乳酸菌对精神性疾病作用的研究进展

目前我国精神性疾病的发病率呈逐年上升趋势,如何缓解精神性疾病越来越受到人们关注。研究表明,乳酸菌可通过调节肠道免疫功能、促进产生神经信号物质、调节内分泌细胞激素等多种作用机制和途径帮助维持人脑及神经系统的正常功能。临床医学研究表明,乳酸菌具有对自闭症、抑郁症、精神分裂症、焦虑症等多种精神性疾病的预防及缓解作用,使用乳酸菌辅助药物治疗已成为目前精神性疾病治疗研究热点之一。本文总结了乳酸菌对精神性疾病的有益作用及其作用机制,旨在为乳酸菌在该领域的科研和应用提供借鉴和参考。      

二色补血草根中几种金属元素含量分析

采用微波消解-原子吸收光谱法对二色补血草根中K、Ca、Na、Mg、Zn、Fe、Cu和Mn八种金属元素含量进行了分析测定。结果表明,各元素平均回收率（n=7）在89%⁹6%之间能达到分析要求。八种金属元素在根中含量丰富,顺序为K>Na>Mg>Ca>Fe>Zn>Cu>Mn。对金属元素含量的测定有助于阐明二色补血草的药用机理。      

Drugs,Guts, Brains,but Not Rock and Roll: The Need to Consider the Role of Gut Microbiota in Contemporary Mental Health and Wellness of Emerging Adults

Emerging adulthood (ages 18–25) is a critical period for neurobiological development and the maturation of the hypothalamic–pituitary–adrenal axis. Recent findings also suggest that a natural perturbation of the gut microbiota (GM), combined with other factors, may create a unique vulnerability during this period of life. The GM of emerging adults is thought to be simpler, less diverse, and more unstable than either younger or older people. We postulate that this plasticity in the GM suggests a role in the rising mental health issues seen in westernized societies today via the gut–brain–microbiota axis. Studies have paid particular attention to the diversity of the microbiota, the specific function and abundance of bacteria, and the production of metabolites. In this narrative review, we focus specifically on diet, physical activity/exercise, substance use, and sleep in the context of the emerging adult. We propose that this is a crucial period for establishing a stable and more resilient microbiome for optimal health into adulthood. Recommendations will be made about future research into possible behavioral adjustments that may be beneficial to endorse during this critical period to reduce the probability of a “dysbiotic” GM and the emergence and severity of mental health concerns.

Cardiovascular and eye activity measures as indices for momentary changes in mental effort during simulated flight

This study examines effects of momentary changes in mental effort on cardiovascular and eye activity measures. A total of 19 male pilots performed an instrument flight task. Task load was manipulated by having the pilots perform flight manoeuvres of varying complexity. Multilevel analyses demonstrated clear effects of momentary changes in mental effort on both the cardiovascular and the eye activity measures. An increase in task load resulted in an increase of heart rate and a decrease in heart rate variability, mean dwell time and fixation duration. Heart rate differentiated between resting period and task execution. Heart rate variability from short data segments provided more insight in intermediate levels of mental effort. The eye activity measures were sensitive to intermediate levels of mental effort as well. Attitude changes resulted in an increase of mean dwell time and mean fixation duration. Task analysis is required to use eye measures as valid indices of mental effort. Having indications of the effects of changing mental demands during daily work of operators is of great importance nowadays. This paper presents an approach to estimate such effects on the basis of heart rate and eye activity measures. In particular, the use of averaged short-term heart rate variability measures is a relatively new aspect.
