[PMID: 38239203 PMCID: PMC10794918 DOI: 10.3389/fphar.2023.1281002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 11/27/2023] [Indexed: 01/22/2024] Open
Abstract
Background: Chronic non-bacterial prostatitis (CNP), one of the most common chronic diseases in urology, leads to pain in the prostate and dysuria, critically affecting the physical or mental health of patients. However, there are no standard treatment approaches for the treatment of CNP in the clinic. Although the clinical application of Bushen Daozhuo granule (BSDZG) offers hope to CNP patients in China, the mechanisms of BSDZG in treating CNP are still not entirely clear. Hence, we aimed to investigate the novel therapeutic mechanisms of BSDZG on CNP. Methods: In this study, we first assayed the prostate index of rats and then determined the anti-inflammatory and anti-apoptotic effects of BSDZG on CNP in vivo and in vitro by employing ELISA kits and TUNEL staining. Next, we investigated whether the anti-inflammatory and anti-apoptotic mechanisms of BSDZG on prostate protein-induced rats and lipopolysaccharide (LPS) induced RWPE-1 cells were related to the AKT, p38 MAPK, and NF-κB pathways with the help of Western blot. Finally, the influence of BSDZG on the interaction between the p38 MAPK and NF-κB pathway in LPS-induced RWPE-1 cells was explored by adopting dehydrocorydaline (DHC, p38 MAPK activator) with the help of ELISA kits and Western blot. Results: In vivo, BSDZG effectively reduced the prostate index. In vivo and in vitro, BSDZG dramatically declined the level of two pro-inflammatory cytokines, TNF-α and IL-1β, as well as the apoptosis rate. Moreover, in vivo and in vitro, BSDZG memorably upregulated the expression level of p-AKT, and substantially downregulated the expression level of p-p38 MAPK and NF-κB2. The activation of p38 MAPK significantly reversed the moderation effects of BSDZG on the level of TNF-α and IL-1β, as well as the expression level of p-p38 MAPK and NF-κB2 in vitro. Conclusion: To sum up, the in vivo and in vitro therapeutic mechanisms of BSDZG on CNP were reflected as the anti-inflammation and anti-apoptosis that was formed by inhibiting the level of pro-inflammatory cytokines, TNF-α and IL-1β, to regulate the AKT, p38 MAPK, and NF-κB pathways, and the anti-inflammatory effect of BSDZG was realized by suppressing the p38 MAPK pathway to inhibit the downstream NF-κB pathway.

Evidence for a causal effect of major depressive disorder, anxiety on prostatitis risk: A univariate and multivariate Mendelian randomization study. Prostate 2023; 83:1387-1392. [PMID: 37504798 DOI: 10.1002/pros.24601] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 07/05/2023] [Accepted: 07/11/2023] [Indexed: 07/29/2023]
Abstract
BACKGROUND Observational studies have shown an association between major depressive disorder (MDD), anxiety, and prostatitis. However, the causal relationship between MDD, anxiety, and prostatitis remains controversial. Therefore, we aimed to use two-sample Mendelian randomization (MR) to assess the causal effects of MDD and anxiety on prostatitis. METHODS We conducted univariable and multivariable MR analyses using summary statistics from publicly available genome-wide association studies to estimate the causal relationships between MDD, anxiety, and prostatitis risk. In the main MR analysis, the inverse-variance weighted (IVW) method was used, while secondary methods included the weighted median, weighted mode, MR-Egger regression, and MR pleiotropy residual and outlier (MR-PRESSO) tests to detect and correct for the presence of pleiotropy. RESULTS MDD had 97 independent instrumental variables (IVs) and anxiety had 15 IVs. Univariable MR analysis showed that genetically determined MDD had a detrimental causal effect on prostatitis (IVW: odds ratio [OR] = 1.47, 95% confidence interval [CI] = 1.12-1.92, p = 0.005), while no causal relationship was found between anxiety and prostatitis (IVW: OR = 0.25, 95% CI = 0.02-2.82, p = 0.26). More convincingly, after adjusting for confounding factors such as body mass index, alcohol consumption, and smoking, the genetic liability for MDD remained associated with prostatitis risk, with no strong evidence of anxiety affecting prostatitis incidence. CONCLUSION This study supports the notion that MDD has a detrimental effect on prostatitis risk, and strategies focused on addressing MDD may be one of the cornerstones for treating prostatitis. The potential preventive value of treating MDD for prostatitis should be further investigated in future research.

Abstract
OBJECTIVE This study aims to investigate a possible relationship between chronic prostatitis (CP) and Peyronie's disease (PD) and to characterize the psychological profile of patients suffering from PD, with or without concomitant CP. METHODS We included 539 patients with PD, of which 200 were found to have underlying CP. As a comparator population, we selected 2201 patients without PD, referring to our tertiary care clinic. In this population, we detected 384 subjects with CP. All 539 PD patients underwent photographic documentation of the penile deformation, and dynamic penile eco-color Doppler with plaque and volume measurements and answered the following questionnaires: the Generalized Anxiety Disorder-7, the Patient Health Questionnaire-9, the Visual Analog Scale for penile pain measurements, the International Index of Erectile Function (IIEF), and the NIH-Chronic Prostatitis Symptom Index. RESULTS The overall prevalence of chronic prostatitis in PD patients was 37.1% compared to a prevalence of 17.4% in the non-PD control population (OR = 2.79 and p < 0.0001). The severity of CP symptom total scores (NIH-CPSI) correlated significantly with the severity of erectile dysfunction (p < 0.0001). Significant anxiety was present in 89.2% of PD patients and it is more prevalent in PD patients with CP than in PD patients without CP (93.0% vs. 87.0%, respectively; p = 0.0434). Significant depression was detected in 57.1% of PD patients and it is more prevalent in PD patients with CP than in PD patients without CP (64.0% vs. 53.09%, respectively; p = 0.0173). CONCLUSION Chronic prostatitis (CP) and Peyronie's disease (PD) are frequently associated. Our results demonstrate the strong impact of chronic prostatitis on the mental status of PD patients. Anxiety and depression were significantly more pronounced in PD patients with CP than in PD patients without CP.

