RESUMO

<p><b>OBJECTIVE</b>To investigate the clinical response, pathological complete response (pCR), tumor resection rate and safety of neoadjuvant chemotherapy with docetaxel and epirubicin (ET) for locally advanced breast cancer (LABC).</p><p><b>METHODS</b>From March to December 2001, 40 women with LABC, aged from 28-67 (medium 48) years were alloted. Twenty patients had clinical stage IIIa disease, 15 had stage IIIb disease and 5 stage IV patients who had ipsilateral sura-clavicular metastasis. The dose was: epirubicin (E) 60 mg/m2, docetaxel (T) 75 mg/m2 every 3 weeks, with G-CSF given preventively. After 2 cycles of ET, a pilot clinical response evaluation was performed by investigators for each patient to decide if she should receive another 1-2 cycles of ET before surgery or radiation therapy.</p><p><b>RESULTS</b>Thirty-eight patients received 2-3 cycles of ET regimen. The pCR, clinical complete response (cCR) and clinical partial response (cPR) rates were 15.0%, 20.0% and 52.5%, respectively. Tumor resection rate in this group was 92.5%. Incidence of III/IV Grade neutropenia was 8.4%/14.0% of cycles, and 3 patients suffered from neutropenia with fever. Non-hematological adverse events were alopecia, nausea, vomiting, fluid retention, myalgia, arthralgia and nail disorders, which were mild to moderate.</p><p><b>CONCLUSION</b>Neo-adjuvant chemotherapy with a combination of docetaxel and epirubicin is effective and well tolerated by women with locally advanced breast cancer.</p>

RESUMO

Objective:To explore the pathogenesis of multiple organ dysfunction syndrome(MODS)with respect to the bal- ance of Th1/Th2.Methods:Eighteen healthy male minipigs,weighing 22-30 kg,were randomly divided into two groups: MODS group and control group.Double-hit method including hemorrhagic shock and endotoxiemia was used to establish the porcine MODS model.The peripheral vein blood samples were collected at different time-points(before bloodletting,before en- dotoxin injection,1 h,24 h,48 h and 72 h after endotoxin injection)in the two groups.The spleen samples were collected after death of the animals.Plasma levels of IFN-?and IL-4 were detected by enzyme-linked immunosorbent assay(ELISA).Real- time PCR was used to detect the expression of IFN-?,IL-4,T-bet and GATA-3 mRNA(The latter 2 were the key transcription factors associated with Th1/Th2 response)in the spleen samples.Results:The plasma levels of IFN-?and IL-4 quickly reached the peak values 1 h after the endotoxin injection,then the level of IFN-?decreased quickly.The ratio of IFN-?/IL-4 was signifi- cantly lower than the baseline value 72 h after endotoxin injection(P=0.000).The ratio of IFN-?/IL-4 mRNA in MODS group was obviously lower than that in the control group(P=0.020);the ratio of T-bet/GATA-3 was also lower in MODS group (P=0.038).Conclusion:The shift from Th1 to Th2 occurs in the progress of MODS.
