ABSTRACT
Objective:To analyze the risk factors for asparaginase-associated pancreatitis (AAP) in children with acute lymphoblastic leukemia (ALL) after treatment with pegaspargase and evaluate the predictive value of pediatric sequential organ failure assessment (SOFA) score, pediatric acute pancreatitis severity (PAPS) score, Ranson′s score and pediatric Ministry of Health, Labour and Welfare of Japan (JPN) score for severe AAP.Methods:Cross-sectional study.The clinical data of 328 children with ALL who received pegaspargase treatment in the Department of Pediatric Hematology, Zhujiang Hospital, Southern Medical University from January 2014 to August 2021, as well as their clinical manifestations, laboratory examinations, and imaging examinations were collected.The SOFA score at the time of AAP diagnosis, PAPS score and Ranson′s score at 48 hours after AAP diagnosis, and JPN score at 72 hours after AAP diagnosis were calculated, and their predictive value for severe AAP was evaluated by the receiver operating characteristic (ROC) curve.Results:A total of 6.7%(22/328) of children had AAP, with the median age of 6.62 years.AAP most commonly occurred in the induced remission phase (16/22, 72.7%). Three AAP children were re-exposed to asparaginase, and 2 of them developed a second AAP.Among the 22 AAP children, 16 presented with mild symptoms, and 6 with severe symptoms.The 6 children with severe AAP were all transferred to the Pediatric Intensive Care Unit (PICU). There were no significant differences in gender, white blood cell count at first diagnosis, immunophenotype, risk stratification, and single dose of pegaspargase between the AAP and non-AAP groups.The age at diagnosis of ALL in the AAP group was significantly higher than that in the non-AAP group ( t=2.385, P=0.018). The number of overweight or obese children in the AAP group was also higher than that in the non-AAP group ( χ2=4.507, P=0.034). The areas under the ROC curve of children′s JPN score, SOFA score, Ranson′s score, and PAPS score in predicting severe AAP were 0.919, 0.844, 0.731, and 0.606, respectively.The JPN score ( t=4.174, P=0.001) and the SOFA score ( t=3.181, P=0.005) showed statistically significant differences between mild and severe AAP. Conclusions:AAP is a serious complication in the treatment of ALL with combined pegaspargase and chemotherapy.Older age and overweight or obesity may be the risk factors for AAP.Pediatric JPN and SOFA scores have predictive value for severe AAP.
ABSTRACT
Objective:To investigate the risk factors of post-stroke depression (PSD) in patients with first acute stroke 6 months after onset.Methods:Three hundred and sixty-seven patients with acute stroke who were treated for the first time in the Affiliated Hospital of Xuzhou Medical University were selected retrospectively. After onset for 6 months, the patients were followed up and divided into PSD group and non-PSD group. The clinical data, blood index, imaging data, degree of nerve damage and the patient's stigma level were compared between the two groups.Results:Totally 182 and 185 cases were included in the PSD and non-PSD groups, respectively. The incidence of PSD at 6 months post-stroke was 49.6% (182/367). The results of univariate analysis showed that diseased region, drinking history, monthly income, standard of culture, serum cortisol, total cholesterol (TC), high sensitivity C-reactive protein (hs-CRP), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), Stigma Scale for Chronic Illness-8 Chronic Disease Stigma Scale-8(SSCI-8) scores, National Institute of Health Stroke Scale (NIHSS) scores and subtype of stroke were risk factors for PSD ( P<0.05). Binary Logistic regression analysis showed that diseased region at frontal lobe ( OR = 3.245, P = 0.011), basal ganglia region ( OR = 2.820, P = 0.007), cerebellar hemisphere ( OR = 4.594, P = 0.010) and serum cortisol ( OR = 1.174, P<0.001), hs-CRP ( OR = 1.057, P<0.001), SSCI-8 scores ( OR = 1.674, P<0.001), NIHSS scores ( OR = 1.283, P<0.001) were independent risk factors for PSD. Conclusions:PSD is a common complication in patients with stroke. Diseased region (at frontal lobe, basal ganglia region, cerebellar hemispheres), hs-CRP, serum cortisol, level of morbidity stigma and degree of neurological impairment are development risk factors for the PSD at 6 months of acute stroke.
