In the dominant winter wheat （WW）-summer maize （SM） double cropping system in the low plain located in the North China, limited access to fresh water, especially during dry season, constitutes a major obstacle to realize high crop productivity. Using the vast water resources of the saline upper aquifer for irrigation during WW jointing stage, may help to bridge the peak of dry season and relieve the tight water situation in the region. A field experiment was conducted during 2009-2012 to investigate the effects of saline irrigation during WW jointing stage on soil salt accumulation and productivity of WW and SM. The experiment treatments comprised no irrigation （T1）, fresh water irrigation （T2）, slightly saline water irrigation （T3：2.8 dS m-l）, and strongly saline water irrigation （T4：8.2 dS m-1） at WW jointing stage. With regard to WW yields and aggregated annual WW-SM yields, clear benefits of saline water irrigation （T3 ＆ T4） compared to no irrigation （T1）, as well as insignificant yield losses compared to fresh water irrigation （T2） occurred in all three experiment years. However, the increased soil salinity in eady SM season in consequence of saline irrigation exerted a negative effect on SM photosynthesis and final yield in two of three experiment years. To avoid the negative aftereffects of saline irrigation, sufficient fresh water irrigation during SM sowing phase （i.e., increase from 60 to 90 mm） is recommended to guarantee good growth conditions during the sensitive early growing period of SM. The risk of long-term accumulation of salts as a result of saline irrigation during the peak of dry season is considered low, due to deep leaching of salts during regularly occurring wet years, as demonstrated in the 2012 experiment year. Thus, applying saline water irrigation at jointing stage of WW and fresh water at sowing of SM is most promising to realize high yield and fresh irrigation water saving.

Maize (Zea mays L.), a staple crop grown from June to September during the rainy season on the North China Plain,is usually inter-planted in winter wheat (Triticum aestivum L.) fields about one week before harvesting of the winterwheat. In order to improve irrigation efficiency in this region of serious water shortage, field studies in 1999 and 2001, twodry seasons with less than average seasonal rainfall, were conducted with up to five irrigation applications to determineevapotranspiration, calculate the crop coefficient, and optimize the irrigation schedule with maize under mulch, as well asto establish the effects of irrigation timing and the number of applications on grain yield and water use efficiency (WUE)of maize. Results showed that with grain production at about 8 000 kg ha-1 the total evapotranspiration and WUE ofirrigated maize under mulch were about 380-400 mm and 2.0-2.2 kg m-3, respectively. Also in 2001 WUE of maizewith mulch for the treatment with three irrigations was 11.8% better than that without mulch. In the 1999 and 2001seasons, maize yield significantly improved (P = 0.05) with four irrigation applications, however, further increases werenot significant. At the same time there were no significant differences for WUE with two to four irrigation *** the 2001 season mulch lead to a decrease of 50 mm in the total soil evaporation, and the maize crop coefficient undermulch varied between 0.3-1.3 with a seasonal average of 1.0.

中国正处于社会转型期,社会矛盾凸显。生产力欠发达是人民内部矛盾产生的物质根源:生产力发展的多层次性和不平衡性,不能满足具有不同层次人们的需求;粗放型的经济增长方式导致无发展的增长。新旧体制交替是人民内部矛盾产生的制度根源:新体制加剧了旧矛盾,体制不完善形成了新矛盾。世界形势的变化和经济全球化的影响是人民内部矛盾产生的外部根源:苏联解体,社会主义运动陷入低潮;经济全球化浪潮进一步加剧了社会矛盾;西方文化大量涌入,思想文化也发生了嬗变。

川崎病,又称为皮肤黏膜淋巴结综合征,是一种全身急性血管炎性病变,属于自身免疫性疾病。目前,该疾病发病具体机制尚不明确,可能涉及核因子κB (nuclear factor-kappa B,NF-κB)信号通路参与的免疫反应、炎症反应、血管内皮损伤等诸多因素。尤其是川崎病合并心脏损伤患儿预后不佳,研究人员希望通过探索川崎病心脏损伤的具体发病机制,为临床诊断和治疗提供新的选择,并降低其发病率。该文就NF-κB信号通路在儿童川崎病心脏损伤中的机制进展做一综述,为后续研究提供理论指导。

Objective To explore the molecular mechanism of insulin resistance in the patients with polycystic ovarian syndrome (PCOS)Methods Polymerase chain reaction, silver staining-single strand conformation poly-morphism(PCR-SSCP) and DNA direct sequencing were used to detect the mutation of insulin receptor (INSR) gene in exon 17-21 with the abdominal wall adipose tissue from 31 patients with PCOS (PCOS Group) and 30 patients with pure hysteromyoma in reproductive lift (Control Group).Results Tiventy-two variant SSCP patterns in exon 17 of INSR gene were detected. Direct sequence analysis of exon 17 showed that homozygous nonsense mutation was two alleles single nucleotide polymorphism (SNP) at the codon 1058 (CAC→CAT). Exons 18-21were not detected with any significantly mutation. The INSR gene His1058C→ T substitution collecting rate and insulin resistance were significantly higher in the PCOS group than in the control group (P = 0. 0293, P<0. 05, P<0. 01). Conclusion It is suggested that the SNP in codon 1058 of the INSR gene might be related with the insulin resistance in PCOS patients, which has hereditary tendency. And the missense mutation,nonsense mutation and frameshift mutation at exons 18-21 in tyrosine protein kinase region of INSR gene for PCOS patients were not frequently observed.
