Since 1990, China has made considerable progress in resolving the problem of “treatment difficulty” of cardiovascular diseases (CVD). The prevalent unhealthy lifestyle among Chinese residents has exposed a massive proportion of the population to CVD risk factors, and this situation is further worsened due to the accelerated aging population in China. CVD remains one of the greatest threats to the health of Chinese residents. In terms of the proportions of disease mortality among urban and rural residents in China, CVD has persistently ranked first. In 2021, CVD accounted for 48.98% and 47.35% of deaths in rural and urban areas, respectively. Two out of every five deaths can be attributed to CVD. To implement a national policy “focusing on the primary health institute and emphasizing prevention” and truly achieve a shift of CVD prevention and treatment from hospitals to communities, the National Center for Cardiovascular Diseases has organized experts from relevant fields across China to compile the “Report on Cardiovascular Health and Diseases in China” annually since 2005. The 2024 report is established based on representative, published, and high-quality big-data research results from cross-sectional and cohort population epidemiological surveys, randomized controlled clinical trials, large sample registry studies, and typical community prevention and treatment cases, along with data from some projects undertaken by the National Center for Cardiovascular Diseases. These firsthand data not only enrich the content of the current report but also provide a more timely and comprehensive reflection of the status of CVD prevention and treatment in China.

  Objective   To examine national trends in antibiotic consumption and antimicrobial resistance (AMR) among six WHO-priority bacterial pathogens in China from 2016 to 2022.  Methods   This ecological study analyzed national and provincial data from the China Antibacterial Resistance Surveillance System (CARSS) and the National Hospital Information Network. Beta regression models assessed temporal trends, and hierarchical models evaluated associations between antibiotic use and resistance.  Results   From 2016 to 2022, carbapenem resistance in Acinetobacter baumannii and Pseudomonas aeruginosa, and vancomycin resistance in Enterococcus faecium and E. faecalis significantly declined (β < 0, P < 0.010), while carbapenem-resistant Klebsiella pneumoniae increased (β = 0.081, P < 0.001). Nationwide antibiotic consumption rose across 10 major classes. Positive associations were found between carbapenem use and resistance in A. baumannii (z = 2.719, P = 0.007) and P. aeruginosa (z = 3.241, P = 0.001), and between vancomycin use and resistance in E. faecium (z = 4.510, P = 0.001) and E. faecalis (z = 3.210, P = 0.001).  Conclusion   Carbapenem-resistant K. pneumoniae increased significantly in China, while other resistant pathogens declined. Resistance patterns were linked to the use of multiple antibiotic classes, underscoring the need for strengthened antibiotic stewardship and surveillance.

2026, 39(2): 131-145. doi: 10.3967/bes2025.159
  Objective  To determine the proportions of drug-resistant tuberculosis (TB), its trends, and the drug resistance-conferring mutations among patients with pulmonary TB aged 10–24 years in China.  Methods  The data of patients with pulmonary TB were retrieved from a national drug-resistant TB survey for analysis. Joinpoint regression software was used to analyze time trends. We also used whole genome sequencing to analyze the lineages and drug resistance-conferring mutations of 621 isolates.  Results  Among 4,235 patients with pulmonary TB, the proportion of new cases of multidrug-resistant tuberculosis (MDR-TB) was 3.18% (95% confidence interval [CI]: 2.37–4.15) for adolescents and 3.76% (95% CI: 3.03–4.60) for young adults; for previously treated patients, MDR-TB accounted for 11.25% (95% CI: 5.28–20.28) of adolescents and 11.05% (95% CI: 6.88–16.55) of young adults. The proportion of patients with MDR-TB remained stable among both new and previously treated patients aged 10–24 years during the study period. Through whole genome sequencing, we found that the most common mutations in the MDR-TB strains were Ser315Thr in the katG gene (71.74%) and Ser450Leu in the rpoB gene (50.00%).  Conclusion  This study revealed a high proportion of MDR-TB among adolescents and young adults, indicating that urgent and comprehensive measures are needed to reduce the emergence and transmission of drug-resistant TB among this population in China.