ABSTRACT
This study aims to optimize the teaching design of Nutritional Counseling and Education, a core course for registered dietitians in China, to strengthen the cultivation of practical nutrition counseling and education abilities of nutritional professionals in China, and to provide reference for other colleges and universities intending to offer the same type of courses. This study thoroughly examined the course design of Nutrition Counseling and Education in four universities in the United States, and compared it with the course design in Shanghai Jiao Tong University School of Medicine. A profound comparison revealed that our course design was basically in line with that of the United States in terms of knowledge and ability cultivation objectives as well as the contents, teaching modes, and performance evaluation methods of theoretical and practical courses. However, there were slight deficiencies in our course design in terms of the integration of theoretical and practical courses, as well as the diversity and depth of practical courses. Our course design can be optimized by developing online teaching resources, drafting practical guidance manuals, increasing the number of practice bases, and enriching the modality and content of practical courses.
ABSTRACT
ObjectiveTo explore the synergetic effect of temperature and PM2.5 on cardiovascular and cerebrovascular diseases. MethodWe collected cardiovascular and cerebrovascular death cases，air pollution and meteorological data during the same period in Pudong New Area from 2013 to 2018.We used generalized additive models （GAMs） with poisson regression including non-stratification model， nonparametric bivariate response model and pollution-stratified parametric model， to assess the interaction between temperature and PM2.5 and on the number of cardiovascular cerebrovascular and cerebrovascular disease deaths. ResultsThe exposure-response relationship between temperature and the number of cardiovascular and cerebrovascular deaths exhibited "U" type and the most comfortable temperature was 18.9 ℃. When the concentrations of PM2.5 increased by 10 μg·m-3， the deaths of total， male， female， ≤75 years and >75 years increased， respectively， by 0.60%（95%CI： 0.30%‒0.91%）， 0.77%（95%CI：0.34%‒1.20%）， 0.46%（95%CI：0.05%‒0.86%）， 0.66%（95%CI：0.03%‒1.30%） and 0.59%（95%CI：0.26%‒0.92%）. With the increase of PM2.5 concentration level， the impact of temperature on cardiovascular and cerebrovascular diseases gradually increased， and the impact was the most significant when the concentration of PM2.5 was more than 150 µg·m-3. There were different sensitive people in different seasons. ConclusionPM2.5 concentration levels of mild pollution and above can exacerbate the negative effects of temperature on cardiovascular and cerebrovascular diseases.

ABSTRACT
@#Objective To investigate the clinical efficacy of preoperative location of pulmonary nodules guided by electromagnetic navigation bronchoscopy (ENB). Methods Patients who received preoperative ENB localization and then underwent surgery from March 2021 to November 2022 in the Department of Thoracic Surgery, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine were collected. The clinical efficacy and safety of ENB localization and the related factors that may affect the success of ENB localization were analyzed. Results Initially 200 patients were included, among whom 17 undergoing preoperative localization and biopsy were excluded and a total of 183 patients and 230 nodules were finally included. There were 62 males and 121 females with a mean age of 49.16±12.50 years. The success rate of navigation was 88.7%, and the success rate of ENB localization was 67.4%. The rate of complications related to ENB localization were 2.7%, and the median localization time was 10 (7, 15) min. Multi-variable analysis showed that factors related to successful localization included distance from localization site (OR=0.27, 95%CI 0.13-0.59, P=0.001), staining material (OR=0.40, 95%CI 0.17-0.95, P=0.038), and staining dose (OR=60.39, 95%CI 2.31-1 578.47, P=0.014). Conclusion ENB-guided preoperative localization of pulmonary nodules is safe and effective, and the incidence of complications is low, which can be used to effectively assist the diagnosis and treatment of early lung cancer.
