Objective: To compare the application effect of the colonoscopy, fecal immunochemical test (FIT) and novel risk-adapted screening approach in colorectal cancer screening in Xuzhou population. Methods: From May 2018 to April 2019, 4 280 subjects aged 50-74 were recruited from Gulou district, Yunlong district and Quanshan district of Xuzhou. They were randomly assigned to the colonoscopy group (n=863), FIT group (n=1 723) and novel risk-adapted screening approach group (n=1 694) according to the ratio of 1∶2∶2. For the novel risk-adapted screening approach group, after the risk assessment, high-risk subjects were invited to undergo colonoscopy and low-risk subjects were invited to undergo FIT examination. All FIT positive subjects were invited to undergo colonoscopy. Colonoscopy participation rate [(the number of colonoscopies completed/the number of colonoscopies invited to participate)×100%], detection rate of colorectal lesions [(the number of diagnosed patients/the number of colonoscopies completed)×100%], colonoscopy resource load (the number of colonoscopies completed/the number of diagnosed advanced tumors) and FIT resource load in each group were calculated and compared. Results: The age of all subjects was (61±6) years old, including 1 816 males (42.43%). There was no statistically significant difference in the socio-demographic characteristics of the subjects in different screening groups. The colonoscopy participation rate was 22.60% (195/863) in the colonoscopy group, 57.04% (77/135) in the FIT group, and 33.94% (149/439) in the novel risk-adapted screening approach group, respectively. The colonoscopy participation rate was higher in the FIT group than in the colonoscopy group and the novel risk-adapted screening approach group (P<0.001). The colonoscopy participation rate of novel risk-adapted screening group was significantly higher than the colonoscopy group (P<0.001). The detection rates of advanced tumors were 6.67% (13/195), 9.09% (7/77) and 8.72% (13/149), respectively, and the difference was not statistically significant (P>0.05). The colonoscopy resource load (95%CI) was 15 (13-17) in the colonoscopy group, 11 (9-14) in the FIT group and 11 (10-13) in the novel risk-adapted screening approach group, respectively. Among them, the colonoscopy resource load of high-risk individuals in the novel risk-adapted screening approach group was 12 (9-15). FIT resource loads (95%CI) were 207 (196-218) and 88 (83-94) in the FIT group and the novel risk-adapted screening approach group. Conclusion: The combined application of risk-adapted screening approach and FIT may have a good application effect in colorectal cancer screening.

OBJECTIVE: To analyze the risk factors affecting hemorrhagic cystitis(HC) after allogeneic hematopoietic stem cell transplantation(allo-HSCT). METHODS: The clinical data of 153 patients underwent allogeneic hematopoietic stem cell transplantation in the First Affiliated Hospital of Xi'an Jiaotong University from January 2010 to December 2018 were selected and retrospectively analyzed. The incidence, median time and treatment outcome of HC should be observed. Multivariate analysis was used to observe the risk factors of HC in patients, including sex, age, diagnosis, disease status before transplantation, transplantation type, ATG and CTX in the pretreatment scheme, stem cell source, neutrophil and platelet implantation time; CMV, EBV and BKV infection, and acute graft-versus-host disease(aGVHD). RESULTS: Among 153 patients underwent allogeneic hematopoietic stem cell transplantation, 25 (16.34%) patients had HC, the median occurance time was 31 days, all patients achieved complete remission after treatment, no bladder irritation and bladder contracture were left. The results of univariate and multivariate Logistic regression analysis showed that the type of transplantation, ATG, CMV viremia before treatment, aGVHD (r=1.036, 3.234, 3.298 and 2.817, respectively) were the independent risk factors of HC. CONCLUSION The urinary BKV detections in the patients with HC are positive, mainly occured during the period from day +13 to days +56. HLA haplotype, pretreatment including ATG, and CMV viremia, and aGVHD are the independent risk factors for HC after allo-HSCT.

Objective: To investigate the correlation between skin elasticity and setup error in optical surface image-guided radiotherapy. Methods: The skin elasticity (R7) data of the head, chest and abdomen were extracted and analyzed its correlation with age by systematic literature review. Fifty-four patients diagnosed with nasopharyngeal carcinoma, breast cancer and cervical cancer were recruited in this study. Firstly, the patients were positioned based on the room laser and markers. Subsequently, the patient position was verified by the Varian On-Board Imager, and then C-Rad Catalyst was adopted to obtain surface images in two states (mask or non-mask) as reference images. In the subsequent fraction treatment, after initial positioning, the local calibration was performed by Catalyst, and setup errors in three directions were recorded. Meanwhile, the patient setup was verified by CBCT twice a week. The Pearson correlation analysis was performed to analyze the correlation between setup error and age. Results: The skin elasticity was negatively correlated with aging (P<0.01). The correlation coefficient between random error and age in head-and-neck cancer were 0.645, 0.624 and 0.866 in the AP, SI and LR directions (all P<0.05) for male patients without mask, respectively. The system error was significantly correlated with age in the LR direction (P<0.05) for male patients, and in the AP direction (P<0.05) for female patients with head-and-neck cancer without mask. The setup error had a significant correlation with skin elasticity in male patients with head-and-neck cancer, and the sequence of absolute value of correlation coefficient was LR>SI>AP. Conclusion In optical surface-guided radiotherapy of head and neck cancer, skin elasticity may be a significant index for assessing the setup errors in male patients.

