ObjectiveThis paper aims to explore the risk factors for chronic atrophic gastritis (CAG) with turbidity toxin accumulation syndrome and establish a prediction model. MethodsClinical data of 180 patients with CAG who participated in the "clinical study of Xianglian Huazhuo Particles blocking CAG cancer transformation" of Hebei Sheng Zhong Yi Yuan from July 2021 to March 2022 were collected. After confounding factors were controlled by propensity score matching, patients were divided into a training set (namely dev) and a validation set (namely vad) in a seven to three ratio. The risk factors for CAG with turbidity toxin accumulation syndrome in the training set were investigated by using univariate Logistic regression analysis and least absolute shrinkage and selection operator (namely Lasso) regression algorithms. Subsequently, a model, named model 1se, was developed by using the training set data to predict the risk factors for CAG with turbidity toxin accumulation syndrome. The accuracy of the prediction model was assessed by using various methods, including the receiver operating characteristic (ROC) curve, Hosmer-Lemeshow test (H-L), calibration plot, and decision curve analysis (DCA). ResultsAge, body mass index (BMI), family history of cancer, job and life satisfaction, yellow and greasy fur with slippery pulse, and heavy body sensation were independent risk factors of the model. The prediction model showed excellent predictive value for both the training and validation sets. ConclusionThe established prediction model for CAG with turbidity toxin accumulation syndrome has high discrimination and excellent calibration, which could provide an excellent clinical basis for disease diagnosis and individualized treatment of patients.

ObjectiveThis paper aims to explore the action and molecular mechanism of modified Tongluo Tangtai Formula(MTLTT) on myelin damage in diabetic peripheral neuropathy (DPN) based on network pharmacology and in vitro experiments. MethodsThe chemical components of the MTLTT were retrieved from the Traditional Chinese Medicine Systems Pharmacology (TCMSP) database and literature, and the component targets were collected from the SwissTargetPrediction database. The targets of DPN were collected from the GeneCards, OMIM, Disgenet, and GEO databases. Gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analyses were performed using the Metascape database, and a network diagram was constructed using Cytoscape software. The binding actions of core components with glycogen synthase kinase 3 beta (GSK-3β) and β-catenin were analyzed by Autodock Vina. An in vitro DPN model was established by high glucose-induced Schwann cells and dorsal root ganglion cells (SCs/DRGs). The ultrastructural morphological changes of SCs and DRGs were observed by scanning electron microscope(SEM), and the expressions of myelin-associated glycoprotein (MAG) and myelin basic protein (MBP) were detected by immunofluorescence staining. The mRNA and protein expression levels of MAG, MBP, myelin protein 0 (P0), peripheral myelin protein 22 (PMP22), and Wnt/β-catenin signaling pathway-related protein β-catenin, GSK-3β, Wnt family member 3α (Wnt3α), and Wnt inhibitory factor-1 (Wif-1) were detected by real-time polymerase chain reaction (Real-time PCR) and Western blot. ResultsNetwork pharmacology analysis revealed that MTLTT components may treat DPN via the Wnt signaling pathway, involving key proteins such as GSK-3β, β-catenin and Wif-1. The molecular docking results indicate that atropine, apigenin, baicalein, isoflavanone, and albiflorin have good binding activity with GSK-3β, and that all 13 core components have stable binding activity with β-catenin. Cell experiments showed that compared with the blank group, SCs and DRGs in the model group exhibited severe morphological and structural abnormalities such as disintegration, shrinkage and axonal rupture, while these abnormal changes were improved after MTLTT intervention. Immunofluorescence results indicated that the fluorescence intensity of MAG and MBP was markedly decreased in the model group relative to the blank group(P<0.01), while MTLTT treatment obviously upregulated the expression of MAG and MBP compared with the model group (P<0.01). Real-time PCR and Western blot assays revealed that the expression levels of myelin-related molecules MAG, MBP, P0 and PMP22 were significantly reduced in the model group (P<0.05,P<0.01), and MTLTT remarkably increased their expression levels (P<0.05). In the Wnt/β-catenin signaling pathway, the mRNA levels of GSK-3β, Wif-1 and Wnt3α were elevated and β-catenin mRNA expression was declined in the model group (P<0.01). Meanwhile, the protein expressions of GSK-3β and Wif-1 were upregulated, whereas those of Wnt3α and β-catenin were downregulated (P<0.01). Compared with the model group, MTLTT at different doses reduced the mRNA and protein levels of GSK-3β and Wif-1 to varying degrees (P<0.05), and distinctly enhanced the protein expression of Wnt3α and β-catenin(P<0.01). ConclusionMTLTT can alleviate high glucose-induced myelin damage. Its protective mechanism may promote myelin repair by upregulating the expression of MAG, MBP, P0 and PMP22, and the therapeutic effect is possibly associated with the activation of Wnt/β-catenin signaling pathway.

