Objective:Eosinophilic esophagitis (EoE), an allergen/immune-mediated chronic disorder of the esophagus, is witnessing an incremental rise in its global incidence. However, data in China are very limited. This study aimed to clarify the characteristics of EoE in Chinese adults at our medical center.Methods:We collected information, including clinical characteristics and endoscopic findings, relative to all cases of adult patients who met the pathological diagnostic criteria for EoE at our institution from January 2019 to May 2024. Patients diagnosed with reflux esophagitis (RE) were matched in a 1∶1 ratio based on age and sex, and comparisons were made between the two groups.Results:The overall detection rate of EoE in our hospital was approximately 0.05%, with a trend increasing yearly. In total, 61 patients met the diagnostic criteria for EoE, of whom 42 (68.9%) were male. The median age was 53 years. The clinical manifestations of EoE patients were diverse, with common symptoms including dysphagia, acid reflux, and upper abdominal pain. Serological examination revealed that 23.1% (9/39) of patients had increased absolute eosinophil counts. Allergic diseases were observed in 73.8% (45/61) patients. Most patients exhibited typical mucosal changes in the esophagus during endoscopy, the median EREFS score was 3 points. The most commonly administered treatment included proton pump inhibitors, and 13 patients received steroid treatment. During a follow-up period, 42 patients (68.9%) exhibited clinical symptom improvement or pathological remission. In comparison to Western countries, patients with EoE in China typically presented with milder disease severity and a more favorable prognosis. No significant differences were observed between younger and older adult groups regarding clinical symptoms, the proportion of comorbid allergic diseases, medications, or the rate of improvement ( P for all>0.05). Additionally, patients with EoE more commonly presented with dysphagia (29.5% vs. 1.6%, χ2=15.96, P<0.001), comorbid allergic diseases (73.8% vs. 13.1%, χ2=45.67, P<0.001), increased eosinophil counts (23.1% vs. 3.3%, χ2=7.61, P<0.01), and a positive response to corticosteroids when compared to patients with RE. Conclusions:This study systematically determined the clinical characteristics of adult EoE patients in China. Compared to Western countries, patients from China typically presented with milder disease severity and a more favorable prognosis. No significant clinical manifestations or prognosis differences were observed between younger and older patients. EoE can be differentiated from RE based on symptoms, the presence of comorbid allergic diseases, and the degree of serum eosinophil infiltration. For patients suspected of EoE, endoscopic esophageal biopsy will facilitate early diagnosis.

Objective To explore the effect of psychological flexibility based psychotherapy model on cancer-related fatigue in lung cancer patients.Methods A total of 60 lung cancer patients admitted to Zhejiang Cancer Hospital from March 2022 to December 2023 were selected as research subjects.They were divided into control group(n=30)and study group(n=30)by using a random number table method.Control group received routine psychological intervention,while study group was treated with a psychological flexibility-based therapy model in addition to the routine intervention.The scores of anxiety self-rating scales,depression self-rating scales,perceived burden,coping strategies,and cancer-related fatigue were compared between two groups.Results After intervention,the self-assessment scale scores of anxiety and depression,self-perceived burden and cancer-related fatigue in both groups decreased,and the reduction was more significant in study group(P＜0.05).The coping style scores of both groups improved,and the improvement was more significant in study group(P＜0.05).Conclusion Intervention with a psychological flexibility-based psychotherapy model in lung cancer patients can reduce negative emotions,self-perception burden and cancer-related fatigue,and improve patients' coping style.

Objective To systematically evaluate the rehabilitation effect of immersive virtual reality technology for patients with peripheral vestibular dysfunction,and to provide theoretical basis and practical guidance for the design of efficient rehabilitation training programs.Methods PubMed,Embase,Cochrane Library,Web of Science,CINAHL,CNKI,Wanfang Database,VIP Database,and China Biomedical Literature Database were searched for randomized controlled trials on the intervention effect of immersive virtual reality technology in patients with peripheral vestibular dysfunction from inception to February 2025.RevMan5.4 software was used to perform meta-analysis of the literature that met the quality standards.Results A total of 10 papers with 491 patients with peripheral vestibular dysfunction were included.Meta-analysis showed that immersive virtual reality technology improved vertigo symptoms in patients with peripheral vestibular dysfunction compared with conventional vestibular rehabilitation care[SMD=-1.41,95％CI(-1.58,-0.70),P＜0.001],and subgroup analysis showed that the frequency of intervention was＜5 times/week[SMD=-1.31,95％CI=(-1.96,-0.66),P＜0.001],single intervention duration＜30 min[SMD=-1.45,95％CI=(-2.21,-0.70),P＜0.001],and intervention period≤7 weeks[SMD=-1.49,95％CI(-2.04,-0.94),P＜0.001]were more significant.Immersive virtual reality technology reduced the risk of falls[MD=4.66,95％CI(3.84,5.48),P＜0.001],and improved anxiety and depression[SMD=2.65,95％CI(1.98,3.33),P＜0.001].Conclusion Immer-sive virtual reality technology improves vertigo symptoms,reduces the risk of falls,and improves anxiety and depres-sion symptoms in patients with peripheral vestibular dysfunction,in which the intervention period of ≤7 weeks,＜5 training sessions per week,and each training session of＜30 min are better for improving vertigo symptoms in patients with peripheral vestibular dysfunction.

