The Longmenshan fault is a thrust fault which runs along the base of the Longmen Mountains in Siehuan province, southwestern China. The southern segment of the fault had two distinct responses to the Ms 8 Wenehuan and Ms 7 Lushan earthquakes. This study determines characteristics of the structural geology of the Longmenshan fault to evaluate how it influenced the two aforementioned earthquakes. This research was done within a Geo- information Technologies （GiT） environment based on multi-source remote sensing and crustal movement data extracted from the Global Positioning System （GPS）. The spatial distribution of the southern segment of the Longmenshan fault zone was comprehensively analyzed to study both earthquakes. The study revealed that the Wenehuan and Lushan earthquakes occurred on two relatively independent faults. In addition, there was a nearly constant-velocity crustal movement zone between the two epicenters that probably had a compressive stress with slow motion. Furthermore, the central fault and a mountain back fault gradually merged from north to south. The Lushan earthquake of the Wenchuan earthquake. was not an affershock The research showed that fault zones within 30-50 km of State Highway 318 are intensive and complex. In addition, crustal movement velocity decreased rapidly, with a strong multi-directional shear zone. Thus, activity in that zone was likely stronger than in the northern part over the medium to long term.

OsRacD, belonging to rice （Oryza sativa L. ssp. japonica） Rho family of the small GTPases, is a pivotal gene involved in rice photoperiod fertility conversion of photoperiod sensitive genic male sterile rice which influences the rice fertility via controlling the pollen tube growth. Using OsRacD as bait, two GDP dissociation inhibitor genes designated as OsRhoGDI1 and OsRhoGDI2 were screened by yeast two-hybrid system. To further study the regulation mechanism of OsRhoGDIs, and also the relationships between OsRhoGDIs and OsRacD, the upstream regulation sequences of OsRhoGDI1 and OsRhoGDI2 were cloned by PCR, and the cis-elements in the promoters were predicted using internet tools in this study. The results showed that there were several kinds of response elements, such as phytohormone response elements, lightregulated elements and adversity induced elements in the promoters of OsRhoGDIs, some of which were similar. Comparing with the promoter of OsRacD, several pollen tube germination related elements were found. On one hand, the expression and regulation mechanism of OsRhoGDIs were complex, they may be regulated by several signaling pathways commonly, and the regulation mechanisms were similar to some extent. On the other hand, it was suggested that the fertility of photoperiod sensitive genic male sterile rice may be controlled by the cooperative expression of OsRhoGDIs and OsRacD.

Mitogen activated-protein kinases （MAPKs） are important components in signal transduction pathways responding to various biotic and abiotic stresses. An MAPK gene, OsMPK14 （GenBank Accession No. GQ265780） from rice （Oryza sativa L.）, was cloned by RT-PCR. The full-length cDNA of OsMPK14 consists of 1660 bp in size, containing an open reading frame of 1629 bp, which encodes a 542-amino-acid polypeptide and has a typical protein kinase domain and a phosphorylation activation motif TDY. Sequence alignment and analysis revealed that OsMPK14 was located on rice chromosome 5, and composed of nine exons and eight introns in the coding region. Semi-quantitative RT-PCR was performed to detect the expression patterns of OsMPK14 in rice shoots and roots under darkness, drought, high salinity, low temperature and abscisic acid treatments. The OsMPK14 mRNA was induced by abscisic acid, low temperature and high salinity, but weakly inhibited by drought. In addition, the expression of OsMPK14 was up-regulated in roots, but down-regulated in shoots by light. The results indicate that OsMPK14 could be implicated in diverse rice stimuli-responsive signaling cascades, and its expression might be regulated by multiple factors.

Objective To compare the effectiveness of immunofluorescence and polymerase chain reaction （PCR） in detecring human papilloma virus （HPV） in condyloma acuminata （CA）. Methods HPVs in CA tissues from 60 patients were detected by immunofluorescence and PCR, respectively. Different subtypes of HPVs were also identified with restriction fragment length polymorphism （RFLP） . Resuits The positive detective rates of immunofluorescence and PCR were 56. 67 % （34/60） and 96. 67 % （58/ 60）, respectively （ P 〈 0. 01 ）. RFLP results showed HPV6 and HPV11 were the main subtypes in the detected virus, which accounted for 98.28%. Conclusion The sensibility of PCR is superior to that of immunofluorescence.
