ObjectiveTo examine the influences of Shenfu injection on the endogenous metabolic byproducts in the myocardium of the rat model exhibiting chronic heart failure, thus deciphering the therapeutic mechanism of the Qi-reinforcing and Yang-warming method. MethodsSD rats were randomly allocated into a control group and a modeling group. Chronic heart failure with heart-Yang deficiency syndrome in rats was modeled by multi-point subcutaneous injection of isoproterenol, and the rats were fed for 14 days after modeling. The successfully modeled rats were randomized into model, Shenfu injection (6.0 mL·kg-1), and trimetazidine (10 mg·kg-1) groups and treated with corresponding agents for 15 days. The control group and the model group were injected with equal doses of normal saline, and the samples were collected after the intervention was completed. Cardiac color ultrasound was performed. Hematoxylin-eosin (HE) staining was used to observe histopathological morphology, and the serum level of N-terminal pro-brain natriuretic peptide (NT-proBNP) was assessed by enzyme-linked immunosorbent assay (ELISA). The mitochondrial morphological and structural changes of cardiomyocytes were observed by transmission electron microscopy, and the metabolic profiling was carried out by ultra high performance liquid chromatography-quantitative exactive-mass spectrometry (UHPLC-QE-MS). Differential metabolites were screened and identified by orthogonal partial least squares-discriminant analysis (OPLS-DA) and other methods, and then the MetaboAnalyst database was used for further screening. The relevant biological pathways were obtained through pathway enrichment analysis. The receiver operating characteristic (ROC) curve was established to evaluate the diagnostic value of each potential biomarker for myocardial injury and the evaluation value for drug efficacy. ResultsThe results of color ultrasound showed that Shenfu Injection improved the cardiac function indexes of model rats (P<0.05). The results of HE staining showed that Shenfu injection effectively alleviated the pathological phenomena such as myocardial tissue structure disorder and inflammatory cell infiltration in model rats. The results of ELISA showed that Shenfu injection effectively regulated the serum NT-proBNP level in the model rats. Transmission electron microscopy (TEM) showed that Shenfu injection effectively restored the mitochondrial morphological structure. The results of metabolomics showed that the metabolic phenotypes of myocardial samples presented markedly differences between groups. Nine differential metabolites could be significantly reversed in the Shenfu injection group, involving three metabolic pathways: pyruvate metabolism, histidine metabolism, and citric acid cycle (TCA cycle). The results of ROC analysis showed that the area under the curve (AUC) values of all metabolites were between 0.75 and 1.0, indicating that the differential metabolites had high diagnostic accuracy for myocardial injury, and the changes in their expression levels could be used as potential markers for efficacy evaluation. ConclusionShenfu injection significantly alleviated the damage of cardiac function, myocardium, and mitochondrial structure in the rat model of chronic heart failure with heart-Yang deficiency syndrome by ameliorating energy metabolism remodeling. Reinforcing Qi and warming Yang is a key method for treating chronic heart failure with heart-Yang deficiency syndrome.

ObjectiveTo investigate the expression of serum Aldo-keto reductase family 1 member B10 (AKR1B10) in patients with hepatocellular carcinoma (HCC) in northern China, and to provide a new and valuable biomarker for the clinical diagnosis of HCC. MethodsThis study was conducted among 102 patients with HCC, 119 patients with benign liver disease, and 132 patients with other malignant tumors who attended The Affiliated Hospital of Chengde Medical University and 148 healthy individuals who underwent physical examination from May 2020 to May 2024. ELISA and chemiluminescence were used to measure the serum levels of AKR1B10 and alpha-fetoprotein (AFP). The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the Kruskal-Wallis H test was used for comparison between three groups and further comparison between two groups; the chi-square test was used for comparison of categorical data between groups. The area under the ROC curve (AUC) was used to assess diagnostic efficiency. ResultsThe expression level of AKR1B10 was 3 053.79 (1 475.67 — 4 605.86) pg/mL in the HCC group, 1 324.42 (659.68 — 2 023.88) pg/mL in the benign liver disease group, 660.68 (377.56 — 2 087.77) pg/mL in the other malignant tumor group, and 318.30 (82.73 — 478.82) pg/mL in the healthy group, with a significant difference between the four groups (H=240.86, P<0.001), and further comparison between two groups showed that the HCC group had a significantly higher level than the other three groups (all P<0.001). The ROC curve analysis of the HCC group and the other three groups showed that serum AKR1B10 had an optimal cut-off value of 1 584.97 pg/mL in the diagnosis of HCC, with an AUC of 0.86 (95% confidence interval [CI]: 0.82 — 0.90), a sensitivity of 74.3%, and a specificity of 85.2%. Compared with each indicator alone, a combination of AKR1B10 and AFP could improve the sensitivity (81.8%) and specificity (91.4%) of HCC diagnosis. AKR1B10 had an AUC of 0.84 (95%CI: 0.78 — 0.90) in the diagnosis of patients with early- or middle-stage HCC, with a sensitivity of 76.2% and a specificity of 81.2%. AKR1B10 had an AUC of 0.85 (95%CI: 0.77 — 0.92) in the diagnosis of patients with AFP-negative HCC, with a sensitivity of 81.6% and a specificity of 79.9%. ConclusionAKR1B10 is a promising serological marker for the diagnosis of HCC, and a combination of AKR1B10 and AFP can improve the detection rate of HCC patients in northern China, especially those with early- or middle-stage HCC and AFP-negative HCC.

