Objective To know the status of microbial contamination in filtrated water and edible ice used in food processing,and to provide experimental basis for the management of HACCP of filtrated water and edible ice. Methods The samples of water and ice were collected from a western style restaurant in Changchun. The microbial indicators were tested based on Standard Examination Methods for Drinking Water(2001). Results Results In the third quarter, 37.8%, 32.4%, 13.5% of total bacterium counts, total coliform counts, feces coliform counts of the water samples was unqualified. Conclusion The filtrated water and edible ice used in restaurants can be contaminated by microbes in degree. It is necessary for HACCP of filtrated water involved coliform counts contamination to carry out dynamic monitoring.

Objective To investigate the effects of allogenic intra-bone marrow bone marrow transplantation (IBM-BMT) on re-establishing hematopoiesis in mice. Methods Bone marrow mononuclear cells (BMNCs) from BALB/ c mice were transplanted into the C57BL/6 mice treated with a lethal dose of ~(60)Coγ-ray radiation through intra-bone marrow injection or intravenous injection. Sixty of the C57BL/6 mice were randomly divided into three groups as higher dose intra-bone marrow injection group (IBM1 group), lower dose intra-bone marrow injection group (IBM2 group) and intravenous injection group (IV group). The nucleated cell numbers of whole bone marrow from the tibia of each recipient mouse were counted respectively at the day 1, day 3, day 6 and day 9 after the transplantation. The donor-derived total nucleated cells and myeloid cells were quantified by flow cytometry. Results At 6th day after transplantation, more total bone marrow nucleated cells, total donor-derived nucleated cells and donor-derived myeloid cells in the tibia of injected side in both IBM1 group and IBM2 group were found than that in IV group (P<0.05 or P<0.01). Conclusion Compared with traditional bone marrow transplantation (IV-BMT),IBM-BMT improves the bone marrow hematopoiesis in the early hematopoietic re-establishing stage in allogenic bone marrow transplantation.

Objective To analyze the effect of cervical.curvature and intervertebral height on the surgical outcome of posterior decompression in patients with multi-level cervical spondylotic myelopathy.Method A total of 50 patients with multi-segment cervical spondylotic myelopathy (≥ 3 segments),treated with posterior decompression from June 2006 to January 2009 were retrospectively analyzed.Twenty six patients underwent cervical omni-posterior decompression and lateral mass screw internal fixation (group A); 24patients underwent expansive open-door laminoplasty (group B).The effects of changing of cervical curvature and intervertebral height on JOA score and VAS score were analyzed.Results All patients were followed up for 8 months to 4 years (average,24 ±5.5 months).There were statistical differences of cervical curvature angles between preoperative and 3 days postoperatively in group A,while no statistical differences in group B.There were no statistical differences of cervical curvature angles between 3 days,6 months and 3 years postoperatively in group A,while there were differences in group B After further analysis of the loss of cervical curvature and intervertebral height,the result showed that JOA score and VAS score in the low-loss group were better than those in the high-loss group.Conclusion Lateral mass screw internal fixation after cervical omni-posterior decompression had many advantages such as reducing the change of cervical curvature,the loss of intervertebral height and incidence of cervical axial symptoms.

Objective Hepatocellular carcinoma with bile duct tumor thrombus (BDTT) is rare,and surgical treatment is currently considered as the most effective treatment.Whether resectional surgery should be carried out on these patients remains controversial.Therefore,this Meta-analysis aimed to find out the long-term survival after resectional surgical treatment.Methods We conducted a literature search on PubMed,Embase and Web of Science from inception to September 2016.11 studies were included which involved 5295 patients.Each study was evaluated using the Newcastle-Ottawa Scale.The pooled effect was calculated and the associations between BDTT and overall survival (OS) or disease-free survival (DFS)were reevaluated using Meta-analysis with hazard ratio (HR) and 95％ confidence interval (CI).Results The HR for OS and DFS was 2.34 and 1.81,the 95％ CI were 1.26 ～ 4.36 and 1.17 ～ 2.78,respectively.Conclusion HCC patients with BDTT had a bad prognosis after hepatic resection or liver transplantation.
