ObjectiveThis study aimed to investigate the action mechanism by which Banxia Xiexintang (BXT) inhibits epithelial-mesenchymal transition (EMT) in chronic atrophic gastritis (CAG) rats by regulating the interleukin-17(IL-17)/extracellular regulated protein kinases(ERK)/CCAAT enhancer binding protein β(C/EBPβ)signaling pathway, thereby providing new theoretical evidence for the treatment of CAG with classic traditional Chinese medicine formulas. MethodsA CAG rat model was established by using the combined factor method. After successful modeling, the rats were randomly divided into the model group, low-, medium-, and high-dose groups (0.549, 1.098, 2.196 g·kg-1, respectively) of BXT, and the positive drug group (vitacoenzyme, 0.3 g·kg-1). A normal control group was also set up. After 8 weeks of intervention, the pathological changes of gastric tissue were evaluated. The enzyme-linked immunosorbent assay (ELISA) was used to detect the contents of IL-17, tumor necrosis factor-α (TNF-α), cyclooxygenase-2 (COX-2), and C/EBPβ in serum, as well as the contents of EMT markers in gastric mucosal tissue including E-cadherin, N-cadherin, and vimentin. The immunohistochemistry method was employed to determine the localization and protein expression levels of IL-17, p-ERK, and C/EBPβ in gastric mucosal tissue. Western blot was used to detect the protein expressions of C/EBPβ, ERK, and its phosphorylated form (p)-ERK in gastric mucosa. Real-time polymerase chain reaction (Real-time PCR) was applied to measure the mRNA expression levels of ERK, COX-2, and C/EBPβ in gastric mucosa. ResultsCompared with those in the normal control group, the rats in the model group showed gastric mucosal glandular atrophy and inflammatory cell infiltration. The protein and their related mRNA expressions of C/EBPβ, ERK, and p-ERK in gastric mucosa were significantly increased (P<0.05,P<0.01). The levels of IL-17, TNF-α, COX-2, and C/EBPβ in serum were significantly increased (P<0.01). The contents of N-cadherin and vimentin in gastric mucosal tissue were significantly increased, while the content of E-cadherin was significantly decreased (P<0.01). Compared with the model group, after intervention with different doses of BXT, the pathological damage of the gastric mucosa was improved to varying degrees. The protein and mRNA expressions of C/EBPβ, ERK, and p-ERK in gastric mucosa were significantly reduced (P<0.05,P<0.01). The levels of IL-17, TNF-α, COX-2, and C/EBP β in serum were significantly decreased (P<0.01). The contents of N-cadherin and vimentin in gastric mucosa tissue were decreased, while the content of E-cadherin was increased (P<0.05,P<0.01). ConclusionBXT can effectively improve the pathological damage of gastric mucosal tissue in CAG rats. Its action mechanism may be related to reducing the levels of IL-17 and TNF-α in serum, regulating the IL-17/ERK/C/EBPβ signaling pathway and inhibiting the EMT process.

Esophageal cancer (EC) is a highly prevalent malignant tumor in China. The phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway, as one of the key oncogenic pathways, can promote the cell cycle progression, proliferation, migration, and invasion, induce chemoresistance, and inhibit apoptosis and autophagy of EC cells. Traditional Chinese medicine (TCM), with the advantages of targeting multiple points with multiple components to delay cancer progression, can target the PI3K/Akt signaling pathway for EC treatment. This article preliminarily discusses the molecular mechanism and role of the PI3K/Akt signaling pathway in EC and elaborates on the specific targets and efficacy of TCM in treating EC through intervention in the PI3K/Akt signaling pathway in the past five years. TCM materials and extracts inhibiting the PI3K/Akt signaling pathway in EC include Borneolum, spore powder of Ganoderma lucidum without spore coat, extract of Celastrus orbiculatus, root extract of Taraxacum, and Bruceae Fructus oil emulsion. TCM active ingredients exerting the effect include flavonoids, terpenoids, saponins, phenols, polysaccharides, alkaloids, and other compounds. TCM compound prescriptions with such effect include Qige San, Huqi San, Xuanfu Daizhetang, Tongyoutang and its decomposed prescriptions, Liujunzi Tang, and Xishenzhi Formula. In addition, TCM injections such as Compound Kushen Injection and Kang'ai injection also inhibit the PI3K/Akt signaling pathway in EC. This paper summarizes the role of the PI3K/Akt signaling pathway in EC and the TCM interventions, aiming to provide reference for the research and clinical application of new drugs for EC.