ABSTRACT
Objective@#To prepare a composite membrane by chitosan/β-sodium glycerophosphate(CS/β-GP) thermosensitive hydrogel combined with stromal cell derived factor-1(SDF-1) and observe its biological characteristics in vitro.@*Methods@#Different doses of SDF-1 were added into CS/β-GP solution and then the thermosensitive gel time was measured. The SDF-1/CS/β-GP solution was membrane paved and dried to prepare composite membranes. The morphological characteristics were observed by scanning electron microscope(SEM). Composite membranes were placed into cell culture medium, and the supernatant(n=3) was extracted after standing at 6, 12, 24, 36, 48, 60 h, respectively. The concentration of SDF-1 in the solution was measured. Bone mesenchymal stem cells(BMSCs) were cultured in the Transwell room, and the composite membranes containing different concentrations of SDF-1 were placed in the lower chamber. There were four groups(n=3): Group M0 used CS/β-GP membrane(control group), Group M1, M2, M3 used SDF-1/CS/β-GP membrane(SDF-1 was 100, 200, 400 ng/mL respectively). After culture for 6, 12 and 24 h, the cells under the membrane were preserved and Giemsa stained and counted. The absorbance(OD) value was measured by MTT method to calculate the cell proliferation rate. SPSS 19.0 was used for multi-factor analysis of variance.@*Results @#After adding a certain amount of SDF-1 into CS/β-GP solution, the gel time did not change significantly(P>0.05). The SDF-1/CS/β-GP membrane was translucent and porous at 37 ℃. In this experiment, the volumic mass of SDF-1 released by SDF-1/CS/β-GP composite membrane increased gradually with the experimental time(P<0.01). Transwell cell chemotaxis test showed that the number of BMSCs cells with directional migration increased with the prolongation of observation time(P<0.01) and the increase of SDF-1 volumic mass(P<0.01). In MTT test, the OD value of migration cell solution increased with the prolongation of time(P<0.01) and the increase of SDF-1 volumic mass(P<0.01). @*Conclusion@# The SDF-1/CS/β-GP composite membrane has a porous structure and biological activity of chemotactic BMSCs directional migration. It is a potential membrane for guided tissue regeneration.
ABSTRACT
Objective:To investigate the risk factors and prognoses of cerebral venous sinus thrombosis (CVST) caused by pegasparaginase (PEG-Asp).Methods:A total of 252 children with acute lymphoblastic leukemia (ALL) were treated with PEG-Asp chemotherapy in our hospital from December 2016 to July 2021, including 8 children with CVST. The clinical manifestations, laboratory and imaging features, treatments and prognoses of these children with CVST caused by PEG-Asp were analyzed retrospectively.Results:(1) CVST occurred during induction chemotherapy in 4 children, during re-induction chemotherapy in 3 children, and during consolidation stage in one child. CVST occurred in two children who received PEG-ASP chemotherapy once, in one child who received PEG-Asp chemotherapy twice, and 5 children who received PEG-Asp chemotherapy more than twice. The median time between CVST occurrence and last treatment of PEG-Asp was 20.5 d. (2) The clinical manifestations included paroxysmal headache ( n=4), nausea or vomiting ( n=3), convulsions ( n=2) and persistent blurred vision ( n=1). (3) CVST appeared at the sigmoid sinus ( n=6), transverse sinus ( n=4) and superior sagittal sinus ( n=4), of which one child was complicated with hemorrhage in left frontal parietal and right parietal cortex, and one with reversible posterior encephalopathy syndrome; 8 children were not complicated with thrombus in other parts. (4) Some of the children were complicated with abnormal blood coagulation. When CVST occurred, fibrinogen level decreased in 3 children, anti-thrombin III level decreased in 2 children, and D-dimer level increased in 3 children. (5) Six children were treated with low molecular weight heparin (LMWH), of which, 4 were treated with rivasaban and one with warfarin sequentially. The total course of anticoagulation was 56 d. (6) The symptoms of 6 children disappeared after anticoagulation; Magnetic resonance venography (MRV) showed disappeared thrombus in 4 children and reduced thrombus range in 2 children. One child with intracranial hemorrhage did not use PEG-Asp anymore; 7 accepted PEG-Asp further during follow-up chemotherapy, of which one had CVST recurrence and the range of thrombus was reduced after anticoagulant therapy. Conclusions:When children with ALL develop unexplained neurological symptoms during PEG-Asp chemotherapy, CVST should be highly vigilant. Enhanced MRI and MRV should be performed for early diagnosis. Some children are complicated with abnormal blood coagulation, and LMWH, warfarin and rivasaban are effective. The prognosis is good and there are no sequelae. Most children accepted PEG-Asp again will not have CVST again.
