Objective To study the morphological changes of external eyes before and after epicanthoplasty combined with blepharoplasty and to explore a simple and efficient method to correct epicanthus. Methods A total of 120 eyes in 60 patients were operated on with the inverted L-sharp epicanthoplasty combined with double-eyelid blepharoplasty and the follow-up began 2 months after the surgery. The height and physiognomic length of the eyelid and the length and angle of the eyelash were measured and compared with preoperative meansurements, as well as the distance of the inner canthus. The ratios between the inner-canthus distance and the physiognomic eyelid breadth and the diameter of eyebrow and eye were also described. Results The contours of the eyelid fissure and the double-eyelid were natural and the surgical scare was seen unconspicuous 3 months after the operation. Changes in the palpebral fissure , the angel and length of the exposed eyelash were all significantly different by paired-sample t test (P < 0.01). The vertical and horizontal lines through the entocanthion and the vertical line through the gnomic ectocanthion combined with the horizontal line through the brow ridge formed a square structure. Conclusions This inverted L-shape epicanthoplasty combined with blepharoplasty may be effective in reconstructing the contours of the entocanthions as well as the shape of the double eyelids. It can also achieve better cosmetic effects in the proportional relation between the eyes and eyebrows. Therefore, it deserves clinical promotion.

Objective:To investigate the cognitive status of the elderly in rural areas and explore the characteristics and influencing factors of subjective cognitive decline (SCD).Methods:A baseline survey was conducted among 5 765 rural elderly people aged 60 years old or above from March to September 2018.Subjective cognitive decline questionnaire(SCD-Q9), mini-mental state examination(MMSE), verbal fluency test (VFT), Chinese auditory verbal learning test (CAVLT), digital span test(DST)and activities of daily living(ADL)were used in the survey.The result of the survey indicated that there were 2 654 subjects with SCD (SCD group) and 1 008 subjects with normal cognitive function (NC group). Social support rating scale (SSRS) and short version of geriatric depression scale-15(GDS-15) were used to evaluate their psychosocial status.Descriptive analysis and Logistic regression analysis were conducted by SPSS 26.0 software.Results:(1) Compared with NC group, the SCD group had the following characteristics: delayed recognition rate(8.25 ±2.51), (12.38 ±2.53), reverse digit span (2.63±1.37), (3.69±1.45), social support (69.81±8.71), (64.40±9.44), GDS-15 (2.27±2.63), (1.31±2.17), and the differences were statistically significant (all P<0.05). However, there were no significant differences in the following characteristics: MMSE score (21.62±5.73), (21.47±5.84), speech fluency (27.80±7.35), (28.25±7.56), ADL score (20.70±1.35), (20.77±1.30), all P>0.05.(2) There were no significant differences in diet structure, blood glucose, blood lipid, cerebrovascular disease, diabetes, epilepsy and coronary heart disease between SCD group and NC group (all P>0.05). (3)SCD was mainly affected by age( β=0.06, OR=2.29, 95% CI=1.09-4.85), depression( β=-0.01, OR=2.96, 95% CI=0.68-4.94), hypertension( β=-0.17, OR=1.89, 95% CI=1.11-2.15), and low level of social support( β=2.07, OR=1.49, 95% CI=1.32-2.12) (all P<0.05). Conclusion:The scores of delayed recognition and reverse digit span in patients with SCD are lower than those with normal cognitive function.The other objective cognitive functions are basically normal.Old age, low social support level, depression, low education level and hypertension are the risk factors of SCD.

Objective To study the outcomes of selective reduction of triplet pregnancy by assisted reproductive technology. Methods The clinical data of 31 women who succeeded in conception by vitro fertilization-embryo transfer in the third affiliated hospital of Guangzhou Medical University were retrospectively investigated to analyze and compare the rates of abortion from triplet pregnancy, twin pregnancy and single pregnancy after selective reduction of triplet pregnancy, the incidence of pregnant complications, outcomes of perinatal period. Results There were no significant differences between triplet pregnancy and the twin and single pregnancy after selective reduction of triplet pregnancy in terms of pregnancy and parity time, fetal disease, premature rupture of membrane, severe eclampsism, gestational diabetes and postpartum hemorrhage (P>0.05). There were significant differences in gestational weeks, birth weight, rate of premature birth, rate of neonatal transfer to NICU and neonatal RDS: The gestational time in the triplet group longer than the groups of twin pregnancy and single pregnancy after selective reduction of triplet pregnancy (P<0.05). (37.3 ± 1.9) vs. (35.2 ± 0.9), (32.6 ± 2.3), respectively), the rate of premature birth dropped (100%vs. 100%, 33.3%, respectively), the body weight was increased (1 707 ± 360.4)g vs. (2 066.1 ± 307.5)g, (2 712.5 ± 514.1)g, respectively and the neonatal complication rate was reduced (P<0.05). Conclusion The selective reduction of multiple pregnancy may decrease the risk of premature birth and reduce the rate of lower body weight of neonates, improving the pregnancy outcomes, but the higher rate of abortion at the early or middle course of pregnancy after selective reduction is worth our attention.
