Regorafenib,an oral multi-kinase inhibitor,can inhabit a class of receptor tyrosine kinase,such as angiogenic,stromal,oncogenic and so on.Studies in vitro and clinical trials indicate that Regorafenib has significant antitumor activity.The results of clinical trials are encouraging for the treatment of Refractory solid tumors,especially for colorectal carcinoma.

[ ABSTRACT] AIM: To explore the relationship between FRAS 1 protein and brain metastases of non-small cell lung cancer (NSCLC).METHODS:The mRNA expression of FRAS1 in the brain metastatic tumor tissues and primary tumor tissues of NSCLC was detected by qPCR .The protein expression of FRAS 1 in the tumor tissues and normal tissues adjacent to tumor tissues of NSCLC was measured by SP method of immunohistochemistry .The protein expression of FRAS 1 in NSCLC primary tumor tissues with or without brain metastases was also determined .RESULTS:The mRNA expression of FRAS1 in the brain metastatic zone was nearly 10 times higher than that in the primary tumor tissues , and there was sig-nificant difference between the 2 groups (P<0.05).FRAS1 protein was expressed in the NSCLC primary tumor tissues , but was not found in the normal tissues adjacent to primary tumor tissues .The protein expression of FRAS 1 in the NSCLC with brain metastases was significantly higher than that without brain metastases ( P<0.01 ) .CONCLUSION: FRAS1 protein may be associated with the occurrence of NSCLC .The over-expression of FRAS1 protein may be related to brain metastases with NSCLC .

Hospitals without disciplines have no performance performance,the focus of performance reform lies in mechanism transformation.Hospital performance management and discipline construction are interdependent relationships.Performance management provides guidance and motivation for the process of discipline construction,the construction of disciplines provides a value basis for the business connotation of performance management.Guiding discipline construction by clarifying the disease efficacy system.Clarify discipline construction by refining the technical system.Quantify discipline construction by organizing departmental projects.Transform financial and personnel performance assessment into technical value management.The conjugate mechanism can trigger and drive the deployment,support,and fulfillment of business.Performance management plans are only effective when they are publicly available.Only solutions that comply with business logic can be made public.By mining valuable data,we tap into potential business value.

There are many kinds of medical facial protective equipment with different functions. However, due to the lack of recognition of the hazards of facial occupational exposure, an incomplete understanding of the functions and effects of protective equipment and a lack of awareness, the proportion of staff that wear protective equipment in the Department of Stomatology is low. In this paper, the harmful and protective effects of face occupational exposure of dental staff were reviewed. A literature review showed that with the increasing prevalence of infection with AIDS, hepatitis B, hepatitis C and multidrug resistant bacteria in recent years, the occupational infection rate of medical staff in the Department of Stomatology has increased. The noise generated during oral treatment and the light from photosensitive curing lamps and treatment or surgical lasers can also cause occupational damage to hearing and vision. Face protection measures lack comprehensive functioning, and there is a lack of products that can be easily worn, indicating that the functions of face protection products need to be improved and strengthened. To minimize occupational infection and injury, we should not only improve the existing protective equipment but also improve personal protection awareness through advertising and education and comprehensively explore effective measures to improve occupational safety to ultimately achieve safe and high-quality medical services.
