Objective To compare the clinical efficacy of plating versus non-plating following ulnar oblique osteotomy in the treatment of obsolete Monteggia fractures in children.Methods Clinical data of 33 patients were reviewed who had been treated for obsolete Monteggia fracture in our department from January 2001 to June 2011.They were 23 males and 10 females,aged from 4 to 13 years (average,8.1 years).According to the Bado classification,23 cases were type Ⅰ,4 type Ⅱ and 6 type Ⅲ.Ulnar oblique osteotomy was performed in all the 33 cases to extend the ulna lengthways,but their subsequent fixation was different.In the non-plating group (17 cases),after reduction of the radial head,a supplementary transfixation of the radius was performed with a Kirschner wire through the capitellum,and the excised ulna was free of fixation.In the plating group (16 cases),after transfixation of the radius with a Kirschner wire through the capitellum,plating was performed of the excised ulna.Both groups were immobilized in a plaster cast after surgery.The 2 groups were compared with respect to healing time for the ulnar osteotomy and the Mackay scoring for postoperative elbow function.The 2 groups were comparable with no significant difference in the general data (P > 0.05).Results Follow-ups for an average of 1.5 years (from 10 months to 3 years) revealed no incision infection and ulnar healing in all the patients.The average ulnar healing time for the non-plating group (7.2 ± 1.1 weeks) was significantly shorter than for the plating group (8.5 ± 1.8 weeks) (P < 0.05).In the non-plating group,l0 cases were rated as excellent,5 good and 2 poor; in the plating group,11 cases were rated as excellent,4 good and one poor.In either of the 2 groups,3 cases reported residual pain in elbow motion.The non-plating group reported one case of dislocation of the capitellum.Conclusion Non-plating after ulnar osteotomy may be used as a treatment of obsolete Monteggia fractures in children,because it has advantages of less invasion to the ulnar blood supply,shortened operation time and healing time.
Flanders interaction analysis system was used to investigate the characteristics of demonstrative skills in the course of pathology for higher vocational students and undergraduate students.The most frequent demonstration skills used for higher vocational students were indicative PowerPoint(36.21%),vivid pictures(7.99%) and amplified pictures(7.47%);while the less frequent demonstration skills were mapping the keywords on the blackboard(1.69%),paralleling the key points(1.75%) and demonstration with pictures(1.82%).The demonstration skills such as demonstration with pictures,contrasting pictures,paralleling the key points,problem-based learning,vivid pictures,highlighting keywords,writing keywords on the blackboard,case based study and demonstration with actual samples were more frequently used for higher vocational students than undergraduate students(P<0.05);while indicative PPT was less frequently used for higher vocational students(P<0.01).The teachers should choose proper demonstration skills based on the characteristics of higher vocational students.

Objective To study the relationship between serum fibroblast growth factor-23(FGF-23) and cardiovascular calcification in patients with end-stage renal disease(ESRD). Methods A total of 60 ESRD patients were included in this study,the calcification of their abdominal aortas and cardiac valves was qualitatively assessed by both lateral-position plain radiography of abdomen and echocardiography,and FGF-23 by enzyme-linked immunosorbent assay(ELISA).A routine laboratory test was done for detection of serum creatinine(Scr),calcium(Ca),phosphorus(P),alkaline phosphotase(ALP),total cholesterol(TC),hemoglobin(HB),and immunoreactive parathyroid hormone(iPTH) was detected by electrochemilluminescence method.Forty individuals who joined physical examination were served as controls. Results The levels of FGF-23 in ESRD patients were higher than that in the control,the difference was significant(t=7.50,P0.01).A correlation analysis indicated that serum FGF-23 level was positively correlated with Scr,P,iPTH and ALP(r=0.411-0.675,P0.01),and not correlated with serum Ca,TC,TG,and HB(r=-0.113——0.012,P0.05).Serum FGF-23 was higher in ESRD patients with cardiovascular calcification than those without(t=5.40,P0.01). Conclusion The rising of serum FGF-23 in ESRD patients is closely related with occurrence and development of cardiovascular calcification.
