Objective To analyse the nutrients of Acaudina leucoprocta and explore its hypolipidemic effect. Method The nutrients constituents of Acaudina leucoprocta were analyzed by high-performance liquid chromatography,and was compared with Apstichopus japonicus. The hyperlipidemia model was estabolished by feeding SD male mice with high fat feed. The change of liver index and fat coefficient as well as the effects on serum lipid,antioxidant capacity of serum in rats were observed. Results The fat content of Acaudina leucoprocta was only 0.43%,significantly lower than that of Apstichopus japonicus. The content of amino acids in Acaudina leucoprocta was higher than that of Apstichopus japonicus. Acaudina leucoprocta would decrease the liver index,fat coefficient and TC,TG,LDL-C,LDL-C/HDL-C in serum significantly,and increase HDL-C and HDL-C/TC. MDA and NEFA contents were effectively reduced. GSH-Px activitives were enhanced. Conclusion Acaudina leucoprocta is very rich in protein,and low in fat content. It has hypolipidemic and antioxidative effects,and may reduce the oxidative damage caused by high fat diet. Acaudina leucoprocta may be used as a functional food.

BACKGROUND: There are currently many cryopreservation methods for the aminotic membrane, which have varying effects on the ultrastructure and biological activity of amniotic membrane, but on no one is effective.
OBJECTIVE: To compare the effects of different cryopreservation methods on the ultrastructure and viability of aminotic membrane and to seek the ideal cryopreservation method.
METHODS: Aminotic membrane separated from the fresh placenta was preserved respectively with deep-frozen cryopreservation and vitrification, and everyway was run for 3 and 6 months. Fresh aminotic membrane was used as control. The ultrastructure of aminotic membrane was observed by transmission electron microscopy, and the viability of aminotic membrane was assessed by microcomputer analysis system for biological oxygen consumption, and immunohistochemical staining combined with image analysis system was used for lactate dehydrogenase activity.
RESULTS AND CONCLUSION:After 3 and 6 months of crypreservation, the damage to the ultrastructure of aminotic membrane by vitreous cryopreservation was slighter than that of amniotic membrane cryopreserved at-80℃. Compared with the fresh aminotic membrane, the gray value of lactate dehydrogenase and partial pressure of oxygen were significantly decreased in the cryopreserved aminotic membrane by deep-frozen cryopreservation at 3 and 6 months (P < 0.05) and by vitreous cryopreservation at 6 months (P < 0.05), but there was no statisticaly significant difference in the change rate of oxygen partial pressure and the gray value of lactate dehydrogenase between the fresh aminotic membrane and the cryopreserved aminotic membrane by vitreous cryopreservation at 3 months. The present study led to the conclusion that vitreous cryopreservation protocol alows to not only maintain the integrity of AM, but also to preserve the viability of the cels. So the vitreous cryopreservation is superior to the deep-frozen cryopreservation for cryopreservation of aminotic membrane.

Natural product is an important source of new drug research and development (R&D). Traditional Chinese medicine (TCM) innovation is the key step for its modernization and internationalization. However, due to the complexity of TCM, there are many difficulties and confusions in this process. Target-based drug discovery is the mainstream model and method of R&D. TTD, short for therapeutic target database, is developed by National University of Singapore. Besides a large amount of information on drug targets, the database also contains considerable information related to natural products. This paper briefly introduces the TTD, analyzes the natural products derived drugs/compounds recorded in TTD, which we think might provide some inspiration for the innovation of TCM.

BACKGROUND: Classic isolation method of bone marrow mesenchymal stem cells (BMSCs) is Percoll density gradient centrifugation. Blood cell component was removed. However, this method is complicated. Preparation density was needed when isolating dog bone marrow. Moreover, centrifugation was frequent, which had a great damage to cells. OBJECTIVE: To establish methods of the isolation, proliferation, culture and osteoinduction of canine BMSCs, and observe the in vitro proliferation and ability to osteoinduction differentiation. METHODS: 10 mL bone marrow was extracted from dog posterior superior iliac spine, heparin anticoagulation, diluted using Hanks juice, treated with 1.077 g/mL Ficoll solution 3 mL, and centrifuged at 2 000 r/min for 20 minutes. Karyocytes were absorbed to form white cloudlike layering interface, and then centrifuged twice using DMEM supplemented with fetal bovine serum, incubated at 12×10~4/cm~2 at 37 ℃ in a 5% CO_2 incubator. Following subculture, cells were incubated in DMEM containing dexamethasone, β-sodium phosphoglycerol and ascorbic acid 2-phosphate. Immunocytochemical staining and immunofluorescence staining were utilized to detect osteocalcin, osteopontin and type Ⅰ collagen expression in osteoblasts. Alkaline phosphatase staining and alizarin red staining were performed. RESULTS AND CONCLUSION: 1.077 g/mL Ficoll density gradient centrifugation was used to isolate karyocytes that were significant compared with Percoll solution. Obtained BMSCs had high purity, good growth and the mean doubling time was 24 hours. Following in vitro osteogenic incubation of dog BMSCs, osteocalcin, osteopontin and type Ⅰ collagen showed positive expression. Alkaline phosphatase staining demonstrated bluish-green cytoplasm. Alizarin red staining showed red nodes in extracellular matrix, and could differentiate into osteoblasts in vitro.
