[Spatiotemporal variation of vegetation phenology in the Daxing'an Mountains stratified by eco-geographical regions.].

Vegetation phenology is a good indicator of climate change, because of the close correlation between vegetation and climate. The Daxing'an Mountains, located in Chinese northernmost region, are more sensitive to climate change. Researching the spatio-temporal variation of vegetation phenology in this region is of great significance for assessing the influence of global change on terrestrial ecosystem.

Analyses of phenotype and ARGOS and ASY1 expression in a ploidy Chinese cabbage series derived from one haploid.

The aim of this research was to improve our understanding of how ploidy level influences phenotype and gene expression in Chinese cabbage (Brassica rapa L. ssp. pekinensis).

Generation and characterization of Brassica rapa ssp. pekinensis - B. oleracea var. capitata monosomic and disomic alien addition lines.

Five monosomic alien addition lines (MAALs) of Brassica rapa ssp. pekinensis - B. oleracea var.

Influence of Helicobacter pylori genotype on triple eradication therapy.

Background: The efficiency of Helicobacter pylori eradication varies geographically, as do many parameters that might affect therapeutic efficiency. The aims of this study were to investigate the relationship between different genotypes of H. pylori and bacterium-related histopathological lesions in patients with duodenal ulcer and to determine the effect of genotype on triple eradication therapy.

Clinical and genetic study of SPG6 mutation in a Chinese family with hereditary spastic paraplegia.

Mutations in the NIPA1 gene cause autosomal dominant hereditary spastic paraplegia (ADHSP). To date, little is known about the relationship between genotype-phenotype correlation. In order to examine the gene mutation associated with the genotype-phenotype of Chinese kindred with ADHSP, linkage analysis and mutation detection were performed.

Proton pump inhibitor improves breath marker in moderate asthma with gastroesophageal reflux disease.

Background: Gastroesophageal reflux disease (GERD) influences the symptoms of asthma with acid and oxidative stress.

Objectives: The purpose of this study was to determine the usefulness of measurement of the acid stress marker pH and the oxidative stress marker 8-isoprostane by exhaled breath condensate in proton pump inhibitor (PPI) therapy effect on moderate asthma patients with GERD.

Methods: The pH and the concentration of 8-isoprostane were measured in the exhaled breath condensate of patients with moderate asthma (n = 36) and healthy subjects (n = 26).
