numerical test indicated that the method could successfully eliminate the airwave effect from the observed EM signals generated by an air water interface and a seawater layer. This technique is applicable for seawater models with either flat or rough seabeds.

目的:探讨顺阿曲库铵不同给药方式联合丙泊酚在腹腔镜手术中的应用效果及对肌肉松弛和肌肉松弛恢复的影响。方法:选取我院2021年1月到2023年11月收治的120例腹腔镜手术患者,分为间断性给药组与一次性给药组,各组均为60例。所有患者进入手术室后采取2 mg/kg丙泊酚、0.4μg/kg舒芬太尼、0.5μg/kg右美托咪定进行麻醉诱导。间断性给药组每隔2 h静脉注射顺阿曲库铵一次,剂量为0.1 mg/kg。一次性给药组采取单次0.1 mg/kg静脉注射顺阿曲库铵进行诱导肌松,并依照T_(1)颤搐抑制值判断肌松效应,T_(1)=12%,当T_(1)>12%时静脉注射顺阿曲库0.03 mg/kg。对比两组患者顺阿曲库铵用药量、肌松有效时间、肌松维持时间、T_(1)最大抑制、肌松起效时间,入室时的基础值(T_(1)),手术开始即刻(T_(2)),手术开始后20 min(T_(3)),手术结束即刻(T_(4))生命体征变化,术后肌肉松弛恢复情况以及不良反应发生率。结果:两组患者肌松维持时间、T_(1)最大抑制程序、肌松起效时间对比无明显差异(P>0.05),一次性给药组患者顺阿曲库铵用药量低于间断性给药组,肌松有效时间高于间断性给药组(P0.05);一次性给药组患者TOFr 0.90、TOFr 0.80、TOFr 0.75、TOFr 0.25及拔管时间明显低于间断性给药组(P<0.05);一次性给药组心动过缓、皮疹、支气管痉挛、低血压等不良反应发生率明显低于间断性给药组(P<0.05)。结论:在腹腔镜手术中采取间断性给药组及一次性给药顺阿曲库铵对患者术中生命体征、肌松维持时间及肌松效果并无明显影响,但采取一次性给药,并以T_(1)颤搐抑制值判断肌松效应进行给药可减少顺阿曲库铵给药剂量,促进术后肌肉松弛恢复,且安全性高。
