ObjectiveCleft palate (CP) is a common congenital deformity often associated with velopharyngeal insufficiency (VPI), which disrupts the physiological coupling between respiration and speech. Conventional clinical assessments, such as nasometry and spirometry, provide limited static data and fail to visualize the dynamic spatiotemporal distribution of lung ventilation during phonation. This study introduces spatiotemporal electrical impedance tomography (ST-EIT) to evaluate speech-respiratory functional features in CP patients compared to normal controls (NC). The aim is to characterize multi-domain respiratory patterns and to validate an interpretable machine learning framework for providing objective, quantitative evidence for clinical assessment. MethodsSeventy-five participants were enrolled in this study, comprising 37 patients with surgically repaired CP and 38 healthy volunteers matched for age, gender, and body mass index (BMI). All subjects performed standardized sustained phonation tasks while undergoing synchronous monitoring with a 16-electrode EIT system and a pneumotachograph. A comprehensive feature engineering pipeline was developed to extract physiological parameters across 3 complementary domains. (1) Temporal domain: including inspiratory/expiratory phase duration (tPhase), time constants (Tau), and inspiratory-to-expiratory time ratios (TI/TE); (2) airflow domain: comprising mean flow, peak flow, and instantaneous flow at 25%, 50%, and 75% of tidal volume; and (3) spatial domain: quantifying global and regional tidal impedance variation (TIV), global inhomogeneity (GI), and center of ventilation (CoV). Extreme Gradient Boosting (XGBoost) classifiers were trained using 5 distinct data sources (Spirometry, Nasometry, Inspiratory-EIT, Expiratory-EIT, and fused ST-EIT). Model performance was rigorously evaluated via stratified 5-fold cross-validation, and Shapley additive explanations (SHAP) were employed to quantify global and local feature contributions. ResultsThe CP group exhibited a distinct respiratory phenotype compared to controls. In the temporal domain, CP patients showed significantly shorter inspiratory (1.60 s vs.1.85 s, P<0.001) and expiratory phase durations (2.45 s vs. 3.95 s, P<0.001), indicating a rapid, shallow breathing rhythm. In the airflow domain, while inspiratory flows were comparable, the CP group demonstrated significantly elevated mean and peak flows during the expiratory phase (P<0.001), reflecting compensatory respiratory effort. Spatially, CP patients presented significant ventilation redistribution, characterized by higher regional TIV in the right-anterior (ROI1) and left-posterior (ROI4) quadrants, but lower TIV in the left-anterior (ROI2) quadrant. In terms of diagnostic accuracy, the multi-modal ST-EIT model achieved the highest performance (AUC: 0.915±0.012, Accuracy: 0.843±0.019, F1-score: 0.872±0.017), substantially outperforming models based on spirometry (AUC: 0.721) or nasometry (AUC: 0.625) alone. Interpretability analysis revealed that spatial domain features were the most critical, contributing 53.4% to the model’s decision-making, followed by temporal (25.0%) and airflow (21.6%) features. ConclusionST-EIT successfully captures the temporal, airflow, and spatial deviations in CP speech respiration that are undetectable by conventional methods—specifically, rapid phase transitions, hyperdynamic expiratory airflow, and regional ventilation heterogeneity. This study validates ST-EIT as a robust, non-invasive, and radiation-free tool for characterizing speech-respiratory dysfunction, offering high clinical value for bedside screening, rehabilitation planning, and longitudinal monitoring of patients with cleft palate.

