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."

ObjectiveTo explore the regulatory effect and mechanism of Danggui Shaoyaosan combined with Yinchenhaotang on lipid metabolism in the mouse model of type 2 diabetes mellitus （T2DM） complicated with metabolic dysfunction-associated steatotic liver disease （MASLD） based on network pharmacology and animal experiments. MethodsTwenty-four MKR transgenic diabetic mice were randomly allocated into 4 groups： Model， low-dose （12.6 g·kg^-1） Chinese medicine （concentrated decoction of Danggui Shaoyaosan combined with Yinchenhaotang）， high-dose （25.2 g·kg^-1） Chinese medicine， and Western medicine （metformin， 0.065 g·kg^-1）. Six FVB mice were used as the normal group. All groups were treated for 6 consecutive weeks. The mice in the drug treatment groups were administrated with corresponding agents by gavage， and those in the normal group and model group received the same volume of distilled water. Fasting blood glucose， body weight， liver weight， glucose tolerance， liver function indicators， blood lipid levels， and pathological changes in the liver were evaluated for each group. Network pharmacology was employed to analyze the targets and pathways of Danggui Shaoyaosan combined with Yinchenhaotang in the treatment of T2DM complicated with MASLD. Molecular biological techniques were used to verify the enriched key targets. ResultsCompared with the model group， each treatment group showed reduced fasting blood glucose， body weight， aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， and liver weight （P<0.01）. The high-dose Chinese medicine group was superior to the low-dose group in reducing low-density lipoprotein （LDL）， increasing high-density lipoprotein （HDL）， and recovering glucose tolerance （AUC） and ALT （P<0.05）， with the effect similar to that of the Western medicine group. Morphologically， Chinese medicine groups showed reduced lipid accumulation and alleviated pathological damage in the liver tissue， with the high-dose group demonstrating more significant changes. Network pharmacology results showed that Danggui Shaoyaosan combined with Yinchenhaotang may exert therapeutic effects through multiple targets such as fatty acid synthase （FAS）， acetyl-CoA carboxylase （ACC）， B-cell lymphoma-2 （Bcl-2）， MYC oncogene （MYC）， and interleukin-1β （IL-1β）. Western blot showed that compared with the model group， the treatment groups demonstrated down-regulated protein levels of FAS and ACC （P<0.01） and up-regulated protein levels of peroxisome proliferator-activated receptor γ coactivator-1α （PGC-1α） and UCP1 （P<0.01）. Compared with the low-dose Chinese medicine group， the high-dose Chinese medicine group exhibited down-regulated protein levels of FAS and ACC and up-regulated protein levels of PGC-1α and UCP1 （P<0.05）. ConclusionDanggui Shaoyaosan combined with Yinchenhaotang has the effect of ameliorating T2DM complicated with MASLD and can improve the liver lipid metabolism by up-regulating the protein levels of Fas and ACC and down-regulating the protein levels of PGC-1α and UCP1.

Objective To externally validate a prediction model based on clinical and CT imaging features for the preoperative identification of high-grade patterns (HGP), such as micropapillary and solid subtypes, in early-stage lung adenocarcinoma, in order to guide clinical treatment decisions. Methods This study conducted an external validation of a previously developed prediction model using a cohort of patients with clinical stage ⅠA lung adenocarcinoma from the Fourth Hospital of Hebei Medical University. The model, which incorporated factors including tumor size, density, and lobulation, was assessed for its discrimination, calibration performance, and clinical impact. Results A total of 650 patients (293 males, 357 females; age range: 30-82 years) were included. The validation showed that the model demonstrated good performance in discriminating HGP (area under the curve>0.7). After recalibration, the model's calibration performance was improved. Decision curve analysis (DCA) indicated that at a threshold probability>0.6, the number of HGP patients predicted by the model closely approximated the actual number of cases. Conclusion This study confirms the effectiveness of a clinical and imaging feature-based prediction model for identifying HGP in stage ⅠA lung adenocarcinoma in a clinical setting. Successful application of this model may be significant for determining surgical strategies and improving patients' prognosis. Despite certain limitations, these findings provide new directions for future research.

