[Shenfu Injection regulates macrophage polarization via TLR4/NF-κB pathway to reduce inflammation in chronic heart failure].

This study aimed to investigate the therapeutic effect of Shenfu Injection on mice with chronic heart failure(CHF) and its effect on macrophage polarization. C57BL/6J mice were randomly assigned to the normal and model groups. The CHF model was established by intraperitoneal injection of isoproterenol(ISO, 7.

[Mechanisms of NLRP3 inflammasome-mediated pyroptosis in chronic heart failure and research progress in traditional Chinese medicine].

Chronic heart failure(CHF) is a severe cardiovascular disease characterized by a complex pathogenesis involving myocardial structural and functional abnormalities and the activation of inflammatory responses. The NOD-like receptor thermal protein domain-associated protein 3(NLRP3) inflammasome, acting as a sensor for inflammatory cells, plays a pivotal role in the development of CHF. Research indicates that the activation of the NLRP3 inflammasome can induce inflammatory responses, leading to cardiac inflammation and impairing myocardial function, and it is correlated with the severity of CHF.

[Shenfu Injection improves chronic heart failure by regulating pyroptosis based on NLRP3/caspase-1 pathway].

This study investigated the mechanisms and targets of Shenfu Injection in the intervention in chronic heart failure(CHF) through the NOD-like receptor thermal protein domain associated protein 3(NLRP3)/caspase-1 signaling pathway. A CHF model was induced in rats by subcutaneous injection of isoproterenol. Model rats were randomly divided into a model group, a Shenfu Injection group, and a MCC950(NLRP3 inhibitor) group, and a blank group was also set up as a control.

[Protective effect of Shenfu Injection on regulation of autophagy in rats with chronic heart failure based on PI3K/Akt/mTOR pathway].

This study aimed to investigate the mechanism and target sites of Shenfu Injection in the intervention of chronic heart fai-lure based on the PI3K/Akt/mTOR autophagy signaling pathway. The chronic heart failure model was induced in rats by subcutaneous injection of isoproterenol. The model rats were randomly divided into model group, Shenfu Injection group, and 3-methyladenine autophagy inhibitor(3-MA) group.

[Pathogenesis of chronic heart failure in rats based on ferroptosis-mediated oxidative stress and intervention effect of Shenfu Injection].

This study aims to investigate the pathogenesis of chronic heart failure based on ferroptosis-mediated oxidative stress and predict the targets of Shenfu Injection in treating chronic heart failure. A rat model of chronic heart failure was established by the isoproterenol induction method. According to the random number table method, the modeled rats were assigned into three groups: a model group, a Shenfu Injection group, and a ferrostatin-1(ferroptosis inhibitor) group.

[Mechanism of ferroptosis in chronic heart failure based on theory of "harmful hyperactivity and responding inhibition"].

Chronic heart failure is the end stage of heart diseases caused by multiple causes. Myocardial cell injury is the key cause of cardiac function deterioration. Ferroptosis, an iron-dependent programmed death mode, is characterized by iron overload and excessive accumulation of lipid peroxides.

[Research trends and hot spots of Chuanxiong Rhizoma from 2010 to 2023].

This study aims to objectively and quantitatively analyze the research status and hot spots of Chuanxiong Rhizoma and provide guidance for further research and clinical application of this herbal medicine. Firstly, the research articles involving Chuanxiong Rhizoma from 2010 to 2023 were retrieved from seven databases including Web of Science, PubMed, Medline, CNKI, VIP, Wanfang, and SinoMed. Then, NoteExpress and manual reading were employed to complete the de-duplication and screening of the articles, and the annual number of publications and journals was analyzed.

[Protective effect of Shenfu Injection on rats with chronic heart failure based on HMGB1/TLR4/NF-κB signaling pathway].

The study aimed to explore the mechanism and targets of Shenfu Injection in the regulation of inflammatory injury in chronic heart failure rats based on the high mobility group box-1/Toll like receptor 4/nuclear factor kappa-B(HMGB1/TLR4/NF-κB) signaling pathway. The rat model of chronic heart failure was established using isoproterenol. The modeled rats were divided into three groups by random number table: the model group, Shenfu group and glycopyrrolate group, and the normal group was also set.

Shenmai Injection Improves Hypertensive Heart Failure by Inhibiting Myocardial Fibrosis via TGF-β 1/Smad Pathway Regulation.

Objective: To study effects of Shenmai Injection on hypertensive heart failure and its mechanism for inhibiting myocardial fibrosis.

Methods: Salt-sensitive (Dahl/SS) rats were fed with normal diet (0.3% NaCl) and the high-salt diet (8% NaCl) to observe the changes in blood pressure and heart function, as the control group and the model group.

[Analysis of animal models of hypertension based on characteristics of clinical symptoms of Chinese and western medicine].

Hypertension, a cardiovascular disease with main clinical manifestations of dizziness and elevated blood pressure, especially elevated arterial pressure, features high prevalence rate and low control rate, which affects patients' quality of life. Therefore, establishing a good animal model of hypertension is of great significance for its diagnosis and clinical prevention and treatment. Based on the clinical characteristics of hypertension in traditional Chinese and western medicine, this study summarized the advantages and disadvantages of current hypertension animal models: gene-related model, surgery-caused model, drug-induced model, and environment-induced model, and investigated the similarity to the clinical symptoms in traditional Chinese medicine and Western medicine.

[Animal model analysis of rheumatoid arthritis based on clinical characteristics of Chinese and Western medicine].

Rheumatoid arthritis(RA) is an autoimmune disease involving multiple joints bilaterally with symmetrical polyarthritis as the main symptom. The high disability rate of this disease seriously affects the quality of life of patients and even threatens their lives. The establishment of a good animal model is of great significance for the diagnosis and clinical prevention of RA.

PCSK9 promotes the secretion of pro-inflammatory cytokines by macrophages to aggravate H/R-induced cardiomyocyte injury via activating NF-κB signalling.

The upregulation of proprotein convertase subtilisin/kexin type 9 (PCSK9) was reported to be involved in regulating the levels of inflammatory markers and apoptosis in macrophages. This study aims to investigate the function and regulation of PCSK9 in myocardial ischaemia. The results of our study showed dramatically increased expression of PCSK9 induced by hypoxia/reoxygenation (H/R) stress rather than by apoptosis in primary murine cardiomyocytes and HL-1 cells.
