    ABSTRACT: To evaluate the effects of improved experimental left varicocele (ELV) on follicle-stimulating hormone (FSH) and inhibin B (InhB). ELV models were established by the improved method in 30 SD rats, and another 30 were included in a sham operation group as controls. Three months after the operation, the concentrations of the FSH and InhB were assayed by ELISA. The concentration of FSH in the serum was significantly higher in the experimental group ([37.56 +/- 9.72] ng/ml) than in the control ([26.69 +/- 5.33] ng/ml) (P < 0.05), while that of InhB significantly lower in the former ([349.93 +/- 99.48] pg/ml) than in the latter ([768. 83 +/- 146.96] pg/ml) (P < 0.05). Improved ELV can increase FSH and reduce InhB in rats, which may be associated with subfertility.

    ABSTRACT: To evaluate the mitochondrial function score in combination with Gleason score in predicting the progression of prostate cancer. This study included twenty 58-79 (70.1 +/- 1.2) years old patients with prostate cancer treated by radical prostatectomy. The epithelioglandular mitochondrial function scores of the patients were obtained under the transmission electron microscope and assessed according to Flameng grading. Meanwhile, their Gleason scores were analyzed and, based on the scores, the patients were divided into Groups I (Gleason score: 2 -4) and II (Gleason score: 5 -7). The mitochondrial function score of Group I was significantly different from that of Group II (4.0 +/- 0.8 versus 2.3 +/- 0.6, P < 0.05), with a negative correlation with the Gleason score (r = -0.793, P < 0.05). One year follow-up showed a significantly lower mortality in Group I (0/8) than in Group II (6/12) (P < 0.05). Mitochondrial dysfunction exists in prostate cancer patients, particularly in those with higher malignancy. The mitochondrial function score combined with Gleason score plays a valuable role in predicting the progression of prostate cancer.
