Abstract
Icariin exerts antioxidative and anti-inflammatory effects and is used in the treatment of bronchial asthma. However, the specific modes of action are uncertain. In this study, we investigated whether icariin could modulate the silencing information regulator 2-related enzyme 1 (SIRT1)/adenosine monophosphate-activated protein kinase (AMPK)/peroxisome proliferator-activated receptor gamma co-activator 1α (PGC-1α) axis by regulating miR-138-5p during H2O2-induced proliferation of mouse airway smooth muscle cells (ASMCs). Primary BALB/c mouse ASMCs were cultured using the tissue block adherence method and were induced with hydrogen peroxide (H2O2; 200 μmol/L) to establish a bronchial asthma ASMC proliferation model. With the aid of Western Blot and quantitative real-time polymerase chain reaction (qRT-PCR) in H2O2-induced ASMCs, the expression of miR-138-5p, SIRT1, AMPK, PGC-1α, α-smooth muscle actin (α-SMA), transforming growth factor-β1 (TGF-β1), collagen I, and collagen III protein and mRNA were investigated. The proliferation rate and activities of superoxide dismutase1 (SOD1), reduced glutathione (GSH), malonaldehyde (MDA), and reactive oxygen species (ROS) in ASMCs were determined. The results suggest Compared with the H2O2-induced group, icariin inhibited the miR-138-5p expression; enhanced SIRT1, p-AMPK, and PGC-1α expression; attenuated MDA activity and ROS level; lowered TGF-β1, collagen I, and collagen III expression levels; and decreased the proliferation of ASMCs induced by H2O2. The dual-luciferase reporter gene assay results showed that SIRT1 is a regulatory target of miR-138-5p.The results suggest that Icariin could improve the H2O2-induced proliferation of ASMCs. The mechanism may be related to the increase of activation of SIRT1/AMPK/PGC-1α axis by suppressing the expression of miR-138-5p. Thus, SIRT1 is the regulatory target of miR-138-5p.

Abstract
Among scaffolds used in tissue engineering, natural biomaterials such as plant-based materials show a crucial role in cellular function due to their biocompatibility and chemical indicators. Because of environmentally friendly behavior and safety, green methods are so important in designing scaffolds. A key bioactive flavonoid of the Epimedium plant, Icariin (ICRN), has a broad range of applications in improving scaffolds as a constant and non-immunogenic material, and in stimulating the cell growth, differentiation of chondrocytes as well as differentiation of embryonic stem cells towards cardiomyocytes. Moreover, fusion of ICRN into the hydrogel scaffolds or chemical crosslinking can enhance the secretion of the collagen matrix and proteoglycan in bone and cartilage tissue engineering. To scrutinize, in various types of cancer cells, ICRN plays a decisive role through increasing cytochrome c secretion, Bax/Bcl2 ratio, poly (ADP-ribose) polymerase as well as caspase stimulations. Surprisingly, ICRN can induce apoptosis, reduce viability and inhibit proliferation of cancer cells, and repress tumorigenesis as well as metastasis. Moreover, cancer cells no longer grow by halting the cell cycle at two checkpoints, G0/G1 and G2/M, through the inhibition of NF-κB by ICRN. Besides, improving nephrotoxicity occurring due to cisplatin and inhibiting multidrug resistance are the other applications of this biomaterial.

Abstract
Background and Objective Although epimedium herb (EH) has been widely used in ancient Chinese medicine to enhance sexual activity, its pharmacological mechanism is not clear. Modern studies have shown that epimedium herb is rich in icariin (ICA, a flavonoid compound), and 91.2% of icariin is converted to icariside II (ICA II) by hydrolytic enzymes in intestinal bacteria after oral administration. YS-10 is a synthetic derivative of icariside II. The aim of this review was to summarize the contemporary evidence regarding the pharmacokinetics, therapeutic properties, and molecular biological mechanisms of ICA and some ICA derivatives for erectile dysfunction therapy. Methods A detailed search was conducted in the PubMed database using keywords and phrases, such as “icariin” AND “erectile dysfunction”, “icariside II” AND “erectile dysfunction”. The publication time is limited to last 20 years. Articles had to be published in peer reviewed journals. Key Content and Findings ICA and its some derivatives showed the specific inhibition on phosphodiesterase type 5 (PDE5) and the promotion of testosterone synthesis. In addition, by regulating various reliable evidence of signaling pathways such as PI3K/AKT, TGFβ1/Smad2, p38/MAPK, Wnt and secretion of various cytokines, ICA and ICA derivatives can activate endogenous stem cells (ESCs) leading to endothelial cell and smooth muscle cell proliferation, nerve regeneration and fibrosis inhibition, repair pathological changes in penile tissue and improve erectile function. Conclusions ICA and some of its derivatives could be a potential treatment for restoring spontaneous erections. In addition ICA and his derivatives may also be valuable as a regenerative medicine approach for other diseases, but more clinical and basic researches with high quality and large samples are recommended.

