The aim of the experiment was to study the amount of oil-producing Rhodotorula strain PR61 as fish feed additive and the effect of wall breaking treatment on feeding effect. A total of 375 red crucian carp seedlings with an average body weight of 4~5 g were randomly divided into five groups with three replicates per group and 25 fish per replicate. Fish in blank control group were fed with 100% basic feed, fish in positive control group were fed with 100% basic feed + 0.25% betaine hydrochloride, fish in T1 group were fed with 99.5% basic feed + 0.5% unbroken red yeast, fish in T2 group were fed with 99.5% basic feed + 0.5% broken red yeast, and fish in T3 group were fed with 99% basic feed + 1.0% broken red yeast. The experiment lasted for 28 d. The results showed that the PR61 strain was rich in nutrition, with protein content up to 45.2%, oil content up to 38.93%, the PR61 strain also contained carotenoid, aspartate, serine and totally 17 kinds of amino acids, and the total amino acid was 44.32%. The survival rate of red crucian carp in T2 group and T3 group was 100%, which was significantly higher than that of blank control group and positive control group (P<0.05). The body weight growth rate of red crucian carp in T3 group was significantly higher than that in other groups (P<0.05), the body length growth rate was significantly higher than that in blank control, positive control group and T1 group (P<0.05), and the feed coefficient was significantly lower than that in other groups (P<0.05). The a* value and L* value of the back skin of red crucian carp in T3 group were significantly higher than those in other experimental groups (P<0.05). The activity of SOD and GSH-Px in serum of red crucian carp in T2 group and T3 group were significantly higher than those in other groups (P<0.05), and the content of MDA was significantly lower than that in other groups (P<0.05). The CAT activity of red crucian carp in T3 group was significantly higher than that in blank control, positive control group and T1 group (P<0.05). The study indicates that adding PR61 in feed can significantly improve the survival rate, weight growth rate and antioxidant enzyme activity of fish fry, decrease the feed coefficient. The growth index of the fish fry reaches the best level and the color of fish body is more vivid when the supplemental amount of red yeast is 1.0%. [ABSTRACT FROM AUTHOR]

Objective　To investigate the anti-inflammatory role of α7 nicotinic acetylcholine receptor (α7nAChR) under inflammatory stress and its mechanisms. Methods　PNU282987 was used for the activation of α7nAChR and LPS was administrated as inflammatory stressor. Realtime PCR was used for the detection of IL-1β, IL-6, TNF-α, M1 macrophage marker CD68, CD86 and M2 macrophage marker CD206, Arg1. Cell immunofluorescence was used for the detection of M1/M2 ratio and Western blot was applied for the detection of autophagy-related proteins. Results　Under the stimulation of LPS, the mRNA levels of proinflammatory cytokines IL-1β, IL-6 and TNF-α, the proportion of M1 macrophage and autophagy process were increased in BV2 microglial cells. However, the administration of PNU282987 significantly decreased the mRNA levels of IL-1β, IL-6 and TNF-α and the proportion of M1 macrophage while increased the proportion of M2 macrophage and the level of autophagy process. Conclusion　Activating α7nAChR plays an anti-inflammatory role in microglial cells under inflammatory stress due to the regulation of M1/M2 macrophage ratio and increase of autophagy level.

Based on environmental protection automatic command system (C4ISRE)， the early warning technology for air nuclear pollution diffusion of the nuclear power plant was proposed. Firstly， an integration simulation environment of sea， land， sky and space for Hong Yanhe Nuclear Power Plant was constructed. Secondly， nuclear pollution diffusion scenario was set up and the HYSPLIT4.9 model was drove by meteorological data according to the scenario. Then， the atmospheric nuclear pollutant transport characteristics were simulated， and the early warning emergency response times for key areas were simulated and deduced. The deduction results showed that nuclear pollution air mass spreads into the waste storage tank factory building of conventional island after 71.885s， the airspace of heat engine repair shop and warehouse after 79.306s， the airspace of wastewater treatment plant and garage after 91.596s， the airspace of the boundary of the plant boundary and sea after 132.267s， plume boundary of emergency region 5km after 655.337s， the airspace of Wong Tung Village after 712s， plume boundary of emergency region 10km after 1240.535s， the airspace of Changxing Island town after 2527.945s， and plume boundary of emergency region 30km after 3468.65s.

We have fabricated chain-like NiCo2O4 nanowires via a facile and environmentally friendly hydrothermal method and followed by calcined in air ambient. In this work, the in-situ electrical properties of the individual chain-like NiCo2O4 nano wires were performed by STM-TEM holder in order to further study the relationship between the microstructure and electrical properties of individual chain-like NiCo2O4 nano wire. The results show that the nanostructure of the NiCo2O4 nanowire gradually changes from chain-like to single -crystalline nanowire with improved electrical properties under 5 V voltage as a result of the electron transfer process of single crystal nanowires will not be blocked. These results provide important reference values for the built of high-performance electrode materials in future . [ABSTRACT FROM AUTHOR]
