Value of shear wave elastography in the diagnosis and evaluation of cervical cancer.

The aim of the present study was to explore the value of shear wave elastography (SWE) in the differential diagnosis of cervical disease and to evaluate the infiltration of cervical cancer. A total of 40 inpatients with cervical cancer, 40 inpatients with cervical benign lesion and 40 healthy volunteers encountered between October 2014 and January 2017 were enrolled. All patients and volunteers underwent conventional ultrasound (US) and SWE examinations.

8-bromo-7-methoxychrysin targets NF-κB and FoxM1 to inhibit lung cancer stem cells induced by pro-inflammatory factors.

We have previously reported that 8-bromo-7-methoxychrysin (BrMC), a novel synthetic derivative of chrysin, was demonstrated anti-tumor activities against several human cancers, including lung cancer. Interaction between inflammation and cancer stem cell are recently increasingly recognized in tumorigenesis and progression. The purpose of this study was to investigate whether BrMC inhibits lung cancer stemness of H460 cells induced by inflammatory factors (TGF-β combined with TNF-α) and its potential mechanism.

Evaluation of ecosystem service value of the grape industry at the eastern foot of Helan Mountain, Ningxia, China.

Using statistical data from Statistics Bureau of Ningxia Hui Autonomous Region, the Grape Industry Development Bureau of Ningxia Hui Autonomous Region, and National Bureau of Statistics, ecosystem service value of grape industry at the eastern foot of Helan Mountain in Ningxia was evaluated from eight facets, i.e., food production, carbon fixation and oxygen release, air purification, soil conservation, water-holding, water conservation and efficiency, eco-tourism, and ecological poverty alleviation.

[Carbon footprints of major staple grain crops production in three provinces of Northeast China during 2004-2013.].

Northeast China is one of the most important farming regions in China, due to its great contribution to national food security. Crop production is a main source of carbon emission. To assess the differences in carbon footprints of major grain crop production will benefit the achievement of low carbon agriculture.

[Effects of shading and plant density on ear development and plant productivity of spring maize in Northeast China].

It is important to investigate the effects of shading on maize ear characteristics and yield, which can provide references to variety breeding and agronomic technique improvement for coping with climate change and dense planting. An experiment was carried out with two varieties (compact type hybrid ZD909, flat type hybrid ND4) and two planting densities (45000 and 90000 plants·hm) at Gongzhuling City, Jilin Province. Two treatments were conducted for each variety and planting density, including shading (with a shading degree of 65% from small bell mouth stage to mature stage) and no shading treatment (CK).

[Effects of tillage patterns on photosynthetic and chlorophyll fluorescence characteristics of maize in rainfed area of Northeast China].

In 2010-2011, a field experiment was conducted in Northeast China to evaluate the effects of different tillage patterns on the temperature and moisture in topsoil layer and the leaf photosynthesis and chlorophyll fluorescence of maize. The effects of tillage patterns on the soil temperature and moisture mainly manifested at sowing-jointing stage. In treatments flat planting with ridging at early jointing stage (PL) and flat planting without ridging (PP), the soil moisture content at the depth of 0-40 cm was significantly higher than that in treatment ridge planting (LL), with the increment being 5.
