Objective:To investigate the value of coronary CTA (CCTA)-based traditional features and radiomics of plaque in the identification of culprit lesions that caused acute myocardial infarction (AMI).Methods:This was a retrospective multicenter study. From July 2016 to November 2023, a total of 344 patients from the Affiliated Hospital of Qingdao University (training cohort, n=184), Shandong Provincial Hospital Affiliated to Shandong First Medical University (validation cohort, n=88) and Qilu Hospital of Shandong University (test cohort, n=72) who received percutaneous coronary intervention (PCI) due to AMI and underwent CCTA within 48 hours of AMI were enrolled. The culprit plaques and non-culprit plaques were identified using a combination of electrocardiogram, CCTA, and angiographic findings. The vessel, plaque location, plaque type, Coronary Artery Disease-Reporting and Data System (CAD-RADS) score, high-risk plaque characteristics, plaque length, plaque volume, and burden were analyzed, and 1 904 radiomics features were extracted for each plaque. The traditional imaging model, the radiomics model, and the combined model were established by using multivariate Logistic regression analysis. The area under the receiver operating characteristic curve (AUC) was used to evaluate the performance of each model in identifying culprit lesions. The DeLong test was used for the comparison of AUC between every two models. The net reclassification index (NRI) was used to evaluate the incremental value of the combined model to the traditional imaging model and the radiomics model. The decision curve analysis (DCA) was used to assess the clinical net benefit of these models. A correlation heatmap was used to evaluate the correlation between the radiomics score and traditional CCTA factors. The interpretable analysis of the decision process of the combined model was performed by the Shapley Additive exPlanations (SHAP). Results:In the validation cohort and the test cohort, the AUC of the traditional imaging model developed by the vessel, plaque type, positive remodeling and CAD-RADS score was 0.898 (95% CI 0.869-0.922) and 0.881 (95% CI 0.848-0.910), respectively. The radiomics model developed by six radiomics features was 0.863 (95% CI 0.831-0.891) and 0.863 (95% CI 0.827-0.864), respectively. The AUC of the combined model was 0.930 (95% CI 0.905-0.950)and 0.919 (95% CI 0.889-0.942), respectively. In the validation cohort and the test cohort, the AUC of the combined model was higher than that of the traditional imaging model ( Z=4.013, 4.272, P<0.001) and that of the radiomics model ( Z=4.819, 3.784, P<0.001), respectively. In the validation cohort, the combined model yielded an NRI of 20.43% (95% CI 10.43%-30.44%, P<0.001) and 20.21% (95% CI 9.62%-30.80%, P<0.001) for identifying culprit lesions compared with the traditional imaging model and the radiomics model, respectively. In the test cohort, the combined model yielded an NRI of 28.05% (95% CI 16.72%-39.38%, P<0.001) and 23.57% (95% CI 13.58%-33.56%, P<0.001) for identifying culprit lesions compared with the traditional imaging model and the radiomics model, respectively. DCA showed the combined model had the highest clinical net benefit. The correlation heatmap showed the radiomics score was not correlated or only weakly correlated with traditional CCTA factors. SHAP indicated the radiomics and CAD-RADS score contributed significantly to the model. Conclusion:The CCTA-based traditional features and radiomics of plaque have favorable performance for the identification of culprit plaques in patients with AMI.

Major depressive disorder in adolescents is a serious psychiatric condition characterized by profound impairment in psychosocial functioning. Its primary symptoms include low mood, irritability, and anhedonia. Although pharmacological treatments and psychotherapy are currently recommended as first-line treatments, their effectiveness is limited, and pharmacological treatments may carry the risk of increased suicidal ideation. Therefore, exploring new, effective, and safe treatment options is an urgent priority. In recent years, intermittent theta burst stimulation (iTBS), a novel form of transcranial magnetic stimulation, has shown promising results in treating treatment-resistant depression in adults, drawing growing interest in its potential use in adolescents. iTBS modulates neural activity through magnetic stimulation of the cerebral cortex and has been shown to alleviate depressive symptoms, particularly when targeting the left dorsolateral prefrontal cortex (DLPFC). Given the high neuroplasticity of the adolescent brain during this critical developmental stage, adolescents may exhibit heightened sensitivity to iTBS, resulting in more enduring neuroregulatory effects. Research highlights the importance of precise targeting and individualized adjustment of stimulation intensity for optimal therapeutic outcomes. Additionally, accelerated iTBS (aiTBS) protocols have demonstrated faster clinical effects in treating acute or severe depression in adolescents, improving treatment adherence and partially mitigating suicidal tendencies. This review summarizes recent progress in the application of iTBS in adolescent depression, with a focus on its mechanisms, treatment parameters, and related research. The goal is to provide theoretical support and practical guidance for the clinical application of iTBS in adolescent depression care.

