Objective To analyze the survival status of inpatients with cervical cancer registered in Nantong admitted in Nantong Cancer Hospital from 2002 to 2017. Methods Inpatients with cervical cancer in Nantong Cancer Hospital were followed up from 2017 until December 31, 2020 using active and passive methods to determine their survival outcome. The rate of follow-up loss was statistically analyzed by Chi-square test, the observed survival rate for each year was calculated using the life table, the survival curve was drawn with R language, and the survival rates of patients in different age groups and from different regions were compared with log-rank test (Mantel-Cox). Results A total of 5645 cervical cancer cases were registered. Among them, the survival outcome was recorded for 5512 cases. The success rate of follow-up was 97.64%, and the loss of follow-up rate was 2.36%. The average age of onset was 56.67±12.78 years. The median survival time was 6.54 years, and the 1-, 3-, 5-, and 10-year observed survival rates were 91.50%, 76.95%, 60.99%, and 28.51%, respectively. Among the age groups, significant differences in survival rate were observed between the 15- and 60-year-old groups (χ2=7.469, P=0.006) and between the 15- and 80-year-old groups (χ2=36.317, P < 0.001). No significant difference in survival rate was found between patients from Haimen and Qidong (χ2=2.779, P=0.095) and between patients from Qidong and Tongzhou (χ2=0.515, P=0.473). Significant difference in survival rate was observed among other regions (P < 0.05). Conclusion In this study group, the survival rates of hospital-based patients with cervical cancer significantly differ among the age groups and regions of origin and significantly decreased with age. The high follow-up rate fully reflects the comprehensive effect of the treatment in Nantong Cancer Hospital for registered patients with cervical cancer in Nantong.

Efficacy and Prognostic Factors of Nonmyeloablative Allogeneic Hematopoietic Stem Cell Transplantation for Patients with Acute Myeloid Leukemia / 中国实验血液学杂志

OBJECTIVE@#To retrospectively analyze the efficacy and complications of our institution's modified nonmyeloablative allogeneic hematopoietic stem cell transplantation (NST) in treating intermediate-risk acute myeloid leukemia (AML) - first complete remission (CR1) and prognostic factors.@*METHODS@#Clinical data of 50 intermediate-risk AML-CR1 patients who underwent matched related NST at the Fifth Medical Center of Chinese People's Liberation Army General Hospital from August 2004 to April 2021 were collected, the hematopoietic recovery, donor engraftment and complications were observed, and overall survival (OS) rate, leukemia-free survival (LFS) rate, treatment-related mortality (TRM), and cumulative relapse rate were calculated. Statistical analysis of factors affecting prognosis was also preformed.@*RESULTS@#The median times for neutrophil and platelet recovery after transplantation were 10 (6-16) and 13 (6-33) days, respectively. One month after transplantation, 22 patients (44%) achieved full donor chimerism (FDC), and 22 patients (44%) achieved mixed chimerism (MC), among whom 18 cases gradually transited to FDC during 1-11 months, 4 cases maintained MC status. The overall incidence of acute graft-versus-host disease (aGVHD) was 36%, with a rate of 18% for grade II-IV aGVHD and a median onset time of 45 (20-70) days after transplantation. The overall incidence of chronic GVHD (cGVHD) was 34%, with 20% and 14% of patients having limited or extensive cGVHD, respectively. The incidence rates of infections, interstitial pneumonia, and hemorrhagic cystitis were 30%, 10%, and 16%, respectively. The 5-year OS rate, LFS rate, TRM, and cumulative relapse rate were 68%, 64%, 16%, and 20%, respectively. The increase of the number of CD34+ cells infused had shortened the recovery time for neutrophils and platelets (r =0.563, r =0.350). The number of CD34+ cells infused significantly influenced the occurrence of extensive cGVHD (OR =1.36, 95%CI : 1.06-1.84, P =0.024).@*CONCLUSION@#Modified NST is effective in treating intermediate-risk AML-CR1 patients, however, further expansion of sample size is needed to study prognostic factors.

