Study on Quality Standard of Fufang Xiongdan Yinchen Granule / 中国中医药信息杂志

Objective To establish the quality standard for Fufang Xiongdan Yinchen Granule. Methods TLC was employed to identify Pulvis ellis urs, Capillary Wormwood Herbin, Atractylodis Macrocephalae Rhizoma and Glycyrrhizae Radix, and HPLC was used to determine the content of sodium tauroursodeoxycholic acid in Fufang Xiongdan Yinchen Granule. Kromail 100-5 C18 column (4.6 mm× 250 mm, 5 μm) in an oven at 25 ℃ was need, with a mobile phase consisting of methanol-0.03 mol/L sodium dihydrogen phosphate solution (60∶40, pH=4.4) and UV detector at 210 nm, the flow rate was 1.0 mL/min. Results Pulvis ellis urs, Capillary Wormwood Herbin, Atractylodis Macrocephalae Rhizoma and Glycyrrhizae Radix can be detected by TLC. The linearity of sodium tauroursodeoxycholic acid was obtained in the range of 0.182 1-1.821 mg (r=0.999 98). The average recovery was 100.39%, and RSD was 1.70% (n=6). Conclusion The method is simple, accurate, specific, and can control the quality of Fufang Xiongdan Yinchen Granule effectively.

Effect of total alkaloids of Rubus alceaefolius on oxidative stress in rats with non-alcoholic fatty liver disease / 中国中药杂志

<p><b>OBJECTIVE</b>To study the effects of total alkaloids of Rubus alceaefolius (RAP) on non-alcoholic fatty liver disease (NAFLD) rats and explore its possible mechanisms.</p><p><b>METHOD</b>Sixty SD rats were randomly divided into six groups: control group, model group, compound methionine and choline bitartrate tablets (CMCB)group and three RAP groups treated respectively with low, middle and high dose of RAP. The NAFLD model was induced by feeding fat-rich food. NAFLD rats were administrated with 0.35 g x kg(-1) CMCB and 0.36, 0.72, 1.44 g x kg(-1) RAP for 4 weeks respectively. The weight index of liver was measured. Hepatic histolog ical changes were observed. The concentration in serum of aspartate amino transferase (AST), alanine amino tranferase (ALT), tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) were determined. The mRNA expressions of SOD, MDA, TNF-alpha and IL-6 in hepatic tissue were detected.</p><p><b>RESULT</b>Compared with the model group, degree of steatosis of hepatic lobule was improved, the weight index of liver was decreased, serum levels of ALT, AST, TNF-alpha and IL-6 were significantly lower in the high and middle dose RAP group (P < 0.05 or P < 0.01). The levels of SOD and MDA in hepatic tissue were lower in the high dose RAP group (P < 0.05). The mRNA expressions of TNF-alpha and IL-6 in hepatic tissue were decreased (P < 0.05 or P < 0.01).</p><p><b>CONCLUSION</b>RAP can protect liver in experimental NAFLD, and its possible mechanisms may be concerned with clearing the oxygen free radical, reducing the product of lipid peroxidation, inhibiting the release of inflammatory cytokines and reducing nflammatory response.</p>

Ultrastructure and TUNEL staining on inhibition of Rubus alceaefolius total alkaloids for apoptosis of liver in rat models of acute hepatitis / 中国中药杂志

<p><b>OBJECTIVE</b>To investigate the anti-apoptosis effects of Rubus alceaefolius total alkaloids in rats with hepatic injury.</p><p><b>METHOD</b>The hepatic injury model of rat was induced by intraperitoneal injection with CCl4. Sixty SD rats were randomly divided into the normal group, the model group, the R. alceaefolius total alkaloids intervened group, and the bifendate intervened group. The expressions of the levels of liver cell apoptosis were determined by TUNEL. Ultrastructures of the liver cells were observed with transmission electron microscope.</p><p><b>RESULT</b>Compared with the model group, the degree of hepatic injury and the positive expressions of apoptosis in liver tissues in the R. alceaefolius total alkaloids intervened groups and the bifendate intervened group were significantly lower.</p><p><b>CONCLUSION</b>R. alceaefolius total alkaloids could reduce the pathological changes and degree of hepatic injury in rats, which may be partially through inhibiting the expressions of apoptosis in liver tissue.</p>

Optimization of the Extraction Process of Qianliening Granules by Orthogonal Test / 浙江中医药大学学报

[Objective]To filter and optimize extractive technology of Qianliening granules.[Methods]The optimization extractive technology of Qianliening granules was investigated using orthogonal design with the availability component extracting from the drug as the index.[Results]The optimal condition for the extraction of Radix Astragali group was 10 folds amount of water,3 times,1.5 hours each time.The optimal condition for the extraction of Rheum officinal Baill.group was 6 folds amount of 60% alcohol,2 times,two hours and 1.5 hours each time.[Conclusion]The optimized extractive technology is scientific and efficient.

Effect of Kangmeifu burns ointment on expressions of EGF,TNF-? and TGF-?_1 in wound tissue of burned rat models / 中华中医药杂志

Objective:To treat the burned wounds with Kangmeifu burns ointment and observe the expression levels of EGF,TNF-? and TGF-?1 in the process of wound healing.Methods:Immunohistochemistry and image analysis methods were conducted to examine the expressions of EGF,TNF-? and TGF-?1 in both groups at 3,5,7,9 and 14 days after scalding.Results:①Expression of EGF:EGF began to express from the 1stday.It expressed significantly at the 5th day,maintained a higher level at the 7th and 14th days.In the blank control side,the peak expression occurred at the 7th day.② Expression of TNF-?:TNF-? had two peaks respectively in both sides.The peaks in the blank control side ocurred at the 3th and 9th days respectively,and the peaks in the Kangmeifu burns ointment treated side ocurred at the 3th and 7th days,and the second peak was obviously earlier than that in the blank control side.③Expression of TGF-?1 :TGF-?1 began to express from the 1stday.It expressed significantly at the 5th day,and reduced at the 9th day.In the blank control side,the peak expression occurred at the 7th day.In the blank control side,there was almost no TGF-?1 expression at the lst day.It expressed weakly at the 3th day.The peak expression occurred at the 7th day.Conclusion:Kangmeifu burns ointment can accelerate the process of wound tissue healing through enhancing EGF,TGF-?1 expression at the beginning and inhibiting TNF-? overexpression later.

The Impact of Artemisia Scopariae on Hereditary Injury Induced by Aflatoxin B_1 / 中医杂志

It was observed that the per mil rate of micronuclei of marrow cells in mice induced by AFB_1 decreased with the increasing dosage of Artemisia Scopariae. While A. Scopariae revealed dosage-effect relation in the percentage of CA(chromatin abnomalities)induced by AFB_1 and the inhibition effect on SCE(sister chromatin exchange)per cell.