Objective:
To investigate the current status and influencing factors for cognitive frailty among the elderly in community, so as to provide the evidence for early identification and prevention of cognitive frailty among the elderly.
Methods:
Residents aged 60 years and above with local household registration from 11 counties (cities, districts) in Zhejiang Province from 2021 to 2023 were selected as study participants using a multistage random sampling method. Demographic information, lifestyle, and health status were collected through questionnaire surveys. Depressive symptoms were assessed using the Patient Health Questionnaire. Cognitive frailty was evaluated using the FRAIL Scale and the Mini-Mental State Examination. Factors affecting cognitive frailty among the elderly in community were identified using a multivariable logistic regression model.
Results:
A total of 16 613 individuals were surveyed, including 7 465 males (44.93%) and 9 148 females (55.07%). The average age was (70.97±7.29) years. A total of 784 individuals were detected with depressive symptoms, with a detection rate of 4.72%. A total of 724 individuals were detected with cognitive frailty, with a detection rate of 4.36%. Multivariable logistic regression analysis showed that females (OR=1.419, 95%CI: 1.179-1.708), aged ≥70 years (70-<80 years old, OR=1.869, 95%CI: 1.490-2.345; ≥80 years old, OR=5.017, 95%CI: 3.935-6.398), without a spouse (OR=1.495, 95%CI: 1.234-1.810), sedentary (OR=2.420, 95%CI: 1.829-3.202), chronic diseases (1 type, OR=1.456, 95%CI: 1.175-1.804; ≥2 types, OR=1.639, 95%CI: 1.314-2.045), and depressive symptoms (OR=4.191, 95%CI: 3.361-5.225) were associated with a higher risk of cognitive frailty among the elderly in community. Conversely, a lower risk of cognitive frailty was seen among the elderly in community who had primary school or above (primary school, OR=0.512, 95%CI: 0.389-0.676; junior high school or above, OR=0.464, 95%CI: 0.354-0.608), engaged in physical exercise (OR=0.396, 95%CI: 0.291-0.539), and were reported average or good self-rated health status (average, OR=0.641, 95%CI: 0.475-0.866; good, OR=0.150, 95%CI: 0.109-0.208).
Conclusions
The detection rate of cognitive frailty among the elderly in community is relatively low and is influenced by demographic factors such as gender, age, education level, as well as lifestyle like sedentary and physical exercise, and health status. It is recommended to reduce the risk of cognitive frailty among the elderly through multidimensional interventions, including health education, promotion of healthy lifestyles, and enhanced mental health support.

OBJECTIVES:
To investigate the regulatory effect of LINC00837/miR-671-5p/SERPINE2 functional axis on pathological processes of fibroblast-like synovial cells (FLS) in rheumatoid arthritis (RA).
METHODS:
RA-FLS were transfected with a LINC00837 overexpression plasmid (pcDNA3.1-LINC00837), a LINC00837 interference plasmid (siRNA-LINC00837), or their respective negative control plasmids (pcDNA3.1-NC and siRNA-NC). Dual luciferase was used to verify the targeting relationship between LINC00837 and miR-671-5p and between miR-671-5p and SERPINE2. RT-qPCR was used to detect the expression levels of LINC00837, miR-671-5p and SERPINE2 in normal FLS or the transfected cells, whose proliferation and migration abilities were assessed using Edu assay and scratch healing assay and by detecting the expression levels of Ki-67, PCNA, E-cadherin and N-cadherin with Western blotting. The changes in cellular secretion of the inflammatory cytokines (TNF‑α, IL-17, IL-4 and IL-10) were examined using ELISA.
RESULTS:
Dual luciferase reporter gene assay showed that LINC00837 was capable of binding to the 3'-UTR of miR-671-5p, and the latter bound to the 3-UTR of SERPINE2 at specific binding sites between them. Compared with normal FLS, RA-FLS showed significantly increased expressions of LINC00837 and SERPINE2, lowered miR-671-5p expression and enhanced proliferation and migration abilities with increased expressions of pro-inflammatory cytokines and reduced expressions of anti-inflammatory cytokines. Transfection of RA-FLS with pcDNA-LINC00837 further enhanced cell proliferation and migration and the changes in the inflammatory cytokines, while transfection with si-LINC00837 produced the opposite changes.
CONCLUSIONS
RA-FLS have a LINC00837/miR-671-5p/SERPINE2 functional axis, which regulates cell proliferation, migration and secretion of inflammatory factors, and interventions targeting LINC00837 may provide a potential strategy to regulate the pathological processes in RA-FLS.

