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.

Natural product resveratrol has antioxidation, cardiovascular protection and many other useful biological activities. In recent years, many researchers have paid more and more attention to it. However it cannot be used as candidate for the development of new drug due to its poor druggability. Novel resveratrol derivates with improved water solubility and highly potent biological activity could be obtained by chemical modifying of chemical structure of resveratrol. Researches have shown that resveratrol derivatives exhibit many kinds of attractive activities, including antitumor, reducing blood fat, antiviral, anti-neurodegenerative diseases and so on, which makes them could be used as leads for the further developing of new drugs. This review discusses the development of novel resveratrol derivatives by chemical modification in recent years.

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.

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 .

ObjectiveTo observe the therapeutic efficacy ofacupoint thread embedding in treating hyperlipidemia, and to explore a treatment method with valid efficacy and few side effects.MethodSixty patients with hyperlipidemia were randomized into a thread embedding group and a medication group, 30 cases ineach group. The thread embedding group was intervened by thread embedding at Zhongwan (CV12), Tianshu (ST25), Fenglong (ST40), and Zusanli (ST36), once a week; the medication group was by taking Xue Zhi Kang capsules, two capsules each time, twice a day. The two groups both received treatment for 8 weeks. The clinical efficacy, total cholesterol (Chol), and triglyceride levels were observed before and after treatment.ResultThe total effective rate was 86.7% in the thread embedding group versus 83.3% in the medication group, and the difference was statistically insignificant (P>0.05). After 4-week treatment, the transaminase level increased in 3.3% of the patients in the medication group, while no one showed an increased transaminase level in the thread embedding group. After 8-week treatment, the observed indexes were increased in the medication group, while those in the thread embedding group were still stable.ConclusionAcupoint thread embedding is effective in treating hyperlipidemia, and the effect is durable with few side effects.

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.
