  • Oculo-facio-cardio-dental syndrome caused by the BCOR gene: a systematic review

    Objective To systematically review the clinical presentations and gene types of oculo-facio-cardio-dental (OFCD) syndrome and to provide a theoretical basis for future diagnosis, prevention, and treatment of the disease. Methods The PubMed, EMbase, The Cochrane Library, Web of Science, CBM, WanFang Data, and CNKI databases were electronically searched to collect studies on OFCD syndrome published from inception to March 1st, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. A systematic review was then performed. Results A total of 19 studies involving 83 patients with OFCD syndrome were included. The patients had an average age of 15.95±16.03 years, including 5 males and 78 females. The clinical presentations mainly included ocular disorders, facial abnormalities, cardiac disorders, dental abnormalities, physical anomalies, and dysfunctions of other body systems. BCOR gene mutations were detected in 71 patients with OFCD syndrome (overall detection rate: 86%, 95%CI 78% to 93%), of whom five were males (detection rate: 6%, 95%CI 1% to 11%) and 66 were females (detection rate: 80%, 95%CI 71% to 88%). Patients were mostly treated using multidisciplinary symptomatic treatment approaches based on clinical presentations and imaging findings. Conclusion In addition to the typical clinical presentations, BCOR gene testing results should also be taken into consideration for the differential diagnosis of OFCD syndrome. Although symptomatic therapies in clinical practice are relatively mature, they do not address the underlying cause of the disease, i.e., BCOR gene mutations. In future research, greater attention should be diverted to gene therapy.

  • EXPERIMENTAL STUDY ON CONSTRUCTION OF NEUROTIZATION TISSUE ENGINEERED BONE FOR REPAIRING LARGE BONE DEFECTS IN RABBIT

    Objective Construction of viable tissue engineered bone is one of the most important research fields in the cl inical appl ication of bone tissue engineering, to investigate the function of nerve factors in bone tissue engineering by celldetection in vitro and construction of neurotization tissue engineered bone in vivo. Methods Fifty-four healthy New Zealandwhite rabbits, male or female, weighing 2-3 kg, were involved in this study. Bone marrow mesenchymal stem cells (BMSCs) from the bone marrow of white rabbits were cultured. The second passage of BMSCs were treated with sensory nerve or motor nerve homogenates, using the LG-DMEM complete medium as control. The prol iferation and osteogenic differentiation of the cells were observed and tested by the MTT assay, alkal ine phosphatase (ALP) stain, and collagen type I immunocytochemistry identification. The osteogenic induced BMSCs were inoculated in β tricalcium phosphate (β-TCP) biomaterial scaffold and cultured for 72 hours, then the β-TCP loaded with seed cells was implanted in the rabbit femur with 15 mm bone and periosteum defects. Fifty-four New Zealand white rabbits were randomly divided into three groups (n=18): sensory nerve bundle (group A) or motor nerve bundle (group B) were transplanted into the side groove of β-TCP scaffold, group C was used as a control without nerve bundle transplantation. X-ray detection was performed at the 4th, 8th, and 12th weeks after operation.
