ABSTRACT
Circular RNA (circRNA) is a widely present endogenous noncoding RNA that is covalently bonded at the 3' and 5' ends via trans-splicing to form a closed-loop structure with high stability, biological evolutionary conservatism,and tissue expression specificity. CircRNA has important biological functions, such as playing the role of microRNA (miRNA) sponge, regulating the expression of a par-ent gene, and improving transcription and translation levels. In gastrointestinal tumor, circRNA mainly plays the role of miRNA sponge, which affects the proliferation, differentiation, apoptosis, and invasion of cancer cells. In addition, circRNA was specifically expressed in the tumor, and the expression level significantly differs from that of paracancer. Therefore, a highly conserved and stable circRNA se-quence is expected to be an early diagnosis and prognostic marker for gastrointestinal tumor. In this study, we review research advanc-es on circRNA and its relationship with gastrointestinal cancers (esophageal, gastric, colorectal, and liver cancers).
ABSTRACT
Objective To investigate the relationship between plasma albumin and hemoglobin(Hb) levels and prognosis in patients with severe craniocerebral trauma. Methods The clinical data of 124 patients with severe craniocerebral trauma form January 2010 to January 2014 were analyzed retrospectively. The relationship between plasma albumin and Hb levels and prognosis were analyzed. Hb level was obtained in 3 days of admission, and then the patients were divided into Hb 110 g/L group, and also were albumin 31 g/L group according to the mean albumin level. Multifactor Logistic regression analysis was used to analyze the relationship between Hb, albumin levels and prognosis. Results Among 124 patients, 37 patients (29.8%) were given red blood cell (RBC) transfusion, and 28 patients (22.6%) received albumin treatment. The hospital mortality was 20.2% (25/124). The age, scores of Glasgow Coma Scale (GCS) and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ ), and hospital mortality in different Hb level groups had no significant differences (P>0.05). The age, scores of GCS score and APACHEⅡ score in different albumin level groups had no significant differences (P>0.05), but the hospital mortality in different albumin level groups had significant difference: 31.2%(10/32), 24.2%(8/33), 9.7%(3/31), 14.3%(4/28), P31 g/L group than that in albumin 29-31 g/L group. Conclusions 29-31 g/L albumin level is the best for severe craniocerebral trauma patients. There is no significant impact of Hb on the prognosis for severe craniocerebral trauma patients.

ABSTRACT
AIM: To study the effects of dietary factor on liver gene expression profile in apoE~(-/-)/LDLR~(-/-)/Lepr~(db/db) mice and atherogenesis. METHODS: The gene expression profile was determined by using cDNA microarray. Total plasma TC and TG level were measured with COD-PAP and GPO-PAP methods respectively. The morphological characters of the aorta were also observed. RESULTS: Among the 4000 target genes, 78 and 114 genes were up-and down-regulated, respectively, in treble genes mutants fed with high fat high cholesterol diet compared with that of regular chow littermates, including lipid metabolism, carbohydrate, cell skeleton and immune related genes. Atherogenic diet induced severe plasma hyperlipidemia even in the early stage and also accelerated atherogenesis in the treble genes mutant mice. CONCLUSION: The data suggest that atherogenic diet aggravates abnormal plasma lipid metabolism and induces severe hyperlipidemia, and atherogenesis in the treble genes mutant mice as well.

ABSTRACT
The effects of high concentrations (1-5mmol/L) of different amino acids in Hanks solution on the proliferation of Ehrlich ascites tumor cells and Walker 256 carcinosarcoma cells were examined. In order to demonstrate the inhibitory effect of some amino acids at high concentration level, the further studies were conducted on Ehrlich ascites tumor cells, human hepatoma cells and lung cancer cells, using Eagle's MEM as culture medium. The possible toxicity of the high concentrations of single amino acids to normal tissue cells was tested on mouse bone marrow cells. Although some amino acids exhibited a significant inhibitory effect, the responses of different tumor cells to the high concentrations of different amino acids were not entirely similar. Moreover, the effects presented by some amino acids on Ehrlich ascites tumor cells in Hanks solution could be diminished or eliminated in Eagle's MEM. Among the aromatic and basic amino acids, only the tryptophan was found to be inhibitory to the multiplication of mouse bone marrow cells at high concentration levels in vitro.
ABSTRACT
In the present study, an amino acid mixture had been prepared from whole swine blood by acid hydrolysis, ion-exchange separation and adequate supplementation of L-Trp, L-Met, and L-Ile. The content of essential amino acid, chemical score and essential amino acid index of the product were 49.33, 63.77, and 92.38% respectively and its essential amino acid pattern was closely similar to casein or whole egg protein with sulfur-containing amino acid as its first limiting amino acid. In the rat growth experiment, its nutritional value had been proved to be comparable with casein and better than swine blood powder itself in terms of weight gain, PER, and NPR. Therefore, this amino acid mixture can be considered as an ideal food additive and nitrogen source for elemental diet and this is an important way in the utilization of swine blood.
ABSTRACT
An elemental diet, commercially named Elementalio, contains an amino acid mixture and many other essential nutrients. The amino acid mixture is prepared from hydrolysis of swine blood and supplemented with certain crystalline L-amino acid. The animal experiments suggest that it has a better nutritional effect than other domestic elemental diets in terms of body weight gain, nitrogen balance and correction of hypoproteinemia.
