The design and synthesis of photocatalytic materials and their application in environmental pollution control and resource recycling have been reported in many literatures. However, most photocatalytic materials contain transition metal ions, and the environmental risks of leaching 1imit the application of catalytic materials. Silicon carbide (SiC), as the representative of the third generation of semiconductor materials, has a good potential application prospect in environmental pollution prevention because of Is characteristics such as no transition metal ions, high temperature and acid-alkali resistance, strong stability and so on. In recent years, some literatures have reported the synthesis, modification and application of SiC as photocatalyst n environment and resource recycling -fields. However, few temperatures have reviewed the application progress of SiC photocatalyst. In view of the above situation, the progress in the -field of SiC photocatalysis application in recent years was reviewed in tins paper, including synthesis method, doping medication and application, and the prospects of the photocatalyst system were also prospected.

Psychological pharmacology is a brand-new discipline that studies the interaction between psychological state and drugs,explores general rules of the effects of mental state on drug activity,and promotes rational use of drugs in clinical practice. Evidence showed that depression could affect the levels of endogenous substances,drug metabolizing enzymes and drug transport protein, thus influencing drug metabolism and efficacy. In clinical practice, medication recognition might affect drug choice and medication compliance of patients. The application of placebo might achieve positive treatment outcomes in certain patients. These research results indicate that attention should be paid to the psychological state of patients in drug treatment. In accordance with changes of physiological and psychological changes of patients,therapeutic regimens should be duly adjusted. Rational drug use education and psychological support should be provided to patients,so that patients' psychological burden could be relieved and therapeutic efficacy improved. [ABSTRACT FROM AUTHOR]
