Objective:To investigate the effect and underlying mechanism of sonodynamic therapy (SDT) on inflammation-related atrial fibrillation (AF) susceptibility.Methods:Lipopolysaccharide (LPS)-stimulated mouse and HL-1 mouse atrial myocyte models were used. (1) In vivo study: experimental groups included control, LPS, LPS+SDT, and SDT groups, with 20 mice in each group. Atrial fibrillation inducibility and duration were assessed by electrical stimulation. Western blot was used to analyze atrial expression of NOD-like receptor family pyrin domain-containing protein 3 (NLRP3), interleukin (IL)-1β, and IL-18. Immunohistochemistry was used to detect calcium voltage-gated channel subunit alpha1 C (CACNA1C) expression. (2) In vitro study: cell counting kit-8 (CCK-8) and Western blot were used to determine the optimal and safe LPS concentration. The safe incubation condition for the sonosensitizer sinoporphyrin sodium was determined by CCK-8 and fluorometry. An LPS-induced inflammatory model in HL-1 atrial myocytes was used, with experimental groups including control, LPS, LPS+SDT, LPS+sinoporphyrin sodium, and LPS+ultrasound groups. NLRP3 was overexpressed using plasmid transfection, with experimental groups including control, NLRP3 plasmid, negative control plasmid, and NLRP3 plasmid+SDT groups. SDT was applied to LPS-stimulated or NLRP3-overexpressing HL-1 cells. Quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot were used to measure mRNA and protein levels of NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), Cleaved Caspase-1, IL-1β, IL-18, and CACNA1C. The NLRP3 inhibitor MCC950 was used to validate the relationship of NLRP3 and CACNA1C. The experimental groups included control, LPS, LPS+MCC950, and MCC950 groups. Intracellular reactive oxygen species (ROS) levels were detected using the probe DCFH-DA, and the ROS scavenger N-acetyl-L-cysteine (NAC) was used to test if the effects of SDT was ROS-dependent.Results:(1) In vivo: The LPS+SDT group exhibited a lower incidence of atrial fibrillation induction and a shorter duration of atrial fibrillation compared to the LPS group(both P<0.05). Protein expression levels of NLRP3 and IL-1β were lower than those in the LPS group (all P<0.05), while the expression of CACNA1C subunit tended to increase relative to the LPS group ( P>0.05). (2) In vitro: The safe concentration of LPS for administration was ≤20 μg/ml, with an optimal pro-inflammatory concentration of 4 μg/ml. The safe concentration of sinoporphyrin sodium for administration was 0.4 μmol/L, with an optimal incubation time of 4 hours. Compared to the LPS group or NLRP3 plasmid group, the LPS+SDT group or NLRP3 plasmid+SDT group exhibited lower expression levels of NLRP3, ASC, Cleaved Caspase-1, IL-1β, and IL-18, and higher mRNA and protein levels of CACNA1C (all P<0.05). The LPS+MCC950 group had higher CACNA1C protein expression than the LPS group ( P<0.05). SDT increased intracellular ROS levels, and NAC blocked the regulatory effects of SDT on NLRP3 and CACNA1C. Conclusion:SDT reduces atrial fibrillation susceptibility in mice by inhibiting NLRP3 inflammasome activation in atrial cardiomyocytes, thereby upregulating the L-type calcium channel subunit CACNA1C.

Objective:To investigate the incidence of hypomineralized second primary molars (HSPM) and deciduous teeth caries in school-aged children of Kaifeng City, and to discuss the association between HSPM and deciduous teeth caries, providing scientific guidance for clinical prevention and treatment.Methods:A cross-sectional study was carried out on first-grade children aged 6-7 years in five primary schools chosen from the eastern, western, southern, northern, and central areas of Kaifeng City by cluster random sampling method. The European Academy of Pediatric Dentistry criteria was used for scoring HSPM. The International Caries Detection and Assessment System (ICDAS-Ⅱ) was used to evaluate caries status.Results:This cross-sectional study was with a sample of 913 children. The prevalence of HSPM was 8.76% (80/913), with 39 boys and 41 girls, the most common type of which was atypical caries [35.00% (28/80)]. Regarding the distribution of HSPM, the incidence in maxilla [6.13% (56/913)] showed no statistically significant difference with that in the mandible [5.70% (52/913)] (χ2=0.16, P=0.692). In terms of severity, 56 cases were severe and 24 cases were mild. The association between HSPM and deciduous teeth caries was analyzed. The results showed that 56 had caries on their second primary molars among the 80 HSPM children. Children with HSPM had an increased risk of second deciduous molar decay compared to non-HSPM children ( OR=1.94, 95 %CI: 1.18-3.19, P<0.05); meanwhile, the deciduous teeth of HSPM children were more prone to suffer caries than those of non-HSPM children ( OR=2.33, 95 %CI: 1.26-4.29, P<0.05). Conclusions:The HSPM prevalence in school-aged children of Kaifeng City was 8.76%. Child with HSPM was more likely to have deciduous teeth caries than non-HSPM child. Special attention should be paid to children with HSPM after the eruption of affected molars.

