Objective:
To assess the effect of 12-year-old children s pit and fissure sealants on the health of first permanent molars, so as to provide evidence for optimizing caries prevention strategies among children.
Methods:
In March 2025, a cluster random sampling method was used to conduct oral examinations on 965 students aged 12 from Chengdu s 2021 Comprehensive Intervention Program for Pediatric Oral Diseases. Data from the Comprehensive Intervention System for Children s Oral Diseases were referenced. Participants were divided into a sealed group ( n =755) and an unsealed group ( n =210) based on whether they had received sealants on their first permanent molars. Chi square test or analysis of variance were used to compare indicators such as caries incidence, new caries detection rate, and new caries mean (DMFT increment) between the two groups
Results:
The sealed group showed significantly lower caries incidence, new caries detection rate, and new caries mean (33.38%, 17.65%, 0.59±1.00) compared to the unsealed group (43.81%, 24.70%, 0.87±1.22)( χ 2/F =7.79, 18.26, 9.55, all P <0.05). However, no significant difference was found in the filled teeth ratio between the two groups (20.38% , 20.16%; χ 2=0.01, P =0.94). In girls, the sealed group exhibited significantly lower caries incidence, new caries detection rate, and new caries mean (36.78%, 20.99%, 0.69± 1.10 ) than the unsealed group (57.55%, 33.52%, 1.15±1.29) ( χ 2/F =14.42, 23.76, 10.92, all P <0.05), whereas no significant differences were observed between boys in the sealed (30.47%, 14.85%, 0.50±0.89) and unsealed groups (29.81%, 16.18%, 0.59± 1.08) ( χ 2/F =0.02, 0.41, 0.74, all P >0.05). Boys had significantly lower new caries detection rates and new caries means than girls in both groups ( χ 2/F =16.20, 6.94; 29.93, 11.84, all P <0.05). In urban areas, the sealed group had lower new caries detection rates and new caries means (19.37%, 0.68±1.04) than the unsealed group (24.66%, 0.90±1.20) ( χ 2/F =6.86, 3.94, both P <0.05). In suburban areas, all indicators for the sealed group (24.71%, 13.77%, 0.42±0.87) were significantly lower than those for the unsealed group (38.81%, 24.77%, 0.82±1.28) ( χ 2/F =5.28, 15.36, 6.00, all P <0.05). Indicators from specialized dental institutions (11.25%, 4.81%, 0.16±0.56) were significantly lower than those from county level or above general hospitals (33.33%, 19.11%, 0.38±1.00) and primary healthcare institutions (37.59%, 19.24%, 0.67±1.05) ( χ 2/F =20.99, 34.31, 21.08 , all P <0.01).
Conclusions
The 12-year-old children s pit and fissure sealants effectively reduce the caries incidence in first permanent molars, particularly showing significant effectiveness in girls and suburban children. Intervention strategies should be optimized according to gender.

Cardiovascular diseases, a group of major non-infectious diseases, are characterized by high morbidity and mortality, significantly influencing patients' quality of life. Hence, it is imperative to discover a secure and efficacious treatment approach. As a form of programmed cell death, autophagy has been demonstrated to be associated with the pathogeneses of hypertension, diabetic cardiomyopathy, myocardial ischemia-reperfusion injury, heart failure, atherosclerosis, and other cardiovascular disorders. It serves as one of the potential targets for the clinical intervention in cardiovascular diseases by traditional Chinese medicine (TCM). Autophagy exerts dual regulatory effects on the occurrence and development of cardiovascular diseases, and its specific effect predominantly depends on the extent of autophagy and the pathological stage of diseases. Recent studies have confirmed that TCM can prevent and treat cardiovascular diseases by directly regulating autophagy or interacting with oxidative stress, inflammation, and apoptosis under the regulation of autophagy, exhibiting the unique advantages of multiple targets, multiple components, and mild adverse reactions. This article reviews the experimental research progress in the role of autophagy and the intervention by active components and compound prescriptions of TCM and Chinese patent medicines in common cardiovascular diseases (such as diabetic cardiomyopathy, myocardial ischemia-reperfusion injury, heart failure, and atherosclerosis) in recent years and summarizes the research shortcomings, providing a theoretical basis and strategies for the clinical treatment of cardiovascular diseases.

