Objective:To explore the clinical features and prognosis of simultaneous double primary and single primary colorectal cancer patients.Methods:A retrospective case series study was conducted. The clinical data of 45 patients with simultaneous double primary colorectal cancer, 53 patients with single primary colon cancer and 59 patients with single primary rectal cancer in Shanxi Province Cancer Hospital from January 2015 to January 2018 were retrospectively analyzed, including gender, age, drinking history, smoking history, body mass index (BMI), carcinoembryonic antigen (CEA), carbohydrate antigen 199 (CA199), hemoglobin, albumin, TNM stage. The clinicopathological characteristics of the three groups were compared. Survival analysis was performed using the Kaplan-Meier method to compare the overall survival of the three groups.Results:The age of simultaneous double primary colorectal cancer patients was (63±11) years old, including 28 males and 17 females; the age of single primary colon cancer patients was (61±12) years old, including 30 males and 23 females; the age of single primary rectal cancer patients was (60±11) years old, including 30 males and 29 females. There was a significant difference in BMI between patients with double primary cancer and single primary colon cancer ( P = 0.041), but there were no significant differences in gender, age, drinking history, smoking history, CEA, CA199, hemoglobin, albumin and TNM stage (all P > 0.05). There were significant differences in BMI, CEA and CA199 between patients with double primary cancer and single primary rectal cancer (all P < 0.05), but there were no significant differences in gender, age, drinking history, smoking history, hemoglobin, albumin and TNM stage (all P > 0.05). The 1-, 3- and 5-year overall survival rates of the double primary cancer patients were 95.56%, 77.78% and 62.22%, the single primary colon cancer patients were 94.34%, 81.13% and 69.81%, and the single primary rectal cancer patients were 100.00%, 88.14% and 72.88%, respectively. There was no significant difference in OS among patients with double primary cancer, single primary rectal cancer and single primary rectal cancer (both P > 0.05). Conclusions:Abnormally elevated BMI may be associated with the risk of developing simultaneous double primary colorectal cancer. Detection of CEA and CA199 is helpful in monitoring rectal cancer patients for the combination of other primary tumors. The prognosis of patients with single primary colon or rectal cancer is comparable to that of patients with simultaneous double primary colorectal cancer.

Objective:To analyze the clinical curative effects of wire-to-port drainage and put-aside drainage after incision and hanging on perianal abscess.Methods:Eighty-two patients with perianal abscess admitted to Anqing Municipal Hospital between November 2019 and November 2022 were enrolled. The patients were divided into group A (41 cases, incision and hanging wire-to-port drainage) and group B (41 cases, incision and hanging put-aside drainage) by random digits table method. The clinical curative effect, operation time, wound healing time, postoperative recovery time and hospitalization time in the two groups were compared. The pain and anal function were evaluated by visual analogue score (VAS) and Wexner continence grading score (Wexner score) before surgery and 1, 7 d after surgery. The occurrence of complications within 1 month after surgery was statistically analyzed.Results:There was no significant difference in total clinical response rate between group A and group B ( P>0.05). There was no significant difference in operation time between the two groups ( P>0.05). The wound healing time, postoperative recovery time and hospitalization time in group A were significantly shorter than those in group B: (21.34 ± 2.21) d vs. (27.86 ± 2.84) d, (23.12 ± 2.42) d vs. (28.36 ± 2.91) d, (8.12 ± 0.83) d vs. (13.25 ± 1.47), P<0.05. At 1 and 7 d after surgery, the VAS and Wexner score in group A were lower than those in group B: (6.11 ± 0.62) points vs. (6.54 ± 0.67) points, (2.39 ± 0.25) points vs. (3.21 ± 0.33) points, (7.54 ± 0.77) points vs. (8.96 ± 0.91) points, (4.22 ± 0.43) points vs. (5.68 ± 0.58) points, P<0.05. There was no significant difference in total incidence of complications between the two groups within 1 month after surgery ( P>0.05). Conclusions:Compared with incision and hanging put-aside drainage, incision and hanging wire-to-port drainage can promote wound healing, shorten hospitalization time, relieve postoperative pain and improve anal function in patients with perianal abscess, with certain safety.