BackgroundThe global prevalence of depressive disorders is high, with a significant treatment gap remaining. Escitalopram oxalate, as a commonly used antidepressant in clinical practice, has a single target and is prone to cause adverse reactions such as gastrointestinal discomfort. The traditional Mongolian medicine Zadi-5 pills has a multi-target anti-depression mechanism and unique advantages such as improving the intestinal flora. However, there is currently a lack of randomized controlled trial evidence for the combined treatment of first-episode depression, along with insufficient research on its metabolic safety and potential drug interactions. ObjectiveTo explore the efficacy and safety of Zadi-5 pills combined with escitalopram oxalate in the treatment of the first-episode depression, so as to provide references for Mongolian medicine in depression management. MethodsA randomized controlled trial was conducted. A total of 103 patients with first-episode depression who were treated in the outpatient or inpatient departments of the Inner Mongolia Autonomous Region Mental Health Center from January 2023 to December 2024 and met the diagnostic criteria for depressive episode as defined in International Classification of Diseases, tenth edition (ICD-10) were included. Random numbers were generated using the RAND function in Excel software, and the patients were divided into the study group (n=52) and the control group (n=51). Both groups received escitalopram oxalate treatment, starting from 5 mg/d and gradually increasing to 20 mg/d. The study group additionally received Zadi-5 pills, 13 pills per day. The treatment duration for both groups was 6 weeks. Before treatment and at the 2nd, 4th, and 6th weeks of treatment, the severity of depressive symptoms was evaluated using the Hamilton Depression Scale-24 item (HAMD-24). At these time points, blood was collected on an empty stomach at 7∶00 for the detection of liver function (aspartate aminotransferase, alanine aminotransferase), triglycerides, and the blood concentration of escitalopram oxalate. ResultsA total of 100 patients completed the study, with 50 cases in the study group and the control group. The results of the repeated measures ANOVA showed that the interaction effect between group and time in the HAMD-24 score was statistically significant (F interaction= 18.070, P<0.01). At the end of the 4th and 6th weeks of treatment, the HAMD-24 score of the study group was lower than those of the control group (P<0.05). At each time point after treatment, the reduction rate of the HAMD-24 score in the study group was higher than those of the control group, and the differences were all statistically significant (P<0.05). The interaction effect between the triglyceride level groups and time was statistically significant (Finteraction=3.381, P<0.05).After treatment, the triglyceride levels in the study group showed a downward trend, while those in the control group showed an upward trend. There was no statistically significant interaction effect between the groups and time for liver function (aspartate aminotransferase and alanine aminotransferase) and the blood concentration of escitalopram oxalate (P>0.05). ConclusionCompared with escitalopram oxalate treatment alone, the combination of Zadi-5 pills and escitalopram oxalate is more effective in treating the first-episode depression, without increasing the risk of liver damage. The combined medication may have a potential beneficial effect on lipid metabolism. [Funded by Inner Mongolia Autonomous Region Health Science and Technology Planning Project (number, 202202107)]

Ischemic stroke (IS) is a serious cerebrovascular disease with high clinical incidence. Cerebral ischemia and hypoxia can induce metabolic reprogramming of cellular glycolysis. Hypoxia-inducible factor-1α (HIF-1α) serves as the core transcription factor in the hypoxic response. This article systematically reviews the molecular mechanisms of HIF-1α-mediated glycolytic reprogramming, elaborates on the effects of this metabolic alteration on the functional status of different immune cells, and summarizes the research progress of traditional Chinese medicine (TCM) interventions in this pathological process. HIF-1α reshapes glucose metabolic flux and shifts cellular metabolism toward glycolysis by regulating the transcription of key genes, including glucose transporters, glycolytic rate-limiting enzymes, and mitochondrial oxidative inhibitors. This metabolic disturbance can regulate the activation status, phenotypic differentiation, and functional remodeling of microglia, astrocytes, and peripherally infiltrated immune cells, thereby participating in the mediation of neuroinflammatory responses after IS. Moreover, multiple signaling pathways and the metabolite of glycolysis lactate can exert feedback regulation on this metabolic-immune process. Various active components of TCM and herbal formulas, such as astragaloside Ⅳ, salvianolic acid C, Ginkgo biloba extract, and Mailuo shutong pills, can inhibit abnormal glycolysis, reduce lactate accumulation, and restore the homeostasis of glucose oxidative metabolism by regulating signaling pathways including AMP-activated protein kinase/mammalian target of rapamycin/HIF-1α, HIF-1α/pyruvate kinase M2, and HIF-1α/lactate dehydrogenase A. Consequently, they effectively alleviate neuroimmune inflammation and attenuate ischemic brain injury.

