A new caffeate compound, (E)-erythro-syringylglyceryl caffeate (1), was isolated from the roots and rhizomes of Nardostachys chinensis Batal., together with nine known phenolic compounds, including (+)-licarin A (2), naringenin 4', 7-dimethyl ether (3), pinoresinol-4-O-β-D-glucoside (4), caraphenol A (5), Z-miyabenol C (6), protocatechuic acid (7), caffeic acid (8), gallic acid (9) and vanillic acid (10). Their chemical structures were elucidated on the basis of spectroscopic data and physicochemical properties. Furthermore, this is the first report of compounds 2, 5 and 6 from Nardostachys genus.

Objective Adhesion or too highly located folds upper eyelid and even hlepharoptosis are common complications after double eyelid operation. The method was designed to correct these de-formities. Methods The incision of upper eyelid was designed under the scar. Skin was resected between the former and the new double line, if there was excessive skin. Completely relieve the adhesion until nor-mal tissue was exposed. Expose lateral extension of retro-orbicularis oculi fat pad. An upper pedicle fat flap was formed after cutting tissues off along bilateral borders. Appropriately and transversely cutting lateral portion of the pedicle made it rotate inside downward with enough blood supply. The fat flap was fixed with released orbital fat and the lower edge of fat flat fixed with upper border of supratarsal to restorate the volume. For severe condition, fat granule injection could be used after the skin was sutured. Results 42 cases (80 eyes) were treated in the past two years. The deformities of 32 cases were corrected by the application of retro-orbicularis oculi fat pad. Fat granule injection was applied for the other 10 pa-tients meanwhile. 30 cases (60 eyes) were followed up for 6 to 24 months. The results were satisfactory. Conclusion The methods are performed easily and the results are satisfied. It is worth of recommenda-tion.
