Effect of Hanfangji compound on proliferation of hepatic stellate cells and expressions of TTR, ITIH1 and SERPINF2 / 中国中药杂志

<p><b>OBJECTIVE</b>To observe and compare the effects of Hanfangji Compound and IFN-gamma on expressions of transthyretin (TTR) , inter-alpha inhibitor H1 (ITIH1) and serpin peptidase inhibitor clade F member 2 (SERPINF2) of hepatic stellate cells (HSC-T6).</p><p><b>METHOD</b>Hanfangji Compound and IFN-gammaof different concentrations were used in hepatic stellate cell-T6 (HSC-T6) for 48 h. Flow cytometer was used to detect the effects of Hanfangji Compound and IFN-gamma on HSC proliferation. RT-PCR method was adopted to detect mRNA expressions of TFR, ITIH1 and SERPINF2. TTR, ITIH1 and SERPINF2 secretions were detected by ELISA. The protein localizations of TTR, ITIH1 and SERPINF2 were examined by immune fluorescence. The protein expression of TfR and ITIHI were determined by Western blot.</p><p><b>RESULT</b>After Hanfangji Compound and IFN-gamma were adopted in HSC-T6, compared with the control group, the cell proliferation was inhibited obviously (P < 0. 05) , protein expressions of TTR, ITIH1 and SERPINF2 and mRNA expression increased significantly, with certain correlation with concentrations of Hanfangji Compound. The 2. 5 g L-I Hanfangji Compound group was superior to the IFN-gamma group (P <0. 05).</p><p><b>CONCLUSION</b>Hanfangji Compound can inhibit HSC proliferation, upregulated TTR, ITIH1 and SERPINF2 proteins and mRNA expression, which may be one of mechanisms of anti-hepatic fibrosis of Hanfangji Compound.</p>

Development of a multiple ligator and its endoscopic therapy for patients with esophageal varices / 中国医疗器械杂志

The ligators we have developed is a kind of economical and effective six-ring ligator. Endoscopic variceal ligation (EVL) was performed to treat bleeding from esophageal varices in patients with liver cirrhosis using self-made ligator and foreign multiple ligator. There are similar effects with both self-made ligator and foreign mutiple ligator in the control of variceal bleeding, variceal obliteration and rebleeding (93.8%, 87.5%, 0 in the group with self-made ligator, 94.5%, 87.1%, 2.4% in the group with foreign multiple ligator, P>0.05). In terms of the quality index, successful operation rate, hemastatic rate, variceal obliteration rate, rebleeding rate, complications and variceal recurrence rate, the self-made ligator is as good as the foreign multiple ligator, but much cheaper.

ICAM-1 expression in experimental fibrosistissue affected by Radis Astragali / 中国临床药理学与治疗学

Aim To observe the antifibrotic effect of Radis Astragali and to explore the mechanism. Methods The fibrosis of animal model was induced with CCl4,and the model animals were treated with Radis Astragali in treatment group and saline in control group respectively. Results The serum hyaluronic acid (HA), fibrosis score and ICAM_1_positive hepatocytes all the decreased in the treatment group as compared to those in the control group.Conclusion Radis Astragali has satisfactory effect on experimental fibrosis. The mechanism may be correlated with its affection on ICAM_1 in liver tissue.
