肌少症在老年慢性阻塞性肺疾病人群中患病率较高,与慢性阻塞性肺疾病密切相关。两者共存不仅损害患者身心健康,还增加了临床治疗的难度。现代医学对慢性阻塞性肺疾病合并肌少症的发病机制研究较少,临床治疗也以对症处理为主,以缓解症状、减少COPD急性发作次数为目的。对于老年慢性阻塞性肺疾病和肌少症临床共病之间可能存在内在联系,但目前对该合并症关注不足。随着生物技术的不断进步,肠道菌群的作用在许多慢性疾病的发病机制中越来越受到重视。有研究表明,老年慢性阻塞性肺疾病患者肠道菌群存在明显失衡,而肌少症的发生也与肠道菌群关系较为密切。本文通过探讨肠道菌群与老年慢性阻塞性肺疾病合并肌少症之间的相互关系,分析肠道菌群的失衡可能是导致老年慢性阻塞性肺疾病合并肌少症的关键因素之一,提出以微生态疗法调节肠道菌群失衡,可能成为临床防治老年慢性阻塞性肺疾病合并肌少症的一种新途径。

Common evaluation methodology of sodium(Na)-containing two-electrode or three-electrode configurations overlooks the interference from highly reactive Na metal,leading to the underestimation or inconsistent performance of low-potential hard carbon(HC)***,the trap of Na metal was systematically investigated with or without applied current,uncovering its inadequacy as the reference or counter electrode in different configurations.A Na-metal-free three-electrode protocol is proposed for evaluating the actual Na^(+)-storage capability of the typical low-potential HC *** avoiding Na crosstalk and precisely controlling the working electrode's potential,the actual electrochemical performance of HC in the carbonate esterbased electrolyte can be recognized with high capacity of 222 mAh g^(-1)at 2 C and 113 mAh g^(-1)at 5 C,correcting the misunderstanding of the inferior performance of HC in coin-type half cells(68%and 50%undervaluation at 2 C and 5 C,respectively).The advanced protocol is expected to reduce misunderstandings or underestimation due to evaluation methods and to guide the development of high-performance battery materials.

Aerosol optical depth(AOD) is the most basic parameter that describes the optical properties of atmospheric aerosols,and it can be used to indicate aerosol content. In this study, we assimilated AOD data from the Fengyun-3 A(FY-3 A) and MODIS meteorological satellite using the Gridpoint Statistical Interpolation three-dimensional variational data assimilation system. Experiments were conducted for a dust storm over East Asia in April 2011. Each 0600 UTC analysis initialized a24-h Weather Research and Forecasting with Chemistry model forecast. The results generally showed that the assimilation of satellite AOD observational data can significantly improve model aerosol mass prediction skills. The AOD distribution of the analysis field was closer to the observations of the satellite after assimilation of satellite AOD data. In addition, the analysis resulting from the experiment assimilating both FY-3 A/MERSI(Medium-resolution Spectral Imager) AOD data and MODIS AOD data had closer agreement with the ground-based values than the individual assimilation of the two datasets for the dust storm over East Asia. These results suggest that the Chinese FY-3 A satellite aerosol products can be effectively applied to numerical models and dust weather analysis.
