Background Refractive lens exchange is one of corrective surgeries for high myopic eyes and is concerned in clinic recently. Its clinical value is worthy of consideration. Objective This study was to investigate the efficacy and safety of refractive lens exchange for high myopic eyes. Methods Phacoemulsification and intraocular lens implantation was performed on 124 eyes of 65 patients with high myopia. The mean age of these patients was 51. 4±8. 57 years old,and the preoperative corrected visual acuity was 4. 11±0. 51. The mean spherical equivalent was ( -20. 17±5. 34) D. The mean axial length was (31. 33±2. 08) mm and intraocular lens power 2. 88 D. The follow-up time was 31 months. The uncorrective visual acuity, best corrective visual acuity, the spherical equivalent lens and complications were observed after operation. Written informed consent was obtained prior to the surgery. Results The uncorrective visual acuity improved after the operation in all the eyes. The uncorrective visual acuity was ≥0.5 in 15 eyes(12% ). The best corrected visual acuity improved in 114 eyes (92% ) following the surgery and that of 64 eyes (51. 6% ) was 2s 0. 5. The mean postoperative spherical equivalent was ( -2. 57 ± 1. 76 ) D in the entire follow-up duration. Posterior capsular opacification was found in 58 eyes (46. 7% ) and received laser capsulotomy. Retinal detachment occurred in 4 eyes throughout the follow-up period. Conclusion Refractive lens exchange is an effective and safe method for high myopic eyes. But preoperative fundus examination and long-term postoperative follow-up should be carried out to prevent the complications.

Objective:
To investigate psychosexual health of students during pubertal transition in Taizhou and explore the influence of family factors.
Methods:
A questionnaire survey was conducted among 1 215 students in senior grades of primary school, junior and senior high schools in Taizhou by stratified cluster sampling.
Results:
The average score of adolescents sexual and mental health questionnaire was (3.82±0.52), the sexual knowledge score was (3.31±1.00) and the score of sexual adaptation was (4.29±0.68). Sexual attitude and sexual control among female students were significantly better than male students (t=4.53,6.96,P<0.01). The four dimensions of physiological knowledge, sexual knowledge, sexual concept and self-adaptation made significant progress with the improvement increased with educational background(F=157.18,85.18,85.96,65.54,P<0.01). The parent-child relationship, parental sex education, the only child in the family, education background of parents, family economic status and the long-term separation from parents in early childhood had predictive effects on the development of puberty students’ psychosexual health (P<0.05).
Conclusion
Students during pubertal transition in Taizhou show moderate level of psychosexual health. Schools should strengthen sexual knowledge education.In order to promote students’ psychosexual health, more attention should be paid to the influence of family factors.