ABSTRACT
Objective:To analyze the competence assessment examinations of registered dietitians in China during 2017-2021 to inform the training of dietetic professionals.Methods:A systematic review was conducted about the composition and changing trends of examination participants during 2017-2021. Participants were divided into subgroups based on gender, age, education, professional background and affiliations and the qualification rate was compared across different subgroups.Results:The number of examination participants showed an increasing trend overall, with the majority being females and aged 26-35 years. The ratio of participants with bachelor's: master's: doctor's degree was about 15: 9: 1. The proportion of participants majoring in nutrition science decreased from 32.1% to 20.3%, while that of participants majoring in other medical and food sciences increased. Among participants from healthcare institutions, a decreasing proportion of participants were with a major in nutrition science, while this proportion among participants from companies were stable at 38.8% to 50.2%. The average qualification rate was 35.7%, showing no significant differences among different gender and age groups. But the qualification rate varied significantly across subgroups with different education level, professional background, and affiliations ( P < 0.05). Subgroups with more advanced degrees showed higher qualification rate and the best rate was observed in the subgroups with professional background in nutrition science and from nutrition-related institutions. Conclusion:The training of dietetic professionals in China should be improved, lifelong learning should be promoted in nutrition practitioners, and the sustainable development of dietitians should be impelled.
ABSTRACT
Objective:To observe the effect of edaravone dexborneol on anxiety and depression after stroke in rats, and to explore its possible mechanism.Methods:Totally 120 healthy adult male SD rats were randomly divided into sham operation group (sham), ischemia-reperfusion group (MCAO), edaravone group (Eda) and edaravone dexborneol group (ED) with 30 in each group.The middle cerebral artery occlusion (MCAO) model was established by thread occlusion.Rats in ED group and Eda group were intraperitoneally injected with edaravone(8 mg·kg -1·d -1) and edaravone dexborneol(edaravone: 8 mg·kg -1·d -1, dexborneol: 2 mg·kg -1·d -1) respectively.And rats in the other two groups were intraperitoneally injected with the same volume of normal saline.Some rats were killed after continuous administration for 3 days to detect molecular indexes, and the remaining rats were tested for behavior after continuous administration for 14 days.The levels of neclear factor κB(NF-κB)、phosphorylated NF-κB(p-NF-κB)、tumor necrosis α(TNF-α)、interleukin 1β(IL-1β) were detected by Western blot.The mRNA levels of TNF-α, IL-1β, cluster of differentiation 86(CD86), cluster of differentiation 206(CD206), inducible nitric oxide synthase(iNOS) were detected by RT-qPCR.M1 type microglia labeled with CD68, microglia labeled with ionized calcium binding adaptor molecule 1(Iba1) and neurons labeled with microtubule-associated protein 2(MAP2) were detected by immunofluorescence staining.The cerebral infarction volume was measured by TTC staining.Depression and anxiety behavior after stroke in rats was observed by