An oxygen-tolerant denitrifying strain designated as H1 was screened by the procedures of shallow shaking and continuous aeration cultures.With the aid of an nnrS-gfp fusion responsive to nitric oxide (NO)and acetylene inhibition-GC procedure,it was shown that strain H1 was able to produce NO and N_2O but not N_2 under denitrifying conditions.Denitrifying processes were thus determined as NO_3~-→NO_2~-→NO→N_2O,with N_2O as the end product.Strain H1 could denitrify under shallow shaking conditions as well as in the initial atmospheric oxygen concentration ranging from 0~21%.Denitrification processed normally under continuous aeration at the rate of 2 L air per min in a 150 mL medium,but stopped under high aeration rate as 5 L air per min.16S rRNA gene sequence revealed that strain H1 shared 98% similarity to its closet relative Ralstonia taiwanensis,the genus where denitrifying bacteria are frequently found.

AIM:To study the effects of adiponectin on H 2 O2-induced cell injury and tau hyperphosphorylation in human neuroblastoma SH-SY5Y cells.METHODS:Cell viability was determined by MTT assay .H2 O2-induced cell in-jury and morphological changes in the SH-SY5Y cells with or without adiponectin treatment were observed .The level of tau phosphorylation as well as the activities of protein phosphatase 2A (PP2A) and of glycogen synthase kinase-3β(GSK-3β) were examined by Western blotting . RESULTS: Adiponectin significantly attenuated H 2 O2-induced cell injury (P<0.01).Adiponectin upregulated the activity of PP2A and decreased phosphorylation levels of tau under the stimula-tion with H2O2(P<0.01).Okadaic acid, a specific inhibitor of PP2A, blocked the protective effects of adiponectin (P<0.01).Adiponectin increased the phosphorylation level of GSK-3βat Ser9 site under H2O2stimulation (P<0.01).CON-CLUSION:Adiponectin protects SH-SY5Y cells against H2O2-induced cell injury and decreases tau hyperphosphorylation by activating PP2A and inactivating GSK-3β.

Objective To analyze the epidemiological characteristics of the imported malaria cases in 20 counties at the bor?der region of Yunnan Province from 2012 to 2014,so as to provide the evidence?based proof for adjusting the strategies in the elimination stage. Methods The malaria epidemic data of the 20 border counties in Yunnan Province from 2012 to 2014 were collected and analyzed by using Microsoft Excel 2010. Results From 2012 to 2014,a total of 1 558 malaria cases were report?ed in the 20 border counties in Yunnan Province,among which,1 336 were imported cases,accounting for 85.75%(1 336/1 558),and 222 were indigenous cases,accounting for 14.25%(222/1 558). The number of the imported cases in the above years took up 80.00%(544/680),89.10%(425/477)and 91.52%(367/401)of the total reported cases in the whole year,re?spectively. Among all the 1 336 imported cases,1 045(78.22%)were infected with Plasmodium vivax,284(21.26%)were in?fected with P. falciparum,3 were infected with P. malariae,3 were mixed infection and 1 was an unclassified case;2 patients died. And 95.58%of the cases were mainly infected in Myanmar(1 277 cases). Young and middle?aged adult of 20-40 years who worked overseas were the predominant(802 cases,60.03%)and most of the cases occurred from April to June of the year (679 cases,50.82%). Those cases mainly distributed in Tengchong(459 cases),Ruili(366 cases),Yingjiang(191 cases)and Mangshi(78 cases). Conclusions The epidemic situation of imported malaria is serious in the border region of Yunnan Prov?ince. Therefore,the surveillance system of malaria control needs to be well planned and managed to ensure timely case detection and prompt response at the elimination and post?elimination stage.