OBJECTIVE@#To assess the value of Improved Mayo Endoscopic Score (IMES) for evaluation of treatment efficacy for active ulcerative colitis (UC).@*METHODS@#We retrospectively analyzed the clinical and endoscopic data of 103 patients diagnosed with active UC in Beijing Tsinghua Changgung Hospital from January, 2015 to December, 2020. The severity of endoscopic lesions was determined by Mayo Endoscopic Score and the Ulcerative Colitis Endoscopic Index of Severity (UCEIS), and the area of the endoscopic lesions was evaluated based on the Montreal classification system. The IMES was established by combining the MES with the Montreal classification.@*RESULTS@#Univariate analysis suggested that young patients (<40 years old), patients with extensive disease type (E3), patients with high endoscopic scores (MES=3, UCEIS>4, and IMES>4), and patients receiving advanced drug therapy (with systemic hormones, immunosuppressants, immunomodulators, and biological agents, etc.) had lower clinical and endoscopic remission rates. COX survival analysis showed that IMES≤4 was an independent risk factor for clinical and endoscopic remission. ROC curve indicated that the predictive value of IMSE≤4 for clinical and endoscopic remission (AUC=0.7793 and 0.7095, respectively; P<0.01) was better than that of Montreal (AUC=0.7357 and 0.6847, respectively; P<0.01), MES=2 (AUC=0.6671 and 0.5929, respectively; P<0.01), and UCEIS≤4 (AUC=0.6823 and 0.6459, respectively; P<0.01); IMES=5 had a better predictive value for patients with active UC undergoing colectomy tham E3 and MES=3.@*CONCLUSION@#IMES has good value in evaluating treatment efficacy for active UC.

ObjectiveThe objective is to investigate the possibility of isocenter dual-guided resetting of surface guided radiation therapy (SGRT) combined with image guided radiation therapy (IGRT) in postoperative radiotherapy for breast cancer. To assess the setup error accuracy between the new resetting mode and the traditional resetting mode. MethodsRetrospective analysis was performed on breast cancer patients who underwent ELEKTA infinity accelerator radiotherapy in sun yat-sen university cancer center from July 13, 2021 to October 15, 2022. According to different reset methods, the patients were divided into a simulation group (41 cases) and a dual-guided group (40 cases). The simulation group was reset using a simulator, CBCT scans were performed and setup errors were recorded during the first treatment; The dual-guided group was guided by AlignRT and combined with CBCT for isocenter dual-guided resetting, and the setup error obtained by CBCT registration was recorded. The global setup errors of chest region of interest (CROI) , the local residual errors of supraclavicular region of interest (SROI) and the resetting time of the two reset methods were calculated and compared respectively. The advantages of the CBCT error distribution in the dual-guided resetting of SGRT combined with IGRT were analyzed. ResultsThe median of the global setup errors (X/cm, Y/cm, Z/cm, Rx°, Ry°, Rz°) of the simulation group and the median of the dual-guided group in the CROI were statistically significant (P<0.05) except the Rz and Ry directions. The local residual errors of the two groups of the SROI were calculated. The median of the errors of X/cm, Y/cm, Z/cm, Rx°, Ry°, Rz° were statistically significant (P<0.05) except the X and Y axis. The resetting time of the simulation group was significantly longer than that of the dual-guided group (238.64±28.56) s, t=-24.555, P=0.000, and the difference was statistically significant (P<0.05). The CBCT error distribution of the dual-guide group was analyzed, and it was found that the absolute values of translation errors of X, Y and Z axis were all within 0.4 cm, while the proportions of ≤ 0.3 cm were 95%, 93% and 93%, respectively. The proportions of rotation errors of Rx, Ry and Rz ≤ 1.5 ° were 90%, 93% and 90%, respectively. ConclusionIn postoperative radiotherapy of breast cancer, SGRT combined with IGRT for isocenter dual-guided resetting can effectively correct the rotational setup errors and residual errors, and improve the accuracy of radiotherapy with less resetting time and high feasibility, which compared with the traditional simulator resetting mode. This precise, unmarked resetting method can be widely used in clinical practice.
