Zhu S, Xiong Y, Yu B, Wang H, Zhang F, Wu C, Qin F, Yuan J. Vitamin D3 improved erectile function recovery by regulating autophagy and apoptosis in a rat model of cavernous nerve injury. Int J Impot Res 2024; 36:430-436. [PMID: 36813836 DOI: 10.1038/s41443-023-00679-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 02/01/2023] [Accepted: 02/03/2023] [Indexed: 02/24/2023]
Abstract
Vitamin D3 is an important element in improving erectile function. However, the mechanisms of vitamin D3 remain unknown. Thus, we explored the effect of vitamin D3 on erectile function recovery after nerve injury in a rat model and investigated its possible molecular mechanisms. Eighteen male Sprague-Dawley rats were used in this study. The rats were randomly divided into three groups: the control, bilateral cavernous nerve crush (BCNC), and BCNC + vitamin D3 groups. BCNC model was established in rats by surgery. The intracavernosal pressure and the ratio of intracavernosal pressure to mean arterial pressure were utilized to evaluate erectile function. Masson trichrome staining, immunohistochemistry, terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling and western blot analysis were performed on penile tissues to elucidate the molecular mechanism. The results indicated that vitamin D3 alleviated hypoxia and suppressed the fibrosis signalling pathway by upregulating the expression of eNOS (p = 0.001), nNOS (p = 0.018) and α-SMA (p = 0.025) and downregulating the expression of HIF-1α (p = 0.048) and TGF-β1 (p = 0.034) in BCNC rats. Vitamin D3 promoted erectile function restoration by enhancing the autophagy process through decreases in the p-mTOR/mTOR ratio (p = 0.02) and p62 (p = 0.001) expression and increases in Beclin1 expression (p = 0.001) and the LC3B/LC3A ratio (p = 0.041). Vitamin D3 application improved erectile function rehabilitation by suppressing the apoptotic process through decreases in the expression of Bax (p = 0.002) and caspase-3 (p = 0.046) and an increase in the expression of Bcl2 (p = 0.004). Therefore, We concluded that vitamin D3 improved the erectile function recovery in BCNC rats by alleviating hypoxia and fibrosis, enhancing autophagy and inhibiting apoptosis in the corpus cavernosum.

Abstract
Previous reports have established that rESWT fosters angiogenesis, yet the mechanism by which rESWT promotes cerebral angiogenesis remains elusive. rESWT stimulated HUVECs proliferation as evidenced by the CCK-8 test, with an optimal dosage of 2.0 Bar, 200 impulses, and 2 Hz. The tube formation assay of HUVECs revealed that tube formation peaked at 36 h post-rESWT treatment, concurrent with the lowest expression level of Bach1, as detected by both Western blot and immunofluorescence. The expression level of Wnt3a, β-catenin, and VEGF also peaked at 36 h. A Bach1 overexpression plasmid was transfected into HUVECs, resulting in a decreased expression level of Wnt3a, β-catenin, and VEGF. Upon treatment with rESWT, the down-regulation of Wnt3a, β-catenin, and VEGF expression in the transfected cells was reversed. The Wnt/β-catenin inhibitor DKK-1 was utilized to suppress Wnt3a and β-catenin expression, which led to a concurrent decrease in VEGF expression. However, rESWT treatment could restore the expression of these three proteins, even in the presence of DKK-1. Moreover, in the established OGD model, it was observed that rESWT could inhibit the overexpression of Bach1 and enhance VEGF and VEGFR-2 expression under the OGD environment.

Low-Intensity Extracorporeal Shock Wave Therapy Ameliorates Detrusor Hyperactivity with Impaired Contractility via Transient Potential Vanilloid Channels: A Rat Model for Ovarian Hormone Deficiency. Int J Mol Sci 2024; 25:4927. [PMID: 38732143 PMCID: PMC11084446 DOI: 10.3390/ijms25094927] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Revised: 04/18/2024] [Accepted: 04/24/2024] [Indexed: 05/13/2024] Open
Abstract
This study explores low-intensity extracorporeal shock wave therapy (LiESWT)'s efficacy in alleviating detrusor hyperactivity with impaired contractility (DHIC) induced by ovarian hormone deficiency (OHD) in ovariectomized rats. The rats were categorized into the following four groups: sham group; OVX group, subjected to bilateral ovariectomy (OVX) for 12 months to induce OHD; OVX + SW4 group, underwent OHD for 12 months followed by 4 weeks of weekly LiESWT; and OVX + SW8 group, underwent OHD for 12 months followed by 8 weeks of weekly LiESWT. Cystometrogram studies and voiding behavior tracing were used to identify the symptoms of DHIC. Muscle strip contractility was evaluated through electrical-field, carbachol, ATP, and KCl stimulations. Western blot and immunofluorescence analyses were performed to assess the expressions of various markers related to bladder dysfunction. The OVX rats exhibited significant bladder deterioration and overactivity, alleviated by LiESWT. LiESWT modified transient receptor potential vanilloid (TRPV) channel expression, regulating calcium concentration and enhancing bladder capacity. It also elevated endoplasmic reticulum (ER) stress proteins, influencing ER-related Ca2+ channels and receptors to modulate detrusor muscle contractility. OHD after 12 months led to neuronal degeneration and reduced TRPV1 and TRPV4 channel activation. LiESWT demonstrated potential in enhancing angiogenic remodeling, neurogenesis, and receptor response, ameliorating DHIC via TRPV channels and cellular signaling in the OHD-induced DHIC rat model.

Efficacy of low-intensity shockwave therapy with different tadalafil regimens in patients with PDE5 inhibitor-resistant erectile dysfunction: a retrospective cohort study. Int Urol Nephrol 2024; 56:407-413. [PMID: 37751053 DOI: 10.1007/s11255-023-03769-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Accepted: 08/23/2023] [Indexed: 09/27/2023]
Abstract
PURPOSE Currently, there is a lack of research comparing tadalafil treatment protocols recommended during low-intensity shock wave therapy (LI-SWT) for patients with erectile dysfunction (ED) who are unresponsive to phosphodiesterase type 5 inhibitors (PDE5i). The objective of this study is to compare the efficacy of only LI-SWT versus LI-SWT plus 5 mg tadalafil daily versus LI-SWT plus 20 mg tadalafil alternate-day in PDE5i -resistant ED. MATERıALS AND METHODS: In this study, a cohort of 105 patients with PDE5i-resistant ED was recruited and divided into three groups labeled as A (only LI-SWT), B (LI-SWT plus 5 mg tadalafil daily), and C (LI-SWT plus 20 mg tadalafil alternate-day), comprising 27, 42, and 36 patients, respectively. The patients' International Index of Erectile Function-5 (IIEF-5) scores and the Erection Hardness Score (EHS) were evaluated at the baseline, three months and six months following the treatment. RESULTS After three months post-treatment, the IIEF-5 scores in group A, B, and C increased by 4.1 ± 0.6, 7.3 ± 0.6, and 8.2 ± 0.6, respectively. These improvements were maintained at six months with IIEF-5 scores increasing by 3.7 ± 0.6, 7.3 ± 0.6, and 8.5 ± 0.7 in groups A, B, and C, respectively. At 3 and 6 months post-treatment, groups B and C showed significant improvement in IIEF-5 scores and EHS values compared to group A (p < 0.001). The rate of patients with EHS ≥ 3 and IIEF-5 ≥ 17 was significantly higher in groups B and C compared to group A, while there was no significantly different between groups B and C. CONCLUSıON: In patients with PDE5i-resistant ED, PDE5i combined with LI-SWT is superior to LI-SWT monotherapy. The statistical analysis failed to demonstrate any difference between two distinct tadalafil regimens when administered with LI-SWT treatment.

Abstract
Autophagy is a lysosomal degradation process known as autophagic flux, involving the engulfment of damaged proteins and organelles by double-membrane autophagosomes. It comprises microautophagy, chaperone-mediated autophagy (CMA), and macroautophagy. Macroautophagy consists of three stages: induction, autophagosome formation, and autolysosome formation. Atg8-family proteins are valuable for tracking autophagic structures and have been widely utilized for monitoring autophagy. The conversion of LC3 to its lipidated form, LC3-II, served as an indicator of autophagy. Autophagy is implicated in human pathophysiology, such as neurodegeneration, cancer, and immune disorders. Moreover, autophagy impacts urological diseases, such as interstitial cystitis /bladder pain syndrome (IC/BPS), ketamine-induced ulcerative cystitis (KIC), chemotherapy-induced cystitis (CIC), radiation cystitis (RC), erectile dysfunction (ED), bladder outlet obstruction (BOO), prostate cancer, bladder cancer, renal cancer, testicular cancer, and penile cancer. Autophagy plays a dual role in the management of urologic diseases, and the identification of potential biomarkers associated with autophagy is a crucial step towards a deeper understanding of its role in these diseases. Methods for monitoring autophagy include TEM, Western blot, immunofluorescence, flow cytometry, and genetic tools. Autophagosome and autolysosome structures are discerned via TEM. Western blot, immunofluorescence, northern blot, and RT-PCR assess protein/mRNA levels. Luciferase assay tracks flux; GFP-LC3 transgenic mice aid study. Knockdown methods (miRNA and RNAi) offer insights. This article extensively examines autophagy's molecular mechanism, pharmacological regulation, and therapeutic application involvement in urological diseases.

Abstract
Autophagy is a highly conserved, lysosome-dependent biological mechanism involved in the degradation and recycling of cellular components. There is growing evidence that autophagy is related to male reproductive biology, particularly spermatogenic and endocrinologic processes closely associated with male sexual and reproductive health. In recent decades, problems such as decreasing sperm count, erectile dysfunction, and infertility have worsened. In addition, reproductive health is closely related to overall health and comorbidity in aging men. In this review, we will outline the role of autophagy as a new player in aging male reproductive dysfunction and prostate cancer. We first provide an overview of the mechanisms of autophagy and its role in regulating male reproductive cells. We then focus on the link between autophagy and aging-related diseases. This is followed by a discussion of therapeutic strategies targeting autophagy before we end with limitations of current studies and suggestions for future developments in the field.

