ObjectiveTo investigate the potential mechanism of heat-sensitive moxibustion on chronic atrophic gastritis (CAG) through the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) signaling pathway. MethodsFifty-eight SD rats were randomly divided into blank group (n=14) and modeling group (n=44). Rats in the blank group were fed routinely, while the rats in the modeling group received drinking water containing 1-methyl-3-nitro-1-nitrosoguanidine (MNNG) at a concentration of 140 μg/ml, combined with irregular fasting and feeding for 12 weeks to establish CAG model. After successful modeling, the rats were randomly divided into model group (n=10), inhibitor group (n=10) and moxibustion group (n=20). After 40 minutes of suspended moxibustion at "Zhongwan" (CV 12) daily, the rats in the moxibustion group were divided into heat-sensitive moxibustion group (n=10) and non-heat-sensitive moxibustion group (n=9) according to the change of tail temperature during moxibustion. The inhibitor group was bound for 40 minutes daily, and then administered with PI3K/Akt signaling pathway inhibitor, rapamycin solution, by gavage at a dose of 1 mg/kg. The model group received intragastric administration of 1 ml/kg normal saline after 40 minutes of restraint stress each day. All interventions were administered once daily for 28 consecutive days, while the blank group received no intervention. After the intervention finished, the body weight of rats in each group was compared. HE staining was used to observe the histopathological changes of gastric mucosa. The apoptosis-positive rate of gastric mucosal cells was detected by TUNEL assay. Immunohistochemistry was performed to determine the protein levels of matric metalloproteinase-7 (MMP7), vascular endothelial growth factor A (VEGFA) and epidermal growth factor receptor (EGFR) in gastric mucosa. The mRNA expression levels of PI3K, Akt and mammalian target of rapamycin (mTOR) in gastric mucosal tissues were detected by qPCR. The protein levels of phosphorylated Akt (p-Akt) and phosphorylated mTOR (p-mTOR) in rat gastric mucosal tissues were measured by Western Blotting. ResultsCompared to the blank group, rats in all other groups exhibited decreased body weight, significantly increased gastric mucosal cell apoptosis-positive rates, elevated protein levels of MMP7, VEGFA and EGFR in gastric mucosa, increased mRNA expression levels of PI3K, Akt and mTOR, and enhanced protein expression levels of p-Akt and p-mTOR (P<0.05 or P<0.01). Histopathological examination revealed thinning of the gastric mucosa, glandular disorganization and atrophy, accompanied by intestinal metaplasia.Compared to the model group, the heat-sensitive moxibustion group, the non-heat-sensitive moxibustion group and the inhibitor group all showed significant improvements in the above-mentioned indicators (P<0.05 or P<0.01). Compared to the heat-sensitive moxibustion group, the non-heat-sensitive moxibustion group and the inhibitor group exhibited increased positive rates of gastric mucosal cell apoptosis; the non-heat-sensitive moxibustion group showed increased protein levels of MMP7, VEGFA and EGFR, as well as mRNA expression levels of PI3K, Akt and mTOR, and protein expressions of p-Akt and p-mTOR; the inhibitor group exhibited elevated protein expression level of EGFR (P<0.05 or P<0.01). Histopathological examination showed that the gastric mucosal glands in the heat-sensitive moxibustion group were arranged more regularly, with an approximately normal structural appearance. ConclusionHeat-sensitive moxibustion can improve the body weight of CAG rats and repair gastric mucosal injury. Its therapeutic effects may be mediated by inhibiting excessive activation of gastric mucosal PI3K/Akt signaling pathway, thereby reducing gastric mucosal cell apoptosis.