Objective To investigate the distribution and evolutionary patterns of traditional Chinese medicine(TCM)syndromes and syndrome elements during the malignant transformation from chronic pancreatitis(CP)to pancreatic intraepithelial neoplasia(Pan IN)and pancreatic ductal adenocarcinoma(PDAC).Methods A retrospective analysis was conducted on 710 patients(330 of CP,104 of Pan IN,276 of PDAC)diagnosed pathologically or clinically at Shanxi Institute of Traditional Chinese Medicine from January 2021 to June 2024.Data including demographics,laboratory results,and TCM diagnostic information were recorded using EpiData 3.1.Syndrome and syndrome-element patterns were determined via factor analysis and K-means clustering using SPSS 27.0.Results The study identifies seven TCM syndrome types in CP,Pan IN,and PDAC.Among CP patients,the syndrome distribution was primarily liver-gallbladder damp-heat syndrome(22.42％)and gastrointestinal excess-heat syndrome(20.91％),with excess syndromes accounting for a higher proportion(43.33％);the syndrome elements were mainly heat(51.52％)and dampness(35.15％),with the disease location in the pancreas,related to the liver,spleen,and stomach.In Pan IN patients,the syndrome distribution was mainly spleen deficiency with dampness obstruction(23.08％)and liver-gallbladder damp-heat syndrome(17.31％),with mixed deficiency-excess syndrome accounting for a higher proportion(30.00％);the syndrome elements were mainly heat(41.35％),dampness(40.38％),and qi deficiency(37.50％),with the disease location in the pancreas,related to the spleen and liver.In PDAC patients,the syndrome distribution was mainly spleen deficiency with dampness obstruction(29.71％)and qi-blood deficiency syndrome(20.29％),with deficiency syndromes accounting for a higher proportion(49.82％);the syndrome elements were mainly qi deficiency(50.00％)and dampness(36.23％),with the disease location in the pancreas,related to the spleen,kidney,and liver.Chi-square tests revealed significant differences in syndrome types(TCM syndromes:x2=100.419,P＜0.001;deficiency-excess syndromes:x2=73.722,P＜0.001),syndrome elements(x2=117.384,P＜0.001),and disease locations(x2=127.191,P＜0.001)across different stages of CP malignant transformation.During CP malignant progression,the proportion of excess syndromes gradually decreased(43.33％→12.32％),while deficiency syndromes increased(26.67％→49.82％).Excess syndrome elements(fire,heat,qi stagnation,blood stasis)decreased(53.48％→25.36％),whereas deficiency syndrome elements(qi deficiency,yin deficiency,yang deficiency,blood deficiency)increased(25.15％→49.64％).The disease location shifted from primarily the liver,spleen,and stomach in the inflammatory stage to the spleen and kidney in the cancerous stage.Conclusion The malignant transformation of CP basically involves the pancreas,is correlated early with liver and spleen-stomach and later with kidney,and exhibits a progression from excess to deficiency in the pattern of"deficiency interweaved with excess syndrome,transition from excess to deficiency,and progressive spleen deficiency".

Objective To compare and analyze the differences between customized models and commercial universal models in the segmentation of organs-at-risk in cervical cancer,and to investigate the feasibility of customized models.Methods A retrospective analysis was conducted on 270 cervical cancer patients.Senior clinicians manually delineated organs-at-risk,including the bladder,rectum,small intestine,pelvic bone marrow,femoral heads,and kidneys.The cases were randomly selected to develop customized models,with 202 cases allocated to the training set,38 cases to the test set,and 30 cases to the validation set.The universal and customized models were used for segmentation on the test set,and the automatic segmentation results obtained by the two models were compared with manual segmentation results to assess the performance of the customized model.Results Both customized model and universal model had comparable DSC values to manual segmentation,demonstrating satisfactory delineation outcomes(DSC values ranging from 0.7 to 0.9).However,in terms of deviation of centroid and 95％Hausdorff distance,the customized model surpassed the universal model.Conclusion Compared with the universal model,the customized model offers superior accuracy in delineating the structures of organs-at-risk in cervical cancer.As the customized model is optimized based on specific datasets,it provides precise support for clinical decision-making and holds promising applications in the treatment of cervical cancer.

Gestational diabetes mellitus(GDM) is one of the most common complications during pregnancy, with increasing incidence in recent years, significantly affecting the health of both mothers and their offspring across generations. The exact pathogenesis of GDM remains unclear; However, growing evidence suggests that dysbiosis of gut microbiota is involved in the development of GDM, and further influences the establishment of microbiota in the next generation through vertical transmission. This article summarizes the differences in gut microbiota between GDM mothers and their offspring compared to healthy controls. In addition, we also discuss the impact of gut microbiota dysbiosis on metabolic health in GDM offspring and potential mechanisms involved, aiming to provide a reference for targeting gut microbiota in the prevention and treatment of GDM and its complications in offspring.
