Objective:To analyze the detection of colorectal advanced neoplasms in the population who underwent colonoscopy screening in Henan Province as part of the Urban China Cancer Screening Program and its influencing factors.Methods:A cross-sectional study design was employed. Based on the Cancer Screening Program conducted in Henan Province, the study enrolled 7 454 urban residents who manifested no symptoms and were recruited from eight cities in the province, including Zhengzhou, Zhumadian, Anyang, Luoyang, Nanyang, Jiaozuo, Xinxiang, and Puyang from October 2013 to October 2019, and participated in colonoscopy screening. The χ 2 test was used to compare the detection rates of colorectal advanced neoplasms among participants with different characteristics, and a multivariate logistic stepwise regression model was used to analyze the factors affecting the detection rates. Results:A total of 7 454 subjects underwent colonoscopy screening, and 112 cases of colorectal advanced neoplasms were detected. Multivariate logistic regression analysis suggested that older age, smoking, higher meat intake, history of diabetes, and family history of colorectal cancer in a first-degree relative were risk factors for colorectal advanced neoplasms. The detection rate was significantly higher in people aged 60-74 years compared with those aged 40-49 years, with an odds ratio ( OR) of 2.04 (95% CI: 1.23-3.38).The rates were higher in people who smoked than those who did not smoke, with an OR of 2.21 (95% CI: 1.48-3.31), and in people who consumed more meat than those who consumed less, with an OR of 1.53 (95% CI: 1.04-2.26). Those with diabetes had a higher detection rate compared with those without, with an OR of 1.69 (95% CI: 1.07-2.69), and those with a first-degree family history of colorectal cancer had a higher detection rate than those without, with an OR of 1.64 (95% CI: 1.09-2.46). Conclusion:The detection rate of colorectal advanced neoplasms through colonoscopy screening in Henan Province covered by the Urban China Cancer Screening Program is 1.50%. Older age, smoking, higher meat intake, history of diabetes, and family history of colorectal cancer in a first-degree relative are identified as risk factors for colorectal advanced neoplasms.

Objective:To analyze the 5-year relative survival rate of cancer in Henan province based on cancer registration data.Methods:Cancer survival data were extracted from the cancer registration database of Henan province with the diagnosis date between January 1, 2010 and December 31, 2019 were included. The closing date of follow-up was set as December 31, 2019. The 5-year relative survival rate of cancer was calculated using the period survival analysis method and the Ederer II method in the R package "periodR", and the interest period was between 2015 and 2019.Results:During the period of 2015-2019, the overall 5-year relative survival rate of cancer patients in Henan province was 43.6%, and after age-standardization, it was 40.2%. The overall 5-year relative survival rate showed the characteristics of higher survival rate in females than males (45.9% vs 34.7%, Z=39.60, P＜0.001) and higher survival rate in urban areas than rural areas (44.9% vs 39.1%, Z=12.97, P＜0.001). The 5-year relative survival rate for cancer patients among children aged 0-14 was 60.2%, and for adults aged 15 and above, it was 43.5%, which was standardized to 40.2% after age adjustment. There are two types of cancers with a standardized 5-year relative survival rate exceeding 70% (thyroid cancer at 82.2% and breast cancer at 71.6%), and four cancers with a rate below 30% (pancreatic cancer at 18.2%, liver cancer at 19.6%, lung cancer at 24.0%, and gallbladder cancer at 26.6%). Conclusion:The cancer 5-year survival rate in Henan Province is lower than that of the national average, indicating the need for continued enhancement of cancer prevention and control measures.

