Abstract: Schistosomiasis, an important zoonotic parasitic disease, is one of the six major tropical diseases identified by WHO, and also one of the most important parasitic diseases for prevention and control in China. After more than 70 years of efforts, the prevention and control of schistosomiasis in China has made great achievements, and the current epidemic of schistosomiasis in China has entered an extremely low epidemic state, but the distribution base of the only intermediate host of schistosomiasis, Oncomelania hupensis, is still large. For now, the techniques used to monitor schistosomiasis have shortcomings such as time-consuming, laborious and low sensitivity, which cannot meet the current needs of China. Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water or air) without isolating any target organisms, which is a complex mixture of genomic DNA and its degradation products from different organisms in the same environment. eDNA technology can reflect the community or species composition information in the ecosystem through DNA extraction and detection of environmental samples. Compared with traditional biological monitoring methods, eDNA technology has the advantages of high efficiency, high sensitivity and environmental friendliness. eDNA has been successfully used for the specific detection of Schistosoma mansoni, Schistosoma haematobium and Schistosoma japonicum. This paper reviews the current detection methods of eDNA, the application and technical limitations of eDNA technology in schistosomiasis monitoring, aiming to provide scientific reference for research in the field of schistosomiasis surveillance.

OBJECTIVETo investigate the expression of long non-coding RNA-HOTAIR in prostate cancer cells and its effects on the growth and metastasis of the cells.
METHODSUsing quantitative reverse-transcription PCR (qRT-PCR), we determined the relative expression of HOTAIR in the normal human prostate epithelial cell line RWPE-I and prostate cancer cell lines PC-3 and DU145. We detected the effects of HOTAIR on the cell cycle and invasiveness of prostate cancer cells by RNA interference, flow cytometry, and Transwell mitration assay.
RESULTSThe expressions of HOTAIR in the PC3 and DU145 cells were increased 3.2 and 5.7 times, respectively, as compared with that in the normal RWPE-1 cells. After si-HOTAIR interference, the prostate cancer cells were arrested in the G2 phase and downregulated in the G1 phase. The invasive ability of the prostate cancer cells was evidently inhibited, with the inhibition rates of 32% and 44% of the PC3 cells and 43% and 34% of the DU145 cells for si-HOTAIR1 and si-HOTAIR2, respectively.
CONCLUSIONIncRNA HOTAIR is highly expressed in prostate cancer, which is associated with the growth and invasiveness of prostate cancer cells. HOTAIR is potentially a novel marker for the diagnosis and prognosis of prostate cancer.

The 11-hydroxylation of 16alpha,17alpha-epoxy-4-pregenene-3,20-dione as a useful intermediate for the preparation of hormones can be achieved by the mycelium of Absidia coerulea at higher conversion rate than using other strains. In this paper 16alpha,17alpha-epoxy-4-pregenene-3,20-dione mixed with a little water, beta-cyclodextrin, Tween-80 was introduced into the fermentation broth after ultrasonication to increase pseudo-water-solubility of the hydrophobic substrate. This pseudo-crystallo feed could avoid the toxicity of organic solvents and was more available for the microbial transformation. The multi layer feed-forward neural network was used to setup a model which indicated the relationship between medium and feed components and the conversion rate. Particle swarm optimization (PSO), which was a stochastic global optimization algorithm and of which the convergence speed was high, was applied to obtain the optimal concentration of the medium and feed components. At optimum conditions with the pseudo-crystallo feed, the conversion rate of 16alpha,17alpha-epoxy-4-pregenene-3,20-dione at an initial concentration of 10 g/L was 87.5% in shaking flasks. The conversion rate of the substrate was up to 86.6% at higher concentration of 20 g/L feed in a 3.7 L fermentor.
