Abstract
OBJECTIVE To investigate the biological effects and its relative mechanism of decitabine combined with anlotinib on multiple myeloma cells. METHODS The human MM cell lines and primary cells were treated with different concentrations of decitabine, anlotinib, and decitabine+anlotinib, respectively. The cell viability was detected and combination effect was calculated by CCK-8 assay. The apoptosis rate was measured by flow cytometry and the level of c-Myc protein was determined by Western blot. RESULTS Both decitabine and anlotinib could effectively inhibit the proliferation and induce the apoptosis of MM cell lines NCI-H929 and RPMI-8226. The effect of combined treatment on the inhibition of cell proliferation and induction of apoptosis was stronger than that of single-drug treatment. The combination of the two drugs also showed strong cytotoxicity in primary MM cells. Decitabine and anlotinib could down-regulate the level of c-Myc protein in MM cells and the c-Myc level in the combination group was the lowest. CONCLUSION Decitabine combined with anlotinib can effectively inhibit the proliferation and induce apoptosis of MM cells, which provides a certain experimental basis for the treatment of human MM.

Abstract
OBJECTIVES To explore the effect of additional chromosomal abnormalities on the prognosis and outcome of CML-CP patients receiving imatinib therapy. METHODS The clinical and genetic data of 589 CML-CP patients receiving imatinib treatment between May 2009 and October 2014 in the 1st Affiliated Hospital of Soochow University were analyzed, the 589 patients were divided into 5 groups according to the karyotypes at the initial diagnosis. The OS(overall survival), PFS (progression-free survival), EFS (event-free survival), Cumulative MMR (major molecular remission) and Cumulative CCyR (complete cytogenetic remission) were calculated by using the Kaplan-Meier method and compared by using the log-rank text by Graphpad 6.0. The χ2 test was used to compare the frequency of optimal molecular response at 3, 6, 12 months among the 5 groups. RESULTS There was significant difference about the frequency of optimal molecular response at 3 and 6 months between CML-CP patients with additional chromosomal abnormalities and those with classic t(9;22) [50%(12/24) vs. 73.94%(261 /353), P<0.05; 50%(10 /20) vs. 72.05%(232 /322) (P<0.05)], and the same significant difference was found at 6 months between the group with variant translocations and that with classic t(9;22) [53.3% (16 /30) vs. 72.05%(232 /322) (P<0.05)]. The P values of cumulative CCyR (P<0.05) and EFS (P<0.01) for 4 years were statistically significant between CML-CP patients with additional chromosomal abnormalities and the other 4 groups. Compared one to another, there was the significant difference in cumulative CCyR and EFS for 4 years between CML-CP patients with additional chromosomal.abnormalities and those with classic t(9;22) (47.25% vs. 84.01%)(P<0.05); (75.03% vs. 90.01%)(P<0.01). CONCLUSION The additional chromosomal abnormalities influence the outcome of CML-CP patients receiving imatinib treatment, which make poor prognosis.

Abstract
We examined the variation in plasma levels of endothelin (ET), calcitonin gene-related peptide (CGRP), nitric oxide (NO), and malondialdehyde (MDA), as well as superoxide dismutase (SOD) activity, in acute myocardial ischemia reperfusion injury in a rabbit model. Seventy rabbits were randomly assigned into 3 groups. Open-chest surgery (OCS) was performed for all rabbits. Group A (N = 20) received sham-surgery, group B (N = 25) was the reperfusion group, and group C (N = 25) was the infarction group. At 12 h after chest clo-sure, plasma ET levels in groups B and C were clearly increased, while CGRP levels were clearly decreased, particularly in group B. At 24 h after chest closure, ET levels were higher than before OCS, while there was no significant difference between groups B and C. ET in group B was decreased, while that in group C was increased at 12 h. No significant difference in CGRP was observed between 12 and 24 h after chest closure. NO levels in groups B and C at 12 h after chest closure were significantly decreased compared to those before OCS. NO levels in group B at 24, 48, and 72 h were significantly lower than those at 12 h, while those of group C were not significantly changed after 12 h. Dynamic monitoring and comparison of plasma levels of ET, CGRP, NO, and MDA as well as SOD activity revealed that appropriate intervention of these factors may reduce reperfusion injury.

Abstract
Intercellular adhesion molecule-1 (ICAM-1) is an important factor in the progression
of inflammatory responses in vivo. To develop a new
anti-inflammatory drug to block the biological activity of ICAM-1, we produced a
monoclonal antibody (Ka=4.19×10−8 M) against human
ICAM-1. The anti-ICAM-1 single-chain variable antibody fragment (scFv) was expressed
at a high level as inclusion bodies in Escherichia coli. We refolded
the scFv (Ka=2.35×10−7 M) by ion-exchange chromatography,
dialysis, and dilution. The results showed that column chromatography refolding by
high-performance Q Sepharose had remarkable advantages over conventional dilution and
dialysis methods. Furthermore, the anti-ICAM-1 scFv yield of about 60 mg/L was higher
with this method. The purity of the final product was greater than 90%, as shown by
denaturing gel electrophoresis. Enzyme-linked immunosorbent assay, cell culture, and
animal experiments were used to assess the immunological properties and biological
activities of the renatured scFv.
