Objective:To investigate the clinical application effect of enhanced recovery after surgery(ERAS) in the perioperative period of primary repair for children with hypospadias.Methods:Non-randomized controlled study.Retrospective analysis was made on clinical data of 206 children with hypospadias admitted to the Department of Urology, Shanxi Children′s Hospital from March 2018 to March 2022.According to whether the concept of ERAS was adopted for perioperative management of children, they were divided into the ERAS group(109 cases) and the non-ERAS group(97 cases). t-test and Chi-square test were used to analyze the differences between the two groups of patients in hospitalization days, hospitalization costs, pain scores on the first day after surgery, average number of bowel movements within 5 days after surgery, first out-of-bed activity time, hospital satisfaction score, and complication rate. Results:Pediatric patients in the ERAS group showed better outcomes compared to the non-ERAS group: shorter hospital stays[(7.71±1.12) d vs.(21.00±1.07) d], lower hospitalization costs[(10 043.21±1 341.00) yuan vs.(12 993.44±1 081.00) yuan], lower postoperative pain scores on the first day[(5.21±1.32) points vs.(6.09±1.07) points], more frequent bowel movements within 5 days[(5.16±0.65) times vs.(2.91±0.48) times], earlier time to first out-of-bed activity[(5.03±0.61) d vs.(7.12±0.57) d], and higher hospital satisfaction scores[(4.71±0.21) points vs.(4.14±0.15) points], and the differences were statistically significant(all P<0.05).Additionally, the ERAS group had lower rates of fever(6.42%, 7/109) and constipation(3.67%, 4/109) before urinary catheter removal compared to the non-ERAS group[21.64%(21/97) and 28.87%(28/97), respectively](all P<0.05).There were no significant differences in the incidences of complications such as urethral prolapse, infection, delayed wound healing, and bleeding, as well as urethral stricture, urethral fistula, and urethral diverticulum after urinary catheter removal between the two groups(all P>0.05). Conclusions:ERAS protocol applied in the perioperative period of primary repair for children with hypospadias can shorten the hospitalization time, lower the hospitalization costs, and accelerate the rehabilitation of children.It is worth further promotion.

Neurons in the primary auditory area (AUDp) innervate multiple brain regions with long-range projections while receiving informative inputs for diverse functions. However, the brain-wide connections of these neurons have not been comprehensively investigated. Here, we simultaneously applied virus-based anterograde and retrograde tracing, labeled the connections of excitatory and inhibitory neurons in the mouse AUDp, and acquired whole-brain information using a dual-channel fluorescence micro-optical sectioning tomography system. Quantified results showed that the two types of neurons received inputs with similar patterns but sent heterogeneous projections to downstream regions. In the isocortex, functionally different areas consistently sent feedback-dominated projections to these neurons, with concomitant laterally-dominated projections from the sensory and limbic cortices to inhibitory neurons. In subcortical regions, the dorsal and medial parts of the non-lemniscal auditory thalamus (AT) were reciprocally connected to the AUDp, while the ventral part contained the most fibers of passage from the excitatory neurons and barely sent projections back, indicating the regional heterogeneity of the AUDp-AT circuit. Our results reveal details of the whole-brain network and provide new insights for further physiological and functional studies of the AUDp.

Many people affected by fragile X syndrome (FXS) and autism spectrum disorders have sensory processing deficits, such as hypersensitivity to auditory, tactile, and visual stimuli. Like FXS in humans, loss of Fmr1 in rodents also cause sensory, behavioral, and cognitive deficits. However, the neural mechanisms underlying sensory impairment, especially vision impairment, remain unclear. It remains elusive whether the visual processing deficits originate from corrupted inputs, impaired perception in the primary sensory cortex, or altered integration in the higher cortex, and there is no effective treatment. In this study, we used a genetic knockout mouse model (Fmr1^KO), in vivo imaging, and behavioral measurements to show that the loss of Fmr1 impaired signal processing in the primary visual cortex (V1). Specifically, Fmr1^KO mice showed enhanced responses to low-intensity stimuli but normal responses to high-intensity stimuli. This abnormality was accompanied by enhancements in local network connectivity in V1 microcircuits and increased dendritic complexity of V1 neurons. These effects were ameliorated by the acute application of GABA_A receptor activators, which enhanced the activity of inhibitory neurons, or by reintroducing Fmr1 gene expression in knockout V1 neurons in both juvenile and young-adult mice. Overall, V1 plays an important role in the visual abnormalities of Fmr1^KO mice and it could be possible to rescue the sensory disturbances in developed FXS and autism patients.

