To evaluate the macular microstructure repair and explore the factors related to those changes and visual improvement after vitrectomy for idiopathic macular hole(IMH). Totally 19 eyes of 18 IMH patients who underwent macular hole(MH) surgery were evaluated with bestcorrected visual acuity(BCVA) and spectral-domain optical coherence tomography(SD-OCT) images. All 19 eyes closed at 6 mo postoperatively. BCVA was observed gradually improved(P<0.001), with subretinal fluid(SRF) gradually absorbed(P=0.021) and the rate of external limiting membrane(ELM) defects gradually decreased(P=0.011) with follow-up time. Poorer postoperative logMAR BCVA correlated with larger MH minimum diameter(P<0.001), larger MH basal diameter(P=0.008), longer symptom duration(P=0.002) and poorer preoperative logMAR BCVA(P=0.010). More improvement in BCVA correlated only with poorer preoperative in logMAR BCVA(P=0.002). The earlier reconstruction of ELM was associated with smaller MH basal diameter(P=0.022) and shorter symptom duration(P=0.008). In conclusion, smaller basal diameter of MH and shorter symptom duration were key factors in earlier reconstruction of ELM.

AIM: To investigate the regulation and mechanisms of periostin expression in retinal Müller glia, and to explore the relevance to retinal neovascularization. METHODS: The oxygen-induced retinopathy(OIR) mouse model and the human Moorfield/Institute of Ophthalmology-Müller 1(MIO-M1) cell line were used in the study. Immunofluorescence staining was used to determine the distribution and expression of periostin and a Müller glial cell marker glutamine synthetase(GS). Cytokines TNF-α and IFN-γ were added to stimulate the MIO-M1 cells. ShRNA was used to knockdown periostin expression in MIO-M1 cells. Quantitative real-time reverse transcription polymerase chain reaction(qRT-PCR) was conducted to assess the mRNA expression of periostin. RESULTS: Immunofluorescence staining showed that periostin was expressed by MIO-M1 Müller glia. GS-positive Müller glia and periostin increased in OIR retinas, and were partially overlaid. The stimulation of TNF-α and IFN-γ reduced the mRNA expression of periostin significantly and dose-dependently in MIO-M1 cells. Knockdown of periostin reduced mRNA expression of vascular endothelial growth factor A(VEGFA) in MIO-M1 cells, while VEGFA expression was not changed in periostin knock-out OIR retinas. CONCLUSION: Müller glia could be one of the main sources of periostin in the retina, and might contribute to the pathogenesis of retinal neovascularization. Proinflammatory cytokines TNF-α and IFN-γ attenuate the periostin expression in retinal Müller glia, which provides a potential and novel method in treating retinal neovascular diseases.

We described a new strategy to combine hybridization chain reaction(HCR) process and triplex DNA through Ag+/cysteine,thus to pursue the controllable process of HCR. H1, a specially-designed triplex DNA, with homopyrimidines which can bind to dsDNA through Hoogsteen bonding, forming a cap-like triplex DNA. The presence of Ag^+ can play the role as a H1 locker to stop initiator from triggering HCR process, forming Ag+-stabilized triplex DNA molecular switch(denoted as Ag^+-STDMS). However,the strong binding ability of cysteine towards Ag^+ forming stable Ag^+-cysteine can release the locking tail of H1 and realize the retriggering of HCR. This study presented a promising tool to regulate the self-assembly processes of DNA-based nanostructures in neutral environment. Under the optimum conditions, fluorescence intensity(peaking at 582 nm) of HCR is proportional to the concentration of Ag+ in the 0.2–4.0 μM range. Within the presence of Ag^+, the fluorescence intensity is also proportional to the concentration of cysteine in the 0.2–3.0 μM range. The method can successfully manipulate the assembly and disassembly of DNA in HCR.

Models of the coupling of electromagnetic and gravitational fields have been studied extensively for many years. In this paper,we consider the coupling between the Maxwell field and the Weyl tensor of the gravitational field to study how the wavevector of the electromagnetic wave is affected by a plane gravitational wave. We find that the wavevector depends upon the frequency and direction of polarization of the electromagnetic waves, the parameter that couples the Maxwell field and the Weyl tensor, and the angle between the direction of propagation of the electromagnetic wave and the coordinate axis. The results show that this coupling model can be tested by the detection of high-frequency gravitational waves.
