ObjectiveTo decipher the mechanism by which Zuoguiwan （ZGW） treat hyperthyroidism in rats with kidney-Yin deficiency based on the dopamine receptor D4 （DRD4）/nicotinamide adenine dinucleotide phosphate （NADPH） oxidase 4 （NOX4） signaling pathway. MethodsThe rat model of kidney-Yin deficiency was induced by unilateral intramuscular injection of dexamethasone （0.35 mg·kg^-1）. After successful modeling， the rats were randomized into model， methimazole （positive control， 5 mg·kg^-1）， low-， medium-， and high-dose （1.85， 3.70， 7.40 g·kg^-1， respectively） ZGW， and normal control groups. After 21 days of continuous gavage， the behavioral indexes and body weight changes of rats were evaluated. The pathological changes of the renal tissue were observed by hematoxylin-eosin staining. The serum levels of thyroid hormones ［triiodothyronine （T₃）， thyroxine （T₄）， thyroid-stimulating hormone （TSH）］， renal function indexes ［serum creatine （Scr） and blood urea nitrogen （BUN）］， energy metabolism markers ［cyclic adenosine monophosphate （cAMP） and cyclic guanosine monophosphate （cGMP）］， and oxidative stress-related factors ［superoxide dismutase （SOD）， malondialdehyde （MDA）， and NADPH）］ were measured by enzyme-linked immunosorbent assay （ELISA）. Western blot was employed to analyze the expression of DRD4， NOX4， mitochondrial respiratory chain complex proteins ［NADH：ubiquinone oxidoreductase subunit S4 （NDUFS4） and cytochrome C oxidase subunit 4 （COX4）］， and inflammation-related protein ［tumor necrosis factor-alpha （TNF-α）， interleukin-6 （IL-6）， p38 mitogen-activated protein kinase （MAPK）］ pathway in the renal tissue. ResultsCompared with the normal group， the model group showed mental malaise， body weight decreases （P<0.01）， inflammatory cell infiltration in the renal tissue， a few residual parotid glands in the thyroid， elevations in serum levels of T₃， T₄， Scr， BUN， cAMP， cAMP/cGMP， MDA， and NADPH （P<0.01）， down-regulation in protein levels of TSH， SOD， and DRD4 （P<0.05， P<0.01）， and up-regulation in expression of NOX4， p-p38 MAPK/p38 MAPK， and inflammatory factors （P<0.01）. Compared with the model group， ZGW increased the body weight （P<0.05， P<0.01）， reduced the infiltration of renal interstitial inflammatory cells， restored the thyroid structure and follicle size， lowered the serum levels of T₃， T₄， Scr， BUN， cAMP， cAMP/cGMP， MDA and NADPH （P<0.05， P<0.01）， up-regulated the expression of TSH， SOD and DRD4 （P<0.05， P<0.01）， and down-regulated the expression of NOX4， p-p38 MAPK/p38 MAPK， and inflammatory factors （P<0.05， P<0.01）. Moreover， high-dose ZGW outperformed methimazole （P<0.05）. ConclusionBy activating DRD4， ZGW can inhibit the expression of NOX4 mediated by the p38 MAPK pathway， reduce oxidative stress and inflammatory response， thereby ameliorating the pathological state of hyperthyroidism due to kidney-Yin deficiency. This study provides new molecular mechanism support for the clinical application of ZGW.

Evidence-based treatment strategies for patients with cardiovascular disease and diabetes have been updated in recent years. However, substantial gaps remain between guideline recommendations and clinical practice, which justify the urgent need to improve the quality of care for patients with these conditions. The Chinese Society of Cardiology and the Chinese Society of Diabetes, in collaboration with the American Heart Association and the American Diabetes Association, designed the China Diabetes Cardiovascular project. The China Diabetes Cardiovascular project is a nationwide registry study aimed at improving the quality of care for patients with acute coronary syndrome and diabetes in China. Launched in 2021, this project has enrolled 36 hospitals across mainland China. Patients with a primary discharge diagnosis of comorbid acute coronary syndrome and diabetes will be eligible to participate. Pre-defined performance measures will be adopted to evaluate the quality of care for these patients. Multiple quality improvement strategies will be adopted, including providing monthly quality reports based on these measures, conducting a series of training courses, and distributing educational materials. A comprehensive dataset, encompassing patients' characteristics, medical history, treatment before and during the current hospitalization, and discharge medications for secondary prevention, will be collected through a web-based data collection platform. This project has the potential to improve the quality of care and reduce the care disparities in the management of patients with these diseases. Moreover, with its comprehensive data collection, this project will provide a strong foundation for exploring key clinical questions.