Objective:
To investigate the current status of emotional and behavioral problems among preschool children in Hefei, and to explore their association with the family rearing environment, providing scientific evidence for improving the family rearing environment and promoting children s mental health.
Methods:
From March to May 2023, a stratified cluster sampling method was applied to select 1 893 preschool children from five kindergartens in Hefei. Data on children s emotional and behavioral problems and family rearing environment were collected through electronic questionnaires. The Strengths and Difficulties Questionnaire (Parent Version) was employed to assess children s emotional and behavioral problems. Binary Logistic regression was conducted to analyze their association with family rearing environment.
Results:
Among preschool children, the prevalence rates of emotional symptoms, conducts, hyperactivity/inattention, peer relationship difficulties, and prosocial behavior were 9.7% (184 cases), 37.7% (713 cases), 16.7% (316 cases), 48.5% (918 cases), and 17.5% (332 cases), respectively. The abnormal detection rate of total difficulties score was 18.3% (346 cases). Binary Logistic regression analysis showed that higher maternal education level (postgraduate degree), parental daily interaction time ≥1 h, daily outdoor activity time for children ≥2 h, consistent family rearing attitudes, and nightly sleep duration for children ≥8 h were associated with lower abnormal risks of total difficulties score in preschool children [ OR(95%CI )=0.48(0.24-0.95), 0.66(0.49-0.90), 0.65(0.48-0.87), 0.39(0.29-0.52), 0.71(0.51-0.99),all P < 0.05 ].
Conclusion

With the completion of the "Human Genome Project" and the smooth progress of the "Herbal Genome Project", the research wave of RNAomics is gradually advancing, opening the research gateway for the modernization of traditional Chinese medicine (TCM) and initiating the post-genome era of medicinal plant RNA research. Therefore, this article proposes for the first time the concept of HerbRNomes, which involves constructing databases of medicinal plant, medicinal fungus, and medicinal animal RNA at different stages, from different origins, and in different organs. This research aims to explore the role of HerbRNA in self-genetic information transmission, functional regulation, as well as cross-species regulation functional mechanisms and key technologies. It also investigates application scenarios, providing a theoretical basis and research ideas for the resistance of TCM or medicinal plants to adversity and stress, molecular assistant breeding, and the development of small nucleic acid drugs. This article reviews recent research progress in elucidating the molecular mechanisms of the transmission and expression of genetic information, self-regulation and cross-species regulation of herbs at the RNA level, along with key technologies. It proposes a development strategy for small nucleic acid drugs based on HerbRNomes, providing theoretical support and guidance for the modernization of TCM based on HerbRNomes research.

