[Effects of shading on the nitrogen redistribution in wheat plant and the wheat grain quality].

Taking winter wheat (Triticum aestivum L.) cultivars Yangmai 158 (shading-tolerant) and Yangmai 11 (shading-sensitive) as test materials, this paper studied the effects of shading at the stages from jointing to maturity on the plant N redistribution, grain yield, and grain- and dough quality of the cultivars. The treatments were non-shading, 22% shading, and 33% shading.

[Effects of shading on wheat grain starch quality and redistribution of pre-anthesis stored nonstructural carbohydrates].

This paper studied the effects of shading in the period from jointing to maturity on the grain yield, starch content, and starch paste traits of two winter wheat (Triticum aestivum L.) cultivars, shading-tolerant Yangmai 158 and shading-intolerant Yangmai 11, and analyzed the relationships of the redistribution of total soluble sugars stored before anthesis in vegetative organs with the grain yield, starch content, and starch paste parameters of the cultivars. The results showed that shading decreased the redistribution of pre-anthesis stored total soluble sugars in vegetative organs to reproductive organ, resulting in the decrease of grain yield, and significantly decreased the amylopectin content but had no effects on the amylose content in grains, inducing a significant decrease in the ratio of amylopectin to amylase content in the grains.

[The short-term outcomes of patients with acute leukemia treated by thalidomide].

Objective: To study the efficacy of thalidomide for treating acute leukemia (AL).

Methods: 38 cases of AL were studied. 27 of the 38 cases receiving initial treatment were randomly divided into two groups, one treated with routine chemotherapy plus thalidomide (A) and the other with routine chemotherapy alone (B).
