ABSTRACT
Objective To investigate and analyze the risk factors of Helicobacter pylori (Hp) infection and the immunological classification of Hp-infected people in community health examination population. Methods Among of the 2 475 residents in a community who underwent health examination in Guangyuan First People's Hospital were selected between July 2022 and April 2023. Western blotting was used to detect and type the Hp antibodies. The risk factors of Hp infection in the community residents were analyzed by binary logistic regression analysis, and the results of immunological typing were compared among patients with different upper digestive tract diseases and chronic diseases. Results The Hp infection rate among of the 2 475 residents who underwent physical examination was 35.64% (882/2475), and the positive rates of type I Hp antibody and type II Hp antibody were 23.72% (587/2 475) and 11.92% (295/2 475) , respectively. There were significant differences in Hp infection rates in gender, age, smoking history, and whether or not people had diabetes (P<0.05). Multivariate logistic regression analysis showed that male, age ≥60 years old, drinking history and diabetes were risk factors of Hp infection in the community health examination population (P<0.05). The positive rate of type I Hp antibody in men and patients with coronary heart disease was higher than that in women and patients without coronary heart disease (P<0.05). Conclusion The infection rate of Hp among health examination population in this community is low, mainly type I. Hp infection is affected by gender, age, drinking history and diabetes. There are more males in the population with type I Hp antibody positivity, and the risk may be higher in patients with coronary heart disease. Clinically, it is necessary to take susceptible population as the focus of prevention and treatment, and take targeted monitoring and diagnosis and treatment measures.
ABSTRACT
Objective:To investigate the relationship between cardiometabolic index (CMI) and hyperuricemia (HUA) in the health examination population.Methods:It was a cross-sectional study. A total of 21 720 individuals who received health examinations in Xiangya hospital, Central South University between 2020 and 2021 were recruited in this study. Multivariate logistic regression analysis was used to determine the independent correlation between CMI and HUA, and stratified analysis was applied to check whether there were population differences. Then the predictive value of CMI for hyperuricemia in the health examination population was evaluated with the area under the receiver operator characteristic (ROC) curve.Results:Among the 21 720 subjects, 4 418 (20.34%) were detected with HUA. In the HUA group, the body mass index (BMI), waist-to-hip ratio, CMI, total cholesterol, triglyceride, systolic blood pressure, diastolic blood pressure, fasting blood glucose, 2-hour postprandial blood glucose, and blood creatinine levels were all significantly higher than those in the normal uric acid group, while high-density lipoprotein and epidermal growth factor receptor (eGFR) were significantly lower (all P<0.05). Multiple logistic regression analysis showed that after adjusting for relevant factors, CMI was significantly positively correlated with HUA ( OR=1.16, 95% CI: 1.129-1.192); and with the increase of CMI, the risk of HUA increased gradually. Stratified analysis and interaction test according to gender, age, BMI, hypertension, abnormal blood glucose and glomerular filtration rate indicated that CMI was positively associated with the occurrence of HUA in all populations. Compared with that in people with abnormal blood glucose, the correlation between CMI and HUA was more obvious in people with normal blood glucose. The area under the ROC curve (AUC) for CMI to predict HUA was 0.723(95% CI: 0.715-0.731), with a specificity of 0.636 and a sensitivity of 0.698, and the cut-point was 0.693. Conclusion:There was a significant positive correlation between CMI and HUA in the health examination population, which has good predictive value for HUA.
ABSTRACT
Objective To analyze the prevalence and risk factors of hyperuricemia (HUA) in Shenyang City, and to provide evidence for the prevention and treatment of HUA in this region. Methods From January 2013 to December 2020, 98,327 subjects who underwent physical examination in Shengjing Hospital of China Medical University in Shenyang were selected. The detection rate of HUA was calculated, and the risk factors of HUA were analyzed by multivariate logistic regression analysis. Results From 2013 to 2020, the overall prevalence of HUA was 22.48%, 30.75% in males and 9.13% in females. The prevalence rate in the male was significantly higher than that in the female (P<0.05). Except for a slight decrease in 2015 and 2020, the total prevalence rate showed an increasing trend year by year. With the increase of age, the prevalence of HUA in males decreased, while in females, it decreased slightly from 40 to 59 years old and increased significantly after 60 years old. With the increase of BMI (Body Mass Index), the prevalence of HUA also increased, and the difference was statistically significant (P<0.05). Logistic regression analysis showed that male, body mass index, physical examination year, hypertension, hyperlipidemia, hyperglycemia, triglyceride, LDL-C, abnormal liver and renal function were positively correlated with HUA, while age and HDL-C were negatively correlated with HUA. Conclusion HUA occurs mainly in male people among physical examination population in Shenyang. With the increase of BMI, HUA increases.
