Clinical Study on Treatment of Chronic Prostatitis with Lingze Tablets Combined with TCM Herbal Acupoint Plasters

Objective:To study the therapeutic effect of Lingze tablets combined with traditional Chinese medicine herbal acupoint plasters on chronic prostatitis.Methods:A total of 64 patients with chronic prostatitis who were admitted to the Andrology Clinic of Shuyang County Hospital of Traditional Chinese Medicine from March 2021 to March 2023 were randomly divided into a treatment group and a control group,with 32 cases in each group.The control group took Lingze tablets orally,4 tablets/time,3 times/d;the treatment group took the same medication along with traditional Chinese medicine acupoint herbal plasters.The two groups of patients were treated continuously for 6 weeks,and the differences in the relevant indexes of the curative effect were observed.Results:The NIH-Chronic Prostatitis Symptom Index(NIH-CPSI)scores of the two groups significantly reduced after treatment(P<0.05),and the scores of the patients in the treatment group were lower than those in the control group(P<0.05).The treatment received in the treatment group achieved and efficacy of 96.88%,which was significantly higher than that of the group,which was 81.25%(P<0.05).The maximum flow rate(MFR),average flow rate AFR,and urine output of the patients of both groups improved significantly after treatment(P<0.05).However,the experimental group showed better improvements in these indicators(P<0.05).Conclusion:Lingze tablets combined with traditional Chinese medicine acupoint herbal plasters can significantly improve the symptoms and urodynamic function of patients with chronic prostatitis.

Treatment of chronic prostatitis in Chinese men

The aim of this study is to assess the status of treatment of chronic prostatitis(CP)in Chinese men.A population-based cross-sectional survey was performed,in which 15000 men aged between 15 and 60 years were randomly selected to receive a questionnaire designed to assess National Institutes of Health Chronic Prostatitis Symptoms Index(NIH-CPSI)status,therapeutic efficacy and 28 other items.A total of 12743 men(84.95%)completed the questionnaire,of whom 1071(8.4%)were identified as having prostatitis-like symptoms and 517(4.5%)were diagnosed with CP according to NIH-CPSI criteria and prostatitis-like symptomatology.Of the CP patients,372(65%)underwent long-term routine treatment 12 times per year.Additionally,217(72.8%)patients received antibiotic therapy and 215(79.3%)men showed therapeutic effects.The treatment cost USD 1151(8059 yuan)per person per year on average.Most CP patients received routine treatment,in most cases with antibiotics.Treatment was costly and most CP patients were not satisfied with its effectiveness.Antibacterial treatment might have been effective primarily in patients with bacterial disease.

Characterisation of the bacterial community in expressed prostatic secretions from patients with chronic prostatitis/chronic pelvic pain syndrome and infertile men： a preliminary investigation

The expressed prostatic secretions （EPSs） of men with chronic prostatitis/chronic pelvic pain syndrome （CP/CPPS）, infertile men and normal men were subjected to microbiological study. EPSs were collected from the subjects, which included 26 normal men, 11 infertile patients and 51 CP/CPPS patients. DNA was extracted from each specimen, and the V3 regions of the 16S rRNA genes were amplified using universal bacterial primers. The results showed that the EPS 16S rRNA gene-positive rate in the CP/CPPS and infertile patients was much higher than in the normal men, but without any difference among the three patient groups. The denaturing gradient gel electrophoresis （DGGE） method was used to characterize the EPS bacterial community structure of the prostate fluid from patients with CP/CPPS or infertility issues. Principal component analysis （PCA） and partial least squares （PLS） analyses of PCR-DGGE profiles revealed that the EPS bacterial community structure differed among the three groups. Three bands were identified as the key factors responsible for the discrepancy between CP/CPPS patients and infertile patients （P〈O.05）. Two bands were identified as priority factors in the discrepancy of category IliA and category IIIB prostatitis patients （P〈O.05）. According to this research, the ecological balance of the prostate and low urethra tract, when considered as a microenvironment, might play an important role in the maintenance of a healthy male reproductive tract.

