Children with autism exhibit more pronounced symptoms of both problem behaviors and motor coordination difficulties. Yoga, recognized as an effective intervention modality, can be valuable after assessing its efficacy in addressing problem behaviors and motor coordination challenges, ultimately contributing to symptom alleviation in autism. The randomized controlled trial (RCT) was used to divide 17 children with autism into an intervention group (n = 9) and a control group (n = 8). The intervention group participated in an 8-week yoga intervention training (three sessions/week, 45–50 min/session), and the control group did not participate in yoga training but only in daily program activities. Pre-test, mid-test, post-test, and after delayed test, teachers assessed the effect of yoga intervention on problem behaviors of children with autism through the Aberrant Behavior Checklist (ABC) and the effect of yoga intervention on motor coordination through the Movement Assessment Battery for Children—Second Edition (MABC2). Results show that the yoga intervention is effective in reducing problem behaviors and improving motor coordination in children with autism. Yoga intervention significantly reduces irritability and social withdrawal in children with autism. Yoga intervention had the most significant improvement in ball skills and static and dynamic balance.

Maternal immune activation (MIA) during pregnancy has been increasingly recognized as a critical factor in the development of neurodevelopmental disorders, with potential sex-specific impacts that are not yet fully understood. In this study, we utilized a murine model to explore the behavioral and molecular consequences of MIA induced by lipopolysaccharide (LPS) administration on embryonic day 12.5. Our findings indicate that male offspring exposed to LPS exhibited significant increases in anxiety-like and depression-like behaviors, while female offspring did not show comparable changes. Molecular analyses revealed alterations in pro-inflammatory cytokine levels and synaptic gene expression in male offspring, suggesting that these molecular disruptions may underlie the observed behavioral differences. These results emphasize the importance of considering sex as a biological variable in studies of neurodevelopmental disorders and highlight the need for further molecular investigations to understand the mechanisms driving these sex-specific outcomes. Our study contributes to the growing evidence that prenatal immune challenges play a pivotal role in the etiology of neurodevelopmental disorders and underscores the potential for sex-specific preventative approaches of MIA.

Based on meteorological data in the past 53 years (1966-2018), this paper analyzes the climate comfort changes in Qinhuangdao by using the method of climate comfort evaluation and trend analysis. The results show that the climate comfort changes in the northern mountainous area of Qinhuangdao, the central plain and the southeastern coastal areas are consistent, and there are spatial differences. In general, Qinhuangdao's climate comfort is mainly comfortable to cool, the comfort and relative comfort levels of each region account for 47% to 49%, and the cold discomfort level accounts for 34% to 37%,the hot and hotter discomfort levels are rare. In the past 53 years, the climate comfort in summer and winter shows a warming trend, and the warming range in winter was larger than that in summer. In the past 53 years, the number of hot uncomfortable days has increased sharply since the 1990s, and the number of cold uncomfortable days has decreased year by year. The number of hot uncomfortable days increases with the decrease of altitude and latitude of the station in space, while the number of cold uncomfortable days is the opposite. The climate is comfortable or relatively comfortable from May to October. The whole area of Qinhuangdao is suitable for tourism and recuperation from May to October. There is no intense hot in July and August. The “slightly hot” weather provides favorable weather conditions for people to swim in the sea, the relative cold climate in March, April and November is a good time for outdoor mountain climbing, the climate is cold and uncomfortable from December to February, not suitable for mass tourism, but suitable for ice and snow tourism activities. Therefore, it can be considered that Qinhuangdao is suitable for tourism all seasons. This provides a basis for tourism development and planning in Qinhuangdao and for studying the impact of climate change on tourism, and provides life and travel weather service guidance for the Kangyang group that came to "Qinhuangshanhai, Kangyangfudi".

Myeloid-derived suppressor cells (MDSCs) are heterogeneous cell populations that promote tumor development by inhibiting innate and adaptive immunity. Under physiological conditions, neutrophils have a short survival time in vivo. However, G-MDSCs accumulate abnormally in most tumor hosts, and the mechanisms underlying G-MDSC persistence remain to be clarified. This study utilized flow cytometric analysis and in vivo assays to elucidate these mechanisms. It was observed that the apoptosis of G-MDSCs in the peripheral blood of mice was reduced under tumor conditions, whereas an increase in granulocyte colony-stimulating factor (G-CSF) promoted the survival of G-MDSCs. Furthermore, G-CSF reduced the apoptosis of G-MDSCs by activating the Erk/CREB pathway. Thus, inhibition of G-CSF/Erk/CREB signaling may promote the apoptosis of G-MDSCs and shorten their persistence under tumor conditions, as well as attenuate tumor progression.
