Ilizarov technique for treating elbow stiffness caused by myositis ossificans: A case report.

Background: Myositis ossificans (MO) is a rare disease involving the formation of bone outside the musculoskeletal system. While surgical intervention is the main treatment approach, preventing recurrence and standardized rehabilitation are also crucial. Here, we present a surgical strategy to prevent the recurrence of MO.

The roles of long noncoding RNA-mediated macrophage polarization in respiratory diseases.

Macrophages play an essential role in maintaining the normal function of the innate and adaptive immune responses during host defence. Macrophages acquire diverse functional phenotypes in response to various microenvironmental stimuli, and are mainly classified into classically activated macrophages (M1) and alternatively activated macrophages (M2). Macrophage polarization participates in the inflammatory, fibrotic, and oncogenic processes of diverse respiratory diseases by changing phenotype and function.

Photodynamic-therapy Activates Immune Response by disrupting Immunity Homeostasis of Tumor Cells, which Generates Vaccine for Cancer Therapy.

Photodynamic therapy (PDT), a regulatory approved cancer treatment, is reported to be capable of causing immunogenic apoptosis. The current data reveal PDT can cause the dysregulation of "eat me" and "don't eat me" signal by generating reactive oxygen species (ROS) -mediated endoplasmic reticulum (ER) stress. This dysregulation probably contribute to the increased uptake of PDT-killed Lewis lung carcinoma (LLC) cells by homologous dendritic cells (DCs), accompanied by phenotypic maturation (CD80(high), CD86(high), and CD40(high)) and functional stimulation (NO(high), IL-10(absent)) of dendritic cells as well as subsequent T-cell responses.

Ganoderic acid Me induces the apoptosis of competent T cells and increases the proportion of Treg cells through enhancing the expression and activation of indoleamine 2,3-dioxygenase in mouse lewis lung cancer cells.

The indoleamine 2,3-dioxygenase-(IDO-) mediated microenvironment plays an important role in tumor immune escape. It is known that ganoderic acid Me can enhance IFN-γ expression and IDO is preferentially induced by IFN-γ. However, whether GA-Me can induce IDO expression has not been clarified yet.

Development of a multifunctional luciferase reporters system for assessing endoplasmic reticulum-targeting photosensitive compounds.

Photodynamic therapy (PDT) is a recently developed antitumor modality utilizing the generation of reactive oxygen species (ROS), through light irradiation of photosensitizers (PSs) localized in tumor. Interference with proper functioning of endoplasmic reticulum (ER) by ER-targeting PDT is a newly proposed strategy to achieve tumor cell death. The aim of this study is to establish a multifunctional model to screen and assess ER-targeting PSs based on luciferase reporters system.

Astragaloside IV inhibits progression of lung cancer by mediating immune function of Tregs and CTLs by interfering with IDO.

Purpose: Tumor cells have developed multiple mechanisms to escape immune recognition mediated by T cells. Indoleamine 2,3-dioxygenase (IDO), a tryptophan-catabolizing enzyme inducing immune tolerance, is involved in tumor escape from host immune systems in mice. Astragaloside IV (AS-IV), an extract from a commonly used Chinese medicinal plant Astragalus membranaceus, has been shown to be capable of restoring the impaired T-cell functions in cancer patients.

Hypericin-based Photodynamic Therapy Induces a Tumor-Specific Immune Response and an Effective DC-based cancer Immunotherapy.

In our study, we find that photodynamic therapy (PDT), which generates reactive oxygen species (ROS) -mediated endoplasmic reticulum (ER) stress to inflict trauma in the targeted lesion, can break the balance between membrane damage-associated molecular patterns (DAMPs) and integrin-associated protein (CD47). The imbalance undermines the ability of lewis lung carcinoma (LLC) cells to escape immune attack by increasing the uptake of hypericin-mediated PDT(hyp-PDT) killed lewis lung carcinoma (LLC) cells by homologous dendritic cells (DCs), accompanied by phenotypic maturation (CD80, CD86, and CD40) and functional stimulation (NO, IL-10) of dendritic cells as well as subsequent T-cell response. Besides, C57BL/6 mice vaccinated with dendritic cells (DCs) pulsed with PDT-treated LLCs (PDT-DCs) or PDT-treated LLCs alone (PDT-LLCs) show potent immunity against LLC tumor.

MiR-320a is downregulated in patients with myasthenia gravis and modulates inflammatory cytokines production by targeting mitogen-activated protein kinase 1.

Myasthenia gravis (MG) are T-cell dependent antibody-mediated autoimmune disorders, microRNAs are important regulators of human autoimmune disease pathogenesis. Here, we investigated the miRNAs expression profiles in MG for the first time and found that miR-320a was significantly downregulated in MG patients compared to normal healthy people. Meanwhile, pro-inflammatory cytokins in MG patients were overexpressed.
