多国骨性关节炎和类风湿性关节炎患者艾托考昔和双氯芬酸长疗程(MEDAL)研究的心血管结果:一项随机对比研究

1试验介绍1.1背景非甾类消炎药(NSAIDs)在世界范围内应用广泛,并且在骨性关节炎和类风湿性关节炎患者中需长期应用,但由于胃肠道并发症限制其应用。人们寄希望于选择性环氧化酶2抑制剂(SCOX2-I),能降低胃肠道事件的风险,并避免传统NSAIDs的抗血小板作用。一些大规模试验显示SCO     

加温联合冬凌草甲素抑制肝癌细胞SMMC-7721的生长及其机制探讨

目的:探讨加温联合冬凌草甲素是否具有协同抗肝癌作用,以及二者最佳联合作用模式及其可能的相关作用机制,为临床热化疗治疗肝癌提供实验依据。方法:(1)MTT检测加温与冬凌草甲素合用时对体外培养的人肝癌细胞株SMMC-7721生长的抑制作用,并且评判二者联用是否有协同作用;(2)流式细胞仪检测细胞凋亡率;(3)免疫酶联吸附法定量检测肝癌细胞培养液中AFP;(4)全自动生化仪检测培养液中ALB、ALK。结果:加温与冬凌草甲素单用及合用时均能明显抑制肝癌细胞生长,引起肝癌细胞凋亡,明显降低细胞培养液中AFP值;二者联合作用强度大于单独应用组,并且不同的联合模式产生不同的作用(P<0.05)。结论:(1)加温与冬凌草甲素联合能产生明显协同抑制肝癌细胞生长的作用,作用大小与联合的模式有关。(2)二者抑制肝癌细胞生长的机制与细胞凋亡密切相关。(3)在肝癌的临床治疗中二者联合运用可能产生明显的抑制作用。

痉挛——上运动神经元综合征体征中易混淆的概念

在上运动神经元(UMN)综合征中,有许多以肌肉活动过度活跃为特征的阳性体征,包括巴彬斯基征、阵挛、张力障碍,反射亢进、手足徐动症和痉挛."阴性体征"是指功能的丧失,包括动作灵巧性、力量、协调性和运动控制能力丧失.由于痉挛与UMN综合征其他体征重叠或相似,因此难以讨论痉挛单个的阳性体征,尤其是当UMN综合征的许多阳性体征同时存在时.     

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.     

内蒙古大兴安岭莱姆病自然疫源地全沟硬蜱的季节消长调查

1991年4～8月在内蒙古大兴安岭对莱姆传播媒介全沟硬蜱季节消长、带菌及人群自然感染季节分布等进行调查。结果证明全沟硬蜱是当地蜱类的优势种,从5月上旬发现蜱开始活动,6月上旬为蜱密度高峰期,占总捕数的36％,7月末蜱基本消失。用直接荧光抗体法查蜱带菌率,从采集的549只全沟硬蜱中,检出带菌蜱164只,自然带菌率为29.9％。间接荧光抗体法检测63例被蜱叮咬者血清,其中13例抗体阳性,阳性率为20.6％。本次调查表明,内蒙古大兴安岭林区5～6月为莱姆病媒介全沟硬蜱活动繁殖的高峰期。对63例被蜱叮咬者进行流行病学调查,被蜱叮咬季节与全沟硬蜱季节消长曲线相一致。
