Objective:To evaluate the specific changes and importance of the proportions of the eyebrows and eyes after surgery by analyzing and measuring the changes of the values of the eyebrows and eyes in elderly patients with aponeurotic ptosis before.Methods:A total of 54 cases (108 eyes) of elderly patients with aponeurotic ptosis who were treated in our department from 2019.01 to 2020.12 were collected preoperatively and 6 months postoperatively, and they were set as the study group. At the same time, the data of 48 cases (96 eyes) of healthy people with good face were collected and set as the young control group, and the data of 50 cases (100 eyes) of elderly healthy people without ptosis were collected and set as the elderly control group. The corresponding objective data were analyzed, and the specific changes and proportional relationship of eyebrows and eyes after surgery were evaluated.Results:Compared with the preoperative data, the marginal reflex distance 1 (MRD1), the height of the palpebral fissure (HPF) in the study group increased at 6 months after the operation, and the distance between the eyebrow and eye at each site increased or shortened ( P<0.05). Six months after the operation, the brow height from medial canthus (MBH), the central brow and eye distance (brow height from upper eyelid margin on midpupillary level, CBH), and the lateral brow and eye distance (brow height from lateral, LBH) had been changed. The change rates of canthus compared with preoperatively were that (88.29±11.69)%, (85.04±14.96)%, and (93.61±13.56)%, respectively, among which CBH shortened most significantly, and the shortened distance was (3.76±2.43) mm. The MRD1 and HPF in the group increased significantly at 6 months after operation, which were significantly greater than those in the elderly control group ( P<0.05). CBH was significantly shortened ( P<0.05); compared with preoperative, the ratio of HPF/CBH, HPF/length of the palpebral fissure (LPF) in the study group increased at 6 months after operation, and the lateral canthus brow tail line [ratio of lateral canthus to lateral end of eyebrow (LLE)]/LPF decreased ( P<0.05); HPF/CBH in the study group was lower than that in the young control group at 6 months after operation, but greater than that in the elderly control group ( P<0.05). Monthly HPF/LPF was significantly higher than that of the elderly control group ( P<0.05), and the LLE/LPF of the study group was significantly higher than that of the young control group at 6 months after operation ( P<0.05); intraoperative levator muscle shortening (LMS) was negatively correlated with postoperative MBH, CBH and LBH ( P<0.05), among which LMS had the greatest correlation with CBH ( r=-0.587). Conclusions:After ptosis correction, the palpebral fissures are larger, the distance between the eyebrows and the eyes is shortened, and there is a certain proportional relationship. After surgery, the patient's eyebrow-eye ratio is better than that of the elderly in the same age group, and it is closer to the young people, and the intraoperative LMS has a correlation with the eyebrow-eye distance, which can be used as a factor to predict the shortened distance of the eyebrow-eye distance.
RÉSUMÉ
Objective:To establish an HPLC method for the simultaneous determination of rutin, salvianolic acid B and ginsen-oside Rb1 in Xinning tablets. Methods:The samples were separated on a CAPCELL PAK MG(250 mm × 4. 6 mm,5μm)column with gradient elution using acetonitrile(A) and 0. 1％ phosphoric acid(B) as the mobile phase at a flow rate of 1. 0 ml·min-1. The col-umn temperature was set at 35℃. The wavelengths were set on 354nm, 286nm and 203 nm (in a wavelength switching mode). Re-sults:The linear range of rutin was 0. 0273-1. 3600 mg·ml-1(r =1. 0000), that of salvianolic acid B was 0. 0244-1. 2200 mg· ml-1(r=1.0000),and that of ginsenoside Rb1 was 0.0186-0.9310 mg·ml-1(r=0.9999), and the average recovery (n=6) was 102.3％ (RSD=1.1％),98.7％ (RSD=0.8％) and 101.7％ (RSD=1.8％)(n=6), respectively. Conclusion: A rapid, simple, accurate HPLC method is successfully established for the simultaneous determination of 3 effective components in Xinning tab-lets, which is helpful to the quality control of Xinning tablets.
