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 To investigate the clinical application value of predicting the severity of acute pancreatitis(AP)based on MRI-T2WI radiomics nomogram.Methods A total of 375 patients with AP were analyzed retrospectively,who were divided into 281 cases in the training group and 94 cases in the validation group according to the ratio of 3∶1.Based on MRI-T2WI image,man-ual segmentation was performed for the pancreatic parenchyma.The radiomics feature were selected by feature extraction and dimen-sionality reduction,the support vector machine(SVM)classifier were used to construct the radiomics model.Logistic regression analysis was used to screen out independent risk factors,and an radiomics nomogram model was constructed in combined with the Radiomics score(Radscore),and the predictive performances of the models were evaluated.Results Receiver operating characteristic(ROC)curve analysis showed that the predictive efficacy of radiomics nomogram model[training group,area under the curve(AUC)=0.893;val-idation group,AUC=0.889]was higher than that of clinical model(training group,AUC=0.799;validation group,AUC=0.809)and radiomics model(training group,AUC=0.814;validation group,AUC=0.823).Conclusion The radiomics nomogram based on MRI-T2WI radiomics features and independent risk factors has high clinical application value for the prediction of AP severity.

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.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

Purpose To investigate the clinical value of artificial intelligence(AI)quantitative parameters in predicting the invasion degree of lung adenocarcinoma with diameter≤2 cm of ground-glass density.Materials and Methods A total of 80 patients with lung adenocarcinoma with diameter≤2 cm ground-glass density confirmed by pathology from March 2019 to April 2022 were retrospectively analyzed.A total of 90 nodules were rerolled,including 8 adenocarcinomas in situ(AIS),34 minimally invasive adenocarcinomas(MIA)and 48 invasive adenocarcinomas(IAC).They were divided into the experimental group(IAC)and the control group(AIS and MIA).The differences of the AI quantitative parameters such as volume,three-dimensional length diameter,maximum area,maximum CT value,minimum CT value and average CT value were compared between two groups,and the predictive values of AI quantitative parameters for the invasion degree of lung adenocarcinoma was evaluated.Results There were statistically significant differences with age,volume,three-dimensional length diameter,maximum area,maximum CT value and average CT value between the two groups(all P<0.05),but no statistically significant differences in gender and minimum CT value(both P>0.05).Binary Logistic regression analysis showed that the three-dimensional length diameter(odd ratio=2.020,P=0.034)and the maximum CT value(odd ratio=1.008,P=0.013)were independent predictors for lung adenocarcinoma with diameter≤2 cm of ground-glass density.The regression model based on the three-dimensional length diameter and the maximum CT value had the best predictive performance,and its AUC was 0.901.When the critical value was 2.432,its sensitivity and specificity were 93.75%and 71.43%,respectively.Conclusion AI quantitative parameters have a high value in predicting the degree of invasion of lung adenocarcinoma with diameter≤2 cm of ground-glass density,and the combined model with three dimensional long diameter and maximum CT value has the highest diagnostic efficiency.

Objective:To explore the application value of ventricular intracranial pressure monitoring (V-ICPM) in the treatment of unilateral temporal lobe cerebral contusion.Methods:A retrospective cohort study was conducted to analyze the clinical data of 295 patients with unilateral temporal lobe cerebral contusion admitted to 904th Hospital of PLA Joint Support Force from January 2014 to August 2021, including 172 males and 123 females; aged 14-78 years [(46.3±14.7)years]. V-ICPM was used in 136 patients (V-ICPM group), who received surgical or non-surgical treatment according to the monitoring, while not in 159 patients (non-V-ICPM group), who received routine surgery or non-surgical treatment. The two groups were compared in terms of the rates of intracranial hematoma clearance by craniotomy, decompressive craniectomy (DC) and dehydration and osmotic therapy during hospitalization, use time of 20% mass fraction of mannitol and 30 g/L hypertonic salt, displacement rate of brain midline structure of head CT≥10 mm after discharge, rate of intracranial infection, hydrocephalus and epilepsy, and Glasgow Outcome Scale (GOS) at 6 months after discharge.Results:All patients were followed up for 6-12 months [(8.9±2.1)months]. During hospitalization, the rate of intracranial hematoma clearance by craniotomy and the rate of DC in V-ICPM group were 35.3% (48/136) and 8.1% (11/136), lower than 47.2% (75/159) and 22.0% (35/159) in non-V-ICPM group ( P<0.05 or 0.01). There was no significant difference between the two groups in the rate of dehydration and osmotic therapy or the use time of mannitol (all P>0.05). The use time of hypertonic salt in V-ICPM group was (7.2±2.5)days, more than (4.1±1.8)days in non-V-ICPM group ( P<0.05). After discharge, the displacement rate of brain midline structure of head CT in V-ICPM group was 29.4% (40/136), lower than 42.8% (68/159) in non-V-ICPM group ( P<0.05). There was no significant difference between the two groups in the rate of intracranial infection, hydrocephalus and epilepsy (all P>0.05). Six months after discharge, the good rate of GOS in V-ICPM group was 91.2% (124/136), significantly better than 81.8% (130/159) in non-V-ICPM group ( P<0.05). Conclusion:For unilateral temporal lobe cerebral contusion, V-ICPM is associated with reduced rate of craniotomy exploration and DC, decreased incidence of complications and improved prognosis of the patients in spite of longer use time of hypertonic salt.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

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.

PURPOSE: Details of patients hospitalized for asthma exacerbation in mainland China are lacking. To improve disease control and reduce economic burden, a large sample survey among this patient population is indispensable. This study aimed to investigate the clinical characteristics and outcomes of such patients.METHODS: A retrospective study was conducted on patients hospitalized for asthma exacerbation in 29 hospitals of 29 regions in mainland China during the period 2013 to 2014. Demographic features, pre-admission conditions, exacerbation details, and outcomes were summarized. Risk factors for exacerbation severity were analyzed.RESULTS: There were 3,240 asthmatic patients included in this study (57.7% females, 42.3% males). Only 28.0% used daily controller medications; 1,287 (39.7%) patients were not currently on inhaled corticosteroids. Acute upper airway infection was the most common trigger of exacerbation (42.3%). Patients with severe to life-threatening exacerbation tended to have a longer disease course, a smoking history, and had comorbidities such as hypertension, chronic obstructive pulmonary disease (COPD), and food allergy. The multivariate analysis showed that smoking history, comorbidities of hypertension, COPD, and food allergy were independent risk factors for more severe exacerbation. The number of patients hospitalized for asthma exacerbation varied with seasons, peaking in March and September. Eight patients died during the study period (mortality 0.25%).CONCLUSIONS: Despite enhanced education on asthma self-management in China during recent years, few patients were using daily controller medications before the onset of their exacerbation, indicating that more educational efforts and considerations are needed. The findings of this study may improve our understanding of hospital admission for asthma exacerbation in mainland China and provide evidence for decision-making.
