Background:Pancreatic cancer is obscure in onset and progresses rapidly with very poor prognosis. Photodynamic therapy( PDT)has been developed as a novel anti-tumor treatment modality since 1980s. At present,there are only limited researches on pancreatic cancer treated with PDT in vivo. Aims:To investigate the efficacy of quantum dots-RGD ( QDs-RGD)based PDT combined with gemcitabine for treatment of pancreatic cancer xenograft in nude mice. Methods:QDs-RGD probe was synthesized and nude mice bearing pancreatic cancer xenograft was established. Nude mice were imaged at 1,5,10 and 24 hours after injection of QDs-RGD and QDs by in vivo imaging system. Forty model nude mice were randomly divided into five groups:control group( without any treatment),simple illumination group( laser 630 nm, 120 J/cm2,20 min),PDT group(QDs-RGD 0. 5 nmol+laser irradiation),gemcitabine group(gemcitabine 50 mg/kg)and combination group(QDs-RGD 0. 5 nmol+laser irradiation+gemcitabine 50 mg/kg). All the nude mice were sacrificed 18 days later. Tumor weight and volume were measured and tumor inhibition rate was calculated. Results:Fluorescence of tumor was shown 1 hour after injection and became clearest at the 5th hour,then showing a decrescendo trend. Density of QDs surrounding tumor was significantly less than that of QDs-RGD and faded away at the 10th hour. Tumor weight and volume in PDT group,gemcitabine group and combination group were all significantly lower than those in control group and simple illumination group(P<0. 01),and those in combination group were significantly lower than those in PDT group and gemcitabine group(P <0. 05). No significant differences in tumor weight and volume were found between control group and simple illumination group(P >0. 05),as well as between PDT group and gemcitabine group(P >0. 05). Tumor inhibition rate in combination group,gemcitabine group and PDT group was 70. 5%,43. 5% and 37. 1%, respectively. Conclusions:QDs-RGD based PDT combined with gemcitabine can inhibit the growth of pancreatic cancer xenograft in nude mice,which introduces a new idea to the treatment of pancreatic cancer.

Objective To investigate the efficiency of transjugular intrahepatic portosystemic shunt (TIPS) with Fluency stent in improving the hepatic and renal function and survival rate in patients with decompensated cirrhosis.Methods The decompensated cirrhosis patients who were treated in our hospital from May 2008 to September 2011 were retrospectively analyzed.One group of patients (n =48) undergoing TIPS was randomly selected as treatment group,while another group of patients (n =48) treated by medicine and therapeutic endoscope was randomly chosen as control group.Clinical data and fellow-up data were retrospectively reviewed.There was no significant deviation in baseline characteristics (age,gender composition,etiology,renal function,hepatic function et al) among all the patients before the operations; The laboratory results of hepatic and renal function in 2 groups before and after operation (1 week,20 days,3 months,6 months,1 year,2 years,3 years) were recorded and compared with independent samples t-test or Wilcoxon rank sum test.The survival rates of two groups in 3 years were analyzed using Kaplan-Meier survival curve and compared with Chi-square test.Results Three years after the operation,there were significant differences between the treatment group and the control group in AST(70.8 vs.108.7 U/L,Z =-2.958,P ＜ 0.05) and TBIL (51.2 vs.76.2 μmol/L,Z =-2.004,P ＜ 0.05).The Cr value of the 3rd year after the treatment were (9928.2 ± 2363.8) in the the control group and (7742.1 ± 2845.6) μmol/L in the treatment group(t =-2.074,P ＜ 0.05).BUN of the 1st,2nd and 3rd years after the treatment were (2.0 ± 1.1),(2.3 ± 1.5),(2.5 ± 1.3) mmol/L in the treatment group,while it was (2.6 ± 1.1),(3.8 ±1.2),(5.4 ± 1.1)mmol/L in the control group.There was significant difference between the 2 groups (t =-2.222,-3.940 and-6.110,P ＜ 0.05).Comparing the survival rate in the 2 groups with Kaplan-Meier survival curve,the 3 year survival rate in the treatment group was 46.2％,while in the control group it was only 30.0％ (x2 =6.341,P ＜ 0.05).Conclusions Compared with medicine therapy and therapeutic endoscopy,TIPS with Fluency stent may improve the hepatic function,renal function and survival rate in liver cirrhosis patients.It is a safe and effective therapy choice for patients with decompensated cirrhosis.

Objective To investigate the value of interphase fluorescence in situ hybridization(FISH)technique and the detection of fusion gene in the diagnosis of acute myeloid leukemia(AML)M2 and M3 Methods FISH was used to detect the AML1/ETO fusion gene and/or PML/RARα fusion gene in incipient cases including 9 AML-M2, 12 AML-M3 and 10 AML undetermined as AML-M2 or AML-M3 primarily diagnosed by routine morphology though bone marrow,cytochemical staining and immunophenotyping,which can help diagnose and guide clinical therapy.Results 4 of 9 AML-M2 cases were AML1/ETO positive.Among 12 AML-M3 cases,10 were PML/RARα positive.1 case was detected AML1/ETO fusion gene.In 10 untonfirmed M3 or M2,3 case8 showed AML1/ETO,5 showed PMIJRARot fusion gene and the rest showed neither of the genes.Conclusion As a new technique of the molecular genetics,FISH is accurate, rapid and efficient.It would be of significance not only at diagnosis of AML,but also for subsequent clinical decision-making.

Objective To observe the effects of Yougui Pills (YP) intervention on SREBP pathway related factors of sterol regulatory element binding protein-1c ( SREBP-1c) , cholesteryl ester transfer protein ( CETP) and fatty acid synthase ( FAS) protein and gene expression in kidney yang deficiency hyperlipidemia rat model. Methods Sixty SD rats were divided into normal control group, model group (in the dosage of 2.43 g/kg), and YP group. Rat model of kidney yang deficiency hyperlipidemia was induced with intramuscular injection of hydrocortisone. Normal control group and model group were given normal saline, and YP group was given YP suspension intragastrically. After treatment, the hepatic pathomorphology of rats in the three groups was examined, and the contents of serum lipids were examined. Hepatic SREBP-1c, CETP and FAS protein expression was detected by Western-blotting method, and their mRNA expression was detected by real-time polymerase chain reaction ( RT-PCR) . Results Compared with the normal control group, serum triglyceride ( TG ) , total cholesterol ( TC ) , low-density lipoprotein cholesterol ( LDL-C ) contents were significantly increased (P<0.01), high-density lipoprotein cholesterol (HDL-C) was significantly decreased (P<0.01), and hepatic pathomorphological changes of hyperlipoidemia were obvious in the model group. Compared with the model group, TG, TC, LDL-C contents were significantly decreased ( P<0.01) , and HDL-C was significantly increased (P<0.01) in YP group. Model group had higher SREBP-1c, CETP and FAS mRNA and protein expression than the normal control group ( P<0.05) , while YP group had lower SREBP-1c, CETP and FAS mRNA and protein expression than the model group ( P<0.05) . Conclusion YP can decrease the blood lipid levels probably by down-regulating the expression levels of SREBP-1c, CETP and FAS gene and protein related to the the SREBP pathway in rats of kidney yang deficiency hyperlipidemia induced by intramuscular injection of hydrocortisone.