Abstract
Vascular endothelial is considered to be a key factor in the pathogenesis of erectile dysfunction (ED). The purpose is to reveal the research trend of the field of ED and vascular endothelium. In addition, the goal is to discover the role and mechanism of vascular endothelium in ED. Bibliometrics and visualization methods based on CiteSpace were selected. We conducted the co-authorship analysis of countries, institutions and authors, co-occurrence analysis of keywords, and co-citation analysis of literature and authors through CiteSpace 6.1.R3. 1431 articles from Web of Science Core Collection (WOSCC) were included in the analysis from 1991 to 2022. We found some influential and cutting-edge nodes in each map, including countries, institutions, authors, articles, etc. Stem cell, therapy, oxidative stress, cavernous nerve injury, radical prostatectomy, fibrosis, erectile function, mesenchymal stem cell, and apoptosis may be hot keywords. In conclusion, the efficacy and mechanisms of stem cells and their derivatives in the treatment of diabetes (DM) ED and cavernous nerve injury (CNI) ED are the future research trends. Stem cells therapy for ED is a hot spot in this field, which side notes that stem cells may work mainly through improving endothelial function. Vascular endothelial cells and VEGF may repair nerve and cavernous smooth muscle directly or indirectly, and finally polish up erectile function.

Abstract
BACKGROUND Erectile dysfunction (ED) is a very common complication in men with diabetes mellitus (DM). Low-intensity extracorporeal shockwave therapy (Li-ESWT) offers a promising nonsurgical treatment option for ED. A systematic scoping review investigating the outcomes of Li-ESWT in diabetic men with ED has not yet been performed. OBJECTIVES To systematically review animal and clinical studies related to the use of Li-ESWT for treatment of DM-related ED. DATA SOURCES PubMed, Embase, The Cochrane Library, Scopus, and Web of Science were searched, unrestricted by dates or study design. MATERIALS AND METHODS We included qualitative studies, quantitative studies, primary research studies, meta-analyses, and research letters written in English. Full text reviewing was completed in all animal and human studies discussing Li-ESWT for the treatment of ED in subjects with DM. Data extracted included the journal citation, publication year, country of origin, study design, and a summary of the pertinent findings. RESULTS Our search yielded nine clinical studies and 10 animal studies. The results of the clinical studies suggest that Li-ESWT is a safe and effective treatment in men with well-controlled DM and moderate or better ED. However, the benefit is less durable in diabetic men than nondiabetic men. The results of the animal studies suggest that Li-ESWT can significantly improve erectile function in diabetic rat models with ED. CONCLUSIONS The examined studies present encouraging results for the use of Li-ESWT to treat diabetic men with ED. Future studies, particularly robust randomized controlled trials, are necessary to confirm these findings and provide long-term follow-up.

Methods DMED was induced in the experimental rats [male 12-week-old Sprague-Dawley (SD) rats] by treatment with streptozotocin (60 mg/kg) and apomorphine (APO). Next, rats in the GLP low dose (GLP-L)/GLP high dose (GLP-H) groups were treated with GLP (100 or 400 mg/kg/d, respectively) for 8 weeks. Subsequently, erectile function was assessed by APO and electrostimulation of the cavernous nerve (CN). Serum or penile testosterone (T), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and cyclic guanosine monophosphate (cGMP) contents were evaluated by enzyme-linked immunosorbent assay (ELISA). The levels of oxidative stress indicators in the corpus cavernosum (CC) were measured by corresponding kits, and histological changes in the CC were observed by hematoxylin-eosin (HE) and Masson staining. Additionally, the apoptosis index, caspase-3, caspase-9, and eNOS expression, and mitochondrial membrane potential (MMP) were also detected. Furthermore, quantitative polymerase chain reaction (qPCR) and western blot assays were conducted to determine the NOS, TGF-β1 mRNA expression, ERK1/2, eNOS, JNK phosphorylation, and arginase II protein expression. Results The erectile function test revealed that erectile dysfunction (ED) was alleviated in the DMED rats following treatment with GLP. Moreover, GLP upregulated the T and cGMP content, improved the oxidative stress and histological injuries of CC, and also inhibited the apoptosis and MMP loss of penile tissues in DMED rats. Furthermore, GLP treatment enhanced the mRNA expression of NOS and TGF-β1 and suppressed the phosphorylation of ERK1/2, eNOS, and JNK, as well as the protein expression of arginase II in DMED rats. Conclusions GLP ameliorated DMED by repairing the CC pathological damage and upregulating NOS expression and ERK/JNK phosphorylation, indicating that GLP may be a candidate drug for DMED therapy.

N-acetylcysteine improves diabetic associated erectile dysfunction in streptozotocin-induced diabetic mice by inhibiting oxidative stress. J Cell Mol Med 2022; 26:3527-3537.

Abstract
Oxidative stress appears to play a role in the pathogenesis of diabetes mellitus erectile dysfunction (DMED). This study aimed to investigate the effect of N‐acetylcysteine (NAC) on DMED in streptozotocin‐induced diabetic mice and to explore potential mechanisms. In the present study, we show that an erectile dysfunction is present in the streptozotocin‐induced mouse model of diabetes as indicated by decreases in intracavernous pressure responses to electro‐stimulation as well as from results of the apomorphine test of erectile function. After treatment of NAC, the intracavernous pressure was increased. In these DMED mice, oxidative stress and inflammatory responses were significantly reduced within the cavernous microenvironment, while activity of antioxidant enzymes in this cavernous tissue was enhanced after NAC treatment. These changes protected mitochondrial stress damage and a significant decreased in apoptosis within the cavernous tissue of DMED mice. This appears to involve activation of the nuclear factor erythroid 2‐like‐2 (Nrf2) signalling pathway, as well as suppression of the mitogen‐activated protein kinase (MAPK) p38/ NF‐κB pathway within cavernous tissue. In conclusion, NAC can improve erectile function through inhibiting oxidative stress via activating Nrf2 pathways and reducing apoptosis in streptozotocin‐induced diabetic mice. NAC might provide a promising therapeutic strategy for individuals with DMED.

Abstract
The present study aimed to assess the value of human umbilical cord mesenchymal stem cells (hUC-MSCs) for the treatment of diabetes-induced erectile dysfunction (DMED). We established a type 1 diabetes model through intra-abdominal streptozotocin injection. After 10 weeks, an apomorphine test was performed to screen the rats for erectile dysfunction (ED). The rats were divided into three groups: normal control group (n = 10), DMED group (n = 9) and DMED+hUC-MSC group (n = 9). After 4 weeks of hUC-MSC therapy, erectile function was evaluated by intracavernous pressure measurements, and penile tissue collagen and smooth muscle were examined by haematoxylin-eosin and Masson's trichrome staining. In addition, western blotting, immunohistochemistry and RT-PCR analysis of TLR4, VEGF and eNOS were performed. The results showed that hUC-MSC treatment restored erectile function (p < .05) and reversed the smooth muscle/collagen ratio changes of DMED rats (p < .05). Furthermore, hUC-MSC treatment inhibited the expression of TLR4 (p < .05) and enhanced VEGF and eNOS expression (p < .05). In conclusion, hUC-MSC treatment restored the erectile function of diabetic rats by inhibiting TLR4, improving corpora cavernosa fibrosis, and increasing VEGF and eNOS expression.

Abstract
Background Loss of function of key autophagy genes are associated with a variety of diseases. However specific role of autophagy-related genes in erectile dysfunction ED remains unclear. This study explores the autophagy-related differentially expressed genes (ARGs) profiles and related molecular mechanisms in Corpus Cavernosum endothelial dysfunction, which is a leading cause of ED. Methods The Gene Expression Omnibus (GEO) database was used to identify the key genes and pathways. Differentially expressed genes (DEGs) were mined using the limma package in R language. Next, ARGs were obtained by matching DEGs and autophagy-related genes from GeneCard using Venn diagrams. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses of ARGs were described using clusterProfiler and org.Hs.eg.db in R. Moreover, hub ARGs were screened out through protein-protein interaction (PPI), gene-microRNAs, and gene-transcription factors (TFs) networks then visualized using Cytoscape. Of note, the rat model of diabetic ED was established to validate some hub ARGs with qRT-PCR and Western blots. Results Twenty ARGs were identified from four ED samples and eight non-ED samples. GO analysis revealed that molecular functions (MF) of upregulated ARGs were mainly enriched in nuclear receptor activity. Also, MF of downregulated ARGs were mainly enriched in oxidoreductase activity, acting on NAD(P)H and heme proteins as acceptors. Moreover, six hub ARGs were identified by setting high degrees in the network. Additionally, hsa-mir-24-3p and hsa-mir-335-5p might play a central role in several ARGs regulation, and the transcription factors-hub genes network was centered with 13 ARGs. The experimental results further showed that the expression of Notch1, NOS3, and CDKN2A in the diabetic ED group was downregulated compared to the control. Conclusions Our study deepens the autophagy-related mechanistic understanding of endothelial dysfunction of ED. NOTCH1, CDKN2A, and NOS3 are involved in the regulation of endothelial dysfunction and may be potential therapeutic targets for ED by modulating autophagy.

Abstract
Postmenopausal women with ovary hormone deficiency (OHD) are subject to overactive bladder (OAB) symptoms. The present study attempted to elucidate whether low-intensity extracorporeal shock wave therapy (LiESWT) alters bladder angiogenesis, decreases inflammatory response, and ameliorates bladder hyperactivity to influence bladder function in OHD-induced OAB in human clinical trial and rat model. The ovariectomized (OVX) for 12 months Sprague–Dawley rat model mimicking the physiological condition of menopause was utilized to induce OAB and assess the potential therapeutic mechanism of LiESWT (0.12 mJ/mm2, 300 pulses, and 3 pulses/second). The randomized, single-blinded clinical trial was enrolled 58 participants to investigate the therapeutic efficacy of LiESWT (0.25 mJ/mm2, 3000 pulses, 3 pulses/second) on postmenopausal women with OAB. The results revealed that 8 weeks’ LiESWT inhibited interstitial fibrosis, promoted cell proliferation, enhanced angiogenesis protein expression, and elevated the protein phosphorylation of ErK1/2, P38, and Akt, leading to decreased urinary frequency, nocturia, urgency, urgency incontinence, and post-voided residual urine volume, but increased voided urine volume and the maximal flow rate of postmenopausal participants. In conclusion, LiESWT attenuated inflammatory responses, increased angiogenesis, and promoted proliferation and differentiation, thereby improved OAB symptoms, thereafter promoting social activity and the quality of life of postmenopausal participants.

