Objective:To investigate the feasibility of dynamic turbidity method for the detection of bacterial endotoxin content in influenza split vaccine. Methods: According to the bacterial endotoxin detection method described in general rule 1143 in Chinese Pharmacopoeia (2015 edition), the reliability test for standard curves of influenza split vaccine, the interference initial screening test, the interference verification test and the endotoxin content were performed or determined, and the results were compared with those by the gel method for the same batches of vaccine. Results:The results of reliability test for standard curves were accordance with the reg-ulations. In the interference initial screening test, vaccine was diluted by 160 times, 320 times and 640 times, and the recovery was between 50% and 200%, which showed no interference. The results of the interference verification test further proved that vaccine with 640 times dilution had no interference effect on test. The bacterial endotoxin contents of 10 batches of influenza split vaccine deter-mined by the turbidity method were less than the limit value of 20 EU·ml-1 , and the results were the same as those determined by the gel method. Conclusion:It is feasible to detect the content of bacterial endotoxin in influenza split vaccine by the dynamic turbidity method, which is worthy of promoted application.

To investigate the suitable site environment for Atractylodes lancea, field trials in different niches was carried out, and the seedling growth, biomass and volatile oil components in different microhabitas was studied. The study found that the survival rate, plant height, volatile oil content of those which growing under the bamboo were significantly higher than those exposed in the open field. The survival rate understory was (76 ± 15.1) %, plant height understory was (77 ± 14. 8) cm and the summation of the four kinds of volatile oil content understory reached up to 4.09%; The same evaluation values of these indicators of the four faces in the open field respectively: survival rate is 30%, plant height was (77 ± 14.8) cm and the summation of the four kinds of volatile oil content was 2.24%. But, the yield of the understory (41 ± 22.3) g was significantly lower than those four faces in the open field (104.5 g) on the contrary. For the four open field towards, the yield of the east facing, which organic matter and other nutritional conditions were better than others, was significantly higher than those in the other facings. A. lancea was found to be an anti-poor and shading-like or growing in east facing slope herb through the correlation analysis of light, temperature, soil and leaf nutrients with seedling growth, biomass and volatile oil components. It also reminds us that the understory herb with high survival rate, low incidence, low management costs, and high medicinal ingredients, although it's production is not so high, but it can be improved by increased organic fertilizer. So the ecological planting patterns which can intercropping herbs with the forest was proposed.

Objective To explore the effects of under-expression of large tumor suppressor 1 (LATS1) on activation of Hippo signaling pathway and differentiation, proliferation, migration of bone marrow mesenchymal stem cells (mMSCs) of micein vitro.Methods mMSCs of C57BL/6 mice were divided into normal control (MSC) group, empty vector control (MSC-GFP) group, LATS1-over-expressing (MSC-LATS1) group, empty vector without LATS1 shRNA control (MSC-shControl) group and LATS1-under-expressing (MSC-shLATS1) group. Lentiviral vectors with activated,inactivated LATS1 (the key molecule of Hippo signaling pathway) modifications and empty vectors were constructed and were used to infect mMSCsin vitro. The transduction efficiencies mediated by the lentiviral vectors were evaluated by fluorescence microscopy and flow cytometry. The mRNA expression of LATS1 was quantified by quantitative real-time polymerase chain reaction (qRT-PCR), and the protein expressions of LATS1, YAP (p-YAP), 14-3-3 were quantified by Western Blot to evaluate the activation of Hippo signaling pathway. Osteogenic and adipogenic differentiation of mMSCs were evaluated through measurement of Runx2, OSX and C/EBPα, PPAR-γ mRNA by qRT-PCR, as well as Alizarin Red S and Oil red O staining. Proliferation of mMSCs was evaluated using methy thiazdyl tetrazolium (MTT) assay. The scratch test and Transwell chamber test were used to analyze the horizontal and vertical migration ability of mMSCs.Results The transduction efficiencies mediated by the lentiviral vectors were 94.74%-96.10%. Compared with MSC-GFP group, the activation of Hippo signaling pathway was promoted in MSC-LATS1 group [LATS1 mRNA (2-ΔΔCT): 4.37±0.21 vs. 1.20±0.04, LATS1 protein (gray value): 2.21±0.06 vs. 1.09±0.10, p-YAP/YAP protein (gray value): 1.51±0.13 vs. 0.98±0.05, 14-3-3 protein (gray value): 1.92±0.18 vs. 1.10±0.09, allP < 0.05], osteogenic and adipogenic differentiation of mMSCs were decreased in MSC-LATS1 group [mineralization (A value):0.13±0.02 vs. 0.40±0.03, Runx2 mRNA (2-ΔΔCT): 0.51±0.02 vs. 0.98±0.09, OSX mRNA (2-ΔΔCT): 0.41±0.04 vs. 1.04±0.09, lipid accumulation (A value): 0.10±0.02 vs. 0.25±0.03, C/EBPα mRNA (2-ΔΔCT): 0.33±0.03 vs. 1.11±0.09, PPAR-γ mRNA (2-ΔΔCT): 0.29±0.02 vs. 1.04±0.10, allP < 0.05], the proliferation rate of mMSCs at 4-7 days was decreased in MSC-LATS1 group and so were the horizontal and vertical migration of mMSCs [wound healing rate: (18.65±3.53)% vs. (40.29±1.87)%, migrated cells (cells/MP): 35.99±6.18 vs. 103.67±17.77, bothP <0.05]. Compared with MSC-shControl group, the activation of Hippo signaling pathway was inhibited in MSC-shLATS1 group [LATS1 mRNA (2-ΔΔCT): 0.16±0.01 vs. 0.98±0.03, LATS1 protein (gray value): 0.38±0.03 vs. 1.04±0.07, p-YAP/YAP protein (gray value): 0.58±0.04 vs. 1.05±0.06, 14-3-3 protein (gray value): 0.14±0.02 vs. 1.02±0.09, allP < 0.05], osteogenic and adipogenic differentiation of mMSCs were increased in MSC-shLATS1 group [mineralization (A value): 0.93±0.13 vs. 0.44±0.05, Runx2 mRNA (2-ΔΔCT): 1.44±0.12 vs. 0.95±0.04, OSX mRNA (2-ΔΔCT):1.67±0.06 vs. 1.10±0.11, lipid accumulation (A value): 0.47±0.06 vs. 0.28±0.04, C/EBPα mRNA (2-ΔΔCT):3.98±0.61 vs. 0.99±0.10, PPAR-γ mRNA (2-ΔΔCT): 3.05±0.36 vs. 0.98±0.14, allP < 0.05], the proliferation rate of mMSCs at 3-7 days was increased in MSC-shLATS1 group and so were the horizontal and vertical migration of mMSCs [wound healing rate: (80.18±6.98)% vs. (46.18±1.01)%, migrated cells (cells/MP): 212.69±41.21 vs. 115.87±35.15, bothP < 0.05].Conclusions Under-expression of LATS1 promotes the differentiation, proliferation, migration of mMSCs by inhibition of Hippo signaling pathwayin vitro.