Abstract
INTRODUCTION/AIM A spectrum of psychological problems is commonly found in CP/CPPS patients, though it is not yet clear whether, a priori, psychological dysfunctions are the cause of these pain syndromes, or whether these pain conditions are themselves causing psychological disturbances. In this article we present the current perspective on the impact of psychological problems in chronic prostatitis syndromes and we discuss the implications thereof from a clinical perspective. MATERIALS AND METHODS A database and a manual search were conducted in the MEDLINE database of the National Library of Medicine, EMBASE, and other libraries using the key words "prostatitis syndromes", "chronic bacterial prostatitis", "chronic pelvic pain", in various combinations with the terms "psychological issues", "depression" "anxiety", "stress", "unhappiness", "cognitive status" and "personality". Two independent reviewers performed data extraction. We included clinical studies with available information on chronic prostatitis and related psychological conditions. We considered full-text written papers. We excluded reviews and case reports. In order to reduce the risk of bias we analyzed only studies including patients with confirmed CBP or CP/CPPS. Bibliographic information in the selected publications was checked for relevant records not included in the initial search. RESULTS Database search allowed us to retrieve 638 studies to which we added to 16 additional studies retrieved by hand-searching. After screening, 34 relevant papers were identified for thorough review. Most studies included patients with chronic pelvic pain and prostatitis-like symptoms, whereas a smaller number of studies included patients with methodologically con- firmed CP/CPPS including studies with a microbiologically confirmed diagnosis of CBP. The psychosocial factors examined in the selected studies include pain, catastrophizing, stress, personality factors and social aspects. Comorbid psychiatric disorders evidenced in the studies included depression, anxiety and trauma-related disorders, somatization disorders, and substance abuse. Some studies investigated the association of pain with each individual psychological disturbance, while others examined the impact of pain in association with the overall quality of life. Sample size, study design and diagnostic measures varied among studies. CONCLUSIONS Despite limitations and variations in sample size, study design and diagnostic measures in all included studies, a relation between chronic prostatitis and psychological problems is a consistent finding. The existing evidence does not permit to definitely conclude whether psychological problems are a risk factor for CP/CPPS or whether they represent an array of symptoms that are associated with the exacerbation of this disease.

Pain Res Manag 2023; 2023:7754876. [PMID: 36960418 PMCID: PMC10030225 DOI: 10.1155/2023/7754876] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Revised: 09/25/2022] [Accepted: 03/04/2023] [Indexed: 03/16/2023]
Abstract
Background Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a complex male dysfunction, mostly seen in young and middle-aged men with a history of more than 3 months. As a traditional therapy of Traditional Chinese Medicine, acupuncture has been proven an effective method to treat CP/CPPS in recent years. Though some meta-analyses on acupuncture for chronic prostatitis were published in 2018 and 2019, most of the included studies were low in quality according to the JADAD score (JADAD < 4). The conclusions of acupuncture for CP/CPPS remain indefinite. Purpose This review aims to evaluate the efficacy of acupuncture for CP/CPPS by including high-quality literature only (JADAD ≥ 4) to provide a reliable basis for clinical applications and research. Method Nine electronic databases were searched from inception to March 1, 2022, and only randomized controlled trials (RCT) with high-quality (JADAD ≥ 4) were included. Data were analyzed using Review Manager 5.3. and was verified through trial sequential analysis (TSA). We carried out a sensitivity analysis for the heterogeneity (I 2 ≥ 50%). Publication bias was explored using a funnel plot. Result Ten RCTs (11 trials) of high-quality methodology involving 798 patients were included. Meta-analysis showed that compared to sham acupuncture (SAT) and western medicine (WM), acupuncture (AT) played superior roles for CP/CPPS patients in pain score, NIH-CPSI score, quality of life score, urinary symptom, and efficacy rate. As for the adverse effects, 4 RCTs described mild hematoma and pain in AT and SAT groups, while specific symptoms including nausea, abdominal pain, dizziness, and low blood pressure were reported in WM groups. Conclusion This meta-analysis indicated that acupuncture has measurable benefits on CP/CPPS, and security has also been ensured. However, this meta-analysis only included 10 RCTs; thus, RCTs with a larger sample size and longer-term observation are required to verify the effectiveness of acupuncture further in the future.

Abstract
Introduction Benign prostatic hyperplasia (BPH) is a non-neoplastic proliferative disease of the prostate. Eriochloa villosa (EV) reportedly possesses various pharmacological activities, including anti-lipase activity and modulation of various antioxidative enzymes. In this study, we investigate the therapeutic potential of EV against BPH in a testosterone-induced BPH rat model. Methods Rats were subjected to a daily subcutaneous injection of testosterone (3 mg kg−1) for 4 weeks to induce BPH. Along with testosterone, rats in the treatment group were administered finasteride (10 mg kg−1) or EV (150 mg kg−1) via oral gavage. Prostatic cancer (LNCaP) cell line was used to examine the effect of EV. Results Finasteride and EV significantly decrease the relative prostate weight, serum levels of dihydrotestosterone and testosterone, and prostate epithelial thickness. Testosterone injection induced prostatic hyperplasia and proliferating cell nuclear antigen expression; however, EV treatment significantly attenuated these effects. Moreover, finasteride- and EV-treated rats exhibit an increase in the number of TUNEL-positive cells and reduced Bcl-2 expression in the prostate tissues compared with the testosterone-treated animals. Furthermore, EV suppresses inflammatory cytokines, including interleukin (IL)-6 and IL-8, in the prostate tissues. Meanwhile, the expression of inflammatory mediator cyclooxygenase-2 is consistently upregulated in testosterone-treated rats, whereas EV treatment significantly reverses this effect. Notably, EV treatment suppresses malondialdehyde (MDA) levels and upregulates testosterone-induced catalase (CAT) expression. In addition, EV suppresses expression of androgen receptor (AR) and prostate-specific antigen (PSA) induced by testosterone in LNCaP cells. Conclusion The present study results suggest that EV regulates prostatic proliferation, apoptosis, response to inflammation, and oxidative stress in the BPH rat model, and may, therefore, serve as a useful therapeutic agent for BPH.