Résumé
OBJECTIVE@#We aimed to assess the feasibility and superiority of machine learning (ML) methods to predict the risk of Major Adverse Cardiovascular Events (MACEs) in chest pain patients with NSTE-ACS.@*METHODS@#Enrolled chest pain patients were from two centers, Beijing Anzhen Emergency Chest Pain Center Beijing Bo'ai Hospital, China Rehabilitation Research Center. Five classifiers were used to develop ML models. Accuracy, Precision, Recall, F-Measure and AUC were used to assess the model performance and prediction effect compared with HEART risk scoring system. Ultimately, ML model constructed by Naïve Bayes was employed to predict the occurrence of MACEs.@*RESULTS@#According to learning metrics, ML models constructed by different classifiers were superior over HEART (History, ECG, Age, Risk factors, & Troponin) scoring system when predicting acute myocardial infarction (AMI) and all-cause death. However, according to ROC curves and AUC, ML model constructed by different classifiers performed better than HEART scoring system only in prediction for AMI. Among the five ML algorithms, Linear support vector machine (SVC), Naïve Bayes and Logistic regression classifiers stood out with all Accuracy, Precision, Recall and F-Measure from 0.8 to 1.0 for predicting any event, AMI, revascularization and all-cause death ( vs. HEART ≤ 0.78), with AUC from 0.88 to 0.98 for predicting any event, AMI and revascularization ( vs. HEART ≤ 0.85). ML model developed by Naïve Bayes predicted that suspected acute coronary syndrome (ACS), abnormal electrocardiogram (ECG), elevated hs-cTn I, sex and smoking were risk factors of MACEs.@*CONCLUSION@#Compared with HEART risk scoring system, the superiority of ML method was demonstrated when employing Linear SVC classifier, Naïve Bayes and Logistic. ML method could be a promising method to predict MACEs in chest pain patients with NSTE-ACS.

Objective: To analyze the relationship and consistency between indexes of different abnormal weight and dyslipidemia in adults in Beijing City. Methods: From August to December of 2017, 4 975 residents aged 18 to 79 years old in 5 districts of Beijing were randomly selected as subjects by using a multi-stage stratified cluster sampling method. Questionnaire, physical examination and laboratory tests were conducted. The prevalence of overweight/obesity, high body fat rate, central obesity, and high waist-to-height ratio was calculated. Partial correlation was used to analyze the correlation of blood lipid with body mass index (BMI), body fat rate, waist circumference and waist-height ratio. Logistic regression analysis for complex sampling was used to analyze the relationship between indexes of different abnormal weight and dyslipidemia after controlling for relevant risk factors, including age, sex, smoking status, drinking, insufficiency intake of vegetable and fruit, physical inactivity. Kappa value was computed to analyze the consistency between indexes of different abnormal weight. Results: The weighted prevalence of dyslipidemia was 30.48%, and it was higher in men than that in women (40.16% vs. 20.52%, P<0.01). The weighted rate of overweight/obesity, high body fat rate, central obesity, and high waist-to-height ratio was 56.65%, 47.52%, 42.48% and 59.45%, respectively. BMI, body fat rate, waist circumference and waist-to-height ratio were positively correlated with the level of total cholesterol, triglyceride, low-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol, and negatively correlated with high-density lipoprotein cholesterol. Logistic regression analysis for complex sampling showed that the high body fat rate (OR=1.67, 95%CI: 1.35-2.07), overweight/obesity (OR=1.65, 95%CI: 1.26-2.14) and high waist-to-height ratio (OR=1.46, 95%CI: 1.09-1.96) were associated with dyslipidemias. Kappa values of high body fat rate with overweight/obesity, high waist-to-height ratio and central obesity were 0.65, 0.53 and 0.58, respectively (P<0.05). Conclusion: In 2017, the prevalence of dyslipidemia in adults in Beijing City is high, especially in men. Overweight/obesity, high body fat rate and high waist-to-height ratio are associated with dyslipidemia. The high body fat rate is most associated with dyslipidemia.

