chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is an intractable aseptic disease. Modulating the transition of macrophages from the proinflammatory M1 phenotype to the anti-inflammatory M2 phenotype offers an attractive therapeutic approach. Recently, small extracellular vesicles (sEVs) derived from mesenchymal stem cells (MSCs) reportedly have potent modulatory abilities, however, their applications are limited by suboptimal targeting.

Currently available oral drug therapies exhibit limited efficacy in the treatment of CP/CPPS. Therefore, personalized and combination therapies are recommended by Chinese CP/CPPS guidelines, which primarily include traditional Chinese medicine, radiofrequency therapy, urethral lavage, transrectal prostate massage, extracorporeal shock wave therapy.

However, first-line treatment, represented by phosphodiesterase 5 inhibitors, is unable to maintain long-term efficacy. Extracellular vesicles (EVs) have recently attracted the attention of researchers in the fields of cardiovascular disease, neurologic disease, and regenerative medicine and may become a treatment for ED.

Aim: We aimed to explore the clinical value of AVSS with virtual reality (VR-AVSS) test in assessing erectile function and diagnosing erectile dysfunction (ED).
Methods: Participants 18 to 60 years of age were screened for analysis in 3 clinical centers from June 2020 to March 2022.
Hair follicle (HF) tissue engineering is promising for hair loss treatment especially for androgenetic alopecia. Physiologically, the initiation of HF morphogenesis relies on the interactions between hair germ mesenchymal and epithelial layers. To simulate this intricate process, in this study, a co-flowing microfluidic-assisted technology was developed to produce dual aqueous microdroplets capturing growth factors and double-layer cells for subsequent use in hair regeneration.

Background: Glycated serum albumin (GSA) is an early glycosylation product that participates in diabetic vascular complications. This study examined the role of GSA in early damage to the corpus cavernosum and the involved mechanisms.
Methods: Nine 8-week-old male Sprague-Dawley (SD) rats (250-300 g) were divided into the control (saline vehicle, n=3) and GSA (200 µg/kg, n=6) groups.
Cavernous nerve injury (CNI) is the leading cause of erectile dysfunction (ED) after radical prostatectomy and pelvic fracture. Transplantation of human adipose-derived stem cells (ASCs) has been widely used to restore erectile function in CNI-ED rats and patients. Umbilical cord blood-derived MSCs (CBMSCs) are similarly low immunogenic but much primitive compared to ASCs and more promising in large-scale commercial applications due to the extensive establishment of cord blood banks.

The elderly males undergo degenerative fertility and testicular endocrine function that jeopardize the reproductive health and well-being. However, the mechanisms underlying reproductive aging are unclear. Here, we tried to address this by investigating the phenotypes and transcriptomes of seven regions of the male mouse reproductive tract: the testis, efferent ductules, initial segment, caput, corpus and cauda epididymidis, and vas deferens, in adult (3 months) and aged (21 months) mice.

Although protective nerve technology has been widely used in nerve-sparing radical prostatectomy (nsRP), the incidence of ED is still very high after surgery. The purpose of our study was to evaluate erectile function (EF) and penile length in the non-erectile state (PLNES) following scheduled phosphodiesterase 5 inhibitor (PDE5i), vacuum erectile device (VED) treatment, and combination therapy after nsRP.

Methods: In this open multi-center case-control clinical trial, we enrolled 247 ED patients according to the designed criteria, and treated them orally with SHDG at 10 g per time tid (n = 74), TT at 5 mg per time bid (n = 52), or SHDG + TT at the above doses (n = 121), all for 8 weeks. Before and after medication, we recorded the IIEF-6, erection hardness scores (EHS), traditional Chinese medicine syndromes (TCMS) scores, penile cavernous blood flow parameters and adverse reactions, and compared them between the 3 groups of patients.

Here, we first simulated the conditions of ischemia and hypoxia using the oxygen-glucose deprivation (OGD) model and confirmed that hypoxic preconditioning of ASCs could provide improved protection against OGD and enhance ASC viability. Second, we assessed the effect of hypoxic preconditioning on pro-angiogenic potential of ASCs, with a particular focus on the role of vascular endothelial growth factor-A (VEGF-A) and stromal derived factor-1a (SDF-1a) paracrine activity in mediating angiogenesis.

Diabetic erectile dysfunction has witnessed extensive preclinical and clinical explorations of intracavernous injection of stem cells therapy. However, intracavernous injection of stem cells for diabetic erectile dysfunction is challenged by rapid diffusion from cavernous sinus. Here, we found that a benzaldehyde terminated poly (ethylene glycol)/glycol chitosan (CHO-PEG/GCS) hydrogel with injectability and self-healability served as a stem cell carrier to prolong cell retention in corpus cavernosum.

In this study, sponges with Janus character are developed using cellulose nanofibers (CNFs) that exhibit materials facets of different wettability characteristics using heterogeneous mixing and freeze-drying. The bonding of the interface between the hydrophilic and hydrophobic facets is achieved by using interpenetrating chemical cross-linking between CNFs and organosilanes.

The cytokines capable of promoting angiogenesis can improve vascular endothelial function, promote endothelial regeneration and thus improve erectile function, those capable of promoting nerve regeneration can improve erectile function by protecting cavernous nerves, those capable of protecting the smooth muscle function can improve erectile function by promoting the smooth muscle expression and inhibiting penile fibrosis, and those inflammation-related cytokines can induce penile erection by acting on the corresponding receptor relaxing smooth muscle. Compared with PDE-5 inhibitors, cytokines are more targeted for the treatment of ED.

CBAVD is mainly caused by mutations in the CFTR (cystic fibrosis transmembrane conductance regulator) gene and is also related to the X-linked ADGRG2 (adhesion G protein-coupled receptor G2) gene. Genetic screening and counseling strategies for Chinese CBAVD populations remain controversial because the genetic background of CBAVD in Chinese population is largely unknown.
