OBJECTIVES: To investigate the therapeutic mechanism of Thesium chinense Turcz. (TCT) for antibiotic-associated diarrhea (AAD). METHODS: Network pharmacology, KEGG pathway enrichment analysis and molecular docking were used to identify the shared targets and genes of TCT and AAD, the key signaling pathways and the binding between the active components in TCT and the core protein targets. In a Kunming mouse model of AAD established by intragastric administration of lincomycin hydrochloride, the effects of daily gavage of 1% carboxymethyl cellulose sodium or TCT gel solutions at 1.5 g/kg and 3 g/kg (n=10) on body weight and diarrhea were observed. HE staining, ELISA, 16S rRNA sequencing, and Western blotting were used to examine pathologies, expression levels of IL-6 and TNF-α, changes in gut microbiota, and protein expressions of EGFR, p-EGFR, PI3K, p-PI3K, Akt, and p-Akt in the colon tissues of the mice. RESULTS: We identified a total of 66 active components of TCT and 68 core targets including EGFR, STAT3 and PIK3CA. KEGG pathway enrichment analysis suggested that the therapeutic effects of TCT was mediated primarily through the PI3K/Akt signaling pathway. Molecular docking showed that EGFR had the highest binding affinity with coniferin, and the EGFR-coniferin complex maintained a stable conformation at 10 ns, whose stability was also confirmed by Gibbs free energy analysis. In the mouse models of AAD, treatment with TCT significantly improved colonic tissue morphology, decreased colonic levels of TNF-α and IL-6, increased gut microbiota diversity, and modulated the relative abundances of the key genera including Lactobacillus and Bacteroides. TCT treatment also markedly reduced protein expressions of p-EGFR, p-PI3K and p-Akt in the colon tissues of the mice. CONCLUSIONS TCT can alleviate AAD in mice by modulating gut microbiota composition, regulating the EGFR/PI3K/Akt signaling pathway, and reducing TNF‑α and IL-6 expressions.

Objective:To investigate the role of pyroptosis in T-2 toxin induced articular cartilage injury.Methods:A total of 145 SPF grade male Wistar rats were randomly divided into blank control group ( n = 45), solvent control group ( n = 45), and T-2 toxin group ( n = 55) based on body weight (50 - 70 g). The T-2 toxin group and the solvent control group were given 100 ng·g -1·d -1 T-2 toxin and an equal amount of anhydrous ethanol by gavage, respectively; the blank control group was fed routinely. Fifteen rats from each group were euthanized at 6, 12, and 24 weeks of intervention, and bilateral knee joints of the rats were collected. Pathological changes in rat knee articular cartilage were observed using hematoxylin and eosin staining. TdT-mediated dUTP nick-end labeling (TUNEL) staining was used to detect chondrocyte injury. Western blot was used to detect the protein expression of gasdermin D (GSDMD), cleaved N-terminal of gasdermin D (GSDMD-N), NOD like receptor thermal protein domain associated protein 3 (NLRP3), cysteinyl aspartate specific proteinase 1 (Caspase-1), interleukin 1β (IL-1β), interleukin 18 (IL-18), and apoptosis-associated spike-like protein containing CARD (ASC). Results:At 6, 12, and 24 weeks of intervention, the T-2 toxin group rats showed varying degrees of damage to the knee articular cartilage tissue, including a decrease in the number of chondrocytes and death. At 24 weeks of intervention, the TUNEL staining positivity rates of chondrocytes in the blank control group, solvent control group, and T-2 toxin group were (1.28 ± 0.45)%, (0.73 ± 0.27)%, and (4.01 ± 2.37)%, respectively, with statistically significant differences between the groups ( F = 6.11, P = 0.036); and the T-2 toxin group was higher than the blank control group ( P < 0.05). At 24 weeks of intervention, there were statistically significant differences in the expression levels of NLRP3, Caspase-1, GSDMD, GSDMD-N, and IL-1β proteins among the blank control group, solvent control group, and T-2 toxin group ( F = 3.81, 11.81, 6.74, 3.71, 155.49, P = 0.044, 0.003, 0.023, 0.036, 0.001); and the T-2 toxin group was higher than the blank control group ( P < 0.05). At different intervention cycles, there was no statistically significant difference in the expression levels of ASC and IL-18 proteins among the groups ( F = 0.78, 0.93, 3.73, 2.26, 0.88, 0.11, P > 0.05). Conclusion:The NLRP3/Caspase-1/GSDMD pathway mediated pyroptosis is involved in T-2 toxin induced articular cartilage injury in rats.

Objective:To identify the risk factors for massive blood loss in pediatric patients with congenital scoliosis undergoing posterior hemivertebra resection.Methods:The clinical data of pediatric patients with congenital scoliosis who underwent posterior hemivertebra resection in our hospital from May 2017 to July 2019 were collected.The children were divided into group A (massive blood loss, blood loss/blood volume ≥30%) and group B (non-massive blood loss, blood loss/blood volume <30%) according to intraoperative blood loss.Logistic regression analysis was used to stratify the risk factors.Results:A total of 108 pediatric patients were enrolled in the study including 29 cases in group A and 79 cases in group B, respectively.There were significant differences in the preoperative Cobb angle, body mass index, the number of fused levels, the number of screws and operative time between the two groups ( P<0.05). Logistic regression analysis showed that the preoperative Cobb angle, operative time, the number of fused levels and body mass index were the risk factors for intraoperative massive blood loss ( P<0.05). Conclusion:Lower BMI, larger Cobb angle, increased operative time and more fused levels are the risk factors for massive blood loss in pediatric patients with congenital scoliosis undergoing posterior hemivertebra resection.
