AIM: To evaluate the efficacy and safety of corneoscleral separation in the treatment of persistent corneal ulcer.METHODS: Collected 22 cases (22 eyes) with deep corneal ulcer were treated with drugs.These patients underwent corneoscleral separation or corneal interstitial filling of sterile gelatin sponge,by retrospectively observing the cornea ulcer healing,anterior chamber reaction and separation of new blood vessels grow between the layers,and so on,the surgical indications,surgical techniques,postoperative complications and treatment were evaluated.RESULTS: Patients were followed up 3 to 6mo,of which 18 eyes cornea were seen a small amount of new blood vessels,anterior chamber empyema after 7-9d.Ulcers gradually narrowed,infection controlled,the surrounding edema relieved,visual acuity improved by varying degrees after 12-15d.Postoperative 4 eyes for the mixed infection,2 of the 4 eyes were of the rapid progress,neovascularization did not grow into the lesion,ulcers on the verge of perforation and then done penetrating keratoplasty.CONCLUSION: The aim of this study is to introduce deep limbal vessels into the surrounding of ulcer foci,which to combine with drug therapy is one of the effective methods to treat deep corneal infection.

AIM:To investigate the changes of visual development produced by monocular atropinization in rats.
METHODS: Twenty normal SD rats were randomly divided into two groups: control group ( n = 10 ) and atropinization ( experimental) group ( n=10 ) . All the left eyes were selected as the experimental eyes, and the right eyes served as the normal eyes. The left eyes in atropinization group was produced by 1% atropine, 3 times a day and the right eyes in control group was treated with normal saline, 3 times a day. The flash visual evoked potentials ( F-VEP ) and retinoscopy refraction of the rats'both eyes were detected at five time points:0, 7, 14, 21, and 28d after atropinization, respectively. After 28d, six rats were randomly selected from both groups and each group had three rats. The expression of the c- fos mRNA was observed in both visual cortexes. Another six rats were chosen for the same test after 2d dark environment with 2h light later. The expression of c-fos mRNA was detected again.
RESULTS: After 14d anisometropia was observed in experimental group, the difference was 3. 9D ( P<
0.0 5 ) , F-VEP P1 wave of the rats left in experimental group was reached to 88. 9±1. 889ms at 21d, there was statistical difference compared with the right eye ( P<0.05). After 28d, c-fos mRNA expression in the left visual cortex of rats in the experimental group was higher than that of the right side, but there was no significant difference. But when underwent 2h light stimulation after in the darkroom 2d, the c-fos mRNA expression in in the left visual cortex of rats in the experimental group was 5 times higher than that of the right side, there was a statistically significant difference (P<0. 05).
CONCLUSION: In the critical period of visual development, monocular chronic atropine in rats can form anisometropia, may delay the transmission of the optic nerve, hinder the normal development of the visual cortex. Monocular atropinization in rats can be used as the model of anisometropia.

Objective The CYP19 gene product enzyme aromatase mediates the conversion of the androgen testosterone to es -tradiol.The aim of this study is to investigate whether the CYP19A1 gene single nucleotide polymorphism (SNP) is associated with the susceptibility to polycystic ovary syndrome (PCOS) and serum hormone levels. Methods We conducted a case-controlled study, which included 373 PCOS patients and 313 healthy controls.We genotyped SNP rs2899470 in the subjects using the polymerase chain re-action-restriction fragment length polymorphism ( PCR-RFLP) method and analyzed the frequencies of genotypes and alleles as well as the association of different genotypes with age , menarchal age, body mass index (BMI), and serum levels of hormones. Results The gen-otypic distributions of rs2899470 GG, TG, and TT in the PCOS women were 44.5%, 49.6%, and 5.9%, respectively, significantly dif-ferent from 39.3%, 48.6%, and 12.1%in the healthy controls (P=0.013).The frequency of the G allele was 69.3%in the former, remarkably higher than 63.6%in the latter (P=0.025).The rs2899470 genotypic frequencies were associated with the serum E 2/T lev-els in the PCOS patients. Conclusion SNP rs2899470 in the CYP19A1 gene is associated with the susceptibility to PCOS , and so is the genotype of rs2899470 with serum E2/T levels, which may be attributed mainly to the reduced activity of aromatase .
