METHODS： Fingerprints of WRCP, which were composed of aqueous extracts of Aconitum carmichae/i, Rhizoma bolbostemmatis, Phytolacca acinosa, Panax notoginseng and Gekko swinhonis Gdenther, and aconitine, which could be isolated from Aconitum carmichaeli and have the potential toxicity, were identified by high pressure liquid chromatography. Bel-7402 cells were grown in the presence of WRCP, As203 or all-trans-retinoic acid （ATRA）. Cell proliferation and viability were determined by trypan blue stain. Apoptosis and cell cycle of Bel-7402 cells were detected by flow cytometry. Morphologic and ultrastructural variations were determined under optic and electronic microscopy. The secretion of alpha-fetoprotein and albumin was detected by radioimmunoassay. RESULTS： The average quality of aconitine is 1.15：1： 0.10 μg per 7.5 g extracts. WRCP could suppress the proliferation and viability of Bel-7402 cells. The percentage of apoptosis cells and S phase cells increased on WRCP-treated cells. Treated with WRCP, Bel-7402 cells showed ultrastructural features of differentiation. The alpha-fetoprotein secretion decreased while the albumin secretion increased （P 〈 0.001, P 〈 0.001, respectively） markedly in WRCP-treated cells. CONCLUSION： WRCP can affect the proliferation, differentiation and apoptosis of Bel-7402 cells. It can arrest cells in S phase and has strong cytotoxicity to Bel-7402 cells.展开更多

Twelve permanent transects were set in three distinct functional zones from February to April 2012 and May to July 2013. A total of 112 ungulate signs were recorded on these transects. In addition, 20 camera traps were used to survey ungulates and predators in 2012, while the following year we extended the survey site by using 30 cameras. Overall, 6641 capture events on 2930 camera days were obtained, presenting a variety of ungulate spe- cies： muntjak （Muntiacus muntjak）, tufted deer （Elaphodus cephalophus）, serow （Capricornis sumatraensis） and wild boar （Sus scrofa）. Population structure and composition of ungulates was compared in different functional zones using a single factor of variance analysis in SPSS software. Significant differences in the distribution of un- gulates were recognized between the core zone and experimental zone, but not in other zones due to differences in habitat types and management practices of the nature reserve. Using ArcGIS analysis and Salford Predictive Modeler software, we ran several predictive models to understand which areas are most suitable for ungulates. We conclude that muntjac and wild boar are mainly distributed in the experimental zone, serow are more common in the core zone, while tufted deer are located evenly in the three functional zones. Finally, suggestions for effective and feasible management strategies and techniques for Matoushan National Nature Reserve were recom- mended based on the results and analysis in this study.展开更多

Among terrestrial organisms, biofluorescence has been commonly recorded in arthropods, but rarely from vertebrates （Lagorio et al. 2015）. It has long been known from parrots （Hausmann et al. 2003） and has recently been recorded from a frog （Taboada et al. 2017） and from chameleons （Chamaeleonidae： Protzel et al. 2018）.展开更多