Objective: To explore the effect of Huangqisan on endoplasmic reticulum stress signaling pathway in liver tissues of high-fat diet-induced obese rats and its mechanisms. Method: Male SD rats were selected and fed with high-fat diet for 7 weeks continuously to establish an obese rat model. Then, the rats were randomly divided into model group, low and high-dose Huangqisan group (1.2, 2.4 g·kg^-1), and Lipitor group (2 mg·kg^-1), and orally administered with drugs for 15 consecutive weeks. The control group and the model group were perfused with the same volume of normal saline. The body weight, epididymal fat coefficient and liver coefficient of each group were determined separately. Fasting plasma glucose (FPG), total cholesterol (TC), triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C) were determined by biochemical reagent method. The epididymal visceral adipose tissue and liver pathological changes were observed by hematoxylin and eosin (HE) staining. And the protein expression levels of sterol regulation element-binding transcription factor 1 (SREBP-1c), protein kinase R (PKR)-like endoplasmic reticulum kinase (PERK), inositol requiring enzyme 1 (IRE1α), p-inositol requiring enzyme 1 (p-IRE1α) in liver tissues were detected by Western blot methods. Result: Compared with the control group, the body weight, epididymal fat coefficient and liver coefficient of the model group were significantly increased(P<0.01), and the levels of FPG, TC, TG and LDL-C were also higher than those of the control group(P<0.05,P<0.01). The cell volume of epididymal fat and liver in the model group were enlarged, and numerous fat vesicles were observed in the cells. Meanwhile, the protein expression levels of the endoplasmic reticulum stress-related factors SREBP-1c, PERK, IRE1α/p-IRE1α were increased(P<0.05,P<0.01). Compared with the model group, high-dose and low-dose Huangqisan groups could significantly reduce the body weight, epididymal fat coefficient, liver coefficient and levels of glucose and lipid(P<0.05,P<0.01), and pathological examination showed that the lesion degrees of epididymal fat and liver tissues were alleviated obviously. In addition, Huangqisan could mostly reduce SREBP-1c, PERK, IRE1α/p-IRE1α protein expression levels to different degrees(P<0.05,P<0.01). Conclusion: Huangqisan could regulate the glucose and lipid metabolism, alleviate liver pathology and reduce body weight, and its mechanism was probably related to reduction of SREBP-1c, PERK, IRE1α/p-IRE1α proteins expression levels.

The present study analyzed the predictive value of combined analysis of collapsin response mediator protein 4 (CRMP4) methylation levels and the Cancer of the Prostate Risk Assessment (CAPRA-S) Postsurgical score of patients who required adjuvant hormone therapy (AHT) after radical prostatectomy (RP). We retrospectively analyzed 305 patients with prostate cancer (PCa) who received RP and subsequent androgen deprivation therapy (ADT). Two hundred and thirty patients with clinically high-risk PCa underwent immediate ADT, and 75 patients with intermediate risk PCa underwent deferred ADT. CRMP4 methylation levels in biopsies were determined, and CAPRA-S scores were calculated. In the deferred ADT group, the values of the hazard ratios for tumor progression and cancer-specific mortality (CSM) in patients with ≥15% CRMP4 methylation were 6.81 (95% CI: 2.34-19.80) and 12.83 (95% CI: 2.16-26.10), respectively. Receiver-operating characteristic curve analysis indicated that CRMP4 methylation levels ≥15% served as a significant prognostic marker of tumor progression and CSM. In the immediate ADT group, CAPRA-S scores ≥6 and CRMP4 methylation levels ≥15% were independent predictors of these outcomes (uni- and multi-variable Cox regression analyses). The differences in the 5-year progression-free survival between each combination were statistically significant. Combining CAPRA-S score and CRMP4 methylation levels improved the area under the curve compared with the CRMP4 or CAPRA-S model. Therefore, CRMP4 methylation levels ≥15% were significantly associated with a poor prognosis and their combination with CAPRA-S score accurately predicted tumor progression and metastasis for patients requiring AHT after RP.
