Objective: To evaluate and compare the accuracy of responses to pediatric preventive dentistry-related questions between the domestic large language model, ChatGLM-6B, and the international large language model, ChatGPT-3.5, in order to provide insights for further research and development of domestic language models in the field of oral medicine. Methods: A total of 100 common pediatric preventive dentistry questions of varying difficulty levels [basic (n = 35), intermediate (n = 35), and advanced (n = 30) ] were provided by pediatric preventive dentistry experts. Two doctors independently registered these questions with ChatGPT-3.5 and ChatGLM-6B and collected the answers. A cohort of 16 dentists assessed responses generated by ChatGLM-6B and ChatGPT-3.5 using a predefined 3-point Likert scale. The average score of the ratings from 16 doctors was taken as the answer score. If the answer score was higher than 2.8, it was accepted as a accurate answer; if the score was lower than 1.4, it was accepted as an inaccurate answer; if the score was between 1.4 and 2.8, it was accepted as a partially accurate answer. Comparative analysis was conducted on the accuracy rates and evaluation outcomes between the two groups. Consistency analysis of the ratings was conducted Results: The answer accuracy rates of ChatGPT-3.5 and ChatGLM-6B for 100 pediatric preventive dentistry questions were comparable: ChatGPT-3.5 demonstrated 68% accurate, 30% partially accurate, and 2% inaccurate responses, while ChatGLM-6B showed 67% accurate, 31% partially accurate, and 2% inaccurate responses, with no statistically significant differences (P>0.05). Both models exhibited equivalent accuracy across questions of varying difficulty levels (basic, intermediate, advanced), showing no statistical differences (P>0.05). The overall average scores for ChatGPT3.5 and ChatGLM-6B in answering all questions were both 2.65, with no statistically significant difference (P>0.05). For questions of different difficulty levels, ChatGPT3.5 had an average score of 2.66 for basic questions while ChatGLM-6B had an average score of 2.70. For intermediate questions, ChatGPT3.5 had an average score of 2.63 and ChatGLM-6B had an average score of 2.64. For advanced questions, ChatGPT3.5 had an average score of 2.68, and ChatGLM-6B had an average score of 2.61. No statistically significant differences were observed across any difficulty category (P>0.05). The consistency of the experts’ grading ranged from fair to moderate. Conclusion This study demonstrates the potential of both ChatGLM-6B and ChatGPT-3.5 in answering pediatric preventive dentistry questions. ChatGLM-6B performed similarly to ChatGPT-3.5 in this field, but the accuracy rates of both models fell short of expectations and are not suitable for clinical use. Future efforts should focus on improving the accuracy and consistency of large language models in providing medical information, as well as developing specialized medical models for the field of oral medicine.

Urinary tract infection (UTI) is one of the most common infectious diseases. It has the characteristics of high recurrence rate and prolonged course. At present, the problem of antibiotic resistance is becoming more and more serious, the incidence of adverse reactions is high, and the disadvantages of long-term administration appear, which brings severe challenges to the treatment of recurrent urinary tract infection. The prevention and treatment of UTI recurrence has become the focus of research. Recurrent urinary tract infection is related to the immune regulation mechanism of the body. Administration of immune regulation can provide new ideas for prevention and treatment. The vaccine based on immune regulation to prevent rUTI has made some progress. It can not only reduce the frequency of recurrences, but also decrease related symptoms. At the same time, the vaccine has good tolerance, high safety and good application prospect. This paper aims to summarize the progress of immune regulation and immune vaccines in vivo and clinical research.

Objective : To provide a reference for the diagnosis and treatment of mucoepidermoid carcinoma arising in Warthin’s tumor of the lip by investigating the diagnosis, treatment and prognosis of the disease. Methods : A case of mucoepidermoid carcinoma arising in Warthin’s tumor of lip was reported, including the clinical manifestation, treatment, pathological characteristics and prognosis. The related literature was also reviewed and analyzed. Results: A painless mass on the left lip lasting more than one month was found. Resection of the left lip was performed. Pathological examination showed that the tumor was a hybridoma composed of mucoepidermoid carcinoma and Warthin’s tumor. There was no recurrence or distant metastasis after 34 months. To date, this type of disease has been rarely reported. After thorough resection, the prognosis and survival rate are promising in most cases, with no recurrence or metastasis. Conclusion Mucoepidermoid carcinoma in Warthin’s tumor of the lip is rare. Clinical manifestations, imaging features and histological examination are useful when diagnosing the disease. Thorough resection will reduce the risk of disease recurrence.

Objective To investigate the effect of long non-coding RNA HOX transcript antisense RNA ( lncRNA HOTAIR ) on the cell proliferation, radiosensitivity and apoptosis of the rectal adenocarcinoma cell lines SW480 and HCT116 in vitro. Methods The expression levels of lncRNA HOTAIR in the rectal adenocarcinoma cell lines ( SW480 and HCT116 ) were assessed by real-time quantitative PCR (RT-qPCR).Silencing of HOTAIR by RNA interference was performed to explore its roles in cell proliferation,radiosensitivity and apoptosis. After treatment with irradiation at a gradient dose,the cell viability was measured and the rate of cell apoptosis was tested. Results Compared with the human rectal epithelial cell lines,the expression of lncRNA HOTAIR was significantly higher in the rectal adenocarcinoma cell lines. The colonic assay demonstrated that the sensitizing enhancement ratios ( SERs) were 1. 58 and 1. 33 for the cells transfected with HOTAIR siRNA in SW480 and HCT116 cell line compared with the control isRNA transfection group. In vitro silencing of lncRNA HOTAIR could enhance the apotosis rate and radiosensitivity of the rectal adenocarcinoma cell line SW480. Conclusion The expression level of lncRNA HOTAIR is correlated with the cellular radiosensitivity, which is probably a parameter for predicting the radiosensitivity of rectal adenocarcinoma cells. Radiotherapy combined with HOTAIR-siRNA can significantly inhibit the cell proliferation,induce cell apoptosis and enhance the radiosensitivity.
