Within the prefrontal-cingulate cortex, abnormalities in coupling between neuronal networks can disturb the emotion-cognition interactions, contributing to the development of mental disorders such as depression. Despite this understanding, the neural circuit mechanisms underlying this phenomenon remain elusive. In this study, we present a biophysical computational model encompassing three crucial regions, including the dorsolateral prefrontal cortex, subgenual anterior cingulate cortex, and ventromedial prefrontal cortex. The objective is to investigate the role of coupling relationships within the prefrontal-cingulate cortex networks in balancing emotions and cognitive processes. The numerical results confirm that coupled weights play a crucial role in the balance of emotional cognitive networks. Furthermore, our model predicts the pathogenic mechanism of depression resulting from abnormalities in the subgenual cortex, and network functionality was restored through intervention in the dorsolateral prefrontal cortex. This study utilizes computational modeling techniques to provide an insight explanation for the diagnosis and treatment of depression.

Objective:To analyze the clinical characteristics and evaluate the effect and safety of anti-vascular endothelial growth factor (VEGF) therapy in retinopathy of prematurity (ROP) in Sichuan province.Methods:A retrospective study. From January 2013 to January 2022, 156 patients (306 eyes) with ROP who received intravitreal anti-VEGF therapy for the first time in the Department of Ophthalmology, West China Hospital of Sichuan University were selected. According to the type of anti-VEGF drugs, the children were divided into intravitreal injection of ranibizumab (IVR) group and intravitreal injection of conbercept (IVC) group; IVC group was divided into hospital group and referral group according to the different paths of patients. After treatment, the patients were followed up until the disease degenerated (vascular degeneration or complete retinal vascularization) or were hospitalized again for at least 6 months. If the disease recurred or progressed, the patients were re-admitted to the hospital and received anti-VEGF drug treatment, laser treatment or surgical treatment according to the severity of the disease. Clinical data of these children was collected, including general clinical characteristics: gender, gestational age at birth (GA), birth weight (BW), history of oxygen inhalation; pathological condition: ROP stage, zone, whether there were plus lesions; treatment: treatment time, postmenstrual gestational age at the time of the first anti-VEGF drug treatment; prognosis: re-treat or not, time of re-treatment, mode of re-treatment; adverse events: corneal edema, lens opacity, endophthalmitis, retinal injury, and treatment-related systemic adverse reactions. The measurement data between groups were compared by t test, and the count data were compared by χ2 test or rank sum test. Results:Of the 306 eyes of 156 children with ROP, 74 were male (47.44%, 74/156) and 82 were female (52.56%, 82/156). Each included child had a history of oxygen inhalation at birth. The GA was (28.43±2.19) (23.86-36.57) weeks, BW was (1 129±335) (510-2 600) g, and the postmenstrual gestational age was (39.80±3.04) (31.71-49.71) weeks at the time of the first anti-VEGF drug treatment. All patients were diagnosed as type 1 ROP, including 26 eyes (8.50%, 26/306) of aggressive ROP (A-ROP), 39 eyes (12.74%, 39/306) of zone Ⅰ lesions, and 241 eyes (78.76%, 241/306) of zone Ⅱ lesions. The children were treated with intravitreal injection of anti-VEGF drugs within 72 hours after diagnosis. Among them, 134 eyes (43.79%, 134/306) of 68 patients were treated with IVR, and 172 eyes (56.21%, 172/306) of 88 patients were treated with IVC. In IVC group, 67 eyes of 34 patients (38.95%, 67/172) were in the hospital group and 105 eyes of 54 patients (61.05%, 105/172) were in the referral group. 279 eyes (91.18%, 279/306) were improved after one treatment, 15 eyes (4.90%, 15/306) were improved after two treatments, and 12 eyes (3.92%, 12/306) were improved after three treatments. The one-time cure rate of IVR group was lower than that of IVC group, but the difference was not statistically significant ( χ2=1.665, P=0.197). In different ROP categories, IVC showed better therapeutic effect in A-ROP, and its one-time cure rate was higher than that in IVR group, with statistically significant difference ( χ2=7.797, P<0.05). In the hospital group of IVC group, the GA, BW and the postmenstrual gestational age at first time of anti-VEGF drug treatment were lower than those in the referral group, and the difference was statistically significant ( t=-2.485, -2.940, -3.796; P<0.05). The one-time cure rate of the hospital group and the referral group were 94.94%, 92.38%, respectively. The one-time cure rate of the hospital group was slightly higher than that of the referral group, but the difference was not statistically significant ( χ2=0.171, P=0.679). In this study, there were no ocular and systemic adverse reactions related to drug or intravitreal injection in children after treatment. Conclusions:Compared with the characteristics of ROP in developed countries, the GA, BW and postmenstrual gestational age of the children in Sichuan province are higher. Both IVR and IVC can treat ROP safely and effectively. There is no significant difference between the two drugs in the overall one-time cure effect of ROP, but IVC performed better in the treatment of A-ROP in this study.

