If you visit Dongsheng,a village in Dazhanchang,a town in Zhongning County,in Northwest China^s Ningxia Hui Autonomous Region,and if you ask the villagers about Ji Xiuhua,you are likely to hear the following:“Ji treats everyone equally,and she lends a helping hand to whomever is in trouble,”or“You can chat with Ji when you have problems to solve,and you will probably feel much better after chatting with her.”Ji’s story began more than 20 years ago……

神经退行性病变是认知功能退化和神经系统疾病的病理基础,受诸多机体内、外环境因素的影响。寄居于肠道中的微生物可影响机体健康和多种疾病的发生与发展,包括神经和精神疾病。肠道失调与阿尔茨海默病、帕金森病、亨廷顿病以及多发性硬化症等认知与运动功能障碍性疾病密切相关。研究发现,饮食干预可通过调节肠道微生物,改善肠-脑之间的联系,调控认知和情感等脑高级功能,缓解认知下降,抑制神经退行性病变,然而其内在机制尚不明确,可能与饮食干预调节肠道微生物群的构成及功能,进而改善肠道代谢、肠道内分泌等机制有关。本文通过分析饮食干预调节肠道微生物及相关的生理生化改变与脑认知和神经功能的关系,探讨饮食干预在肠道微生物与肠-脑联络与神经退行性疾病中的作用及机制。

宋代的家塾一般由中上层家庭或家族设置。根据各家塾的不同情况,家塾师长主要由三类人员构成:家族中有学问的父兄、亲朋中的知识渊博者以及专门聘请的家塾教师即馆客。家塾的学生以本家子弟为主,也有个别亲属家的孤幼。有见识的家长还会将一些优秀的族外孩童聚在家塾。家塾学生的入学年龄,从五岁到十岁以上不等。家塾一般常年开设,上课时间灵活,假日随各地风俗而定。宋代的家塾教育兼及蒙学和成人两个阶段,内容包括立规矩和学文化知识两部分。两宋家塾教育对基层士人的启蒙与成才,家学与时代文化的传承,及王朝统治人才的培养都有重要意义。然与举业的关联也导致了其功利性的弊端。

烟草叶面积指数(LAI)是评价其长势和预测产量的重要指标。利用高光谱遥感能够实现LAI的快速无损监测。为建立烟草LAI估算的最佳光谱指数及监测模型,通过设置不同种植密度处理,将田间观测和高光谱遥感技术结合,提取和分析了10个植被指数,并用二次多项式模型、对数模型、逐步回归模型(SMLR)和BP神经网络对烟草LAI进行估算。结果表明,NDVI、RVI、MCARI、GM1、GNDVI2和PSSRb等植被指数同烟草LAI均达到极显著正相关,相关系数均大于0.80。烟草LAI的二次多项式模型、对数模型、逐步回归模型(SMLR)和BP神经网络模型的决定系数R^2分别为0.69、0.57、0.89和0.90。经检验,4个模型的均方根误差RMSE分别为0.69、0.87、0.62和0.44。表明SMLR和BP神经网络LAI都取得了较为理想的结果,其中BP神经网络的精度最高、误差最小,更适合对烟草LAI进行反演。该结果为实现不同种植密度水平下烟草LAI的精确监测提供技术支持和地域参考。

Rapid assessment of foliar chlorophyll content in tobacco is critical for assessment of growth and precise management to improve quality and yield while minimizing adverse environmental impact. Our objective is to develop a precise agricultural practice predicting tobacco-leaf chlorophyll-a content. Reflectance experiments have been conducted on flue-cured tobacco over 3 consecutive years under different light quality. Leaf hyperspectral reflectance and chlorophyll-a content data have been collected at 15-day intervals from 30 days after transplant until harvesting. We identified the central band that is sensitive to tobacco-leaf chlorophyll-a content and the optimum wavelength combinations for establishing new spectral indices (simple ratio index, RVI;normalized difference vegetation index, NDVI;and simple difference vegetation index, DVI). We then established linear and BackPropagation (BP) neural network models to estimate chlorophyll-a content. The central bands for leaf chlorophyll-a content are concentrated in the visible range (410 - 680 nm) in combination with the shortwave infrared range (1900 - 2400 nm). The optimum spectral range for the spectral band combinations RVI, NDVI, and DVI are 440 and 470 nm, 440 and 470 nm, and 440 and 460 nm, respectively. The linear RVI, NDVI, and DVI models, SMLR model and the BP neural network model have respective R2
