Objective To investigate the mRNA and protein expression of GPX3 gene in non-small cell lung cancer (NSCLC) patients, and then discuss the clinical significance of GPX3 in NSCLC patients. Methods Reverse transcription-polymerase chain reaction (RT-PCR) and Western blot were used to detect the GPX3 mRNA and protein levels in NSCLC tissues and adjacent non-cancerous normal lung tissues from 60 patients undergoing surgical treatment. The correlation between the expression levels of GPX3 and clinicopathological features was analyzed. Results The relative expression value of GPX3 mRNA was higher in adjacent non-cancerous tissues than in non-small cell lung cancer tissue (P < 0.05). GPX3 mRNA expression was significantly correlated with TNM stage、differentiation and lymph node metastasis. The integral optical density value of GPX3 protein confirmed was lower in adjacent non-cancerous tissues than in non-small cell lung cancer tissues (P < 0.05). In additional, the expression of GPX3 was related to TNM stage and lymph node metastasis. Conclusion The expression of GPX3 gene may play an important role in the carcinogenesis and progression of NSCLC.

BACKGROUND:Craniotomy for severe traumatic brain injury is required to maintain the integrity of the dura mater. The artificial dura mater is now a common dural repair material, and looking for the ideal artificial dura mater is the exploring direction of neurosurgery.
OBJECTIVE:To explore the application of colagen sponge artificial dura in severe traumatic brain injury
METHODS:A retrospective analysis of 96 patients with severe head injury was performed, including 32 cases of the artificial dura with tightly suturing as the control group, and 64 cases of the artificial dura of colagen sponge without suturing as the experimental group. Operating time for hematoma clearance, blood loss, postoperative mechanical ventilation time, ICU monitoring time, the total number of hospitalized days as wel as time interval from hematoma clearance to cranioplasty, operative time for cranioplasty, blood loss, and Glasgow Coma Scale scores after dural damage and 6 months postoperatively in the two groups were measured.
RESULTS AND CONCLUSION:The same purpose was achieved in the two groups. The amount of bleeding during hematoma clearance, postoperative mechanical ventilation time, monitoring time in ICU, the total number of hospitalized days and Glasgow Coma Scale score of 6 months postoperatively showed no significant difference between the two groups (P> 0.05). But operative time for hematoma clearance and cranioplasty as wel as blood loss in the second operation were statisticaly significant between two groups (P< 0.05). The colagen sponge artificial dura in severe traumatic brain injury can fuly play a good role in reducing intracranial pressure, keeping brain functions, shortening operative time, and improving outcomes of patients, which has similar effects to tightly suturing the dura and creates favorable conditions for the folowing cranioplasty.
