N-acetyl-p-aminophenol （APAP） is an antipyretic analgesic commonly used in clinical practice， and APAP overdose can cause severe liver injury and even death. In recent years， the incidence rate of APAP-induced liver injury （AILI） tends to increase， and it has become the second most common cause of liver transplantation worldwide. Autophagy is a highly conserved catabolic process that removes unwanted cytosolic proteins and organelles through lysosomal degradation to achieve the metabolic needs of cells themselves and the renewal of organelles. A large number of studies have shown that autophagy plays a key role in the pathophysiology of AILI， involving the mechanisms such as APAP protein conjugates， oxidative stress， JNK activation， mitochondrial dysfunction， inflammatory response and apoptosis. This article elaborates on the biological mechanism of autophagy in AILI， in order to provide a theoretical basis for the treatment of AILI and the development of autophagy regulators.

ObjectiveTo explore the mechanism of Huoxue Rongluo prescription （HXRLP） in repairing the blood-brain barrier （BBB） after ischemic stroke （IS）. MethodsMale C57BL/6 mice were randomly divided into sham operation （Sham） group， cerebral infarction model （MCAO） group， environmental circadian disruption with cerebral infarction model （ECD-MCAO） group， low-， medium-， and high-dose HXRLP （HXRLP-L， M， and H） groups （8.5， 17， 34 g·kg^-1·d^-1， respectively）， and positive drug butylphthalide （NBP） group （0.23 mL·d^-1）. In the Sham group， only the exposed blood vessels were isolated without suture insertion. In the other groups， the middle cerebral artery occlusion （MCAO） model of mice was prepared. In the ECD-MCAO group， HXRLP groups， and NBP group， the environmental circadian disruption （ECD） model was prepared. The mice in the Sham group， MCAO group， and ECD-MCAO group were given the same volume of soybean oil by gavage， while those in the other groups were given the corresponding drugs by gavage. Samples were collected after 7 consecutive days of administration. The mNSS score was used to evaluate the repair effect of HXRLP on neurological deficits after IS. Hematoxylin-eosin （HE） staining was used to assess the impact of HXRLP on the pathological damage of brain tissue after IS. 2，3，5-Triphenyltetrazolium chloride （TTC） staining and cerebral blood perfusion status were used to evaluate the repair effect of HXRLP on brain tissue damage after IS. Evans blue staining and transmission electron microscopy were used to evaluate the improvement effect of HXRLP on the permeability injury of BBB after IS. Immunofluorescence （IF） staining was used to observe the expression of von Willebrand Factor （vWF）， brain and muscle Arnt-like 1 （Bmal1）， and Occludin in brain tissue. Western blot was used to detect the protein expression of Bmal1， Occludin， tight junction protein （Claudin-5）， vascular endothelial growth factor （VEGF）， and angiopoietins（Ang）， and related analysis was conducted. ResultsCompared with the Sham group， the MCAO group exhibited significantly aggravated neurological deficits， cerebral infarction volume， brain pathological damage， and BBB leakage （P0.01） and significantly reduced cerebral blood perfusion （P0.01）. The expression of Bmal1， vWF， vascular endothelial growth factor A （VEGFA）， and Ang in brain tissue was significantly enhanced （P0.01）， while the expression of Occludin and Claudin-5 was significantly weakened （P0.01）. Compared with the MCAO group， the ECD-MCAO group showed significantly aggravated neurological deficits， cerebral infarction volume， and BBB leakage （P0.01）， obviously worsened brain pathological damage （P0.05）， significantly reduced cerebral blood perfusion （P0.01）， and significantly decreased expression of Bmal1， vWF， VEGFA， Ang， Occludin， and Claudin-5 in brain tissue （P0.01）. Compared with the ECD-MCAO group， the HXRLP groups of all doses presented significantly improved neurological deficits， cerebral infarction volume， brain pathological damage， and BBB leakage （P0.01）， significantly increased cerebral blood perfusion （P0.01）， and enhanced expression levels of Bmal1， vWF， VEGFA， Ang， Occludin， and Claudin-5 in brain tissue （P0.01）. ConclusionHXRLP can regulate the clock protein Bmal1 and promote the expression of VEGFA， Ang， Occludin， and Claudin-5， thereby improving BBB damage after IS.

