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.

Objective To develop a new method for establishing a temperature gradient field in the microchannel on a glass-polydimethylsiloxane ( PDMS ) microfluidic chip and to verify its applicability in the study of cellular thermal biological effect.Methods The establishment and control of the temperature gradient field in the microchannel were implemented by a peripheral indium tin oxide ( ITO) heater and a heating micro-wire embedded in the PDMS chip.The temperature gradient field established in the microchannel was represented by the finite element numerical analysis and temperature-dependent fluorescent dye rhodamine B.Finally, the thermal biological effect, which used cell survival rate of human prostate cancer cells T24 as an indicator, was investigated in the microchannel.Results The results of finite element numerical analysis proved that this method established a temperature gradient field along the length of the microchannel successfully.The distribution range of the temperature gradient field was controlled by the ITO heater, while the gradient of the temperature gradient field was controlled by the heating micro-wire.The measurement result of rhodamine B was identical with the result of the finite element numerical analysis.The thermal biological effect of T24 tumor cell research showed that the cell survival rate decreased with the rise of the regional temperature in the microchannel.Conclusion The method developed in this paper for establishing a temperature gradient field in the microchannel on a glass-PDMS microfluidic chip is simple and easy to implement, and it can be used for parallel study of the cellular thermal biological effect on the microfluidic chip in the future.
