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.

Objective To probe the relationship between the expression of TL1A and the level of IFN-γ secreted by T cells in the acute stage of Guillain-Barre syndrome (GBS). Methods ① Six-week female Bal b/c mice were immunized by purified recombinant human soluble TNF-like molecular 1A (rhsTL1A) protein. The polyclonal antibody against rhsTL1A was identified by immunofluorescence using human umbilical vein epithelial cells (HUVEC). ② To detect the biologic activity of rhsTL1A, the peripheral blood mononuclear cells (PBMC) from the healthy donors were separated by Ficoll gradient centrifugation and were seeded on 96-well plates with medium containing 2 μg/ml PHA (control group), 2 μg/ml PHA + 25 ng/ml rhsTL1 A, 2 μg/ml PHA + 100 ng/ml rhsTL1A and 2 μg/ml PHA + 400 ng/ml rhsTLlA respectively. T cell proliferation assay was carried out using ~3H-TdR. ③ IFN-γ productions in the sera of the children with GBS in the acute stage were detected by ELISA. ④ The ratio of CD_3~+ TL1A~+ T cells to CD_3~+ T cells in the peripheral blood of the children with GBS in acute stage was detected with flow, cytometry. ⑤PBMC from the children in acute GBS were separated and cultured in the environment adding 2 μg/ml PHA and 400 ng/ml rhsTL1A in vitro. Then, the IFN-γ in the supernatant was determined by ELISA kit after 72 hours. Results ① hTL1A A expressed by eukaryotic HUVECs was recognized by rhsTL1 A polyclonal antiserum. ② The result of T cell proliferation assay showed that SI of 25 ng/ml rhTL1A, 100 ng/ml rhTL1A A and 400 ng/ml rhTL1A group was increased compared with control group. The SI of 2 μg/ml PHA +400 ng/ml rhsTL1 A group was the highest (2. 65) among them. ③ IFN-γ productions in the sera of the children with GBS in the acute stage ((102. 25±22. 17) pg/ml) were increased significantly compared with healthy control ((28.75 ± 1.31) pg/ml, t = 3. 309, P < 0. 05). ④ The ratio of CD_3~+ TL1A~+ T cells to CD_3~+ T cells in the peripheral blood of the children with GBS in acute stage (18.22%± 1.83%) was enhanced significantly compared with healthy control (5. 17% ±0. 48%, t = 6. 884, P < 0. 01). ⑤ PBMC both in healthy control and the acute GBS secreted more IFN-γ markedly ((43.56± 4.41) pg/ml and (180.64 ± 38.39) pg/ml) after being incubated in 2 μg/ml PHA and 400 ng/ml rhsTL1A (t =4. 523 and 2. 600, P <0. 01 and 0. 05 respectively). Moreover, PBMC in acute GBS secreted more IFN-γ, than that of the healthy group markedly (t = 3. 545, P < 0. 05). Conclusions ① The mouse antiserum recognizing rhsTL1A is successfully obtained. ② In this study, 400 ng/ml rhsTL1A promotes the proliferation of T cells activated by 2 μg/ml PHA, indicating that rhsTL1A has biological activity. ③ The expression of hTL1A of activated T cells in the peripheral blood of the children with acute GBS is up-regulated. These TL1A proteins promote the secretion of IFN-γ through binding to their receptors DR_3.
