Metabolic associated fatty liver disease (MAFLD) is fundamentally driven by an imbalance in hepatic fatty-acid flux: the influx of fatty acids exceeds the liver’s capacity for disposal, resulting in excessive hepatic lipid accumulation, predominantly in the form of triglycerides (TGs). The occurrence and progression of MAFLD depend on disordered regulation across multiple metabolic steps, including fatty-acid uptake, de novo lipogenesis (DNL), fatty-acid oxidation (FAO), and very low-density lipoprotein (VLDL) export. Forkhead box protein O1 (FOXO1) is a key transcriptional regulator within the hepatic network coordinating glucose and lipid metabolism. Under metabolic stress and insulin resistance (IR), FOXO1 expression is frequently increased, whereas its inhibitory phosphorylation is reduced. These changes enhance FOXO1 nuclear localization and transcriptional activity, thereby reprogramming the expression of genes related to metabolism in the liver. Because hepatic lipid deposition is the central pathological feature of MAFLD, the functional status of FOXO1 directly influences hepatic lipid homeostasis. Growing evidence suggests that FOXO1 can exert bidirectional, environment-dependent effects on hepatic lipid accumulation; however, the molecular basis for this functional switch remains incompletely understood. This review systematically summarizes the biological functions and regulatory mechanisms of FOXO1 and its roles in hepatic lipid metabolism, with a particular focus on its crosstalk with insulin signaling. FOXO1 expression is shaped by RNA modifications and epigenetic regulation mediated by non-coding RNAs. Its transcriptional output is precisely governed by post-translational modifications—such as phosphorylation and acetylation—as well as by coordinated nucleocytoplasmic shuttling. Notably, these regulatory patterns vary markedly across nutritional states, degrees of insulin resistance, and stages of disease. In the fed state, insulin/IGF-1 signaling activates the PI3K-AKT pathway, promoting the inhibitory phosphorylation of FOXO1 and facilitating additional modifications, including acetylation, methylation, and ubiquitination. Together, these events drive FOXO1 export from the nucleus and dampen its transcriptional activity, suppressing gluconeogenesis and constraining lipogenic programs. Conversely, during fasting or when insulin signaling is weakened, FOXO1 inhibition is relieved. FOXO1 accumulates in the nucleus, binds to DNA, and regulates the transcription of downstream target genes. Mechanistically, FOXO1 can aggravate hepatic lipid accumulation by activating genes involved in TG synthesis while repressing FAO-related pathways, thereby favoring storage over oxidation. However, under specific conditions, FOXO1 may also alleviate the hepatic lipid burden by promoting TG hydrolysis and enhancing VLDL secretion, thereby reducing the net hepatic lipid load. In addition, lipotoxic signals mediated by ceramides and diacylglycerols (Cer/DAG) activate atypical protein kinase C (aPKC), further exacerbating the disruption of the AKT-FOXO1 axis. This vicious cycle ultimately produces a metabolic paradox in which increased hepatic glucose output coexists with persistent, insulin-independent lipogenesis, accelerating MAFLD progression. Importantly, FOXO1 regulation is not uniform: during early metabolic overload, insulin-mediated suppression may remain effective, whereas in advanced insulin resistance, the loss of AKT control permits sustained FOXO1 activity. Such stage-dependent dynamics may help explain why FOXO1 can either promote steatosis or, in certain contexts, support programs that facilitate lipid turnover. Accordingly, interventions should be liver-specific and tuned to the disease stage, aiming to curb maladaptive FOXO1 signaling while preserving its capacity to promote triglyceride hydrolysis and VLDL secretion when advantageous. Overall, this review offers an important perspective on MAFLD pathogenesis, emphasizing FOXO1 as a potential therapeutic target and providing a theoretical basis for developing liver-specific, disease-course-dependent precision interventions.

Necrotizing fasciitis (NF) is a rapidly progressive, life-threatening soft tissue infection that rarely involves the periorbital region. We report an unusual case of periorbital NF caused by methicillin-sensitive Staphylococcus aureus (MSSA) in a previously healthy 48-year-old woman, originating from a neglected, recurrent hordeolum—an otherwise benign eyelid condition. The infection resulted in an extensive fullthickness defect of the upper eyelid and adjacent temporal area, presenting major reconstructive challenges. Reconstruction was performed using a radial forearm free flap combined with a buccal mucosal graft to restore both anterior and posterior lamellae, achieving functional eyelid protection and improved visual acuity. This case highlights the potential for seemingly minor, recurrent eyelid infections to progress rapidly to devastating NF even in the absence of systemic symptoms or risk factors. Early recognition and multidisciplinary management were critical to preventing further morbidity. To our knowledge, MSSA has not previously been reported as a causative agent of periorbital NF, underscoring the need for clinical vigilance and timely intervention in common eyelid conditions to avoid catastrophic complications.

