Neonatal diabetes mellitus （NDM） is a rare monogenic disorder primarily caused by insufficient insulin secretion resulting from mutations in the KCNJ11 and ABCC8 genes. Sulfonylureas， represented by glibenclamide， have become the standard therapy for this type of NDM by precisely closing the mutated ATP-sensitive potassium channels in pancreatic β cells， thereby restoring insulin secretion. Clinical studies confirm that sulfonylureas enable over 90% of patients to successfully transition from insulin to oral treatment， achieving long-term stable glycemic control and improving neurological outcomes to a certain extent. In terms of safety， severe hypoglycemia induced by sulfonylureas is relatively rare and gastrointestinal reactions are mild； moreover， sulfonylureas show good long-term tolerability， and have no adverse effects on child growth and development. In the future， by further refining the full-chain management pathway of “rapid genetic diagnosis-early intervention-specialized dosage forms-long-term follow-up”， the clinical application of sulfonylureas is expected to provide NDM patients with an optimized treatment regimen and maximize their health benefits.

Definitive chemoradiotherapy (dCRT) has become a cornerstone in the treatment of locally advanced esophageal cancer; however, local control remains suboptimal, and persistent lesions or locoregional recurrences after treatment are not uncommon. For patients without distant metastases but with local failure, whether surgical intervention can still offer curative potential remains a major clinical dilemma. Salvage esophagectomy (SE) offers potential long-term survival for selected patients, but this procedure is performed in the context of severe fibrosis, impaired local blood supply, and obscured anatomical planes following chemoradiotherapy, resulting in significantly higher perioperative risk compared to primary esophagectomy. Consequently, controversies exist regarding patient selection, preoperative restaging, choice of surgical approach, extent of lymphadenectomy, gastrointestinal reconstruction, and perioperative management. In recent years, with the refinement of restaging modalities such as PET/CT, the accumulation of experience in high-volume centers, and emerging evidence from clinical studies, the clinical role of SE has gradually shifted from a "high-risk salvage measure" to a "selective curative strategy aimed at achieving long-term survival in carefully selected patients". Nevertheless, standardized guidelines for patient selection, technical approaches, and perioperative management are still lacking. Based on current evidence and clinical experience, experts organized by the Integrated Esophageal Cancer Committee of Chinese Anti-Cancer Association systematically reviewed key issues regarding SE, including its definition, indications, preoperative evaluation, choice of surgical approach, lymphadenectomy, gastrointestinal reconstruction, and perioperative management, and formulated a Chinese expert consensus. This consensus aims to provide guidance for standardized assessment, appropriate referral, individualized surgical decision-making, and optimized perioperative management of patients with locoregional failure after dCRT. Ultimately, this will increase the likelihood of R0 resection, reduce the risk of severe complications, and promote the safer, more judicious, and standardized implementation of SE in high-risk scenarios.

Objective To explore the potential categories of frailty development trajectories in patients undergoing cardiac surgery from pre-operation to 6 months post-operation,and analyze the influencing factors.Methods By a longitudinal study design,patients undergoing elective heart valve replacement surgery or coronary artery bypass grafting in a tertiary general hospital in Zunyi City from August 2022 to June 2023 were selected by the convenience sampling method.Tilburg frailty scale was used to investigate the frailty level of cardiac surgery patients 1 day before surgery(T0),1 month(T1),3 months(T2)and 6 months after surgery(T3).The growth mixture model was used to identify the trajectory categories,and the influencing factors of different frailty trajectories were analyzed by binary Logistic regression.Results 261 patients were enrolled at T0,with 22,9,and 3 patients lost at T1 to T3,and 227 patients were finally included in the analysis.There were 2 types of trajectories being identified as the low frailty decline group and the high frailty maintenance group.Age,use of sedative and analgesic drugs,pace,and depression were the factors influencing the frailty in cardiac surgery patients(P＜0.05).Conclusion There are 2 kinds of frailty development trajectories in patients undergoing cardiac surgery.Medical staff should fonnulate precise interventions and nursing measures according to the factors influencing frailty,so as to improve frailty degree and quality of life of patients undergoing cardiac surgery.

Background: and Purpose Limited evidence exists on the effectiveness of endovascular treatment (EVT) for acute posterior circulation tandem lesion (PCTL). This study aimed to explore the role of extracranial vertebral artery (VA) stenting in patients with PCTL stroke undergoing EVT. Methods: Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery. Results: A combined dataset of 1,320 patients with posterior circulation artery occlusion, including 263 (19.9%) with tandem lesions, of whom 217 (median age, 65 years; 82.9% male) met the inclusion criteria for the analysis. The stenting group had 84 (38.7%) patients, while the non-stenting group had 133 (61.3%). After adjustment for the potential confounders, extracranial VA stenting was associated with favorable shifts in mRS scores at both 90 days (adjusted common odds ratio [OR], 2.30; 95% confidence interval [CI], 1.23–4.28; P<0.01) and 1 year (adjusted OR [aOR], 2.04; 95% CI [1.05–3.97]; P=0.04), along with lower rate of mortality at both 90 days (aOR, 0.45; 95% CI [0.21–0.93]; P=0.01) and 1 year (aOR, 0.36; 95% CI [0.16–0.79]; P=0.01), with no significant difference in sICH incidence (aOR, 0.35; 95% CI [0.06–1.98]; P=0.24). Conclusion Extracranial VA stenting during EVT may improve functional outcomes and reduce mortality in patients with PCTL strokes.

