Objective To compare the positioning accuracy between personalized polyurethane foam with wing boards and negative pressure vacuum bag in radiotherapy for lung cancer using kilovoltage cone beam computed tomography(CBCT). Methods Thirty-nine patients with lung cancer who received chest radiotherapy in our hospital from 2015 to 2016 were enrolled as subjects. In those patients, 20 were immobilized by negative pressure vacuum bags(VB group)and the others by personalized polyurethane foam with wing boards(PF group).CBCT images were acquired weekly and registered with planning CT images. Setup errors in the left-right, superior-inferior, and anterior-posterior directions, three-dimensional(3D) displacement vector,and setup time were recorded. The margin of the planning target volume(PTV)was calculated using the Van Herk formula(2.5∑+0.7σ). Between-group comparison was made by paired t test. Results The PF group had a significant smaller setup error in the y-direction than the VB group (2.54±1.79 vs.3.19±2.14 mm,P=0.03),while there were no significant differences in setup errors in the x-or z-direction between the two groups(1.80± 1.48 vs. 1.90± 1.41 mm, P=0.46;2.14± 1.75 vs. 2.25± 1.75 mm,P=0.35). There were no significant differences in rotational setup errors in the Rx-,Ry-,or Rz-direction between the two groups(1.15°±0.76°vs. 1.15°±0.85°, P=0.50;0.71°±0.60°vs. 0.72°±0.43°, P=0.45;0.62°±0.54° vs. 0.46°±0.30°,P=0.06). The PTV margins in the x?,y?,and z?directions were expanded by 5.56, 8.57, and 7.02 mm, respectively, in the PF group, and by 5.62, 9.27, and 7.23 mm,respectively,in the VB group. The proportion of patients with 3D displacement vectors larger than 5 mm was 40% in the PF group and 45% in the VB group.Conclusions For patients undergoing radiotherapy for lung cancer,personalized polyurethane foam with wing boards can,to a certain extent,reduce the setup error in the superior-inferior direction and PTV margin expansion.[Key words] Lung neoplasms/radiotherapy; Polyurethane foam; Vacuum bag; Setup errors;Margin

Objective To investigate the relationship between single nucleotide polymorphisms of interleukin 23 receptor (IL-23R) gene and Keshan disease (KD) in Northwest Chinese Han population.Methods A total of 285 Chinese Han subjects from Huangling,Shaanxi,including 79 KD patients (case group) and 206 control subjects (control group) were involved in this study.Genomic DNA was extracted from peripheral venous blood.The polymorphism of genetic variation was genotyped by matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF).All sample groups were tested for Hardy-Weinberg equilibrium using goodness-of-fit x2 test.Differences in genotype distribution between two groups were compared by x2 test.Logistic regression analysis was applied to detect association using age as a confounding factor.Results The gene frequency distribution of IL-23R gene rs10889677 in case group and control group conformed to the Hardy-Weinberg equilibrium (x2 =0.254,P ＞ 0.05).Correlation analysis results:the difference of genotype frequency of IL-23R gene rs10889677 in case group (CC,CA,AA were 6.3％,36.7％,57.0％,respectively) and control group (CC,CA,AA were 5.3％,43.2％,51.5％,respectively) was not statistically significant (x2 =1.008,P ＞ 0.05).After age adjustment,there was no significant difference in genotype frequency of IL-23R gene rs10889677 (x2sdj =0.669,P ＞ 0.05) between two groups.Conclusion There is no correlation between IL-23R gene rs10889677 and KD in Northwest Chinese Han population.

