ObjectiveTo investigate the therapeutic effect of paeoniflorin on metabolic dysfunction-associated fatty liver disease (MASLD) combined with insulin resistance (IR), and to elucidate its regulatory mechanisms on the Toll-like receptor 4 (TLR4)/nuclear transcription factor (NF)-κB-insulin receptor substrate 1 (IRS1) inflammation-insulin signaling axis. MethodsMASLD mouse model was established using a 60% high-fat diet. Mice were randomly assigned to a normal control group, a MASLD model group, and paeoniflorin groups (low dose: 25 mg·kg-1·d-1, medium dose: 50 mg·kg-1·d-1, high dose: 100 mg·kg-1·d-1), receiving intragastric administration for consecutive 12 weeks. Concurrently, a palmitic acid/oleic acid (PA/OA)-induced lipid deposition model was established in HepG2 cells. Cell counting kit-8 (CCK-8) assay was performed to determine the optimal concentrations of PA/OA and paeoniflorin for intervention. Mice body weight, liver index, and serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglycerides (TG), and total cholesterol (TC) were measured. Fasting blood glucose (FBG) and fasting insulin (FINS) levels were measured, and the homeostatic model assessment of insulin resistance (HOMA-IR) was calculated, while an oral glucose tolerance test (OGTT) was performed to evaluate glucose metabolism. Hematoxylin and eosin (HE) staining was used to observe pathological changes and inflammatory cell infiltration in liver tissue, and oil red O staining was used to evaluate lipid droplet deposition in liver tissue and HepG2 cells. Potential targets were screened using network pharmacology and molecular docking. Western blot analysis was performed to detect the expression of HSP90AA1, TLR4, p-NF-κB p65, p-IRS1, and p-Akt proteins in liver tissue and HepG2 cells. ResultsCompared with the normal control group, mice in the MASLD model group exhibited significantly increased body weight, liver index, and serum levels of ALT, AST, TG, and TC, as well as markedly elevated FBG, FINS, and HOMA-IR, and impaired glucose tolerance (P<0.01). HE staining revealed marked hepatic steatosis and inflammatory cell infiltration, while oil red O staining showed a significant increase in lipid droplet deposition. Compared with the MASLD model group, after intervention with various doses of paeoniflorin, the increase in body weight and liver index was reduced, serum ALT, AST, TG, and TC levels decreased, and FBG, FINS, and HOMA-IR were significantly lowered, with glucose tolerance markedly improved (P<0.05, P<0.01), showing a certain dose-dependent trend. HE and oil red O staining results showed a marked reduction in hepatic steatosis and lipid deposition. In vitro experiments demonstrated that, compared with the control group, PA/OA treatment significantly induced increased lipid deposition in HepG2 cells. Compared with the model group, paeoniflorin intervention significantly reduced intracellular lipid droplets, and lipid deposition showed a dose-dependent decreasing trend. Mechanism studies indicated that, compared with the normal control group, the MASLD model group exhibited significantly elevated expression of TLR4, HSP90AA1, and p-NF-κB p65, while p-IRS1 (Ser307) expression was elevated and p-Akt (Ser473) expression was reduced (P<0.01). Compared with the model group, the expression of the aforementioned proteins was significantly reversed in all treatment groups following intervention (P<0.05, P<0.01). ConclusionPaeoniflorin significantly alleviates lipid deposition and insulin resistance in MASLD mice. Its mechanism of action may involve targeting HSP90AA1, TLR4, and NF-κB1 to regulate the TLR4/NF-κB-IRS1 inflammation-insulin signaling axis. This regulation suppresses inflammatory responses and restores insulin signaling, thereby ameliorating abnormalities in glucose and lipid metabolism.

