Topsoil soil organic carbon(SOC) data were collected from long-term Chinese agro-ecosystem experiments presented in 76 reports with measurements over 1977 and *** data set comprised 481 observations(135 rice paddies and 346 dry croplands) of SOC under different fertilization schemes at 70 experimental sites(28 rice paddies and 42 dry croplands).The data set covered 16 dominant soil types found in croplands across 23 provinces of China's *** fertilization schemes were grouped into six categories:N(inorganic nitrogen fertilizer only),NP(compound inorganic nitrogen and phosphorus fertilizers),NPK(compound inorganic nitrogen,phosphorus and potassium fertilizers),O(organic fertilizers only),OF(combined inorganic/organic fertilization) and Others(other unbalanced fertilizations such as P only,K only,P plus K and N plus K).Relative change in SOC content was analyzed,and rice paddies and dry croplands soils were *** was an overall temporal increase in topsoil SOC content,and relative annual change(RAC,g kg-1 yr-1) ranged -0.14-0.60(0.13 on average) for dry cropland soils and -0.12-0.70(0.19 on average) for rice *** content increase was higher in rice paddies than in dry *** increased across experimental sites,but was higher under organic fertilization and combined organic/inorganic fertilizations than chemical *** increase was higher under balanced chemical fertilizations with compound N,P and K fertilizers than unbalanced fertilizations such as N only,N plus P,and N plus *** effects of specific rational fertilizations on SOC increase persisted for 15 years in dry croplands and 20 years in rice paddies,although RAC values decreased generally as the experiment duration ***,the extension of rational fertilization in China's croplands may offer a technical option to enhance C sequestration potential and to sustain long-term crop productivity.

To the Editor:Toxic epidermal necrosis(TEN)is a severe dermal-mucous reaction characterized by rashes,blisters,and a generalized laxity of the epidermis.[1]Blockade of the programmed cell death protein 1(PD-1)/programmed cell death 1 ligand 1(PD-L1)pathway could activate and proliferate auto-reactive CD8+T-cells,which is a crucial step in *** efficacy of anti-CD19 chimeric antigen receptor-T(CAR-T)cells can be inhibited by activating the PD-1/PD-L1 pathway.[2]As a result,the combination of PD-1 blockade and CAR-T cell therapy would increase the functions of CAR-T cells.[3]This case report describes a patient with refractory diffuse large B-cell lymphoma(DLBCL)who had severe TEN after CAR-T cell therapy and PD-1 blockade.

目的:探讨链脲霉素诱导的糖尿病对烟酰胺腺嘌呤二核苷酸磷酸(NADPH)氧化酶的影响,测定运动的干预效应。方法:SD大鼠糖尿病建模成功1周后,检测心室和心房肌中NADPH氧化酶亚基的表达以及心血管紧张素Ⅱ的表达,测定8周的运动能否有效影响NADPH亚基以及血管紧张素Ⅱ的表达。结果:糖尿病导致心室肌NADPH氧化酶亚基p67^(Phox)和gp91^(phox)表达增加,而8周运动能够抑制两种亚基表达的增加。糖尿病心房肌p67^(phox)增加显著,运动抑制其增加。糖尿病心血管紧张素Ⅱ水平显著增加,运动降低血管紧张素Ⅱ的增加。结论:运动降低糖尿病大鼠心肌p67^(phox)和gp91^(phox)表达的增加,这可能是改善心内基质的机制之一,因此运动治疗和预防糖尿病心肌病的一个有效机制可能是通过抑制心肌氧化应激和降低血管紧张素Ⅱ的表达。

