Nano-Fe_3O_4 can induce DNA single-strand breaks without significancy and can not induce micronuclei formation and percentage of apoptosis. Nano-Fe_3O_4 can aggravate the effect of CdCl2 on DNA single-strand breaks and chromosome damage in HepG2 cells. They showed synergistic effects on DNA single-strand breaks after the data were statistic analyzed.

结果发现CdCl2能引起DNA断裂损伤、微核率的增加和细胞凋亡率的增加；nano-Fe_3O_4能引起DNA断裂损伤增加，但无显著意义，未引起微核率和细胞凋亡率的增加；nano-Fe_3O_4能加重CdCl2的对细胞DNA断裂损伤和染色体损伤，且二者联合作用对DNA断裂损伤的结果经统计分析认为有协同作用。

paraquat is one kind of weedicide that comprehensive used all over the world ,for its little pollute to the environ accept a generally welcome .but the poisoning of paraquat have become a more and more severe problem,especially in developing county.the paraquat have a hypso-toxicity to human ,its mortality is 85%~95%.it show a multisystem injury to human body but the most serious injury of the paraqat to the viscera is lung .the mechanism of damnification is the great deal of super-oxygen ion procreant by paraquat in lung .at present the best technique to the diagonose of the paraquat poisoning to lung injury is ct.

百草枯是目前全世界范围内应用最广泛的除草剂，以其对环境的低污染性而受到广泛欢迎，但是百草枯中毒也随之成为一个越来越严重的题目，尤其是在发展中国家。百草枯对人体呈高毒性，死亡率约为85%~95%。百草枯中毒表现为多系统损伤，但是对人体脏器最主要的损伤是肺损伤，损伤机制主要为百草枯在肺组织内产生的大量超氧离子。目前对百草枯中毒致肺损伤的诊断最佳的方式是CT。

Analyze the synergetic damage of concrete by the mechod of thermodynamics and synergetics based on the characteristics of original damage consist in such brittle materials. Structural defects in rock and concrete and its influence on material damage under loads is summarized and auctorial opinions are put forward about these questions.

针对混凝土的力学性能在很大程度上取决于初始损伤的问题，而现有的损伤力学研究观点和理论都是基于某种假定对混凝土损伤演化进行研究，很难从本质上对混凝土损伤演化过程进行描述。

So far, the convincible mechanism involved in the development and progress of the inflammatory responses after SCI is not quite clear.

在脑损伤的研究中发现，脑损伤后多种促炎性细胞因子、趋化因子明显上调，加剧损伤后炎症反应，在继发性脑损伤的病理过程中起重要作用。

(1) Oxidative/antioxidative reactions, inflammatory reactions, apoptosis in lung are involved in the pathogenesis of HILI;(2) ABX, rHuEPO have protective effects on HILI respectively;(3) Hyperoxia can increase VILI in rats, but has little effects with low tidal volume mechanical ventilation.

结论(1)氧化抗氧化失衡，炎症反应，肺内细胞凋亡参与了高氧所致成年大鼠肺损伤的过程；(2)ABX通过抗炎、抗氧化、抑制细胞凋亡作用对成年大鼠高氧肺损伤具有保护作用；rHuEPO通过抗炎、抗氧化、抑制细胞凋亡及一定程度的抗纤维化作用对成年大鼠高氧肺损伤具有保护作用；(3)高浓度氧能明显加重大鼠通气机所致肺损伤，而高浓度氧对小潮气量通气影响较小。

For example, MI behaved most sensitive to heart state when spontaneous respiration inhibited with respiration machine; FD could manifest heart healthy level, which reduced sharply sooner after acute injury but remained almost steady afterwards; the parameters of Poincare dissert-dot plot and HRV could accurately distinguish the state change before and after ligaturing; the HF-ECG excelled in not only revealing injury degree but also locating injury position.

例如，交互信息对自主呼吸被接呼吸机抑制后的状态敏感，分维具有表征心脏健康状况潜力的特性，在急性损伤后明显减少，但不随损伤的时间延续而变化；心率变异性参数和散点图可以灵敏地区分出急性损伤前和损伤后的状态；而高频心电在表征心脏损伤和定位方面独具特色。

EXPERIMENT 1 Objective To study the regularity of the injury of the mice learning and memory ability, after the whole brain irradiation. Method After anaesthetized with thiopentone, the whole brain of Kunming mice was irradiated with 10MeV electron beam. Mouse learning and memory ability were measured with step down method on the first, second, third, fourth, fifth, fourteenth, twenty-eighth, fifty-sixth and eighty-fourth day after the irradiation.

随着现代放疗技术及计算机、分子生物学等相关学科的快速发展，肿瘤疗效逐步提高，脑等晚反应组织的放射损伤越来越受重视，因而有必要采用动物实验及分子病理学手段，深入研究放射性脑损伤的发病机理和早期症状，以及活血化瘀中药的防治作用，为此我们设计并完成了学习记忆力放射损伤规律、脑室管膜下区细胞凋亡及相关基因表达、中药防治放射性脑损伤及分子机理三个实验，介绍如下：实验一目的研究照射后鼠学习记忆力损伤变化规律。

Based on the statistical damage evolution equation considering stress damage threshold and the multiple rheological model of gypsum breccias, the damage rheological constitutional model is established from hypothesis of strain equivalence. The calculated results of the model agree well with creep test results.

在Kachanov提出的一维蠕变损伤演化方程的基础上，建立了同时考虑瞬时损伤和蠕变损伤的流变本构模型，理论值与试验值基本一致，验证了提出的蠕变损伤演化方程是正确的，所建的损伤流变模型能够较好地描述石膏角砾岩的加速蠕变阶段。

The rock damage model and the damage-coupling model suited to analyze the whole process of water jet breaking rock were established with continuum damage mechanics and micro damage mechanics.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
