In 2019, cardiovascular disease (CVD) accounted for 46.74% and 44.26% of all deaths in rural and urban areas, respectively. Two out of every five deaths were due to CVD. It is estimated that about 330 million patients suffer from CVD in China. The number of patients suffering from stroke, coronary heart disease, heart failure, pulmonary heart disease, atrial fibrillation, rheumatic heart disease, congenital heart disease, lower extremity artery disease and hypertension are 13.00 million, 11.39 million, 8.90 million, 5.00 million, 4.87 million, 2.50 million, 2.00 million, 45.30 million, and 245.00 million, respectively. Given that China is challenged by the dual pressures of population aging and steady rise in the prevalence of metabolic risk factors, the burden caused by CVD will continue to increase, which has set new requirements for CVD prevention and treatment and the allocation of medical resources in China. It is important to reduce the prevalence through primary prevention, increase the allocation of medical resources for CVD emergency and critical care, and provide rehabilitation services and secondary prevention to reduce the risk of recurrence, re-hospitalization and disability in CVD survivors. The number of people suffering from hypertension, dyslipidemia and diabetes in China has reached hundreds of millions. Since blood pressure, blood lipids, and blood glucose levels rise mostly insidiously, vascular disease or even serious events such as myocardial infarction and stroke often already occured at the time of detection in this population. Hence, more strategies and tasks should be taken to prevent risk factors such as hypertension, dyslipidemia, diabetes, obesity, and smoking, and more efforts should be made in the assessment of cardiovascular health status and the prevention, treatment, and research of early pathological changes.

In the past 30 years, the accessibility and quality index of medical care have made remarkable progress in China, ranking the first among middle-income countries. Many cardiovascular technologies are at or near the world's leading level, and significant progress has been achieved in China solving the problem of “treatment difficulty” of cardiovascular diseases (CVD). However, due to the prevalence of unhealthy lifestyles among Chinese residents, a huge population with CVD risk factors, accelerated population aging, and other reasons, the incidence and mortality rate of CVD are still increasing, and the turning point of the decline in disease burden has not appeared yet in China. In terms of proportions of disease mortality among urban and rural residents, CVD still ranks the first. In 2020, CVD accounted for 48.00% and 45.86% of the causes of death in rural and urban areas, respectively; two out of every five deaths were due to CVD. It is estimated that the number of current CVD patients in China is around 330 million, including 13 million stroke, 11.39 million coronary heart disease, 8.9 million heart failure, 5 million pulmonary heart disease, 4.87 million atrial fibrillation, 2.5 million rheumatic heart disease, 2 million congenital heart disease, 45.3 million peripheral artery disease, and 245 million hypertension cases. China has entered a new stage of transformation from high-speed development to high-quality development, and the prevention and control of CVD in China should also shift from previous emphasis on scale growth to strategies focusing more on strategic and key technological development in order to curb the trend of increasing incidence and mortality rates of CVD.

YANG Zuo Sen, BAI Ying Long, JIN Cui Hong, NA Jun, ZHANG Rui, GAO Yuan, PAN Guo Wei, YAN Ling Jun, SUN Wei
2022, 35(11): 1025-1037. doi: 10.3967/bes2022.131
  Objective  This study was designed to provide the evidences on the toxicokinetics of microplastics (MPs) and nanoplastics (NPs) in the bodies of mammals.  Methods  100 nm, 3 μm, and 10 μm fluorescent polystyrene (PS) beads were administered to mice once by gavage at a dose of 200 mg/kg body weight. The levels and change of fluorescence intensity in samples of blood, subcutaneous fat, perirenal fat, peritesticular fat, cerebrum, cerebellum, testis, and epididymis were measured at 0.5, 1, 2, and 4 h after administration using an IVIS Spectrum small-animal imaging system. Histological examination, confocal laser scanning, and transmission electron microscope were performed to corroborate the findings.  Results  After confirming fluorescent dye leaching and impact of pH value, increased levels of fluorescence intensity in blood, all adipose tissues examined, cerebrum, cerebellum, and testis were measured in the 100 nm group, but not in the 3 and 10 μm groups except in the cerebellum and testis at 4 h for the 3 μm PS beads. The presence of PS beads was further corroborated.  Conclusion  After a single oral exposure, NPs are absorbed rapidly in the blood, accumulate in adipose tissues, and penetrate the blood-brain/testis barriers. As expected, the toxicokinetics of MPs is significantly size-dependent in mammals.