the open field test and elevated plus maze test.SPSS 17.0 software was used for statistical analysis of the data.One-way ANOVA was used for multiple group comparison, and LSD-t test was used for pairwise comparison. Results:(1) The behavioral results showed that 14 days after ischemia-reperfusion, the number of entering into the open arm, the time spent in the open arm, and the time spent in the central area of the open field in the MCAO group were lower than those in the sham group ( t=20.77, 6.02, 14.63, all P<0.05). The number of entering into the open arm, the time spent in the open arm, and the time spent in the central area of the field in the ED group ( (16.22±0.49) times, (69.11±17.08) s, (3.80±0.37) s) were higher than those in the MCAO group ( (8.14±0.60) times, (41.18±9.81) s, (0.33±0.39) s) ( t=4.69, 0.38, 2.27, all P<0.05) and Eda group ( (11.11±0.26) times, (45.26±17.16) s, (1.14±0.19) s) ( t=8.63, 2.50, 7.86, all P<0.05). (2) Western blot results showed that 3 days after ischemia-reperfusion, p-NF-κB/NF-κB, TNF-α, and IL-1β levels in the MCAO group were higher than those in the sham group ( t=15.35, 12.35, 7.23, all P<0.05). The levels of p-NF-κB/NF-κB (0.49±0.02), TNF-α (0.73±0.03), IL-1β (0.61±0.01) of ischemic penumbra cortex in ED group were significantly lower than those of the MCAO group ( (1.14±0.05), (1.13±0.07), (1.34±0.14)) ( t=14.58, 7.86, 5.65, all P<0.05) and Eda group ( (0.93±0.03), (0.89±0.02), (1.04±0.36) ) ( t=9.82, 3.07, 3.30, all P<0.05). (3) RT-qPCR results showed that the level of TNF-α mRNA (1.98±0.18), IL-1β mRNA (2.00±0.35), CD86 mRNA (1.56±0.20) and iNOS mRNA (2.01±0.12) in the peri-infarct cortex of ED group were lower than those in the MCAO group ( (5.12±0.24), ( 8.15±0.22), (6.03±0.13), (7.20±0.09) ) ( t=7.86, 16.88, 16.55, 37.25, all P<0.05) and Eda group ( (2.85±0.07), (5.43±0.26), (2.67±0.27), (3.58±0.11) ) ( t=3.71, 9.41, 4.13, 11.30, all P<0.05). The level of CD206 mRNA in the peri-infarct cortex of the ED group (3.98±0.25) was higher than that in the MCAO group (2.00±0.11) ( t=7.08, P<0.05) and Eda group (3.17±0.09) ( t=3.25, P<0.05). (4) The results of immunofluorescence staining showed that the ratio of polarized M1 microglia in the peri-infarct cortex and striatum in the ED group ((20.36±9.23)%, (18.26±5.98)%)were lower than those in the MCAO group ( (83.69±12.79)%, (61.25±33.26)%) ( t=5.23, 3.02, both P<0.05) and Eda group((42.16±13.13)%, (40.23±14.22)%)( t=3.12, 2.08, both P<0.05). In addition, the number of neurons marked with MAP2 of peri-infarct cortex in the MCAO group was lower than that in the sham group( t=8.02, P<0.05), and the number of neurons marded with MAP2 of peri-infarct cortex in the ED group ((53.07±17.90) /scope) was higher than that in the MCAO group ( (26.27±9.95) /scope) ( t=6.89, P<0.05) and Eda group ( (38.69±12.03)/scope) ( t=5.26, P<0.05). (5) The results of TTC staining showed that the cerebral infarction volume in ED group ( (10.31±1.03)%) was lower than that in the MCAO group ( (34.71±1.74)%) ( t=15.31, P<0.05) and Eda group ( (26.05±1.00)%) ( t=9.88, P<0.05). Conclusion:Edaravone dexborneol can alleviate anxiety and depression in rats with cerebral ischemia-reperfusion, which may be related to the inhibition of M1 microglial polarization, the down-regulation of NF-κB signaling pathway and the enhancement of neuronal structural stability.