Functional characterization and enzymatic properties of flavonoid glycosyltransferase gene CtUGT49 in Carthamus tinctorius / 中国中药杂志

Carthami Flos, as a traditional blood-activating and stasis-resolving drug, possesses anti-tumor, anti-inflammatory, and immunomodulatory pharmacological activities. Flavonoid glycosides are the main bioactive components in Carthamus tinctorius. Glycosyltransferase deserves to be studied in depth as a downstream modification enzyme in the biosynthesis of active glycoside compounds. This study reported a flavonoid glycosyltransferase CtUGT49 from C. tinctorius based on the transcriptome data, followed by bioinformatic analysis and the investigation of enzymatic properties. The open reading frame(ORF) of the gene was 1 416 bp, encoding 471 amino acid residues with the molecular weight of about 52 kDa. Phylogenetic analysis showed that CtUGT49 belonged to the UGT73 family. According to in vitro enzymatic results, CtUGT49 could catalyze naringenin chalcone to the prunin and choerospondin, and catalyze phloretin to phlorizin and trilobatin, exhibiting good substrate versatility. After the recombinant protein CtUGT49 was obtained by hetero-logous expression and purification, the enzymatic properties of CtUGT49 catalyzing the formation of prunin from naringenin chalcone were investigated. The results showed that the optimal pH value for CtUGT49 catalysis was 7.0, the optimal temperature was 37 ℃, and the highest substrate conversion rate was achieved after 8 h of reaction. The results of enzymatic kinetic parameters showed that the K_m value was 209.90 μmol·L~(-1) and k_(cat) was 48.36 s~(-1) calculated with the method of Michaelis-Menten plot. The discovery of the novel glycosyltransferase CtUGT49 is important for enriching the library of glycosylation tool enzymes and provides a basis for analyzing the glycosylation process of flavonoid glycosides in C. tinctorius.

Mismatched donor cell infusion-related syndrome following microtransplant in patients with acute myeloid leukemia / 中华医学杂志(英文版)

BACKGROUND@#Immunotherapies such as adoptive immune cell infusion and immune-modulating agents are widely used for cancer treatment, and the concomitant symptoms, including cytokine release syndrome (CRS) or immune-related adverse events (irAEs), are frequently reported. However, clinical manifestations induced by mismatched donor granulocyte colony-stimulating factor mobilized peripheral blood mononuclear cell (GPBMC) infusion in patients receiving microtransplant (MST) have not yet been well depicted.@*METHODS@#We analyzed 88 cycles of mismatched GPBMC infusion in patients with acute myeloid leukemia receiving MST and 54 cycles of chemotherapy without GPBMC infusion as a comparison. Clinical symptoms and their correlation with clinical features, laboratory findings, and clinical response were explored.@*RESULTS@#Fever (58.0% [51/88]) and chills (43.2% [38/88]) were the significant early-onset symptoms after GPBMC infusion. Patients possessing less human leukocyte antigen-matching loci with the donor or those with unrelated donors experienced more chills (3 [2-5] loci vs. 5 [3-5] loci, P  = 0.043 and 66.7% [12/18] vs. 37.1% [26/70], P  = 0.024). On the other hand, those with decreased CD4 + /CD8 + T-cell ratio developed more fever (0.8 [0.7-1.2] vs. 1.4 [1.1-2.2], P  = 0.007). Multivariable analysis demonstrated that younger patients experienced more fever (odds ratio [OR] = 0.963, 95% confidence interval [CI]: 0.932-0.995, P  = 0.022), while patients with younger donors experienced more chills (OR = 0.915, 95% CI: 0.859-0.975, P  = 0.006). Elevated ultra-sensitive C-reactive protein levels in the absence of cytokine storm were observed following GPBMC infusion, which indicated mild and transient inflammatory response. Although no predictive value of infusion-related syndrome to leukemia burden change was found, the proportion of host pre-treatment activated T cells was positively correlated with leukemia control.@*CONCLUSIONS@#Mismatched GPBMC infusion in MST induced unique infusion-related symptoms and laboratory changes, which were associated with donor- or recipient-derived risk factors, with less safety and tolerance concerns than reported CRS or irAEs.

