Objective This study investigates the relationship of serum irfflammatory cytokine levels with intracranial pressure (ICP) in patients with severe traumatic brain injury (TBI) after surgery.Methods A total of 32 cases with severe TBI and placement of ICP monitor were prospectively enrolled.Serum was collected before surgery and every 12 h after surgery.Cytokines levels of interleukin (IL)-1β,IL-8,and tumor necrosis factor (TNF)-α were analyzed and compared with outcome of patients.Hourly values of ICP were recorded.The degree of ICP above treatment threshold (20 mm Hg) were calculated every 12 h as pressure times time dose(PTD-ICP20),which was compared with serum cytokine levels before (Pre) and after (Post) the 12-hour time period using linear regression method.Results Serum IL-1β (P＜0.05),IL-8 (P＜0.01) and TNF-a (P＜0.01) levels elevated dramatically after severe TBI and were significantly associated with outcome of patients.Mean PTD-ICP20 was (42.9 ± 60.2)mm Hg/h and was correlated with increased Pre-IL-8 (r=0.554,P＜0.001),Pre-TNF-α (r=0.597,P＜0.001),Post-IL-8 (r=0.629,P＜0.001) and Post-TNF-α (r=0.538,P＜0.001) levels.Conclusion Serum IL-8 and TNF-α demonstrated the most promising candidate bio.rnarkers of impending ICP elevation in this study.These findings indicate a feasible way of monitoring patients with severe TBI.

Objective To compared the efficacy of hyaluronan combined with eperisone hy-drochloride or simple application of hyaluronan or eperisone hydrochloride in the treatment of pa-tients with knee osteoarthritis (OA).Methods 99 patients with knee OA were randomly divided into hyaluronan group,eperisone hydrochloride group and combined group (hyaluronan combined with eperisone hydrochloride),33 cases in each group.Efficacy was compared among 3 groups. Rsults 5 weeks after treatment,WOMAC score of combined group was significantly higher than hyaluronan group and eperisone hydrochloride group.The CTX-Ⅱ content of urine in combined group was significantly lower than the other two groups (P <0.05).Conclusion Combination of hyaluronan and eperisone hydrochloride can significantly improve the clinical symptoms of patients with knee OA,and its efficacy is obviously better than simple application of hyaluronan or eperisone hydrochloride.