2026, 39(1): 82-104. doi: 10.3967/bes2025.104
Human cardiac organoids have revolutionized the study of cardiac development, disease modeling, drug discovery, and regenerative therapies. This review systematically discusses strategies and progress in the construction of cardiac organoids, categorizing them into three main types: cardiac spheroids, self-organizing/assembloid organoids, and organoid-on-a-chip systems. This review uniquely integrates the advances in vascularization, organ-on-chip design, and environmental cardiotoxicity modeling within cardiac organoid platforms, offering a critical synthesis that is absent in the literature. In the context of escalating environmental threats to cardiovascular health, there is an urgent need for physiologically relevant models to accurately identify cardiac toxicants and elucidate their underlying mechanisms of action. This review highlights advances in cardiac organoid applications for disease modeling—including congenital heart defects and acquired cardiovascular diseases—drug development, toxicity screening, and the study of environmentally induced cardiovascular pathogenesis. In addition, it critically examines ongoing challenges and underscores opportunities brought by bioengineering approaches. Finally, we propose future directions for developing standardized cardiac organoid platforms with clinical predictability, aiming to expand the utility of this technology across broader research applications.

Lulu Zhang, Junping Peng
2026, 39(2): 223-233. doi: 10.3967/bes2025.164
Tuberculosis (TB) continues to pose a significant threat to global public health, necessitating rapid and precise diagnostic methods and comprehensive detection of antimicrobial resistance (AMR) to facilitate timely clinical management. Traditional diagnostic techniques suffer from extended turnaround times and limited ability to comprehensively profile AMR, often resulting in delayed therapeutic interventions. High-throughput sequencing (HTS) technologies have revolutionized pathogen research by significantly improving diagnostic speed and accuracy. In the context of TB, diverse sequencing strategies and platforms are being employed to fulfill specific research goals, ranging from elucidating the molecular mechanisms underlying AMR to characterizing the genomic diversity among clinical isolates. This review systematically examines current progress in the application of HTS for rapid pathogen identification, comprehensive AMR profiling, epidemiological studies, advances in novel drugs, and vaccine development. Furthermore, we address existing technological limitations and bioinformatics challenges and explore the future directions necessary for effectively integrating HTS-based methodologies into global TB control efforts.

2023, 36(8): 669-701. doi: 10.3967/bes2023.106
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.

Hypertrophic cardiomyopathy (HCM) is a major contributor to cardiovascular diseases (CVD), the leading cause of death globally. HCM can precipitate heart failure (HF) by causing the cardiac tissue to weaken and stretch, thereby impairing its pumping efficiency. Moreover, HCM increases the risk of atrial fibrillation, which in turn elevates the likelihood of thrombus formation and stroke. Given these significant clinical ramifications, research into the etiology and pathogenesis of HCM is intensifying at multiple levels. In this review, we discuss and synthesize the latest findings on HCM pathogenesis, drawing on key experimental studies conducted both in vitro and in vivo. We also offer our insights and perspectives on these mechanisms, while highlighting the limitations of current research. Advancing fundamental research in this area is essential for developing effective therapeutic interventions and enhancing the clinical management of HCM.

2026, 39(2): 146-157. doi: 10.3967/bes2025.121
  Objective   Post tuberculosis lung disease (PTLD) manifests in various forms, including tuberculosis-associated chronic obstructive pulmonary disease (TB-COPD), yet the clinical features of PTLD remain undercharacterized. This study aimed to assess longitudinal changes in lung function over a 5-year period and to identify predictors of airflow obstruction in a cohort of patients treated for active pulmonary TB.  Methods   Patients with active pulmonary TB were enrolled in this study and were followed during treatment, at treatment completion and five years post-treatment. Assessments included lung function and chest CT, analyzing longitudinal trends and airflow obstruction risk factors.  Results   Among 53 patients (mean age 36.9 ± 13.9 years; 64.2% male), 7 patients (13.2%) exhibited airflow obstruction. At the 5-year follow-up, the mean FEV1/FVC declined significantly (76.27% ± 12.04% vs. 80.23% ± 11.02%, P < 0.001) and 9 patients (17.0%) exhibited airflow obstruction. Seven of these patients predominantly showed air trapping consistent with small airway disease on chest CT, aligning with TB-COPD phenotype. Notably, four young-to-middle-aged patients (< 60 years old) had persistent obstruction over the five years.  Conclusion   The initial test revealed that 13.2% of patients presented with airflow obstruction. By the 5-year follow-up, this proportion had increased to 17.0%, with most cases demonstrating imaging findings aligning with TB-COPD, even among younger, non-smoking individuals. These findings emphasize the importance of long-term follow-up and routine lung function assessments in TB survivors.

