摘  要:目的:观察银杏叶提取物对老年肝癌切除术患者血浆S100β蛋白和炎性因子白细胞介素1β( IL-1β)、IL-6、肿瘤坏死因子α( TNF-α)及术后认知功能的影响。方法择期行肝癌切除术的老年患者60例,随机数字表法平均分为银杏叶组和对照组,各30例。银杏叶组术前1 h静脉滴注银杏叶提取物注射液25 ml,对照组输注等量0.9%氯化钠注射液。于给药前1 h (T1)、手术开始后2 h(T2)、术后6 h(T3)、24 h( T4)分别抽取颈内静脉血测定血浆S100β蛋白及IL-1β、IL-6、TNF-α浓度;应用简易智力状态量表( MMSE)于术前1 d、术后1、3、7 d 对患者进行认知功能评分,判定是否发生术后认知功能障碍。结果 T2~T4时2组血浆S100β及IL-1β、IL-6、TNF-α浓度较T1均升高(P<0.05);银杏叶组T3、T4时的S100β蛋白浓度明显低于对照组[(0.98±0.17)μg/L 比(1.65±0.14)μg/L,(0.70±0.29)μg/L 比(1.05±0.12)μg/L](P<0.05),IL-1β、IL-6及TNF-α浓度均明显低于对照组[IL-1β:(15.7±1.6)pg/L比(21.6±2.3)pg/L,(14.3±1.2)pg/L 比(19.2±2.3)pg/L,IL-6:(81±5)pg/L比(114±6)pg/L,(76±6)pg/L比(100±4)pg/L, TNF-α:(86±5)pg/L比(102±6)pg/L,(78±6)pg/L比(91±3)pg/L](均P<0.05);通过MMSE测定,银杏叶组4例(13.3%)、对照组7例(23.3%)发生术后认知功能障碍,2组比较差异有统计学意义(P<0.05)。结论银杏叶提取物可能通过抑制中枢性炎症反应而减轻脑细胞损伤,降低老年患者术后认知功能障碍的发生率。Objective To observe the effects of Ginkgo biloba extract ( EGB ) on plasma inflammatory mediators,S100βprotein and postoperative cognitive function in elderly patients undergoing liver cancer resection . Methods Sixty patients were equally randomized into EGB group and control group .EGB (25 mg) was infused before operation.Changes of plasma S100βprotein, interleukin-1β(IL-1β), interleukin-6 (IL-6) and tumor necrosis factor alpha ( TNF-α) were measured by the enzyme linked immunosorbent assay ( ELISA) before opera-tion ( T1 ) , 2 hours ( T2 ) , 6 hours ( T3 ) and 24 hours ( T4 ) after operation .Scores were recorded 1 day before the operation, 1, 3, 7 days after operation to investigate the incidence of postoperative cognitive dysfunction (POCD).Results The concentrations of plasma S100βprotein,IL-1β, IL-6, TNF-αat T2-T4 were higher than those at T1(P〈0.05).S100βprotein concentration in EGB group at T 3 and T4 were significantly lower than those in the control group[(0.98 ±0.17)μg/L vs (1.65 ±0.14)μg/L, (0.70 ±0.29)μg/L vs (1.05 ±0.12)μg/L] ( P 〈0 .05 ); IL-1β, IL-6 and TNF-αconcentrations were all significantly lower than those in control group [IL-1β:(15.7 ±1.6)pg/L vs (21.6 ±2.3)pg/L,(14.3 ±1.2)pg/L vs (19.2 ±2.3)pg/L, IL-6:(81 ±5)pg/L vs (114 ±6)pg/L, (76 ±6)pg/L vs (100 ±4)pg/L, TNF-α:(86 ±5)pg/L vs (102 ±6)pg/L, (78 ±6) pg/L vs (91 ±3)pg/L] (all P〈0.05).The incidence of POCD in control group (23.3%, 7 patients) was significantly higher than that in EGB group (13.3%, 4 patients) (P〈0.05).Conclusion EGB can attenuate the release of inflammatory mediators and S100βprotein after operation which can decrease the incidence of POCD in elderly people .
