Blood were obtained for blood RT and plasma endotoxin concentration check. 6 All data underwent ANOVA analysis. Results: After 3hrs of LPS injection, 1 in hypermetabolic sepsis group, the average HR went to 334/min, the average body temperature went to 41.0℃, while in control group they were 274.9/min and 38.2℃ respectively. p=0.000, presented significant statistical differences. The average BP and breath rate in HS group were 97.1mmHg and 94.3/min , while they were 95.9mmHg and 76.4/min in control group, respectively presenting no statistical differences. 2 In HS group plasma endotoxin concentration was 0.088EU/ml while it was 0.013 EU/ml in control group presenting statistical significance, p=0.002. 3 Blood white cell ratio and total white cell counting were 82.73% and 1.90×109 in HS group, while they were 64.39% and 7.58×109 in control group presenting very significant statistical differences(p=0.001). There was no statistical significances in RBC counting and hemocrit between two groups.

In the second place, this paper uses the financial data reported by China's private listed companies and statistical analysis skills to test the theories and hypotheses. The research collects all required data from 2000 to 2002, examines the profit ability, the gain ability, the repay ability, and the cost control ability for all sampling listed companies by using Paired-Samples T test in the quantitative analysis section. The results show that these listed companies'profit decreases, income increases, repay ability enhances after the companies go public. Finally the paper takes the non-operating expenses as the illustrating index for the cost control capability of the companies to demonstrate that there is an obvious increase of non-operating expenses after getting great amount of money in IPO, in this sense it can be stated that there is the intendancy of low capital utility rate in private companies.

研究选用了描述性统计分析方法对样本企业IPO前后时段的财务指标进行了对比考查，并运用配对样本t检验方法进行了显著性检验，研究结果表明民营企业在IPO前后的盈利水平总体上是显著下降的；同时研究也显示虽然获利水平出现了小幅上升，但这是由于企业通过IPO融资增加了投资规模导致的；企业的偿债能力在IPO之后有明显的好转；研究最后以营业外支出作为企业成本控制能力的解释指标，发现企业在IPO上市融得大量资金后对主营业务以外的支出有明显的增多，可以判断民营企业存在资本利用效率低下的现象。
