ABSTRACT
Objective To explore the clinical significance of early biomarkers in neonatal asphyxia diagnosis with myocardial damage by detection of ischemia modified albumin in neonatal serum(IMA) and glycogen phosphorylase isoenzyme BB(GPBB) for screening sensitive markers with direct myocardial injury.Methods 166 neonates were selected in our hospital as the research object,in which 136 cases with myocardial injury dividend into the experimental group and 30 cases into the control group.The experimental group were divided into mild group and severe group according to the degree of asphyxia.All the children were tested for GPBB and IMA 1 h after admission.Results The levels of GPBB in neonatal asphyxia myocardial injury group and severe asphyxia group were significantly higher than those in the control group,the difference was statistically significant(P<0.05).The sensitivity of GPBB in diagnosis of asphyxia was higher than that of IMA,the difference was statistically significant(P<0.05).Conclusion The degree of asphyxia is closely related to serum IMA,GPBB level in neonatal asphyxia complicated with myocardial injury.The sensitivity and specificity of GPBB in diagnosis asphyxia is better than IMA in children complicated with myocardial damage.
ABSTRACT
Objective To explore the significance of combined detection of tumor markers cancer embryo antigen (CEA) ,alpha fetoprotein (AFP ) ,carbohydrate antigen 19-9 (CA19-9 ) and carbohydrate antigen 72-4 (CA72-4 ) in digestive tract tumors . Methods The electrochemical luminescence method was adopted to detected the CEA ,AFP ,CA19-9 and CA72-4 levels in 106 cases of digestive tract malignant tumor confirmed by pathological examination (malignant tumor group) ,110 cases of digestive tract be-nign diseases (benign disease group) and 60 persons undergoing the healthy physical examination (control group) in our hospital from January to December 2015 .The differences were compared among various groups and the positive detection rates of 4 markers in the patients with digestive tract tumors were compared .Results The serum levels of CEA ,AFP ,CA19-9 and CA72-4 levels in the malignant tumor group were significantly higher than those in the benign disease group and control group(P0 .05) .In the single indicator detection of ser-um CEA ,AFP ,CA19-9 and CA72-4 ,AFP had the highest detection rate in hepatocellular carcinoma (HCC) ,which was 74 .19% ;the positive detection rate of CA 72-4 in gastric cancer was highest ,which was 60 .71% ;the positive detection rate of CA 19-9 in pan-creatic cancer was highest ,which was 75 .00% ;the positive detection rate of CEA was not high without specificity in various tumor diseases .The positive detection rate of 4-item combined detection was significantly higher than that of single item detection (P<0 .05) .Conclusion The detection of tumor markers CEA ,AFP ,CA19-9 and CA72-4 is conducive to the identification of tumor types ,meanwhile they can improve the detection rate of gastrointestinal cancer and conduces to early diagnosis and early treatment for the patients .
