Investigating spatiotemporal changes in crustal stress associated with major earthquakes has implications for understanding seismogenic ***,in individual earthquake cases,the characteristics of the stress after it reaches its maximum value are rarely *** this study,we use the 2021 M_S6.4 Yangbi earthquake in Yunnan,China and events of magnitudes M_L≥3.0 occurred in the surrounding area in the previous 11 years to investigate the spatiotemporal evolution of apparent *** results indicate that apparent stress began to increase in January 2015 and reached a maximum in January *** stress then remained at a high level until October 2020,after which it declined *** suggest that the stress was in the accumulation stage from January 2015 to January 2020,and entered the meta-instability stage after October *** the meta-instability stage,the zone of decreasing stress expanded continuously and the apparent stress increased around the Yangbi earthquake source *** features are generally consistent with the results of laboratory rock stress *** propose that apparent stress can be a good indicator for determining whether the stress at a specific location has entered the meta-instability stage and may become the epicenter of an impending strong earthquake.

特发性肺纤维化是慢性虚损性肺系疾病,病因不明,证候复杂,病情常迁延不愈。从中医五脏一体观理论探析特发性肺纤维化病机特点可知,该病的发生归结于五脏功能失调,以肺、脾、肾为主轴,兼顾肝、心;其发病的演变规律为肺病传脾,脾虚痰瘀,... 详细信息

特发性肺纤维化是慢性虚损性肺系疾病,病因不明,证候复杂,病情常迁延不愈。从中医五脏一体观理论探析特发性肺纤维化病机特点可知,该病的发生归结于五脏功能失调,以肺、脾、肾为主轴,兼顾肝、心;其发病的演变规律为肺病传脾,脾虚痰瘀,继而肺病及肾,肺肾亏虚,后期累及肝、心。痰、瘀贯穿疾病的始终,是病理产物,亦是致病因素。因此,应从“五脏一体观”理论出发治疗特发性肺纤维化,整体防治,气血同调,以平为期,未病先防,既病防变。

以樱桃常见品种‘雷尼尔’、‘布鲁克斯’、‘雷吉纳’、‘美早’为试材,采用近红外光谱(NIR)对可溶性固形物含量、干物质含量、果皮颜色和果实硬度4个质量指标进行无损测量,开发预测性NIR回归模型,并使用该模型测量‘雷尼尔’樱桃从果实开始着色到完全成熟阶段4个质量指标变化。结果表明,建立的可溶性固形物含量、干物质含量、果皮颜色和果实硬度模型的线性回归决定系数(R^(2))值分别为0.87、0.97、0.77、0.76。模型线性系数(R2)越接近1拟合效果越好,模型的拟合程度越高。R^(2)值均大于0.7,说明模型能够达到性能预期。可溶性固形物和干物质模型进行定量测定的准确性高于果皮颜色和果实硬度模型。樱桃果实成熟阶段,可溶性固形物与干物质逐渐增加,果皮颜色逐渐加深,硬度逐渐降低。本研究建立的模型可用于其他樱桃品种品质预测,同时可为进一步探索樱桃果实成熟阶段内部物质变化提供参考依据。

目的随着老龄化社会进程加速,老年人躯体衰弱和肌少症的患病率逐年上升,并带来诸多不良影响。膳食营养是防治躯体衰弱和肌少症的重要方式,但在社区环境中实施膳食营养干预受到诸多复杂因素影响。本综述旨在对相关研究中的促进和障碍因素进行系统综述,为制订相关健康管理方案提供参考。方法在Pub Med. .Web of Science 、Medline(Ovid). Embase(Ovid)和Cochrane Library 数据库进行检索,发表时间限定为建库至2023年1月。使用主题词和自由词组合完成检索。使用英国牛津大学循证医学中心质性研究质量评价工具(the Critical Appraisal Skills Program Qualiative Sudies Checklist)对纳入研究进行质量评价。利用社会生态建模框架对提取的信息进行编码和分析。本综述方案已在PROSPERO注册(CRD42022381339)。结果共纳入10项研究。其中,4项研究仅进行营养相关干预,而膳食营养和运动干预相结合的有6项。根据社会生态模型,从个体特征、外部环境和干预措施3个层面对促进和障碍因素进行了总结,包含10个副主题。结论对社区中的躯体衰弱和肌少症老年人实施膳食营养干预措施时,应整合个人内部动机和外部支持,为参与者制订“量身定制”的干预方案,并最大程度地优化可利用的人力和物理资源。
