Objective To systematically analyze the characteristics of the disease burden of hypertensive heart disease (HHD) in the elderly (≥60 years) globally and in China from 1990 to 2021, and to predict its future trends from 2022 to 2040, with the aim of providing data support for optimizing comprehensive prevention and control strategies for HHD. Methods Based on the Global Burden of Disease (GBD) 2021 database, the number of prevalent cases and disability-adjusted life years (DALYs) of HHD in the elderly were extracted for the world, China, and five regions categorized by sociodemographic index (SDI). Joinpoint regression was used to analyze the temporal trends of age-standardized prevalence rate and age-standardized DALYs rate of HHD in the elderly. A three-factor decomposition method was applied to evaluate the relative contributions of aging, population growth, and epidemiological changes to the variations in the elderly HHD burden. Additionally, a Bayesian age-period-cohort model was used to predict the elderly HHD burden from 2022 to 2040. Results In 2021, the number of prevalent elderly HHD cases reached 10 283 000 globally and 3 412 400 in China, representing increases of 179.20% and 159.20% respectively, compared with 1990. The DALYs of elderly HHD were 18 812 700 person-years globally and 4 731 400 person-years in China, rising by 76.08% and 29.45% respectively from 1990. Meanwhile, the growth rates of the number of prevalent cases and DALYs of elderly HHD varied across different SDI regions. From 1990 to 2021, the age-standardized prevalence rate of elderly HHD in China, as well as the age-standardized DALYs rate of elderly HHD both globally and in China, showed significant downward trends (all average annual percentage changes<0, all P<0.001). In 2021, the 70-74 years age group accounted for the highest proportion of prevalent cases and DALYs of elderly HHD, both globally and in China. Decomposition analysis revealed that population growth was the dominant factor driving the increase in the elderly HHD burden across all regions. The prediction model results indicated that the number of prevalent cases and DALYs of elderly HHD would continue to rise globally and in China from 2022 to 2040, with the growth rate of the elderly HHD burden in China between 2021 and 2040 expected to exceed the global average. Conclusion Over the past 32 years, although the age-standardized disease rates of elderly HHD have mainly shown a downward trend globally and in China, the absolute number of the disease burden has increased substantially. The projection model indicates a continued upward trajectory, with the growth rate in China higher than the global average. Therefore, there is an urgent need to implement precise prevention and control strategies to effectively mitigate the disease burden of elderly HHD.

Objective: To evaluate the practical effectiveness of confidential unit exclusion (CUE) in ensuring blood safety in Zhengzhou, analyze its application characteristics and existing problems, and provide a basis for optimizing blood safety management strategies. Methods: A retrospective analysis was conducted on CUE data handled by Henan Red Cross Blood Center from January 2019 to December 2024. Parameters such as the number of cases, demographic characteristics, reasons for exclusion, and time of report were statistically analyzed and compared with those of non-CUE. Results: From 2019 to 2024, the CUE reporting rate in Zhengzhou was 0.002 6% (40/1 547 666). CUE donors were predominantly male (65.00%, 26/40), aged 18-34 years (47.50%, 19/40), had college degree orabove (50.00%, 20/40), and were employees of enterprises or public institutions (32.50%, 13/40). Among the 40 CUE blood units, only one was reactive for anti-TP, while all others were qualified. The main reasons for CUE were recent vaccination (32.50%, 13/40), medical conditions unsuitable for donation (27.50%, 11/40), and high-risk sexual behavior (17.50%, 7/40). A total of 70.00% of reports occurred within 24 hours after donation, during which none of the corresponding blood units had been released; all units reported after more than 7 days had already been issued for clinical use, with no adverse transfusion reactions reported upon follow-up. Conclusion: The confidential unit exclusion program has played an active role in establishing a supplementary information feedback channel for blood donors. The procedure can be optimized by strengthening interactive communication and confirmation before donation, improving the accuracy of donors' self-assessment, and expanding convenient and rapid information-based reporting channels.