Objective:To reveal the expression and regulation network of microRNA (miRNA) and mRNA in ovarian endometriosis using high-throughput sequencing, and then explore the potential pathogenesis.Methods:From January 2017 to January 2018, twenty patients with ovarian endometriosis in Xiangya Hospital of Central South University were enrolled. Ectopic endometrium and paired eutopic endometrium were collected when surgery was conducted. After total RNA was extracted, miRNA sequencing and mRNA sequencing were performed respectively. Differential miRNA and mRNA expression profiles were analyzed. Predicted mRNA were obtained by Targetscan and miRDB databases, and then intersected with differential mRNA to obtain candidate mRNA. miRNA-mRNA regulatory network was analyzed using Cytoscape software, whereas gene ontology (GO) and pathway function enrichment were performed by DAVID database.Results:Compared with eutopic endometrium, there were 369 miRNAs (197 up-regulated, 172 down-regulated) and 3 765 mRNAs (1 975 up-regulated and 1 790 down-regulated) differentially expressed in ectopic endometrium. Real time quantitative polymerase chain reaction (qRT-PCR) confirmed that the expression of mir-202-5p and mir-514a-5p in ectopic endometrium was higher than that in eutopic endometrium ( P<0.05), while the expression of mir-375-3p, mir-449b-5p in ectopic endometrium was lower than that in eutopic endometrium ( P<0.05). Bioinformatics found that the candidate mRNA related to these four miRNAs are mainly enriched in biological processes of nuclear steroid hormone receptor binding, transmembrane receptor and protein kinase activity, and participate in transforming growth factor β (TGF β) signal pathway, adhesion junction, Wnt signal pathway and Rap1 signal pathway. Conclusions:miRNA and mRNA are differentially expressed in endometriosis, and exact important regulatory network in the development of endometriosis by involving multiple biological processes.

Objective The number of children diagnosed with autism spectrum disorder (ASD)has increased dramatically in the past years.Parents of children with ASD usually experience a variety of chronic and acute stressors that may decrease marital satisfaction and family functioning.The aim was to explore the characteristics of parental per-sonality,mood disorders and family functions of the Children with ASD and to explore the relevance factors in order to draw out methods to improve parental family functions.Methods A cross -sectional survey was conducted and 593 outpatients with ASD diagnosed in Shanghai Mental Health Center,Shanghai Jiao Tong University School of Medicine form January 201 0 to January 201 4 were straight into the group,their parents were tested by Family Assessment Device (FAD),Zung Self -Rating Depression Scale(SDS),Zung Self -Rating Anxiety Scale(SAS)and Eysenck Personality Questionnaire(EPQ).SPSS 1 7.0 software was adopted to establish the database and statistical analysis.Results Ac-cording to FAD,parents of children with ASD had lower scores in problem solving[(2.1 0 ±0.37)scores]and roles [(2.09 ±0.27)scores](t =-6.669,P =0.000;t =-1 8.707,P =0.000)than the standard scores,while other di-mensions score were significantly higher than the standard scores in communicdtion[(2.25 ±0.35)scores],emotional reaction[(2.38 ±0.40)scores],emotional involvement[(2.36 ±0.37)scores],behavioral control[(2.31 ±0.27) scores]and general function[(2.1 2 ±0.38)scores],there were significant differences(t =3.1 35,1 1 .1 1 5,1 6.997, 37.1 1 6,8.064;P =0.002,0.000,0.000,0.000,0.000).For EPQ of parents,mother had obviously higher scores than father in psychoticism scale[(53.68 ±1 .36)scores vs (52.65 ±1 .1 7)scores,t =-1 3.841 ,P =0.000],and signifi-cantly lower scores in Lie scale[(52.27 ±0.79)scores vs (52.1 7 ±0.75)scores,t =2.449,P =0.01 4].Compared to fathers,mothers were coded as higher depression and anxiety scores(t =-6.276,-6.440,all P =0.000)and higher prevalence rate(χ2 =1 5.893,27.592,all P =0.000),which were statistically significant.According to the asso-ciation study of FAD and the others(especially in mood of parents),it was found that several dimensions showed obvious correlation.Conclusions Parents of children with ASD have family function damaged badly,except for prob-lem solving and roles.The parents showed different personality traits and mood disorders,particularly mothers′mood disorder problem was prominent.Parental family functioning were closely related to their personality traits and emotional disorders in various dimensionalities,which was worthy of attention.