OBJECTIVE@#To verify the safety of three dimensional printing percutaneous guide plate assisted percutaneous kyphoplasty(PKP) in the treatment of osteoporotic vertebral compression fractures(OVCFs).@*METHODS@#The clinical data of 60 patients with OVCFs treated by PKP from November 2020 to August 2021 were retrospectively analyzed. There were 24 males and 36 females, aged from 72 to 86 years old with an average of (76.5±7.9) years. Routine percutaneous kyphoplasty was performed in 30 cases (conventional group) and three dimensional printing percutaneous guide plate assisted PKP was performed in 30 cases (guide plate group). Intraoperative pedicle puncture time (puncture needle to posterior vertebral body edge) and number of fluoroscopy, total operation time, total number of fluoroscopy, amount of bone cement injection, and complication (spinal canal leakage of bone cement) were observed. The visual analogue scale (VAS) and the anterior edge compression rate of the injured vertebra were compared before operation and 3 days after operation between two groups.@*RESULTS@#All 60 patients were successfully operated without complication of spinal canal leakage of bone cement. In the guide plate group, the pedicle puncture time was(10.23±3.15) min and the number of fluoroscopy was(4.77±1.07) times, the total operation time was (33.83±4.21) min, the total number of fluoroscopy was(12.27±2.61) times;and in the conventional group, the pedicle puncture time was (22.83±3.09) min and the number of fluoroscopy was (10.93±1.62) times, the total operation time was(44.33±3.57) min, the total number of fluoroscopy was(19.20±2.67) times. There were statistically significant differences in the pedicle puncture time, intraoperative number of fluoroscopy, the total operation time, and the total number of fluoroscopy between the two groups(P<0.05). There was no significant difference in amount of bone cement injection between the two groups(P>0.05). There were no significant differences in VAS and the anterior edge compression rate of the injured vertebra at 3 days after operation between two groups(P>0.05).@*CONCLUSION@#Three dimensional printing percutaneous guide plate assisted percutaneous kyphoplasty is safe and reliable, which can reduce the number of fluoroscopy, shorten the operation time, and decrease the radiation exposure of patients and medical staff, and conforms to the concept of precise orthopaedic management.

OBJECTIVE@#To explore the serological characteristics of ABO blood group and molecular genetic mechanism for a Chinese pedigree with cisAB09 subtype.@*METHODS@#A pedigree undergoing ABO blood group examination at the Department of Transfusion, Zhongshan Hospital Affiliated to Xiamen University on February 2, 2022 was selected as the study subjects. Serological assay was carried out to determine the ABO blood group of the proband and his family members. Activities of A and B glycosyltransferases in the plasma of the proband and his mother were measured with an enzymatic assay. Expression of A and B antigens on the red blood cells of the proband was analyzed by flow cytometry. Peripheral blood samples of the proband and his family members were collected. Following extraction of genomic DNA, exons 1 to 7 of the ABO gene and their flanking introns were sequenced, and Sanger sequencing of exon 7 was carried out for the proband, his elder daughter and mother.@*RESULTS@#The results of serological assay suggested that the proband and his elder daughter and mother had an A2B phenotype, whilst his wife and younger daughter had an O phenotype. Measurement of plasma A and B glycosyltransferase activity suggested that the titers of B-glycosyltransferase activity were 32 and 256 for the proband and his mother, which were respectively below and above that of A1B phenotype-positive controls (128). Flow cytometry analysis showed that the expression of A antigen on the red blood cell surface of the proband has decreased, whilst the expression of B antigen was normal. Genetic sequencing confirmed that, in addition to an ABO*B.01 allele, the proband, his elder daughter and mother have harbored a c.796A>G variant in exon 7, which has resulted in substitution of the methionine at 266th position of the B-glycosyltransferase by valine and conformed to the characteristics of ABO*cisAB.09 allele. The genotypes of the proband and his elder daughter were determined as ABO*cisAB.09/ABO*O.01.01, his mother was ABO*cisAB.09/ABO*B.01, and his wife and younger daughter were ABO*O.01.01/ABO*O.01.01.@*CONCLUSION@#The c.796A>G variant of the ABO*B.01 allele has resulted in an amino acid substitution p.Met266Val, which probably underlay the cisAB09 subtype. The ABO*cisA B.09 allele encodes a special glycosyltransferase which can synthesize normal level of B antigen and low level of A antigen on the red blood cells.