OBJECTIVE To evaluate the potential of nanopore sequencing technology for rapid diagnosis of Talaro-myces marneffei(TM)infection.METHODS Nine patients with TM infection admitted to the Fourth People's Hospital of Nanning from May 13,2022 to Aug.3,2023 were retrospectively analyzed.Rapid diagnosis was con-ducted by nanopore sequencing technology,and a comprehensive analysis of their clinical characteristics and treat-ment processes was performed.RESULTS The 9 patients included in the study had infections in various sites such as the lungs,buttocks,blood and cervical lymph nodes.Comorbidities included AIDS,secondary pulmonary tuberculosis,non-tuberculous mycobacterial disease and adult-onset immune deficiency.Patients generally exhibited elevated C-reactive protein levels and erythrocyte sedimentation rates,along with increased neutrophil counts.Some patients had abnormal lymphocyte counts and CD4+/CD8+ratios.Microbiological tests showed positive cultures in 3 cases,positive smears in 2 cases and positive targeted detection in 6 cases.Nanopore sequencing detected various pathogens in the 9 patients.The treatment results indicated that 8 patients improved after medication,with 6 patients having medication regimens adjusted based on nanopore sequencing results.CONCLUSION Nanopore sequencing technology has shown potentials in the auxiliary diagnosis of TM infection,providing timely etiological diagnostic evidence for clinical practice.

Objective:To analyze the patterns of change of brain function among civil pilots in prospective memory tasks by using task-state functional magnetic resonance imaging (fMRI) and a cue-based repetitive search task.Methods:A total of 85 subjects were enrolled, including 47 civil pilots (pilot group) and 38 ordinary workers (control group). The task-state fMRI data during the execution of the prospective memory task was analyzed using a general linear model to find out about the activation patterns of brain functions in the 2 groups in the 3 phases of encoding, maintenance, and retrieval of the prospective memory task. The differences in activation patterns between the 2 groups and correlations between regions of interest and the rate of accuracy, reaction time and flying hours were analyzed.Results:The repeated measurement analysis of variance showed that there were no interactions of reaction time or of the rate of accuracy between the task and grouping ( P>0.05), and that the difference in the main effect of grouping was significant ( F=5.67, 15.46, P=0.020, <0.001). The difference in the main effect of grouping on the rate of accuracy was significant ( F=5.42, P=0.022), and the rate of accuracy in the pilot group was higher than in the control group ( P=0.048). In the phase of encoding, the activation in the bilateral cerebellum, bilateral superior frontal gyrus, bilateral fusiform gyrus, and temporal lobe regions decreased in the pilot group compared with the control group ( t=2.68-4.13, all P<0.05), while the activation in the fusiform gyrus and the right parietal superior gyrus increased, and the differences were statistically significant ( t=3.28, 3.35, 3.02, P=0.038, 0.024, 0.042). During the phase of maintenance, the pilot group showed significantly reduced activation in the bilateral cerebellum, bilateral medial superior frontal gyrus, bilateral middle occipital gyri, and the right middle temporal gyrus compared with the control group ( t=2.24-3.36, P<0.05 or 0.01). In the retrieval phase, activation in the right peri-calcarine cortex, bilateral caudate nuclei, and bilateral precentral and postcentral gyri was enhanced in the pilot group compared with the control group ( t=2.57-3.35, all P<0.05), especially in the right middle frontal gyrus ( t=3.12, P=0.007). In the encoding phase, activation was increased in the left fusiform gyrus and right parietal superior gyrus of the pilot group, which was positively correlated with flying hours in the last 3 months ( r=0.347, 0.418, P=0.020, 0.005). Conclusions:Due to long-term flights, the way in which such regions as the frontal lobe, cerebellum, and default mode network are activated in civil pilots is likely to undergo some changes during prospective memory activities, which is why they have higher processing efficiency when performing prospective memory tasks.

