Objective: To study the morphological changes of erythrocytes in hyperl ipemia. Methods: Wistar rats used were divided into normal control group (NC) an d hyp erlipemia group (HL, fed with high lipid diets). The morphological changes of er ythrocytes were observed by SEM, and classified and counted. Results: Compared with NC,percentage of normal erythrocytes in HL were decreased from 76.4 % to 45.7%. The percentage of echinocytes, spherostomatocytes and target cells w ere increased from 4%, 2.2%, 1.5% to 17.3%, 10.4%, 5.8% respectively. The nu mber of ridged cells and abnormal cells was a little increased.Conclusion: The number of abnormal erythrocytes was significantly increased in h yperlipemia.

Objective To optimize the preparation process for Fangji Huangqi Granules. Methods With the extraction rates of tetrandrine, fanchinoline, astragaloside Ⅳand solid as the parameters, the extract conditions of Fangji Huangqi Granules were optimized by orthogonal design . Then the anti-inflammation effect of the extracts was observed on the mice and rats. Results The optimal preparation process was as follows:the mixture of medical materials was firstly refluxed twice with total 10 times of 70 %alcohol,1.5 hours for each time, and then extracted twice with total 12 times of boiling water ,1.5 hours for each time. The anti-inflammation effect of the extracts was obvious on the mice and rats. Conclusion The optimal preparation process is reasonable and with high extraction rate of active components.

The macroporous resin separation technology has been mainly applied in the enrichment of saponins, flavonoids, alkaloids and other ingredients, and used in the removal of heavy metal impurities and pesticide residues in recent years. This paper focuses on the synthesis of the new-type macroporous adsorption resin LKS-11 according to the molecular structure characteristics of procymidone. Specifically, the selective absorptive property and other advantages of macroporous resin were utilized to analyze the procymidone removal efficiency in ginseng extracts from different sources. The type of macroporous resins, absorptive property and desorption conditions were observed respectively by static and dynamic adsorption methods to determined the optimum process conditions. According to the results, LKS-11 showed a good absorptive property to procymidone in ginseng extracts and provided a theoretical basis for studies on the removal of procymidone residues from ginseng extracts by using macroporous adsorption resin. Because of no secondary pollution on samples, low production and operation costs, high procymidone removal efficiency and high product recovery rate, this method is suitable to be applied in production.

Objective: To verify the hypothesis that cells with characteristics similar to bone marrow mesenchymal stem cells(MSCs) can be isolated and cultured from human fetal articular cartilage. Methods: Human fetal articular cartilages were harvested from fetuses aborted between 12 and 20 weeks. Cells were grown in monolayer cultures in IMDM medium containing antibiotics, L-glutamine and fetal calf serum. Cells were induced to differentiate into adipocytes, osteoblasts, chondrocytes, and neurons. At various time points, parental and passaged cells were subjected to FACS analysis to determine cell phenotype. Results: We successfully isolated and cultured MSCs from human fetal articular cartilage. These cells had the same morphology, phenotype, and ability to differentiate in vitro as MSCs of bone marrow origin. Conclusion: This study shows that cells with characteristics of MSCs can be isolated and cultured from human fetal articular cartilage.