ObjectiveTo investigate the mechanism by which Shaoyaotang regulates the miRNA-155-mediated suppressor of cytokine signaling 1 (SOCS1)/Janus kinase 1 (JAK1)/signal transducer and activator of transcription 1 (STAT1) signaling pathway and thereby affects macrophage polarization. MethodsThe cell-counting kit-8 (CCK-8) assay was used to detect the effect of drug-containing serum of Shaoyaotang at different concentrations on the viability of RAW 264.7 cells. A cell model of inflammation was established by stimulating RAW264.7 cells with lipopolysaccharide (LPS) at a concentration of 10 mg·L-1 The modeled cells were assigned by the random number table method into seven groups: LPS-induced M1 polarization (model), M1+miRNA-155 mimics, M1+miRNA-155 inhibitor, M1+Shaoyaotang-containing serum, M1+miRNA-155 mimics+Shaoyaotang-containing serum, M1+miRNA-155 inhibitor+Shaoyaotang-containing serum, and M1+blank serum. Enzyme-linked immunosorbent assay was employed to measure the levels of inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β)]. Immunofluorescence assay was used to detect the expression of macrophage polarization markers [inducible nitric oxide synthase (iNOS) and macrophage mannose receptor 1 (CD206)]. Real-time PCR was employed to measure the expression of miRNA-155 in cells. Western blot was performed to determine the protein levels of SOCS1, STAT1, and JAK1. ResultsCompared with the LPS-induced M1 polarization (model) group, the M1+miRNA-155 mimics group showed up-regulated expression of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS (P<0.05) and down-regulated expression of CD206 (P<0.05). In both the M1+miRNA-155 inhibitor group and the M1+Shaoyaotang-containing serum group, the expression levels of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS were down-regulated (P<0.05), while those of SOCS1 and CD206 were up-regulated (P<0.05). Compared with the M1+miRNA-155 mimics group, the M1+miRNA-155 mimics+Shaoyaotang-containing serum group showed down-regulated expression of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS (P<0.05) and up-regulated expression of SOCS1 and CD206 (P<0.05). Compared with the M1+miRNA-155 inhibitor group, the M1+miRNA-155 inhibitor+Shaoyaotang-containing serum group showed down-regulated expression of miRNA-155, JAK1, STAT1, TNF-α, IL-6, IL-1β, and iNOS (P<0.05) and up-regulated expression of SOCS1 and CD206 (P<0.05). ConclusionShaoyaotang regulates macrophage polarization by modulating miRNA-155 expression and interfering with the SOCS1/JAK1/STAT1 signaling pathway. The findings provide new experimental evidence for the treatment of ulcerative colitis with Shaoyaotang.

ObjectiveTo investigate the potential role and underlying mechanisms of Shaoyaotang in intervening macrophage glycolytic reprogramming in ulcerative colitis (UC). MethodsForty-eight C57BL/6 mice were randomly divided into six groups: Normal control group, model group, mesalazine group (0.39 g·kg-1), Shaoyaotang group (15.54 g·kg-1), 2-deoxy-D-glucose (2-DG) group (glycolysis inhibitor, 100 mg·kg-1), and 2-DG + Shaoyaotang combined group (100 mg·kg-1+15.54 g·kg-1). Except for the normal control group, mice in the other five groups were induced to establish UC models using dextran sulfate sodium (DSS). The normal control group was administered pure water via intragastric gavage, while the other groups received intragastric gavage of mesalazine solution, intragastric gavage of Shaoyaotang, and the 2-DG group was treated with 2-DG via intraperitoneal injection. After 7 consecutive days of treatment, colonic tissues were extracted. Hematoxylin and eosin (HE) staining was performed to evaluate histopathological changes and tissue injury in the colon. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α) in colonic tissues. Western blot analysis was employed to determine the expression levels of hypoxia-inducible factor-1α (HIF-1α), glucose transporter (GLUT1), lactate dehydrogenase A (LDHA), pyruvate kinase M2 (PKM2), and 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 (PFKFB3) in colonic tissues. Immunofluorescence was conducted to detect the expression of CD206 and inducible nitric oxide synthase (iNOS) in colonic tissues. Liquid chromatography-mass spectrometry (LC-MS) was utilized to measure lactate and citrate levels in colonic tissues. ResultsCompared with the normal control group, mice in the model group exhibited a significant increase in disease activity index (DAI) scores, accompanied by colonic mucosal congestion, edema, and inflammatory cell infiltration, significantly elevated expression of the inflammatory cytokine TNF-α (P<0.05), significantly decreased IL-10 expression (P<0.05), significantly increased levels of HIF-1α, GLUT1, LDHA, PKM2, and PFKFB3 in colonic tissues (P<0.05), markedly elevated iNOS expression (P<0.05), significantly decreased CD206 expression (P<0.05), and significantly elevated lactate and citrate levels in colonic tissues (P<0.05). In contrast to the model group, the Shaoyaotang group, inhibitor group, and Shaoyaotang combined with inhibitor group demonstrated amelioration of mucosal injury in colonic tissues, markely decreased expression levels of the inflammatory cytokine TNF-α (P<0.05), elevated IL-10 expression levels, significantly decreased expression of HIF-1α, GLUT1, LDHA, PKM2, and PFKFB3 (P<0.05), markedly reduced iNOS expression levels (P<0.05), significantly increased CD206 expression (P<0.05) and significantly decreased lactate and citrate levels (P<0.05). ConclusionShaoyaotang ameliorates symptoms of DSS-induced UC in mice, and its therapeutic mechanism may be associated with regulating macrophage glycolytic reprogramming via modulation of the HIF-1α signaling pathway.

