The study on tumor metabolism has been gradually be-come a hot spot in recent years .A lot of proteins involved in the regulation of tumor metabolism especially the glucose transporter protein 1(GLUT1).As a key regulatory factor mediating energy metabolism within tumor cells , GLUT1 can regulate the glucose intake and maintain the basic level of metabolism in tumor cells . More importantly, the abnormal expression of GLUT1 was asso-ciated with many kinds of tumors , of which GLUT1 was used to meet the energy requirement for the fast growth of tumor .Thus GLUT1 also played a crucial role in growth , differentiation and metastasis of tumor cells and prognosis of tumors .Meanwhile , as three-dimensional crystal structure of GLUT 1 was determined , it is possible to design the small molecular inhibitors of GLUT 1, which can realize “starve to death” tumor cells.GLUT1 can be a particularly attractive target for tumor treatment and interfer-ence.The relationship between abnormal expression of GLUT 1 protein and tumor metabolism was reviewed . Moreover , the mechanism of tumor metabolism regulated by GLUT 1 protein ex-pression and treatment of cancers were discussed , which may provide references for future research and clinical treatment .

Meanwhile, MHC-B27 was proved positive in 25% (6/24) subjects with the male-to-female ratio of 1.2:1.CONCLUSION: The prevalence of SpA is 1.61% in Beijing urban area,and SpA mainly consists of ankylopoietic spondylitis and USpA.

Tumor metastasis is one of the important biological characteristics of malignant tumor,which is closely related with the prognosis of the cancer patients.High expression of ADAM8 in varieties of tumors was revealed in many recent studies,and such aberrant expression played a crucial role in regulating of tumor metastasis.Studies showed that overexpression of ADAM8 attenuated the intercellular adhesion effect,promoted tumor angiogenesis,and enhanced the degradation of ECM as well as the releasing of cytokines.Therefore,suppression of ADAM8 may lead to inhibition of tumor metastasis,which makes ADAM8 a particular attractive target as it can be used as a prognostic indicator and a potential therapeutic target of malignant tumor.A review about the relations between ADAM8 protein′s abnormal expression and tumor occurrence was discussed in this paper,also include discussion about the mechanisms of ADAM8 protein′s disorder-induced tumor formation,as well as therapeutic strategies based on ADAM8-targeted,which may provide references for follow-up research and clinical treatment.

This is a research project aimed at investigating the clinical efficiency of W-F168-B, a dialyzer reprocessing machine made by Weilisheng Biological Material Company in Chengdu, evaluating its effects on total cell volume (TCV) and dialysis sufficiency, and assessing its disinfection efficacy. All subjects were randomly divided into two groups, whose dialyzers were reprocessed by W-F168-B (made in Chengdu) and RENATRON II (made by MINNTECH Company in the United States) respectively. We detected TCV of the dialyzer before and after reusing and calculated their diversity. We also calculated all subjects' Kt/V. The values of TCV diversities of two groups were 5.5 +/- 4.15 (experimental group) and 4.5 +/- 2.56 (control group) respectively, P > 0.05. The levels of Kt/V of experimental group and control group were 1.25 +/- 0.26 and 1.24 +/- 0.19, P > 0.05. T-test showed that there was no statistically significance difference between the two groups. The result of every hemoculture is negative. In conclusion, these two dialyzer reprocessing machines are similar in the effect of the dialyzer's performance and the subject's dialysis sufficiency. The reused dialyzers reprocessed by these two machines are safe for use.

Objective:To compare the clinical effects of discectomy combined with transpedicular dynamic stabilization and transforaminal lumbar interbody fusion (TLIF) in treating single-level lumbar disc herniation.Methods:From November 2012 to November 2015, a total of 96 patients with single-level lumbar disc herniation (disc height decreased more than 1/3, the width of the basilar part of the herniated disc >6 mm, massive disc herniation or Modic type I endplate changes) treated by discectomy combined with Dynesys dynamic stabilization (Dynesys group, n=48) or TLIF (fusion group, n=48) were enrolled. Clinical assessments included operation duration, intraoperative blood loss, MacNab score, visual analogue scale (VAS), Oswestry disability index (ODI) and rate of complications. Radiographs were evaluated for lumbar mobility, intervertebral height, etc. Results:A total of 86 patients were included in the final analysis (44 in Dynesys group and 42 in fusion group) and were evaluated after 5 years follow-up. The operation duration of Dynesys group (159.61±37.29 min) was less than that of the fusion group (177.42±39.90 min) significantly ( t=2.140, P=0.035). Intraoperative blood loss in Dynesys group (151.78±50.88 ml) was less than that in fusion group (197.74±76.55 ml) with significant difference ( t=3.293, P=0.001). At 5 years follow-up, there were 2 cases with screw loosening and 5 cases with adjacent segmental degeneration in Dynesys group without symptom. In fusion group, there were 12 cases with adjacent segmental degeneration and two of them with symptom. There were significant differences in the incidence of adjacent segment degeneration between the two groups ( χ2=4.012, P=0.045). According to the MacNab criteria, excellent or good cases accounted for 95% in Dynesys group and 93% in fusion group without significant differences ( Z=0.425, P=0.671). VAS back, VAS leg and ODI scores were improved significantly in both groups after 2 years and 5 years ( P<0.05). However, there were no significant differences between the two groups ( P<0.05). The activity of the surgical segment was 4.59°±0.48° in Dynesys group and 1.00°±0.42° in fusion group at 5 years after surgery. The height of intervertebral space in Dynesys group decreased from 11.19±2.07 mm before surgery to 9.98±2.02 mm at 2 years after surgery and to 9.86±1.64 mm at 5 years after surgery ( F=6.462, P=0.002). However, there was no statistically significant difference between the 2 and 5 years follow-up ( q=0.415, P>0.05). At 5 years after surgery, the activity of the first proximal segment in the two groups was 9.74°±3.29° and 11.69°±3.89°, respectively ( t=2.514, P=0.014). Conclusion:Both discectomy combined with dynamic stabilization and TLIF can achieve satisfied clinical effects in treating single-level lumbar disc herniation. Dynamic stabilization preserves the intervertebral activity of surgical segments and results in a lower incidence of adjacent segment degeneration compared with that in fusion surgery. Furthermore, discectomy combined with dynamic stabilization is a less invasive intervention with shorter operation duration and less blood loss compared with TLIF.
