黄芪沙参煎剂对博莱霉素诱导的大鼠肺纤维化模型的干预作用

目的：观察中药黄芪沙参煎剂对肺纤维化大鼠病理、肺泡灌洗液中细胞因子（TGF-β1）表达的影响,探讨黄芪沙参煎剂作用机制,为其临床治疗肺纤维化提供实验依据。方法：取体重190-210g的健康雌性SD大鼠90只,采用随机数字表随机分为6组,每组15只。博莱霉素（B组）、黄芪沙参煎剂高剂量组（H组）、中剂量组（M组）、低剂量组（L组）、强的松组（P组）、生理盐水组（N组）,各组大鼠于造模后第7、14和28天分别随机处死5只。行HE染色、Masson三色染色;右肺支气管肺泡灌洗,收集灌洗液（BALF）,用ELISA法测BALF上清液细胞因子TGF-β1的表达。结果：H组、M组、P组与B组早期肺泡炎和晚期肺纤维化程度比较,差异有统计学意义（P〈0.01）;第7、14、28天P组、H组、M组的BALF中TGF-β1水平与Β组相比差异有显著统计学意义（Ρ〈0.01）。结论：黄芪沙参煎剂具有与强的松相似的疗效,但副反应小、服用方便,可以明显减少肺泡炎症及肺纤维化形成。黄芪沙参煎剂治疗肺纤维化机制可能与早期抑制炎症细胞浸润,减少炎症细胞分泌释放细胞因子TGF-β1,从而抑制成纤维细胞产生胶原和ECM积聚,起到对肺纤维化的治疗作用。

白血病患者造血干细胞移植前单次全身照射的预后分析

Objective To analyze the prognostic factors of patients with leukemia treated with single fraction total body irradiation (SFTBI) followed by hernatopoietic stem cell transplantation (HSCT).Methods From January 2001 to September 2008, 102 patients received HSCT. The differences of the survival rate, relapse rate and incidence of interstitial pneumonia (IP) between groups regarding different genders, ages, pathological types, transplantation methods and TBI parameters were compared and the factors related with the survival rate, relapse rate and incidence of IP were analyzed. Results The followup time ranged from 15 to 1482 days (median, 406 days). The follow-up rate was 95.1%. 86 and 55patients were followed up more than one year and three years. The 1-and 3-year survival rates were 59.0%and 44.0%. In univariate analysis, the 3-year survival rate was signifcantly different between the groups with and without relapse before transplantation (20% vs. 55%, χ2 = 6.33, P = 0. 012), allogeneictranplantation versus autologous tranplantation (39% vs. 68%, χ2 = 8.06, P = 0.005), grade 3 or more acute graft versus host disease (aGVHD) and grade 0 -2 aGVHD (0% vs. 54%, χ2 = 7.52, P = 0.006),with and without relapse after transplantation (19% vs. 58%, χ2 = 10.13, P =0.001), with and without IP (23% vs. 58%, χ2 =8.35, P=0.004). Multivariate analysis showed that grade 3 or more aGVHD was the only statistically significant prognostic factors (χ2 = 12. 74 ,P =0. 000). The l-and 3-year relapse rateswere 30. 0% and 50. 0%. The incidence of relapse was obviously higher in the group with relapse before transplantation than that without (47% vs. 16%, χ2 =7. 32, P=0. 007). Multivariate analysis showed thatrelapse before transplantation was a significant factor predicting relapse after transplantation (χ2 = 9. 39,P =0. 020). The cumulative incidence of IP was 35.0%. The incidence of IP was different between groups with dose homogeneity > 3% and ≤ 3% (27% vs. 4%, χ2 = 5. 21, P = 0. 023), with and without acute parotitis (34% vs. 3%, χ2 = 14. 15, P= 0.000), allogeneic transplantation group and autologous transplantation group (31% vs. 8%, χ2= 7.70, P= 0.006). Multivariate analysis showed that transplantation methods, acute parotitis and dose homogeneity were statistically significant factors in predictingIP (χ2 = 10. 08 , 10. 08 and 7.69 , P = 0. 002 , 0. 002 and 0. 010 , respectively) . Conclusions Patients who develop grade 3 or higher aGVHD have poor prognosis. Dose homogeneity influences the incidence of IP. Patients undergoing allogeneic transplantation are apt to have IP. Acute parotitis is related with IP and might be a predictor.