Myelodysplastic syndrome (MDS), a myeloid tumor derived from the malignant clones of hematopoietic stem cells, has an annually increasing incidence. The contemporary research direction has shifted to analyzing the synergistic effect of immune surveillance collapse and abnormal bone marrow microenvironment in the pathological process of MDS. Against this backdrop, the immune checkpoint molecule TIM3 has emerged as a key target because of its persistently high expression on the surface of important immune cells such as T and NK cells. The abnormal activation of the TIM3 pathway is the mechanism by which solid tumors and hematological malignancies achieve immune escape and is a key hub in the formation of immune exhaustion phenotypes. This work integrates the original discoveries of our team with the latest international progress, systematically demonstrating the bidirectional regulatory network of TIM3 between the malignant clone proliferation of MDS and the immunosuppressive microenvironment. Integrating the evidence from emerging clinical trials allows us to consider the clinical significance of TIM3-targeted blocking for MDS, providing a transformative path to overcome the resistance of traditional treatments and marking a new chapter in the active immune reconstitution of MDS treatment.

Aim To study the effects of Taohong Siwu Tang(TSD)on serum lipid metabolites in rats with abnormal uterine bleeding(AUB),and to analyze the mechanism of action of TSD in improving lipid metabo-lism disorders in AUB.Methods The rat model of AUB was replicated by the method of incomplete abor-tion with drugs,and the lipid metabolites of serum were detected by applying UPLC-Q-Exactive Orbitrap/MS technology,and combined with the principal com-ponent analysis and orthogonal partial least squares-discriminant analysis to screen for differential lipids,the changes of lipids in serum before and after the in-tervention of TSD were clarified.Results A total of 11 differential lipids were screened,mainly phosphati-dyl inositol,phosphatidic acid,phosphatidyl ethanola-mine,phosphatidyl serine,sterol lipids,ceramide,acrylolipids and fatty acids.The screened differential lipids all tended to regress to normal after the adminis-tration of TSD intervention.Conclusion Improvement of AUB by TSD may be related to lipid metabolism such as phosphatidic acid,phosphatidyl inositol,phos-phatidyl ethanolamine,phosphatidyl serine,and ce-ramide.

Coronary atherosclerotic heart disease(CHD)is an ischemic cardiovascular condition caused by the narrowing or blockage of the vascular lumen due to coronary atherosclerosis.Clinically,it presents as angina pectoris,heart failure,or sud-den cardiac death,and stands as one of the primary causes of mortality among both urban and rural populations in China.Cir-cRNA,classified as non-coding RNAs,can function as upstream regulatory molecules for miRNA or RNA-binding proteins.They actively participate in various pathological processes associated with CHD,including endothelial cell dysfunction,smooth mus-cle cell migration,macrophage-derived foam cell formation,an-giogenesis,myocardial injury,and repair,as well as post-in-farction heart failure.The expression pattern of these molecules is highly specific to the illness and tissue,indicating their poten-tial as therapeutic targets for disease management and as biomar-kers.Furthermore,they also open up new avenues for drug tar-get development in the field of traditional Chinese medicine.This article aims to provide an overview of the recent research progress on circRNA in the regulation of coronary heart disease,as well as the mechanisms involved in traditional Chinese medi-cine.It serves as a valuable reference for future research on cor-onary heart disease.

Objective To observe the value of intravascular ultrasound(IVUS)for assisting endovascular therapy for renal artery stenosis(RAS).Methods Thirty patients with RAS who underwent endovascular therapy were retrospectively analyzed.Parameters of renal artery and plaques in RAS segment measured with CT angiography(CTA)and IVUS before treatment were compared.Bland-Altman diagram was performed to evaluate the consistency of lumen cross-sectional stenosis rate and plaque eccentricity index between CTA and IVUS.The stent parameters measured with IVUS were recorded immediately after implantation of balloon-expandable covered stents.Results Before treatment,the minimum lumen diameter,lumen cross-sectional stenosis rate and stenotic segment length of IVUS were all larger,while maximum lumen diameter and lumen eccentricity index of IVUS were both smaller than those of CTA(all P＜0.05).No significant difference of plaque eccentricity index,plaque type nor stenosis distal remodeling was found between CTA and IVUS(all P＞0.05).The average difference between IVUS and CTA for evaluating lumen cross-sectional stenosis rate and plaque eccentricity index was-0.020(-0.096,0.050)and-0.020(-0.130,0.091),respectively.The consistency of IVUS and CTA for evaluating plaque eccentricity index was better than that of lumen cross-sectional stenosis rate.The stent symmetry,stent eccentricity index,stent expansion coefficient and stenosis coverage rate immediately after implantation measured with IVUS was(82.69±14.61)%,(1.54±9.16)%,(99.81±10.70)%and 100%,respectively.Among 30 cases,2 cases(2/30,6.67%)underwent postdilation since poor stent apposition.Conclusion IVUS could assist evaluating lumen and plaque parameters of stenotic renal arteries,guiding stent release and real-timely monitoring the effect of endovascular therapy.