Objective:To explore the value of contrast enhancement T1 fluid-attenuated inversion recovery sequence (CE-T1FLAIR) based on modulated flip angle technique in refocused imaging with extended echo train (MATRIX) in detecting metastases.Methods:One hundred and seventy-six patients with pathologically diagnosed malignant tumors and brain metastases accepted enhanced 3.0T MRI scan in Department of Medical Imaging, He'nan Provincial Cancer Hospital from October 2023 to February 2024 were enrolled. Lianying's intelligent brain metastasis AI-assisted detection system and sequences of MATRIX CE-T1FLAIR, 3D GRE_fsp CE-T1FLAIR and FSE CE-T1FLAIR were used to detect the brain metastasis lesions, respectively. Length of the lesions was measured according to Lianying's intelligent brain metastasis AI-assisted detection system, and all lesions were divided into 3 categories: <3 mm, 3-10 mm, and >10 mm. Differences in detection rate in brain metastases of different lengths and locations among the 3 sequences were compared.Results:Detection rates of MATRIX CE-T1FLAIR, 3D GRE_fsp CE-T1FLAIR, and FSE CE-T1FLAIR in brain metastases were 99.67%, 90.52%, and 71.02%, which were decreased successively, with significant differences ( P<0.05). Detection rates of MATRIX CE-T1FLAIR, 3D GRE_fsp CE-T1FLAIR and FSE CE-T1FLAIR in brain metastases with length<3 mm (99.24%, 79.95% and 46.45%) or length of 3-10 mm (100%, 98.19% and 87.53%) were decreased successively, with significant differences ( P<0.05). Detection rates of MATRIX CE-T1FLAIR (100%, 80.56% and 64.24%), 3D GRE_fsp CE-T1FLAIR (100%, 97.25% and 76.11%), and FSE CE-T1FLAIR (100%, 91.18% and 70.59%) in metastases at the superficial area of the brain convexity, gray-white matter junction area, and cerebellum were decreased successively, with significant differences ( P<0.05). Detection rates of FSE CE-T1FLAIR in brain metastases in the basal ganglia and brainstem (69.33% and 50%) were significantly lower than those of MATRIX CE-T1FLAIR and 3D GRE_fsp CE-T1FLAIR (97.33% and 92.86%; 88% and 78.57%, P<0.05). Conclusion:MATRIX CE-T1FLAIR sequence is better than 3D GRE_fsp CE-T1FLAIR and FSE CE-T1FLAIR sequences in detecting brain metastases, especially for metastases with length<10 mm and metastases located at the superficial area of the brain convexity, gray-white matter junction area and cerebellum.

Objective: To understand the health literacy and relevant factors of cancer prevention consciousness in Chinese urban residents from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of demographic characteristics and cancer prevention consciousness focusing on nine common risk factors, including smoking, alcohol, fiber food, food in hot temperature or pickled food, chewing betel nut, helicobacter pylori, moldy food, hepatitis B infection, estrogen, and exercise. The logistic regression model was adopted to identify the influencing factors. Results: The overall health literacy of the cancer prevention consciousness was 77.4% (24 980 participants), with 77.4% (12 018 participants), 79.9% (6 406 participants), 77.2% (1 766 participants) and 74.5% (4 709 participants) in each group (P<0.001). The correct response rates for nine risk factors ranged from 55.2% to 93.0%. The multivariate logistic regression analysis showed that compared with community residents, people with primary school level education or below, and the number of people living together in the family <3, the cancer risk assessment/screening intervention population, cancer patients, those with junior high school level educationor above and the number of people living in the family ≥3 had better health literacy of the cancer prevention consciousness (all P values <0.05). Compared with females, 39 years old and below, government-affiliated institutions or civil servants, from the eastern region, males, older than 40 years, company or enterprise employees, and from the middle or western region had worse health literacy of the cancer prevention consciousness (all P values <0.05). Conclusion The health literacy of the cancer prevention consciousness in Chinese urban residents should be improved. The cancer screening intervention, gender, age, education, occupation, the number of people co-living in the family, and residential region were associated with the health literacy of the cancer prevention consciousness.

Objective To investigate whether elevated levels of C?reactive protein ( CRP ) and neutrophil (NE) in the blood is associated with an increased risk of lung cancer incidence. Methods From 2006 to 2007, all employees and retirees from Kailuan (Group) Limited liability Corporation were included in this Kailuan Cohort study. The last follow?up date was December 2015. Data on new cases of lung cancer were collected, and multivariable Cox proportional hazards regression models were used to the relationship between baseline CRP and NE at baseline and risk of lung cancer. Results A total of 92 735 participants were enrolled in this study. During the follow?up, 850 new cases of lung cancer were identified. All subjects were divided into four groups according to the combination level of CRP and NE at baseline: CRP≤3 mg／L and NE≤4×109／L(Group A), CRP≤3 mg／L and NE＞4×109／L( Group B), CRP＞3 mg／L and NE≤4× 109／L(Group C), CRP＞3 mg／L and NE＞4×109／L(Group D).

