RESUMEN
A clinical decision support system (CDSS) integrated with electronic health records helps physicians at the grassroots make patient-appropriate and evidence-based treatment decisions and improves the efficiency of diagnosis and treatment. Furthermore, using ontologies to build up the medical knowledge base and patient data for CDSS enhances the automation and transparency of the reasoning process of CDSS and helps generate interpretable and accurate treatment recommendations. Herein, we reviewed the relevant ontologies in the field of diabetes treatment and the progress and challenges concerning ontology-based CDSSs. Firstly, we elaborated on the current status and challenges of diabetes treatment in China, highlighting the urgent need to improve the efficiency and quality of medical services. Then, we presented background information about ontologies and gave an overview of the framework, methodology, and features of using ontologies to construct CDSS. After that, we reviewed the ontologies and instances of ontology-based CDSS in the field of diabetes treatment in China and abroad and summarized their construction methods and features. Last but not the least, we discussed the future prospects of the field, suggesting that integrating evidence-based medicine with ontologies to build a reliable clinical recommendation system should be the current focus of CDSS development.

CD40 is a costimulatory protein expressed on the surface of many different cells. It delivers signals regulating diverse cellular responses, including proliferation, differentiation, growth suppression, and cell death. In this study, we report a novel CD40 mutant (c.234C>A or p.H78Q) that is expressed in the U266 cell line and in freshly isolated tumor cells. Three-dimensional structural model and Scatchard analysis revealed that the mutated residue located in a region is important for binding to CD40L (CD154). Functional analysis indicated that the mutated CD40 was translocated to the CD40 signalosome and involved in CD40 signal transduction. In conclusion, the mutation in CD40 can lead to an alteration of function, including the change of antigen epitope and the binding affinity with CD40L.