ObjectiveTo investigate the expression of prefrontal cortical neurons, methyltransferase-like 3 (METTL3), fat mass and obesity-associated gene (FTO), and AlkB homolog 5 (ALKBH5) proteins in a mouse model of post-traumatic stress disorder (PTSD). MethodsA PTSD mouse model was established using a single prolonged stress and foot shock stimulation (SPSS) method. The despair, anxiety, and learning and memory functions of PTSD mice were assessed through the open field test, Y-maze test, and forced swimming test. Neuronal damage was detected via HE and Nissl staining. The expression levels of METTL3, FTO, ALKBH5, and neuronal nuclear protein (NEUN) were assessed by Western blot and immunofluorescence staining. ResultsCompared to control group, PTSD mice subjected to SPSS exhibited signs of despair, anxiety, and impaired learning and memory. HE and Nissl staining results showed neuronal damage in the prefrontal cortex of PTSD mice. Western blot and immunofluorescence staining results showed that the expression of the m6A-related proteins METTL3 and FTO decreased, while the expression of ALKBH5 increased in the prefrontal cortex. Additionally, NEUN protein levels showed a declining trend. ConclusionThe pathogenesis of PTSD may be associated with neuronal damage in the prefrontal cortex and alterations in m6A methylation proteins.

ObjectiveTo investigate the effect of protein arginine methyltransferase 5 (PRMT5) on the angiogenesis of colorectal cancer (CRC) through the Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling pathway. MethodsThe expression and prognostic value of PRMT5 in CRC tissues were analyzed based on the cancer genome atlas (TCGA) and gene expression omnibus (GEO) databases. A total of 105 pairs of cancer tissues and matched adjacent non-tumor tissues were collected from CRC patients, and PRMT5 expression was detected by immunohistochemistry (IHC); Western blot was used to detect the PRMT5 protein level in normal colonic epithelial cells (FHC) and CRC cell lines (including RKO, SW480). SW48 and LoVo cells were divided into negative control (NC) group and PRMT5 knockdown interference group. After the stable knockdown cell models were successfully constructed, the effects of conditioned medium on the proliferation, cell cycle, migration and tube formation abilities of human umbilical vein endothelial cells (HUVECs) were detected; the correlation between PRMT5 and vascular endothelial growth factor A (VEGFA) was analyzed by real-time quantitative polymerase chain reaction (RT-qPCR) and enzyme-linked immunosorbent assay (ELISA). Gene set enrichment analysis (GSEA) and cytoplasm-nucleus separation assay were performed to verify the regulatory pathway. ResultsPRMT5 was highly expressed in CRC tissues and cell lines, which was significantly correlated with poor prognosis and pathological characteristics of patients (all P<0.05); PRMT5 knockdown could significantly inhibit the angiogenesis-related abilities of HUVECs (all P<0.05) and down-regulate the expression of VEGFA (all P<0.01). GSEA results indicated that PRMT5 expression was significantly associated with the activation of JAK2/STAT3 signaling pathway (all P<0.001). PRMT5 knockdown could inhibit the activation of JAK2/STAT3, the nuclear translocation of STAT3 and the protein level of phosphorylated STAT3 (p-STAT3) in the nucleus, thus inhibiting the expression of VEGFA. ConclusionPRMT5 is highly expressed in CRC tissues and indicates poor prognosis of patients. It promotes the nuclear translocation and transcriptional activity of STAT3 by activating the JAK2/STAT3 pathway and drives the expression of VEGFA to promote tumor angiogenesis.

