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.

AIM:To investigate whether casein kinase 2(CK2)/calmodulin(CaM)/small-conductance Ca2+-activated K+channel type 2(SK2)signaling pathway mediates autophagy-induced sympathoexcitation in the paraventricu-lar nucleus(PVN)of rats with chronic heart failure(CHF).METHODS:We randomly divided 180 Wistar rats,aged 6 to 8 weeks,into 10 groups:sham+dimethyl sulfoxide(DMSO),sham+artificial cerebrospinal(aCSF),CHF+DMSO,CHF+aCSF,CHF+rapamycin(RAPA),CHF+3-methyladenine(3-MA),CHF+5,6-dichlorobenzimidazole riboside(DRB),CHF+calmidazolium chloride(CMDZ),CHF+N-cyclohexyl-N-[2-(3,5-dimethyl-1H-pyrazol-1-yl)-6-methyl-pyrimidin-4-yl]-amine(CyPPA),and CHF+apamin groups.We measured cardiac function,hemodynamic parameters,anatomic indicators,and sympathetic drive indicators(n=18).Western blot was used to examine the protein levels of mi-crotubule-associated protein 1 light chain 3-II(LC3-II)/LC3-I,beclin-1,P62,CK2α,SK2,and phosphorylated CaM.The number of SK2-positive neurons was measured using immunofluorescence staining.The NG108 cells were randomly divided into 6 groups:DMSO,aCSF,RAPA,3-MA,RAPA+DRB,and RAPA+CMDZ groups.Radioisotope 32P-ATP pro-tein kinase activity assays were used to detect CK2 activity in cultured NG108 cells.We used Western blot to examine the protein levels of CK2α,SK2,and phosphorylated CaM.RESULTS:Compared with CHF rats treated with vehicle,CHF rats treated with RAPA or apamin exhibited increased sympathetic drive indicators,but decreased left ventricular ejection fraction and fractional shortening(P<0.01).However,CHF symptoms,including sympathoexcitation,were attenuated by 3-MA,DRB,CMDZ or CyPPA infusion into the PVN(P<0.01).In CHF rats,RAPA infusion into the PVN induced CK2 activity,up-regulated LC3-II/LC3-I,beclin-1,CK2α,and phosphorylated CaM levels,but down-regulated P62 and SK2 expression,as well as the number of SK2-positive neurons(P<0.05 or P<0.01).In CHF rats,infusion of 3-MA or DRB into the PVN decreased CK2 activity,and down-regulated phosphorylated CaM level(P<0.01).Infusion of 3-MA,DRB or CMDZ into the PVN up-regulated SK2 expression and the number of SK2-positive neurons(P<0.01).In cultured NG108 cells,RAPA induced CK2 activation and up-regulated the expression of CK2α and the phosphorylation of CaM,but down-regulated SK2 expression(P<0.01).Treatment with RAPA increased the level of phosphorylated CaM and down-regulated SK2 expression in cultured NG108 cells(P<0.01),which was inhibited by DRB and CMDZ(P<0.05 or P<0.01).CONCLUSION:In rats with CHF,the CK2/CaM/SK2 signaling pathway in the PVN contributes to autophagy-induced sympathoexcitation.

Objective:To investigate the pathogenetic characteristics of clinical isolates of Streptococcus suis in Henan Province from 2020 to 2023. Methods:Eight clinical isolates of S. suis in Henan Province from 2020 to 2023 were identified using matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) and real-time fluorescence polymerase chain reaction (PCR). Serotype and virulence genes were detected by the serum agglutination test and PCR, and antibiotic susceptibility was evaluated using the microbroth dilution method. Multilocus sequence typing (MLST), minimum core genome (MCG), identification of antibiotic resistance genes, and core genome single nucleotide polymorphism (cgSNP) analysis were conducted using whole genome sequencing. Results:The results showed that eight S. suis strains isolated from humans were mainly serotype 2 (75.0%), while the rest were serotype 14 (25.0%). ST353 (62.5%) was the predominant genotype, followed by ST1 (25.0%) and ST7 (12.5%). All isolates belonged to the MCG1 group. The virulence genotypes of these isolates were primarily mrp(NA2)/ sly+/ ef+/ gapdh+(75.0%), while the remaining were mrp(EU)/ sly+/ ef+/ gapdh+(25.0%). These isolates carried tetracycline, macrolide, lincosamide and aminoglycoside resistance genes, and their resistance rates to tetracycline, erythromycin and clindamycin were 100.0%, 87.5% and 87.5%, respectively, and 62.5% strains were intermediate-resistant to penicillin. The cgSNP analysis indicated that these isolates were closer to the isolates from Guangdong, Zhejiang and Guangxi Provinces, with five ST353 strains and one ST7 strain belonging to Clade Ⅰ, and two ST1 strains belonging to Clade Ⅱ. Conclusion:The human isolates of S. suis in Henan Province are mainly ST353, harboring multiple virulence and antibiotic resistance genes.
