Double template molecularly imprinted polymer ( D_MIP) was prepared by emulsion polymerization method using the nonylphenol (NP), bisphenol A (BPA) as templates, α_methyl methacrylate(MAA) as functional monomer. Then using the D_MIP as solid phase extraction materials, a method based on double_molecularly imprinted solid phase extraction coupled with high performance liquid chromatographic fluorescence detection was developed for the determination of trace NP and BPA from environmental and food samples. The D_MIP was characterized by Fourier transform infrared spectroscopy ( FT_IR ) and adsorption experiments. The results showed that the saturated adsorption capacity of the D_MIP for NP and BPA was 73. 3 and 97. 5 mg/g, respectively, and the relative selectivity coefficient was 2. 2 and 1. 7, respectively. Moreover, the conditions affecting extraction efficiency, such as washing conditions and desorption conditions were optimized. Under the optimal conditions, there was a good linear correlation in the concentration range of 0. 01-2. 3 mg/L with correlation coefficients (R2) greater than 0. 998 for NP and BPA. The detection limits ( S/N=3) were 0. 001 and 0. 002 mg/L. The proposed method was applied to determine NP and BPA in river water, beer and crucian carp samples. The recoveries of NP and BPA were in the range of 86. 4%-99. 1%with the relative standard deviation less than 6 . 2%. This method has good selectivity and high sensitivity and shows good prospects for the application in the enrichment and separation of NP and BPA in real samples.

Objective To discuss the surgical treatment for huge hepatoblastoma in children,and the technique of hepatectomy without blockade of the blood supply to the remained liver lobes.Methods We reviewed 12 cases of huge hepatoblastorna who had been operated from July 2001 to January 2009 in our hospital.The mean age of the children was 3.2 years(range,11 months to 12 years).The diameter of the tumor was from 10 to 23 cm.3～7 cycles of chemotherapy was routinely administrated before operation.When the tumor reduced to a certain size that radical resection could be performed safely,regular hepatectomy was conducted.Hepatoblastoma resection without blocking the blood supply to the remained liver lobes was performed in every patient.Results The operations were successfully accomplished in all the 12 children.5 cases received right trihepatectomy (segment Ⅳ,Ⅴ～Ⅷ),4 cases received right hemihepatectomy(segment Ⅴ～Ⅷ),and the other 3 cases received Ⅳ,Ⅶ,Ⅷ segmentectomy,right Ⅴ,Ⅵ segmentectomy,and left hemihepatectomy respectively.The intraoperative hemodynamic parameters were stable,and there was no perioperative mortality.Postoperative chemotherapy wag routinely administrated.The follow-up period varied from 2 to 92 months.11 children survived and were disease free,among those 6 children have survived for more than 5 years.One child had brain and lung metastasis 5 months post operation,and died 7 months post operation. Conclusion Preoperative chemotherapy administrated to children with huge hepatoblastoma can reduce the tumor size and render tumor reseetable.Hepatoblastoma resection without blocking the blood supply to the remained liver lobes is a safe and feasible surgical technique.

Objective To evaluate the in vitro differentiation of human amniotic epithelial cells (hAECs ) into hepatocyte-like cells. Methods Combined approach of dexamethasone, HGF, IGF and other cytokines were used to induce the differentiation of hAECs into hepatocyte-like cells. The induction lasted 2 weeks. During the induction, the expression of albumin ALB, CYP1A1, CYP1A2, IGFR, c-met and key functional genes related to liver cells as well as transcription factors HNF3, HNF4 and C/EBPa were monitored by RT-PCR. Time dependent changes of the surface marker colony ALB, AFP and CK18 were analyzed by cell flow cytometry. Results After the 2 week induction, the expressions of liver hepatocyte-like cell functional genes such as albumin, CYP1A1, CYP1A2, c-met, and transcription factors such as HNF3, HNF4, C/EBPa and HNF1 were observed. Six days after the induction, hAECs mainly were stained AFP+, and the positive rate was (15.1±2.1)%. While 10 days after the induction, part of the hAECs showed AFP+/ALB+ (6.5±1.4)%; and on 14th day, hAECs only showed ALB+, and the rate was (13.9±2.3)%. ALB+ cell increase indicated a gradual functional maturation from the hAECs to hepatocyte-like cells. Similaritly, the number of CK18+ cells in the whole population was also increased: On 10th day, the rate was (16.1±1.2)%; on 14th day, that was (21.3±4.6)%, which proved the above hypothesis of the trandifferentiation. By extending the induction time, the expression of functional genes increased gradually, and a maturing process of hAECs was detected by cell surface markers. Conclusion The differentiation of hAECs induced in vitro has the characteristics of hepatocyte-like cells.
