实时荧光定量PCR检测布鲁杆菌方法的应用

Objective To discuss a real-time fluorescence quantitative polymerase chain reaction (FQ-PCR) wether if can be used to detect Brucella. Methods According to the BCSP31 gene sequences specific for Brucella, one pair of primers and one TaqMan probe were designed. A real-time PCR was developed with the BCSP31 fragments cloned into PMD18-T vector. The standard cure was established and the sensitivity, the species specificity and the stability of the assay were evaluated. The clinical blood specimens were detected by QT-PCR and compared with clinical diagnosis. Results The standard curve was established with the standard template and the relationship between the Ct and the DNA copy number was linear(r=0.999). The sensitivity of the real-time PCR was 5 copies/μl. The sensitivity of the common PCR was 5×102 copies/μl. The sensitivity was about 100 times higher than common PCR. Species specificity of this FQ-PCR assay evaluated using genomic DNA from 6 Bmcella strains and 5 non-Brucella strains and strong fluorescence was detected in all Brucella strains. The CV of intra-assay and inter-assay reproducibility were 0.71%,7.23%, reprectively. Twenty-four specimens from clinical brucellosis cases, 19 showed positive, the positive coincident rate was 79%(19/24). The negative results were obtained for all 31 negative control, and the negative coincident rate was 100%(31/31). Two were positive from all 30 specimens clinically suspected. Conclusions Highly specific, sensitive, repeatable and coincidental with clinic, this FQ-PCR is quite useful for rapid detection of tiny DNA of Brucella in various samples and laboratory diagnosis.     

成人颈椎椎弓根螺钉在儿童腰椎应用的可行性

背景：由于1～3岁幼年儿童椎体发育未完全成熟,各种解剖径线相对较成人小得多,尚无幼儿专用的椎弓根螺钉固定器械,现有能够利用的直径最小的椎弓根螺钉是用于成人颈椎侧块或椎弓根固定的钉棒系统。目的：观察将成人颈椎椎弓根螺钉应用到成年猪颈椎与幼猪腰椎固定后的生物力学对比。方法：将6具完整新鲜成年猪颈段C3～C6脊椎标本和6具完整8周龄新鲜幼猪腰段脊柱标本自椎间盘及关节处离断,游离成单个椎体,共54个椎体108侧椎弓根。按照标准操作将成人颈椎椎弓根螺钉分别安置在成年猪颈椎标本和幼猪腰椎标本的椎弓根上,应用生物力学方法测试螺钉的最大轴向拔出力。结果与结论：颈椎标本最大轴向拔出力高于腰椎标本,但差异无显著性意义（P〉0.05）;L1椎弓根螺钉的拔出力均值明显小于L3椎弓根螺钉的拔出力均值（P〈0.05）;C5椎弓根螺钉的拔出力均值明显大于C3椎弓根螺钉的拔出力均值（P〈0.05）;颈椎和腰椎标的骨密度差异有显著性意义（P〈0.01）,椎体椎弓根力学数值与椎体骨密度之间存在线性正相关。说明取得了成人颈椎椎弓根螺钉在轴向拉力方面适应于幼儿腰椎的初步实验依据。     

热化疗前后恶性肿瘤患者淋巴细胞亚群及IL-2、sIL-2R的动态观察

全身热化疗（WBH—CT）已经应用于各种恶性肿瘤疾病的治疗，其机制仍缺乏确凿证据，但其治疗效果被认为与免疫系统的激活相关。我们对25例恶性肿瘤患者进行WBH—CT前后多个时相的外周血样本动态观察，报道如下。

复方丹参注射液抗脂多糖诱导的兔弥漫性血管内凝血

目的: 研究复方丹参注射液对脂多糖(LPS)诱导的兔弥漫性血管内凝血(DIC)的作用。方法: 用LPS诱导兔DIC模型。凝固法测定纤维蛋白原含量,全自动凝血分析仪检测活化部分凝血活酶时间(APTT)、凝血酶原时间(PT)和纤维蛋白原含量;全自动血细胞分析仪进行血小板计数;全自动血浆分析仪测定谷丙转氨酶(ALT)以及血尿素氮(BUN);发色底物法测定蛋白C及抗凝血酶Ⅲ的活性。观察复方丹参注射液对LPS诱导的兔DIC的拮抗作用。结果: 兔耳缘静脉持续滴注LPS,观察到:APTT和PT显著延长;血小板计数和纤维蛋白原含量明显减少;ALT和BUN显著升高;蛋白C和抗凝血酶Ⅲ的活性明显降低。给予复方丹参注射液后,APTT和PT的延长明显缩短;血小板计数和纤维蛋白原的含量均明显恢复;ALT和BUN显著下降;蛋白C及抗凝血酶Ⅲ的活性显著改善。结论: 复方丹参注射液对LPS诱导的兔DIC有良好的拮抗作用。