Redundant prepuce increases the odds of chronic prostatitis/chronic pelvic pain syndrome （CP/CPPS）

Some published evidence has revealed that the dendritic cells can interact with pathogens that exist in the inner foreskin. This information provides a new vision that pathogens could play a role through the redundant prepuce; numerous studies have failed to find pathogens in prostates of patients who had chronic prostatitis/chronic pelvic pain syndrome （CP/CPPS）. However, no studies have reported an association between foreskin length and CP/CPPS. Hence, we conducted a retrospective case-control study of clinical data from 322 CP/CPPS patients （case group） and 341 nonCP/CPPS patients （control group）. Demographic characteristics, lifestyle factors, and foreskin lengths were collected and analyzed. Multivariate logistic regression was adopted to calculate the odds of foreskin length for CP/CPPS. According to the multivariate logistic regression results, when the foreskin length covered up more than half of the glans penis, the odds for CP/CPPS were higher with an increased foreskin （odds ratio （OR）： 1.66, 95% confidence interval （CI）： 1.04-2.66）. In comparison, when the glans penis was completely covered by the foreskin, the OR value increased to 1.86 （95% CI, 1.2-2.88）. The study results showed an association between foreskin length and the odds of CP/CPPS. When the foreskin length covered up more than half of the glans penis, there were greater odds for CP/CPPS. This possible mechanism might result from interaction between pathogens and DCs in the inner foreskin, consequently activating T-cells to mediate allergic inflammation in the prostate and producing the autoimmunizations causing CP/CPPS.

Factors influencing the diagnosis and treatment of chronic prostatitis among urologists in China

Aim. To identify the factors influencing diagnosis and treatment of chronic prostatitis （CP） among Chinese urologists. Methods： A sample of 656 urologists from 29 provinces of China were asked to complete a questionnaire that explored attitudes towards CP as well as diagnosis and treatment patterns in the management of CP. Both univariate and multivariate logistic regression analysis schemes were used to determine the factors that influence the diagnosis and treatment of CP. Results： A total of 656 questionnaires were given out. All were returned and 410 of those were included in the final univariate and multivariate analysis. Multivariate logistic regression analysis indicated that belief of bacterial infection in the etiology of CP （odds ratio [OR], 2.544; 95% confidence interval [CI], 1.650-3.923; P 〈 0.001） was the most significant factor influencing the routine performance of bacterial culture test. Using the same model, the type of hospital （OR, 2.799; 95% CI, 1.719-4.559; P 〈 0.001） and the routine use of the 4- or the 2-glass test （OR, 3.194; 95% CI, 2.069-4.931; P 〈 0.001） were determined to be significant factors influencing the use of the National Institutes of Health （NIH） new classification system. According to the same model, belief of bacterial infection in the etiology of CP （OR, 3.415; 95% CI, 2.024-5.762; P 〈 0.001） and the routine use of bacterial culture test （OR, 2.261; 95% CI, 1.364-3.749; P 〈 0.01） were important factors influencing the routine prescription of antibiotics. Conclusion： Our findings suggest that attitudes towards CP, and the characteristics of individual urologists＇ practices may influence the diagnosis and treatment of CP among Chinese urologists.

Endotoxins in the prostatic secretions of chronic prostatitis patients

Aim: To evaluate the clinical significance of the quantitative determinations of endotoxins in the expressed prostatic secretions (EPS) of chronic prostatitis (CP) patients. Methods: The EPS of 45 patients with CP and 15 normal volunteers were obtained for microscopic examination, bacterial culture and endotoxin determination. The level of endotoxins was determined by the Limulus-amebocyte-lysate test with chromogenic substrate. Results: Patients with CP had higher mean levels of endotoxins in EPS than normal volunteers [52.06 ± 32.83 EU.L^(-1) vs. 4.77 ± 4.14 EU'L^(-1) (P < 0.05)]. The levels of endotoxins in CP type Ⅱ, type Ⅲa and type Ⅲb were 68.62 ± 34.78 EU.L^(-1), 45.30± 23.33 EU.L^(-1) and 15.83 ± 5.31 EU·L^(-1), respectively [type Ⅱ vs. type Ⅲa (P > 0.05), type Ⅲb vs. normal controls (P > 0.05), type Ⅱ/type Ⅲa vs. normal controls P < 0.05)]. Conclusion: CP patients have elevated levels of endotoxins in the EPS, which suggests that inflammation is a feature of this disease. EPS endotoxin determination is not only helpful in diagnostic confirmation, but also in evaluating the response to treatment in CP patients.

