Objective To establish the method for detemining the content of chlorogenic acid in Shuanghuanglian Keli by HPLC.Methods Using Diamonsil ODS1 C18 column,with methanol-water-glacial acetic acid(15:85:1) as the mobile phase,detection wavelength as 324 nm and flow rate was 1.0 mL/min.Results The calibration curve was linear at the range of 0.060～1.210 ?g for chlorogenic acid and the equation was Y=105 427X+586.43,r2=0.999 5.The average recovery was 99.3% and RSD was 0.82%(n=6).Conclusion This method was simple,accurate and proper,and the reduplication of the result was good,which provide scientific quantitative analysis method of chlorogenic acid in Shuanghuanglian Keli.

Objective To evaluate of red blood cell as giving instruction in whole white blood cell immunological activity by new nature experimental system of hemaimmune reaction rood map. Methods Plasma 0.3ml were added to whole blood cells (including: red blood cell and white blood cells) or white blood cells 0.2ml, and incubated for 1h at 37℃. The content of IL-8 and IL-12 was determined by enzyme linked immunadsorbent assay (ELISA) method. The expression level of CD4, CD8, CD35 and CXCR4 on white blood cells was determined by method of Flow Cytometry. Results The content of IL-8 (5.96?4.26) and IL-12 (9.84?2.23) in whole blood and plasma nature group was significantly lower than that (13.59?3.69?B?pg~ -1 ?ml~ -1 ) and (15.09?9.86?B?pg~ -1 ?ml~ -1 ) in white blood cell and plasma isolation group (P

Objective:To summarize and analyze the clinical status of tumor necrosis factor-α (TNF-α) antagonists.Methods: The clinical trials of TNF-α antagonists registered before August 2,2016 were searched on the National Institutes of Health (NIH) Clinical Trials Register,and SPSS17.0 software was used for statistical analysis of the data.Results: A total of 306 TNF clinical trials were conducted in the world,19 of them were in China.The main research diseases for bone and joint disease,autoimmune diseases,infections,blood tumors.There were 241 items in intervention study,and 56,7,55,60 items in 178 cases,accounting for 73.9% in Ⅱ,Ⅱ/Ⅲ,Ⅲ,Ⅳ,respectively.The interventional study of TNF-α antagonist clinical trials mainly focused on intervention research,The main purpose of the practical application of the process after the listing of further validation and evaluation of drug efficacy and safety.Conclusion: There are many kinds of TNF-α antagonists,and clinical indications are wide.The design of clinical trials is diversified and mature.

Objective To evaluate the accuracy of remifentanil target-controlled infusion (TCI) system in children.Methods Thirty ASA Ⅰ patients (aged 3-12 years and weighing 10-40 kg) scheduled for elective ear-nose-throat or urological surgery were randomly divided into two groups (n =15 each):2 ng/ml remifentanil group (group Ⅰ) and 4 ng/ml remifentanil group (group Ⅱ).Anesthesia was induced with intravenous injection of propofol 2 mg/kg and TCI of remifentanil.Remifentanil was administered with a specific TCI system incorporating the pharmacokinetic parameters of Minto.The target plasma concentration of remifentanil was set at 2 or 4 ng/ml.Tracheal intubation was facilitated with vecuronium 0.1 mg/kg after the children lost consciousness.The children were mechanically ventilated.Anesthesia was maintained with TCI of remifentanil,intravenous infusion of propofol and intermittent intravenous injection of boluses of vecuronium.The target plasma concentration of remifentanil remained unchanged and bispectraI index value was maintained at 45-65 or auditory evoked potentials index value ＜ 30 through adjusting the infusion rate of propofol.Arterial blood samples were taken at 5,10,20,30,40,50 and 60 minutes after TCI of remifentanil was started for determination of blood remifentanil concentrations by high performance liquid chromatography.Median prediction performance error (MDPE),median absolute performance error (MDAPE) and wobble of remifentanil TCI system were calculated.Results The measured concentrations of remifentanil were significantly higher than the target plasma concentrations jn both groups (P ＜ 0.05).The MDPE,MDAPE and wobble were 20.0％,30.0％ and 25.0％ respectively in group Ⅰ,and 17.5％,17.5％ and 12.5％ respectively in group Ⅱ.The MDAPE and wobble were significantly decreased in group Ⅱ compared with group Ⅰ (P ＜ 0.05).Conclusion When remifentanil is administered using a specific TCI system incorporating the pharmacokinetic parameters of Minto in children of 3-12 years old,the accuracy is not high.

Objective To assess the application value of real time three-dimensional (RT-3D) ultrasonography in diagnosis of fetal corrected transposition of the great arties (cTGA). Methods Data of 14 fetuses diagnosed as cTGA clinically were reviewed. With 2D ultrasonography, diagnosis views were obtained and then studied using cardiac three-section analytic method. With real time 3D (RT-3D) ultrasonography, volume datasets were acquired at the level of four chamber view, and spatio-temporal image correlation (STIC) was then used to analyze the relationship of the two great arties. Confirmed by infant echocardiography and the autopsy findings, the accuracy of RT-3D and 2D ultrasonography in evaluation of fetal cTGA and complications were compared. Results The accuracy rate of RT-3D and 2D ultrasonography in diagnosis of fetal cTGA was 92.86% and 71.43% (χ~2=2.19, P=0.14). The procedure time of RT-3D ultrasonography was significantly shorter than that of 2D ultrasonography (t=10.23, P＜0.001). Conclusion RT-3D ultrasonography can evaluate fetal cTGA and its complications more quickly and exactly than conventional 2D ultrasonography.
