hsa-miR-9-5p Down-Regulates HK2 and Confers Radiosensitivity to Nasopharyngeal Carcinoma.

Background: This study was designed to explore the effects of hsa-miR-9-5p on radiotherapy sensitivity of nasopharyngeal carcinoma (NPC) by targeting hexokinase 2 (HK2).

Methods: The levels of hsa-miR-9-5 and HK2 in NPC patients and radiosensitive and resistant cells were determined using qRT-PCR. The dual luciferase reporter gene system was used to determine hsa-miR-9-5p targeting HK2.

[Clinical study about 18 cases with endoscopic surgery for nasal inverted papilloma].

Objective: To evaluate the method and value of the nose endoscopic surgery on thoroughly cutting the nose inverted papilloma.

Method: Eighteen patients with nasal inverted papilloma were treated by the nasal endoscopic surgery were analyzed retrospectively. Among all patients, the nasal inverted papilloma excision by endoscopy was in 14 cases, the nasal endoscopy uniting Caldwell-Luc surgery was in 4 cases.
