Objective To prepare the immunotoxin protein (183B 2ScFvPE38) which might be useful in immuno guided therapy for ovarian carcinoma and study the activity of the protein. Methods The methods of ELISA and cytotoxicity were used to study the immunotoxin after induced with IPTG and the activity of the immunotoxin. Results The expressed fusion proteins were detected mostly as inclusion bodies at high level, and soluble immunotoxins were also observed. The results showed liable activity of antibody part and toxic part. Conclusion The recombinant fusion protein 183B 2ScFvPE38 keeps the activity of both components and might be of great use in the future to deal with ovarian carcinoma. [

Crocetin, a naturally occurring carotenoid, possesses antioxidant and antiatherosclerotic properties, of which the underlying mechanism remains unclear. In the present study, we examined the effects of crocetin (0.1, 1, 10 μmol·L(-1)) on angiotensin II (Ang II, 0.1 μmol·L(-1)) induced expression of vascular cell adhesion molecule-1 (VCAM-1) in human umbilical vein endothelial cells (HUVECs) and monocyte-endothelial cell adhesion. The effects of crocetin on the activation of nuclear factor kappa B (NF-κB) and intracellular reactive oxygen species (ROS) were also observed. The results demonstrated that crocetin notably suppressed Ang II induced NF-κB activation (P<0.01) and VCAM-1 expression (P<0.05, P<0.01) in HUVECs, accompanied by a markedly reduced monocyte-endothelial cell adhesion (P<0.05, P<0.01). In addition, preincubation with crocetin resulted in a significant enhancement of cellular antioxidant capacity (P<0.05, P<0.01), while Ang II induced intracellular ROS decreased markedly (P<0.05, P<0.01). These results indicated that crocetin was capable of suppressing Ang II induced VCAM-1 expression and monocyte-endothelial cell adhesion by suppression of NF-κB activation, which might be derived from the enhancement of antioxidant capacity and subsequent reduction of intracellular ROS.

10.Features and management of very early onset inflammatory bowel disease.
Chinese Journal of Contemporary Pediatrics 2018;20(5):341-345
Inflammatory bowel disease (IBD) is a chronic nonspecific intestinal inflammatory disease of unknown etiology. This disease includes three main types: Crohn′s disease (CD), ulcerative colitis (UC), and IBD-unclassified (IBD-U). IBD is frequently presented in adults, but in recent years, there is a rising incidence in pediatric populations. Very early onset IBD (VEO-IBD) is a fraction of pediatric IBD, but they have exclusive phenotypic and genetic characteristics such that they are accompanied by severe disease course and resistance to conventional therapy. The purpose of this review is to provide a contemporary overview of the clinical features, pathogenesis, and management of VEO-IBD.