Inflammatory bowel disease (IBD) is a chronic inflammatory disease that occurs in the gastrointestinal tract and adversely affects the quality of life of patients and the healthcare burden on society. Currently, drug therapy alone can achieve clinical remission in some patients, but it cannot break through the ceiling of what can be achieved with current therapies, and new therapeutic options still need to be found. Neuro-immunity-inflammation is closely related to each other, and the potential role of neuroelectric stimulation in modulating inflammatory response has made it a hot spot in the study of IBD treatment. However, the intrinsic mechanism of action is still unexplained and needs to be explored by further studies. This review discusses the role and mechanisms of vagus nerve electrical stimulation, sacral nerve electrical stimulation, tibial nerve electrical stimulation and other neuromodulation methods.

Objective:To evaluate the efficacy of corticosteroids in male children with Duchenne muscular dystrophy (DMD), and provide evidence for the rational clinical use of medication.Methods:This was a multicenter medical record series study which conducted from January 15 th to March 14 th, 2025. A total of 53 male children with DMD admitted to the Department of Rehabilitation of Children′s Hospital, Zhejiang University School of Medicine, Children′s Hospital of Chongqing Medical University and Affiliated Children′s Hospital of Soochow University from 2020 to 2024 were enrolled. Clinical data, corticosteroid usage, and the follow-up data were collected. The North star ambulatory assessment (NSAA) was used as the primary efficacy indicator. Generalized estimating equations (GEE) exchangeable working matrices were used for longitudinal analysis, and the least squares mean were used to compare the change trend of the efficacy evaluation index across different medication durations. Results:The age at the initiation of corticosteroid treatment was (6.3±1.9) years. The follow-up duration was 1.2 (0.9, 2.2) years. After treatment, the raw scores and linear scores of NSAA were both significantly higher than those before treatment ((22±7) vs. (19±5) points, (60±16) vs. (53±8) points; t=3.98, 3.69; both P<0.001). The 10 meter running time and time rising from floor were both shorter than those before treatment (6 (4, 8) vs. 7 (6, 9) s, 5 (3, 6) vs. 6 (5, 9) s; Z=2.62, 3.47; both P<0.01). GEE model analysis revealed all nonlinear correlation between motor function (NSAA linear score, 10-meter running velocity, and rising from floor velocity) and the duration of corticosteroid treatment (all P<0.05). Least squares mean comparison all showed that the medication effect first increased and then decreased with duration, reaching the peak at 1.1-2.0 years after treatment (all P<0.05). Conclusions:Corticosteroids can improve the motor function in male children with DMD, with the maximum treatment effect occurring 1 to 2 years after the initiation of treatment. It is necessary to comprehensively leverage time-varying efficacy of corticosteroids to optimize individualized treatment regimens for maximal motor function benefits in children with DMD.

This study was aimed at investigating the effectiveness of various host nucleic acid removal and non-specific amplifica-tion techniques in animal tissue samples,to increase the accuracy of pathogen identification in tissue samples.Simulated samples were prepared with a mixture of mouse lung tissue homogenates and Klebsiella pneumoniae fluids,and processed with six host nucleic acid removal kits and three non-specific amplification techniques.The effectiveness of each method in removing host DNA and enriching nucleic acids of pathogenic microorganisms was evaluated through real-time fluorescence quantitative PCR and high-throughput se-quencing.For host nucleic acid removal techniques,the method of selective cleavage and quantitative degradation of host DNA(Com-plete5 kit)effectively decreased the host nucleic acid content in tissue samples and increased the relative abundance of pathogen nucleic acids.In contrast,the magnetic bead method for host DNA removal(Next microbiome DNA enrichment Kit kit)was less effec-tive.At lower pathogen concentrations(77 CFU/mL),the Vazyme kit was more effective than the other kits in removing host nucleic acids.Non-specific amplification techniques(MALBAC whole genome amplification,MDA isothermal amplification,and random primer amplification)were not applicable to tissue samples and were not effective in increasing the relative abundance of pathogen nucleic acids.Selective lysis and quantitative degradation of host DNA were suitable for processing tissue samples with high host back-ground and low pathogenic microorganism levels,whereas non-specific amplification methods were not applicable to tissue samples for pre-processing of macro-genome high-throughput sequencing.
