BACKGROUND:
Congenital heart disease (CHD) is a leading cause of birth defect-related mortality. However, more recent CHD mortality data for China are lacking. Additionally, limited studies have evaluated sex, rural-urban, and region-specific disparities of CHD mortality in China.
METHODS:
We designed a population-based study using data from the Dataset of National Mortality Surveillance in China between 2008 and 2021. We calculated age-adjusted CHD mortality using the sixth census data of China in 2010 as the standard population. We assessed the temporal trends in CHD mortality by age, sex, area, and region from 2008 to 2021 using the joinpoint regression model.
RESULTS:
From 2008 to 2021, 33,534 deaths were attributed to CHD. The period witnessed a two-fold decrease in the age-adjusted CHD mortality from 1.61 to 0.76 per 100,000 persons (average annual percent change [AAPC] = -5.90%). Females tended to have lower age-adjusted CHD mortality than males, but with a similar decline rate from 2008 to 2021 (females: AAPC = -6.15%; males: AAPC = -5.84%). Similar AAPC values were observed among people living in urban (AAPC = -6.64%) and rural (AAPC = -6.12%) areas. Eastern regions experienced a more pronounced decrease in the age-adjusted CHD mortality (AAPC = -7.86%) than central (AAPC = -5.83%) and western regions (AAPC = -3.71%) between 2008 and 2021. Approximately half of the deaths (46.19%) due to CHD occurred during infancy. The CHD mortality rates in 2021 were lower than those in 2008 for people aged 0-39 years, with the largest decrease observed among children aged 1-4 years (AAPC = -8.26%), followed by infants (AAPC = -7.01%).
CONCLUSIONS
CHD mortality in China has dramatically decreased from 2008 to 2021. The slower decrease in CHD mortality in the central and western regions than in the eastern regions suggested that public health policymakers should pay more attention to health resources and health education for central and western regions.

Palmitoylation, an essential covalent attachment of a fatty acid (usually C16 palmitate) to cysteine residues within proteins, is crucial for regulating protein functionality and enzymatic activities. This lipid modification facilitates the anchoring of proteins to cellular membranes, dictating their subcellular distribution and influencing protein transport dynamics and intracellular positioning. Additionally, it plays a role in regulating protein degradation through the ubiquitin-proteasome system. Palmitoylation is implicated in the pathogenesis and progression of cardiovascular diseases by modulating substrates and prompting additional post-translational modifications, as well as by interacting with other molecular alterations. Moreover, an intervention strategy focusing on palmitoylation processes is anticipated to offer novel therapeutic avenues for cardiovascular pathologies and address extant challenges in clinical settings. This review consolidates current research on the role and importance of palmitoylation in cardiovascular diseases by exploring its regulatory functions, the catalyzing enzymes, and the involved substrates. It highlights recent discoveries connecting palmitoylation-targeted therapies to cardiovascular health and examines potential approaches and future challenges in cardiovascular treatment.

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.

ObjectiveTo explore the mechanism of Buzhong Yiqitang in ameliorating inflammatory injury in autoimmune thyroiditis (AIT) mice based on the Toll-like receptor 4(TLR4)/nuclear transcription factor-kappa B(NF-κB)/absent in melanoma 2(AIM2)inflammasome signaling pathway. MethodThe 120 genetically susceptible 8-week-old NOD.H-2h4 mice were selected and randomly divided into control group, model group, low, medium and high dose groups of Buzhong Yiqitang (4.78, 9.56, 19.12 g·kg-1), and western medicine group (selenium yeast tablets, 3.033×10-5 g·kg-1). The AIT model mice in each group drank ad libitum 0.05% sodium iodide aqueous solution for 8 weeks to establish the AIT model, and the control group drank ad libitum distilled water. Eight weeks later, the mice in each dosing group were divided into groups and gavage. The swelling of thyroid tissue was observed with the naked eye, and the weight of spleen was weighed. The content of serum inflammatory factors interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) was measured by enzyme-linked immunosorbent assay (ELISA), and Real-time PCR was used to detect the expression of HMGB1, TLR4, AIM2, NF-κB p65,apoptosis-associated speck-like protein(ASC),cysteinyl aspartate-specific protease-1(Caspase-1), IL-1β mRNA. Western blot was used to detect the expression of high motility group protein 1 (HMGB1), TLR4, AIM2, NF-κB p65, phosphorylation(p)-NF-κB p65, ASC, Caspase-1, and IL-1β proteins in thyroid tissue, and immunofluorescence staining was used to observe the protein expression of HMGB1, AIM2, and NF-κB p65 in thyroid tissue of mice. ResultCompared with the control group, the thyroid tissue of mice in the model group was significantly swollen, the spleen quality was significantly increased, and the expression of HMGB1, TLR4, NF-κB p65, AIM2, ASC, Caspase-1, IL-1β in thyroid tissue was significantly increased (P<0.01). Compared with the model group, the swelling of thyroid tissue in mice in each dose group of Buzhong Yiqitang was improved, the quality of spleen was significantly reduced, and the expression of HMGB1, TLR4, AIM2, NF-κB p65, p-NF-κB p65, ASC, Caspase-1, IL-1β in thyroid tissue was significantly reduced (P<0.05, P<0.01). ConclusionBuzhong Yiqitang can effectively improve the inflammatory injury of AIT, and regulating the abnormal activation of the TLR4/NF-κB/AIM2 inflammasome signal pathway may be one of its intervention mechanisms.