ABSTRACT
Objective To analyze the screening results of tumor markers carbohydrate antigen 724 (CA-724), carbohydrate antigen 153 (CA-153), carbohydrate antigen 125 (CA-125), carbohydrate antigen 199 (CA-199) and carcinoembryonic antigen (CEA) in the 45 ~ 60-year-old health examination population in Chengdu area. Methods A total of 2 268 healthy people aged 45 ~ 60 years old living in Chengdu area from May 2019 to August 2020 were selected. Levels of serum tumor markers CA-724, CA-153, CA-125, CA-199 and CEA were detected by electrochemiluminescence. Positive rates of different tumor markers and confirmed diagnosis of malignant tumors were statistically analyzed. People with positive and negative tumor markers were respectively included in the positive group and the negative group, and their serum tumor markers were compared. The screening results of tumor markers in the health examination population of different gender and age, and the diagnostic efficiency of each tumor marker for malignant tumors were analyzed. Results Among the 2 268 healthy people, the positive rates of CA-724, CA-153, CA-125, CA-199 and CEA were 10.05%, 4.98%, 1.10%, 7.01% and 4.76%, respectively. A total of 72 cases were positive for tumor marker detection, with a total positive rate of 3.17% (72/2,268). Among them, 12 cases were diagnosed as early or mid-term tumors by pathology, imaging and other examinations, with a total tumor detection rate of 0.53% (12/2,268), including 8 cases of malignant tumors, with a detection rate of 0.35% (8/2,268). The levels of CA-724, CA-153, CA-125, CA-199 and CEA in the tumor markers positive group were higher than those in the negative group (P<0.05). The CA-125 and CA-199 positive rates in males were lower than those in females, while CEA positive rate was higher in males than in females (P<0.05). Positive rates of CA-153, CA-199 and CEA in different age groups showed statistically significant differences (P<0.05). Positive expression of CA-153 and CA-199 mainly occurred in the 51~60 years old group, and positive expression of CEA mainly occurred in the 45~50 years old group. ROC curve analysis showed that combined detection of CA-724, CA-153, CA-125, CA-199 and CEA had the highest sensitivity, specificity and accuracy in predicting malignant tumors, and the area under the curve was the largest (0.865). Conclusion Tumor markers CA-724, CA-153, CA-125, CA-199 and CEA are highly expressed in the 45 ~ 60-year-old health examination population in Chengdu area, and positive rate of CA-724 is the highest. Levels of tumor markers in people of different gender and age are also different. Joint detection of various tumor markers is conducive to early detection and treatment of the disease, and reduction of deterioration risk.
ABSTRACT
Objective To design a simple screening tool for non-alcoholic fatty liver disease based on Chinese healthy physical examination population. Methods Subjects were selected from the health management center of China Medical University since January 2017 to December 2017. A total of 32,578 subjects were included. 80% subjects were randomly selected as the training set for modeling and internal assessment, and the remaining 20% subjects were used as the verification set for external assessment. Stepwise logistic regression analysis was used to construct the NAFLD screening index. Results Multivariate regression analysis showed that body mass index (BMI), fasting glucose (FPG), serum triglyceride (TG), and aspartate aminotransferase/alanine aminotransferase (AST/ALT) were included in the NAFLD screening model. The constructed NAFLD screening index was 2×BMI+FPG+3×TG-7×(AST/ALT). The AUC of the index was 0.883 [95%CI (0.879, 0.887)] in the training set and was 0.888 [95%CI (0.880, 0.896)] in the verification set. Conclusion The NAFLD screening index, as a simple and effective screening tool, can be used to screen large-scale population at high risk, which has certain epidemiological and health economic significance.
ABSTRACT
Objective To assess the predictive value of serum uric acid levels to the incident nonalcoholic fatty liver disease(NAFLD)in a cohort of healthy population. Methods A prospective cohort study of NAFLD incidence was conducted in Xinjiang province, from 2012 to 2014. A cohort study was performed on 2 207 subjects with no evidence of fatty liver disease by liver ultrasound and with no major risk factors for liver disease at baseline. All participants were interviewed to carry out the epidemiological questionnaire survey, physical examination, abdominal ultrasonography, as well as blood biochemistry measurements. The hazard ratios of NAFLD were compared among groups with different uric acid levels. All subjects were classified according to serum uric acid (within normal range grouped by quartile: Q1-Q4 group; above the normal range: Q5 group). Results NAFLD was newly diagnosed in 13.72% subjects within the 3-year period. The incidence of NAFLD was increased with elevated serum uric acid quartiles(P<0.01). In multivariate logistic regression, after adjustment for gender, age, race, metabolic syndrome and its components, OR for incident fatty liver in Q2 to Q5 of serum uric acid concentration as compared to Q1 were 2.509, 3.172, 3.392, and 4.041 respectively. Conclusion Elevated serum uric acid concentrations may predict NAFLD in the subjects for a regular health checkup.
