Objective To investigate the impact of minocycline(MC)on myocardial cell damage in rats with chronic heart failure(CHF)by regulating the hypoxia-inducible factor 1α(HIF-1α)/B-cell lymphoma-2/adenovirus E1B 19-kDa interacting protein(BNIP3).Methods All rats were randomly divided into Sham,CHF,positive drug(LP),low dose MC,high dose MC(HMC),and HMC+HIF-1α activator(DMOG)groups.Cardiac function was detected using echocardiography.HE staining,transmission electron microscopy,and TUNEL assay were used to evaluate myocardial pathology and apoptosis.Enzyme-linked immunosorbent assay was applied to quantify tumor necrosis factor α(TNF-α),interleukin-1β,superoxide dismutase(SOD),and malondialdehyde(MDA).Quantitative real-time PCR was used to detect the mRNA levels of Bcl-2 and Bcl-2-related X protein(Bax),while Western blotting was applied to detect the expres-sion of HIF-1α,BNIP3,Beclin-1,and microtubule-associated protein 1 light chain 3(LC3)proteins.Results Compared to rats in the sham group,rats from the CHF group exhibited increased left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),cell apoptosis rate,TNF-α,IL-1β,MDA,Bax,HIF-1α,BNIP3,Beclin-1,and LC3Ⅱ/Ⅰwith decreased left ventricular ejection fraction(LVEF),left ventricular shortening fraction(LVFS),SOD,and Bcl-2 levels(P<0.05).Compared with CHF group,rats from LP group,LMC group and HMC group exhibited decreased levels of LVEDD,LVESD,apoptosis rate,TNF-α,IL-1β,MDA,Bax,HIF-1α,BNIP3,Beclin-1,LC3Ⅱ/Ⅰ,and increased levels of LVEF,LVFS,SOD and Bcl-2(P<0.05).DMOG attenuated the protective effect of high-dose MC on myocardial cell damage in rats of the CHF group(P<0.05).Conclusion MC improves myocardial cell damage in rats of CHF group by inhibiting the HIF-1α/BNIP3 signaling pathway.

With the continuous deepening of medical insurance payment reform, the implementation of the ambulatory patient groups(APG) based point system for payment has posed new challenges to the quality management of outpatient electronic medical record writing, as well as the supervision and operation management of outpatient costs in hospitals. A certain hospital began information technology construction in July 2021. By introducing diagnostic grouping functions into the outpatient electronic medical record system, the hospital strengthened the standardization of medical record writing. It also established an intelligent audit system for medical insurance costs to conduct full-process supervision of outpatient medical expenses and developed an intelligent operation analysis system for outpatient APG to provide a basis for hospital operation management decisions and performance distribution. These measures effectively improved the quality of outpatient medical record, reduced outpatient medical costs, and optimized their structure. The application of the intelligent medical insurance audit system also effectively prevented certain non-compliant issues in medical insurance payments, which can provide a reference for other medical institutions.

Objective To investigate the mechanism of Astragali Complanati Semen in the prevention and treatment of hyperlipidemia;To provide theoretical basis for its clinical application.Methods The active components of Astragali Complanati Semen were retrieved and screened through TCMSP,TCMID and TDT databases to obtain the action targets of the active components.Hyperlipidemia targets were obtained through GeneCards,DisGeNET,and TTD databases,and the drug active component targets were intersected with hyperlipidemia targets.Cytoscape 3.9.1 software and STRING database were used to construct active component-target network and protein-protein interaction network,screening for major active components and core targets.GO and KEGG pathway enrichment analysis was performed using the DAVID database,and the CB-Dock platform was used for molecular docking.HepG2 cells were induced to construct a high-fat cell model using oleic acid and palmitic acid,and intervened with Astragali Complanati Semen freeze-dried powder solution.The mRNA expression of the core target was detected by RT-qPCR.Results A total of 10 active components of Astragali Complanati Semen and 67 potential action targets of hyperlipidemia were identified,involving signaling pathways such as AGE-RAGE,lipid metabolism,HIF-1,etc.Experimental results showed that intervention with Astragali Complanati Semen could reduce lipid accumulation in the high-lipid cell model,with an optimal intervention concentration of 500 μg/mL;RT-qPCR revealed significant down-regulation of TNFα,IL6,AKT1,PPARG,and other genes after intervention with Astragali Complanati Semen.Conclusion Astragali Complanati Semen exerts lipid-regulating effects through multiple targets and pathways,providing a basis for its application in the prevention and treatment of hyperlipidemia.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To study the influence of different region of interest (ROI) sketch on measurement results in the diagnosis of breast cancer by imaging technology of intravoxel incoherent motion (IVIM) .Methods:The clinical dataes of 84 patients with breast mass lesions from Apr. 2017 to Oct. 2021 were collected, all patients underwent IVIM-DWI. ROI was delineated at the maximum level of the mass by tumor contour method and fixed radius method. The apparent diffusion coefficient (ADC), real diffusion coefficient (D), perfusion fraction (f) and pseudo diffusion coefficient (D *) were recorded. IVIM-DWI parameters of patients with benign and malignant breast tumors were compared. The influence of ROI delineation by tumor contour method and fixed radius method on the results of IVIM related parameters were compared. Results:Forty-six of 84 patients were malignant and 38 benign masses. The ADC and D values of patients in the malignant group were (0.98±0.24) ×10 -3 mm 2/s, (0.79±0.22) ×10 -3 mm 2/s in the malignant group, significantly lower than those in the benign group [ (1.65±0.43) ×10 -3 mm 2/s, (1.41±0.35) ×10 -3 mm 2/s], and the f value and D * value were (5.65±1.13) %, (43.89±8.05) ×10 -3 mm 2/s, significantly higher than those in the benign group [ (3.84±1.57) %, (37.77±9.3) ×10 -3 mm 2/s]. The differences were statistically significant ( t=9.01, 9.89, 6.13, 3.23; all P<0.05). The results obtained by using the tumor fixed radius method to delineate ROI showed that the ADC and D values of (0.96±0.27) ×10 -3 mm 2/s (0.81±0.23) ×10 -3 mm 2/s in the malignant group were significantly lower than those in the benign group [ (1.66±0.39) ×10 -3 mm 2/s, 1.39±0.37) ×10 -3 mm 2/s], and the f and D * values were (5.69±1.15) %, (43.94±7.98) ×10 -3 mm 2/s, which were significantly higher than those in the benign group [ (3.86±1.49) %, (38.01±8.46) ×10 -3 mm 2/s]. The differences were statistically significant ( t=9.69, 8.78, 6.35, 3.30; all P<0.05) .The 95% consistency interval range of ADC difference, D value difference, f value difference, and D * value difference obtained by using tumor contour method to delineate ROI was smaller than that of tumor fixed radius method. Conclusions:The IVIM has high accuracy in the diagnosis of breast cancer, the IVIM parameters obtained from ROI delineation by tumor contour method have good repeatability.