ObjectiveTo investigate the role of microRNA-155-5p (miR-155-5p) in ulcerative colitis (UC) and study the molecular mechanism of Shaoyaotang in the treatment of UC by regulating miR-155-5p. MethodsForty-eight SPF-grade male C57BL/6 mice were selected and assigned via the random number table method into 6 groups (n=8): A blank control group, a model group, a mesalazine (0.39 g·kg-1) group, a Shaoyaotang (31.08 g·kg-1) group, a Janus kinase 1 (JAK1) inhibitor (baricitinib, 10 mg·kg-1) group, and a Shaoyaotang combined with inhibitor (baricitinib 10 mg·kg-1 + Shaoyaotang 31.08 g·kg-1) group. After successful modeling of UC by gavage of 3% dextran sulphate sodium solution, each group received corresponding drug intervention for 7 days. Shaoyaotang and mesalazine were administered by gavage, and baricitinib by intraperitoneal injection. Twenty-four hours after the last administration, mice were anesthetized by intraperitoneal injection of pentobarbital sodium, and blood was collected for determination of white blood cell count and erythrocyte sedimentation rate (ESR). Mice were then sacrificed for measurement of colon length. Hematoxylin-eosin staining was used to observe colonic pathological changes and perform pathological scoring. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was employed to determine the relative expression of miR-155-5p in the colonic tissue, and Western blot was used to determine the protein levels of JAK1, phosphorylated JAK1 (p-JAK1), suppressor of cytokine signaling 1 (SOCS1), signal transducer and activator of transcription 1 (STAT1), and phosphorylated STAT1 (p-STAT1). ResultsCompared with the blank control group, the model group showed increased disease activity index (DAI) score and pathological score, shortened colon, upregulated relative expression of miR-155-5p and protein levels of p-JAK1 and p-STAT1, downregulated protein level of SOCS1 in the colonic tissue, prolonged time of erythrocyte sedimentation, and increased white blood cell count (P<0.01). Compared with the model group, all drug-treated groups exhibited improvements in the above indicators (P<0.01). Moreover, the Shaoyaotang group showed better therapeutic effects than the mesalazine group in regulating miR-155-5p expression, related protein levels, DAI score, and colonic pathological score (P<0.01). ConclusionShaoyaotang may downregulate miR-155-5p to relieve its inhibition on SOCS1, thereby suppressing the excessive activation of the JAK1/STAT1 signaling pathway and ultimately alleviating intestinal inflammatory damage.

