  • Relation Between BRAFV600E Mutation and Thyroglobulin or Clinicopathologic Characteristics of Papillary Thyroid Carcinoma

    ObjectiveTo discuss the correlation of BRAFV600E mutation with clinicopathologic characteristics or thyroglobulin (Tg) in papillary thyroid carcinoma (PTC) and its clinical significance. MethodsThe BRAFV600E mutations of 55 patients with PTC were detected by nested PCR. The relations between BRAFV600E mutation and the clinicopathologic characteristics were analyzed. Results①The BRAFV600E mutations happened in 29 patients with PTC, the mutation rate was 52.7% (29/55).②The BRAFV600E mutation rate was related with extracapsular spread, multiple lesions, regional lymph node metastasis or average Tg value > 1.0μg/L during 2 years after standardized treatment (P value was 0.01, 0.02, 0.02, 0.03, respectively), but which not related with the gender, age, tumor diameter, or TNM stage (P > 0.05). ConclusionThe BRAFV600E mutation in PTC might lead to increased tumor aggressiveness and it might be related with increased Tg value after standardized treatment.

  • Kirschner WIRE FIXATION IN THREE JOINTS COMBINED WITH BONE ANCHOR REPAIR FOR TREATMENT OF ACUTE PERILUNATE INJURY

    ObjectiveTo investigate the effectiveness of Kirschner wire fixation in scapholunate joint, capitolunate joint, and lunotriquetral joint combined with bone anchor repair for the treatment of acute perilunate injury. MethodsBetween January 2007 and January 2012, 35 cases of acute perilunate injury were treated. There were 30 males and 5 females with an average age of 45.5 years (range, 32-56 years). Fractures were caused by falling from height in 18 cases, by traffic accident in 11 cases, and by fall injury in 4 cases. The time from injury to operation was 2-6 days (mean, 3.4 days). There were 23 cases of trans-scaphoid perilunate dislocation, 10 cases of perilunate dislocation, and 2 cases of trans-triangular perilunate dislocation. Associated injuries included median nerve injury in 6 cases, radius styloid fracture in 8 cases, ulnar styloid fracture in 2 cases, and distal tibial fracture in 1 case. All the patients were treated by open reduction, Herbert screw fixation of scaphoid fractures, and Kirschner wire fixation in scapholunate joint, capitolunate joint, and lunotriquetral joint, and the intercarpal ligaments were repaired by Mitek bone anchor. ResultsSuperficial wound infection occurred in 2 cases, and primary healing of incision obtained in others. Thirty-five patients were followed up 12-35 months (mean, 18 months). X-ray films showed fracture union in 21 cases of scaphoid fractures, and bone nonunion in 2 cases of scaphoid fractures. During the follow-up period, there was no avascular necrosis of scaphoid or lunate. At last follow-up, the scapholunate angle, radiolunate angle, and wrist range of motion (ROM) in extension had no significant difference between affected and unaffected sides (P > 0.05). The wrist ROM in flexion and grip strength of affected side were not up to the levels of unaffected side (P < 0.05). According to the modified Mayo wrist scoring system, the score was 79.9±10.7, which were excellent in 8 cases, good in 17 cases, fair in 7 cases, and poor in 3 cases, and the excellent and good rate was 71.4%. The disability of arm-shoulder-hand (DASH) questionnaires score was 21±10. Traumatic osteoarthritis was observed in 2 cases. ConclusionKirschner wire fixation in scapholunate joint, capitolunate joint, and lunotriquetral joint combined with bone anchor repair for the treatment of acute perilunate injury can get early stability of the carpal joint, favorable intercarpal ligament repair, and good recovery of wrist joint function.