Climate and weather significantly influence the duration, timing, and intensity of disease outbreaks, reshaping the global landscape of infectious diseases. Rising temperatures and shifts in precipitation patterns driven by climate change can directly impact the survival and reproduction of pathogens and vector organisms. Moreover, climate change is expected to exacerbate extreme weather events, including floods and droughts, which can disrupt infrastructure and increase the risk of water- and foodborne diseases. There are potential shifts in the temporal and spatial patterns of infectious disease transmission owing to climate change. Furthermore, climate change may alter the epidemiology of vaccine-preventable diseases. These climatic variations not only affect the ecological characteristics of pathogens and vectors but also indirectly influence human behaviors and socioeconomic conditions, further amplifying disease transmission risks. Addressing this challenge requires an interdisciplinary collaboration and comprehensive public health strategies. This review aims to synthesize the current evidence on the impact of climate change on climate-sensitive infectious diseases and elucidate the underlying mechanisms and transmission pathways. Additionally, we explored adaptive policy strategies to mitigate the public health burden of infectious diseases in the context of climate change, offering insights for global health governance and disease control efforts.

2026, 39(2): 202-214. doi: 10.3967/bes2025.162
  Objective  Previous Mendelian randomization (MR) studies have suggested an association between the gut microbiome and metabolic-associated fatty liver disease (MAFLD). However, the reliance on 16S rRNA sequencing data has led to inconsistent findings and limited species-level insights. To address this, we conducted a de novo MR analysis using species-level shotgun metagenomic data, combined it with a meta-analysis to consolidate the existing evidence, and explored metabolite-mediated pathways.  Methods  Bidirectional MR analyses were performed between 883 gut microbiota taxa (derived from shotgun metagenomic genome-wide association study) and MAFLD. Published MR studies (up to December 1, 2024) were identified using PubMed, Embase, Web of Science, and the Cochrane Library for meta-analysis. Multivariable MR (MVMR) and mediation analyses were applied to assess the mediating effects of 1,400 blood metabolites.  Results  The de novo MR identified 25 MAFLD-associated microbial taxa. Integration with 7 published studies revealed 34 causal taxa, including 10 at the species level. Among the 1,400 metabolites, 53 showed causal links with MAFLD. MVMR and mediation analyses identified deoxycholate as a mediator of the effect of Bifidobacterium on MAFLD risk (22.06% mediation proportion).  Conclusion  This study elucidated the connections between species-level gut microbiota and MAFLD, highlighting the interplay between microbiota, metabolites, and disease pathogenesis. These findings provide novel insights into the potential therapeutic targets for MAFLD.

2026, 39(2): 183-191. doi: 10.3967/bes2025.094
  Objective  The associations of serum trace element levels with disease progression and survival duration were assessed in individuals diagnosed with sporadic amyotrophic lateral sclerosis (sALS) in China.  Methods  Clinical data, including diagnostic indicators, clinical characteristics, Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) scores, and serum concentrations of calcium (Ca), magnesium (Mg), iron (Fe), copper (Cu), and zinc (Zn), were collected for hospitalized patients with sALS between 2018 and 2021. Correlation analysis, random forest analysis, and the Gehan–Breslow–Wilcoxon test were used to evaluate the relations between serum trace element levels, disease progression, and survival duration.  Results  Lower serum Ca levels and higher Mg levels were observed in patients with ALSFRS-R scores < 39. Serum Mg was significantly negatively correlated with ALSFRS-R, trunk, and respiratory scores. Serum Cu and Zn also showed significant negative correlations with the respiratory score, whereas Ca and Fe were not significantly correlated with the ALSFRS-R score. The serum levels of Ca, Mg, Cu, Zn, and Fe remained consistent regardless of the site of disease onset. ALSFRS-R analysis revealed that serum Ca and Mg had a substantial effect on the total ALSFRS-R score, with serum Mg significantly influencing the course of the disease. Notably, low serum Mg levels were associated with extended survival times in patients with sALS.  Conclusion  Serum levels of Ca and Mg play critical roles in the progression of sALS, and a reduced serum Mg level is related to an extended survival time.

