OBJECTIVE:To evaluate the effect of temozolomide(TMZ)in combination with dexamethasone(DXM)on the proliferation of human gliocytoma U251 cells in vitro.METHODS:Human U251 cells were assigned to 1 of the 3 groups: TMZ(10,25,50,100,200,400?mol?L~(-1),respectively)alone or in combination with 40?mol?L~(-1)DXM(TMZ+DXM group)or control group(none drug).After treatment for 72 hours,the cell morphology,cell inhibition ratio,cell cycle and the apoptotic rate were detected.RESULTS:When TMZ concentration was greater than 100?mol?L~(-1)the cell inhibition ratio was higher in TMZ-treated group than in TMZ+DXM-treated group(P

The event of “diagnosing mental disorder but actually not” violates patients′right of informed con-sent and refused to health , showing some problems of “diagnosing mental disorder but actually not” and mandatory admission process and psychiatric judicial authentication , and also have some ethical problems .Therefore, relevant departments should perfect the laws and regulation , establish a hospitalized psychiatric patients appeal , the appeal channels , at the same time , physicians should follow a correct understanding , respect patients rights , disinterest-ed, the ethical principles of self -supervision and also use constraints should be regulated .

With Jianyu (LI 15), Jianliao (TE 14) and Jianzhen (SI 9) for instance, the three acupoints used to treat shoulder bi syndrome by needle knife, and through traceability and researching constant structure, the acupoint position, insertion trace, manipulation and clinical significance of needle knife medicine were discussed. Accurate position is one of the characteristics of acupoints selection of needle knife medicine. As for the acupoints selection method, the mean of body surface localization is always used. The phanerous or palpable bone processes, muscles and tendons are taken as positioning marks; pressing areas where appear sour, numb, or distensible and other sensations is considered as the principle of press positioning. So acupoints position method is the combination of observation and palpation. Different insertion methods can effectively relieve the accretive bursae synovialis, tendon, joint capsule and the compressed nerve, so that shoulder bi syndrome is relieved.

Objective To fully realize laboratory information sharing, giving full play of automation and intellectualization of laboratory devices and improving the management level and work efficiency. Methods A new network architecture method was adopted. The laboratory devices were connected by joining TS into the master network. A computer installing interface management program was used as device server. All laboratory instruments were managed by the interface management program. Results The new LIS realized the total inosculation of LIS and HIS and the connection method of different communication modes on many serial communication devices. Conclusion The method strengthens the system's network integration. The maintenance costs and PC resources are saved.

Objective To explore the distrbution characteristics of glutathione S-transferase T1 and M1 (GSTT1 and GSTM1) gene polymorphism of Daur population in Inner Mongolia region, and provide the relevant data for studying the genotype of minority ethnic group of the Inner Mongolia.Methods Genomic DNA was extracted from peripheral blood and the fragments of GSTM1 and GSTT1 was amplified by internal control allele specific PCR in 220 volunteers who had been residents in Inner Mongolia region. At the same time, the genotype of GSTT1 and GSTM1 was resolved by the density of 2.5% agarose gel electrophoresis.Results In the studied population, the frequencies of GSTM1 (-) and GSTT1 (-) were 50.8% and 71.4% respectively. The frequency of the individuals with combination of GSTM1 (-) and GSTT1 (-) was 31.4%.Conclusion The distribution of GSTM1 and GSTT1 displays gene polymorphism in Chinese Daur population, approximate to Mongolian population in the north of China, but there is significant difference between Chinese Daur population and Han people.

Objective To present a solution of the hospital information management access control for more secure information sharing. Methods Several commonly used access control models were compared. Some problems of the RBAC model were analyzed in the hospital information circumstances. Results A solution of space-based data access control was presented on the base of the role-based access control (RBAC) module. Conclusion The space-based data access control method can reduce space consumption and maintain data consistency, which is more suitable for the use of the hospital management information system.