Objective:To investigate the high-resolution CT features and risk factors of secondary bronchiolitis obliterans (BO) in children with adenovirus pneumonia.Methods:In this study, a case-control study method was adopted, and 44 children with BO secondary to adenovirus pneumonia in Dongguan Children′s Hospital Affiliated to Guangdong Medical University from January 2015 to October 2020 were selected as the observation group, and 45 children with simple adenovirus pneumonia during the same period were selected as the control group. The differences in the chest high-resolution CT imaging characteristics of the two groups of children were compared. The risk factors of secondary BO in children with adenovirus pneumonia were analyzed by single factor and multiple factor logistic regression.Results:In the lung CT examination of children in the observation group, the detection rates of mosaic perfusion sign, bronchial wall thickening, bronchiectasis, lung consolidation and clear lung were significantly higher than those in the control group, and the difference was statistically significant (all P<0.05); Logistic regression model showed that prolonged heat course, high heat peak, mechanical ventilation treatment and prolonged mechanical ventilation time were independent risk factors of secondary BO children with adenovirus pneumonia (all P<0.05). Conclusions:Children with BO secondary to adenovirus pneumonia have typical high-resolution CT features, which is of high practical value for clinical diagnosis. Prolonged heat course, high heat peak, mechanical ventilation treatment and prolonged mechanical ventilation were independent risk factors of secondary BO in children with adenovirus pneumonia.

OBJECTIVE: To explore the genetic basis for a Chinese patient featuring cleidocranial dysplasia(CCD). METHODS: Genomic DNA was extracted from peripheral blood samples of the patient and his parents. Whole exome sequencing (WES) was carried out for the patient, and suspected variant was verified by Sanger sequencing. RESULTS: WES has identified a missense c.460G>T (p.Val154Phe) (GRCh37/hg19) variant of the RUNX2 gene. The variant was located in the Runt domain, a highly conserved region (PM1); it was not present in either the Genome Aggregation Database or the 1000 Genomes Project (PM2), and was predicted to have a deleterious effect on the gene product by multiple in silico prediction tools (PP3); the clinical phenotype of the patient was highly consistent with that of cleidocranial dysplasia (PP4). Furthermore, the variant was unreported in medical literature and was absent in both parents (PS2). Based on the American College of Medical Genetics and Genomics guidelines, the c.460 G>T variant of RUNX2 gene was predicted to be pathogenic (PS2+PM1+PM2+PP3+PP4). CONCLUSION The c.460G>T (p.Val154Phe) variant of the RUNX2 gene probably underlay the clinical phenotype in the patient. Above finding has enabled accurate diagnosis and expanded the spectrum of RUNX2 variants.

Abdominoscrotal hydrocele is rare in clinic. In the past, routine examination and diagnosis were difficult, easy to be misdiagnosed. The daily operations were mostly completed through the groin area or abdominal incision, the wound is large. The application of laparoscopy can clearly diagnose the abdominoscrotal hydrocele through "springing back ball" sign, and can cure the disease by laparoscopic resection of interperitoneal mass and closure of the internal ring. It is worthy of clinical application. In this article, we summarized and analyzed the clinical experience of 15 cases of children with abdominoscrotal hydrocele diagnosed and treated by laparoscopy, to explore the value of the laparoscopic technology in the diagnosis and treatment of the abdominoscrotal hydrocele.

OBJECTIVE: To explore the genotype-phenotype correlation in a child with Kabuki syndrome type 1 (KS1) caused by a mosaic frameshift variant of KMT2D gene. METHODS: Trio-based whole exome sequencing (WES) was carried for the patient and her parents. Candidate variant was verified by Sanger sequencing. RESULTS: The proband, a 3-year-and-2-month-old Chinese girl, presented with distinctive facial features, cognitive impairment, mild developmental delay, dermatoglyphic abnormalities, minor skeletal anomalies, ventricular septal defect, and autistic behavior. Trio-based WES revealed that the proband has carried a de novo mosaic frameshit variant of the KMT2D gene, namely NM_003482.3:c.13058delG (p.Pro4353Argfs*31) (GRCh37/hg19), for which the mosaicism rate was close to 21%. The variant was unreported previously and was confirmed by Sanger sequencing. Chromosomal microarray analysis (CMA) has revealed no pathogenic or likely pathogenic copy number variations. Compared with previously reported cases, our patient has presented obvious behavior anomalies including autism, anxiety and sleep problems, which were rarely reported. CONCLUSION This study has expanded the spectrum of KMT2D gene variants, enriched the clinical phenotypes of KS1, and facilitated genetic counseling for the family.

Objective To observe any changes in spinal cord hemodynamics after spinal cord injury and to investigate their mechanism. Methods Twenty female Sprague-Dawley rats were divided into a control group and a moderate injury group,10 rats in each group.A rat model of spinal cord injury caused by moderate compression was established using Nystrom's method.Changes in the velocity and volume of blood flow and in the diameters of vessels of the spinal cord were monitored for 6 hours using laser speckle imaging. Results No changes in the velocity or volume of blood flow or in the diameter of vessels were observed in the control group,but all of these indices diminished significantly in the injury group. Conclusions Laser speckle imaging can be used to monitor changes in spinal cord hemodynamics.Such changes after acute spinal cord injury indicate progressive post-injury ischemia.The occlusion of veins may be an important contributor to post-injury ischemia.
