Abstract
Along with a paradigm shift in looking at soft tissue fillers from space-filling to bioactive materials, decellularized extracellular matrix (DEM) fillers have gained more attention considering their superior bioactivity. However, the complex mechanisms that govern the interaction between host tissues and DEMs have been partially understood. This review first covers the mechanisms that determine immunogenicity, angiogenesis and vasculogenesis, and recellularization and remodeling after DEM implantation into host tissue, with a particular focus on related findings from filler materials. Accordingly, the review delves into the dual role of macrophages and their M1/M2 polarization paradigm to form both constructive and destructive immune responses to DEM implants. Moreover, the contribution of macrophages in angiogenesis has been elucidated, which includes but is not limited to the secretion of angiogenic growth factors and extracellular matrix (ECM) remodeling. The findings challenge the traditional view of immune cells as solely destructive entities in biomaterials and indicate their multifaceted roles in tissue regeneration. Furthermore, the review discusses how the compositional factors of DEMs, such as the presence of growth factors and matrikines, can influence angiogenesis, cell fate, and differentiation during the recellularization process. It is also shown that the biomechanical properties of DEMs, including tissue stiffness, modulate cell responses through mechanotransduction pathways, and the structural properties of DEMs, such as scaffold porosity, impact cell-cell and cell-ECM interactions. Finally, we pointed out the current clinical applications, the bottlenecks in the clinical translation of DEM biomaterials into soft tissue fillers, as well as the naïve research areas of the field.

Abstract
INTRODUCTION The extracellular matrix (ECM) plays an integral role in wound healing. It provides both structure and growth factors that allow for the organised cell proliferation. Large or complex tissue defects may compromise host ECM, creating an environment that is unfavourable for the recovery of anatomical function and appearance. Acellular dermal matrices (ADMs) have been developed from a variety of sources, including human (HADM), porcine (PADM) and bovine (BADM), with multiple different processing protocols. The objective of this report is to provide an overview of current literature assessing the clinical utility of ADMs across a broad spectrum of applications. METHODS PubMed, MEDLINE, EMBASE, Scopus, Cochrane and Web of Science were searched using keywords 'acellular dermal matrix', 'acellular dermal matrices' and brand names for commercially available ADMs. Our search was limited to English language articles published from 1999 to 2020 and focused on clinical data. RESULTS A total of 2443 records underwent screening. After removing non-clinical studies and correspondence, 222 were assessed for eligibility. Of these, 170 were included in our synthesis of the literature. While the earliest ADMs were used in severe burn injuries, usage has expanded to a number of surgical subspecialties and procedures, including orthopaedic surgery (e.g. tendon and ligament reconstructions), otolaryngology, oral surgery (e.g. treating gingival recession), abdominal wall surgery (e.g. hernia repair), plastic surgery (e.g. breast reconstruction and penile augmentation), and chronic wounds (e.g. diabetic ulcers). CONCLUSION Our understanding of ADM's clinical utility continues to evolve. More research is needed to determine which ADM has the best outcomes for each clinical scenario. LAY SUMMARY Large or complex wounds present unique reconstructive and healing challenges. In normal healing, the extracellular matrix (ECM) provides both structural and growth factors that allow tissue to regenerate in an organised fashion to close the wound. In difficult or large soft-tissue defects, however, the ECM is often compromised. Acellular dermal matrix (ADM) products have been developed to mimic the benefits of host ECM, allowing for improved outcomes in a variety of clinical scenarios. This review summarises the current clinical evidence regarding commercially available ADMs in a wide variety of clinical contexts.

Abstract
Post orgasmic illness syndrome is a rare, mysterious condition with an unknown pathomechanism and uncertain treatment. The symptoms of post orgasmic illness syndrome last about 2–7 days after an ejaculation. The current hypothesis proposes that the primary injury in post orgasmic illness syndrome is an acute compression proprioceptive axonopathy in the muscle spindle, as is suspected in delayed onset muscle soreness. The terminal arbor degeneration-like lesion of delayed onset muscle soreness is theorized to be an acute stress response energy-depleted dysfunctional mitochondria-induced impairment of Piezo2 channels and glutamate vesicular release. The recurring symptoms of post orgasmic illness syndrome after each ejaculation are suggested to be analogous to the repeated bout effect of delayed onset muscle soreness. However, there are differences in the pathomechanism, mostly attributed to the extent of secondary tissue damage and to the extent of spermidine depletion. The spermidine depletion-induced differences are as follows: modulation of the acute stress response, flu-like symptoms, opioid-like withdrawal and enhanced deregulation of the autonomic nervous system. The longitudinal dimension of delayed onset muscle soreness, in the form of post orgasmic illness syndrome and the repeated bout effect, have cognitive and memory consequences, since the primary injury is learning and memory-related.

