BACKGROUND: Although nickel and chromium are essential elements of human body, over high concentration of them will produce many adverse effects to human body, therefore biological safety of nichrome material for dental restoration deserves attention.OBJECTIVE: To observe the changes of nickel and chromium content at 6 months and 1 year after porcelain-fused-to-nichrome crown restoration, and compare to healthy controls to investigate the long-term safety of nichorme in oral cavity.DESIGN, TIME AND SETTING: A case-control observation was performed between January 2006 and December 2007 at the First Affiliated Hospital of Hebei North University, Zhangjiakou, Hebei Province, China.PARTICIPANTS: Sixty patients who visited Department of Stomatology, the First Affiliated Hospital of Hebei North University, between January and December 2006 were included in test group, including 28 male, 32 female, the mean age was 40 years. Each of them had 3 anterior maxillary teeth restored by porcelain-fused-to-nichrome crowns, without other metal fillings or protheses. Sixty healthy cases visited the hospital at the same time were used as control, including 30 male, 30 female, the mean ages was 39 years.METHODS: Fasting venous blood of participants in two groups was harvested sterilely at 6 months and 1 year after test group restoration, serum nickel and chromium content were determined using graphite furnace atomic absorption spectrometry.MAIN OUTCOME MEASURES: ① Serum nickel content changes in test and control group. ②Serum chromium content changes in test and control groupRESULTS: All cases were involved in result analysis. ① Serum nickel content changes in test and control group: At 6 months postrestoration, there was no significant difference in serum nickel content between test group and control group (P>0.05). At 1 year after restoration, serum nickel content of test group was significantly higher than that of control group (P<0.05). ② Serum chromium content changes in test and control group: There was no significant difference in chromium content between test and control group at 6 months and 1 year after test group restoration (P>0.05).CONCLUSION: Nickel and chromium released from porcelain-fused-to-nichrome crowns after restoration under oral environment, serum nickel content had an increasing tendency with the prolongation of restoration time, but in small quantity and within biosafety range, to identify whether the increasing tendency will increased continuously with the prolongation of restoration time needs long-term follow-up.

Objective A retrospective analysis was conducted to review the distribution and antibiotic resistance in the Staphy-lococcus aureus strains isolated from sputum and provide evidence for effective prevention and control of infections.Methods The 276 strains of S .aureus isolated during the period from January to September of 2009 were included in this analysis.The isolates were identified and tested for susceptibility using VITEK 2 Compact Automatic Culture and Identification System. Results The prevalence of methicillin-resistant S .aureus (MRSA)was 79.0% (218/276).The S .aureus strains were mainly isolated from Department of Neurology (27.5%,76/276),ICU (25.4%,70/276),Neurosurgery (18.1 %,50/276),and Re-spiratory Medicine (9.1 %,25/276).Vancomycin,teicoplanin and quinupristin-dalfopristin were the most active agents against these S .aureus .The resistant strains were less than 0.5%.MRSA showed lower resistance rate to trimethoprim-sulfamethox-azole than MSSA.MRSA strains were more resistant than MSSA to most other antibacterial agents.Conclusions The MRSA i-solates from sputum are highly prevalent and resistant to antibiotics.Antimicrobial agents should be selected appropriately ac-cording to the results of susceptibility testing.

Objective: To evaluate the safety of acute normovolemic hemodilution (HD)during induced hypotension (IH). Method: 12 healthy mongrel dogs, were anesthetized and paralysed with sodium pentobarbital and pipecuronium. Ventilation was controlled. Hypotension was induced with nicardipine to lower the MAP by 30% after Hct was reduced to 0.35,0.30,0.25,0.20,0.15 or 0.10 respectively. Blood gases,lactate level(LAC)and hemedynamic variables were measured 15 minutes after HD and 20 minutes after IH. Result: Compared with HD alone, when combined with IH, CI.DO_2 and LAC increased significantly (P

Helicobacter pylori (Hp) is a kind of Gram negative pathogen which serious threats human health. With the widespread use of antibiotics, the drug resistance of Hp is more and more serious, which has become the leading cause of failure in the treatment of Hp related diseases. Therefore, effective ways to find the intervention of drug resistance of Hp have become a practical problem to be solved in clinic. TCM and Western medicine in the treatment of drug resistant of Hp play their respective advantages. This article analyzed the research status quo and intervention effects of TCM and Western medicine for drug resistance of Hp, with a purpose to provide a new path for clinical treatment of Hp related diseases.

