Objective: To evaluate the mechanical properties of Rene95 alloy component made by laser engineered net shaping (LENS). Methods: The component was fabricated from Rene95 alloy powder by LENS, then the mechanical properties of the component, Rene95 alloy casting and dental Ni-Cr alloy casting were studied. Results: The tensile strength(MPa), yield strength(MPa), elongations(%) and the microhardness(Hv) of Rene 95 alloy component made by LENS were 1 354.27?63.44, 1 175.29?34.32, 16.53?5.85, and 464.33?10.95, those of Rene95 alloy casting 1 430.28?55.73, 1 145.52?29.78, 10.31?4.25 and 457.56? 11.38, those of dental Ni-Cr alloy casting 612.05?18.46, 426.06?12.70, 6.21?1.21 and 260.14? 6.08, respectively.Conclusion: The mechanical properties of Rene95 alloy component made by LENS were same as those of Rene95 alloy casting, better than dental Ni-Cr alloy casting.

objective: To study the effects of laser engineered net shaping(LENS) in the manufacture of dental prosthesis. Methods: An experiment LENS system, including a 5 kW continuous wave CO 2 laser, a four-axes numerical control working table and powder feeding system, was built up, by which, a rectangular LENS component was made from Rene95 alloy powder. The microstructure of the component was observed with scanning electron microscope and ESA analysis. Results: The size of the component was 120 mm?15 mm?15 mm , and the wall of the component was perpendicular to the base. The microstructure of the component was made up of fine columnar dendrite with the length of 10～20 ?m, 10 times less than that of the cast made from the same material. The main elements of the powder distributed homogeneously,the negative effect of segregation could be limited and the properties of the component could be improved.Conclusion: The microstructure of components made by LENS is much better than that of those made by casting from the same material.

Objective To detect the change and clinical significance of homocysteine (Hcy),hypersensitivity C response protein (hs-CRP) and hypersensitivity troponin I (hs-TnI) in patients with acute myocardial infarction (AMI).Methods Ninety-six cases of AMI were selected as the research group and 60 cases of coronary heart disease without AMI were enrolled in the control group.Blood samples were collected to measure the contents of serum Hcy,hs-CRP and hs-TnI.ROC curve was drawn and Logistic regression model was established to analyze the role of each index alone and combined detection in the diagnosis of AMI.Results The levels of Hcy,hs-CRP and hs-TnI in the research group were significantly higher than those in the control group (Hcy: (29.29±7.65) mol/L vs.(17.23±4.68) mol/L;hs-CRP: (15.47±5.01) mg/L vs.(9.21±3.15) mg/L;hs-TnI: (40.88±9.18) ng/mL vs.(7.34±2.12) ng/mL,t=2.78,8.66,34.36,P<0.05).The area under the ROC curve of Hcy,hs-CRP,hs-TnI were 0.802 (95%CI(0.729~0.874)),0.71(95%CI(0.62~0.792)),0.929 (95%CI(0.891~0.967)),respectively.The area under the combine detection curve was 0.971 (95%CI,0.950~0.992).The sensitivity of Hcy,hs-CRP and hs-TnI in the diagnosis of AMI were 79%,57%,87%,respectively,the specificity of the three groups were 72%,70%,90%,the sensitivity and specificity of combined detection were 96% and 88%.Conclusion Combined detection of Hcy,hs-CRP and hs-TnI plays a better role in the diagnosis of AMI than that of Hcy,hs-CRP,hs-TnI alone and has a high specificity and sensitivity in the diagnosis of AMI.