OBJECTIVE To evaluate the cost-effectiveness of omalizumab in the treatment of severe allergic asthma from the perspective of healthcare providers in China. METHODS Based on the data from an international multicenter study of omalizumab in the treatment of severe allergic asthma, the Markov model was constructed according to the progression of severe allergic asthma, with a cycle of 4 weeks. Long-term health outcomes and costs of omalizumab combined with standard of care(SoC) regimen versus SoC regimen in the treatment of severe allergic asthma were simulated by using quality-adjusted life years (QALYs) and incremental cost-effectiveness ratio(ICER) as output indexes. One-way sensitivity analysis, probabilistic sensitivity analysis, and scenario analysis were performed to test the robustness of the results. RESULTS Compared with the SoC regimen, ICER for the omalizumab combined with SoC regimen was 107 723.05 yuan/QALY, which was less than the willingness-to-pay(WTP) threshold (268 074 yuan/QALY) calculated by three times per capita gross domestic product(GDP) in China in 2023. The one-way sensitivity analysis showed that the baseline serum level of immunoglobulin E had the greatest impact on the robustness of the model. The probabilistic sensitivity analysis showed that the omalizumab+SoC regimen had a 93.00% probability of being cost- effective. The scenario analysis showed that in the real world, the billing method of omalizumab based on specifications rather than actual usage may increase ICER. CONCLUSIONS Compared with the SoC regimen, the combination of omalizumab and SoC regimen for treating severe allergic asthma is cost-effective, with a WTP threshold of three times China’s per capita GDP

OBJECTIVE To evaluate the cost-effectiveness of tislelizumab combined with chemotherapy as first-line treatment for locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma. METHODS The data of RATIONALE-305 study and related literature were used to establish a partitioned survival model from the perspective of China’s health system. The cycle was 3 weeks, the simulation time was set as 10 years, and the discount rate was 5%. The quality-adjusted life years (QALYs) were used as the health outcome indicator to evaluate the cost-effectiveness of tislelizumab combined with chemotherapy versus placebo combined with chemotherapy as first-line treatment for locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma, and one-way sensitivity analysis and probabilistic sensitivity analysis were also conducted. RESULTS The base analysis showed that the patients received more 0.268 QALYs with tislelizumab plus chemotherapy, compared with placebo plus chemotherapy, but the cost increased by 70 404.81 yuan with an incremental cost- effectiveness ratio (ICER) of 262 431.62 yuan/QALY, which was less than three times China’s gross domestic product (GDP) per capita in 2023 as the willingness-to-pay (WTP) threshold (268 074 yuan/QALY). One-way sensitivity analysis showed that the efficacy value of progress free survive and the price of tislelizumab had a greater impact on the ICER value. The results of probability sensitivity analysis showed that when the WTP threshold was 3 times China’s GDP per capita in 2023, the probability of tislelizumab being cost-effective was 53.3%. CONCLUSIONS When the WTP threshold is 3 times China’s GDP per capita in 2023, tislelizumab plus chemotherapy is cost-effective for first-line treatment of locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma, compared with placebo plus chemotherapy.

OBJECTIVE To assess the long-term cost-effectiveness of five glucagon-like peptide-1 receptor agonists (GLP- 1RAs) in the treatment of poorly controlled type 2 diabetes mellitus (T2DM) treated with metformin. METHODS Baseline data from patients in previously published meta-analysis and included randomized controlled trials (RCTs) were extracted to predict survival, long-term efficacy, and costs for each group using the United Kingdom prospective diabetes study outcome model 2.1. The cost-effectiveness of 5 GLP-1RAs (liraglutide, lixisenatide, exenatide, dulaglutide, and semaglutide) was analyzed by cost- utility analysis. Sensitivity analysis and scenario analysis were also performed to verify the uncertainty of basic analysis results. RESULTS A total of 21 RCTs with 6 796 patients were included. Survival analysis curves showed the superiority of semaglutide in reducing the risk of death from cardiovascular disease and dulaglutide in reducing the risk of all-cause mortality over other GLP- 1RAs. The cost-utility analysis showed that the five drugs were economically superior to inferior in the order of lixisenatide, semaglutide, exenatide, dulaglutide, and liraglutide; one-way and probabilistic sensitivity analyses indicated that the results were robust. The scenario analysis results indicated that the price of semaglutide should decrease by at least 54.64% to 369.21 yuan, which is cost-effectiveness compared to lixisenatide. CONCLUSIONS For T2DM patients in China with poor glycemic control after treatment with metformin, lixisenatide and semaglutide may be considered as the preferred regimen.
