Attention deficit hyperactivity disorder (ADHD), a prevalent neurodevelopmental disorder influenced by both genetic and environmental factors, remains poorly understood regarding how its polygenic risk score (PRS) impacts functional networks and symptomology. This study capitalized on data from 11,430 children in the Adolescent Brain Cognitive Development study to explore the interplay between PRS_ADHD, brain function, and behavioral problems, along with their interactive effects. The results showed that children with a higher PRS_ADHD exhibited more severe attention deficits and rule-breaking problems, and experienced sleep disturbances, particularly in initiating and maintaining sleep. We also identified the central executive network, default mode network, and sensory-motor network as the functional networks most associated with PRS and symptoms in ADHD cases, with potential mediating roles. Particularly, the impact of PRS_ADHD was enhanced in children experiencing heightened sleep disturbances, emphasizing the need for early intervention in sleep issues to potentially mitigate subsequent ADHD symptoms.

Objective:To analyze the etiological characteristics of Clostridium ramosum DZS3717106 isolated from the blood of a patient with septic shock secondary to perianal abscess and the immunological characteristics of the patient. Methods:The isolate was subjected to morphological observation, mass spectrometry, antibiotic susceptibility testing, and 16S rRNA sequencing. Biochemical and cytological test results of the patient were collected. Flow cytometry was used to detect T cell subsets. Impacts of the virulence factors of the isolate on the host immune system were evaluated.Results:DZS3717106 was an anaerobic Clostridium with pleomorphic rod-shaped cells and spores. It was sensitive to penicillin G, piperacillin/tazobactam, and metronidazole, but resistant to clindamycin. It carried various virulence and resistance genes. The patient was immunocompromised with abnormal IL-6, IL-8, and IL-10 levels. Conclusions:Septic shock caused by Clostridium ramosum is rare, and more research is needed on the causes and epidemiology. DZS3717106 infection triggers over-activated inflammatory response in the patient, which may be closely related to the occurrence and development of septic shock.

High myopia is a refractive abnormality characterized by excessive elongation of the eye axis.The sclera,as an important part of the eye axis regulation,plays a key role in the occurrence and development of high myopia.In this pa-per,based on the domestic and international articles,the pathological changes and related regulatory molecules of the scle-ra in high myopia were systematically summarized from the features of scleral lesions in high myopia and the gene regula-tion and signaling pathways affecting the ultrastructure and mechanical properties of the sclera,thus providing a theoretical basis for the study of the pathological mechanism of high myopia.

Objective:To compare the prognosis of patients with unilateral sporadic medullary thyroid carcinoma treated by different surgical selection, and analyze the independent risk factors affecting the prognosis.Methods:One hundred and twenty-six patients at Tianjin Medical University Cancer Institute and Hospital from Feb 2011 to Oct 2018 were retrospectively divided into group A (total thyroiclectomy) and group B (unilateral lobectomy).Results:There were no significant differences in postoperative recurrence rate ( χ2=0.394, P=0.530), mortality ( χ2=3.175, P=0.146), biochemical cure rate ( χ2=0.613, P=0.434), progression free survival and overall survival ( P=0.278, 0.175) between group A and group B; Tumor diameter ≥4 cm and lateral cervical lymph node metastasis were independent risk factors affecting the overall survival. The incidence of postoperative temporary hypocalcemia ( χ2=5.068, P=0.024) and permanent hypocalcemia ( χ2=6.590, P=0.010) in group A was higher than that in group B. Conclusions:Ipsolateral thyroidectomy can be applied to patients with unilateral sporadic medullary thyroid carcinoma with similar long term prognosis and tower incidence of temporary hypocalcemia and permanent hypocalcemia compared to total thyroidectomy.

Objective:To analyze the correlations between serum thyroglobulin antibody (TgAb) and thyroid peroxidase antibody (TPOAb) and clinicopathological features in children and adolescents with papillary thyroid carcinoma (PTC).Methods:A retrospective analysis was conduced on the clinicopathological data of children and adolescents (age≤21 years old) with PTC admitted to Tianjin Medical University Cancer Hospital from 2011 to 2019, and then, we used χ 2 test or Fisher′s exact probability test to compare the differences in clinicopathological characteristics between groups with different TgAb and TPOAb status and multivariate logistic regression model analysis to evaluate independent predictors of cervical lymph node metastasis. Results:A total of 304 patients, including 89 males and 215 females, aged 5-21 years (median age 19 years), were enrolled in this study. The comparison between groups with different TgAb and TPOAb status showed that there were significant differences in gender, preoperative thyroglobulin (Tg) level, primary tumor location, number of primary tumors and maximum tumor diameter (all P<0.05), which suggested that TgAb +group ( n=81) and TPOAb +group ( n=84) had relatively better primary tumor characteristics. Patitents with TgAb +and TPOAb +were more common in females and their preoperative Tg level was mostly within the normal range, and there were significant differences in primary tumor location, number of primary tumors and maximum tumor diameter between TgAb +and TgAb -(223 cases) groups (all P<0.05). There was significant difference in the maximum tumor diameter between TPOAb +and TPOAb -(220 cases) groups ( P<0.05). Analysis of risk factors for cervical lymph node metastasis showed that independent risk factors for central lymph node metastasis were maximum tumor diameter>2 cm ( OR=2.84, 95% CI: 1.59-5.07, P<0.001) and extra-thyroid extension ( OR=0.32, 95% CI: 0.17-0.60, P<0.001), and independent risk factors for lateral neck lymph node metastasis included age≤14 years old ( OR=0.34, 95% CI: 0.18-0.67, P=0.002), preoperative Tg +( OR=2.16, 95% CI: 1.10-4.24, P=0.026) and maximum tumor diameter>2 cm ( OR=3.99, 95% CI: 2.33-6.82, P<0.001). Conclusion:It is recommended to test routinely serum TgAb and TPOAb before surgery in children and adolescents with PTC. Preoperative Tg +, age≤14 years, maximum tumor diameter>2 cm, and extra-thyroid extension are risk factors for cervical lymph node metastasis.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

Kisspeptin is an important neuropeptide regulating female reproductive function. It mainly acts on the upstream of hypothalamic gonadotropin-releasing hormone (GnRH) neurons. It binds to the corresponding receptor GPR54 on GnRH neurons to stimulate the release of GnRH, which leads to a series of subsequent activities of the reproductive axis. However, in recent years, it has been found that Kisspeptin exists not only in the central hypothalamus and pituitary, but also in the peripheral ovary, indicating that Kisspeptin not only regulates the female reproductive function in the central, but also plays a local role in the ovary. Kisspeptin is not only involved in the regulation of oocyte, granulosa cell and luteal function, but also affected by gonadotropin, photoperiod, sympathetic nerve and metabolism. This article reviews the central regulation effect and the local ovarian role of of kisspeptin.