Objective To analyze the incidence rate and risk factors of atrial fibrillation (AF) in elderly patients with chronic obstructive pulmonary disease (COPD). Methods A total of 392 patients with COPD in the hospital were selected from December 2020 to December 2024. Patients' data (medical history, echocardiographic data, etc.) were recorded. The incidence rate of AF in patients was recorded and the patients were grouped according to whether or not they developed AF. The differences were compared between the two groups, and the risk factors of AF occurrence in elderly patients with COPD were analyzed. Results Among the 392 patients with COPD, 127 cases (32.40%) met the diagnostic criteria of AF. There were statistically significant differences in age, pulmonary infection, heart failure, diabetes, smoking history, disease duration, LAD, severe renal insufficiency and coronary heart disease between the AF group and the non-AF group (P<0.05). Multivariate logistic regression analysis suggested that age, pulmonary infection, heart failure, diabetes mellitus, smoking history, disease course, LAD, severe renal insufficiency and coronary heart disease were all risk factors for elderly patients with COPD (OR=1.129, 4.246, 3.955, 4.125, 2.038, 1.112, 1.102, 4.397, and 3.865, P<0.05). Conclusion The incidence rate of AF is high in elderly patients with COPD. Age, pulmonary infection, heart failure, diabetes mellitus, smoking history, course of disease, LAD, severe renal insufficiency, and coronary heart disease are all risk factors for AF.

Objective:To understand the clinical application of magnesium sulfate injection in inpatients of the obstetrical department, and analyze retrospectively its rationality and existing problems.Methods:The clinical data of obstetric inpatients who used magnesium sulfate injection in the hospital information system of our hospital from September 2022 to January 2023 were collected. Based on the drug instructions, guidelines for the diagnosis and treatment of hypertensive disorders in pregnancy, domestic and foreign guidelines, and literature reports, the rationality of magnesium sulfate injection in terms of obstetric medication indications, dosage and administration, and treatment course was evaluated.Results:A total of 303 obstetric patients were included in the use of magnesium sulfate injection, with an age of 32 (ranging from 18 to 44) years and a gestational age of 14 to 40 weeks. Among them, 33 cases were used for threatened abortion, 141 cases for threatened preterm birth, and 129 cases for the prevention of eclampsia attacks. Among the 303 patients, 134 cases (44.22%) had no indications for medication. Among them, 13 patients with threatened abortion were treated for fetal brain protection, and 20 patients with threatened abortion and 101 patients with threatened preterm birth were treated for preventing miscarriage by uterine contraction inhibition. There were 118 cases (38.94%) with inappropriate administration methods, mainly due to inappropriate usage and dosage, as well as overly long treatment courses. Of them, 26 cases (22.03%, 26/118) used for brain protectors of premature fetuses were not given loading doses, 15 (12.71%, 15/118) cases had a total medication duration of more than 48 hours, 76 cases (64.41%, 76/118) used for the prevention of eclampsia were not given loading dose, and 1 case (0.85%, 1/118) received rapid infusion time of the loading dose more than 30 minutes. Among the 303 patients, 3 patients presented nausea and vomiting, constipation, and skin flushing, respectively.Conclusions:Nearly half of the magnesium sulfate injection used in obstetrics department in our hospital has inappropriate indications and over one-third has non-standard usage, dosage, and treatment courses. Clinicians should comprehensively assess the patient′s condition and strictly follow recommended methods in the guidelines and drug instructions for standardized use.

Aim To investigate the possible mechanism of the myocardial protective effect of Danzhi Jiangtang capsules(DJC)on db/db mice based on NLRP3 in-flammasome-mediated pyroptosis.Methods The db/db mice were randomly divided into the model group,DJC low,medium,and high dose groups,and the met-formin group,and the db/m mice were taken as the blank group.The administration lasted for eightweeks.At the end of drug administration,blood glucose,blood lipids,cardiac enzymes and inflammatory factors were detected in each group of mice.HE and Masson stai-ning was performed to observe the morphology and fi-brosis of myocardial tissue.TUNEL staining was per-formed to detect apoptosis.RT-qPCR was performed to detect the mRNA expression of ANP,BNP and β-MHC,and Western blot was performed to detect the protein expression of NLRP3,ASC,caspase-1,cleaved-caspase-1,GSDMD and GSDMD-NT in myocardial tis-sue.Results DJC could alleviate myocardial patho-logical damage,reduce collagen deposition and apopto-sis,reduce the levels of blood glucose,blood lipid,myo-cardial enzyme and inflammatory factors in db/db mice.DJC could reduce the mRNA expressions of ANP,BNP and β-MHC,and the protein expressions of NLRP3,ASC,caspase-1,cleavedcaspase-1,GSDMD and GSDMD-NT in myocardial tissues.Conclusion DJC attenuates myocardial injury in db/db mice,prob-ably by inhibiting the activation of NLRP3 inflamma-somes,attenuating cardiomyocyte pyroptosis,and amel-iorating the inflammatory state.

