Objective To investigate the efficacy of preoperative nebulized indocyanine green (ICG)-assisted thoracoscopic anatomical lesion resection (TALR) in treating pediatric congenital pulmonary airway malformation (CPAM). Methods A retrospective analysis was conducted on clinical data of 45 children with CPAM who underwent thoracoscopic surgery at the Third Affiliated Hospital of Zhengzhou University between June 2023 and March 2025. The patients were divided into an ICG group (preoperative nebulized ICG 0.5 mg/kg+TALR) and a non-ICG group (TALR under white light), with perioperative and postoperative recovery parameters compared between groups. Results A total of 45 children [22 males, 23 females; median age 7.4 (1.1-75.0) months] were enrolled. The ICG group (n=22) and non-ICG group (n=23) both achieved uneventful recoveries. Compared to the non-ICG group, the ICG group demonstrated significantly shorter surgical duration [91.3 (38.0-144.0) min vs. 100.0 (50.0-175.0) min, P=0.032], reduced intraoperative blood loss [3.0 (2.0-10.0) mL vs. 5.0 (1.0-10.0) mL, P=0.049], shorter postoperative drainage duration [2.7 (1.9-3.9) d vs. 3.4 (1.8-19.9) d, P=0.003], and shortened hospital stay [4.6 (2.9-9.8) d vs. 5.0 (3.9-21.5) d, P=0.013]. Residual lesions occurred in 2 patients from the non-ICG group but none in the ICG group. Intragroup comparisons revealed significant improvements in ratio of time to peak tidal expiratory flow to expiratory time, ratio of volume to peak tidal expiratory flow to expiratory volume, and tidal volume per kilogram after surgery in both groups (P<0.05), though intergroup differences showed no statistical significance (P>0.05). Conclusion Preoperative nebulized ICG administration facilitates lesion identification in CPAM, reduces technical difficulty of TALR, enhances therapeutic outcomes, and provides valuable assistance for performing TALR procedures.

ObjectiveTo investigate the safety and efficacy of transparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy （EHL）. MethodsA retrospective analysis was performed for the clinical data of 60 patients with large common bile duct stones who were admitted to Department of Gastroenterology， Jilin People’s Hospital， from May 1， 2023 to January 31， 2026， and according to the treatment method， the patients were divided into transparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group and peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group， with 30 patients in each group. The two groups were compared in terms of the rate of successful single-session stone fragmentation and removal， procedural time， duration of electrohydraulic lithotripsy， clinical success rate， and complications. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsCompared with the peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group， the transparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group had a significantly higher technical success rate （83.33% vs 60.00%， χ²=4.022， P=0.045） and significantly shorter procedural time ［46.00 （42.25 — 49.00） min vs 54.50 （42.00 — 65.00） min， Z=2.012， P=0.044］ and duration of electrohydraulic lithotripsy ［8.00 （6.25 — 11.75） min vs 13.50 （9.25 — 17.75） min， Z=2.749， P=0.006］. Both groups achieved a clinical success rate of 100%， with no significant difference in the incidence rate of complications （P>0.05）. ConclusionTransparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy has a high rate of successful single-session stone fragmentation and removal and a short procedural time， with good safety and efficacy， and therefore， it holds promise for clinical application.

ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography （ERCP） combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy， Jilin People’s Hospital， from May 2022 to June 2024， and related data were collected， including the success rate of surgery， the technical success rate of gallbladder polyp removal， the superselective method of cystic duct， the time of operation， the time of gallbladder polyp removal， and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%， and of all eight patients， three patients used guide wire to enter the gallbladder under direct view， while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes， and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2‍ ‍—‍ ‍8 mm， and pathological examination showed inflammatory polyps in three patients， adenomatous polyps in one patient， and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2‍ ‍—‍ ‍27 months after surgery， and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

Objective:To investigate the comorbidity rate of chronic diseases and prevalence of depressive symptoms among the middle-aged and elderly population,and explore the association between comorbidity with-chronic disease and depressive symptoms in middle-aged and older people.Methods:A cross-sectional study was conducted in Shandong Province.A total of 9 535 middle-aged and older people aged 45 years and over were recrui-ted.General information questionnaire,the chronic disease information questionnaire and Patient Health Question-naire were used for face-to-face interview to screen symptoms and collect information.Univariate analysis and mult-ivariate logistic regression analysis were employed to explore the association between comorbidity with chronic dis-ease and depressive symptoms.Results:The prevalence of depressive symptoms among middle-aged and older peo-ple was 8.7％,while among those with comorbid chronic diseases,the prevalence of depressive symptoms was 29.6％.Respectively,demonstrating an increasing trend with the number of chronic diseases(P＜0.001).Multiva-riate analysis revealed that comorbid chronic disease(OR=1.47,95％CI:1.22-1.78)were risk factors of depres-sive symptoms.Conclusion:Middle-aged and older people with multiple chronic conditions are more likely to be di-agnosed with depressive symptoms,and the detection rate of these symptoms increases with the number of comorbid chronic conditions.Therefore,it is recommended to strengthen mental health interventions for those with multiple chronic conditions.

