[Responses of spring corn growth and yield in a cold area of China to field warming at nighttime during pre-anthesis stage].

By using the facility for increasing free air temperature, a field experiment was conducted in a cold area of Northeast China to study the responses of the growth and yield of rain-fed spring corn to the field warming at nighttime during pre-anthesis stage. Under the field warming at nighttime, the nighttime temperature in 0-10 cm soil layer increased by 1.7 degrees C, and the soil moisture content had a slight decrease.

Novel GATA6 loss-of-function mutation responsible for familial atrial fibrillation.

Atrial fibrillation (AF) is the most commonly sustained cardiac arrhythmia, and confers a substantially increased risk of morbidity and mortality. Increasing evidence has indicated that hereditary defects are implicated in AF. However, AF is genetically heterogeneous and the genetic etiology of AF in a significant portion of patients remains unclear.

[The influence of positive end-expiratory pressure on central venous pressure in patients with severe craniocerebral injury].

Objective: To observe the impact of positive end-expiratory pressure (PEEP) on central venous pressure (CVP) in mechanically ventilated patients with severe craniocerebral injury.

Methods: A prospective, interventional, self-control study was conducted. Thirty severe craniocerebral injury patients with central respiratory failure were enrolled.

Huge gastric disopyrobezoar: a case report and review of literatures.

We reported a case of huge gastric phytobezoar. The gastric phytobezoar was successfully removed through gastrotomy after two failed attempts in endoscopic fragmentation and removal. Disopyrobezoars could be treated either conservatively or surgically.