ABSTRACT
Objective@#To investigate the situation of social sports activities and the relationship with depression among junior middle school students, to provide evidence for depression intervention.@*Methods@#A total of 3 623 students from eight middle schools in Chengdu were recruited and surveyed by self-made questionnaire during Sept. to Dec. 2019 Z test, Chi-Square test and Logistic regression analysis were applied to explore influence factors.@*Results@#The prevalence of depression symptoms was 45.60%. 57.34% of the students liked social sports activities, 65.87% of them participated in social sports activities during the past week, 42.25% took less than 30 minutes on exercise while 22.24% took over 45 minutes. Among the students, 20.16% of them had no special feeling after social sports activities, while 31.88% felt sweat. Uni-variate analysis indicated that compared with boys, girls participated more frequently and got stronger feeling than boys (χ2/Z=6.28，-2.67，P<0.05). Regression results indicated that for boys, high grade,low education degree of mother, low household socioeconomic status, not the only-child ,exercise alone would significantly increase the risk of depression, while liking social sports activities was protective factor (OR=1.26，1.91，1.52，2.56，1.58，1.71，0.77，P<0.05). For girls, high grade,low education degree of father, without one-child would significantly increase the risk of depression, while like social sports activities was protective factor(OR=1.29，1.74，1.37，1.47，0.66，P<0.05).@*Conclusion@#Social sports activities could reduce depression symptoms, which can be considered as first choice as after-class activity among junior middle school students.
ABSTRACT
@#Surgery is an essential method of comprehensive treatment for lung cancer, but it also impairs patients’ cardiopulmonary function. A subset of patients who undergo surgery may suffer from postoperative complications, and even death. Preoperative pulmonary rehabilitation is a part of enhanced recovery after surgery, and can improve patients' cardiopulmonary function, reduce postoperative complication rate and shorten hospital stay. It has been already demonstrated a great value in lung cancer surgery. In this review, we summarized the three important components of preoperative pulmonary rehabilitation, including smoking cessation, chest physical therapy, and preoperative exercise training. Moreover, this review outlined the development of pulmonary rehabilitation for lung malignancies, aiming to promote its application and standardization.
ABSTRACT
@#Segmentectomy is the removal of certain segments of the lung with lesions and retaining the normal lung tissue of the lobe. Lung segmentectomy is considered difficult due to the lack of clear anatomical boundaries between lung segments. Segmentectomy has a variety of indications, such as lung cancer, metastatic lung tumors, and many non-malignant diseases. In the treatment of early stage lung cancer, segmentectomy was initially considered only as a treatment option for patients not suitable for conventional lobectomy. As more evidence emerged, the indications for segmentectomy have continued to change over time, and segmentectomy has been widely performed in patients with early stage lung cancer. Theoretically, segmentectomy leads to better preservation of lung function than lobectomy, but the risk of incomplete tumor resection is higher, so the indication of segmentectomy has become a focus of debate. This article will introduce the surgical techniques of segmentectomy and summarize the published and unpublished clinical studies on segmentectomy for the treatment of early stage lung cancer.
