摘要:
目的:探討信號傳導及轉(zhuǎn)錄激活因子1誘導細胞凋亡在激素性股骨頭壞死過程中的作用。方法:選擇30例激素性股骨頭壞死組織標本,FicatⅠ期和Ⅱ期患者10例(A組)、FicatⅢ期患者10例(B組)、FicatⅣ期和Ⅴ期患者10例(C組),同時選擇10例接受股骨頸骨折內(nèi)固定手術的正常股骨頭組織標本(D組)。對所有標本在光鏡下觀察測定空骨陷窩率,采用TUNEL凋亡檢測法測定細胞凋亡率,分別采用免疫組化法和ELISA法對磷酸化信號傳導及轉(zhuǎn)錄激活因子1的表達進行定性和定量檢測,同時分別對細胞凋亡率與空骨陷窩率和磷酸化信號傳導及轉(zhuǎn)錄激活因子1表達量進行相關性分析。結(jié)果:4組患者股骨頭空骨陷窩率比較,差異有統(tǒng)計學意義[(29.10±6.14)%,(54.10±7.33)%,(75.25±7.80)%,(7.20±1.32)%,F=227.614,P=0.000]; A組空骨陷窩率高于D組(P=0.000),B組高于A組(P=0.000),C組高于B組(P=0.000)。4組患者股骨頭細胞凋亡率比較,差異有統(tǒng)計學意義[(5.70±3.27)%,(36.90±9.53)%,(70.30±13.63)%,(2.80±2.57)%,F=136.004,P=0.000]。A組和D組比較,差異無統(tǒng)計學意義(P=0.209); B組高于A組(P=0.000),C組高于B組(P=0.000)。4組患者股骨頭磷酸化信號傳導及轉(zhuǎn)錄激活因子1定性檢測結(jié)果比較,差異有統(tǒng)計學意義[(3.15±0.82),(5.97±1.01),(8.56±0.94),(1.00±0.56),F=150.005,P=0.000]。A組高于D組(P=0.000),B組高于A組(P=0.000),C組高于B組(P=0.000)。4組患者股骨頭磷酸化信號傳導及轉(zhuǎn)錄激活因子1定量檢測結(jié)果比較,差異有統(tǒng)計學意義[(1.86±0.43),(5.04±2.24),(11.14±2.49),(1.00±0.28),F=73.466,P=0.000]。A組高于D組(P=0.000),B組高于A組(P=0.000),C組高于B組(P=0.000)。空骨陷窩率和細胞凋亡率呈正相關(rs=0.882,P=0.000),細胞凋亡率和磷酸化信號傳導及轉(zhuǎn)錄激活因子1表達量呈正相關(rs=0.860,P=0.000)。結(jié)論:骨細胞凋亡是激素性股骨頭壞死的重要過程,并且信號傳導及轉(zhuǎn)錄激活因子1可能在其中發(fā)揮了重要作用。
Abstract:
Objective:To explore the effect of bone cell apoptosis induced by signal transducers and activators of transcription-1(STAT1)in the process of steroid-induced necrosis of femoral head(SNFH).Methods:The tissue samples of femoral head were fetched from 30 patients with SNFH.Ten patients(Group A)were categorized as Ficat phaseⅠorⅡ,10 patients(Group B)as Ficat phaseⅢ,10 patients(Group C)as Ficat phase Ⅳ or Ⅴ.Meanwhile,ten normal bone tissue samples(Group D)were obtained from internal fixation surgery for femoral neck fractures.All the samples were observed under the optical microscope and the empty bone lacuna rate were measured,then the TUNEL apoptotic detection method were used to detect the apoptosis rate.After that,qualitative and quantitative detection on the expression of phosphorylated STAT1(p-STAT1)were carried out by immunohistochemical method and ELISA method respectively.Meanwhile,correlation analysis were applied to study the relationship between empty bone lacuna rate and apoptosis rate and between empty bone lacuna rate and p-STAT1 expression.Results:There was statistical difference in the empty bone lacuna rate of femur head among the 4 groups(29.10+/-6.14%,54.10+/-7.33%,75.25+/-7.80%,7.20+/-1.32%,F=227.614,P=0.000).The empty bone lacuna rate was higher in group A compared with group D(P=0.000),was higher in group B compared with group A(P=0.000),and was higher in group C compared with group B(P=0.000).There was statistical difference in the apoptosis rate of femur head between the 4 groups(5.70+/-3.27%,36.90+/-9.53%,70.30+/-13.63%,2.80+/-2.57%,F=136.004,P=0.000).There was no statistical difference in the apoptosis rate of femur head between group A and group D(P=0.209).The apoptosis rate was higher in group B compared with group A (P=0.000)and was higher in group C compared with group B(P=0.000).There was statistical difference in the results of qualitative detection of femur head p-STAT1 between the 4 groups(3.15+/-0.82,5.97+/-1.01,8.56+/-0.94,1.00+/-0.56,F=150.005,P=0.000).Group A surpassed group D(P=0.000),group B surpassed group A(P=0.000),and group C surpassed group B(P=0.000).There was statistical difference in the results of quantitative detection of femur head p-STAT1 between the 4 groups(1.86+/-0.43,5.04+/-2.24,11.14+/-2.49,1.00+/-0.28,F=73.466,P=0.000).Group A surpassed group D(P=0.000),group B surpassed group A(P=0.000),and group C surpassed group B(P=0.000).The results of correlation analysis showed that the empty bone lacuna rate and the expression quantity of p-STAT1 were positively correlated with the apoptosis rate(rs=0.882,P=0.000; rs=0.860,P=0.000).Conclusion:STAT1 may play an important role in bone cell apoptosis,which is important for the process of SNFH.