Bisphenol A is a common environmental factor and endocrine disruptor that exerts a negative impact on male reproductive ability. By exploring bisphenol A-induced testicular cell death using the Institute of Cancer Research (ICR) mouse model, we found that a ferroptosis phenomenon may exist. Mice were divided into six groups and administered different doses of bisphenol A via intragastric gavage once daily for 45 consecutive days. Serum was then collected to determine the levels of superoxide dismutase and malondialdehyde. Epididymal sperm was also collected for semen analysis, and testicular tissue was collected for ferritin content determination, electron microscope observation of mitochondrial morphology, immunohistochemistry, real-time quantitative polymerase chain reaction, and western blot analysis. Exposure to bisphenol A was found to decrease sperm quality and cause oxidative damage, iron accumulation, and mitochondrial damage in the testes of mice. In addition, bisphenol A was confirmed to affect the expression of the ferroptosis-related genes, glutathione peroxidase 4 (GPX4), ferritin heavy chain 1 (FTH1), cyclooxygenase 2 (COX2), and acyl-CoA synthetase 4 (ACSL4) in mouse testicular tissues. Accordingly, we speculate that bisphenol A induces oxidative stress, which leads to the ferroptosis of testicular cells. Overall, the inhibition of ferroptosis may be a potential strategy to reduce male reproductive toxicity caused by bisphenol A.

Objective: To analyze the association between different treatment timings and adverse neonatal outcomes (premature birth, death, congenital syphilis) in syphilis-infected pregnant women. Methods: The National Management Information System for Prevention of HIV, Syphilis and HBV Mother-to-Child Transmission was used to collect information on the detection and treatment of syphilis-infected pregnant women and their newborns in Guangdong Province from October 2011 to December 2021. According to the gestational weeks of syphilis-infected pregnant women receiving penicillin treatment for the first time, they were divided into four groups: treatment in the first trimester, treatment in the second trimester, treatment in the third trimester, and no treatment during pregnancy. Multivariate logistic regression was used to analyze the association between different treatment timings and adverse neonatal outcomes in syphilis-infected pregnant women. Results: A total of 22 483 syphilis-infected pregnant women were included. The number of pregnant women who started treatment in the first trimester, second trimester, and third trimester and did not receive treatment during pregnancy were 4 549 (20.23%), 8 719 (38.78%), 2 235 (9.94%) and 6 980 (31.05%), respectively. Compared with pregnant women who started treatment in the first trimester, pregnant women who did not receive anti-syphilis treatment during pregnancy had increased risks of neonatal preterm birth (OR=1.42, 95%CI: 1.24-1.62), death (OR=4.27, 95%CI: 1.64-14.69) and congenital syphilis (OR=12.26, 95%CI: 6.35-27.45). At the same time, the risk of congenital syphilis in the newborns of pregnant women who started anti-syphilis treatment in the second trimester (OR=2.68, 95%CI: 1.34-6.16) and third trimester (OR=6.27, 95%CI: 2.99-14.80) also increased. Conclusion: Early initiation of anti-syphilis treatment during pregnancy in patients with syphilis can improve neonatal outcomes.

