大豆异黄酮对初老大鼠卵巢Bcl-2基因和Caspase-3基因mRNA表达的影响

目的观察大豆异黄酮(soy isoflavones,SI)对初老大鼠卵巢Bcl-2、Caspas e-3 mRNA表达及氧自由基含量的影响。方法利用自然衰老的雌性大鼠建立初老动物模型,连续灌胃给药8周后,采用逆转录-聚合酶链反应(RT-PCR)检测卵巢Bcl-2和Caspase-3 mRNA表达,采用硫代巴比妥酸和黄嘌呤氧化法分别检测卵巢丙二醛(MDA)含量和超氧化物歧化酶(SOD)活性。结果与初老组相比,各SI处理组卵巢Bcl-2 mRNA表达量和SOD的活性均明显增高、Caspase-3表达量明显下降,中剂量(158 mg.kg-1)和高剂量(500 mg.kg-1)SI处理组MDA含量也显著降低(P<0.05或P<0.01)。结论大豆异黄酮上调卵巢Bcl-2、下调Caspase-3表达、抑制氧自由基生成并增强SOD活性,可能是其改善衰老卵巢功能的机制之一。     

OSAHS患者综合治疗对血清sTNF—R工水平的影响

目的：了解OSAHS患者血清可溶性肿瘤坏死因子受体-I（sTNF-RI）的水平,评估0sAHs患者综合治疗对血清sTNF—RI水平的影响。方法：选择62例经多导睡眠监测仪诊断的OsAHS患者为实验组,15例非0SAHS患者为对照组。选取中重度组患者进行治疗前和治疗3个月后做前后对照比较,用酶联免疫吸附实验（ELISA）方法检测非OSAHS患者及OSAHS患者基础水平以及中重度组综合治疗前后血清sTNF—RI水平。结果：①实验组血清sTNF-RI水平（742±258pg／m1）较对照组（340±102pg／m1）明显升高（P〈O．05）;②中重度OSAHS治疗组患者血清sTNF-RI水平（351．4±116．9pg／m1）较治疗前（834．1±233．8pg／m1）明显降低（P〈0．05）;③控制体重、年龄、体质指数、性别等混杂因素后血清sTNF—RI水平与AHI呈正相关（r=0．646,P〈0．01）,与夜间最低氧饱和度呈负相关（r=0．522,P〈0．01）。结论：在控制体重、年龄、体质指数等混杂因素后,OSAHS患者严重程度与血清sTNF-RI有一定的相关性,综合治疗可以降低OSAHS患者血清sTNF-RI水平。

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.
