Objective:To study the early postoperative nutrition support of the liver transplantation.Methods:The early intake and nutrition were analysed in 44 patients with liver transplantation . The patients were divided into group A (22 patients , high amount of nitrogen inake ) and group B ( 22 patients , low amount of nitrogen intake ). The changes of the nitrogen balance,body weight, serum albumin, hemoglobin, serum lipids, renal function and liver function were evaluated.Results:There were no significant difference in body weight, serum albumin, hemoglobin, liver function between the two groups. The nitrogen balance of group A was better than that of group B,while the renal function of group B was better than that of group A.Conclusion:The amount of caloric and nitrogen intake in early postoperative stage of liver transplantation should be controlled.

Objective: To study the early postoperative nutritional support of the renal transplantation. Methods:The early intake and nutrition were analysed in 64 case who received the operation of renal transplantation. The patients were divided into group A (32 patients, high amount of nitrogen intake) and group B (32 patients, low amount of nitrogen intake) according to the different amount of actural nutritional intake during the period of postoperative three weeks. On the 21st day of post operation, the changes of the nitrogen balance, weight, albumin, hemoglobin, serum lipids and renal function were evaluated. Results:The nitrogen balance of group A was better than that of group B. But there was no significant difference in weight between the two groups. The level of serum albumin of group A was higher than that of group B. But there was no significant difference in hemoglobin level between the two groups. The level of Apro A of group A was higher than that of group B. The improvement of renal function of group A was less than that of group B. Conclusions:The result suggests that the amount of nitrogen intake in early stage of post operation of renal transplantation should be controlled so that the transplanted kidney could work better.

Objective Previous study found TGF-βpathway might be the molecular pathway influencing the prognosis of colo-rectal cancer, while it was uncertain whether Chinese population is associated with the disease.The article was to evaluate the genetic factors associated with prognosis in colorectal cancer. Methods 52 cases patients with colorectal cancer were followed-up for 36 months in our hospitals from January 2013 to August 2014.Their DNAs were extracted and stored and gene typing were carried out in 5 candidate genes to detect the association between SNPs and the prognosis in colorectal cancer. Results The results showed that within the TGF-βsignaling pathway, after adjusting for Bonferroni multiple testing, allele A of SNP rs10749971 located in gene POU2AF1 was associated with the recurrence of patients with stage III disease under additive and recessive genetic models ( HR =1.968, P=0.004;HR=2.174, P=0.010).Allele C of SNP rs961253 in the gene BMP2 could increase the recurrence risk (HR=1.992, P=0.005) and the death risk (HR=3.161, P=0.007) of patients with stage III disease under recessive genetic models.Allele A of SNP rs4464148 in SMAD7 gene could significantly decrease the death risk of patients with stage II and III colorectal cancer under dominant genetic model (HR=0.382, P=0.017;HR=0.230, P=0.006).In addition, accumulated effects of several adverse genes showed gene high risk group could increase the risk of death for patients with stage III colorectal cancer significantly ( HR=15.512, P=0.036;95%CI:1.611-149.360). Conclusion In different genetic models, SNP locus mutation within gene POU2AF1, BMP2 and SMAD7 on TGF-βpathway was associated with the prognosis of patients with colorectal cancer.With the increase of the number of unfavorable genes, the death risk increases accordingly.

Objective To determine the expression and distribution of Disabled-2(Dab2) in normal human adrenal glands, and further to study the expression of Dab2 in tissues of different adrenocortical adenomas, and to elucidate whether Dab2 can be a specific molecular marker in the pathology of primary aldosteronism. Methods Real-time PCR and immunohistochemical staining were used to detect Dab2 expression in 10 aldosterone-producing adenoma (APA) samples, 8 cortisol-producing adenoma ( CPA) samples, 8 non-functioning adenoma ( NFA) samples and 6 normal adrenal samples. Results Immunohistochemical staining showed that Dab2 was significantly highly expressed in zona glomerulosa of normal human adrenal glands. Sporadical cluster of ZG cells with moderate Dab2 staining were demonstrated in APAs. In all CPA and NFA tumors, weak dab2 staining was detected. According to the results of real-time PCR, Dab2 mRNA expression was increased significantly in APAs compared with normal adrenal glands. There was no significant difference between normal adrenal glands, CPAs, and NFAs in regard to Dab2 mRNA expression. Compared to nontumor portions, APAs also showed higher Dab2 mRNA expression in the tumor( P<0. 05). Conclusion Dab2 was predominantly localized in zona glomerulosa in normal adrenal gland. Increased Dab2 mRNA expression was detected in APAs compared with normal adrenal glands. Whereas, Dab2 protein expression was just moderate increased in APAs. Weather Dab2 can be a specific molecular marker in the pathology of primary aldosteronism has to be further studied.

Objective:
To investigate the effect of AKT1 deSUMOylation induced by Ubc9 silencing on the proliferation and metastasis of hepatocellular carcinoma (HCC) cells.
Methods:
The Ubc9 gene was silenced using RNA interference, and the expression levels of Ubc9, SUMO1 and AKT1 protein were detected by Western blot. Cell proliferation and cell cycle was analyzed by MTT and flow cytometry. Wound healing and transwell assays were used to detect the cell migration ability. Furthermore, the xenograft model was established, and tumor growth curves were drawn. The in situ apoptotic rates was measured using TUNEL Apoptosis Assay. The expression of proliferating cell nuclear antigen (PCNA), matrix metalloproteinase (MMP)-2 and MMP-9 were evaluated by immunohistochemical staining.
Results:
Knockdown of Ubc9 gene significantly decreased the protein expression levels of Ubc9, conjugated SUMO1, free SUMO1 and AKT1 in HCC cells (
