Article Synopsis
  • - The study evaluated a commercial AI-powered X-ray bone age analyzer's effectiveness compared to the Tanner-Whitehouse 3 (TW-3) method, finding that the AI system is both accurate and efficient in assessing bone age in children and adolescents.
  • - It used radiographs from 900 patients across 30 centers in China, with six doctors independently assessing the images alongside the AI, which performed better on average than one of the raters and matched performance with others in terms of accuracy.
  • - The AI analyzer achieved an impressive mean absolute error (MAE) of around 0.48 years for bone age estimates, suggesting it could enhance clinical workflow by significantly reducing the time required for evaluations.

With an increasing understanding of growth hormone deficiency, there has been a growing emphasis on the management of transition growth hormone deficiency (TGHD) in clinical practice. The inadequate diagnosis and treatment of TGHD have been a major clinical concern, leading to the development of relevant guidelines and consensus internationally. This article summarizes the evaluation, diagnosis, treatment, and clinical challenges of TGHD based on these guidelines, consensus, and existing clinical studies, aiming to optimize and further improve the clinical diagnosis, treatment, and management of TGHD.

Context: The evidence of long-term polyethylene glycol recombinant human GH (PEG-rhGH) in pediatric GH deficiency (GHD) is limited.

Objective: This study aimed to examine the effectiveness and safety of long-term PEG-rhGH in children with GHD in the real world, as well as to examine the effects of dose on patient outcomes.

Design: A prospective, observational, posttrial study (NCT03290235).

Background: A Y-shaped rotatable connector (YRC) for double-lumen tubes (DLT) is invented and compared with the traditional connector (Y-shaped connector, YC).

Methods: Sixty patients with ASA grade I-III, aged ≥ 18 years, who needed to insert a DLT for thoracic surgery were recruited and assigned into the YRC group (n = 30) and the YC group (n = 30) randomly. The primary endpoints included the inhaled air concentration (Fi) and the exhaled air concentration (Et) of sevoflurane before and after the switch between two-lung ventilation and one-lung ventilation at different times, positioning time, and switching time.

Background: Coffin-Siris syndrome (CSS) is a rare autosomal dominant disorder characterized by intellectual disability, developmental delay, and characteristic facial features. Few patients with cutaneous phenotype in this rare syndrome have been reported.

Case Presentation: Herein, we describe a 12-year-old Chinese girl diagnosed with CSS, who was referred to our hospital because of intellectual disability and short stature.

Article Synopsis
  • Pyruvate carboxylase deficiency (PCD) is a rare genetic disorder with symptoms like developmental delays and elevated levels of pyruvate and ammonia.
  • A novel splice-site variant (c.1825+5G>A) in the pyruvate carboxylase gene was identified in a 20-month-old Chinese boy diagnosed with PCD through whole-exome sequencing.
  • The study confirmed that this variant affects mRNA splicing, leading to the retention of part of the intron, establishing it as a pathogenic variant that aids in the genetic diagnosis of PCD.

Objectives: To study the clinical features and fibroblast growth factor receptor 3 () gene mutations of children with achondroplasia (ACH) through an analysis of 17 cases.

Methods: A retrospective analysis was performed on the clinical data and gene detection results of 17 children with ACH who were diagnosed from January 2009 to October 2021.

Results: Of the 17 children with ACH, common clinical manifestations included disproportionate short stature (100%, 17/17), macrocephaly (100%, 17/17), trident hand (82%, 14/17), and genu varum (88%, 15/17).

Objective: To study the association between clinical phenotypes and genotypes in children with Becker muscular dystrophy (BMD)/Duchenne muscular dystrophy (DMD) so as to provide a theoretical basis for disease management, gene therapy, and prenatal diagnosis.

Methods: A retrospective analysis was performed for the clinical data and gene detection results of 52 children with BMD/DMD. Multiplex ligation-dependent probe amplification (MLPA) was used to detect the DMD gene.

Objective: To investigate the clinical and pathological features of progressive muscular dystrophy (PMD) in children and to provide help for the early and accurate diagnosis of PMD.

Methods: Retrospective analysis was performed on the clinical data of 99 hospitalized children with PMD, including clinical manifestations, age of onset, family history, creatase, electromyogram (EMG) and pathological changes of muscles.

Results: Of the 99 children with PMD, the age of onset was 0.

Objective: To investigate the main inhalant allergens and their distribution patterns in children with allergic diseases from Xi'an and the surrounding area and to provide evidence for the prevention and treatment of allergic diseases in children.

Methods: Skin prick test was performed using liquid with 13 standardized allergens (ALK-ABELL, Denmark) on 3085 children from Xi'an and the surrounding area who were treated for allergic diseases between July 2006 and July 2011, to detect inhalant allergens.

Results: Of the 3085 patients, 1368 (44.

Objective: To study the efficacy of erythropoietinin (EPO) in the treatment of moderate or severe hypoxic-ischemic encephalopathy (HIE) in neonates.

Methods: Seventy neonates with moderate or severe HIE were randomly assigned to two groups: EPO treatment and control (n=35 each). The EPO treatment group included 22 cases of moderate HIE and 13 cases of severe HIE.

We previously found that there was up-regulation of APMCF1 expression in apoptotic MCF-7 cells. Moreover, bioinformatics analysis has found that APMCF1 molecules had similar size and structure with molecules which belong to small G-protein superfamily. We presume that APMCF1 plays certain biological role in the regulation of cell proliferation and apoptosis.

Background & Objective: apr-1 was cloned by improved polymerase chain reaction (PCR)-based subtractive hybridization from all-trans retinoic acid (ATRA)-induced apoptotic leukemia HL-60 cells in 1999. Preliminary results showed that apr-1 might be an apoptosis-related gene (GenBank ID: NM_014061). This study was to explore the background of apr-1 through gene cloning, bioinformatic analysis, and subcellular locating.

Aim: To investigate the survivin gene expression in human hepatocellular carcinoma cell line SMMC-7721 and the effects of survivin gene RNA interference (RNAi) on cell apoptosis and biological behaviors of SMMC-7721 cells.

Methods: Eukaryotic expression vector of survivin gene RNAi and recombinant plasmid pSuppressorNeo-survivin (pSuNeo-SVV), were constructed by ligating into the vector, pSuppressorNeo (pSuNeo) digested with restriction enzymes Xba I and Sal I and the designed double-chain RNAi primers. A cell model of SMMC-7721 after treatment with RNAi was prepared by transfecting SMMC-7721 cells with the lipofectin transfection method.
