The attitude of librarians in hospital libraries (rooms) in Beijing area to open to community health service staff, the service they provided for them, and the difficulties they faced were investigated using questionnaires in or-der to provide reference for health administrative departments in making policies.

The analysis of 2013 circulating foreign and Chinese books in Library of Capital Medical University showed that the number of foreign and Chinese books classified into R Medicine and Healthand I Literaturewas the largest ,which thus provided the evidence for book acquisition ,book circulation and library holding develop-ment.Certain suggestions were put forward for improving the utilization of books, such as enforcing the acquisition and catalogue , and recommending books that should be bought .

Objective The paper applies Combination Evaluation Methods to the comprehensive evaluation of 31 cities' New RCMs condition in Fujian Province in 2007.Methods Four single Comprehensive Evaluation methods were employed to evaluate the results which were then combined by Combination Evaluation Methods.Results The results of Combination Evaluation Methods were more stable and accurate than those of single Comprehensive Evaluation methods.Conclusions The results of Combination Evaluation Methods are more stable and reliable.

Forty rats were randomly divided into four groups and intraperitoneal injection of 1%lidocaine 400mg/kg (group Ⅰ)、1%lidocaine-?-cyclodextrin 400mg/kg (group Ⅱ)、1%alkalinized lidocaine 400mg/kg(group Ⅰ)and 1% alkalinized lidocaine-?-cyclodextrin 400mg/kg(group Ⅳ) respectively. The results showed that there was a significant difference of lethal time between group Ⅰ and Ⅱ, and no significant difference between gronp Ⅲ and Ⅳ; the times of toxic and lethal effects of group Ⅲ and Ⅳ were shortened markedly as compared to group Ⅰ and Ⅱ. It is concluded that ?-cyclodextrin can postpone the release and absorbance of lidocaine,and alkalizer can weaken this action of ?—cyclodextrin.

In order to adapt to the changes in the training model of medical professionals and meet the new re-quirements of information literary recommended by ACRL, medical information literacy education was reformed with the5+3+Xtraining model of clinicians proposed by Capital Medical University as an example, namely strengthening meta-literacy training by establishing new framework of medical information literacy education, implementing open education with new teaching methods, building assistant teaching platform, increasing class hours,etc.

Objective To explore the accuracy rate of classical anatomical landmark technique ( anterior , central , and posterior ap-proach) for internal jugular vein (IJV) by ultrasound technique.Methods Sixty-four patients with selective operation were included in this study.The anesthetist marked the anterior approach , central approach, and posterior approach for internal jugular vein at 0°(neu-ral), 30°,and 80°of head rotation, respectively.The accuracy of each anatomical landmark were examined by other anesthetist with ul -trasound technique .Results The accuracy rate of anterior approach and central approach were significantly higher than posterior ap -proach at 0°of head rotation, respectively.The accuracy rate of anterior approach was higher than posterior approach at 30°of head rota-tion.The accuracy rate was similar among anterior , central, and posterior approach at 80°of head rotation.Conclusion The accuracy rate was different in different approach of anatomical landmark for internal jugular vein .

Objective To investigate the mechanism of the fluorouracil(FU)drug resistance and to prove deeply the role of serum dihydropyrimidine dehydrogenase(DPD)activity in patients with gastric cancer resistance to FU with the level of cell culture. Methods The peripheral blood was collected from 45 patients with advanced gastric cancer before chemotherapy to detect the activity of DPD by high performance liquid chromatography(HPLC).The patients were divided into two groups(high activity group and low activity group)according to the results. The FU drug inhibitory rate of gastric cancer cell cultured in vitro were tested with MTT to compare the effects of the two groups. Result The FU drug inhibitory rate of gastric cancer cell cultured in vitro was obviously lower in high activity group than that in low activity group,(47.6±±4.0)%,(53.7±8.0)%respectively. Conclusion The activity of serum DPD may be simple and convenient indicators in predicting the resistance to FU.

Objective To investigate the relationship between hepatic potential capacity and the pharmcodynarnics of rocuroniurn.Methods The indocyanine green (ICG) excretion test waspertormed one day before operation in 71 patients with decompensated hepatic cirrhosis scheduled to receive devascularization combined with splenectomy.On the basis of ICG retention at 15 min(ICGR_(15)),the patients were divided into groups of I_1(22 cases,ICGR_(15)≤10),I_2(35 cases,1020).Another 20 healthy people(group C)were taken as thecontrols.Rocuronium 0.6 mg/kg was intravenously infused and 0.3 mg/kg rocuronium、was addedwhen T_1 value recovered to 25%control value.The twitch high of adductor pollicis muscle wasrecorded.The time of onset,T1 maximum depression,the clinical duration of initial dose,and thespontanous recovery index were recorded.The clinical duration of repeated maintenance doses and themean dosage of each group were recorded as well.Results The onset time,25% TOF responsePeriod and the recovery index after operation were significantly prolonged in groups of I_2 and I_3compared with those in groups of C and I_1(P<0.05 or P<0.01).No response period of grouP I_3was longer than that of other three groups(P<0.0 1).When the maintenance dose of rocuronium wasadded for more than four times,the clinical action time also showed to be prolonged in an older of I_3>I_2＞I_1 and mean dose reduced in an order of I_3

Objective To investigate the effect of head extension angle to glottis exposure by using three-dimensional CT reconstruction sagittal plane images of upper airway.Methods There were 80 patients,aged 7-78 years old,who had been scanned by helical CT in the head and neck.Reconstructed images were obtained by AW4.4 workstation and the following parameter was measured:angle α(A0 group),the angle created by the upper central incisor and root of epiglottis(angular vertex) and midpoint of glottis.Reconstructed images were printed according to the actual size of human body in a ratio of 1∶ 1,then the images were cut off from the upper central incisor to root of epiglottis by a section of arcs.Increasing the degree of angle α by clockwise to hypothetically increase the angle of head extension.The glottis was exposed by using a paper-made laryngoscope(Macintosh) model,and the success rate of glottis exposure was recorded when the degree of angle α was respectively increased 10°(A10 group),20°(A20 group),and 30°(A30 group).Results Compared with A0 group,the success rate of glottis exposure increased significantly in A10 group,A20 group and A30 group.The success rate of glottis exposure in A20 group and A30 group was significantly higher than A10 group.Compared with A20 group,the success rate of glottis exposure obviously increased in A30 group.Conclusion Based on CT reconstruction images of upper airway,we can analog study the effect of head extension angle to glottis exposure.
