MicroRNA-128 (miR-128) has been identified as a negative regulator of malignant phenotypes of prostate cancer (PCa) cells. The aim of this study was to evaluate the prognostic implications of both tissue and serum levels of miR-128 expression in PCa patients undergoing radical prostatectomy.A series of 128 cases with PCa were evaluated for both tissue and serum levels of miR-128 expression by quantitative reverse-transcription PCR.Compared with non-cancerous prostate tissues and normal sera, both tissue and serum levels of miR-128 expression were significantly decreased in PCa patients (both P<0.001). Importantly, there was a close correlation between tissue and serum levels of miR-128 expression in PCa patients (rs=0.808, P<0.001). Then, low miR-128 expression in both PCa tissues and patients sera were dramatically associated with aggressive clinicopathological features, including advanced pathological stage (both P=0.001), positive lymph node metastasis (P=0.006 and 0.01, respectively), high preoperative PSA (both P=0.01) and positive angiolymphatic invasion (both P=0.02). Moreover, Kaplan-Meier survival analysis showed that low miR-128 expression in both PCa tissues and patients sera were significantly associated with short biochemical recurrence (BCR)-free survival. Furthermore, multivariate analysis indicated that both tissue and serum levels of miR-128 expression were independent prognostic factors for BCR-free survival of PCa patients.Our data suggest that the decreased expression of miR-128 in both tissue and serum samples of PCa patients may be associated with tumor malignant progression and BCR-free survival. Particularly, serum miR-128 may be developed as a novel noninvasive biomarker for PCa diagnosis and prognosis.

Autologous implantation of bone mesenchymal stem cells (BMSCs) has achieved promising clinical efficacy for the treatment of early-stage osteonecrosis of the femoral head (ONFH). However, the underlying mechanisms are not completely elucidated. Here, we investigated the effect of BMSCs on the early ONFH in vitro and in vivo. In co-cultured system, primary BMSCs enhanced the activity and inhibited the apoptosis of primary OB. The concentrations of VEGF and BMP-2 in the co-cultured medium were significantly higher than those without co-culture. Importantly, BMSCs implantation increased OB, capillaries and VEGF and BMP-2 expressions of the necrotic areas of femoral head in the ONFH rabbits. In conclusion, our results indicated that BMSCs treated the early ONFH possibly through increasing OB and capillaries, as well as VEGF and BMP-2 expression in the femoral head. These results provided possible mechanisms for the treatment of early-stage ONFH with BMSCs transplantation.