Abstract
Introduction Radial waves are used to treat erectile dysfunction; however, they are different than focal waves, and their mechanism of action or effect on improving this condition is not known. Aim To evaluate the effect of radial waves at the cellular level and their effectiveness at the clinical level for the treatment of erectile dysfunction. Methods Systematic literature review. Electronic database searches and manual searches were performed to identify (i) clinical trials or cohort studies evaluating the effectiveness of radial waves in men with erectile dysfunction and (ii) preclinical trials in animal models or cell cultures in which the production of nitric oxide or endothelial growth factor was evaluated. Study quality was assessed, and data were extracted from each study. A narrative synthesis of the results was performed given the high heterogeneity between the selected studies. Main outcomes measures Nitric oxide production, endothelial growth factor expression, and changes in the Erection Hardness Score (EHS) and the International Index of Erectile Function (IIEF) Questionnaire score. Results Four studies in animal models and 1 randomized clinical trial in men with erectile dysfunction and kidney transplantation were identified that met the selection criteria. Preclinical studies in animals suggest that radial waves increase cellular apoptosis in penile tissue, while vascular endothelial growth factor expression increases in brain tissue. In men with erectile dysfunction, no differences were found between radial wave therapy and placebo therapy in the mean IIEF score (15.6 ± 6.1 vs 16.6 ± 5.4 at 1 month after treatment), EHS (2.5 ± 0.85 vs 2.4 ± 0.7 at 1 month after treatment), or penile Doppler parameters. Conclusions No quality evidence was found to support the use of radial waves in humans for the treatment of erectile dysfunction. In animal models and at the cellular level, the results are contradictory. More research is needed. Sandoval-Salinas C, Saffon JP, Corredor HA, et al.

Abstract
Erectile Dysfunction (ED) is defined as the inability to achieve and maintain an erection sufficient for sexual intercourse. Available treatments for ED provide only symptomatic relief, which is for the most part temporary. Regenerative therapies such as Low Intensity Shockwave, Platelet-Rich Plasma, and Stem Cell therapy can potentially provide a "cure" for ED by reversing the underlying pathology of ED rather than just treating the symptoms. Low Intensity Shockwave therapy is the most evidence based at this point and is thought to act by improving penile blood flow, repairing previous nerve damage, and activating stem cells. Stem Cell therapy takes advantage of the self-replicative potential of stem cells to create new corporal tissue, but also to recruit host cells and angiogenic factors to stimulate endogenous repair. Platelet-Rich Plasma therapy uses concentrated growth factors that already exist within the bloodstream to repair damaged nerves and increase penile blood flow. The use of combination restorative therapy may provide an additive or synergistic benefit greater than any one therapy alone because of its overlapping mechanisms of action on the penis but is a topic that remains to be studied.

Abstract
Simple Summary Overactive bladder (OAB) is a common urologic condition with urinary frequency, urinary urgency, nocturia, and urgency incontinence, which can get in the way of a patient’s social life, exercise, work, and sleep. Exploring a promising option for OAB patients is very important, especially one with less side effects or invasive alternations. This study uses low intensity extracorporeal shock wave therapy (LiESWT) to investigate the therapeutic effect and duration on OAB symptoms. Abstract Background: The present study attempted to investigate the therapeutic effect and duration of low intensity extracorporeal shock wave therapy (LiESWT) on overactive bladder (OAB) symptoms, including social activity and the quality of life (QoL). Methods: In this prospective, randomized, single-blinded clinical trial, 65 participants with OAB symptom were randomly divided into receive LiESWT (0.25 mJ/mm2, 3000 pulses, 3 pulses/second) once a week for 8 weeks, or an identical sham LiESWT treatment without the energy transmission. We analyzed the difference in overactive bladder symptom score (OABSS) and 3-day urinary diary as the primary end. The secondary endpoint consisted of the change in uroflowmetry, post-voided residual (PVR) urine, and validated standardized questionnaires at the baseline (W0), 4-week (W4) and 8-week (W8) of LiESWT, and 1-month (F1), 3-month (F3) and 6-month (F6) follow-up after LiESWT. Results: 8-week LiESWT could significantly decrease urinary frequency, nocturia, urgency, and PVR volume, but meaningfully increase functional bladder capacity, average voided volume and maximal flow rate (Qmax) as compared with the W0 in the LiESWT group. In addition, the scores calculated from questionnaires were meaningfully reduced at W4, W8, F1, F3, and F6 in the LiESWT group. Conclusions: Our results revealed that the therapeutic efficacy of LiESWT could improve voided volume and ameliorate OAB symptoms, such as urgency, frequency, nocturia, and urinary incontinence, and lasted up to 6 month of follow-up. Moreover, LiESWT treatment brought statistically significant and clinically meaningful improvements in social activity and QoL of patients. These findings suggested that LiESWT could serve as an alternative non-invasive therapy for OAB patients.

Abstract
Background For erectile dysfunction (ED) in diabetes mellitus (DM) patients who have poor response to drugs, extracorporeal shock wave therapy (ESWT) and engineered mesenchymal stem cell (MSC) therapy have been studied as alternative treatment options. The objective of this study is to investigate whether ESWT in combination with stromal cell-derived factor-1 expressing engineered mesenchymal stem cell (SDF-1 eMSC) therapy can have synergistic effects on ED in streptozotocin-induced diabetic rats. Methods Fifty 8-week-old male Sprague-Dawley rats were randomly divided into five groups (N=10 per group): (I) Normal group, (II) DM ED, (III) DM ED + ESWT group, (IV) DM ED + SDF-1 eMSC group, and (V) DM ED + ESWT + SDF-1 eMSC group. Each groups were treated with bilateral injections of SDF-1 eMSC or ESWT following the experiment protocol for eight weeks. Results The ratio of ICP/MAP was distinctly higher in the DM ED + ESWT + SDF-1 eMSC group than that in the DM ED group. Concentration of α-smooth muscle actin (α-SMA) was elevated the highest in the DM ED + ESWT + SDF-1 eMSC group. Additionally, ESWT increased the intensity of SDF-1 expression in the corpus cavernosum. ESWT + SDF-1 eMSC treatment also induced neuronal nitric oxide synthase (nNOS) and NO/cGMP expression in the corpus cavernosum. Furthermore, numbers of penile progenitor cells were increased in DM ED rats. Conclusions Combined treatment of ESWT with SDF-1 eMSC treatment is more effective than by a single therapy. It could be used as a potential and effective synergistic treatment for DM ED.

Evaluation of immediate and short-term efficacy of DualStim therapy with and without intracavernosal umbilical cord-derived Wharton's jelly in patients with erectile dysfunction: Study protocol for a randomized controlled trial. Contemp Clin Trials Commun 2021; 23:100790. [PMID: 34278040 PMCID: PMC8267434 DOI: 10.1016/j.conctc.2021.100790] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 04/21/2021] [Accepted: 05/16/2021] [Indexed: 01/22/2023] Open
Abstract
Introduction Erectile dysfunction (ED) affects a significant portion of the United States population and causes negative psychological burdens that affects men and their partner's quality of life and satisfaction. Extracorporeal shock therapy (ESWT) utilizing focused ESWT and radial ESWT in Low-intensity shock wave therapy has been used to treat ED with some success. Wharton's Jelly (WJ) is a biologic substance with large amounts of stem cells, growth factors, cytokines and extracellular components. The use of combined focused and radial ESWT (DualStim therapy) with injected WJ have potential uses in ED that may have advantages over current treatments. Materials A randomized, single-blinded, controlled clinical trial will be conducted to evaluate the efficacy and safety of DualStim therapy and intracavernosal injection of WJ in moderate to severe ED. A total of 60 patients with moderate to severe ED will be enrolled and treated with DualStim therapy with intracavernosal injection of WJ or saline for a period of 7 weeks. The International Index of Erectile Function – Erectile Function score will be used to gauge the treatment related changes in relation to the subject's baseline. The scores will be recorded at baseline and compared to follow-ups 1,3 and 6 months post-treatment. Any adverse events or severe adverse events will be recorded in the corresponding case report forms. Sexual Encounter Profile, as well as the Global Assessment Questionnaire and the Erection Hardness Score will be used to determine the sexual activity improvement from baseline leading to optimal penetration at follow-ups 1,3 and 6 months post-treatment. Discussion This clinical trial is one of the first studies to determine the immediate and short-term efficacy of DualStim therapy, with and without intracavernosal injection of formulated umbilical cord-derived WJ to improve and/or restore erectile function in patients with moderate to severe ED. This study will also provide insight into the safety and efficacy of WJ. We anticipate clinically significant improvement in patients suffering from moderate and severe ED treated with DualStim therapy with WJ compared to their baseline and DualStim with saline.

A Bioinformatic Investigation of the Mechanism Underlying Migraine-Induced Erectile Dysfunction. BIOMED RESEARCH INTERNATIONAL 2021; 2021:6674643. [PMID: 33997039 PMCID: PMC8112924 DOI: 10.1155/2021/6674643] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/29/2020] [Revised: 04/10/2021] [Accepted: 04/21/2021] [Indexed: 11/25/2022]
Abstract
Background Over recent years, an increasing body of literature has focused on the relationship between erectile dysfunction (ED) and migraine. However, the specific mechanism is unclear. Materials and Methods We used a bioinformatic database to predict the targets and pathways associated with migraine and ED. Twenty male SD rats were randomly divided into a blank group (Group A, n = 10) and a migraine model group (Group B, n = 10). The rats in Group A were subcutaneously injected with normal saline (2 ml/kg) into the back of the neck. Rats in Group B were subcutaneously injected with nitroglycerin 10 mg/kg (5 mg/ml) into the back of the neck in order to create an animal model of migraine. Next, we carried out the measurement of erectile function. We used hematoxylin and eosin (HE) to compare the tissue structure of the cavernous body of the penis. Western blotting was used to determine the expression levels of PI3K, p-AKT, and p-mTOR in the protein; Reverse Transcription-Polymerase Chain Reaction (RT-qPCR) was used to determine the expression levels of PI3K, AKT, and mTOR in the messenger ribonucleic acid (mRNA). Results There are 117 intersection targets of migraine and ED, involving 188 cell biological processes (BP), 21 cellular components (CC), 31 molecular functions (MF), and 65 signaling pathways. HE staining results show that there were no significant differences between Group A and Group B with regard to any of the parameters. Compared with Group A, the levels of the PI3K, p-AKT, and p-mTOR proteins and PI3K, AKT, and mTOR mRNAs in Group B decreased (P < 0.01). Conclusions The decline of erectile function in a rat model of migraine was associated with the PI3K/Akt/mTOR signaling pathway.

