The effects of adsorption time, solid-liquid ratio, sample concentration, flow rate on the adsorption properties of supported ionic liquids(the N-methylimidazolium functionalized silica, SilprMin) for flavonoids were investigated. The results indicated that the adsorption equilibrium for tested compounds, genistein, luteolin and quercetin, was achieved within 30 min, the adsorption efficiencies of these three compounds were improved with the increase of solid-liquid ratio, and decreased with the increase of their concentrations. Moreover, the adsorption isotherm data of the three tested compounds were in good concordance with the Langmuir model. The saturated adsorption capacity of SilprMim for genistein, luteolin and quercetin was 47.7, 52.5 and 63.2 mg/g, respectively. Adsorption efficiency of SilprMim could reach more than 90% at a sample flow rate of 0.5～1.5 mL/min. Using methanol as eluent, the saturated desorption efficiencies of genistein, luteolin and quercetin were 86.1%, 83.3% and 84.6%, respectively. The elution order of the three tested flavonoids was genistein, luteolin and quercetin. SilprMim had strong adsorption and separation capacity for three tested flavonoids, which was hopeful to be applied in separation and purification of naturally occurring flavonoids.

Objective To supply the fastest and most effective first aid for patients with the least medical workers and within the shortest time after the occurrence of emergent public health accidents by application of emergency management. Methods We carried out retrospective invetigations about 55 great medical succors from the year of 2004 to 2006.Results Application of emergency nursing management played a pivotal role in these 55 great medical succors. The medical workers handled all the emergencies without confusion and a large number of patients got first aid in time. Conclusion It could facilitated the first aid for emergent public health accidents by application of emergency nursing management.

Objective To investigate the relationship between tumor subclassifieation and the clinicopathologic features and prognosis of patients with gastrointestinal diffuse large B-cell lymphoma (DLBCL). Method From June 2000 to June 2007, 63 gastrointestinal DLBCL cases were enrolled. Immunohistochemical staining was performed to detect CDIO, Bcl-6 and MUM1 expression. Tumors were subclassified according to CDIO, Bcl-6 and MUM1 expression. Results CD10 expression was positive in 13 cases. Bcl-6 expression was positive in 53 cases. MUM1 expression was positive in 52 cases. According to the expression of CD10, Bcl-6 and MUM1, 17 cases(27%) were of germinal center B cell-like (GCB) DLBCL and 46 cases (73%) were of non-GCB. There was a significant difference in local lymph node metastasis between GCB group and non-GCB group, but there was no significant difference in terms of tumor size and infiltrate depth between the two subgroups. The survival time of patients in GCB group(76 months) was significantly longer than that of non-GCB group (28 months). Among cases receiving postoperative chemotherapy (CHOP), the survival of GCB group (76 months) was longer than non-GCB group (24 months). All 4 GCB cases and 4 non-GCB cases under R-CHOP chemotherapy are alive (22 ～ 47 months). Conclusion Gastrointestinal DLBCL subclassification is closely correlated with local lymph node metastasis, and this in combination with the expression of CD10 could be used to predict the prognosis of patients with gastrointestinal DLBCL.

Objective To investigate the relationship between the color doppler sonography and contrast-enhanced echocardiography(CEE)in assessment of intrapulmonary shunting in patients with hepatopulmonary syndrome and HIF-1α,iNOS and portal hemodynamic.Methoods To examine the portal vein diameter and blood flow velocity by color Dop-pler,and intrapulmonary shunting by contrast-enhanced echocardiography(CEE).The expressions of HIF-1α and iNOS in serum were determined by ELISA in the normal,hepatocirrhosis amalgamating HPS and unamalgamating HPS separately.Comparison of HIF-1α and iNOS in plasma was carried out and relationship between the portal hemodynamic and the intra-pulmonary shunting was examined in three groups.Results The levels of HIF-1α and iNOS in hepatocirrhosis amalgamating HPS were higher than those in unamalgamating HPS,the diameter of portal vein dilated and the velocity of portal vein dropped,there was correlation(P＜0.05).There were positive correlation with intrapulmonary shunting.Conclusion The color doppler sonography and contrast-enhanced echocardiography (CEE)which reflected HIF-1α,iNOS and the hemodynamic played an role in developing of HPS,and was available to early examine change of intra-pulmonary vessel.

Unfavorable psychic reactions or psychological crisis always occur in patients preliminarily diagnosed with cancer.By analyzing the psychological activities and affecting factors,we try to discuss the measures of psychological crisis intervention for patients preliminarily diagnosed with cancer.

Objective:To determine whether implantation of an intraocular lens(IOL) with a modified prolate anterior surface results in reduced spherical aberration and improved contrast sensitivity after cataract surgery.Methods: Consecutively 72 eyes were selected from 53 senile cataract patients who had received phacoemulsification and IOL implantation in Peking University Eye Center.Each was randomly assigned to receive Tecnis Z9001 IOL or Sensar AR40e(both made by AMO).Three months after operation,the eyes underwent several tests including visual acuity,optometry and wavefront aberration examination.Mesopic contrast sensitivity test was measured with ROLAND BA-4 Contrastometer.Results: The eyes treated with Tecnis Z9001 had significantly less spherical aberration.The eyes treated with Tecnis IOL got lower C12 coefficient and RMS4 than those with Sensar AR40e(P value
