The brain-gut interaction theory is a multidimensional integrative concept based on the brain-gut axis， involving neural， endocrine， and immune regulatory networks as well as the gut microbiota. Zang-fu organs （脏腑） theory in traditional Chinese medicine （TCM） shows a high degree of consistency with the brain-gut interaction theory， and the core functions such as the spleen and stomach governing the ascending of the clear and descending of the turbid， the liver governing the free flow of qi， and the heart governing mental and emotional activities are closely associated with the multi-level regulatory mechanisms of the brain-gut axis. TCM therapy can modulate brain-gut interactions through multiple pathways in the treatment of spleen and stomach diseases， including the regulation of gastrointestinal hormone secretion， neurotransmitter levels， the hypothalamic-pituitary-adrenal （HPA） axis， immune homeostasis and inflammatory responses， as well as the gut microecology. However， current basic research on the brain-gut interaction theory in TCM for spleen and stomach diseases still faces several challenges， such as difficulties in integrating TCM spleen-stomach theory with modern pathophysiology， lack of innovation in research concepts， and limitations in research methodologies. It is therefore proposed that multidisciplinary collaboration， multi-omics technologies， and targeted research approaches should be adopted to provide more comprehensive methods for basic research on TCM spleen and stomach diseases， thereby promoting the in-depth development of brain-gut interaction theory.

The plant AT-rich sequence and zinc-binding protein (PLATZ) family is composed of plant-specific zinc finger-like transcription factors, which play important roles in plant growth, development, and stress tolerance. In this study, to gain a better understanding of the PLATZ gene in C. sinensis and elucidate its response under drought and high temperature conditions, the PLATZ gene family of the C. sinensis cultivar 'Tieguanyin' was systematically identified, and a total of 12 CsPLATZ family members were identified. Expasy online and other bioinformatics tools were used to analyze the members of the PLATZ gene family in terms of protein physicochemical properties, phylogenetic relationships, cis-acting elements, gene structures, and intra- and inter-species collinearity. The results of phylogenetic analysis classified the CsPLATZ family members into 2 subfamilies. The conserved domains and gene structures of PLATZ family members within the same subfamily had a high degree of consistency, whereas a certain degree of diversity was observed among the subfamilies. Twelve PLATZ genes were unevenly distributed across 7 chromosomes of C. sinensis and the promoter regions of these genes had multiple cis-acting elements related to hormone and stress responses. The collinearity analysis showed that there were 4 pairs of duplication events in the CsPLATZ gene family, all of which were segmental duplications. Based on this gene family, C. sinensis had a closer evolutionary relationship with A. thaliana than with O. sativa. The transcriptome analysis showed that the expression levels of CsPLATZ family members varied in different tissue samples of C. sinensis. 6 genes (CsPLATZ-1, CsPLATZ-2, CsPLATZ-3, CsPLATZ-4, CsPLATZ-6, and CsPLATZ-8) with high expression in shoots, young leaves, and roots were selected for high temperature and drought stress treatments, and their expression was quantified by qRT-PCR. The results indicated that the six genes might play important roles in the response to drought stress. In addition, CsPLATZ-2 and CsPLATZ-8 might have important functions in the response to high temperature stress. The results of this study will contribute to a better understanding of the biological functions of PLATZ genes and their possible roles in the growth, development, and stress responses of C. sinensis.

Objective:To investigate the characteristics of fatty acid metabolism in the hepatic steatosis (HS) population and to explore the role of inflammation in the relationship between fatty acid metabolism and HS.Methods:A total of 3 112 subjects from the 2011–2014 National Health and Nutrition Examination Survey (NHANES) database were included in this retrospective study, among whom 1 552 were in the HS group (weighted percentage: 49.87%) and 1 560 in the control group (weighted percentage: 50.13%). The differences in dietary fatty acid and serum free fatty acid (FFA) levels and metabolic characteristics were compared. Logistic and weighted quantile sum (WQS) regression models were used to evaluate the impacts of various FFA indexes on HS. Mediation analysis was conducted to examine whether inflammation served as a mediator in the relationship between FFA and HS.Results:Dietary fatty acid intake did not differ significantly between the HS and control groups. However, serum FFA metabolism characteristics differed between these two groups, with the concentrations of 28 FFAs in the HS group significantly higher than those in the control group. The risk of HS was correlated negatively with serum unsaturated fatty acids/saturated fatty acids ( OR=0.69, 95% CI: 0.64–0.75, P<0.001), polyunsaturated fatty acids/saturated fatty acids ( OR=0.63, 95% CI: 0.99–0.69, P<0.001), and Health Promotion Index ( OR=0.78, 95% CI: 0.74–0.82, P<0.001) but positively with thrombosis index ( OR=2.20, 95% CI: 1.89–2.55, P<0.001). The WQS model showed that behenic acid had the greatest contribution weight to increase the risk of HS among the 30 FFAs. After adjusting for confounding factors, the risk of HS increased by 167% (95% CI: 2.14–3.34, P<0.001) for each unit increase in the WQS index. Further mediation analysis showed that albumin/globulin ratio, white blood cell count, and neutrophil to platelet ratio significantly mediated the relationship between serum FFA and HS ( P<0.05). Conclusion:People with similar dietary fatty acid structures may present different serum FFA metabolism characteristics. Serum FFA level correlates with the risk of HS, and inflammation plays an important role in mediating the relationship between fatty acid metabolism and HS.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent inflammation and joint damage, accompanied by the accumulation of plasma cells, which contributes to its pathogenesis. Understanding the genetic alterations occurring during plasma cell differentiation in RA can deepen our comprehension of its pathogenesis and guide the development of targeted therapeutic interventions. Here, our study elucidates the intricate molecular mechanisms underlying plasma cell differentiation by demonstrating that PRDX1 interacts with DOK3 and modulates its degradation by the autophagy-lysosome pathway. This interaction results in the inhibition of plasma cell differentiation, thereby alleviating the progression of collagen-induced arthritis. Additionally, our investigation identifies Salvianolic acid B (SAB) as a potent small molecular glue-like compound that enhances the interaction between PRDX1 and DOK3, consequently impeding the progression of collagen-induced arthritis by inhibiting plasma cell differentiation. Collectively, these findings underscore the therapeutic potential of developing chemical stabilizers for the PRDX1-DOK3 complex in suppressing plasma cell differentiation for RA treatment and establish a theoretical basis for targeting PRDX1-protein interactions as specific therapeutic targets in various diseases.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

OBJECTIVE: To investigate the association between long-term glycemic control and cerebral infarction risk in patients with diabetes through a large-scale cohort study. METHODS: This prospective, community-based cohort study included 12,054 patients with diabetes. From 2006 to 2012, 38,272 fasting blood glucose (FBG) measurements were obtained from these participants. FBG trajectory patterns were generated using latent mixture modelling. Cox proportional hazards models were applied to assess the subsequent risk of cerebral infarction associated with different FBG trajectory patterns. RESULTS: At baseline, the mean age of the participants was 55.2 years. Four distinct FBG trajectories were identified based on FBG concentrations and their changes over the 6-year follow-up period. After a median follow-up of 6.9 years, 786 cerebral infarction events were recorded. Different trajectory patterns were associated with significantly varied outcome risks (Log-Rank P < 0.001). Compared with the low-stability group, Hazard Ratio ( HR) adjusted for potential confounders were 1.37 for the moderate-increasing group, 1.23 for the elevated-decreasing group, and 2.08 for the elevated-stable group. CONCLUSION Sustained high FBG levels were found to play a critical role in the development of ischemic stroke among patients with diabetes. Controlling FBG levels may reduce the risk of cerebral infarction.
