Background: Difficulty in obtaining tetracycline, increased adverse reactions, and relatively complicated medication methods have limited the clinical application of the classic bismuth quadruple therapy. Therefore, the search for new alternative drugs has become one of the research hotspots. In recent years, minocycline, as a semisynthetic tetracycline, has demonstrated good potential for eradicating () infection, but the systematic evaluation of its role remains lacking.

Article Synopsis
  • Inherited neuromuscular disorder (IND) is a complex group of diseases caused by genetic mutations affecting the nervous system and muscles, making diagnosis and management challenging due to its variability.
  • The study examined three pediatric cases of IND using whole-exome sequencing (WES) for genetic investigation, uncovering novel variants in the genes associated with each case, including a first-time reported mutation.
  • Structural analysis of one identified type of variant highlighted changes in protein structure and bonding, emphasizing the study's contribution to understanding IND's mutation spectrum and aiding in accurate diagnoses and consultations.

A photocatalytic chemodivergent reaction for the selectivity formation of C-S and C-N bonds in a controlled manner was proposed. The reaction medium, either neutral or acidic, is critical to dictate the formation of 2-amino-1,3,4-thiadiazoles and 1,2,4-triazole-3-thiones from isothiocyanates and hydrazones. This is a practical protocol to achieve the chemoselectivity under mild and metal-free conditions.

Background And Aims: Current practice on infection mostly focuses on individual-based care in the community, but family-based management has recently been suggested as a better strategy for infection control. However, the family-based infection status, risk factors and transmission pattern remain to be elucidated.

Methods: From September 2021 to December 2021, 10 735 families (31 098 individuals) were enrolled from 29 of 31 provinces in mainland China to examine family-based infection, related factors and transmission pattern.

Background: Due to general unavailability and common side effects of tetracycline, the clinical application of bismuth quadruple therapy (BQT) is greatly limited. Whether amoxicillin can replace tetracycline in BQT remains unknown. This study aimed to compare the eradication rate, safety and compliance between amoxicillin-containing and tetracycline-containing BQT as a first-line regimen for Helicobacter pylori eradication.

Article Synopsis
  • HMO (Hereditary Multiple Osteochondroma) is a rare genetic disorder that causes noncancerous bone tumors to form, primarily affecting children.
  • The study involved analyzing seven children diagnosed with HMO through X-rays and genetic testing like whole exome sequencing (WES), revealing several newly identified genetic variants.
  • Findings contributed to a better understanding of the genetic landscape of HMO, providing insights for family genetic counseling and patient management.

Article Synopsis
  • Cleidocranial dysplasia (CCD) is a rare genetic condition linked to mutations in the RUNX2 gene, which affects bone and cartilage development, and commonly features clavicular hypoplasia and dental anomalies in patients.
  • A study on a 5-year-old girl revealed microdeletions in RUNX2, confirmed through whole-genome sequencing and experimental validation, leading to significant clinical symptoms such as extra teeth and osteoporosis.
  • The identified RUNX2 deletion reduces its transcription activity, impacting osteoblast differentiation, and highlights the importance of genetic testing for families with suspected CCD.

Article Synopsis
  • Congenital insensitivity to pain with anhidrosis (CIPA) is caused by mutations in the NTRK1 gene and requires further research to understand its mechanisms.
  • A study used whole-exome sequencing and molecular dynamic analysis to identify a new heterozygous mutation in NTRK1, linked to changes in protein stability and purine metabolism.
  • Results from liquid chromatography-mass spectrometry and quantitative real-time PCR indicated that this variant affects mRNA levels, enhancing understanding of CIPA's genetic basis and offering potential insights for affected families.

Objective: infection is mostly a family-based infectious disease. To facilitate its prevention and management, a national consensus meeting was held to review current evidence and propose strategies for population-wide and family-based infection control and management to reduce the related disease burden.

Methods: Fifty-seven experts from 41 major universities and institutions in 20 provinces/regions of mainland China were invited to review evidence and modify statements using Delphi process and grading of recommendations assessment, development and evaluation system.

Background: Congenital insensitivity to pain (CIP) conditions are a group of Mendelian disorders with clinical and genetic heterogeneity. CIP with anhidrosis (CIPA) is a distinct subtype caused by biallelic variants in the NTRK1 gene.

Methods: In this study, six families with CIPA were recruited and submitted to a series of clinical and genetic examinations.

Article Synopsis
  • There is increasing interest in using transition-metal-free catalysts for capturing and reducing carbon monoxide (CO), and this study explores a method to do so using block-localized wave function (BLW) and density functional theory (DFT).
  • The research highlights that a combination of low valent aluminum compounds and alkaline earth metals can effectively capture CO through unique ionic metal-metal bonds, despite both metals being positively charged.
  • Additionally, the study identifies that the aluminum compound can activate CO by transferring an electron to it, forming a complex that is further enhanced by the presence of the alkaline earth metals.

Metal-stabilized radicals have been increasingly exploited in modern organic synthesis. Here, we theoretically designed a metalloradical complex Co-C˙Ph3 with the triplet characters through the transition metal cobalt (Co0) coordinating a triphenylmethyl radical. The potential catalytic role of this novel metalloradical in the CO2 reduction with H2/CH4 in the gas phase was explored via density functional theory (DFT) calculations.

The aims of this study were to investigate the effect of neuromuscular electrical stimulation (NMES) combined with strengthening exercise on movement in children with spastic cerebral palsy (CP). One hundred children with spastic CP were randomly divided into a treatment group (NMES and strengthening exercise, n = 50) and a control group (only NMES, n = 50). We compared the Comprehensive Spasticity Scale (CSS) score, Gross Motor Function Measure (GMFM) score, and walking speed before treatment and 6 weeks and 3 months after treatment between the 2 groups.
