[Objective] To determine the efficacy of one-stage posterior deformity correction with transpedicular screw system and anterior radical debridement following reconstuction with titanium mesh cage for treatment of lumbar tuberculosis. [Methods]Forty-three patients with lumbar tuberculosis were treated operatively through anterior and posterior combined approach.The postoperative neurologic status (ASIA,2000),graft fusion,deformity correction and complications were observed and analyzed respectively.[Results]Forty-one patients were followed up for a duration of 24~36 months (mean 28.3 months).A solid fusion was achived in all cases.The neurologic function was improved in all patients in different grades.The mean kyphotic angle was corrected by 21.3 degrees,the angle loss was 1?~3?,the mean vertebral height was restored by 10.2 mm,the mean height loss was 2.4 mm.There was no recurrence of the tuberculosis infection.[Conclusion]One-stage posterior deformity correction with transpedicular screw system and anterior radical debridement following reconstuction with titanium mesh cage is a safe and effective method in the surgical management of lumbar tuberculosis.

OBJECTIVE: To investigate the expression and significance of miRNA-324-3p and its target gene WNT2B in tissue specimens of nasopharyngeal carcinoma (NPC) specimens. METHOD: qRT-PCR was used to detect the expression of miRNA-324-3p and WNT2B mRNA, and Western blot was applied to assay the expression of WNT2B protein in 39 cases of NPC specimens and 21 cases of non-carcinoma epithelium. The relationship between their expression levels and clinicopathological characteristics and their correlation with clinical pathological parameters was analyzed. RESULT: The expression of miRNA-324-3p was significantly down-regulated decreased but WNT2B mRNA/protein increased obviously in NPC specimens (P < 0.01). A negative correlation between miRNA-324-3p and WNT2B was spotted (P < 0.05). The expression levels of these markers were closely correlated with T stage, clinic stage and cervical lymph node metastasis (P < 0.05). CONCLUSION The loss of miRNA-324-3p and ectopic WNT2B might co-induce the initiation and progression of NPC.