Liang Zhang, Qian Han, Meiru Bao, Ying Wu
2025, 38(3): 341-350. doi: 10.3967/bes2024.175
  Objective   To evaluate the impact of endometrial polyps (EP) on postoperative pregnancy outcomes in infertile women with endometriosis (EMs).   Methods   PubMed, Embase, The Cochrane Library, CNKI, VIP, SinoMed, and WanFang Data databases were searched to include clinical studies on the effect of EP on pregnancy outcomes in patients with EMs, published before August 31, 2020. A meta-analysis was performed using Rev Man 5.3 software after two investigators independently screened the literature, extracted information, and evaluated the risk of bias of the included studies.   Results   The meta-analysis included ten studies (651 and 1,040 in the combined EP and uncomplicated EP groups, respectively). The spontaneous pregnancy rate, clinical pregnancy rate, and live birth rate were significantly lower in the group with combined EPs than in the group without combined EPs [Odd’s ratio (OR) = 0.63, 95% confidence interval (CI): 0.50–0.80, P = 0.0001; OR = 0.63, 95% CI: 0.48–0.84, P = 0.001; OR = 0.63, 95% CI: 0.42–0.96, P = 0.03], and the rate of embryonic abortion was significantly higher than that in the uncomplicated EP group [OR = 3.10, 95% CI: 1.52–6.32, P = 0.002].  Conclusion   EP may adversely affect pregnancy outcomes in patients with infertility and EMs. Even after surgical treatment, EP can still reduce natural pregnancy, clinical pregnancy, and live birth rates in infertile women with EMs and increase the risk of embryo arrest in these women.

LI Min, SUN Feng, PIAO Jian Hua, YANG Xiao Guang
2014, 27(8): 606-613. doi: 10.3967/bes2014.093
Objective The goal of this study was to analyze protein requirements in healthy adults through a meta-analysis of nitrogen balance studies.
Methods A comprehensive search for nitrogen balance studies of healthy adults published up to October 2012 was performed, each study were reviewed, and data were abstracted. The studies were first evaluated for heterogeneity. The average protein requirements were analyzed by using the individual data of each included studies. Study site climate, age, sex, and dietary protein source were compared.
Results Data for 348 subjects were gathered from 28 nitrogen balance studies. The natural logarithm of requirement for 348 individuals had a normal distribution with a mean of 4.66. The estimated average requirement was the exponentiation of the mean of the log requirement, 105.64 mg N/kg·d. No significant differences between adult age, source of dietary protein were observed. But there was significant difference between sex and the climate of the study site (P<0.05).
Conclusion The estimated average requirement and recommended nutrient intake of the healthy adult population was 105.64 mg N/kg·d (0.66 g high quality protein/kg·d) and 132.05 mg N/kg·d (0.83 g high quality protein/kg·d), respectively.

Objective To detect Japanese encephalitis virus (JEV) rapidly and distinguish its genotypes, a TaqMan-based reverse transcriptase quantitative polymerase chain reaction (RT-PCR) detection system was developed. Methods By aligning the full-length sequences of JEV (G1-G5), six sets of highly specific TaqMan real-time RT-PCR primers and probes were designed based on the highly conserved NS1, NS2, and M genes of JEV, which included one set for non-specific JEV detection and five sets for the detection of specific JEV genotypes. Twenty batches of mosquito samples were used to evaluate our quantitative PCR assay. Results With the specific assay, no other flavivirus were detected. The lower limits of detection of the system were 1 pfu/mL for JEV titers and 100 RNA copies/μL. The coefficients of variation of this real-time RT-PCR were all < 2.8%. The amplification efficiency of this method was between 90% and 103%. Conclusion A TaqMan real-time RT-PCR detection system was successfully established to detect and differentiate all five JEV genotypes.
