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.

Background Epithelial-mesenchymaltransition (EMT)isamajorcontributortothe pathogenesis of posterior capsular opacification(PCO).Kruppel-like factor 6 (KLF6) is a zinc finger protein,which can be stimulated by high glucose in proximal tubule cells and involved in transforming growth factor beta (TGF-β)induced EMT of diabetic nephropathy.ObjectiveThis study was designed to investigate the effect of high glucose on the expression of KLF6 and its target genes( TGFB1,TGFBR1,COLIA1,HSP47) in human lens epithelial cells (LECs).MethodsHuman LECs(SRA01/04) were cultured and exposed to different concentration of glucose.The expressions of KLF6 mRNA and protein were analyzed by real time polymerase chain reaction( real time PCR) and western blot after treatment with high glucose.The expressions of KLF6 target genes were analyzed by real time PCR to evaluate the EMT of SRA01/04 cells.ResultsCompared with the control group(5.5 mmol/L),the relative mRNA levels of t-KLF6 and wt-KLF6 in SRA01/04 treated with high glucose(22.2,44.4,66.6 mmol/L) increased obviously (F =72.53,42.02,P＜0.01 ).Then,the concentration of 22.2 mmol/L was used in the next experiments.The relative mRNA levels of t-KLF6 and wt-KLF6 increased to the peaks after treatment with high glucose for 12 h,and began to decrease after 24 h until lower levels after 48 h ( F =100.12,125.52,P ＜ 0.01 ).Western blot showed that the expression of KLF6 protein was also upregulated by high glucose treatment.With the promotion of the expression of KLF6 gene,the relative mRNA levels of TGFB1,TGFBR1,COLlAl and HSP47 of treated cells also respectively increased after treatment for 12 h,and began to decrease after 24 h until nearly at the levels of the control groups after 48 h( F=6.73,162.35,64.39,12.05,P＜0.05 ).ConclusionsIt was concluded that high glucose induced the expression of KLF6 in human LECs,and KLF6 transiently stimulated the expression of target genes TGFB1,TGFBRl,COLlAl and HSP47 which were mainly involved in the mechanism of EMT.

Objective: To obtain the data of dental measurements in healthy Mongolia teenages.Methods: Normal dentognathic models were obtained by cephalometric roentgenography in 56 teenages (30 boys and 26 girls) aged 10～17 years. The width of the tooth crown, the size of the dental arch and dental base bone were measured with a vernier. The measurments were statistically analysed.Results: The tooth crown in boys was wider than that in girls( P 0.05). There was no significant difference in Bolton index and Point index between boys and girls.Conclusion: The dental measurments may be refrences for dental clinic and research.

Development of liver fibrosis is closely associated with angiogenesis and abnormal vascular remodeling. Recent studies have highlighted the importance of angiogenesis and vascular remodeling in fibrogenesis, the results that inhibition of angiogenesis is effective in suppression of liver fibrosis demonstrate that therapies with several molecular targets against angiogenesis, inflammation and fibrosis might be beneficial for the treatment of cirrhosis. However, there is some evidence that inhibition of angiogenesis can even worsen fibrosis. This article outlines recent advances regarding the interplay between inflammation, angiogenesis and fibrogenesis in terms of cellular and molecular mechanisms, and suggests a requirement of greater understanding to intervene in these key processes, such as liver sinusoidal endothelial cell fenestration and impact distinct chemokine actions driving monocyte migration and differentiation, for therapeutic benefit in the future.

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.

AIM: To study the allergic disease in recurrent tonsillitis. METHODS: Immunohistochemical technique was used to investigate interleukin-4(IL-4) production in tonsil. RESULTS:The result showed that: a higher incidence of IL-4 producing cells were found in the tonsils of all ages, and a high density of IL-4 was found in the reticular crypt epithelium and extrafollicular, but low density in germinalcenter. IL-4 has been shown play a crucial role in the pathogensis of allergic disease. CONCLUSION:Allergic disease is an important reason of recurrent tonsillitis. The conclusion will give a new way to cure recurrent tonsillitis.

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.