Abstract
Postprostatectomy erectile dysfunction (pPED) remains a current problem despite improvements in surgical techniques. Vacuum therapy is clinically confirmed as a type of pPED rehabilitation. However, its underlying mechanisms are incompletely understood. Recently, autophagy and apoptosis were extensively studied in erectile dysfunction resulting from diabetes, senescence, and androgen deprivation but not in the context of pPED and vacuum therapy. Therefore, this study was designed to investigate the roles of autophagy and apoptosis in pPED and vacuum therapy. Twenty-four adult male Sprague-Dawley rats were randomly divided into three groups: the control group, bilateral cavernous nerve crush (BCNC) group, and BCNC + vacuum group. After 4 weeks of treatment, intracavernosal pressure was used to evaluate erectile function. Real-time quantitative polymerase chain reaction, western blot, and immunohistochemistry were used to measure the molecular expression. TdT-mediated dUTP nick-end labeling staining was used to assess apoptosis. Transmission electron microscopy was used to observe autophagosomes. After treatment, compared with those of the BCNC group, erectile function and cavernosal hypoxia had statistically significantly improved (P < 0.05). Apoptosis and the relative protein expression of B-cell lymphoma-2-associated X and cleaved Caspase3 were decreased (P < 0.05). Autophagy-related molecules such as phosphorylated unc-51-like autophagy-activating kinase 1 (Ser757) and p62 were decreased. Beclin1, microtubule-associated protein 1 light chain 3 A/B, and autophagosomes were increased (P < 0.05). Besides, the phosphatidylinositol 3-kinase/AKT/mammalian target of rapamycin signaling pathway, as a negative regulator of autophagy to some degree, was inhibited. This study revealed that vacuum therapy ameliorated pPED in BCNC rats by inhibiting apoptosis and activating autophagy.

Abstract
Cell therapies have emerged as a promising therapeutic modality with the potential to treat and even cure a diverse array of diseases. Cell therapies offer unique clinical and therapeutic advantages over conventional small molecules and the growing number of biologics. Particularly, living cells can simultaneously and dynamically perform complex biological functions in ways that conventional drugs cannot; cell therapies have expanded the spectrum of available therapeutic options to include key cellular functions and processes. As such, cell therapies are currently one of the most investigated therapeutic modalities in both preclinical and clinical settings, with many products having been approved and many more under active clinical investigation. Here, we highlight the diversity and key advantages of cell therapies and discuss their current clinical advances. In particular, we review 28 globally approved cell therapy products and their clinical use. We also analyze >1700 current active clinical trials of cell therapies, with an emphasis on discussing their therapeutic applications. Finally, we critically discuss the major biological, manufacturing, and regulatory challenges associated with the clinical translation of cell therapies.

Abstract
Atherothrombosis, a multifactorial and multistep artery disorder, represents one of the main causes of morbidity and mortality worldwide. The development and progression of atherothrombosis is closely associated with age, gender and a complex relationship between unhealthy lifestyle habits and several genetic risk factors. The imbalance between oxidative stress and antioxidant defenses is the main biological event leading to the development of a pro-oxidant phenotype, triggering cellular and molecular mechanisms associated with the atherothrombotic process. The pathogenesis of atherosclerosis and its late thrombotic complications involve multiple cellular events such as inflammation, endothelial dysfunction, proliferation of vascular smooth muscle cells (SMCs), extracellular matrix (ECM) alterations, and platelet activation, contributing to chronic pathological remodeling of the vascular wall, atheromatous plague formation, vascular stenosis, and eventually, thrombus growth and propagation. Emerging studies suggest that clotting activation and endothelial cell (EC) dysfunction play key roles in the pathogenesis of atherothrombosis. Furthermore, a growing body of evidence indicates that defective autophagy is closely linked to the overproduction of reactive oxygen species (ROS) which, in turn, are involved in the development and progression of atherosclerotic disease. This topic represents a large field of study aimed at identifying new potential therapeutic targets. In this review, we focus on the major role played by the autophagic pathway induced by oxidative stress in the modulation of EC dysfunction as a background to understand its potential role in the development of atherothrombosis.

Abstract
This study was to explore the effect and mechanism of Probucol on STZ-induced erectile dysfunction in diabetic rats. Thirty SD male rats aged 12 weeks were given intraperitoneal injection of STZ after fasting for 12 hr. Diabetic rats were haphazardly partitioned under two assemblies and administered 0 or 500 mg/kg probucol by oral gavage to 12 weeks. Control group was intraperitoneally injected with physiological saline, and saline was administered by oral gavage daily. Intracorporeal pressure was used to evaluate erectile function. Levels of proteins were detected using immunohistochemistry and Western blotting. α-SMA and vWF were detected using immunofluorescence staining. After treatment, erectile function in probucol group was significantly improved. Endoplasmic reticulum stress-related proteins were expressed higher in DM group than in sham group, while expression of these proteins decreased significantly in probucol group. However, α-SMA and vWF were expressed at lower levels in DM group than in sham group, and probucol treatment reversed this phenomenon. Finally, Bax and Caspase3 were expressed at higher levels and Bcl-2 was expressed at lower levels in DM group, while the opposite result was obtained in probucol group. In conclusions, probucol improves erectile function by reducing endothelial dysfunction and inhibiting PERK/ATF4/CHOP pathway in STZ-induced diabetic rats.

Abstract
BACKGROUND Mesenchymal stem cells (MSCs) are favourable treatments for ischaemic diseases; however, MSCs from diabetic patients are not useful for this purpose. Recent studies have shown that the expression of miR-34a is significantly increased in patients with hyperglycaemia; the precise role of miR-34a in MSCs in diabetes needs to be clarified. OBJECTIVE The aim of this study is to determine the precise role of miR-34a in MSCs exposed to hyperglycaemia and in recovery heart function after myocardial infarction (MI) in diabetes mellitus (DM) rats. METHODS DM rat models were established by high-fat diet combined with streptozotocin (STZ) injection. MSCs were isolated from the bone marrow of donor rats. Chronic culture of MSCs under high glucose was used to mimic the DM micro-environment. The role of miR-34a in regulating cell viability, senescence and paracrine effects were investigated using a cell counting kit-8 (CCK-8) assay, senescence-associated β-galactosidase (SA-β-gal) staining and vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) ELISA, respectively. The expression of autophagy- and senescence-associated proteins in MSCs and silent information regulator 1 (SIRT1) and forkhead box class O 3a (FoxO3a) were analysed by western blotting. Autophagic bodies were analysed by transmission electron microscopy (TEM). The MI model was established by left anterior descending coronary artery (LAD) ligation, and then, the rats were transplanted with differentially treated MSCs intramuscularly at sites around the border zone of the infarcted heart. Thereafter, cardiac function in rats in each group was detected via cardiac ultrasonography at 1 week and 3 weeks after surgery. The infarct size was determined through a 2,3,5-triphenyltetrazolium chloride (TTC) staining assay, while myocardial fibrosis was assessed by Masson staining. RESULTS The results of the current study showed that miR-34a was significantly increased under chronic hyperglycaemia exposure. Overexpression of miR-34a was significantly associated with impaired cell viability, exacerbated senescence and disrupted cell paracrine capacity. Moreover, we found that the mechanism underlying miR-34a-mediated deterioration of MSCs exposed to high glucose involved the activation of the SIRT1/FoxO3a autophagy pathway. Further analysis showed that miR-34a inhibitor-treated MSC transplantation could improve cardiac function and decrease the scar area in DM rats. CONCLUSIONS Our study demonstrates for the first time that miR-34a mediates the deterioration of MSCs' functions under hyperglycaemia. The underlying mechanism may involve the SIRT1/FoxO3a autophagy signalling pathway. Thus, inhibition of miR-34a might have important therapeutic implications in MSC-based therapies for myocardial infarction in DM patients.

Abstract
There is still a lack of sufficient research on the mechanism behind neurogenic
bladder (NB) treatment. The aim of this study was to explore the effect of
overexpressed stromal cell-derived factor-1 (SDF-1) secreted by engineered
immortalized mesenchymal stem cells (imMSCs) on the NB. In this study, primary
bone marrow mesenchymal stem cells (BM-MSCs) were transfected into immortalized
upregulated SDF-1-engineered BM-MSCs (imMSCs/eSDF-1+) or immortalized normal SDF-1-engineered BM-MSCs
(imMSCs/eSDF-1−). NB rats induced by bilateral pelvic nerve (PN)
transection were treated with imMSCs/eSDF-1+, imMSCs/eSDF-1−, or sham. After a 4-week treatment, the bladder function was assessed by
cystometry and voiding pattern analysis. The PN and bladder tissues were
evaluated via immunostaining and western blotting analysis. We found that imMSCs/eSDF-1+ expressed higher levels of SDF-1 in vitro and in vivo. The treatment of imMSCs/eSDF-1+ improved NB and evidently stimulated the recovery of bladder wall in NB
rats. The recovery of injured nerve was more effective in the NB+imMSCs/eSDF-1+ group than in other groups. High SDF-1 expression improved the levels of
vascular endothelial growth factor and basic fibroblast growth factor. Apoptosis
was decreased after imMSCs injection, and was detected rarely in the NB+imMSCs/eSDF-1+ group. Injection of imMSCs boosted the expression of neuronal nitric
oxide synthase, p-AKT, and p-ERK in the NB+imMSCs/eSDF-1+ group than in other groups. Our findings demonstrated that overexpression
of SDF-1 induced additional MSC homing to the injured tissue, which improved the
NB by accelerating the restoration of injured nerve in a rat model.