Objective:To compare the efficacy and safety of extended-field versus reduced-field radiotherapy in upper tract urothelial carcinoma (UTUC) patients after radical operation.Methods:A retrospective analysis was conducted on the data of 210 UTUC patients who underwent full-length nephrectomy and received postoperative adjuvant radiotherapy in Peking University First Hospital from January 2013 to November 2023, and follow-up continued until June 2024. According to the target area of postoperative radiotherapy, patients were divided into the extended-field radiotherapy group (127 cases) and the reduced-field radiotherapy group (83 cases). The overall survival (OS), distant metastasis free survival (DMFS), local recurrence free survival (LRFS) and adverse reactions were compared. In the same period, 114 patients with recurrent abdominal and pelvic lymph nodes who did not receive adjuvant therapy after surgery for UTUC in our center were prospectively collected, and the coverage of the reduced-field target area was analyzed. Chi square test was used to compare the clinical characteristics, Kaplan-Meier method was used to analyze survival outcomes, log-rank test was used to compare the survival rate, and Cox multivariate regression analysis was performed on the influencing factors of survival.Results:The median follow-up was 24.5 (range: 3-74) months. There were no significant differences between the extended-field and reduced-field radiotherapy groups in terms of 2-year LRFS (93.3% vs. 98.1%, P=0.156), 2-year DMFS (84.8% vs. 91.2%, P=0.176), and 2-year OS (90.4% vs. 90.7%, P=0.707). The most common toxicities of adjuvant radiotherapy were nausea and leukopenia, with significantly higher grade 1-2 incidence in the extended-field group compared to the reduced-field group ( P<0.05). According to the analysis of patients with retroperitoneal lymph node recurrence after surgery, the reduced-field target designed according to the location of the primary tumor can cover more than 90% of the postoperative metastatic lymph node area Multivariate analysis revealed that variant histology ( HR=2.180,95% CI: 1.021-4.658, P=0.044) was an independent predictor of worse DMFS, while variant histology ( HR=3.825,95% CI: 1.514-9.662, P=0.005) and T 3-4 stage ( HR=4.452,95% CI: 1.025-19.339, P=0.046) were independent predictors of poorer OS. Conclusions:Compared with extended-field radiotherapy, reduced-field radiotherapy designed based on primary tumor location significantly reduced treatment-related toxicities without compromising postoperative therapeutic efficacy, and the reduced-field can cover more than 90% of local recurrent lesions.

In recent decades,the incidence of human papillomavirus(HPV)-associated oropharyngeal squamous cell carcinoma(OPSCC)has shown a marked increase.Significant changes have also occurred in the OPSCC diagnosis and treatment paradigm.Deter-mining HPV status prior to treatment is now essential,and radiotherapy/chemotherapy,immunotherapy,and minimally invasive surgical techniques have progressively emerged as key modalities for managing OPSCC.However,alongside these paradigm shifts,a comprehen-sive technical consensus guiding the entire diagnostic and therapeutic process for OPSCC patients is currently lacking.Given China's large population base and the rising incidence of OPSCC,an expert panel convened to develop a clinical technical consensus on OPSCC diagno-sis and management tailored to China's specific context.This consensus aims to further enhance and standardize understanding of OPSCC management techniques among relevant healthcare professionals.

OBJECTIVES: This cross-sectional study aims to explore the association between oral health status and cognitive function in Chinese elderly individuals. METHODS: The survey participants were composed of elderly people aged≥60 who were admitted to West China Hospital of Stomatology, Sichuan University from August 2022 to March 2024. They were divided into a cognitive impairment (CI) group and a healthy control (HC) group according to the Montreal Cognitive Assessment (MoCA) score. General information and oral health indicators of all elderly people were collected. Independent sample t-test and chi-square test were used for inter-group comparison, and multiple linear regression model was applied for multivariate analysis of MoCA scores. RESULTS: A total of 402 elderly people were included in the study, and the number of remaining teeth in the CI group was significantly lower than that in the HC group. The decayed, missing, filled teeth index, debris index-simplified, gingival index, probing depth (PD), and clinical attachment loss in the CI group were all significantly higher than those in the HC group. There was no difference in denture wearing between the two groups. The results of multiple linear regression showed that there was a correlation between the number of remaining teeth and PD and MoCA scores after correcting for confounding factors. CONCLUSIONS Elderly individuals with CI have more prominent oral health issues compared to those with normal cognitive function. There may be a bidirectional relationship between the number of remaining teeth, PD, and cognitive function in elderly people.
