[PMID: 38631296 DOI: 10.1159/000538750] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Accepted: 04/04/2024] [Indexed: 04/19/2024]
Abstract
INTRODUCTION Erectile dysfunction (ED) is a widespread disorder, and the worldwide incidence is rapidly increasing. Acupuncture, an intervention out of the spectrum of traditional Chinese medicine (TCM), has a long tradition as treatment for ED. Nonetheless, a best-practice treatment protocol is currently missing. A recent systematic review and meta-analysis confirmed a huge diversity of acupuncture treatments for ED and concluded that there is an urgent need to standardise acupuncture treatment for ED. Consequently, the authors conducted a Delphi process with the aim to achieve an expert consensus as a basis for the development of a best-practice protocol. METHODS The Delphi process consisted of four rounds of questionnaires with closed and open-ended questions. Eleven acupuncture experts participated. The therapeutic aim was defined as "to achieve an erection sufficient for sexual satisfaction." RESULTS Consensus was achieved on 24 acupoints corresponding to 12 TCM syndromes. The syndromes were KI Yang xu, KI Yin xu, KI Qi xu, Ki and HT not harmonised, LR Qi Stagnation, LR Qi stagnation and Heat, Liver Blood xu, Liver Blood xu and Liver Qi stagnation, Damp-heat sinking to the lower Jiao5, HT and GB Qi xu, SP xu and HT Blood xu, Yin xu. The suggested optimal dose was between 11 and 15 treatments given once or twice a week. CONCLUSION An expert consensus-based, semi-standardised best-practice treatment protocol for the treatment of ED was developed. Moreover, the Delphi process also revealed inconsistencies as to which signs and symptoms constitute a TCM syndrome. Further Delphi studies including a broader range of experts from various acupuncture traditions are needed to establish further agreement. Nonetheless, the best-practice protocol introduced in this study provides a first point of departure for the implementation of a more standardised treatment approach. Moreover, since a recent meta-analysis concluded that more high-quality clinical studies on the topic are needed, this study provides a first standardised acupuncture treatment protocol for ED.

Abstract
Acupuncture is gaining popularity and wider acceptance as a treatment modality within the field of sports medicine. Our objective was to provide a comprehensive review of the existing literature pertaining to acupuncture in sports medicine to shed light on approaches utilized in acupuncture while revealing its personalized nature and its impact on athletes' preparation, performance, and recovery. We evaluated acupuncture research in the context of medicine and sports-related injury treatment, assessing its impact on athletic performance across demographics of athletes. Athletes participating in most sports have shown positive outcomes from acupuncture interventions. Acupuncture improves peak oxygen levels, maximum heart rate, delayed-onset muscle soreness, pain, swelling, explosive force production, and joint mobility. Furthermore, the efficacy of acupuncture appears to be similar regardless of age and sex. Lastly, the acceptance of acupuncture is influenced by cultural factors, with Western and traditional East Asian cultures exhibiting distinct perspectives on its rationale and mechanisms of action. Traditional East Asian acupuncturists typically employ qi and meridian theories in their acupuncture practices, with the recent incorporation of Western concepts. Acupuncture shows promise as an effective treatment for musculoskeletal pain and neuropathies in athletes across different age groups and for addressing injuries in various sports. Our comprehensive review will enhance our understanding of acupuncture's potential as a complementary or distinct therapeutic approach compared to conventional therapies. Additionally, our review explores its specific applications within different sports and delves into the cultural dimensions involved in integrating this practice into modern sports medicine.

