ABSTRACT
Objective:To compare serum level of β thromboglobulin in patients with coronary heart disease (CHD) complicated different complications.Methods:According to their complications,a total of 398 patients with unsta- ble angina pectoris (UAP)were divided into pure UAP group (UAP control group,n=82),hypertension group (n=89),diabetes mellitus (DM)group (n=133)and brain infarction group (n=94).Serum level of β thromboglobu- lin were measured and compared among four groups 6h after onset and before discharge.Incidence of myocardial in- farction within six months were followed up in four groups.Results:On 6h after onset,the serum level of β throm- boglobulin of brain infarction group,DM group,hypertension group,UAP control group was (61.13±3.32)ng/ml,(59.77±3.15)ng/ml,(52.12±3.27)ng/m, (48.55±3.14)ng/ml respectively,in which the level of brain infarction group was the highest,the difference between any two groups were significant (P0.05.Conclusion:β-thromboglobulin level during UAP onset is significant higher than that of remission period,and it rises most significantly in brain infarction group,and in this group the percentage of myocardial infarction occurred within six months is highest
ABSTRACT
Objective To study the clinical value of the combination detection of serum tumor markers alpha fetal protein hetero-geneity-L3(AFP-L3) ,Golgi protein 73(GP73) and phosphatidylinositol proteoglycan-3(GPC-3) in the diagnosis of primary hepatic cancer .Methods The serum AFP-L3 ,GP73 and GPC-3 levels were measured in 34 patients with primary hepatic cancer (PHC) ,20 patients with liver cirrhosis ,20 patients with chronic hepatitis B ,37 patients with other tumors by the enzyme linked immunosor-bent assay(ELISA) .Meanwhile ,20 individuals with healthy physical examination were selected as the control group .The expression situation of various indexes were compared and analyzed .Results The expression levels of AFP-L3 ,GP73 and GPC-3 in the PHC group were significantly higher than those in the control group and the other tumors groups ,difference was statistically significant (P<0 .05) .The areas under the receiver operating characteristic (ROC) curve of PHC in the single item detection of 3 markers were 0 .909 ,0 .832 and 0 .817 respectively .The areas of the ROC curve in the combination examinations of two items were 0 .935 , 0 .945 and 0 .912 respectively .The area of the ROC curve in the 3-item combined detection of PHC could be up to 0 .960 .Conclusion The combined detection of AFP-L3 ,GP73 and GPC-3 can increase the detective rate of PHC and has important clinical significance to early diagnosis of PHC .
ABSTRACT
Objective To investigate the clinical value of serum tumor marker alpha-fetoprotein heterogeneity 3 (AFP-L3),golgin 73 (GP73) and glypican 3 (GPC-3) in primary hepatic cancer by ROC curve.Methods The AFP-L3,GP73,GPC-3 levels in serum were detected in 34 patients of primary hepatic cancer by enzyme immunoassay.Meanwhile,same terms from 20 healthy volunteers were detected as normal group.The area under curve was made by SPSS 17.0.Each laboratory indicator levels were compared and analyzed.Results The AFP-L3,GP73,GPC-3 levels in primary hepatic cancer group were significantly higher than those in normal control [(1890.13±506.47) ng/L vs (623.40±317.89) ng/L,(219.53±136.33) ng/ml vs (56.40± 25.63) ng/ml,(14.28±7.15) μg/L vs (7.33±3.71) μg/L,P ＜ 0.01].The areas under the concentration-time curve of receiver operating characteristic of single tumor marker were 0.909,0.832,0.817,the areas of AFP-L3+ GP73,AFP-L3+GPC-3,GP73+GPC-3 were 0.935,0.945,0.912,the area of combined detection of primaryhepatic cancer was 0.96.Conclusion AFP-L3 combines with GP73 and GPC-3 can increase the positive rate in patients with primary hepatic cancer and has important clinical significance.
