[Prostatitis studies in China from 2000 to 2020: A Knowledge Atlas-based study on the development trend of contemporary disciplines].

OBJECTIVE: To review and analyze the trend of researches on prostatitis in China in the past two decades. METHODS: We searched the core collection of China National Knowledge Infrastructure (CNKI) for studies on prostatitis, and analyzed the data obtained using Excel, Citespace and VOSviewer. RESULTS: Totally, 1 216 original articles were identified, with 3 271 keywords, ≥3-time high-frequency keywords accounting for 12.9%, with "", "", "chronic prostatitis", "prostatitis", and "" as the top 5 ones, each with a centrality higher than 300. Major prostatitis-related studies focused on the 8 keywords, namely, prostatitis, prostatic fluid, rats, prostate, syndromes, efficacy observation, compound (in traditional Chinese medicine, TCM), and therapeutic application. The included literature involved 2 808 authors, with 402 involved more than twice and most of them in a scattered manner. The major topics of prostatitis studies varied in the past two decades, focusing on TCM therapies, promotion of blood circulation and stasis and comprehensive nursing in 2000－2001, on animal models, CD4+ lymphocytes and other experimental molecules in 2007－2010, on urodynamics, risk factors and specific antigens in 2013－2016, and on literature information resources in 2016. CONCLUSIONS: The immune mechanism remains a hot topic in the future researches on prostatitis. In terms of treatment of the disease, TCM has a potential value, and more practice and studies are required for an optimal combination of TCM and Western medicine. Strengthened collaborative efforts are needed to establish an authoritative source channel for the keywords, and incorporate it into the national standard system, and above all, to integrate the prostatitis study into multi-disciplinary researches, eliminate academic barriers, encourage collaborative innovation with multiple parties, and promote the exchanges and development in this field.

Effect of acupuncture on clinical symptoms and laboratory indicators for chronic prostatitis/chronic pelvic pain syndrome: a systematic review and meta-analysis.

OBJECTIVES: To systematically review the efficacy and safety of acupuncture for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). METHODS: PubMed, Cochrane library Central, Web of Science, Wang-fang Database, and CNKI were searched from their inception to June 30, 2016. Data of acupuncture for CP/CPPS following randomized controlled trials (RCTs) was included. The data were analyzed using the Cochrane Collaboration Review Manager. The primary data were the National Institute of Health-Chronic Prostatitis Index (NIH-CPSI) score at the end of follow-up. RESULTS: Ten RCTs were enrolled. Acupuncture was superior to the control in NIH-CPSI (MD -3.98, [95 % CI -5.78 to -2.19]; P < 0.0001) and response rate (RR 4.12, [95 % CI 1.67-10.18]; P = 0.002). Acupuncture was superior to sham acupuncture on NIH-CPSI, response rate, pain, urinary, and quality of life (QOL). Standard medication was inferior to acupuncture in terms of NIH-CPSI (MD -3.08, [95 % CI -5.57 to -0.60]; P = 0.02) and response rate (RR 2.03, [95 % CI 1.04-3.97]; P = 0.04), but standard medication was superior to acupuncture on improving urinary symptoms. There was no significant difference in the adverse events. Acupuncture/acupuncture plus standard medication significantly down-regulated IL-1ß compared with standard medication in prostatic fluid. CONCLUSION: Acupuncture treating CP/CPPS is effective and safe. The effects of acupuncture on NIH-CPSI, response rate, pain symptoms, and QOF were superior to the control, but standard medication significantly improved urinary symptoms compared with acupuncture. Acupuncture can decrease the IL-1ß in prostatic fluid for CP/CPPS.

[Biofeedback therapy for chronic prostatitis: Application and consideration].

Studies of biological feedback (BF) for the treatment of chronic prostatitis (CP) are occasionally reported have exhibited some related problems. This article presents an evaluation of the published literature on the BF treatment of CP at home and abroad in the aspects of instrument, method, application, effect, function, and mechanism. UROSTYMTM and MyoTrac are often employed and their operating paths are basically the same. NIH prostate symptom scores, urinary function, pain, sexual function, immune function, prostate fluid, and other indicators are generally used for the analysis of the effects of BF alone or in combination with other therapies on CP and its related symptoms. Either BF alone or BF combined with other therapies can promote urination, reduce pain, improve the quality of life, attenuate inflammation, improve sexual function, adjust immunity, and lessen physical and chemical stimulation. However, the relevant literature is of low quantity and quality, the reported studies are not standardized, and exploration of the action mechanisms is neglected.