[PMID: 36848898 DOI: 10.1111/andr.13420] [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: 09/22/2022] [Revised: 02/11/2023] [Accepted: 02/23/2023] [Indexed: 03/01/2023]
Abstract
BACKGROUND Several patients with erectile dysfunction do not accept or benefit from conventional therapy with phosphodiesterase type 5 inhibitors; thus, alternative and complementary therapies are in need. Traditional Chinese medicine has been treating erectile dysfunction in China, but its clinical value is inconclusive. OBJECTIVE To systematically evaluate the efficacy and safety of traditional Chinese medicine in treating erectile dysfunction. METHODS Randomized controlled trials were retrieved from a comprehensive search in the literature published in the past decade from the Web of Science, PubMed, Embase, Cochrane Library, SinoMed, China National Knowledge Internet, WanFang, and VIP. We performed a meta-analysis of the International Index of Erectile Function 5 questionnaire scores, clinical recovery rates, and testosterone levels using Review Manager 5.4 software. The trial sequential analysis was conducted to check the results. RESULTS A total of 45 trials with 5016 patients were included. Meta-analysis results showed that traditional Chinese medicine effectively improved the International Index of Erectile Function 5 questionnaire scores (weighted mean difference = 3.78, 95% confidence interval: 3.12, 4.44; p < 0.001), clinical recovery rates (risk ratio = 1.57, 95% confidence interval: 1.38, 1.79; p < 0.001), testosterone levels (weighted mean difference = 2.42, 95% confidence interval: 1.59, 3.25; p < 0.001) compared with the controls. The single and add-on applications of traditional Chinese medicine could improve the International Index of Erectile Function 5 questionnaire score (p < 0.001). The trial sequential analysis confirmed the robustness of the analysis of the International Index of Erectile Function 5 questionnaire scores. A significant difference in the incidence of adverse effects between the treatment and control groups was not observed (risk ratio = 0.82, 95% confidence interval: 0.65, 1.05; p = 0.12). CONCLUSION Traditional Chinese medicine can gain better responses in improving the International Index of Erectile Function 5 questionnaire scores, clinical recovery rates, and testosterone levels as an alternative and complementary treatment, with no increase in side effects. However, more standardized, long-term, traditional Chinese medicine and integrative therapy clinical trials are needed to support the clinical application of traditional Chinese medicine.

Abstract
OBJECTIVES Sexual dysfunction can adversely affect the quality of life and interpersonal relationships. nowadays, a lot of attention is paid to traditional Chinese medicine with better curative effects and less adverse events. Recent studies have implied the promising effect of acupuncture on sexual function. This systematic review evaluate the effectiveness and safety of acupuncture in treating female and male sexual dysfunction. CONTENT PubMed, Cochrane Central of Controlled Trials (CENTRAL), EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), Scopus, and Google Scholar were searched up to 2021. No limitation to language and date. The methodological quality of the studies was assessed using the Mixed Methods Appraisal Tool (MMAT). SUMMARY Among 160 initially assessed papers, 13 articles were included. The findings showed that acupuncture improve sexual dysfunction in domains of desire, libido, erectile dysfunction and impotency. Most studies did not report any serious side effects from acupuncture, and only three studies reported minor adverse events. OUTLOOK The available evidence indicate that acupuncture has positive on improvement of sexual dysfunction with no serious side effects. Although acupuncture has gained increasing popularity for the management of sexual dysfunction, high methodological quality evidence regarding its efficacy is lacking.

Abstract
Background Psychogenic erectile dysfunction (PED) can seriously affect emotional and marital wellbeing. Electroacupuncture (EA) seems an effective method for treating PED. However, the central mechanisms underlying PED and the beneficial effects of EA treatment are unclear. The purpose of this study was to explore the central mechanisms of PED and to examine the impact of EA on erectile function. Methods We recruited 14 PED patients and 14 matched normal controls (NCs). PED patients underwent twice rs-fMRI scans, respectively, pre- and post-treatment. The NCs only completed one rs-fMRI scan. We used the fractional amplitude of low frequency fluctuation (fALFF) to compare spontaneous neural activity between the PED patients and NCs, and to examine the differences between the pre- and post-EA treatment scans in the PED patients. Results Scores on the IIEF5, QEQ, and SEAR improved after EA treatment. Compared with the NCs, PED patients showed increased fALFF in the right posterior cingulate cortex (PCC), right dorsolateral prefrontal cortex (DLPFC), right supplementary motor area (SMA), and left middle occipital gyrus. Most of these regions are closely implicated in sexual inhibition. The results of the correlation analysis results indicated that the fALFF of the right PCC was negatively correlated with IIEF5 scores. After treatment, fALFF values were substantially lower in the left triangular part of the inferior frontal gyrus, right DLPFC, right SMA, bilateral PCC and the orbital part of the middle frontal gyrus, and higher in the left middle temporal gyrus and left caudate nucleus. These regions mainly belong to the default mode network (DMN), executive control network and primary sensory motor network. The results of the correlation analysis indicated a positive association between the changes in IIEF5 score and changes in the fALFF value in the right PCC after EA treatment. Conclusion In conclusion, our study highlights that PED patients have abnormal patterns of activity in the right PCC, right DLPFC, and right SMA mainly involved in the DMN, executive central network, and sensory motor network which could lead to a higher levels of sexual inhibition. EA might regulate the process of sexual inhibition to improve erection function in PED patients probably by modulating spontaneous brain activity in the DMN, executive central network, and sensory motor network.

