Successful models were treated with a combination of Xuefuzhuyu decoction and 10g of astragalus. The experimental results showed that neuronal morphology and structure recovered, nerve growth factor mRNA expression increased in brain tissues, and neurological function signifi-cantly improved. There was no significant difference in these measures compared with rats treated with Xuefuzhuyu decoction alone or a combined treatment of Xuefuzhuyu decoction with 40 g as-tragalus. These experimental findings revealed that, Xuefuzhuyu decoction combined with astra-galus may up-regulate the expression of nerve growth factor mRNA and accordingly exert a neu-roprotective effect; however, this protection is not dependent on astragalus dosage.展开更多

In this study, the dissolution of metallic elements during the material decoction process was investigated using laser-induced breakdown spectroscopy(LIBS). The Ca, Mg, Al, and Fe in the drug residues, liquid, and vapor were selected for the study of the transfer of elements after different decocting times. It was found that the intensities of the spectral lines for these elements in the drug liquid increased with increasing decocting times.The contrast trend was observed in the residues and only calcium was detected in the vapor.Furthermore, the relative mass concentrations of Ca, Mg, Al, and Fe in the liquid were quantitatively determined by a combination of the standard addition method and calibrationfree-LIBS method by adding the standard concentration solution of Cu and Cd elements into the drug liquids, it can be found that the maximum error between Cd concentration calculated by internal CF-LIBS and the standard is within 10%. This provides a new method of achieving the on-line monitoring and analysis of metallic elements in the production of traditional Chinese medicines.展开更多

Methods: Ninety two cases of liver fibrosis of chronic hepatitis B were randomly divided into group A and group B. Patients in group A received APAFD for 48 weeks, and in group B, they received JSBC for 48 weeks. The effects on the level change of hyaluronic acid (HA), laminin (LN), pro collagen Ⅲ (PCⅢ) and collagen Ⅳ (CⅣ) as well as liver functional tests and liver biochemical parameters before and after treatment were observed.Results: Level of serum HA, LN, PCⅢ and CⅣ in group A declined more obviously than that of group B, the difference was significant ( P <0.01). The liver functional tests such as total bilirubin (TB), alanine aminotransferase (ALT), albumin/globulin (A/G) ratio, hepatitis related serum biochemical parameters such as cholylglycine (CG), serum ferritin (SF), prealbumin (PC) of group A were all improved more significantly than that of group B ( P <0.01).Conclusion: APAFD is more effective than JSBC in treating liver fibrosis of chronic hepatitis B and in the inhibition of hepatic inflammation, hence it is a good composite Chinese herbal preparation against liver fibrosis.展开更多