A review of the literature on randomized controlled trials of acupuncture and moxibustion in the treatment of chronic prostatitis/chronic pelvic-pain syndrome within 2016-2021

Chronic prostatitis(CP)/chronic pelvic-pain syndrome(CPPS)is a common urinary-system disease with a high incidence in young and middle-aged men,seriously affecting patients'ability to work and their quality of life(Qo L).Western medicine(WM)has some limitations in treating CP/CPPS.Acupuncture is an ancient Chinese medical method that is commonly used to treat this condition and has a relatively good effect on it.Many randomized controlled trials(RCTs)on this subject have been published.For this study,we searched the China National Knowledge Infrastructure(CNKI),Chinese Science and Technology Periodical(VIP),Wanfang,Sino Med,and Pub Med databases for RCTs on acupuncture treatment of CP/CPPS in the last 5 years(2016/01/01-2021/12/01).In addition,we conducted analysis and research,aiming to summarize acupuncture treatment in CP/CPPS RCTs and the clinical efficacy,with the goal of providing clinical reference.A total of 466 related documents were retrieved in the search,and 62 articles were retained after screening.We obtained RCT information on acupuncture treatment of CP/CPPS.The results showed that several relevant clinical studies have been performed over the last 5 years and that acupuncture and moxibustion have better curative effect on CP/CPPS than WM.Due to the small number of included studies,more experimental evidence is needed to verify the clinical efficacy of acupuncture.

Boswellia resin extract and propolis derived polyphenols in patients with type III chronic prostatitis/chronic pelvic pain syndrome:An Italian prospective multicenter study

Objective:To assess the efficacy and safety of a treatment regimen based on rectal administration of Boswellia resin extract and propolis derived polyphenols in patients with type IIIa and type IIIb chronic prostatitis and chronic pelvic pain syndrome(CP/CPPS).Methods:Patients with type IIIa and type IIIb CP/CPPS received one rectal suppository a day for 15 days per month for 3 consecutive months.Participants were evaluated with National Institutes of Health-Chronic Prostatitis Symptom Index(NIH-CPSI),the International Prostate Symptom Scores(IPSS),International Index of Erectile Function(IIEF),four-glass test,uroflowmetry,and prostate-specific antigen assessments at baseline and at Week 4,and Week 12.Primary endpoints were improvement in pain domain of NIH-CPSI and improvement of NIH-CPSI total score.Secondary outcomes included improvement of micturition and quality of life(QoL)domains of NIH-CPSI questionnaire.Results:A total of 61 males were enrolled.No adverse events were reported.Significant improvements from baseline to Day 30 were reported for NIH-CPSI total score(mean difference:-9.2;p<0.01),NIH-CPSI pain domain(mean difference:-5.5;p<0.01),NIH-CPSI micturition domain,NIH-CPSI QoL domain,and IPSS total score(mean difference:-5.6;p<0.01).No significant changes from baseline in terms of IIEF score or maximum flow rate were observed.At final follow-up(Day 90),further significant improvements in terms of NIH-CPSI total score(mean difference:-12.2;p<0.01),NIH-CPSI pain domain(mean difference:-6.6;p<0.01),NIH-CPSI micturition domain,NIH-CPSI QoL domain,and IPSS total score were reported.Conclusion:Rectal administration of Boswellia resin extract and propolis derived polyphenols is well tolerated and delivers a significant symptomatic improvement in most patients with type IIIa and type IIIb CP/CPPS.

