Objective To evaluate the effect of antler polypeptides from Cervus elaphus yarkandensis on MC3T3-E1 cells. Methods The concentration of antler polypeptides of Cervus elaphus yarkandensis was measured by BCA protein assay kit. MC3T3-E1 cells were cultured and analyzed by BCIP/NBT chromogenic alkaline phosphatase (ALP) staining kit. After being induced to form mineralized knot, the cells were stained by using Alizarin red staining. Three different concentrations (10, 1.0, 0.1 μg/mL) of antler polypeptides were analyzed by MTT method and micronutrients enzymes standard method to determine the effect of cell proliferation and ALP synthesis. Results The concentration of antler polypeptides was 0.07 mg/mL. The results of in vitro cell activity analysis showed that the positive rate of ALP was 90%and the mineralization knot was stained red. Compared with the control group, the different concentrations of antler polypeptides all showed the function of cell proliferation and the effect was dose-dependent after 3 d and 7 d. Compared with the control group, at the 3 d, three groups of antler polypeptides promoted synthesis and secretion of ALP (P<0.01) and the results showed a dose-dependent effect. Conclusion Antler polypeptides could obviously promote the proliferation of MC3T3-E1 cells and secretion of ALP, which indicated that antler polypeptides have certain effect on osteoporosis.

OBJECTIVE:To investigate the compatibility stability of Fat-soluble vitamin (Ⅱ)/Water-soluble vitamin for in-jection with common electrolytes. METHODS:Referring to clinical common dose,Fat-soluble vitamin (Ⅱ) for injection/Wa-ter-soluble vitamin for injection collective packing [containing Fat-soluble vitamin(Ⅱ) for injection 2 ampoules and Water-soluble for injection 1 ampoule] were respectively mixed with Glucose injection,Potassium chloride injection,Concentrated sodium chlo-ride injection,Sodium bicarbonate injection,Potassium aspartate injection,Potassium aspartate and magnesium aspartate injection, Sodium glycerophosphate injection,Multi-trace elements injection (Ⅱ) to obtain mixture A-H. At room temperature (25 ℃),these mixtures were investigated in terms of appearance,pH value,osmotic pressure molar concentration and the number of insolu-ble particles at 0,1,2,3,4 h. The contents of bacterial endotoxin were tested at 0,4 h. RESULTS:Within 4 h after mixing, there was no significant change in appearance of those mixtures;pH value of mixture H changed greatly (RSD=5.13%,n=5), and that of mixture D and G increased significantly. The osmotic pressure molar concentration of those mixtures had no significantly change(RSD<2%,n=5)and lower than 600 mOsmol/kg. The bacterial endotoxin tests of those mixtures were negative. Two and four hours after mixing,the number of insoluble particles ≥10 μm in mixture B was increased significantly;2,3,4 h after mix-ing,the number of insoluble particles ≥10 μm in mixture E,F,H were increased significantly;0 ,1,2,3,4 h after mixing,the number of insoluble particles ≥10 μm in mixture G was increased significantly. There was statistical significance in the number of insoluble particle ≥10 μm in above mixtures compared to mixture A at the same time point(P<0.05),but it was in line with the standard of 2015 pharmacopeia. One,two,three and four hours after mixing,the number of insoluble particle ≥10 μm in mixture D was increased significantly,there was statistical significance compared to mixture A at the same time point(P<0.05);the num-ber of insoluble particle ≥10 μm in mixture D was beyond prescribed scope of pharmacopeia at 2,3,4 h after mixing. Within 4 h after mixing,both the number of insoluble particle ≥10 μm in mixture C and the number of insoluble particle ≥25 μm in edch mixture had no significant change,in accordance with pharmacopeia standard. CONCLUSIONS:Fat-soluble vitamin (Ⅱ)/Wa-ter-soluble vitamin for injection is not suitable for mixing with Multi-trace elements injection(Ⅱ),Sodium glycerophosphate injec-tion or Sodium bicarbonate injection due to great change of pH value and the number of insoluble particles.

OBJECTIVETo study the effects of monocyte-macrophages (THP-1) in malignant transformation of human bronchial epithelial cells (BEAS-2B) cells induced by coal tar pitch (CTP) and the expression of TNF-α in the process of the cell malignant transformation.

METHODSBEAS-2B cells and THP-1 Cells were divided into four groups: coal tar pitch (CTP) group, benzo(a)pyrene [B(a)P] group, dimethyl sulfoxide (DMSO) group, BEAS-2B and THP-1 co-culture (co-culture group) group. Carcinogenesis model was established. The soft agar colony formation, chromosome aberrations and cell cycle tests were used to detect the cellular malignant transformation. The ELISA assay was utilized to measure the levels of TNF-α in the supernatant of CTP group and co-culture group.

RESULTSThe chromosome number abnormalities could be observed in early stage of the experiment (the 10th generation cells), which showed the increased ratio of aneuploid to polyploid, and the decreased number of diploid. The colony formation rate of co-culture group (the 20th generation cells) was 17.63‰ ± 0.97‰, which was significantly higher than that (13.94‰ ± 0.84‰) of CTP group and that (12.96‰ ± 1.62‰) of B(a)P group (P < 0.05). The proportion of S phase cells in the co-culture group was 44.49% ± 0.68%, which was significantly higher than that (38.19% ± 1.26%) of CTP group and that (36.41% ± 1.19%) of B(a)P group (P < 0.05). The TNF-α level in the co-culture group was significantly higher than that in CTP group (P = 0.001).

CONCLUSIONMonocyte-Macrophages can accelerate the malignant transformation of BEAS-2B cells induced by CTP and increase the expression level of TNF-α.

A novel targeting drug carrier (FA-BO-PAMAM) based on the PAMAM G5 dendrimer modified with borneol (BO) and folic acid (FA) molecules on the periphery and doxorubicin (DOX) loaded in the interior was designed and prepared to achieve the purposes of enhancing the blood-brain barrier (BBB) transportation and improving the drug accumulation in the glioma cells. 1H NMR was used to confirm the synthesis of FA-BO-PAMAM; its morphology and mean size were analyzed by dynamic light scattering (DLS) and transmission electron microscope (TEM). Based on the HBMEC and C6 cells, cytotoxicity assay, transport across the BBB, cellular uptake and anti-tumor activity in vitro were investigated to evaluate the properties of nanocarriers in vitro. The results showed that the nanocarrier of FA-BO-PAMAM was successfully synthesized, which was spherical in morphology with the average size of (22.28 ± 0.42) nm, and zeta potential of (7.6 ± 0.89) mV. Cytotoxicity and transport across the BBB assay showed that BO-modified conjugates decreased the cytotoxicity of PAMAM against both HBMEC and C6 cells and exhibited higher BBB transportation ability than BO-unmodified conjugates; moreover, modification with FA increased the total uptake of DOX by C6 cells and enhanced the cytotoxicity of DOX-polymer against C6 cells. Therefore, FA-BO-PAMAM is a promising nanodrug delivery system in employing PAMAM as a drug carrier and treatment for brain glioma.