Disease burden of chronic kidney disease attributable to metabolic factors in Jiangsu Province in 1990 -2019 / 公共卫生与预防医学

Objective To analyze the burden of chronic kidney disease (CKD) attributable to metabolic factors in Jiangsu Province from 1990 to 2019, and to provide evidence for the formation and implementation of intervention policies. Methods Using data from Jiangsu Province from the 2019 Global Burden of Disease Study (GBD 2019), mortality and disability-adjusted life-years (DALYs) were selected as indicators for analysis and standardized with the age structure of the world standard population. The effects of three metabolic factors including high systolic blood pressure (SBP), high fasting glycaemic index (FPG) and high body mass index (BMI) on the disease burden of CKD were analyzed, and the attributable disease burden by gender and age was compared. Results The rank of the three attributable risk factors was high SBP, high FPG, and high BMI. Standardized mortality rates attributable to high SBP, high FPG, and high BMI all showed an overall upward trend from 1990 to 2019, with annual average percent changes (AAPCs) of 0.3%, 0.0%, and 2.8%, respectively. Age-standardized DALYs attributed to high SBP and high BMI showed increasing trends, with the AAPCs of 0.5% and 3.1% (both P＜0.05), respectively. There was no statistical significance of high FPG (P > 0.05). Mortality and disease burden attributed to high SBP both showed upward trends with increasing age. Age-standardized mortality and age-standardized DALYs attributed to high FPG peaked at 45-49 and 50-54 age-group, respectively. Both age-standardized mortality and age-standardized DALYs attributed to high BMI peaked at ages 60-64 age-group. Conclusion The trends of mortality and DALYs attributed to the three risk factors can reflect the changes of population structure and lifestyle in Jiangsu Province in the past 30 years to a certain extent. Early screening of population at high risk of CKD and targeted provision of health policies can reduce the mortality and disease burden of CKD.

Changes in corneal biomechanics after small incision lenticule extraction and femtosecond laser-assisted laser in situ keratomileusis evaluated by corneal visualization Scheimpflug technology / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To evaluate the changes in corneal biomechanics of patients with moderate refractive error after receiving small-incision lenticule extraction(SMILE)and femtosecond laser-assisted laser in situ keratomileusis(FS-LASIK)using the corneal visualization Scheimpflug technology(Corvis ST).METHODS:Prospective cohort study. A total of 65 moderate myopia patients(65 eyes)who were scheduled to undergo refractive surgery at the Ophthalmic Refractive Surgery Center of the Ningxia Eye Hospital from November 2020 to November 2021 were included in the study, and there were 30 eyes in the SMILE group and 35 eyes in the FS-LASIK group. The changes in corneal biomechanical parameters, including integrated radius(IR), inverse concave radius(ICR), deformation amplitude ratio 2mm(DAR2), stiffness parameter at first applanation(SP-A1), ambrosio relational thickness(ARTh)and the central curvature radius at highest concavity(HC-Radius)were observed by Corvis ST between both groups preoperatively and 1 and 3mo postoperatively.RESULTS: There were no statistical significance in biomechanical parameters between two groups of patients 1 and 3mo postoperatively(P&#x0026;#x003E;0.05). IR, ICR and DAR2 of each groups of patients 1 and 3mo postoperatively were significantly increased than those preoperatively, and SP-A1, ARTh and HC-Radius were significantly decreased than those preoperatively(all P&#x0026;#x003C;0.05). The biomechanical parameters at 1mo and 3mo postoperatively showed no statistical significance(P&#x0026;#x003E;0.05). In addition, a positive correlation was found between central corneal thickness(CCT)and ARTh and SP-A1 of the two groups of patients at 3mo postoperatively(FS-LASIK group: r=0.727, 0.819, SMLIE group: r=0.683, 0.434, all P&#x0026;#x003C;0.05), while a negative correlation was found between CCT and IR and ICR at 3mo postoperatively.(FS-LASIK group: r=-0.697, -0.622, SMLIE group: r=-0.447, -0.491, all P&#x0026;#x003C;0.05).CONCLUSION:For patients with moderate myopia, both SMILE and FS-LASIK can reduce corneal biomechanical stability. Both surgeries showed no significant differences in the effect on biomechanical, and the biomechanical has been stabilized at 1mo postoperatively. A correlation was found between postoperative CCT and ARTh, SP-A1, IR and ICR.

