Objectives To study the effect of D.L-Glyceraldehyde(D.L-GA) on preserve blood glucose concentration.Methods Heparinized blood from volunteers and diabetic patients was added into tubes in which contained or without D.L-GA. After incubation for various times. Plasma glucose and other common clinical biochemical tests were determined with biochemistry analyzers.Results Glucose concentration was effectively preserved in whole blood specimens by 4 0mmol/L D.L-GA. Blood glucose concentration in the specimens treated with 8 0mmol/L D.L-GA were stable and most routine biochemical tests were uninterfered by the presence of D.L-GA.Conclusions D.L-GA effectively preserves glucose concentration in whole blood specimens within 8h. Specimens treated with 8.0mmol/L D.L-GA are suitable for analysis of clinicial routine biochemical tests including determination of blood glucose concentration.

Objective:To investigate the clinical effect of orbital septal fascia advancement in the correction of mild blepharoptosis.Methods:From December 2016 to January 2020, a total of 77 eyes of 56 patients with mild congenital ptosis who underwent double eyelid surgery were treated. The method of orbital septal fascia advancement was used to correct mild ptosis. Specifically, during double eyelid reconstruction, the orbital septum was opened and the orbital septal fascia about 2 mm in front of the fold was preserved. The posterior lip of the orbital septal fascia was pulled down to the upper part of the tarsal plate, and fixed on the tarsal plate with 3 stitches of 5-0 nylon suture, and appropriate adjustments were made to correct mild ptosis.Results:Patients (56 eyes of 40 cases) were followed up from 6 to 12 months (average 7.4 months), 46 eyes (82.1%) were satisfied with blepharoptosis correction, 8 eyes (14.3%) were basically satisfied with blepharoptosis correction, and 2 eyes (3.6%) were dissatisfied with blepharoptosis correction. 45 eyes (80.4%) were satisfied with blepharoplasty, 7 eyes (12.5%) were basically satisfied with blepharoplasty, and 4 eyes (7.1%) were dissatisfied with blepharoplasty. No double eyelid folds disappeared after surgery, and there were no complications such as incomplete closure, conjunctival prolapse, or exposed keratitis.Conclusions:The correction effect of blepharoptosis is good, and the reconstruction structure is stable with natural appearance, fast recovery and high satisfaction. Therefore, the method can be popularized.
