Pretreatment with a modified St. Thomas' solution in patients with severe upper limb injuries: Four case reports.

BACKGROUND: This study aims to describe the application of a modified St. Thomas' solution in patients with severe limb injuries. CASE SUMMARY: Four patients who sustained a high-energy trauma and underwent complete upper limb amputation were pretreated with a modified St. Thomas' solution before upper limb replantation. After the perfusion solution stopped flowing from the blood vessel, the amputated upper limb amputation was replanted. The patients were instructed to perform functional rehabilitation training after the operation. All 4 patients were followed up for 5 years. All the severed upper limbs survived. Routine re-examination after the operation showed that the function of the affected limb was restored. All the patients were satisfied with the sensory and functional recovery of the affected limb. CONCLUSION: The modified St. Thomas' solution can effectively improve the success rate of limb salvage surgery and the recovery of limb function in patients with a severe limb injury.

Bilobalide protects against ischemia/reperfusion-induced oxidative stress and inflammatory responses via the MAPK/NF-íœ B pathways in rats.

BACKGROUND: Clinically, skeletal muscle ischemia/reperfusion injury is a life-threatening syndrome that is often caused by skeletal muscle damage and is characterized by oxidative stress and inflammatory responses. Bilobalide has been found to have antioxidative and anti-inflammatory effects. However, it is unclear whether bilobalide can protect skeletal muscle from ischemia/reperfusion injury. METHODS: The effects of bilobalide on ischemia/reperfusion-injured skeletal muscle were investigated by performing hematoxylin and eosin staining and assessing the wet weight/dry weight ratio of muscle tissue. Then, we measured lipid peroxidation, antioxidant activity and inflammatory cytokine levels. Moreover, Western blotting was conducted to examine the protein levels of MAPK/NF-휅B pathway members. RESULTS: Bilobalide treatment could protected hind limb skeletal muscle from ischemia/reperfusion injury by alleviating oxidative stress and inflammatory responses via the MAPK/NF-휅B pathways. CONCLUSIONS: Bilobalide may be a promising drug for I/R-injured muscle tissue. However, the specific mechanisms for the protective effects still need further study.

Aqua-chlorido{6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-dimethyl-idyne)]diphenolato-κO,N,N',O}cobalt(III) monohydrate.

The title compound, [Co(C(18)H(18)N(2)O(4))Cl(H(2)O)]·H(2)O, contains a distorted octa-hedral cobalt(III) complex with a 6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-dimethyl-idyne)]diphenolate ligand, a chloride and an aqua ligand, and also a disordered water solvent mol-ecule (half-occupancy). The Co(III) ion is coordinated in an N(2)O(3)Cl manner. Weak O-H⋯O hydrogen bonds may help to stabilize the crystal packing.

{2,2'-[4,5-Dibromo-o-phenyl-enebis(nitrilo-dimethyl-idyne)]diphenolato-κO,N,N',O'}(methanol-κO)copper(II).

In the title compound, [Cu(C(20)H(12)Br(2)N(2)O(2))(CH(3)OH)], the Cu(II) ion, and the C, O and hydr-oxy H atoms of the coordinated methanol mol-ecule are located on a twofold rotation axis, while the methyl H atoms are disordered over two sites about the rotation axis. The Cu(II) ion is coordinated by two N atoms [Cu-N = 1.960 (4) Å] and two O atoms [Cu-O = 1.908 (4) Å] from the tetra-dentate Schiff base ligand and by one O atom [Cu-O = 2.324 (6) Å] of the methanol molecule in a square-pyramidal geometry. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link complex mol-ecules into extended chains along [001].

3-(4-Pyrid-yl)benzoic acid.

The mol-ecule of the title compound, C(12)H(9)NO(2), is not planar, the benzene and pyridine rings making a dihedral angle of 32.14 (7)°. The carb-oxy group is slightly twisted with respect to the benzene ring by 11.95 (10)°. In the crystal structure, inter-molecular O-H⋯N hydrogen bonds link neighboring mol-ecules into infinite chains along the c axis.
