To study the cost-effectiveness of temozolomide combined with radiotherapy in the treatment of glioblasto-ma. Methods:According to the clinical trial data, cost-effectiveness and sensitivity of the results was analyzed based on the domestic cost and consumption level. Results:Temozolomide combined with radiotherapy could prolong one month of overall survival with the additional cost of RMB 58 959. 7 yuan in each case when compared with radiotherapy alone. Conclusion:Temozolomide combined with radiotherapy has no advantage on cost-effectiveness when compared with radiotherapy alone.

It can be used for the detection of HFO 1366mzz E in the air of workplace

Objective To examine the role of p38MAPK in high glucose-induced apoptosis of osteoblast MC3T3-E1 cell line, and to investigate its effect on the expressions of apoptosis-related molecules including caspase3, bax, and bcl-2. Methods The lentiviral vector containing short hairpin RNA targeting p38MAPK was constructed. The cultured osteoblast MC3T3-E1 cell were divided into 5 groups:normal control group(A group), high glucose group(B group), p38MAPK-shRNA transfection group(C group), signal transduction inhibitor group(D group), and transfection with negative control siRNA group(E group). RT-PCR was used to determine the p38MAPK mRNA expression levels in MC3T3-E1 cells. Flow cytometry(FCM)was employed to detect the cell apoptotic percentage. The protein levels of apoptosis-related molecules p38MAPK, p-p38MAPK, caspase-3, bax, and bcl-2 were assayed by Western blot. Ultrastructural alternation of MC3T3-E1 cell was observed under transmission electron microscopy(TEM). Results The lentiviral vector containing short hairp in RNA targeting p38MAPK was successfully constructed and transfected into MC3T3-E1 cells. RT-PCR result suggested that the siRNA targeting p38MAPK could effectively reduce the p38MAPK mRNA expression level induced by high glucose in MC3T3-E1 cell line. FCM showed siRNA significantly decreased high glucose-induced apoptosis percentage of MC3T3-E1 cells(P＜0.01). Meanwhile, we also found the siRNA significantly attenuated the proteins levels of p38MAPK, p-p38MAPK, caspase-3, and gene bax induced by high glucose in MC3T3-E1 cells, whereas the protein level of gene bcl-2 was enhanced remarkably when compared with high glucose group and negative control siRNA group(P＜0.01, P＜0.05).Conclusion The iRNA targeting p38MAPK suppressed high glucose-induced MC3T3-E1 cell apoptosis via inhibiting the activation of p38MAPK signaling pathway, thereby reducing the expressions levels of p-p38MAPK, caspase-3 and gene bax, and up-regulating the level of gene bcl-2.

Stranging the communication between the clinical laboratory and clinical department,is useful to promote and enhance the quality of tests and clinical examination.The communication work organization and implementation has been effectively guaranteed by managing communication theories and multiple pathways of communication means to strengthen clinical laboratory and clinical department communication.

Objective To study the clinical characteristics of children with demyelinating disease.Methods Age of onset,presymptoms,clinical manifestations and auxiliary examinations of 51 children diagnosed as demyelinating disease were analyzed retrospectively.Results The onset age was from 3 months to 14 years,and the number of school age children was 38.Before illness,32 cases were relevant to infection,3 cases to vaccine inoculation.Most of children had acute courses.In the initial stage,32 cases with peripheral nervous demyelinating disease presented to paralysis of limbs;18 cases with central nervous demyelinating disease presented to visual disorder,somatasthenia,fever,convulsion and headache.The EMGs of children with peripheral nervous demyelinating disease showed nervous lesion.Among 18 children with central nervous demyelinating disease,17 cases showed abnomal signal on MRI or CT.Conclusions Children with demyelinating disease displays diversified clinical manifestations.By investigating case history combined with auxiliary exaninations,it is not difficult to make a correct diagnosis and its prognosis is good commonly.