The Red Soil Hilly Region in South China, where there is a high capacity of carbon(C), and the land use and vegetation cover change greatly, is an important ecological area in the world, and has an important impact on the global carbon cycle and the seasonal fluctuation of atmospheric CO_2. To better evaluate the effects of reclamation systems in orchards converted from grasslands on soil carbon sequestration, we investigated soil organic carbon(SOC) content and stable C isotope(δ^(13)C)composition in three nectarine orchards at Yuchi Experimental Station in South China. Compared with the sloping clean tillage orchard and terraced clean tillage orchard, SOC content in the terraced orchard with grass cover was increased by 14.90% to 38.49%, and 7.40% to 15.33%, respectively. During the 14 years after orchard establishment, the soil organic matter sources influenced both δ^(13)C distribution with depth and carbon replacement. SOC turnover of the upper soil layer in the terraced orchard with grass cover(a mean 63.05% of replacement in the 20 cm after 14 years) was 1.59 and 1.41 times larger than that of the sloping clean tillage orchard and terraced clean tillage orchard under subtropical conditions, respectively. The equilibrium value of soil organic carbon in the three treatments ranged from 16.067 to 25.608 g/kg under the experimental conditions. The equilibrium value of soil organic carbon in the surface layer under grass cover was 54.801 t/hm^2, and the carbon sequestration potential was 24.695 1 t/hm^2.

目的:探讨跑台运动对海马细胞凋亡相关的空间学习能力的影响。方法:通过侧脑室注射链脲霉素(STZ)复制阿尔茨海默病大鼠模型(AD)。侧脑室注射STZ后3d,运动组大鼠在跑台上运动,每日30min,每天1次,共14d。8臂迷宫用于测试空间学习能力。Caspase-3免疫组织化学、Bax和Bcl-1蛋白质印迹用于测定细胞凋亡。结果:侧脑室注射STZ导致空间学习能力受损。8臂迷宫测试表明,与假手术组相比,AD组大鼠正确选择次数显著降低;与AD组相比,运动明显改善STZ诱导的正确选择次数的降低。STZ诱导的AD大鼠,海马Bcl-2表达降低,casepase-3和Bax表达增加。与AD组相比,跑台运动增加Bcl-2表达,降低casepase-3和Bax表达。结论:跑台运动改善神经退行性变疾病导致的记忆损害。

目的探索伴有焦虑症状双相抑郁患者认知功能与N-甲基-D-天冬氨酸受体2B亚基(glutamate iono-tropic receptor NMDA type subunit 2B,GRIN2B)基因启动子区各CpG位点甲基化水平的相关性。方法根据汉密尔顿焦虑量表(14-item Hamilton anxiety rating scale,HAMA)评分将31例双相抑郁患者分为焦虑组15例和非焦虑组16例,同期选取16名健康对照。采用蒙特利尔认知评估量表(Montreal cognitive assessment,MoCA)、数值广度测验(digital span test,DST)、连线测试A部分(trail making test A,TMT-A)、斯特鲁普色词测验(Stroop color and word test,SCWT)评估3组总体认知功能、注意力及执行控制、信息处理速度、执行功能等认知功能维度,采用Massarray质谱法检测所有受试者外周血GRIN2B基因启动子区各CpG位点的DNA甲基化水平。结果3组GRIN2B基因启动子区DNA甲基化水平差异性位点为CpG3、CpG5、CpG7、CpG10、CpG12(P<0.05),其中,焦虑组CpG12甲基化水平低于非焦虑组(36.23%±16.41%vs.50.20%±19.79%,P<0.05)。偏相关分析显示,焦虑组患者中较差的命名能力与GRIN2B基因CpG4低甲基化水平相关(r=0.670,P=0.034),较差的执行功能与CpG6低甲基化水平相关(r=0.926,P<0.001),较差的注意力与GRIN2B基因CpG8高甲基化水平相关(r=-0.810,P=0.025),较差的言语记忆与CpG9高甲基化水平相关(r=-0.810,P<0.001),较差的抽象能力与CpG10高甲基化水平相关(r=-0.756,P=0.011)。结论GRIN2B基因启动子区DNA甲基化水平与伴有焦虑症状双相抑郁患者认知功能损害可能有关联,与双相抑郁患者焦虑症状的产生也可能有关联。
