Objective To compare the clinical safety and efficacy of complete mesoeolic excision (CME) for right-hemi colorectal cancer with traditional surgical treatment.Methods Collectting the clinical data of 69 cases,who randonly divided into two groups,A group induced 38 cases and were implemented regular CME,and B group induded 31 cases which were implemented traditional surgery of right-hemi colorectal cancer patients from the Department of General surgery,Fuzhou General Hospital of Nanjing Military Region from Jan.1 2010 to Oct.1 2010,and comparing the safety and efficacy.Results The differences between and traditional surgery in terms of operation time,blood loss,exhaust and defecation time,hospitalization time,the rate of postoperative complication,the number of removed lymph node of Ⅰ and Ⅱ phase,3-year recurrence rate of Ⅱ phase,3-year survival rate of Ⅱ phase and the number of removed lymph node of Ⅲ phase in mesentery root were not significant.The differences in terms of the number of removed lymph node of Ⅲ phase(22.76 ± 6.94,15.11 ± 7.85),3-year recurrence rate of Ⅲ phase(5.88％,45.45％),3-year survival rate of Ⅲ phase (94.12％,63.64％),the total number of removed lymph node(20.56 ± 7.11,13.92 ± 6.62),3-year overall recurrence rate(7.89％,29.03％)and 3-year overall survival rate (94.74％,77.42％) were significant.Conclusions Comparing with traditional surgery,CME significantly benefits the patients of right-hemi colorectal cancer with stage Ⅲ,but not for patients with stage Ⅰ and Ⅱ.

Objective To investigate the effects of tissue specific cytosine deaminase/5-fluorocytosine (CD/5-FC) thermotherapy on hepatic metastasis of colonic carcinoma in nude mice. Methods Forty-five nude mice were randomly divided into control group, 5-FC group and 5-FC thermotherapy group according to the random number table (15 mice in each group). Mice models of hepatic metastasis of colonic carcinoma were established by portal vein injection of LoVo/CEACD cells. The hepatic metastasis rate and number of metastatic nodules of the 3 groups were compared by ehi-square test and one-way ANOVA. The pathological changes in tumor tissues and apoptotic index of tumor cells were observed. The expression of the CD gene in tumor tissues was detected by fluorescent quantitative RT-PCR and Western blot. Results The number of metastatic nodules and liver metas-tasis rate were 4.6±1.3 and 100.0% in control group, 2.2±1.0 and 60.0% in 5-FC group, 0.5±0.8 and 13.3% in 5-FC thermotherapy group, with statistical difference among the 3 groups (F=25.898, χ2=5.208, 19.548, 5.168, P<0.05). The mean apoptotic indexes of tumor cells of the 3 groups were 4.6%, 9.9% and 17.4%, respectively. Vacuolar degeneration, cell necrosis, cytolysis and apoptotic bodies were mostly observed in the 5-FC thermotherapy group. The expression of CD gene in tumor tissue was detected in all the groups. Conclusion Tissue specific CD/5-FC thermotherapy has inhibitory effects on the hepatic metastasis of LoVo cells transfected with CD gene.

Objective:To review the dual-time-point 18F-fluorodeoxyglucose (FDG) positron emission tomography/X-ray computed tomography (PET-CT) imaging for a patient with primary ureteric lymphoma (PUL),and explore the potential ofFDG PET-CT on diagnosis,staging and evaluation of treatment in patients with PUL.Methods:Complete clinical and imaging data of one patient with PUL was reported.The relevant literatures from 1997 to 2016 were reviewed,and the imaging features of uriteric lymphoma were analyzed.Results:The patient presented with microhematuria,a soft-density mass with moderate enhancement in the mid left ureter,and a luminal stenosis with the scope inserted 5 cm into the left stoma,but no mass was found.The patient was pathologically diagnosed as follicular lymphoma (stage IE confirmed by whole body FDG PET-CT).Conclusion:PET-CT may be useful in diagnosis,clinical stage and therapy assessment in patients with PUL.

Protein lysine methylation is a prevalent post-translational modification (PTM) and plays critical roles in all domains of life. However, its extent and function in photosynthetic organisms are still largely unknown. Cyanobacteria are a large group of prokaryotes that carry out oxygenic photosynthesis and are applied extensively in studies of photosynthetic mechanisms and environmental adaptation. Here we integrated propionylation of monomethylated proteins, enrichment of the modified peptides, and mass spectrometry (MS) analysis to identify monomethylated proteins in Synechocystis sp. PCC 6803 (Synechocystis). Overall, we identified 376 monomethylation sites in 270 proteins, with numerous monomethylated proteins participating in photosynthesis and carbon metabolism. We subsequently demonstrated that CpcM, a previously identified asparagine methyltransferase in Synechocystis, could catalyze lysine monomethylation of the potential aspartate aminotransferase Sll0480 both in vivo and in vitro and regulate the enzyme activity of Sll0480. The loss of CpcM led to decreases in the maximum quantum yield in primary photosystem II (PSII) and the efficiency of energy transfer during the photosynthetic reaction in Synechocystis. We report the first lysine monomethylome in a photosynthetic organism and present a critical database for functional analyses of monomethylation in cyanobacteria. The large number of monomethylated proteins and the identification of CpcM as the lysine methyltransferase in cyanobacteria suggest that reversible methylation may influence the metabolic process and photosynthesis in both cyanobacteria and plants.
