摘 要: 觀察補益中藥對運動性腎缺血再灌注損傷大鼠腎臟炎癥因子及 ECM 表達的影響。方法:75 只 7 周齡雄性Wistar 大鼠隨機分為 4 組:安靜對照組( C 組,12 只) 、一般訓(xùn)練組( M 組,12 只) 、過度訓(xùn)練組( OM 組,24 只) 和補益中藥 + 過度訓(xùn)練組( TM 組,24 只) ,M、OM、TM 組進行 8 周 56 天的游泳訓(xùn)練。采用專業(yè)灌胃器每天灌胃 1 次,TM 組灌胃采用黃芪、紅景天、丹參、苦參等組成的復(fù)合中藥制劑,劑量為 1 g·kg - 1 ,體積為 5 mL·kg - 1 ,其他各組灌胃等量生理鹽水。末次訓(xùn)練后 24 h,采用 PAS 染色觀察腎小球 ECM 沉積情況,免疫組織化學(xué)法檢測腎組織 TNF-α、IL- 1β、IL-6、IL-18 蛋白表達,RT-PCR 法檢測腎組織 TNF-α mRNA、IL-1β mRNA、IL-6 mRNA、IL-18 mRNA、TGF-β1 mRNA表達。結(jié)果:1)8 周實驗后,腎小球 ECM 沉積,C、M 組間無顯著差異( P > 0. 05 );OM 組較 C、M 組顯著增加( P <
0. 01);TM 組顯著低于 OM 組( P < 0. 05)。2) 血尿素氮和血清肌酐水平,OM 組和 TM 組顯著高于 C 組( P < 0. 01), TM 組顯著低于 OM 組( P < 0. 05);腎組織 TNF-α、IL-1β、IL-6 和 IL-18 蛋白表達,OM 組和 TM 組顯著高于 C 組( P <
0. 01) ,TM 組顯著低于 OM 組( P < 0. 05);腎組織 TNF-α mRNA、IL-1β mRNA、IL-6 mRNA 和 IL-18 mRNA 表達,OM、 TM 組顯著高于 C 組( P < 0. 01) ,TM 組顯著低于 OM 組( P < 0. 05);腎組織 TGF-β1mRNA 表達,TM 組( P < 0. 05) 和 OM 組( P < 0. 01) 顯著高于C 組,TM 組顯著低于OM 組( P < 0. 05)。結(jié)論:8 周過度訓(xùn)練致大鼠發(fā)生運動性腎缺血再灌注,同時 ECM 沉積加強。補充補益中藥可通過抑制腎臟組織 TNF-α、IL-1β、IL-6、IL-18 的表達進而減輕了過度訓(xùn)練誘導(dǎo)腎臟缺血再灌注發(fā)生時腎臟組織 TGF-β1 的表達,抑制 ECM 的合成和( 或) 促進 ECM 的降解及組織病理學(xué)改變,延緩或避免過度訓(xùn)練導(dǎo)致的運動性缺血再灌注對腎臟的損害。

Abstract:Objective:To study the protective effects of tonic medicine on kidney inflammation factors and extracellular ma- trix ( ECM ) expression in rats of exercise-related renal ischemia-reperfusion injuries. Methods:75 male Wistar rats at the age of 7 weeks were divided into 4 groups randomly:control group( C group,n = 12) ,general training group( M group,n =
12) ,overtraining group( OM group,n = 24) ,tonic medicine + overtraining group( TM group,n = 24) ,the Rats in M , OM ,TM groups were assigned to 8 weeks of swimming training,7 days a week. Professional gavage were given once a day. The Rats of TM group were given with compound Chinese herbal medicine( The primary elements were Chinese drugs for invigoration,such as Astragalus,Rhodiola rosea,Salviae miltiorrhizae,Sophora flavescens) ,gavages( ig) dose was 1 g
· kg - 1 ;ig volume was 5 mL·kg - 1 ,and other groups were given the normal saline. 24 hours after the last training,w e ob-
served the glomerular ECM deposition by the PAS stain;detected the renal tissue of TNF-α,IL-1β,IL-6,IL-18 protein by immunohistochemistry and detected the expression of TNF-α mRNA,IL-1β mRNA,IL-6 mRNA,IL-18 mRNA,TGF-β1 mRNA gene in renal tissue by RT-PCR method. Results:1)8 weeks after the experiment,the glomerular ECM deposition of C group and M group appeared normal and showed no differences( P > 0. 05);OM group was significantly higher than that in C group and M group( P < 0. 01) ,TM group was significantly lower than that of group OM ( P < 0. 05). 2) OM

group and TM group blood urea nitrogen and serum creatinine were significantly higher than that of C group( P < 0. 01), TM group was significantly lower than that of group OM ( P < 0. 05);the expression of renal TNF-α,IL-1 β,IL-6 and IL- 18 protein in OM group and TM group was significantly higher than that in C group( P < 0. 01) ,TM group was significant- ly lower than that of group OM ( P < 0. 05);the expression of renal TNF- α mRNA,IL-1 β mRNA,IL-6 and IL-18 mRNA in TM group and OM group was significantly higher than that of C group( P < 0. 01) ,TM group was lower than of OM group( P < 0. 05);the expression of renal TGF-β1mRNA in TM group and OM group was significantly higher than that of C group( TM ,P < 0. 05;OM ,P < 0. 01) ,TM group was significantly lower than of OM group( P < 0. 05). Conclusion: 8 weeks overtraining caused the movement of rat renal ischemia reperfusion and increased the deposition of ECM . Tonic medicine can restrain the expression of renal tissue TGF-β1 during exercise-related renal ischemia-reperfusion injury in- duced by overtraining,w hich may be achieved by inhibiting the expression of IL-1,TNF-α,IL-6,IL-18 in renal tissue. Fi- nally it decreased the synthetic and increased the decomposition of ECM ,reduced the damage and the histopathological changes,as a result,Tonic medicine can protect the rats from exercise-related renal ischemia-reperfusion injury.
