Objective To investigate the effects of nasojejunal feeding plus nasogastric tube decompression in severe hypertensive intracerebral hemorrhage complicated with gastroparesis.Methods Fifty-six cases of severe hypertensive intracerebral hemorrhage complicated with gastroparesis admitted to hospital from January 2011 to June 2014 were chosen as study group, while the 52 cases of similar patients admitted to hospital from January 2007 to December 2010 were chosen as control group.Nasojejunal feeding and nasogastric tube decompression were given to the study group.Nasogastric enteral nutrition support therapy was firstly given to the control group conventionally,after 15 days if they still could to be tolerant of the enteral nutrition,then parenteral nutrition therapy were adopted.The weight, serum albumin, prealbumin and hemoglobin circumstances of the two groups were determined and the complications were recorded.The patients were followed up according to activity of daily liying(ADL) after 3 months.Results There was no significant difference on the average body weigh between two groups before treatment.The average body weight of the study group was significantly higher than that of the control group after 4 weeks treatment((57.2±5.3) kg vs.(52.8±4.9) kg,t=4.33,P＜0.01).The serum albumin, pre albumin and hemoglobin of 3 week, four week after treatment were significantly higher than those of the control group(serum albumin of 3 week: (34.5±3.3) g/L vs.(30.7±3.1) g/L;erum albumin of four week:(37.8±3.8) g/L vs.(34.1 ± 3.4) g/L;serum prealbumin of 3 week:(202.3± 16.7) g/L vs.(179.6 ±15.2) g/L;serum prealbumin of four week: (216.9±17.1) g/L vs.(203.1±15.4) g/L;hemoglobin of 3 week : (119.4± 12.1) g/L vs.(107.7 ± 11.3) g/L;hemoglobin of four week : (126.2± 12.8) g/L vs.(113.5 ±11.9) g/L).Nutritional status of study group was significantly better than that of the control group(t=6.16, 5.32,7.37,4.85,5.18,5.32;P＜0.01), and complications was significantly less than that of the control group (P＜0.05).After three months, the good prognosis rate of study group (80.36％ (45/56)) was significantly higher than that of the control group (6 1.54％ (32/52)), the difference was statistically significant (x2 =4.67, P ＜0.05).Conclusion Nasojejunal feeding plus nasogastric tube decompression for patients with severe hypertensive intracerebral hemorrhage with gastroparesis can improve nutritional status, enhance their body resistance, reduce the incidence of complications, and improve their prognosis.

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.

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.

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).

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 <90 g/L group, Hb 90-99 g/L group, Hb 100-110 g/L group, Hb >110 g/L group, and also were albumin <25 g/L group, albumin 25-28 g/L, albumin 29-31 g/L group, 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), P<0.05. Multifactor Logistic regression analysis showed that albumin level was the relevant factor for the severe craniocerebral trauma (P<0.01), the hospital mortality was decreased with the rising of the albumin level, but the risk of death was higher in albumin>31 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.

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.

AIM: To investigate the effects of octreotide (Oct) on the proliferation and extracellular matrix (ECM) synthesis in hepatic stellate cells (HSCs). METHODS: HSCs were isolated from normal male Sprague-Dawley rat liver by a combination of pronase-collagenase perfusion and density gradient centrifugation. The concentration of 2.5 ?g/L transforming growth factor ?1 (TGF?1) was used in all the experiment settings. Oct at concentrations of 0.01 mg/L ,0.1 mg/L,1 mg/L and 10 mg/L,respectively,or 0.01 mg/L Oct + TGF?1,0.1 mg/L Oct+TGF?1,1 mg/L Oct+TGF?1,10 mg/L Oct+TGF?1 were respectively added to the cultured HSCs. Effects of Oct on HSC proliferation and ECM synthesis were respectively determined by MTT method,-TdR and -proline incorporation,or radioimmunoassay. RESULTS: Oct inhibited MTT intake by cultured hepatic stellate cells and down-regulated -TdR incorporation,compared with control group. The concentrations of hyaluronic acid,laminin,collagen type IV in the culture supernatant and -proline incorporation in HSCs were decreased by Oct. TGF?1 obviously up-regulated proliferation and ECM synthesis in cultured HSCs,and Oct significantly blocked these actions. CONCLUSION: Oct inhibited proliferation and ECM synthesis in cultured HSCs,and elicited the effects of anti-hepatofibrogenesis.
