Objective:To study the expression and regulation of TLR2/4 in mycobacterium tuberculosis heat shock proteins 16. 3 (mycobacterium tuberculosis heat shock proteins 16. 3,MTB Hsp16. 3) effect on mouse bone marrow-derived macrophages in vitro. Methods:Bone marrow cells were isolated from tibia and femurs of BALB/c mice and incubated with GM-CSF,then detected the expression of CD11b and F4/80 with flow cytometry and observed morphology. The M0 macrophages were stimulated with MTB Hsp16. 3 for 0 h,12 h,24 h,36 h,48 h and 72 h. Real-time PCR detected the expression of TLR2/4 in intracellular at different time point. Silencing macrophages cell surface TLR2/4 molecules by siRNA technology which stimulated with MTB Hsp16. 3 for 0 h,12 h,24 h,36 h,48 h and 72 h. Real-time PCR detected the expression of TLR2/4,Ym-1,Fizz1,IL-10,TNF-α,iNOS and TGF-βin intracellular at different time point. Results:Morphology analysis showed that MTB Hsp16. 3 stimulated macrophages were round cells stretching out pseudopodia,whereas MTB Hsp16. 3 stimulated silencing TLR2/4 macrophages had elongated fibroblastoid. Real time PCR detected the expression of TLR2/4 were upregulated after MTB Hsp16. 3 stimulated M0 macrophages. MTB Hsp16. 3 stimulated silencing TLR2/4 macrophages the expression of IL-6, TNF-α, iNOS were upregulated, whereas IL-10, TGF-β, Ym-1 and Fizz1 were downregulated. Conclusion:MTB Hsp16. 3 may stimulated M0 macrophages to M2 macrophages and suppress M1 macrophages through binding with TLR2/4 receptor,which may be involved the progresss of MTB evaded macrophage phagocytosis.

One of the significant hurdles in telemedicine, particularly in ophthalmology, is the absence of direct physical examination. This specialty depends extensively on specialized instruments that typically require proficient operators. Visual function tests are crucial for both outpatient and inpatient ophthalmic services, playing a vital role in screening, diagnosing, monitoring treatment effectiveness, and managing follow-ups for various eye conditions. The progress in mobile technology has paved the way for expanding these tests beyond traditional clinic settings, promoting the creation of patient-focused, straightforward, cost-effective, and efficient measurement tools. In light of the swift advancement of digital technologies, this article reviews the characteristics, and reliability of self-administered visual function tests tools, including visual acuity, refractive error assessment, visual field, contrast sensitivity, and color vision, along with other pertinent diagnostic tools that have been developed and validated for accuracy and repeatability through research, with a view to providing ophthalmologists and patients with scientific and practical references when selecting and using these tools, further promoting efficiency and efficacy of teleophthalmology.
