Purpose: This study aimed to establish whether computed tomography (CT)–determined sarcopenia is a useful imaging biomarker for postoperative outcome in elderly colorectal cancer (CRC) patients, and construct sarcopenia-based nomograms to predict individual outcomes after surgery. Materials and Methods: CT imaging data of 298 elderly CRC patients who underwent surgery in 2012-2014 were retrospectively analyzed. Skeletal muscle mass was determined by CT, and sarcopenia was diagnosed based on the optimal cutoff value determined by X-tile program. The correlation between sarcopenia and risk of preoperative nutrition and postoperative complications was evaluated. A Cox proportional hazards model was used to determine survival predictors. Sarcopenia-based nomograms were developed based on multivariate analysis, and calibrated using concordance index and calibration curves. Results: A total 132 patients (44.3%) had sarcopenia based on the optimum cutoff values (29.9 cm2/m2 for women and 49.5 cm2/m2 for men). Sarcopenia was an independent risk factor for preoperative nutrition (p < 0.001; odds ratio [OR], 3.405; 95% confidence interval [CI], 1.948 to 5.954) and postoperative complications (p=0.008; OR, 2.192; 95% CI, 1.231 to 3.903). Sarcopenia was an independent predictor for poor progression-free survival (p < 0.001; hazard ratio [HR], 2.175; 95% CI, 1.489 to 3.179) and overall survival (p < 0.001; HR, 2.524; 95% CI, 1.721 to 3.703). Based on multivariate analysis, we produced four nomograms that had better predictive performance. Conclusion CT-determined sarcopenia is a useful imaging biomarker for predicting preoperative nutritional risk, postoperative complications, and long-term outcomes in elderly CRC patients. The sarcopenia-based nomograms can provide a scientific basis for guiding therapeutic schedule and follow-up strategies.

[Objective]To explore the evaluation value of ultrasomics based on contrast-enhanced ultrasound (CEUS)imaging in the therapy response of microRNA-122(miR-122)in hepatocellular carcinoma(HCC).[Method]Mice bearing subcutaneous HCC xenografts were injected intratumorally with microRNA-122 mimics(miR-122 mimics) and negative control mimics(NC mimics)in treatment group(n=6)and control group(n=6),respectively. The injec-tions were performed every 3 days for five times.Before each injection,two-dimension ultrasound(2D-US)imaging was performed.At 24 h after the last injection,2D-US and CEUS images of tumors were acquired,and then mice scarified for tumor miR-122 expression analysis by qRT-PCR.To evaluate the therapy response by RECIST,tumor volumes were mea-sured based on each 2D-US image. To analyze the tumor perfusion by mRECIST,perfusion parameters(maximum of intensity,rise time,time to peak,mean transit time,quality of fit)were analyzed off-line based on dynamic CEUS videos using SonoLiver?software. For ultrasomics,CEUS images at 10,30,60,90 second were used for features extraction, respectively. The corresponding ultrasomics formulas were built to evaluate the therapy response for miR-122.[Result]The tumors treated with miR-122 mimics resulted in a(763±60)folds increase in miR-122 levels compared to the tumors in control group(P<0.05).Effectively therapeutic response evaluated by tumor sizes change was detected after the third injection(P<0.05).For assessment using mRECIST,all the parameters of treatment group did not show significant difference from the ones of control group(P>0.05).Analysis using ultrasomics fail to detect different features of the static images of CEUS at 10 s,and models can be successfully built based on the rest of the three phases of CEUS images.The ultrasomics Scores between control group and treatment group were statistically different(P<0.05).The ultrasomics score at 30s were significantly lower than those at 60 s and 90 s,while there was no statistical difference between scores at 60 s and 90 s.[Conclusion]Ultrasomics analysis based on CEUS imaging is a useful method in evaluating the therapy response of miR-122 in HCC,and showed greater value than dynamic perfusion parameter.

Objective Clear cell renal cell carcinoma (ccRCC) accounts for more than 80% of malignant kidney tumors and its pathogenesis has not been elucidated. Our previous studies showed a positive correlation of Glucose-6-phosphate dehydrogenase (G6PD) with the development, progression and poor prognosis of ccRCC. In this study, we first established a G6PD defect ccRCC stable cell line, detected the influence of G6PD knockdown on ccRCC migration, and provided a cell model for further studies on the functional and molecular mechanisms of G6PD in ccRCC.Methods Using the OligoEngine RNAi software, we designed siRNA targeting the human G6PD gene 3′ non-coding region and negative control siRNA sequences, inserted the double-stranded siRNA into the pSR-GFP/Neo expression vector through Bgl Ⅱ and Hind Ⅲ enzyme loci, and constructed Caki-1-G6PD siRNA and Caki-1-negative control cell lines, followed by transfection and G418 screening of the Caki-1 cells. We measured the expression and enzyme activity of G6PD in the cells by real-time RT-PCR, determined the cell migration phenotypes by Transwell assay, and detected the expressions of p-STAT3 and STAT3 by Western blot.Results Morphologically normal Caki-1-G6PD siRNA and Caki-1-negative control cells were seen under the fluorescence microscope. With GFP expression as a marker, the transfection efficiency rate of the cells was 45－55%. The density of the adherent cells at 48 hours was 90% and their transfection efficiency rate was over 60%. Compared with the Caki-1-negative control cells, the Caki-1-G6PD siRNA cells showed significant decreases in the expressions of Caki-1-G6PD mRNA and protein (P<0.01), enzyme activity (P<0.05), relative count of migratory cells (64.0±4.2 vs 30.0±2.9, P<0.01), and the ratio of p-STAT3/STAT3 (0.45±0.05 vs 0.24±0.01, P<0.01).Conclusion The Caki-1-G6PD siRNA cell line with stable G6PD knockdown and a lower migration ability was first successfully constructed, and the decreased migration ability induced by G6PD knockdown is associated with the STAT3 signal, which is contributive to an insight into the functional and molecular mechanisms of G6PD in the development and progression of ccRCC as well as to finding intervention targets for the treatment of ccRCC.
