BACKGROUND:Rev-erbα is involved in the regulation of inflammation,but pharmacological activation of Rev-erbα increases the risk for cardiovascular diseases.To reduce the relevant risk,an exploration on SR9009,a Rev-erbα agonist,combined with other drugs to relieve inflammation in skeletal myoblasts was conducted,laying the theoretical foundation for the treatment of inflammation-associated skeletal muscle atrophy. OBJECTIVE:To investigate the relationship of SR9009,indolepropionic acid and nuclear factor-κB signaling pathways in lipopolysaccharide-induced C2C12 myoblasts. METHODS:(1)C2C12 myoblasts were induced to differentiate in the presence of lipopolysaccharide(1 μg/mL).RNA-seq and KEGG pathway analysis were used to study signaling pathways.(2)C2C12 myoblast viability was assessed using the cell counting kit-8 assay to determine optimal concentrations of indolepropionic acid.Subsequently,cells were categorized into control group,lipopolysaccharide(1 μg/mL)group,SR9009(10 μmol/L)+lipopolysaccharide group,indolepropionic acid(80μmol/L)+lipopolysaccharide group,and SR9009+indolepropionic acid+lipopolysaccharide group.ELISA was employed to measure protein expression levels of interleukin-6 in the cultured supernatant.Real-time quantitative PCR were employed to measure mRNA expression levels of interleukin-6,tumor necrosis factor α,TLR4 and CD14.Western blot assay were employed to measure protein expression levels of NF-κB p65 and p-NF-κB p65.(3)After Rev-erbα was knocked down by siRNA,knockdown efficiency was assessed by RT-qPCR.And mRNA levels of interleukin-6 and tumor necrosis factor α were also measured. RESULTS AND CONCLUSION:Compared with the blank control group,lipopolysaccharide time-dependently inhibited myofibroblast fusion to form myotubes,the mRNA expression levels of interleukin-6 and tumor necrosis factor α were elevated,and the level of interleukin-6 in the cell supernatant was significantly increased.The results of KEGG pathway showed that the nuclear factor-κB signaling pathway was activated by lipopolysaccharide.Indolepropionic acid exhibited significant suppression of C2C12 myoblasts viability when its concentration exceeded 80 μmol/L.Indolepropionic acid and SR9009 inhibited the activation of NF-κB signaling pathway,thereby played an anti-inflammatory role,and suppressed the mRNA expression levels of interleukin-6,tumor necrosis factor α,TLR4 and CD14.Compared with the lipopolysaccharide group,the ratio of p-NF-κB p65/NF-κB p65 protein expression were downregulated.SR9009 combined with indolepropionic acid notably reduced lipopolysaccharide-induced inflammation,further downregulated the mRNA expression levels of interleukin-6,tumor necrosis factor α,TLR4 and CD14.The ratio of p-NF-κB p65/NF-κB p65 protein expression was significantly lower than that in the SR9009+lipopolysaccharide group or indolepropionic acid+lipopolysaccharide group.Rev-erbα increases time-dependently with lipopolysaccharide induction.The knockdown efficiency of Rev-erbα by siRNA reached over 58%,and lipopolysaccharide was added after Rev-erbα was successfully knocked down.Compared with the lipopolysaccharide group,the mRNA expression levels of interleukin-6 and tumor necrosis factor α were significantly up-regulated.These results conclude that Rev-erbα may act as a promising pharmacological target to reduce inflammation.SR9009 targeted activation of Rev-erbα combined with indolepropionic acid significantly inhibits the nuclear factor-κB signaling pathway and attenuates the inflammatory response of C2C12 myofibroblasts.Moreover,the combined anti-inflammatory effect is superior to that of the intervention alone.

ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia (Rhizoma Pinelliae)- Wutou (Aconitum) in the same formula, with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula, published from January 1st, 2014, to June 30th, 2023, was retrieved from databases including CNKI, VIP, Wanfang, SinoMed, PubMed, Cochrane Library, and Embase. A database was established, and information related to adverse reactions was extracted, including descriptions, classifications, specific manifestations, management and outcomes, patients' primary diseases (western medicine diseases and traditional Chinese medicine diagnoses and syndromes), and medication information (dosage, ratio, administration routes, and dosage forms). ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common, with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches, the adverse reaction relieved to extant, while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system, chronic bronchitis and chronic obstructive pulmonary disease (COPD) were most common, while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g, while for the Wutou, Fuzi (Radix Aconiti Lateralis Praeparata) was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi, with a 1∶1 ratio. The main administration route was oral, and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

Objective To analyze the causal relationship between immune cell phenotype and gastric cancer. Methods Bidirectional two-sample Mendelian randomization (MR) analysis was used to select 731 genetic variants involving immune cell phenotypes from the GWAS dataset as instrumental variables. Inverse-variance weighting method (IVW), weighted median method (WM), and MR-Egger regression were used for sensitivity analysis. Cochran Q test, MR-Egger regression, MR-PRESSO method, and remain-one method were also conducted. Results Changes in the absolute count of IgD+ B cells and CD14-CD16- cells were significantly associated with the risk of gastric cancer. A lower proportion of IgD+ B cells was associated with a lower risk of gastric cancer (OR=0.86, 95%CI: 0.79-0.94), while an increased number of CD4-CD8-T cells was associated with an increased risk of gastric cancer (OR=1.2, 95%CI: 1.1-1.3). Conclusion A causal relationship exists between immune cell phenotype and the risk of gastric cancer. Changes in specific immune markers may regulate the development of gastric cancer by affecting the tumor microenvironment.

ObjectiveTo construct an animal model of respiratory syncytial virus(RSV)-infected pneumonia suitable for preclinical studies. MethodsThe virulence of RSV to the four cell lines was observed by cytopathic effect (CPE), and 50% tissue culture infective dose(TCID50) was calculated. Twenty BALB/c mice were randomly divided into a normal group and a model group. Six BALB/c-hIGF1R mice served as the humanized IGF1R model group. Except for the normal group, the other groups received intranasal RSV infection on days 1 and 3 to establish a viral pneumonia model. The efficacy of establishing an RSV-induced pneumonia animal model based on humanized insulin-like growth factor 1 receptor (IGF1R) mice was evaluated by measuring organ indices, peripheral blood lymphocyte percentages, pulmonary pathology and imaging, and pulmonary viral load. Additionally, ten BALB/c mice served as normal group, and thirty-two BALB/c-hIGF1R mice were randomly assigned to humanized IGF1R model group, ribavirin group (82.5 mg·kg-¹·d-¹), and high and low dose groups of Lianhua Qingwen (3.3 mg·kg-¹·d-¹ , 1.65 mg·kg-¹·d-¹), with 8 mice per group. The viral load in lung tissue was measured after ribavirin and Lianhua Qingwen intervention, and the model was applied to the evaluation of anti-RSV drugs. ResultsIn the lungs of the humanized IGF1R model group, large solid and diffuse ground-glass shadows were seen, and the lung volume was significantly increased (P<0.01). The lung index was significantly increased (P<0.01), and both the spleen index and thymus index were significantly decreased (P<0.01). The percentages of CD3+ and CD4+T cells were significantly decreased (P<0.05), and there was a large amount of inflammation and stasis in the perivascular area of the lung tissue, which was predominantly characterized by lymphocytes. The endothelium of blood vessels was partially detached, with a small number of eosinophils. After infecting BALB/c-hIGF1R mice with RSV, the expression of viral nucleic acids in the lung tissue of the mice was significantly increased, with significant differences compared with the normal group (P<0.01). The expression of viral nucleic acids in the ribavirin group and the high and low dose groups of Lianhua Qingwen was significantly reduced, with significant differences compared with the normal group (P<0.01). ConclusionHumanized IGF1R mice are more susceptible to respiratory SVC, and the animal model of RSV-infected pneumonia based on humanized IGF1R mice was successfully constructed, which is suitable for the evaluation of anti-RSV drugs.

