Therapeutic properties, biological effects, antiliver cancer, and anticolon cancer effects of some natural compounds: A biochemical approach.

Natural compounds, such as carotenoids, flavonoids, anthocyanins, or terpenoids, are physiologically active components found in plants (pigments), often known as phytochemicals or phytonutrients. The in vitro cytotoxic and anticolon cancer effects of biologically bavachin, bavachinin, artepillin C, and aromadendrin compounds against SW48, SNU-C1, COLO 205, RKO, LS411N, and SW1417 cancer cell lines were assessed. Results of enzymes and antibacterial, antifungal were in level of micromolar that is good impacts. These natural compounds may be antidiabetic, anticancer, and antibacterial candidates for drug design. IC50 results were obtained between 14-19 and 5-119 µM for α-amylase and α-glucosidase, respectively. Good inhibitor Bavachinin was detected for both enzymes (IC50 for α-amylase: 14.37 µM and IC50 for α-glucosidase: 5.27 µM). The chemical activities of aromadendrin, artepillin C, bavachin, and bavachinin against pancreatic α-amylase and α-glucosidase were assessed by conducting the molecular docking study. The chemical activities of aromadendrin, artepillin C, bavachin, and bavachinin against some of the expressed surface receptor proteins (CD44, CD47, CXCR4, EGFR, folate receptor, HER2, and endothelin receptor) in the mentioned cell lines were investigated using the molecular docking calculations. The results illustrated the atomic-level properties and potential interactions. These chemicals have high binding affinities to the enzymes and proteins, according to the docking scores. In addition, the compounds formed strong contacts with the enzymes and receptors. Thus, these compounds could be potential inhibitors for enzymes and cancer cells.

[Treatment on post-operational complications of aortic endovascular grafting exclusion].

OBJECTIVE: To investigate the post-operative complications of aortic endovascular grafting exclusion (EVGE) and its reasons and treatments. METHODS: Clinical data of 82 cases received aortic endovascular grafting exclusion from January 2002 to October 2008 were retrospectively analyzed. Seventy-one cases were male and 11 cases were female with the age of 33 to 78 years and the average age of 49.2 years. There were 66 cases of thoracic aortic dissecting aneurysms and 16 cases of abdominal aortic aneurysm. The effect, post-operational complications and its treatment were investigated. RESULTS: There were 90.1% patients had been followed up with the time of 3 to 78 months with technical success of 90.3%, clinical success of 94.1%, peri-operational mortality of 2.4%, total mortality of 6.1% and mortality associated with EVGE of 2.4%. Twenty-one cases underwent complications including type I endoleak (13 cases), abdominal aortoduodenal fistula (1 case), narrow true lumen (2 cases), reverse Stanford A dissection (2 cases), post EVGE syndrome (12 cases), delayed healing of inguinal incision (5 cases), constipation (3 cases), cerebral infarction (1 case). No paraplegia, left subclavian artery ischemia, contrast media associated nephrosis, ischemic colitis, ischemic neurologic injury, and artery embolism occurred. Post operation 4 cases had the second intervention including 2 type I endoleak and 2 narrow true lumen. CONCLUSIONS: The technique-related complications still hinder the long-term effect of EVGE. It needs to be further investigated on technique improvement and treatment standardization.
