Objective: To analyze the prevalence trends of different types of elevated blood pressure and their association with nutritional status among primary and secondary school students in Inner Mongolia from 2019 to 2024, providing references for targeted prevention strategies. Methods: From September 2019 to 2024, a stratified random cluster sampling method was used to select 12 primary and secondary schools from each league city in Inner Mongolia Autonomous Region. A total of 177 108, 137 758, 190 182, 180 084 , 188 056, 180 351 primary and secondary school students (excluding grades one to three of primary school) were included for physical examination. The correlation between their nutritional status and high blood pressure was analyzed based on the basic situation of 129 821 primary and secondary school students who completed a questionnaire survey at the same time in 2024. Statistical analysis was conducted using a Chi-square test and multiple Logistic regression model. Results: From 2019 to 2024, the detection rates of elevated blood pressure were 13.60%, 13.68%, 17.60%, 17.24%, 14.77% and 15.96%, respectively. The rates for isolated systolic hypertension were 4.24%, 5.83%, 7.26%, 7.19%, 6.24% and 6.93%; isolated diastolic hypertension rates were 6.38%, 4.99%, 6.23 %, 6.41%, 5.39% and 5.66%; and combined systolic and diastolic hypertension rates were 2.97%, 2.86%, 4.11%, 3.65%, 3.14 % and 3.36%. Multivariate Logistic regression analysis showed that girls, junior high school, senior high school, overweight, and obesity were positively associated with elevated blood pressure risk ( OR =1.27, 1.25, 1.32, 1.66, 3.07, all P <0.05); conversely, county residence, Mongolian ethnicity, and other ethnicities showed negative associations ( OR =0.90, 0.93, 0.90, all P <0.05). Conclusions Overweight and obesity among children and adolescents are closely related to various types of elevated blood pressure. Prevention strategies should prioritize effectively controlling weight issues among children and adolescents, thereby effectively reducing the incidence of elevated blood pressure.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

BACKGROUND: Most studies have evaluated disability-adjusted life years (DALYs) of colorectal cancer (CRC) patients based on a set of generic disability weights (DWs). This study aimed to apply local CRC-stage-specific DWs to estimate the burden of DALYs for CRC (CRC-DALYs) in populations in China and consider the influence of local screening coverage of CRC. METHODS: A prevalence-based model was constructed using data from various sources. Years lived with disability (YLDs) were estimated mainly via cumulative prevalence data (based on CRC incidence rates, population numbers, and survival rates), stage-specific proportions of CRC, and DWs of the local population. Years of life lost (YLLs) were calculated based on the CRC mortality rates and standard life expectancies. CRC incidence and mortality rates for the years 2020, 2025, and 2030 were estimated by joinpoint regression, and the corresponding DALYs were predicted. The main assumption was made for CRC screening coverage. Sensitivity analyses were used to assess the impact of population, DWs, and coverage. RESULTS: In 2017, among the Chinese population, the estimated number of CRC-DALYs was 4,303,314 (11.9% for YLDs). If CRC screening coverage rate in China (2.3%) remains unchanged, the overall DALYs in 2030 are predicted to increase by 37.2% (45.1% of those aged ≥65 years). More optimistically, the DALYs would then decrease by 0.7% in 2030 (from 5,902,454 to 5,860,200) if the coverage could be increased to 25.0%. A sensitivity analysis revealed that using local DWs would change the base-case values by 5.7%. CONCLUSIONS The estimated CRC-DALYs in China using population-specific DWs were considerably lower (with a higher percentage of YLDs) than the global burden of disease (GBD) estimates (5,865,004, of 4.6% for YLDs), suggesting the impact extent of applying local parameters. Sustainable scale-up CRC screening needs to be in place to moderate the growth trend of CRC-DALYs in China.