Abstract
Introduction Spilanthes acmella has been used as an aphrodisiac in India and other countries. However, studies concerning humans have been limited. This randomized controlled trial was carried out to evaluate the effect of SA3X capsules containing 500 mg of S. acmella on sexual function domain scores in sexually active men with symptoms of erectile dysfunction (ED) using the Men’s Sexual Health Questionnaire (MSHQ). Materials and methods This triple-blind, placebo-controlled, parallel-group was conducted at two centres in Hyderabad and Secunderabad from May to December 2021. Patients were randomized 1:1 to SA3X therapy or placebo for one month along with an observational cohort. The change of MSHQ score and its subdomains from baseline to month 1 (primary endpoint) and one-month post-treatment (secondary outcome) was assessed using a mixed model repeated measures analysis. Additional secondary outcomes measured were the change in the International Index of Erectile Function (IIEF) and duration of penile erection. Safety was evaluated. Results The intention-to-treat population included 448 patients (152 - SA3X therapy; 146 - placebo; 150 - observational cohort). A significant increase was observed with SA3X therapy versus placebo on the total MSHQ score (17.24 vs 4.72; SE: 2.11, 1.98; P<0.001) along with the sub-domains at the end of one month of therapy. At one-month post-treatment, the increase in MSHQ score with SA3X therapy was significant (18.48 vs 3.78; SE 2.81, 1.39; P<0.001). The IIEF scores and duration of penile erection also increased significantly in the SA3X therapy group. Dysgeusia (3.94%) was the most common drug-related adverse effect. No serious adverse effects were noted. Conclusion SA3X was concluded to be safe and effective as a potential treatment for ED.

Abstract
OBJECTIVES To investigate the effect of icariin on endothelial microparticles, endothelial progenitor cells, platelets, and erectile function in spontaneously hypertensive rats. MATERIALS AND METHODS Twelve 8-week-old healthy male Wistar-Kyoto rats and 12 spontaneously hypertensive rats were randomly divided into four following groups: Wistar-Kyoto control group (normal saline 1 ml/d given by gavage), Wistar-Kyoto + icariin group (icariin 10 mg/kg × d dissolved in 1 ml normal saline and given by gavage), spontaneously hypertensive rats control group (normal saline 1 ml/d given by gavage), and spontaneously hypertensive rats + icariin group (icariin 10 mg/kg × d dissolved in 1 ml normal saline and given by gavage). Four weeks later, the maximum intracavernous pressure/mean arterial pressure, platelet count, mean platelet volume, platelet distribution width, endothelial microparticles, endothelial progenitor cells, and vitronectin receptor were measured in each group. RESULTS Under 3 or 5 V electrical stimulation, the maximum intracavernous pressure/mean arterial pressure in the spontaneously hypertensive rats + icariin group (0.23 ± 0.03, 0.38 ± 0.02) was significantly higher compared to the spontaneously hypertensive rats control group (0.12 ± 0.02, 0.20 ± 0.02) (p<0.05). Platelet count, mean platelet volume, and platelet distribution width in the spontaneously hypertensive rats + icariin group (1103.67 ± 107.70 × 109 /L, 9.08 ± 0.50 fl, 11.87 ± 0.45%) were significantly lower than those in the spontaneously hypertensive rats control group (1298.00 ± 89.54 × 109 /L, 9.72 ± 0.44 fl, 13.03 ± 0.59%) (all p < 0.05). Endothelial microparticles, endothelial progenitor cells, and vitronectin receptor in the spontaneously hypertensive rats + icariin group (1.01 ± 0.28%, 1.53 ± 0.65%, 2.13 ± 0.53%) were significantly lower than those in the spontaneously hypertensive rats control group (1.58 ± 0.19%, 2.71 ± 0.64%, 3.76 ± 0.52%) (all p < 0.05). Moreover, maximum intracavernous pressure/mean arterial pressure was strongly negatively correlated with platelet distribution width and vitronectin receptor (r > 0.7), and maximum intracavernous pressure/mean arterial pressure was moderately negatively correlated with mean platelet volume, endothelial microparticles, and endothelial progenitor cells (0.5 < r<0.7). CONCLUSION Icariin may improve erectile function in spontaneously hypertensive rats by reducing the content of endothelial microparticles in blood and inhibiting the activation of the platelets. Endothelial microparticles, endothelial progenitor cells, and platelet activation-related (mean platelet volume, platelet distribution width, and vitronectin receptor) can be used as indicators for icariin to improve erectile function in spontaneously hypertensive rats.

