Game-based psychological assessment utilizes game mechanisms and elements to enhance partic-ipants'motivation and improve measurement accuracy,but similar to traditional methods,it mainly focuses on static results.By integrating game-based psychological assessment with artificial intelligence technology,this paper propo-ses the paradigm of intelligent psychological assessment based on interactive environment.With analyzing dynamic process data within the game,this paradigm can accurately depict the participants'actions and results in the interac-tive context,more effectively representing individual psychological states and behavioral characteristics.This new paradigm demonstrates advancements and significant potential for development in terms of demand,data collection,and analysis techniques.

Objective To observe hierarchical differences in brain functional networks in unilateral mesial temporal lobe epilepsy(mTLE)patients with different outcomes after surgery.Methods A total of 69 unilateral mTLE patients who underwent resection of epileptogenic lesion on the affected side were retrospectively enrolled.Based on Engel classification 1 year after surgery,the patients were divided into seizure free(SF)group and non-seizure free(NSF)group.Functional connectivity gradient analysis was employed to extract principal gradient explaining the highest variance on preoperative resting-state functional MRI(rs-fMRI),then the whole-brain gradient characteristics and principal gradient values within specific functional networks were compared between groups.Results Principal gradient connected default mode network(DMN)with sensorimotor network(SMN)along a continuous axis.Compared to SF group,NSF group showed a contracted gradient range at both ends(DMN and SMN)of the functional network and weakened hierarchical differentiation,and principal gradient value of DMN was higher,while that of SMN was lower than those in SF group(both P＜0.05).Conclusion Hierarchical differences in brain functional networks in unilateral mTLE patients with different outcomes after surgery mainly present as enhanced DMN and weakened SMN in NSF ones,and the latter two might serve as important neuroimaging markers for evaluating postoperative seizure recurrence.

Objective To analyze the clinical risk factors for gastrointestinal dysfunction in patients with traumatic brain injury.Methods A retrospective analysis was conducted on clinical data of 313 cases of traumatic brain injury in our hospital from January 2022 to October 2023.According to whether gastrointestinal dysfunction occurred at admission,the patients were divided into the occurrence group(Group A,90 cases)and the non-occurrence group(Group B,223 cases).Multivariate Logistic regression was used to analyze the risk factors of gastrointestinal dysfunction.The receiver operating characteristic(ROC)curve was used to evaluate the efficacy of each factor in predicting gastrointestinal dysfunction in patients with craniocerebral injury.Results Among 313 patients,90 cases(28.75％)experienced gastrointestinal dysfunction.Logistic analysis showed that the admission GCS score was ≤8 points(OR=3.117,95％CI:1.358-7.157,P=0.007),pulmonary infection(OR=7.129,95％CI:1.889-27.377,P=0.004),intracranial infection(OR=3.152,95％CI:1.162-8.548,P=0.024),frontal lobe injury(OR=5.430,95％CI:1.481-19.915,P=0.011),abnormal serum Na levels(OR=8.482,95％CI:1.958-36.247,P=0.004),and decreased Alb(OR=3.001,95％CI:1.137-7.918,P=0.026)and elevated hs CRP(OR=3.142,95％CI:1.159-8.522,P=0.024)were independent risk factors for gastrointestinal dysfunction in patients with traumatic brain injury.The receiver operating characteristic(ROC)curve was used to evaluate the efficacy of each factor in predicting gastrointestinal dysfunction in patients with craniocerebral injury.Conclusion Admission GCS score≤8,pulmonary infection,intracranial infection,frontal lobe injury,abnormal serum Na levels,decreased Alb,and elevated hs CRP are independent risk factors for gastrointestinal dysfunction in patients with traumatic brain injury.

