Total astragalus saponins enhance the anti-liver fibrosis efficacy of Numb-overexpressed hUC-MSCs through stabilizing the Numb-p53 axis
Exploring Chlamydia trachomatis screening in Shenzhen
Objectives This study evaluates the feasibility of a sample pooling strategy for Chlamydia trachomatis detection in pre-marital and pre-pregnancy screening in China, where pooled testing for CT remains limited despite its use in COVID-19 and HIV screening. Methods From January to May 2024, 8,142 urine samples were collected from participants in pre-marital and pre-pregnancy health checks in Nanshan District. Positive urine samples with different …
Quality assessment of shrub observation data based on TLS
Vegetation restoration is one of the effective measures to deal with land degradation, and shrubs, as the pioneer plants, can improve soil conditions and accelerate the recovery of desertification. In recent decades, single‐scan (SS) and multiple‐scan (MS) modes have been widely used for forest inventories by terrestrial laser scanner (TLS) but TLS‐based shrub observation, and data quality uncertainties are less studied, especially in eco‐fragile…
Stability and micro‐topographic effects of Sophora moorcroftiana population on a restored alluvial fan, Southern Tibetan Plateau
The Tibetan Plateau, a vulnerable eco‐region undergoing global change, is hard to revegetate where land has become desertified due to the harsh habitat conditions. Sophora moorcroftiana shrubs, which are widely distributed in the middle reaches of the Yarlung Zangbo River basin of Tibet, China, have been naturally restored on desertified land during the last few decades. However, the influences of micro‐topography on the distribution and structur…
Feasibility of terrestrial laser scanning for quantification of vegetation structure parameters of restored sandy land in the southern Qinghai–Tibeten Plateau
The efficiency of ecosystem restoration of degraded land is typically assessed using vegetation structure parameters (VSP). However, the field measurement of VSP, particularly in the Qinghai–Tibet Plateau (QTP), which is a problematic area for ecological restoration because of its harsh environment, is generally time‐consuming and labour intensive. Therefore, new methods for VSP measurement should be developed. In this study, VSP were quantified …
Combining GPS and space syntax analysis to improve understanding of visitor temporal–spatial behaviour
Visitor tracking combined with space analysis has recently emerged as a method for understanding the relationship between visitor temporal–spatial behaviour and spatial features. In this study, 353 visitors were tracked using handheld GPS data loggers to enable calculation of visiting proportion, average time, and average speed in each space within the Lion Grove. Using ArcGIS to superimpose tracks and conduct a kernel density analysis, the popul…
The Misconception of Antibiotic Equal to an Anti-Inflammatory Drug Promoting Antibiotic Misuse among Chinese University Students
Massive misuse of antibiotics is one of the most important reasons for antimicrobial resistance (AMR). Misconceptions of antibiotics contribute to antibiotic misuse behaviors. This study aims to examine whether university students hold the misconception that Antibiotic is a Xiaoyanyao (literally means anti-inflammatory drug in Chinese), and association between this misconception and antibiotic misuse behaviors. A cross-sectional study was conduct…
Antibiotic misuse among university students in developed and less developed regions of China
BACKGROUND: Antimicrobial resistance (AMR) is a great threat to public health. The primary cause of AMR is human antibiotic misuse. Little is known about regional differences of antibiotic misuse behaviours in China. OBJECTIVES: To explore the antibiotic misuse behaviours among university students in western and eastern China and find out the regional differences. METHODS: test and logistic regression were adopted to assess the associations betwe…