Abstract
IMPORTANCE Combining 2 first-line treatments for erectile dysfunction (ED) or initiating other modalities in addition to a first-line therapy may produce beneficial outcomes. OBJECTIVE To assess whether different ED combination therapies were associated with improved outcomes compared with first-line ED monotherapy in various subgroups of patients with ED. DATA SOURCES Studies were identified through a systematic search in MEDLINE, Cochrane Library, and Scopus from inception of these databases to October 10, 2020. STUDY SELECTION Randomized clinical trials or prospective interventional studies of the outcomes of combination therapy vs recommended monotherapy in men with ED were identified. Only comparative human studies, which evaluated the change from baseline of self-reported erectile function using validated questionnaires, that were published in any language were included. DATA EXTRACTION AND SYNTHESIS Data extraction and synthesis were performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. MAIN OUTCOMES AND MEASURES A meta-analysis was conducted that included randomized clinical trials that compared outcomes of combination therapy with phosphodiesterase type 5 (PDE5) inhibitors plus another agent vs PDE5 inhibitor monotherapy. Separate analyses were performed for the mean International Index of Erectile Function (IIEF) score change from baseline and the number of adverse events (AEs) by different treatment modalities and subgroups of patients. RESULTS A total of 44 studies included 3853 men with a mean (SD) age of 55.8 (11.9) years. Combination therapy compared with monotherapy was associated with a mean IIEF score improvement of 1.76 points (95% CI, 1.27-2.24; I2 = 77%; 95% PI, -0.56 to 4.08). Adding daily tadalafil, low-intensity shockwave therapy, vacuum erectile device, folic acid, metformin hydrochloride, or angiotensin-converting enzyme inhibitors was associated with a significant IIEF score improvement, but each measure was based on only 1 study. Specifically, the weighted mean difference (WMD) in IIEF score was 1.70 (95% CI, 0.79-2.61) for the addition of daily tadalafil, 3.50 (95% CI, 0.22-6.78) for the addition of low-intensity shockwave therapy, 8.40 (95% CI, 4.90-11.90) for the addition of a vacuum erectile device, 3.46 (95% CI, 2.16-4.76) for the addition of folic acid, 4.90 (95% CI, 2.82-6.98) for the addition of metformin hydrochloride and 2.07 (95% CI, 1.37-2.77) for the addition of angiotensin-converting enzyme inhibitors. The addition of α-blockers to PDE5 inhibitors was not associated with improvement in IIEF score (WMD, 0.80; 95% CI, -0.06 to 1.65; I2 = 72%). Compared with monotherapy, combination therapy was associated with improved IIEF score in patients with hypogonadism (WMD, 1.61; 95% CI, 0.99-2.23; I2 = 0%), monotherapy-resistant ED (WMD, 4.38; 95% CI, 2.37-6.40; I2 = 52%), or prostatectomy-induced ED (WMD, 5.47; 95% CI, 3.11-7.83; I2 = 53%). The treatment-related AEs did not differ between combination therapy and monotherapy (odds ratio, 1.10; 95% CI, 0.66-1.85; I2 = 78%). Despite multiple subgroup and sensitivity analyses, the levels of heterogeneity remained high. CONCLUSIONS AND RELEVANCE This study found that combination therapy of PDE5 inhibitors and antioxidants was associated with improved ED without increasing the AEs. Treatment with PDE5 inhibitors and daily tadalafil, shockwaves, or a vacuum device was associated with additional improvement, but this result was based on limited data. These findings suggest that combination therapy is safe, associated with improved outcomes, and should be considered as a first-line therapy for refractory, complex, or difficult-to-treat cases of ED.

Exosomes derived from miR-301a-3p-overexpressing adipose-derived mesenchymal stem cells reverse hypoxia-induced erectile dysfunction in rat models. Stem Cell Res Ther 2021; 12:87. [PMID: 33494812 PMCID: PMC7836493 DOI: 10.1186/s13287-021-02161-8] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Accepted: 01/12/2021] [Indexed: 12/19/2022] Open
Abstract
Background Erectile dysfunction (ED) has often been observed in patients with obstructive sleep apnea (OSA). Research on adipose-derived mesenchymal stem cell (ADSC)-derived exosomes has shown that they have significant therapeutic effects in many diseases including ED. Methods In this study, ED was induced in Sprague Dawley (SD) rats using chronic intermittent hypoxia (CIH) exposure. CIH-mediated influences were then measured in the corpus cavernous smooth muscle cells (CCSMCs). Results Our data showed that miR-301a-3p-enriched exosome treatment significantly recovered erectile function in rats and CCSMCs by promoting autophagy and inhibiting apoptosis. The treatment also significantly recovered the level of alpha smooth muscle actin (α-SMA) in rats and CCSMCs. Bioinformatics predicted that phosphatase and tensin homolog (PTEN) and Toll-like receptor 4 (TLR4) might be targets of miR-301a-3p. Conclusions Our results indicate that PTEN-overexpression vectors or TLR4-overexpression vectors reverse the therapeutic effects achieved by miR-301a-3p in CCSMCs indicating that PTEN/hypoxia-inducible factor-1 alpha (HIF-1α) and TLR4 signaling pathways play key roles in the progression of ED. The findings in this study suggest that miR-301a-3p should be considered a new therapeutic target for treating ED associated with OSA.

Abstract
Background The purpose of this study is to explore the effects of high-BDNF microenvironment produced by engineered immortalized mesenchymal stem cells (imMSCs) on the neurogenic bladder (NB) and investigate underlying mechanism. Methods Male Sprague-Dawley rat (12-week-old, weighing about 370-400 g) were purchased from a Korean company (Orient Bio Co. Seongnam, Korea) and divided into the following groups (n=32): sham control group (n=8), NB group (n=8), NB + ImMSCs group (n=8), NB + ImMSCs (BDNF) group (n=8). The major pelvic ganglion (MPG) was observed under anesthesia. Three NB groups of rats were then subjected to bilateral MPG injury. The sham control group of rats was treated with sham surgery. Cystometry were performed before the rats were sacrificed, and then MPG and bladder were collected for histochemical and Western blot analysis. Results MSCs treatment improves lower urinary tract function, and the NB + ImMSCs (BDNF) group is better than the NB + ImMSCs group (P<0.01). MSCs treatment accelerates recovery of injured nerve tissue, and the NB + ImMSCs (BDNF) group is better than the NB + ImMSCs group (P<0.01). In high BDNF environment, apoptosis was reduced more significantly and muscle tissue recovered more rapidly (P<0.01). High-BDNF microenvironment activates more BDNF/TrkB/CREB signaling pathways (P<0.01). Conclusions In a rat NB model caused by nerve injury, imMSCs have certain effects on nerve tissue repair. At the same time, it was proved that increasing the expression of BDNF which had specific effect on nerve injury repair could more effectively repair injured MPG in local microenvironment. The mechanism may be related to the activation of the BDNF/TrkB/CREB signaling pathway and the reduction of apoptosis by highly expressed BDNF.

Abstract
Background Low-intensity shockwave therapy (SWT) is an emerging treatment for erectile dysfunction (ED). Devices used for SWT include focused shockwave therapy (fSWT) or radial wave therapy (rWT), which differ in how the waves are generated, their tissue penetration, and the shape of their pressure waves. Most studies of SWT for ED to date have utilized fSWT. Although widely used, the efficacy of rWT for ED is unknown. Our objective is to compare the efficacy of rWT and fSWT for ED at our institution. Methods A retrospective chart review was performed to identify all men with ED treated by fSWT or rWT. Men with history suggesting non-vasculogenic ED were excluded. All men received 6 consecutive weekly treatments. The fSWT group received 3,000 shocks per treatment at 0.09 mJ/mm2. The rWT group received 10,000 shocks per treatment at 90 mJ and 15 Hz. Pre-treatment and 6-week post-treatment Sexual Health Inventory in Men (SHIM) scores were measured. Treatment response was categorized on a scale of 1–3 (1 if no improvement, 2 if erections sufficient for intercourse with phosphodiesterase 5 inhibitors (PDE5i), or 3 if sufficient erections without PDE5i). Primary endpoint was self-reported improvement score of 2 or greater. Results A total of 48 men were included: 24 treated by fSWT and 24 by rWT. There were no significant differences in age, duration of ED, pre-treatment PDE5i use, or pre-treatment SHIM scores between the groups. Following treatment with rWT, the mean SHIM score improved from 9.3 to 16.1 (P<0.001). The mean SHIM following fSWT improved from 9.3 to 15.5 (P<0.001). The mean improvement in SHIM score did not differ between rWT (6.8) and fSWT (6.2) (P=0.42). 54% of men treated by fSWT experienced a significant clinical improvement (≥ grade 2 response) compared to 75% in the rWT group (P=0.42). There were no reported side effects with either device. Conclusions In our patient population, both fSWT and rWT were moderately effective treatments for arteriogenic ED with no observable difference in efficacy between the two modalities.

Abstract
Recently, extracorporeal shock wave therapy (ESWT) is more commonly used in noninvasive treatment of erectile dysfunction (ED). There is no definitive treatment protocol on the use of ESWT. In this study, we aimed to compare focused and unfocused ESWT in ED. We created two groups, each including 20 patients with similar demographics. Focused ESWT is performed in one group, while unfocused ESWT is performed for the other group. Patients are assessed with IIEF-5 and EHS. Mean score of IIEF-5 was increased by 6.3 ± 3.3 (p < .05) from 9.6 ± 2.9 to 15.0 ± 5.0 in 3-month follow-up in the unfocused group. In the focused group, IIEF-5 score increased by 5.34 in average from 10.01 ± 2.5 to 15.4 ± 3.1. In conclusion, IIEF-5 score was significantly higher in the unfocused ESWT group than the focused ESWT group.

