The European Society of Cardiology (ESC) released the "2024 ESC guidelines for the management of elevated blood pressure and hypertension" on August 30, 2024. This guideline updates the 2018 "Guidelines for the management of arterial hypertension." One notable update is the introduction of the concept of "elevated blood pressure" (120-139/70-89 mm Hg). Additionally, a new systolic blood pressure target range of 120-129 mm Hg has been proposed for most patients receiving antihypertensive treatment. The guideline also includes numerous additions or revisions in areas such as non-pharmacological interventions and device-based treatments for hypertension. This article interprets the guideline's recommendations on definition and classification of elevated blood pressure and hypertension, and cardiovascular disease risk assessment, diagnosing hypertension and investigating underlying causes, preventing and treating elevated blood pressure and hypertension. We provide a comparison interpretation with the 2018 "Guidelines for the management of arterial hypertension" and the "2017 ACC/AHA guideline on the prevention, detection, evaluation, and management of high blood pressure in adults."

BACKGROUND:Prolyl hydroxylase domain 2(PHD2)inhibitors can regulate bone metabolism and relieve osteoporosis in ovariectomized rats.cpd17 is a small molecule oral PHD2 inhibitor newly developed by China Pharmaceutical University.It is effective in the treatment of renal anemia with few side effects,but its effect on bone formation and bone resorption is still unclear. OBJECTIVE:To investigate the effects of cpd17 on mouse osteogenic precursor cells. METHODS:Osteogenic precursor cells were treated with cpd17.Alkaline phosphatase activity and extracellular matrix mineralization were measured,and the expression levels of osteogenesis-and osteoclastogenesis-related markers,as well as PHD2 and hypoxia-inducible factor 1α,were detected.After inhibition of the hypoxia-inducible factor 1α pathway using LW6(a hypoxia-inducible factor 1α pathway inhibitor),alkaline phosphatase activity and extracellular matrix mineralization were detected again,as well as the expression levels of osteogenesis-and osteoclastogenesis-related markers,PHD2 and hypoxia-inducible factor 1α. RESULTS AND CONCLUSION:cpd17 significantly enhanced alkaline phosphatase activity and extracellular matrix mineralization,up-regulated the expression of osteogenesis-related markers,down-regulated the expression of osteoclastogenesis-related markers,up-regulated the expression of hypoxia-inducible factor 1α,down-regulate the expression of PHD2.However,cpd17's effects were significantly attenuated by LW6.To conclude,the PHD2 inhibitor cpd17 promotes osteogenic differentiation and inhibits osteoclastic differentiation through activation of the hypoxia-inducible factor 1α signaling pathway.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C0), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug-drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

Objective:To evaluate whether the mechanism by which mesenchymal stem cell-derived exosomes (MSC-exo) mitigated endotoxin-induced lung injury was related to the heme oxygenase-1 (HO-1)/mitochondrial signaling pathway in alveolar macrophages of mice.Methods:In vivo experiment Eighteen C57BL/6 wild-type (WT) mice were divided into 3 groups ( n=6 each) using a random number table method: control group (C group), lipopolysaccharide (LPS) group (L group) and LPS + MSC-exo group (LM group). Six HO-1 conditional knockout mice (HO-1 -/-) were selected and served as HO-1 -/- + MSC-exo + LPS group (HML group). The model of endotoxin-induced lung injury was prepared by injection of LPS 15 mg/kg. MSC-exo (2×10 11 particles) was intravenously injected at 1 h before injection of LPS in LM group. MSC-exo (2×10 11 particles) was intravenously injected and 1 h later LPS was injected in HML group. The expression of HO-1 in macrophages was detected using immunofluorescence, lung injury was assessed following hematoxylin-eosin staining, the wet/dry weight ratio (W/D ratio) was determined, and the mitochondrial morphology was observed with a transmission electron microscope. Cell experiment Alveolar macrophages (MH-S) were divided into 4 groups ( n=20 each) using a random number table method: control group (C group), LPS+ phosphate buffer solution group (LP group), LPS+ MSC-exo group (LM group), and LPS+ MSC-exo+ HO-1 small-interfering RNA group (LMS group). Cells were incubated for 12 h with LPS 10 μg/ml in LP, LM and LMS groups. In addition, LM group was incubated with MSC-exo 100 μg/ml, LP group was incubated with the equal volume of phosphate buffer solution, and the alveolar macrophages were transfected with HO-1 small interfering RNA and incubated with MSC-exo 100 μg/ml in LMS group at the same time. The concentrations of interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) in supernatant were measured by enzyme-linked immunosorbent assay, HO-1 expression was detected by Western blot, the mitochondrial membrane potential was measured using JC-1 staining, and the expression of reactive oxygen species (ROS) was detected by fluorescence. Results:In vivo experiment Compared to C group, the lung injury score and W/D ratio were significantly increased ( P<0.05), the fluorescence signal of HO-1 in macrophages was enhanced, and the damage to mitochondria was aggravated in L group. Compared to L group, the lung injury score and W/D ratio were significantly decreased ( P<0.05), the fluorescence signal of HO-1 in macrophages was enhanced, and the damage to mitochondria was reduced in LM group. Compared to LM group, the lung injury score and W/D ratio were significantly increased ( P<0.05), macrophages had no HO-1 fluorescence signal, and the damage to mitochondria was aggravated in HML group. Cell experiment Compared to C group, the concentrations of IL-1β and TNF-α in supernatant were significantly increased, the expression of HO-1 was up-regulated ( P<0.05), and the mitochondria predominantly exhibited green JC-1 fluorescence, accompanied by an enhanced ROS fluorescence signal in LP group. Compared to LP group, the concentrations of IL-1β and TNF-α in supernatant were significantly decreased, the expression of HO-1 was up-regulated ( P<0.05), and the mitochondria predominantly exhibited red JC-1 fluorescence, accompanied by a weakened ROS fluorescence signal in LM group. Compared to LM group, the concentrations of IL-1β and TNF-α in supernatant were significantly increased, the expression of HO-1 was down-regulated ( P<0.05), and the mitochondria predominantly exhibited green JC-1 fluorescence, accompanied by an enhanced ROS fluorescence signal in LMS group. Conclusions:The mechanism by which MSC-exo attenuates endotoxin-induced lung injury may be related to up-regulation of HO-1 expression in alveolar macrophages and reduction of mitochondrial damage in mice.

