Objective:To explore the clinical characteristics of patients with brucellosis complicated with epididymo-orchitis (Brucellar epididymo-orchitis, BEO), so as to provide reference for clinical diagnosis and treatment of BEO.Methods:General and clinical data of 293 male patients with acute brucellosis admitted to the Beidahuang Industry Group General Hospital from January 2023 to December 2024 were retrospectively collected. They were divided into a BEO group (30 cases) and a non-BEO group (263 cases) based on the presence or absence of epididymo-orchitis. Epidemic characteristics, clinical manifestations and laboratory examination results were compared and analyzed.Results:Among 293 male patients with acute brucellosis, the incidence of BEO was 10.24% (30/293). Their age was mainly concentrated in 45 - < 60 years old (53.33%, 16/30), and occupation was mostly farmers (63.33%, 19/30). There were no statistically significant differences in the distribution of age, occupation, exposure history and onset season between the BEO group and the non-BEO group ( P > 0.05). The distribution of abdominal pain and urinary frequency/urgency/pain symptoms was compared, and the differences were statistically significant ( P < 0.05). White blood cell count (WBC), neutrophil count (NEUT), and C-reactive protein (CRP) levels in the BEO group were higher than those in the non-BEO group ( P < 0.05), while the levels of cytokines interleukin (IL)-6 and interferon-γ (IFN-γ) were lower than those in the non-BEO group ( P < 0.05). After 6 - 8 weeks of hospitalization, the levels of WBC, NEUT, CRP, albumin, alanine aminotransferase, aspartate aminotransferase, γ-glutamyl transpeptidase, alkaline phosphatase, α-hydroxybutyrate dehydrogenase, lactate dehydrogenase, IL-4, IL-6, IL-10, IL-17, tumor necrosis factor-α, and IFN-γ in patients of the BEO group were significantly different from before treatment ( P < 0.05). Twenty-eight patients were cured, 1 patient underwent orchiectomy, and 1 patient experienced recurrence. Conclusions:Middle-aged male patients with brucellosis are more prone to BEO. Clinical manifestations and laboratory tests have certain diagnostic value for BEO. Suspected BEO patients should be diagnosed and treated as early as possible to reduce the occurrence of adverse prognosis.

Objective:To learn about the clinical characteristics of patients with neurobrucellosis (NB) and provide references for clinical diagnosis and treatment of NB.Methods:The clinical data of 22 NB patients diagnosed and treated at Beidahuang Industry Group General Hospital from January 2018 to November 2024 and 178 healthy individuals undergoing physical examinations during the same period were retrospectively collected. The epidemiological characteristics, clinical manifestations, laboratory tests, treatment and prognosis of NB patients were analyzed.Results:Among the 22 NB patients, 12 were males (54.55%) and 10 were females (45.45%). The age was (51.77 ± 12.75) years old, ranging from 27 to 80 years old. Most of the patients were farmers (95.45%, 21/22), and 16 cases (72.73%) had contacted with cattle/sheep. The onset seasons were mainly in summer (40.91%, 9/22) and spring (31.82%, 7/22). Among all NB patients, there were 10 cases of encephalitis/meningoencephalitis, 9 cases of myelitis, and 3 cases of meningitis. The general symptoms were mainly fever (68.18%, 15/22), the neurological symptoms were mainly nausea and vomiting (36.36%, 8/22), and the physical signs were mainly muscle weakness (50.00%, 11/22) and pathological signs (45.45%, 10/22). The laboratory test results showed that the levels of hemoglobin, hematocrit, C-reactive protein, total protein, albumin, γ-glutamyl transpeptidase, α-hydroxybutyric acid dehydrogenase, lactate dehydrogenase, and glutathione reductase in NB patients were significantly different from those in healthy individuals ( P < 0.001). Brain magnetic resonance imaging revealed ischemic changes in 5 cases (22.73%), abnormal brain signals in 2 cases (9.09%), and demyelinating lesions in white matter in 1 case (4.55%). After treatment, 18 NB patients were followed up and showed good prognosis, with only 2 cases exhibiting varying degrees of sequelae (walking disorders or memory impairment). Conclusions:The clinical manifestations of NB patients are diverse. A comprehensive judgment should be made by combining epidemiological characteristics, clinical manifestations, laboratory tests and imaging examinations.