Abstract
Mesenchymal stem cell (MSC) transplantation may serve as an important treatment modality in chronic kidney disease (CKD); however, the underlying mechanisms remain unclear. Advanced oxidation protein products (AOPP) have been demonstrated to induce renal tubular epithelial cell (RTEC) injury via autophagy inhibition. Therefore, the present study was performed to investigate the role of human umbilical cord-derived MSCs (hUC-MSCs) in RTEC autophagy. AOPP-treated HK-2 cells were co-cultured with hUC-MSCs or treated with recombinant humanized hepatocyte growth factor (HGF). Western blotting was used to detect the levels of autophagy-and PI3K/AKT/mTOR signaling pathway-related proteins, and immunofluorescence staining was used to detect the levels of autophagy-related proteins. The HGF protein levels in HK-2 cells and the hUC-MSC co-culture system were measured. The cells were subsequently treated with tivantinib, an HGF competitive inhibitor, and the levels of autophagy-related proteins were detected. Microtubule-associated protein 1 light chain 3B (LC3B) II/LC3B I (LC3II/LC3I) and beclin 1 protein levels were increased, while p62, PI3K, phosphorylated (p)-AKT and the p-mTOR protein levels were decreased in AOPP-treated HK-2 cells co-cultured with hUC-MSC, compared with the group treated with AOPP only. Furthermore, HGF expression was increased in AOPP-treated HK-2 cells co-cultured with hUC-MSC, compared with the group treated with AOPP alone. When HGF activity was inhibited using tivantinib, these effects on LC3II/LC3I, beclin 1, p62, PI3K, p-AKT, and p-mTOR expression were partially reversed. Furthermore, the effects of tivantinib were reversed by Ly294002. In conclusion, the present study revealed that hUC-MSCs partially reversed AOPP-mediated inhibition of autophagy in HK-2 cells via secretion of HGF, indicating that hUC-MSCs may serve as a potential therapy for preventing the progression of CKD.

According to the World Health Organization, more than 150 million people
are diabetic, and this number will increase twofold by the year 2025. Diabetes-related complications
affect all body organ systems, including the penis. Diabetes-induced Erectile Dysfunction (ED) is
caused by neuropathy of the penile nerves and vasculopathy involving the smooth muscle and endothelium
of the corpus cavernosum.
Objective::
This study aims to present an overview of Stem Cell (SC) research in diabetic animal models
of ED, focusing on the function, signaling, and niches that have a prominent role in the regeneration
of cavernosal cells and penile tissues. We highlight common erectile pathologies caused by diabetes
and review relevant preclinical trials. We also discuss paracrine mechanisms of various SC therapies
involved in the repair of endothelial cells and cavernous nerves in these diabetic models.
Method::
A PubMed search was performed, with dates ranging from inception until Mar 31, 2019.
Results::
This review provides a comprehensive evaluation of the various strategies that have been
investigated for improving SC delivery methods, through preclinical literature and published clinical
trials regarding ED in men with diabetes. Various cell-type applications have benefited erectile function
in diabetic models of ED.
Conclusion::
This review examines the progress and remaining challenges in diabetes-related SC research
regarding ED. Moving forward, it is only with a combined effort of basic biology and translational
work that the potential of SC-based therapies in diabetes in ED can be realized.

Clinical Practice Guideline Recommendation on the Use of Low Intensity Extracorporeal Shock Wave Therapy and Low Intensity Pulsed Ultrasound Shock Wave Therapy to Treat Erectile Dysfunction: The Asia-Pacific Society for Sexual Medicine Position Statement. World J Mens Health 2020; 39:1-8. [PMID: 32648375 PMCID: PMC7752510 DOI: 10.5534/wjmh.200077] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Revised: 04/24/2020] [Accepted: 04/27/2020] [Indexed: 12/14/2022] Open
Abstract
Published literature shows low intensity extracorporeal shock wave therapy (LIESWT) and low intensity pulsed ultrasound (LIPUS) therapy to improve erectile function and penile hemodynamic by inducing neovascularisation and promoting tissue regeneration. Key opinion leaders across the Asia Pacific region attended the recent biennial meeting of the Asia Pacific Society for Sexual Medicine in Australia, and presented the current evidence on LIESWT and LIPUS for erectile dysfunction (ED). The clinical findings were internally discussed, and the quality of evidence was graded based on the Oxford Centre for Evidence-Based Medicine recommendations. Existing literature supports the use of LIESWT and LIPUS in men with ED, with many clinical studies reported encouraging results with improved erectile function, good safety profile and short-term durability. However, controversial exists due to sampling heterogeneity, non-standardised treatment protocol and lack of large multiinstitutional studies. There is a need to better define which subgroup of ED population is best-suited, and specific treatment protocol to optimise shock wave energy delivery. More stringent and larger multi-institutional randomised placebo-controlled trials are warranted before clinical adoption of LIESWT and LIPUS as the new standard of care for men with ED.

Abstract
Background A Korean herbal formulation named KH-204 was reported to have an antioxidant effect in our previous study. We hypothesized that Low-intensity extracorporeal shockwave therapy (Li-ESWT) combined with KH-204 would accelerate the treatment of erectile dysfunction (ED) by enhancing antioxidant. We investigated the synergistic effect of Li-ESWT and KH-204 for ED and explored the mechanism. Methods Human umbilical vein endothelial cells (HUVEC) were treated with KH-204 and LI-ESWT in vitro. Fifty 5-week-old male Sprague Dawley rats received an intraperitoneal injection of 5-ethynyl-20-deoxyuridine (EdU) which can label live cells, and were randomly divided into five groups: (I) normal; (II) diabetes mellitus-associated erectile dysfunction (DMED); (III) DMED + KH-204; (IV) DMED + Li-ESWT; and (V) DMED + KH-204/Li-ESWT. Li-ESWT treatment was repeated three times a week every other day for four weeks in group 4 and 5. Meanwhile, rats in group 3 and 5 were orally fed 400 mg/kg of KH-204 daily for 1 month. Following a 1-week washout period, penile tissues were evaluated by immunostaining and Western blotting. Results KH-204 combined with Li-ESWT improved intracavernosal pressure (ICP) in DMED rats. Li-ESWT/KH-204 stimulated HUVEC tube formation and promoted proliferation. Li-ESWT drove progenitor cells to migrate to penile tissue and KH-204 protected penile progenitor cells in the corpus cavernosum. Oxidative stress was relieved by KH-204/Li-ESWT. Treatment with KH-204/Li-ESWT protected penile progenitor cells, which were recruited to the corpus cavernosum by Li-ESWT, from apoptosis via its antioxidant activity. KH-204/Li-ESWT protected penile tissue from oxidative stress by improving the expression of nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1), increasing superoxide dismutase (SOD), decreasing 8-hydroxy-20-deoxyguanosine (8-OHdG), and reducing apoptosis. KH-204/Li-ESWT promoted stromal derived factor-1 (SDF-1) and platelet endothelial cell adhesion molecule-1 (PECAM-1) in DMED rats. Conclusions KH-204 protected penile progenitor cells, which were recruited to the corpus cavernosum by Li-ESWT, from apoptosis via its antioxidant activity. The combination of Li-ESWT and KH-204 as a synergy therapy could be a potential and effective treatment for DMED.

Abstract
Currently, several treatments exist for the improvement of erectile dysfunction (ED). These include medical therapies such as phosphodiesterase type 5 inhibitors (PDE5-Is), invasive methods such as intracavernosal injection therapy of vaso-active substances, vacuum erection devices, and penile prosthesis implants. However, the percentage of patients that are unresponsive to available treatments and who drop out from treatments remains high. Current evidence reveals that the pathogenesis of ED is related to multiple factors including underlying comorbidities, previous surgery, and psychological factors. Diverse approaches using novel molecular pathways or new technologies have been tested as potential therapeutic options for difficultto-treat ED populations. Melanocortin receptor agonist, a centrally acting agent, showed promising results by initiating erection without sexual stimulation in non-responders to PDE5-Is. Recent clinical and pre-clinical studies using human tissues suggested that new peripherally acting agents including the Max-K channel activator, guanylate cyclase activator, and nitric oxide donor could be potential therapies either as a monotherapy or in combination with PDE5-Is in ED patients. According to several clinical trials, regeneration therapy using stem cells showed favorable data in men with diabetic or post-prostatectomy ED. Low-intensity shock wave therapy also demonstrated promising results in patients with vasculogenic ED. There are growing evidences which suggest the efficacy of these emerging therapies, though most of the therapies still need to be validated by well-designed clinical trials. It is expected that, should their long-term safety and efficacy be proven, the emerging treatments can meet the needs of patients hitherto unresponsive to or unsatisfied by current therapies for ED.

Abstract
More and more evidence advises that circular RNAs (circRNAs) function critically in regulating different disease microenvironments. Our previous study found that autotransplantation of adipose-derived mesenchymal stem cells (ADSCs) promotes diabetes wound healing. Exosomes derived in ADSCs play an important regulatory role. This study aimed to characterize if mmu_circ_0000250 played a role in ADSC-exosome-mediated full-thickness skin wound repair in diabetic rats. Endothelial progenitor cells (EPCs) were selected to study the therapeutic mechanism of exosomes in high-glucose (HG)-induced cell damage and dysfunction. Analysis and luciferase reporter assay were utilized to explore the interaction among mmu_circ_0000250, miRNA (miR)-128-3p, and sirtuin (SIRT)1. The diabetic rats were used to confirm the therapeutic effect of mmu_circ_0000250 against exosome-mediated wound healing. Exosomes containing a high concentration of mmu_circ_0000250 had a greater therapeutic effect on restoration of the function of EPCs by promotion autophagy activation under HG conditions. Expression of mmu_circ_0000250 promoted SIRT1 expression by miR-128-3p adsorption, which was confirmed via luciferase reporter assay and bioinformatics analysis. In vivo, exosomes containing a high concentration of mmu_circ_0000250 had a more therapeutic effect on wound healing when compared with wild-type exosomes from ADSCs. Immunohistochemistry and immunofluorescence detection showed that mmu_circ_0000250 increased angiopoiesis with exosome treatment in wound skin and suppressed apoptosis by autophagy activation. In conclusion, we verified that mmu_circ_0000250 enhanced the therapeutic effect of ADSC-exosomes to promote wound healing in diabetes by absorption of miR-128-3p and upregulation of SIRT1. Therefore, these findings advocate targeting the mmu_circ_0000250/miR-128-3p/SIRT1 axis as a candidate therapeutic option for diabetic ulcers.

