BackgroundCurrently， the problem of depressed mood in college students is becoming more prominent. The experience of childhood maltreatment is a significant contributor to depression among college students. Although the association between the two has been confirmed， the specific psychosocial mechanisms underlying how childhood maltreatment affects college students' mental health remain insufficiently evidenced. ObjectiveTo explore the mediating role of emotion regulation difficulties in the relationship between childhood maltreatment and depression among college students， and to investigate the moderated effects of psychological resilience and family socioeconomic status， aiming to provide references for improving depressive symptoms in college students. MethodsOn 14 March 2024， a cluster sampling method was employed to recruit 751 college students from a university in Heilongjiang Province. Participants were assessed with Childhood Trauma Questionnaire （CTQ）， Difficulties in Emotion Regulation Scale （DERS）， Patients' Health Questionnaire Depression Scale-9 item （PHQ-9）， 10-item Connor-Davidson Resilience Scale （CD-RISC-10） and Family Socioeconomic Status Questionnaire. Pearson correlation analysis was adopted to examine the correlation between the scores of scales. Model 4 and model 7 in Process 4.2 were used to test the mediating effects of emotional regulation difficulties and the moderated effects of psychological resilience and family socioeconomic status. Results① A total of 712 （94.81%） valid questionnaires were collected. ② College students' CTQ score was positively correlated with DERS score and PHQ-9 score （r=0.296， 0.507， P<0.01）， and negatively correlated with CD-RISC-10 score and Family Socioeconomic Status Questionnaire score （r=-0.148， -0.229， P<0.01）. ③ The indirect effect value of difficulties in emotion regulation on the relationship between childhood maltreatment and depression was 0.091 （95% CI： 0.018~0.046）， accounting for 17.95% of the total effect. ④ The first half of the mediation model "childhood maltreatment → difficulties in emotion regulation → depression" （childhood maltreatment → difficulties in emotion regulation） was moderated by psychological resilience （β=-0.030， t=-6.147， 95% CI： -0.040~-0.020） and family socioeconomic status （β=-0.051， t=-3.929， 95% CI： -0.077~-0.026）. ConclusionChildhood maltreatment exerts both a direct effect on college students' depression and an indirect effect through emotion regulation difficulties. The childhood maltreatment → emotion regulation difficulties pathway in this mediation model is moderated by psychological resilience and family socioeconomic status. ［Funded by Qiqihar Medical University Graduate Student Innovation Fund Project （number， QYYCX2023-48）； Special Research Fund Project for Young Doctors of Qiqihar Academy of Medical Sciences （number， QMSI2021B-08）］

Objective:To explore the clinical manifestations and surgical outcomes of pediatric epilepsy patients with epileptic spasms (ES) as the main form of seizure, so as to analyze the correlative factors with prognosis and improve the understanding of the operation and preoperative positioning for such patients.Methods:The clinical data of patients with ES who underwent surgery therapy from June 2014 to December 2015 in Pediatric Epilepsy Center, Peking University First Hospital were collected and retrospectively analyzed.Demographic characteristics, seizure forms, etiology, electroencephalogram (EEG), cranial magnetic resonance imaging (MRI), operative methods, pathological findings as well as surgical outcomes evaluated by Engel classification during follow-up of the subjects were collected.Correlative factors with the prognosis were explored by comparing the data between patients with optimal outcome (Engel Ⅰ) and those with poor outcomes (Engel Ⅱ-Ⅳ).Results:A total of 25 pediatric patients were enrolled, including 16 males (64.0%) and 9 females (36.0%). The age of onset was (0.81±0.68) years, the age at operation was (2.98±1.63) years, and the course of disease was (2.17±1.48) years.Besides, 84.0% (21/25 cases) of the ES patients had multiple forms of seizures and partial seizure (19 cases) was the most common.MRI of the heads of all the children showed definite lesions, including 11 patients (44.0%) with lesions limited to one brain lobe and 14 patients (56.0%) involving multiple brain lobes or hemisphere.The most common etiology was focal cortical dysplasia (13 cases), followed by intracranial developmental tumors (3 cases). All patients underwent resection surgery, including resection of lesion (3 cases), single brain lobe resection (9 cases), multiple brain lobe dissection (3 cases) and hemisphere dissection (10 cases). During a follow-up period of 4.0 to 5.5 years, 1 patient was lost.Among the remaining 24 cases, 18 (75.0%) cases achieved good outcomes and wee classified as EngelⅠ, 2 cases (8.3%) and 4 cases(16.7%) were classified as Engel Ⅱand Ⅳ, respectively.The univariate comparison between the good epilepsy prognosis group and the poor epilepsy prognosis group showed that, patients whose EEG abnormalities are consistent with the anatomical lesions during the inter ictal tend to have good prognosis( P=0.006). Conclusions:(1) Optimal therapeutic effects were observed in ES patients with definite lesions treated by surgical therapy.(2) Interictal EEG consistent with the lesion side may suggest a good prognosis for surgical treatment.(3) Structural causes should be screened as soon as possible if a patient with ES is drug-refractory and presents clues of focal origin.

Objective:To investigate the clinical characteristics, surgical methods, complications and prognosis of children younger than 1 year old who had definite epileptogenic lesions under 1 year old.Methods:A total of 14 children with definite epileptogenic lesions and underwent radical surgery in Pediatric Epilepsy Center of Peking University First Hospital from March 2017 to July 2019 were selected.Their clinical data including operation age, course of disease, etiology, physical examinations, seizure types, seizure frequency, features of interictal electrocorticography(EEG), surgical methods, antiepileptic drugs, and pathology were collected and analyzed.Postoperative efficacy was eva-luated using Engel grading.The Griffiths neurodevelopmental scale and the Peabody motor developmental scale were used to assess motor neurodevelopment.Results:The operation age of 14 children was 119 to 358 days (median: 281 days), and the course of disease ranged from 119 to 352 days (median: 266 days). The age of onset was from 0 to 135 days was (median: 7.5 days), and the postoperative follow-up time was 0.5-2.0 years(median: 1.5 years). None of the patients had seizure recurrence at the last follow-up.During the follow-up period, 1 patient had recurrence, but deve-loped no seizures anymore after drug administration.Cognitive and motor functions improved during follow-up in all children.All the children had no serious complications such as postoperative infection and hydrocephalus.Conclusions:Young children with definite epileptogenic lesions have an early onset of seizures, which has a great influence on development.Multidisciplinary preoperative evaluation shows that surgery is a safe way to terminate progression of seizures, thus helping children to well develop and reducing the use of antiepileptic drugs.

ObjectiveTo investigate the expression of TESTIN gene in endometrial carcinoma and explore the functions of this gene in tumor development and progression.MethodsqRT-PCR and immunochemical staining assay were used to determine the mRNA and protein level of TESTIN in the tumor tissues,and the relationship between TESTIN expression and clinical pathology characteristics was analyzed.Results Compared to normal tissue,76.5％ (52/68) tumor tissues showed TESTIN reduced ( P ＜ 0.01 ),furthermore,this reduction in the subgroup of endometrioid adenocarcinoma was significant,but it was rarely observed in the subgroup of serous papillary adenocarcinoma.ConclusionsTESTIN was obviously down regulated in endometrail carcinoma,especially in endometrioid adenocarcinoma,which indicated TESTIN played an important role in tumorigenesis of uterine.