Objective:To explore the distribution features of resident CD8 + T cells infiltration in human esophageal cancer tissues and its clinical significance. Methods:Data from the Cancer Genome Atlas database were retrieved, the correlation between CD103 + CD8 + T cells and infiltration degree of conventional type 1 dendritic cell (cDC1), conventional type 2 dendritic cell (cDC2), type 3 dendritic cell(DC3) was investigated. From January 2006 to December 2008, 78 esophageal cancer tissues and 75 adjacent normal tissues from 78 esophageal cancer patients were collected by Shanghai Outdo Biotechnology Co., Ltd, the clinical data of patients was followed up by telephone until July 2015. The distribution of CD8 + T cells and CD103 + CD8 + T cells in cancer tissues and adjacent normal tissues was detected by multi-color labeling techniques and multispectral tissue imaging. The differences of the number and the ratio of CD8 + T cells and CD103 + CD8 + T cells in cancer tissues and adjacent normal tissues were compared. The Kaplan-Meier survival curves of patients with tissue infiltration of CD8 + T cells and CD103 + CD8 + T cells at different levels were drawn through the R language " survminer" package, and the best cut-off value was obtained. TNM stage, pathological stage and other clinical parameters of patients with high and low infiltration of CD8 + T cells, CD103 + CD8 + T cells were compared. Wilcoxon rank sum test, chi-square test, log-rank test and Cox proportional risk regression model statistical analysis were used to evaluate the prognostic value of the above indicators. Spearman correlation analysis was used for correlation analysis. Results:In the cancer tissues of patients with esophageal cancer, the infiltration degree of CD103 + CD8 + T cells was positively correlated with the infiltration degree of cDC1 cells, cDC2 cells and DC3 cells ( r=0.67, 0.53 and 0.47, all P<0.001). The percentage of CD8 + T cells in all cells in the whole tissue core of tumor tissues (63.09% (42.14%, 76.21%)) was higher than that of adjacent normal tissues (2.56% (1.68%, 5.38%)), and the difference was statistically significant ( U=41.00, P<0.001). The proportion of CD103 + CD8 + T cells in all cells in the whole tissue core of tumor tissues (7.92% (1.60%, 20.61%)) was higher than that of adjacent normal tissues (0.04% (0.01%, 0.10%)), and the difference was statistically significant ( U=857.50, P<0.001). The percentage of high CD8 + T cells infiltration in esophageal cancer tissues of patients with pathological stage Ⅰ+ Ⅱ was lower than that of patients with stage Ⅲ+ Ⅳ (57.9%, 33/57 vs. 85.7%, 18/21); the percentage of high CD103 + CD8 + T cells in CD8 + T cells in esophageal cancer tissues of patients with TNM stage Ⅰ+ Ⅱ was lower than that of patients with stage Ⅲ+ Ⅳ (21.6%, 8/37 vs. 48.8%, 20/41), and the differences were both statistically significant ( χ2=5.25 and 6.23, P=0.022 and 0.013). The results of Kaplan-Meier survival analysis and univariate Cox proportional risk regression model showed that the overall survival (OS) of patients with high CD8 + T cell infiltration was longer than that of patients with low CD8 + T cell infiltration ( HR=0.57, 95% confidence interval (95% CI) 0.34 to 0.96, P=0.034). There was no significant difference in OS between patients with high CD103 + CD8 + T cell infiltration and patients with low CD103 + CD8 + T cell infiltration ( HR=0.66, 95% CI 0.40 to 1.08, P>0.05). Conclusion:The high infiltration of CD103 + CD8 + T cells in esophageal cancer tissues are expected to be used as a prognostic predictor for patients with esophageal cancer, which is an important component of anti-tumor immune response in tumor microenvironment of esophageal cancer.

[Abstract] Objective: To investigate the expression of chemokine-like factor-like MARVEL transmembrane domain-containing family member 6 (CMTM6) in breast cancer tissues and its correlation with clinicopathological features and prognosis of patients. Methods:Atotal of 136 breast cancer tissue chips (purchased from Superchip Company), including 42 pairs of matched cancer and paracancerous tissues, were used for this study. The expression level of CMTM6 in cancer and paracancerous tissues was detected by immunohistochemistry. The comparison of CMTM6 expression between breast cancer and paracancerous tissues was conducted by paired χ2 test. The relationship between CMTM6 expression in breast cancer tissues and the clinicopathological characteristics of patients was analyzed by χ2 test. Kaplan-Meier and Log rank test analyses were used to analyze the relationship between CMTM6 expression and the survival of patients, and Cox model was used to evaluate the effect of different indicators on the prognosis of patients. Results: The expression of CMTM6 in breast cancer tissues was significantly higher than that in paracancerous tissues (P<0.01). The expression of CMTM6 was correlated with pathological type of breast cancer and HER2 positivity (P<0.05). The survival time of patients in CMTM6 high expression group was significantly shorter than that of patients in CMTM6 low expression group (P<0.05). Pathological type (HR=10.374, 95%CI: 3.529-30.497, P<0.01), TNM stage (HR=4.599, 95%CI: 1.784-11.856, P<0.01), triple-negative breast cancer (HR=3.370, 95%CI: 1.055-10.761, P<0.05) and high expression of CMTM6 (HR=0.195, 95%CI: 0.073-0.518, P<0.01) were independent risk factors for prognosis of breast cancer patients. Conclusion: CMTM6 is highly expressed in breast cancer tissues, which can be used as a risk factor for prognosis evaluation of breast cancer patients.