Abstract
Mesenchymal stromal cells (MSCs) have been a popular platform for cell‐based therapy in regenerative medicine due to their propensity to home to damaged tissue and act as a repository of regenerative molecules that can promote tissue repair and exert immunomodulatory effects. Accordingly, a great deal of research has gone into optimizing MSC homing and increasing their secretion of therapeutic molecules. A variety of methods have been used to these ends, but one emerging technique gaining significant interest is the use of ultrasound. Sound waves exert mechanical pressure on cells, activating mechano‐transduction pathways and altering gene expression. Ultrasound has been applied both to cultured MSCs to modulate self‐renewal and differentiation, and to tissues‐of‐interest to make them a more attractive target for MSC homing. Here, we review the various applications of ultrasound to MSC‐based therapies, including low‐intensity pulsed ultrasound, pulsed focused ultrasound, and extracorporeal shockwave therapy, as well as the use of adjunctive therapies such as microbubbles. At a molecular level, it seems that ultrasound transiently generates a local gradient of cytokines, growth factors, and adhesion molecules that facilitate MSC homing. However, the molecular mechanisms underlying these methods are far from fully elucidated and may differ depending on the ultrasound parameters. We thus put forth minimal criteria for ultrasound parameter reporting, in order to ensure reproducibility of studies in the field. A deeper understanding of these mechanisms will enhance our ability to optimize this promising therapy to assist MSC‐based approaches in regenerative medicine.

Abstract
Erectile dysfunction (ED) is a common condition which reduces quality of life of both patients and their partners, and is a significant health care expense every year. Although phosphodiesterase type-5 inhibitors are the current first-line treatment for men with ED, they are limited by their on-demand dosing, intolerance, and variable efficacy in complex patient populations such as men with multiple medical comorbidities or ED after pelvic surgery. Regenerative medicine has been introduced and investigated in andrology as an encouraging strategy to restore diseased erectile tissue structure and function. Novel regenerative therapies for ED are controversial but are perceived to offer a durable and safe tissue restorative approach to act as a long-term solution to this cumbersome disease process. Here, we review platelet-rich plasma, amniotic fluid membranes, low-intensity extracorporeal shockwave therapy, and stem cell therapy as regenerative strategies to treat ED. Most of these approaches have preclinical and occasionally clinical data to support their ongoing investigation; however, none of these treatments are currently supported for use in ED patients outside of clinical trials.

Abstract
Erectile dysfunction (ED) is one of the significant complications of diabetes mellitus (DM), and CASR plays an important role in cellular antiapoptosis and NO production in the vascular endothelium by activating PKC. The present study was aimed to investigate the efficacy of Leech and Centipede Granules (LCG) through the CaSR/PLC/PKC signaling. Fifty male Sprague-Dawley rats were treated with streptozotocin to induce the DM model. After 10 weeks, an apomorphine test was used to confirm DMED. Rats with DMED were administrated with LCG and U73122 for 4 weeks. Fasting blood glucose, body weight, insulin and glucagon levels were measured. Erectile function in rats was assessed by apomorphine. Serums were measured using enzyme-linked immunosorbent assay and flow cytometry, and penile tissues were harvested for histologic and the expression of related targets analyses. After treatment, fasting blood glucose, body weight, insulin, glucagon levels, and erectile function were significantly ameliorated in the LCG groups. The LOX-1, NOX, and EMPs concentrations were significantly decreased with LCG treatment. LCG also continuously increased NO and decreased ET-1 content in penile tissues. LCG and U73122 administration also improved penile fibrosis by significantly decreasing VCAM-1, ICAM-1, and CD62P. The data also showed that LCG reduced the apoptosis level in the penis. Furthermore, the inhibited activation of the CaSR/PLC/PKC pathway was observed in DMED rats with LCG treatment. Collectively, LCG significantly ameliorated erectile function of DMED rats via increased NO generation, inhibiting endothelial cells apoptosis and penile fibrosis, which might benefit from the suppression of CaSR/PLC/PKC pathway in DMED rats.

Abstract
BACKGROUND Diabetes mellitus-induced erectile dysfunction is a common diabetic complication, and new therapeutics and the pathogenesis of diabetes mellitus-induced erectile dysfunction need to be investigated. OBJECTIVES The aim was to investigate the pathogenesis of diabetes mellitus-induced erectile dysfunction and the pharmacological mechanism of simvastatin treatment in diabetes mellitus-induced erectile dysfunction model rats. MATERIALS AND METHODS A total of 86 male Sprague Dawley rats aged 8 weeks old were used in this study. The rats were divided into three groups: control (normal), diabetes mellitus-induced erectile dysfunction (streptozotocin-injected), and diabetes mellitus-induced erectile dysfunction + simvastatin (sim). Each group was subdivided into two subgroups for in vitro and in vivo analyses. A bioinformatics method was used to detect differences in gene expression in the corpus cavernosum between normal and diabetes mellitus-induced erectile dysfunction rats. Erectile function was measured by a cavernous nerve electrostimulation test. Corpus cavernosum fibrosis was assessed by Masson staining and Western blotting. Immunofluorescence and Western blotting were performed to explore the differential expression of autophagy-related genes and the AMPK-SKP2-CARM1 pathway genes in rat cavernous smooth muscle cells and the corpus cavernosum. The autophagosomes of the corpus cavernosum tissue were observed by transmission electron microscopy. RESULTS Autophagy-related genes and pathways (the AMPK and FoxO pathway) were identified by bioinformatics analysis and confirmed at the protein level. Simvastatin, an AMPK agonist, was used to treat diabetes mellitus-induced erectile dysfunction rats for 8 weeks, demonstrating that erectile function was improved for 80.5% (P < .05) of rats. Corpus cavernosum fibrosis was alleviated (P < .05), and autophagy was further enhanced (P < .05); these results might be partially caused by AMPK-SKP2-CARM1 pathway activation (P < .05). DISCUSSION AND CONCLUSION Simvastatin could enhance protective autophagy by activating the AMPK-SKP2-CARM1 pathway to improve erectile function in diabetes mellitus-induced erectile dysfunction rats.

Abstract
Objectives To evaluate the rapid repair potential of adipose‐derived stem cells (ADSCs) co‐overexpressing VEGF and GDNF on bilateral cavernous nerve injury (BCNI) in rat models. Progressive fibrosis of the penis that occurs shortly after BCNI is a key cause of clinical treatment difficulty of erectile dysfunction (ED). Traditional medications are ineffective for ED caused by BCNI. ADSCs have shown therapeutic effects in animal models, but disappointing in clinical treatment suggests that we should explore optimal treatment of it. Materials and methods We extracted ADSCs from rat epididymis. Lentiviral transfection was verified by western blot and immunofluorescence. Thirty‐six SD rats (10 weeks old) were randomly divided into six groups (n = 6 per group): sham surgery, and remaining five BCNI groups transplanted PBS or ADSCs which were genetically modified by vehicle, VEGF (ADSC‐V), GDNF (ADSC‐G), or VEGF&GDNF (ADSC‐G&V) around major pelvic ganglion (MPG). We investigated the therapeutic effects of BCNI rat model which is characterized by ED, penile tissue fibrosis and hypoxia, and lack of nitrogen nerves or vascular atrophy. Results Erectile function was almost recovered after 2 weeks of transplantation of ADSC‐G&V, promoted cavernous nerve repair, prevented penile fibrosis and preserving the vascular endothelium, which was significant differences amongst ADSC‐V or ADSC‐G. Moreover, GM‐ADSCs were detected in MPG and penis, indicating that their participation in repair of target organs and transverse nerves. Conclusions These promising data indicate that ADSCs co‐overexpressed VEGF and GDNF‐induced synergistic effects, make it a potential tool for recovering of erectile function speedily after BCNI.

Electromagnetic Low-Intensity Extracorporeal Shock Wave Therapy in Patients with Erectile Dysfunction: A Sham-Controlled, Double-Blind, Randomized Prospective Study. World J Mens Health 2019; 38:236-242. [PMID: 31749340 PMCID: PMC7076310 DOI: 10.5534/wjmh.190130] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2019] [Revised: 10/31/2019] [Accepted: 10/31/2019] [Indexed: 11/25/2022] Open
Abstract
Purpose The aim of the present study was to evaluate the efficacy and safety of the electromagnetic-type low-intensity extracorporeal shock wave therapy (Li-ESWT) in patients with erectile dysfunction (ED). Materials and Methods The randomized, sham-controlled, double-blind prospective study was performed at two referral hospitals. Participants were randomized in a 1:1 ratio to receive sham or Li-ESWT for 6 weeks. ED was evaluated at screening and at 4 and 7 weeks after treatment. Participants were asked to complete the international index of erectile function-erectile function (IIEF-EF) domain questionnaire, erection hardness scale (EHS), and sexual encounter profile questionnaire (SEPQ 2 and 3). The development of complications was investigated. Results Eighty-one of 96 patients completed the study. The median change in the IIEF-EF score in the Li-ESWT and sham groups was 5.1 and −2.2 (p<0.001), respectively, at the 7-week follow-up; 47.4% (18/38) patients had EHS <3, of which 77.8% (14/18) showed significant improvement in virtue of Li-ESWT treatment (p=0.001). A significant improvement was observed in the percentage of “Yes” responses to SEPQ 2 and 3 in the Li-ESWT group vs. sham group from baseline to 7-week follow-up (91.3% vs. 69.4%; p=0.008 and 50.0% vs. 14.3%; p=0.002, respectively). No patients reported pain or other adverse events during treatment or follow-up. Conclusions Thus, Li-ESWT could have a role in improving erectile function. Furthermore, it is safe. We believe that Li-ESWT is an attractive new treatment modality for patients with ED.

