<p><b>OBJECTIVE</b>To prepare and characterize a nano-scale fibrous hydrophilic poly-L-lactic acid/ Bioglass (PLLA/BG) composite membrane and evaluate its biocompatibility as a composite membrane for guiding bone regeneration (GBR).</p><p><b>METHODS</b>PLLA/BG-guided bone regeneration membrane was treated by oxygen plasma to improved its hydrophilicity. The growth of MG-63 osteoblasts on the membrane was observed using Hoechst fluorescence staining, and the biocompatibility of the membrane was evaluated by calculating the cells adhesion rate and proliferation rate. Osteogenesis of MG-63 cells was assessed by detecting alkaline phosphatase (ALP), and the formation of calcified nodules and cell morphology changes were observed using scanning electron microscope (SEM).</p><p><b>RESULTS</b>The cell adhesion rates of PLLA/BG-guided bone regeneration membrane treated with oxygen plasma were (30.570±0.96)%, (47.27±0.78)%, and (66.78±0.69)% at 1, 3, and 6 h, respectively, significantly higher than those on PLLA membrane and untreated PLLA/BG membrane (P<0.01). The cell proliferation rates on the 3 membranes increased with time, but highest on oxygen plasma-treated PLLA/BG membrane (P<0.01). Hoechst fluorescence staining revealed that oxygen plasma treatment of the PLLA/BG membrane promoted cell adhesion. The membranes with Bioglass promoted the matrix secretion of the osteoblasts. Under SEM, the formation of calcified nodules and spindle-shaped cell morphology were observed on oxygen plasma-treated PLLA/BG membrane.</p><p><b>CONCLUSION</b>Oxygen plasma-treated PLLA/BG composite membrane has good biocompatibility and can promote adhesion, proliferation and osteogenesis of the osteoblasts.</p>

<p><b>OBJECTIVE</b>To compare the clinical effects of transurethral detaching resection (TUDRP) and plasmakinetic transurethral resection of the prostate (PKRP) for benign prostatic hyperplasia (BPH).</p><p><b>METHODS</b>We collected by the single blind method the clinical data of 81 cases of BPH treated by PKRP (n=41) and TUDRP (n=40), and compared the two groups of patients in their age, preoperative prostate volume, weight of the resected gland, operation time, intraoperative bleeding, time of postoperative Foley's catheter retention, and pre- and post-operative IPSS.</p><p><b>RESULTS</b>The post-operative IPSS was significantly higher in the PKRP than in the TUDRP group (9.95 +/- 1.54 vs. 8.70 +/- 1.13, t = 0.0029, P = 0.0059).</p><p><b>CONCLUSION</b>TUDPR has a better clinical effect than PKRP in the treatment of BPH.</p>

<p><b>OBJECTIVE</b>To investigae the function of the glass colorant on the color of the machinable infiltrated ceramics(MIC).</p><p><b>METHODS</b>Five kinds of glass with different colorant were infiltrated through the aluminous matrix by heating the components to 1 100 degrees C for 2 hours. The specimens surface was polished, and their thickness was 0.5 mm.</p><p><b>RESULTS</b>The refractive index of the MIC infiltration glass was 1.59691 (587.6 nm, nd) . The most different parameter of the MIC color were L*, then a*, and b* had little difference . The parameters of the color space of MIC were: L*(64.55-71.46), a*(3.35-7.38), b*(10.00-12.41), Ca*b*(11.38-13.95), ha*b*(54.07-73.00). These were almost close to the color parameters of Vita In-ceram.</p><p><b>CONCLUSION</b>This experiment proved that the glass colorant was changed the MIC color parameters, and the main function was on L*, then a*. The ceramic color was up to the requirement of clinic.</p>