Bone organoids can simulate the complex structure and function of the bone tissues, which makes them a frontier technology in organoid researches. Bone organoids show a tremendous potential of applications in bone disease modeling, bone injury repair, and medicine screening. Although advancements have been made so far in constructing bone organoids with functional structures like mineralization, bone marrow, trabecular bone, callus, woven bone, etc, the researches in this field are confronted with numerous challenges such as lack of standardized construction strategies and unified evaluation criteria, which limits their further promotion and application. To standardize researches in bone organoids, the Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, the Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, the Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and the Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine organized related experts to formulate Expert consensus on the construction, evaluation, and application of bone organoids ( version 2024) based on an evidence-based approach. A total of 17 recommendations were put forth, aiming to standardize researches and clinical applications of bone organoids and enhance their value in scientific research and clinical practice.

After acute episode phase, kidney biopsy was performed and acute tubular necrosis was diagnosed. During the follow-up period, the disease did not recur, and the renal function was normal.

AIM:To investigate the effects of ginkgetin on neurological deficit and angiogenesis induced by cerebral ischemia/reperfusion(I/R)and its underlying mechanism.METHODS:Sixty SD rats were randomly allocated into three groups:sham group,I/R model group,and ginkgetin(40 mg/kg)treatment(I/R+ginkgetin)group,with twenty rats in each group.The middle cerebral artery occlusion/reperfusion(MCAO/R)rat model was employed to simulate cere-bral I/R,and ginkgetin was administered continuously for 7 days following reperfusion.The cerebral infarction volume was quantified using TTC staining.Neuronal density in the ischemic penumbra was assessed through Nissl staining and immu-nohistochemistry for neuron-specific nuclear protein(NeuN).Microvessel density and angiogenesis in the ischemic pen-umbra of each group were analyzed using CD31 labeling and BrdU/von willebrand factor(vWF)double labeling immuno-fluorescence staining.Western blot analysis was performed to determine the levels of heat shock protein 70(HSP70),vas-cular endothelial growth factor(VEGF),and hypoxia inducible factor-1α(HIF-1α)in the ischemic penumbra.RE-SULTS:Compared with the I/R model group,the cerebral infarction volume was significantly reduced in ginkgetin treat-ment group(P<0.01),the number of neurons,the microvessel density,angiogenesis and the expression levels of HIF-1α,VEGF,and HSP70 in the ischemic penumbra were significantly increased(P<0.01).CONCLUSION:Ginkgetin exhibits the potential to augment angiogenesis and facilitate neurological function recovery in MCAO rats,while concur-rently upregulating the expression of HSP70,VEGF,and HIF-1α within the ischemic penumbra.

Background::Oral anti-coagulants (OAC) are the intervention for the prevention of stroke, which consistently improve clinical outcomes and survival among patients with atrial fibrillation (AF). The main purpose of this study is to identify problems in OAC utilization among hospitalized patients with AF in China.Methods::Using data from the Improving Care for Cardiovascular Disease in China-Atrial Fibrillation (CCC-AF) registry, guideline-recommended OAC use in eligible patients was assessed.Results::A total of 52,530 patients with non-valvular AF were enrolled from February 2015 to December 2019, of whom 38,203 were at a high risk of stroke, 9717 were at a moderate risk, and 4610 were at a low risk. On admission, only 20.0% (6075/30,420) of patients with a diagnosed AF and a high risk of stroke were taking OAC. The use of pre-hospital OAC on admission was associated with a lower risk of new-onset ischemic stroke/transient ischemic attack among the diagnosed AF population (adjusted odds ratio: 0.54, 95% confidence interval: 0.43–0.68; P <0.001). At discharge, the prescription rate of OAC was 45.2% (16,757/37,087) in eligible patients with high stroke risk and 60.7% (2778/4578) in eligible patients with low stroke risk. OAC utilization in patients with high stroke risk on admission or at discharge both increased largely over time (all P <0.001). Multivariate analysis showed that OAC utilization at discharge was positively associated with in-hospital rhythm control strategies, including catheter ablation (adjusted odds ratio [OR] 11.63, 95% confidence interval [CI] 10.04–13.47; P <0.001), electronic cardioversion (adjusted OR 2.41, 95% CI 1.65–3.51; P <0.001), and anti-arrhythmic drug use (adjusted OR 1.45, 95% CI 1.38–1.53; P <0.001). Conclusions::In hospitals participated in the CCC-AF project, >70% of AF patients were at a high risk of stroke. Although poor performance on guideline-recommended OAC use was found in this study, over time the CCC-AF project has made progress in stroke prevention in the Chinese AF population.Registration::ClinicalTrials.gov, NCT02309398.
