道德情感是品德现实化的动力因素,是考察儿童知行统一性的关键点。基于2016、2019、2022年中国儿童道德发展的大样本整体动态数据(77953,77367,79914),采用回归分析、夏普里值分解发现中国儿童道德情感的发展:(1)类型不均衡,同情心表现需要关注;(2)水平随年龄的增高呈现先增高后降低的发展趋势,10岁为儿童道德情感发展的关键点;(3)存在性别和城乡区域的结构差异;(4)按因素影响强度呈现独特的生态系统逻辑,从高到低排列为“个体-学校-社会支持-家庭”;生活满意度、了解儿童的人、学校和家庭心理环境是高影响因素;不同因素对不同性别和学段儿童的道德情感发展影响存在差异。由上发现提出,中国儿童道德情感培育要重视道德情感类型的发展失衡、群体发展的差异和关键影响因素,优化儿童道德情感发展的生态系统,抓住发展的关键期,进一步明确教育的侧重点,提升针对性和时效性。

Journal of Systems Engineering and Electronics 2009年第1期20卷 141-145页

作者： Yang Yong'an Feng Zuren sun Linyan Tan Wei Xi'an Jiaotong Univ. Xi'an 710049 P. R. China Xi'an Satellite Control Center Xi'an 710043 P. R. China

This article analyzes the shift factors of the descending node local time for sun-synchronous satellites and proposes a shift control method to keep the local time shift within an allowance range. It is found that the satellite orbit design and the orbit injection deviation are the causes for the initial shift velocity, whereas the atmospheric drag and the sun gravitational perturbation produce the shift acceleration. To deal with these shift factors, a shift control method is put forward, through such methods as orbit variation design, orbit altitude, and inclination keeping control. The simulation experiment and practical application have proved the effectiveness of this control method.

背景:常见的退行性骨骼疾病,如骨关节炎、骨质疏松症和椎间盘退变,其具体的发病分子机制目前尚未明确,可能涉及内质网应激。目前,关于内质网应激在这些常见骨骼疾病发病机制中的系统作用和相关治疗进展的研究较为有限。目的:综述内质网应激在常见的退行性骨骼疾病中的作用,深入探讨这些疾病的分子机制并提供新的防治思路和视角。方法:检索2000-2024年相关文献,以“内质网应激,骨骼疾病,未折叠蛋白反应,骨关节炎,骨质疏松症,椎间盘退变,自噬,凋亡,铁死亡,焦亡”为中文检索词检索中国知网、万方、维普数据库;以“endoplasmic reticulum stress,bone disease,unfolded protein response,osteoarthritis,osteoporosis,intervertebral disc degeneration,autophagy,apoptosis,ferroptosis,pyroptosis”为英文检索词检索PubMed、Web of Science数据库。排除重复和较陈旧的文献,共115篇文献符合纳入标准。结果与结论:①内质网应激在细胞生理调节中具有双重效应。轻度的内质网应激有助于促进成骨分化和细胞外基质合成,然而持续过度的内质网应激则会导致细胞死亡。②内质网应激诱导的细胞自噬、凋亡等与骨关节炎、骨质疏松症、椎间盘退变密切相关。③衰老、药物不良反应、代谢紊乱、钙平衡失调、不良生活习惯等多种原因可导致内质网应激的长期激活,从而引起骨重塑紊乱、软骨损伤、髓核细胞死亡等病理表现,最终导致骨关节炎、骨质疏松和椎间盘退变的发生。④对引发内质网应激的相关机制进行干预,有望在预防和治疗骨关节炎、骨质疏松症和椎间盘退变等常见退行性骨病方面发挥作用。

Schwann cell transplantation is considered one of the most promising cell-based therapy to repair injured spinal cord due to its unique growth-promoting and myelin-forming properties.A the Food and Drug Administration-approved Phase I clinical trial has been conducted to evaluate the safety of transplanted human autologous Schwann cells to treat patients with spinal cord injury.A major challenge for Schwann cell transplantation is that grafted Schwann cells are confined within the lesion cavity,and they do not migrate into the host environment due to the inhibitory barrier formed by injury-induced glial scar,thus limiting axonal reentry into the host spinal *** we introduce a combinatorial strategy by suppressing the inhibitory extracellular environment with injection of lentivirus-mediated transfection of chondroitinase ABC gene at the rostral and caudal borders of the lesion site and simultaneously leveraging the repair capacity of transplanted Schwann cells in adult rats following a mid-thoracic contusive spinal cord *** report that when the glial scar was degraded by chondroitinase ABC at the rostral and caudal lesion borders,Schwann cells migrated for considerable distances in both rostral and caudal *** Schwann cell migration led to enhanced axonal regrowth,including the serotonergic and dopaminergic axons originating from supraspinal regions,and promoted recovery of locomotor and urinary bladder ***,the Schwann cell survival and axonal regrowth persisted up to 6 months after the injury,even when treatment was delayed for 3 months to mimic chronic spinal cord *** findings collectively show promising evidence for a combinatorial strategy with chondroitinase ABC and Schwann cells in promoting remodeling and recovery of function following spinal cord injury.