Updates on therapies for chronic prostatitis/chronic pelvic pain syndrome

Prostatitis comprises of a group of syndromes that affect almost 50% of men at least once in their lifetime and makeup the majority of visits to the Urology Clinics.After much debate, it has been divided into four distinct categories by National Institutes of Health namely(1) acute bacterial prostatitis;(2) chronic bacterial prostatitis;(3) chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS) which is further divided into inflammatory and non-inflammatory CP/CPPS; and(4)asymptomatic inflammatory prostatitis. CP/CPPS has been a cause of great concern for both patients and physicians because of the lack of presence of thoroughinformation about the etiological factors along with the difficult-to-treat nature of the syndrome. For the presented manuscript an extensive search on PubM ed was conducted for CP/CPPS aimed to present an updated review on the evaluation and treatment options available for patients with CP/CPPS. Several diagnostic criteria's have been established to diagnose CP/CPPS, with prostatic/pelvic pain for at least 3 mo being the major classifying symptom along with the presence of lower urinary tract symptoms and/or ejaculatory pain. Diagnostic tests can help differentiate CP/CPPS from other syndromes that come under the heading of prostatitis by ruling out active urinary tract infection and/or prostatic infection with uropathogen by performing urine cultures, Meares-Stamey Four Glass Test, Preand Post-Massage Two Glass Test. Asymptomatic inflammatory prostatitis is confirmed through prostate biopsy done for elevated serum prostate-specific antigen levels or abnormal digital rectal examination. Researchers have been unable to link a single etiological factor to the pathogenesis of CP/CPPS, instead a cluster of potential etiologies including atypical bacterial or nanobacterial infection, autoimmunity, neurological dysfunction and pelvic floor muscle dysfunction are most commonly implicated. Initially monotherapy with anti-biotics and alpha adrenergic-blockers can be tried, but its success has only been observed in treatment nave population. Other pharmacotherapies including phytotherapy, neuromodulatory drugs and anti-inflammatories achieved limited success in trials. Complementary and interventional therapies including acupuncture, myofascial trigger point release and pelvic floor biofeedback have been employed. This review points towards the fact that treatment should be tailored individually for patients based on their symptoms. Patients can be stratified phenotypically based on the UPOINT system constituting of Urinary, Psychosocial, Organ-specific, Infectious, Neurologic/Systemic and symptoms of muscular Tenderness and the treatment algorithm should be proposed accordingly. Treatment of CP/CPPS should be aimed towards treating local aswell as central factors causing the symptoms. Surgical intervention can cause significant morbidity and should only be reserved for treatment-refractory patients that have previously failed to respond to multiple drug therapies.

Treatment of Nonspecific Chronic Prostatitis with Qian Lie Xian Yan Suppository in 104 Cases

Qian Lie Xian Yan Suppository (前列腺炎栓) was rectally applied to treat 104 patients with nonspecific chronic prostatitis ( damp-heat syndrome with blood stasis) in contrast to 30 patients treated with traditional Chinese drug Ye Ju Hua Shuan (野菊花栓Suppository of Flos Chrysanthemi Indici). The results show that chronic prostatitis is markedly improved by using Qian Lie Xian Yan suppository, with a short-term cure rate of 23.1% and a total effective rate of 84.6%, superior to that of the control group. The animal experiment indicates that Qian Lie Xian Yan suppository has better anti-inflammatory and analgesic effects, with an action of promoting blood circulation.

