Objective To explore the inhibitory effect of astragalus polysaccharide (APS) on the proliferation of human erythroleukemia K562 cells and its mechanisms.Methods After K562 cells (purchased from Shanghai cell bank of chinese academy of science) were treated with different concentrations (0 mg/L,100 mg/L,200 mg/L and 400 mg/L) of APS.The influences of APS on the growth rate,doubling time and cell cycle distribution of K562 cells were observed by methyl thiazolyl tetra-zolium assay (MTF) and flow cytometry,respectively.Furthermore,the reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting assay were used to detect the expressions of Cyclin A,Cyclin B,Cyclin E and p21 gene at the mRNA and protein levels,respectively.Results MTT assay findings showed that,compared to the control group (0 mg/L APS),growth rates of K562 cells treated with 100 mg/L,200 mg/L and 400 mg/L APS decreased significantly (all P ＜ 0.01),and the doubling times lengthened significantly (all P ＜ 0.01).Flow cytometry findings revealed that,compared to the control group,the G1 phase cells in K562 cells of APS group increased significantly (P ＜0.01),while the S and G2/M phase cells decreased significantly (all P ＜ 0.01).RT-PCR and Western blotting results indicated that Cyclin B and Cyclin E expression of K562 cells at the mRNA and protein levels in the APS group were significantly lower than those of the control group(all P ＜ 0.01),whereas p21 expression was significantly enhanced at mRNA and protein levels (P ＜ 0.01),and Cyclin A expression was not significantly different at mRNA and protein levels between the 2 groups (all P ＞ 0.05).Conclusions APS could inhibit the proliferation of human erythroleukemia K562 cells.APS could inhibit the proliferation of K562 cells by down-regulating the expression of Cyclin B and Cyclin E and up-regulating the expression of p21.

Objective To study features of clinical manifestation,pathology and treatment effects of idiopathic membranous nephropathy(IMN).Methods A retrospective study was performed in patients with membranous nephropathy through renal biopsy diagnosis in Beijing Children's Hospital Affiliated to Capital Medical University from November 2009 to February 2013.Patients were diagnosed according to renal biopsy apart from hepatitis B virus-associated glomerulonephritis,Henoch-Schonlein purpura nephritis,lupus nephritis,tumor and drug associated nephritis.The study summed the clinical and pathological features of IMN and evaluated the effect of treatment according the follow up.Results (1) There were 13 patients,with the ratio of male and female being 1.0 ∶ 1.6,among them 1 patient was younger than 6 years old,3 cases were between 6 and 12 years old,and 9 cases were elder than 12 years old.Nine patients were nephrotic syndrome,and 3 patients had renal insufficiency.(2)Ten patients had infection,among them 5 cases were upper respiratory infection with agent unfound,4 patients were mcoplasma infection,1 patient was influenza B virus infection,1 patient had positive result of Hepatitis B surface antibody(HBsAb) and Hepatitis B core antibody (HBcAb),and 2 patients had positive result of purified protein derivative (PPD).(3)Pathological feature of IMN was atypical membranous nephropathy.Atypical membranous nephropathy was characterized by an irregular,thickened glomerular basement membrane(GBM),mesangial cells,and a mesangial matrix with mild to moderate hyperplasia.Immune complexes were stained in the subepithelial region,GBM,and mesangial region under light microscopy.Electron microscopy showed various sizes,density,and shapes of electron-dense deposits in multiple regions.The cases of immunofluorescence were 13 for IgG,10 for C3,9 for IgM,9 for C1q,5 for IgA,2 for C4,and 0 for fibrinogen.Seven patients were strongly positive(3 + and above) for IgG and one patient was strongly positive for C3.(4)Seven patients had complete remission,three patients had partial remission,and three patients had non-remission.Conclusions (1) In this study,children with IMN were mainly girls,and the age distribution was beyond 12 years.Nephrotic syndrome was the most common clinical manifestation.(2)Atypical membranous nephropathy was the most common pathological feature in children with IMN,which should be distinguished from hepatitis B virus-associated glomerulonephritis by testing HBV antigen in renal biopsy.(3) Prednisone was effective for IMN children,but it was suggested to give enough and long course of application.Effect of prednisone combined with cyclophosphamide was still undefined.

Medical Solace Words are a kind of working language used by medical staff who tend to offer solace and encouragement to patients on purpose of medical treatment,and it is a kind of oral language frequently applied by medical staff in the new medical mode.Medical solace aims at decreasing and eliminating patients' negative emotions and improving their mood so as to establish a harmonious relationship between doctors and patients,and make the treatment smooth as well.This article analyzes medical solace words from the perspective of linguistic pragmatics,revealing that for the concealment and complexity of the expressing context for medical words,and the unique programmatic rules of medical language,medical staff should pay much attention to the language hierarchy and grasp the explanatory principle and the guiding principle of medical solace language to achieve the targeted effects of medical solace.

Objective The purpose of this study was to examine the effect of preoperative glucose infusion on glucose transport-4 mRNA ( Glut-4 mRNA) expression in skeletal muscle before and after thoracic operation. Methods Twelve male ASA Ⅰ - Ⅱ patients undergoing elective radical surgery for esophagus cancer were randomly divided into 2 groups : (Ⅰ ) control group; (Ⅱ) glucose infusion group. Patients with hypertension, hyperlipidemia or diabetes mellitus were excluded. The patients in both groups were premedicated with phenobarbitol and atropine. Anesthesia was induced with midazolam 0.1 mg ? kg-1 , propofol 1.5 mg ?kg-1 , fentanyl 4?g?kg-1 and vecuronium 0.15 mg?kg-1 . The patients were mechanically ventilated after trachea! intubatioa Anesthesia was maintained with continuous iv infusion of propofol (80?g ? kg-1? min-1 ) and vecuronium (1.0 ?g?kg-1?min-1) supplemented with droperidol 0.1 mg?kg-1 and fentanyl 6 ?g ?kg-1 given in several boluses. In group Ⅱ 5 % glucose (0.25 g?kg-1) was infused 2 h before operation. Blood samples and 1 g of skeletal muscle were obtained while chest was being opened and closed for determination of plasma glucose and insulin levels and Glut-4 mRNA expression in muscle.
