RESUMO
This article reports a patient with extensive high-pressure injection injury of the hand combined with deep chemical burn caused by high-pressure injection of industrial cement materials was diagnosed and treated in the Department of Hand Surgery, Xiaolan Hospital Affiliated to Southern Medical University in 2022. The nerves, tendons and blood vessels of the left hand were involved, and the ulnar skin of the left thumb was extensively necrosis, and a large number of extensive cement foreign bodies remained under the skin. Part of the cement was inserted into the joint capsule of the interphalangeal joint. After emergency surgical treatment, the patient was saved successfully, and the wound healed well without chemical poisoning and other related complications, which created conditions for the second stage of flap repair.

Using two flexible Schiff bases, H2L1 and H2L2, two new cobalt II (Co(II))-coordination compounds, namely, Py3CoL1 (1) and Py3CoL2 (2) (Py=pyridine, L1=3,5-ClC6H2(O)C=NC6H3(O)-4-NO2, L2=3,5-BrC6H2(O)C=NC6H3(O)-4-NO2) have been synthesized under solvothermal conditions. Single crystal X-ray structural analysis revealed that compounds 1 and 2 are both six-coordinate in a distorted octahedral geometry, and the 1D chain structure was formed by the π…π and C-H…O interactions or C-H…Cl interaction. The in vitro antitumor activities of 1, 2 and their corresponding organic ligands Py, L1, and L2 were studied and evaluated, in which three human skin cancer cell lines (A-431, HT-144 and SK-MEL-30) were used in the screening tests.