These pathogens included influenza A virus(FluA), influenza B virus(FluB), parainfluenza virus(PIV), respiratory syncytial virus (RSV), adenovirus (ADV), human rhinovirus (HRV), human bocavirus (HBoV), human coronavirus (HCoV), human metapneumovirus(HMPV), Mycoplasma pneumoniae(MP), and Chlamydia (Ch). Count data were described as [ n(%)], and the chi-square test/Fisher′s exact test was used to compare the differences in rates between groups. Epidemiological features, including positive detection rates, pathogen profiles, and correlations with region, sex, age and month, were analyzed. Results:Among 22 769 children with ARTI, pathogens were detected in 16 213 cases (71.21%), including 13 340 single infections (58.59%).The detection rates of single pathogens in descending order were human rhinovirus (HRV, 12.95%), Mycoplasma pneumoniae(MP, 12.27%), respiratory syncytial virus(RSV, 11.12%), influenza A virus (Flu-A, 7.98%), parainfluenza virus(PIV, 4.66%), human metapneumovirus(HMPV, 4.60%), adenovirus(ADV, 2.70%), human bocavirus(HBoV, 0.84%), human coronavirus(HCoV, 0.82%), influenza B virus(Flu-B, 0.47%) and Chlamydia(Ch, 0.18%).Mixed infections occurred in 2 873 cases(12.62%), primarily dual infections(2 679 cases).Regional analysis revealed significant disparities:Luoyuan County Hospital (Fuzhou) exhibited the highest total detection rate(86.59%, 1 414/1 633)and mixed infection rate(23.27%, 380/1 633)(both P<0.001), with notably elevated MP (26.39%, 431/1 633);Jian′ou City Hospital(Nanping) ranked second for Flu-A(14.21%, 409/2 879), RSV(13.20%, 380/2 879) and mixed infections(17.12%, 493/2 879);Lianjiang County Hospital(Fuzhou) showed distinct prevalence of Flu-A(10.68%, 130/1 217), PIV(6.00%, 73/1 217), and HBoV(1.73%, 21/1 217); Yong′an City Hospital (Sanming) reported high MP (26.07%, 238/913) and RSV(12.38%, 113/913);Shaowu City Hospital(Nanping) was dominated by MP (18.60%, 407/2 188) and HRV(13.39%, 293/2 188); Tingzhou Hospital(Longyan) had the highest HRV (17.88%, 407/2 276) and Flu-B (0.75%, 17/2 276); and Fuzhou Children′s Hospital showed elevated ADV(3.38%, 394/11 663) and HCoV(1.08%, 126/11 663). Except for Flu-B(0.47%, 108/22 769; P=0.054) and Ch(0.18%, 40/22769; P=0.900), all pathogens and mixed infections exhibited significant regional variations ( P<0.05).Gender analysis indicated higher detection rates of HRV, RSV, Flu-A, ADV, PIV, HBoV and mixed infections in males, while MP, HMPV, Flu-B, HCoV, and Ch were more prevalent in females, with statistically significant differences for HRV and MP (both P<0.001). Age stratification showed the highest overall detection rate in the 3-<6 years group (75.48%; P<0.001): RSV and Ch peaked in infants (<1 year), HRV, PIV, ADV and HBoV in toddlers (1-<3 years), HMPV, HCoV, and mixed infections in preschool children (3-<6 years), and MP, Flu-A and Flu-B in older children (6-<18 years).Analyzing the prevalent months, the monthly prevalence trends of pathogens in various regions are similar.Seasonal trends demonstrated year-round HRV activity (peaking in spring/autumn), MP prevalence in autumn/winter, RSV surges in spring-summer (April-June) and late summer-autumn (August-October), and Flu-A predominanced in winter-spring. Conclusion:Multiplex PCR with fragment analysis demonstrated high diagnostic efficacy. The top 4 non-bacterial pathogens in Fujian Province′s ARTI-hospitalized children in 2023 were HRV, MP, RSV and Flu-A. Pathogen distribution exhibited significant regional, age and seasonal variations, emphasizing the need for targeted prevention strategies.