ABSTRACT
@#Objective To explore the risk factors for lymph node metastasis in patients with T2 stage non-small cell lung cancer. Methods The clinical data of 271 patients with non-small cell lung cancer who underwent surgical treatment in our hospital from 2014 to 2017 were collected, including 179 males and 92 females, with an average age of 62.73±0.58 years. The patients were divided into N0, N1, and N2 groups according to the lymph node metastasis status. The clinical data of the patients in different groups were compared. Results The body mass index (BMI, P=0.043), preoperative lymph node enlargement (P<0.001), and tumor diameter (P<0.001) were significantly different among groups. The BMI (OR=1.131, 95%CI 1.001-1.277, P=0.048) and preoperative lymph node enlargement (OR=3.498, 95%CI 1.666-7.342, P=0.001) were independent risk factors for N2 lymph node metastasis, and tumor diameter was an independent risk factor for both N1 (OR=1.538, 95%CI 1.067-2.218, P=0.021) and N2 (OR=1.814, 95%CI 1.196-2.752, P=0.005) lymph node metastasis. Conclusion Patients with high BMI or enlarged lymph nodes before surgery have a high risk for N2 lymph node metastasis, and those with large tumor diameter have a high risk for both N1 and N2 lymph node metastasis.
ABSTRACT
@#Objective To analyze the risk factors for complications after robotic segmentectomy. Methods Clinical data of 207 patients undergoing robot-assisted anatomical segmentectomy in our hospital from June 2015 to July 2019 were retrospectively analyzed, including 69 males and 138 females with a median age of 54.0 years. The relationship between clinicopathological factors and prolonged air leakage, pleural effusion, and pulmonary infection after surgery was analyzed. Results After robot-assisted segmentectomy, 20 (9.7%) patients developed prolonged air leakage (>5 d), 17 (8.2%) patients developed pleural effusion, and 4 (1.9%) patients developed pulmonary infection. Univariate logistic regression showed that body mass index (BMI, P=0.018), FEV1% (P=0.024), number of N1 lymph nodes resection (P=0.008) were related to prolonged air leakage after robot-assisted segmentectomy. Benign lesion was a risk factor for pleural effusion (P=0.013). The number of lymph node sampling stations was significantly related to the incidence of pulmonary infection (P=0.035). Multivariate logistic analysis showed that the BMI (OR=0.73, P=0.012) and N1 lymph node sampling (OR=1.38, P=0.001) had a negative and positive relationship with prolonged air leakage after robot-assisted segmentectomy, respectively. Conclusion The incidence of pulmonary complications after robot-assisted segmentectomy is low. The lower BMI and more N1 lymph node sampling is, the greater probability of prolonged air leakage is. Benign lesions and more lymph node sampling stations are risk factors for pleural effusion and lung infection, respectively. Attention should be paid to the prevention and treatment of perioperative complications for patients with such risk factors.
ABSTRACT
Objective:To explore the relations among childhood trauma,autistic traits and dysexecutive functions in college students.Methods:Totally 2757 college students were assessed with the Childhood Trauma Questionnaire (CTQ).Sixty-three college students were randomly selected as the abused group according to the subscale cutoff point of CTQ Scale defined by Bernstein,and 93 students were randomly selected from students without history of childhood trauma as the control group.They were assessed with the Self-Rating Depression Scale (SDS),Autism Spectrum Quotient (AQ) and Dysexecutive Questionnaire (DEX) to measure depression,autistic traits and abnormality of executive functions,respectively.The individuals from the top and below 27％ of CTQ and AQ scores were defined as higher or lower-level different types of abused group and higher or lower-level autistic traits group,respectively.Results:The differences of DEX scores between higher or lower-level four types of CTQ (emotional abuse,physical abuse,sexual abuse,emotional neglect and physical neglect) and between higher or lower-level autistic traits group were significant (Ps ＜0.05).DEX scores in all higher-level groups were higher than all lower-level groups.Regression analysis showed that DEX score could be positively predicted by scores of emotional abuse,AQ and SDS (β =0.17-0.32,P ＜0.05).SDS score was a mediator between scores of emotional abuse and DEX,and between scores of autistic traits and DEX (95％ confidence interval were 0.05-0.32 and 0.07-0.55,respectively).Conclusion:Childhood trauma and autistic traits may positively predict dysexecutive function,and depression may play a mediating role between emotional abuse and dysexecutive function,and between autistic traits and dysexecutive function.
