Objective To study the expression level of interleukin (IL)-22 in the peripheral blood of patients with ankylosing spondylitis and its clinical significance.Methods The mRNA level of IL-22 in the peripheral blood was measured by real-time quantitative polymerase chain reaction,and the plasma level of IL-22 was measured by enzyme linked immunosorbent assay in 30 patients with ankylosing spondylitis and 30 normal controls.Results The mRNA level of IL-22 in the peripheral blood and the plasma level of IL-22 in patients with ankylosing spondylitis were statistically higher than those in normal controls [1.82 ± 0.79 vs.1.31 ± 0.63 and (47.08 ± 17.25) ng/L vs.(30.47 ± 11.24) ng/L,P ＜ 0.05].Conclusion The level of IL-22 in the peripheral blood of patients with ankylosing spondylitis increases,and IL-22 may participate in the occurrence of ankylosing spondylitis.

OBJECTIVE: To confirm the feasibility of target-controlled infusion of midazolam on conscious sedation for patients undergoing combined spinalepidural anesthesia and the needed target-controlled blood concentration.METHODS: Sixty patients undergoing combined spinal-epidural anesthesia were subjected to target-controlled infusion of midazolam.The level of sedation of midazolam was evaluated applying OAA/S score and bispectral index(BIS).The correlation between target-controlled blood concentration(Cp) and BIS was determined.The Cp,BIS,MAP,HR and SpO2 at different OAA/S were observed. RESULTS: When OAA/S score was 3,the required target-controlled blood concentration of midazolam was(122.8? 20.8) ng? mL-1 in midazolam sedation patients.There was a good correction between BIS and Cp,and BIS=— 3.28Cp+ 355.22(r=— 0.862 5,P

Objective: To develop an HPLC method for the determination of rutin, hyperin and quercetin in Vicia sepium L. . Methods:The samples were separated on an Agilent ZORBAX Eclipse XDB-C18 column(250 mm × 4. 6 mm, 5 μm) with the mobile phase consisting of acetonitrile-1‰ phosphoric acid solution with gradient elution at the flow rate of 0. 8 ml·min-1 . The column tem-perature was 30℃, and the detection wavelength was set at 370 nm. Results: The linear range of the three components was 4. 090-130.940 μg ·ml-1(r=0.999 9), 4.600-147.200 μg ·ml-1(r=0.999 9) and 0.810-25.780 μg·ml-1(r=0.999 8), and the average recovery was 103. 45% (RSD=1. 25%), 98. 96% (RSD=1. 77%) and 102. 88% (RSD=0. 84%)(n=6), respectively. Conclusion:The method is stable, reproducible and simple, which can be used in the quality control of Vicia sepium L. .

Objective:To investigate the migration and odontogenesis of rat dental pulp cells transfected with adenovirus vector enco-ding cadherin-11.Methods:The dental pulp cells were cultured and transfected with pDC316-mCMV-EGFP-Cadherin-11.Cad-11 protein expression of the cells was examined by immunohistochemistry staining.The odontogenic differentiation of the cells was studied by alizarin red staining and ALP staining.The adhesion and migration of the cells were tested.Results:Transfection of pDC316-mC-MV-EGFP-Cadherin11 promoted Cad-11 protein expression and ALP activity,increased calcified nodule formation(P <0.05),adhe-sion and migration of rat dental pulp cells(P <0.05).Conclusion:Cadherin-11 may promote the odontoblast differentiation and mi-gration of rat dental pulp cells.

