Objective To determine the content of 5,7-dimethoxycoumarin in Fructus Citris Sarcodactylis. Methods HPLC was used. Mobile phase was methanol-water(65 ∶35),detection wavelength at 326 nm,flow rate 1mL/min and column temperature at 35 ℃.Results The linearity of 5,7-dimethoxycoumarin was in the range of 0.3528～1.7640 ?g. The regression equation was Y=2403.73 X-65.35,r=0.9998. The average recovery was 99.33 %,RSD=1.47 %(n=6). Conclusion The method is simple and accurate. It can be applied in the determination of 5,7-dimethoxycoumarin in Fructus Citris sarcodactylis.

Objective To analyze the changes of Blood Cell Count and D-dimer concentration in lung cancer patients with thrombosis.Methods ①554 cases of patients with lung cancer were included between January 2012 and November 2013,75 patients with other diseases which lead to high coagulation state were excluded,blood cell count and D-dimer concentration were compared between 64 lung cancer patients were the cases with thrombosis with 415 lung cancer patients were the con-trol group without thrombosis.②Color doppler ultrasonography was taken as the golden standard,receiver operating charac-teristic curves (ROC)were drawn for indexes which had significance in method.Results ①Compared with lung cancer pa-tients without thrombosis,lung cancer patients without thrombosis had decreased red blood cell count (RBC),increased white blood cell count (WBC)and D-dimer.And there were no significant change in platelet (PLT).②The area under curve (AUC)of ROC in RBC,WBC and D-dimer were 0.662,0.637 and 0.896,respectively.By thecut-off values of RBC>4.06× 1012 L,WBC<5.37×109/L and D-dimer<4.02 mg/L,the negative predictive values of RBC,WBC and D-dimer for diagno-sis of lung cancer patient with thrombosis were 93%,93% and 96%,respectively.By the cut-off value of D-dimer>4.02 mg/L,the positive predictive value of D-dimer for diagnosis of lung cancer patient with thrombosis was 6 6%.Conclusion RBC,WBC and D-dimer were related with the progress of thrombosis in lung cancer patients.RBC,WBC and D-dimer have good negative prediction effect on lung cancer patients with thrombosis.D-dimer had positive effect for diagnosis of lung cancer with thrombosis.

Objective: To study the chemical constituents from the fruits of Solanum virginianum. Methods: By means of preparative HPTLC and column chromatography over silica gel and Sephadex LH-20, compounds were isolated and purified. Their structures were elucidated by physico-chemical properties and spectral analyses. Results: Twelve compounds were obtained and identified as: 5-hydroxy-8-methoxy-6,7-methylenedioxyflavone (1), 7-hydroxy-6-methoxy coumarin (2), fraxetin (3), 5-hydroxy- 6,7,3',4'-tetramethoxyflavone (4), 5-hydroxy-4',6,7-trimethoxyflavone (5), dihydro-N-feruloyltyramine (6), N-trans-coumaroyltyramine (7), 5,3'-dihydroxy-6,7,4'-tritermethoxyflavone (8), N-[2-(3,4-dihydroxyphenyl)-2-hydroxyethyl]-3-(4-methoxyphenyl)-prop-2-enamide (9), N-trans-coumaroyloctopamine (10), 5,7,4'-trihydroxy-6-methoxyflavone (11), and 5,7,4'-trihydroxy-8-methoxyflavone (12). Conclusion: Compound 1 is a new flavonoid, named as solacarpumon, and compounds 2-12 are isolated from Solanum virginianum for the first time.

In 2014,serious Ebola fever epidemic broke out in West Africa .Afterwards, the US transported two Ebola patients from Liberia by air, which aroused world wide concern .During the aeromedical evacuation , there were lots of tech-nical problems and management procedures involved .First, the US government toke emergency measures for the patients in a local hospital ,which made evacuation possible .Secondly , the US CDC and other government departments coordinated this matter during and after the evacuation .Finally,upon arrival at home the two patients received careful isolation and treat-ment.Thus, the successful aeromedical evacuation is instructive for us .