Laparoscopic subtotal cholecystectomy (LSC) has been a safe and viable alternative to conversion to laparotomy in cases of severe cholecystitis. The objective of this study is to determine the utility of intraoperative choledochoscopy in LSC for the exploration of the gallbladder, cyst duct, and subsequent stone clearance of the cystic duct in cases of severe cholecystitis. A total of 72 patients diagnosed with severe cholecystitis received choledochoscopy-assisted laparoscopic subtotal cholecystectomy (CALSC). A choledochoscopy was performed to explore the gallbladder cavity and/or cystic duct, and to extract stones using a range of techniques. The clinical records, including the operative records and outcomes, were subjected to analysis. No LSC was converted to open surgery, and no bile duct or vascular injuries were sustained. All stones within the cystic duct were removed by a combination of techniques, including high-frequency needle knife electrotomy, basket, and electrohydraulic lithotripsy. A follow-up examination revealed the absence of residual bile duct stones, with the exception of one common bile duct stone, which was extracted via endoscopic retrograde cholangiopancreatography. In certain special cases, CALSC may prove to be an efficacious treatment for the management of severe cholecystitis. This technique allows for optimal comprehension of the situation within the gallbladder cavity and cystic duct, facilitating the removal of stones from the cystic duct and reducing the residue of the non-functional gallbladder remnant.

This study aimed to assess the utilization trends of pulmonary rehabilitation (PR) among lung cancer patients in Korea using the National Health Insurance Service (NHIS) database (2017 to 2021). PR was introduced and covered under the NHIS in 2016, primarily for chronic obstructive pulmonary disease, but recent evidence suggests its benefits for lung cancer patients. Data extraction was based on Korea Informative Classification of Diseases 8th revision codes C33 and C34, with PR prescriptions identified by codes MM440 and MM290.Descriptive statistical analysis was performed, and propensity score matching was used for comparison between PR and non-PR groups. Results showed a significant increase in PR utilization, with the number of patients receiving PR (MM440) rising from 1,002 in 2017 to 3,723 in 2021, indicating a 3.7-fold increase. However, the proportion of patients receiving PR remained low at 2.9% in 2021. Enhanced access to PR services and improved evaluation strategies are essential for optimizing patient outcomes.

Purpose: To investigate the genetic characteristics of patients with non-syndromic retinitis pigmentosa (RP) analyzed at a single institution. Methods: We conducted a retrospective analysis of 63 patients clinically diagnosed with non-syndromic RP who underwent genetic testing. The clinical features of patients exhibiting the most common mutations, EYS and USH2A, were further assessed through routine ophthalmic examinations. Results: Of the 63 patients, 22 (34.9%) exhibited significant mutations. Notably, EYS and USH2A mutations were each found in 5 patients (7.9%); RP1 mutations were found in 4 patients (6.3%). The average ages at diagnosis were 38.8 years for EYS mutations and 41.8 years for USH2A mutations. The average best-corrected visual acuities were logMAR 0.08 for EYS mutations and logMAR 0.51 for USH2A mutations. Both mutation types showed a decrease in the normal macular area in fundus photographs with increasing age. In USH2A mutations, optical coherence tomography revealed a more pronounced reduction in central macular thickness and central foveal ellipsoid length compared with EYS mutations. Visual field tests indicated a reduction within the central 10° in 40% of EYS mutations and 60% of USH2A mutations. Electroretinography showed non-detectable responses in 2 individuals with EYS mutations and 4 individuals with USH2A mutations (40% and 80%, respectively). Conclusions EYS and USH2A mutations represented 45% of the genetically identified cases; affected patients typically were diagnosed in their 40s. EYS mutations tended to preserve retinal function and central foveal structure better than USH2A mutations.

Objective:To explore the characteristics and influencing factors of risk perception related to additional injury during motor rehabilitation in stroke patients with hemiplegia, and to provide a foundation for the development of assessment tools and prevention strategies.Methods:A purposive sampling strategy combined with maximum variation sampling was employed to select 15 stroke patients with hemiplegia who were hospitalized in the Department of Neurology and Department of Rehabilitation at Northern Jiangsu People's Hospital between January and April 2024. Face-to-face, semi-structured in-depth interviews were conducted. Data were analyzed and thematically extracted using Colaizzi seven-step method.Results:Each interview lasted between 25 and 47 minutes, totaling 547 minutes of interview time and approximately 92 000 words of transcription. A total of 3 major themes were identified: characteristics of risk perception regarding additional injury during motor rehabilitation, multidimensional influencing factors of risk perception, and perceived severity of additional injury.Conclusions:Stroke patients with hemiplegia exhibit diverse and dynamic risk perception characteristics regarding additional injury during motor rehabilitation, which are influenced by multiple interrelated factors. A generally low and inaccurate level of risk perception was observed. Medical staff should pay greater attention to improving the accuracy of patients' risk perception, enhancing risk assessment mechanisms, and developing targeted prevention strategies to help patients avoid additional injuries and maximize the benefits of motor rehabilitation.
