The great Wenchuan earthquake （Ms= 8.0） in 2008 caused severe damage in the western part of the Chengdu Plain. Soil liquefaction was one of the major causes of damage in the plain areas, and proper evaluation of liquefaction potential is important in the definition of the seismic hazard facing a given region and post-earthquake reconstruction. In this paper, a simplified procedure is proposed for liquefaction assessment of sandy deposits using shear wave velocity （V）, and soil liquefaction from the Banqiao School site was preliminarily investigated after the earthquake. Boreholes were made at the site and shear wave velocities were measured both by SASW and down-hole methods. Based on the in-situ soil information and V profiles, the liquefaction potential of this site was evaluated. The results are reasonably consistent with the actual field behavior observed after the earthquake, indicating that the proposed procedure is effective. The possible effects of gravel and fines contents on liquefaction of sandy soils were also briefly discussed.

Non-point source pollution is an important factor that affects the water quality of the Weihe *** study the effect of the pollution on the water quality of the Weihe River,five flood events and three normal discharge events during non-flood period were monitored from July to December in 2006,at the Lin-tong *** order to identify how sediment influenced the water quality of the river,raw and supernatant samples taken from the monitored events were *** samples were siphoned from 5 cm below the water surface of the raw samples at the lab afterwards the raw samples were shaken up and laid for 30 minutes in the *** results indicated that:1) The concentrations of SS,COD,TP and TN in the raw samples from flood events were higher than those from normal discharge *** higher values of the COD,TP and TN in the raw samples resulted from natural humic matters in surface soil.2) The load transport rate of analyzed water quality indexes increased gradually to its maximum and then drop down,matching that in the discharge *** concentrations of SS,NH-N,NO-N,NO-N,COD,and TP in the raw samples increased initially and then decreased,while the concentration of dissolved orthophosphate and TN in the raw samples decreased gradually and then *** peak time of concentration and load transport rate of SS as well as COD,TP and TN in the raw samples were close to or lagged behind the time of peak flow. Generally,the peak time of concentration and load transport rate of dissolved orthophosphate, dissolved total-phosphate,NH-N,NO-N,and NO-N occurred prior to the time of peak flow.3) The mean concentration method was used to calculate the NPS pollution load at Lin-tong section,and the results are *** 2006,the proportions of the NPS pollution load to the total load for COD,TP, TN and inorganic nitrogen were more than 30%.

Ultraviolet (UV) irradiation is a DNA-damaging agent that triggers apoptosis through both themembrane death receptor and mitochondrial apoptotic signaling ***,a pro-apoptotic Bcl-2family member,is important in most cell types to apoptosis in response to DNA *** this study,arecombinant plasmid,YFP-Bid-CFP,comprised of yellow and cyan fluorescent protein and a full length Bid,was used as a fluorescence resonance energy transfer analysis (FRET) *** the FRET techniquebased on YFP-Bid-CFP,we found that Bid activation was initiated at 9±1 h after UV irradiation,and theaverage duration of the activation was 75±10 *** activation coincided with a collapse of the mitochondrialmembrane potential with an average duration of 50±10 min. When cells were pretreated with Z-IETD-fmk(caspase-8 specific inhibitor) the process of Bid activation was completely inhibited,but the apoptosis wasonly partially affected.Z-DEVD-fmk (caspase-3 inhibitor) and Z-FA-fmk (non asp specific inhibitor) didnot block Bid ***,the endogenous Bid activation with or without Z-IETD-fmk in responseto UV irradiation was confirmed by Western *** summary, using the FRET technique,we observedthe dynamics of Bid activation during UV-induced apoptosis and found that it was a caspase-8 dependentevent.

Objective: To observe the relative specialty of the therapeutic effect of acupuncture of Baihui (百会 GV 20), Shuigou (水沟 GV 26) a nd Shenmen (神门 HT 7) in the treatment of vascular dementia (VD) patients. Methods: F ifty VD patients were randomly divided into routine treatment group (control gro up), Baihui (GV 20) group (GV 20 group), Shuigou (GV 26) group (GV 26 gr oup), Shenmen (HT 7) group (HT 7 group) a nd GV 20+GV 26+HT 7 group (joint treatment group), with 10 cases in ea ch group. In control group, acupoints used were Jianyu (肩NFDA1 LI 15), Quchi (曲池 L I 11), Waiguan (外关 TE 5), etc. (which were also used in the other four groups) on the paralyzed side. The treatment was conducted once a day except weekends, 20 session s all together. Clinical Dementia Rating Scale (CDR), Mini-Mental State Examin at ion (MMSE) test, Blessed Dementia Rating Scale (BDR) and Clinical Neurological D eficit Rating (CNDR) were used to assess the patients’ intelligence state befor e and after acupuncture treatment. Results: After acupuncture tr eatment, the VD patients’ intelligence in all the five groups was improved at different degrees . Additional acupuncture of each of GV 20, GV 26 and HT 7 had a remarkable e ffec t in improving the VD patients’ fluid intelligence, and could obviously promote their abilities of temporal orientation, spatial orientation and figure drawing ; and additional joint acupuncture of the three acupoints could improve their co gnitive and non-cognitive functions, such as reducing the severity of dementia , raising the temporal orientation, spatial orientation, calculation, short-term m emory and figure drawing abilities, and improving their activities of daily livi ng and personality. Besides, acupuncture of GV 20 could improve the abilities of calculation and short term memory, and correct the personality change of VD pat ients, while acupuncture of GV 26 could improve the abilities of naming and sh or t-term memory. Conclusion: Acupuncture of GV 20, GV

In cereal species such as wheat (Ttiticum aestivum) and barley (Hordeum vulgare), many studies have indicated that VERNALIZATION 1 (VRN1) functions as a flowering promoter, which activates florigen gene expression. The wheat florigen gene Wheat FLOWERING LOCUS T (WFT, which is identical to VRN3) is an integrator of the vernalization, photoperiod and autonomous pathways in wheat flowering, and the WFT expression is correlated with the VRN1 expression. VRN1 encodes an APETALA1/FRUITFULL-like MADS-box transcription factor which expression is induced by vernalization, leading to flowering thorough up-regulation of
