Abstract
In comparison to other commercially used lasers, the coagulation layer of the novel 450-nm laser is thinner, and this coagulation layer's thickness is a key factor influencing wound healing. In this study, we investigated whether the novel 200W 450-nm laser system (BR6800, Blueray Medical Ltd., Shaanxi, China) is superior to classic transurethral resection of the prostate (TURP) for wound healing in beagles. Twenty-two 6-to 8-year-old male beagles were treated with TURP or blue laser vaporization of the prostate (BLVP). Prostate wounds were observed via cystoscopy at 3 h and at 1, 2, 3, and 5 weeks post-operation (two beagles per group). Additionally, two elderly beagles without surgery served as normal controls. After cystoscopy examination, prostate samples were collected and fixed for hematoxylin and eosin (H&E) and immunofluorescence staining to observe wound healing progression under microscopy. The urethras of prostates under cystoscopy in BLVP groups were healed three weeks after surgery, while in the TURP group, they were healed five weeks after surgery. H&E staining confirmed that the coagulation necrosis layer in the TURP group was thicker than that in the BLVP group and it took longer to remove coagulation necrosis after surgery. Macrophage polarity transformation was also earlier in the BLVP group. The new 200W 450-nm laser was superior to TURP for wound healing. The thinner coagulation layer of the 450-nm laser was the primary reason for this process.

Abstract
The synovial tissue is an immunologically challenging environment where, under homeostatic conditions, highly specialized subsets of immune-regulatory macrophages and fibroblasts constantly prevent synovial inflammation in response to cartilage- and synovial fluid-derived danger signals that accumulate in response to mechanical stress. During inflammatory joint diseases, this immune-regulatory environment becomes perturbed and activated synovial fibroblasts and infiltrating immune cells start to contribute to synovial inflammation and joint destruction. This review summarizes our current understanding of the phenotypic and molecular characteristics of resident synovial macrophages and fibroblasts and highlights their crosstalk during joint homeostasis and joint inflammation, which is increasingly appreciated as vital to understand the molecular basis of prevalent inflammatory joint diseases such as rheumatoid arthritis.

Abstract
BACKGROUND This study investigated shallow heat injury to prostate stromal fibroblasts and epithelial cells and their interaction to regulate the wound healing and the underlying molecular events. METHODS Prostate stromal fibroblasts and epithelial cells were cultured individually or cocultured and subjected to shallow heat injury for assessments of cell proliferation, migration, apoptosis, cell cycle distribution, and gene expression. The supernatant of heat-injured WPMY-1 cells was collected for exosome extraction and assessments. Furthermore, beagle dogs received thulium laser resection of the prostate (TmLRP) and randomly divided into Gefitinib, GW4869, and control treatment for the histological analysis, tissue re-epithelialization, and epidermal growth factor receptor (EGFR) expression on the prostatic wound surface. Immunofluorescence was to evaluate p63-positive basal progenitor cell trans-differentiation and macrophage polarization and ELISA was to detect cytokine levels in beagles' urine. RESULTS Shallow heat injury caused these cells to enter a stressed state and enhanced their crosstalk. The prostate stromal fibroblasts produced and secreted more exosomal-EGFR and other cytokines and chemokines after shallow heat injury, resulting in increased proliferation and migration of prostate epithelial cells during wound healing. The wound healing of the canine prostatic urethra following the TmLRP procedure was slower in the Gefitinib and GW4869 treatment group than in the control group of animals. Immunofluorescence and ELISA showed that reduced EGFR expression interrupted macrophage polarization but increased the inflammatory response. CONCLUSIONS Shallow heat injury was able to promote the interaction of prostate stromal cells with prostate epithelial cells to enhance wound healing. Stromal-derived exosomal-EGFR plays a crucial role in the balance of the macrophage polarization and prostatic wound healing.

Porous Se@SiO 2 nanosphere-coated catheter accelerates prostatic urethra wound healing by modulating macrophage polarization through reactive oxygen species-NF-κB pathway inhibition.

Abstract
Benign prostatic hyperplasia (BPH) patients experience complications after surgery. We studied oxidative stress scavenging by porous Se@SiO2 nanospheres in prostatic urethra wound healing after transurethral resection of the prostate (TURP). Beagle dogs were randomly distributed into two groups after establishing TURP models. Wound recovery and oxidative stress levels were evaluated. Re-epithelialization and the macrophage distribution at the wound site were assessed by histology. The mechanism by which porous Se@SiO2 nanospheres regulated macrophage polarization was investigated by qRT-PCR, western blotting, flow cytometry, immunofluorescence and dual luciferase reporter gene assays. Our results demonstrated that Porous Se@SiO2 nanosphere-coated catheters advance re-epithelization of the prostatic urethra, accelerating wound healing in beagle dogs after TURP, and improve the antioxidant capacity to inhibit oxidative stress and induced an M2 phenotype transition of macrophages at the wound. By restraining the function of reactive oxygen species (ROS), porous Se@SiO2 nanospheres downregulated Ikk, IκB and p65 phosphorylation to block the downstream NF-κB pathway in macrophages in vitro. Since activation of NF-κB signaling cascades drives macrophage polarization, porous Se@SiO2 nanospheres promoted macrophage phenotype conversion from M1 to M2. Our findings suggest that porous Se@SiO2 nanosphere-coated catheters promote postoperative wound recovery in the prostatic urethra by promoting macrophage polarization toward the M2 phenotype through suppression of the ROS-NF-κB pathway, attenuating the inflammatory response. STATEMENT OF SIGNIFICANCE: The inability to effectively control post-operative inflammatory responses after surgical treatment of benign prostatic hyperplasia (BPH) remains a challenge to researchers and surgeons, as it can lead to indirect cell death and ultimately delay wound healing. Macrophages at the wound site work as pivotal regulators of local inflammatory response. Here, we designed and produced a new type of catheter with a coating of porous Se@SiO2 nanosphere and demonstrated its role in promoting prostatic urethra wound repair by shifting macrophage polarization toward the anti-inflammatory M2 phenotype via suppressing ROS-NF-κB pathway. These results indicate that the use of porous Se@SiO2 nanosphere-coated catheter may provide a therapeutic strategy for postoperative complications during prostatic urethra wound healing to improve patient quality of life.

Abstract
Macrophages play a crucial role in regeneration and consecutive phases of wound healing. In this review, we summarise current knowledge on the ontogeny, origin, phenotypical heterogeneity, and functional exchangeability of macrophages participating in these processes. We also describe the genetic, pharmacologic, and bioengineering methods for manipulation of macrophage phenotype and functions and their potential for development of the novel, clinically applicable therapies.
