ObjectiveTo explore the potential mechanism of Xiaoqinglongtang(XQL) in the prevention and treatment of high altitude pulmonary edema(HAPE) by network pharmacology, molecular docking, and molecular dynamics simulation, and to verify it by in vivo animal model. MethodsIn this study, the active ingredients, drug targets, and HAPE-related targets of XQL were collected from BATMAN-TCM, GeneCards, and Online Mendelian Inheritance in Man(OMIM) databases. The protein-protein interaction(PPI) network was constructed by using intersection targets, and the core targets were screened and visualized by Cytoscape software. Functional annotation and pathway analysis of the intersection targets were performed by gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) functional enrichment. AutoDock and GROMACS were used to evaluate the binding ability of active ingredients to key targets. In the experimental verification part, a mouse model of HAPE induced by hypobaric hypoxia(simulated 6 000 m altitude for 48 h) was established. The control effect was evaluated by hematoxylin-eosin(HE) staining, lung tissue water content, lung tissue wet/dry weight ratio, real-time quantitative polymerase chain reaction(Real-time PCR) detection of gene expression levels, and immunohistochemistry and Western blot detection of key protein expression. ResultsA total of 355 active ingredients of XQL, 2 142 targets, 716 HAPE-related targets, and 236 intersection targets were obtained by network pharmacology analysis. Key core targets such as interleukin (IL)-6, tumor necrosis factor (TNF), protein kinase B1 (Akt1), and hypoxia-inducible factor-1α (HIF-1α) were screened. The results of GO analysis of common targets involved 738 biological processes(BP), 72 cellular components(CC), and 135 molecular functions(MF). KEGG analysis effectively enriched two important signaling pathways: Phosphoinositol 3-kinase (PI3K)/Akt and HIF-1α. The results of molecular docking and molecular dynamics simulation showed that the screened active ingredients had good binding ability with key targets. In the HAPE model induced by hypobaric hypoxia(6 000 m, 48 h), the lung tissue water content, lung tissue wet/dry weight ratio, and pathological injury score of the model group were significantly increased(P<0.01), accompanied by exudation of a large number of red blood cells in the alveoli and alveolar interstitium, a significant increase in inflammatory cells, a significant widening of the alveolar septum, and mutual fusion between the alveoli. The XQL administration group significantly improved the above pathological changes(P<0.01). The results of inflammatory factor expression showed that compared with the control group, the model group showed significantly up-regulated expression of TNF-α, IL-6, and IL-1β in the lung tissue(P<0.01). Compared with the model group, the XQL administration group had significantly decreased expression of inflammatory factors(P<0.05, P<0.01). The mRNA expression of key pathway related genes PI3K, Akt1, mammalian target of rapamycin(mTOR), and HIF-1α was significantly increased in the model group(P<0.01), and decreased in a concentration-dependent manner after XQL administration(P<0.05, P<0.01). The expression levels of key proteins PI3K, phosphorylation(p)-PI3K, Akt1, p-Akt1, mTOR, p-mTOR, and HIF-1α in lung tissue were analyzed by immunohistochemistry and Western blot. Compared with the blank group, the model group showed increased expression of key proteins(P<0.05, P<0.01). Compared with the model group, the XQL administration group exhibited decreased expression of key proteins(P<0.05, P<0.01). ConclusionXQL can reduce lung inflammation and improve HAPE. The mechanism may be related to the regulation of PI3K/Akt/mTOR and HIF-1α pathways. This study provides a new idea and a theoretical basis for the treatment of HAPE with XQL.

Diabetes mellitus (DM) has become one of the most serious and common chronic diseases around the world, leading to various complications and a reduction in life expectancy. Increased sedentary behavior (SB) and decreased physical activity (PA) are important contributors to the rising prevalence of DM. This article reviews the research progress on the pathogenesis of DM, the effects of SB and PA on the risk of DM, aiming to explore the influence of different PA intensities, amounts, frequencies, durations and types on the incidence of DM. Research has shown that blood glucose levels tend to increase with the prolongation of SB. Within a certain range, PA intensity and amount are negatively correlated with the risk of DM; Performing PA for more than 3 days per week maintains normal glucose tolerance and lower blood pressure; Engaging in 150-300 min of moderate-intensity exercise or 75-150 min of high-intensity exercise per week reduces the risk of DM; PA during leisure time reduces the risk of DM, while PA during work increases the risk of DM; Both aerobic training and resistance training reduce the risk of DM, and the combination of the two training methods produces better benefits; Various types of exercises, such as cycling, soccer, aerobics, yoga and tai chi, all reduce the risk of DM. In summary, prolonged SB increases the risk of DM, while appropriate PA reduces the risk of DM. As the intensity, amount, and frequency of PA increase, the effect of reducing DM risk becomes more significant. Different exercise methods have different effects on reducing DM risk.

