Objective:To investigate the serum level of miR-224 in hepatocellular carcinoma (HCC) patients and its clinical diag-nostic significance. Methods:The serum level of miR-224 was detected by real-time quantitative PCR. This study included 42 cases of patients with HCC, 36 patients with liver cirrhosis (LC), 55 patients with chronic hepatitis B (CHB), and 40 healthy persons (NC). The relative expressions of miR-224 were calculated. The receiver operating characteristic (ROC) curves were analyzed to determine the sensitivity and specificity of miR-224 expression levels in HCC diagnosis. Results:Result shows that the relative miR-224 expression was higher in the serum of HCC patients than that in the CHB, LC, and NC groups. The difference was statistically significant (P<0.05 or P<0.01). The relative miR-224 expression in the serum of HCC patients and alpha fetoprotein (AFP) were positively correlated (P<0.05). By comparison, the tumor size, TNM stage, tumor differentiation, and lymph node metastasis were not correlated with mirR-224 expression (P>0.05). ROC analysis shows that the best critical value of the relative expression levels of miR-224 was 3.47, with sensi-tivity of 82.2%, specificity of 92.8%, and area under the curve of 0.935. Conclusion:The serum level of miR-224 in HCC patients has high specificity, and miR-224 has great potential to become a new serological marker for the diagnosis of HCC.

Objective:To explore the histogenesis and differentiation of dermatofibroma (DF) and dermatofibrosarcoma protuberans (DFSP). Methods: Clinical information and microscopic characteristics of 26 cases of DF and 26 cases of DFSP were investigated. The immunohistochemical study was performed on microarray sections by a panel of antibodies including FactorⅩⅢa, HLA-DR, CD34, CD14, S-100, MSA, and Ki67. Probe was labeled by in vitro transcription. The mRNA expression levels of TGF-? and bFGF were investigated by in situ hybridization. Results: All cases showed positive for Factor ⅩⅢa,HLA-DR and CD34 to different extent. The medians of positive rates in DF were FactorⅩⅢa 90%, HLA-DR 70%, and CD34 5%, and in DFSP were FactorⅩⅢa 10%, HLA-DR 5%, and CD34 80%. CD14 was positive in 3 cases of DF and 1 case of DFSP. S-100 was positive in 6 cases of DFSP and 2 cases of DF. MSA was positive in 5 cases of DFSP and 3 cases of DF. In all cases, positive rate of Ki67 was less than 5%. The mRNA expression levels of TGF-? was elevated in DF in comparison with DFSP. Conclusion: Both DF and DFSP can differentiate to dendritic cells (DC) in different degree. Considering the character of microscopic features and immunohistochemical phenotype, cells of DF are much similar to mature DC, while those of DFSP much similar to immature dermal reserve cell (DRC). The differences of cell differentiation between DF and DFSP result in different prognosis. DF is a benign tumor, while DFSP a low grade malignant tumor. The different expression of FactorⅩⅢa and CD34 may be helpful to differential diagnosis of DF and DFSP.

Rare sugars were defined as monosaccharides and their derivatives that rarely exist in nature. They played an important role in food, health, medicine and etc A strategy for bioproduction of rare sugars, namely Izumoring, was described. By the Izumoring method, all monosaccharides and polyols could be linked, using enzymatic reaction with D-tagatose 3-epimerase, aldose isomerases and polyol dehydrogenases. Izumoring for hexoses, pentoses and tetroses were designed respectively. According to this strategy, the bioproduction routes of various rare sugars, using microbial and enzymatic reactions, could be obtained. In addition, the future research tendency of biotransformation of rare sugars was put forward.