Abstract
IMPORTANCE Acupuncture is a popular treatment that has been advocated for dozens of adult health conditions and has a vast evidence base. OBJECTIVE To map the systematic reviews, conclusions, and certainty or quality of evidence for outcomes of acupuncture as a treatment for adult health conditions. EVIDENCE REVIEW Computerized search of PubMed and 4 other databases from 2013 to 2021. Systematic reviews of acupuncture (whole body, auricular, or electroacupuncture) for adult health conditions that formally rated the certainty, quality, or strength of evidence for conclusions. Studies of acupressure, fire acupuncture, laser acupuncture, or traditional Chinese medicine without mention of acupuncture were excluded. Health condition, number of included studies, type of acupuncture, type of comparison group, conclusions, and certainty or quality of evidence. Reviews with at least 1 conclusion rated as high-certainty evidence, reviews with at least 1 conclusion rated as moderate-certainty evidence, and reviews with all conclusions rated as low- or very low-certainty evidence; full list of all conclusions and certainty of evidence. FINDINGS A total of 434 systematic reviews of acupuncture for adult health conditions were found; of these, 127 reviews used a formal method to rate certainty or quality of evidence of their conclusions, and 82 reviews were mapped, covering 56 health conditions. Across these, there were 4 conclusions that were rated as high-certainty evidence, and 31 conclusions that were rated as moderate-certainty evidence. All remaining conclusions (>60) were rated as low- or very low-certainty evidence. Approximately 10% of conclusions rated as high or moderate-certainty were that acupuncture was no better than the comparator treatment, and approximately 75% of high- or moderate-certainty evidence conclusions were about acupuncture compared with a sham or no treatment. CONCLUSIONS AND RELEVANCE Despite a vast number of randomized trials, systematic reviews of acupuncture for adult health conditions have rated only a minority of conclusions as high- or moderate-certainty evidence, and most of these were about comparisons with sham treatment or had conclusions of no benefit of acupuncture. Conclusions with moderate or high-certainty evidence that acupuncture is superior to other active therapies were rare.

Abstract
Erectile dysfunction (ED) is one of the most common sexual dysfunctions in men. The prevalence of ED has been increasing in recent years, which has critically affected male reproductive health and quality of life. According to various guidelines, phosphodiesterase-5 inhibitors are the most commonly recommended drugs for treating ED. However, many patients turn to alternative therapies because of adverse reactions, such as headache, and the poor efficacy of these drugs. Acupuncture is a long-established treatment in traditional Chinese medicine (TCM) and has been approved by the World Health Organization for improving penile erection as well as other discomforts in patients. However, previous systematic reviews have not discussed the characteristics and the related mechanisms of acupuncture treatment. Therefore, this study focuses on summarizing the characteristics and advantages of TCM in acupuncture treatment for ED based on relevant literature and on predicting and analyzing the related mechanisms.

The Effect of Phosphodiesterase-type 5 Inhibitors on Erectile Function: An Overview of Systematic Reviews. Front Pharmacol 2021; 12:735708.

