基于免疫磁珠法的自动化粪便脱落细胞提取仪的研制与应用

Objective To design a device based on immunobead method which enables extraction of exfoliated colonocytes from human feces to become an automatic concentrating process. Methods The automatic device for extraction of exfoliated colonocytes from human feces was designed based on the composition and physiochemical features of the feces as well as the distribution of exfoliated colonocytes, so as to integrate its functions in sample collection, pretreatment, exfoliated colonocyte-immunobead binding,and exfoliated colonocyte- immunobead complex washing. The immunobeads were prepared by coating magnetic beads with monoclonal antibody of epethelial cell adhesion molecule (EpCAM) Ber-EP4 and used to concentrate colorectal cancer cells from cell culture. The binding of colorectal cells to immunobeads was observed under microscopy. Cancer tissues of 10 colorectal cancer patients (or tissues around cancer) were collected. The automatic device for extraction of exfoliated colonocytes from human feces was used to get exfoliated cells from stool specimens of the patients. QRT-PCR was used to detect gene expression of c-myc、cox-2、CD44v6 in tissues and cells collected. Rate of gene positive expression of different original specimens was compared. Results The automatic device for extraction of colonocytes from human feces was designed and manufactured. Extracting exfoliated coloncytes from feces sample was successfully completed by the automatic device and self-prepared immunobeads with coating special monoclonal antibody. The recovery rate of cells was 27%. Rate of c-myc, cox-2 and CD44v6 gene positive expression in cancer tissues or tissues around cancer was 20%, 10% and 20% respectively, and 100% in exfoliated cells from stool specimens. The difference of positive rate among specimens was significant (all P＜0.01). Exfoliated cells from stool specimens collected by the automatic device for extraction of exfoliated colonocytes from human feces were cancer cells. Conclusions As one of the latest-developed approaches, immunobead-based concentration of exfoliated colonocytes appears practical. An automatic device thereby developed may be used for early detection of colorectal cancers.     

肠内和肠外营养对上消化道肿瘤术后肠瘘患者的肠道保护作用

目的研究肠内和肠外营养对上消化道肿瘤术后肠瘘患者的肠道功能保护作用,提高其营养支持效率.方法 28例实验对象,随机分为肠内和肠外营养支持两组,采用前瞻性随机对照研究.结果肠内营养支持可降低循环内毒素水平,减轻肠道缺血再灌注损伤.降低血循环中炎症介质TNF和IL-8的水平.结论肠内营养可有效保护上消化道肠瘘患者的肠道功能,削弱、阻滞"内毒素-炎症介质-肠粘膜损害"这一恶性循环.
