Chinese Journal of Postgraduates of Medicine 2013;36(29):26-28
Objective To investigate the application value of minimally-invasive surgical treatment in patients with traumatic epidural hematoma(EDH)straddling transverse sinus.Methods Forty-eight patients with traumatic EDH straddling transverse sinus were chosen and preoperative Glasgow Coma Scale (GCS)score ≥8 scores were managed with minimally-invasive drainage under CT location.CT scanning was performed 1 h,3 d after operation and hematoma volume was calculated,and Glasgow Outcome Scale(GOS)score was evaluated 3 months after operation.Results CT scanning showed that the hematoma volume preoperative was(46 ± 14)ml,postoperative of 1 h was(21 ± 4)ml,and 3 d was(16 ± 3)ml,decreased more obviously than preoperative,and there was significant difference(P < 0.05).The GCS score preoperative was(8 ± 4)scores,postoperative of 3 d was(12 ± 2)scores,increased more obviously than preoperative,and there was significant difference(P < 0.05).Three months after operation in 48 patients,GOS score 5 points 37 cases(77.1%,37/48),4 points 7 cases(14.6%,7/48),2 points 2 cases(4.2%,2/48),1 point two cases(4.2%,2/48).Conclusion Minimally-invasive drainage is effective in the treatment of traumatic EDH straddling transverse sinus with GCS score ≥ 8 scores.
2.The evolution of multiple myeloma treatment strategies based on changes in effect judgment
Chinese Journal of Clinical Oncology 2014;(13):827-830
Basic research and clinical research on multiple myeloma (MM) have extensively progressed, as proven by the change in the definition of complete response (CR). With improvements in laboratory technology and introduction of novel agents, CR particu-larly emphasized both micro-and macro-models. The development of CR yielded therapeutic advances in MM and vice versa. The defi-nitions of response and treatment strategies were closely connected and improved. A need exists for further detailed studies on long-term disease control, such as optimal combination of agents. Given the shortage of new drugs and the distinctiveness of health in-surance, Chinese doctors should select the best treatment projects based on real-life situation in China.