Background:
The association of changes in metabolic syndrome (MetS) with cognitive function remains unclear. We explored this association using prospective and Mendelian randomization (MR) studies.
Methods:
MetS components including high-density lipoprotein cholesterol (HDL-C), systolic blood pressure (SBP), waist circumference (WC), fasting plasma glucose (FPG), and triglycerides were measured at baseline and two follow-ups, constructing a MetS index. Immediate, delayed memory recall, and cognitive function along with its dimensions were assessed by immediate 10- word recall test (IWRT) and delayed 10-word recall test (DWRT), and mini-mental state examination (MMSE), respectively, at baseline and follow-ups. Linear mixed-effect model was used. Additionally, the genome-wide association study (GWAS) of MetS was conducted and one-sample MR was performed to assess the causality between MetS and cognitive function.
Results:
Elevated MetS index was associated with decreasing annual change rates (decrease) in DWRT and MMSE scores, and with decreases in attention, calculation and recall dimensions. HDL-C was positively associated with an increase in DWRT scores, while SBP and FPG were negatively associated. HDL-C showed a positive association, whereas WC was negatively associated with increases in MMSE scores, including attention, calculation and recall dimensions. Interaction analysis indicated that the association of MetS index on cognitive decline was predominantly observed in low family income group. The GWAS of MetS identified some genetic variants. MR results showed a non-significant causality between MetS and decrease in DWRT, IWRT, nor MMSE scores.
Conclusion
Our study indicated a significant association of MetS and its components with declines in memory and cognitive function, especially in delayed memory recall.

BACKGROUND:
Spicy food consumption has been reported to be inversely associated with mortality from multiple diseases. However, the effect of spicy food intake on the incidence of vascular diseases in the Chinese population remains unclear. This study was conducted to explore this association.
METHODS:
This study was performed using the large-scale China Kadoorie Biobank (CKB) prospective cohort of 486,335 participants. The primary outcomes were vascular disease, ischemic heart disease (IHD), major coronary events (MCEs), cerebrovascular disease, stroke, and non-stroke cerebrovascular disease. A Cox proportional hazards regression model was used to assess the association between spicy food consumption and incident vascular diseases. Subgroup analysis was also performed to evaluate the heterogeneity of the association between spicy food consumption and the risk of vascular disease stratified by several basic characteristics. In addition, the joint effects of spicy food consumption and the healthy lifestyle score on the risk of vascular disease were also evaluated, and sensitivity analyses were performed to assess the reliability of the association results.
RESULTS:
During a median follow-up time of 12.1 years, a total of 136,125 patients with vascular disease, 46,689 patients with IHD, 10,097 patients with MCEs, 80,114 patients with cerebrovascular disease, 56,726 patients with stroke, and 40,098 patients with non-stroke cerebrovascular disease were identified. Participants who consumed spicy food 1-2 days/week (hazard ratio [HR] = 0.95, 95% confidence interval [95% CI] = [0.93, 0.97], P <0.001), 3-5 days/week (HR = 0.96, 95% CI = [0.94, 0.99], P = 0.003), and 6-7 days/week (HR = 0.97, 95% CI = [0.95, 0.99], P = 0.002) had a significantly lower risk of vascular disease than those who consumed spicy food less than once a week ( Ptrend <0.001), especially in those who were younger and living in rural areas. Notably, the disease-based subgroup analysis indicated that the inverse associations remained in IHD ( Ptrend = 0.011) and MCEs ( Ptrend = 0.002) risk. Intriguingly, there was an interaction effect between spicy food consumption and the healthy lifestyle score on the risk of IHD ( Pinteraction = 0.037).
CONCLUSIONS
Our findings support an inverse association between spicy food consumption and vascular disease in the Chinese population, which may provide additional dietary guidance for the prevention of vascular diseases.

Research on IgG4-related disease (IgG4-RD), an autoimmune condition recognized to be a unique disease entity only two decades ago, has processed from describing patients' symptoms and signs to summarizing its critical pathological features, and further to investigating key pathogenic mechanisms. Challenges in gaining a better understanding of the disease, however, stem from its relative rarity-potentially attributed to underrecognition-and the absence of ideal experimental animal models. Recently, with the development of various high-throughput techniques, "omics" studies at different levels (particularly the single-cell omics) have shown promise in providing detailed molecular features of IgG4-RD. While, the application of omics approaches in IgG4-RD is still at an early stage. In this paper, we review the current progress of omics research in IgG4-RD and discuss the value of machine learning methods in analyzing the data with high dimensionality.
