RESUMEN
Spinal infection is a serious health-threatening clinical condition, which more frequently occurs in solid organ transplantation receipients than in non transplant receipients. With the increase of solid organ transplantation, the incidence of secondary spinal infection has been increased in recent years. The symptoms and signs of secondary spinal infection are not obvious, and early diagnosis and treatment are difficult, leading to recurrent attacks and protracted disease courses. This article reviews the progress in the diagnosis and treatment of secondary spinal infection after solid organ transplantation.
RESUMEN
<p><b>OBJECTIVE</b>To study the chemical constituents of the bee-collected rape pollen.</p><p><b>METHOD</b>The compounds were isolated by column chromatography on silica gel; Sephadex LH-20 and C18. Their structures were elucidated on the basis of spectral analysis.</p><p><b>RESULT</b>Nine compounds were isolated from the bee-collected rape pollen and the structures of them were kaemferol-3-O-beta-D-glucosyl-(2-->1)-beta-D-glucoside (1), kaemferol-3,4'-di-O-beta-D-glucoside (2), quercetin-3-O-beta-D-glucosyl-(2-->1)-beta-D-glucoside (3), nicotinic acid (4), nicotinamide (5), trans-p-coumaric acid-4-O-beta-D-glucopyranoside (6), kaemferol (7), beta-sitosterol (8) and 5-hydroxymethylfurfural (9).</p><p><b>CONCLUSION</b>Compounds 1-6 were isolated from the bee-collected rape pollen for the first time.</p>
