Objective To explore more reasonable way of early post-operative effect of enteral nutrition fluids support for colon cancer.Methods A total of 86 case of colon cancer were selected and assigned to enteral nutrition group(EN n=45)and parenteral nutrition group(PN n=41)randomly.Parameters inclu ding the body wetght,IsA,IgM,lymphocyte,human serum prealbumin and albumen were monitored on three days before operation,the fifth,and eighth days after operation.Results The IgA,IgM,lympho cyte,human serum prealbumin and albumen levels of patients in EN group were much higher than that in PN group on the fifth and eighth days after operation(P＜0.05).Also IgA,lgM levels of EN group patients were almost higher than that in PN group on eighth day after operation(P＜0.01).Concusions It showed that to perform enteral nutrient supports for patients of colon cancer during early post-operative could increase their gut immunity after operation and reduce the complications and raise human serum prealbumin and albu men of them for their body recovery.

The therapy based upon individuality is becoming a trend Oil general surgery field which has been highlighted by lots of specialists,scholars and clinic doctors,and so as the therapy of inguinal hernia.Along with the rushing appearoace of new idea and technique,the problem up to the minite which is confusing clinic doctors is how to select proper method of inguinal hernia therapy.This article is focused on the therapy of inguinal hernia based upon individuality.

Previous studies suggest that NGAL (neutro phil gelatinase-associated lipocalin) is involved in the transformation and development of esophageal carcinoma. Alteration of NGAL expression can trigger the change of cellular morphology in esophageal carcinoma cells. However, the mechanisms remain unclear. To get a better understanding of NGAL function in esophageal carcinoma, NGAL protein was expressed in methylotrophic yeast, Pichia pastoris, and purified by chromatography. EC1.71 cells expressed high levels of NGALR (NGAL receptor) and EC109 cells expressed low levels of NGALR were used as cells model. The trafficking and the possible function of NGAL protein were then analyzed in the esophageal carcinoma cells. The results showed that 5-FAM-labeled recombinant NGAL protein could internalize into the EC1.71 and EC109 cells. Furthermore, the internalized NGAL protein could induce the alteration of cellular morphology, resulting in generation of autophagosome, transcriptional up-regulation of genes associated with autophagy and increase of phospho-ERK1/2 (p-ERK1/2). Interestingly, the treatment with the NGAL protein did not affect the intracellular iron level. These data indicate that induced autophagy by exogenous NGAL protein is a mechanism that internalized NGAL plays important roles in esophageal carcinoma cells, independent with NGAL-mediated iron transport process, while ERK1/2 signal pathway is involved in activation of autophagy by exogenous NGAL protein.

Objective The aim of this study is to explore the hypoglycemic effect of active components of Anoectochilus roxburghii on zebrafish models. Methods Anoectochilus roxburghii components were extracted and separated into three groups: the alcohol extraction group, macromolecular polysaccharide group (≥ 5 ×103) and small molecular polysaccharide group (＜5×103). Zebrafish embryos were exposed to 2% glucose solution (2% Glu) at 24 h to imitate acute hyperglycemia phenotype, and then treated with the three Anoectochilus roxburghii components. Based on this high-glucose model, the zebrafish embryos at 72 h were collected to detect the whole tissue glucose value. Furthermore, semi-quantitative PCR and whole mount in situ hybridization were performed to detect the expression of mRNA levels of glycometabolism-related genes. Results An acute diabetic zebrafish model was induced by high glucose stress. In this model, some key factors during glycometabolism such as insulin, pck-1 and pdx-1 were significantly affected, while the alcohol extracts of Anoectochilus roxburghii obviously reversed these abnormalities induced by high glucose stress, even to normal levels. Conclusions The alcohol extracts of Anoectochilus roxburghii has obvious hypoglycemic effect on diabetic zebrafish model. Our result suggest that Anoectochilus roxburghii has a potential application in the hypoglycemic drug screening.

Objective:To investigate the possible role of long non-coding RNA (LncRNA) 00602 in promoting browning in adipocytes induced by adenovirus type 36 (Ad36).Methods:According to Ad36 infection, adipose tissue samples of obese patients were divided into Ad36-negative group and Ad36-infected group. Realtime fluorescent quantitative PCR (qRT-PCR) was used to detect the changes in the expression of LncRNA00602 mRNA in omental adipose tissue of the two groups, and analyze the differences between the two groups. The correlation between waist-to-hip ratio, systolic blood pressure, diastolic blood pressure, fasting blood glucose, triacylglyceride and other indicators of the patients in the group with LncRNA00602 mRNA expression were analyzed. HE staining was used to detect the size of adipocytes in the omental adipose tissue of the Ad36 negative group and the Ad36 infection group. qRT-PCR and Western blotting were used to detect the mRNA and protein expression levels of uncoupling protein 1 (UCP1) and PR domain containing 16 (PRDM16) in omental adipose tissue of two groups of patients. Human adipose-derived stem cells (hADSC) were isolated and cultured, using Ad36 to induce differentiation, and divided into control group and LncRNA00602 knockdown group. On 0, 2, and 4 days after LncRNA00602 knockdown, fluoroboron dipyrrole (BODIPY) and mitochondrial red fluorescence (Mito-Tracker Red) were used to stain intracellular lipid droplets and mitochondria. At the same time, qRT-PCR and Western blotting were used to detect changes in the expression of UCP1 and PRDM16.Results:The expression of LncRNA00602 gene in the Ad36 infection group was higher than that in the Ad36 negative group (all P<0.05). The expression of LncRNA00602 in the Ad36 negative group was not significantly different from the above clinical indicators, while the expression of LncRNA00602 was negatively correlated with serum fasting blood glucose and triacylglyceride ( r=-0.522, -0.486, P<0.05) in the Ad36 infection group; HE staining showed that the average adipocyte area of the Ad36 infection group was smaller than that of the Ad36 negative group. At the same time, UCP1 and PRDM16 gene expression were higher than the negative group (all P<0.05). At the cellular level, on the 2nd and 4th days after knockdown of LncRNA00602, the lipid droplet area of adipocytes in the LncRNA00602 knockdown group was larger than that of the control group, the number of mitochondria decreased compared with the control group, and difference was statistically significant ( P<0.05 or P<0.01); Compared with the control group, there was significantly lower expression of the browning marker genes UCP1, PRDM16, and protein in the adipocytes in the LncRNA00602 knockdown group (all P<0.05). Conclusion:In Ad36-induced adipocyte differentiation, LncRNA00602 may positively regulate the expression of UCP1, PRDM16 and lipid droplet metabolism, and promote the browning of adipocytes.