Abstract
Currently, medication for benign prostate hyperplasia (BPH) and prostate cancer (PCa) are mainly based on modulating the hormone and nervous systems. However, side effects often affect patients, and might decrease their commitment to continuing the medication and lower their quality of life. Some studies have indicated that chronic inflammation might be the cause of BPH and PCa. Based on this hypothesis, the effect of phloretin, a potent anti-inflammatory and anti-oxidative flavonoid, has been researched since 2010. Results from animal and in-vitro studies, obtained from databases, also indicate that the use of phloretin in treating BPH and PCa is promising. Due to its effect on inflammatory cytokines, apoptosis or anti-apoptosis, reactive oxygen species, anti-oxidant enzymes and oxidative stress, phloretin is worthy of further study in human clinical trials regarding safety and effective dosages.

Abstract
Objective: Serum amino acid profile is known to vary in many diseases. The changes in the serum amino acid profile provide important information about diagnosis and prognosis of related diseases and the effectiveness of treatment. The aim of this study is to investigate whether serum amino acids are effective in the development of CRS.
Methods: A total of 23 healthy volunteers between the ages of 20 and 40 years were allocated to the control group (Group 1) and 27 patients with chronic rhinosinusitis were allocated to the study group (Group 2). The patients whose history, symptom, and examination findings were consistent with chronic sinusitis and who also who had sinusitis findings on a paranasal sinus tomography and were diagnosed with chronic sinusitis for at least one year were included in Group 2. A total of 32 serum-free amino acid levels were measured in both group using the LC-MS/MS system.
Results: The serum taurine level was found to be statistically significantly lower in Group 2 compared to Group 1 (p:0.002). A significant alteration was not observed in the serum levels of remaining 31 amino acids.
Conclusion: According to the data we obtained from the study, decreased serum taurine level may be a factor in the etiopathogenesis of chronic rhinosinusitis and therefore taurine supplementation may be considered as a new therapeutic target in the treatment of chronic rhinosinusitis.

Abstract
OBJECTIVE We designed this study to investigate the potential use of N-acetylcysteine (NAC) as an adjunct to alpha-blockers in the treatment of category III chronic prostatitis (CP). METHODS Sixty-three men with category III CP with a National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) total score of 15 or more were randomized to either the NAC treatment group or the placebo treatment group. Besides tamsulosin at a dose of 0.4 mg once daily, participants based on their allocation group received NAC or placebo at a dose of 600 mg twice daily for 12 weeks. The efficacy of the medications was assessed by measuring changes in the NIH-CPSI total score and its subscales, including pain, urinary symptoms, and quality of life. RESULTS Based on the general linear model analysis of the data, over the 12-week treatment, NAC+tamsulosin was statistically superior to placebo+tamsulosin in reducing the total NIH-CPSI score, pain subscore, and quality-of-life subscore (P value <.001). Further, after 12 weeks, more patients in the NAC+tamsulosin group than in the placebo+tamsulosin group met the responder criterion, defined as a decrease of at least 6 points in the NIH-CPSI total score (65.6% vs 29.0%). A more favorable outcome was also noted in the NAC+tamsulosin group regarding the number of patients reporting moderate or marked improvement in symptoms (62.5% vs 25.80%). No significant difference was seen between the groups concerning changes in urinary symptoms. CONCLUSIONS Our study provided clinical evidence that men with category III CP might benefit from NAC treatment. Further studies are needed for the validation of these findings.

Dihydroartemisinin Promoted Bone Marrow Mesenchymal Stem Cell Homing and Suppressed Inflammation and Oxidative Stress against Prostate Injury in Chronic Bacterial Prostatitis Mice Model. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:1829736.

Abstract
Although bone marrow mesenchymal stem cells (BMMSCs) are effective in treating chronic bacterial prostatitis (CBP), the homing of BMMSCs seems to require ultrasound induction. Dihydroartemisinin (DHA) is an important derivative of artemisinin (ART) and has been previously reported to alleviate inflammation and autoimmune diseases. But the effect of DHA on chronic prostatitis (CP) is still unclear. This study aims to clarify the efficacy and mechanism of DHA in the treatment of CBP and its effect on the accumulation of BMMSCs. The experimental CBP was produced in C57BL/6 male mice via intraurethrally administered E. coli solution. Results showed that DHA treatment concentration-dependently promoted the accumulation of BMMSCs in prostate tissue of CBP mice. In addition, DHA and BMMSCs cotreatment significantly alleviated inflammation and improved prostate damage by decreasing the expression of proinflammatory factors such as TNF-α, IL-1β, and chemokines CXCL2, CXCL9, CXCL10, and CXCL11 in prostate tissue of CBP mice. Moreover, DHA and BMMSCs cotreatment displayed antioxidation property by increasing the production of glutathione peroxidase (GSH-Px), SOD, and decreasing malondialdehyde (MDA) expression. Mechanically, DHA and BMMSCs cotreatment significantly inhibited the expression of TGFβ-RI, TGFβ-RII, phosphor (p)-Smad2/3, and Smad4 in a dose-dependent manner while stimulated Smad7 expression in the same manner. In conclusion, our findings provided evidence that DHA effectively eliminated inflammatory and oxidative stress against prostate injury, and this effect involved the TGF-β/Smad signaling pathway in CBP.

