Ensure the accuracy and consistency of biochemical analyzer test results: Chemometrics for instrument and inter-instrument item comparison in Chinese hospital laboratory.

Biochemical analyzers are vital instruments that utilize the principle of photoelectric colorimetry to quantify a specific chemical composition in body fluids. This analysis provides critical data for the diagnosis, treatment, prognosis, and overall health status of various diseases in clinical practice. However, the performance of a biochemical analyzer can vary significantly between different brands or over time within the same brand.

Cordblood-Based High-Throughput Screening for Deafness Gene of 646 Newborns in Jinan Area of China.

Objectives: Infants with slight/mild or late-onset hearing impairment might be missed in universal newborn hearing screening (UNHS). We identified the mutation hot spot of common deaf gene in the newborns in Jinan area population by screening the mutation spot with neonate cord blood, in order to make clear whether the neonate cord blood for screening is feasible.

Methods: Six hundred and forty-six newborns were subjected to both UNHS and genetic screening for deafness by using neonate cord blood.

Combination of hearing screening and genetic screening for deafness-susceptibility genes in newborns.

The aim of this study was to determine the clinical significance of the results of screening of newborn hearing and the incidence of deafness-susceptibility genes. One thousand newborn babies in the Handan Center Hospital (Handan, China) underwent screening of hearing and deafness-susceptibility genes. The first screening test was carried out using otoacoustic emissions (OAEs).

[Effects of land use change on soil erosion intensity in small watershed of Loess Hilly Region: a quantitative evaluation with 137-Cesium tracer].

Based on the land use change data and by using 137Cs tracer technique, this paper studied the change process of soil erosion intensity in Yangjuangou watershed in Loess Hilly Region. Since the 1980's, the land use intensity in the watershed decreased gradually. In 1980-2006, the slope arable land decreased from 94.
