Objective:To investigate the safety and efficacy of flow diverter (FD) in the treatment of middle cerebral artery (MCA) dissection aneurysms.Methods:Patients with MCA dissection aneurysm received FD treatment at the Department of Neurosurgery, Jinjiang Hospital and the Cerebrovascular Disease Center of the First Affiliated Hospital of Naval Medical University from January 2021 to December 2023 were included retrospectively. The success rate of procedure, incidence of complications, occlusion rate of aneurysms, and clinical outcome were evaluated.Results:A total of 23 patients were included, with a success rate of 100% for FD implantation and a periprocedural complication rate of 8.7%. Nineteen patients (82.6%) completed angiography follow-up within an average of 7.2 months, of which the aneurysms of 16 patients (84.2%) were completely occluded, 3 (15.8%) were partial occluded, and 2 (10.5%) experienced in-stent restenosis; 14 (73.7%) showed stenosis of covered branch openings, of which 2 (10.5%) had branch occlusions, with no relevant clinical symptoms. The median clinical follow-up time was 23.2 months, with 95.7% of patients achieving good outcome (modified Rankin scale score ≤2).Conclusion:FD is safe and effective in the treatment of MCA dissection aneurysms, and precise device selection and release is the key to improving procedural safety.

Acute kidney injury (AKI) has high morbidity and mortality, but effective clinical drugs and management are lacking. Previous studies have suggested that macrophages play a crucial role in the inflammatory response to AKI and may serve as potential therapeutic targets. Emerging evidence has highlighted the importance of forkhead box protein O1 (FoxO1) in mediating macrophage activation and polarization in various diseases, but the specific mechanisms by which FoxO1 regulates macrophages during AKI remain unclear. The present study aimed to investigate the role of FoxO1 in macrophages in the pathogenesis of AKI. We observed a significant upregulation of FoxO1 in kidney macrophages following ischemia-reperfusion (I/R) injury. Additionally, our findings demonstrated that the administration of FoxO1 inhibitor AS1842856-encapsulated liposome (AS-Lipo), mainly acting on macrophages, effectively mitigated renal injury induced by I/R injury in mice. By generating myeloid-specific FoxO1-knockout mice, we further observed that the deficiency of FoxO1 in myeloid cells protected against I/R injury-induced AKI. Furthermore, our study provided evidence of FoxO1's pivotal role in macrophage chemotaxis, inflammation, and migration. Moreover, the impact of FoxO1 on the regulation of macrophage migration was mediated through RhoA guanine nucleotide exchange factor 1 (ARHGEF1), indicating that ARHGEF1 may serve as a potential intermediary between FoxO1 and the activity of the RhoA pathway. Consequently, our findings propose that FoxO1 plays a crucial role as a mediator and biomarker in the context of AKI. Targeting macrophage FoxO1 pharmacologically could potentially offer a promising therapeutic approach for AKI.

Hepatocellular carcinoma,as a com-mon malignant tumor,remains a serious global health problem.Traditional methods such as surgi-cal resection and chemotherapy have limited ef-fects in improving the prognosis of advanced hepa-tocellular carcinoma.With the deepening of re-search into molecular mechanisms,targeted thera-py has become an important direction for the treat-ment of hepatocellular carcinoma.In this review,we summarize the main targeted drugs and associ-ated therapeutic strategies for hepatocellular carci-noma,aiming to provide references and evidence for future related research.

Objective:To evaluate the efficacy of dexmedetomidine-scalp nerve block (SNB) combined with general anesthesia in the patients with acute traumatic brain injury (TBI) undergoing craniotomy.Methods:In this randomized controlled trial, 74 American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients of either sex with acute TBI, aged 30-78 yr, with body mass index of 18-30 kg/m 2, underwent craniotomy for hematoma evacuation combined with decompressive craniectomy at the Traditional Chinese Medicine Hospital of Kunshan from January to December 2024, of the Glasgow Coma Scale score 8-12, were selected and divided into 2 groups ( n=37 each) using a random number table method: dexmedetomidine combined with ultrasound-guided SNB group (DS group) and ultrasound-guided SNB group (S group). Before anesthesia, dexmedetomidine was infused as a loading dose of 1 μg/kg over 10 min followed by an infusion of 0.3 μg·kg -1·h -1 until the end of operation. Ultrasound-guided SNB was performed after completion of intubation in both groups. The consumption of intraoperative fentanyl, propofol and remifentanil and the usage of vasoactive drugs were recorded. Before surgery (T 0), at 1 h after the start of surgery (T 1) and at the end of surgery (T 2), blood samples from the jugular bulbar and radial artery were collected, the jugular venous oxygen saturation was recorded, the arteriovenous oxygen content and cerebral oxygen uptake rate were calculated, and the occurrence of postoperative complications was also recorded. Results:Compared with group S, the consumption of fentanyl, propofol and remifentanil was significantly reduced, the usage rate of vasoactive drugs was decreased, the arteriovenous oxygen content and cerebral oxygen uptake rate were decreased at T 1 and T 2, the jugular venous oxygen saturation was increased, and the incidence of postoperative agitation was decreased in group DS ( P<0.05). Conclusions:Dexmedetomidine-SNB combined with general anesthesia can optimize the analgesic effect, improve cerebral oxygen supply and demand, reduce the occurrence of postoperative agitation when used in patients with acute TBI undergoing craniotomy.

Lung cancer represents as one of the most prevalent malignant tumors globally,necessitating the urgent identification of additional biomarkers to facilitate precise stratified treatment and elevate its survival rates.Previous studies have focused on the correlation between the histopathological characteristics,driver gene mutations,and progno-sis of non-small cell lung cancer(NSCLC),with the aim of predicting the potential molecular background,treatment efficacy,and possible clinical outcomes of patients from the morphological perspective.This article aims to briefly sum-marize the advancements in emerging histopathological indicators of NSCLC,and discuss their implications for guiding the prognosis of this disease.

Hepatocellular carcinoma(HCC),commonly known as primary liver cancer,is a major cause of malignant tumors and cancer-related deaths in China,accounting for approximately 85％of all cancer cases in the country.Several guidelines have been used to diagnose and treat liver cancer.However,these guidelines provide a broad definition for classifying advanced liver cancer,with an emphasis on a singular approach,without considering treatment options for individual patients.Therefore,it is necessary to establish a comprehensive and practical expert consensus,specifically for China,to enhance the diagnosis and treatment of HCC using the Delphi method.The classification criteria were refined for Chinese patients with HCC,and the corresponding optimal treatment regimen recommendations were developed.These recommendations took into account various factors,including tumor characteristics,vascular tumor thrombus grade,distant metastasis,liver function status,portal hypertension,and the hepatitis B virus replication status of patients with primary HCC,along with treatment prognosis.The findings and rec-ommendations provide detailed,scientific,and reasonable individualized diagnosis and treatment strategies for clinicians.
