Objective:To investigate the effect of porcelain bake cycles on oxide layer form ed on cobalt-chromium alloy surface.Methods:Fixed spot analysis of EPMA methods was adopted to measure the oxygen at o mic percentage inward from the edge of cross-section interface of alloy pieces. The adherent state of oxide layer on the surface of substrate alloy was observed .Results:The oxide layer on the surface of alloy had stable thickness and contain ed more and more oxide as porcelain firing times increased.In some area,oxide la yer fractured from the substrate metal.Conclusion:Cobalt-chromium alloy frame should be abrased and polished thoroughl y after porcelain bake cycles.

The arbuscular mycorrhizal(AM)symbiosis is a mutualistic endosymbiosis formed by plant roots and AM fungi.The AM symbiosis is manifested in bidirectional nutrient exchange: AM fungi obtain carbon from their plant host while assisting the plant with the acquisition of mineral nutritions(in particular phosphate)from the soil.AM symbiosis facilitate phosphate uptake is the central reason of plant growth and development.Phosphate transport into the root is mediated by phosphate transporters,and phosphate transporters play a role in the acquisition of phosphate released by the fungus in the AM symbiosis.The molecular biology of arbuscular mycorrhizal symbiotic phosphate transporters in plants was summarized.AM phosphate transporter belong to Pht1 family,is not only essential for the acquisition of phosphate,also critical to AM symbiosis.Study of phosphate transport roles and their gene regulation will further our knowledge of the interaction between the two symbiotic partners,and so as to provide innovative approach to improving phosphate efficiency and agricultural yield.

The incretion secretion metrical technique is the important embranchment in clinical diagnosis presently,in which the magnetic separate enzyme immunoassay is the main technique.This paper introduces the principle and design of Chinese enzyme immunoassay instrument,and emphatically discusses the design of nonlinear data processing model.

Objective:To explore the dynamic changes of nitric oxide and prostaglandine levels in gastric mucosa and plasma of rats with seawater immersion injury after open abdominal trauma Methods:Thirty-two Sprage-Dawley rats were randomly assigned into four groups:normal control group,celiac seawater-immersing trauma stress 1,2,3h groups.The contents of nitric oxide and prostaglandine in gastric mucosa and plasma of rats were detected by chemochromometric and immunoassay methods respectively.Results:Compared with normal control group,both the nitric oxide and prostaglandine levels in gastric mucosa and plasma of rats under celiac seawater-immersing trauma were progressively increased (P

[Objective] To observe the therapeutic effect of wind - dispelling, blood - activating and stasis - removing Chinese herbs combined with autoepidermic grafting for vitiligo. [Methods] Forty cases of vitiligo were randomized into two groups: 28 cases in Group A were treated with Chinese herbs combined with autoepidermic grafting (235 grafts in all) and 12 in Group B with autoepidermic grafting (118 grafts in all) alone. [Results] In Group A, 1 case was cured, 13 were markedly effective, 10 effective and 4 ineffective and 0, 3, 3, and 6 in Group B respectively. The therapeutic effect in Group A was superior to that in Group B (P = 0.034). [Conclusion] Chinese herbs combined with autoepidermic grafting has a better effect than autoepidermic grafting alone for vitiligo.

OBJECTIVE:To establish a method for the determination of Oleanolic acid and Ursolic acid isomers in Hedyotis corymbosa.METHODS: Capillary zone electrophoresis with high frequency conductivity detection was adopted.The separation of sample was performed on an uncoated fused silica capillary(55 cm?75 ?m ID) at an effective length of 50 cm.1.2 mmol?L-1 Triethylamine(TEA)-HCl(pH10.0) buffer containing 0.24 mmol?L-1 ?-cyclodextrin was selected for the running buffer solution.The voltage applied was 12.5 kV and the sample was injected by gravity for 10 s at a height of 20 cm.Brufen was used as internal standard.RESULTS: The linear ranges for Oleanolic acid and Ursolic acid were 3.9～39.0 ?g?mL-1(r=0.999 1) and 20.0～140.0 ?g?mL-1(r=0.999 0),respectively,and their average recovery rates were 96.5% and 96.0% respectively and RSD were 1.98% and 1.09%,respectively(n=6).CONCLUSION:It was proved that the method was simple,accurate,rapid and reproducible,and applicable for the quality control of Hedyotis corymbosa.

Objective] To observe the diagnosis value of noninvasive diagnosis model S index used to evaluate the fibrosis degree of slight chronic hepatitis B(CHB). [Method] Trace back and investigate the routine serological indicators GGT, PLT, ALB and liver aspiration biopsy results of 63 cases of CHB;use noninvasive diagnosis formula to calculate:S index=1000×GGT/(PLT×ALB2),use ROC curve to analyze and evaluate the clinical diagnosis value of S index. [Result] S index is in positive relation with liver fibrosis degree. S index can forecast the fibrosis having or not with best truncation point 0.04h, the sensitivity 87.0%, specificity 47.5%and area under the curve(AUC) 0.690,close to 0. 7; in forecasting obvious fibrosis, with best truncation point 0.04h, sensitivity 100%,specificity 36.8%,AUC 0.664. [Conclusion] S index used for forecasting slight CHB having or not fibrosis has high value of diagnosis, but it has low correctness for diagnosing having or not obvious liver fibrosis.

Recent developments on separation and analysis of bacterial cells by capillary electrophoresis are reviewed. Based on bacterial surface characterization, capillary electrophoresis technique can be utilized for rapidly identify and quantify intact bacteria and microbes at a certain phase. The microbe-molecule interactions can also be described. The separation of microbes that can not be cultured in lab appears to be possible by this method. It makes profound effects on separation science and microbiology to establish capillary electrophoresis procedure for the separation and analysis of bacterial cells.