ObjectiveTo investigate the mechanism by which Xianglian Huazhuo prescription (XLHZ) ameliorates chronic atrophic gastritis (CAG) through regulating glycolysis via the microRNA-34b-5p (miR-34b-5p)/6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 1 (PFKFB1) signaling pathway. MethodsBioinformatic screening was performed to identify the target genes of miR-34b-5p. In the animal experiments, a mouse model of CAG was established through a combination of N-methyl-N′-nitro-N-nitrosoguanidine (MNNG), ranitidine, and irregular feeding. The mice were randomized into the following groups: normal, model, Morodan group (2 g·kg-1), and high-, medium-, and low-dose XLHZ groups(7.2,3.8,1.9 g·kg-1). In the cell experiments, GES-1 cells were treated with MNNG for the modeling of CAG and grouped as follows: GES-1, MNNG+GES-1, MNNG+GES-1+XLHZ(10%), MNNG+GES-1+miR-34b-5p mimics, MNNG+GES-1+miR-34b-5p inhibitor, MNNG+GES-1+PFKFB1 inhibitor, and MNNG+GES-1+PFKFB1 mimics+XLHZ(10%). The general conditions of mice were observed. Real-time PCR was adopted to measure the expression levels of miRNA-34b-5p and PFKFB1 mRNA in the gastric mucosa of mice in each group. Dual luciferase reporter gene was used to verify the targeting interaction between miR-34b-5p and PFKFB1 in GES-1 cells exposed to MNNG. The cell-counting kit-8 (CCK-8) was used to screen the drug-containing serum concentration. Real-time PCR was employed to verify the transfection efficiency. Fluorescent probes were used to detect the expression and nuclear translocation of hypoxia-inducible factor-1α (HIF-1α) in each group of cells. The protein levels of HIF-1α, hexokinase 2 (HK2), PFKFB1, phosphofructokinase 1 (PFK1), and lactate dehydrogenase (LDHA) in the gastric mucosa of mice were determined by Western blot. The levels of glucose consumption and lactate in the serum and cells were measured by biochemical methods. Enzyme-linked immunosorbent assay (ELISA) was adopted to measure the content of adenosine triphosphate (ATP) in the gastric mucosa tissue and cells. ResultsThe animal experiments showed that compared with the normal group, the model group exhibited symptoms including mental fatigue, lethargy, sparse and dull fur, a tendency to curl up, sluggish responses, reduced food and water intake, and slow body weight gain. In addition, the model group showed decreased expression of miRNA-34b-5p (P<0.01), increased mRNA level of PFKFB1 (P<0.01), upregulated protein levels of HIF-1α, HK2, PFKFB1, PFK1, and LDHA (P<0.01), and increased glucose consumption, lactate content, and ATP content (P<0.01). Compared with the model group, the XLHZ group and Morodan group showed improved mental state, gradually improved fur, increased activity, food and water intake, and body weight. HE showed that each treatment group exhibited well arranged and increased gastric mucosal glands, reduced inflammatory cells, and recovered gastric pits. Transmission electron microscopy showed that the size of mitochondria in each treatment group returned to normal, with no obvious irregular shape, complete and clear cristae, and uniform matrix. Furthermore, each treatment group showed increased expression of miRNA-34b-5p (P<0.05), reduced mRNA level of PFKFB1 (P<0.05), downregulated protein levels of HIF-1α, HK2, PFKFB1, PFK1, and LDHA (P<0.05), and decreased glucose consumption, lactic acid, and ATP (P<0.05). The cell experiments showed that the expression and nuclear translocation of HIF-1α were reduced in all groups after treatment (P<0.05). The cell transfection efficiency was satisfactory (P<0.05). miR-34b-5p exhibited an effect comparable to that of XLHZ, effectively inhibiting glycolysis, whereas PFKFB1 promoted glycolysis and reversed the protective effect of XLHZ in CAG mice (P<0.05). ConclusionXLHZ could regulate the miR-34b-5p/PFKFB1 axis to inhibit glycolysis, thereby ameliorating MNNG-induced gastric mucosal atrophy.