OBJECTIVE: To analyze the clinical characteristics, treatment, and prognosis of seven pediatric patients with Acute myeloid leukemia (AML) positive for the t(16;21)(p11;q22) FUS::ERG fusion gene. METHODS: A retrospective analysis was carried out on the clinical data, treatment, and prognosis of seven AML patients with t(16;21)(p11;q22) FUS::ERG fusion gene admitted to Henan Children's Hospital between June 2015 and November 2024. Relevant literature was also reviewed. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: 2024-102-001). RESULTS: Among 297 pediatric patients with AML, 7 cases (2.36%) were positive for the t(16;21)(p11;q22) FUS::ERG fusion gene, including 3 males and 4 females, with a median age of 11 years (range: 3 ~ 12 years). According to the FAB classification, these included 1 case of M2, 3 cases of M5, and 3 cases of AML-not otherwise specified (non-M3). All 7 patients were found to harbor the t(16;21)(p11;q22) translocation, with 3 cases showing additional chromosomal abnormalities. Immunophenotyping revealed universal expression of CD13, CD33, CD34, and CD117, with partial expression of CD56, CD4, CD64, CD123, CD15, CD38, CD11b, HLA-DR, cMPO, and CD16. One patient achieved complete remission (CR) after the first course of DAE (cytarabine + daunorubicin + etoposide) induction chemotherapy but relapsed and discontinued the treatment. Six patients received DAH (cytarabine + daunorubicin + homoharringtonine) induction therapy, of whom 2 achieved CR after two courses and underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT), resulting in an overall CR rate of 42.86%. Five children did not receive allo-HSCT and had a median overall survival of 9 months (range: 6 ~ 18 months). Two children who underwent transplantation achieved bone marrow morphological and molecular biological relapse at 6 and 9 months post-transplantation, respectively. After receiving combined chemotherapy and donor lymphocyte infusion, one child failed to achieve remission and died at 22 months post-transplantation, while the other has been followed up to date with positive fusion gene status. Their overall survival was 25 months and 30 months, respectively. CONCLUSION The t(16;21)(p11;q22) FUS::ERG fusion gene is rare in pediatric AML and associated with poor prognosis. Allo-HSCT may mitigate the adverse prognostic impact of the FUS::ERG fusion gene and contribute to prolonged survival.

arcopenia is a systemic skeletal muscle disorder characterized by a decrease in skeletal muscle mass and progressive decline in function， with multiple signaling pathways involved in its occurrence and development. Among them， the AMP-activated protein kinase （AMPK） signaling pathway， as a key pathway regulating cellular energy homeostasis， plays an important role in the regulation of skeletal muscle metabolism and functional maintenance by improving abnormalities in glucose and lipid metabolism， balancing skeletal muscle protein synthesis and degradation， improving mitochondrial function， promoting autophagy， and inhibiting inflammatory responses and oxidative stress. This article reviews the research progress on how various traditional Chinese medicine （TCM） monomers， including polyphenols， flavonoids， and terpenoids； various traditional Chinese medicine extracts， such as those from Lycium barbarum ， Asini Corii Colla， and Panax quinquefolium ， and TCM compounds， such as Guiqi zhuangjin decoction， Jianpi qiangji granules， and Qigu capsules， intervene in sarcopenia by regulating the AMPK signaling pathway to promote muscle protein synthesis， inhibit protein degradation， improve mitochondrial function， and alleviate inflammation and oxidative stress. Additionally， their molecular mechanisms are explored. The aim is to deeply elucidate the basis of TCM in the prevention and treatment of sarcopenia and to provide theoretical support for the development of related innovative drugs.

