Neck dissection of cN0 maxillary oral squamous cell carcinoma: A study based on SEER database.

Objective: For patients with clinical nodal-negative (cN0) maxillary oral squamous cell carcinoma (MOSCC), neck dissection (ND) and clinical observation are the main two management strategies for the neck. However, the indications corresponding to these two options remain controversial. This study aimed to elucidate the clinical factors affecting ND treatment and to identify clinical characteristics of the population that may benefit from ND based on a retrospective analysis of cN0 MOSCC patient data from the Surveillance, Epidemiology, and End Results (SEER) database.

[Dose-response Relationship of Dexmedetomidine Combined with Sufentail for Postoperative Intravenous Analgesia in Video-assisted Thoracoscopic Surgery].

Objective To investigate the 50% effective dose(ED)and 95% effective dose(ED)of dexmedetomidine(DEX)combined with 0.032 μg/(kg·h)sufentanil as well as its analgesic effect for patient-controlled intravenous analgesia(PCIA)after video-assisted thoracoscopic surgery(VATS).Methods Totally 25 patients undergoing elective VATS were enrolled.

Systematic analysis of genes involved in oral cancer metastasis to lymph nodes.

Oral cancer remains a deadly disease worldwide. Lymph node metastasis and invasion is one of the causes of death from oral cancer. Elucidating the mechanism of oral cancer lymph node metastasis and identifying critical regulatory genes are important for the treatment of this disease.

Propofol-sparing effect of different concentrations of dexmedetomidine : Comparison of gender differences.

Background: The pharmacodynamics of propofol are closely linked to gender. Dexmedetomidine can decrease propofol needs during propofol anesthesia. The aim of this study was to compare the gender differences on the calculated effect site median effective concentration (EC) of propofol for loss of consciousness (LOC) after pretreatment with different concentrations of dexmedetomidine.
