RESUMEN
Objective To evaluate the surgical efficacy of tibial plateau osteotomy for treatment of old tibial plateau fracture.Methods From March 2007 to March 2018,18 old tibial plateau fractures were treated by tibial plateau osteotomy at the Department of Orthopedics,Central Hospital of Jilin City.They were 12 males and 6 females with a mean age of 41.2 years (from 19 to 60 years).The fracture healing time,healing rate and the Hospital for Special Surgery (HSS) score for knee function at the last follow-up were recorded.Results This series were followed up for an average of 24 months (from 12 to 36 months).Of them,17 obtained clinical healing,giving a healing rate of 94.4％.The healing time ranged from 4 to 16months (average,10 months).By the HSS score at the last follow-up,11 cases were rated as excellent,4 as good,2 as fair and one as poor.Conclusion Tibial plateau osteotomy is an effective treatment for old tibial plateau fractures.
RESUMEN
OBJECTIVE@#To investigate the effect of yizhi jiannao granule concentration fluid (YCF) on the expression of peptidyl-prolyl-cis-trans isomerase A (Pin1) and high mobility group box 1 (HMGB1) mRNA in the hippocampus of senescence accelerated mice Senile-Prone8(SAMP8).@*METHODS@#Six-month old SAMP8 mice were randomly divided into a YCF group and a model group. Six-month old SAMP8 mice were served as a normal control group. The YCF group was ravaged, while the model group and the normal control group were gavaged with double-distilled water for 8 weeks. The hippocampus was taken out for examination. The expression of Pin1 and HMGB1 mRNA was measured by RT-PCR.@*RESULTS@#In the YCF group, the level of Pin1 mRNA increased, and the level of HMGB1 mRNA decreased compared with that of the model group.@*CONCLUSION@#Yizhi jiannao granules can prevent Alzheimer's disease by increasing the Pin1 level and decreasing the HMGB1 level.
