ABSTRACT
Parkinson′s disease(PD)is a common disease caused by multiple factors and characterized by pathological degen?eration in the dopaminergic neural system. Based on its pathogenic factors,PD can be divided into several subtypes,so it is essential to develop therapeutic agents based on the main pathogenic factor of each subtype of PD. Recently it is confirmed that the mutation of leucine-rich repeat kinase 2(LRRK2)gene leads to increased activity of the LRRK2 notably,and then causes neurodegeneration. Thus developing LRRK2 inhibitors to modulate the kinase activity will be a novel therapy for the PD subtype which is caused by LRRK2 gene mutation. LRRK2,either a kinase or a GTPase,has two drug binding sites. Therefore,two types of LRRK2 inhibitors are being studied,one is the kinase inhibitor and the other is GTPase inhibitor. This paper summarizes the recent progress in the dis?covery and development of LRRK2 inhibitors.
ABSTRACT
Objective:According to the tumor of children psychology, explore a set of suitable for children accurate tumor radiotherapy positioning method, in order to improve the positioning accuracy, thus improve the tumor clinical cure rate.Methods: 1.Eliminate fear; 2.Adaptability training; 3.The methods of psychological suggestion. Evaluation method: take psychological induction of radiation induced by radiation therapy in children with and without taking mental children from the placement time, downtime in drug utilization rate, treatment rate and bit error rate comparison.Results: There is obvious difference between two groups (P<0.05).Conclusion: radiotherapy positioning of children with psychological intervention in the method, can improve the treatment of children's compliance.