Management of chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS):an evidence-based approach

Objective：To evaluate the efficacy and safety of the treatment of chronic prostatitis/chronic pelvic pain syndrome （CP/CPPS）. Methods- The randomized controlled trials （RCTs） about the treatment for CP/CPPS all over the world were searched. MEDLINE （January 1966 to June 2007）, EMBASE （January 1988 to June 2007）, and 4 Chinese databases were electronically searched. The studies included in the refer- ences of eligible studies were additionally searched. Two reviewers independently screened the studies for eli- gibility, evaluated the quality and extracted the data from the eligible studies, with confirmation by cross- checking. Divergences of opinion were settled by discussion or consulted by the experts. Meta-analysis was performed by using RevMan 4.2 software. Results： Twelve original studies involving 1 003 participants met inclusion criteria. Compared with placebo, alpha-blockers could improve the symptoms of CP/CPPS obvious- ly with WMD of NIH-CPSI, total score and pain score were -4.10 （95%CI： -6. 92 to -1.28） and -1.68 （95 %CI： -2.54 to -0. 82）. Antibiotics could not improve the symptoms obviously with WMD of NIH-CP- SI; total score and pain score were -2.71 （95%CI： -4. 78 to -0. 64） and -0.86 （95%CI： -2.07 to 0.36）. Flavoxate could not improve the NIH-CPSI total score obviously, but could relieve the pain, with WMD of NIH-CPSI total score and pain score being -2.96 （95%CI： -5.17 to -0. 74） and --2.31 （95%CI.. -4.05 to 0.03）. Prostat could improve the NIH-CPSI total score obviously, but could not relieve the pain, with WMD of NIH-CPSI total score and pain score being --7. 60 （95%CI.. -9. 97 to -5.23） and -2. 02 （95%CI： -4.07 to 0. 04）. Conclusion： Drug intervention could improve total symptoms of CP/CPPS in some degree, but no universally effective treatment is available that can prove significant lasting benefit for all the symptoms of CP/CPPS. Future RCT must use an appropriate sample size and optimal duration and fol- low-up of participants. It is important to improve the quality of internal original studies.

The clinical effects were also observed in a 4-week follow-up. Results:All but six cases completed the trial and the follow-up. It showed that in the treated group recovery rate was 17. 2%, markedly effective rate 34. 5%, effective rate 32. 8%, total markedly effective rate 51. 7%, and total effective rate 84. 5%, all of which were superior to those in the control group (total markedly effective rate 32.1% and total effective rate 66.1%, respectively), P<0. 01. Conclusion: Administration of QLA suppository via anal route combined with oral antibiotics is an effective therapy for chronic prostatitis syndrome. It can relieve the symptoms of chronic prostatitis syndrome markedly and rapidly. It is a new choice for treatment of the disease.

Study on the Mechanism of Angelica sinensis-Phellodendri Chinensis Cortex in the Treatment of Chronic Prostatitis Based on Network Pharmacology

[Objectives]To explore the mechanism of Angelica sinensis-Phellodendri Chinensis Cortex in the treatment of chronic prostatitis(CP)based on the method of network pharmacology.[Methods]The active components and action targets of Angelica sinensis-Phellodendri Chinensis Cortex were screened by(TCMSP),a systematic pharmacological analysis platform of traditional Chinese medicine,combined with literature search.The target was corrected by Uniprot database,and the disease CP target was screened by GeneCards and OMIM database.The common targets of drugs and diseases were screened by R language software,and the visual network map of drugs-active components-targets-diseases was constructed by Cytoscape 3.5.1 software.The common target protein-protein interaction(PPI)network was constructed by using STRING platform.The R language software was used to annotate and analyze the gene function and pathway of the core target through geneontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG).[Results]46 active components of Angelica sinensis-Phellodendri Chinensis Cortex were screened,and 212 related targets were predicted,of which 159 were related to disease.These targets were mainly involved in biological processes such as heterologous biological stimulation,oxidation and anti-oxidation,and were mainly concentrated in PI3K-Akt,mitogen-activated protein kinase(MAPK),hypoxia inducible factor-1(HIF-1)and other related signaling pathways.[Conclusions]The multi-component,multi-target and multi-pathway action characteristics of Angelica sinensis-Phellodendri Chinensis Cortex were confirmed by network pharmacology,and the possible mechanism of Angelica sinensis-Phellodendri Chinensis Cortex in the treatment of CP was predicted,which provided a theoretical basis for further experiments to verify its action mechanism.

