Objective To summarize the experience in the diagnosis and treatment for solidpseudopapillary tumors of the pancreas (SPTP). Method In this study, 27 cases of SPTP from September 2000 to June 2007 were retrospectively analyzed. Results The median age of these 27 cases was 26 years. There were 26 females and 1 male. Epigastric pain was complained in 16 cases, abdominal aponia mass in 11 cases. Tumour marker level was within normal range. Ultrasonic manifestation usually shows cystic and solid lesion without blood signal. Lesions were typical with high blood supply in enhanced CT scan, cystic and solid component confounding in it. MRI revealed low-middle signal in T1 and middle-high signal in T2. Pancreaticoduodenectomy was performed in 9 cases, pancreatic local excision and pancreaticojejunostomy were performed in 4 cases, pancreatic local excision was performed in 6 cases, Distal pancreatectomy and spleen resection were performed in 8 cases. Post-operative pathology shows local lesion in 12 cases, invading the pancreatic parenchyma in 14 cases and intravascular tumor thrombi and lymphnode metastasis in 1 case. All cases were followed up with an average period of 26.1 months. There was no recurrence nor metastasis. Conclusion Solid-pseudopapillary tumor of the pancreas has a low malignant potential, affecting primarily young women. It has no typical clinical appearance. Enhanced CT scanning has the relative characteristic imaging. Complete resection usually results in long-term survival.

Aim To study the mechanism of synergistic antitumor of EBB and doxorubicin in doxorubicin-resistant MCF-7/ADR breast carcinoma cells.Methods The antitumor activity of doxorubiein alone and its combination with EBB were measured by MTT assay in MCF-7/ADR and MCF-7cells. The rate of doxorubicin-induced apoptosis and the protein and mRNA levels of P-glycoprotein(P-gp) were determined in MCF-7/ADR treated with EBB by flow cytometry (FACS), respectively.Laser scanning confocal microscopy was used to detect the intracellular accumulation of drug in EBB-treated MCF-7 and MCF-7/ADR cells.Results EBB had antitumor effects for MCF-7 and MCF-7/ADR.It could potentiate the antitumor effect of dororubicin with CDI of 0.73 and 0.49 for MCF-7 and MCF-7/ADR,respectively.EBB and doxorubicin acted synergistically in elevating apoptosis of MCF-7/ADR and downregulating the expression of P-gp in a dose-dependent manner in MCF-7/ADR.EBB restored the intracellular accumulation of doxorubicin in MCF-7/ADR cells in a dose-dependent manner.After pretreatment with EBB for 24 h and 48 h,the intracellular accumulation of doxorubicin and Rh123 was obviousely restored in MCF-7/ADR cells compared with control in a time-dependent manner.Conclusion EBB is a potential agent which has strong inhibitory effect on both multidrug resistant cells and their parental cells.EBB can significantly potentiate the antitumor effects of dororubicin in MCF-7/ADR cells by blocking the function of P-glycoprotein and inhibiting the expression of P-glycoprotein.
