Objective:To observe the changes of vision and visual evoked potentials (VEP) in patients with Leber hereditary optic neuropathy (LHON) before and after gene therapy.Methods:A retrospective cohort study. From December 2017 to October 2018, 35 cases of 70 eyes of m11778G.A/MT-ND4 mutant LHON patients who were diagnosed in the Tongji Hospital of Huazhong University of Science and Technology and received gene therapy were included in the study. There were 30 males (87.71%) and 5 females (12.29%), with the mean age of 23.31±6.72 years. The gene therapy method was intravitreal injection of rAAV2-ND4 (recombinant adeno-associated virus carrying NADH-ubiquinone oxidoreductase subunit 4 gene) into one eye. The eye with poor visual acuity was chosen as the injection eye. If both eyes had the same visual acuity, the right eye was designated as the injection eye. Seventy eyes were divided into the injected eye group and the non-injected eye group, in which were both 35 eyes. The best corrected visual acuity (BCVA) and pattern VEP (PVEP) examinations were performed in the injected eye group and the non-injected eye group before treatment (baseline), 1, 3, and 6 months after injection. Compare the changes of BCVA and PVEP between the injected eye group and the non-injected eye group at baseline, 1 month, 3 months, and 6 months after injection. Independent sample t test, paired sample t test or two independent sample nonparametric test were performed to compare the two groups. Results:Compared with baseline, 1, 3, and 6 months after treatment, the BCVA of the injected eye group ( t=3.530, 4.962, 5.281; P=0.001, 0.000, 0.000) and the non-injected eye group ( t=3.288, 2.620, 2.252; P=0.002, 0.013, 0.031) increased, and the difference was statistically significant; there was no statistically significant difference between VEP IT ( tinjected eye group=-0.158, 1.046, -1.134; Pinjected eye group = 0.875, 0.303, 0.190; tnon-injected eye group=0.773, -0.607, -0.944; Pnon-injected eye group = 0.445, 0.548, 0.352) and VEP A ( Zinjected eye group=-0.504, -0.934, -1.065; Pinjected eye group = 0.614, 0.351, 0.287; Znon-injected eye group=-0.521, -0.115, -0.491; Pnon-injected eye group = 0.602, 0.909, 0.623). Conclusion:After gene therapy, the visual acuity of the injected and non-injected eyes of LHON patients improved; PVEP did not change significantly, and remained stable compared with baseline.

Background and purpose:The American College of Surgeons Oncology Group (ACOSOG) Z0011 trial has been described as practice-changing of sentinel lymph node (SLN) positive breast cancers. The goal of this study was to determine the exportability of the criteria deifned by Z0011 trial for selecting patients who are eligible for avoiding axillary lymph node dissection (ALND) after a positive sentinel lymph node biopsy (SLNB) result in China.Methods:We collected 194 breast cancer patients with positive SLNs and classiifed them into two groups according to Z0011 criteria. One group was consisted of patients who were eligible for omitting ALND and with SLNB only. The other one was ALND group. Then the patients of SLNB group were compared with cohort included in the Z0011 trial and the ALND group of this study separately.Results:Seventy-seven patients were potentially eligible for omitting ALND and 117 patients were still needed to have ALND. Compared with Z0011 cohort, the SLNB group in this research had signiifcantly more T1 stage and ER positive tumors (P<0.05). More patients in SLNB group had positive LNs with the number less than 3 and negative NSLNs (P<0.05). The ALND group had more T2 and T3 stage tumors than the SLNB group but the difference was not signiifcantly. The number of positive LNs in ALND group was higher than the SLNB group signiifcantly (P<0.05). More patients in the ALND group had positive non-sentinel lymph node (NSLN) than the SLNB group and the difference was also signiifcantly (P<0.05).Conclusion:Applied to the SLN positive patients in this study, Z0011 criteria could make patients with better prognosis and lower risk than Z0011 cohort be selected and let these patients avoiding ALND more safely.