Abstract
This study aimed to explore the efficacy of injection of micronised acellular dermal matrix (MADM) particles for treating primary premature ejaculation. This study was a prospective single-arm clinical trial. Thirty patients who met the surgical indications were enrolled. MADM particles, mixed in platelet-rich plasma, were injected into Buck's fascia to spread over the dorsal penile nerve, suppress the influx of nerve impulses and, thus, reduce penis sensitivity. We evaluated the changes according to intravaginal ejaculation latency time using a stopwatch and a premature ejaculation diagnostic tool. Meanwhile, we also recorded sexual partner satisfaction and adverse events. All patients recovered well after surgery with no complications such as infections or allergies. The mean intravaginal ejaculation latency time before surgery was 0.72 ± 0.28 min, compared with 2.41 ± 0.54 min, 2.64 ± 0.41 min, 2.79 ± 0.25 min and 2.89 ± 0.35 min at, respectively, 4, 8, 16 and 20 weeks after surgery. The premature ejaculation diagnostic values and sexual partner satisfaction had significantly improved after treatment. Injection of MADM particles is an effective, safe and simple method for treating premature ejaculation.

Abstract
Humanacellular dermal matrix (HADM) is widely used in the field of burn wound repair and tissue engineering plastic surgery. HADM is manufactored by physical and chemical decellular process to remove the antigenic components that might cause immune rejection in dermis.The extracellular matrix of three-dimensional cell scaffold structure with collagen fibers had been used for wound repair and tissue regeneration, while HADM characterized with low absorption rate after implantation and strong ability to induce angiogenesis in host tissue. Studies reported that after the HADM was implanted into the patient, the host cells, such as fibroblasts and myofibroblasts, as well as lymphocytes, macrophages, granulocytes and mast cells, rapidly infiltrated the graft. The connective tissue and neovascularization were then formed within the HADM three-dimensional cell scaffold, the lymphatic system also appears after vascular reconstruction. Traditional urethral reconstruction using autologous skin flaps has some defects, such as complexity of the technology, risk of necrosis of the skin flaps after transplantation, and failure to achieve functional repair of the urethral epithelium. It has been reported that using HADM to reconstruct the urethra in patients with urethral stricture, hypospadias and bladder-vaginal fistula, showed promising results. Others have reported the experience of using HADM to repair and reconstruct congenital classic bladder exstrophy. HADM has also been used for tissue repair in patients with penile skin defect caused by Fonier's gangrene and hidradenitis suppurativa, and implanted under Bucks' fascia to enlarge the penis. The report of HADM implantation for treating premature ejaculation also deserves attention. Researchers found that HADM implantation can form a tissue barrier between the skin and corpus cavernosum, which can effectively reduce penile sensitivity and treat premature ejaculation. The safety and effectiveness of HADM implantation in the treatment of premature ejaculation need to be further standardized by data from multi-center, large-sample clinical studies. In summary, HADM is the extracellular matrix and three-dimensional cell scaffold of human dermis. As a new type of tissue repair material, new blood vessels are formed actively after implantation, which shows good histocompatibility. HADM has shown increasingly broad application prospects in treatment of genitourinary diseases including penis, urethra and bladder diseases. HADM has also been used in the treatment of premature ejaculation in recent clinical studies, and its long-term safety and efficacy need to be further investigated.

Abstract
OBJECTIVE To investigate and analyze the complications of penile augmentation with acellular dermal matrix (ADM) and following management. METHODS This was a retrospective review of all patients who received penile augmentation with ADM between June 2016 and January 2019. The patients were evaluated with outpatient physical examination. Related complications and following management were summarized and analyzed. RESULTS Between June 2016 and January 2019, ADM was used as filling material on 78 patients (mean age: 31.14 years, range: 21-66 years), who were successfully received penile augmentation surgery. In the follow-up three months, the penile circumference was increased by 1.1 cm (0.5-2.1 cm) on average. The mean follow-up time was 12.20 months. In this study, there were 47 (60.26%, 47/78) patients with erectile discomfort, 91.49% (43/47) of whom manifested as erectile traction. There were 12 (15.38%, 12/78) patients with delayed healing, improved by daily regular dressing change. There were 10 (12.82%, 10/78) patients with unobvious augmentation effect. There were 9 (11.54%, 9/78) patients with stamp-like changes of ADM. There were 8 (10.26%, 8/78) patients with wound hematoma and 7 (8.97%, 7/78) patients with foreskin edema, relieved by compression with wrap. There were 4 (5.13%, 4/78) patients with wound infection and 3 (3.85%, 3/78) patients with skin necrosis of the dorsal side, which could be treated with ADM removal and repair surgery with bipedicle scrotal flap. And there were 2 (2.56%, 2/78) patients suffering psychological influence. Finally, most patients with various complications recovered successfully, however 7 patients (8.97%, 7/78) underwent ADM removal surgery. CONCLUSION Using ADM as filling material could achieve positive effect in penile augmentation but the complications are common and cannot be neglected. Standardized surgical methods, rigorous postoperative care, and adequate notification with patients can effectively reduce the complications of penile augmentation with ADM. To treat properly and timely for complications can obtain satisfactory results.