Abstract
INTRODUCTION Aging men with diabetes mellitus are more easily suffering from erectile dysfunction (ED), which was poor to respond to drugs. Mesenchymal stem cell treatment (MSCT) offers us an alternative approach that might reverse diabetes mellitus erectile dysfunction (DMED). AIM The aim of this study was to review the current studies investigating mesenchymal stem cell approach in diabetic rat models of ED for future research. METHODS A medical literature search was performed in PubMed by using the keywords including erectile dysfunction, mesenchymal stem cells, diabetes mellitus, and rat model. MAIN OUTCOME MEASURE Representative studies on DMED rats treated by MSCT were reviewed. RESULTS Streptozocin-induced type 1 diabetes mellitus rats were used in most studies because of cost and convenience. With the development of stem cell treatment for DMED research, many kinds of stem cells were used in animal experiment, such as bone marrow-derived mesenchymal stem cells, adipose-derived stem cells, human umbilical cord blood mononuclear cells, muscle-derived stem cells, urine-derived stem cells, neural crest stem cells, and endothelial progenitor cells. Although diverse stem cells were applied for DMED treatment, the mechanism behind these approaches was identical, including improving vascular injury, recovering smooth muscle, restoring neuronal cells, inhibiting the generation of inflammatory cytokines, homing mesenchymal stem cells, and decreasing apoptosis in corpus cavernosum. Meanwhile, combination therapies, including MSCT with drug, herb, and low-energy extracorporeal shockwave treatment showed satisfactory results for ED. CONCLUSION It has been proved that MSCT is an effective and safe treatment for the DMED rats. What's more, MSCT might be a potential and promising approach for patients with DMED as a minimally invasive treatment. Combination of MSCT with various methods was proved to be a more efficient treatment and dependable option to make up for deficiencies of MSCT. Kim SW, Zhu GQ, Bae WJ.

Transplantation of Human Urine-Derived Stem Cells Ameliorates Erectile Function and Cavernosal Endothelial Function by Promoting Autophagy of Corpus Cavernosal Endothelial Cells in Diabetic Erectile Dysfunction Rats. Stem Cells Int 2019; 2019:2168709. [PMID: 31582984 PMCID: PMC6754951 DOI: 10.1155/2019/2168709] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2019] [Revised: 07/03/2019] [Accepted: 08/08/2019] [Indexed: 02/07/2023] Open
Abstract
Aims Cavernosal endothelial dysfunction is one of the factors in developing diabetic erectile dysfunction (DED), but the mechanism of cavernosal endothelial dysfunction is unclear. The present study is aimed at determining the contribution of autophagy in cavernosal endothelial dysfunction of DED rats and explaining the therapeutic effect of urine-derived stem cells (USCs). Methods After rat corpus cavernosal vascular endothelial cells (CCECs) were isolated and cultured in vitro, CCECs were treated with advanced glycation end products (AGEs) to mimic the diabetic situation. Autophagy flux, proliferation, and apoptosis of CCECs were determined by mRFP-GFP-LC3 adenovirus infection combined with fluorescence observation and western blot analysis. USCs were isolated from the urine of six healthy male donors, and coculture systems of USCs and CCECs were developed to assess the protective effect of USCs for CCECs in vitro. The contribution of autophagy to the cellular damage in CCECs was evaluated by the autophagic inhibitor, 3-methyladenine (3-MA). Then, DED rats were induced by streptozotocin (50 mg/kg) and screened by apomorphine test (100 μg/kg). In DED rats, USCs or PBS as vehicle was administrated by intracavernous injection (n = 15 per group), and another 15 normal rats served as normal controls. Four weeks after injection, erectile function was evaluated by measuring the intracavernosal pressure (ICP) and mean arterial pressure (MAP). Cavernosal endothelial function and autophagic activity were examined by western blot, immunofluorescence, and transmission electron microscopy. Results In vitro, AGE-treated CCECs displayed fewer LC3 puncta formation and expressed less LC3-II, Beclin1, and PCNA but expressed more p62 and cleaved-caspase3 than controls (p < 0.05). Coculture of USCs with CCECs demonstrated that USCs were able to protect CCECs from AGE-induced autophagic dysfunction and cellular damage, which could be abolished by 3-MA (p < 0.05). DED rats showed lower ratio of ICP/MAP, reduced expression of endothelial markers, and fewer autophagic vacuoles in the cavernosal endothelium when compared with normal rats (p < 0.05). Intracavernous injection of USCs improved erectile function and cavernosal endothelial function of DED rats (p < 0.05). Most importantly, our data showed that the repaired erectile function and cavernosal endothelial function were the result of restored autophagic activity of the cavernosal endothelium in DED rats (p < 0.05). Conclusions Impaired autophagy is involved in the cavernosal endothelial dysfunction and erectile dysfunction of DED rats. Intracavernous injection of USCs upregulates autophagic activity in the cavernosal endothelium, contributing to ameliorating cavernosal endothelial dysfunction and finally improving the erectile dysfunction induced by diabetes.

Abstract
BACKGROUND This study aims to evaluate the effect of extracorporeal shock wave therapy (ESWT) on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and to explore the mechanism. METHODS RWPE-2 cells were randomly divided into three groups: (a) RWPE-2 group (normal control), (b) LPS groups (lipopolysaccharide inducing inflammation) and (c) ESWT groups (LPS induced RWPE-2 treated by ESWT). After ESWT was administered, cells and supernatant were collected for enzyme-linked immunosorbent assay (ELISA) and Western blot analysis. In vivo, Sprague-Dawley rats (n = 30) were randomly divided into three groups: (a) normal control group, (b) prostatitis groups, and (c) ESWT groups. Prostatitis rats were induced by 17 β-estradiol and dihydrotestosterone for 4 weeks. After ESWT, prostates of each group were collected for immunohistochemistry, Western blot analysis, and ELISA. RESULTS ESWT improved prostatitis by attenuating inflammation (P < .01). ESWT downregulated the expression of cyclooxygenase 2 (COX-2) through inhibiting TLR4-NFκB pathway compared with the LPS group in vitro or prostatitis group in vivo (P < .05). TRAF2 mediates ERK1/2-COX2 pathway. ESWT promotes prostate tissue recovery by stimulating vascular endothelial growth factor expression (P < .01). ESWT could suppress apoptosis in the prostate. CONCLUSIONS ESWT improved CP/CPPS and reduced inflammation by degrading COX-2 in microenvironment through TLR4-NFκB-inhibiting pathway. TRAF2 regulator in ERK1/2-COX-2 inhibition significantly reduced inflammation, thus suggesting ESWT may be a potential and promising treatment for CP/CPPS.

In vivo tracking on longer retention of transplanted myocardin gene-modified adipose-derived stem cells to improve erectile dysfunction in diabetic rats. Stem Cell Res Ther 2019; 10:208. [PMID: 31311594 PMCID: PMC6636019 DOI: 10.1186/s13287-019-1325-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2019] [Revised: 06/11/2019] [Accepted: 07/03/2019] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND Stem cell therapy has revealed a promising future for treating erectile dysfunction (ED), but the fate and curative mechanism of intracavernosal transplanted stem cells are under further exploration. This study aimed to demonstrate the effects of myocardin gene modification on improving erectile function and prolonging the retention of implanted adipose-derived stem cells (ASCs) using in vivo small animal imaging. METHODS ASCs were isolated, cultured, and identified by flow cytometry and osteogenic and adipogenic induction. The effects of gene modification on cell proliferation, apoptosis, and contraction were determined by CCK-8, EdU, flow cytometry, and collagen gel lattice contraction assays as well as confocal microscopy. A total of 20 normal and 60 diabetes mellitus ED to (DMED) Sprague-Dawley rats were recruited to the 7 day and 21 day groups. Each group contained subgroups of 10 rats each: the negative control (NC), DMED + ASCs plus Ad-Luc-Myocardin, DMED + ASCs plus Ad-Luc, and DMED + phosphate buffer solution (PBS) groups. Erectile function was evaluated with the intracavernosal pressure/mean arterial pressure (△ICP/MAP) ratio. In vivo small animal imaging and an EdU cell tracking strategy were introduced to detect the transplanted ASCs, and IHC and WB were performed to assess smooth muscle cell protein levels. RESULTS The ASCs expressed high CD29 and CD90 and scant CD45, while the multi-induction potential was verified by oil red O and alizarin red staining. Gene transfection of myocardin had no significant influence on ASC apoptosis but inhibited cell proliferation and promoted cell contraction. Myocardin combined with ASCs enhanced the therapeutic potential of ASCs for improving the △ICP/MAP ratio as well as α-SMA and calponin expression. In vivo imaging confirmed that ASCs resided within the cavernous body in 21 days, while only a few red EdU dots were detected. CONCLUSIONS Myocardin induced ASC differentiation towards smooth muscle-like cells and enhanced the therapeutic potential of ASCs for ameliorating ED in STZ-induced diabetic rats. Notably, in vivo small animal tracking was an effective strategy for monitoring the implanted stem cells, and this strategy might have advantages over traditional EdU assays.

Abstract
Erectile dysfunction (ED) is important to a man’s well-being and health, since it not only affects the individual but also causes strain on a couple’s lifestyle and relationship. There are multiple non-invasive treatments that exist for ED including lifestyle changes, oral medications (phosphodiesterase type 5 inhibitors), vacuum-assisted erectile devices, and intraurethral suppositories. While lifestyle changes and oral medications are typically first-line treatments for ED, more-invasive treatments including intracavernosal injections and surgically implanted prosthetic devices may be required for the management of complex cases. Additionally, novel therapies are currently being developed, and future treatment options may include shock-wave therapy, external prosthetic devices, and injection of stem cells or platelet-rich plasma. The current manuscript seeks to highlight advances in management and may eventually alter the treatment paradigm to allow more-inclusive care pathways.

Abstract
Low-intensity extracorporeal shock wave therapy (Li-ESWT) is a form of energy transfer that is of lower intensity (<0.2mJ/mm2) relative to traditional Extracorporeal Shock Wave Lithotripsy (ESWL) used for management of urinary stones. At this intensity and at appropriate dosing energy transfer is thought to induce beneficial effects in human tissues. The proposed therapeutic mechanisms of action for Li-ESWT include neovascularization, tissue regeneration, and reduction of inflammation. These effects are thought to be mediated by enhanced expression of vascular endothelial growth factor, endothelial nitric oxide synthase, and proliferating cell nuclear antigen. Upregulation of chemoattractant factors and recruitment/activation of stem/progenitor cells may also play a role. Li-ESWT has been studied for management of musculoskeletal disease, ischemic cardiovascular disorders, Peyronie's Disease, and more recently erectile dysfunction (ED). The underlying mechanism of Li-ESWT for treatment of ED is incompletely understood. We summarize the current evidence basis by which Li-ESWT is thought to enhance penile hemodynamics with an intention of outlining the fundamental mechanisms by which this therapy may help manage ED.
