However, implants in patients with type 2 diabetes mellitus are likely to have a high failure rate and poor initial osseointegration. In the current study, we established an effective drug delivery system designed to(More)
OBJECTIVE To determine the levels of MMP-2 and COX-2 mRNA in bladder transitional cell carcinoma tissues and explore their relationship. METHODS We enrolled in this study 42 patients with bladder transitional cell carcinoma, including Ta-T1 (n = 18), T2-T4 (n = 24), G1 (n = 12), G2 (n = 19), G3 (n = 11), metastasis (n =26) and non-metastasis (n = 16).(More)
OBJECTIVE To evaluate the effect of sustained release of recombinant rat insulin-like growth factor-1(rrIGF-1) from poly (lactide-CO-glycolide) (PLGA) microspheres on bone formation in the peri-implant areas in Goto-Kakizaki rats with type 2 diabetes. METHODS Type 2 diabetes models were successfully established in 20 male Goto-Kakizaki rats, which were(More)
OBJECTIVE To explore the relationship between the expression of caspase-3 in testicular germ cells of rats with experimental left varicocele (ELV) and apoptosis of germ cells. METHODS Twenty-four male SD rats were randomly divided into three groups with eight animals each: sham-operation group (SOG), 30-day post-operation group (PG1) and 60-day(More)