In recent years, as the incidence of ulcerative colitis (UC) is growing, intestinal mucosal injury has garnered increasing attention, and it is characterized by high recurrence, risk of inflammation-cancer transformation, and difficulty in repair. Intestinal mucosal injury in UC is centered on persistent inflammation and barrier dysfunction, with its pathological mechanisms involving endoplasmic reticulum stress (ERS)-mediated changes such as abnormal apoptosis, abnormal autophagy, and inflammatory responses. ERS induces apoptosis of intestinal epithelial cells, disrupts tight junction proteins, and exacerbates inflammatory responses through pathways such as protein kinase R-like endoplasmic reticulum kinase (PERK), inositol-requiring enzyme 1 alpha (IRE1α), and activating transcription factor 6 (ATF6), ultimately causing intestinal mucosal injury. Traditional Chinese medicine (TCM) has a long history of research on UC. The theory of sores depending on spleen-earth holds that spleen deficiency is the fundamental cause of UC, while pathological products such as dampness-turbidity and blood stasis are the secondary manifestations. Dysfunction of the spleen-earth leads to insufficient production and transformation of Qi and blood, malnutrition of the intestinal mucosa, and invasion of external pathogens. In the active phase of UC, spleen deficiency is often accompanied by excessive pathogenic factors such as dampness-heat and heat-toxin, leading to acute intestinal mucosal damage. In the remission phase, however, it is mainly characterized by spleen deficiency and healthy Qi deficiency, accompanied by residual pathogens, resulting in weak intestinal mucosal repair. Studies have shown that the endoplasmic reticulum, as a key site for protein synthesis and folding, has functions highly similar to the TCM concept of the spleen governing transportation and transformation. From a TCM perspective, the endoplasmic reticulum can be regarded as the carrier of spleen transportation, and ERS is a microcosmic manifestation of spleen dysfunction, leading to intestinal mucosal injury. ERS impairs the structure and function of the endoplasmic reticulum, induces the generation of abnormal Qi, and triggers pathological changes, making inflammation difficult to be reduced and causing the aggravation of ERS, forming a vicious cycle of spleen deficiency-pathological products-intestinal injury. TCM has unique advantages in regulating ERS to prevent and treat intestinal mucosal injury. According to the theory of sores depending on spleen-earth and the modern medical understanding of ERS, this paper delves into the TCM and Western medicine pathogenesis of intestinal mucosal injury in UC. Furthermore, this paper discusses the roles of TCM active components and compound formulas in reducing intestinal mucosal injury in UC by regulating ERS under the guidance of the treatment principles of invigorating the spleen and replenishing Qi as the key and dispelling dampness and removing blood stasis as the supplementation, aiming to provide new ideas and methods for the prevention and treatment of UC.

This paper aims to study the effect of Ziziphi Spinosae Semen extracts on chronic unpredictable mild stress(CUMS)-induced depression-like and insomnia behavior models of mice. The CUMS-induced depression-like and insomnia behavior model of mice was established by CUMS treatment for three weeks. The mice were randomly divided into control group, model group, positive drug diazepam group(2 mg·kg~(-1)), as well as low-dose group(1.95 g·kg~(-1)), medium-dose group(3.9 g·kg~(-1)), and high-dose group(7.8 g·kg~(-1)) of Ziziphi Spinosae Semen extracts, with 18 mice in each group. On the 15th day of modeling, the drug was administered intragastrically once a day for one week. Then, the pentobarbital sodium cooperative righting experiment, open field experiment, and elevated plus maze experiment were carried out, respectively. The contents of neurotransmitters 5-hydroxytryptamine(5-HT) and 5-hydroxyindoleacetic acid(5-HIAA) in serum and thalamus of mice, as well as the levels of corticotropin releasing hormone(CRH), adrenocorticotropic hormone(ACTH), and corticosterone(CORT) in serum, were determined by enzyme-linked immunosorbent assay(ELISA). The neuron damage in the hippocampus of mice was observed by hematoxylin-eosin(HE) staining and Nissl staining. Western blot was used to detect the expressions of tryptophan hydroxylase 2(TPH2), serotonin transporter(SERT), monoamine oxidase A(MAOA), five prime repressors under dual repression binding protein 1(Freud1), synaptic plasticity-related proteins [cellular gene FOS(C-FOS), postsynaptic density protein 95(PSD95), synapsin 1(SYN1), and activity-regulated cytoskeleton-associated gene(ARC)], blood-brain barrier(BBB) permeability-related proteins [zonula occludens 1(ZO-1), occludin, and claudin 1], inflammatory factors [NOD-, LRR-and pyrin domain-containing protein 3(NLRP3), apoptosis-associated speck-like protein(ASC), gasdermin D(GSDMD), caspase-3, and caspase-8], and antioxidant factors [nuclear factor erythroid 2-related factor 2(NRF2) and heme oxygenase 1(HO1)] in thalamic tissue of mice. The results indicated that compared with that in the model group, the sleep latency was significantly shortened, and the sleep duration was significantly prolonged in each dose group of Ziziphi Spinosae Semen extracts. The number