Abstract
Background: Multiple systematic reviews explore the effect of phosphodiesterase type 5 (PDE5) inhibitors on erectile dysfunction (ED), with each study addressing specific outcomes. However, physicians and policymakers require a holistic approach of this topic. Objective: To summarize the current evidence regarding the efficacy and safety of PDE5 inhibitors for the management of ED through an overview of systematic reviews. Methods: Studies were identified by searching PubMed, Web of Science, Cochrane Library and Scopus databases, as well as sources of grey literature until June 12, 2021 (PROSPERO: CRD42020216754). We considered systematic reviews, meta-analyses or network meta-analyses of randomized trials that provided outcomes about the efficacy and safety of any approved PDE5 inhibitor (avanafil, sildenafil, tadalafil and vardenafil). We constructed forest plots for meta-analytic effects regarding the change in erectile function, adverse events and dropouts after administration of PDE5 inhibitors in the general population and in specific patient groups. Results: We included 23 studies with 154,796 participants and a total of 258 meta-analytic effects. Sildenafil 25 mg [Weighted Mean Difference (WMD): 13.08, 95% Confidence Interval (CI): 10.1-16.06] seemed to be statistically superior to all interventions in improving erectile function compared to placebo, but studies with low-dose sildenafil are lacking. Moreover, comparing among different PDE5 inhibitors, sildenafil 50 mg or sildenafil 100 mg were considered the most effective compounds in the general population. The latter derived, however, predominantly from indirect comparisons among different PDE5 inhibitors. Still, sildenafil 100 mg was associated with more treatment-related adverse events and dropouts. Interestingly, low-dose daily tadalafil may be more effective than high-dose on-demand tadalafil (WMD: 1.24, 95% CI: 0.03-2.44). Furthermore, testosterone and PDE5 inhibitors in patients with ED and hypogonadism seem to further improve symptoms, while the addition of a-blockers in patients with urinary symptoms treated with PDE5 inhibitors does not provide additional benefits (WMD: −0.8, 95% CI: −1.65-0.06). Conclusion: Although the efficacy and safety of PDE5 inhibitors, compared to placebo, is well-documented, the existing evidence comparing different PDE5 inhibitors is low. Therefore, high-quality, head-to-head, trials comparing different PDE5 inhibitors are necessary to determine their ideal dosage and formulation based on their safety and efficacy profile. Systematic Review Registration: PROSPERO, identifier [CRD42020216754].

Abstract
OBJECTIVE To construct a corpus cavemosum smooth muscle cell (CCSMCs) line with TEAD1 knockout from diabetic rats with erectile dysfunction (ED) using CRISPR/Cas9 technology and explore the role of TEAD1 in phenotypic modulation of CCSMCs in diabetic rats with ED. OBJECTIVE Models of diabetic ED were established in male Sprague-Dawley rats by intraperitoneal injection of streptozotocin. CCSMCs from the rat models were primarily cultured and identified with immunofluorescence assay. Three sgRNAs (sgRNA-1, sgRNA-2 and sgRNA-3) were transfected via lentiviral vectors into 293T cells to prepare the sgRNA-Cas9 lentivirus. CCSMCs from diabetic rats with ED were infected by the lentivirus, and the cellular expression of TEAD1 protein was detected using Western blotting. In CCSMCs infected with the sgRNA-Cas9 lentivirus (CCSMCs-sgRNA-2), or the empty lentiviral vector (CCSMCs-sgRNA-NC) and the blank control cells (CCSMCs-CK), the expressions of cellular phenotypic markers SMMHC, calponin and PCNA at the mRNA and protein levels were detected using real-time fluorescence quantitative RT-PCR (qRT-PCR) and Western blotting, respectively. OBJECTIVE The primarily cultured CCSMCs from diabetic rats with ED showed a high α-SMA-positive rate of over 95%. The recombinant lentivirus of TEAD1-sgRNA was successfully packaged, and stable TEAD1-deficient CCSMC lines derived from diabetic rat with ED were obtained. Western blotting confirmed that the protein expression of TEAD1 in TEAD1-sgRNA-2 group was the lowest (P < 0.05), and this cell line was used in subsequent experiment. The results of qRT-PCR and Western blotting showed significantly up-regulated expressions of SMMHC and calponin (all P < 0.05) and down-regulated expression of PCNA (all P < 0.05) at both the mRNA and protein levels in TEAD1-deficient CCSMCs from diabetic rats with ED. OBJECTIVE We successfully constructed a stable CCSMCs line with CRISPR/Cas9-mediated TEAD1 knockout from diabetic rats with ED. TEAD1 gene knockout can induce phenotype transformation of the CCSMCs from diabetic rats with ED from the synthetic to the contractile type.
