Objective To recommend the appropriate retrieval tools for scientific researchers and improve their re-trieval efficiency by comparatively analyzing the retrieval results from PubMed and Embase .com.Methods Eight retrieval terms from different subjects were used to retrieve PubMed and Embase .com by subject headings and basic retrieval methods than can automatically transfer their function .Results Six different results were retrieved from PubMed and Embase.com with 8 retrieval terms.Conclusion The recall ratio is higher in Embase.com than in PubMed when they are retrieved by subject headings while the accuracy ratio is higher in PubMed than in Embase . com when they are retrieved by basic retrieval methods than can automatically transfer their function although error transformation occurs in both PubMed and Embase.com.

Objective To understand the learning needs of nursing students for nursing English in senior high vocational school.Methods A survey was carried out among 982 three-year nursing students in grade 2007-2009 in Cangzhou medical college by questionnaire.The data collected were analyzed using descriptive statistics with SPSS 17.0.Results Most students (93.0％) believed that nursing English was important and had a strong desire for most English skills,especially speaking and listening ability.They (90.7％) expected nursing teachers to take charge of or participate in teaching work and some students (30.6％) were dissatisfied with teaching material.They depended on teachers' instruction and preferred learning in real situations.Conclusions Nursing students in senior high vocational school have strong needs for nursing English,but there is a gap between current teaching situation and learning needs,which the course designers and teachers should take into full consideration in order to make the teaching more effective.

With the development of clinical pharmacy in hospital,the demand for pharmacy intravenous admixture services (PIVAS) has been gradually increased.By being built inside the pharmacies,PIVAS of this hospital has created a full range of integrated pharmacy service platform.With independent research and development of information management system,innovative design of the modules and equipments based on the concept of internet of things,and integration of artificial and computerized checking,PIVAS of this hospital has formed a system of prevention and control chain,it has been deepening the connotation of clinical pharmacy services,and providing higher quality pharmacy services to clinical drug using.

Reference service is one of the key tasks in library.The current situation of reference service in library and its problems were analyzed from the need of readers, and the problems to which attention should be paid were pointed out from its convenience and time-effectiveness .

Viral myocarditis can cause severe myocardial injury and even acute heart failure, then evolve into dilated cardiomyopathy, known as inflammatory cardiomyopathy. Immune reaction plays a key role in the transformation from viral myocarditis into dilated cardiomyopathy, including virus RNA continuous replication,immune-mediated injury, cellular apoptosis, other cellular immune response , myocardial antibodies and other humoral immune response. In the clinical treatment, besides anti-heart failure and cardiac nutrition, the use of ribavirin, α1-receptor blockers, β-receptor blockers, calcium channel blockers, angiotensin converting enzyme inhibitors and spironolactone should be emphasized.

Thirty-four patients with chronic lingual tonsillar hypertrophy were treated in our department from 1994 to 2000. There were 18 males and 16 females ranging in age from 21 to 60 years old. The clinical feature of lingual tonsillar hypertrophy usually appeared a series of pharyngeal symptoms, such as foreign-body sensation, sore throat, speech change, difficulty in swallowing, dysapnea and obstructive sleep apnea. The CO2 laser surgical lingual tonsillectomy was used for these patients. Result showed that the cure rate was 100% without any serious complications by following up 2 months to 3 years. The variety of presentations of lingual tonsillar hypertrophy and methods of surgical treament were discussed.

The reactivity of vascular smooh muscle cell (VSMC) of coronary artery ofguinea pig fed with grains from Keshan disease area were studied by intracellular microelec-trode method. The glass micropipette of tip resistance 30-50 M? filled with 3 M KCl wasinserted from the inner surface of the vasclar segment. The resting membrane potential (Em)of VSMC of coronary artery was observed. The results were as follows: (1) Em ofVSMC of experimental group was -49.80?5.3mV. (2) The Se induced VSMC depolari-zation revealed a dose-response dependent manner in the experimental animal. The degreeof the depolarization was smaller than those in the control guinea pig. (3) KCl and AChcaused membrane depolarization and hyperpolarization respectively in the experimental group,but the changes of Em was higher than those in the control. From these facts it wasconcluded that the reactivity of coronary artery VSMC was increased in experimentalgroup. It was suggested that the vessel's factor play an important role in the pathogenesisof myocardial necrosis in experimental group animal.

Objective To establish the reference intervals of thyroid hormone levels fro the women in early ,middle and late preg‐nancy in the local area .Methods Through the strict screening for routine diagnosis of pregnant women who went to the hospital , we choose 420 women with 6-37 weeks of pregnancy and 120 non pregnancy women(control group) .Chemiluminescence was used to detect thyroid stimulating hormone(TSH) ,free thyroxine(FT4 ) ,total thyroxine(TT4 ) ,free triiodothyronine(FT3) ,total triiodo‐thyronine(TT3 ) for the pregnant women in early pregnancy(0-12 weeks) ,mid‐pregnancy(13-27 weeks) ,and late pregnancy(28-40 weeks) and women in control group .Using those data ,we established reference intervals of thyroid hormone and use bilateral limits P2 .5 - P97 .5 to represent .Results The differences of serum TSH ,FT4 ,TT4 ,TT3 concentration between pregnant group and control group were statistically significant(P<0 .05);while the difference of serum FT3 concentration between pregnant group and control group was not statistically significant(P=0 .79) .The concentration of TSH was not statistically significantly different in the mid‐pregnancy compared with late pregnancy(P=0 .933) ,the reference interval can be merged as 0 .56-3 .94μIU/mL .Conclu‐sion The establishment of normal reference interval of thyroid hormone concentration in different period of pregnancy respectively is conducive to the diagnosis and treatment of thyroid disease in pregnancy .
