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 establish a HPLC method for content determination of paeoniflorin in refined coronary tablets.METHODS:HPLC was performed on Kromasil C18 column at room temperature,the mobile phase consisted of acetonitrile-0.2%phosphoric acid solution(13∶87),the detection wavelength was 230nm with flow rate 1ml/min and sample size 10?l.RESULTS:Paeoniflorin was linear with the peak area in the range of 0.317?g～1.587?g(r=0.9 999),the average recovery was 100.1%(RSD=1.46%).CONCLUSION:The established method is simple,reliable,reproducible and can be used for the quality control of refined coronary tablets.

Objective Early clinical symptoms of esophageal cancer are often not obvious , so a deeper insight into tumor markers is very important for the early diagnosis of esophageal cancer .This study was to investigate the expressions of Rock 2 and Wnt11 in the specific esophageal cancer cell lines Eca-109 and HEEC and the relationship of the signal transduction pathway of proteins with the development of esophageal cancer . Methods Esophageal cancer cell lines Eca-109 and HEEC were cultured and the expression levels of Rock2 and Wnt11 in the cell lines were determined by real-time quantitative PCR and Western blot . Results The mRNA expressions of Rock2 and Wnt11 were significantly increased in the Eca-109 as compared with those in the HEEC cell line (4.955± 0.539 vs 1.000±0.000, P<0.01;2.925±0.230 vs 1.000±0.000, P<0.01), and so were the protein expressions of Rock 2 and Wnt11 (955.000±21.628 vs 778.844±102.193, P<0.05;2175.316±145.623 vs 1312.233±50.734, P<0.05). Conclusion The up-regula-ted expressions of Rock 2 and Wint11 may be the markers of the metastasis of esophageal squamous cancer .

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 explore the imaging features and its correlation with pathological findings of giant cell tumor of the ten-don sheath (GCTTS).Methods The clinical data,radiographic images and pathological characteristics of sixteen cases of GCTTS confirmed by pathology were retrospectively reviewed.Plain CT,pre and post-contrast MR were performed in all patients.HE stai-ning was used to investigate the histological characteristics of GCTTS,and immunohistochemistry was employed to detect the ex-pression of CD68.Results There were nine cases of local type GCTTS and seven cases of diffuse type GCTTS in our present study. Nine cases were located in the knee joint,four cases in the foot,and three cases in the hand.Compared with normal skeletal muscle signals,lesions showed isointensity or low intensity on T1 WI and inhomogeneous low intensity on T2 WI.Three cases caused adja-cent bone destruction,one case lead to adjacent bone absorption,and no abnormality was found in other twelve cases.Six cases were injected Gd-DTPA for enhanced scan,in which four cases showed significantly heterogeneous enhancement,one case mild heteroge-neous enhancement,and one case no heterogeneous enhancement.Pathology examination results revealed that GCTTS parenchyma cells were mainly formed by histocyte-like monocytes,and scattered multinuclear giant cells.GCTTS mesenchyme was rich in gelat-inous fiber and hemosiderin pigmentation.Conclusion MR has a significant advantage in detecting specific hemosiderin pigmentation and determining lesions area of GCTTS.Combination of MR with pathology results may improve the diagnosis accuracy.
