BACKGROUND:Myocardial hypertrophy often leads to severe cardiovascular diseases and is difficult to diagnose due to its early stages being hard to detect.Circulating inflammatory proteins have been found to be significantly associated with cardiovascular diseases,yet the specific mechanisms linking them to myocardial hypertrophy remain unclear.OBJECTIVE:To investigate the relationship between circulating proteins and myocardial hypertrophy using multiple Mendelian randomization approaches.METHODS:Utilizing data from 91 circulating inflammatory proteins in the GWAS Catalog database and the latest myocardial hypertrophy data from the R11 FinnGen database,we employed bidirectional two-sample Mendelian randomization,multivariate Mendelian randomization,and Genome-Wide Association Studies co-localization to investigate the causal relationship between circulating inflammatory proteins and myocardial hypertrophy.The accuracy of the results was verified through sensitivity tests including MR-PRESSO,Cochran's Q test,MR-Egger intercept assessment,leave-one-out analysis,and funnel plot analysis.RESULTS AND CONCLUSION:In the results of two-sample Mendelian randomization,the primary method used for evaluation was the Inverse Variance Weighting(IVW)approach.It was found that the level of T-cell surface glycoprotein CD6 isoform(IVW:P=0.046,OR=0.74,95%Cl:0.66-1.00),level of slit chemokine(IVW:P=2.1×10-2,OR=0.74,95%CI:0.556-0.95),level of Delta and Notch-like epidermal growth factor-related receptor(IVW:P=3.7×10-4,OR=0.66,95%CI:0.49-0.87),level of interleukin-2(IVW:P=3.8×103,OR=0.667,95%CI:0.50-0.88),and sulfotransferase 1A1(IVW:P=1.42×102,OR=0.80,95%CI:0.67-0.96)had a unidirectional causal effect on cardiac hypertrophy.(2)Among the findings in multivariate Mendelian randomization,the levels of the CD6 isoform of T-cell surface glycoprotein(IVW:P=1.39×102,OR=0.81,95%CI:0.69-0.96)and the levels of Delta and Notch-like epidermal growth factor-related receptor(IVW:P=3.7×10-2,OR=0.73,95%CI:0.55-0.98)were positive,indicating that the results remained significant after excluding the effects of other circulating inflammatory proteins that had an impact on myocardial hypertrophy.(3)In colocalization,T-cell surface glycoprotein CD6 isoform levels had H3+H4=0.96,with the most significant single nucleotide polymorphism being rs59570070,suggesting an intrinsic link between T-cell surface glycoprotein CD6 isoform levels and myocardial hypertrophy.(4)Sensitivity results showed no abnormalities,indicating no heterogeneity or pleiotropic effects influencing the results.(5)These results verified that T cell surface glycoprotein CD6 isoforms,Slit chemokine,Delta and Notch-like epidermal growth factor-related receptors,interleukin-2,and sulfotransferase 1A1 had a unidirectional causal effect on myocardial hypertrophy.T cell surface glycoprotein CD6 isoforms and Delta and Notch-like epidermal growth factor-related receptors had the deepest impact,suggesting that there may be related pathways between T cell surface glycoprotein CD6 isoforms and myocardial hypertrophy.Mendelian randomization studies require large amounts of clinical data and therefore often use European samples from international databases for analysis.Since this analytical method has significant advantages in causal inference,precision medicine,and cross-population validation,its research results still hold great significance for the medical development in China.As Mendelian randomization research deepens,it also promotes the collection and analysis of clinical data in China to some extent.In the future,we can further analyze key protein mechanisms,combine multiomics and clinical validation,develop an inflammatory marker monitoring system and novel anti-inflammatory therapies,thereby promoting the prevention and control of cardiovascular diseases and the development of personalized medicine.

Objective:
To analyze the current burden of autism spectrum disorder (ASD) among children and adolescents in China and globally, and to predict the disease burden from 2024 to 2035, providing a scientific basis for formulating relevant public health policies and intervention measures.
Methods:
Based on the Global Burden of Disease (GBD) database in 2023, the Joinpoint regression model was used to analyze the changing trends of the disease burden of ASD among children and adolescents in China and globally from 1990 to 2023, and the average annual percent change (AAPC) was calculated. An autoregressive integrated moving average (ARIMA) model was constructed to predict the disease burden trends of ASD among children and adolescents in China and globally from 2024 to 2035.
Results:
The prevalence and disability adjusted life years (DALYs) rate of ASD among children and adolescents in China increased from 452.69/100 000 and 86.67/100 000 in 1990 to 762.84/100 000 and 148.52/ 100 000 in 2023(AAPC=1.60%, 1.65%, both P <0.01). The prevalence and DALYs rate of ASD among children and adolescents globally increased from 648.49/100 000 and 123.47/100 000 to 862.44/100 000 and 167.16/100 000(AAPC=0.87%, 0.93%, both P <0.01). In 2023, the highest ASD prevalence and DALY rates occurred in children under 5 years old, with China reporting 848.14/100 000 and 166.69/100 000, both below the global averages of 928.80/100 000 and 181.34/100 000. Projections indicated that by 2035, the ASD prevalence and DALY rates in China would rise to 906.83/100 000 and 168.71/100 000, still below the global averages of 938.04/100 000 and 184.49/100 000.
Conclusion
The disease burden of ASD among children and adolescents in China and globally has generally increased from 1990 to 2023, with a higher risk of disease at younger ages.

