Chinese Journal of Orthopaedic Trauma 2012;14(11):945-949
Objective To observe the clinical outcomes of modified posteromedial and posterolateral approaches for the treatment of posterior tibial plateau fractures.Methods Between January 2006 and October 2011,25 patients with posterior tibial plateau fracture were identified.They were 17 men and 8 women,aged from 22 to 76 years (average,46.4 years).According to the AO/OTA classification,there were 4 cases of type 41-B1,6 cases of type 41-B2 and 15 cases of type 41-B3.According to Luo's three-column classification,they were all posterior column fractures.Ten patients with posterolateral tibial plateau fracture were treated by the modified posterolateral approach and the other 15 patients with posteromedial tibial plateau fracture by the modified posteromedial approach.The posterior fractures were fixated with a buttress plate.The knee function was evaluated at the last follow-up by the The Hospital for Special Surgery (HSS) Score.Results All the 25 cases were followed up for a mean time of 13.2 months (from 10 to 24 months).By the radiological Rasmussen criteria for fracture reduction,the mean score immediately after surgery was 16.5 points (from 13 to 18 points),with 20 excellent cases,4 good cases and one fair case.All patients were pain-free with full range of motion.Radiologically,bone union was achieved in all cases after a mean time of 13.9 weeks (from 12 to 18 weeks).No surgery-related complications were found.The mean HSS score was 91 points(range,74 to 97 points) and the good to excellent rate was 100% (17 excellent and 8 good cases) at the last follow-up.The average range of knee motion ranged from 0° to 125°.Conclusion In the treatment of posterior tibial plateau fractures,because the modified posteromedial and posterolateral approaches can result in excellent fracture reduction under direct visualization and allow for posterior buttress plating,soft tissues can be well preserved and good functional results can be expected.
9.Expression of Cdx2 and LI-cadherin in intestinal metaplasla of gastric mucosa and gastric adenocarcinoma of the intestinal type
Chinese Journal of Digestive Endoscopy 2009;26(7):360-363
Objective To explore the expression of caudal type homeobox transcription factor 2 (Cdx2) and liver intestinal cadherin (LI-CD) in intestinal metaplasia ( IM ) of gastric mucosa and gastric adenocarcinoma of the intestinal type (GAIT). Methods By using immunohistochemical method, the ex-pressions of Cdx2 and LI-CD were detected in biopsy sample including 30 cases of GAIT, 30 IM and 30 nor-mal controls. Results The positive rate of Cdx2 expression was 0, 93.3% and 46.7% in normal stomach mucosa, IM and GAIT, respectively. The positive rates of Cdx2 expression in IM and GAIT were significant-ly higher than that in normal stomach mucosa ( P < 0. 005 ), and the expression of Cdx2 in IM was signifi-cantly higher than that in GAIT (P<0. 005). Similarly, LI-CD was also negative in normal stomach muco-sa, and positive rates were 96. 7% and 73. 3% in IM and GAIT group, which were significantly higher than that in normal stomach mucasa (P < 0. 005 ), and LI-CD expression was also significantly higher in IM than in GAIT (P < 0. 05 ). In addition, the staining intensity of Cdx2 and LI-CD expressions in IM exhibited sig-nificant correlation (r=0. 827, P<0.01), but those in GAIT did not (r =0.438, P=0. 117). Conclu-sion Ectopic expression of Cdx2 and LI-CD can be found in IM and GAIT tissues, which could be an early marker in the disease progression. There is correlation between Cdx2 and LI-CD expression in IM tissue of human, and presumably, Cdx2 regulates LI-CD in IM development.
