RESUMO
Objective To analyze the clinical effect of L-thyroxine combined with selenium yeast in patients with lymphocytic thyroiditis.Methods The clinical data of 96 patients with lymphocytic thyroiditis from March 2015 to September 2016 was analyzed retrospectively.The cases were divided into study group(48 cases)and control group(48 cases)according to double-blind method.The control group were treated with levothyroxine and the study group were treated with levothyroxine combined with selenium yeast.Free tetraiodothyronine(FT4),free triiodothyronine(FT3),thyrotropin(TSH),thyroglobulin antibody(TGAb),serum thyroid peroxidase antibody(TGAb)and serum thyroid peroxidase(TPOAb),the level of peripheral blood T cell subsets and the total effective rate between the two groups were compared.Results After treatment,the levels of FT4,FT3,TSH,TGAb and TPOAb in the two groups were significantly better than those before treatment(P<0.05).FT4,FT3,TSH,TGAb,TPOAb levels in the study group were significantly better than that in the control group(P<0.05).Compared with the control group,the T lymphocyte subsets of the study group after treatment were significantly better(P<0.05).Compared with the control group,the total effective rate of the study group was significantly higher(P<0.05).Conclusion The effect of L-thyroxine combined with selenium yeast in the treatment of lymphocytic thyroiditis patients is very significant.The treatment method is worthy of promotion in the clinical treatment.
RESUMO
Objective To explore the observation and nursing of traumatic mediastinal hematoma.Methods The clinical data in 44 cases of mediastinal hematoma treated in our department from July 2006 to May 2016 were analyzed retrospectively.Results Forty cases were cured,4 cases(9％) died,the mortality rate was 9％,in which 1 case died from postoperative consumptive coagulopathy,1 case died from acute coronary syndrome and 2 cases died from traumatic hemorrhagic shock.Conclusion Timely diagnosis and treatment of intrathoracic cardiac and vascular injury are the key to save the lives of patients;the nursing focuses include observing the hematoma progress,adopting the comprehensive treatment measures such as controlled hypotension,limited fluid resuscitation and correctly selecting infusion approach for preventing hematoma enlargement and rupture.
RESUMO
Objective:To evaluate the cytotoxicity of colorized zirconia ceramics.Methods:Zirconia ceramic 3Y-TZP blocks were colorized by NH4 VO3 ,FeCl3 ,Co(NO3 )3 ,Ni(NO3 )3 and MoCl3 respectively.The cytotoxicity of colorized zirconia to L-929 cells was examined by immersion method and MTT assay.Results:During 3 days culture,L929 cells in all groups showed similar prolifera-tion and normal morphology.The toxicity gradation of all groups was 0 -I.Conclusion:Zirconia ceramics colorized with the 5 kinds of colorants has no cytotoxicity.
