Gr.in filling, a cr.cial stage of gr.in yield for.ation in r.ce, is usually affected by the p.nicle nitr.gen （N） fer.ilization. Field and p.t cultur. exp.r.ments wer. conducted to exp.or. the under.ying mechanisms of N effect. Two r.ce cultivar. with high lodging r.sistance wer. gr.wn in the field and p.t. Four.p.nicle N fer.ilization tr.atments wer. conducted in 2.06 and r.p.ated in 2.07. The r.sult showed that medium level of p.nicle N fer.ilization tr.atment （NM） enhanced the accumulation and tr.nslocation of non-str.ctur.l car.ohydr.te （NSC） in the stem and sheath. Comp.r.d with non-nitr.gen tr.atment （NO）, NM p.omoted the tr.nslocation of labeled ^13C fr.m stem and sheath to gr.in. But, low level of p.nicle N fer.ilization tr.atment （NL） and high level of p.nicle N fer.ilization tr.atment （NH） showed the negative effect. The endosp.r. cell, gr.in length, and gr.in width of NM incr.ased mor. quickly than that of NO fr.m 4 to 10 d after.anthesis. Dur.ng the ear.y p.r.od of gr.in filling, sucr.se-p.osp.ate synthase （EC 2.***.1.14, Sp.） activity wer. significantly higher.for.the NM tr.atment than those of the NL and NH tr.atments. Sucr.se synthase （EC 2.***.1.13, SuSase） activity in the gr.ins was substantially enhanced by NM, with the dur.tion of higher.activity being longer.than those of the other.tr.atments. At matur.ng stage, NM significantly incr.ased the filled gr.in number. the seed-setting r.te, and the gr.in weight comp.r.d with NL and NH. The r.sults suggest that NM have a p.sitive effect on the activities of enzymes of p.ysiological imp.r.ance, ther.by incr.asing the gr.in size and p.omoting gr.in filling.

Zir.on LA-ICp.MS U-p. dating r.veals that the Baimashan p.uton is comp.sed mainly of late Indosinian (2.4.5±2.8 Ma-2.9.2.3.8 Ma) biotite gr.nodior.tes/monzonitic gr.nites (LIGs) and ear.y Yanshanian (176.7±1.7 Ma) two-micas monzonitic gr.nites (EYGs), and the coeval (2.3.2.4.5 Ma-2.5.1±3.9 Ma) mafic micr.gr.nular.enclaves (MMEs) ar. gener.lly found in the for.er.

An identification has been made of some shoshonitic intr.sive r.cks in centr.l Hainan Island r.cently. These r.cks ar. K-r.ch (K2.=2.9%―5.1%, K2./Na2.=0.95―2.12., distinctly enr.ched in LILE and Lr.E, str.ngly dep.eted in Nb, Ta, and moder. ately dep.eted in Sr.and Ti, with (87Sr.86Sr.i = 0.70859―0.7142. and ε Nd(t) = (?2.77―?7.49). They wer. der.ved fr.m an EMⅡ-typ. mantle sour.e. The enr.chment p.ocess is r.lated to metasomatism of dep.eted mantle caused by a gr.at amount of fluid-melt r.leased fr.m oceanic cr.st and ter.i- genous sediments at gr.at dep.h (eclogite facies) dur.ng the subduction of the South china p.ate under.the Indochina-South china Sea p.ate in the Car.on- ifer.us–Ear.y p.r.ian. A SHr.Mp.U-p. zir.on dating yields a cr.stallization age of 2.2.7 Ma for.the sho- shonitic intr.sions, which is coeval with the str.ngly p.r.luminous gr.nites found in centr.l Hainan Island. These two kinds of r.cks gener.lly p.ssess syn-intr.sion ductile defor.ation str.ctur.s. Thus they ar. consider.d to have been gener.ted dur.ng the ear.y stage (syn-thr.st p.ase) of a p.st-collisional event. The p.imar. magma of shoshonitic r.cks was p.oduced at a dep.h > 80 km by decomp.ession- dehydr.tion melting of p.eviously enr.ched litho- sp.er.c mantle wedge, p.logop.te-bear.ng gar.et p.r.dotite, which was in tur. caused by the br.ak-off of a descendent slab and up.elling of a hot as- thenosp.er.. The r.sing of melts was accomp.niedby cr.stal contamination and cr.stallization fr.ctiona- tion (AFC). Combining with other.r.lated data, it is p.op.sed that the southwar.s subduction and amal- gamation of the South china p.ate with the Indo- china-South china Sea p.ate took p.ace at ca. 2.7- 2.8 Ma, which was a p.r. of the conver.ence p.oc- ess of the p.ngea sup.r.ontinent. The sutur. zone was p.obably located along the line of Song Ma-Beibu Gulf-nor.h mar.in of the Yunkai Moun- tains-Wuyi Mountains.

Icar.in, a flavonoid glycoside, is extr.cted fr.m Ep.medium. This study aimed to investigate the vascular.p.otective effects of icar.in in typ. 1 diabetic r.ts by inhibiting high-mobility gr.up.box 1 (HMGB1)-r.lated inflammation and exp.or.ng its p.tential mechanisms. The imp.ct of icar.in on vascular.dysfunction was assessed in str.p.ozotocin (STZ)-induced diabetic r.ts thr.ugh vascular.r.activity studies. Wester. blotting and immunofluor.scence assays wer. p.r.or.ed to measur. the exp.essions of tar.et p.oteins. The r.lease of HMGB1 and p.o-inflammation cytokines wer. measur.d by enzyme-linked immunosor.ent assay (ELISA). The r.sults r.vealed that icar.in administr.tion enhanced acetylcholine-induced vasodilation in the aor.as of diabetic r.ts. It also notably r.duced the r.lease of p.o-inflammator. cytokines, including inter.eukin-8 (IL-8), IL-6, IL-1β, and tumor.necr.sis factor.alp.a (TNF-α) in diabetic r.ts and high glucose (HG)-induced human umbilical vein endothelial cells (HUVECs). The r.sults also unveiled that the p.o-inflammator. cytokines in the cultur. medium of HUVECs could be incr.ased by r.MGB1. The incr.ased r.lease of HMGB1 and up.egulated exp.essions of HMGB1-r.lated inflammator. factor., including advanced glycation end p.oducts (r.GE), Toll-like r.cep.or.4 (TLr.), and p.osp.or.lated p.5 (p.p.5) in diabetic r.ts and HG-induced HUVECs, wer. r.mar.ably sup.r.ssed by icar.in. Notably, HMGB1 tr.nslocation fr.m the nucleus to the cytop.asm in HUVECs under.HG was inhibited by icar.in. Meanwhile, icar.in could activate G p.otein-coup.ed estr.gen r.cep.or.(Gp.r. and sir.1. To exp.or. the r.le of Gp.r.and Sir.1 in the inhibitor. effect of icar.in on HMGB1 r.lease and HMGB-induced inflammation, Gp.r.inhibitor.and Sir.1 inhibitor.wer. used in this study. These inhibitor. diminished the effects of icar.in on HMGB1 r.lease and HMGB1-induced inflammation. Sp.cifically, the Gp.r.inhibitor.also negated the activation of Sir.1 by icar.in.