Abstract
We explored the efficacy and mechanisms of salidroside treatment for erectile dysfunction induced by bilateral cavernous nerve injury (BCNI). Forty male rats were divided into four groups as follows: sham (cavernous nerves exposed only) (S); BCNI (M); BCNI + rapamycin (M + rapamycin); and BCNI + salidroside (M + salidroside). Erectile function in the rats was measured by intracavernosal pressure. Penile tissue was harvested for transmission electron microscopy, immunohistochemistry, immunofluorescence, Masson's trichrome staining, haematoxylin-eosin staining, TdT-mediated dUTP Nick End Labeling and western blotting. The M group exhibited a decrease in erectile responses and increased apoptosis and fibrosis compared to these in the S group. Meanwhile, nerve content and the penile atrophy index were also decreased in the M group. Treatment with salidroside and rapamycin for 3 weeks partially restored erectile function and significantly attenuated corporal apoptosis, fibrosis, nerve content and penile atrophy in the M group. Moreover, the autophagy level was further enhanced in the M + salidroside group, which was the same as that in the positive observation group (M + rapamycin). Salidroside treatment not only improved erectile function in rats with BCNI, but also inhibited apoptosis and fibrosis and ameliorated the loss of nerve content and endothelial and corpus cavernosum smooth muscle cells by promoting protective autophagy.

Abstract
Neurogenic erectile dysfunction (NED) is an inevitable postoperative disease of cavernous nerve injury which will lead to various pathophysiological changes in the corpus cavernosum and dorsal penile nerve caused by radical prostatectomy (RP). Although serval years of clinical application of HJIG I granules (HJIG), an innovative formulation, has demonstrated its reliable clinical efficacy against NED, the mechanism of HJIG remains unclear. This study aimed to assess the neuroprotective effect of HJIG, to repair damaged nerves in a rat model of bilateral cavernous nerve injury (BCNI) in vivo and their effects on neurites of major pelvic ganglia (MPG) regeneration and Schwann cells (SCs) proliferation in vitro. Rats were divided into five groups randomly: normal control (NC), BCNI-induced ED model (M), M + low-dose HJIG (HL), M + medium-dose HJIG (HM), and M + high-dose HJIG (HH). All groups were treated with normal saline or the relevant drug for 28 consecutive days after a standard NED animal model. Our data revealed that administration of HJIG improved NED that was detected by intracavernous pressure (ICP) in a dose-dependent manner. The haematoxylin-eosin (HE) and Immunofluorescence (IF) staining demonstrated that HJIG ameliorate the shape of penis and induced the protein synthesis of GAP43, NF200, S100, and nNOS. NF200 and S100 level were also detected by western blotting. Moreover, HJIG (0.78 mg/mL) markedly increased SCs viability and promoted neurites regeneration of MPG. These findings provide new insights into the NED therapy by HJIG.

