ABSTRACT
Objective:To explore the proportions of Th17 cells in the peripheral blood and levels of IL-17,IL-23 in the serum of patients with Graves′disease ( GD ) and their clinical significance.Methods: We studied 29 patients with GD ( GD group ) , and reevaluated the GD group after therapy ( euthyroid GD group ).29 gender-and age-matched volunteers were selected as the normal control ( NC group).The proportions of Th17 cells were investigated by flow cytometry.The levels of IL-23,IL-17 in the serums were measured by ELISA.The levels of FT3,FT4,TSH were determined by ECLIA and the levels of TrAb were tested by RRA.Results:There were no significant difference among 3 study groups in sex and age match ( F=0.0075 , P>0.05;χ2=0.4213 , P>0.05 ).The proportions of Th17 cells and the levels of IL-17 , IL-23 were increased in the GD and euthyroid GD patients compared with the control group (respectively,P0.05).Correlation analysis revealed that the proportions of Th17 cells ,and the levels of IL-17,IL-23 were positively correlated with the levels of FT3,FT4,TrAb(r=0.588 2,0.337 2,0.371 0;0.549 6,0.287 5,0.342 7;0.361 0,0.420 8, 0.330 8;P<0.05 ,for all parameters ) ,and were negatively correlated with the levels of TSH ( r=-0.319 7 ,-0.472 8 ,-0.428 2;P<0.05,for all parameters).Conclusion:Th17 cells and their related cytokines IL-17,IL-23 are highly expressed in the serum of patients with GD.Th17 cells and their relative cytokines have certain relevance with 4 thyroid function parameters of the patients with GD , which can be used as biological markers for GD.
ABSTRACT
Objective:To explore the role of cytokines in the pathogenesis of Graves′disease(GD),by detecting the levels of IFN-γ,IL-6,IL-17 and TGF-β1 in GD patients who were newly diagnosed.Methods:A total of 23 patients with new onset GD and 23 gender-and age-matched healthy controls were examined.The levels of serum IFN-γ, IL-6, IL-17 and TGF-β1 were measured by ELISA,FT3,FT4 and TSH levels were determined by ECL IA;TrAb levels were tested by RRA.Results: There were no significant difference among GD and NC group in sex and age match ( t=0.334 8 ,P>0.05;χ2=0.410 7 ,P>0.05 ).The levels of serum IFN-γ,IL-6,IL-17 and TGF-β1 in the GD group were significantly higher than the control group ( P<0.05 ) .Correlation analysis revealed that IFN-γ,IL-6,IL-17 and TGF-β1 were positively correlated with FT3,FT4(r=0.324 6,0.453 2,0.431 0,0.463 8;0.413 2,0.441 5, 0.436 2,0.467 1;P<0.05 ).Conclusion: IFN-γ, IL-6, IL-17 and TGF-β1 are highly expressed in the newly diagnosed GD patients.They play an important role in the pathogenesis of GD ,and provide helpful evaluation indices of immune dysfunction to Graves disease.
ABSTRACT
Objective To discuss the construction of training model for cooperation between doctors and nurses and evaluate its teaching effect.Methods 101 nursing students and 80 clinical medicine students were involved in an overall training for the purpose of cooperation between doctors and nurses by using of Sim-man and then test and questionnaire were conducted to evaluate the effect of the training.Results Statistics showed that training for cooperation between doctors and nurses had improved in such factors as attitude to the cooperation,communication skills,team work,and adaptability (operant skill was note included).In addition,88％ of the subjects supported the views that this kind of training should be offered before their internship.Conclusions Training for cooperation between doctors and nurses by using Sim-man can cultivate awareness of cooperation between doctors and nurses and improve team work,and set a better foundation for good collaboration between doctors and nurses.
ABSTRACT
Objective To investigate the curriculum construction and evaluation of teaching effectiveness of simulation and comprehensive experiment for clinical nursing. Methods Based on the investigation of hospital, taking working progress and working task of nurses as orientation, we constructed the curriculum of simulation and comprehensive experiment for clinical nursing, and unfold in junior class (before clinical practice) for student nurses. The teaching effect was evaluated. Results Unfolding simulation and comprehensive experiment could effectively enhance the nursing students' ability to transform theoretical knowledge into clinical nursing practice, and was favorable to change the role of nurses and improve the satisfaction degree of clinical practice.Conclusions Unfolding simulation and comprehensive experiment for clinical nursing for student nurses before clinical practice is practicable and essential.
ABSTRACT
Objective To investigate the clinical application of ultrasound-guided percutaneous puncture aspiration and sclerotherapy of liver hydatid cysts.Methods Thirty-eight patients of hepatic hydatid cysts underwent ultrasound-guided percutaneous puncture aspiration and sclerotherapy;then 20%-25%septic hypertonic saline or 95%absolute alcohol were injected into the cysts (the volume was about 25%-50%of the aspirated fluid) ;and the fluid was reaspirated after 5-15 min.At last,5-10 ml sclerosing agent was injected again.Oral albendazole 30-50 mg/kg was administrated to all patients before and after the above procedures.Ultrasonic follow-up was performed at 3-month interval in the first year and once a year afterwards.Results The successful rate of once puncture was 100%.Aher 6 months,cysts volume reduced 50% in 16 patients,reduced 30% in 22 patients.One year later,34 patients were cured,3 were effectively treated and 1 was improved.All hydatid cysts volume gradually decreased and calcification occurred.The total cure rate was 100%. Conclusion Ultrasound-guided percutaneous puncture aspiration and sclerotherapy is a safe,effective and reliable treatment of liver hydatid cysts.