Abstract
Epidemiological studies demonstrate that men with periodontitis are also susceptible to benign prostatic hyperplasia (BPH) and that periodontal treatment can improve the prostatic symptom. However, molecular links of this relationship are largely unknown. The goal of the current study was to elucidate the effects of experimental periodontitis on the hyperplasia of prostate and whether oxidative stress and inflammation participated in this process. For this purpose, ligature-induced periodontitis, testosterone-induced BPH, and the composite models in rats were established. Four weeks later, all the rats were sacrificed and the following items were measured: alveolar bone loss and histological examination of periodontal tissues were taken to assess the establishment of periodontitis model, prostate index and histological examination of prostate tissues were taken to test the establishment of the BPH model, inflammatory cytokines in plasma were assessed, and Bax/Bcl-2 proteins related to cell apoptosis were analyzed via western blot analysis. To further investigate whether oxidative stress participates in the aggravation of BPH, in vitro models were also conducted to measure the production of intracellular reactive oxygen species (ROS) and hydrogen peroxide (H2O2) concentration. We found that simultaneous periodontitis and BPH synergistically aggravated prostate histological changes, significantly increased Ki67 proliferation, and reduced apoptosis in rat prostate tissues. Also, our results showed that periodontal ligation induced increased Bcl-2 protein expression, whereas Bax expression was decreased in BPH rats than in normal rats. Compared with the control group, periodontitis and BPH both significantly enhanced inflammatory cytokine levels of TNF-α, IL-6, IL-1β, and CRP. Furthermore, Porphyromonas gingivalis lipopolysaccharide induced enhanced generation of intracellular expression of ROS and H2O2 in BPH-1 cells. Our experimental evidence demonstrated that periodontitis might promote BPH development through regulation of oxidative stress and inflammatory process, thus providing new strategies for prevention and treatment of BPH.

Int J Urol 2021; 28:1254-1259. [PMID: 34528294 DOI: 10.1111/iju.14685] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Accepted: 08/17/2021] [Indexed: 12/22/2022]
Abstract
OBJECTIVE To explore the influence of the microbiota of prostate secretion on the clinical status of patients with chronic bacterial prostatitis. METHODS This was an observational, single-center, comparative study. We evaluated the survey cards of 230 outpatients aged 18-45 years with a history of prostatitis from 2012 to 2019. As a result, 170 outpatients were selected for the study. All patients underwent an assessment of symptoms using International Prostate Symptom Score-quality of life, National Institutes of Health-Chronic Prostatitis Symptom Index, International Index of Erectile Function, pain visual analog scale. A bacteriological study (after the Meares-Stamey test) of post-massage urine was carried out on an extended media set. The following parameters were determined in each patient: leukocyturia and bacteriuria, serum testosterone and total prostate-specific antigen levels. Uroflowmetry, transrectal prostate ultrasound with color duplex mapping and ejaculate analysis were also carried out. RESULTS Aerobic-anaerobic bacterial associations were identified in all patients. Three comparison groups were identified depending on the microbiota's spectrum (in post-massage urine): aerobes prevailed in group 1 (n = 67), anaerobes prevailed in group 2 (n = 33), and the levels of aerobic and anaerobic bacteriuria were higher than ≥103 colony-forming units per mL in group 3 (n = 70). It was found that the severity of clinical symptoms (urination disorders, sexual dysfunction etc.) of chronic bacterial prostatitis, laboratory and instrumental changes (testosterone, prostate-specific antigen, prostate volume etc.) in groups 2 and 3 were significantly higher than in group 1. CONCLUSION In patients with chronic bacterial prostatitis, a predominance of anaerobes or a combination of aerobes and anaerobes in a titer of ≥103 colony-forming units per mL in post-massage urine is associated with worse clinical status.

Abstract
OBJECTIVE To investigate the feasibility and effectiveness of Xialiqi capsules in rats with nonbacterial prostatitis. METHODS A total of 90 healthy male SD rats, weighing 200-220 g, were randomly divided into a blank control group (BCG, n=30), a model group (MG, n=30), and an intervention group (IG, n=30). After establishing the model of chronic nonbacterial prostatitis, IG was treated with 50 mg/kg Xialiqi capsules via gavage. The three groups received the same dose of saline via gavage for 7 consecutive days. The differences in leukocytes, phospholipid vesicle density, number of colonies, prostate mass, apparent diffusion coefficient (ADC), degree of inflammatory cell infiltration in the prostate fluid, serum tumor necrosis factor-α (TNF-α), interleukin (IL)-6, IL-8, CD3+, CD8+ levels after intervention were compared in the three groups. RESULTS Compared with the BCG, the number of leukocytes and colonies in the prostate fluid of the MG was elevated, and the density of lipid vesicles was decreased, and the number of leukocytes and colonies in the prostate fluid of the MG significantly decreased and the density of lipid vesicles rebounded after the intervention of Xialiqi capsules (P>0.05). Compared with the BCG, the prostate mass, ADC and the degree of inflammatory cell infiltration were elevated in the MG. There was a significant reversion of the above indices after the intervention of Xialiqi capsules (P<0.05). The serum levels of TNF-α, IL-6 and IL-8 in the MG were significantly higher than those in the IG, and the levels in the IG were higher than that in the BCG (P<0.05). The serum levels of CD3+ and CD8+ in the MG were significantly lower than those in the IG, and the levels in the IG were lower than that in the BCG (P<0.05). CONCLUSION Xialiqi capsules have a good intervention effect on nonbacterial prostatitis, which can significantly alleviate the immune status and reduce the level of cytokines in the serum and tissues of rats.

