OBJECTIVE:To evaluate the pharmacoeconomics of cefathiamidine, ceftriaxone sodium, cefuroxime sodium, amoxicillin sodium/clavulanate potassium and cefoperazone sodium/sulbactam sodium in the treatment of pediatric bronchopneumo-nia,and to provide reference for rational drug use in the clinic. METHODS:By retrospective study,338 children with broncho-pneumonia were divided into groups A,B,C,D and E according to different therapy regimens. There were 75,65,76,66 and 56 cases in groups A,B,C,D and E,and they were given cefathiamidine,ceftriaxone sodium,cefuroxime sodium,amoxicillin sodium/clavulanate potassium and cefoperazone sodium/sulbactam sodium intravenously. The pharmacoeconomics of therapy regi-mens in group A,B,C,D and E were evaluated by cost-effectiveness analysis and decision tree analysis model. RESULTS:The effective rates of groups A,B,C,D and E were 93.33%,90.77%,96.05%,87.88% and 87.50%,respectively. The treatment cost of those groups were 1 929.09,2 173.73,1 611.91,1 661.42,1 801.32 yuan,respectively. The cost/effectiveness(C/E)ratio of those groups were 20.67,23.95,16.78,18.91,20.59,respectively. The treatment cost of group C was the smallest,so was the C/E. Results of cost-effectiveness analysis were supported by sensitivity analysis. CONCLUSIONS:Cefuroxime sodium is the best treatment for pediatric bronchopneumonia among 5 antibiotics in respect of cost-effectiveness.

Objective To study the relationship between the expression of breast cancer susceptibility gene (BRCA)1 and the pathological parameters in sporadic breast cancer. Method Immunohistochemistry was used to detect the expression of BRCA1 in 42 cases of breast cancer tissues and 30 cases of breast fibroadenoma tissues and analyzed the correlation of the results with other parameters which included tumor size,tumor type,histological grade and axillary lymph nodes metastases. Results The positive expression rate of BRCA1 was 52.4% (22/42) in breast cancer patients and 85.7% (36/42) in breast fibroadenoma patients. The lower positive expression rate of BRCA1 was found in axillary lymph nodes metastases (P < 0.05). The positive expression rate in stage Ⅲ of breast cancer was lower than that in stage Ⅰ (P < 0.05 ) and was also lower than that in stage Ⅱ (P < 0.05 ), but there was no significant difference between stage Ⅰ and stage Ⅱ (P > 0.05). No significant correlation was observed among expression of BRCA1 and tumor size, tumor type (P > 0.05). Conclusions BRCA1 plays an important role in pathogenesis and development of breast cancer.BRCA1 maybe a adjuvant index for treating breast cancer and estimating prognosis.

According to the base complementation, the principle antisense technology is the sequence specific binding of complementary antisense nucleic acids or their chemical modification to the nucleic acids in cells, resulting in the suppression or prevention of gene translation. For the treatment of cancer, a lot of antisense drugs have been designed, which target the genes involved in the pathogenesis of cancer. And some of them have been in clinical trials. The author reviewed the progress of the clinical trials of these antisense drugs.

Objective To explore the role of the change of the CD11b expression in hyperleukocytosis and acute promyelocytic leukemia(APL) differentiation syndrome, we observed the effects of all-trans retinoie acid(ATRA) and trioxide arsenic(ATO) alone or the combination together with daunorubicin (DNR) on CD11b expression of human APL cell line NB4 cells. Methods By using the mono-antibody of CD11b FITC-conjugated, we monitored the level of CD11b expression of NB4 cells by flow cytometry. Results With the length of the 1 μmol/L ATRA exposure,the CD11b expression was increased. Exposed to ATRA for 24 h, 48 h, 72 h and 168 h;the CD11b expression of NB4 cell was (33.34±3.15)%, (55.59±5.13)%, (86.08±5.12)% and (90.69±2.69)%, respectively which were higher than control group and the difference was statistically significant (P<0.01). With the length of the 1 μmol/L ATO exposure, the CD11b expression showed no significant difference with control group(P>0.05), but was significantly lower than that in ATRA exposure(P<0.01). Exposed to 1 μmol/L ATRA combined with 1 μmol/L ATO for 72 h and 168 h, the CD11b expression were (18.81±1.40)% and (25.61±4.54)%, which were significantly higher than that in control group (P<0.05, P<0.01), but significantly lower than ATRA exposure (P<0.01). With the exposure to 1 μmol/L ATRA combined with 1 μmol/L ATO and 1 μmol/L DNR, the CD11b expression was also significantly lower than ATRA exposure (P<0.01) and showed no difference with control group (P>0.05). Conclusion By avoiding the increase of CD11b expression of promyelocytic leukemia cells, ATRA combined with ATO or two drugs together with DNR could play a role in eliminating incidence of hyperleukocytosis and retinoic acid syndrome.
