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.

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 investigate the changes of airway resistance before and after Bronchial Diulation Test in patients with senile asthma and the effect of age on the degree of airway resistance. Methods A total of 29 (> 60 years)senile asthma patients and 21 younger(< 60 y)patients were enrolled in the study. The status of their pulmonary function was determined by MEFV(Maximum expiratory flow?volume curve)and an IOS(impulse oscillometry) system before and after Bronchial Diulation Test,The spirometric indexes such as forced vital capacity,total respiratory impedance,respiratory resistance and respiratory system reactance were collected and analyzed. Results Significant decreases of indexs were found after Bronchial Diulation Test compared with those before Bronchial Diulation Test in the study group(P<0.05,respectively). No significant difference in improvement of indexs was found between the group of patients with senile asthma(age > 60 years)and the group of healthy control(age < 60 years ). Each index of the airway resistance has a very good correlation with FEV1%,with the highest degree of relation is X5%. Conclusion The airway resistance of senile asthmatic patients was significantly improved after diuslation test and these indexes IOS would be valuable in evaluating the changes of airway resistance of senile asthma.
