[Spatial and temporal characteristics of flue-cured tobacco water requirement and irrigation requirement index in Yunnan Province, China].

Based on the daily meteorological data of 124 agricultural meteorological sites during 1977-2010 in Yunnan Province, using recommended Penman-Monteith formula by FAO, water requirement and irrigation requirement index in the growth period of flue-cured tobacco were calculated to analyze their spatial and temporal characteristics and change patterns. The results showed that water requirements of flue-cured tobacco in root extending, vigorous, mature periods and field growth period during 1977-2010 were 76.73-174.

Two single nucleotide polymorphisms in TSLP gene are associated with asthma susceptibility in Chinese Han population.

Background: Asthma is a chronic inflammatory disease of the airway that is mediated by T-helper 2(TH2) cells. Thymic stromal lymphopoietin (TSLP) can aggravate asthmatic lung inflammation by activating dendritic cells (DCs) to promote TH2 differentiation. TSLP promoter polymorphisms are associated with susceptibility to bronchial asthma in Japanese population.