of visits to the central area of the open field and the distance and time of visits were significantly increased in each dose group of Ziziphi Spinosae Semen extracts. In addition, the proportion of distance and time of entering the open arm area of the elevated plus maze was significantly increased in each dose group of Ziziphi Spinosae Semen extracts. The contents of 5-HT and 5-HIAA in serum and thalamus of mice increased to varying degrees in each dose group of Ziziphi Spinosae Semen extracts; the contents of CRH, ACTH, and CORT in serum of mice were significantly decreased. The protein expression of TPH2 was significantly increased. The protein expression of MAOA, SERT, and Freud1 was significantly decreased. Ziziphi Spinosae Semen extracts could also significantly reduce the protein expression of C-FOS but significantly increase the protein expression of PSD95, ARC, and SYN1. They could reduce the pathological damage of the hippocampus in mice and significantly increase the protein expression of ZO-1, occluding, and claudin 1. The protein expression of NLRP3, GSDMD, ASC, caspase-3, and caspase-8 in the thalamic tissue of mice was significantly decreased, and the protein expression of HO1 and NRF2 was significantly increased. In conclusion, Ziziphi Spinosae Semen extracts could effectively improve sleep disorders and depression-like behaviors in CUMS-induced model mice, which may be related to regulating the 5-HT anabolism process and hypothalamic-pituitary-adrenal(HPA) axis-related hormone levels, reducing pathological damage in the hippocampus, improving synaptic plasticity, repairing BBB integrity, and alleviating inflammatory response and oxidative stress damage.

Traditional Chinese medicine(TCM) is the pillar for the development of motherland medicine, and animal medicine has a long history of application in China, characterized by wide resources, strong activity, definite efficacy, and great benefits. It has significant potential and important status in the consumption market of raw materials of TCM. In the context of global climate change, farming system alterations, and low renewability, the depletion of wild medicinal animal resources has accelerated. Accordingly, the conservation and sustainable utilization of wild resources of animal medicinal materials has become a problem that garners increasing attention and urgently needs to be solved. This paper summarizes the current situation of domestic and foreign medicinal animal breeding and research progress in industrial application in recent years and points out the issues related to standardized breeding, germplasm selection and breeding, and quality evaluation standards for medicinal animals. Furthermore, this paper discusses standardized breeding, quality standards, resource protection and utilization, and the search for alternative resources for rare and endangered medicinal animals. It proposes that researchers should systematically carry out in-depth basic research on animal medicine, improve the breeding scale and level of medicinal animals, employ modern technology to enhance the quality standards of medicinal materials, and strengthen the research and development of alternative resources. This approach aims to effectively address the relationship between protection and utilization and make a significant contribution to the sustainable development of medicinal animal resources and the animal-based Chinese medicinal material industry.

In patients with chronic kidney disease(CKD),the incidence of cardiovascular events and the mortality rate are significantly higher than those in the general population.Approximately 85% of end-stage CKD patients develop hyperhomocysteinemia(HHcy)due to impaired renal function.It is not yet fully determined whether HHcy merely acts as a biomarker of CKD or plays a role in the pathogenesis.Although supplementation with folic acid and other B vitamins(B6 and B12)has been proven to lower the plasma level of total homocysteine,their effectiveness in slowing CKD progression or reducing cardiovascular complications remains uncertain.This article reviews the latest research progress in the relationship between HHcy and CKD,aiming to give new insights into the prevention and treatment of CKD and its complications.

The introduction of non-vitamin K antagonist oral anticoagulant (NOAC) into clinical use heralds a new age for anticoagulation therapy in patients with atrial fibrillation (AF).However,anticoagulation-related bleeding is currently a major challenge in the anticoagulation process.Assessing the risk of anticoagulation-related bleeding is an important part for the management of patients with AF.Clinical risk factor scores have moderate ability to predict the risk of anticoagulation-related bleeding.To improve the anticoagulation safety of NOACs,additional clinical and biological markers and genetic polymorphisms should be considered to enhance the predictive capability for anticoagulation-related bleeding.This review summarizes the challenges in the management of anticoagulation therapy,with emphases on the bleeding risk scores,biomarkers,clinical indicators,and genetic loci currently used to guide the risk assessment of anticoagulation-related bleeding in AF patients.This review is expected to provide research insights and reference frameworks for predicting and evaluating the bleeding risk associated with NOACs.