OBJECTIVE: To explore the current status and changing trends of the disease burden of traumatic brain injury (TBI) in China from 1990 to 2023, and to quantitatively assess the impact of different influencing factors on this disease burden, thereby providing references for the prevention of TBI. METHODS: Based on the 2023 Global Burden of Disease Study (GBD), indicators including incidence and years lived with disability (YLDs) were used to analyze the status and changing trends of TBI disease burden in China from 1990 to 2023. Additionally, the decomposition method established by Gupta was adopted to quantify the effects of population growth, population aging, age-specific incidence rate, and disease severity on YLDs. RESULTS: From 1990 to 2023, the age-standardized incidence rate and YLDs rate of TBI in China showed an overall upward trend, with a significant downward trend between 2015 and 2020, followed by a resumption of upward trend after 2020. The disease burden of TBI in males was higher than that in females, with a larger increase amplitude. The elderly population had higher TBI incidence rate and YLDs rate, also with a larger upward amplitude. Falls were the main cause of TBI in China, and the changing trend of the disease burden caused by falls was consistent with the overall trend of TBI disease burden; meanwhile, the elderly population bore a relatively high disease burden from falls. Taking 1990 as the baseline, the growth rates of YLDs in males and females in 2023 were 101.54% and 101.40%, respectively. For males, the proportions of YLDs growth attributed to population growth, population aging, age-specific incidence rate, and disease severity were 26.91%, 49.62%, 37.74%, and -12.73%, respectively; for females, the corresponding proportions were 28.85%, 57.69%, 27.65%, and -12.79%. CONCLUSION From 1990 to 2023, population aging had a significant impact on the disease burden of TBI in China. Strengthening the prevention and control of falls and paying close attention to males and the elderly population should be the key focuses of TBI prevention and control work in China in the future.

Objective:This study was aimed to evaluate the clinical effectiveness of tympanoplasty using auricular cartilage combined with balloon eustachian tuboplasty for the treatment of adhesive otitis media（adhesive otitis media, AdOM） under endoscopic. Methods:A retrospective analysis was conducted on 60 patients with unilateral adhesive otitis media who visited Department of Otolaryngology Head and Neck Surgery, the First Affiliated Hospital of Xiamen University between January 2017 and February 2022. All patients were divided into three groups: ①conservative treatment group;②simple tympanoplasty group; ③tympanoplasty combined with balloon dilation group（BET group）. All patients were regularly assessed for the improvement of tympanic membrane morphology, hearing, and Eustachian tube function, as well as complications, after treatment. Results:There was no significant improvement in eardrum morphology, hearing, or eustachian tube function in the conservative treatment group（P>0.05）; both the simple tympanoplasty group and the BET group showed significant improvements in eardrum morphology and hearing after surgery（P<0.01）; In terms of Eustachian tube function improvement, the BET group showed significantly greater improvements in Eustachian tube manometry（TMM） and Eustachian Tube Dysfunction Questionnaire（ETDQ-7） scores compared to the tympanoplasty alone group（P<0.01）. Conclusion:Tympanoplasty using auricular cartilage combined with balloon eustachian tuboplasty shows good clinical outcomes in the treatment of adhesive otitis media, significantly ameliorating patients' subjective symptoms such as tinnitus and ear congestion after surgery, thereby improving the patient's quality of life.

Objective To investigate the distribution characteristics of treatment time for total marrow irradiation (TMI) or total marrow and lymphoid irradiation (TMLI) based on helical tomotherapy, establish a time parameter framework for the application of TMI/TMLI techniques, and provide a basis for optimizing clinical treatment efficiency, predicting patient tolerance, and streamlining workflow. Methods A retrospective analysis was conducted on 57 patients who received TMI/TMLI using helical tomotherapy between November 2024 and July 2025. Patients were stratified by height ( ≤ 130 cm group vs. > 130 cm group). Megavoltage computed tomography scanning time, beam-on time, and total treatment time were recorded. The relationship between height and treatment time was analyzed using Spearman correlation analysis. An independent samples t-test was used to compare treatment time between TMI and TMLI modes. Results In the ≤ 130 cm group, the mean megavoltage computed tomography scanning time, beam-on time, and total treatment time per fraction were (9.67 ± 1.47), (39.96 ± 9.08), and (49.63 ± 10.16) minutes, respectively. In the > 130 cm group, the corresponding times were (14.52 ± 1.17), (60.45 ± 11.19), and (74.97 ± 11.82) minutes, respectively. Treatment time was positively correlated with height (r = 0.756, P < 0.001). Among patients taller than 130 cm, there was no statistically significant difference in treatment time between the TMI and TMLI (P > 0.05). Conclusion Although helical tomotherapy requires a relatively long treatment time, its technical characteristics are well-suited for the extensive and complex target volumes involved in TMI/TMLI. Future technological upgrades and standardized stratification hold promise for enhancing both efficiency and precision, thereby expanding clinical applicability.