Objective:To investigate the clinicopathological characteristics of dedifferentiated endometrial carcinoma/undifferentiated endometrial carcinoma (DDEC/UDEC) with loss of expression of SMARCA4.Methods:A total of 10 cases with loss of expression of SMARCA4 were diagnosed at Fujian Cancer Hospital between January 2019 and December 2023. A retrospective analysis was conducted on the clinical characteristics, morphology, immunophenotype, molecular classification, and prognosis.Results:(1) Clinical characteristics: among 10 cases of DDEC/UDEC with loss of expression of SMARCA4, the patients′ age ranged from 48 to 65 years, with a median age of 56 years.Five cases were classified as International Federation of Gynecology and Obstetrics (FIGO) stages Ⅰ-Ⅱ, while the remaining five were categorized as stages Ⅲ-Ⅳ. (2) Pathological features: tumor cells exhibited poor cell adhesion, with common intravascular tumor emboli (8/10), occasional vacuolated nuclei (6/10), rhabdoid cells (4/10), and starry sky phenomenon formed by tissue cell phagocytosis apoptosis bodies or fragments (4/10). Six cases (6/10) showed loss of mismatch repair (MMR) protein expression, two cases (2/10) exhibited p53 mutant expression, and five cases (5/10) tested positive for programmed cell death ligand 1 (PD-L1). (3) Molecular subtyping: molecular subtyping revealed POLEmut in 1 case (1/10), mismatch repair deficient (MMR-d) in 5 cases (5/10), p53 abn in 1 case (1/10), and no specific molecular profile (NSMP) in 3 cases (3/10). (4) Prognosis: the follow-up period ranged from 7 to 42 months, with a median of 20 months. Five patients succumbed to the tumor, whereas the remaining five exhibited no recurrence during subsequent postoperative evaluations. The 2-year progression-free survival rates and overall survival rates were 58.3% and 52.5%, respectively.Conclusions:Loss of expression of SMARCA4 occurs in approximately 1/5 of DDEC/UDEC, which presents with an aggressive clinical course and a poor prognosis. About half of them show MMR protein loss expression and PD-L1 positive expression, suggesting that there might be benefit from treatment with immune checkpoint inhibitors.

Background Currently,the diagnosis of depressive disorder relies on symptomatology,which is greatly influenced by subjective factors such as clinicians' experience.Finding more accurate and reliable quantitative diagnostic methods is currently an urgent problem.Objective To explore the value of Fisher discriminant function based on inflammatory cytokines in the diagnosis of depressive disorder,so as to provide references for clinical diagnosis.Methods A total of 136 patients diagnosed with depressive disorder according to the Diagnostic and Statistical Manual of Mental Disorders,fifth edition(DSM-5)criteria,who underwent inpatient treatment at Hebei Mental Health Center from April 2020 to November 2020,were enrolled as study group.67 healthy participants matched for age and gender,was recruited during the same period.Serum levels of inflammatory cytokine were measured using enzyme-linked immunosorbent assay(ELISA).Fisher discriminant model was employed to establish a discriminant function for inflammatory cytokines exhibiting significant statistical differences between study group and control group,which was then validated.Results The levels of pro-inflammatory cytokines interleukin-1β(IL-1β),interleukin-6(IL-6),interferon-γ(INF-γ)and tumor necrosis factor-α(TNF-α)were higher in the study group compared with control group,with statistically significant differences(U=9.115,5.239,4.431,5.428,P<0.01).Conversely,the levels of anti-inflammatory cytokines interleukin-4(IL-4),interleukin-10(IL-10)and interleukin-13(IL-13)were lower in the study group compared with control group,with statistically significant differences(U=7.398,7.331,7.614,P<0.01).The retrospective test in Fisher discriminant function achieved a correct discrimination rate of 89.66%,and the cross validation achieved a correct discrimination rate of 88.67%.Conclusion The Fisher discriminant function developed in this study may serve as a valuable auxiliary method in the diagnosis of depressive disorder.

