The Research of Dual Class Share Structure from the Perspective of Corporate Governance

股权结构是公司治理项下的重要内容，其中股东投票权的配置和实现方式更是对股东权益的保障、公司经营管理有着至关重要的作用。在美国，双层股权结构是公司治理创新实践与发行不同投票权股份相衔接而产生的制度安排，体现了更高程度的公司自治。相较之下，我国立法与实践在股权结构的选择上，仍坚持一股一权的传统模式，并无允许股份公司设立双层股权结构的规定及制度保障。为此，本文将采用比较研究、实证分析、文献研究的方法，对双层股权结构之于公司治理的合法性与合理性进行深入探析。第一部分，解析双层股权结构之内涵，辨析其与同股同权、优先股制度之区别，并分析其适用环境。第二部分，以公司法理论如代理理论、企业契约理论为出发点，论...Share structure is an important issue of corporate governance.

超声引导浅层胸骨旁肋间平面阻滞对胸骨切开心脏手术患者术后恢复质量的影响

目的探究超声引导浅层胸骨旁肋间平面阻滞对胸骨切开心脏手术患者术后恢复质量和镇痛效果的影响。方法本研究共纳入64例胸骨切开心脏手术患者，随机分为接受浅层胸骨旁肋间平面阻滞使用罗哌卡因（罗哌卡因组）或生理盐水（生理盐水组）两组。主要研究指标为患者术后24 h恢复质量评分（QoR-15评分），其次为术后24 h疼痛评分和阿片药物使用情况。结果与生理盐水组比较，罗哌卡因组术后24 h QoR-15评分显著提高［（89.60±13.24） vs （81.18±12.78）， P=0.012］，静息数字疼痛评分显著降低［（3.03±0.72） vs （4.26±0.93）， P<0.001］，咳嗽数字疼痛评分显著降低［（4.40±0.89） vs （5.44±1.05）， P<0.001］。同时，罗哌卡因组患者术后24 h阿片药物使用总量明显减少［14.15 （4.95～30.00） mg vs 40.50 （19.25～68.18） mg， P=0.002］，补救镇痛需求亦明显减少［0.00 （0.00～0.00）mg vs 0.00 （0.00～100.00） mg， P=0.007］。结论超声引导浅层胸骨旁肋间平面阻滞可通过提升术后镇痛效果及减少阿片药物使用量，提高胸骨切开心脏手术患者术后24 h的总体恢复质量，利于术后早期康复

在不同应激状态下MDM2 基因对Jurkat 细胞的作用

【目的】探讨MDM2 基因在不同应激状态下对T 细胞性白血病细胞株Jurkat 增殖、凋亡和基因表 达的影响。【方法】采用RNA 干扰下调白血病细胞株Jurkat MDM2 基因表达后, 用Western blot、流式细胞术等 方法检测Jurkat 细胞在不同应激状态下的变化。【结果】无应激状态下, MDM2 基因表达下降后, Jurkat 细胞增 殖减慢, 细胞周期表现一定程度的G1-S 阻滞; E2F1 表达明显降低超过78%, p65 表达下调超过58%; 细胞损 伤后, MDM2 表达下调可导致细胞损伤修复减慢, 增强紫外线和甲氨喋呤诱导凋亡作用, 导致甲氨喋呤作用下 Rb 和Bax 基因的表达相对增加。【结论】在不同应激状态下, MDM2 基因表达下降广泛影响Jurkat 细胞的增殖、 凋亡和基因表达等生物学特性, 提示MDM2 基因有可能作为T 细胞性白血病治疗的潜在新靶点

高龄经产妇剖宫产术中出血风险因素分析

目的分析高龄经产妇剖宫产术中出血风险因素，为防治剖宫产术中出血提供理论依据。方法回顾分析2015年1月至2019年12月在中山大学附属第一医院高龄经产妇剖宫产1 838例临床资料。根据产妇术中出血量是否≥500 mL，分为出血组与常规出血组，分析产妇基本资料、术中因素、胎盘因素等各类因素与术中出血相关性，通过多因素二分类Logistic回归分析得出独立风险因素。结果Logistic回归分析显示，手术时间［OR=1.069，95% CI为（1.050， 1.089），P<0.001］、胎盘娩出方式［OR=3.131，95%CI为（1.259， 7.782）， P=0.014］、胎儿窘迫［OR=4.727，95%CI为（1.191， 18.763），P=0.027］、手术级别［OR=21.494，95%CI为（6.031， 76.611），P<0.001］、麻醉方式［OR=2.904，95%CI为（1.158， 7.281），P=0.023］和宫缩乏力［OR=7.255，95%CI为（4.413， 11.927），P<0.001］为术中出血独立风险因素。结论手术时间、胎儿窘迫、手术级别、麻醉方式、宫缩乏力、胎盘娩出方式是高龄经产妇剖宫产术中出血主要影响因素，临床应针对以上风险因素，制定相应措施，以减低剖宫产术中出血风险

[[alternative]]Increasing Purchasing Behaviors for Elementary Students With Autism UsingAssistive Technology

[[abstract]]The present study aimed to investigate the effects of using assistive technology to assist teaching on purchasing behaviors for elementary students with moderate to low functioning autism. A design of single-subject multiple probe across subjects （from baseline, intervention to generalization phases design）was adopted. Meanwhile the interview with the teachers and students of the students was inquired. Their point of view about the effect of assistive technology will be taken into consideration to assist teaching on purchasing behaviors. As regards the subjects, three boy students with autism （two in the fourth grade and one in the sixth grade）were chosen. The independent variable was “assistive technology” including purchasing activity of videodisc, the photographs of purchasing activity procedure and AAC. The dependent variable was “purchasing behaviors” including the subjects of purchasing and orally describing the purchasing action skills. Data were analyzed by visual analysis method. The results are summarized as follows： 1. After teaching, the students with moderate to low functioning autism of purchasing skills demonstrated amazing progress, and three students all achieve objective standard and could generalize to other conditions 2. After teaching, the students could use oral expression to describe the purchasing actions skills. Students both B and C achieved objective standard and could generalize to other conditions. Student A failed to achieve the standard required because he was not incapable of expressing the longer length of the sentences and clearly understanding some vocabulary. Nevertheless, he was able to generalize to other conditions within his limited ability. 3. The feedback of the subjects’ parents and teachers indicated that the effects on assisitive technology to assist teaching on purchasing behavior for the three students were positive. Also the progress of purchasing behaviors promoted students’ fine motor skills, courage, volume, and improved such problem behaviors as restlessness and the murmuring to himself. After the end of the study, both teachers and parents continue conducting about the training of purchasing behaviors. According to the above mentioned results, discussions, and limitations of this study, some recommendations for the teaching and further studies were made.
