CXCL10 Promotes Spinal Macrophage Recruitment via the JAK/STAT3 Pathway to Induce Pain in Experimental Autoimmune Prostatitis.

The aim is to explore the mechanisms underlying pain development in chronic prostatitis and identify therapeutic targets for pain management in patients with chronic prostatitis. RNA sequence of the spinal cord dorsal horns and proteomic analysis of spinal macrophages of experimental autoimmune prostatitis (EAP) mice were conducted to identify pain-related genes, proteins and signalling pathways. The clodronate liposome, CXCR3 and P-STAT3 inhibitors, NGF antibody and cromolyn sodium were used to investigate the roles of the CXCL10/CXCR3, JAK/STAT3 and NGF/TrKA pathways in spinal macrophage recruitment and pain response.

CXCR3 antagonist AMG487 ameliorates experimental autoimmune prostatitis by diminishing Th1 cell differentiation and inhibiting macrophage M1 phenotypic activation.

Background: Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS) is an inflammatory immune disease that is characterized by infiltrating inflammatory cells in the prostate and pelvic or by perineal pain. Receptor CXCR3modulates immune and inflammatory responses; however, the effects of CXCR3 antagonist AMG487 in the context of CP/CPPS are unknown. Therefore, we investigated the effect of AMG487 in experimental autoimmune prostatitis (EAP) mice and explored the potential functional mechanisms.

Identification of Novel Pyroptosis-Related Gene Signatures to Predict Prostate Cancer Recurrence.

Prostate cancer (PCa) is a common malignant type of urogenital tract tumor with poor prognosis. Despite therapeutic advances, the recurrence and mortality rates of PCa have continued to increase with poor prognoses. Pyroptosis, also known as inflammatory cell necrosis, is a recently identified type of programmed cell death that can regulate the invasiveness, differentiation, proliferation, and metastasis of tumor cells; thus, it has a profound effect on the prognosis of patients with tumors.

The purpose of the current research was to study the effect of melatonin on CP/CPPS and the underlying mechanisms using a mouse model of experimental autoimmune prostatitis (EAP).

Application of Contrast-Enhanced Ultrasonography (CEUS) in the Assessment of Kidney Wound Recovery After Nephron-Sparing Surgery.

Purpose: To investigate feasibility, repeatability and usefulness of contrast-enhanced ultrasonography (CEUS) in the assessment of kidney wound recovery after laparoscopic nephron-sparing surgery (LNSS) or robot-assisted nephron-sparing surgery (RANSS) and preliminarily research the clinical factors associated with the length of extravasation (LOE).
