Regulation of non-coding RNA in type H vessels angiogenesis of bone / 中国修复重建外科杂志

OBJECTIVE@#To summarize the regulatory effect of non-coding RNA (ncRNA) on type H vessels angiogenesis of bone.@*METHODS@#Recent domestic and foreign related literature about the regulation of ncRNA in type H vessels angiogenesis was widely reviewed and summarized.@*RESULTS@#Type H vessels is a special subtype of bone vessels with the ability to couple bone formation. At present, the research on ncRNA regulating type H vessels angiogenesis in bone diseases mainly focuses on microRNA, long ncRNA, and small interfering RNA, which can affect the expressions of hypoxia inducible factor 1α, platelet derived growth factor BB, slit guidance ligand 3, and other factors through their own unique ways of action, thus regulating type H vessels angiogenesis and participating in the occurrence and development of bone diseases.@*CONCLUSION@#At present, the mechanism of ncRNA regulating bone type H vessels angiogenesis has been preliminarily explored. With the deepening of research, ncRNA is expected to be a new target for the diagnosis and treatment of vascular related bone diseases.

Choice for the treatment of Monteggia′s fracture in children / 中国矫形外科杂志

[Objective]To discuss the clinical results and treatments of the Monteggia's fracture in children.[Method]Total of 66 patients including 61 fresh and 5 old fractures were reviewed.There were 47 males and 19 females.According to the Bado classification system: 46 of type Ⅰ,4 of type Ⅱ,15 of type Ⅲ,1 of type Ⅳ,all patients received conservative or operatire treatment.The conservatively treated patients received manipulation and plaster immobilization.In the operative group,the patients were fixed with single or/and double Kirschner's wires after reduction of the radiohumeral joints or/and fractured ulna.Neither reparation nor reconstruction was needed.[Result]All patients were available at the final follow up with 0.5～5 years.According to the Li Hanmin's scoring system for the motion function in children: excellent and good rate was 95.7% in conservative group and 84.2% in operative group.There was no complication such as myositis ossificans,synostosis of radius and ulna,ulna nonunion,radial head dislocation and profundus radial nerve injury.The cases of nerve injury were complete recovered after operation two or four months later.[Conclusion]The clinical results of the Monteggia's fracture in children was very good with immediate reduction and internal fixation in proper cases,a good overall therapeutic outcome can be expected in children with Monteggia's fracture.It is very important to prevent missed diagnosis.
