Bone marrow edema(BME)is characterized by an accumulation of interstitial fluid within the bone marrow,the cancellous,hematopoietic compartment within bones.[1]BME is divided into two principal categories:idiopathic or primary BME,with an unknown etiology,and secondary BME,which occurs as a result of an identifiable underlying pathology.[2.Although the prevalence of BME is not limited to specific demographic parameters,it shows a predilection for males or individuals assigned male at birth,predominantly aged between the ages of 30 and 60 years,especially in cases of bone marrow edema syndrome(BMES),a rare idiopathic variant.[3]The etiological spectrum of BME is diverse,including oncological entities(such as acute myeloid leukemia and osteosarcoma),degenerative diseases(such as osteoarthritis),infectious processes(osteomyelitis),ischemic conditions(avascular necrosis),metabolic dysfunctions(osteoporosis),inflammatory disorders(rheumatoid arthritis),and traumatic injuries(such as stress fractures).[1,2.Clinically,BME primarily manifests as localized pain,often accompanied by joint effusion and warmth near the affected *** protocols typically include physical examination,serological assays,bone marrow biopsies,dual-energy X-ray absorptiometry(DEXA)scans,magnetic resonance imaging(MRI),and ultrasonography,with computed tomography(CT)scans and radiographs being less effective.

1950年至1951年间,为了改革企业管理制度、激发工人“主人翁”意识,中国共产党在国营企业开展了民主改革。在这场改革中,中共对工人的动员策略逐渐走向成熟:民主改革初期,中共希望以制度改革推动工人自觉形成“主人翁”意识,但并未达到预期效果;在民主团结运动阶段,中共将政治动员手段引入企业,有意识塑造工人的“主人翁”观念,这一尝试取得了显著的成效。上海市委根据上海国营企业的特点采取了相对温和的运动策略,使企业小组管理制度在民主团结运动中实现平稳交替。通过民主改革的探索,中共寻找到以政治动员发动工人的有效方法,对此后国家经济建设与企业管理都产生了深远影响。

企业家精神就是市场活力,是社会创新驱动力。企业家精神条款是落实我国市场体制方略的法律表达,亦是填补《公司法》内在体系的理性价值。新法适用中,应当充分激活企业家精神条款的价值引领功能,避免法律监管规范孤立适用所造成的新一轮利益失衡风险,防止企业家精神条款现实目的发生偏离。企业家精神条款所蕴含的个体主义价值表达要求新《公司法》充分发挥市场在资源配置中的决定性作用,强调以商人自治作为公司治理核心。应以企业家精神条款的个体主义价值为引领,对公司法律监管规范作出如下解释适用:其一,缓和董监高及双控人的法律强制监督,回归公司自决和市场引导;其二,对决议不成立情形遵循实质审查标准;其三,对禁止股东权利滥用原则建立更为具化的要件审查标准,从保护弱势股东转向保护被压迫股东。

碱性岩浆对金属成矿和金属矿集区有独特控制作用,因火山—侵入岩序列与金属成矿和岩浆叠加侵入构造系统识别难度大,长期制约了深部勘探和找矿预测。本文以云南东川铁铜金矿集区(元古宙陆缘裂谷盆地)和个旧锡铜钨铯铷多金属矿集区(三叠纪弧后裂谷盆地)为主,采用大比例尺构造岩相学填图新方法,解析研究了碱性岩浆活动有关的火山—侵入岩侵入序列与岩石组合、裂谷盆地演化和岩浆叠加侵入构造系统,揭示了它们与滇东地区铁氧化物铜金型(IOCG)、铜钴-金红石-稀土和锡铜钨铯铷多金属矿叠加成矿内在关系。研究认为:①云南东川铁铜金矿集区内,新太古代末期碱性岩类以方解石钠长岩(2.2.±14 Ma)和碱性铁质苦橄岩(2.2.±77 Ma)为主。新太古界—古元古界小溜口岩组(>2.50Ga)顶部古岩溶风化壳,受中元古代火山喷发—岩浆侵入构造叠加再造形成了特殊单元(独立填图单元,2.50~1.80Ga),它们是铜钴-金红石-稀土矿床的新找矿层位。②在中元古界因民组一段内,铁钠质碱性基性岩、铁钾质粗面岩和铁质碱性辉绿辉长岩等岩石组合形成于因民期火山断陷成盆期。因民组二段和三段是稀矿山式铁铜矿床储矿层位,铁铜矿层下盘铁钾质粗面岩为独居石型稀土成矿层位。在格林威尔造山期碱性钛铁质辉长岩(1097~1047 Ma)-碱性钛铁质闪长岩-碱性二长斑岩等碱性钛铁质侵入岩体,形成了白锡腊深部IOCG矿床和金红石富集成矿。③在个旧三叠纪弧后裂谷盆地内,三叠纪碱性苦橄岩和碱玄岩中形成了Sn-Cu-Zn-Li-Rb-Cs初始富集;在晚白垩世浅色花岗岩叠加成矿作用下,形成了金云母矽卡岩型锡铜钨铯铷矿床。④裂谷盆地内早期碱性岩中初始富集金属与后期富含成矿金属的碱性侵入岩叠加成矿可能是金属超常富集机理。在东川地区岩浆叠加侵入构造内,岩浆热液角砾岩筒对铜钴-金红石-稀土元素叠加富集成矿控制显著;在个旧地区,浅色花岗岩侵入于碱性苦橄岩-碱玄岩中,对金云母矽卡岩型锡铜钨钴铯铷矿床的叠加富集成矿控制显著。