Irritable bowel syndrome (IBS) is characterized by abdominal pain associated with changes in defecation frequency and blood folate level. FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides and polyols. High-FODMAP diet could elicit or exacerbate IBS-associated bowel symptoms, which is inadequately recognized among gastroenterologists in China. Here we report an IBS case, focusing on the association between high-FODMAP diet and bowel symptoms and the intervention of low-FODMAP diet.

Objective:To investigate the clinical significance of serum 25-hydroxyvitamin D [25(OH)D] level in patients with connective tissue disease (CTD) related-pulmonary arterial hypertension (PAH).Methods:CTD patients with PAH (CTD-PAH) and without PAH (CTD-non-PAH) were colle-cted. All data were analyzed.Results:The serum 25(OH)D in the CTD-PAH group was significantly lower than that in the CTD-non-PAH group [(14±8) ng/ml vs (20±8) ng/ml, t=-5.94, P<0.001]. The 25(OH)D deficiency rate in the CTD-PAH group 86.2%(112/130) was significantly higher than that in the CTD-non-PAH group 57.7% (75/130) ( χ2=26.07, P<0.001), while the insufficiency rate was significantly lower [10.0%(13/130) vs 32.3% (42/130), χ2=19.39, P<0.001]. Serum 25(OH)D levels in the systemic lupus erythematosus (SLE), systemic sclerosis (SSc) associated PAH group were lower than those in the SLE [14(8, 17) ng/ml vs 19(15, 23) ng/ml, Z=-3.66, P<0.001], SSc [11(8, 17) ng/ml vs 24(18, 30) ng/ml, Z=-4.97, P<0.001] without PAH group. The levels of serum 25(OH)D in CTD-PAH youthful group, in the middle age group were lower than that in CTD-non-PAH youthful group [(12±8) ng/ml vs (19±8) ng/ml, t=-4.36, P<0.001] and in the middle age group [(14±7) ng/ml vs (21±8) ng/ml, t=-3.75, P<0.001]. Serum levels of 25(OH)D [ OR (95% CI)=1.100 (1.058, 1.144), P<0.001], uric acid [ OR(95% CI)=0.996(0.993, 0.998), P=0.003], immune globulin (Ig)G [ OR(95% CI)=1.123(1.057, 1.194), P<0.001] were associated with PAH in CTD patients. Serum 25(OH)D was positively correlated with calcium ( r=0.24, P=0.007), while negatively correlated between serum 25(OH)D and IgM ( r=-0.34, P<0.001). Conclusion:The occurrence and development of CTD-PAH may be related to the decrease of 25(OH)D level. Serum 25(OH)D level is associated with PAH in CTD patients.
Résumé
Objective:To study the safety and efficacy of laparoscopic cholecystectomy (LC) in treatment of T2a and lower stages of gallbladder carcinoma.Methods:A retrospective study was performed on patients who were diagnosed with gallbladder cancer and underwent surgical treatment from January 2016 to January 2021 at Hunan Provincial People's Hospital. These patients were divided into the simple treatment group and the radical treatment group based on the surgical methods used. The simple treatment group consisted of 64 patients who underwent LC for accidental gallbladder cancers. The radical treatment group consisted of 30 patients who underwent laparoscopic radical cholecystectomy (LRC). The baseline characteristic of the two groups of patients were matched in a 1∶1 ratio using propensity score matching. After matching, there were 26 patients in each of the 2 groups. There were 7 males and 19 females in the simple group, with mean ± s. d. age of (60.6±9.6) years. There were 8 males and 18 females, with mean ± s. d. age (60.9±9.1) years in the radical treatment group. Blood loss, operation time, postoperative hospital stay, biliary leakage, acute pulmonary embolism, and incisional infection were compared between the two groups.Results:In the simple group, the operative time was (78.7±62.9) min, intraoperative blood loss was (10.7±11.6) ml and postoperative hospital stay was (4.4±2.6) d. These results were significantly better than those in the radical group with operative time (298.7±101.3) min, intraoperative blood loss (161.9±96.7) ml and postoperative hospital stay (9.9±4.0) d (all P<0.05). There were no significant difference in the postoperative complications and disease free survival rates between the two groups (both P>0.05). Conclusion:LC was safe and effective for treatment of T2a and lower stages of gallbladder cancer, and it could achieve a similar disease-free survival rate as LRC.
