RESUMEN

The latest epidemiological data suggests that the situation of adult diabetes in China is severe, and metabolic diseases have become significant chronic illnesses that have a serious impact on public health and social development. After more than six years of practice, the National Metabolic Management Center(MMC) has developed distinctive approaches to manage metabolic patients and has achieved a series of positive outcomes, continuously advancing the standardized diagnosis and treatment model. In order to further improve the efficiency, based on the first edition, the second edition guideline was composed by incorporating experience of the past six years in conjunction with the latest international and domestic guidelines.

RESUMEN

OBJECTIVE:To establish a method for the concentration determination of vitamin A(VitA)in human serum,and apply it in healthy volunteers and hepatocirrhosis patients. METHODS:After liquid-liquid extraction,serum sample was deter-mined by HPLC. Using VitA acetic ester as internal standard,the separation was performed on Kromasil C18 column with mobile phase consisted of methanol-water (98∶2,V/V) at the flow rate of 1 ml/min. The wavelength was set at 325 nm,and the column temperature was room temperature. The sample size was 20 μl. RESULTS:The linear range of VitA were 0.012 4-3.210 μg/ml(r=0.997 2,n=5),and the limit of quantification was 0.012 4 μg/ml. Inter-day and intra-day RSD ranged 1.66%-2.97%;sample re-coveries were 98.18%-99.56%;extraction recoveries were 89.59%-91.38%. Average blood concentration of VitA were(0.71±0.08)μg/ml in 24 healthy volunteers and (0.28 ± 0.06)μg/ml in 24 hepatocirrhosis patients. There was statistical significance in average blood concentration of VitA between healthy volunteers and hepatocirrhosis patients in different age groups (P<0.05). CONCLU-SIONS:The method is simple,rapid,sensitive and accurate,and can be used for the concentration determination of VitA in serum of healthy volunteers and hepatocirrhosis patients.

RESUMEN

High expression of Fightless I (FLII) is associated to multiple tumors. Based on our previous study that FLII might be involved in the nuclear export, we assessed the possible interaction of FLII with the nuclear envelop associating proteins Importin β and Nup88. We first constructed GST-FLII, GST-LRR recombinant plasmids and transformed them into the Rosetta strain to produce GST-FLII, GST-LRR fusion protein. After purification of these proteins, GST-pull down, as well as co-immunoprecipitation, were used to test the interaction of FLII with Importin β and Nup88. FLII interacted with Importin β and Nup88, and FLII LRR domain is responsible for these interactions. Thus, FLII may play a role in nuclear export through interaction with Importin β and Nup88.

RESUMEN

OBJECTIVE: To establish the quality stangard of Erkening misture.METHODS:Raphanus sativus and Fritillaria thunbergii were identifided by TLC, and the content of the Baicalin in Erkening misture was determinated by HPLC. RESULTS: The TLC spots of Raphanus sativus and Fritillaria thunbergii were distinctive. The linear range of Baicalin was 0.319~2.64 ?g (r=0.999 3). The average recovery was 99.56%, and RSD was 0.83% (n=9). CONCLUSION: This established standard can be used for the quality control of the Erkening misture.