Objective:To explore the predictive value of models based on clinical parameters, deep learning radiomics (DLR) from CT images, and traditional handcrafted radiomics (HCR) in assessing pathological complete response (pCR) after neoadjuvant radiotherapy combined with medical therapy in patients with esophageal cancer.Methods:A retrospective study was conducted on 130 patients with locally advanced esophageal cancer who underwent neoadjuvant radiotherapy combined with medical therapy followed by surgery at the First Affiliated Hospital of the University of Science and Technology of China from August 1, 2018, to August 31, 2024. Patients were randomly divided into a training set ( n=91) and a validation set ( n=39) at a ratio of 7:3. Logistic regression analysis was performed to identify clinical independent risk factors associated with pCR. DLR and HCR features were extracted from the tumor and the 5 mm peritumoral region on planning CT images. Features for modeling were selected using t-test, Mann-Whitney U test or Fisher exact probability method, least absolute shrinkage and selection operator (LASSO) regression to calculate the radiomics score (Rad-score). A nomogram was then constructed by integrating the clinical risk factors. The predictive performance of each model was evaluated using the area under the receiver operating characteristic curve (AUC), accuracy, sensitivity, specificity, and decision curve analysis (DCA) to assess clinical benefits. Results:Multivariate logistic regression analysis identified body weight ( OR=1.101, 95% CI: 1.029-1.177, P=0.005) and lymph node positivity ( OR=0.100, 95% CI: 0.014-0.727, P=0.023) as independent predictors of pCR. The peritumoral DLR-HCR model showed superior predictive performance, with AUCs of 0.870 (95% CI: 0.799-0.942) in the training set and 0.866 (95% CI: 0.750-0.982) in the validation set. The combined model incorporating clinical parameters achieved the best performance, with AUCs of 0.903 (95% CI: 0.845-0.962) and 0.888 (95% CI: 0.782-0.994) in the training and validation sets, respectively. Conclusions:The combined model integrating peritumoral DLR-HCR features with clinical parameters provides excellent predictive value for pCR after neoadjuvant radiotherapy combined with medical therapy in esophageal cancer and offers valuable guidance for personalized treatment strategies.

Objective:To find out whether the performance of a China-made high performance human centrifuge can satisfy the need of high G training by conducting physiological experiments.Methods:The dynamic physical performance of the anti-G equipment with the human centrifuge was tested before 5 subjects underwent the gradual-onset rate (GOR) run and rapid onset rate (ROR) run experiments. The G onset rate of GOR was 0.1 G/s. The relaxed G-tolerance under GOR (GOR tolerance 1) and the anti-G straining maneuver aided G-tolerance under GOR (GOR tolerance 2) were tested respectively. The G onset rate of ROR was 3 G/s, and the closed-loop mode and pre-programed mode were employed respectively. The closed-loop mode involved 5 G 10 s and 8 G 10 s, where the subjects were required to manipulate the joystick to ensure that the real-time curve of the load matched the target curve. In the pre-programmed mode, the subjects were exposed to 8 G 10 s passively, without any operation requirements. A subjective evaluation form was filled out by subjects after the experiments, in which the 14 indexes for evaluation were about the gondola facilities and environment, running processes, medical monitoring and overall assessment.Results:Both the oxygen mask and anti-G suit achieved full pressurization within 2.0 s. The GOR tolerance 1 was [4.0(3.8, 4.6)] G while the GOR tolerance 2 was (6.2±0.5) G, suggesting a statistically significant difference ( Z=-2.63, P=0.008). The HP anti-G straining maneuver effect was (2.0±0.6) G. All the 5 subjects finished the 5 G 10 s experiment in a closed-loop mode. Three of them attempted 8 G 10 s in the closed-loop mode (1 subject achieved only 7.6 G peak acceleration, and the other 2 achieved full 8 G 10 s exposure), while the remaining 2 completed the 8 G 10 s in the pre-programmed mode. In the closed-loop mode, it was found that the stick force was too strong, the guiding G and real time G curve were not easy to distinguish for some of the subjects because the curve colors were similar, and that the subjects could not see the G curves clearly in case of a grayout. Both seat comfort and the voice quality of communication got the highest subjective assessment score [5.0(4.0, 5.0)] while the sensation of tumble got the lowest score (2.8±0.8). The median or mean scores of other subjective evaluation indexes ranged from 3.0 to 4.6 points. The overall score of subjective assessment was [4.0(3.5, 4.0)] points. Conclusions:The China-made high performance human centrifuge can meet the requirements of 8.0 G high G training, which can be made more effective and comfortable if the strong stick force and feeling of tumble during stop running are overcome.
