ABSTRACT
OBJECTIVE:
To investigate the changes in the topological properties of the global and local nodal efficiencies of the brain white matter network in patients with type III B prostatitis, and to analyze the correlation between the information transmission efficiency of different brain regions and pelvic pain.METHODS:
We enrolled 19 patients with type â ¢ B prostatitis and 32 normal controls matched in general demographic data for this study. We assessed the pelvic pain of the patients based on the NIH-CPSI, obtained the structural and diffusion-weighted MR images of the brain, preprocessed the MRI data, constructed the brain structural networks and calculated the topological properties of the nodal local and global efficiencies using the FSL software package and brain connection toolbox. Finally, we compared the topological properties between the two groups by t-test with the SPSS 20 software, performed multiple correction of the values using the false discovery rate (FDR) method, and investigated the associations of the altered brain regions with the NIH-CPSI scores by Pearson correlation analysis.RESULTS:
The global efficiency of the orbital part of the right median frontal gyrus in the patients with type â ¢ B prostatitis, compared with that in the normal controls, was dramatically decreased (0.095 ± 0.046 vs 0.13 ± 0.015, P < 0.01) while that of the left median cingulate gyrus markedly increased (0.16 ± 0.027 vs 0.14 ± 0.019, P < 0.01), which were corrected by FDR. The local efficiency of the left median cingulate gyrus was also remarkably decreased in the patients as compared with that in the controls (0.25 ± 0.075 vs 0.19 ± 0.036, P < 0.01), and so was that of the left paracentral lobule (0.25 ± 0.088 vs 0.17 ± 0.065, P < 0.01), which were corrected by FDR. In the patients, the local efficiencies of the left precuneus (r = 0.46, P = 0.045), right supplementary motor area (r = 0.47, P = 0.043) and left median cingulate gyrus (r = 0.60, P = 0.0065) were positively correlated with the total score of NIH-CPSI, the scores of pain and discomfort symptoms, and the scores of the influence of the symptoms on the quality of life.CONCLUSIONS:
The changes of the brain regions in the executive control network of the patient with type â ¢ B prostatitis might be involved in enhancing his sensitivity to pain and discomfort, and consequently lead to pelvic pain and discomfort.Palavras-chave
