Plain English summary of protocol

Background and study aims
Some broken bones do not heal even when they get the best surgical or nonsurgical treatment. In some cases, certain risk factors make it more likely that a bone will fail to heal. When a broken bone fails to heal it is called a "nonunion." Incomplete fracture healing may lead to chronic nonunion, thus determining fracture healing is the basic issue in clinical treatment. However, there are no validated molecules in the blood (biomarkers) for p chronic nonunion. In this study, bioinformatics analysis combined with the experimental verification strategy was used to identify blood biomarkers for chronic nonunion.

Who can participate?
Patients diagnosed with open fractures of long bone and defined non-union.

What does the study involve?
Participants will provide a single blood sample for analysis.

What are the possible benefits and risks of participating?

Scientific titleBioinformatic analysis and experimental identification of blood biomarkers for chronic nonunion
Study objectivesIncomplete fracture healing may lead to chronic nonunion, thus determining fracture healing is the basic issue in clinical treatment. However, there were no validated early diagnose biomarkers for assessing chronic nonunion. In this study, bioinformatics analysis combined with the experimental verification strategy was used to identify blood biomarkers for chronic nonunion.
Ethics approval(s)Approved 13/07/2018, Ethics Committee of Xuanwu Hospital, Capital Medical University (Chuangchun Street No.45, Beijing, China, 100053; +86-010-8319-9270; xwkyethics@163.com), ref: XW-2018-135.
Health condition(s) or problem(s) studiedNonunion of open fractures of long bone
InterventionPatients admitted to the Department of Orthopedics of Xuanwu Hospital between August 2018 and July 2019, are enrolled in this study. The group is categorized into the Healed and Nonunion groups, according to the FDA diagnostic criteria amendment. The FDA defines nonunion as a fractured bone that has not completely healed within 9 months following injury and without signs of healing for at least 3 months.
In this study, 9 months was chosen as the time point to define the nonunion.

Bioinformatics analysis combined with the experimental verification strategy was used to identify blood biomarkers for chronic nonunion. First, chronic nonunion differential expressed genes were identified by microarray data analysis. Second, Dipsaci Radix (DR), traditional Chinese medicine for fracture treatment, was used to screen the target genes. Third, the drug-compound-target-disease network was determined, and the biomarker genes were obtained. Finally, the potential blood biomarkers were verified by ELISA and qPCR methods.
