文章以矩阵语言框架模型为理论基础,探讨了中文教师在以中文为矩阵语言、英语为嵌入语的教学中,汉—英语码转换的词类特点和语法规则。研究发现:中文教师在课堂进行语码转换时以名词、动词、形容词等实词为主要转码对象,借助英语解释帮助学生理解词汇;中文教师在进行语码转换时基本遵循矩阵语言即汉语的语法规则;综合课语码转换频率高于语法课,新课的语码转换频率高于复习课;教学法越多样,学生年龄越低的课堂,语码转换越多。相关结论对中文教学具有一定启示作用。

Background Neovascular glaucoma is a refractory disease, and difficult to manage. The aim of this study was to evaluate the clinical outcomes of Ahmed glaucoma valve implantation （AGVI） in neovascular glaucoma （NVG） and non- NVG patients. Methods This prospective, non-randomized study included 55 eyes of 55 patients with refractory glaucoma; 27 had NVG （NVG group） and 28 had non-NVG （non-NVG group）. All of the patients underwent AGVI. The NVG group was adjunctively injected with intravitreal ranibizumab/bevacizumab （IVR/IVB） before AGVI. Intraocular pressure （lOP） was the primary outcome measure in this study. Surgical success rate, number of antiglaucoma medications used, best corrected visual acuity （BCVA）, and postoperative complications were analyzed between the groups. Results All of the patients completed the study （follow-up of 12 months）. Kaplan-Meier survival curve analysis indicated that the qualified success rates in the NVG and non-NVG groups at 12 months were 70.5% and 92.9%, respectively; this difference was significant （P=-0.036）. The complete success rates in the NVG and non-NVG groups at 12 months were 66.7% and 89.3%, respectively （P=0.049）. Compared with preoperative examinations, the postoperative mean lOP and use of medications were significantly lower at all follow-up time points in both groups （all P 〈0.05）. There were significant differences in BCVA between the two groups at the 12-month follow-up （X2=9.86, P=0.020）. Cox proportional hazards regression showed NVG as a risk factor for surgical failure （RR=15.08, P=0.033）. Postoperative complications were similar between the two groups. Conclusions AGVI is a safe and effective procedure in refractory glaucoma, but the success rate of surgery was related to the type of refractory glaucoma. The complete and qualified success rates of NVG patient adjunctive anti-vascular endothelial growth factor treatment are still lower than those of non-NVG patients.

In recent years,with the development of artificial intelligence,especially deep learning technology,researches on automatic detection of cerebrovascular diseases on medical images have made tremendous progress and these models are gradually entering into clinical practice.However,because of the complexity and flexibility of the deep learning algorithms,these researches have great variability on model building,validation process,performance description and results interpretation.The lack of a reliable,consistent,standardized design protocol has,to a certain extent,affected the progress of clinical translation and technology development of computer aided detection systems.After reviewing a large number of literatures and extensive discussion with domestic experts,this position paper put forward recommendations of standardized design on the key steps of deep learning-based automatic image detection models for cerebrovascular diseases.With further research and application expansion,this position paper would continue to be updated and gradually extended to evaluate the generalizability and clinical application efficacy of such tools.

Objective To assess the prevalence and risk of coronary artery disease(CAD) in Chinese adults with type 2 diabetes mellitus(T2DM) using electron beam computed tomography(EBCT) and EBCT angiography(EBCTA) . Methods:Ninety-four cases were enrolled in this study including diabetes(n=28) ,impaired glucose tolerance(IGT,n=30) ,coronary heart disease(CHD,n=11) ,and control(n=25) . Cardiac EBCT plain scanning and EBCTA were performed on all of these subjects to evaluate coronary artery calcifica-tion(CAC) scores,and number of segments of stenosed coronary arteries. Both CAC and/or coronary artery stenosis were defined as patients with coronary artery lesions(CAL) . Results CAC scores were not different with the control,diabetes,IGT,or CHD(P>0.05) groups. Compared to control(0.520±1.295) ,more stenosed coronary arteries segments(P<0.05) were detected in diabetes(2.964± 1.915) ,IGT(2.200±2.024) ,and CHD(2.273±1.679) . Number of stenosed artery segments were correlated with age(r=0.215,P=0.019) ,postprandial glucose(r=0.224,P=0.015) ,total cholesterol(r=0.323,P=0.000) ,and duration of diabetes(r=0.208,P=0.004) . The incidences of CAL in diabetes(96.43%) ,IGT(93.33%) ,and CHD(90.91%) was substantially higher than that in normal control(56.00%,P<0.01) . The odds ratio of CAL associated with having diabetes was estimated to be 7.514(95% CI:1.885-63.778) . Conclusions Coronary artery lesions are prevalent in Chinese adults with type 2 diabetes,implying a high CAD risk. EBCTA holds potential in depicting the details of CAL and can be used to track the progression of CAD in diabetes patients.

近红外二区(NIRⅡ, 1000~1700 nm)生物成像作为近年来新生的光学成像技术,相对于传统的近红外一区(NIR Ⅰ,750~900nm)和可见光(Vis,400~750nm)成像,由于其荧光波长更长,生物组织的自发荧光背景更低,光子散射值更低,其组织穿透深度更深,该技术更适合于活体原位成像.本文综述了近红外二区荧光成像技术的发展及其在活体成像方面的应用,总结了各项技术的特点,最后对该研究方向的发展前景进行了展望,指出通过化学材料、光电仪器和多模态技术等多方面的持续发展,有望推动近红外二区活体成像技术的临床转化.
