C-banding and AgNOR-staining were still effective complementary methods to indentify chromosomal heteromorphisms and some structural abnormalities in prenatal diagnosis.

Background: In prenatal diagnosis, CMA has begun to emerge as a favorable alternative to karyotype analysis, but it could not identify balanced translocations, triploidies, inversion and heteromorphisms. Therefore, conventional cytogenetic and specific staining methods still play an important role in the work-up of chromosome anomaly. This study investigated the application of C-banding and AgNOR-staining techniques in prenatal diagnosis of chromosomal heteromorphisms and some structure abnormalities.

[Vertical gradients of water supply and demand in Taihang Mountains, China].

Taihang Mountains plays a key role in water supply for the North China Plain, even though it has the ecological disadvantages of less water and soil. Research on the vertical characteri-stics of water supply and demand in Taihang Mountains is beneficial for the sustainable management of the mountain ecosystem. Here, we quantitatively evaluated water provision in the Taihang Mountains using remote sensing data and InVEST model.

[Simulation study on the effects of climate change on aboveground biomass of plantation in southern China: Taking Moshao forest farm in Huitong Ecological Station as an example].

Global climate warming has significant effect on territorial ecosystem, especially on forest ecosystem. The increase in temperature and radiative forcing will significantly alter the structure and function of forest ecosystem. The southern plantation is an important part of forests in China, its response to climate change is getting more and more intense.

De novo hepatitis B virus infection from anti-HBc-positive donors in pediatric living donor liver transplantation.

Objective: The aim of this study was to analyze the incidence and risk factors of de novo hepatitis B virus (HBV) infection from hepatitis B core antibody (anti-HBc)-positive donors in pediatric living donor liver transplantation (LDLT).

Methods: We retrospectively analyzed 46 recipients without pre-liver transplantation (LT) HBV infection evidence who underwent LDLT from October 2006 to May 2011 in our center. HBV markers, including hepatitis B surface antigen (HBsAg) and antibody (anti-HBs), anti-HBc, hepatitis B e antigen (HBeAg) and antibody (anti-HBe) were determined in both donors and recipients before LT and in recipients after LT.

Prediction of early hepatic artery thrombosis by intraoperative color Doppler ultrasound in pediatric segmental liver transplantation.

Early hepatic artery thrombosis (eHAT) after transplantation is associated with a high incidence of graft failure and mortality in pediatric segmental liver transplantation (LT). The evaluation of intraoperative color Doppler ultrasound (CD-US) parameters and their sensitivity and specificity for the prediction of eHAT were important. Pediatric segmental LTs were performed in 49 consecutive patients from October 2006 to December 2010 in our hospital.
