Objective:To explore the mediating role of dietary health beliefs in the relationship between family functioning and the frequency of sugar-containing food intake among adolescents with dental caries, in order to clarify the underlying mechanism through which dietary health beliefs influence caries-related dietary behaviors via family factors.Methods:Using convenience sampling method, we selected adolescents patients diagnosed with dental caries and their parents who visited the Affiliated Stomatological Hospital of Nanjing Medical University from July to September 2023 as the research subjects. Conducted a cross-sectional survey using a general information questionnaire, Family Functioning Scale, Adolescent Dietary Health Belief Scale, and Sugar-Sweetened Diet Intake Frequency Scale. Mediation analysis was conducted.Results:A total of 475 questionnaires were distributed, and 460 valid responses were obtained, yielding a valid response rate of 96.84%. Among the 460 adolescent patients, 306 were female and 154 were male, with a mean age of (13.42 ± 1.17) years old. The mother's age was (40.28 ± 4.24) years old, and the father's age was (42.12 ± 4.48) years old. The score for the frequency of sugar-containing food intake was 15.95 ± 5.34, the dietary health belief score was 75.57 ± 18.62, and the family functioning score was 174.24 ± 25.39. Family functioning was positively correlated with dietary health beliefs ( r = 0.428, P<0.05), and negatively correlated with the frequency of sugar-containing food intake ( r = -0.225, P<0.05). Dietary health beliefs were negatively correlated with the frequency of sugar-containing food intake ( r = -0.332, P<0.05). The mediating effect of dietary health beliefs on the relationship between family functioning and sugar-containing food intake frequency was -0.332, accounting for 43.92% of the total effect. Conclusions:Dietary health beliefs play a partial mediating role between family function and the frequency of sugary diet intake. It is suggested that family function construction should be strengthened to improve adolescents' health beliefs and reduce the incidence of dental caries.

Objective:To explore the effect of persuasion system-based health intervention in orthodontic patients treated with clear aligners.Methods:From January 2022 to December 2023, convenience sampling was used to select patients treated with clear aligners at the Department of Orthodontics in Affiliated Stomatological Hospital of Nanjing Medical University as participants. Patients admitted from January to December 2022 were included in the control group ( n=60), and those admitted from January to December 2023 were included in the observation group ( n=59). The control group received health guidance based on the theory of knowledge, attitude, and practice. Based on the control group, the observation group added health intervention with the assistance of a persuasion system. After one year of intervention, the oral care self-efficacy, enamel demineralization, periodontal health index (gingival index, plaque index, sulcus bleeding index, probing depth), and restart rate of both groups were evaluated. Results:After the intervention, the scores of the Self-efficacy Scale for Self-care in the observation group were higher than those in the control group, and the difference was statistically significant [ (71.03±1.97) vs. (57.82±2.58), P<0.01]. The enamel demineralization rate, periodontal health index (plaque index, gingival index, sulcus bleeding index, probing depth) score, and restart rate in observation group were all lower than those in control group ( P<0.05) . Conclusions:Persuasion system system-based health intervention can improve the oral care self-efficacy of orthodontic patients treated with clear aligners, alleviate oral health issues during clear aligners, and reduce the restart rate of clear aligner patients.

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.
