After the concept of data curation and its application in foreign countries were described , the key points of data curation for data service in special libraries and related problems were analyzed according to the overall needs and changes of users in special libraries.

Objective:To establish the quality standard for Chuipencao tablets. Methods:Sedum sarmentosum Bunge was identi-fied by TLC. Quercetin, kaempferol and isorhamnetin were determined by HPLC. Results: The method of TLC was highly specific. The linearity was obtained within the range of 4.94-98.82 μg·ml-1(r =0.999 9) for quercetion, 4.94-98.82 μg·ml-1(r =0.999 9) for kaempferol and 1.07-21.36 μg·ml-1(r=0.999 9) for isorhamnetion. The average recovery was 103.1%(RSD =2. 2%,n=6), 100. 6%(RSD=2. 0%,n=6) and 100. 1%(RSD=2. 0%,n=6), respectively. Conclusion: The method is accu-rate with good reproducibility, which can be used as the quality control for Chuipencao tablets.

After the key technologies used in mobile reading service of library were compared , the authors pointed out that copyright and privacy protection were the major issues challenging the mobile reading service of library.Its development was prospected .

After the meaning, features and application models of CDP technology were described, its application in protecting data in libraries was studied with Medical Library of Chinese PLA as an example, showing that CDP technology can effectively protect the data, improve their safety, and insure the stable operation of professional sys-tems in Medical Library of Chinese PLA.

Drupal, a powerful content management system and content management framework, can provide a visiting interface for the mobile terminal equipments , especially the interface for the mobile APP program .How to imple-ment the information pushing function in mobile library using Drupal+PhoneGap was described by constructing the APP program model for information pushing and browsing in mobile library as an example.

Objective To discussed application effect of modified flowchart of preoperational articles in the operating room. Methods A group for the reconstructed flowchart was set up to look into the problems of traditional flowchart for articles preparation and then have the flowchart modified upon the found problems. The duration for article preparation and the flaw rate were compared between pre-and post-modification. Result The duration for preparation after modification was significantly shorter than that before modification and the flaw rate was significantly lower as well (P<0.001). Conclusion The modified flowchart for article preparation in the operation room can reduce the flaw rate and shorten the duration for article preparation, thus ensuring smooth operation.

Objective To examine the correlation of serum neutrophil gelatinase-associated lipocalin (NGAL) with dialysis adequacy,microinflammatory state and iron metabolism,and to assess the value of NGAL in identifying the dialysis adequacy in maintenance hemodialysis (MHD) patients.Methods A total of 150 MHD patients and 50 healthy control people were enrolled in the study.Clinical data were collected and serum NGAL,CRP,transferrin saturation,serum ferritin were measured.MHD patients were divided into adequacy group and non-adequacy group according to spKt/V value.Serum NGAL between two groups was compared and correlation of NGAL with spKt/V,inflammatory factors,and other clinical indexes was examined by Pearson,multivariate regression Logistic model and area under curve (AUC) of ROC.MHD patients were followed up for 3 months.Similar correlation analysis was carried out before and after follow up between two groups.Results Serum NGAL of MHD patients was higher compared to healthy people [(445.45±50.34) μg/L vs (50.02 ±6.45) μg/L].Among 150 MHD patients,95 were classified into adequacy group,while 55 into non-adequacy group according to spKt/V value.Serum NGAL was significantly higher in adequacy group as compared to non-adequacy group [(589.14±56.34) μg/L vs (360.13±46.23) μg/L,P＜0.05].Serum NGAL was positively correlated to spKt/V,CRP,TSAT [r=0.652,0.825,0.785,all P＜0.05],but not to serum ferritin.Serum NGAL was also correlated to spKt/V,CRP,TSAT by multivariate regression Logistic model.AUC showed that NGAL level could reflex the condition of dialysis adequacy.During the follow up,all adequacy patients remained the same adequacy status.Thirty-eight out of 55 non-adequacy patients were qualified for complete adequacy after intervention.The serum NGAL before and after intervention was (368.14±56.21) μg/L and (360.56±46.23) μg/L respectively without significant difference.Conclusions Serum NGAL is obviously higher in MHD patients with dialysis adequacy compared to those without dialysis adequacy.Serum NGAL is positively correlated to spKt/V,CRP,TSAT.NGAL can reflex the condition of dialysis adequate in MHD patients.

AIM To study the phenols from Vitex negundo Linn..METHODS The ethyl acetate fraction of 70％ ethanol extract from V.negundo was isolated and purified by silica,Sephadex LH-20 and ODS column,then the structures of obtained compounds were identified by spectral data.RESULTS Seven compounds were isolated and identified as luteolin-4'-O-β-D-glucopyranoside (1),isoorientin 6-O-caffeate (2),3,4,5-tricaffeoyl quinic acid (3),(+)-pinoresinol-4-O-β-D-glucoside (4),methyl isoferuloyl-7-(3,4-dihydroxyphenyl) lactate (5),benzyl 7-O-β-D-glucoside (6) and oresbiusin A (7).CONCLUSION All the compounds are isolated from this plant for the first time,and compounds 1,3,5-7 are first isolated from genus Vitex.

A new flavonoid glycoside, (-)-2S-8-methyl-5,7,4'-trihydroxyflavanone-7-O-β-D-glucopyranoside (1), along with five known ones, quercetin-3-O-(2"-galloyl)-α-L-arabinoside (2), kaempferol-3-O-α-L-arabinoside (3), guaijaverin (4), trifolin (5) and hyperin (6), was isolated from the leaves of Eucalyptus robusta. Their structures with absolute configurations were elucidated by NMR, HR-ESI-MS, CD spectra data and physicochemical methods. In addition, 2-6 were isolated from E. robusta for the first time.
