Objective To evaluate the ability of inductive osteogenesis of allgraft demineralized bone containing basic fibroblast growth factor (bFGF/ALB) in repairing bone defect. Methods Thirty-two New Zealand white rabbits were randomly divided into four groups (groups A,B,C and D, n=8). A segmental bone defect of15 mm inlength was made on the bilateral radius respectively and the defects filled with ALB/bFGF in group A, with ALB in group B, with bFGF in group C and without any materials in group D serving as blank control. At 2, 4, 6 and 8 weeks after operation, all restored bones were evaluated by roentgenography, histological observation and Ca2+detection of osteotylus. Results The X-ray films showed that groups A and B had a little shadow of bone formation at 2 weeks, while groups C and D had transparent shadow; that group A had denser shadow and new bone formation at 4 weeks and 6 weeks, groups B and C had a little increase of shadow and group D had little shadow at fractured ends; and that group A had formation of bone bridge at 8 weeks, the new formed bone in fractured ends of group B closed with each other, the gap still existed in group C, and the defects filled with the soft tissue in group D. The Ca2+content of group A was higher than that of groups B, C and D at 4 weeks (Plt;0.05) and 8 weeks (Plt;0.01). The histological observaton showed that the degree of bone restoration of group A was superior to that of groups B, C and D. Conclusion bFGF/ALB is a good material to improve bone restoration.
Objective To evaluate and summarize the relevant evidence on follow-up management of non-pregnant adult with pulmonary embolism, and provide a reference for optimizing the follow-up plan of non-pregnant adult with pulmonary embolism. Methods Clinical decision-making, guidelines, societies/associations websites related to follow-up of pulmonary embolism, and databases were searched for literature on follow-up management of non-pregnant adult with pulmonary embolism. The retrieval time limit was from databases establishment to December 2023. The included literature was evaluated for quality and summarized to form evidence. Results A total of 13 articles were included, including 3 clinical decision-making articles, 5 guidelines, 1 systematic review, and 4 expert consensus articles, forming 26 best pieces of evidence, involving 8 aspects of follow-up personnel and methods, follow-up time, physical assessment, activity guidance, contraception guidance, filter management, medication guidance, and lifestyle guidance. Conclusions The follow-up management of non-pregnant adult with pulmonary embolism is very important. When medical staff apply relevant follow-up management evidence, they should fully evaluate the patients’ willingness and medical environment, make full use of existing resources, optimize follow-up management strategies, reduce the occurrence of complications, and improve patient prognosis.