Porcine Circular RNA Insulin-like Growth Factor 1 Receptor Promotes Adipocyte Differentiation / 中国生物化学与分子生物学报

Circular RNA (circRNA), as a competitive endogenous RNA (ceRNA), plays an importantrole in the regulation of cell differentiation. The purpose of this study was to identify and analyze porcinecircular RNA insulin-like growth factor 1 receptor (circIGF1R), explore its expression patterns, construct a ceRNA regulatory network related to circIGF1R, and explore the regulation of its ectopicexpression on adipogenic differentiation of mouse mesenchymal stem cells (C3H10T1 / 2) effect. Forwardand reverse PCR, Sanger sequencing, RNase R enzyme digestion tests, and qRT-PCR were used toverify that circIGF1R is a circRNA formed by the second exon of insulin-like growth factor 1 receptor(IGF1R). It was expressed in all tissues of pigs, and its expression level increased with age in adiposetissues. miRDB, TargetScan and miRWalk online software were used to predict circIGF1R target genes. RNAhybrid software was used for binding site prediction. DAVID bioinformatics functional analysissoftware was used to perform GO and KEGG enrichment analysis on candidate target genes. Cytoscapesoftware was used to construct the ceRNA network diagram. Based on the gene expression correlation andpredicted target relationship, the GO and KEGG enrichment analysis was drawn and the ceRNA networkwas constructed; the dual luciferase reporter gene test was used, and we found that circIGF1R andFABP4 can bind to ssc (Sus scrofa chromosome) -miR-133a-5p. The circIGF1R overexpression vectorwas successfully constructed and expressed in C3H10T1/ 2 cells. It was found that after overexpression ofcircIGF1R, the expression of key adipogenic regulatory factors CEBPa, CEBPß, FABP4 and PPAR? increased significantly(P<0. 01), and the number of lipid droplets increased significantly. The results ofthis study show that circIGF1R exists in pig adipose tissues, and may positively regulate the adipogenicdifferentiation of C3H10T1/ 2 cells through the ceRNA mechanism, which lays a theoretical foundation forfurther research on circIGF1R regulating the adipogenic differentiation of pig precursor intramuscularadipocytes.

Effects of Bupleurum chinense on the diversity of intestinal flora in depressed mice / 中国中药杂志

Bupleuri Radix, serving as the sovereign medicinal in many antidepressant compound preparations, has been proved effective in treating depression in mice, but its effect on the intestinal flora remains unclear. The present study aimed to investigate the effects of Bupleurum chinense(one of the original materials of Bupleuri Radix) on the behaviors and the diversity of intestinal flora of depressed mice. A depression mouse model was induced by repeated social defeat stress. Specifically, C57 BL/6 J male mice were exposed to the attack from the CD-1 mice. Then, C57 BL/6 J male mice were divided into a depression group and a B. chinense group, with normal saline and B. chinense administered(ig) respectively. Sucrose preference test and tail suspension test were conducted during and after the experiment respectively, to analyze the effects of B. chinense on the behaviors of the depressed mice. The feces were collected after the experiment. The V3-V4 16 S rDNA regions of intestinal flora of mice in each group were sequenced by Ion S5 TMXL for the analysis of the number of operational taxonomic units(OTUs), richness, alpha and beta diversity indexes, and differential phyla and genera. The results indicated that B. chinense could decrease depressive-like behaviors of mice, increase sucrose preference, and shorten the time of immobility in tail suspension test. After B. chinense intervention, the relative abundance of Firmicutes was significantly decreased, while that of Bacteroidetes was increased at the phylum level. At the genus level, the relative abundance of Lactobacillus and Lachnoclostridium decreased(P<0.05), while that of Bacteroides, Alistopes, etc. was elevated(P<0.05). The findings demonstrate that B. chinense can regulate the intestinal flora and improve the depressive-like behaviors of mice with depression.

