微板紫外速率法漏检高值ALT标本一例

谷丙氨基转移酶（Alanine asninotrasferase，ALT）检测是采供血机构血液必检项目之一，ALT检测作为早期肝病诊断的一项非特异性指标，有助于鉴别与输血相关肝炎病毒携带者，同时可以在一定程度上弥补某些肝炎病毒标志物未被检测及“窗口期”的缺陷，有助于预防输血相关肝炎的传播。我血站实验室采用微板为载体的方法进行血清ALT检测：微板紫外速率法为初检方法；微板丙酮酸氧化酶法为复检方法。在检测过程中一例高值ALT血样，微板紫外速率法检测结果为6．6U／L，出现假阴性结果造成漏检，现报告如下：

Plasmid DNA encoding transforming growth factor-beta1 suppresses chronic disease in a streptococcal cell wall-induced arthritis model.

Transforming growth factor beta is a potent immunomodulator with both pro- and antiinflammatory activities. Based on its immunosuppressive actions, exogenous TGF-beta has been shown to inhibit autoimmune and chronic inflammatory diseases. To further explore the potential therapeutic role of TGF-beta, we administered a plasmid DNA encoding human TGF-beta1 intramuscularly to rats with streptococcal cell wall-induced arthritis. A single dose of 300 microg plasmid DNA encoding TGF-beta1, but not vector DNA, administered at the peak of the acute phase profoundly suppressed the subsequent evolution of chronic erosive disease typified by disabling joint swelling and deformity (articular index = 8.17+/-0. 17 vs. 1.25+/-0.76, n = 6, day 26, P < 0.01). Moreover, delivery of the TGF-beta1 DNA even as the chronic phase commenced virtually eliminated subsequent inflammation and arthritis. Both radiologic and histopathologic as well as molecular evidence supported the marked inhibitory effect of TGF-beta1 DNA on synovial pathology, with decreases in the inflammatory cell infiltration, pannus formation, cartilage and bone destruction, and the expression of proinflammatory cytokines that characterize this model. Increases in TGF-beta1 protein were detected in the circulation of TGF-beta1 DNA-treated animals, consistent with the observed therapeutic effects being TGF-beta1 dependent. These observations provide the first evidence that gene transfer of plasmid DNA encoding TGF-beta1 provides a mechanism to deliver this potent cytokine that effectively suppresses ongoing inflammatory pathology in arthritis.

石家庄地区汉族人群DIS80(pMCT118)位点VNTR基因频率分布调查

本文采用ＰＣＲ技术对石家庄地区２１６名无关个体ＤＩＳ８０（ｐＭＣＴ１１８）位点扩增片段长度多态性的等位基因频率进行调查。ＰＣＲ扩增产物采用聚丙烯酰胺凝胶电泳分型及溴化乙锭染色，共检出７０种基因型，２５个等位基因，其中以１８、２４、３０三个等位基因频率最高。将本文结果与日本人群在ＤＩＳ８０（ｐＭＣＴ１１８）位点多态性结果进行比较，石家庄地区汉族人群ＤＩＳ８０（ｐＭＣＴ１１８）位点基因频率分布符合ＨａｒｄｙＷｅｉｎｂｅｒｇ平衡定律，该位点非父排除率为０．７１，个体识别率为０．９，杂合度为０．８５。     

Diagnosis of ligament rupture of the ankle joint: Physical examination, arthrography, stress radiography and sonography compared in 160 patients after inversion trauma

We prospectively enrolled 160 consecutive patients with inversion trauma of the ankle in a diagnostic protocol that included physical examination within 2 days and at 5 days after trauma, arthrography, stress radiography, and ultrasonography. 135 patients had pathological lateral ligament laxity on the later physical examination or lateral ligament rupture diagnosed on arthrography and they were operated on. 122 of these patients had ligament ruptures.

At clinical follow-up after a minimum of half a year, all of the patients who were not operated on had stable joints without signs of previous ligament ruptures.

Delayed physical examination at 5 days after the injury led to the highest overall sensitivity (96%) and specificity (84%) for the detection of a ligament rupture. Additional diagnostic procedures, at a considerable cost, yielded little additional information.