Objective To investigate the diversity and composition of gut fungi microbiota in patients with polycystic kidney disease(PKD)and its correlation with clinical indicators.Methods A total of 44 PKD patients,44 patients with non-polycystic chronic kidney disease(NPCKD)and 22 healthy controls(HC)admitted to our hospital from February 2023 to February 2024 were recruited.ITS1 DNA sequencing was applied to analyze the gut fungal composition.Bioinformatics analysis was used to compare the diversity and structural differences of fungi among the 3 groups.Pearson correlation analysis was performed to analyze the relationship between gut fungi and clinical indicators.Results There were no significant differences in baseline characteristics(gender,age,body mass index,etc.)among the 3 groups,but statistical differences were seen in terms of serum indicators(such as serum creatinine,blood urea nitrogen,uric acid,estimated glomerular filtration rate,etc.)(P<0.01).Alpha diversity analysis showed no significant difference was seen between the PKD and HC groups,but the PKD group had significant differences to the NPCKD group(P<0.01).Beta diversity analysis revealed significant differences among the 3 groups and in pairwise comparisons(P=0.001).Fungi composition analysis found that the abundance of Candida was significantly higher in the PKD group than the other 2 groups(P<0.01),while the abundances of Aspergillus and Cladosporium were significantly lower in the PKD group than the HC group(P<0.05).Linear discriminant analysis(LEFSe)indicated that Candida was significantly enriched,while Aspergillus and Cladosporium were significantly reduced in the PKD group.Correlation analysis revealed that the abundance of Cladosporium was negatively correlated with cyst diameter and immunoglobulin light chain Kappa/Lambda ratio in the PKD group(P<0.05),while the abundance of Candida was positively correlated with liver/kidney cyst diameter(P<0.01).Conclusion PKD patients exhibit characteristic changes in gut fungi diversity and composition.The abundances of Cladosporium and Candida are closely associated with clinical indicators of PKD patients.

Due to advances in treatment methods, the survival rate and quality of life of cancer patients have been improved. Radiation-induced vascular injury (RIVI) is a common adverse reaction following radiotherapy, mainly manifested as capillary injury and atherosclerosis in the irradiated area. Radiotherapy induces RIVI in the cerebral vessels, carotid arteries, coronary arteries, and large arteries through mechanisms such as endothelial cell injury and senescence, oxidative stress and inflammatory responses, angiogenesis, and vascular remodeling. In this review research progress in the pathological features, pathophysiological mechanisms, clinical manifestations, prevention and treatment strategies of RIVI was summarized, aiming to provide insights for future research on RIVI.

Radiation-induced rectal injury (RRI) refers to inflammatory intestinal complications of patients with pelvic cavity, abdominal cavity and retroperitoneal tumor during or after radiotherapy, presenting symptoms such as diarrhea, abdominal pain, anal distension, bloody stool, etc. In severe cases, rectovaginal fistula, intestinal obstruction, canceration can occur, adversely affecting the quality of life of patients. The clinical factors of RRI involve total radiotherapy dose, tumor volume, radiotherapy mode and patient-related risk factors. The diagnosis mainly depends on imaging examinations (such as CT, MRI and ultrasound), endoscopy and laboratory examination. The mechanism of RRI is related to intestinal epithelial cell destruction, stem cell injury, microvascular changes and microbial flora imbalance. At present, there is no gold standard for RRI treatment, and the main measures include surgical treatment, internal medicine treatment, hyperbaric oxygen therapy and fecal microbiota transplantation, etc. In this article, the latest progress in the pathogenesis, diagnosis and treatment of RRI was reviewed.

Radiation-induced esophageal injury (RIEI) is a frequent complication following radiotherapy for thoracic and head-neck malignancies, which may lead to severe sequelae including esophageal stricture and perforation, adversely affecting patients' quality of life and therapeutic outcomes. With advancements in radiotherapy techniques — particularly the adoption of unconventional fractionation regimens, concurrent chemoradiotherapy, and combined molecular targeted / immunotherapy — the incidence of RIEI has been increasing. In this review, recent advances in understanding the pathogenesis, clinical manifestations, risk factors, and management strategies for RIEI were comprehensively summarized. Current therapeutic approaches have evolved beyond conventional anti-inflammatory and nutritional support to include novel interventions such as targeted therapy, free radical scavengers, and microbiota modulation, etc. Future research should prioritize the development of optimized, individualized prevention and treatment protocols to mitigate RIEI risk and improve patient prognosis.
