[Expression of ARA55 mRNA in prostate carcinoma tissues and its significance].

Objective: To investigate the expression of ARA55 mRNA in the prostate carcinoma tissues and its clinical significance.

Methods: Real-time RT-PCR was used to examine the expression of ARA55 mRNA in the samples of the prostate carcinoma tissues from 32 patients.

Results: ARA55 mRNA expressed in different degrees in all the samples.

[Update of the relationship between erectile dysfunction and endothelial function].

Endothelial function plays a very important role in the process of erection. Erectile dysfunction (ED) and coronary artery disease (CAD) overlap in risk factors, aetiology and clinical outcomes. Endothelial dysfunction is considered to be their shared aetiological factor.

[Protective effects of vasoactive intestinal peptide on septic shock rats].

Objective: To investigate the protective effects of vasoactive intestinal peptide (VIP) on septic shock rats and explore its possible mechanism.

Methods: Cecal ligation and puncture (CLP) was performed to produce septic shock rat model. Thirty adult Sprague-dawley rats were randomly divided into 3 groups with 10 animals in each group: sham operation group, CLP group and VIP group.

[IIEF-5 cannot be used as a tool for differential diagnosis of vasculogenic erectile dysfunction].

Objective: To evaluate the 5-item version of the international index of erectile function (IIEF-5) as a method to differentiate the causes of vasculogenic erectile dysfunction (ED).

Methods: In all, 103 ED patients (mean age 46.8 +/- 18.
