Background and purpose: Pancreatic intraepithelial neoplasia (PanIN) may be a precursor lesion of inifltrating pancreatic ductal adenocarcinoma. The mutation of the phenotypic impact of K-ras G12D alone, silencing of p53 and p16 could promote this process. The role of Smad4 in this progression was poorly understood. In our previous studies, we investigated that RNA interference silence of Smad4 to promote the PanIN cell malignant transformation. In the present study, we investigate. The further explores the siRNA interference of Smad4 expression on PanIN cells could lead to proliferation and metastasis in vitro and in vivo. Methods:Smad4 knock-down PanIN cells (PanIN-S) were established by stable transfection with lentiviral-mediated Smad4 RNA interference. In vitro,silence of Smad4 enhanced the proliferation of PanIN cells as determined by cell counting. A soft agar assay was used to assess the anchorage-independent growth ability of cells. Cell migration and invasion assays were performed using transwell chambers with or without Matrigel. In xenograft model experiments, PCNA, VEGF and MMP-9 staining was separately used to evaluate cell proliferation and angiogenesis and migration (VEGF and MMP-9). Results:Effect of siRNA of Smad4 gene in PanIN cells was conifrmed by real-time RT-PCR and western blot. In vitro, silence of Smad4 enhanced the proliferation of PanIN cells as determined by cell counting. Soft agar assay showed that there were more colony cell numbers in PanIN-S cells compared with PanIN cells (P<0.05). Using the transwell assay, we observed that PanIN-S cells migrated faster than PanIN cells and similar results were obtained by Matrigel assay (P<0.05). Furthermore, immunohistochemical analysis of the harvested tumors suggested that Smad4 silencing was associated with cell proliferation (PCNA reactivity) and angiogenesis and migration (VEGF and MMP-9), and the expressions of PCNA, VEGF and MMP-9 in PanIN-S group were signiifcantly increased (P<0.05). Conclusion:Silence of Smad4 in PanIN cells enhanced progression to invasive adenocarcinoma of the pancreas by promoting cell growth, migration and invasion. Smad4 might be a new diagnostic marker in pancreatic cancer and prove to be a feasible and novel target for therapeutic intervention.

Objective To investigate the adjuvant effect of dimo-thylidioctyl ammonium bromide (DDA) and/or DDA-BCG polysaccharide nucleic acid( BCG-PSN), which was combined with a Mycobacterium tuberculosis fusion protein AMM ( Ag 8 5 B - MPT64190-198 - Mtb8.4 ) to boost BCG primed immunization. Methods DDA with or without BCG PSN was mixed with the fusion protein AMM to construct the boosting vaccine. Mice were immunized with BCG and then boosted twice with AMM formulated with the adjuvant DDA with or without BCG-PSN. PBS or BCG vaccination without boosting was used as control. The humoral and cell-mediated immune responses were analyzed by ELISA and ELISPOT. Moreover, the protective efficacy of BCG prime-AMM subunit vaccine boosting against Mycobacterium tuberculosis infection was analyzed. Results With in vitro stimulation of Ag85B and PPD( purified protein derivative) antigen, the number of IFN-γ secreting cells from the mice boosted twice by AMM/DDA/BCG-PSN and AMM/DDA were higher than BCG and PBS group (P <0.05). The CFU in lungs of mice boosted with AMM/DDA/BCG-PSN was less than that of PBS group(P <0.05), while the CFU of AMM/DDA-boosted mice was less than that of BCG and PBS group(P < 0.05).However, fewer lesions were seen in lungs of mice immunized with BCG alone or BCG-prime-AMM/DDA/BCG-PSN boosting than the other groups. Conclusion DDA is an idea adjuvant for tuberculosis subunit vaccine;BCG-PSN might play a role in alleviating the immunity-mediated pathology.

BACKGROUND:Surgical treatment for pigmented vil onodular synovitis can maximize the excision of synovial lesions and recovery of joint function.
OBJECTIVE:To investigate the knee joint function and relapse rate fol owing treatment of pigmented vil onodular synovitis with total knee replacement and arthroscopic synovectomy.
METHODS:We retrospectively analyzed 34 cases of knee pigmented vil onodular synovitis admitted for surgical treatment in the Department of Orthopedics, Xiangya Hospital of Central South University, China from December 2006 to December 2011. In these cases, 24 patients received arthroscopic synovectomy and 10 patients were subjected to total knee replacement. Adjuvant radiotherapy was conducted according to postoperative patient’s conditions. Lysholm scoring was employed in the arthroscopic synovectomy group, and American Knee Society scoring was used in the total knee replacement group. Knee function in two groups was compared before and after treatment. Fol ow-up observation was performed to compare knee function recovery and relapse rate between two groups.
RESULTS AND CONCLUSION:Thirty-four patients were effectively fol owed up for 12-66 months, mean 41.3 months. Statistical analysis showed that in the arthroscopic synovectomy group, the postoperative Lysholm score was (86.3± 10.3) points, significantly higher than the preoperative score which was (55.5±13.2) points (t=3.81, P=0.016, P<0.05). In the total knee arthroplasty group, the American Knee Society score was increased from (40.7±2.2) points preoperatively to (90.2±1.1) points postoperatively (t=6.27, P<0.01). In the arthroscopic synovectomy group, the American Knee Society score was increased from (34.2±3.9) points preoperatively to (80.8±1.9) points postoperatively (t=16.58, P<0.01). Arthroscopic synovectomy combined with adjuvant radiotherapy can achieve better outcomes in pigmented vil onodular synovitis patients, while the total knee replacement for advanced with advanced knee diffuse pigmented vil onodular synovitis is better to restore knee function and the recurrence rate is low.