FNDC5 Regulates the Adipogenic Differentiation of C3H10T1/2 Cells by Inhibiting the Phosphorylation of ERK1/2 / 中国生物化学与分子生物学报

The aim of this study was to explore the regulatory mechanism of Type Ⅲ domain-containing protein5 (FNDC5) on adipogenic differentiation in C3H10T1/2 cells. qRT-PCR and Western blot were used to detect the expression of FNDC5 during adipogenic differentiation of C3H10T1/2 cells. The lentivirus-coated overexpression and interference vector of FNDC5 were constructed and transfected into C3H10T1/2 cells. qRT-PCR was used to detect the expression of the key genes of adipogenic differentiation. Oil red O staining was used to detect the formation of lipid droplets; Western blot was used to detect the content of ERK1/2 and ERK1/2 phosphorylated protein (P-ERK1/2). After 8 days of adipogenic differentiation of C3H10T1/2 cells, the expression of Fndc5 increased significantly. After overexpression of FNDC5 in C3H10T1/2 cells, the expression of key genes for adipogenic differentiation, including peroxisome proliferator-activated receptor-酌 (PPAR酌), CCAAT enhancer binding protein beta (C/EBP茁), fatty acid binding protein 4 (FABP4) and CCAAT enhancer binding protein alpha (C/EBPα), all decreased significantly. The content of lipid droplets and P-ERK1/2 also decreased significantly. On the contrary, after interference of FNDC5 in C3H10T1/2 cells, the expression of key genes for adipogenic differentiation, including PPARγ, C/EBP茁, FABP4 and C/EBPα were significantly increased. Meanwhile, the content of lipid droplets and P-ERK1/2 also increased significantly. This study found that FNDC5 can inhibit the adipogenic differentiation of C3H10T1/2 cells by inhibiting the phosphorylation level of ERK1/2, which can provide reference data for the mechanism of FNDC5 in regulating fat deposition.

The level of health literacy of the cancer prevention and treatment of residents aged 50 to 69 years old, other occupational groups, unmarried, the central and western region residents and the group with unclear self-assessment of cancer risk was significantly lower than that of residents younger than 40 years old, personnel of public institutions/civil servants, married, the eastern region residents and the group whose self-assessment without cancer risk (P<0.05) . The level of health literacy of cancer prevention and treatment of females, people who went to high school or over, cancer risk assessment/screening population, cancer patients and occupational population was significantly higher than that of males, people who had an education level of primary school or below and community residents (P<0.05) .@*Conclusion@#The health literacy of the cancer prevention and treatment of urban residents in China was relatively high, but there was still room for improvement. Gender, age, educational level, occupation, region, marital status, self-assessment of cancer risk, and type of respondents were the key influencing factors of the health literacy of the cancer prevention and treatment. Male, 50-69 years old, lower educational level, central and western regions, unclear cancer risk self-assessment, and without specific environmental exposure to cancer prevention and treatment knowledge or related risk factors were the characteristics of the key intervention group of the health literacy of the cancer prevention and treatment.

Analysis on the consciousness of the early cancer treatment and its influencing factors among urban residents in China from 2015 to 2017 / 中华预防医学杂志

