Objective To compare the performance of 7 Chinese-developed GenAI models (DeepSeek, Wenxin Yiyan, Tongyi, Doubao, Kimi, Hunyuan, and iFLYTEK Spark) in responding to common diseases of the pediatric genitourinary system and to explore their potential applications.Methods A total of 80 questions covering basic disease information, diagnosis, treatment, and prognosis related to “hypospadias, hydronephrosis, and cryptorchidism” were developed as prompts.The models were tested under 3 modes:“quick thinking, ”“deep thinking, ” and “deep thinking + internet access.” The results were evaluated in a blinded review by two pediatric urologists.The responses were graded into 4 levels—A, B, C, and D—based on accuracy, completeness, and relevance.The proportions of responses rated as A and A+B were statistically analyzed and compared across the different models/modes.Results The “deep thinking” mode of DeepSeek demonstrated the best performance, with 88% of responses rated as A and 96% rated as A+B.DeepSeek (deep thinking + internet access), Doubao (quick thinking), Hunyuan (deep thinking), and Doubao (deep thinking + internet access) followed closely, also showing excellent response capabilities.Among the top 5 models/modes, significant differences were observed in the proportion of Alevel responses (P＜0.05), while differences in the proportion of A+B-level responses were not statistically significant (P＞0.05).Conclusion Certain Chinese-developed GenAI models, represented by DeepSeek (deep thinking), demonstrate significant application potential.However, they still cannot consistently provide recommendations rated at the A+B level (recommended grade or higher) with 100% accuracy.In clinical practice, both doctors and patients should view GenAI as an auxiliary tool for education and information acquisition rather than as a final decision-making authority.All information must be reviewed and confirmed by professional physicians.

Fungal infections are relatively common among patients with systemic lupus erythematosus (SLE), and patients may be infected simultaneously or sequentially with multiple fungal species. Physicians need to select appropriate antifungal agents and therapeutic regimens based on the type and severity of the infection. Herein, we report a young SLE patient who developed concurrent pulmonary infection with Pneumocystis jirovecii and Trichosporon coremiiforme. The patient presented with a variety of imaging manifestations, with specific features evolving as the disease progressed.

Objective To compare the clinical efficacy and safety of transarterial chemoembolization(TACE)plus apatinib(Apa)and camrelizumab(Cam)and TACE plus Apa in treating CNLC stage Ⅲ hepatocellular carcinoma(HCC).Methods A total of 54 patients in Affiliated Yancheng No.1 People's Hospital,School of Medicine,Nanjing University with CNLC stage Ⅲ HCC were enrolled in this study.The patients were divided into triple treatment group(n=25,receiving TACE plus Apa and Cam)and dual treatment group(n=29,receiving TACE plus Apa).The overall survival(OS)and progression-free survival(PFS)were compared between the two groups.Univariate analysis and multivariate analysis were used to determine the independent influencing factors for OS and PFS.The target immunotherapy-related adverse reactions(TRAE)were analyzed.Results The median OS and PFS in the triple treatment group were 23.2 months and 10.9 months respectively,which were higher than 15.2 months and 5.8 months respectively in the dual treatment group(both P＜0.001).Multivariate analysis indicated that the therapeutic regimen and the type of portal vein tumor thrombosis(PVTT)were the independent factors affecting OS,while only the therapeutic regimen was the independent factor affecting PFS.The incidence of≥grade Ⅲ TRAE in the triple treatment group and the dual treatment group was 20％(5/25)and 17.2％(5/29)respectively,the difference between the two groups was not statistically significant(P＞0.05).Conclusion For the treatment of patients with CNLC stage Ⅲ HCC,TACE plus Apa and Cam is superior to TACE plus Apa in OS and PFS,and the type of PVTT and the therapeutic regimen are the independent prognostic factors associated with patient's survival.

[Objective]To explore the academic characteristics and the current status of active inheritance of the acupuncture and moxibustion schools in northern Zhejiang.[Methods]Through literature search,data query,personnel interview and other ways,collect the relevant records of acupuncture and moxibustion in northern Zhejiang,sort out the representative schools and summarize their common academic characteristics.[Results]Upon reviewing the literature,it was discovered that the acupuncture and moxibustion schools in northern Zhejiang had a long and storied history,holding a significant position within the academic system of the"Xiushui medical school".Through historical medical research and interviews,it was summarized that the acupuncture and moxibustion in northern Zhejiang possessed five major academic characteristics:precise acupoint selection,diligent study of classics,skillful application of techniques,compassionate medical practice and emphasis on moxibustion therapy.However,the schools faced challenges such as slow transmission,traditional methods and limited dissemination scope during the process of inheritance.[Conclusion]The acupuncture and moxibustion schools in northern Zhejiang have demonstrated distinct academic characteristics and potential for intergenerational innovation in acupoint theory,manual skills and humanistic care.Their inheritance practices have deepened the academic connotations of the"Xiushui medical school".In the future,it is essential to enhance the current status of active inheritance through modern technology and communication methods to promote the widespread dissemination and sustainable development of the academic ideas of northern Zhejiang acupuncture and moxibustion.

