Based on the investigation of Zaozhuang City in Shandong Province,the present situation of rice production in Zaozhuang was analyzed from the aspects of natural ecological conditions,varieties planted,cultivation techniques,pests and diseases.Existing problems were pointed out in aspects of cultivars,cost effectiveness of planting,irrigation and drainage facilities,production techniques,industrialization level,local governmen-tal management,and scientific research investment.Targeted countermeasures to promote the development of rice industry of Zaozhuang City were also proposed.

The objective of this study is to examine the protection effect of CPCC treatment in hepatic injury and the role of Calreticulin (CRT) in hepatic injury. The control and alloxan groups were given water and the CPCC group was given CPCC (Cr3+40μg/kg.d) every day, respectively. After 4 weeks, the alloxan and CPCC groups were injected with alloxan (40mg/kg) for 6d. Total protein was extracted from mice liver. SDS-PAGE and two-dimensional electrophoresis (2-DE) were performed in this study from the total protein of mice hepatic. The samples of 2-DE were analyzed through Time of Flight Mass Spectrometer . The mRNA of CRT was detected using fluorescence quantitative polymerase chain reaction (qPCR) in mice liver. The results of 2-DE and qPCR showed the expression of CRT had significant difference among controlalloxan and CPCC mice both on the transcriptional and protein levels. CRT is a potential target as the roles of treatment and prevention in hepatic injury. CPCC is expected to become new health product for prevention and treatment of the hepatic injury.

【Objective】 In order to clarify the mechanism of silicon(Si) in enhancing the resistance to water stress,the effects of Si on the physiological and biochemical characteristics of the roots of rice seedlings were investigated under water stress.【Method】 The effects of exogenous Si on the physiological and biochemical parameters of roots of rice [(Oryza sativa ssp.(keng) Ting cv.Xiushui 11) and Brazilian upland rice(O.sativa cv.IAPAR 9)] were investigated under water stress induced by polyethylene glycol(PEG) in hydroponic conditions.【Result】 Exogenous Si could restrain excessive respiration,and increase the dry matter weight and relative water content of the PEG-stressed rice roots.On the 8th day after PEG treatment,the malondialdehyde(MDA) content in the roots of both Si-treated rice cultivars was decreased by 23% and 21%,and the relative electrolyte leakage was decreased by 39% and 38%,respectively,as compared to those of PEG treatment only.Consequently,the plasma membrane stability of the stressed roots was enhanced by Si application.In addition,exogenous Si also increased the root antioxidant defense capacity,slowed down the degradation of abscisic acid(ABA) in rice roots under PEG stress.【Conclusion】 Silicon application could enhance the resistance of rice roots to water deficit stress by preventing the rapid decline of physiological and biochemical activities in roots.
