The incidence of intracranial aneurysms is higher in population, and the death and disability rates after rupture are extremely high. Early detection of intracranial aneurysms, prediction of rupture risk, operation program, and evaluation of treatment outcomes are all the clinical concerns. With the continuously deepening integration of artificial intelligence technology and medicine, its application in the diagnosis and treatment of intracranial aneurysms is becoming increasingly widespread. This article reviews the current application status of artificial intelligence technology in the diagnosis and treatment of intracranial aneurysms.

Objective Our study aimed to conduct genomic characterization of Salmonella strains carrying the b/aNDM-1 gene in the intestinal tract of healthy individuals.The objectives were to underscore the importance of genomic surveillance for drug resistance in both commensal and pathogenic bacteria among healthy populations,and to establish protocols for regulating drug resistance plasmids based on the completion of a comprehensive map of drug resistance plasmid genomes.Methods We performed antimicrobial susceptibility testing and employed second-and third-generation sequencing techniques to analyze Salmonella strains harboring the b/aNDM-1 gene,to surveil drug-resistant bacteria in the intestines of healthy subjects.Sequence comparison was conducted using both core-and pan-genome approaches.Concurrently,conjugation experiments were carried out to assess the efficiency of plasmid transfer.Results We isolated a carbapenem-resistant Salmonella enterica serovar Typhimurium strain from a healthy food worker in China.This strain harbored an lncHI2/lncHI2A plasmid carrying blaNDM-1 along with multiple antibiotic resistance genes(ARGs).Our findings highlight the potential for asymptomatic carriers to facilitate the transmission of ARGs.Pan-genomic analysis revealed that b/aNDM-1-positive plasmids could traverse bacterial species barriers,facilitating cross-host transmission.Conclusion This study marks the first detection of b/aNDM-1 in Salmonella strains isolated from healthy individuals.We underscore the risk associated with the transmission of conjugative hybrid plasmids carrying blaNDM-1,which have the potential to be harbored and transmitted among healthy individuals.Enhanced surveillance of drug-resistant pathogens and plasmids in the intestinal microbiota of healthy individuals could provide insights into the risk of ARG transmission and pathways for population-wide dissemination via ARG transfer factors.

OBJECTIVE: Our study aimed to conduct genomic characterization of Salmonella strains carrying the bla _NDM-1 gene in the intestinal tract of healthy individuals. The objectives were to underscore the importance of genomic surveillance for drug resistance in both commensal and pathogenic bacteria among healthy populations, and to establish protocols for regulating drug resistance plasmids based on the completion of a comprehensive map of drug resistance plasmid genomes. METHODS: We performed antimicrobial susceptibility testing and employed second- and third-generation sequencing techniques to analyze Salmonella strains harboring the bla _NDM-1 gene, to surveil drug-resistant bacteria in the intestines of healthy subjects. Sequence comparison was conducted using both core- and pan-genome approaches. Concurrently, conjugation experiments were carried out to assess the efficiency of plasmid transfer. RESULTS: We isolated a carbapenem-resistant Salmonella enterica serovar Typhimurium strain from a healthy food worker in China. This strain harbored an IncHI2/IncHI2A plasmid carrying bla _NDM-1 along with multiple antibiotic resistance genes (ARGs). Our findings highlight the potential for asymptomatic carriers to facilitate the transmission of ARGs. Pan-genomic analysis revealed that bla _NDM-1-positive plasmids could traverse bacterial species barriers, facilitating cross-host transmission. CONCLUSION This study marks the first detection of bla _NDM-1 in Salmonella strains isolated from healthy individuals. We underscore the risk associated with the transmission of conjugative hybrid plasmids carrying bla _NDM-1, which have the potential to be harbored and transmitted among healthy individuals. Enhanced surveillance of drug-resistant pathogens and plasmids in the intestinal microbiota of healthy individuals could provide insights into the risk of ARG transmission and pathways for population-wide dissemination via ARG transfer factors.

So far, the endovascular treatment of intracranial aneurysms has gone through three stages: coil embolization, stent-assisted coil embolization, and placement of flow diverter, which significantly increases the occlusion rate of intracranial aneurysms. Its safety and effectiveness have also been confirmed by many large-scale studies. However, for wide-neck bifurcation aneurysms, there are still issues of difficult treatment and poor treatment outcome. The emergence of intratumoral turbulence devices has provided a new treatment option for wide-neck bifurcation aneurysms and has achieved good short- and mid-term treatment effects. This article reviews the application of the Woven EndoBridge intratumoral turbulence device in intracranial wide-neck bifurcation aneurysms.

Objective:To investigate the efficacy and safety of Tubridge flow diverter (TFD) in the treatment of unruptured intracranial aneurysms (UIAs).Methods:The clinical data of patients with UIAs treated with TFD in the Department of Neurosurgery, Linyi People's Hospital from July 2021 to July 2023 were retrospectively analyzed. The modified Rankin Scale (mRS) was used to evaluate functional outcomes during postoperative follow-up. Digital subtraction angiography (DSA) follow-up was performed at least 3 months after procedure, and the occlusion degree of the aneurysm was assessed with the O'Kelly-Marotta (OKM) grading system.Results:A total of 52 patients (71 aneurysms) were included and 54 TFDs were successfully implanted. Forty-one patients (78.8%) were treated with TFD alone, while 11 (21.2%) were treated with TFD combined with coil embolization. One patient experienced in-stent thrombosis during the procedure, and the symptoms disappeared after medical treatment. Postoperative hemorrhage and ischemic complications occurred in each 2 cases, respectively. No patient died during the follow-up period. DSA follow-up was performed on a total of 45 aneurysms in 34 patients. The followed-up time was 8.3±3.1 months (range, 3-15 months), including 2 OKM grade A (4.4%), 11 grade B (24.4%), 1 grade C (2.2%), and 31 grade D (68.9%). At the last follow-up, 51 patients had good outcomes (mRS score 0-2), and 1 patient had poor outcome (mRS score 4).Conclusion:TFD for UIAs has a high complete occlusion rate and a low complication rate.