Objective:To investigate the clinical characteristics and prognosis of follicular lymphoma (FL) patients with different primary sites using the Surveillance, Epidemiology, and End Results (SEER) database.Methods:Clinical data of 7167 patients with early-stage FL (stage I-II) from the SEER database between 2000 and 2015 were respectively analyzed. Primary sites were divided into intranodal and extranodal types. Intranodal primary sites included supradiaphragmatic lymph nodes (LN), subphrenic lymph nodes and Waldeyer's ring. Extranodal primary sites consisted of skin, gastrointestinal tract, duodenum, head and neck, other sites. Prognostic factors and overall survival (OS) in patients with different primary sites were analyzed. OS rate was evaluated using Kaplan-Meier method and survival difference between primary sites was compared with log-rank test. Inverse probability treatment weighting (IPTW) and multi-variable analysis were applied to adjust for confounding factors. Multivariate Cox regression analysis of influencing factors of OS was performed.Results:The median age was 63 years old, with the median follow-up time of 63 months. There was no difference in prognosis among the intranodal groups or between the intranodal and extranodal groups. The 10-year OS rates of the supradiaphragmatic lymph LN ( n=2146), subdiaphragmatic LN ( n=2811), and the Waldeyer's ring ( n=151) groups were 70.7%, 69.9% and 73.4%, respectively ( P=0.422 for infradiaphragmatic LN vs. supradiaphragmatic LN, P=1.000 for Waldeyer's ring vs. supradiaphragmatic LN), and 70.3% and 68.9% for intranodal ( n=5108) and extranodal ( n=2059), respectively. There was no significant difference in OS between the groups ( P=0.581) after IPTW adjustment. The most common primary sites in extranodal disease were skin, gastrointestinal tract, head and neck, and duodenum. The 10-year OS for skin, gastrointestinal tract, and cutaneous was 74.2%, 74.7%, and 87.3%, respectively, significantly higher than 55.6% for other sites (duodenum vs. others sites, gastrointestinal vs. others sites, skin vs. others sites: all P<0.001). Multivariate Cox regression analysis revealed that difference in OS was not significant among the intranodal groups or between the intranodal and extranodal groups. However, different extranodal primary site was an independent prognostic factor for OS. Conclusions:Early FL patients with supradiaphragmatic LN, subdiaphragmatic LN and Waldeyer's ring, and between the intranodal and extranodal primary sites obtain similar prognosis. However, early-stage FL patients with different extranodal primary sites have prognostic differences. The prognosis of primary skin, gastrointestinal tract and duodenum is significantly better than that of other extranodal primary sites.

Objective:To compare the clinical efficacy and adverse events of different postoperative radiotherapy strategies (adjuvant radiotherapy versus salvage radiotherapy) and different irradiation fields (prostate bed versus prostate bed + pelvic radiation) in patients after radical prostatectomy for prostate cancer.Methods:This retrospective analysis included clinical data from 115 patients with localized or locally advanced prostate cancer who received intensity-modulated radiotherapy (IMRT) after radical prostatectomy at Beijing Hospital between March 2014 and September 2023. Among them, 40 patients received adjuvant radiotherapy, and 75 received salvage radiotherapy. And 74 patients received irradiation to both the prostate bed and pelvic (prostate bed + pelvic radiation group), while 41 patients received irradiation to the prostate bed alone (prostate bed irradiation group). Comparison was made between the adjuvant radiotherapy group and salvage radiotherapy group, as well as between prostate bed + pelvic radiation group and prostate bed irradiation group, in terms of overall survival (OS), progression-free survival (PFS), locoregional recurrence-free survival (LRRFS), and the incidence of adverse events. Clinical characteristics were compared using the chi-square test. Survival rates were calculated using the Kaplan-Meier method and compared using the log-rank test. Prognostic factors affecting survival were analyzed using Cox multivariate regression.Results:The median follow-up duration was 73.1 months. The 5-year OS, PFS and LRRFS rates for the entire cohort were 96.4%, 86.4%, and 93.2%, respectively. A total of 59 patients (51.3%) experienced grade 1-2 acute radiotherapy-related adverse events, while 43 patients (37.4%) experienced grade 1-2 late radiotherapy-related adverse events. No grade ≥ 3 late adverse events were observed. There were no statistically significant differences in OS, PFS, or LRRFS between the adjuvant and salvage radiotherapy groups ( P = 0.807, 0.996, and 0.976, respectively), or in the incidence of grade 1-2 acute or late adverse events ( P > 0.05). The OS rate in the prostate bed + pelvic radiation group was significantly lower than that in the prostate bed irradiation group ( P = 0.036), while no significant differences were found in PFS or LRRFS ( P = 0.109 and 0.190, respectively), or in the incidence of grade 1-2 acute or late adverse events ( P > 0.05). Multivariable analysis showed no statistically significant differences in OS, PFS, or LRRFS between the adjuvant and salvage radiotherapy groups, or between the prostate bed and prostate bed + pelvic irradiation groups ( P = 0.756, 0.341, 0.605; 0.938, 0.987, 0.605, respectively). Conclusions:In the era of modern IMRT, both adjuvant and salvage radiotherapy, as well as prostate bed and prostate bed + pelvic irradiation, demonstrate similar efficacy and safety profiles after radical prostatectomy for prostate cancer. Treatment outcomes were favorable, and adverse events were minimal.
