Background With the rapid progression of aging in China, the challenge of multimorbidity has become a significant concern for both public health and clinical practice. Nocturnal sleep status, including sleep duration and quality, is crucial for regulating body metabolism and physiological functions in the elderly. However, current research on the relationship between nocturnal sleep status and multimorbidity was limited to specific regions or the middle-aged population. The association between nocturnal sleep status and prevalence of multimorbidity among community-dwelling older adults remains ambiguous. Objective To investigate the association between nocturnal sleep status and prevalence of multimorbidity among community-dwelling older adults. Methods In April 2023, a total of 11 917 community-dwelling older adults from the Chinese Longitudinal Healthy Longevity and Happy Family Study (CLHLS-HF, wave 2018) were selected as the participants. Multivariate Logistic regression was used to explore the association of sleep duration and sleep quality with the prevalence of multimorbidity, represented by odds ratios (OR) and 95% confidence intervals (95%CI). Additionally, restrictive cubic splines (RCS) based on Logistic regression analysis were utilized to analyze the dose-response relationship between sleep duration and prevalence of multimorbidity. Results Of the 11 917 community-dwelling older adults, with an average age of (84.4±11.4) years ranged from 65.0 to 117.0 years, 6 477 were females (54.35%) and 5 440 were males (45.65%). Multivariate Logistic regression results after adjusting for covariates such as gender, age, region, and years of education, indicated that compared to those with 6-8 h of nocturnal sleep duration, older adults with shorter sleep duration (

Food-medicines are a significant component for traditional Chinese medicine, Chinese cuisine culture, and the Healthy China initiative. Herein, we summarized the opportunities, development status, problems, and countermeasures for the food-medicine industry in China by using literature analysis, data mining, and expert consultation. Our research indicates that food-medicines have potential values in preventing and treating chronic diseases as well as delaying aging, and they are expected to become a daily material basis for disease prevention. Moreover, food-medicines are crucial for promoting the domestic and international economic cycles and supporting rural revitalization. Furthermore, we suggest that China should (1) increase its investment in research on foodmedicines to protect people’s health; (2) improve the regulation system to strengthen supervision and establish regulation and quality standards systems that accord with Chinese conditions; and (3) enhance international communication and trade to facilitate the implementation of the Belt and Road Initiative and the establishment of a global community of health for all.

Nitrogen fertilizer is the most frequently used fertilizer in the cultivation of medicinal plants, and has a significant contribution to their yields and quality. Yet, there is biased and excessive N application in medicinal crops. This study aims to quantitatively analyze the recommended N application concentrations for diverse medicinal species and disentangle the intricate relationships between soil fertility, N application rate (NAR), and the quality/yield of medicinal crops. We first characterized 179 medicinal species and 7 classes of phytometabolites therein, including terpenoids, flavonoids, phenylpropanoids, phenolics, alkaloids, etc., reported during the past three decades from the phylogenetic and spatial perspectives. The relationships between soil fertility, NAR, and medicinal crops were then subjected to statistical analyses. The pharmaco-phylogenetic and geographic distributions of NAR suggest that the impact of ecological/environmental factors on the N demand of medicinal plants was much greater than that of genetic endowments. We found that different medicinal species were distinct in N demand, which is related to soil fertility levels in different production areas. The NAR reported by China, 215.6 ± 18.6 kg/ha, was higher than that of other countries (152.2 ± 20.3 kg/ha; p = 0.023). Moderate N application generally increases the yield and phytometabolite content of medicinal crops, but excessive N application has the opposite effect. It is necessary to plan N concentration and formula fertilization on a case-by-case basis and with reference to empirical research. Our results provide baseline information and references for the rational application of N fertilizer in the precision agriculture of medicinal crops. [ABSTRACT FROM AUTHOR]

Sea buckthorn leaf tea, an emerging potential functional beverage product, has not yet had appropriate product standards and corresponding quality evaluation methods, and its poor taste directly affects the acceptance of the population, thus limiting its market consumption potential. In this study, two major packaging forms of sea buckthorn leaf tea available in the Chinese market were selected. The contents of total phenolics, total flavonoids, and 10 phenolic compounds, as well as the in vitro antioxidant capacity and sensory characteristics of sea buckthorn leaf tea were analyzed. Results showed that the quality of sea buckthorn leaf tea in the Chinese market varied widely. The total phenolic content, total flavonoid content, antioxidant activity, and consumer acceptance of bagged sea buckthorn leaf tea were higher than those of bulk sea buckthorn leaf tea. Multifactorial statistical analysis showed that the taste astringency of sea buckthorn leaf tea was closely related to ellagic acid and isorhamnetin‐3‐O‐neohesperidin. Furthermore, isorhamnetin‐3‐O‐neohesperidin had a greater effect on the antioxidant activity of sea buckthorn leaf tea. Therefore, ellagic acid and isorhamnetin‐3‐O‐neohesperidin can be used as potential quality markers for sea buckthorn leaf tea. This work provides a reference for taste improvement and quality control of sea buckthorn leaf tea. [ABSTRACT FROM AUTHOR]