Objective@#To understand the consciousness of the cancer early treatment and its demographic and socioeconomic factors.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) 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 questionnaire collected personal information, the consciousness of the cancer early treatment and relevant factors. The Chi square test was used to compare the difference between the consciousness of the cancer early treatment and relevant factors among the four groups. The logistic regression model was used to analyze the influencing factors related to the consciousness of the cancer early treatment.@*Results@#With the assumption of being diagnosed as precancer or cancer, 89.97% of community residents, 91.84% of cancer risk assessment/screening population, 93.00% of cancer patients and 91.52% of occupational population would accept active treatments (P<0.001). If the immediate family members were diagnosed as precancer or cancer, people who would encourage their family members to receive early treatment in the four groups accounted for 91.96%, 91.94%, 92.44% and 91.55%, respectively (P<0.001). The company employees, annual household income with 40 000 yuan and more and other three groups had a relatively better consciousness of the cancer early treatment (P<0.05). Male, widowed, unemployed and from the central and western regions had a relatively worse consciousness of the cancer early treatment (P<0.05).@*Conclusion@#Residents in urban China participants had a good consciousness of the cancer early treatment. The marital status, occupation, annual household income and residential regions were major factors related to the consciousness of the cancer early treatment.

Analysis on the consciousness of the early cancer diagnosis and its related factors among urban residents in China from 2015 to 2017 / 中华预防医学杂志

Objective@#To understand the consciousness of the cancer early diagnosis among urban residents and identify the related factors 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 general demographic characteristics, the consciousness of the cancer early diagnosis (whether people would have a willingness or encourage their relatives/friends to confirm the abnormal results once which were detected from the physical examination) and other information were collected by using the self-designed questionnaire. The non-conditional logistic regression model was used to identify the relateol factors related to the consciousness of the cancer early diagnosis.@*Results@#As for residents with abnormal result from the physical examination, 89.29% (28 802) of residents would choose to seek medical treatment for further diagnosis. If their relatives/friends had abnormal results from the physical examination, 89.55% (28 886) of residents would encourage their relatives/friends to confirm the diagnosis in time. The non-conditional logistic regression model analysis showed that compared with the public institution staff/civil servants, annual household income less than 20 000 CNY, the western region and the cancer risk assessment/screening intervention population, the company staff, annual household income about 40 000 CNY and more, and the residents from the middle and eastern region had a stronger consciousness to seek further diagnosis; while the unemployed residents and community residents were less likely to seek further diagnosis (P<0.05).@*Conclusions@#From 2015 to 2017, the Chinese urban residents had a good consciousness of the cancer early diagnosis. Occupation, annual household income, residential region and population group were related to the consciousness of the cancer early diagnosis.

Analysis on the consciousness of the cancer early detection and its influencing factors among urban residents in China from 2015 to 2017 / 中华预防医学杂志

Objective@#To understand the consciousness of the cancer early detection among urban residents and identify the influencing factors 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. Self-designed questionnaires were used to collect population, socioeconomic indicators, self-cancer risk assessment, regular participation in physical examination and other information. The multivariate logistic regression model was used to identify the factors of people who had not regularly participated in the regular physical examination in the past five years.@*Results@#The self-assessment results of 32 357 residents showed that there were 27.54% (8 882) of total study population with self-reported cancer risk, 45.48% (14 671) without cancer risk and 26.98% (8 704) with unclear judgement on their own cancer risk. Among population with cancer risk, 79.84% (7 091) considered physical examination accounted. In the past five years, there were 21 105 (65.43%) residents participated in regular physical examination and 11 148 (34.56%) participated in non-scheduled one, respectively. The multivariate logistic regression analysis showed that compared with unmarried and western region residents, divorced, middle and eastern region residents had a stronger consciousness to participate in the regular physical examination (P<0.05). Compare with residents with annual household income less than 20 000 CNY in 2014, cancer risk assessment/screening intervention population, and self-assessment with cancer risk, residents with annual household income between 20 000 CNY and 59 000 CNY in 2014, occupational population, community residents, cancer patients, self-reported cancer-free risk, and self-assessment with unclear judgement of cancer risk were less likely to participate in the regular physical examination (all P values <0.05).@*Conclusion@#From 2015 to 2017, the Chinese urban residents had a acceptable consciousness of the cancer early detection. The marital status, annual household income, population group and self-assessment of cancer risk were related to the consciousness of the cancer early detection of people who had not participated in the regular physical examination in the past five years.

Study on the health literacy and related factors of the cancer prevention consciousness among urban residents in China from 2015 to 2017 / 中华预防医学杂志

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.
