米诺环素辅助治疗侵袭性牙周炎对血清炎性因子的影响

目的：观察在常规治疗基础上局部辅助米诺环素软膏治疗对侵袭性牙周炎（AgP）患者血清C反应蛋白（CRP）、肿瘤坏死因子-α（TNF-α）和白细胞介素-17（IL-17）浓度的影响。方法将45例AgP患者按随机数字表法随机分成两组，治疗组23例，采取龈下刮治、根面平整加局部2％盐酸米诺环素软膏用药；对照组22例，为单纯龈下刮治、根面平整。另有45例健康体检者作正常组，对AgP患者治疗前、后血清CRP、TNF-α和IL-17水平进行实验室检测，并与正常组、对照组比较。结果正常组血清CRP、TNF-α和IL-17水平均较AgP患者治疗前、后低（P＜0．05）。治疗3个月后AgP患者血清CRP、TNF-α和IL-17浓度较治疗前明显下降（P＜0．05）。结论在常规治疗基础上局部辅助米诺环素软膏治疗AgP患者，疗效显著，能改善血清CRP、TNF-α和IL-17等炎性因子水平。

Effect of serum inflammatory cytokine by adjuvant minocycline ointment in the treatment of aggressive periodontitis

Objective To investigate the changes of serum C reactive protein(CRP) ,tumor necrosis factor alpha(TNF-alpha) and interleukin-17(IL-17) by minocycline ointment on the basis of conventional therapy in the treatment of aggressive periodontitis (AgP) .Methods All 45 cases of AgP patients were randomly divided into two groups ,23 cases in the therapeutic group ,were per-formed scaling and root planning plus local minocycline hydrochloride Ointment medication;22 cases in the control group ,were trea-ted by scaling and root planing only .All aggressive periodontitis patients were detected the serum CRP ,TNF-alpha and IL-17 levels before and after treatment ,and compared with normal controls .Results The serum levels of CRP ,TNF-αand IL-17 in normal hu-man were lower than those of AgP patients before and after treatment(P<0 .05) .After 3 months treatment ,the serum levels of CRP ,TNF-αand IL-17 in AgP patients were significantly lower than those before treatment(P<0 .05) .Conclusion The effect of minocycline on the basis of conventional therapy in the treatment of AgP patient is remarkable ,which can improve the serum level of CRP ,TNF-alpha and IL-17 .
