在真核生物中,mRNA翻译过程包括起始、延伸和终止。其中,翻译的起始阶段最为重要且复杂,它决定了mRNA能否被有效翻译成蛋白质。根据翻译起始机制的不同,真核生物mRNA翻译可以分为传统的帽-依赖性翻译和替代机制帽-非依赖性翻译。当外部环境的刺激或细胞自身的改变使细胞处于应激状态时,传统的帽-依赖性翻译被抑制或下调,替代机制帽-非依赖性翻译得以启动,以保证翻译的顺利进行。真核生物在应激状态下为了维持蛋白质合成的需求,采用多种翻译起始机制来实现帽-非依赖性翻译。其中较常见的是IRES(internal ribosome entry site)、m6A修饰和CITE(cap-independent translation enhancer)所启动的翻译。这些机制允许核糖体在mRNA的特殊区域内部进行启动,而不依赖于传统的m7G帽结构。通过这些机制,真核生物可以在应激状态下仍然进行蛋白质合成,以满足细胞的需要。本文在总结传统帽-依赖性翻译研究进展基础上,着重介绍IRES、m6A和CITE所启动的帽-非依赖性翻译,为更好地探索细胞应激状态下的翻译机制提供参考,为未来的翻译研究和应用提供更多的思路。

Introduction: Acromioclavicular (AC) joint dislocation is a common shoulder injury, comprising 9% - 12% of shoulder girdle injuries. Optimal management remains challenging, with treatment decisions guided by the Rockwood classification system. Controversies surround grade III injuries, necessitating further classification. Non-operative treatment has shown favorable outcomes, while surgical interventions vary. Anatomical coracoclavicular reconstruction (ACCR) has demonstrated biomechanical advantages over traditional methods. Arthroscopic techniques offer advantages, minimizing deltoid detachment and allowing concurrent pathology identification. This study evaluates the outcomes of arthroscopic-assisted ACCR in chronic AC joint dislocation. Surgical Technique: Arthroscopic-assisted ACCR involves meticulous portal placement, tendon graft harvesting, diagnostic arthroscopy, and coracoid exposure. The clavicle tunnels were made to mimic the conoid and trapezoid ligament positions, using FibreTape#2 loop and Dog Bone Button for correct placement against the coracoid base, and passing the semitendinosus graft through to reconstruct the conoid ligament, reduction done and graft follow through for anatomical reconstruction. Methods: A retrospective cohort study at hospital kuala Lumpur analyzed 35 patients undergoing arthroscopic-assisted ACCR for Rockwood grade III - V AC joint dislocations. Inclusion criteria encompassed trauma ≥ 3 weeks prior, no prior shoulder injuries, and ≥12-month follow-up. Functional and radiological assessments utilized ASES scores and coracoclavicular distances, respectively. Statistical analysis employed descriptive statistics and logistic regression. Results: The mean age was 38.9 years (SD 11.26), and 34 of 35 patients were male. Grade IV injuries were predominant (37.1%). Waiting time for surgery averaged 234.9 days. Functional improvement was substantial postoperatively (ASES: 55.5 to 88.9). Radiological outcomes demonstrated reduced coraco

基于kriging模型的复杂结构可靠性分析结果高度依赖于kriging模型的拟合精度,在构建kriging模型的过程中,不同相关函数和回归函数的选择均会影响模型精度。为解决模型的不确定性对可靠性分析结果的影响,同时兼顾计算效率和精度,基于kriging模型和蒙特卡罗模拟(MCS)方法,提出了一种结合自适应集成策略和主动学习函数的结构可靠度计算方法。该方法考虑kriging模型的建模不确定性,将多种kriging模型组合,构建了一种综合考虑样本点贡献和样本点距离的主动学习函数,通过主动学习函数迭代更新集成kriging模型直至满足收敛条件,最后通过构建的集成kriging模型和MCS方法进行结构可靠性分析。数值算例和工程算例结果验证了所提方法的有效性,该方法与其他主要方法相比稳健性更好,在保证计算精度的同时,计算效率更高。
