| 1 | Painful intervertebral disc degeneration and inflammation:from laboratory evidence to clinical interventions显示文摘Low back pain(LBP),as a leading cause of disability,is a common musculoskeletal disorder that results in major social and economic burdens.Recent research has identified inflammation and related signaling pathways as important factors in the onset and progression of disc degeneration,a significant contributor to LBP.Inflammatory mediators also play an indispensable role in discogenic LBP.The suppression of LBP is a primary goal of clinical practice but has not received enough attention in disc research studies.Here,an overview of the advances in inflammation-related pain in disc degeneration is provided,with a discussion on the role of inflammation in IVD degeneration and pain induction.Puncture models,mechanical models,and spontaneous models as the main animal models to study painful disc degeneration are discussed,and the underlying signaling pathways are summarized.Furthermore,potential drug candidates,either under laboratory investigation or undergoing clinical trials,to suppress discogenic LBP by eliminating inflammation are explored.We hope to attract more research interest to address inflammation and pain in IDD and contribute to promoting more translational research. | Feng-Juan Lyu Haowen Cui Hehai Pan Kenneth MC Cheung Xu Cao James C.Iatridis Zhaomin Zheng | 2021 | Bone Research2021，9，1： | 24 |
| 2 | 水稻质核互作雄性不育系的微效恢复基因定位和排除方法研究显示文摘以232个协青早A/B456///协青早A/B456∥B456植株组成的分离群体为材料,调查花粉可育率和自交结实率,并采用121个在染色体上分布比较均匀的SSR多态性标记进行QTL检测。发现22个SSR标记分别与10个花粉育性位点连锁,分布于第2,5,6,8,10,12染色体上;28个标记分别与16个小穗育性位点连锁,分布于第1,2,4,5,6,8,10和11染色体上;13个标记同时与花粉育性和小穗育性连锁,小穗育性与花粉育性QTL差异是花粉可育度和自交结实率不平行性的遗传基础。各可育位点对花粉育性和小穗育性的提高效应比较小,为微效基因,但每个花粉育性位点的存在都可导致不育系败育不彻底。协青早A中发现1个花粉可育位点Pf5-1,与分子标记Bm55和Rm13紧密连锁,进行分子标记辅助选择,可能排除协青早A的微效恢复基因(可育位点),达到完全不育。协青早A存在8个小穗育性位点,能够提高自交结实率,有助于杂种F1结实率的提高,有利于提高不育系的可恢复性。多数微效恢复基因显示为部分隐性或隐性,是水稻质核互作雄性不育系选育难的重要原因。采用不育系/拟用亲本∥保持系/拟用亲本的方式,观察杂种育性分离,可对拟用亲本的微效恢复基因有所了解,用保持系/部分保持系∥保持系的方式可提高微效恢复基因排除的效率。 | 李新奇 Xu Yun-bi Xiao Jin-hua 袁隆平 Susan Mc Couch | 2010 | 杂交水稻2010，，2： | 3 |
