Proteomics was important for the coherent study of human reproduction and animal breeding including human infertility,sperm-egg binding and mutual recognition of the mechanism.It was well known that proteomics had become one of the main branches of life sciences in the future.This provides the technological means and theoretical foundation for the individual dynamic changes in the protein.At the same time,it plays an important role in the drug development,the mechanism of life activities and in the field of livestock breeding.

Objective To investigate the clinic effects of transcatheter arterial chemoembolization (TACE) combined with injection of hyper- thermic lipiodol into tumor body in treating large hepatic carcinoma. Methods A total of 86 patients with primary hepatic carcinoma were randomly and equally divided into the study group (n = 43) and control group (n = 43). TACE combined with injection of hyper-thermic lipiodol into tumor body was carried out in the patients of the study group , while only TACE was performed in the patients of the control group. The results were compared between the two groups. Results The effective rate of the study group and the control group was 68%and 53%respectively , and the difference between the two groups was statistically significant. The difference in the changes of tumor size after the treatment between the two groups was also statistically significant. In the study group, the survival rates at 6, 12, 18 and 24 months after the treatment were 100% (n = 43), 84% (n = 36), 53% (n = 23) and 33%(n=14) respectively, while in the control group the survival rates were 94% (n=40), 70% (n=30), 37%(n = 16) and 21%(n = 9) respectively. No statistically significant differences in postoperative liver function damage existed between the two groups. Conclusion TACE combined with injection of hyper-thermic lipiodol into tumor body is obviously superior to routine TACE in treating large hepatic carcinoma.

Objective To investigate the prognostic value of fever burden in traumatic brain injury (TBI) patients.Methods A retrospective analysis of 355 TBI patients admitted to the emergency department and intensive care unit from November 2010 to October 2012 was performed,and the Glasgow outcome scale (GOS) was followed-up 6 months after the injury.The patients were divided into two groups according to the GOS:good outcome group (4 to 5) and poor outcome group (1 to 3).Relevant clinical findings were studied by statistical description,logistic regression analysis,Spearman correlation analysis and ROC curve analysis.Results Fever burden level was continuously increased with the decrease of GOS from score 5 to 2,except for score 1 of GOS,which was corresponding to a significant lower fever burden.There were significant differences in age,pupil reactivity,Glasgow coma scale (GCS) and fever burden between two groups (P ＜ 0.05).Compared to the good outcome group,the poor outcome group was featured with more advanced average age (P =0.000),poorer pupil reactivity (P =0.000),lower GCS score (P =0.000) and higher fever burden level (P =0.000).Univariate logistic regression analysis suggested that age,GCS,pupil reactivity and fever burden level (OR 1.166,95％ CI:1.117-1.217) were associatedwith poor outcome.The fever burden level and the other independent prognostic predictors as age,GCS and pupil reactivity were further included in the multivariate logistic regression model,and the adjusted OR of fever burden level was 1.098 (95％ CI:1.031-1.169,P =0.003).ROC curve analysis showed the respective AUC for fever burden was 0.713 (95％ CI:0.663-0.760).The relevant analysis revealed a significant negative correlation between the fever burden and the GOS score (r =-0.376,95％ CI:-0.462--0.283,P =0.000).Conclusions Fever burden can be considered as an independent predictor of poor outcome of patients with TBI.The TBI patients with early onset of high levels of fever burden will have increased poor outcome risk.

Objective To prepare gadolinium-loaded stearic acid grafted chitooligosaccharide (COSSA-DTPA-Gd) and evaluate its micelle properties,cytotoxicity,relaxation rate in vitro,and pancreatic tumor in vivo imaging.Methods Stear ic acid grafted chitooligosaccharide (COSSA) was synthesized by acetylation reaction between stearic acid and chitooligosaccharide.Diethylenetriaminepentaacetic dianhydride (DTPA) was conjugated to the residual amino groups of COSSA,then Gd3+ was chelated to obtain the final product.The micelle properties were measured using an electron microscopy and a laser particle sizer.The MTT assay was adopted to determine cytotoxicity.The in vitro relaxation rate and in vivo imaging of pancreatic tumor were evaluated using an MR scanner.Results COSSA-DTPA-Gd could self-assemble into stable micelles in aqueous solutions with a critical micelle concentration of (5.12±0.43)μg/ml.The micelles had positive charge and exhibited roughly spherical shape with a mean diameter of (58.3± 5.7)nm.The content of Gd3+ in COSSA-DTPA-Gd was 330.31 μmol/g.The nanoprobe and Magnevist,the commercial formulation,showed similar cytotoxicity (P＞0.05).The cell survival rate within 24 h were higher than 85％.The in vitro relaxation rate of COSSA-DTPA-Gd was 8.23 mM-1 ·s-1.After intravenous injection,COSSA-DTPA-Gd showed a better positive contrast-enhancing effect for pancreatic tumor than Magnevist.The MR images at the tumor periphery was rapidly enhanced,while a slow increase in image quality was observed in tumor core.Conclusion The prepared COSSA-DTPA-Gd can be used for efficient MR imaging of pancreatic tumor.
