Objective To explore the clinical characteristics and operative methods of the ankle fracture combined with Tillaux-Chaput and Volkmann fractures.Methods The data of 15 patients who were suffered the ankle fracture combined with the simultaneous fractures of Tillaux-Chaput and Volkmann between Septenber 2005 and January 2012 were analyzed.There were 8 males and 7 females with an average age of 27.3 years (range,16-57 years).All had medial malleolar and fibular fracture with Tillaux-Chaput and Volkmann tubercle avulsed fracture.X-ray film shows that there were 8 cases in which the patients had Tillaux-Chaput fracture,among whom 7 were diagnosed by CT scan.Classified by Lauge-Hansen system,ankle fracture could be divided into pronation-exterual rotation type in 4 cases,and pronation-abduction type in 11 cases.The fracture of fibula and the Volkmann tubercle were treated through the posterolateral approach.The fibular fracture was fixed with plate.The medial malleolar fracture was explored from medial curve approach.Tillaux-Chaput fracture was treated by the mierotubule cut.All patients were assessed with the ankle hindfoot clinical rating system of the American Orthopaedic Foot and Ankle Society (AOFAS).Results All patients were followed up for 8-20 months (average,12.5 months).The fracture healed 12-36 weeks later in all the 15 patients,with an average of 23.5 weeks.Twelve patients walked normally and 3 with mild claudication in the last follow-up.The AOFAS score was average 85.4 points,9 were excellent,4 were good,2were fair,with the good-excellent rate being 86.7％ (13/15).The movement of ankle joint limited in 3 patients,tenderness occurred when weight bearing in 3 patients.Conclusion The ankle fracture include the simultaneous fractures of Tillaux-Chaput and Volkmann were more seen in the type of pronation-abduction.It is often misdiagnosis by the photograph; CT scan should be helpful to find the fracture fragments.The exact reduction and stable fixation were needed in the treatment of the ankle fracture combined with Tillaux-Chaput and Volkmann fractures.Inferior tibia fibular screw was not routinely used in this fracture.

Objective To estimate the effect of open reduction and internal fixation for treating the trimalleolar fracture in the elderly.Methods 57 aged patients suffered from the trimalleolar fracture and were treated with internal fixation from January 2009 to June 2012.25 males and 32 females with an average age of 71.5 years ranged from 65 to 81 years were involved in this study.The supination-external rotation type were in 41 cases and pronation-external rotation type in 16 cases according to Lauge-hansen's classification.The posterior and lateral approach was taken for surgical procedure of lateral malleolar frature.The routine or locking plates were used to fix the fratures.The posterior malleolar fractures were usually fixed through the posterolateral approach as well.The screws or tension band fixation was selected for fixing the medial malleolar fragments.The parallel screwing fixation could be helpful for fixing the tibiofibular syndesmosis.Results The ankle function was evaluated by the criteria system of the American Orthopaedic Foot and Ankle Society (AOFAS).The efficacy was excellent in 23 patients,good in 24 patients,fair in 7 patients.The skin problems such as super facial infection and delayed union of incision were in 7 cases.Conclusions If choosing reasonable operation method and suitable internal plant,the open reduction and internal fixation has better effect in treating the trimalleolar fracture in the elderly,with fewer complications.

We discussed the function of four pairs of genes in the toxin-antitoxin system of Mycobacterium tuberculosis,providing theoretical foundation and scientific basis for studying the transmission mechanism of Mycobacterium tuberculosis.Four pairs of genes which belong to VapBC family,including four VapC genes (Rv1720c,Rv2103c,Rv2494,Rv3408) and four VapB genes (Rv1721c,Rv2104c,Rv2493,Rv3407) were chosen.We constructed a serial of arabinose-induced hybrid plasmid system in Escherichia coli and a serial of acetamide-induced hybrid plasmid system in Mycobacterium smegmatis respectively,in order to observe the potential inhibition effect of VapC and the release inhibition of homologous VapB.Results showed that only one toxin gene(Rv2103c) showed the function of bacteriostasis in both E.coli and M.smegmatis and the homologous antitoxin gene(Rv2104c) could release the inhibition of growth.We built the inducible systems of VapBC family in both E.coli and M.smegmatis respectively and found only a pair of toxin and antitoxin genes(Rv2103c,Rv2104c) had the function of inhibition and release for the growth of bacteria.And two pairs of toxin genes(Rv1720c,Rv2494) did not have the function of inhibition for the growth of both E.coli and M.smegmatis.Whereas,another toxin gene VapC47(Rv3408) also did not have the bacteriostastic activity,only this result was not consistent with the existing literature.We speculated that the reason for this kind of difference may be the different inducible systems we used.Cause the other three results were consistent with all existing literature and the doubtful result also appeared in other reports,so our protocol could be confirmed as reliable,and we would use it to build inducible systems and make further functional identification of certain toxin and antitoxin genes that we are interested in.
