Results Oxygen metabolism abnormality was found after trauma, and it was correlated with ISS, RTS, injured organ or region and number of injured organs, shock, systemic inflammatory response syndrome and respiratory complications. It was more intense in the patients with MODS. There was marked difference in the ratio of change in oxygen metabolism between MODS and NMODS groups. Oxygen deficiency metabolic variables tended to deteriorate in the nonsurvival group. More marked changes in metabolic variables indicated severer organ dysfunction, reaching their peak values before death.

结果 氧代谢水平在创伤后即发生异常，与创伤严重度评分、RTS、损伤器官部位与数量、低血容量性休克、全身炎症反应综合征以及是否并发呼吸系统合并症等有关；并发MODS患者氧代谢水平变化更为明显，与轻伤对照组和NMODS组比较相关氧代谢比值改变差异均有显著性；死亡组乏氧代谢指标常呈持续恶化趋势，其代谢水平改变越显著，预示器官功能损害程度越严重，往往于死亡前达到峰值。

Mol〓. As the result, some sensitizers have obviously sensitive effect, the ratio of / in photostationary state was change, We designed two methods, One of them is that isomers were synthesized, then we obtained the mixtures of isomers via photoisomerization.

本论文试图由两种方法获得-O-烃基-α-氧代环十二酮肟，一种是由体的肟通过化学合成得到体的O-烃基-α-氧代环十二酮肟，再通过光化学反应得到其体；另一种是由-α-氧代环十二酮肟，通过光化学异构合成体，再由体肟化学合成得到-O-烃基-α-氧代环十二酮肟。

The purpose of this study is to screen microorganisms with growth inhibition against plant fungal pathogens. The plate-dilution method was used to isolate the bacteria from salt marshes at Dafeng, Jiangsu. The antifungal activity of the bacterial broth filtrates against 5 phytopathogens was determined using mycelial disk method. The antifungal compositions of four active bacteria were analyzed primarily with chromatography techniques. Two hundred and thirty-five aerobic (92) and anaerobic (143) bacterial strains have been isolated from the coast salt marsh and sixty-five strains, of which 39 are aerobic and 26 are anaerobic showed greater than 30% of inhibition rate against the growth of at least one of the phytopathogenic fungi on petri dish.
