[Correlations between resting-state brain functional characteristics and TCM syndrome in premature ejaculation patients with heart-kidney disharmony].

Objective: To investigate the correlation between the characteristics of resting-state brain function and the types of traditional Chinese medicine (TCM) syndrome in premature ejaculation (PE) patients with heart-kidney disharmony, and the pathogenesis of abnormal ejaculation of the patients.

Methods: We enrolled 33 PE patients with heart-kidney disharmony and 32 healthy controls matched in general demographic data, evaluated the severity of the main and concurrent symptoms of PE using the PE Diagnostic Tool (PEDT) and TCM Syndrome Scale (TCMSS), and obtained the brain structural and functional MRI data. We processed the collected data and calculated the amplitude of low-frequency fluctuations (ALFF), fractional ALFF (fALFF) and regional homogeneity (Reho) of the brain with the DPABI software.

[Psychological factors and penile blood supply in patients with erectile dysfunction].

Objective: To explore the psychological factors and blood supply to the penis in ED patients.

Methods: From August to November 2018, we obtained Symptom Checklist 90 (SCL-90) scores and conducted an Eysenck Personality Questionnaire (EPQ) investigation among 106 ED patients in our Department of Andrology, followed by the test of intracavernosal injection of the vasoactive agent (ICI-VAA) and color duplex Doppler ultrasonography (CDDU). According to the results of ICI-VAA and CDDU, we divided the patients into a normal and an abnormal group, compared their item and total scores on SCL-90 with the national norm by t-test and analyzed the distribution of personality types in different groups by Chi-square test.