Objective Based on data from the Global Burden of Disease Study 2023 (GBD 2023), this study analyzes the trends in disease burden and years lived with disability (YLD) of bladder cancer in China from 1990 to 2023. Methods Epidemiological data on bladder cancer in China were obtained from the GBD 2023 database.The age-standardized prevalence rate (ASPR), YLD and population attributable fraction (PAF) of risk factors were calculated.Temporal trends were evaluated using the estimated annual percentage change (EAPC), and Joinpoint regression was applied to compute the annual percent change (APC) and average annual percent change (AAPC) for trend analysis. Results Between 1990 and 2023, the number of bladder cancer patients requiring rehabilitation services increased from 213 568 cases to 587 191 cases, representing a 175.0% increase.The YLD rose from 22 158 to 56 620, marking a 155.6% growth.The ASPR increased from 22.6/100 000 to 25.7/100 000 (EAPC=0.06), indicating a stable trend.The age-standardized YLD rate (ASYR) remained at 2.5/100 000 (EAPC=-0.32), indicating a downward trend.Notably, gender disparities in disease burden were evident, with male patients and YLD being 4.63 times and 4.25 times higher than their female counterparts, respectively.Risk factor analysis showed that smoking and high fasting plasma glucose were the main risk factors for bladder cancer.The ASYR attributable to high fasting plasma glucose showed an increasing trend in males (EAPC=0.13) but a decreasing trend in females (EAPC=-1.41). Conclusion The demand for rehabilitation and disease burden of bladder cancer in China have significantly increased, with particularly heavy burdens among males and the elderly population.It is urgent to formulate targeted interventions, strengthen tobacco control, occupational protection, and weight management, and establish an integrated rehabilitation service system to address the increasingly severe disease burden caused by bladder cancer.

Objective To analyze esophageal cancer burden trends in China from 1990 to 2021, further project the burden from 2022 to 2050. Methods The time trends of standardized incidence, standardized mortality, and standardized disability-adjusted life years (DALYs) rate of esophageal cancer in China from 1990 to 2021 using data from the Global Burden of Disease 2021 were analyzed using the estimated annual percentage change (EAPC). The disease burden of esophageal cancer in China from 2022 to 2050 was predicted using the Bayesian age–period–cohort model combined with sensitivity analysis and model calibration. Results In China, the ASIR of esophageal cancer increased from 17.637 per 10⁵ in 1990 to 22.548 per 10⁵ in 2021 (EAPC=0.55, 95%CI: 0.38–0.71). The ASMR rose from 17.920 per 10⁵ in 1990 to 20.836 per 10⁵ in 2021 (EAPC=0.21, 95%CI: 0.02–0.39). The age-standardized DALYs decreased from 497.437 per 10⁵ in 1990 to 484.884 per 10⁵ in 2021 (EAPC=−0.39, 95%CI: from −0.59 to −0.2). Among individuals aged 45 years and above, the proportion of esophageal cancer cases increased from 93.32% in 1990 to 97.56% in 2021, and the proportion of deaths in this age group rose from 90.44% in 1990 to 98.22% in 2021. For individuals aged 40 years and above, the proportion of DALYs attributed to esophageal cancer increased from 95.29% in 1990 to 98.29% in 2021. Among people aged 20 years and above, the incidence rate of esophageal cancer showed a downward trend in all age groups. In particular, the 35–39 year age group exhibited the most significant decline (EAPC=−3.74, 95%CI: from −4.22 to −3.25). Among individuals aged 20 years and above, the 70+ year age group had the smallest decrease in ASMR and age-standardized DALYs. By 2050, the standardized prevalence, standardized incidence, standardized mortality, and standardized DALY rate of esophageal cancer in China were predicted to decrease to 25.1/10⁵, 6.4/10⁵, 14.2/10⁵, and 12.0/10⁵, respectively. Conclusion From 1990 to 2021, the ASIR and ASMR of esophageal cancer in China showed an upward trend, whereas the age-standardized DALY rate exhibited a slow downward trend. Although the incidence of esophageal cancer showed a downward trend across all the age groups from 20 years and above, the overall standardized rate exhibited an upward trend due to factors such as population aging. By 2050, the burden of esophageal cancer in China, including prevalence, incidence, mortality, and DALYs, will decline. The population aged 45 years and above is the core group affected by esophageal cancer and should be prioritized for prevention and control.

