Anaerobic ammonium oxidation(ANAMMOX)is a new process of nitrogen conversion that has prospect most currently.The AN- AMMOX process offers great opportunities to remove ammonia from wastewater without the addition of an external carbon source and with con- siderable less aeration costs in comparison with classical methods.ANAMMOX is a biologically mediated process.Three bacteria are identi- fied responsible for the process as new deep-branching planctomycete:Brocadia,Kuenenia and Scalindua.Described it to separate and the method,biochemistry path,the ecosystem physiology characteristic for authenticate and distribute.

To investigate the relationship between diabetic macular edema (DME) and serum E-selectin level.
●METHODS: Totally 90 patients with diabetic retinopathy in our hospital from October 2009 to October 2013 were observed. Retrospective analysis of the correlation between macular edema degree and serum soluble E -selectin ( sE - sel ). Ninety patients with diabetic retinopathy were divided into two groups: DME group and non - DME group. The level of sE - sel and microalbuminuria (MA) of two groups were determined and compared.
●RESULTS: There was significant difference in MA, sE-sel levels of groups ( P < 0. 05). The value of diabetic retinopathy patients with sE - sel and MA, FBG were positively correlated ( r = 0. 728, P < 0. 05; r = 0. 651, P <0. 05).
●CONCLUSlON: Elevated levels of sE-sel is a risk factor for diabetic macular edema, and sE-sel was involved in the pathogenesis of diabetic microangiopathy.

BACKGROUND:Due to the differences of sport events and individual metabolic characteristics of athletes, it is difficult to establish uniform biological indexes for training monitoring. Current individual evaluation is a longitudinal analysis relying on experience or numerical variation width, which is less objective.OBJECTIVE: To explore the individual function assessment and monitoring by monitoring blood biochemical indexes and brain function indexes in elite gymnasts, in order to accurately reflect the body changes resulting from training loads. METHODS:Thirty gymnasts from the Chinese national gymnastics team preparing for London Olympic Games were enroled in this study and monitored from the last winter training until the London Olympic Games. The blood biochemical indicators and brain function indicators were measured and assessed individually according to according to the principle of quality control (alert value=mean±SD, and controled variable=mean±2SD). RESULTS AND CONCLUSION:Under the relatively uniform test conditions, it is feasible to individualy assess the blood biochemical and brain function indexes of elite gymnasts in accordance with the principle of quality control, which is more accurate and objective to reflect the body changes under training load and the current state of athletes. In addition, the combined monitoring of blood biochemical indexes and brain function indexes is more comprehensive to evaluate the body function and status of elite gymnasts.

Plant insect-resistantgenetic engineering hasopened a new way to prevent and cure against the insect pest incrop and wood productions. With the progresses instudies, many insect-resistantgeneswere cloned and characterized. The classification of most insect-resistantgenes from plant, the functionalmechanism and the applications of theplantinsect-resistantgenes, the problems and prospectsforusing the plant insect-resistant genes in genetic engineering was described.

With development of wide-host-range vector systems,Tn5 transposon and its derivative vectors have been widely applied to genetic research of gram-negative bacteria.The applications of Tn5 transposon mutagenesis technology to genetic researches of bacteria were briefly discussed,including researches on biological control mechanisms of biocontrol bacteria,identification of bacterial essential genes,discovering virulence genes of bacterial pathogens,characterization of metabolism regulatory genes and genetic improvements of bacteria.
