Abstract: Upon monitoring cytoplasmic aberrant double-stranded DNA, cGAS-STING signaling pathway induces the expression of type I interferons and pro-inflammatory cytokines, which activates the host immune response and enhances anti-tumor immune response and resistance to pathogen infection. However, sustained activation of the cGAS-STING signaling pathway drives diseases such as autoimmune diseases, aging-associated inflammation, and neurodegenerative pathologies. Herein, we describe the mechanism by which cGAS-STING signaling pathway participates in regulating the development of various immune-related diseases, with a particular review of the research and development progress of STING agonists, cGAS inhibitors, and STING inhibitors, aiming to provide some theoretical reference for the future development of cGAS-STING modulators.

Bilateral vestibulopathy（BVP） is one of the common diseases in the vestibular nervous system, with an incidence rate of about 4%-7% in the population, which can lead to a variety of body dysfunctions. At present, there are two main treatment methods for BVP. One is vestibular rehabilitation. However, only part of BVP patients can finally benefit from vestibular rehabilitation, and most patients will remain with permanent vestibular dysfunction. Benefiting from the maturity of cochlear implant technology, European and American countries took the lead in the development of vestibular prosthesis（VP） technology to restore the vestibular function in patients with BVP. This review will focus on the development history, principles, future applications and the related research progress of VP in China.

Objective: To study the effect of a space stabilizing device on the capacity for osteogenesis in the bone-grafted area. Methods: Patients with anterior teeth defects as well as labial alveolar ridge defects were randomly divided into two groups: the experimental group was treated using a space stabilization device after guided bone regeneration whereas the control group received regular guided bone regeneration. The CBCT data was analyzed prior to, immediately and 6 months after procedure to compare the osteogenesis with or without the device. Results: Seventeen bone-grafted sites were examined(7 in the experimental group and 10 in the control group). At 2 mm and 4 mm below the alveolar ridge, the horizontal bone resorption rate in the experimental group was significantly lower than the corresponding level in the control group(P=0.001). The horizontal bone resorption rate at 2 mm below the alveolar ridge of each group was significantly higher than that at 4 mm below the alveolar ridge in corresponding groups(P=0.003). Conclusion The space stabilizing device used in this study has a positive clinical impact on preserving space stability and minimizing bone resorption.

A fundamental challenge that arises in biomedicine is the need to characterize compounds in a relevant cellular context in order to reveal potential on-target or off-target effects. Recently, the fast accumulation of gene transcriptional profiling data provides us an unprecedented opportunity to explore the protein targets of chemical compounds from the perspective of cell transcriptomics and RNA biology. Here, we propose a novel Siamese spectral-based graph convolutional network (SSGCN) model for inferring the protein targets of chemical compounds from gene transcriptional profiles. Although the gene signature of a compound perturbation only provides indirect clues of the interacting targets, and the biological networks under different experiment conditions further complicate the situation, the SSGCN model was successfully trained to learn from known compound-target pairs by uncovering the hidden correlations between compound perturbation profiles and gene knockdown profiles. On a benchmark set and a large time-split validation dataset, the model achieved higher target inference accuracy as compared to previous methods such as Connectivity Map. Further experimental validations of prediction results highlight the practical usefulness of SSGCN in either inferring the interacting targets of compound, or reversely, in finding novel inhibitors of a given target of interest.
