Objective To determine whether intravesically administered Adriamycin can prevent superficial bladder tumor to recur through assessing the efficacy of with intravesical Adriamycin and without intravesical Adriamycin after TURB-t. Method The search strategy was made according to the demand of Cochrane Collaboration. Medline, Embase，CBMdisc and the Cochrane Library were searched for RCTs. Data were extracted by two reviewers using the designed extraction form. RevMan were used for data management and analysis. Results Thirty three relevant trials were searched, of which eighteen trials were included and fifteen trials were excluded. Meta-analysis showed intravesically administered Pirarnbicin (THP), Epirubicin (EPI) and Adriamycin (ADM) can reduce the recurrence rate of superficial bladder cancer after operation during one or two years. Conclusions Intravesically administered THP, EPI and ADM can reduce the recurrence rate of superficial bladder cancer after TUPB-t’s operation during one or two years. In addition, the factors affecting the prognosis should be performed, such as the dosage of irrigation of bladder, reserving time and the course.
Objective To assess the efficacy and the treatment-induced side effects of intravesically administered Epirubicin (EPI) following TUR in patients with Ta and T1 superficial bladder cancer compared to TUR alone. Methods According to the Cochrane reviewer’s handbook, included studies were those on patients with histologically confirmed Ta and T1 bladder cancer. EPI and EPI derivatives, dose and schedule would be considerd appropriate for inclusion. The search strategy was developed according to the Collaborative Review Group search strategy. Medline, EMbase, CBMdisc and the Cochrane library, articles of conference proceedings, and academic collections were searched for randomised controlled trials (RCTs) and quasi-RCT comparing intravesical EPI following TUR with TUR alone. Data were extracted from each identified paper independently by two reviewers. Trials were assessed for quality according to the method of Jadad scale. RevMan4.2 software developed by the Cochrane Collaboration was used for satistical analysis. Results Two hundred and thirteen related articles were identified, but only 10 were included in our systematic review. 3 articles were high quality and the rest were low. The pooled RR=1.51 (95%CI 1.32 to 1.72) and the pooled RR=1.49 (95%CI 1.35 to 1.66) in patients with Ta and T1 bladdercancer at 1 and 2 years respectively; The pooled RR=1.34 (95%CI 1.22 to 1.48) when comparing relative efficacy of intravesical EPI (drug doselt;50 mg) following TUR with TUR alone; The pooled RR=1.63 (95%CI 1.48 to 1.79) when comparing relative efficacy of intravesical EPI (drug dosegt;50 mg) following TUR with TUR alone. RR=1.49 (95%CI 1.33 to 1.66) and RR=1.56 (95%CI 1.36 to 1.84) when comparing relative efficacy of single intravesical EPI following TUR with TUR alone respectively. RR=0.79 (95%CI 0.53 to 1.17) when comparing the incidence of disease progression of intravesical doxorubicin following TUR with TUR alone. RR=4.34 (95%CI 2.62 to 7.19) when comparing side effect of intravesical EPI following TUR with TUR alone. Conclusions Intravesically administered EPI following TUR in patients with Ta and T1 superficial bladder cancer may reduce the incidence of tumour recurrence, but cannot reduce the incidence of disease progreesion. Intravesically administered EPI following TUR has some side effects but can be tolerated and has no influence on the life of patients.

Objective To determine the best matching concentration of carbon nanoparticles suspension injection adsorb epirubicin by measuring the combination ratio of carbon nanoparticles suspension injection combined with epirubicin under different matching conditions. And then, to prove the adsorbability of carbon nanoparticles suspension injection adsorb epirubicin in vitro. Methods Firstly, epirubicin-carbon suspension of different concentrations will be prepared. The second, high performance liquid chromatography mass spectrometry（LC-MS） was used to assay the concentration of free epirubicin, and calculate the content of epirubicin that was combinated with carbon nanoparticles suspension injection. The difference of the ratio of carbon nanoparticles suspension injection combined with epirubicin under different matching conditions will be compared in the end. Results The combination ratio of carbon nanoparticles suspension injection combined with epirubicin solution of 5, 10, and 15 mg/ml were 85.6%, 85.7%, and 31.8%, respectively. Conclusions The adsorbability of carbon nanoparticles suspension injection adsorb epirubicin is favourable in vitro. Best matching concentration of carbon nanoparticles suspension injection adsorb epirubicin may be epirubicin solution of 5-10 mg/ml.
Objective To evaluate the effect of neoadjuvant chemotherapy on the expression of CXCR4 in breast cancer and its clinical significance.Methods The clinical data of 59 patients with breast cancer of stage Ⅱ and stage Ⅲ underwent neoadjuvant chemotherapy with paclitaxel plus epirubicin for 3 cycles between April 2005 and March 2009 were retrospectively analyzed. The expression of CXCR4 in the breast cancer tissues before and after neo-adjuvant chemotherapy was examined by immunohistochemistry and its relationship with clinicopathologic factors was analyzed.Results The CXCR4 positive expression was observed in 56 patients with breast cancer (94.9%), but not in corresponding nontumor normal tissues. The expression level of CXCR4 was correlated to lymph nodes metastasis (P=0.019) and breast cancer stage (P=0.040), but it was not correlated to age of patients, tumor size, grade, hormone receptor (ER and PR)， and HER2 status. The expression level of CXCR4 was significantly decreased after neoadjuvant chemotherapy. Decline extent of CXCR4 expression after chemotherapy and CXCR4 expression level were not correlated to the effect of neoadjuvant chemotherapy, while the effect of chemotherapy in patients expressed CXCR4 in cluster distribution was better than that in scattering distribution (P=0.015). Conclusion The decline extent of CXCR4 expression level after paclitaxel combined with epirubicin neoadjuvant chemotherapy is not correlated to the efficacy, but its expressing distribution may be considered as an index to the effect of neoadjuvant chemotherapy.