Objective:To analyze the clinical and endoscopic features of elderly patients with early gastric neuroendocrine neoplasms(g-NEN)to provide insights for clinical diagnosis and treatment.Methods:Seven cases of early-stage g-NEN in elderly patients admitted to Beijing Hospital from May 2020 to October 2024 were reported.Information including patient demographics, medical history, laboratory findings, endoscopic features, and pathological results was summarized an analyzed.Meanwhile, a literature review was conducted on g-NEN cases reported domestically and internationally from the establishment of databases to April 2025, with a comparative analysis of baseline characteristics, background mucosal conditions, and pathological diagnoses.Results:A total of 7 elderly patients with early g-NEN were included, including 3 males and 4 females, with an average age of 67 years at diagnosis.Endoscopic and pathological features: endoscopic lesions were mainly located on the greater curvature of the stomach, mostly slightly elevated, with 4/7(57.1%)being single lesions and the others accompanied by multiple polyps.The size of gastric neuroendocrine tumor(g-NET) lesions ranged from 1 mm to 19 mm, with a median Kyoto gastritis score of 3.In terms of pathological grading, there were 6 cases of G1 and 1 case of gastric neuroendocrine carcinoma(g-NEC). All 7 patients underwent endoscopic submucosal dissection(ESD). The follow-up period after surgery ranged from 3 months to 4 years, and no tumor was found at the vertical and horizontal margins of all lesions on pathology.A literature review of 32 reported cases showed that 40.6%(13/32)of cases exhibited background mucosal atrophy or intestinal metaplasia, with positive rates of chromogranin A(CgA) and synapsin(Syn)reaching 95.8%(23/24) and 100.0%(25/25), respectively.Notably, elderly patients with g-NEC demonstrated aggressive invasiveness, with a metastasis rate of 62.5%(5/8).Conclusions:Elderly patients with g-NEN exhibit high heterogeneity and significant differences in invasiveness, necessitating heightened clinical vigilance.Precise management should integrate background mucosal status, Kyoto gastritis score, pathological biomarkers, and imaging techniques.Blue laser imaging with magnifying endoscopy(BLI-ME)and endoscopic ultrasonography(EUS)can further analyze the characteristics of these tumors, and endoscopic submucosal dissection(ESD)remains the primary treatment modality for early-stage g-NEN.

In recent years, the association between gastrointestinal bleeding and frailty in the elderly has received increasing attention as clinical practice advances.Frailty has an important influence on adverse clinical outcomes in older patients with gastrointestinal bleeding.Choosing appropriate assessment tools for early identification of frailty, prevention and intervention of frailty is an important step of reducing the incidence of adverse outcomes in gastrointestinal bleeding.This article describes the relationship between gastrointestinal bleeding and frailty in older adults and personalized interventions.

Organ transplantation has emerged as a therapeutic modality for children with end-stage organ failure.With advancements in surgical techniques,organ preservation methods,and immunosuppressive thera-pies,both the success rate of transplantation and the long-term quality of life of recipients have continued to im-prove.Initially applied primarily in cardiothoracic transplantation,extracorporeal membrane oxygenation(ECMO)has gradually expanded its role in pediatric organ transplant recipients to include perioperative support for cardiopulmonary complications in abdominal organ transplants such as liver and kidney,as well as in the maintenance of deceased donors.With ongoing refinements in ECMO technology and equipment,its sig-nificance in supporting children with end-stage organ failure has become increasingly prominent,offering re-newed hope and survival for a growing number of pediatric patients with organ failure.

Objective:To analyze the differences in endoscopic and pathological features in autoimmune gastritis (AIG) patients with and without Helicobacter pylori ( HP) infection, and to explore the effects of HP on the clinical manifestations and disease development in AIG patients. Methods:From January 2022 to April 2024, 174 AIG patients who visited Beijing Hospital and met the 2022 AIG diagnostic criteria established by Japanese Gastroenterological Endoscopy Society were enrolled and divided into the HP-infected group (including current and previous infection, 77 cases) and the HP-unifected group (97 cases). The general clinical data, laboratory examinations endoscopic findings, and pathological characteristics of the two groups were analyzed. Independent sample t-test and chi-square test were used for statistical analyses. Results:The vitamin B 12 level of HP-infected group was higher than that of HP-unifected group ((573.81±460.77) ng/L vs. (411.86±335.00) ng/L), and the difference was statistically significant ( t=-2.57, P=0.011). The average red blood cell volume of HP-infected group was lower than that of HP-unifected group ((87.30±8.86) fL vs. (98.50±49.82) fL), and the difference was statistically significant ( t=2.16, P=0.033). The proportion of intestinal metaplasia in gastric fundus in HP-infected group was lower than that in HP-unifected group (50.6% (39/77) vs. 73.2% (71/97)), and the difference was statistically significant ( χ2=9.38, P=0.002). Conclusion:HP infection in AIG patients may delay the malabsorption of vitamin B 12 and the occurrence of intestinal metaplasia in gastric fundus.