OBJECTIVE To investigate the mechanism of Yangfei tongluo formula in delaying airway remodeling in post-infectious bronchiolitis obliterans （PIBO） model rats.METHODS Forty-eight 2-week-old SPF male SD rats were randomly divided into control group （Control group）， PIBO model group （Model group）， Prednisone Acetate tablets+Azithromycin tablets group [positive control group， Prednisone Acetate tablets 0.006 3 g/（kg·d）+Azithromycin tablets 0.031 5 g/（kg·d）]， and high-， medium-， and low-dose Yangfei tongluo formula groups [42.42， 21.21， 10.60 g/（kg·d）]. The PIBO rat model was established by intratracheal instillation of diacetyl. After modeling， rats in each group were administered corresponding drug solution or distilled water by gavage once daily for 21 consecutive days. Hematoxylin-eosin staining was used to evaluate the pathological changes of lung tissue， and Masson staining was used to assess the degree of pulmonary fibrosis. Western blot and real-time quantitative PCR were performed to detect the protein and mRNA expression levels of epithelial-mesenchymal transition （EMT）-related markers [E-cadherin， N-cadherin， α -smooth muscle actin （ α -SMA）， Vimentin] and transcription factors [snail homolog 1（Drosophila）-like 1 protein （Snail1）， zinc finger E-box-binding homeobox protein 1 （ZEB1）， Twist-related protein 1 （Twist1）] in lung tissue. ELISA was used to detect the levels of transforming growth factor-β 1 （TGF-β 1 ） and vascular endothelial growth factor （VEGF） in blood and bronchoalveolar lavage fluid.RESULTS Compared with the Control group， the lung tissues of rats in the Model group showed extensive destruction of alveolar structure and massive inflammatory cell infiltration in the interstitium. The protein and mRNA expression levels of E-cadherin were significantly decreased， while the protein and mRNA expression levels of N-cadherin， Vimentin， α -SMA， Snail1， ZEB1， and Twist1， as well as the collagen-positive area and the levels of TGF-β 1 and VEGF， were significantly increased （ P ＜0.05）. Compared with the Model group， the pathological injury of lung tissue in each administration group was significantly improved， and the above indicators （except collagen-positive area） were significantly reversed （ P ＜0.05）.CONCLUSIONS Yangfei tongluo formula may delay airway remodeling in PIBO by regulating the TGF-β 1 /VEGF-mediated signaling network and inhibiting the activation of EMT-related transcription factors， thereby blocking the EMT process.

ObjectiveTo investigate the effect and mechanism of Shengxian Yixin Granule （升陷益心颗粒， SYG） in treating heart failure with preserved ejection fraction （HFpEF）. MethodsExperiment 1： Forty male C57BL/6 mice were randomly divided into control group， model group， low-dose ［25 mg/（kg·d）］， medium-dose ［50 mg/（kg·d）］， and high-dose ［（75 mg/（kg·d）］ SYG groups， with 8 mice per group. Except for the control group， HFpEF was induced by a high-fat diet combined with Nω-nitro-L-arginine methyl ester in drinking water for 16 weeks. After 10 weeks of modeling， treatment groups received corresponding doses of SYG by gavage， while the control group and model group received equal volume of normal saline， for 6 weeks. After 6 weeks of administration， the body weight， blood pressure including systolic blood pressure （SBP） and diastolic blood pressure （DBP）， and heart weight-to-tibia length ratio （HW/TL） were recorded. Echocardiography was used to evaluate left ventricular ejection fraction （LVEF） and the ratio of early to late diastolic transmitral flow velocity （E/A）. Plasma N-terminal pro-brain natriuretic peptide （NT-proBNP） and C-reactive protein （CRP） levels were measured by ELISA. The expression level of brain natriuretic peptide （BNP） in heart tissue was detected by qRT-PCR. Blood lipid levels， including low-density lipoprotein cholesterol （LDL-C）， triglycerides （TG）， and total cholesterol （TC）， were determined by a biochemical analyzer. Splenic proportions of M1 macrophages， M2 macrophages， T helper 17 （Th17） cells， and regulatory T （Treg） cells were analyzed by flow cytometry. Experiment 2： RAW 264.7 cells were stimulated with lipopolysaccharide （LPS） to establish an M1 macrophage polarization model， and then treated with SYG-containing serum for 24 h. The cells were divided into four groups， including blank serum group， high-dose SYG-containing serum group， LPS group， and LPS plus high-dose SYG-containing serum group. Combined with asignal transducer and activator of transcription 3 （Stat3） inhibitor for 24 h， the cells were divided into a lipopolysaccharide group， a high-dose SYG-containing serum group， an inhibitor group， and high-dose SYG-containing serum plus inhibitor group. The expression levels of inducible nitric oxide synthase （iNOS） and interleukin-1β （IL-1β） in each group were detected by qRT-PCR. The protein levels of iNOS， IL-1β， Stat3， and phosphorylated Stat3 （p-Stat3） were detected by Western Blotting. ResultsExperiment 1： Compared to the control group， the model group showed significantly decreased E/A ratio， and increased cardiac BNP expression， plasma NT-proBNP，HW/TL ratio， body weight， TC， LDL-C， SBP， and DBP， as well as shortened exhaustion distance and exhaustion time （P＜0.05 or P＜0.01）. Compared to the model group， the E/A ratio increased in the low-， medium-， and high-dose SYG groups； cardiac BNP expression decreased in the low- and high-dose groups， and plasma NT-proBNP levels decreased in the high-dose group； the HW/TL ratio and body weight decreased， while exhaustion distance and exhaustion time increased in the medium- and high-dose groups； TG levels decreased in the low- and medium-dose groups， and LDL-C levels decreased in the medium- and high-dose groups； SBP and DBP decreased in the low-， medium-， and high-dose groups （P＜0.05 or P＜0.01）. Compared to the low-dose SYG group， body weight decreased， and both exhaustion distance and exhaustion time increased in the medium- and high-dose groups （P＜0.05 or P＜0.01）. Compared to the medium-dose SYG group， the exhaustion time increased in the high-dose SYG group （P＜0.01）. Experiment 2： In the LPS‑induced M1 macrophage polarization model， compared to the blank serum group， the LPS group showed significantly increased mRNA and protein expression of iNOS and IL‑1β， as well as the p‑Stat3/Stat3 ratio （P＜0.01）. Compared to the LPS group， the high‑dose SYG-containing serum plus LPS group showed significantly decreased mRNA and protein expression of iNOS and IL‑1β， as well as the p‑Stat3/Stat3 ratio （P＜0.05 or P＜0.01）. Compared to the LPS group， the inhibitor group also showed significantly reduced these parameters （P＜0.05 or P＜0.01）. ConclusionSYG can improve cardiac function， ventricular remodeling， exercise capacity， and lipid metabolism in HFpEF mice， while inhibiting inflammatory responses. Its mechanism may be related to the regulation of the Stat3 signaling pathway and inhibition of M1 macrophage polarization.

The recombinant human thyroid-stimulating hormone (rhTSH) can be used for differentiated thyroid cancer (DTC) preparation before ¹³¹I therapy, and follow-up. Since its approval by the American Food and Drug Administration (FDA) in 1998, rhTSH has been clinically used in European countries, the United States, and other countries for nearly 30 years. In April 2024, China’s first independently developed rhTSH agent was approved. Based on clinical experience and evidence from domestic and international studies, an expert consensus on the application of rhTSH has been developed following thorough consultations among experts. The consensus offers evidence-based recommendations to guide the appropriate use of rhTSH in clinical practice.
