Total saponins from Paris polyphylla against breast cancer
Basic assumptions, core connotations, and path methods of model modification—using confirmatory factor analysis as an example
Structural equation modeling (SEM) is a widely used statistical method in social science. However, many published articles employing SEM appear to contradict its underlying principles and assumptions, which undermines the scientific rigor of the research. Model modifications should be data-driven and clearly justified, rather than arbitrarily changing the relationships between variables. Removing measurement indicators can significantly reduce di…

Identification and Evolutionary Analysis of User Collusion Behavior in Blockchain Online Social Media
Blockchain technology has given rise to a series of new blockchain online social media (BOSMs), of which Steemit is representative. Such communities are based on a token reward system and attempt to engross users in the knowledge activities of the community through knowledge payment. Studies have found that the reward system of such communities has been abused (e.g., collusion for profit), but few studies have performed an in-depth analysis for t…
The effect of mindfulness on social media addiction among Chinese college students
Therefore, mindfulness-based interventions may be an effective way to alleviate social media addiction, especially mindfulness-based interventions targeting FOMO. At the end of the article, we also discussed the limitations of this study
Palynological evidence for the temporal stability of the plant community in the Yellow River Source Area over the last 7,400 years
Medicinal waterbirds in the traditional healthcare system
Background Eastern Khyber Pakhtunkhwa is home to a vast range of medicinal and edible waterbird species due to its diverse geographical environment. Waterbird species have been used for various ailments and cultural practices since ancient times, while ethno-pharmacological applications and cultural uses of waterbird species in this area have seldom been documented. This study is the first ethnomedicinal and cultural assessment of waterbird speci…
Vegetation biomass change in China in the 20th century
Vegetation biomass is a key and active component of the carbon cycle. Though China’s vegetation biomass in recent decades has been widely investigated, only two studies have quantitatively assessed its century-scale changes so far and reported totally opposite trends. This study provided the first multi-model estimates of China’s vegetation biomass change for the 20th century and its responses to historical changes in environmental and anthropoge…
Late-Holocene vegetation change reveals the environment of ancient people and the origin of Huashan cliff paintings in Guangxi, southwestern China
Human activities in the historical period were determined by the natural environment and social characteristics. The Zuojiang Huashan Rock Art Cultural Landscape in Guangxi is the most important World Heritage for prehistorical culture in southwestern China. However, knowledge about the natural environment and associated historic human–climate interactions during the period of cliff painting creation remains scarce, which has been an obstacle to …
Biome changes and their inferred climatic drivers in northern and eastern continental Asia at selected times since 40 cal ka bp
East Asian summer monsoon precipitation variations in China over the last 9500 years
To better understand the long-term changes of the East Asian summer monsoon precipitation ( P jja ), quantitative reconstructions and model simulations are needed. Here, we develop continental-scale pollen-based transfer functions for P jja with weighted averaging–partial least squares (WA-PLS) regression and a Bayesian multinomial regression method. We apply these transfer functions to a set of fossil pollen data from monsoonal China for quantit…
Spatial and temporal distributions of major tree taxa in eastern continental Asia during the last 22,000 years
This study investigates the spatial and temporal distributions of 14 key arboreal taxa and their driving forces during the last 22,000 calendar years before ad 1950 (kyr BP) using a taxonomically harmonized and temporally standardized fossil pollen dataset with a 500-year resolution from the eastern part of continental Asia. Logistic regression was used to estimate pollen abundance thresholds for vegetation occurrence (presence or dominance), bas…
Lipid-lowering and antioxidant activities of Jiang-Zhi-Ning in Traditional Chinese Medicine
We demonstrated for the first time lipid-lowering and antioxidant activities of extract and effective fractions as well as active constituents of JZN. Active constituents of JZN had the same biological effects with effective fraction and extract of JZN. Therefore, this study supports its ethnopharmacological use in Traditional Chinese Medicine to manage hyperlipidemia and paves a basis for establishing quality control method of Chinese medicine
Climate change in Inner Mongolia from 1955 to 2005—trends at regional, biome and local scales
This study investigated the climate change in Inner Mongolia based on 51 meteorological stations from 1955 to 2005. The climate data was analyzed at the regional, biome (i.e. forest, grassland and desert) and station scales, with the biome scale as our primary focus. The climate records showed trends of warmer and drier conditions in the region. The annual daily mean, maximum and minimum temperature increased whereas the diurnal temperature range…
Holocene land-cover changes on the Tibetan Plateau
Information on changes in land-surface features on the Tibetan Plateau (TP) during the Holocene may help our understanding of the forcing of monsoonal circulation. We analyse vegetation changes during the last 9000 years from pollen records of four lakes (Hurleg Lake in the Qaidam Basin; Qinghai Lake on the northeastern TP; Zigetang Lake on the central TP and Koucha Lake on the eastern TP) which represent different regions and vegetation types on…
A Simulation of Biomes on the Tibetan Plateau and Their Responses to Global Climate Change
The improved process-based equilibrium terrestrial biosphere model (BIOME3China) was run under the present climate to model the potential biomes on the Tibetan Plateau on a 109 grid. The simulated biome was basically in good agreement with a potential natural vegetation map based on a numerical comparison between two maps using the ΔV statistic (ΔV = 0.38). A coupled ocean-atmosphere general circulation model including sulfate aerosols was used t…