Abstract
In the past two decades, thousands of documents in the field of prostatitis have been published. This bibliometric analysis aimed to assess the characteristics, hotspots and frontiers trend of global scientific output on prostatitis. With the trend of moderate growth, altogether 2,423 papers were reviewed. The leading role of the United States in global prostatitis research was obvious, while China had developed rapidly in recent years. Queen's University and JOURNAL OF UROLOGY were the most prolific affiliation and journal respectively. Nickel, J. C made the greatest contribution to the field of prostatitis. Five hotspots have been confirmed: (a) male infertility associated with prostatitis and the molecular mechanisms; (b) diagnosis and treatment of prostatitis; (c) inflammation, pain and bladder irritation symptoms; (d) relationship between chronic prostatitis/chronic pelvic pain syndrome, benign prostatic hyperplasia and prostate cancer; (e) epidemiology, complications of prostatitis and improvement of acupuncture. This bibliometric analysis reveals that the international cooperation was becoming more and more close. Hotspot analysis shows that the molecular mechanism of prostatitis will be a hotspot in the future, mainly focussing on inflammatory immunity and oxidative stress.

The Potential Protective Effect of Orange Peel and Selenium against 17β-Estradiol- Induced Chronic Non-Bacterial Prostatitis in Rats. Anticancer Agents Med Chem 2021; 20:1061-1071. [PMID: 32228431 DOI: 10.2174/1871520620666200331102609] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2019] [Revised: 02/20/2020] [Accepted: 02/21/2020] [Indexed: 01/04/2023]
Abstract
BACKGROUND Prostate Cancer (PCa) is defined as a major health problem faced by the male population. AIM We aimed to investigate the protective effects of Orange Peel Extract (OPE) and/or Selenium (Se) on chronic non-bacterial prostatitis in a rat model. METHODS Fifty-six adult male Wistar albino rats were castrated; after 5 days, they were divided randomly into eight groups (n= 7). The control group received saline treatment; while 17β-estradiol (E2) (0.25mg/kg) was injected subcutaneously in rats from Groups V, VI, VII, and VIII to induce chronic non-bacterial prostatitis. They were then treated with OPE (400mg/kg body weight; Groups II, IV, VI, and VIII) and/or sodium selenite (0.5mg/kg body weight; Groups III, IV, VII, and VIII) for 30 days. Interleukin-2 (IL2) and Prostate Cancer Antigen 3 (PCA3) mRNA expressions were determined using qPCR; Prostate-Specific Antigen (PSA) protein expression was determined immunohistochemically. Prostate tissue histology was examined by hematoxylin and eosin staining, and the levels of oxidative stress markers and antioxidant enzymes were measured. RESULTS E2 administration significantly increased IL2 and PCA3 mRNA expressions, and PSA protein expression. It also increased the prostate wet weight and body weight, and lipid peroxidation, nitric oxide, TNF-α, and IL-1β levels, decreased the glutathione and antioxidant enzyme levels and caused distinct histological alterations in the prostate gland. OPE and/or Se markedly improved all the studied parameters due to their antioxidant properties and anti-inflammatory effects. CONCLUSION OPE and Se showed protective effects against 17β-estradiol-induced chronic non-bacterial prostatitis. These results suggest that protection of chronic non-bacterial prostatitis by OPE+Se combination involves anti-oxidation and anti-inflammation. Moreover, their synergistic mechanism was mostly achieved via the regulation of oxidative stress and inflammation processes.

Abstract
Qianliexin capsule (QLX) is a standardized traditional Chinese herbal preparation that has long been used to treat chronic non‐bacterial prostatitis (CNP) and benign prostatic hyperplasia (BPH). This study investigated the anti‐inflammatory activity of QLX in improving lower urinary tract symptoms (LUTS) associated with CNP and BPH. Rat models of CNP and BPH were induced by oestradiol or testosterone (hormonal imbalance) or chemical inflammation (carrageenan). QLX significantly relieved LUTS in CNP and BPH rat model by reducing prostate enlargement, epithelial thickness, pain response time, urine volume and bleeding time, and by improving prostatic blood flow. The expression of the pro‐inflammatory cytokines interleukin (IL)‐1β and tumour necrosis factor (TNF)‐α, the pro‐inflammatory transcription factor nuclear factor kappa‐light‐chain‐enhancer of activated B cells (NF‐κB), and inflammasome components (NLRP3, caspase‐1 and ASC) in CNP and BPH tissues was reduced by QLX addition. QLX treatment was followed by reduced cellular malondialdehyde and increased superoxide dismutase, catalase and glutathione peroxidase activity, consistent with antioxidant activity. Increases in Beclin‐1 expression and the LC3II/I ratio following QLX treatment indicated that autophagy had been induced. QLX relieved LUTS in CNP and BPH rat models by inhibiting inflammation. The underlying mechanisms included inhibition of inflammasome activation, NF‐κB activation, oxidant stress and autophagy.

Abstract
Cardiovascular diseases are the leading cause of death in the world. Atherosclerosis is characterized by oxidized lipid deposition and inflammation in the arterial wall and represents a significant problem in public health and medicine. Some dietary spices have been widely used in many countries; however, the mechanism of their action as it relates to the prevention and treatment of atherosclerosis is still poorly understood. In this review, we focus on the properties of various spice-derived active ingredients used in the prevention and treatment of atherosclerosis, as well as associated atherosclerotic risk factors. We provide a summary of the mechanisms of action, epidemiological analyses, and studies of various components of spice used in the clinic, animal models, and cell lines related to atherosclerosis. Most notably, we focused on mechanisms of action by which these spice-derived compounds elicit their lipid-lowering, anti-inflammatory, antioxidant, and immunomodulatory properties, as well as their involvement in selected biochemical and signal transduction pathways. It is suggested that future research should aim to design well-controlled clinical trials and more thoroughly investigate the role of spices and their active components in the prevention/treatment of atherosclerosis. Based on this literature review, it appears that spices and their active components are well tolerated and have few adverse side effects and, therefore, provide a promising adjunctive treatment strategy for patients with atherosclerosis.