Résumé
Bone graft materials have mixed effects of bone repair in the field of oral maxillofacial surgery. The qualitative analyses performed by previous studies imply that autogenous odontogenic materials and autogenous bone have similar effects on bone repair in clinical jaw bone transplantation. This retrospective systematic assessment and network metaanalysis aimed to analyze the best effect of clinical application of autogenous odontogenic materials and autogenous, allogeneic, and xenogeneic bone grafts in bone defect repair. A systematic review was performed by searching the PubMed, Cochrane Library, and other journal databases using selected keywords and Medical Subject Headings search terms. 10 Papers (n = 466) that met the inclusion criteria were selected. The assessment of heterogeneity did not reveal any overall statistical difference or heterogeneity (P = 0.051 [ 0.05), whereas the comparison between autogenous and allogeneic bone grafts revealed local heterogeneity (P = 0.071 0.1). Risk of bias revealed nine unclear studies and one high-risk study. The overall consistency was good (P = 0.065 [ 0.05), and the local inconsistency test did not reveal any inconsistency. The publication bias was good. The confidence regarding the ranking of bone graft materials after GRADE classification was moderate. The effects on bone repair in the descending order were as follows: autogenous odontogenic materials, xenogeneic bone, autogenous bone, and allogeneic bone. This result indicates that the autogenous odontogenic materials displayed stronger effects on bone repair compared to other bone graft materials. Autogenous odontogenic materials have broad development prospects in oral maxillofacial surgery.
Résumé
Objective: To explore the knowledge, attitude and behavior of salt reduction in adults of Beijing in 2017. Methods: Based on the monitoring data of chronic diseases and corresponding risk factors in adults of Beijing in 2017, the indicators of salt reduction knowledge, attitude and behavior of 13 240 participants aged 18-79 years old were analyzed. The awareness rate, attitude support rate and behavior rate were calculated by complex weighting method, and compared among different age groups, genders, residential areas, and history of hypertension. The proportion of people taking various salt reduction measures to the total number of people was compared. Results: The awareness rate of recommended daily salt intake, the awareness of hypertension caused or aggravated by more salt intake, the attitude support rate and behavior rate of adults were 31.77%, 88.56%, 90.27% and 53.86%, respectively. After weighted adjustment, the awareness rate of recommended daily salt intake was 31.08%, which increased with age (χ2trend=431.56, P<0.001) and education level (χ2trend=95.44, P<0.001). The awareness rate of women was higher than that of men (χ²=118.89, P<0.001), and the awareness rate of population in urban areas was higher than that of population in suburban areas (χ²=34.09, P=0.001). The awareness rate of hypertension caused or aggravated by eating more salt was 86.73%. The support rate of salt reduction attitude was 90.45%. The rate of salt-reducing behavior was 54.05%. Among different salt reduction measures, reducing salt when cooking was the most common measure (52.41%), while the least common one (35.22%) was using low sodium salt. Logistic regression model analysis showed that the gender, age, education level, self-reported history of hypertension, awareness of salt recommendation, awareness of hypertension caused or aggravated by eating more salt, and salt reduction attitude were significantly associated with salt reduction behavior. Conclusion: In 2017, adults in Beijing have a basic understanding of the impact of high-salt diet on health and support salt reduction, but the rate of salt reduction behavior is still relatively low. There are obvious gender and age differences, and the salt reduction measure is simple. Targeted measures should be taken to promote the formation of salt reduction behavior.
