ObjectiveTo observe the effects of vitrectomy for persistent fetal vasculature (PFV).Methods The clinical data of 11 patients (14 eyes) with PFV, including posterior PFV (one eye) and combined PFV (13 eyes), were retrospectively analyzed. Vitrectomy was performed for all patients,lensectomy was performed for seven eyes, retinotomy was performed for five eyes, retinotomy and scleral buckling was performed for one eye. Intraoperative and postoperative complications were observed. The follow-up period ranged from eight to 74 months, with the mean of 44 months. The visual acuity (VA) and intraocular pressure before and after surgery were comparatively analyzed. Results There were no intraoperative complications in all the patients. The surgery was performed successfully in 12 eyes (86.0 %)and failed in two eyes (14. 0%). The postoperative VA of five eyes (35.7%) increased, four eyes (28. 6%)didn't change and five eyes (35.7%) decreased. The postoperative intraocular pressure of two eyes (14. 3%) increased, 11 eyes (78. 6%) didn't change and one eye (7. 1%) decreased. There was one eye with persistent hypotension and one eye with recurrent retinal detachment after surgery. Conclusion Vitrectomy can prevent complications and improve visual acuity in some PFV patients.

Objective:To study the relationship between the expression of heat shock protein 27 (HSP27) in triple negative breast cancer (TNBC) and the clinico-pathological indexes of breast cancer, investigate the correlation between HSP27 and the fatty acid syn-thetase (FAS)/fatty acid synthetase ligand (FASL) of the cell apoptosis system in the Fas/Fasl system, and study the role of HSP27 in the invasion and metastasis of TNBC. Methods:The immunohistochemical S-P method was used to detect the expression of HSP27 and (FAS)/(FASL) in 100 TNBS tissue sampres, 100 non-TNBS tissue sampres, and 50 paraneoplastic tissues. This method was also used to analyze the correlations between the expression of HSP27 and the clinical and pathological indexes of TNBC, as well as be-tween the HSP27 expression and FAS/FASL expression. Results: HSP27 expression was significantly higher in TNBC than in the non-TNBC and paraneoplastic tissues (P<0.05). Statistically significant differences were observed in the FAS/FASL expression in the TNBC, non-TNBC, and paraneoplastic tissues (P<0.05). HSP27 expression had a negative correlation with FAS expression (P<0.05). HSP27 expression was positively correlated with FASL expression (P<0.05). FAS expression had a negative correlation with FASL ex-pression (P<0.05). HSP27 expression in TNBC was not correlated with age, staging, and tumor size (P>0.05), whereas HSP27 expres-sion was correlated with lymph node metastasis, number of nodal metastases, and P53 and Ki67 expression (P<0.05). Conclusion:The overexpression of HSP27 and the expression dysregulation of the FAS/FASL system may play a role in promoting TNBC transfer and invasion, cell proliferation, and poor prognosis.