Recent studies have shown that an imbalance in iron metabolism can affect the composition and microstructural changes of bone, disrupting bone homeostasis and leading to osteoporosis(OP). The imbalance in iron metabolism, along with its induced local abnormal microenvironment and cellular iron death, has become a new focal point in OP research, drawing increasing attention from the academic community regarding the regulation of iron metabolism to prevent and manage OP. From the perspective of traditional Chinese medicine(TCM), iron metabolism imbalance has potential connections to TCM theories regarding internal organs, as well as treatments aimed at tonifying the kidney, strengthening the spleen, and activating blood circulation. Evidence is continually emerging that TCMs and effective components that tonify the kidney, strengthen the spleen, and activate blood circulation can prevent and manage OP by regulating iron metabolism. This article analyzes the relationship between iron and bone, as well as the effects of TCM formulations on improving iron metabolism and influencing bone metabolism, from the perspectives of iron metabolism mechanisms and TCM interventions, aiming to broaden existing clinical strategies for prevention and treatment and inject new momentum into the field of OP as it moves into a new era.

The chemical composition of Paeoniae Radix Alba(PRA) is complex, with primary secondary metabolites including monoterpenoids, tannins, triterpenoids, and flavonoids. In previous studies on the material basis of PRA, it was found that, in addition to the widely studied characteristic monoterpene glycosides, tannic acid components also play an important role in the efficacy of PRA. However, their pharmacological effects have not been thoroughly investigated. This paper reviews the tannic acid components in PRA, including pentagaloyl glucose(PGG), tetragaloyl glucose(TGG), trigaloyl glucose(TriGG), and gallic acid, along with their structures, properties, and characteristics to provide a detailed discussion of their pharmacological activities and related mechanisms, aiming to offer a theoretical basis for the material basis research and clinical application of PRA.

OBJECTIVE:
To investigate the relationship between physical activity and genetic risk and their combined effects on the risk of developing chronic obstructive pulmonary disease.
METHODS:
This prospective cohort study included 318,085 biobank participants from the UK. Physical activity was assessed using the short form of the International Physical Activity Questionnaire. The participants were stratified into low-, intermediate-, and high-genetic-risk groups based on their polygenic risk scores. Multivariate Cox regression models and multiplicative interaction analyses were used.
RESULTS:
During a median follow-up period of 13 years, 9,209 participants were diagnosed with chronic obstructive pulmonary disease. For low genetic risk, compared to low physical activity, the hazard ratios ( HRs) for moderate and high physical activity were 0.853 (95% confidence interval [ CI]: 0.748-0.972) and 0.831 (95% CI: 0.727-0.950), respectively. For intermediate genetic risk, the HRs were 0.829 (95% CI: 0.758-0.905) and 0.835 (95% CI: 0.764-0.914), respectively. For participants with high genetic risk, the HRs were 0.809 (95% CI: 0.746-0.877) and 0.818 (95% CI: 0.754-0.888), respectively. A significant interaction was observed between genetic risk and physical activity.
CONCLUSION
Moderate or high levels of physical activity were associated with a lower risk of developing chronic obstructive pulmonary disease across all genetic risk groups, highlighting the need to tailor activity interventions for genetically susceptible individuals.

Primary ciliary dyskinesia (PCD) is a clinically rare, genetically and phenotypically heterogeneous condition characterized by chronic respiratory tract infections, male infertility, tympanitis, and laterality abnormalities. PCD is typically resulted from variants in genes encoding assembly or structural proteins that are indispensable for the movement of motile cilia. Here, we identified a novel nonsense mutation, c.466G>T, in cilia- and flagella-associated protein 300 ( CFAP300 ) resulting in a stop codon (p.Glu156*) through whole-exome sequencing (WES). The proband had a PCD phenotype with laterality defects and immotile sperm flagella displaying a combined loss of the inner dynein arm (IDA) and outer dynein arm (ODA). Bioinformatic programs predicted that the mutation is deleterious. Successful pregnancy was achieved through intracytoplasmic sperm injection (ICSI). Our results expand the spectrum of CFAP300 variants in PCD and provide reproductive guidance for infertile couples suffering from PCD caused by them.