Objective:To investigate the neurorestorative effect of basic fibroblast growth factor (bFGF) on neurological function recovery in rats with spinal cord injury and its potential mechanisms.Methods:Ninety adult SD rats were selected and randomly divided into 6 groups using a random number table: sham-operated group ( n=24), spinal cord injury group ( n=24), bFGF group ( n=24), bFGF autophagy pathway validation group ( n=6), bFGF+rapamycin group ( n=6), and bFGF+MHY1485 group ( n=6). A spinal cord injury model was established by impacting the T 10 spinal cord segment using a self-made Allen′s weight-drop impactor. The sham-operated group underwent a 3 cm midline dorsal incision without spinal cord injury; the bFGF group received immediate intrathecal injection of 100 μl bFGF solution (20 μg/L) after injury; the sham surgery group and spinal cord injury group received an equal volume of saline after injury; the bFGF autophagy pathway validation group received the identical treatment as the bFGF group; the bFGF+rapamycin group received the same treatment as the bFGF group with additional intraperitoneal injection of rapamycin (4 mg·kg -1·d -1); the bFGF+MHY1485 group received the identical bFGF treatment plus intraperitoneal injection of MHY1485 (10 mg·kg -1·d -1). At 28 days after injury, the rats were sacrificed and the spinal cord tissue was collected at 5 mm from the injury epicenter for HE staining and pathological observation. At 7, 14, 21, and 28 days after injury, BBB scoring was used to assess hindlimb motor function; P wave latency and P1-N1 wave amplitude were recorded to evaluate neuroelectrophysiological changes; Western blot analysis was performed to detect the expression levels of phosphorylated mammalian target of rapamycin (p-mTOR)/mammalian target of rapamycin (mTOR) and microtubule-associated protein light chain 3-II (LC3-II) and evaluate changes in mTOR signaling pathway and autophagy activity. At 28 days after injury, behavioral alterations, neuroelectrophysiological changes, and auctophagy-related protein expression levels were assessed in the bFGF autophagy pathyway validation group, bFGF+rapamycin group and bFGF+MHY1485 group. Results:At 28 days after injury, the sham-operated group exhibited regular nuclear morphology, while the spinal cord injury group showed disordered cell structures and the bFGF group displayed relatively normal nuclear morphology. At 7, 14, 21, and 28 days after injury, the BBB scores in both the spinal cord injury group and bFGF group were lower than those in the sham-operated group ( P<0.01), with higher scores in the bFGF group than those in the spinal cord injury group ( P<0.01). At 7, 14, 21, and 28 days after injury, P-wave latency was longer and P1-N1 wave amplitude was lower in both the spinal cord injury group and bFGF group compared to those in the sham-operated group ( P<0.01), with shorter P-wave latency and higher P1-N1 wave amplitude in the bFGF group compared to those in the spinal cord injury group ( P<0.01). Western blot results indicated that at 7, 14, 21, and 28 days after injury, in the spinal cord injury group, p-mTOR/mTOR levels were lower than those in both the sham-operated group and bFGF group ( P<0.01), while LC3-II expression levels were higher ( P<0.01); in the bFGF group, p-mTOR/mTOR levels were higher than those in the spinal cord injury group but lower than those in the sham-operated group ( P<0.01), and LC3-II expression levels were lower than those in the spinal cord injury group but higher than those in the sham-operated group ( P<0.01). At 28 days after injury, the BBB scores were higher in both the bFGF autophagy pathway validation group and bFGF+MHY1485 group than those in the bFGF+rapamycin group ( P<0.01), with higher scores in the bFGF+MHY1485 group than those in the bFGF autophagy pathway validation group ( P<0.01). P-wave latency was shorter in both the bFGF autophagy pathway validation group and bFGF+MHY1485 group than those in the bFGF+rapamycin group ( P<0.01), with shorter P-wave latency in the bFGF+MHY1485 group than that in the bFGF autophagy pathway validation group ( P<0.01). P1-N1 wave amplitude was lower in both the bFGF autophagy pathway validation group and bFGF+MHY1485 group than that in the bFGF+rapamycin group ( P<0.01), with lower P1-N1 wave amplitude in the bFGF+MHY1485 group than that in the bFGF autophagy pathway validation group ( P<0.01). The p-mTOR/mTOR levels were higher in both the bFGF autophagy pathway validation group and bFGF+MHY1485 group than those in the bFGF+rapamycin group ( P<0.01), with higher p-mTOR/mTOR levels in the bFGF+MHY1485 group than those in the bFGF autophagy pathway validation group ( P<0.01). The LC3-II expression levels were higher in both the bFGF autophagy pathway validation group and bFGF+MHY1485 group than those in the bFGF+rapamycin group ( P<0.01), with higher LC3-II expression levels in the bFGF+MHY1485 group than those in the bFGF autophagy pathway validation group ( P<0.01). Conclusion:bFGF can improve the pathological state, motor behavior, and neuroelectrophysiological function in rats with spinal cord injury, for which the mechanism of action may involve downregulating cellular autophagy function by activating the mTOR pathway, thereby inhibiting excessive autophagy to promote neuronal regeneration and repair.

Allergen-specific immunotherapy(AIT) remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis(AR). Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group(CRRCG) convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.
