Objective To explore the aesthetic efficacy of modified endoscopic rhytidectomy by using the techniques to minimize tissue damage,to obviate injury to the vessels and nerves,and to control bleeding and to firm fixation.Methods Two discontinuous incisions were made in the temporal scalp during the procedure,obviating injury to the branches of the superficial temporal vessels.Endoscopic technique was used to facilitate elevating,hemostasis,slinging and fixation in the plane under superficial temporal fascia.Three transverse incisions were made after the hairline in the forhead scalp,the operation was carried out by using endoscopic equipment,and the elevated forhead flap was slinged and fixed upward to the lamina externa cranii.Results 58 cases were received endoscopic forehead and temporal rhytidectomy,only slight edema was observed after surgery,and no obvisous ecchymosis was found.All patients returned home 7 days after operation.Degree of satisfaction on long-term follow-up showed that 56 cases(96.55%)improved obviously one year postoperatively;35 cases followed up 2 years,33(94.29%)of them improved obviously.None case was suffered from facial nerve injury.Conclusion The purpose of endoscopic rhytidectomy is to avoid carrying out the operation out of sight,to minimize unexpected damage to vessels and nerves,and to facilitate dissection,hemostasis,suturing,slingling and fixation.By refining the technique,we can achieve minimal injury,shorten recovery period,and obtain more satisfactory results,so the indication for operation is extended.

The UL49.5 gene of most herpesviruses is conserved and encodes glycoprotein N. However, the UL49.5 protein of duck enteritis virus (DEV) (pUL49.5) has not been reported. In the current study, the DEV pUL49.5 gene was first subjected to molecular characterization. To verify the predicted intracellular localization of gene expression, the recombinant plasmid pEGFP-C1/pUL49.5 was constructed and used to transfect duck embryo fibroblasts. Next, the recombinant plasmid pDsRed1-N1/glycoprotein M (gM) was produced and used for co-transfection with the pEGFP-C1/pUL49.5 plasmid to determine whether DEV pUL49.5 and gM (a conserved protein in herpesviruses) colocalize. DEV pUL49.5 was thought to be an envelope glycoprotein with a signal peptide and two transmembrane domains. This protein was also predicted to localize in the cytoplasm and endoplasmic reticulum with a probability of 66.7%. Images taken by a fluorescence microscope at different time points revealed that the DEV pUL49.5 and gM proteins were both expressed in the cytoplasm. Overlap of the two different fluorescence signals appeared 12 h after transfection and continued to persist until the end of the experiment. These data indicate a possible interaction between DEV pUL49.5 and gM.
