The results showed that plant height increasing speed was significantly slow at the former and middle stage when K level was above 180 kg/hm2.On the contrary,the height of case-hardened plant improved markedly.When the K level was above 135 kg/hm2,the stem girth and maximal leaf area differed significantly as compared with CK,so did LAI.Yield and product value per unit area took the first place when 180 kg/hm2 potassium was used.Average price and proportion of middle and first grade tobacco leaf of 225 kg/hm2 potassium treatment were the highest as compared with other treatments and CK.Four economic characters of the two treatments differed at obvious significant level as companied with CK.The total sugar and K2O were increased,nicotine, total N,protein and Cl- were decreased with increased K levels.The potassium lacked symptom was alleviated with increased K levels,no symptoms was observed when 180 kg/hm2 potassium was used,the degree of weather infected fleck was decreased when the K levels was increased.

结果表明，在烟株生长前中期，当施钾量达到180 kg/hm2以上时，株高增长显著变慢，而定型株高则显著增高；茎围和最大叶的面积在施用135 kg/hm2以上的处理与CK之间的差异性达到极显著水平，叶面积指数也存在显著差异；单位面积产量和产值以施用180 kg/hm2的处理居首位，中上等烟比例和均价以施用225kg/hm2的处理最高，这两种处理的以上4个经济性状与CK之间存在极显著性差异；烟叶中的总糖和K2O含量随施钾量的增加而上升，烟碱、总氮、蛋白质和C-含量则下降；缺钾症状随施钾量增加而减轻，至施用180kg/hm2时已无缺钾症状；烟叶气候斑的发生程度也随施钾水平的提高而减轻。

The comparisons of biochemistry between OP and OR rats The differences between OP and OR rats included not only body weight, but lipids metabolism and insulin sensitivity as well, characterized with insulin resistance, increasing in serum free fatty acids and ketone body, and hepatic TC and TG in OP rats. However, no significant differences were observed in serum TG, TC, LDL, HDL and fasting glucose between OP and OR rats.⑶Comparisons of metabolites in serum, urine and liver tissue between OP and OR rats①There were significant differences in amino acids concentration between OP and OR rats,especially in liver tissue, such as high concentrations in ketogenic and glucogenic amino acids in OP rats, suggesting differences in amino acids metabolism;② The different metabolites between OP and OR rats included increasing of various saturated fatty acids and decreasing of polyunsaturated fatty acids in OP rats;③The urinary metabolites analysis indicated that different structure or metabolism of gut microflora might exist between the two phenotypes, which probably influenced the regulation of body weight gain;④The end-products of catecholamines in urine and intermediates of krebs cycle in serum in OP rats were all up-regulated, suggesting that the activity of sympatheic nervous system and energy metabolism was higher in OP rats than OR rats.

胰岛素耐受实验和胰岛素敏感指数表明OP动物的胰岛素敏感性较OR动物下降，而OP大鼠血清中游离脂肪酸、酮体、肝脏总胆固醇和甘油三酯水平显著升高；但是，OP与OR大鼠血清中总胆固醇、甘油三酯、低密度脂蛋白、高密度脂蛋白和空腹血糖等的水平并无显著性差异；⑶肥胖易感与肥胖抵抗大鼠血清、尿液和肝脏组织提取物中代谢物的比较研究表明：①OP与OR大鼠的血清、尿液和肝组织提取物中多种氨基酸的含量存在显著差异，并以肝组织中的差异氨基酸数量为最多，包括各种生酮和生糖氨基酸水平在OP组的升高，说明氨基酸代谢的差异是两种体重表型大鼠之间存在的重要差异特征之一；②OP与OR动物肝脏和血清差异代谢物中包含多种饱和长链脂肪酸的升高如十四烷酸、十六烷酸、硬脂酸等和多不饱和脂肪酸的下降如亚油酸和花生四烯酸，说明两种体重表型动物的肝脏脂肪酸代谢存在明显差异；③长期高脂饮食喂养后，动物的尿液代谢物分析表明OP与OR动物体内的肠道菌群结构存在差异，这些菌群上的差别可能在动物体重增长的调节上产生影响；④与OR动物相比，OP动物尿液代谢物中儿茶酚胺类递质的代谢终产物如高香草酸、扁桃酸和4-羟基苯乙酸明显升高。

by applying psychological measurement methods, the author compared volition quality between short track speed skaters with difference sports performances and genders in order to gain an insight into if there is a difference in volition quality between them, and revealed the following findings: in terms of objective clearness male skaters at international master sportsman level are superior to male skaters at national master sportsman level, but in terms of renitency male skaters at national master sportsman level are superior to male skaters at international master sportsman level; female skaters at national master sportsman level are superior to level 1 female skaters in terms of renitency, determination, confidence and total score, and differences between them are significant; furthermore, by comparing volition quality between male and female skaters, the author found that in terms of toughness male skaters are superior to female skaters, and the difference is significant, but in terms of other 5 factors and total score, differences between them are not significant.

Results The average levels of PRL in patients with SLE was significantly higher than that in the controls(P＜0.01),and the levels of estradiot (E2)in cases in active stage was higher than that in the controls(P＜0.05).The level of testosteronein 31 cases decreased and compared with the controls,E2/T increased markedly(P＜0.01).The positive correlation was found between the levels of PRL and E2 in cases of active stage.

结果 SLE患者平均PRL水平较对照组明显升高(P＜0.01)，以活动期患者升高更为显著(P＜0.01)，同时活动期患者E2水平较对照组升高(P＜0.05)，31例患者T水平均明显下降，与对照组比较有非常显著性差异(P＜0.01)，E2/T显著升高，血清PRL水平与活动期患者E2水平呈正相关。

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。
