Objective To improve the DXC series of psychology test instrument and its supporting software.Methods The nRF905 chip and STC89LE516AD chip were used to design the question system.Results Such shortcomings in the DXC-5 system were improved as overweight,too many link-wires,too much time in the initial deployment,etc.Conclusion The system can be used to select not only flight personnel and cosmonauts,but also personnel in other special professions.

OBJECTIVE:To provide reference for continuous improvement of drug counseling and pharmaceutical care. METH-ODS:220 cases of drug counseling answered by inpatient general pharmacist were collected from our hospital during 2012-2013, and the contents of drug counseling were classified and analyzed. RESULTS:Among consultants,73.18% of them were physi-cians;the type of drug involved mainly were antibiotics,accounting for 42.73%;main contents of drug counseling included drug selection,usage and dosage,accounting for 47.27%. CONCLUSIONS:Pharmacists provide drug counseling for physicians and nurses,answer various questions about usage,and guide rational drug use so as to enhance the communication between pharma-cists and physicians,nurses,and promote rational drug use in the clinic.

Objective:To observe changes of cerebral nerve cell apoptosis of the rat after acute stroke and the preventive and treating effect of Jiannao Decoction on the apoptosis.Methods:SHRsp rats were used to establish the model of acute stroke,which were treated with Jiannao Decoction.Symptoms and signs of the nervous system and changes of pathological structures of the hipocampus were investigated before and after establishment of the model,and changes of cerebral nerve cell apoptosis before and after establishment of the model and medication were investigated with TUNEL,immunohistochamical and Western blot methods. Results:The incidence rate of stroke in the prevention group was significantly lower than that of the model group(P0.05).Conclusion:Jiannao Decoction has significant protective action on brain in the rat with stroke,which is related with inhibiting the effect of nerve cell apoptosis and conduction of apoptosis-related signals.

Nano science, info science and life science are three major scientific fields in the 21st century. Because of the special physical and chemical character, the nanomaterials has been applied in many fields, and brings enormous progress to people's life. A new problem has turned to be the focus of people's attention, that is, whether nanomaterials may bring about harms to the organism and environment. This paper elaborates the background of biological safety of nanomaterials, the characteristic of the nanomaterials in environment, it emphases on the routes of exposure to the nanomaterials and its adverse affects to the organism and environment, finally shortage of the researches on this field was analyzed.
