RESUMO
Objective To investigate the diagnostic value of the soluble transferrin receptor (sTfR)in non-adult iron deficiency anemia (IDA)and its differential diagnostic value between IDA and anemia of chronic disease(ACD).Methods 26 cases in the IDA group involved 12 males and 14 females,aged 1 month to 15.5 years;33 cases in the ACD group involved 17 males and 16 females, aged 2 months to 14.0 years;30 cases in the normal control group involved 15 males and 15 females,aged 1 month to 15.5 years. Serum sTfR and ferritin (SF)were detected by the immunonehelomitery,serum iron (SI)was detected by Ferrous Oxazine colori-metric method.Results The gender and age had no statistically significant difference among 3 groups;the SI mean value in the ACD group located between the IDA group′s and the normal control group′s;the SF mean value of the IDA group was significantly lower than that of ACD group (P <0.001)and that of control group (P <0.001),while the sTfR mean value of IDA group was significantly higher than that of the ACD group (P <0.001)and that of the normal control group (P <0.001).The best cutoff of sTfR for the differential diagnosis between IDA and ACD was 3.56 mg/L,its sensitivity,specificity,negative predictive value,posi-tive predictive value and accuracy were 95.12%,93.92%,94.11%,97.53% and 95.50% respectively.Conclusion sTfR has higher sensitivity and specificity for IDA and is conducive to diagnose IDA and differentially diagnose ACD.
RESUMO
Objective: To learn law students' understanding of and demand for knowledge of forensic medicine,especially their attitude for autopsy and adjust the teaching reform in forensic medicine.Methods: Investigation was made by anonymous questionnaire in law undergraduates of 1999 and 2000 grades in Law College of Shantou University.Results: Almost all the students considered forensic medicine essential for themselves.The antitheist rate of the students in non-Chaoshan area(75.2%) was higher than that of the students in Chaoshan area(54.2%).57.4% of the students didn't want to join autopsy because of dread without obvious causes.93.3% of them thought that the autopsy should be taken by the legal medical experts.Conclusion: The law students prevalently enjoy the courses of forensic medicine,and they are more interested in the knowledge of forensic pathology.
RESUMO
The views of the students,from 2000 to 2003 grades in Medical College of Shantou University and other universities,on medical education and great doctors were investigated anonymously,and the related questions were discussed to provide the references for teaching reforms.