  Objective  To improve the understanding of the virome and bacterial microbiome in the wildlife rescue station of Poyang Lake, China.  Methods  Ten smear samples were collected in March 2019. Metagenomic sequencing was performed to delineate bacterial and viral diversity. Taxonomic analysis was performed using the Kraken2 and Bracken methods. A maximum-likelihood tree was constructed based on the RNA-dependent RNA polymerase (RdRp) region of picornavirus.  Results  We identified 363 bacterial and 6 viral families. A significant difference in microbial and viral abundance was found between samples S01–S09 and S10. In S01–S09, members of Flavobacteriia and Gammaproteobacteria were the most prevalent, while in S10, the most prevalent bacteria class was Actinomycetia. Among S01–S09, members of Myoviridae and Herelleviridae were the most prevalent, while the dominant virus family of S10 was Picornaviridae. The full genome of the pigeon mesivirus-like virus (NC-BM-233) was recovered from S10 and contained an open reading frame of 8,124 nt. It showed the best hit to the pigeon mesivirus 2 polyprotein, with 84.10% amino acid identity. Phylogenetic analysis showed that RdRp clustered into Megrivirus B.  Conclusion  This study provides an initial assessment of the bacteria and viruses in the cage-smeared samples, broadens our knowledge of viral and bacterial diversity, and is a way to discover potential pathogens in wild birds

2023, 36(7): 625-634. doi: 10.3967/bes2023.089
  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.

2023, 36(7): 585-594. doi: 10.3967/bes2023.086
  Objective  To determine the thermic effect of food (TEF) in a Chinese mixed diet in young people.  Methods  During the study, the participants were weighed and examined for body composition every morning. The total energy expenditure (TEE) of the participants was measured by the doubly labeled water method for 7 days, and during this period, basal energy expenditure was measured by indirect calorimetry and physical activity energy expenditure was measured by an accelerometer. The value obtained by subtracting basal energy expenditure and physical activity energy expenditure from TEE was used to calculate TEF.  Results  Twenty healthy young students (18–30 years; 10 male) participated in the study. The energy intake of the participants was not significantly different from the Chinese Dietary Reference Intake of energy (P > 0.05). The percentage of energy from protein, fat and carbohydrate were all in the normal range. The intakes of fruits, milk and dietary fiber of the participants were significantly lower than those in the Chinese Dietary Guidelines (P < 0.05). There was no significant difference in the body weight of the participants during the experiment (P > 0.05). When adjusted for body weight, there was no significant difference in either TEE or basal energy expenditure between the male and female participants (P > 0.05). In addition, there was no significant difference in physical activity energy expenditure and TEF between the male and female participants (P > 0.05). The percentage of TEF in TEE was 8.73%.  Conclusion  The percentage of TEF in TEE in a Chinese mixed diet in young people was significantly lower than 10% (P < 0.001). A value of 10% is usually considered to be the TEF in mixed diets as a percentage of TEE.

  Objective  This study aimed to assess the relationship between the body composition of children aged 3–5 years and breastfeeding status and duration.  Methods  The study was conducted using data from the National Nutrition and Health Systematic Survey for children 0–17 years of age in China (CNHSC), a nationwide cross-sectional study. Breastfeeding information and potential confounders were collected using standardized questionnaires administered through face-to-face interviews. The body composition of preschool children was measured using bioelectrical impedance analysis. A multivariate linear regression model was used to assess the relationship between breastfeeding duration and body composition after adjusting for potential confounders.  Results  In total, 2,008 participants were included in the study. Of these, 89.2% were ever breastfed and the median duration of breastfeeding was 12 months (IQR 7–15 months). Among children aged 3 years, the height-for-age Z-score (HAZ) for the ever breastfed group was lower than that for never breastfed group (0.12 vs. 0.42, P = 0.043). In addition, the weight-for-age Z-score (WAZ) of the ever breastfed group was lower than that of the never breastfed group (0.31 vs. 0.65, P = 0.026), and the WAZ was lower in children aged 4 years who breastfed between 12 and 23 months than in those who never breastfed. Compared to the formula-fed children, the fat-free mass of breastfed infants was higher for children aged 3 years (12.84 kg vs. 12.52 kg, P = 0.015) and lower for those aged 4 years (14.31 kg vs. 14.64 kg, P = 0.048), but no difference was detected for children aged 5 years (16.40 kg vs. 16.42 kg, P = 0.910) after adjusting for potential confounders. No significant difference was detected in the weight-for-height Z-score (WHZ), body mass index (BMI)-for-age Z-score (BAZ), fat-free mass index, and body fat indicators in the ever breastfed and never breastfed groups and among various breastfeeding duration groups for children aged 3–5 years.  Conclusion  No obvious associations were detected between breastfeeding duration, BMI, and fat mass indicators. Future prospective studies should explore the relationship between breastfeeding status and fat-free mass.

