BACKGROUND: Microarc oxidation (MAO) is a break-through anodyzing technology for forming oxide films on valve metal.Use of this technology allows thick, porous oxide layers to be formed on the surface of pure titanium. Few biocompatibility reports using this treatment have been found.OBJECTIVE: The blood compatibility of a novel surface modified titanium substrata biomaterial using MAO was investigated.DESIGN: Positive and negative control, contrast observation and gold standard control.SETTING: Wuhan Union Hospital.MATERIALS: A healthy male adult New-Zealand rabbit, weighing 2.5 kg and ordinary grade, was selected in this study.Pure titanium sticks TA1 (Baoji Yingnaite Non-ferrous Metal Co., Ltd.), MAO-Ti and 20 g/L potassium oxalate were also selected in this study.METHODS: The study was carried out in the Laboratory of General Surgery, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology in May 2006. ① Materials: Titanium substrate of 10 mm in diameter and 2 mm in depth was put in an electrolyte which was quipped with deionized water, dibasic sodium phosphate, and ethanoic acid calcium for MAO treatment for 10 minutes. ② Groups: Three groups were analysed: test group, negative control group and positive control group. Test group: MAO-Ti was dipped in 10 mL saline; Positive control group: 10 mL deionized water was added in each tube; Negative control group: 10 mL saline was added in each tube. ③ Operation: Fresh whole blood was collected from rabbit and then mixed with the liquids in the three groups respectively after anti-coagulation. In addition, UV-Visible Spectrophotometer was used to evaluate the hemolytic ratio. A hemolytic ratio below or equal to 5% indicated that this novel material fitted the requirements. On the contrary, a hemolytic ratio higher than 5% proofed the existence of a hemolyzation.MAIN OUTCOME MEASURES: The hemolytic ratio of materials in three groups.RESULTS: The hemolytic ratio of the test group was 0.90%. The result indicated that this new material had no haemolysis effect.CONCLUSION: The material does not resolve red blood cells and is coincident with the international and governmental standard.

Objective To explore the intervention effect of emodin on organophosphorus poisoning induced respiratory failure.Methods 60 male Wistar rats of clean grade were randomly divided into:normal control group, model control group, positive drug group and emodin group, with 15 rats in each group.Except the normal control group rats were given intraperitoneal anesthesia, the right common carotid artery intubation, when rats stayed awake began a septic model.Blood gas analysis and serum level of oxygen free radicals and respiratory rate were compared before poisoning, respiratory failure, intervention of 5, 10, 30 min.Results Mouth breathing, slow respiratory frequency and cyanosis, appeared after exposure.Respiratory frequency decreased after exposure , compared with the positive drug group, respiratory frequency of emodin group 10 min and 30 min was higher ( P<0.05), PaO2, SaO2, BE decreased, PaCO2 increased after respiratory failure, Compared with the positive drug group, PaO2, PaCO2, SaO2 and BE of emodin group for the treatment of 10 min, 30 min was higher,(P <0.05).The level of oxygen free radicals in rats of each group had no significant difference before the exposure and the respiratory failure.Compared with the positive drug group, SOD and MDA of emodin group in 30 min after intervention were higher,( P<0.05 ) .Conclusion Emodin can improve the respiratory frequency of organic phosphorus poisoning induced respiratory failure ,improve blood gas analysis of the indicators and the level of oxygen free radicals.

The presence of insufficient bone volume affects the implant healing and success. The aim of this study was to evaluate osteogenic capacity of dental pulp stem cells (DPSCs) on micro-arc oxidation (MAO) titanium surface. DPSCs were challenged at MAO and smooth titanium surface separately for different durations, and the bone marrow mesenchymal stem cells (BMSCs) served as the positive controls. The osteogenic capacity of DPSCs on MAO titanium surface was assessed by using scanning electron microscopy, energy dispersive spectroscopy, biochemical tests and real-time quantitative PCR. Data showed that DPSCs differentiated into osteoblasts and expressed bone morphogenetic genes on MAO titanium surface. The results of this study revealed that DPSCs had good potential to generate mineralized tissue on MAO titanium plates. The differential potential of DPSCs may be regulated by MAO titanium surface. The osteogenesis potential of DPSCs on the MAO titanium was similar with BMSCs.

BACKGROUND:Osteoporosis caused by chemotherapy has become one of the serious side effects that impact the skeletal system. Icarin shows a strong anti-osteoporosis activity, which can have protective effect on osteoporosis induced by chemotherapy. OBJECTIVE: To study the protective effect and mechanism of icarin against cyclophosphamide-induced obstacle of mouse bone marrow mesenchymal stem cels differentiating into osteoblasts. METHODS:MTT assay and alkaline phosphatase (ALP) staining were used to determine the optimal protective concentration of icarin against cyclophosphamide-induced obstacle of mouse bone marrow mesenchymal stem cels differentiating into osteoblasts. mRNA expressions of osteoblast-specific transcription factors, OC, ALP, Runx2, and Wnt/β-catenin signaling pathway target genes, β-catenin, C-Myc, cyclin D1, were determined using RT-PCR method at different time after intervention with the optimal concentration of icarin. Expressions of Runx2, β-catenin, c-Myc, cyclin D1 regulated by the optimal concentration of icarin were detected using western blot assay at the protein level. RESULTS AND CONCLUSION:Cel viability and ALP activity decreased significantly in the cyclophosphamide group compared with the control group, but there was no significant difference in cel viability between icarin group and cyclophosphamide group. Icarin at 100 μmol/L showed the best protective effect against cyclophosphamide-induced obstacle of osteogenic differentiation of bone marrow mesenhymal stem cels. Compared with the control group, cyclophosphamide chemotherapy reduced the expressions of ALP, OC, Runx2 at mRNA level and Runx2 at protein level, weakened the expressions ofβ-catenin, cyclin D1 at mRNA level and active β-catenin, Cyclin D1, c-myc at protein level, and increased the expression of DKK1. Compared with the cyclophosphamide group, 100 μmol/L icarin increased the expression of osteoblast-specific transcription factors and Wnt/β-catenin signaling pathway genes at mRNA and protein levels, and reduced the expression of DKK1 protein. These results show that cyclophosphamide can lead to osteogenic differentiation disorder of mouse bone marrow mesenchymal stem cels, and in contrast, icarin shows a protective effect and its optimal intervention concentration is 100 μmol/L. Additionaly, the protective roleof icarin is probably related to activation of Wnt/β-catenin signal pathway.

OBJECTIVETo investigate the resistant effect of houttuyfonate sodium (SH) combined with imipenem (IMP) against Pseudomonas aeruginosa (Pa) biofilms.

METHODThe two-fold dilution method was used to examine the minimum inhibitory concentration (MIC) of the tested drug. The crystal violet staining was applied to detect the effect of the combination of 1/2MIC, 1MIC, 2MIC of SH, single IMP, 1/2MIC of SH and IMP of various concentrations on the clearance rate of adherent bacteria, growth of biofilms and alginate production. Fluorescein diacetate (FDA)-propidium iodide (PI) doubling staining assay was employed to observe the bacterial viability and morphological changes after membrane dispersion of each drug group.

RESULTSodium houttuyfonate could enhance the effect of IMP against pseudomonas aeruginosa biofilms. Particularly, the combination group with the concentration of 2MIC showed the highest effect, with P < 0.001 compared with the negative control group. The above results were proved by the bacterial viability and biofilm morphology under fluorescence microscope.

CONCLUSIONAfter being combined with imipenem, sodium houttuyfonate shows a higher effect against biofilms. It is expected that the combination of the two drugs could improve the clinical efficacy of associated infections.
