The microbial community structures in an integrated two-phase anaerobic reactor（ITPAR）were investigated by 16 S r DNA clone library technology. The 75 L reactor was designed with a 25 L rotating acidogenic unit at the top and a 50 L conventional upflow methanogenic unit at the bottom, with a recirculation connected to the two units. The reactor had been operated for 21 stages to co-digest fruit/vegetable wastes and wheat straw, which showed a very good biogas production and decomposition of cellulosic materials. The results showed that many kinds of cellulose and glycan decomposition bacteria related with Bacteroidales,Clostridiales and Syntrophobacterales were dominated in the reactor, with more bacteria community diversities in the acidogenic unit. The methanogens were mostly related with Methanosaeta, Methanosarcina, Methanoculleus, Methanospirillum and Methanobacterium; the predominating genus Methanosaeta, accounting for 40.5%, 54.2%, 73.6% and 78.7% in four samples from top to bottom, indicated a major methanogenesis pathway by acetoclastic methanogenesis in the methanogenic unit. The beta diversity indexes illustrated a more similar distribution of bacterial communities than that of methanogens between acidogenic unit and methanogenic unit. The differentiation of methanogenic community composition in two phases, as well as pH values and volatile fatty acid（VFA） concentrations confirmed the phase separation of the ITPAR. Overall, the results of this study demonstrated that the special designing of ITPAR maintained a sufficient number of methanogens, more diverse communities and stronger syntrophic associations among microorganisms, which made two phase anaerobic digestion of cellulosic materials more efficient.

Within the East Asian monsoon zone the change in oxygen isotope of Holocene stalagmite is mainly related to monsoon rain rather than to temperature. And carbon isotope can be taken as a comprehensive signal which contains the natural information and the information of anthropogenic activity. Isotopic analysis is also compared with the annual layer records.

The corundum - spinel castables were prepared by six kinds of tabular corundum, as aggregates, respective- ly, and their linear change rate on heating, apparent porosity, bulk density, cold modulus of rupture, coht crushing strength, hot modulus of rupture and thermal shock resistance were compared and studied. The results show that： 1） the six tabular corundum materials have similar main chemical composition but their physical properties vary for the different technical procedures which result in different properties of castables ; 2 ） the optimal properties of corundum - spinel castables corre- spotut to different tabular corundum types, so the corundum type shall be selected according to the application of the castables.

P2X receptors are a family of extracellular ATP-gated trimeric cation channels that is widely distributed in human tissues. Quite some drug candidates targeting P2X receptors have entered into preclinical or main phases of clinical trials, but many of them failed due to low subtype-selectivity or species differences in pharmacological activities between human and experimental animals. Here, we identified the distinct inhibitory efficacies of NF110, a competitive inhibitor, between the rat(rP2X3) and human(hP2X3) P2X3 receptors. We demonstrated that this difference is determined by two amino acids located in the dorsal fin(DF) domain of P2X3 receptors. As revealed by mutagenesis, metadynamics, and covalent modification, NF110-mediated rP2X3 inhibition may be through a filling in the cavity formed by the DF,left flipper(LF) and lower body(LB) to partially, rather than fully, occupy the ATP-binding ***, substitution of residues located in the DF and/or LF domains of the rP2X2 receptor, a NF110-insensitive subtype, with the equivalent amino acids of rP2X3, bestowed the sensitivity of rP2X2 to NF110. The critical roles of the DF and LF domains in channel gating of P2X and low conservativity in residue sequences of those two domains raise the possibility that small molecules differentially interacting with the residues of the DF and LF domains of different P2X receptors may modulate channel's activity in a subtype-selective manner. However, the possible species-specificity of P2X inhibitors/modulators makes it more complex when interpreting the preclinical data into clinical ***, our data provide new insights into the subtype-selectivity of competitive inhibitors and their distinct potencies in the human and experimental animals, both of which are extremely important in the drug discovery of P2X receptors.

To select the suitable plant species controlling Eupatorium adenophorum in hilly area, ecological adaptability, competitiveness and control efficacy of many replacement plants with economic value in Guizhou Province of China were studied. The results showed that the coverage of paspalum wetsfeteini and Dolichos lablab were 100% and 93%, which increased by 3.70 and 3.44 times compared with Lolium perenne, respectively; their relative crowding coefficient with E. adenophorum were 7.09 and 22.78, which increased by 2.43 and 7.80 times compared with L perenroe, respectively. Using excavation method, the control efficacies of replacement plants were 99.3 % and 96.9%, respectively, while the control efficacy of replacement plants using mowing method was lower than 66.4%. The overwintering rate of P. wetsfeteini in the following year was 95% ; its coverage was still 100% and its control efficacy against E. adenophorum remained over 99%. D. lablab was difficult to survive the winter in the north region beyond 26.2°N, so it could only be applied as annual replacement plant. The coverage of Setaria anceps, Cajanus cajan and other test plants were less than 90%, with poor control efficacy against E. adenophorum.

The piezoelectric bulk acoustic wave (BAW) impedance analysis method was employed to monitor in situ the proteinase-catalyzed hydrolyzation of casein and the effect of pesticide D-allethrin on the proteinase activity in the midgut of the spider Pardosa pseudoannulata, and the results obtained were verified by ultraviolet spectroscopy. The hydrolyzation was significantly increased in the presence of low-dose D-allethrin, whereas significantly inhibited in the presence of high-dose D-allethrin, and a correlation was found precisely between the enzyme activity reflected by the final frequency shift after the hydrolyzation and the concentration of D-allethrin, with a significant frequency response observed even at a 1.5×10-5 volume ratio of D-allethrin to distilled water. The present work may have presented a novel method feasible for study on the mechanism of excitability of spiders under low-dose D-allethrin pesticide and quick detection of proteinase activity.

海南岛周邻发育有4个重要的新生代沉积盆地,即莺歌海盆地、北部湾盆地、琼东南盆地和珠江口盆地珠三凹陷。根据最新的地球物理数据,重新厘定这些盆地的构造与沉积演化及其与海南岛陆上构造的关联。这些盆地发育NE和NW向断裂构造,但存在极大差异性。前者受红河哀牢山断裂构造影响,表现为张扭性的拉分盆地。而后三个盆地则总体表现为裂陷盆地,夹于江绍-博白断裂与丽水-南澳断裂南段之间。伸展始于古新世,具有四次裂陷作用,并发育NW向走滑伸展断层。晚期岩浆对沉积盆地具有一定改造作用,表现岩浆喷发、热流值高。我们厘定了这些NE向断裂在海南岛延伸,滨海断裂可能延至海南岛东南缘,并表现出明显的地震活动性,推断海南岛新生代构造演化与南海北部陆缘演化具有一致性。
