Objective To study the efficacy of intra-tumoral injection of different concentrations of ethanol for nude mice with implanted pancreatic cancer and provide evidence for choosing appropriate concentration of ethanol for clinical treatment of pancreatic cancer.Methods A subcutaneous xenograft mouse model of human pancreatic cancer SW1990 was established.Forty-eight nude mice with similar tumor size were randomly divided into 20％,40％,60％,80％,95％ ethanol injection groups and saline injection group.The longest (a) and the shortest diameters (b) of tumor of nude mice were measured.Tumor volume (TV),relative tumor volume (RTV) and the relative rate of tumor proliferation (T/C％) were calculated.Eight days later the nude mice were sacrificed.The tumor tissue was harvested for pathologic examinations.Results RTV in 20％ ethanol injection group was similar that of saline injection group (P =0.212).RTV in 40％,60％,80％ and 95％ ethanol injection groups were significantly lower than that in saline injection group (P ＜ 0.01).RTV was less than 1 and T/C％ was less than 30％ in 60％,80％ and 95％ ethanol injection groups.The values of RTV and T/C％ decreased with the increase of ethanol concentration.RTV in 80％ and 95％ ethanol injection groups were significantly lower than that of 60％ ethanol injection group (P =0.003 and P =0.009).RTV was similar in 80％ and 95％ ethanol injection groups (P =0.819).The pathologic examinations showed no tumor necrosis in saline injection group,while small amounts of necrosis in implanted pancreatic cancer was observed in 20％ and 40％ ethanol injection groups,while a large area of coagulation necrosis could be found in 60％,80％ and 95％ ethanol injection groups.Conclusions Intra-tumoral injection of 80％ ethanol is feasible therapy method for nude mice with human pancreatic cancer xenografts.

Objective To evaluate the efficacy and salty of endoscopic ultrasonography-guided celiac plexus neurolysis (EUS-CPN) in the treatment of pain due to pancreatic cancer and celiac metastatic carcinoma.Methods Thirty-three patients with celiac carcinoma were selected for EUS-CPN. Among whom 15 pateints were received chemotherapy before procedure . Using endoscopic ultrasounography,transgastric injection of the celiac plexus with bupivacaine and 98% dehydrated absolute alcohol was accomplished.The abdominal pain was evaluated by the numeric pain intensity scale before and at 24,48,72 hours and one week after the precedure.The successful rate of precedure,the complication and the relief of the pain were observed. Results All procedures were performed successfully . No serious complications such as pancreatitis by trauma,pancreatic fistula,bleeding and celiac infection was found.Compared with baseline,pain was significantly relieved at 12,24,72 hours and 1 week after EUS-CPN (100%,98%,90% and 88%,respectively).The pain remission at 24,48,72 hours and one week in patients who received chemotherapy before procedure were 100%,100%,980% and 98%,respectively,while in those who had not treated chemically were 100%,98%,95% and 90%,respectively.The complete%relief of pain in chemotherapy group was significantly higher than that in nonchemotherapy group (75 % vs 56 %,P%0.05).Conclusions EUS CPN is a safe and effective method for relieving pain with low complications.It can raise the quality life of the patients and chemical therapy may be helpful in pain control.

Objective To investigate the effects of epidermal growth factor (EGF) on the proliferation , migration and apoptosis of adipose-derived stem cells (ADSCs) in vitro. Methods Starved cell model and FasL-induced apoptosis model were established in serum-free media. The effects of 10 nmol/L and 100 nmol/L of EGF on the proliferation, migration and apoptosis of ADSCs in vitro were observed. The exrpessions of signal pathway proteins like phospholipaseC-γ(PLC-γ) , extracellular regulated kinase (ERK) and AKT were also detected. Results The proliferation, migration and anti-ap-optosis of ADSCs were promoted by 10 nmol/L or 100 nmol/L of EGF, and the expressions of PLC-'y, ERK and AKT were up-regulated. Conclusion EGF can promote the proliferation, migration and an-ti-apoptosis of adipose-derived ADSCs in vitro.