Abstract
To evaluate the effect of resveratrol in rats with chronic prostatitis, 24 rats were randomly divided into the negative control, vehicle-treated and resveratrol groups. The rats in the vehicle-treated group and the resveratrol group were injected subcutaneously with 17-β-oestradiol (0.25 mg/kg) daily for 6 weeks while the rats in the control group were injected with equivalent normal saline. From the 45th day, the rats in the resveratrol group were given resveratrol (10 mg/kg) by gavage per day while the rest rats were given normal saline. After 55 days, all the rats were sacrificed and the prostatic tissue was removed. Morphological changes were examined by light microscope after H&E staining. The expressions of IL-6, IL-8 and TNF-α were determined through ELISA and immunohistochemical staining. As a result, significant inflammatory cell infiltration and fibroblastic hyperplasia were observed in prostatic stroma in the vehicle-treated group compared with the negative control group, as well as the high expression of IL-6, IL-8 and TNF-α. After resveratrol treatment, inflammatory cell infiltration and fibroblastic hyperplasia were shown prominently reduced. Meanwhile, the expression of IL-6, IL-8 and TNF-α was significantly suppressed. For conclusion, resveratrol could attenuate the prostatic inflammation and downregulate the expression of IL-6, IL-8 and TNF-α in rat with oestradiol-induced chronic prostatitis.

Abstract
Tadalafil (TAD) is primarily a treatment drug for erectile dysfunction. Studies have shown that TAD has a therapeutic effect on prostatitis, but the specific mechanism has not been reported. LPS induced RWPE-1 cells to form a model of chronic nonbacterial prostatitis (CNP). Cell activity was measured by MTT assay. Apoptosis was detected by TUNEL assay. Western blot was used to detect the expression of apoptosis-related proteins Bcl-2, Bax, Caspase-3, and cleaved caspase3. ELISA was used to detect the expression of inflammatory cytokines TNF-α, IL-6, and IL-8. GSH, catalase (CAT), and malondialdehyde (MDA) kits were used to detect the expression of oxidative stress-related indicators GSH, CAT, and MDA. Western blot was used to detect the expression of proteins related to Akt/Nrf2 signaling pathway. After different concentrations of TAD were given, the survival rate of LPS-induced RWPE-1 cells decreased, apoptosis increased, and inflammation and oxidative stress decreased. This process is accompanied by the activation of the Akt/Nrf2 signaling pathway. The addition of AKT inhibitor (HY-10249A) reversed the inhibitory effect of TAD on LPS-induced inflammatory response and oxidative stress of RWPE-1 cell. TAD alleviated LPS-induced inflammation and oxidative stress of RWPE-1 cell by regulating the Akt/Nrf2 signaling pathway.

Abstract
Benign prostatic hyperplasia (BPH) is a serious illness affecting middle-aged and elderly male patients. It is a complication of several diseases including metabolic syndrome. BPH has been associated with inflammation and increased oxidative stress in prostatic tissues. Piceatannol (PIC) is an active natural polyhydroxylated stilbene found in many plants. It has profound anti-inflammatory as well as antioxidant activities. However, it suffers relatively poor pharmacokinetic properties. Nanoformulation is an acknowledged approach to improve PIC bioavailability. The goal was to evaluate the ability of PIC in preventing testosterone-induced benign prostatic hyperplasia in rats. PIC was prepared in a self-nanoemulsifying drug delivery system (SNEDDS). Animals were placed into seven groups: 1) control (vehicle), 2) PIC SNEDDS (20 mg/kg), 3) testosterone (3 mg/kg), 4) testosterone + PIC SNEDDS (5 mg/kg), 5) testosterone + PIC (10 mg/kg), 6) testosterone + PIC SNEDDS (20 mg/kg) and 7) testosterone + finasteride (5 mg/kg). Testosterone was injected SC while PIC SNEDDS and finasteride were given orally. All treatments were given once daily, 5 days/week for four consecutive weeks. PIC administration ameliorated increased prostate weights and indices in addition to histopathological alterations. Further it inhibited accumulation of lipid peroxidation, depletion of glutathione (GSH) and exhaustion of catalase (CAT). PIC SNEDDS exhibited anti-proliferative activities as demonstrated by the inhibition of cyclin D1 protein expression and Bcl2 mRNA expression in addition to enhancement of Bax mRNA expression and caspase-3 content. Immunohistochemically, PIC SNEDDS protected against the testosterone-induced increased expression of tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), nuclear factor kappa B (NFκB) and also offered protection against the decline in Nrf2 expression. Further, a significant enhancement of Nfe212 and Homx1 mRNA expression was detected in PIC SNEDDS-treated animals in comparison to the testosterone group. Conclusively, PIC prepared in SNEDDS protects against experimentally induced BPH via modulation of, at least partly, Nrf2/HO-1/NFκB axis.

Abstract
Phytochemical study of the MeOH extract of Cucumis prophetarum fruits (family Cucurbitaceae) by using different chromatographic techniques led to the isolation of three metabolites; spinasterol (1), cucurbitacin B (2), and 2-O-β-D-glucopyranosylcucurbitacin E (3). Their chemical structures were created on the basis of physical, chemical, spectroscopic data 1D (1H and 13C NMR), and 2D NMR (HSQC and HMBC), as well as similarity with literature data. Cucurbitacin B (Cu-B) (2) was found to be the major constituent. Potential protective activities of MeOH extract, CHCl3, and EtOAc fractions and Cu-B were evaluated against carrageenan-induced prostatic inflammation in rats. Acute toxicity was assessed by evaluating LD50. Pretreatment with CHCl3 fraction and Cu-B ameliorated the rise in the prostate index and obviously protected against histopathological changes. Further, MeOH, extract, CHCl3, and EtOAc fractions as well as Cu-B significantly protected against oxidative stress in prostatic tissues. The anti-inflammatory activities of the extract, fractions and Cu-B were confirmed by ameliorating the rise in prostatic content of the inflammatory mediators TNF-α, IL-1β, COX-2, and iNOS induced by carrageenan. In addition, the rise in the chemotactic factors were myeloperoxidase (MPO), F4-80, and monocyte chemoattractant protein-1 (MCP-1) was significantly hampered. In conclusion, three known compounds (1-3) were isolated from Cucumis prophetarum fruits. Cu-B (2) was the major identified compound. Particularly, CHCl3 fraction and isolated Cu-B exhibited potent anti-inflammatory activity against carrageenan-induced prostatitis. The anti-inflammatory activity can be attributed, at least partly, to inhibition of neutrophil and macrophage infiltration into prostatic tissues.

