OBJECTIVE:To study the effects of different extraction methods on the content of cholalic acid from Artificial Bezoar. METHODS: Artificial Bezoar from 3 different habitats was used to extract cholalic acid by hydrolization vs. hydrolization-free method, and the content of cholalic acid was determined by HPLC-ELSD(high performance liquid chromatography with evaporative light scattering detection). RESULTS: The content of cholalic acid in the hydrolyzed sample was higher than that in the non-hydrolyzed sample of the same batch. CONCLUSION: Through hydrolization, the binding cholalic acid in the artificial bezoar was transformed into free cholalic acid so that the content of cholalic acid was increased. Therefore, it is more reasonable to control the quality of Artificial Bezoar by taking the contents of total cholalic acid and free cholalic acid as indexes.

Objective To assess the enhancement characteristic of breast lesions of contrast-enhanced ultrasound (CEUS) in comparison with contrast-enhanced magnetic resonance imaging (MRI).Methods Between August 2011 and March 2013,72 women with 72 lesions were enrolled.All patients underwent ultrasound,CEUS and MRI.The histopathologic results obtained from ultrasound-guided core biopsy or operation excisions were used as the reference standard.CEUS section evaluations were made similar with MRI regarding the size and shape of lesions.Different contrast enhancement patterns including homogeneous/heterogeneous,the tumor areas,the perfusion defect areas,and modality of time-intensity curve were evaluated.Pearson's correlation coefficient,Student's t-tests,and the concordance test were used for evaluation.Results Of the 72 lesions,pathologic examination revealed 56 (77.8％) malignant lesions and 16 (22.2％) benign lesions.The tumor areas measured by CEUS and MRI agreed well,with a correlation of r =0.894,P =0.000.The difference between the two measurements was not significant according to a paired t test (P =0.886).The concordance tests gave a value of the coefficient Kappa =-0.153 (P =0.061),indicating a low concordance between the results obtained with CEUS and those obtained with MRI regarding the enhanced uniformity.There were statistically significant differences in the perfusion defect areas as measured by CEUS and MRI (P =0.01).The CEUS estimates [(0.837 ± 0.827)cm2] were consistently higher than the MRI estimates [(0.576 ± 0.524)cm2].The time-intensity curve patterns between the two groups showed no correlation.Conclusions The enhancement patterns evaluated by CEUS and MRI partly agreed well.There was no direct association between the two methods regarding the enhancement patterns because of the different contrast agent.

Objective To investigate the protective effects of recombinant human erythropoietin (rHuEPO) on acute lung injury (ALI) induced by lipopolysaccharide (LPS).Methods Fourty-five rats were randomly (random number) assigned to three groups,namely control group,model group,and rHuEPO group.ALI was induced by intravenous injection of LPS (6 mg/kg).The rHuEPO (5000 U/kg) was injected intravenously into rats 60 min before LPS challenge.The general status of rats was observed.Twelve hours after modeling,the rats were sacrificed and the tissue samples including lung tissue and blood were collected.PaO2,PaCO2,pH,the lung wet/dry weight ratio,plasma cytokines [interleukin (IL) IL-6 and tumor necrosis factor-alpha (TNF-α)],and inducible nitric oxide synthase (iNOS) were detected.Cytokines were assayed with ELISA method.Pathological changes of lung tissues were observed under light microscope and transmission electron microscopy.Results (1) Compared with the control group,PaO2,pH in the model group and in the rHuEPO group were significantly lower (P ＜ 0.05),and PaCO2 were significantly higher (P ＜ 0.05).Compared with the model group,PaO2,pH in the rHuEPO group were significantly higher (P ＜ 0.05),and PaCO2 were significantly lower (P ＜ 0.05).(2) Compared with the control group,the W/D weight ratio of lung tissues in the model group and the rHuEPO group was significantly higher (P ＜ 0.05).Compared with the model group,the W/D weight ratio of lung tissues in the rHuEPO group significantly lower (P ＜ 0.05).(3) The levels of TNF-o,IL-6 and iNOS in serum of rats in the control group were lower than those in the model group and the rHuEPO group (P ＜0.01).The serum levels of TNF-α,IL-6 and iNOS of rats in the rHuEPO group were significantly lower compared with the model group (P ＜ 0.01).(4) The light microscopy and the transmission electron microscopy showed the model group had histopathologic changes with acute diffuse lung injury manifested by intra-alveolar hemorrhage,exudate,inflammatory cells infiltration,Ⅰ type and Ⅱ type epithelial cell necrosis and detachment,and the pathological changes of lung tissue in the rHuEPO group were not as serious as those in the LPS group,showing only a little inflammatory cells infiltration of focal alveoli.Conclusions Recombinant human erythropoietin can inhibit the genesis of TNF-α,IL-6 and iNOS in serum,modifying the inflammatory response and providing protective effects against acute lung injury induced by sepsis.