Objective To statistically analyze data of blood transfusion from General Hospital of Chengdu Military Command,Mianyang field blood station,Deyang field blood station and other military medical institutions from May 12 to June 30,2008 so as to provided certain references for reasonable blood supportability in wartime and disaster.Methods A statistical analysis was done on data of blood collection and supply including self-taken blood and assembled blood,total amount of blood supply as well as the transfusion information of inpatients injured by earthquake in our hospital.Results The amount of self-taken blood was 5 111 U,the amount of assembled blood 3 380 U and the total amount of blood supply 1 0405.5 U.But blood transfusion was 4 090.6 U in 132 patients admitted into General Hospital of Chengdu Military Command.In addition,the crest-time of transfusion appeared at 96 hours after earthquake.Moreover,patients with fractures received the highest rate of blood transfusion and crush syndrome patients received the most blood transfusion and the highest per capita transfusion.Conclusions Blood supportability in earthquake is different from that in wartime and other disasters in aspects of transfusion time,blood types and blood transfusion volume.It is important to analyze the characteristics of transfusion in patients injured by earthquake for national strategy of blood supportability in disasters and for blood supportability in the wartime.

Objective To investigate the current statues of anticoagulation therapy for ischemic stroke patients with atrial fibrillation(AF) and compared the difference with guidelines.Methods Three hundred and fifty-eight patients with cerebral infarction and atrial fibrillation in Xinhua Hospital Affiliated to Shanghai Jiaotong University from Jan.2008 to Jun.2012 were selected as our subjects.The data related to the antithrombotic therapy were collected and analyzed.Results Among patients with ischemic stroke,the rate of preexisting AF was 70.9％ (254/358),and warfarin taken rate was 4.3％ (11/254) before stroke onset.Of warfarin taken patients,INR were less than 1.5.Of all out hospitalized patients,20.9％ (68/326) were treated with warfarin therapy.There were the negative correlation between warfarin usage and HAS-BLED score,MRS score,antiplatelet drugs (OR =-1.974,-0.725,-4.170,P ＜ 0.05 or P ＜ 0.01).Among patients with warfarin usage in hospital,33.8％ of subjects (23/68) still remain on warfarin even out of hospital.The medium dosage was 2.5 mg (1.25-3.75 mg),and INR was controlled at ranged of 1.5-3.1.Periods of warfarin therapeutic range (TTR) was (61.6 ± 21.2)％.Conclusion The anticoagulation treatment rate and INR were lower in patients cerebral infarction with atrial fibrillation.Warfar might no be universal use due to the bleeding concerns and un-onvenience of monitoring INR.

Objective To compare the different expression of EBNA-1 in the normal human lymphocytes and in the EBV-induced lymphomas so as to provide the basis for studying the mechanism of the EB virus-induced lymphoma. Methods Animal model of EBV-induced lymphoma was constructed in SCID mice. EBNA-1 gene expression level was detected by real-time PCR and Western blot. Results EBV-induced lymphomas in animal model were replicated. EBNA-1 gene was expressed both in normal human lymphoma cells and 3 EBV-induced lymphoma cells. In EBV-induced lymphoma cells , the expression was up-regulated 11 683 times than in normal lymphocytes. Western blot results showed that the expression of EBNA-1 protein in induced lymphoma cells increased significantly compared with that in normal lymphocytes. Conclusions EBNA-1 expression in EBV-induced lymphoma cells is up-regulated than in normal lymphocytes. EBNA-1 may play an important role in the development of EBV-induced lymphoma.

Objective To assess the effect of simvastatin on secretion of VEGF in blood serum and sputum of elderly chronic ob-structive pulmonary disease(COPD)combined with PAH patients and the pulmonary function.Methods Seventy cases of elderly COPD patients combined with PAH patients were randomized in two groups,namely the normal treatment group and combined sim-vastatin group (35 cases in each group),then compare the changes of the VEGF in blood serum,sputum and lung function.Results VEGF in blood serum and sputum showed significant changes after therapies of simvastatin (P <0.05).After 4 weeks′therapy, the FEV1% pre and FEV1/FVC increased significantly (P <0.05).Conclusion Normal treatment combine with simvastatin could decrease VEGF in blood serum and sputum of elderly COPD combined with PAH patients,meanwhile improve pulmonary function.
