After the problems in military postgraduate information literacy education were analyzed, the construction of a systematic and coherent information literacy education course system for military postgraduates in close combination with their subjects was proposed by setting up multidimensional education target, designing three-stage foundation-subject-innovation course, combining traditional literature retrieval course and embedded professional course, combining case teaching, heuristic discussion and innovative talent information literacy training approach, by infiltrating the physical and virtual space both in and outside university, and by participating in the study and research activities of postgraduates.

Data management service abroad provided by subject librarians in biomedical field for scientific researchers, and the model, contents and efficiency of subject librarians-provided biomedical research data management service in NIH were analyzed according to the need for scientific research data management service in biomedical researchers . The enlightenments of biomedical research data management service abroad on the subject service in our library were elaborated .

A new method based on high performance liquid chromatography-electrospray ionization time of flight-mass spectrometry (HPLC-ESI-TOF/MS) was developed for the rapid identification of active compounds in Styela clava and the development of its specific chromatograms. Samples were extracted by ultrasonic-assisted extraction, and the extraction conditions were optimized. The developed HPLC-ESI-TOF/MS method was used to identify the components in Styela clava extract, and a specific chromatogram based on HPLC analysis was established. Ten compounds in Styela clava extract have been primary identified by HPLC-ESI-TOF/MS on-line detection combined with literature review. The result of similarity evaluation for specific chromatograms indicated that the quality of different Styela clava samples was not entirely consistent. This method has the advantages of simple operation, rapid measurement and it is a powerful tool for identification of active components in Styela clava and its quality control.

The Libguides subject service platform that integrates technologies, resources and service has effectively promoted the subject service in library.Its introduction, construction and achievements in Medical Library of Chinese PLA were described with strategies proposed for improving its problems.

The information was obtained through the open access channels and organized with free markers.The relations in research and development institutions of foreign military medical equipments were determined by analy-zing thecompetitive opponents .The information platform for research and development institutions of foreign mili-tarymedical equipments was constructed using the MVC design model in combination with Web2.0 technology and community concept of resources according to the B/S structure forthe collection, storage, organization, analysis, sharing and evaluation of military medical information resources .

Syndromic surveillance , based on non-specific pre-diagnosis and other information , is capable of nearly real-time detection and early warning of potential bioterrorism and emerging infectious threats .Developed countries , led by the U.S., have conducted in-depth and front research in this area while China has just started syndromic surveillance re -search in the exploratory trial stage .The Chinese army is facing an urgent need for syndromic surveillance .This paper makes a case study of foreign military syndromic surveillance practices , typically the U.S.representative system ESSENSE , which was developed by the U .S.Department of Defense and deployed in all military treatment facilities .Some suggestions for the Chinese army are also discussed .

The practical experiences with subject service in Medical Library of Chinese PLA were summarized in terms of the establishment of user information records, accumulation and summation of information, and construc-tion of information platform. Suggestions were put forward for the improvement of subject service in Medical Library of Chinese PLA, such as holding the big information concept in the big data era, using the biomedical data as the target of study, providing various kinds of service, integrating seamless, dynamic and interactive library service into user service. The fact that focus on artificial intelligence, computer, information and coomunication technologies is one of the future directions was pointed out.

OBJECTIVE:To provide references for clinicians in the choice of antihypertensive drugs.METHODS:The antihypertensive efficacy 6 classes(or 15 kinds) of antihypertensive drugs in a monotherapy in the treatment of 370 patients with essential hypertension(EH) were compared.RESULTS:The blood pressure was effectively lowered by all of the antihypertensive drugs except doxazosin,and doxazosin and torasemide showed inferior efficacy in the reduction of diastolic blood pressure(DBP).CONCLUSION:Calcium antagonists with prolonged action,angiotensin converting enzyme inhibitor(ACEI),angiotens-in receptor antagonist,and the monotherapy of Terazosin or Indapamide can all effectively bring down the blood pressure.It is suggested that low-dose doxazosin and torasemide should not be used alone in treating essential hypertension.

OBJECTIVETo conduct an experimental study on in vitro transdermal absorption of prepared Shangshi Zhitong cataplasm.

METHODFranz diffusing cells and mice were adopted for the percutaneous penetration study. The accumulative percutaneous permeation of total alkaloids, strychnine and atropine in certain time was determined by acid dye colorimetry and HPLC.

RESULTThe accumulative permeation of alkaloids (Q) increased with time (t), with a linear relation between them.

CONCLUSIONThe in vitro percutaneous penetration of Shangshi Zhitong cataplasm complies with the zero-order kinetics.

Objective:The aims of the study were to investigate the relationship among atherogenic index of plasma (AIP) and inflammatory adipocytokines with the severity of coronary artery calcification (CAC) score in coronary artery disease (CAD). And then we analyzed the diagnostic value of the new markers on CAC.Methods:A total of 241 patients with CAD diagnosed by coronary CT angiography (CTA) and coronary angiography in Baoding First Central Hospital from June 2019 to June 2020 were retrospectively enrolled. According to the presence of calcification in coronary CTA, they were divided into CAC group ( n=63) and non-CAC group ( n=178). The clinical data of the patients were collected, and the levels of serum inflammatory factors were measured by enzyme-linked immunosorbent assay (ELISA). The correlation between CAC score and AIP and inflammatory cytokines was analyzed. The diagnostic value of AIP and inflammatory factors in the formation of CAC in patients with CAD. Results:The levels of AIP, serum osteoprotegerin (OPG) and oligomeric matrix protein (COMP) in CAC group were higher than those in non-CAC group, while the levels of serum fibroblast growth factor 21 (FGF21) were lower than those in non-CAC group, with statistically significant difference (all P<0.01). Correlation analysis showed that CAC score of CAD patients was positively correlated with AIP, OPG and COMP ( r=0.581, 0.451, 0.326, P<0.05), and negatively correlated with FGF21 ( r=-0.294, P<0.05). Receiver operating characteristic (ROC) curve analysis showed that AIP, OPG, COMP and FGF21 had diagnostic value for CAC in CAD patients (all P<0.05). AIP>0.387, OPG>5.150 ng/ml, FGF21>136.35 pg/ml, COMP>733.16 ng/ml were independent factors affecting the formation of CAC (all P<0.05). Conclusions:The increase of AIP and the change of inflammatory factors can be used as markers for the diagnosis of CAC formation in CAD patients.
