Expert consensus on standardized TORCH laboratory detection and clinical application / 中华检验医学杂志

TORCH, which is considered as a series of pathogens, including the Toxoplasma gondii, Rubella virus, Cytomegalovirus or Herpes simplex virus, often infects the pregnant women to induce the the fetus or newborn infection by transplacental infection or exposure to contaminated genital tract secretions at delivery. Increasing evidence have been confirmed that the infection of TORCH may cause the miscarriage, premature birth, malformed fetus, stillbirth, intrauterine growth retardation, neonatal multiple organ dysfunction and other adverse pregnancy outcomes. For most TORCH-infections cases may lacking the effective treatments during pregnancy, and it is important to achieve the effacing monitoring of TORCH infections before and during pregnancy. The laboratory testing of TORCH has the great significance. However, the consensus opinions still need to improve the the standardization of TORCH testing process and the correct interpretation. Based on the characteristics of the TORCH detection method, this article gives a consensus opinion on the standardized detection and clinical application of TORCH from the laboratory perspective according to the characteristics and types of infection of different pathogens.

Correlation of serum interferon-inducible protein 16 level with pathogenesis of preeclampsia / 重庆医学

Objective To investigate serum interferon-inducible protein 16 (IFI16) level in the patients with preeclampsia (PE) and its correlation with PE pathogenesis.Methods Forty-five PE pregnant women in the Third Affiliated Hospital of Zhengzhou University from August 2015 to March 2016 were selected as the PE group and contemporaneous 30 healthy pregnant women undergoing the routine pregnant examination were selected as the control group.The biochemical indexes of serum urea,uric acid,creatinine,etc.were detected by using the automatic biochemical analyzer.The serum levels of IFI16 and ET-1 were measured by ELISA.Then the correlations between serum IFI16 level with these detected indicators were analyzed.The receiver operating characteristic (ROC) curve analysis was performed to evaluate the value of serum IFI16 for predicting PE disease.Results The serum IFI16 and ET-1 levels in the PE group were significantly higher than those in the control group (P<0.01).Furthermore the serum IFI16 level in severe PE was significantly higher than that in mild PE (P<0.01).Serum IFI16 level in PE was positively correlated with systolic blood pressure,diastolic blood pressure,24-h urine protein quantitation and serum ET-1 level,and negatively correlated with serum albumin.Serum IFI16 levels 14.47 ng/mL and 17.09 ng/mL as the critical values for predicting preeclampsia and discriminating between mild preeclampsia and severe preeclampsia has a higher sensitivity and specificity.Conclusion The high level of serum IFI16 in pregnant women has a certain correlation with PE pathogenesis and may be a novel biomarker for predicting PE occurrence.
