抗TIGIT单克隆抗体的制备及活性鉴定

目的制备新型抑制剂膜分子TIGIT(T cell immunoglobulin and ITIM domain)的单克隆抗体并鉴定其在心脏移植免疫耐受中的作用.方法用人TIGIT-GST重组蛋白免疫小鼠并制备单克隆抗体,抗体特异性实验检测抗体与TIGIT的结合能力.运用重导向杀伤实验检测TIGIT抗体对NK细胞杀伤P815的作用.通过酶吸收法检测TIGIT活化性抗体对CTLs及CD8 Treg细胞活性的影响.结果成功制备得到一株非活化的抗TIGIT的抗体7M13和一株活化性的抗TIGIT抗体4D9.抗体特异性实验表明抗体7M13和4D9均能与人和小鼠的TIGIT结合.重导向杀伤实验表明该抗体7M13对NK细胞杀伤P815细胞的功能没有显著抑制作用,说明7M13可以与TIGIT结合而不活化TIGIT;而4D9则可以显著抑制NK细胞的杀伤功能.从37例心脏移植患者中分离CTLs及CD8 Treg,采用TIGIT活化性抗体处理对细胞生存能力无显著影响,但可明显抑制CTLs的增殖能力,而对CD8 Treg的增殖能力无显著影响.结论分别成功获得非活化的抗TIGIT抗体7M13和活化性的抗TIGIT抗体4D9,并且4D9可显著抑制NK细胞的杀伤功能.     

Study on the dynamic characteristics of soft soil

Soft soil is a special type of under-consolidated soil widely distributed in coastal areas of China. In recent years, with the rapid development of Tianjin, an increasing number of public and civil buildings have been built on soft soil. Soft soil poses an imperceptible risk to the safety of buildings in the area. This paper statistically analyzes the physical and dynamic properties of soft soil in Tianjin, and gives the corresponding range values. The results are as follows. (1) Except for the liquidity index, there is a certain correlation between other physical properties; (2) analyzed by experiment, the effects of consolidation time, consolidation ratio, and effective confining pressure on the dynamic shear modulus ratio and damping ratio of soft soil are given. (3) A model of the relationship between shear wave velocity and burial depth of clay and silty clay in the region is given. (4) The influence of different kinetic parameters on the design response spectrum is analyzed. The work described in this article is valuable for workers engaged in soft soil research.

Comparison of parent report and direct assessment of child skills in toddlers

BackgroundThere are unique challenges associated with measuring development in early childhood. Two primary sources of information are used: parent report and direct assessment. Each approach has strengths and weaknesses, particularly when used to identify and diagnose developmental delays. The present study aimed to evaluate consistency between parent report and direct assessment of child skills in toddlers with and without Autism Spectrum Disorder (ASD) across receptive language, expressive language, and fine motor domains.Method109 children were evaluated at an average age of two years; data on child skills were collected via parent report and direct assessment. Children were classified into three groups (i.e., ASD, Other Developmental Disorder, or Typical Development) based on DSM-IV-TR diagnosis. Mixed design ANOVAs, with data source as a within subjects factor and diagnostic group as a between subjects factor, were used to assess agreement. Chi square tests of agreement were then used to examine correspondence at the item level.ResultsResults suggested that parent report of language and fine motor skills did not significantly differ from direct assessment, and this finding held across diagnostic groups. Item level analyses revealed that, in most cases of significant disagreement, parents reported a skill as present, but it was not seen on direct testing.ConclusionsResults indicate that parents are generally reliable reporters of child language and fine motor abilities in toddlerhood, even when their children have developmental disorders such as ASD. However, the fullest picture may be obtained by using both parent report and direct assessment.

高校学生的价值理念缺失及其应对策略

近几年来，高校学生的心理问题日益突出，这与他们的价值理念缺失有很大关系。目标缺失、信仰缺失和意义缺失是当代大学生主要的价值理念缺失。确立一种新的目标，树立一种信仰，赋予人生积极的意义，以目标做载体，以信仰当支柱，以意义为归宿，才能走出价值理念缺失的状况，健康快乐地生活和成长。

随访方式对冠心病患者介入治疗预后的影响

目的:探讨不同随访方式对接受冠状动脉介入治疗(PCI)患者预后的影响。方法:将已行PCI的358例冠心病患者,随机分为对照组和观察组。观察组除了给予常规的出院医嘱之外,医生主动为患者安排复诊时间及复诊内容,并监督完成;对照组则仅给予患者出院医嘱,由患者自己安排复诊,医生被动接受患者复诊。一年后随访,观察两组患者的吸烟、体重及血压、血脂、血糖的控制情况,并统计主要不良心血管事件(包括再发急性冠脉综合征、血管重建、与心脏有关的猝死)的发生率。结果:与对照组比较,观察组吸烟、体重、血脂、血压、血糖控制好(P<0.01),发生主要不良心血管事件明显减少(P<0.01)。结论:随访方式改变有利于PCI治疗后冠心病患者的心血管危险因素的控制,明显降低了主要不良心血管事件。建议随访模式转变为医生主动为患者服务,及早发现问题,早期处理。
