Methodology: This research study was conducted at two oncology units of tertiary Hospital Rawalpindi. A prepost test intervention study design was used on 35 nurses by using Verity’s tools. Results: The mean scores of knowledge were calculated by Cochran’s Q test showed that knowledge scores have significantly increased with ‘educational training’ (p value < 0.001). The difference in the attitude of the nurses was not found to be statistically significant in repeated measure of ANOVA. Conclusion: The results show that knowledge is the weakest component and attitude is strongest component of oncology nurses ‘competencies in chemotherapy administration.展开更多

Methods： MTT assay and 3H-TdR incorporation assay were performed to evaluate the inhibitory effects upon the proliferation of glioma cells, and to compare the sen- sitivity of glioma cells to administration of CBP, Vm-26, MTX, and NIM with that of the administration of CBP＋NIM, Vm-26＋NIM, MTX＋NIM, CBP＋Vm-26＋MTX, or CBP＋Vm-26＋MTX＋NIM, respectively. Results： The inhibition rate of CBP＋Vm-26＋MTX＋NIM combination administration against glioma cells was 96.64%, higher than that of CBP＋NIM （69.03%）, Vm-26＋NIM （71.53%）, MTX＋NIM （52.75%）, CBP＋Vm-26＋MTX （78.59%） （P〈0.01）, and the dosage of CBP, Vm-26, and MTX was declined to 1/10- 1/100 that of respective use of CBP, Vm-26, and MTX. Conclusion： The curative effect of combination administration of CBP, Vm-26, MTX, and NIM was much better than that of respective administration, suggesting a higher inhibition rate and a lower dosage use.展开更多

Sensitivity and subgroup analysis were se- lected to minish heterogeneity. GRADEpro 3.6 profile recommended by Cochrane Collabration was employed for quality assessment of analyses. Finally, 13 eligible RCTs with 4216 patients were in- eluded in this review and 16 comparisons from 13 trials were involved for analysis. The pooled analysis revealed no significant difference between long-term and short-term duration [HR=0.99, 95% CI （0.89, 1.11）, P=-0.89]. Within the subgroup analysis, patients benefited from long-term instillations with a start regimen of one immediate instillation [HR=0.83, 95% CI （0.69, 1.00）, P=-0.05]. But patients were not suitable to receive long-term instillations with epirubicin （EPI） [HR=1.01, 95% CI （0.91, 1.13）, P=0.78] The progression rate was not reduced after long-term instillations [HR=0.96, 95% CI （0.66, 1.39）, P=0.82]. From our results, patients should not receive introvesical chemotherapy more than half a year. In contrast, patients with one immediate instillation are preferred to have a long-term duration at least one year. Long-term instillations can not reduce the progression rate.展开更多