Antibiotic adjuvants offer a promising strategy for restoring antibiotic sensitivity, expanding antibacterial spectra, and reducing required dosages. Previously, compound 15 was identified as a potential adjuvant for Polymyxin B (PB) against multidrug-resistant (MDR) Pseudomonas aeruginosa DK2; however, its clinical utility was hindered by high cytotoxicity, uncertain in vivo efficacy, and an unclear synergetic mechanism. To address these challenges, we synthesized and evaluated a series of novel benzamide derivatives, with A22 emerging as a particularly promising candidate. A22 demonstrated potent synergistic activity to PB, minimal cytotoxicity, improved water solubility, and broad-spectrum synergism of polymyxins against various clinically isolated MDR Gram-negative strains. In vivo studies using Caenorhabditis elegans and mouse models further confirmed the efficacy of A22. Moreover, A22 effectively suppressed the development of PB resistance in Pseudomonas aeruginosa DK2. Mechanistic investigations revealed that A22 enhances polymyxins activity by inducing reactive oxygen species production, reducing ATP levels, increasing NOX activity, and inhibiting biofilm formation, leading to bacterial death. These findings position A22 as a highly promising candidate for the development of polymyxin adjuvants, offering a robust approach to combating MDR Gram-negative bacterial infections.

Acute respiratory distress syndrome (ARDS) is a common respiratory emergency, but current clinical treatment remains at the level of symptomatic support and there is a lack of effective targeted treatment measures. Our previous study confirmed that inhalation of hydrogen gas can reduce the acute lung injury of ARDS, but the application of hydrogen has flammable and explosive safety concerns. Drinking hydrogen-rich liquid or inhaling hydrogen gas has been shown to play an important role in scavenging reactive oxygen species and maintaining mitochondrial quality control balance, thus improving ARDS in patients and animal models. Coral calcium hydrogenation (CCH) is a new solid molecular hydrogen carrier prepared from coral calcium (CC). Whether and how CCH affects acute lung injury in ARDS remains unstudied. In this study, we observed the therapeutic effect of CCH on lipopolysaccharide (LPS) induced acute lung injury in ARDS mice. The survival rate of mice treated with CCH and hydrogen inhalation was found to be comparable, demonstrating a significant improvement compared to the untreated ARDS model group. CCH treatment significantly reduced pulmonary hemorrhage and edema, and improved pulmonary function and local microcirculation in ARDS mice. CCH promoted mitochondrial peripheral division in the early course of ARDS by activating mitochondrial thioredoxin 2 (Trx2), improved lung mitochondrial dysfunction induced by LPS, and reduced oxidative stress damage. The results indicate that CCH is a highly efficient hydrogen-rich agent that can attenuate acute lung injury of ARDS by improving the mitochondrial function through Trx2 activation.

Pathological fractures after jaw cyst surgery are rare clinically but are a serious complication. Once a pathological fracture occurs, treatment time and economic costs increase, and doctors face difficulty in handling it. This article reports a case of a patient with mandibular pathological fractures after multiple odontogenic keratocyst surgery of the jaw. Mandibular lesions were located in the bilateral mandibular angles and had macrocystic changes. We adopted a conservative treatment plan, and the treatment effect was good. We also discussed and analyzed relevant literature to provide a reference for clinicians.

Atypical lipomatous tumor(ALT)is a rare soft tissue sarcoma originating from adipocytic tissue.The clinical manifestations,imaging findings,and pathological examinations of one patient with ALT in the lower extremity were reported to provide reference for the clinical diagnosis and treatment of this disease.The patient was a 64-year-old male who was admitted due to a mass in the left thigh with swelling and pain for 5 years.The physical examination results showed a subcutaneous mass was palpable on the medial side of the left thigh,soft in texture,demonstrating good mobility and positive tenderness.The magnetic resonance imaging(MRI)non-contrast scan showed a well-defined lesion with an intact capsule.The lesion presented high signal intensity on T1-weighted image(T1WI),similar to subcutaneous fat signal;on T2-weighted image(T2WI)-Ideal in-phase images,the lesion showed high signal,while water images showed low signal,with multiple high-signal foci inside.On T2WI fat-suppression sequence,a low-signal mass was observed with multiple patchy high signals inside.Three days after admission,the patient underwent lesion resection.Intraoperatively,the tumor was located within the fascia,between the medial quadriceps muscles,presenting as lipomatous tissue with an intact capsule,mildly adherent to surrounding tissue,and with partial muscle invasion.The mass and invaded muscle were completely excised.The postoperative pathological examination results revealed a gray-yellow nodule measuring 16.0 cm.× 10.0 cm×4.0 cm,with a smooth surface and intact capsule.The cut surface was gray-yellow,fatty-like,and soft in texture.Additional gray-yellow tissue fragments were found,with a total volume of 5.0 cm×4.0 cm×1.2 cm,exhibiting a gray-brown cut surface with moderate texture.Under microscope,the lesion consisted mainly of relatively mature adipose tissue.Enlarged and hyperchromatic nuclei were observed,with scattered mononuclear or multinuclear atypical stromal cells.Fibrous septa contained variable numbers of univacuolated or multivacuolated lipoblasts.The immunohistochemistry results showed positivity for cyclin-dependent kinase 4(CDK4)and murine double minute 2(MDM2).The fluorescence in situ hybridization(FISH)results demonstrated MDM2 gene amplification in tumor cells.The pathological diagnosis was ALT of the left lower extremity.At 6-month follow-up after operation,no tumor recurrence was observed.The preoperative MRI detection may provide effective evidence for the diagnosis of ALT,while postoperative pathological examination can confirm the diagnosis and help evaluate the prognosis of the patients.
