Objective To discuss the X-ray appearances of osteogenesis imperfecta.Methods The clinical and radiological manifestations of osteogenesis imperfecta in 10 child-patients were studied retrospectively.Results ①The change of osseous density:generalized osteoporosis with abnormal fragility of bone;②According to the abnormal contour of limbs bone,the patterns of lesions(10 cases) were categorized to four subtypes including long and thin type(3 cases),stumpy type(3 cases),pocketed and swelled lesions(2 cases) and blended appearances(2 cases);③Among the 10 cases,the lesions complicated by arthropathy were seen in 5 cases;④complicated by abnormal spines in 5 cases,pelvis deformity in 3 cases,chest deformity in 4 cases.Conclusion Radiological manifestations have certain clinical value in the diagnosis and typing of osteogenesis imperfecta.

Objective To explore the effect of sodium butyrate(NaB) on phosphorylation/ acetylation of histone H3(ph/acH3) at G?-globin gene and A?-globin gene promoter regions in K562 cells.Methods K562 cells were devided into 2 groups:K562 cells were grown in the presence or absence of 0.5 mmol?L-1NaB for 48 h [K562(NaB) group] and untreated K562 cells group(K562 group).Semi-quantitative RT-PCR was employed to measure the levels of G?-globin mRNA and A?-globin mRNA.The real time PCR-based chromatin immunoprecipitation(ChIP) was used to detect the levels of ph/acH3 at G?-globin gene and A?-globin gene promoter regions.Results Compared with the K562 group,there was a 1.4-fold(t=-149.022,P=0.000) and 1.2-fold(t=-13.363,P=0.000) increase in G?-globin mRNA and A?-globin mRNA,respectively,in K562(NaB) group.The level of ph/acH3 at G?-globin gene and A?-globin gene promoter region increased by 2.9-fold(t=-12.833,P=0.006) and 3.2-fold(t=-10.484,P=0.000),respectively,in K562(NaB) group,compared with the K562 group.The %Input value of G?-globin and A?-globin promoter fragment was 10.0-fold(P=0.000) and 9.5-fold(P=0.000) higher than that value of Necdin gene promoter fragment in the K562(NaB) group,while the %Input value of G?-globin and A?-globin promoter fragment was 3.2-fold(P=0.000) and 2.7-fold(P=0.000) higher than that value of necdin gene promoter fragment in K562 group.Conclusions NaB improves the phosphorylation and acetylation of H3 at ?-globin gene promoter regions,and this may be one of the mechanisms of expression of ?-globin genes induced by NaB.

Objective:To know the situation of continuing education for the hospital pharmacists in partial medical institutions of Guizhou province. Methods:An acquired questionnaire was designed and the investigation on partial hospital pharmacists in 91 medi-cal institutions was obtained, the times of participating in different medical conferences and continuing education programs in a year were recorded, and the interested continuing education programs were analyzed. Results:Totally 121 copies of questionnaires showed that 85. 95% hospital pharmacists had less than 5 times of participating in different kinds of medical conferences in a year, and less than 5 continuing education programs were held in 76. 03% medical institutions. The continuing education programs pharmacists inter-ested in were clinical pharmacy, clinical pharmacist training, pharmaceutical affairs management, basic knowledge, technology and practice training, and at the same time, 60 copies of questionnaire showed that there was a clinical pharmacist training plan in their hospital. Conclusion:The level of continuing education for the hospital pharmacists in Guizhou province is still low, and further edu-cation chances for the pharmacists are lacking. Therefore, it is necessary to increase the continuing education chances for the hospital pharmacists in Guizhou province and enhance the education level in order to improve the level of pharmaceutical care.