ObjectiveTo investigate the possible mechanism of Shufeng Jiedu capsules (SFJD) in alleviating influenza A (H1N1) virus pneumonia and focus on its effect on Toll-like receptor (TLR) signaling pathway in respiratory epithelial cells. MethodsA mouse model of viral pneumonia was established via the A/PR/8/34 (PR8) strain of influenza A virus. Mice were randomly divided into a normal group, a PR8 infection (PR8) group, and an SFJD group (8.4 g·kg-1), with 10 mice in each group. The day of infection was designated as day 1. The SFJD group was administered intragastrically at a volume of 20 mL·kg-1 daily, while the normal and PR8 groups were given an equal volume of deionized water. Micro-computed tomography (Micro-CT) was performed on day 5, and the mice were dissected to collect their lungs, after which the lung index was calculated to verify the therapeutic effect of SFJD. Single-cell sequencing was used to analyze the differentially expressed genes in respiratory epithelial cells. Multiplex fluorescence immunohistochemistry was employed to detect the expression of TLR, tumor necrosis factor receptor-associated factor 6 (TRAF6), and myeloid differentiation factor 88 (MyD88) proteins in epithelial cell adhesion molecule (EpCAM)-positive cells, and the proportion of respiratory epithelial cells expressing TLR pathway proteins was calculated. Respiratory epithelial cells were then sorted by flow cytometry, and Western blot was used to detect the expression of TLR, MyD88, TRAF6, Toll-interleukin receptor domain-containing adaptor inducing interferon-β (TRIF), inhibitor of κB kinase α (IKKα), and nuclear factor-κB (NF-κB) in the sorted epithelial cells. Enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in lung tissue. ResultsAt the transcriptional level, SFJD reversed the expression of TLR signaling pathway genes in respiratory epithelial cells, downregulating multiple TLR signaling pathway-related genes (P<0.01). At the protein level, SFJD significantly reduced the proportion of respiratory epithelial cells expressing TLR3 (P<0.05), the expression levels of TLR2, TLR3, TLR4, TRIF, TRAF6, IKKα, and NF-κB in epithelial cells(P<0.05, P<0.01), as well as the levels of pro-inflammatory cytokines IL-1β and TNF-α in lung tissue (P<0.01). ConclusionSFJD may alleviate viral pneumonia by suppressing the expression of TLR in respiratory epithelial cells and their subsequent signaling cascades.

Objective:To explore the effect of multidisciplinary management combined with 60-second high-risk diabetic foot screening in diabetic foot.Methods:From January to December 2022, 138 patients with diabetic foot were selected from Xinxiang Central Hospital by convenience sampling. The patients were randomly divided into a control group and an observation group, with 69 cases in each group. Control group implemented routine follow-up management of diabetic foot, and observation group carried out multidisciplinary management combined with 60-second high-risk diabetic foot screening on the basis of control group, and the intervention lasted for six months. The progress of Wagner grading of diabetic foot and foot self-care were compared between the two groups.Results:After intervention, the number of Wagner grading progression patients in observation group and control group was four cases (5.80%) and 10 cases (14.49%), respectively. The number of progression patients in observation group was less than that in control group, and the difference was statistically significant (χ 2=4.161, P=0.041). The total score and dimension scores of diabetic foot self-management in the two groups after the intervention were higher than those before the intervention, but only the scores of observation group before and after the intervention were statistically significant ( P<0.05). After intervention, the total score and dimension scores of diabetic foot self-management in observation group were higher than those in control group, with a statistically significant difference ( P<0.05) . Conclusions:Multidisciplinary management combined with 60-second high-risk diabetic foot screening can effectively delay the progress of diabetic foot and improve patients' foot self-care.