Objective: To determine whether the anti-hepatic fibrosis effect of Fuzheng-Huayu formula is related to suppress autophagy in mice. Methods: C57 mice were randomly divided into normal group (N group) and model group. The model group was induced by intraperitoneal injection of carbon tetrachloride to induce liver fibrosis in mice, and the normal group was injected with equal volume of olive oil. After 1 week, the model group was randomly divided into model (M) group, rapamycin (Rapa) group, rapamycin plus chloroquine (Rapa+CQ) group, rapamycin plus salvianolic acid B (Rapa+Sal B) group, rapamycin plus Fuzheng -Huayu formula (Rapa+FZ) group. Each drug group was administered corresponding drugs by gavage on a daily basis, and N group and M group were given the equal amount of drinking water by gavage. After 5 weeks, the mice were sacrificed, and HE and Sirius red staining were used to observe the inflammation and collagen deposition on liver tissue in each group. The hydroxyproline content was determined by alkaline hydrolysis method. Western blotting was used to detect changes in the expression of autophagy in liver tissue and microtubule-associated protein 1 light chain 3II/I (LC3II/I), p62, α-smooth muscle actin (ɑ-SMA) and type I collagen expression. Immunofluorescence staining was used to observe the immunofluorescence localization of ɑ-SMA and LC3B in liver tissues of each group. ). A t-test was used to compare the two independent samples. LSD or Dunnett’s T3 test were used to compare the mean of multiple samples. Results: There was no significant difference in N and M groups in terms of body weight. The body weight of the mice in each drug group decreased significantly (F = 14.041, P < 0.001). The liver/spleen /body weight ratios of each drug group and M group were significantly higher than the N group (F = 26.992, 6.589, P < 0.001). The expression of p62 protein in the liver tissue of mice in each drug group was lower than M group, and the difference between Rapa group and Rapa+Sal B group (F = 3.085, P = 0.039, 0.003) was statistically significant, while that of Rapa + Sal B group was lower. Compared with group M, the expression of LC3B II in Rapa group was significantly higher (F = 7.514, P = 0.01). Immunofluorescence staining showed that LC3B and α-SMA CO-stained cells were absent in the liver of mice in N group, and co-stained cells were found in the liver of mice in M group. The co-stained cells in the liver of mice in each drug group were significantly higher than M group, and the co-stained cells in Rapa+FZ group were fewer. Compared with the N group, the collagen deposition of M group and each drug group was significantly increased; the collagen deposition of each drug group was lower than that of the M group. There was no statistically significant difference between each drug group. Compared with N group (77.75 + 48.79), hydroxyproline in liver tissue of mice in M group was significantly increased (293.48 + 84.43) (F = 3.015, P = 0.005), and the content of hydroxyproline in liver tissue of mice in each drug group was lower than M group, but the difference was not statistically significant (F = 0.750, P = 0.573). Compared with the N group, the expressions of α-SMA and type I collagen in the M group were significantly increased (F = 27.718, 18.893, P < 0.01). The expression of α-SMA in Rapa group and Rapa+Sal B group was similar to M group, while Rapa + CQ group and Rapa + FZ group were significantly lower than Rapa group and M group (P < 0.01). The expression of type I collagen in Rapa + CQ group was significantly higher than Rapa group (P = 0.017), while the expression of type I collagen in Rapa + FZ group was significantly lower than M group (P = 0.013). Conclusion Autophagy of hepatic stellate cells was observed in carbon tetrachloride-induced liver fibrosis model. Rapamycin can promote autophagy in hepatocytes and hepatic stellate cells. Fuzheng-Huayu formula and Salvianolic Acid B might antagonize the effect of rapamycin on autophagy.
