Background: von Willebrand Factor (vWF) and fibrinogen (Fb) are associated with hypercoagulability and thrombosis, which are the pathology and symptom of arterial disease. This research aims to study the effects of endovascular interventions on blood vWF and Fb levels in patients with diabetic peripheral artery disease (PAD).
Methods: Totally, 66 type 2 diabetic patients with PAD (intervention group) and 26 type 2 diabetic patients without PAD (control group) were enrolled.
[Changes in prostatic stromal composition and benign prostatic hyperplasia].

Objective: To investigate whether there are different stromal compositions in the prostate tissue of patients with benign prostatic hyperplasia (BPH) and evaluate their significance in the course of the disease.
Methods: Forty-three surgical or bioptic prostatic specimens of BPH and 5 autoptic normal prostatic specimens were stained by the Masson method to display the elements of the muscle fiber and collagen. The relationship of the changes in the prostatic stromal composition was analyzed with the degree of bladder outlet obstruction (BOO) , IPSS and medication results.
Background: There are no reports regarding voiding/retrograde urethrography with 64-row multidetector CT (64-MDCT).To compare the clinical relevance of conventional voiding/retrograde urethrography and 64-MDCT urethrography for the evaluation of male posterior urethral stricture.
Methods: From January to October 2009, 21 men were referred to our institution for the management of posterior urethral stricture.
Objective: To evaluate the correlation between arteriosclerotic risk factors and the severity of benign prostatic hyperplasia (BPH).
Methods: A total of 877 patients with diagnosed BPH were selected according to the inclusion criteria. The weight of the prostate was estimated by transrectal ultrasonography, the degree of bladder outlet obstruction determined by urodynamic examination, and the symptoms quantified by the International Prostate Symptom Score (IPSS).
Objective: To elucidate the relation of platelet-derived growth factor receptor (PDGFR) and c-Fos protein expressions with human bladder transitional epithelial cell carcinoma (BTCC).
Methods: The expressions of PDGFR and c-Fos were investigated in 11 normal bladder tissue samples, 14 adjacent non-carcinoma tissues and 43 BTCC tissues by means of SP immunohistochemical technique.
Results: The c-Fos expression was found in the cell nuclei and cytoplasm, and PDGFR in the nuclear membrane, cytoplasm, and cellular membrane.
[Comparative anatomical study of three surgical approaches for treating complex posterior urethral stricture].
Di Yi Jun Yi Da Xue Xue Bao

Objective: To evaluate the advantages and disadvantages of 3 surgical approaches via superior intermedial margin of the pubis, inferior medial margin of the pubis, and the perineum, respectively, in the treatment of posterior urethral stricture.
Methods: Thirty-five adult male corpses were dissected in which the distances from the bulbo-membranous urethra conjunction (D), the apex of prostate (E), and the bladder neck (F) to the superior medial margin of the pubis (A), the inferior medial margin of the pubis (B) and the midpoint of linear distance between the two ischial tuberosities on the perineum (C) were respectively measured and compared. Another 20 adult male corpses were subjected to the 3 surgical approaches as described above and the urethra was exposed to identify the tissues and organs with possible injuries resulted from the surgery, which were evaluated by scoring.