Objective:To investigate the current status of application of stereotactic body radiation therapy (SBRT) in China, aiming to provide reference for promoting the development of this technology.Methods:From January to March 2024, a questionnaire was designed and distributed online, targeting member units of the Professional Committee of Stereotactic Radiosurgery Treatment, which covers 175 radiotherapy units in 30 provinces and regions nationwide. The survey focused on the current application of SBRT technology and its utilization in the treatment of early-stage non-small cell lung cancer (NSCLC). A statistical description of the survey results was presented.Results:Of 175 questionnaires distributed, a total of 130 valid responses were collected, with an effective response rate of 74.3%. A total of 81.5% (106/130) of the units had implemented SBRT technology, and 99.1% of the respondents believed it was necessary to further promote SBRT technology, yet the actual training rate was only 67.0%. SBRT equipment configuration: there were a total of 267 SBRT equipment, featuring a diverse range of types, with traditional linear accelerators as the mainstays, accounting for 76.0% ( n=203), followed by 12.0% ( n=32) for TOMO, 6.4% ( n=17) for Cyber knife, 3.7% ( n=10) for Gamma knife, and proton/heavy ion equipment at 1.5% ( n=4), respectively. The percentage of units with multi-leaf collimator leaf widths ≤0.5 cm was 93.4% (99/106). The application of SBRT: the first radiotherapy unit commenced SBRT in 2000, and this technology entered a period of rapid growth after 2015, sustaining a steady increase over the past decade; SBRT technology was mainly applied in the brain, lung, liver, bone, adrenal gland, and kidney, with application rates of 97.2%, 94.3%, 86.8%, 71.7%, 56.6%, and 27.4%, respectively, while the application rates for the pancreas, metastatic lymph nodes, and other parts were less than 5%. Current status of SBRT technology application in early-stage NSCLC: 90.6% (96/106) of units had implemented SBRT; pre-treatment multi-disciplinary diagnosis and treatment accounted for 77% (74/96); the proportion of application units for peripheral and central type lung cancer lesions both exceeded 57.3%, whereas the application rate for ultra-central type and lesions > 5 cm lung cancer was less than 30%; there was significant variability in the selection of reference guidelines, dose fractionation patterns, and the concept of central type among units. Conclusions:The development of SBRT technology in China is in a period of steady growth, but several issues such as low training rate and lack of standardization still exist. The survey results provide important reference for clinical training and promotion of SBRT technology in China.

Objective To observe the impact factors of abdominal wall edema degree after high intensity focused ultrasound(HIFU)ablation for uterine leiomyoma(UL).Methods Totally 128 patients with solitary UL who underwent HIFU were retrospectively enrolled.Edema degree of abdominal wall showed on T2WI were classified into grade Ⅰ,Ⅱand Ⅲ according to the involved layers and subcutaneous indurations.Patients'general data,MRI characteristics of UL,HIFU parameters and adverse reactions were compared among grades.Multinomial logistic regression analysis was used to screen the impact factors of edema degree.Results Among 128 patients,grade Ⅰ edema was found in 79 cases(79/128,61.72%),while grade Ⅱ and Ⅲ were observed in 27(27/128,21.09%)and 22(22/128,17.19%)cases,respectively.Compared with patients with grade Ⅲ edema,those with grades Ⅰ and Ⅱ had lower body mass index(BMI),and patients with grade Ⅰ edema had decreased subcutaneous fat thickness and decreased total thickness of subcutaneous fat and muscle layers(both adjusted P＜0.05).The proportion of abdominal scars in patients with grade Ⅰedema was lower than that with grade Ⅱ(adjusted P＜0.05).No significant difference of MRI findings of UL before HIFU nor HIFU parameters was noticed among different grades of edema(all P＞0.05).BMI and abdominal scar were both impact factors for distinguishing grade Ⅰ and Ⅲ,while BMI was the impact factor for distinguishing grade Ⅱ and Ⅲ edema after HIFU for UL(all P＜0.05).Conclusion BMI and abdominal scar were both impact factors for abdominal wall edema degree after HIFU for UL.