Febuxostat attenuates testosterone-induced benign prostatic hyperplasia in rats via inhibiting JAK/STAT axis. Life Sci 2020; 260:118414. [PMID: 32926929 DOI: 10.1016/j.lfs.2020.118414] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2020] [Revised: 08/30/2020] [Accepted: 09/05/2020] [Indexed: 01/27/2023]
Abstract
AIM To investigate the possible modulatory effect of febuxostat in testosterone-induced benign prostatic hyperplasia (BPH) in rats with emphasis on xanthine oxidase (XO)/Janus Kinases (JAK)/signal transducer and activator of transcription (STAT) axis. MAIN METHODS Male Wistar rats were treated with testosterone with/out febuxostat. Effect of febuxostat on BPH was assessed at the structural level by histopathology and determination of prostate weight/index. Cyclin D1 protein expression was assessed immunohistochemically and the ratio of Bax/Bcl-2 mRNA expression was determined by real time polymerase chain reaction analysis (RT-PCR). Besides, uric acid serum level was determined colorimetrically. Prostatic XO activity, as well as oxidative stress and inflammatory markers were evaluated. Additionally, western blot analysis was performed for determination of JAK-1 and phosphorylated form of STAT-3 expression in tissues. KEY FINDINGS Results revealed that febuxostat inhibited the increase in prostatic weight and index compared to testosterone-treated group. Additionally, febuxostat ameliorated testosterone-induced histopathological changes, prevented the rise in cyclin D1 expression and enhanced Bax/Bcl2 ratio. Febuxostat suppressed testosterone induced- increase in XO activity in prostates and serum level of uric acid. Moreover, it regulated oxidative stress markers including; malondialdehyde (MDA), superoxide dismutase (SOD) activity and glutathione (GSH) content. Also, it inhibited the increase in prostate contents of interleukin-6 (IL-6), interleukin-1β (IL-1 β), tumor necrosis factor (TNF-α) and nuclear factor (NF-κB). Interestingly, febuxostat markedly reduced JAK-1 and subsequent phosphorylation of STAT-3 protein expression. SIGNIFICANCE Febuxostat ameliorates testosterone-induced BPH via suppressing XO/JAK/STAT axis. This may help to re-purpose the use of XO inhibitors.

Abstract
Benign prostatic hyperplasia (BPH) is a nonmalignant enlargement of the prostate common in older men. Diallyl sulfide (DAS), a major component of garlic, has been reported to possess antioxidant, anti-inflammatory, and antiproliferative effects. However, the underlying protective immunomodulatory mechanism of DAS on BPH remains vague. Herein, experimental BPH was induced in rats by daily subcutaneous injection of testosterone propionate (TP) (3 mg/kg, s.c.) for 4 weeks. In parallel, finasteride (Fin) (5 mg/kg, p.o) or DAS (50 mg/kg, p.o.) was administered orally during BPH induction. TP-induced histological alterations and the immune-inflammatory cascade. On the other hand, DAS or Fin administration alleviated all abnormalities induced testosterone. Fin and DAS administration markedly reduced prostate weight by 53% with Fin, and by 60% with DAS. Moreover, serum testosterone and DHT were reduced by 55% and 52%, respectively, with Fin and by 68% and 75%, respectively, with DAS, in concordance with decreased protein expression of androgen receptor (AR), and prostate-specific antigen (PSA). Furthermore, both regime lessen immune-inflammatory milieu, as evidenced by decrease CD4+ T-cells protein expression and associated inflammatory cytokines. Concomitantly, Fin and DAS exhibited marked mitigation in insulin-like growth factor-1 (IGF-1), transforming growth factor-beta1 (TGF-β1), and phosphorylated extracellular signal-regulated kinase (ERK1/2) signaling. Besides alleviating oxidative stress by 53% and 68% in prostatic MDA and by 27% and 7% in prostatic iNOS with Fin and DAS, respectively. In conclusion, this work highlighted a potential therapeutic approach of DAS as a dietary preventive agent against BPH via its anti-inflammatory and immunomodulatory effect along with suppression of the ERK pathway.

The Anti-Inflammatory and Antioxidative Effects of Ningmitai Capsule in the Experimental Autoimmune Prostatitis Rat Model. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:5847806. [PMID: 32595732 PMCID: PMC7275227 DOI: 10.1155/2020/5847806] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/19/2020] [Revised: 04/21/2020] [Accepted: 04/29/2020] [Indexed: 12/16/2022]
Abstract
Objective Ningmitai (NMT) capsule has been widely prescribed for the treatment of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), but the mechanism remains unclear. This study aims to evaluate the therapeutic effects of the NMT capsule in the experimental autoimmune prostatitis (EAP) rat models and explore its possible mechanisms. Methods A total of fifty male Sprague Dawley rats were used in this study. Prostate extract was obtained for the induction of EAP rat models. The EAP rats were randomly divided into the model group, NMT low-dose group (0.45 g/kg/d), NMT medium-dose group (0.90 g/kg/d), and NMT high-dose group (1.80 g/kg/d), with six rats per group. Three NMT treatment groups were administered with the NMT capsule by gavage for 30 days. HE staining was used for histopathological analyses of prostate tissues. Western blotting was used to measure the expression of proinflammatory factors IL-1β and TNF-α. The MDA level was detected to reflect the level of oxidative stress. The bilateral dorsal root ganglia of T3/L1 to S4 were dissected to measure the substance P expression. Results EAP rat models were successfully constructed, in which extensive infiltration of inflammatory cells was found. Treatment of NMT capsule for 30 days and the infiltration of inflammatory cells were significantly mitigated (P < 0.05), especially in the NMT medium-dose group and NMT high-dose group. Moreover, the expression of IL-1β and the level of MDA were significantly decreased (P < 0.05). In addition, NMT treatment could significantly alleviate substance P expression in dorsal root ganglia. Conclusion Our findings demonstrate that the NMT capsule can alleviate inflammatory response and oxidative stress and reduce the production of substance P in EAP rats. This provides a theoretical basis for the clinical application of NMT capsule for CP/CPPS treatment.

