ABSTRACT
Objective To evaluate the levels of serum TAM and Cyfra21-1 in diagnosis and chemotherapeutic efficacy assess-ment of patients with esophageal cancer.Methods The serum TAM and Cyfra21-1 levels were measured in 92 patients with initially diagnosed esophageal cancer or postoperative recurrence of esophageal cancer from September 2012 to September 2013 and 50 cases of healthy people in the same periods as control.The sensitivity and specificity of TAM and Cyfra21-1 were analyzed.Moreover,60 patients with high TAM and Cyfra21-1 levels before chemotherapy from September 2012 to A-pril 2014 were detected TAM and Cyfra21-1 levels after two cycles of chemotherapy.Relation between changes of TAM or Cyfra21-1 and chemotherapeutic efficacy were investigated.Results The diagnostic sensitivity of TAM for esophageal canc-er was 71.7%,which was higher than that of Cyfra21-1 (51.1%,P = 0.004).The diagnostic specificity of TAM and Cy-fra21-1 for esophageal cancer was 94.0% and 92.0% respectively.There were no significantly different between TAM and Cyfra21-1 (P =0.695).Of patients undergoing chemotherapy,the overall response was 25 cases,progress was 11 cases. There was no statistically significant difference in the coincidence rate of TAM and Cyfra21-1 (77.8% vs 75.0%,P =0.781).Conclusion Detection of serum TAM and CYFRA21-1 was valuable in the diagnosis and assessment of the thera-peutic efficacy of chemotherapy in patients with esophageal carcinoma.TAM was better than Cyfra21-1 in the diagnosis of e-sophageal carcinoma.
ABSTRACT
Objective To investigate the risk factors of intrauterine hepatitis B virus (HBV)infection and its preventive measures.Methods 254 cases of pregnant women with positive HBsAg and their neonatuses from Shaanxi People’s Hospi-tal were selected as the research object.The serum of pregnant women were tested HBV markers and HBV-DNA,their neo-natal umbilical cord blood were only detected HBV markers.Results In 254 samples,the positive rates of HBsAg and HBeAg within their neonatal umbilical cord blood were 5.12% and 13.78% respectively;the positive rate of HBV infection in neonatal umbilical cord blood among maternal HBeAg-positive group was 53.33%,far higher than 3.61% in HBeAg-neg-ative group (χ2 =99.44,P <0.001);the positive rates of HBsAg and HBeAg in neonatal umbilical cord blood were elevated along with the increase of maternal HBV-DNA copy (Hc= 13.50,66.70;P < 0.001).The positive rate of HBV-DNA in pregnant women with HBeAg-positive group was 100%,far more than 19.59% in HBeAg-negative group (P <0.001).Con-clusion Both maternal positive HBeAg and HBV-DNA are risk factors for neonatal intrauterine HBV infection.Prenatal HBeAg screening is predominant,especially in some hospitals without real-time quantitative assay.An effective measure to reduce intrauterine HBV infection is to be pregnant when HBV DNA and HBeAg are turned into negative after HBV inter-vention and treatment for women in reproductive age.