ObjectiveTo elucidate the association between RANKL rs7984870 C ＞G polymorphism and the susceptibility to rheumatoid arthritis in a Chinese Han population.MethodsGenotypes were determined by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) method in 214 rheumatoid arthritis cases and 478 controls.ResultsThe RANKL rs7984870 C＞G genotype frequencies were 27.3% ( CC),51.2% ( CG),21.5% (GG) in the rheumatoid arthritis group and 25.3% (CC),49.1% (CG),25.7% (GG) in the control group respectively; Logistic regression analyses revealed that the risk associated with RANKL rs7984870 C＞G variant genotype was 0.78 (95% CI =0.49-1.24) for RANKL rs7984870 GG compared with its wild-type homozygote.ConclusionRANKL rs7984870 polymorphism may not serve as a risk factor of rheumatoid arthritis susceptibility.Further functional studies are warranted to verify our findings.

Objective We compared the new teaching curriculum of evidence-based medicine (EBM) with the traditional one to explore a more effective one of EBM and provide reference for the popularization of EBM in Xinjiang.Methods From the fourteen regions in Xinjiang,we selected randomly four regions,and the trainees of the four regions were allocated randomly to the experimental group (169) and the control group (167).The new teaching curriculum was used in the experimental group and the raditional one in the control group.After training,we investigated all the trainees with questionnaires and compared the differences of the two groups.Results Compared with the control group,trainees of the experimental group were significantly enhanced in the abilities of cognition (χ2 =6.870,P=0.009),literature retrieval (χ2 =22.670,P=0.000),communication (χ2 =6.288,P =0.012)and scientific research (χ2=4.667,P = 0.031).However,the difference in the ability of diagnosis and treatment (χ2 =0.663,P=0.426) was not significant.On the other hand,the total examinational scores and the scores for the chapters of general introduction,etiological factor,diagnosis and system review of the experimental group were significantly higher than those of the control group,but there was not significant difference between the two groups in terms of the scores for the chapters of treatment and prognosis.Conclusion The new teaching curriculum of EBM is beneficial in developing the abilities of cognition,literature retrieval,communication,scientific research and apprehension of EBM theory and is more applicable for the popularization of EBM in Xinjiang.

Purpose:To study the clinical significance and hematologic features of CD56 + Acute Myeloid Leukemia(AML). Methods:The expression of differentiation antigens on the acute myeloid leukemia cells were detected by flow cytometry(FCM);the Epstein-Barr Virus(EBV) mRNA in CD56 + AML leukemic cells by Rt-PCR assay;the ultrastructure of the CD56 + AML leukemia cells were showed by electron microscope and immuno-electron-microscope. The hematologic features and clinical characteristics at the first visit retrospectively analysed as well as the effect of chemotherapy.Results:CD56 expression rate in AML was 30.62%(79/258).EBV-mRNA were negative in all CD56 + AML cells detected.The ultrastructural characteristics showed 1-2 masses floccose objects in nucleus of CD56 + AML leukemic cells,CD56 expression had no correlation with age,sex,WBC,Hb,BPC,Leukemic cell count in BM,CR rate and CR duration(P value is 0.128,0.877,0.181,0.866,0.629,0.407,0.998 and 0.096,respectively),but there was correlation with higher extramedullary involvement(77.78% v 61.11%,P=0.019)?higher expression of CD34 (66.67% v 46.48%,P=0.03),higher expression of P170(51.79% v 34.94%,P=0.048) and shorter survival(Median,11.5 months v 18 months,P=0.0478). Conclusions:AML was a specific subtype of AML,with a poor prognosis.It may be useful to have more detailed classification with appropriate therapy for this subtype.

Objective To investigate the factor that affecting the prevalence of osteoarthritis in rural areas of Shanxi, China. Methods All the residents above 16-year-old from the villages chosen by multi-stage stratified cluster sampling in Yangcheng County and Pianguan County in Shanxi Province were investigated by COPCORD procedure of WHO. All respondents signed the informed consent forms. Chi-square test and multivariable logistic regression analysis were used for the risk factor analysis. Results Seven thousand one hundred and twenty-six permanent residents in the two counties were investigated, of which 1734 cases of patients with osteoarthritis were identified. Take with or without osteoarthritis as response variables, statistically significant variables in the univariate analysis were substituted into the logistic regression model. Forward method was used for the variable selection. The inclusion criteria set as 0.10. The results showed that, age, room heating and ventilation, marital status, occupation, education, engaged in coal mine work, accompanied cardiovascular disease were the risk factors for osteoarthritis disease. Conclusion There were many factors that affect the prevalence of osteoarthritis in Shanxi rural communities, in which lifestyle may play an important role. Early intervention on risk factors may have a significant effect on reducing the prevalence.