ObjectiveTo investigate the mechanism by which Shengjiang Pingchuan Zhike pills (SPZP) alleviate airway injury in the rat model of cough variant asthma (CVA) via regulating autophagy through activating the adenosine monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR)/Unc-51-like autophagy activating kinase 1 (ULK1) signaling pathway based on transcriptomics, thus providing experimental evidence for the clinical application of SPZP. MethodsForty SPF-grade SD rats were enrolled in the present study and randomly via the random number table method assigned into four groups: a blank group, a model group, a SPZP (2 160 mg·kg-1·d-1) group, and a positive drug (montelukast sodium, MTL, 0.9 mg·kg-1·d-1)group, with 10 rats in each group. After one week of adaptive feeding, the rat model of cough variant asthma (CVA) was established by two-week sensitization with ovalbumin (OVA) and aluminium hydroxide, followed by capsaicin atomization challenge. Rats in the blank group received an equal volume of normal saline during modeling. Upon successful modeling, rats in the SPZP group and positive drug group were administrated with SPZP suspension and MTL solution, respectively, while those in the blank and model groups received the same dose of normal saline by gavage. The whole intervention lasted for 21 consecutive days. After the intervention, general behaviors of rats in each group were observed. Pulmonary function indicators were subsequently detected. Hematoxylin-eosin (HE) staining was performed to visualize the pathological morphology of the lung tissue, and periodic acid-Schiff (PAS) staining was adopted to evaluate airway mucus secretion. Transcriptomic sequencing was conducted to screen differentially expressed genes in the lung tissue across groups. The levels of inflammatory cytokines including interleukin (IL)-4, IL-5, immunoglobulin E (IgE), and interferon-γ (IFN-γ) in the bronchoalveolar lavage fluid (BALF) were quantified by enzyme-linked immunosorbent assay (ELISA). Immunofluorescence staining was used for detecting the co-localization of autophagy-related protein Beclin-1 and phosphorylated mammalian target of rapamycin (p-mTOR). Transmission electron microscopy was employed to count autophagosomes and observe mitochondrial morphological changes in the lung tissue. Western blot assay was utilized to measure the expression levels of AMPK/mTOR/ULK1 axis-related proteins, including AMPK, phosphorylated adenosine monophosphate-activated protein kinase (p-AMPK), mTOR, phosphorylated mammalian target of rapamycin (p-mTOR), ULK1, and phosphorylated Unc-51-like autophagy activating kinase 1 (p-ULK1) as well as the autophagy biomarkers Beclin-1 and selective autophagy adaptor protein p62 in lung specimens. ResultsCompared with the blank group, the model group exhibited markedly elevated cough frequency accompanied by wheezing and stridor, dull fur, poor mental activity, diminished motor activity, accelerated respiratory rate, and weakened sensory response and mobility to external stimuli, accompanied by a declining tendency of body mass. Meanwhile, the model group exhibited decreased dynamic lung compliance, increased airway resistance (P<0.01), severe pathological damage and excessive mucus secretion in the lung tissue (P<0.01), and elevated levels of IL-4, IL-5, and IgE and declined level of IFN-γ in the BALF (P<0.01). Ultrastructural observation revealed damaged mitochondrial morphology and a sharp reduction in the number of autophagosomes in the lung tissue. In addition, the expression of p-AMPK, p-ULK1, and Beclin-1 were downregulated, whereas p-mTOR and p62 were highly expressed (P<0.05, P<0.01) in the model group. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses demonstrated significant enrichment of AMPK, mTOR, and autophagy-related pathways. Compared with the model group, both the positive drug group and SPZP group obtained visible improvements in general behavioral manifestations and obvious recovery of pulmonary function indicators (P<0.05), alleviated pulmonary pathological lesions and suppressed excessive airway mucus secretion (P<0.05), recovered levels of inflammatory cytokines in the BALF (P<0.05), restored mitochondrial morphology, increased autophagosomes, upregulated expression levels of p-AMPK, p-ULK1, and Beclin-1, and downregulated expression levels of p-mTOR and p62 (P<0.05). ConclusionSPZP can effectively ameliorate airway inflammation and improve the pulmonary function in the rat model of CVA by activating the AMPK/mTOR/ULK1 signaling pathway, enhancing autophagy in the lung tissue, and inhibiting excessive airway mucus secretion and immune inflammatory imbalance.
