[Objective] This paper aimed to investigate the effects of cadmium（Cd）stress on physiological and biochemical indexes in different maize cultivars and provide theoretical basis for the study on heavy metal ecotoxicology.[Method] The maize cultivars includeing Tienan 2,Yingdan 11 and Zhengdan 958 which were widely planted in Liaoning Province were selected as the experimental materials.And then the effects of different Cd2＋ concentrations on seed germination,physiological and biochemical indexes of young seedlings were investigated.[Result] The lower Cd2＋ concentration showed some the stimulation effect on seed germination of maize,while the higher concentration had obvious inhibitory effect to some extend.The seed germination of all the maize verities was obviously inhibited when the Cd2＋ concentration was more than 5 mg/L.And with the increasing of the Cd2＋ concentration,the seedling growth,exosmic conductivity and chlorophyll content of the maize varieties with different tolerance to Cd2＋ were distinctly changed.[Conclusion] The resistance of Tienan 2 to Cd2＋ was significantly higher than that of the other two varieties.

Relationship Between Hyperspectral Parameters and Physiological and Biochemical Indexes of Flue-Cured Tobacco Leaves

The experiment was set up for examining the physiological and biological indexes quickly and exactly, for obtaining information of tobacco-field fertilizing and tobacco growing. The ASD Field spec FR 2500 was used to measure spectra reflectance of flue-cured tobacco and the relationship between hyperspectral parameters and biochemical contents （total nitrogen, chlorophyll, carotenoid）, and physiological indexes （fresh weight, dry weight, moisture content） of flue-cured tobacco leaves was studied by correlation and stepwise regression statistic methods at different nitrogen and potassium levels. The results indicated that the spectra curves of different treatments had obvious rules and great diversities. There were high correlations between different types of spectra parameters and ten physiological and biochemical indexes of flue-cured tobacco leaves. Hyperspectral characteristic variables of ten physiological and biochemical indexes were found through stepwise regression, and SDr/SDb was the characteristic variable closest to seven biochemical contents. Simultaneously, the R2 and regression coefficient of equations reached 0.05 significant level and the equations had good estimating effects through the examination of other samples. Accordingly, this study suggested that the ten physiological and biochemical indexes could be estimated quickly by the estimating models, at the same time nitrogen-potassium fertilization and growth condition of flue-cured tobacco could be inspected.

Influence of Exercise at High Temperature on Blood Biochemical Indexes and HSP72 Expression in Adult Males

The influence of exercise at high temperature on adult males＇ routine blood indexes and biochemical indexes and the expression of HSP72 in peripheral blood lymphocytes （PBLs） was studied in order to provide theoretical ground for health supervision of adults receiving exercise at high temperature. 180 adult males were selected and divided into exercise group and control group, in which the exercise group was subdivided into subgroup 1 and subgroup 2 receiving exercise at high temperature in the afternoon and in the morning, respectively. Peripheral venous blood was phle- botomized before and after the exercise to examine routine blood indexes and blood biochemical indexes. The expression levels of HSP72 in PBLs were detected by flow cytometry. The results showed that the routine blood indexes and biochemical indexes in each group were within the range of normal values of male adults. There was no significant difference between each exercise group and control group in indexes before exercise. After exercise, the expression levels of HSP72 in PBLs in exercise groups were higher than those before exercise, and HSP72 expression levels in subgroup 1 were obviously higher than those in subgroup 2 and control group. The contents of ALT, urea, Na＋, Cl-, Ca2＋ and K＋ in subgroups 1 and 2 were lower than those in control group, but CK level was higher than in control group （P〈0.05）. The contents of Na＋ and Clin subgroup 1 were relatively lower than those in subgroup 2 （P〈0.05）. It was concluded that while receiving exercise at high temperature, adult males＇ HSP72 levels in PBLs could be increased and the biochemical indexes changed. Attention should be paid to health supervision to avoid obvious body injuries at high temperature.

Discrimination of TCM constitutions by biochemical and routine urine indexes

Objective:To investigate whether the specific traditional Chinese medicine(TCM)constitution of individuals can be defined by certain biological indexes instead of answering the questionnaire,and to explore the possibility of discriminating nine TCM constitutions from each other simultaneously using biological indexes.Methods:Blood and urine samples from 152 individuals with nine TCM constitutions were collected,and the related biological indexes were analyzed combining ANOVA,multiple comparison,discriminant analysis,and support vector machine.Results:We found that 4 out of 24 blood routine indexes,7 out of 10 urine routine indexes,and 12 out of 32 biochemical indexes showed differences among the constitutions.High-sensitivity C-reactive protein,apolipoprotein A1,and alkaline phosphatase were potential candidates for screening out individuals with unbalanced constitutions.Combining uric acid,high-density lipoprotein,apolipoprotein A1,creatine kinase,total protein,aspartate aminotransferase,total bile acid,dehydrogenase,sodium,and calcium levels had the potential to directly distinguish the nine TCM constitutions from each other.Among these indexes,the highest ratio of discriminant analysis between two constitutions was 95.5%,while the lowest was 66.1%.Conclusion:Our results suggest that some biochemical and urine indexes are related to various TCM constitutions,and thus they have the potential to be used for TCM constitution classification.