Objective To analyze the clinical characteristics of twin reversed arterial perfusion sequence (TRAP),and investigate its prenatal evaluation and clinical management.Methods Karyotype results and ultrasound data of 25 TRAP cases were retrospectively reviewed,including estimated weight and umbilical blood flow of acardiac twin,cardiac function and middle cerebral artery peak systolic velocity of pump twin.Various managements and the outcomes were analyzed.Results (1) Karyotype of amniotie fluid were tested in 16 pump twins.Mosaicism was found in 1 case (46,XX[36]/46,XY [14]).(2) According to the ultrasound evaluation,large acardia accounted for 87.0％ (20/23) cases.Abundant blood perfusion (inter-twin difference of umbilical resistance index ≤0.20) was indicated in 86.4％ (19/22) cases.Decompensation of cardiac function was suggested in 66.7％ (10/15) pump twins.Fetal anemia of pump twin indicated by middle cerebral artery peak systolic velocity＞1.5 multiples of the median was diagnosed in 75.0％ (12/16) cases.(3) The acardiac twin with abundant blood perfusion was more likely to be a large acardia than those without [94.7％(18/19) vs 1/3,Fisher exact test,P=0.04]; More pump twin with large acardia tended to have cardiac decompensation than non-large acardia pump twins [83.3 ％ (10/12) vs 0/3,Fisher exact test,P=0.02].(4) Eleven patients chose to terminate their pregnancies after being diagnosed.In 14 cases who continue the pregnancies,the survival rate of pump twin was 64.3％ (9/14).In 3 cases of non-large acardia without cardiac decompensation of pump twin,the patients selected conservative observation resulting in 2 term deliveries and 1 termination of pregnancy due to for exacerbation.Among 11 cases with large acardia,which the pump twins were complicated by cardiac decompensation or anemia,five cases selected conservative observation.One ended in spontaneous abortion; three exacerbated (one termination and two cesarean section before term with living births) ; one was stable until delivery.Another 6 cases received bipolar cord coagulation,and successful interruptions of acardiac blood flow were achieved in 5 cases among which 4 pump twins survived.Conclusions Prenatal diagnosis,cardiac function and fetal anemia of pump twin,together with the growth and blood supply of acardia are important indexes for prenatal evaluation of TRAP,on which our prompt management should be based.

Aim To investigate the effect of ginsenoside Rg1 on gut injury following intestinal ischemia reperfusion in rats and the possible mechanism.Methods By using rat model of intestinal I/R injury, 30 male SD rats were randomly divided into 3 groups(n =10 in each group):sham-operation group, I/R group(control group)and ginsenoside Rg1 group(treatment group).The contents of tumor necrosis factor α(TNF-α), interleukin-6(IL-6), malondialdehyde(MDA), the activity of superoxide dismutase(SOD)in intestinal mucosa were measured respectively.Chiu's count was used to assess the changes in intestinal pathological morphology.Results TNF-α, IL-6, MDA contents and the intestinal injury score in control group were significantly increased compared to those in sham-operation group, while SOD contents in control group were significantly decreased compared to sham-operation group.Inversely, TNF-α, IL-6, MDA contents and the intestinal injury score in treatment group were significantly decreased compared to those in control group, while SOD contents in treatment group were significantly increased compared to control group.Conclusion Pretreatment with ginsenoside Rg1 has protective effect on intestinal ischemia-reperfusion injury in rats, which may be attributed to decreased contents of TNF-α, IL-6, MDA and increased levels of SOD.