Objective:To evaluate the clinical effect of bispherical augment in acetabular defects reconstruction in hip revision.Methods:This is a retrospective case series study. A retrospective analysis of 119 patients (124 hips) patients who underwent hip revision surgery and reconstructed with bispherical augment for acetabular bone defects from January 2019 to December 2023 was performed. There were 57 males (58 hips) and 62 females (66 hips), aged (65.0±11.8) years (range:40 to 102 years). The body mass index was (23.9±3.5) kg/m 2 (range:16.1 to 32.2 kg/m 2). Acetabular bone defects were typed as follows: 2 hips in Paprosky type ⅡA, 29 hips in type ⅡB, 34 hips in type ⅡC, 31 hips in type ⅢA, and 28 hips in type ⅢB, of which 9 patients (9 hips) were combined with pelvic discontinuity. Differences in Harris hip score (HHS) and lower limb discrepancy (LLD) were compared between preoperatively and final follow-up. The height of the hip center of rotation and the horizontal distance from the center of rotation to the teardrop were measured by radiographs before and after surgery, and prothesis stability and the occurrence of postoperative complications were evaluated. Data were compared using the paired sample t test. Results:All patients successfully completed the operation. The operation time was (167.0±53.4) minutes (range:90 to 380 minutes) and the intraoperative bleeding was (345.3±124.2) ml (range:100 to 1 200 ml). The height of the hip center of rotation decreased from (39.7±13.0) mm preoperatively to (21.8±7.1) mm postoperatively and the horizontal distance from the center of rotation to the teardrop increased from (34.0±10.1) mm preoperatively to (38.5±5.9) mm postoperatively, and the differences were statistically significant ( t=15.859, P<0.01; t=5.266, P<0.01). All the patients were followed up for (26.1±15.4) months (range:6 to 60 months). At the last follow-up, HHS improved from (35.2±10.0) points preoperatively to (85.5±9.5) points, and the difference was statistically significant ( t=50.723, P<0.01). LLD decreased from (2.1±1.1) cm preoperatively to (0.5±0.5) cm, and the difference was statistically significant ( t=13.767, P<0.01). All acetabular components were stable and free of displacement on imaging during follow-up. Three patients suffered dislocation and received closed reduction, all prosthesis were in good position during follow-up. No dislocation, loosening, fracture, recurrence of infection and vascular nerve injury occurred in other patients. Conclusion:Bispherical augment can effectively reconstruct acetabular bone defects, restore the hip center of rotation, and improve hip joint function scores at short and mid-term follow-up.

Objective:To compare the effect of anesthesia mode on the neurological functional outcomes in patients undergoing endovascular treatment for acute posterior circulation ischemic stroke.Methods:Clinical data of 656 patients undergoing intravascular therapy for acute posterior circulation ischemic stroke registered in online Acute Stroke Patients for Stroke Management Quality Evaluation Database from January 2017 to December 2022 were retrospectively analyzed.The data included 163 cases with conscious sedation and 493 cases with general anesthesia during the procedure.After propensity score matching,428 patients were included in the analysis,including 155 cases in the conscious sedation group and 273 cases in the general anesthesia group.The differences of operation mode,etiology type,vascular recanalization,hemorrhagic transformation at 24 h,modified Rankin Scale(mRS)score at 3 months and mortality within 3 months were compared between the two groups.Binary logistic regression was used to explore the effect of different anesthesia mode on neurological functional outcomes.Results:There was a significant difference in operation mode between the two groups(P<0.01),while there were no significant differences in etiology type,vascular recanalization,hemorrhagic transformation at 24 h,mRS score at 3 months or mortality within 3 months(all P>0.05).Binary logistic regression analysis revealed that anesthesia modes were not significantly associated with functional outcomes of patients(OR=1.151,95%CI:0.751-1.765,P>0.05).Conclusion:Anesthesia mode(conscious sedation or general anesthesia)will not affect the neurological functional outcomes in patients with acute posterior circulation ischemic stroke undergoing endovascular treatment.
