目的:比较三种不同便潜血检测方法的优劣性,寻找效果最好的联合检测方法。方法:使用化学法、单克隆抗体法和联合免疫法检测消化道肿瘤患者和正常人群便潜血,分别计算其阳性率。并使用不同浓度血红蛋白分别检测单克隆抗体法和转铁蛋白法的灵敏度。结果:化学法、单克隆抗体法和联合免疫法检测便潜血的阳性率分别是92.3%,94.6%和99.2%。转铁蛋白法灵敏度是0.1mg/L,单克隆抗体法灵敏度是0.02mg/L。结论:便潜血中转铁蛋白法的稳定性高于单克隆抗体法,但是灵敏度低于单克隆抗体法,所以两种方法的联合使用,可以很好的提高便潜血检测准确率。  相似文献

胃液潜血单克隆抗体法假阴性实例试验初探   总被引:3,自引:0,他引:3  
目的:针对胃液潜血单克隆抗体法假阴性实例进行初探试验。方法:采用联苯胺和单克隆抗体两种方法,对1例经不同方法处理的胃液标本同步进行潜血试验。结果:联苯胺法:经不同方法处理后的各组标本,测得结果均呈强阳性至阳性。单克隆抗体法:原胃液标本测得阴性,稀释后的A1~3组均测得阴性,加入血红蛋白液后的B1~3组测得结果均为阳性,孵育12h后的C1~3组结果为弱阳性至阳性,孵育24h后的D1~3组结果为阴性至弱阳性,单纯血红蛋白组结果为阳性。结论:该例胃液标本中存在内源或外源性物质,致使患血红蛋白免疫原活性降低或丧失,导致临检胃液潜血单克隆抗体法多次呈假阴性结果。提示,临床检验中应注意结合患临床症状,对可疑标本采用其他化学法复检,以求其真。  相似文献

CASE HISTORY A female patient, 46 years old, head of the foreign affairs department of a certain university in Beijing, paid her first visit on October 9, 2006, with the chief complaint of vomiting for one month. She got vomiting after meals in early September. Before that, she had discomfortable sensation in the stomach due to angry with others, but she didn't pay much attention. Later, it developed into vomiting after eating. After the vomiting, the discomfort would be relieved, but with slight hypodynamia. She was once diagnosed as having 'neurogenic vomiting'. Having taken some western and Chinese drugs, the above symptoms were a little bit improved, but she would have nausea upon eating and with regurgitation. Because of the fear for vomiting, she did not dare to have food intake, with body weight reduction of 6 kilos in one month.  相似文献

OBJECTIVE: To observe therapeutic effects of the comprehensive therapy of acupuncture-moxibustion and Chinese Tuina for treatment of insomnia due to deficiency of both the heart and spleen. METHODS: 92 cases were divided randomly into the treatment group (treated by acupuncture-moxibustion and Chinese Tuina) and the control group (treated by acupuncture-moxibustion). RESULTS: The therapeutic effect of the treatment group was obviously superior to that of the control group (the CHI2 test showed P < 0.01). CONCLUSIONS: The comprehensive therapy of acupuncture-moxibustion and Chinese Tuina can give marked therapeutic effects for treatment of insomnia due to deficiency of both the heart and spleen.  相似文献

Objective: To investigate if there are the CK-19, PDX-1, Nestin, Ngn3 positive cells in the donor islets of different purity in rats. Methods: Thirty male adult SD rats were randomly divided into 3 groups. Islets were isolated using digestion by ductal injection of collagenase. Group Ⅰ (n=10): Separating cell preparations were not purified, Group Ⅱ(n=10): Islet sediment was purified with 25% Ficoll400 ,Group Ⅲ (n=10): Islet sediment was purified with 25% and 11% Ficoll-400. The levels of protein of CK-19, PDX-1, Nestin and Ngn3 were detected by immunohistochemistry and the mRNA of CK-19, PDX-1, Nestin, Ngn3 was amplified by RT-PCR. Results: After two different purification methods applied, three islet preparations of different purities were obtained. The difference of islet purity was significant among various groups (P<0.05). Compared with group Ⅱ and group Ⅲ,the protein and mRNA of CK-19, PDX-1, Nestin,Ngn3 were both higher in group Ⅰ; group Ⅲ was poorly expressed. Conclusions: The three different islet purity donor islet have different CK-19, PDX-1, Nestin, Ngn3 positive cells within them, indicating that there are some islet stem cells in the purified donor islet.  相似文献

Objective:To investigate the optimum screening conditions of associated proteins in human psoriasis vulgaris by serum proteomics technique, and to screen the different expression proteins related with psoriasis vulgaris. Methods:Serum samples of peripheral blood were collected from newly diagnosed psoriasis vulgaris patients in the clinic, and 20 matched healthy persons. Serum albumin IgG was removed by filtering with ProteoExtract Albumin/IgG. After comparative proteomics analysis the different protein spots were identified using 2-DE and MS. Results :Electrophoresis figures with high resolution and reproducibility were obtained. Three different expression proteins were found only in the serum from psoriasis vulgaris patients, while nine other different proteins expressing from healthy volunteers. Conclusion:The protein expression was different in the serum between the psoriasis vulgaris patients and healthy volunteers. It was hoped that we could find the biomarkers related to psoriasis vulgaris by using proteomics.  相似文献
