The 577 nm subthreshold micropulse laser(577 nm SML)is a non-invasive retinal laser treatment technique that selectively acts on the retinal pigment epithelium(RPE), induces heat shock protein expression, regulates inflammatory response, promotes blood retinal barrier repair, downregulates vascular endothelial growth factor(VEGF)levels, improves Müller cell function, promotes retinal metabolism and functional recovery, and avoids thermal damage caused by traditional threshold lasers. In recent years, 577 nm SML has been widely used in the treatment of various fundus diseases, including central serous chorioretinopathy(CSC), diabetes macular edema(DME), macular edema secondary to retinal vein occlusion(RVO-ME), age-related macular degeneration(ARMD), type 2 macular telangiectasia(MacTel2), persistent subretinal fluid after retinal detachment repair, and Irvine-Gass syndrome. Characterized by favorable safety and repeatability, 577 nm SML possesses high clinical application value and serves as a vital adjuvant and complementary strategy for anti-VEGF therapy. This review aims to summarize the therapeutic mechanisms and clinical applications of 577 nm SML in common fundus diseases, and provide a theoretical basis for its further clinical application.

AIM:To investigate the expression and function of store-operated calcium channels ( SOCC) in human circulating fibrocytes.METHODS:Peripheral blood mononuclear cells ( PBMCs) were isolated and cultured in ser-um-free media.After 7 d, the PBMCs differentiated into fibrocytes.RT-PCR and real-time PCR were performed to deter-mine the mRNA expression of ORAI1-3 and STIM1-2 in the fibrocytes.SOCC inhibitor SKF-96365 was used to elucidate the role of SOCC in the differentiation of fibrocytes.RESULTS:The results of real-time PCR showed that the mRNA ex-pression of ORAI1-3 and STIM1-2 was positive in cultured fibrocytes.SKF-96365 (10μmol/L) significantly inhibited the differentiation of fibrocytes.CONCLUSION:SOCC-related proteins ORAI1-3 and STIM1-2 are abundantly expressed in the fibrocytes, and may play an important role in the differentiation of these cells.

0.05). 73.96% of eczema were taken place at the age of 1～6 months, 13.02% were at the age of 6 months to 2 years, and 13.61% were at the age of 2～3 years. The incidence of eczema is also relevant to feeding patterns, which is 62.23%, 23.08% and 14.79% respectively by breast-feeding, mixed feeding and artificial feeding. Some other factors that relevant to the onset of eczema also have been found in the study, such as constitution, weather, genetic background, and so on. Conclusion Feeding pattern, genetic background and some other factors were relevant to the onset of eczema.
