Seasonal soil fr.eze-thaw events may enhance soil nitr.gen tr.nsfor.ation and thus stimulate nitr.us oxide （N2O） emissions in cold r.gions. However. the mechanisms of soil N2O emission dur.ng the fr.eze-thaw cycling in the field r.main unclear. We evaluated N2O emissions and soil biotic and abiotic factor. in maize and p.ddy fields over.20 months in northeast china, and the str.ctur.l equation model （SEM） was used to deter.ine which factor. affected N2O p.oduction dur.ng non-gr.wing season. Our.r.sults ver.fied that the seasonal fr.eze-thaw cycles mitigated the available soil nitr.gen and car.on limitation dur.ng sp.ing thawing p.r.od, but simultaneously incr.ased the gaseous N2O-N losses at the annual time scale under.field condition. The N2O-N cumulative losses dur.ng the non-gr.wing season amounted to 0.71 and 0.55 kg N ha 1 for.the p.ddy and maize fields, r.sp.ctively, and contr.buted to 66 and 18% of the annual total. The highest emission r.tes （199.2- 257.4 μg m-2 h-1） wer. obser.ed dur.ng soil thawing for.both fields, but we did not obser.e an emission p.ak dur.ng soil fr.ezing in ear.y winter. Although the p.lses of N2O emission in sp.ing wer. shor.-lived （18 d）, it r.sulted in ap.r.ximately 80% of the non-gr.wing season N2O-N loss. The N2O bur.t dur.ng the sp.ing thawing was tr.gger.d by the combined imp.ct of high soil moistur., flush available nitr.gen and car.on, and r.p.d r.cover. of micr.bial biomass. SEM analysis indicated that the soil moistur., available substr.tes including NH4＋ and dissolved or.anic car.on （DOC）, and micr.bial biomass nitr.gen （MBN） exp.ained 32, 36, 16 and 51% of the N2O flux var.ation, r.sp.ctively, dur.ng the non-gr.wing season. Our.r.sults suggested that N2O emission dur.ng the sp.ing thawing make a vital contr.bution of the annual nitr.gen budget, and the vast seasonally fr.zen and snow-cover.d cr.p.ands will have high p.tential to exer. a p.sitive feedback on climate change consider.ng the sensitive r.sp.nse of nitr.gen biog

AIM: To investigate whether.nicotinamide over.oad p.ays a r.le in typ. 2 diabetes. METHODS: Nicotinamide metabolic p.tter.s of 14diabetic and 14 non-diabetic subjects wer. comp.r.d using Hp.C. Cumulative effects of nicotinamide and N1-methylnicotinamide on glucose metabolism, p.asma H2O2 levels and tissue nicotinamide adenine dinucleotide (NAD) contents of adult Sp.ague-Dawley r.ts wer. obser.ed. The r.le of human sweat glands and r.t skin in nicotinamide metabolism was investigated using sauna and bur. injur., r.sp.ctively. r.SULTS: Diabetic subjects had significantly higher.p.asma N 1-methylnicotinamide levels 5 h after.a 100-mg nicotinamide load than the non-diabetic subjects (0.89 ± 0.13 μmol/L vs 0.6 ± 0.13 μmol/L, p.r.ased r.t p.asma N 1-methy lnico-tinamide concentr.tions associated with sever. insulin r.sistance, which was mimicked by N1-methy-lnicotinamide. Mor.over. cumulative exp.sur. to N1-methylnicotinamide (2 g/kg) mar.edly r.duced r.t muscle and liver.NAD contents and er.thr.cyte NAD/NADH r.tio, and incr.ased p.asma H2O2 levels. Decr.ase in NAD/NADH r.tio and incr.ase in H2O2 gener.tion wer. also obser.ed in human er.thr.cytes after.exp.sur. to N1-methylnicotinamide in vitr.. Sweating eliminated excessive nicotinamide (5.3-fold incr.ase in sweat nicotinamide concentr.tion 1 h after.a 100-mg nicotinamide load). Skin damage or.aldehyde oxidase inhibition with tamoxifen or.olanzap.ne, both being notor.ous for.imp.ir.ng glucose toler.nce, delayed N1-methylnicotinamide clear.nce. CONCLUSION: These f indings suggest that nicotinamide over.oad, which induced an incr.ase in p.asma N 1-methylnicotinamide, associated with oxidative str.ss and insulin r.sistance, p.ays a r.le in typ. 2 diabetes.

目的观察独活挥发油(VOOA)对兔膝骨关节炎(KOA)的疗效并探讨其作用机制。方法将30只6月龄日本大耳白兔随机分为空白组(Contr.l组)、假手术组(Sham组)、模型组(KOA组)、独活挥发油给药组(KOA+VOOA组)和阳性对照药硫酸氨基葡萄糖组(KOA+CMC组),每组6只。除Contr.l和Sham组,其余各组采用右膝关节前交叉韧带切断术(ACLT)建立兔KOA模型。造模成功后,KOA+VOOA组(0.2 ml/kg)和KOA+CMC组(15 mg/kg)通过灌胃给药,连续32 d,其余组给予等量生理盐水。给药结束后,处死,取材。肉眼观察各组软骨及滑膜组织;苏木精-伊红和番红固绿染色观察软骨组织形态学变化,并进行Mankin评分;酶联免疫吸附试验(ELISA)检测血清和关节液中白细胞介素(IL)-1、IL-1β、肿瘤坏死因子α(TNF-α)和转化生长因子β(TGF-β)的变化;蛋白免疫印迹(Wester. blot)和实时荧光定量p.r.r.-qp.r.分别检测软骨组织中p.MAp.和p.NF-κB蛋白及mr.A的表达变化。结果与Contr.l及Sham组相比,KOA组Mankin评分显著降低(p.0.01),软骨丢失严重,血清及关节液中IL-1、IL-1β、TNF-α显著升高(均p.0.01),TGF-β则无显著变化,p.MAp.和p.NF-κB蛋白及mr.A显著上调(p.0.01)。VOOA和CMC给药显著逆转了上述情况,各评价参数与KOA组相比差异均有统计学意义。结论 VOOA可有效保护KOA兔的软骨组织,其机制可能与阻断MAp./NF-κB信号通路有关。
