The compound excipient containing sodium stearyl fumarate and plasdone S-630 was prepared by applying spray drying method. The basic physical properties of compound excipient were studied by solubility test, scanning electron microscope, differential scanning calorimeter, X-ray diffraction and Fourier transform infra-red spectroscopy. The effect of compound excipient on moisture absorption and ferulic acid in vitro dissolution of spray drying power of angelica were investigated. The results showed that the chemical constituents of compound excipient did not change before and after spray drying. The water soluble compound excipient can improve significantly moisture absorption and has application prospect.

ObjectiveTo study the effects on hemodynamics of portal venous system of splenorenal shunt plus pericardia devascularization (SRS+PCDV), and evaluate the clinical significance of this operative procedure.MethodsThe hemodynamic parameters of portal venous system by Doppler color-flow imaging (DCFI) of 99 patients with portal hypertension (PH) were measured before and after operation.Results(1)In SRS group the postoperative portal venous flow (PVF), free portal pressure(FPP) decreased by (57?9)%, (52?5)% respectively (P0.05).(3)In SRS+PCDV group PVF,FPP decreased by (36?8)%, (34?10)% respectively(P

Objective:Tumor common antigen of an extract of plant and applying in early stage diagnosis for tumor were studied.Methods:Tumor cells and lymphocytes proliferate responses were determined by 3H-TdR intervening.Fresh tumor tissue from human transplant to mice,the survival rate of transplanted tumor was observed.DNA content of tumor cells was measured by flowcytometery.The chemical nature was analyzed by chromatography and measured by ultraviolet-spectrometer.Results:The extract of plant markedly stimulated the lymphocytes from tumor patients and atypical hyperplasia patient to proliferate,but failed to health persons(P

AIM: To study extraction process with the aid of cyclodextrin (EPAC) of Radix Salvias Miltiorrhizae. METHODS: Taking tanshinone Ⅱ_A, Danshensu, dry extract as the indexes, EPAC and water extraction process(WEP) were compared. RESULTS:The index of tanshinone Ⅱ_A of EPAC was better than WEP in extract, but there was not obvious difference in the indexes of Danshensu and dry extract. CONCLUSION:EPAC is worth researching further.

To investigate the rat intestinal absorption of stearic acid-octaarginine (SA-R8) modified solid lipid nanoparticles containing paclitaxel (SA-R8-PTX-SLN), compared with the commercially available preparation of PTX (Taxol) and PTX-loaded solid lipid nanoparticles (PTX-SLN), the in situ intestinal absorption of SA-R8-PTX-SLN was investigated by means of single-pass rat intestinal perfusion technique. The absorptions of the preparations were investigated at different intestinal segments, different drug concentrations and in the presence of P-glycoprotein inhibitor (verapamil). The results showed that PTX could be absorbed at each intestinal segment and the three preparations all showed maximum absorptions at the duodenum. The cumulative absorptions of three preparations at each intestinal segment appeared SA-R8-PTX-SLN > PTX-SLN > Taxol (P < 0.05). SA-R8-PTX-SLN showed a liner absorption manner at the duodenum in the examined drug concentration range. The cumulative absorptions of Taxol and PTX-SLN were significantly promoted after the addition of P-glycoprotein inhibitor (verapamil) into the preparation (P < 0.05), but absorption of SA-R8-PTX-SLN existed no significantly difference compared with the preparation without verapamil (P > 0.05). SA-R8 and SLN might both effectively improve the oral absorption of PTX in the intestinal tract.

Objective:To investigate the recent and long-term efficacy and safety of pancreaticoduodenectomy for pancreatic head carcinoma and periampullary carcinoma.Methods:82 cases of pancreatic cancer combined with periampullary carcinoma patients admit ted in our hospital from August 2009 to June 2013 were selected and randomly divided into the control group and the observation group With 41 patients in each group.The control group received palliative surgical treatment,while the observation group underwent pancreatoduodenectomy.The operation time,hospitalization time,intraoperative bleeding volume and the incidence of complications,1,2,3-year survival rate and the recurrence rate at 1 year after operation and tumor eradication rate were compared between twp groups.Results:The amount of bleeding,operation time of observation group were significantly higher than those of the control group(P＜0.01),no signif icant difference was found in the hospitalization time between the two groups(P＞0.05);the incidence of complications in the observation group (41.46％) was significantly higher than the control group (22.96％)(P=0.03);the 2-year and 3-year survival rate of observation group were significantly higher than those of the control group (P＜0.05),the recurrence rate at 1 year after operation of observation group was significantly lower than that of the control group (P=0.04),the tumor eradication rate was significantly higher in the observation group than that of the control group (P=0.04).Conclusion:Though pancreaticoduodenectomy could prolong the operation time,increase the risk of bleeding and complications for pancreatic head carcinoma and periampullary carcinoma,but it could effectively reduce the possibility of recurrence after operation,significantly improve the long-term survival rate.

Objective To investigate the effects of prostaglandin E1 (PGE1) on the levels of myocardium nuclear factor‐κB (NF‐κB) and plasma tumor necrosis factor‐α (TNF‐α) in patients underwent heart valve replacement .Methods Forty ASA Ⅱ orⅢ degree patients (NYHA Ⅱ or Ⅲ degree) ,aged 32 to 67 years with body mass index of 17 to 28 kg/m2 ,underwent heart valve replacement ,were randomly divided into 2 groups (n=20):control group (group C) and PGE1 group (group P) .After induction of anesthesia ,PGE1 20 ng · kg -1 · min-1 was infused intravenously in group P ,while the equivalent volume of normal saline was giv‐en in group C ,and the infusion was completed at the end of operation .Arterial blood samples were collected at the time of before cardiopulmonary bypass (T0 ,baseline) ,30 min after the begin of cardiopulmonary bypass (T1 ) ,the end of cardiopulmonary bypass (T2 ) ,and 12 h(T3 ) ,24 h(T4 ) after the end of cardiopulmonary bypass .Myocardial specimens were obtained from right auricular appendage at T0 and T2 for microscopic examination and determination the activity of NF‐κB .Results The plasma mass concentra‐tions of TNF‐αwas significantly lower (P<0 .05) at T1 to T4 ,while the myocardial histopathological damage was lighter and the activity of NF‐κb significantly attenuated (P<0 .05) at T2 in group P than that in group C .Conclusion PGE1 can attenuate myo‐cardial injury in patients underwent heart valve replacement ,the mechanism is related to inhibit the activity of myocardium NF‐κB and decrease the plasma mass concentrations of TNF‐α.
