Transcriptomic and metabolomic analyses reveal the altitude adaptability and evolution of different-colored flowers in alpine Rhododendron species.

Understanding the molecular mechanisms and evolutionary process of plant adaptation to the heterogeneous environment caused by altitude gradients in plateau mountain ecosystems can provide novel insight into species' responses to global changes. Flower color is the most conspicuous and highly diverse trait in nature. Herein, the gene expression patterns, evolutionary adaptation and metabolites changes of different-colored flowers of alpine Rhododendron L.

Exploration of common bile duct for treating hepatic cystic echinococcosis.

Objective: To compare the clinical efficacy of exploration of common bile duct through cystic duct or T type tube in CE patients.

Methods: One hundred and fifty six patients with chronic CE received decompression of biliary tract from January 2007 to December 2012 were included. Exploration of common bile duct was performed through cystic duct (n=102) or T type tube (n=54).

[Characteristics of the PAH gene mutation in Chinese patients with phenylketonuria in Xinjiang].

Objective: To study the characteristics of the PAH gene mutation in patients with phenylketonuria (PKU) in Xinjiang area.

Methods: The mutations in exons 3, 5, 6, 7, 11 and 12 and the flanking intronic sequence of the PAH gene were detected by PCR/SSCP analysis and direct DNA sequencing in 46 PKU patients.

Results: Twenty different mutations were found in 68/92 alleles (73.
