Diabetes & Metabolism Journal 2025;49(2):321-330
Background:
Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients.
Methods:
Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines.
Results:
Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher.
Conclusion
MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.

Objective This study aims to investigate the role of gap junction mediated by connexin 43(Cx43)in renal injury induced by periodontitis in rats.Methods Twelve SPF-grade Wistar male rats were divided into a control group and a periodontitis group by using a completely random number table method,with six rats in each group.The control group rats were not treated,while the periodontitis group rats were subjected to wire ligation of the neck of their bilateral maxillary first molars to construct a periodontitis model.After 8 weeks of modeling,the rats were examined for clinical indicators of the periodontium.micro-CT scanning of the maxilla reconstructed its 3D structure and analyzed the absorption of alveolar bone.Histopathological changes in periodontal and renal tissues were detected.MitoSOX red reagent was used to determine reactive oxygen species(ROS)content in renal tissues.A biochemical reagent kit was used to detect serum oxidative stress biomarkers.Real-time fluo-rescent quantitative-polymerase chain reaction(qRT-PCR)was employed to determine Cx43,nuclear factor kappa-B(NF-κB),interleukin(IL)-1β,IL-6,BCL2-Associated X(Bax),B-lymphomatoma-2 gene(Bcl-2),and Caspase-3 mRNA were determined.Western blot analysis was used to detect Cx43,NF-κB,IL-1β,Bax,Bcl-2 and Caspase-3 protein.Re-sults micro-CT 3D reconstruction showed significant bone resorption of the first molar alveolar bone in the periodonti-tis group rats and decreased height of the alveolar ridge.The distance from the enamel cementum boundary to the top of the alveolar ridge in the periodontitis group was significantly higher than that inthe control group.The histopathological results showed a large number of inflammatory cells that infiltrated the periodontal tissue of the periodontitis group,and the alveolar bone was significantly absorbed.Rats in the periodontitis group also exhibited mild thickening of the glomer-ular basement membrane,dilation of the Bowman's capsule,and destruction of the brush-like edge of the renal tubules in the renal tissue.The MitoSOX red staining results showed a significant increase in ROS content in the renal tissue of the periodontitis group.The biochemical test results showed that the levels of superoxide dismutase and glutathione in the serum of rats with periodontitis decreased,while that of malondialdehyde increased.The results of qRT-PCR and Western blot showed that the expression levels of Cx43,IL-1β,IL-6,Bax,Caspase-3 mRNA and Cx43,IL-1β,NF-κB,Bax,Caspase-3 proteins in the periodontitis group significantly increased compared with those in the control group,while the expression levels of Bcl-2 mRNA and protein decreased.Conclusion Periodontitis may activate NF-κB sig-naling molecules by upregulating the expression of Cx43 in rat kidney tissues,leading to increased levels of inflamma-tion and apoptosis and ultimately inducing kidney injury.

Objective:To explore the psychological experience and demand of parents of children with delayed recovery after congenital heart disease surgery.Methods:This study adopted phenomenological research methods from qualitative research. Using the purposive sampling method, parents of postoperative delayed recovery children with congenital heart disease who met the inclusion criteria were selected as the research objects from October to November 2019 at Fuwai Hospital, Chinese Academy of Medical Sciences. Semi-structured interviews were conducted with the parents of the children, and the data were analyzed by Colaizzi 7-step analysis method.Results:Finally, 13 parents of children with delayed recovery after congenital heart disease surgery were included. According to the interview results, four themes were extracted, which were negative psychological experience of parents of children with delayed recovery, positive psychological experience and expectation change of parents, heavy economic burden of parents and diversified needs of parents.Conclusions:During the delayed recovery period, psychological experience of parents is complex and their needs are diverse. The nursing staff should identify and pay attention to the causes of the negative psychological experience of the parents of the children, timely channel their negative emotions and strengthen the positive psychological experience in many aspects. They can assist parents to seek social help to reduce physical and mental pressure and meet the diverse needs of parents by providing high-quality nursing services and multi-channel information support.
