RESUMEN
With the aid of 1,2-bis(4-pyridyl)ethane (bpee), a nitrogen-donor ligand and 1,3,5-tris(carboxymethoxy)benzene (H3TCMB), a tripodal ether-connector tricarboxylate ligand, two novel transition metal coordination polymers (CPs) have been synthesized via the reaction of Zn(NO3)2·6H2O or Cu(NO3)2·3H2O with the ligands of H3TCMB and bpee ligands with similar reactions under slightly distinct temperatures (80â for 1 and 120â for 2), and their chemical formula are [Cu4(TCMB)2(bpee)2(µ3-OH)2(H2O)2]n·12nH2O (1) and [Zn4(TCMB)2(bpee)2(µ3-OH)2(H2O)2]n·12nH2O (2). Complex 2 can be utilized as a super sensitive fluorescence quenching sensor to determine the Fe3+ ions. The effect of these two compounds on the differentiation of mesenchymal stem cells (MSCs) into the cells of vascular endothelial was further explored.

PURPOSE: Chronic mesenteric ischemia (CMI) is a rare disease that progresses with acute mesenteric ischemia, along with high mortality. How to choose the appropriate surgical method and the artery which should be opened first is the key to the treatment. CASE REPORT: In this study, we successively used vascular bypass and endovascular therapy to treat a case of complex chronic mesenteric ischemia. CONCLUSION: For mesenteric ischemic disease, the superior mesenteric artery (SMA) should be opened preferentially. Arterial bypass or interventional therapy can be used, or both can be combined, to finally achieve the purpose of treatment.
