Objective To study the effect of heat treatment with sol-gel method on the surface of Ni-Cr alloy for PFM after Ti coating. Methods To establish the sol-gel method of Ti coating on the surface of Ni-Cr dental casting alloy for PFM(pre-treatment for the surface of Ni-Cr alloy,preparation of sol,coating,heat treatment) and to evaluate the color and fragmentation of 10 materials after heat treatment by ISO 10289. Results When kept at a higher condensation temperature and held for a longer time,the materials had less fragmentation.A higher agglutination temperature and a longer time made the materials look deep.When the condensation process was heat treated at(200 ℃) for 2 h and the agglutination process at 450 ℃ for 2 h,the thin film of Ti combined firmly with the surface of Ni-Cr alloy. Conclusion The procedure for heat treatment of Ti coating will affect the level of oxidation reaction on the surface of Ni-Cr alloy,and will change the level of combination between Ti and Ni-Cr alloy.

Objective To study the effect of Mutans Streptococcus(S.Mutans) on the corrosion resistance of Ni-Cr alloy. Methods S.Mutans were isolated in TSB,and then 10~(5)10~6 CFU/mL of bacterial population was reached.The self-corrosion electrical current density and the corrosion electrical current potential of Ni-Cr alloy were found from polarization curves under the condition with or without media plus S.Mutans.The surface of Ni-Cr alloy after bacterial corrosion was examined with X-ray photoelectron spectroscopy(XPS) to find out different element contents.(Results)From polarization curves,it could be found that the self-corrosion electrical current density and the corrosion electrical current potential of Ni-Cr alloy without S.Mutans were 53.5 ?A/cm~(2)and-62 mV,and those with S.Mutans were 75.7 ?A/cm~(2)and-220 mV.Examination of XPS showed that besides Ni and Cr,the element of chlorine(Cl),sulphur(S),calcium(Ca) could be found on the surface of Ni-Cr alloy after bacterial corrosion.(Conclusion Because of) the metabolism of S.Mutans,an oxide film could be destroyed and a biofilm be formed on the surface of Ni-Cr alloy.Bacterial corrosion could lower the corrosion resistance performance of Ni-Cr alloy.

Objective To explore the effect of atorvastatin on high-sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6) in unstable angina pectoris (UAP) patients after intervention.Methods Eighty cases with UAP who underwent percutaneous coronary intervention (PCI) were divided into group A and group B by random digits table method with 40 cases each after PCI.The patients in group A were given regular heart treatment and atorvastatin 20 mg treatment.The patients in group B were given regular heart treatment and atorvastatin 40 mg treatment.The serum hs-CRP and IL-6 was determined before treatment and 24 h,3 weeks after treatment and compared between two groups.Results There was no significant difference in the serum hs-CRP and IL-6 before treatment between group A and group B [(5.6 ± 1.2) mg/L vs.(5.6 ± 1.1) mg/L and (211.9 ± 21.2) ng/L vs.(209.6 ± 19.9) ng/L,P ＞ 0.05].The serum hs-CRP and IL-6 24 h after treatment in group A and group B were increased compared with that before treatment,and there was significant difference(P ＜ 0.05),but there was no significant difference between group A and group B[(8.1 ± 1.1) mg/L vs.(8.5 ± 1.2) mg/L and (311.1 ± 20.9) ng/L vs.(313.3 ± 18.5) ng/L,P＞ 0.05].The serum hs-CRP and IL-6 3 weeks after treatment in group A and group B were decreased compared with that before treatment,there were significant difference (P ＜ 0.05),and there were significant difference between group A and group B [(3.1 ± 1.1) mg/L vs.(1.9 ±0.8) mg/L and (163.3± 18.5) ng/L vs.(123.3± 19.5)ng/L,P ＜ 0.05].No obvious adverse reaction was observed in two groups after treatment and liver function was not seen obvious anomaly.Conclusions Atorvastatin treatment in UAP patients after PCI can significantly reduce the serum hs-CRP and IL-6,and the 40 mg treatment is better than the 20 mg treatment.It is worth of clinical application.

Objective To summarize the diagnosis and treatment of 33 cases of Leriche syndrome. Methods A retrospective review of the clinical data of 33 cases of Leriche syndrome was done. Results Claudication and impotence occurred in 79.9% and 70.4% of the cases. Color Doppler ultrasonography, especially combining with CTA or MRA, was helpful for the diagnosis. Aortic angiography or DSA was necessary for the determination of the clinical patterns and selecting the therapeutic methods. Surgical patterns selestion should be considering the patients' general status and conditions of the affected vessels. Surgical treatment was performed on 25 cases, including12 aortoiliac artery bypasses , 6 aortobifemoral artery bypasses , 4 axillo bifemoral artery bypasses, 2 embolectomies by Fogarty tube only and 1 aortal interposition with artificial vessel plus renal artery plasty. Aorta iliac artery bypasses get the best results with 1 year patency rate(100%) in all cases, and 5 year patency rate of 75.0%, which was significantly superior to those axillo bifemoral artery bypass grafts with 5 year patency rate of 37.5%. All the other 8 patients without operation died within 5 months. Conclusions Early diagnosis and comprehensive therapy should be adopted to improve the long term patency rates of grafts transplantation in Leriche syndrome.