Objective:To understand the current and integrated disease burden and economic burden caused by breast cancer in females in China.Methods:Based on six updated data sources, including the series of Chinese Cancer Registry Annual Report, China Death Cause Surveillance Datasets, China Health Statistical Yearbook, GLOBOCAN, Cancer Incidence in Five Continents, Global Burden of Disease Study (GBD), the information about incidence, mortality and disability adjusted life years (DALY) of breast cancer were extracted for the analysis on the current incidence and time trend of breast cancer and predicted disease burden of breast cancer in females in China. Software Joinpoint was used for time trend analysis. The data of economic burden were systematically updated and analyzed by literature review.Results:1) GLOBOCAN 2022 estimated that the age-standardized incidence rate (ASIR) age-standardized mortality rate (ASMR) and one- year prevalence rate of breast cancer in females were 33.0/100 000, 6.1/100 000 and 40.1/100 000, respectively, in China in 2022. According to Chinese Cancer Registry Annual Report, the ASIR and ASMR were 28.4/100 000 and 5.8/100 000, respectively, in 2018. The China Death Cause Surveillance Datasets showed that the ASMR was 4.5/100 000 in 2021, and the urban to rural area mortality ratio was 1.2∶1. GBD reported that the DALYs of breast cancer were 2.921 million in China in 2021, accounting for 14.4% of the global total. 2) Chinese Cancer Registry Annual Report data showed that the ASIR and ASMR of breast cancer decreased by 2.1% and 11.4%, respectively, in China from 2009 to 2018, while increased by 43.9% and 8.2% in rural area, respectively. The Joinpoint analysis showed that the average annual percentage change (AAPC) of ASIR and ASMR in China were -0.2% ( P>0.05) and -1.6% ( P<0.05). The AAPC of ASIR and ASMR in rural area were 3.9% ( P<0.05) and 0.6% ( P>0.05), and -0.3% ( P>0.05) and -1.2% ( P<0.05) in urban area, respectively. China Health Statistical Yearbook data showed that the urban ASMR decreased by 12.3% from 2014 to 2021 with AAPC of -2.6% ( P<0.05). 3) The GLOBOCAN 2022 predicted that, the breast cancer case count and death count in China would be 387 776 and 111 133 by 2050, an increase of 8.6% and 48.2%, respectively, compared with 2022, the increases would be more obvious in people over 65 years old, an increase of 80.8% and 124.9%, respectively. 4) Thirteen individual- based studies reported that the median medical expenditure per patient ( M=21 000 to 39 000 Yuan) and length of hospital stay ( M=11.0 to 30.5 days) for breast cancer treatment decreased from 2010 to 2019, while the average medical expenditure per visit ( M=9 000 to 23 000 Yuan) showed an upward trend. There was only one national-level analysis, which showed that the treatment cost of breast cancer was 25.24 billion Yuan in China in 2018, accounting for 6.4% of the total cancer treatment cost. Conclusions:According to the above updated multi-source data, the incidence and mortality of female breast cancer in China were stable in the past ten years, but the increasing trend in rural area should be noted. The direct medical expenditure of breast cancer treatment per case might decrease, but the population-level economic burden would remain heavy due to population aging.

Obesity is an independent factor affecting the development, progression and prognosis of breast cancer. Adipokines and their receptors play an important role in the development and progression of breast cancer. Leptin is one of the important adipokines. After binding with leptin receptors, leptin not only plays an important role in metabolism, but also promotes tumor cell proliferation, migration and angiogenesis, inhibits tumor cell apoptosis and other biological effects. Besides, it is related to the outcome of neoadjuvant chemotherapy and treatment resistance. This paper reviews the possible molecular mechanism, expression characteristics, treatment and relationship with prognosis of leptin and leptin receptor in breast cancer.

Objective:To investigate the associations of serum amyloid A (SAA) with the overall burden of cerebral small vessel disease (CSVD) and early neurological deterioration (END) in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to the Department of Neurology, Baise People's Hospital from August 2021 to August 2023 were included retrospectively. END was defined as an increase of ≥2 in the National Institutes of Health Stroke Scale (NIHSS) score within 72 hours of onset compared to the admission score. The baseline data of patients with different CSVD burden group, as well as END and non-END groups were compared. Multivariate logistic regression analysis was used to determine the independent correlation factors for the overall burden of CSVD and END. Results:A total of 131 patients with AIS were enrolled, including 78 males (59.54%), aged 63.80±7.34 years. Sixteen patients (12.2%) were in the CSVD overall burden 0-point group, 58 (44.3%) in the 1-point group, 29 (22.1%) in the 2-point group, 22 (16.8%) in the 3-point, and 6 (4.6%) in the 4-point group; and 52 (39.7%) experienced END. There were significant differences in age, diabetes, smoking, drinking, NIHSS score at admission, total burden of CSVD, previous stroke or transient ischemic attack history, homocysteine, fasting blood glucose, uric acid and SAA between the END group and the non-END group (all P<0.05). Multivariate logistic regression analysis showed that SAA was an independent risk factor for END (odds ratio 4.703, 95% confidence interval 2.492-8.875; P<0.001). There was a significant difference in SAA among different CSVD burden groups ( P<0.001), and SAA increased with the increase of CSVD burden score. Ordinal multivariate logistic regression analysis showed that SAA was independently correlated with the overall burden of CSVD (odds ratio 4.576, 95% confidence interval 2.542-8.239; P<0.001). Conclusion:SAA is associated with the overall burden of CSVD and END in patients with AIS.
