Dear Editor, Phenotypic drug discovery, which observes compound effects on physiology,has given way to targeting specific molecules, but has revived by using modern methods to find drugs based on therapeutic outcomes in disease models(Vincent et al., 2022). Osteoarthritis(OA) is a prevalent chronic joint disorder, primarily affecting knee joints, with osteoclast activation due to low-grade inflammation resulting in increased bone resorption and structural changes in the joint(Katz et al.,2021).

在进一步全面深化改革的时代背景下,探讨社会创新在健全人口发展支持和服务体系中的作用显得尤为关键。由于人口新国情与治理现代化之间的限度,中国人口治理的社会创新始终面临一系列挑战。中华人民共和国成立以来,中国人口治理的创新实践从工具主义导向的偶发性举措创新,到市场驱动下的政策形式创新,再到风险叠加背景下的工具理性创新,最终发展至人口国情下的实质性社会创新。通过构建一个涵盖“横向协调、纵向协同、长远规划”的三维模型,重新建立健全人口发展支撑和服务体系的理论解释框架。该框架的主旨内涵是国家治理的社会创新,要求从整体视角审视人口治理的现代化进程,促进国家战略转向为社会行动。即健全人口发展支持和服务体系在未来实践中,将进一步拓展为“发展性—社会包容”“普惠性—社会投资”“基础性—社会动员”“兜底性—社会保护”的治理现代化矩阵。

The global spin alignment of vector mesons has been observed by the STAR collaboration at the Relativistic Heavy Ion Collider （RHIC） at Brookhaven National Laboratory （BNL）.It provides a unique opportunity to probe the correlation between the polarized quark and antiquark in the strongly coupled quark-gluon plasma （sQGP） produced in relativistic heavy ion collisions,opening a new window to explore the properties of s *** addition,spin alignments of vector mesons have also been observed in other high-energy particle collisions such as e+e-annihilations at high energies where hadron production is dominated by quark fragmentation *** results obtained are quite different from those obtained in heavy ion collisions where quark coalescence/combination mechanism dominates suggesting strong dependence on hadronization *** comprehensive studies in different hadronization processes are *** this article,we present a brief review of theoretical and experimental advances in the study of vector meson’s spin alignments in a variety of high-energy particle collisions,with emphasis on hadronization mechanisms.