The outbreak of Ebola hemorrhagic fever in West Africa in February 2014 is the worst one in the history of the disease.Medicines and vaccines for Ebola have attracted special attention .This study utilizes Cortellis database of Thom-son Reuters and knowledge about Ebola virus to analyze current R&D of medicines and vaccines for Ebola in order to offer references for research and development .Study findings shows that there are mainly 5 important categories:vaccines, neu-tralizing antibodies , small-molecule anti-Ebola drugs , RNAi drugs and nucleotide drugs .In each category , there are prom-ising products under development that are worthy of attention .

Objective Non-contrast enhanced magnetic resonance angiography ( MRA) has become the focus of research at home and abroad .The aim of the article was to optimize the scan parameters of renal artery with inflow-sensitive inversion recovery ( IF-IR) MRA. Methods 30 cases of renal artery patients into two groups were collected from December 2013 to May 2014 in our hospi-tal.They were divided into stenosis group(n=12) and non-stenosis group(n=48).IFIR-MRA sequences were carried out on each patient by using various BSP-TI with 1200,1300 and 1400 ms, all other parameters were identical .The image signal to noise ratio, a renal artery branch and venous artifact were evaluated by two experienced radiologists , and the best BSP-TI was obtained from different groups. Results BSP-TI=1400 ms was optimal for renal artery stenosis group while 1200 ms was the most suitable for non-stenosis group. Conclusion IFIR-MRA of renal artery can achieve better image quality of renal artery and its branches and it is feasible in clinical routine practice , especially for those patients with renal insufficiency .

Objective: To explore the clinical and anatomical characteristics of coronary slow lfow (CSF) in relevant patients.
Methods: We summarized the patients without coronary angiography (CAG) proved coronary stenosis (stenosis < 40%) while with TIMI indicated CSF in our hospital from 2013-01 to 2015-01. The patients were divided into 2 groups: CSF group, n=56 patients having at least 1 major coronary artery with TIMI frame counts > 27 and Control group,n=55 patients with normal coronary lfow. The related laboratory indexes were examined and relationship between MCV and CSF was studied by multi-logistic regression analysis.
Results: In CSF group, MCV 90.4 (87.48, 92.65) fL and RDW-CV 12.5 (12.30, 13.18) % were lower than those in Control group 92.3 (90.1, 94.3) fL and 13(12.7, 13.4) %,P<0.05; while MCHC 337 (332, 347) g/L and the number of left circumlfex distal braches involved 3 (2, 4) were higher than those in Control group 327.5 (322, 338) g/L and 2 (2, 3),P<0.05. Multi-logistic regression analysis showed that MCV was negatively related to CSF (partial regression coefficient= -0.138, P=0.015), Spearman rank correlation analysis presented that MCV was negatively related to TIMI frame counts (r= -0.201, P=0.009).
Conclusion: Deformability of red blood cells might be involved in pathogenesis of CSF in relevant patients.

Objective To investigate the risk factors associated with gastroparesis syndrome after laparoscopic pancreatoduodenectomy which provide reference for clinical prevention.Methods Ninety cases of laparoscopic pancreatoduodenectomy admitted from August 2013 to December 2016 in Traditional Chinese Medicine Hospital of Guangdong Province were studied retrospectively,57 were male(63.3%),the average age was 54.6 years old.Twenty cases were diagnosed postoparative gastroparesis syndrome(22.2%).To screen out the risk factors,31 independent variables were analyzed by univariate analysis and logistic regression.Results Univariate analysis showed that malnutrition,hypoproteinemia,anemia,pylorus-preserving,extensive lymph nodes dissection,anxiety,high blood sugar before operation,delay of enteral nutrition,abdominal infection and postoperative high blood sugar were associated with postoperative gastroparesis(The value of OR were 3.143,3.587,2.852,2.889,3.231,7.071,2.889,5.359,6.000,6.263,P<0.05).Multivariate Logistic regression analysis showed that extensive lymph nodes dissection,anxiety,pylorus-preserving,abdominal infection,delay of enteral nutrition,hypoproteinemia,postoperative high blood sugar were risk factors of postoperative gastroparesis(The value of OR were 17.574,8.931,6.637,6.461,6.446,5.414,5.200;P<0.05).Conclusion Multiple risk factors can lead to gastroparesis after laparoscopic pancreatoduodenectomy,measures should be taken aimed at these risk factors during perioperative period.
