The cloning of promoter is important for studying the genetic engineering and the regulation of gene expression in plants. Two promoters Os772 and Os359, which are predicted to be highly expressed in the endosperm of rice from the EST database were cloned. After construction of the Os772∶∶GUS and Os359∶∶GUS expression vectors, they were transformed into rice. X-Gluc staining of transgenic plants showed that Os772 and Os359 can promote GUS gene expression in matured endosperm but not in root, stem, leaf and flower. This result indicates Os772 and Os359 are two rice endosperm-specific promoters.

Objective To investigate the changes of circulating miRNAs expression profiles in different subtypes of ischemic stroke according to the Trial of Org 10 172 in Acute Stroke Treatment.Methods We selected 16 patients diagnosed as acute ischemic stroke at first time in the Department of Neurology,the Affiliated Hospital of Medical College Qingdao University from November to December in 2012.They were divided into large artery atherosclerosis (LAA) stroke group (n =8) and small artery occlusive (SAO) stroke group (n =8).At the same time,8 healthy checkup subjects were selected as control.High-throughput sequencing was used to detect the expression profiles of miRNAs in the plasma,and the high-throughput sequencing results were validated by quantitative real-time polymerase chain reaction.We performed the miRNAs variance analysis and associated bioinformatics analysis.Results Thirty hundred and sixty-nine miRNAs were detected in LAA group,SAO group and the control group.We found remarkable differences (fold change >2,P <0.01) in the expression of 12 miRNAs,including let-7a-5p,miR-744-5p,etc.,between any two groups of the three groups.Thirty-four miRNAs,containing miR-126-5p,miR-23a-3p,miR-143-3p,etc.,had a lower expression (fold change >2,P <0.01)in LAA group than that in the control group.In comparison with the control group,miR-1304-3p and miR-451a were significantly down-regulated (fold change > 2,P < O.01),while 27 miRNAs were significantly up-regulated (fold change >2,P <0.01) in SAO group.The expression levels of miR-146b-5p,miR-23a-3p and miR-451 a were validated in accordance with the results of real-time PCR.Target gene prediction and functional analysis revealed that target genes regulated by differential expression of miRNAs were mainly associated with cell proliferation,adhesion,metabolism and other biological functions.Conclusion miRNAs are differently expressed in the plasma of LAA group,SAO group and healthy control group,which suggest that miRNAs might play different roles in the pathogenesis of LAA stroke and SAO stroke by regulating downstream target genes.

OBJECTIVE:
To investigate the rare earth elements(REEs) contents and distribution characteristics in nasopharyngeal carcinoma( NPC) tissue in Gannan region.
METHOD:
Thirty patients of NPC in Gannan region were included in this study. The REEs contents were measured by tandem mass spectrometer inductively coupled plasma(ICP-MS/MS) in 30 patients, and the REEs contents and distribution were analyzed.
RESULT:
The average standard deviation value of REEs in lung cancer and normal lung tissues was the minimum mostly. Light REEs content was higher than the medium REEs, and medium REEs content was higher than the heavy REEs content. REEs contents changes in nasopharyngeal carcinoma were variable obviously, the absolute value of Nd, Ce, Pr, Gd and other light rare earth elements were variable widely. The degree of changes on Yb, Tb, Ho and other heavy rare earth elements were variable widely, and there was presence of Eu, Ce negative anomaly(δEu=0. 385 5, δCe= 0. 523 4).
CONCLUSION
The distribution characteristic of REEs contents in NPC patients is consistent with the parity distribution. With increasing atomic sequence, the content is decline wavy. Their distribution patterns were a lack of heavy REEs and enrichment of light REEs, and there was Eu , Ce negative anomaly.
