Objective To optimize the vacuum drying process of extract paste of Huangqi Baihe Granules (HBG) and evaluate the physical quality of powder. Methods With drying temperature, vacuum degree, and material thickness as independent variables, the comprehensive evaluating indexes of content of calycosin 7-O-β-D-glucopyranoside, hesperidin, crude polysaccharide, ethanol extraction amount, and drying rate as response values, Box-Behnken design-response surface methodology and G1-entropy method were used to optimize the vacuum drying process. The similarity of fingerprints between extract powder dried by the optimized technology and extract paste was compared. Additionally, the properties of powder were evaluated comprehensively with nine physical indicators, including relative homogeneity index, bulk density, tap density, interparticle porosity, compressibility, Hausner ratio, angle of repose, moisture content, and hygroscopicity. The physical fingerprint of powder were established to evaluate the quality consistency of different batches of extract powder. Results The optimal drying parameter was as follows: the drying temperature was 68 ℃, the vacuum degree was 0.07 MPa, the material thickness was 6 mm. Three verification experiments were carried out under these conditions and the average comprehensive evaluating indexes of vacuum drying was 91.05, which was close to the model prediction 91.87, and the relative error was 0.89%. Compared with the extract paste, the similarity of fingerprint of extract powder were more than 0.91. The similarity of chemical and physical fingerprint of three batches of extract powder were higher than 0.99. Conclusion The optimized vacuum drying technology of extract paste of HBG is stable and feasible.

OBJECTIVETo provide evidence for Chinese medical treatment of children with EB virus infection by exploring its clinical efficacy from multiple angles.

METHODSTotally 81 children patients were randomly assigned to the treatment group (46 cases) and the control group (35 cases). Patients in the treatment group took Chinese medical decoction, while those in the control received intravenous dripping of Ganciclovir and oral administration of pidotimod. The treatment period for the two groups was 2 weeks. Patients were followed-up till the 12th week. Clinical symptoms such as fever, lymphadenopathy and hepatosplenomegaly, as well as lab indices such as abnormal lymphocyte percentage, EB virus antibody, virus DNA load, T cell subsets, immunoglobulin, and so on were observed before and after treatment, at week 4 and 12 of follow-ups.

RESULTS(1) The total effective rate at week 2 was 95.6% in the treatment group, higher than that of the control group (94.3%), but there was no statistical difference between the two groups. (2) The time for defervescence, duration of pharyngeal hyperemia, duration of swollen tonsils was shorter in the treatment group than in the control group (P<0.05). The subsidence of lymphadenopathy, hepatomegaly, and abnormal lymphocytes was better in the treatment group than in the control group (P < 0.05). (3) The positive cases of peripheral blood hetero-lymphocyte was significantly reduced after treatment, at week 4 and 12 of follow-ups both in the treatment group and the control group (P < 0.01). The expression of IgA and IgM decreased after treatment in the two groups when compared with before treatment in the same group (P < 0.05, P < 0.01). IgG in the treatment group also obviously decreased after treatment, at week 4 and 12 of follow-ups (P < 0.05, P < 0.01), while it decreased only after treatment in the control group (P < 0.05). Activities of AST and ALT in the treatment group and the AST activity in the control group were markedly improved when compared with those before treatment (P < 0.05). Compared with the control group, the abnormal lymphocyte positive case number obviously decreased in the treatment group after treatment, at week 4 and 12 of follow-ups (P < 0.05). (4) After treatment, at week 4 and 12 of follow-ups, CD3+ and CD8+ significantly decreased; CD4+, CD4/CD8, and B cells significantly increased in the two groups, when compared with before treatment (P < 0.05). NK cells significantly increased more in the treatment group after treatment, at week 4 and 12 of follow-ups, higher than before treatment as well as the control group (P < 0.05). (5) EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the two groups after treatment, at week 4 and 12 of follow-ups (P < 0.05). Compared with the control group, EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the treatment group after treatment and at week 4 of follow-ups (P < 0.05).

CONCLUSIONSTreatment of EB virus infection by Chinese medical treatment was effective. It could promote the recovery of EB viral infection, and reduce the risk of vicious disease after EB viral infection.

Aim To investigate the effect of the inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A(HMG-CoA)reductase enzyme,simvastatin on E-Selectin ex-pression and adhesive function assay induced by CD40L.Methods Human umbilical vein endothelial cell(HUVEC)was cultured from ECV304 cell strain.Then E-Selectin expression and adhesion of lymphocytes to endothelial cells induced by CD40L and interfered with different concentrations of simvastatin or simvastatin(5 ?mol?L-1)+mevalonic acid were determined by RT-PCR and FCM analysis.Results Preincubation of HUVECs with simvastatin(0~10 ?mol?L-1)decreased the expression of E-Selectin induced by CD40L in a concentration-dependent manner.Mevalonic acid(400 ?mol?L-1)inhibited the restrain of simvastatin on E-Selectin expression.Moreover,preincubation with simvastatin,decreased significantly adhesion of lymphocytes to endothelial cells induced by CD40L.Conclusions Simvastatin inhibits activation of endothelial cells induced by the CD40L/CD40 pathway through HMG-CoA dependent effect.

Objective To investigate the imaging features of Budd-Chiari syndrome(BCS) on 64 slice spiral computed tomography(64SCT) and the diagnostic value of 64SCT for BCS.Methods Twenty-nine patients diagnosed as BCS by 64SCT were retrospectively included into this study and all the patients were researched by digital substraction angiography(DSA).Two abdominal radiologists analyzed the CT imaging features of BCS,paying attention to the vascular lesion,the morphology abnormality of the liver and the degree of portal hypertension,with review of DSA findings.Results ①The accuracy of 64SCT for BCS was 93.1%(27/29),and there were 2 false positive cases and no false negative case.The accuracy of 64SCT for those patients with thrombosis of inferior vena cava(IVC) and(or) hepatic vein(HV) was high as compared to those with stenosis of IVC and(or) HV.②The morphology abnormality of the liver included hepatomegaly(24 cases),low attenuation(27 cases) and inhomogeneous pattern of parenchymal contrast enhancement(5 patients in arterial phase and 19 patients in portal vein phase).③The images of all the patients showed the features of portal hypertension.Conclusion The accuracy of 64SCT for BCS is satisfactory and the false negative is seldom.The 64SCT could accurately display the morphology abnormality of the liver and the compensatory circulation in BCS patients.For those patients with stenosis of IVC and(or) HV,however,the diagnostic power of 64SCT is limited.

Objective:To study the effect of Bcl-2 short hairpin RNA (shRNA) in enhancing methotrexate (MTX)-induced apoptosis of Raji cells. Methods:Expression plasmid containing Bcl-2 shRNA was transfected into Raji cells by lipofectmine 2000 and then the transfected cells were treated with MTX. The expression levels of Bcl-2 mRNA and protein were evaluated by RT-PCR and immunofluorescence method at 48 h of transfection. MTT assay was used to analyze cell proliferation at 24, 48 and 72 h. Apoptosis was detected by Giemsa staining and flow cytomertric cell cycle analysis. Results:After transfection with Bcl-2 shRNA, the expression levels of Bcl-2 mRNA and protein in Raji cells were significantly decreased (P<0.05). Bcl-2 shRNA transfection plus MTX treatment induced marked apoptosis, decreased in cell proliferation activity, and increased in apoptotic rate. The difference was significant compared with MTX group, negative shRNA plus MTX group, Bcl-2 shRNA group, and empty plasmid plus MTX group (P<0.05). Conclusion:Bcl-2 shRNA could enhance MTX-induced apoptosis and inhibition of cell proliferation in Raji cells.