Abstract
Toll-like receptor 5 (TLR5) controls endogenous immune responses to pathogens and is a promising target for pharmacological stimulation of anti-tumor immunity. Mobilan is an innovative gene therapy agent consisting of a non-replicating bicistronic adenovirus directing constitutive expression of human Toll-like receptor 5 (TLR5) and the secreted flagellin-based TLR5 agonist, 502s. In mice, Mobilan injection into prostate tumors resulted in autocrine TLR5 signaling, immune system activation, and suppression of tumor growth and metastasis. Here we report a first-in-human placebo-controlled clinical study of Mobilan aimed at evaluating safety, tolerability, pharmacokinetics and pharmacodynamics of a single intra-prostate injection of Mobilan in early stage prostate cancer patients. Mobilan was safe and well-tolerated at all tested doses; thus, the maximum tolerated dose was not identified. Injection of Mobilan induced signs of self-resolving inflammation not present in placebo-injected patients, including transient elevation of PSA and cytokine (G-CSF, IL-6) levels, and increased lymphoid infiltration in prostate tissue. The highest dose of Mobilan (1011 viral particles) produced the best combination of safety and pharmacodynamic effects. Therefore, Mobilan is well-tolerated and induces the expected pharmacodynamic response in humans. These results support further clinical development of Mobilan as a novel immunotherapy for prostate cancer.

Abstract
Background The relationship between chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and erectile dysfunction (ED) has been shown in many studies. However, the specific mechanism remains unclear. This study was to investigate the corpus cavernosum smooth muscle cell function and phenotype transformation in Experimental autoimmune prostatitis (EAP) rats. Methods EAP was induced in rats by using prostate protein supplemented with immuneadjuvant extraction, and the max-ICP and MAP were measured. IHC and Masson staining were done to assess inflammatory infiltration and collagen deposition in the corpus cavernosum, respectively. Subsequently, normal rat and EAP rat CCSMCs were purified by tissue block implantation and differential adherence method. The oxidative stress, smooth muscle phenotype transformation, cell cycle and intracellular calcium ion transport were also evaluated. Results The ratio of max ICP/MAP in EAP rats significantly reduced, and the TNF-α content and collagen deposition in the corpus cavernosum markedly increased as compared to healthy rats. High-purity rat CCSMCs were obtained. Oxidative stress was evident and the cGMP content decreased in the EAP rat CCSMCs. The expression of Cav1.2, IP3R1 and RyR2 increased, but the SERCA2 expression decreased in EAP rat CCSMCs, which was accompanied by increased intracellular calcium. Increased expression of OPN, collagen and KCa3.1, decreased Calponin expression and increased proportion of cells in the S phase were also observed in the EAP rat CCSMCs. Conclusion CP causes oxidative stress and imbalance of intracellular calcium in CCSMCs and promotes CCSMCs transformation from contractile to synthetic state, which may be involved in the pathogenesis of ED.

Abstract
Chronic cigarette smoke (CS) exposure induces prostate deficits. We previously found that swertiamarin had prostatic protective potential. This study was to investigate the possible protective effect of swertiamarin against CS-induced prostate dysfunction on human prostate epithelial cells, stromal cells and rats. Rat prostate collagen deposition and fibrosis were assessed by sirius red staining and measuring hydroxyproline content, as well as by qPCR and western blot analysis for fibrotic extracellular matrix components. Prostatic levels of oxidative stress and inflammatory-related factors were also analyzed. In order to explore its underling mechanisms, the activities of Hedgehog signaling pathway and epithelial-mesenchymal transition of human prostate cells and rat prostate tissue were estimated. It was found that swertiamarin ameliorated CS-induced prostatic collagen deposition, relieved oxidative stress and local inflammation, inhibited the activation of Hedgehog signaling pathway and attenuated epithelial-mesenchymal transition. It indicated that swertiamarin could ameliorate CS-induced prostatic fibrosis by inhibiting epithelial-mesenchymal transition and Hedgehog pathway.

Abstract
Investigations on prostate inflammation-related disorders, including acute and chronic prostatitis, chronic pelvic pain syndrome, benign prostate hyperplasia (BPH), and prostate cancer (PCa), are still ongoing to find new, accurate, and noninvasive biomarkers for a differential diagnosis of those pathological conditions sharing some common macroscopic features. Moreover, an ideal biomarker should be useful for risk assessment of prostate inflammation progression to more severe disorders, like BPH or PCa, as well as for monitoring of treatment response and prognosis establishment in carcinoma cases. Recent literature evidence highlighted that changes in the expression of transglutaminases, enzymes that catalyze transamidation reactions leading to posttranslational modifications of soluble proteins, occur in prostate inflammation-related disorders. This review focuses on the role specifically played by transglutaminases 4 (TG4) and 2 (TG2) and suggests that both isoenzymes hold a potential to be included in the list of candidates as novel diagnostic biomarkers for the above-cited prostate pathological conditions.
