The Root Endophytic Fungi Community Structure of from Four Representative Provinces in China.

is a good forage grass with high biomass production and crude proteins. However, little is known about the endophytic fungi diversity of , which might play an important role in the plant's growth and biomass production. Here, we used high throughput sequencing of the Internal Transcribed Spacer (ITS) sequences based on primers ITS5-1737 and ITS2-2043R to investigate the endophytic fungi diversity of roots at the maturity stage, as collected from four provinces (Shaanxi province, SX; Fujian province, FJ; the Xinjiang Uyghur autonomous prefecture, XJ and Inner Mongolia, including sand (NS) and saline-alkali land (NY), China).

Root-Associated Endophytic Bacterial Community Composition of from Four Representative Provinces in China.

, a source of bio-energy with high biomass production, is a species that contains high crude protein and will be useful for solving the shortage of forage grass after the implementation of "Green for Grain" project in the Loess plateau of Northern Shaanxi in 1999. Plants may receive benefits from endophytic bacteria, such as the enhancement of plant growth or the reduction of plant stress. However, the composition of the endophytic bacterial community associated with the roots of is poorly elucidated.

[Relative factors of expectant management of ectopic pregnancy].

Objective: To analyze select patients of ectopic pregnancy for expectant management.

Methods: Retrospective analyses were conducted for the relative factors of 180 cases of ectopic pregnancy with expectant management at Department of Family Planning of our hospital from August 2004 to January 2012. Their general clinical data, clinical manifestations and laboratory tests were collected.