Objective To compare and analyze the phylogenetic tree and sequence variant characteristics of Klebsiella species between 16S rDNA and rpoB. Methods Eighteen isolates identified as genus Klebsiella (with 15 of K. Pneumoniae and 3 of K. Oxytoca) by automated biochemical tests were selected. DNA were extracted, 16S rDNA and rpoB genes were amplified and sequenced with Klebsiella 16S rDNA and rpoB primers. Together with already published 8 species of Klebsiella and 9 species of Enterobacteriaceae 16S rDNA and rpoB sequences from GenBank, totally 35 sequences of 16S rDNA and rpoB respectively, phylogenetic trees were constructed with MEGA 4.0 to the analysis of groups. DNAStar/MegAlign was used for comparison of variable regions of 16S rDNA and rpoB, with analysis of degree of divergent at the same time. Results As for all 35 sequences, both 16S rDNA and rpoB phylogenetic trees divided Klebsiella species into three groups, 15 of K. Pneumoniae in this study and 6 of K. Pneumoniae from GenBank (except for K. Oxytoca and K. Mobilis) cluster to group Ⅰ, K. Oxytoca and K. Mobilis were cluster to group Ⅱ and Ⅲ, respectively. In rpoB phylogenetic tree, no matter group Ⅰ and group Ⅱ, or subgroup within group Ⅰ, the bootstrap values in each node of rpoB phylogenetic tree is obviously higher than that of 16S rDNA. Moreover, as for cluster to K. Oxytoca, rpoB is better than 16S rDNA. Analysis nucleic acid sequences of Klebsiella species, with 41 variable regions and 4 most significant regions were found within the Klebsiella 16S rDNA, while rpoB with 63 variable regions, and 1 most significant region. The similarity of 16S rDNA and rpoB within Klebsiella were 95.9%-100% and 90.2%-100% respectively. Further analysis divergent degree of 16S rDNA and rpoB within Klebsiella, the divergent value of rpoB (0-10.6) is higher than that of the 16S rDNA(0-4.0). Conclusion As for molecular classification and identification within KlebsieUa species, rpoB has more advantages than 16S rDNA.

Objective:To evaluate the changes of quality of life in patients with axial spondyloarthritis (ax-SpA) after treatment with non-steroidal anti-inflammatory drugs (NSAIDs) by the 36-item Short Form Health Survey (SF-36).Methods: 120 patients diagnosed with ax-SpA were collected in the first Affiliated Hospital of Zhengzhou University from October 2014 to September 2015.They all agreed to be treated with the special drugs and assessed by special scale.Then they all signed the agreement.In the 3 months,double-blind,parallel controlled trial patients were randomized to 200 mg twice daily (bid) imrecoxib,or 200 mg twice daily (bid) celecoxib.They were assessed for the changes of quality of life at enrollment and after three months of NSAIDs therapy by the SF-36 of Chinese edition.The correlation between quality of life and erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),Bath Ankylosing Spondylitis Disease Activity Index (BASDAI),Bath Ankylosing Spondylitis Functional Index (BASFI),Spondylo Arthritis Research Consortium of Canada (SPARCC) was analyzed.Results: A total of 116 ax-SpA patients completed the study and 4 patients were lost to follow-up.We used the SF-36 scale to assess the quality of life in patients with ax-SpA before and after 3 months,NSAIDs treatment.The treatment effects were not statistically significant difference between the two drugs (P>0.05).After all the patients were treated with NSAIDs for 3 months,there was statistically significant difference (P<0.05) of the physical functioning,role-physical,bodily pain,general health,social functioning,role-emotional;and there was no statistically significant difference (P>0.05) of vitality and mental health.The positively significant correlations had been identified between BASDAI and PF,RP,BP,GH,VT,SF,RE (P<0.05),while no significant correlation was found between BASDAI and MH (P>0.05).A positively significant correlation had been identified between BASFI and PF,RP,BP,GH,SF,RE,MH (P<0.05),while no significant correlation was found between BASFI and VT (P>0.05).The ESR was positively correlated with SF,RE (P<0.05);and CRP was positively correlated with SF,MH (P<0.05);and SPARCC was positively correlated with PF (P<0.05).BASDAI and BASFI were the important influence factors of PF (P<0.05);and BASDAI was the important influence factor of BP,GH,VT,RE(P<0.05);BASFI was the important influence factor of RP,SF,MH(P<0.05).Conclusion: Non-steroidal anti-inflammatory drugs can improve the quality of life of the ax-SpA patients.Imrecoxib and celecoxib have the equivalent curative effect.SF36 scale is suitable for the assessment of the quality of life in patients with ax-SpA.