Clinical classification of chronic prostatitis:a preliminary investigation

Aim: To propose a practical clinical classification for the chronic prostatitis (CP). Methods: The clinical fea-tures and the findings in the expressed prostatic secretion (EPS) in 804 cases of CP patients were retrospectively ana-lyzed. Results: Four types of CP were identified based on the clinical manifestations and the amounts of whiteblood cells (WBC) and lecithin in EPS. They were the latent type (85 cases; 10.6%), the common type (423 cases;52.6%), the persisting type (104 cases; 12.9%), and the active type (192 cases, 23.9%). The therapeutic efficacyfor these 4 subtypes were 40.4%, 76.8%, 30.8% and 37%, respectively; a statistical difference was noticed be-tween the common type and the persisting type (P < 0.01 ). Conclusion: The method of classification proposed bythe authors may help clinicians in the diagnosis and predicting the prognosis of CP. (Asian J Androl 2000 Dec; 2:311-313)

Berberine hydrochloride alleviates chronic prostatitis/chronic pelvic pain syndrome by modifying gut microbiome signaling

Chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS)is highly prevalent worldwide and poses a significant threat to men’s health,particularly affecting young men.However,the exact causes and mechanisms behind CP/CPPS remain unclear,leading to challenges in its treatment.In this research,a CP/CPPS rat model was established with complete Freund’s adjuvant(CFA),and berberine hydrochloride was administered through daily gavage to assess its therapeutic effects.The alterations in the gut microbiome induced by CP/CPPS and berberine hydrochloride were investigated through 16S ribosomal RNA sequencing of cecum content and colonic epithelial cells.To investigate the impact of the gut microbiome on CP/CPPS,a pseudo germ-free rat model was established,and fecal microbiome transplantation(FMT)was performed on these rats.In all,berberine hydrochloride demonstrated effective reduction of inflammation and oxidative stress in the prostate,offering significant therapeutic advantages for CP/CPPS.Through analysis of the gut microbiome using 16S ribosome RNA sequencing,distinct differences were observed between CP/CPPS rats and control rats,and Clostridium butyricum was identified as a key bacteria.Pseudo germ-free rats that underwent FMT from CP/CPPS rats or rats treated with berberine hydrochloride displayed varying levels of inflammatory cytokine production,oxidative stress,and activity of associated signaling pathways.In conclusion,the therapeutic potential of berberine hydrochloride in addressing CP/CPPS is highly significant.The gut microbiome has emerged as a critical factor in the development of CP/CPPS and plays a pivotal role in mediating the therapeutic effects of berberine hydrochloride.

Clinical Analysis of Acupuncture Combined with Acupoint Injection for the Treatment of Chronic Nonbacterial Prostatitis

Objective:To evaluate the therapeutic effect of acupuncture combined with acupoint injection on chronic nonbacterial prostatitis(CNP).Methods:A total of 72 CNP patients admitted between March 2022 and October 2023 were selected.The patients were randomly divided into two groups using a random number table.The combined treatment group(36 cases)received acupuncture combined with acupoint injection therapy,while the control group(36 cases)received conventional Western medicine treatment.The overall efficacy rate,symptom severity,prostatic fluid indicators,incidence of adverse reactions,and recurrence rates were compared.Results:The overall efficacy rate of the combined treatment group was higher than that of the control group(P<0.05).After 10 days of treatment,the symptom severity score of the combined treatment group was higher than that of the control group,and the prostatic fluid indicators were lower than those of the control group(P<0.05).The incidence of adverse reactions in the combined treatment group was lower than in the control group(P<0.05).During the follow-up period of 1-6 months,the recurrence rate in the combined treatment group was lower than that in the control group(P<0.05).Conclusion:Acupuncture combined with acupoint injection can alleviate CNP disease symptoms,improve prostate function,and prevent post-treatment adverse reactions.It also has a lower recurrence risk and demonstrates excellent efficacy.

