土地是人类赖以生存的重要资源,在受气候变化影响的同时其状况变化也在气候系统中起着关键作用。IPCC最新发布的气候变化与土地特别报告(SRCCL)系统反映了关于荒漠化、土地退化、可持续土地管理、粮食安全和陆地生态系统碳通量方面的最新科学认知,并探讨了如何进行更加可持续性的土地利用和管理以应对与土地相关的气候变化问题。文中从极端事件变化及其影响的角度,结合SRCCL与其他相关文献,予以分析和总结。结果表明,在全球变暖的背景下,极端天气气候事件的变化已经并将继续影响荒漠化和土地退化进程并对粮食安全造成冲击;而土地对气候系统的反馈作用,又会加剧气候变化并提高极端事件发生的概率和严重程度。面对气候变化尤其是极端事件给土地带来的巨大压力,必须坚持可持续的土地管理,通过减少包括土地和粮食系统在内的所有行业的排放,才有可能实现到21世纪末将全球平均升温控制在相对工业化前水平2℃以内的目标,以减轻气候变化对土地和粮食系统的负面影响。

利用国际耦合模式比较计划第六阶段(CMIP6)中18个地球系统模式总初级生产力(GPP)模拟数据,基于传统的多模式集合平均(MME)和可靠集合平均方法(REA),在4个未来情景(SSP1-2.6,SSP2-4.5,SSP3-7.0和SSP5-8.5)下预估了21世纪全球陆地生态系统GPP的变化量,并分析了GPP变化的驱动因子。研究结果表明:在4个未来情景下,基于REA方法预估的全球陆地生态系统年GPP在未来时期(2068—2100年)比历史时期(1982—2014年)分别增长了(14.85±3.32)、(28.43±4.97)、(37.66±7.61)和(45.89±9.21)PgC,其增量大小和不确定性都明显低于MME方法。在4个情景下,大气CO2浓度增长对GPP变化的贡献最大,基于REA方法计算的贡献占比分别为140%、137%、115%和75%;除SSP5-8.5(24%)外,其他情景下升温均导致全球陆地生态系统GPP降低(-42%、-37%、-16%),部分抵消了CO2施肥效应的正面贡献。温度的影响存在纬度差异:升温在低纬度地区对GPP有负向贡献,在中高纬度地区为正向贡献。降水和辐射变化对GPP变化的贡献相对较小。

目的报告1例中枢性性早熟(central precocious puberty, CPP)女性患儿同患分泌绒毛膜促性腺激素(HCG)的颅内生殖细胞肿瘤(intracranial germ cell tumor, IGCT)资料,为临床CPP的精准诊治提供理论指导。方法总结2020年12月首次就诊于中山大学附属第一医院的1例CPP同患分泌HCG的IGCT女性患儿临床资料,并进行文献复习。结果该例患儿7岁3月龄时出现乳房发育伴生长加速;8岁2月龄于当地诊断CPP,同时发现血β-HCG升高(56.45~20.70 IU/L);8岁9月龄于中山大学附属第一医院就诊示血和脑脊液β-HCG均升高(分别为40.03 IU/L,103.22 IU/L)、甲胎蛋白(AFP)正常。经头颅鞍区脊髓核磁共振成像(MRI)、头颅CT、胸腺CT/MRI、腹部/盆腔B超等检查,确诊为分泌HCG的颅内非生殖细胞瘤性生殖细胞肿瘤(右侧基底节豆状核)、中枢性性早熟、松果体囊肿。予联合化疗连同促性腺激素释放激素(GnRHa)治疗CPP,后化疗不敏感,转脑科医院治疗,予松果体病变手术病理为中枢神经细胞瘤。结论该例CPP女性患儿同患分泌HCG的IGCT为国际首例报告;其CPP的发生与该肿瘤分泌的HCG无关,与该肿瘤和松果体病变导致的中枢神经系统病变可能有关;血β-HCG及AFP检测应纳入性早熟的诊断流程的基本筛查项目。女性CPP(甚至>6岁发病)即使无中枢神经系统异常临床表现,头颅(垂体)MRI/CT检查也是必要的。

Studying molecular recognition in aqueous environments is crucial for understanding biological processes. Herein, we present a series of N-doped endo-functionalized anthracene-based cavities by introducing inward-directed pyridine units. The subtle modifications can significantly affect the binding properties of these receptors, which is similar to the mutations in biological systems. Combining theoretical calculations and molecular recognition experiments demonstrated that these “mutations” have an impact on the hydrophobicity and charge distribution of the hosts, consequently significantly influencing molecular *** is crucial for understanding the intricate mechanisms of molecular-level interactions in biological receptors.
