After a description of the elements in constructing an intelligent library, innovative service, and the role of intelligent librarians, the new ideas the intelligent librarians should have were pointed out with the hormonal development of intelligent library stressed .

One hundred and six patients with hip fracture admitted in hospital from 2011 to 2014 were randomly divided into two groups: 52 patients received celecoxib and parecoxib ( trial group ) and 54 patients received oxycodone hydrochloride and bucinnazine (control group).On d1 and d7 after the surgery, serum levels of C-reactive protein[(26.2 ±5.4) and (10.4 ±2.8) mg/L], tumor necrosis factor-α[(40.6 ±6.1) and (31.8 ±5.3)ng/L], interleukin-6 [(22.3 ±5.7) and (18.3 ±5.2) ng/L] and prostaglandin E2 [(181.1 ± 19.4) and (153.3 ±25.8) ng/L] in trial group were all significantly lower than those in control group [(46.1 ± 14.0) and (22.1 ±5.2)mg/L, (53.2 ±5.3) and (44.6 ±7.4) ng/L, (43.3 ±11.0) and (29.1 ±8.6)ng/L, (354.3 ±105.9) and (251.0 ±37.3)ng/L, all P<005].The length of hospital stay [(11.0 ±2.2) d], rate of lung infections (6/52) and neurological abnormality (3/52) in trial group were significantly lower than those in control group [(15.5 ±1.8) d, 15/54 and 11/54, all P <0.05].The expression of CD4 +CD45 + T cells [(34.9 ±3.7)% vs.(42.5 ±4.3)%] was reduced and CD4 +Foxp3 +T cells [(19.7 ±3.8)% vs.(6.9 ± 1.5)%] was increased at 24 h after surgery in trial group compared with control group( all P<0.05).The results indicates that calecoxib can reduce the inflammatory reaction by promoting CD4 + to Foxp3 + CD4+T cell differentiation and may improve the prognosis of elderly patients with hip fracture.

Objective To investigate the effects of different angles of the head of bed on intracranial pressure (ICP) and cerebral perfusion pressure (CPP) in patients with severe traumatic brain injury. Methods A prospective self-controlled study was used. The parameters of mean arterial pressure (MABP) and cerebral blood flow on 43 patients with STBI, were measured at 0° , 10° , 20° and 30° respectively. The changes of ICP and CPP were calculated according to the formula. Results With the angles of head of bed was up from 0° to 30° , MABP gradually reduced, (102.57 ± 8.34) mmHg (1 mmHg=0.133kPa), (100.74 ± 8.12) mmHg, (97.32 ± 7.94) mmHg, (94.82 ± 8.38) mmHg, so was ICP, which were (24.50 ± 6.29) mmHg, (22.88 ± 6.18) mmHg, (19.57 ± 6.22) mmHg, (17.32 ± 6.77) mmHg, and the difference was statistically significant(F=13.38,F=14.03,P<0.01). CPP reduced slightly, (78.03 ± 5.47) mmHg, (77.86 ± 5.50) mmHg, (77.75 ± 5.61) mmHg, (75.51 ± 5.76) mmHg, but the difference was not statistically significant(F=2.09,P>0.05). For moderate increased intracranial pressure patients (ICP< 25 mmHg), when the angles of head of bed up to 20° , ICP decreased gradually to(27.46 ± 5.20)mmHg and the difference was statistically significant (F=5.97,P <0.05), however,CPP did not change significantly, which was(77.50±5.35)mmHg (F=5.03,P>0.05). Conclusions Elevating the head to 30 °can rapidly reduce the intracranial pressure and ensure enough cerebral perfusion. It is a safe and effective treatment for the similar patients in emergency rescue and nursing. At the same time, for the patients with moderate intracranial hypertension (ICP ≥25 mmHg), elevation the head of bed up to 20 ° can reduce the adverse effects of intracranial pressure adaptability shortage and the cerebral hypoperfusion, increase the safety of nursing care, and reduce the secondary brain injuries.

Objective To understand medical students on the awareness level, attitude , behavior and requirement of professional bilingual teaching, so as to provide reference for bilingual teaching. Methods A self- administered was conducted among medical students from different speciality. Results There was a significant difference in awareness level of professional bilingual teaching between nursing students and clinical medicine students (χ2=4.95, P<0.05). Majority students (81.3%) supported carring out bilingual teaching. Teachers and students' foreign language level, selection of bilingual textbook, teaching mode and environment of bilingual teaching are the main influencing factors on earring out professional bilingual teaching. Conclusion Professional bilingual teaching should be implemented designedly, selectively and systematically according to practice condition of different speciality and different subject.

Medical students should study and enlarge their medical terminology from their medical English courses as well as bilingual courses. This ability is a key part in the cultivation of high-levelled medical talents.However,medical words are special from general English in three parts:long,great in numbers and difficult to read.These characteristics leave the medical students in a hard situation in their promotion of medical terminology.If the students are provided and guided with a convenient and efficient software based on modem education technology,they can achieve much better results.The audio medical English terminology corpus can help the medical students achieve their goal in promotion of medical termi-nology.