ObjectiveTo explore the mechanism of Jiawei Wendantang in preventing and treating diabetic atherosclerosis by observing the effect of this prescription on the nuclear factor-κB / NOD-like receptor protein 3（NF-κB/NLRP3） pathway and related inflammatory cytokines in rat model of diabetic atherosclerosis. MethodFifty-four SPF-grade rats were randomized into blank， model， atorvastatin （0.9 mg·kg^-1·d^-1）， and high-， medium-， low-dose （18.2， 9.1， 4.55 g·kg^-1·d^-1， respectively） Jiawei Wendantang groups. The rats in other groups except the blank group were modeled for diabetic atherosclerosis by intraperitoneal injection of streptozotocin and feeding with a high-sugar high-fat diet， and those in the blank group were injected with an equal dose of citric acid buffer and fed with a regular diet. The drug administration lasted for 4 weeks， and the blood glucose level in the tail vein was measured every 6 days. After the last administration， the rats were anesthetized for sample collection. Enzyme-linked immunosorbent assay was employed to measure the serum levels of interleukin-18 （IL-18）， C-reactive protein （CRP）， tumor necrosis factor-α （TNF-α）， and intercellular adhesion molecule-1 （ICAM-1）. Western blot was employed to determine the relative protein levels of NF-κB p65， NLRP3， and ICAM-1 in the abdominal aorta. Real-time quantitative polymerase chain reaction was employed to determine the mRNA levels of NLRP3 and interleukin-1β （IL-1β） in the abdominal aorta. The pathological changes in the thoracic aorta were observed by hematoxylin-eosin staining. ResultCompared with the blank group， the model group showed elevated levels of IL-18， CRP， TNF-α， and ICAM-1 in the serum and blood glucose （P<0.05， P<0.01）， up-regulated protein levels of NF-κB p65， NLRP3， and ICAM-1 （P<0.01）， and up-regulated mRNA levels of NLRP3 and IL-1β （P<0.05）. Compared with model group， Jiawei Wendantang lowered the levels of IL-18， CRP， TNF-α， ICAM-1 and blood glucose （P<0.05， P<0.01）， down-regulated the protein levels of NF-κB p65， NLRP3， and ICAM-1 （P<0.01）， and down-regulated the mRNA levels of NLRP3 and IL-1β （P<0.05， P<0.01）. Moreover， Jiawei Wendantang alleviated the pathological injuries in the thoracic aorta. ConclusionJiawei Wendantang may modulate the NF-κB/NLRP3 signaling pathway to reduce the release and adhesion of inflammatory cytokines and regulate the blood glucose level to treat diabetic atherosclerosis.

Objective:To summarize the clinical features of special portal hypertension-Abernethy malformation reported at home and abroad.Methods:The relevant literature on Abernethy malformation published at home and abroad from January 1989 to August 2021 was collected. Patients'clinical features, imaging and laboratory test results, diagnosis, treatment, and prognosis were analyzed.Results:A total of 380 cases were included from 60 and 202 domestic and foreign literatures. Among them, there were 200 cases of type I, with 86 males and 114 females, and the average age was (17.08±19.42) years, while there were 180 cases of type II, with 106 males and 74 females, and the average was (14.85±19.60) years. The most common reason for the first visit of an Abernethy malformation patient's was gastrointestinal system symptoms such as hematemesis and hematochezia caused by portal hypertension (70.56%). Multiple malformations were present in 45.00% of type Ⅰ and 37.80% of type Ⅱ patients. The most prevalent condition was congenital heart disease (62.22%, and 73.53%). Complications related to Abernethy malformation was occurred in 127 and 105 cases with type I and type II, respectively, with liver lesions in 74.02% (94/127) and 39.05% (42/105) and hepatopulmonary syndrome of 33.07% (42/127) and 39.05% (41/105), respectively. The imaging diagnosis of type I and type II Abernethy malformations were mainly based on abdominal computed tomography (59.00%, and 76.11%). Liver pathology was performed in 27.10% of patients. Blood ammonia increased by 89.06% and 87.50%, and AFP increased by 29.63% and 40.00% in laboratory findings. 9.76% (8/82) and 6.92% (9/130) died, while 84.15% (61/82) and 88.46% (115/130) had improved conditions after medical conservative, or surgical treatment.Conclusion:Abernethy malformation is a rare disease in which congenital portal vein development abnormalities lead to significant portal hypertension and portasystemtic shunt. Patients often seek medical treatment for gastrointestinal bleeding and abdominal pain. Type Ⅰ is more common in women, often associated with multiple malformations, and prone to secondary intrahepatic tumors. Liver transplantation is the main treatment method. Type Ⅱ is more prevalent in males, and shunt vessel occlusion is the first treatment choice. Overall, type Ⅱ has a better therapeutic impact than type Ⅰ.

Interleukin-17 (IL-17) plays an important role in the body′s immune response and inflammatory response.High levels of IL-17 are associated with a variety of autoimmune diseases, acute and chronic neurodegenerative diseases, and psychiatric disorders.Autism spectrum disorder (ASD) is a group of common neurodevelopmental disorders in childhood.Recent clinical and experimental studies have linked maternal immune activation (MIA) during pregnancy to the risk of ASD in offspring.Significantly increased IL-17 level is found in MIA-induced progeny ASD, which is the key factor leading to neurodevelopmental abnormalities in progeny mice.This article reviews the latest research progress on the relationship between IL-17 and progeny ASD, and provides new ideas for the prevention and treatment of ASD.