Abstract
BACKGROUND Adipose derived stem cells (ADSCs) have the property to differentiate into neuron-like cells, which may provide a novel insight for the restoration of erectile dysfunction (ED) mainly induced by cavernous nerve injury. Icariside II (ICA II) has been reported to play a key role in the regulation of erectile function via stimulating the differentiation of ADSCs to Schwann Cells (SCs). However, the function and molecular mechanisms of ICA II in ED remains to be further clarified. METHODS The expression of S100, P75, GDNF and miR-33 was detected by qRT-PCR. And the relative proteins expression was determined by western blot. Cell viability was measured by Cell Counting Kit-8 (CCK-8) assay. Bioinformatics, luciferase reporter and RNA immunoprecipitation (RIP) assays were performed to verify the interaction between miR-33 and GDNF. Intracavernosal pressure (ICP), the ratio of ICP and mean arterial pressure (MAP), as well as nNOS expression were examined to evaluate the erectile function of SD rats with bilateral cavernous nerve injury (BCNI). RESULTS ICA II and miR-33 respectively promoted and inhibited the differentiation of ADSCs to SCs. MiR-33 could negatively regulate P75 and GDNF expression. ICA II exerted promotion effects on differentiation of ADSCs to SCs via regulating miR-33. GDNF was identified to be a target of miR-33. MiR-33 overexpression abrogated the stimulatory effect of ICA II on ADSCs' differentiation, which was blocked by GDNF overexpression. treated with ICA II recovered the erectile function of BCNI model rats through regulation of miR-33. CONCLUSION ICA II contributed to the differentiation of ADSCs to SCs viamiR-33/GDNF axis, contributing to the recovery of erectile function in BCNI rats.

Abstract
BACKGROUND Intracavernous injection (ICI) of adipose-derived stem cells (ADSCs) has been demonstrated promising for neurogenic erectile dysfunction (ED). However, due to the sponge-like structure of corpus cavernosum (CC) with abundant vessels, ICI was indeed like intravenous injection. Thus, the cell escaping may be a concern of safety and limited therapy, but the issue has not been clearly demonstrated yet. METHODS Suspensions of free ADSCs (FAs) and ADSCs-based spheroids (ASs) with suitable size were intracavernously injected at doses of 0.5, 1, 2, or 4 million cells. The cell loss and safety after ICI, erectile function and histopathologic change, etc. were analyzed with multimodality of methods. FINDINGS Most FAs escaped from sponge-like CC after ICI due to their small size, weakening stem-cell therapeutic efficacy. Worse still, the escaped cells were shown to cause widespread pulmonary embolism (PE), and even death in some animals. Further, it was founded that the therapeutic effect of FAs may be ascribed to the larger cell clusters which spontaneously aggregated before ICI and were trapped within CC after ICI. In comparison, cell loss and PE were significantly avoided by transplanting ASs. Importantly, better therapeutic outcomes were detected after ICI of ASs when compared to FAs with the same cell number. INTERPRETATION Transplantation of size-specific ASs instead of single-cell suspension of FAs for neurogenic ED may be a wiser choice to achieve steady therapeutic outcome and to reduce risks for the future clinical application.

Abstract
Salidroside, a major active ingredient isolated from Rhodiola rosea, has a long application in Chinese medical history. It has widely demonstrated effects on fatigue, psychological stress, and depression and exhibits potential antihypoxia activity. Emerging evidence shows that hypoxia is an important independent risk factor for erectile dysfunction (ED). The aim of this study was to clarify the effect of salidroside on hypoxia-induced phenotypic transformation of corpus cavernosum smooth muscle cells (CCSMCs). Our results showed that salidroside decreased the hypoxia-induced expression of collagen and content of vimentin, a corpus cavernosum smooth muscle synthetic protein, in vitro. Simultaneously, salidroside increased expression of the CCSMC contractile proteins, α-smooth muscle actin (α-SMA) and desmin. In vivo, similarly, the expressions of collagen and hypoxia-inducible factor-1α were increased in bilateral cavernous neurectomy (BCN) rats while they were decreased in the salidroside group. Among the phenotypic proteins, α-SMA and desmin increased and vimentin decreased after treating BCN rats with salidroside compared with the BCN alone group. Overall, our results demonstrate that salidroside has the ability to oppose hypoxia and can inhibit the CCSMC phenotypic transformation induced by hypoxia. Salidroside may provide a new treatment method for ED.
