Some non treatment variables that affect the outcome of a disease are often called covariates. These covariables should be considered in the design and analysis of clinical trials to obtain unbias conclusion. To ensure that any observed treatment effect is not influenced by an imbalances in baseline characteristics, both preadjustment and postadjustment are provided in the design stage and analysis stage of the trials respectively. They can improve the credibility of the trial results and increase the statistical efficiency. Based on a few papers published about adjustment for covariates and some documentations of the International Conference on Harmonization (ICH), we review the concepts, methods and procedures for adjustment of treatment effects for the influence of covariates. The statistical issues on the application of adjustment are especially discussed in great depth.

Objective: To research effect of different doses of Changle on the structure and function of rat liver.Methods: 180 healthy Wistar rats were divided into 5 experimental groups according following doses: 0.1,0.2,2.0,10.0 and 20.0 mg*kg-1,respectively, and the control group given physiological saline for six months. The changes of liver structure were examined by means of normal histological chemistry and transmission electron microscope(TEM). Results: The body weight of animal was linearly increased with the decrease of administered doses, gradual reduction of glycogen in hepatocytes and infiltration of inflammatory cells in the portal area were found in the group of 20.0 mg*kg-1. Changes of ultrastructure showed there were dense bodies and lysosomes containing dense granules in Kupffer cell and hepatocyte,and they were increased along with doses adding. Nuclei deformed, ALP and GPT in serum were rose in the group of 20.0 mg*kg-1. Different doses of Changle could lead to distinct biological effects. Conclusion: Long-termed administration of 20.0 mg*kg-1 Changle can lead to damage of structure and function of rat liver.

Objective:To probe into the long-term effect of La(NO3)3 fed orally on gast ric mucosa of rats.Methods:The gastric mucosa of rats was studied after La(NO3)3 was administe red orally for a long-term,by the use of ordinary histological technology and m orphometry.Results:In the groups of 20 mg·kg-1 and 10 mg·kg-1,the cytopl asma of more parietal cells lying in the top of the gastric gland was loose.Proporti on of cell types of the gastric gland was related to the doses. The acid mucus l evel of the mucous neck cells of male rats in the groups of 20 mg·kg-1 an d 10 m·kg-1 decreased. In the groups of 2 mg2kg-1, 0.2 mg·kg -1 and 0.1 mg*kg-1,the acid mucus level of the mucous neck cells of both male and female rats increased.Conclusion:La(NO3)3 fed orally for a long-term could injure gastric muc osa in higher dose (20 mg·kg-1,10 mg·kg-1) but promote the protect ive action of the gastric mucosa in lower dose (0.2 mg·kg-1,0.1 mg·kg- 1).

Hexafluoroisopropanol (HFIP)-induced sodium dodecyl sulfate/dodecyltrimethylammonium bromide (SDS/DTAB) catanionic surfactant coacervate extraction method coupled with high performance liquid chromatography (HPLC) was used to detect the migration of phthalates from disposable tablewares to drinking water. The concentration factors are larger than 82 and extraction recoveries over 53%for water samples spiked with 100 or 200 ng/mL phthalates. Limit of detection is in the range of 1.0–2.6 ng/mL. Good linearity with correlation coefficients larger than 0.9985 is obtained in the concentration of 20–1500 or 40–3000 ng/mL. Relative recoveries are from 82.4%to 123.6%for water samples spiked with 30/60, 250/500, and 1500/3000 ng/mL phthalates, respectively. Relative standard deviations (RSDs) are 0.4%–7.4% for intraday precision (n ? 5) and 0.6%–7.8% for interday precision (n ? 3). Four of studied phthalates are found in the drinking water samples prepared from four kinds of tablewares.

Objectives: To investigate the affecting factors on expenditure in Medical insurant inpatients. Methods: 593 medical insurant inpatients, who were from Feb 1, 2001 to Feb 31, 2002 in Nanjing Jinling hospital, were enrolled in this study. The inpatient expenditure was analyzed from the aspect of operation or not, age, and payment mode, used the descriptive analysis and multi factor analysis on affecting factors of the total expense, self bearing expense, and self affording expense. Results: The hospitalized days, operation or not, severity of disease were important affecting factors. The self bearing expense of medical insurant inpatients was associated with hospitalized days, operation or not, and total expense. While the self affording expense of them was associated with expense of drug, hospital bunk, radiation and others. Conclusions: We can control these associated affected factors to lighten the economic weight of patients, and to reduce the ratio of individual payment.