Molecular mechanism and promising treatments of chronic prostatitis/chronic pelvic pain syndrome:An exploratory bibliometric analysis and literature review of preclinical studies

Background:As one of the most common diseases in urology,a large number of preclinical studies have been accumulated to explore the etiological mechanism and potential intervention of chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS).Methods:In this study,we systematically evaluated the current status of preclinical research on CP/CPPS through bibliometrics analysis using VOSviewer and Citespace.Characteristics of publication such as year,country/region,institution,author,journal,citation,and keywords were analyzed.Based on the bibliometrics analysis results of keywords,we summarized the possible mechanisms and promising treatments for CP/CPPS narratively.Results:According to the results of this study,the most common mechanisms involved in CP/CPPS were as follows:Disturbed immune and inflammation mediators,immune cell dysfunction,oxidative stress,dysregulated signaling pathways,apoptosis,gut microbiota,and testosterone metabolism.Traditional Chinese Medicine and extracorporeal shock wave therapy have important potential in the treatment of CP/CPPS.Conclusion:Further translational studies targeting the above mechanisms and validating the objective efficacy of potential treatments indicated by preclinical studies in clinical patients are needed in the future.

Research progress of miRNA and chronic nonbacterial prostatitis

Chronic nonbacterial prostatitis(CNP),also the typeⅢprostatitis account for more than 90%of all patients with prostatitis.It has a long course of disease,easy to repeat,unknown pathogenesis and poor clinical efficacy.At present,some scholars at home and abroad have found that there is differential expression of microRNA(miRNA)in prostatic fluid of CNP patients or prostate tissue of CNP rat model.Intervention of miRNA expression can alleviate the symptoms and pharmacodynamics of CNP to a certain extent,which opens up a new way and direction for the pathogenesis and diagnosis and treatment of CNP.Therefore,this paper reviews the research progress of miRNA and CNP in recent years.

A comparative study of two methods for establishing a chronic non‑bacterial prostatitis model in rats‑

Objective:To compare the biological characteristics and stability of the chronic non-bacterial prostatitis(CNP)model in rats induced by the depot combined with estrogen induction method and the autoimmune response induction method.Methods:The CNP rat model was prepared using the depot combined with 17β-estradiol induction method in the depot hormone group and three concentrations of prostate protein homogenate at 40 mg/mL,20 mg/mL and 10 mg/mL in the autoimmune group,respectively.The degree of prostate tissue damage was evaluated by pathology(HE staining),and the immunoturbidimetric method was used to evaluate the contents of immunoglobulins IgA,IgM and IgG.ELISA was used to evaluate interleukin-1β(IL-1β),interleukin-10(IL-10),tumor necrosis factor-α(TNF-α)and high-sensitivity-C-reactive protein(hs-CRP),and electrochemiluminescence was used to evaluate the expression level of testosterone(T),and the two model methods were compared.Results:Compared with the sham-operated group,the body mass of rats in both models was significantly lower in the depot hormone group and autoimmune group before extraction(P<0.01,P<0.01),and histopathology of the prostate in both models showed destruction of glandular structure and a significant increase in inflammatory cells.Compared with the depot hormone group and the autoimmune group,the histopathological changes and inflammatory pathological scores of prostate and the contents of immune indexes IgA,IgM and IgG were significantly different in the depot hormone group(P<0.05,P<0.05,P<0.05),and the levels of IL-1β,IL-10,TNF-α,hs-CRP and T were significantly changed in the autoimmune group(P<0.01).The comparison between the high,medium and low dose groups of the autoimmune group,in which the pathological changes in the medium dose of the autoimmune group were slightly better than the other two groups between the groups,but the changes in IL-1β,IL-10,TNF-α,hs-CRP,and T in the low dose of the autoimmune group were the most significant(P<0.05).Conclusion:The pathological tissues of the chronic non-bacterial prostatitis model established by the depot combined with estrogen induction method and the autoimmune response induction method both showed significant changes,and the comprehensive indexes indicated that the depot combined with estrogen induction method was a more appropriate modeling choice.
