摘要 目的探讨慢性乙型肝炎(CHB)患者丙氨酸转氨酶(ALT)水平与乙型肝炎病毒(HBV)特异性细胞毒性T淋巴细胞(CTL)、非特异性CTL的关系。方法148例CHB患者根据ALT水平分为3组:甲组35例,ALT≥2×正常值上限(ULN)~5×ULN(100~250IU/L);乙组53例,ALT〉5×ULN~≤10×uLN(251~500IU/L);丙组60例,A岍〉10×ULN(〉500IU/L),用流式细胞仪检测非特异性CTL,对其中74例(甲组17例,乙组27例,丙组30例)人白细胞抗原(HLA)-A2阳性CHB患者检测HBV特异性CTL。比较三组的HBV特异性CTL、非特异性CTL、HBVDNA水平和HBeAg阳性率。结果HBV特异性CTL:甲组[(0.42±0.10)%]高于乙组[(0.25±0.08)%],t=6.37,P〈0.01,乙组高于丙组[(0.17±0.004)%]t=5.14,P〈0.01。非特异性CTL:甲组[(15.01±3.01)%]低于乙组[(18.1±5.02)%],t=2.81,P〈0.01,乙组低于丙组[(21.5±6.11)%]t=3.07,P〈0.01。HBVDNA水平:甲组[(4.97±0.86)log^10拷贝/ml]低于乙组[(5.92±0.92)log^10拷贝/ml],t=4.87,P〈0.01,乙组低于丙组[(6.37±0.71)log^10拷贝/ml]t=2.92,P〈0.01。HBeAg阳性:甲组15例(42.86%),低于乙组(32例,占60.38%),χ^2=2.59,P〉0.05,乙组低于丙组(41例,占68.33%),χ^2=0.788,P〉0.05,甲组低于丙组χ^2=5.929,P〈0.05。结论CHB患者非特异性CTL越高,AIJT水平越高^[1],而HBV特异性CTL越低,HBV复制越强。 Objective To explore relations between ALT level and hepatitis B virus (HBV) specific CTL and non-specific CTL in patients with chronic hepatitis B (CHB). Methods 148 cases of CHB were divided into three groups according to ALT level. 35 cases in group A, ALT≥2 × upper limit of normal value (ULN)--5 × ULN (100--250 IU/L) ; 53 cases in group B, ALT 〉 5 × ULN--≤ 10 × ULN (251--500 IU/L) ; 60 cases in group C, ALT 〉 10 × ULN( 〉 500 IU/L) . Flow cytometry is used to determine non-specific CTV. HBV specific CTL was tested on 74 cases of CHB (17 in group A, 27 in group B and 30 in group C) with positive (HLA)-A2. Compare HBV specific CTL, non-specific CTL, HBV DNA levels and positive rate of HBeAg. Results HBV specific CTL: Group A (0.42 ±0. 10) % is higher than group B (0.25 ± 0.08) %, t = 6.37, P 〈 0.01, group B is higher than group C (0.17 ± 0.004)%, t = 5.14, P 〈 0.01; Non-specific CTL: Group A (15.01 ± 3.01)% is lower than group B (18.1 ±5.02)%, t =2.81, P 〈0.01, group B is lower than group C (21.5 ± 6.11)%, t = 3.07, P 〈 0.01 ; HBV DNA level : Group A [ (4.97 ± 0.86) log^10 copies/ml] is lower than group B [ (5.92 ± 0.92) log^10 copies/ml], t = 4.87, P 〈 0.01. Group B is lower than group C [ (6.37 ± 0.71) log^10 copies/rnl], t = 2.92, P 〈 0.01 ; Positive HBeAg: Group A (15 cases, 42.86% ) is lower than group B (32 cases, 60.38% ), 2 = 2.59, P〉0.05. Group B is lower than group C (41 cases, 68.33%), χ^2 = 0.78, P 〉 0.05. Group A is lower than group C, χ^2 = 5.929, P 〈 0.05. Conclusion The higher the non-specific CTL of patients with CHB is, the higher the ALT level would be, whereas the lower the HBV specific CTL is, the stronger the HBV replication would be.