Background: Salvia miltiorrhiza Bunge, commonly known as “Danshen” in China due to the distinctive red color of its roots, is one of the most widely used traditional Chinese medicines. It is cultivated in various regions across China, and environmental differences among these regions can affect the secondary metabolites of plants, thereby influencing the quality of S. miltiorrhiza. In recent years, increasing demand for S. miltiorrhiza has exacerbated the problem of origin fraud. Therefore, ensuring the authenticity of its geographical origin is crucial for the sustainable development of the industry. Objective: The red coloration of S. miltiorrhiza is closely associated with the content of its primary active compounds, particularly tanshinones. Therefore, both its internal chemical composition and external color characteristics serve as key indicators for quality assessment. This study utilized hyperspectral imaging technology to evaluate its potential in classifying the geographical origin of S. miltiorrhiza. Methods: Spectral data reflecting the internal chemical properties of S. miltiorrhiza were integrated with color information representing its external features through 3 levels of data fusion. These fused datasets were then combined with deep learning algorithms to achieve accurate origin classification. Results: The results demonstrated that the Transformer model combined with soft-voting decision-level fusion achieved the highest classification accuracy of 98.72% by integrating image color and short-wave infrared spectral data. Conclusion: This study demonstrates that integrating hyperspectral imaging spectral data with color information provides a reliable and innovative approach for verifying the authenticity and traceability of S. miltiorrhiza.

Objective To explore the effects of sialic acid intervention during pregnancy and the lactational period on the intestinal function of autism model rats.Methods Thirty SPF-grade adult male and female Wistar rats were mated.The successfully pregnant rats were randomly assigned to a valproate-induced model(VPA)group,a high-dose sialic acid(SAH)group,a medium-dose sialic acid(SAM)group,a low-dose sialic acid(SAL)group,and a control(CON)group(n=6 per group)and were housed individually in single cages.On the 12.5th day of pregnancy(E12.5),rats in the VPA and SA intervention groups were given a single intraperitoneal injection of 600 mg/kg sodium valproate(VPA),while the pregnant rats in the CON group were given an equal amount of normal saline.The SA intervention period was from E12.5 to the 21st day after parturition.Feces of offspring rats in each group were collected.The diversity and structure of the gut microbiota were detected by 16S rRNA sequencing.The intestinal transit speed in each group was detected by intragastric administration of carmine.The levels of intestinal-related neurotransmitters(substance P,enkephalin,5-hydroxytryptamine,vasoactive intestinal peptide,and glutamate,gamma-aminobutyric acid)in the blood of rats in each group were detected by ELISA.Results High-dose SA intervention did not affect the diversity of the gut microbiota in the VPA-induced autism model rats,but it changed the structure of the gut microbiota and increased the abundance levels of Prevotella_NK3B31 group,Prevotella,Prevotella spp.,Alloprevotella,Lachnospira,Ruminococcus,and Bacteroides(P<0.05).High-dose SA also promoted the intestinal transit speed,and increased the levels of vasoactive intestinal peptide,5-hydroxytryptamine,and gamma-aminobutyric acid in serum.Conclusions SA intervention during pregnancy and the lactational period affects the intestinal transit speed of VPA-induced autism model rats,changes the structure of the gut microbiome,and increases the levels of vasoactive intestinal peptide,5-hydroxytryptamine,and gamma-aminobutyric acid.

Objective:To systematically and comprehensively retrieve studies on urethra care for patients with urinary catheter at home and abroad, so as to provide a reference for removing low-value care measures in the future.Methods:Arksey and O'?Malley scoping review method was used to systematically search the China National Knowledge Infrastructure, China Biology Medicine disc, WanFang Data, VIP, PubMed, Cochrane Library, CINAHL, Embase, and Web of Science. The search period was from database establishment to January 1, 2024. Literature was screened based on inclusion and exclusion criteria, and catheter care site, disinfection/cleaner type, frequency, institutional norms, and determinants were independently extracted by two researchers, where determinants were framed based on the theoretical domains framework.Results:A total of 21 papers were included. Urethra low-value care measures were reflected in the selection of nursing solutions that differed significantly from guideline recommendations and were inconsistently standardized across hospitals. Thirteen strategies were proposed to remove urethra low-value care measures. Factors that influenced the removal of low-value care behaviors included knowledge, reinforcement, environment and resources, social influences, personal roles and identities, outcome beliefs and memories, and attention and decision-making processes.Conclusions:Future researchers should further refine the evidence on urethra care and develop contextualized care for complex, multilevel healthcare settings to achieve continuous improvement and high quality care at low cost.
