Recent studies reported that thymoquinone (TQ), a component derived from the medicinal spice Nigella sativa (also called black cumin), exhibited inhibitory effects on cell proliferation of many cancer cell lines. This study was performed to investigate the anti-metastatic effect of thymoquinone on the pancreatic cancer in vitro and in vivo. The results showed that thymoquinone suppressed the migration and invasion of Panc-1 cells in a does-dependent manner. To investigate the possible mechanisms involved in these events, Western blotting analysis was performed, and found that thymoquinone significantly down-regulates NF-kappaB and MMP-9 in Panc-1 cells. In addition, metastatic model simulating human pancreatic cancer was established by orthotropic implantation of histologically intact pancreatic tumor tissue into the pancreatic wall of nude mice. And administration of thymoquinone significantly reduced tumor metastasis compared to untreated control. Furthermore, the expression of NF-kappaB and MMP-9 in tumor tissues was also suppressed after treatment with thymoquinone. Taken together, the results indicate that thymoquinone exerts anti-metastatic activity on pancreatic cancer both in vitro and in vivo, which may be related to down-regulation of NF-kappaB and its regulated molecules such as MMP-9 protein. Consequently, these results provide important insights into thymoquinone as an antimetastatic agent for the treatment of human pancreatic cancer.

[Objectives]To investigate the protective effects of recombinant Trichinella spiralis excretory-secretory 53ku pro-tein(rTsP53)on acute lung injuries in mice.[Methods]Thirty Balb/c mice were randomly divided into normal group. ALI group and rTsP53 group(n=10,respectively). Macrophages were harvested by bronchoalveolar lavage. Mortality in 72 hours was counted and compared. Pathological damage of lung tissues was observed by HE staining and graded by Smith score. Wet/dry ratio was measured. The bronchoalveolar lavage fluid concertration of IL-6 and IL-4 was measured by ELISA. The mRNA expression of TNF-α,iNOS, IL-10 and Arg-1 in alveolar lavage macrophages was detected by RT-PCR.[Results]72 h mortality of ALI mice was 70%,which was reduced to 30% in mice received rTsP53 treatment. Compared with ALI mice,the pathological damage of in rTsP53 treated-mice was improved and Smith score was declined ,combined with descending W/D ratio. IL-6 level of alveolar lavage fluid was elevated in ALI mice compared with normal group. And alveolar lavage macrophage was polarized to M2 sub-type,appeared as higher mRNA expression of TNF-α and iNOS and lower level of IL-10 and Arg-1. Bronchoalveolar lavage fluid concentration of IL-6 was declined and IL-4 was elevated in rTsP53-treated mice compared with ALI group. The macrophages of alveolar wash had higher mRNA expression of IL-10 and Arg-1,while lower level of TNF-α and iNOS,manifesting M2 polarization characteristics.[Conclusion]Recombinant T.spiralis P53 protein could protect mice from acute lung injuries induced by LPS via modulating M2 macrophage polarization,which play a role in depression of inflammatory reaction and tissue repairment.

Actinobacillus succinogenes is a promising candidate for the production of bio-based succinic acid. Previously, we isolated a succinic acid-producing strain Actinobacillus succinogenes CGMCC 1593 from bovine rumen. In this paper, the influence of the environmental factors such as gas phase, pH, ORP, on succinic acid production by A. succinogenes CGMCC 1593 was studied. The results showed that CO2 was the optimum gas phase for anaerobic fermentation ofA. succinogenes CGMCC 1593 as well as one of the substrate for the succinic acid synthesis. Using MgCO3 as a pH regulator, the pH was maintained within 7.1-6.2 during the anaerobic fermentation for the cell growth and acid production of A. succinogenes CGMCC 1593. Our results showed that low initial ORP was disadvantageous for the growth of A. succinogenes CGMCC 1593 and an ORP of -270 mV was demonstrated to be beneficial to the succinic acid production. By adding Na2S.9H2O to decrease ORP to -270 mV at the end of exponential growth phase in batch culture of A. succinogenes CGMCC 1593, the succinic acid concentration reached 37 g/L and the yield of succinic acid was 129% at 48 h. This work might provide valuable information for further optimization of succinic acid fermentation by A. succinogenes CGMCC 1593.

Objective:
To investigate the clinical efficacy of minimally invasive plate oseoynthesis (MIPO) assisted by a self-designed lower limb axial tractor in the treatment of complex tibial plateau fractures.
Methods:
The data were retrospectively analyzed of the 31 patients who had undergone surgical treatment for complex tibial plateau fractures from June 2015 to April 2018 at Department of Orthopeadics, Hospital Affiliated to Binzhou Medical College. MIPO was conducted with the assistance of the axial tractor in 17 of them. They were 12 men and 5 women with an age of 50.8±14.7 years, with 8 cases of Schatzker type Ⅴ and 9 ones of Schatzker type Ⅵ. MIPO was conducted without the assistance of the axial tractor but with the assistance of manipulation reduction in the other 14 patients. They were 9 men and 5 women with an age of 48.9±9.5 years, with 6 cases of Schatzker type Ⅴ and 8 ones of Schatzker type Ⅵ. The 2 groups were compared in terms of operation time, intraoperative bleeding, and Rasmussen scores for knee function and medial angle of the proximal tibia at the last follow-up.
Results:
The 2 groups were comparable due to insignificant differences in the preoperative general data between them (
