Objective To increase the radical resection rate and decrease local-regional relapse rate in thoracic esophageal carcinoma. Methods One-hundred and four patients were prospectively randomized to receive esophagectomy with thoraco-abdominal 2-field lymphadenectomy (48 cases) or with lymph node sampling (56 cases). In 101 patients who survived after surgery, 29 received adjuvant chemotherapy with cisplatin and fluorouracil (FP). Results Comparing with lymph node sampling, the operation time for lymphadenectomy was prolonged. However, there was no increase in blood loss, surgical morbidity, or mortality. Mean stations of lymph node dissected (10.5 stations vs. 3.2 stations,P

Objective To investigate the effects of ?-asarone,the major constituent of Acorus tarinowii schott,on the expression of endothelial cell adhesion molecules induced by hypoxia and reoxygenation.Methods The expression rates of endothelial cell surface adhesion molecules VCAM-1 and CD62E were detected by flow cytometry(FCM) and specific labeled monoclonal antibody.Results Compared to the normal group,the expression rates of VCAM-1 and CD62E were increased significantly in the model group(hypoxia-reoxygenation group)(P

To establish a new method for simultaneously determining the content of five gingerol compounds in different processing degrees of ginger charcoal and PCA principal component analysis was conducted for analysis. Samples were analyzed on Ultimate TM XB-C18 column (4.6 mm x 250 mm, 5 μm) , with acetonitrile (A) -0.1% phosphoric acid solution (B) as mobile phase for gradient elution. Detection wavelength was set at 280 nm. The flow rate was 0.6 mL x min(-1) and the column temperature was 30 degrees C. The five compounds were separated well and showed good linearity (r ≥ 0.999 7) within the concentration ranges tested. The average value for recoveries was between 98.86% - 101.5% (RSD 1.4% - 2.9%). The contents of five compounds showed difference among different processing degrees of ginger charcoal. Zingiberone had the highest content in the standard carbon, and the content of gingerol was decreased as the deepening of processing degree. Different processing degrees of ginger charcoal were classified into three groups with PCA, and provided scientific basis for establishing the quality standards of ginger charcoal.

This study is to develop a sensitive method by using reversed-phase high performance liquid chromatography coupled with UV detector (HPLC-UV) to simultaneously determine four bioactive compounds, iriflophenone 3-C-beta-D-glucoside, iriflophenone 3,5-C-beta-D-diglucoside, mangiferin, and iriflophenone 2-O-alpha-L-rhamnoside in the leaves of Aquilaria sinensis. An Agilent Zorbax SB-C, column (4, 6 mm x 250 mm, 5 microm) was used, and the gradient elution was performed with mobile phase of 0.1% aqueous phosphoric acid and acetonitrile at a flow rate of 1 mL x min(-1). The detection wavelength was 280 nm, and the column temperature was 25 degrees C. The four marker compounds were well separated with good linearity (R2 > 0.9990), precision, stability and repeatabili y. The-recovery rates were in the range of 98.80%-101.39%. For 15 branch of the leaves, the contents of iriflophenone 3-C-beta-D-gluoside, iriflophenone 3,5-C-beta-D-diglucoside, mangiferin, and iriflophenone 2-O-alpha-L-rhamnoside were between 0.41-14.48, 0.72-3.85, 4.30-29.07, 0.24-5.06 mg, respectivley. This method is precise, accurate and reliable, which provides an efficient way for the quality control of the leaves of A. sinensis. This will promote the comprehensive usage of this plant.

Objective To observe the protective effect of?-asarone,the active components from Rhizoma Acori Tarinowii,on human umbilical venous endothelial cell strain ECV304 injury induced by oxidized low-density lipoprotein(ox-LDL)and to investigate its influence on proliferation of vascular smooth muscle cells(VSMC). Methods The well-grown ECV304 cells were randomized into 5 groups:normal group,control group,high-, middle-and low-dose?-asarone groups.Except the normal group,ECV in the other groups were co-cultured with ox-LDL 25?g/mL,and the?-asarone groups were additionally with?-asarone 30,15 and 7.5?g/mL added respectively.Flow cytometry was used to detect the cell apoptotic rate and the mitochondrial membrane potential (MMP)of ECV304 as well as the proliferation index and the DNA content in different cell phases of VSMC. Results In the model group,the apoptotic rate of ECV was increased,MMP was decreased,and VSMC proliferation was promoted(P

To investigate the therapeutic effects and associated complications of allogeneic peripheral blood stem cell transplantation (allo-PBSCT). 40 patients with various malignant hematopoietic diseases received allo-PBSCT. The preparative regimens were based on BUCY2 or modified BUCY2. The acute graft-versus host disease (aGVHD) was prevented by cyclosporin A and short-term MTX regimen in all patients. Two patients from donors with one fully mismatched HLA on DRB1 locus and 4 from unrelated donor also administered Zenapox (CD25 MAb) at dosage of 1 mg/kg every day on the day before transplantation and day 4 after transplantation. These 6 patients were also treated with mycophenolate mofetil (MMF). Transfusion of the donor cells: The median of the transfused nucleated cells was 5.38 x 10(8)/kg and that of the CD34+ cells was 7.8 x 10(6)/kg respectively. All the patients gained hematopoietic reconstruction except one who died of infection before engraftment. Seven patients got II degrees-IV degrees aGVHI) and the incidence was 17.5%. Fourteen patients got cGVHD and the incidence was 53.8% in the patients who survived over 6 months. Twenty-eight patients had fever or other characteristics of infection. The median follow-up time was 13.8 months. The incidence of transplantation related mortality (TRM) was 17.5% and 2 patients relapsed (5.0%). It was concluded that allo-PBSCT can reconstruct hematopoiesis quickly and is a favorable therapeutic method for leukemia.
