ABSTRACT
Objective To investigate the change of serum pentraxin3 level in different body mass indices groups among the patients with type 2 diabetes mellitus(T2DM) and to analyze its correlation with metabolic indices.Methods A total of 164 T2DM patients were divided into the normal body mass group (A,n=53),over-weight group (B,n=56) and obese group(C,n=55) according to BMI.Serum pentraxin3 level was assayed by ELISA.Then the relationship between serum pentraxin3 levels with BMI.blood glucose,blood lipid andHOMA-IR was analyzed.Results The pentraxin3 levels in the group A,B and C were (3.46±0.19),(2.47 ± 0.21),(1.44 ± 0.18) ng/mL respectively,the pairwise comparison among three groups showed the statistical difference (P＜0.05).The pentraxin3 level was negatively correlated with BMI,TG,LDL-C,FINS and HOMA-IR (r=-0.897,0.621,-0.232,-0.593,-0.487,P＜0.05 or P＜0.01).The multiple stepwise regression analysis showed that BMI and HOMA-IR were independently correlated with serum pentraxin31evel.Conclusion BMI and HOMA-IR are the independent risk factor for af fecting serum pentraxin3 level in T2DM patients.
ABSTRACT
OBJECTIVE@#To analyze and summarize clinical characteristic, treatment scheme and survival rate of primary melanom in nasal cavity and sinus.@*METHOD@#We retrospectively analyzed the 9 patients with primary melanom in nasal cavity and sinus who in data proceed were treated and reviewed the related literature.@*RESULT@#Among the 9 patients, the clinical main symptoms are rhinostegnosis of lateral nasal and intermittent nasal bleeding. Pathologic examination is mainly characterized by tumor cells abnormity and cytoplasm containing pigment or without pigment, and main diagnosis basis is some or all of the positive for HMB45, S-100, melan-A. The survival rate are 88.9% (8/9) of 1-year, 66.7% (6/9) of 3-year and 33.3% (3/9) of 5-year.@*CONCLUSION@#The incidence of primary melanom in nasal cavity and sinusis is not frequent in clinic and confirmed by immunohistochemical. The extensive radical excision of focus and combine adjuvant radiotherapy postoperative may improve the survival rate of patients.

There are 13 members of the Let -7 miRNAs family which is regarded as tumor suppressor gene, locating in nine different chromosome loci. Lin28 acts as negative regulatory factor of miRNA biological recurrence. By selectively blocking the processing synthesis of the Let-7 miRNAs family, Lin28 block the inhibition effect of miRNA of proto-oncogenes and interact with RNA helicase to enhance gene translation at the same time. By not quite clear mechanism, an up-regulation of Let-7 inhibits the expression and function of Lin28. In more and more studies of human tumor, Lin28/Let-7 axsis was proved to be important significance of the tumor's occurrence and development. In this paper, we research briefly the recent progress of the molecular mechanism and related influence factors of ILin28/Let-7 axsis.
