Many kinds of medicinal ingredients occur in that have good clinical efficacy, conferring on this species its high medicinal development value. However, with a rapidly changing global climate, it is increasingly imperative to study the factors affecting the habitat distribution and survival of species. We predicted the current and future distribution areas of suitable habitats for , analyzed the importance of environmental variables in influencing habitat shifts, and described the alterations to suitable habitats of in different periods (modern, 2050s, and 2070s) and scenarios (RCP2.

This rare and threatened orchid lacks molecular resources for phylogenetic and barcoding analysis. Therefore, we sequenced and assembled seven complete plastomes of Chiloschista to analyse the plastome characteristics and phylogenetic relationships and conduct a barcoding investigation.

The lack of resolution achieved through the analyses of previous molecular sequences from one or a few markers has long confounded phylogenetic estimation and generic delimitation. Here, we present large-scale phylogenomic data to compare the plastome structure of the two main clades (Goodyera and Cheirostylis) in this subtribe and further adopt two strategies, combining plastid coding sequences and the whole plastome, to investigate phylogenetic relationships.

Oil leakage, which is inevitable in the process of extraction, processing, transportation and storage, seriously undermines the soil and groundwater environment. Surfactants can facilitate the migration and solution of oil contaminants from nonaqueous phase liquid (NAPL) or solid phase to water by reducing the (air/water) surface tension, (oil/water) interfacial tension and micellar solubilization. They can effectively enhance the hydrodynamic driven remediation technologies by improving the contact efficiency of contaminants and liquid remediation agents or microorganism, and have been widely used to enhance the remediation of oil-contaminated sites.

Methods: From May 2011 to March 2014, a retrospectively analysis was conducted among 31 patients with knee valgus (mild in 10 cases, moderate in 8 cases and severe in 13 cases based on Keblish grade).
Objective: To investigate the risk factors and prognosis influential factors of acute kidney injury (AKI) after cardiac surgery.
Methods: The clinical data of patients who were hospitalized and underwent cardiac surgery from April 2009 to May 2011 were collected prospectively. Demographic characteristics, types of surgeries, preoperative renal function, pre- and intra-operative conditions and clinical outcomes, etc were recorded.
Background: Residual renal function (RRF) recently has been confirmed to be a significant predictor of morbidity and mortality in hemodialysis (HD) patients. As RRF is not exactly the same with 24-h residual urine volume, the aim of our study is to evaluate the association of residual urine volume with acute ischemic stroke (AIS) among HD patients.
Methods: 282 patients starting chronic HD in our center during January 2005 and December 2008 were enrolled.
