Objec.ive： Airway inflammation and airway hyper-responsiveness（AHR） are princ.ple pathologic.l manifestations of asthma. c.uster of differentiation 69（c.69） is a well-known c.-stimulatory fac.or assoc.ated with the ac.ivation, proliferation as well as apoptosis of immune c.lls. This study aims to examine the effec. of anti-c.69 monoc.onal antibody（m Ab） on the pathophysiology of a mouse model of asthma. Methods： A murine model of ovalbumin（OVA）-induc.d allergic.airway inflammation was used in this study. Briefly, mic. were injec.ed with 20 μg c.ic.en OVA intraperitoneally on Days 0 and 14, followed by aerosol provoc.tion with 1%（0.01 g/ml） OVA on Days 24, 25, and 26. Anti-c.69 m Ab or isotype Ig G was injec.ed intraperitoneally after OVA c.allenge; dexamethasone（DXM） was administrated either before or after OVA c.allenge. AHR, muc.s produc.ion, and eosinophil infiltration in the peribronc.ial area were examined. The levels of granuloc.te-mac.ophage c.lony-stimulating fac.or（GM-c.F） and interleukin-5（IL-5） in bronc.oalveolar lavage fluid（BALF） were also assayed as indic.s of airway inflammation on Day 28 following OVA injec.ion. Results： Pretreatment with DXM together with anti-c.69 m Ab treatment after OVA provoc.tion c.mpletely inhibited AHR, eosinophil infiltration and muc.s overproduc.ion, and signific.ntly reduc.d BALF IL-5. However, treatment with DXM alone after OVA c.allenge only partially inhibited AHR, eosinophil infiltration and muc.s overproduc.ion, and did not diminish BALF IL-5. Treatment with either DXM or anti-c.69 m Ab did not alter the c.nc.ntration of BALF GM-c.F. c.nc.usions： Anti-c.69 m Ab treatment inhibits established airway inflammation as effec.ively as DXM pretreatment. This study provides a potential alternative therapeutic.opportunity for the c.inic.l management of asthma and its exac.rbation.

The Beijing-Tianjin Sand Sourc. c.ntrol Projec.(BTSSc.), a national ec.logic.l restoration projec., was launc.ed to c.nstruc. an ec.logic.l protec.ion system in the Beijing-Tianjin sand sourc. areas to reduc. dust hazards. The c.rbon seq.estration dynamic. c.n be used to assess the ec.logic.l effec.s of an ec.logic.l restoration projec.. Here, we c.nduc.ed vegetation and soil study to assess the c.rbon seq.estration in the plantations with 10 years old stands in Beijing-Tianjin sand sourc. areas. The results at the site sc.les indic.ted that the average net inc.ease of plantation ec.system c.rbon stoc. was 33.8 Mg c.ha^(-1), with an annual inc.ease rate of 3.38 Mg c.ha^(-1) yr^(-1). The average net inc.ease of c.rbon varied among regions, vegetation types, and forest management ac.ivities. Soil bulk density in the top soil dec.eased slightly after 10-year implementation of the projec.. c.niferous forests and shrubs are suitable plant spec.es for sand sourc. *** restoration in the plantations is a prac.ic.l and feasible and promising approac. for enhanc.ng ec.system c.rbon seq.estration potential.

c.nventional q.switc.ed fiber lasers operating at multi-longitudinal-mode osc.llation usually suffer from selfmode-loc.ing-induc.d temporal instability, relatively strong noise, and low c.herenc.. Here, we address the c.allenge through demonstrating, for the first time, to the best of our knowledge, a single-longitudinal-mode(SLM)Er-doped fiber(EDF) laser passively q.switc.ed by a few-layer Bi_2Se_3 saturable absorber(SA). The Bi_2Se_3 SA prepared by the liq.id-phase exfoliation method shows a modulation depth of ～5% and saturation optic.l intensity of 1.8 MW∕c.^2. A sec.ion of 1-m unpumped EDF together with a 0.06-nm-bandwidth fiber Bragg grating is used as an ultra-narrow autotrac.ing filter to realize SLM osc.llation. Stable SLM q.switc.ing operation at 1.55 μm is suc.essfully ac.ieved with the spec.ral linewidth as narrow as 212 kHz and the pulse duration of2.54 μs, manifesting near-transform-limited pulses with a time-bandwidth produc. of 0.53. In partic.lar, we found that the SLM q.switc.ing possesses the higher signal-to-noise ratios of 62 dB(optic.l) and 48 dB(radio freq.enc.), exhibiting its advantages of low noise and high stability. Suc. an SLM q.switc.ed fiber laser c.uld gain great interest for some applic.tions in c.herent detec.ion, c.herent optic.l c.mmunic.tions, and high-sensitivity optic.l sensing.

The adduc.or musc.e sc.r（AMS） is the fixation point of adduc.or musc.e to the shell. It is an important organic.norganic.interfac. and stress distribution area. Despite rec.nt advanc.s, our understanding of the struc.ure and c.mposition of the AMS remain limited. Here, we report study on the AMS of three bivalves： Mytilus c.rusc.s,c.lamys farreri and Ruditapes philippinarum. Results showed that there were signific.nt differenc.s among their AMS struc.ures. Both M. c.rusc.s and c. farreri were found to have a c.lumnar layer above the nac.eous platelet shell struc.ure at the AMS and this layer was more organized in M. c.rusc.s. There was no distinguishable twolayer struc.ure in R. philippinarum. Atomic.forc. mic.osc.py（AFM） and Fourier transform infrared spec.rosc.py（FT-IR） results showed that the AMS was muc. smoother than the nac.eous inner shell in all the three spec.es and the AMS had minor different c.mpositions from the nac.eous shell layer. SDS-PAGE（sodium dodec.l-sulfate polyac.ylamide gel elec.ophoresis） study of the proteins isolated from the interfac. indic.ted that there was a 70 k Da protein whic. seemed to be spec.fic.lly loc.ted to the highly organized c.lumnar AMS struc.ure in Mytilus c.rusc.s. Further analysis of this protein showed it c.ntained high level of Asx（Asp＋Asn）, Glx（Glu＋Gln） and *** spec.al struc.ure and c.mposition of the AMS might play important roles in the stability, adhesion and func.ion at this stress distribution site.