Objective To investigate the trends of lipid profiles and dyslipidemia among Chinese adults from 2002 to 2015. Methods Data were collected from three nationally representative cross-sectional surveys. Fasting venous blood samples were collected and serum lipids were tested by biochemical analysis and enzymatic determination. Lipid levels and the prevalence of dyslipidemia among adults were analyzed with complex sampling weighting adjustment for age and gender. Results The weighted means of TC, TG, and LDL-c significantly increased linearly from 3.93, 1.12, and 2.12 mmol/L in 2002 to 4.59, 1.41, and 2.78 mmol/L in 2010 and then to 4.63, 1.47, and 2.87 mmol/L in 2015, respectively; by contrast, HDL-c levels decreased significantly from 1.30 mmol/L to 1.26 mmol/L over the same period. Similar trends in mean non-HDL-c and lipid-related ratios were observed. The weighted dyslipidemia prevalence linearly increased; in particular, hypercholesterolemia increased from 1.6% to 5.6% and then to 5.8%, hypertriglyceridemia increased from 5.7% to 13.6% and then to 15.0%, low HDL-c increased from 18.8% to 35.5% and then to 24.9%, and high LDL-c increased from 1.3% to 5.6% and then to 7.2% (P for trend < 0.001). Conclusion Dyslipidemia increased among Chinese adults from 2002 to 2015. Development of a comprehensive strategy to decrease lipid levels in this population is urgently required.

2020, 33(1): 1-10. doi: 10.3967/bes2020.001
Objective To estimate the burden of cirrhosis and other chronic liver diseases caused by specific etiologies in China. Methods Data from the Global Burden of Disease Study 2016 (GBD 2016) were used. We evaluated the burden by analyzing age-sex-province-specific prevalence, mortality, and disability-adjusted life-years (DALYs) of 33 provinces in China. Results From 1990 to 2016, prevalence cases in thousands increased by 73.7% from 6833.3 (95% UI: 6498.0–7180.6) to 11869.6 (95% UI: 11274.6–12504.7). Age-standardized mortality and DALY rates per 100,000 decreased by 51.2% and 53.3%, respectively. Male and elderly people (aged ≥ 60 years) preponderance were found for prevalence, mortality, and DALYs. The number of prevalence cases, deaths, and DALYs due to hepatitis C virus (HCV) increased by 86.6%, 8.7%, and 0.9%, respectively. Also, age-standardized prevalence rates decreased in 31 provinces, but increased in Yunnan and Shandong. The Socio-demographic Index (SDI) values were negatively correlated with age-standardized mortality and DALY rates by provinces in 2016; the correlation coefficients were −0.817 and −0.828, respectively. Conclusion Cirrhosis and other chronic liver diseases remain a huge health burden in China, with the increase of population and the aging of population. Hepatitis B virus (HBV) remains the leading cause of the health burden in China.

2017, 30(1): 1-9. doi: 10.3967/bes2017.001
Objective Assessment of the comprehensive relationship among apolipoprotein CIII (apoCIII) levels, inflammation, and metabolic disorders is rare. Methods A total of 1455 consecutive patients not treated with lipid-lowering drugs and undergoing coronary angiography were enrolled in this cross-sectional study. A mediation analysis was used to detect the underlying role of apoCIII in the association of inflammation with metabolic syndrome (MetS). Results Patients with MetS showed higher levels of apoCIII[95.1 (73.1-131.4) vs. 81.7 (58.6-112.4) μg/mL, P<0.001] and inflammatory markers[high sensitivity C-reactive protein, 1.7 (0.8-3.4) vs. 1.1 (0.5-2.2) mg/L; white blood cell count, (6.48±1.68) vs. (6.11±1.67)×109/L]. The levels of apoCIII and inflammatory markers increased with the number of metabolic risk components (all P<0.001). Furthermore, apoCIII levels were associated with virtually all individual MetS risk factors and inflammatory markers (all P<0.05). Importantly, the prevalence of MetS in each metabolic disorder rose as apoCIII levels increased (all P<0.05). Mediation analysis showed that apoCIII partially mediated the effect of inflammation on MetS independently from triglycerides. Conclusion Plasma apoCIII levels were significantly associated with the development and severity of MetS, and a role of apoCIII in the effect of inflammation on the development of MetS was identified.
Application of Nanopore Sequencing Technology in the Clinical Diagnosis of Infectious Diseases (365 day view times: 134)
2022, 35(5): 381-392. doi: 10.3967/bes2022.054
Abstract: Infectious diseases are an enormous public health burden and a growing threat to human health worldwide. Emerging or classic recurrent pathogens, or pathogens with resistant traits, challenge our ability to diagnose and control infectious diseases. Nanopore sequencing technology has the potential to enhance our ability to diagnose, interrogate, and track infectious diseases due to the unrestricted read length and system portability. This review focuses on the application of nanopore sequencing technology in the clinical diagnosis of infectious diseases and includes the following: (i) a brief introduction to nanopore sequencing technology and Oxford Nanopore Technologies (ONT) sequencing platforms; (ii) strategies for nanopore-based sequencing technologies; and (iii) applications of nanopore sequencing technology in monitoring emerging pathogenic microorganisms, molecular detection of clinically relevant drug-resistance genes, and characterization of disease-related microbial communities. Finally, we discuss the current challenges, potential opportunities, and future outlook for applying nanopore sequencing technology in the diagnosis of infectious diseases.
