Confronted with similar problems and difficulties in mainland,Taiwan reformed its medical education. The reform included setting up flexible program,formulating objective and detailed rotary guide,making the best of the resources,implementing medical humanities education based on the reality and forming unique cultivation system and mode. These measures can be taken as references for medical education reform in mainland.

Objective To explore the role of sulodexide(SDX)in neointimal hyperplasia of arteriovenous fistulas(AVFs)in chronic kidney disease(CKD)rats and its possible mechanism.Methods A total of 18 male rats(weighing 300±50 g)were randomly and equally divided into AVF group,CKD+AVF group(CKD induction followed by AVF surgery and then gavaged with normal saline for 2 months),and CKD+AVF+SDX group[treated as in the CKD+AVF group but with 8 mg/(kg·d)SDX gavage].HE staining was used to observe the degree of neointimal hyperplasia.The expression of Hippo pathway related molecules,Yes-associated protein(YAP),pYAP and connective tissue growth factor(CTGF,YAP downstream target protein,one of mesenchymal marker)was detected by immunofluorescence assay.After human umbilical vein cell fusion EAHy926 cells were treated with 0,2.5,5,10,20 or 40 μg/mL SDX for 24 h,and with 2.5 μg/mL SDXfor24,48 or 72 h,respectively,CCK-8 assay was used to measure cell survival rate.Moreover,the serum sample from CKD rat was used to treat EAHy926 cells,and then the cells were treated with SDX or YAP inhibitor verteporfin.The expression levels of YAP,pYAP,CTGF and endothelial cell marker CD31 were detected by Western blotting.Results HE staining and immunofluorescence assay showed that CKD rats had serious neointimal hyperplasia in AVFs(P＜0.05),and slightly lower expression of pYAP and enhanced expression of CTGF(P＜0.05)when compared with the rats of the AVF group.While,SDX treatment alleviated the neointimal hyperplasia of AVFs,enhanced the expression of pYAP and reduced the expression of CTGF(P＜0.05).CCK-8 assay showed that cell survival rate was decreased significantly in a dose-and time-dependent manner after SDX treatment(P＜0.05).Western blotting revealed that SDX increased the expression of pYAP and CD31 while inhibited the expression of CTGF in EAHy926 cells(P＜0.05),which was consistent with the effect of verteporfin treatment.Conclusion SDX can block YAP activation caused by CKD and attenuate neointimal hyperplasia in AVFs.

Objective To analyze kinematic characteristics of children with spastic cerebral palsy during walking based on the method of gait analysis. Methods The gait of 14 children with spastic cerebral palsy and 16 healthy children, who were required to walk back and forth on level ground at normal speed, was tested using portable gait analyzer. The gait differences between diseased side and healthy side of lower limbs for children with spastic cerebral palsy, as well as the gait differences between children with spastic cerebral palsy children and healthy children were compared. Results For children with spastic cerebral palsy, single step time, swing time and toe-off time of diseased side were significantly longer than those of healthy side (P＜0.05), while step frequency, velocity and terminal stance were significantly shorter than those of healthy side (P＜0.05). Compared with healthy children, gait cycle time, single step time, stance time, swing time, percentage of stance phase, mid stance phase, pre-swing stage and toe-off time for diseased side of children with spastic cerebral palsy were significantly longer (P＜0.05). Stride, velocity, step frequency and terminal stance of the children with spastic cerebral palsy were significantly lower than those of healthy children (P＜0.05). Pulling acceleration for children with spastic cerebral palsy also decreased compared with healthy children (P=0.05). Conclusions The stability of children with spastic cerebral palsy decreased during walking, and their single step time, swing time, toe-off time and pulling acceleration might be considered as the sensitive indicators.
