Objective:To evaluate the effects of platform switching and platform matching system on the marginal bone resorption a-round implant.Methods:Randomized controlled trials (RCTs)that compared marginal bone loss around platform-switched implants with platform matched prostheses were selected from PubMed,EMbase,CBM,CNKI and other electronic databases supplemented by hand search and retrospective collection of literature published or unpublished between 1 991 -201 4.The literature based on inclusion and exclusion criteria was screened by 2 revieweres independently,the quality of the included studies was evaluated,the data were extracted using RevMan 5.2 software for Meta-analysis.Results:1 4 studies with 1 331 implants were included.Meta-analysis showed that peri-implant bone resorption in the platform switching group was significantly less than that in the platform matching group[MD =-0.51 ,95% CI:(-0.72 -0.30),P <0.01 ].Subgroup analysis showed that the implant-abutment diameter difference >0.45 mm (unilateral)was more favorable to implant marginal bone preservation.Conclusion:The present data suggest that platform-switched technology is more conducive to implant bone preservation than platform-matched method.

Objective:To evaluate the effect of different polishing instruments on the microstructure of composite resin.Methods:Specimens of 5 kinds of resins were randomly divided into three groups and were polished with Astropol(group A),Sof-Lex(group B) and Super-snap(group C)respectively(n=3 for each resin).Specimens of natural enamel surface were used as the controls(group D).The surface roughness(Ra)and microstructure of the specimens were evaluated by an atomic force microscope(AFM).Results:Ra value in group A was lower than that in group B(P=0.015);Z350 XT resin obtained the lowest Ra value among the 5 kinds of resin specimens(P<0.05).All of the resin specimens had similar average Ra after polishing procedure(P>0.05).Conclusion:Astropol polishing instrument is better than Sof-Lex;Z350 XT has better polish performance.The three polishing instruments are ef-fective in polishing the 5 composite resins.

2 cm) who were treated with endoscopic polypectomy in 2 different means,respectively.Methods The clinic data of 68 children with giant colonic polyps were review analyzed.Thirty-five cases were received endoscopic clips ligation and the other 33 cases were received endoscopic snare resection.Results All the 35 cases out of endoscopic clip ligtion group were sucessfully cured.There were only 3 cases showedl a little bleeding in this group.In the endoscopic snare resection group,there were 10 cases showed bleeding,8 cases showed polypectomy syndrome,1 case transferred into(operation).Conclusions The complication incidence in endoscopic clips ligation group is lower than that in endoscopic snare resection group.The endoscopic clipping brings about an effective and safe way to treat giant colonic polyps in children.

?-arbutin is biosynthesized by whole cell method with Xanthomona maltophilia BT-112.The conditions for cell biosynthesized ?-arbutin are investigated as follows:temperature,25℃;concentration of hydroquinone,30mmol/L;mol ratio of sucrose and hydroquinone,20∶1;time course of ?-arbutin biosynthesis,45 hours;rotational speed,160r/min;concentration of Xanthomona maltophilia BT-112,85g/L;concentration of K-2HPO-4-KH-2PO-4 buffer solution,25mmol/L;pH of K-2HPO-4-KH-2PO-4 buffer solution,8.0.Under the above optimal conditions,the maximum of molar conversion yield based on the amount of hydroquinone supplied reaches 86.7%.

Objective: To observe the changes of liver metabolism in mice exposed to artificial light at night. Methods: Healthy male C57BL/6J mice were randomly divided into the light at night group and the control group, with 8 mice in each group. The daily light/dark cycle was 12/12 hours in the control group, and 24/0 hours in the light at night group for 10 consecutive days. The hepatic metabolite profiles of the two groups of mice were detected by high performance liquid chromatography tandem mass spectrometry. The modelling was assessed by combining principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis ( OPLS-DA ) , The changes of metabolites in the two groups were compared through KEGG database. Results: Compared with the control group, 9 different metabolites were detected in the light at night group, among which the down-regulated metabolites were glycine-betaine, glutathione, tyrosine, betaine, lysine, hypoxanthine, histidine and methionine, and the up-regulated ones were mannose-6-phosphate. The weight analysis of the metabolic pathways showed that the major influences on liver of light at night group were phenylalanine-tyrosine-tryptophan metabolism, tyrosine metabolism, fructose and mannose metabolism, cysteine and methionine metabolism and histidine metabolism. Conclusion The metabolism of various amino acids and sugars in light at night mice is disturbed,and the key differential metabolites are tyrosine, methionine, histidine and mannose-6-phosphate.

Armillariella tabescens EJLY2098 was capable of secreting p-mannanase by konjac inducement. A 34 orthogonal design was applied to determine the optimum medium of inducing mannanase by Armillariella tabescens EJLY2098. The results suggested that Armillariella tabescens EJLY2098 secreted the high-activity enzyme in the optimum medium, which was composed of 2% konjac, 1% peptone, 25% potato juice,0.3% KH2PO4,15% MgSO4?7H2O, 0.01% VitB1. Purified by DEAE-anion exchange chromatography, two eluting peaks (P1 and P2) with the p-mannanase activity were obtained, and one of them (named?-mannanase P2) was a single band by the SDS-PAGE, and the molecular weight of?-mannanase P2 was 78. 9kDa. The isoelectric point of?-mannanase P2 was estimated to be 4.0-4. 1. The optimum activity for the enzyme was found at 60℃and pH4. 0 - 6. 0, and the enzyme was stable between pH4. 5 - 6. 0. The activity of?-mannanase P2 were enhanced by Na+ and Ba2+ . This?-mannanase can be used in feed industy. a new fungi secreting?-mannanase was obtained, providing an important base for cloning mannanase gene and constructing recombin microbe expressing?-mannanase .
