In chapterⅡ, considering GLMMs data which the number of high units is different and the number of low units is small and unbalanced, we Conduct a series of simulations, the simulations show that regardless of the number of the level 2 units,the Bayesian estimate of random effects residual variance is more precise than PQL and the PQL estimation deviates from the true value seriously; In terms of the fixed effects estimates, When the number of level 2 units is 20, The mean and median of the Bayesian estimate is more precise than PQL,But With the number of level 2 units increase,the estimate of two methods is similar. Thus, in practical applications, we recommend the use of Bayesian method.

第二章针对不同高水平单位数,低水平数较小且不平衡的GLMMs数据,进行模拟研究,研究表明:无论水平2单位数的大小,贝叶斯方法随机效应残差方差估计值远比PQL法更接近真实值,PQL法严重偏离了真实值;而对固定效应参数估计值,当水平2单位数为20时,贝叶斯法各参数的均数和中位数均要较PQL法更接近真实值,而随着水平2单位数的增加,两种方法在估计固定效应参数时相差并不大,因而,在实际应用中,推荐采用贝叶斯法。

Firstly, normal mice was given orally by SM(qd×2d), and the dysbacteriosis were caused in them ,and then they were given orally by STM,these mice were formed experimental salmonellosis models ,finally these salmonellosis models were treated by bifidobacterium ,and count respectively the cfu/g of STM number in the mice excrement during different time of therapy,detect the index numbers of liver and spleen respectively, detect content of TNF-a in blood and in spleen respectively.

先用硫酸链霉素给正常小鼠灌胃2d,出现菌群失调症状,再用STM灌胃造成小鼠STM感染,使用两岐双岐杆菌液干预治疗STM感染小鼠,检测不同治疗时间各组小鼠粪便STM菌落数、肝脾指数、血及脾中TNF-a的含量。采用SPSS12.0统计软件包进行数据处理分析,统计学方法采用双因素重复测量资料的方差分析、单因素随机化设计的方差分析、卡方检验、多组均数比较的非参数秩和检验。结果:随着治疗天数的增加,STM菌落数逐渐减少,未干预组、生理盐水组及双歧杆菌组比较结果均为P<0.01;组间比较,双歧杆菌组STM数下降最快。

Results show that with the increase of the apparent gas velocity in the riser,there is little change in negative pressure gradient in the standpipe.

结果表明:随着提升管内表观气速的增加,立管内的负压差梯度变化不大;而随着系统循环量的增加,立管内的负压差梯度以及滑移速度均增大;随着加入热解室内松动气量的增加,立管内尤其是立管上部的压力也随之增大,热解室内无论是移动床流动还是流态化流动均对立管的稳定性影响不大;但当热解室内的压力超过某一值时,立管内的料封很快被破坏,导致系统无法运行。

The result showed that the influence of temperature and RH on average price and rate of first class of flue-cured tobacco was similar, which showed a trend of parabola curve with temperature or RH increasing. The maximum value of average price occur at 38.0℃ and 87.0%, the maximum value of the rate of first class occur at 37.6℃ and 86.5%. The result also showed that when the temperature or RH was in the range of 37.5℃ to 38.0℃ or 85.0% to 88.0%, psychrometric difference was 1.5~2.0℃, the average price and rate of first class would exceed 10 yuan per kg and 40% respectively.

选择210例原发性高血压患者进行24小时动态心电图监测,分析HRV各相指标:SDNN[所有窦性心率R-R间期的标准差],SDANN(全程记录中每5分钟NN间期平均值的标准差),PNN50(全程记录中相邻NN间期差值>50ms的个数)和RMSSD(相邻NN间期差值的均方根)。

In this paper , the statistic significance and clinical application of forest plots in a meta-analysis have been fully discussed. If the horizontal line represents the 95% confidence interval of the indexes including odds ratio, relative risk, weighted mean difference, and standard mean difference crosses the vertical line, the effect of test group is not signficant with that of control group; if the horizontal line lies to the right of the vertical line, it indicates that the test group is significantly effctive. If the horizontal line lies to the left of the vertical line, it indicates that the control group is more effective.
