Background and purpose: Pancreatic cancer is often diagnosed at advanced stage, therefore, chemotherapy remains the cornstone of treatment for advanced pancreatic cancer. However, no standard regimen has been established as second-line therapy for advanced pancreatic cancer. The purpose of the study was to evaluate the efifcacy and safety of albumin-bound paclitaxel plus S-1 for the treatment of advanced pancreatic cancer patients in second-line setting after the failure of gemcitabine treatment. Methods:Clinical outcomes of 19 patients with advanced pancreatic cancer were analyzed. These patients received albumin-bound paclitaxel plus S-1 as second-line therapy after the failure of gemcitabine treatment. Albumin-bound paclitaxel was administered at a dose of 125 mg/m2 over 30 minutes on day 1 and 8 of a 21-day cycle. From d1-14, all patients received oral S-1 40 mg/m2, twice daily. Results:All patients were available for evaluation. Of the 19 patients, 1 case got complete response (CR), 4 cases had partial response (PR) and 9 cases had stable disease (SD). The objective response rate (ORR) was 26.3%, the disease control rate (DCR) was 73.7%and the median progression free survival (PFS) was 5.2 months. The main toxicities include hematological toxicity, myodynia, gastrointestinal reactions, sensory neuropathy, fatigue and alopecia. Conclusion:The combination of albumin-bound paclitaxel and S-1 is effective and tolerated in the treatment of advanced pancreatic cancer patients who resistant to gemcitabine.

Objective To investigate the suppression to 2-glycoprotein-1-specific B cell response by human recombinant 2-glycoprotein-1 domain Ⅰ dimer(rh?2-GP1-DⅠ2) in rh?2-GP1 immunized mice.Methods The effects of treatment using rh?2-GP1-DⅠ2 on titer and ratio of anti-?2-GP1 were analyzed by solid phase ELISA.The number of splenic ?2-GP1-specific antibody-forming cells(AFC) was counted by ELISPOT.Results The levels of anti-?2-GP1 from rh?2-GP1 immunized mice treated with rh?2-GP1-DⅠ2 were significantly decreased compared with those in negative controls(P

Objective:To observe the change of CD4+CD25+regulatory T cells and Th17 cells in mice with experimental anti-phospholipid antibody syndrome ( EAPS ) .Methods: EAPS model was established by immunizing BALB/c mice with recombinant humanβ2 glycoprotein 1 (rhβ2GP1).The levels of serum anti-β2 glycoprotein 1 (anti-β2GP1),anti-cardiolipin antibody (aCA),IL-17,IL-2,IL-6 and TGF-βwere tested by ELISA.The rate of abortion,activated partial thromboplastin time (APTT) and platelet count were also detected.Flow cytometry was applied to detect the percentages of the CD4+CD25+regulatory T cells and Th17 cells in peripheral blood mononuclear cells.Results:Compared with the control group,the levels of anti-β2 GP1,aCA,IL-17,IL-2 and IL-6 were significantly increased,the rate of abortion was increased,APTT time was prolonged and the levels of TGF-βand platelet count were de-creased in model mice (P<0.05).No significant difference was detected of percentage of Treg cells in PBMC at the eighth weeks in model group (P>0.05),but percentage of Treg cells was lower than that in control group after 12 weeks (P<0.05);the percentage of Th17 cells in model group was higher than that in control group (P<0.05).In addition,the ratio of Treg/Th17 cells was lower in model mice than that in control group.Conclusion: The imbalance of CD4+CD25 Treg/Th17 cells may participate in the pathogenesis of EAPS.

Aim To investigate the effects of irbesartan on Wnt/β-catenin signaling pathway in tubular epithelial-mesenchymal transition(EMT)in HKCs induced by high-glucose.Methods Human kidney proximal tubular epithelial cell line(HKCs)cultured in vitro was divided into four groups:normal-glucose group,mannitol control group,high-glucose group and high-glucose plus irbesartan group.Immunocytochemistry staining was used to observe the expression of β-catenin;the protein expression of Wnt4,β-catenin,E-cadherin and α-SMA was assessed by Western blot;Wnt4 and β-catenin mRNA were detected by reverse transcription-polymerase chain reaction(RT-PCR).Results Compared with normal-glucose and mannitol control group,both the protein and the mRNA of Wnt4 were up-regulated in HKCs stimulated by high-glucose.α-SMA expression significantly increased but E-cadherin decreased in HG group.The cytoplastic and nuclear fraction of β-catenin enhanced with highglucose stimulation.But no difference of the total protein and mRNA of β-catenin was observed between highglucose-treatment and control groups.Highglucose induced Wnt4 and β-catenin expression in a time-dependent manner,both peaking at 24 h.Irbesartan reduced the promotional effect of HG on Wnt4 and α-SMA expression,and nuclear translocation of β-catenin.HG-mediated inhibition of E-cadherin was also restored by irbesartan.Conclusion These data supported a functional role for Wnt/β-catenin signaling pathway during epithelial-mesenchymal transition of HKCs induced by high glucose and suggested that irbesartan might reverse tubular EMT by regulating activity of Wnt/β-catenin pathway.

OBJECTIVETo explore the effect of negative emotions on serum levels of adrenocorticotropic hormone (ACTH) and neuropeptide Y (NYP) in hepatitis B liver cirrhosis (HBLC) patients.

METHODSTotally 617 HBLC patients were assigned to the negative emotion group (415 cases) and the non-negative emotion group (202 cases) judged by negative emotions. Case numbers of various grading Child-Pugh were recorded in the two groups. Their liver functions were compared between the two groups. Serum levels of ACTH and NPY were detected using double antibody sandwich enzyme-linked immunosorbent assay (ELISA) in the two groups.

RESULTSThere was no statistical difference in Child-Pugh grading between the two groups (χ2 = 0.65, P = 0.72). Compared with the non-negative emotional group, serum ACTH levels decreased significantly in the negative emotion group with statistical difference (P < 0.05). There was no statistical difference in serum ACTH levels between the two groups (P > 0.05).

CONCLUSIONThe negative emotion of HBLC patients was not related to the serum ACTH level, but to relatively lower-concentration serum NPY levels.
