Summary

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is one of the most common diseases in urology, but its pathogenesis remains unclear and the effective therapy lacks. As a kind of chronic pain which the patients suffered for more than 3 months, CP/CPPS could be alleviated by acupuncture. Functional magnetic resonance imaging (fMRI) and higher magnetic field strengths could enable scientists to investigate the brain accurately and non-invasively during every stage of chronic pain.To avoid placebo effect, sham acupuncture would be also enrolled.Herein, by the utilization of fMRI in resting-state, we investigated the influence on patients' brain alterations after the patients accepted the treatment of acupuncture.

Detailed description

A two (participant and assessor) blind, two-arm parallel, randomized controlled trial will be conducted. Sixty patients with CP/CPPS will be recruited from Huashan Hospital, Shanghai, and thirty healthy volunteers will be recruited as the healthy control group by advertisement. Patients will be randomly assigned into one of two intervention groups: acupuncture group and sham acupuncture group. The ratio of healthy control (n = 30), acupuncture group (n = 30) and sham acupuncture group (n = 30) will be 1:1:1. Sanyinjiao (SP6), Zhibian (BL54), Shenshu (BL23), and Huiyang (BL35) are chosen as acupoints for both acupuncture group and sham acupuncture group (Park sham device). The course of treatment is 2 times a week in three months (totally 24 times). The group of healthy control will get only once fMRI scan while the group of patients will get fMRI scan week 0 (before treatment), week 12 (after treatment) and week 36 (following up). Every time the participants receive the fMRI scan, they will be asked to finish the clinical scales. The primary outcome will be the change in the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) total score from baseline to week 12 and week 36. Secondary outcomes will include the changes of Hospital Anxiety and Depression Scale, International Prostate Symptom Score, International Index of Erectile Function, Self-Esteem Scale, Social Support Rating Scale and Numeric Rating Scale and brain functional activated or inactivated regions.

Conditions

• Chronic Prostatitis With Chronic Pelvic Pain Syndrome

Interventions

Type	Name	Description
DEVICE	Acupuncture	Hwato brand disposable acupuncture needles (size 0.30 × 75mm; size 0.30 × 40mm) will be used.SP6 is on the tibial aspect of the leg, posterior to the medial border of the tibia, 3 cun superior to the prominence of the medial malleolus; BL23 is in the sacral region, in the second posterior sacral foramen; BL54 is in the fourth posterior sacral foramen, 3 cun beside the median sacral crest; BL35 is in the buttock region, 0.5 cun lateral to the extremity of the coccyx.
DEVICE	Sham acupuncture	Hwato brand disposable acupuncture needles (size 0.30 × 75mm; size 0.30 × 40mm) will be used.These volunteers will receive relatively shallow needling at bilateral sham SP6, BL54, BL23 and BL35. This treatment gets involved in the same duration and frequency of sessions, but the treatment was delivered superficially at non-acupuncture points 10 mm to the lateral of corresponding acupuncture and not above a meridian line (10mm to SP6, BL54, BL23 and BL35).The same equipment of fMRI scanner will be used.
OTHER	fMRI scan	Both two group will get fMRI scan week 0 (before treatment), week 12 (after treatment) and week 36 (following up). The resting-state fMRI data will be obtained by using a 3.0T GE MR 750 MRI scanner with an eight-channel phase array head coil at the Huashan Hospital, Shanghai. The high resolution T1-weighted magnetic resonance images will be collected by a three-dimensional fast spoiled gradient-echo dual-echo sequence \[repetition time (TR) = 8100 ms; echo time (TE) = 3.1 ms; FA = 8 deg; matrix=256 × 256; field of view (FOV)=25.6× 25.6 cm2; slice thickness=1 mm; no gap and 156 slices\]. The whole resting state fMRI data will be acquired by using a gradient-recalled echo-planar imaging pulse sequence (TR/TE = 2,000/30 ms; FA = 90°; acquisition matrix = 64×64; FOV = 22×22 cm2; slice thickness= 4 mm; 43 slices and total 240 time points; no gap).