ObjectiveTo investigate the efficacy and underlying mechanisms of Gynostemma pentaphyllum alcohol extract in improving glucose and lipid metabolism disorders in db/db mice through transcriptomics and gut microbiota analysis. MethodsEighteen db/db mice were randomly assigned to the model(DM) group, metformin(MET) group, and G. pentaphyllum alcohol extract(GP) group, with six mice in each group, based on stratification of fasting blood glucose and body weight. An additional six db/m mice were selected as the normal control(NC) group. Mice in the NC and DM groups were administered deionized water (10 mL·kg-1) daily. The MET group received metformin (0.195 g·kg-1) by gavage. The GP group was treated with G. pentaphyllum alcohol extract (3.9 g·kg-1) by gavage for six weeks. Fasting blood glucose was measured every two weeks. After six weeks of intervention, serum levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine (CREA), and blood urea nitrogen (BUN) were assessed. Enzyme-linked immunosorbent assay (ELISA) was used to measure insulin (FINS), adiponectin (ADP), and tumor necrosis factor-α (TNF-α). Hematoxylin-eosin (HE) staining was used to observe liver histomorphology, periodic acid-Schiff (PAS) staining was employed to assess hepatic glycogen synthesis, and Oil Red O staining was used to detect hepatic lipid deposition. Liver transcriptomic data were used to identify differentially expressed genes in the liver and conduct enrichment analysis. Real-time PCR was employed to verify the expression levels of adiponectin gene (Adipoq), peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α), AMP-activated protein kinase (AMPK), peroxisome proliferator-activated receptor α (PPARα), glucokinase (GCK), forkhead box (Fox)O1, FoxO3, phosphoenolpyruvate carboxykinase (PEPCK), and glucose-6-phosphatase (G6PC). Metagenomic sequencing was conducted to analyze changes in gut microbiota composition. ResultsCompared with the NC group, the DM group exhibited significantly elevated fasting blood glucose (P<0.01), serum AST, ALT, TC, TG, LDL-C, and HDL-C (P<0.01). FINS, homeostatic model assessment for insulin resistance (HOMA-IR), and the inflammatory cytokine TNF-α were significantly increased (P<0.01), while ADP was significantly decreased (P<0.05). Histological analysis confirmed severe hepatic steatosis and excessive lipid accumulation in the DM group, along with markedly reduced glycogen synthesis. Compared with the DM group, the GP group showed significantly decreased fasting blood glucose (P<0.01), reduced serum TC, LDL-C, and HDL-C levels (P<0.05), significantly decreased serum TG and AST levels (P<0.01), significantly reduced FINS, HOMA-IR, and TNF-α levels (P<0.01), and significantly increased ADP (P<0.01). Hepatic steatosis and lipid deposition were significantly alleviated, while glycogen synthesis was markedly enhanced. Transcriptomic differential and enrichment analyses suggested that the mechanisms by which G. pentaphyllum alcohol extract improved hepatic glucose and lipid metabolism in db/db mice may involve regulation of the AMPK and FoxO signaling pathways. Real-time PCR results confirmed that expression of PGC-1α, PEPCK, G6PC, FoxO1, and FoxO3 was significantly downregulated following treatment with G. pentaphyllum alcohol extract (P<0.05, P<0.01), whereas mRNA expression of Adipoq, PPARα, GCK, and AMPK was significantly upregulated (P<0.05, P<0.01). Metagenomic analysis showed that the relative abundance of Lactobacillus, Alistipes, and Akkermansia species was higher in the GP group than in the DM group. ConclusionG. pentaphyllum alcohol extract may improve glucose and lipid metabolism disorders in db/db mice by regulating the hepatic AMPK/PPARα pathway to suppress lipid deposition and alleviate hepatic steatosis, by inhibiting gluconeogenesis through the AMPK/PGC-1α and FoxO pathways to lower fasting blood glucose, and by increasing the abundance of beneficial gut bacteria such as Lactobacillus, Alistipes, and Akkermansia to restore gut microbiota balance.

ObjectiveTo evaluate the therapeutic effects of modified Buwangsan on cognitive dysfunction in the rat model of type 2 diabetes mellitus with mild cognitive impairment (T2DM-MCI) and explore the underlying mechanism. MethodsThirty-six 5-week-old SPF-grade SD rats were randomly assigned into 6 groups: Normal (Con, fed with a normal diet), model (DM, fed with a high-sugar and high-fat diet), low-dose modified Buwangsan (L-BWS, 1.86 g·kg-1), medium-dose modified Buwangsan (M-BWS, 3.72 g·kg-1), high-dose modified Buwangsan (H-BWS,7.44 g·kg-1), and huperzine A (SSJJ, 0.018 mg·kg-1). The rats were treated by gavage once a day for 12 weeks. The body weight and blood glucose level were monitored dynamically. Morris water maze was employed to test the cognitive function of rats. Hematoxylin-eosin and Nissl staining were employed to observe the pathological changes of the hippocampus. The levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in the serum and hippocampus were assessed by enzyme-linked immunosorbent assay. Western blotting was employed to determine the expression levels of key autophagy-related proteins including microtubule-associated protein 1 light chain 3 (LC3), type Ⅲ phosphatidylinositol 3-kinase complex regulatory subunit (Beclin1), and phosphorylated UNC-51-like kinase (p-ULK) 1/2 in the hippocampus. Immunofluorescence staining was employed to observe the regulation of p-PI3K/PI3K, p-mTOR/mTOR, and p-Akt/Akt ratios. ResultsCompared with the DM group, the L-BWS, M-BWS, H-BWS, and SSJJ groups showed increases in body weight at the end of the experiment (P<0.05), and the M-BWS, H-BWS and SSJJ groups showed declines in fasting blood glucose level (P<0.05). In the water maze test, compared with the DM group, the M-BWS, H-BWS, and SSJJ groups presented shortened escape latency (P<0.001). The L-BWS, M-BWS, H-BWS, and SSJJ group showcased regularly arranged cells in the hippocampus and cortex, markedly increased number of neurons, and significantly recovered Nissl bodies. Compared with the DM group, the L-BWS, M-BWS, H-BWS, and SSJJ groups had reductions in the levels of IL-1β and IL-6 in the serum and hippocampus (P<0.05), increases in the LC3-II/LC3-I ratio and expression level of beclin1 in the hippocampus (P<0.05) and the p-ULK level (P<0.05). The p-PI3K/PI3K, p-Akt/Akt, and p-mTOR/mTOR ratios in the hippocampus decreased in the M-BWS, H-BWS, and SSJJ groups (P<0.01). ConclusionModified Buwangsan significantly ameliorates cognitive dysfunction and neurological damage in the rat model of T2DM through multiple mechanisms. It regulates metabolic disorders, lowers the blood glucose level, improves lipid metabolism, and alleviates oxidative stress. It promotes the protection and repair of neurons by inhibiting inflammatory responses and activating the autophagy pathway in the hippocampus. At the same time, modified Buwangsan relieves autophagy inhibition by regulating the PI3K/Akt/mTOR signaling pathway to alleviate the brain tissue injury.
