Objective To explore the role of neogambogic acid in the characteristics of colorectal cancer stem cells (CRC-CSCs) through the Wnt/β-catenin signaling pathway. Methods The colorectal cells SW480 and HCT166 were divided into control group and neogambogic acid groups (1.5, 3, 6, and 12 μmol/L). The viability of CRC-CSCs was determined by MTT method, and spheroid and clone formation assays were used to assess the capacity of spheroid formation and self-renewal ability of the cells. The effects of neogambogic acid on the apoptosis and cell cycle of CRC-CSCs were evaluated by flow cytometry assays. Real-time quantitative PCR was used to detect the mRNA expression levels of relative markers (CD133, CD44, ALDH1, Oct4, and Nanog) of CRC-CSCs, and the protein expression levels of the self-renewal marker (PCNA), apoptosis markers (cleaved caspase-3 and cleaved caspase-9), and Wnt/β-catenin signaling pathway markers (p-GSK3β, GSK3β, β-catenin, and Wnt) were analyzed using Western blot. Results Compared with the control group, after neogambogic acid treatment, the viability of SW480 and HCT116 cells decreased (P<0.05), the spheroid forming ability and the clone numbers of CRC-CSCs decreased (P<0.001, P<0.01) but the cell apoptosis rate increased (P<0.01), and cell cycle was arrested in G0/G1 phase. Moreover, neogambogic acid downregulated the mRNA and protein expression of relative markers of CRC-CSCs (CD133, CD44, ALDH1, Oct4, and Nanog), PCNA, p-GSK3β, β-catenin, and Wnt (P<0.05) and upregulated the expression of cleaved caspase-3, cleaved caspase-9, and GSK3β (P<0.01). Conclusion Neogambogic can inhibit the stem cell properties of colorectal cells via inhibition of Wnt/β-catenin signaling pathway. As a result, neogambogic acid may be an attractive agent against colorectal cancer.

Objective:
To investigate the impact of preschool children s aquatic motor skill (AMS) acquisition on their fundamental motor skill (FMS) development and the correlation between AMS and FMS development, so ao to provide a scientific basis for early childhood education and physical education teaching.
Methods:
From April to June 2024, 60 children, recruited by random sampling from a kindergarten in Taiyuan, were stratified randomly divided into an experimental group ( n =30) and a control group ( n =30). The experimental group were further divided into five classes of six each. They received AMS practice interventions twice weekly, 40 minutes per session, over eight weeks (16 sessions total) at a designated swimming center. The control group maintained their usual routine. Children s FMS and AMS were assessed pre and post intervention using the Test of Gross Motor Development-3rd (TGMD3) and Actual Aquatic Skills Test (AAST), respectively. Before and after test comparisons within and between groups employed t-tests, Wilcoxon signedrank tests, ANCOVA (including ranktransformed ANCOVA), and Cohen s d effect sizes were calculated for standardized mean differences. Spearman rank correlation was used to analyze relationships between FMS and AMS.
Results:
After the aquatic learning, the experimental group scored significantly higher than the control group on locomotor skills ( F=20.47, P <0.01, η 2=0.26), FMS ( F=4.59, P =0.04, η 2=0.08), and AMS ( F=109.71, P<0.01, η 2=0.79). The experimental groups improvement in locomotor skills 5.0(3.8, 7.3) versus the control group (2.8±2.5) yielded a medium effect size (Cohen s d =0.71); AMS gains in the experimental group [26.0(20.8, 28.0)] versus controls [1.0(0, 2.3)] showed a very large effect size (Cohen s d =4.73) (both P <0.01). Among preschool children, AMS acquisition was positively correlated with locomotor skills ( r =0.39) and overall FMS ( r =0.43)(both P <0.05). Skill specific assessments revealed lower proficiency in headfirst entry (immersion), treading water, and sagittalplane rotation.
Conclusion
Preschool children s acquisition of AMS has a positive effect on their FMS, with mutual facilitation between the two, especially in locomotor abilities.

Inflammation is involved in the development of various acute and chronic diseases in the body. Sustained inflammatory responses are key driving factors for diseases such as cancer, neurodegenerative diseases, cardiovascular diseases, metabolic syndrome, inflammatory bowel disease, and arthritis. Therefore, finding anti-inflammatory drugs is crucial for the prevention and treatment of various diseases. In recent years, there has been increasing attention to finding natural drugs with minimal toxic side effects. Lonicerae Japonicae Flos and Lonicerae Flos, as traditional Chinese medicines potent in clearing heat and removing toxins, have strong biological activity and multiple pharmacological effects. They are widely distributed in the plant world and have significant medicinal value. With the continuous advancement of the research on Lonicerae Japonicae Flos and Lonicerae Flos, they have been widely used in the medical field and possess great development potential. Currently, research mainly focuses on the anti-inflammatory mechanisms of Lonicerae Japonicae Flos and Lonicerae Flos, while systematic summaries of their anti-inflammatory active ingredients are rare. Therefore, this paper focuses on the differential analysis of the anti-inflammatory active components of Lonicerae Japonicae Flos and Lonicerae Flos. In addition, it reviewed the possible mechanisms by which extracts and active ingredients of Lonicerae Japonicae Flos and Lonicerae Flos may exert anti-inflammatory effects through various pathways, such as influencing the release of cellular inflammatory factors, regulating inflammatory signaling pathways such as nuclear factor-κB (NF-κB), mitogen-activated protein kinase (MAPK), signal transducer and activator of transcription 3 (STAT3), MAPK/extracellular signal-regulated kinase (ERK)/c-Jun N-terminal kinase (JNK), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/NF-κB, and Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling pathways, increasing antioxidant stress capacity, enhancing immune defense capabilities, and improving intestinal microbiota, aiming to provide a theoretical basis for the rational clinical application of Lonicerae Japonicae Flos and Lonicerae Flos.

Alzheimer′s disease (AD) is the most common type of cognitive impairment, characterized by complex pathology and pathogenesis. Regrettably, the effective therapeutic approaches remain unfulfilled, underscoring the pressing need to explore innovative preventive and therapeutic avenues. Research has illuminated the potential of intervening in risk factors and modifying lifestyle choices to diminish the incidence and decelerate the progression of AD. Notably, dietary patterns, such as Mediterranean diet, ketogenic diet, and calorie restriction have emerged as promising candidates for bolstering cognitive function in AD patients. These dietary approaches achieve this by multiple mechanisms, including mitigating the accumulation of neuropathological proteins, curbing neuroinflammation and oxidative stress, fortifying autophagy, and enhancing synaptic plasticity, etc. These findings strongly suggest that dietary intervention harbors the potential to serve as a novel and viable therapeutic strategy for AD. This review summarized the effects of different dietary patterns on the occurrence, progression, pathology and mechanism of AD.
