Scientific research management is an important part of hospital management and also embodied the important aspect of the overall strength of hospital.In order to further improve the No.1 Affiliated Hospital of Hebei North University scientific research management ability,this paper uses SWOT analysis method to analyze the internal and external environment,and concluded strengths,weaknesses,opportunities and challenges in scientific research management.By using SWOT analysis strategy,we proposes corresponding countermeasures toimprove hospital scientific research management level.

At present, there is no specific antidote for local anesthetic toxicity, which seriously hindered therapeutic efficts of clinical treatment. It is increasingly urgent for finding find the effective antidote to local anesthetic. This article at-tempts to interpret the molecular pharmacological mechanism from fat pool, energy metabolism, NO, ion channel and solubili-zation for the role of fatty acids in reversal of myocardial toxicity of local anesthetics. And the different characteristics of the structure and function of nano liposome and fat emulsion were compared.

Evaluation of regional health service system can provide guidance for regional health planning,improve the ability of the national macro-control and supervision,and optimize the medical resource allocation.China has yet to establish a set of scientific and comprehensive evaluation index system.Through the introduction of the importance,influence factors and the current methods in evaluation of regional medical service system in US,suggestions are provided for establishing and improving China's evaluation system of regional health service.

Objective To explore the value of adenosine deaminase (ADA),interferon (IFN)-γand soluble interleukin-2 receptor (sIL-2R) in differential diagnosis of tuberculous and malignant pleural effusion.Method The ADA activity,IFN-γ and sIL-2R levels of 48 patients with tuberculous pleural effusions and 32 patients with malignant pleural effusion were measured by colorimetry and ELISA respectively.Results The ADA activity,IFN-γand sIL-2R level in tuberculous pleural effusion was higher than that in malignant pleural effusion (P < 0.05).According to the receiver operator characteristic (ROC) curve,when 45 U/L was regarded as critical value of ADA,the sensitivity,specificity and accuracy of ADA in diagnosing tuberculous pleural effusion was 82%,91% and 86% ; when 100 ng/L was regarded as critical value of IFN-7,it was 85%,94% and 89%; when 450 μg/L was regarded as critical value of sIL-2R,it was84%,81% and 83%.When combined detection of three targets was done.it was 88%,100% and 94%.Conclusion The combined detection of ADA,IFN-γand sIL-2R can improve sensitivity,specificity and accuracy in diagnosing tuberculous pleurisy.

Corticotropin-releasing factor(CRF)is one neuroendocrine peptide which is closely related with the stress.It has been proved that any stress can lead to the person and animal's blood CRF level increasing,and high-level CRF urges the hypothalamic neuron calcium ion inflow.Newborn pediatricians pay more attention to whether blood CRF level can act as one director of assessing severity of newborn hypoxic-schemic brain damage.This article reviews the CRF and it's acceptors,CRF secretion,CRF physiological action and it's adjustment,and hypoxia-ischemia stress and CRF,in order to provide the theory basis for reviewing the severity of hypoxic-schemic brain damage in neonates.

Objective To analyze the relationship between atrial fibrillation (AF) and plasma mononuclear cells or cardiac func-tion .Methods From April 2010 to Jun 2013 ,298 patients with AF from department of cardiology in our hospital were selected as study group ,300 patients without AF were selected as control group in the same period .Both group and the subgroup were analy-sised by t test .Results Plasma monocyte NT-proBNP ,left atrial diameter in AF group were significantly higher than the control group(P<0 .05) ,LVEF was lower than the control group ,the statistical differences between the two groups (P<0 .05) .Compare HF combine AF with HF only ,the NT-proBNP and left atrial diameter were significantly higher in former and the LVEF is lower than the latter ,both with the difference statistical significantly (P< 0 .05) .Merge heart failure combined with atrial fibrillation (HF+AF) and heart failure combined sinus rhythm (HF+ SR) group ,the former in the NT-proBNP and left atrial diameterwere significantly higher than the latter ,LVEF lower than the latter ,the difference was statistically difference (P<0 .05) .Conclusion In the development of AF ,the monocytes may be involved in the occurrence and development of AF .

Objective:To investigate the protection mechanism of rosavin in learning and memory ability in subacute aged rats in-duced by D-galactose. Methods:Totally 48 SD rats were randomly divided into the normal group, model group, positive drug group, and rosavin group respectively at the dose of 6, 12 and 24 mg·g-1 . Except the normal group, the other rats were with neck subcuta-neous injection of D-galactose 120 mg · kg-1 · d-1 . After 4-week drug administration, the learning and memory ability of rats was studied using Morris water maze. PO2 , SaO2 , the activity of superoxide dismutase ( SOD) , catalase( CAT) and glutathione peroxidase ( GSH-Px) and the content of O2 and malonaldehyde( MDA) of rats in vivo were determined at the end of the experiment. Results:The aged rats treated with rosavin(12 or 24 mg·kg-1·d-1) were with significant shortened latent period in Morris water maze(P<0. 01 or P<0. 05), and with reduced total swimming distance and error angle. Meanwhile, rosavin(6,12 or 24 mg·kg-1·d-1) could im-prove the concentration of O2 ,PO2 and SaO2 , the activity of SOD, CAT and GSH-Px in brain, while decrease the content of MDA with certain dose-effect relationship. Conclusion:Rosavin can inhibit D-galactose induced learning and memory decrease in rats, and the effect may be related with the increase of oxygen content, enzyme activity protection of SOD, CAT, MAO and GSH-Px and decrease of MDA generation.