Objective:To compare the safety and efficacy of ticagrelor and clopidogrel in dual antiplatelet therapy for stent-assisted embolization of unruptured intracranial aneurysms.Methods:Patients with unruptured intracranial aneurysms received stent-assisted embolization in the Department of Neurosurgery, Linyi People's Hospital from January 2021 to June 2022 were retrospectively included. According to the preprocedural dual antiplatelet therapy scheme, they were divided into aspirin+clopidogrel group (clopidogrel group) and aspirin+ticagrelor group (ticagrelor group). The incidence of ischemic and bleeding events was compared between the clopidogrel group and the ticagrelor group at 3 months after procedure. Multivariate logistic regression model was used to analyze independent risk factors for postprocedural ischemic and bleeding events. Results:A total of 195 patients were included. Their age was 58.15±10.11 years and 75 were males (38.5%). There was no statistically significant difference in the incidence of bleeding events (12.8% vs. 5.9%) and ischemic events (14.9% vs. 18.8%) at 3 months after procedure between the ticagrelor group ( n=94) and the clopidogrel group ( n=101). Multivariate logistic regression analysis showed that smoking (odds ratio [ OR] 6.085; 95% confidence interval [ CI] 1.589-13.012; P=0.019], hypertension ( OR 4.547, 95% CI 1.589-13.012; P=0.005), aneurysm at the branch vessel ( OR 3.089, 95% CI 1.122-8.504; P=0.029), and the use of flow diverter ( OR 3.111, 95% CI 1.062-9.110; P=0.038) were the independent risk factors for postprocedural ischemic events. Triglycerides might be an independent risk factor for postprocedural bleeding events ( OR 1.435, 95% CI 0.989-2.082; P=0.057), but did not reach statistical significance. Conclusions:In dual antiplatelet therapy for stent-assisted embolization of unruptured intracranial aneurysms, ticagrelor and clopidogrel have the same safety and efficacy.

【Objective】 To evaluate the efficacy and safety of ureteroscope or flexible ureteroscope combined with balloon dilatation in the treatment of ureteral stricture with renal calculi in transplanted kidney. 【Methods】 The clinical data of 9 patients treated in our hospital during 2016 and 2022 were reviewed. The changes of the width of hydronephrosis, levels of creatinine and urea nitrogen, reoperation, and re-dwelling of stents were analyzed. 【Results】 One patient failed the operation because the guide wire could not be inserted, and the other 8 patients successfully completed the surgery. The stents were removed 6 to 8 weeks after surgery. During the follow-up of 8 to 48 months, no recurrence of renal calculi occurred; 5 patients had no recurrence of ureteral stricture; 3 patients (cases 4, 6, 9) underwent regular ureteral stent replacement due to hydronephrosis; the width of hydronephrosis, creatinine and urea nitrogen levels of 8 patients were significantly improved (P<0.05). 【Conclusion】 Ureteroscope/flexible with balloon dilatation is safe and effective in the treatment of transplanted kidney with ureteral stricture and kidney stones.

Objective:To design a modified S1PR3 specific agonist, GPS-725.017, and investigate its protective effect on acute lung injury by promoting macrophage clearance of bacteria.Methods:A short peptide derived from the intracellular region of S1PR3 receptor was named GPS725.017, which was modified with norleucine (Nle) and myristicacid (myr) at its N terminus. Mice were divided into the sham operation group, solvent group and GPS-725.017 treatment group. The acute lung injury model was induced by endotracheal injection of E. coli (5×10 6 CFU), and the experimental group was treated with GPS-725.017 (10 mg/kg). The 48-h survival rate of mice was recorded. After 5 h of modeling, the bacterial load and inflammatory cytokines in peripheral blood and lung were detected, and Vps34 protein content in alveolar macrophages was determined by Western blot. After 12-h of modeling, lung tissues were collected for H&E staining and pathological scores. Results:Compared with the solvent group, the survival rate of mice in the GPS-725.017 treatment group was significantly improved ( P<0.01), the bacterial CFU in blood and alveolar lavage fluid was significantly lower than that in the solvent group ( P<0.001), and the levels of TNF-α and IL-1β in blood and alveolar lavage fluid were significantly lower than those in the solvent group ( P<0.001). Western blot showed that the expression level of Vps34 protein in alveolar macrophages was significantly higher than that in the solvent group ( P<0.01). Histopathology result showed that the pathological damage of lung in the treatment group was significantly less than that in the solvent group ( P<0.001). Conclusions:The modified synthetic S1PR3 specific agonist GPS-725.017 could specifically activate the S1PR3 receptor on the membrane of alveolar macrophages and up-regulate the expression level of intracellular Vps34 protein, which can promote the removal of bacteria in alveolar macrophages, significantly reduce the degree of lung injury and improve the survival rate in ALI mice.
