Sesame (Sesamum indicum L. ) belongs to Pedaliaceae, and its dry flowers have been used to cure alopecia, frostbite and constipation as a Traditional Chinese Medicine. Interestingly, the Flos Sesamum indicum L. was usually used to cure verruca vulgaris and verruca plana in folk of China, and showed a pleasant result. Previous chemical investigations of this plant mainly concentrate on its seeds, showed the presence of proteins and fat oils, herein we make a systematic chemical research on the dry flowers of this plant. Column chromatography including silica gel, C18 and Sephadex LH-20 were used to separate the chemical constituents and the structures were determined by chemical and spectroscopic methods. Ten compounds were isolated from the 95% ethanol extract of the plant and elucidated as latifonin (1), momor-cerebroside (2), soya-cerebroside II (3), 1-O-beta-D-glucopyranosyl-(2S, 3S, 4R, 5E,9Z)-2-N-(2'-hydroxytetracosanoyl) 1,3,4-trihydroxy-5,9-octadienine (4), 1-O-beta-D-glucopyranosyl-(2S, 3S, 4R, 8Z)-2-N-(2' R) 2'-hydroxytetracosanoyl) 3,4-dihydroxy-8-octadene (5), (2S, 1" S) -aurantiamide acetate (6), benzyl alcohol-O-(2'-O-beta-D-xylopyranosyl, 3'-O-beta-D-glucopyranoside)-beta-D-glucopyranoside (7), beta-sitosterol (8), daucosterol (9) and D-galacititol (10). Among them, 4 is a new compound, and others were isolated from the flowers of the plant for the first time. Compounds 2 to 4 belong to cerebroside, which is rare to be found in land plants and was proved to possess many bioactivities.

OBJECTIVERecent studies have shown that integrin linked kinase (ILK) plays an important role in the pathogenesis and development of some kidney diseases. This study aimed to investigate the relationship between ILK and renal glomerular damage in children with Henoch schonlein purpura nephritis (HSPN).

METHODSOne hundred and eighty eight HSPN children (aged 3 to 17 years) were assigned to five groups according to the classification of the International Study of Kidney Disease in Children (ISKDC): grade < or = IIa (n = 62), grade IIb (n = 42), grade IIIa (n = 29), grade IIIb (n = 40) and grade > or = IV (n = 15). Fifteen children with basement membrane nephropathy served as the control group. ILK expression on glomeruli was ascertained by immunohistochemical staining. The relationships of ILK expression on glomeruli with glomerular histopathologic lesions and urinary protein excretions were examined.

RESULTSThe positive areas of ILK expression on glomeruli in the control, grade < or = IIa, grade IIb, grade IIIa, grade IIIb and grade > or = IV groups were (3.35 + or - 1.01)%, (4.88 + or - 1.13)%, (9.64 + or - 1.36)%, (11.27 + or - 1.68)%, (17.42 + or -3.0)% and (20.62 + or - 2.32%), respectively. There were significant differences in the ILK expression between groups (p<0.01). ILK expression on glomeruli increased with increased urinary protein excretions. There were significant differences in the ILK expression in children with different urinary protein excretions (p<0.01).

CONCLUSIONSILK might be involved in the process of renal glomerular histopathologic damage and the production of proteinuria in children with HSPN.

OBJECTIVETo modify a percutaneous transpedical interbody bone grafting apparatus for better surgical performance in transpedical interbody bone grafting.

METHODSThe puncture needle, guide pin and expander were removed from the original design of interbody bone grafting apparatus, with also modification of the bone grafting funnel, obturator, wick and bone harvesting device. Percutaneous puncture and transpedical interbody bone grafting were performed using the modified apparatus on two cadavers, and the operative procedures, bone grafting scope and surgical trauma were observed.

RESULTSThis modified apparatus allowed increased bone grafting scope with shortened operative time, simplified operation procedures, and reduced surgical trauma.

CONCLUSIONPercutaneous puncture and transpedical interbody bone grafting can be easily and safely performed with the modified apparatus.

OBJECTIVETo develop a percutaneous and transpedical interbody bone grafting apparatus for vertebral bone defect reconstruction in thoracolumbar fracture correction via minimally invasive operation.

METHODSThe percutaneous and transpedical interbody bone grafting apparatus was designed with CAD software, and the reduction effect, range of bone grafting and surgical complications of the apparatus were investigated in adult cadaveric thoracolumbar body and with computerized surgical simulation.

RESULTSThe self-designed apparatus was convenient for percutaneous and transpedical interbody bone grafting that did not give rise to complications. CT showed large bone grafting area with increased density in the vertebral body corrected with this apparatus.

CONCLUSIONThe designed apparatus allows easy manipulation and efficient bone grafting and repositioning. Minimally invasive interbody bone grafting in thoracolumbar fracture can be easily performed with proper application of the apparatus.
