Cervical dumbbell tumor poses great difficulties for neurosurgical treatment and incurs remarkable local recurrence rate as the formidable problem for neurosurgery. However, as the routine preoperative evaluation scheme, MRI and CT failed to reveal the mutual three-dimensional relationships between tumor and adjacent structures. Here, we report the clinical application of MSCTA and VRT in three-dimensional reconstruction of cervical dumbbell tumors. From January 2012 to July 2014, 24 patients diagnosed with cervical dumbbell tumor were retrospectively analyzed. All patients enrolled were indicated for preoperative MSCTA/VRT image reconstruction to explore the three-dimensional stereoscopic anatomical relationships among neuroma, spinal cord and vertebral artery to achieve optimal surgical approach from multiple configurations and surgical practice. Three-dimensional mutual anatomical relationships among tumor, adjacent vessels and vertebrae were vividly reconstructed by MSCTA/VRT in all patients in accordance with intraoperative findings. Multiple configurations for optimal surgical approach contribute to total resection of tumor, minimal damage to vessels and nerves, and maximal maintenance of cervical spine stability. Preoperative MSCTA/VRT contributes to reconstruction of three-dimensional stereoscopic anatomical relationships between cervical dumbbell tumor and adjacent structures for optimal surgical approach by multiple configurations and reduction of intraoperative damages and postoperative complications.

Deregulated expression of miRNAs is related to progression and initiation of human cancers. Although miR-495 has identified in various tumors, its expression and function in renal cell carcinoma (RCC) is still unknown. In this study, we found that the expression of miR-495 was downregulated in RCC cell lines and tissues. Ectopic expression of miR-495 induced G0/G1 phase arrest and suppressed cell proliferation and migration in RCC cell lines. We further validated SATB1 was a direct target of miR-495 in RCC. In addition, re-expression of SATB1 reversed the miR-495-induced inhibition of cell proliferation and migration. These data suggest that miR-495 functions as a tumor suppressor and may be a promising therapeutic target in RCC in the future.
