INTRODUCTION:Percutaneous coronary intervention (PCI)-related myocardial infarction (type 4a MI) and major periprocedural myocardial injury have been demonstrated leading to poor prognosis of patients with coronary heart disease (CHD) undergoing elective PCI and still remain high occurrence even after the therapy of dual antiplatelet agents and statins. Proprotein convertase subtilisin/kexin type 9 inhibitor alirocumab has been shown to be effectively in reducing the risk of acute MI (AMI). However, the effect of alirocumab on preventing PCI-related MI or major periprocedural myocardial injury in patients with CHD undergoing elective PCI remains uncertain.METHODS AND ANALYSIS:Alirocumab effect on Preventing Periprocedural ischaemic Events in coronary heart diseAse patients undergoing coronary StEnting trial is a multicentre, open-label, randomised controlled trial aiming to determine whether alirocumab could reduce the incidence of type 4a MI or major periprocedural myocardial injury in patients with CHD undergoing elective PCI. In total, 422 non-AMI CHD patients planned to undergo elective PCI will be randomly assigned to receive standard pharmacotherapy of CHD (control group) or additional use of subcutaneous alirocumab 75 mg 1 day before procedure (alirocumab group). The primary outcome is type 4a MI or major periprocedural myocardial injury defined as high-sensitivity cardiac troponin elevating above 5×99 th percentile upper reference limit in 48 hours after PCI. Patients will continue receiving standard pharmacotherapy or additional biweekly subcutaneous alirocumab 75 mg for 3 months according to the initial randomisation group. We will follow up for 3 months and record all the major adverse cardiovascular events (MACEs). Incidence of PCI-related MI or major periprocedural myocardial injury, and MACE in 3 months after PCI will be compared between control group and alirocumab group.ETHICS AND DISSEMINATION:Ethics approval has been obtained from the Medical Ethics Committee of the Third Affiliated Hospital of Sun Yat-sen University with approval number: (2022)02-140-01. The results of this study will be reported through peer-reviewed journals and conference presentations.TRIAL REGISTRATION NUMBER:ChiCTR2200063191.

Objective: The present observational study evaluated long-term management of hypertension in patients who received treatment with valsartan and amlodipine in a single-pill combination (Val/Aml SPC) in a real-world setting in China (Chinese Clinical Trial Registry number ChiCTR1900021324). Methods: This was a prospective, observational, multicenter, real-world registry study wherein patients with hypertension who had already received Val/Aml SPC (80/5 mg) for at least 4 weeks before study enrollment were observed for 1 year. Investigators recorded patient data every 3 months and essentially five times during the 1 year follow-up period. Effectiveness was assessed by the blood pressure (BP) control rate and average duration of treatment at the end of the study. Safety was monitored by the incidence of adverse events (AEs) and serious adverse events (SAEs). Results: Overall, 985 patients were enrolled (mean ± standard deviation [SD] age: 60.3 ± 11.5 years); of these, 894 were included in the full analysis set, 758 of whom completed the study. At baseline, BP was controlled (<140/90 mmHg) in 64.3% of patients on Val/Aml SPC for at least 4 weeks before enrollment. Office BP control rates significantly improved from baseline in 74.1% of patients at 1 year (p < .0001). Overall, 575 (87.0%) patients remained on Val/Aml SPC at 1 year (average exposure: 311.5 days). AEs were reported in 23.3% of patients. The majority of AEs were mild to moderate, and 0.6% of patients discontinued Val/Aml SPC because of SAEs. Conclusion: This study provides evidence that Val/Aml SPC effectively reduced BP over the long term among Chinese hypertensive patients, with a good adherence and tolerability profile, and that most hypertensive patients may benefit from this combination.

This study aimed to investigate the anti-oxidant and anti-hypertrophic effects of puerarin-7-O-glucuronide, a water-soluble puerarin metabolite. The anti-oxidant effects of puerarin-7-O-glucuronide were assessed by measurement of intracellular superoxide levels, total superoxide dismutase (SOD) activity, total anti-oxidant capacity, and glutathione (GSH)/glutathione disulfide (GSSG) ratio in cultured neonatal rat cardiomyocytes (NRCMs) stimulated with the xanthine oxidase (XO)/xanthine (X) system or angiotensin II. The activity of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase and expression of NADPH oxidase subunits p22phox and p47phox were determined. The anti-hypertrophic effects of puerarin-7-O-glucuronide in angiotensin II-challenged NRCMs were characterized by changes in cell morphology and expression of hypertrophic genes. In the pharmacokinetic study, the plasma concentration of puerarin-7-O-glucuronide was determined by rapid resolution–liquid chromatography–tandem mass spectrometry (RR-LC-MS/MS). Puerarin-7-O-glucuronide prevented XO/X-induced increase in intracellular superoxide production and decreases in total SOD activity, GSH/GSSG ratio, and total anti-oxidant capacity. Puerarin-7-O-glucuronide also reversed angiotensin II-induced increases in intracellular superoxide production and NADPH oxidase activity and decreases in total SOD activity. These anti-oxidant effects of puerarin-7-O-glucuronide were accompanied by downregulation of p22phox and p47phox. Furthermore, puerarin-7-O-glucuronide prevented angiotensin II-induced increases in cell surface area and perimeter, as well as changes in Nppa, Myh7, and Myh6. In the pharmacokinetic study, puerarin-7-O-glucuronide was cleared with a half-life of 0.94 h after intravenous administration. Puerarin could be detected in rat plasma, albeit in low concentration, as early as 5 min after intravenous administration of puerarin-7-O-glucuronide. These anti-oxidant and anti-hypertrophic properties of puerarin-7-O-glucuronide were similar to those of its parent compound puerarin. These results support the development of puerarin-7-O-glucuronide as a novel pharmaceutical agent for therapeutic application.

OBJECTIVETo investegate the role of calcineurin (CaN) and its downstream nuclear factor of activated T-cells (NFATc3) in abdominal aorta restenosis following balloon dilatation in rats.METHODSSD rats were randomly divided into sham-operated group, balloon group and cyclosporine A (CsA) group. The rats in the latter two groups were subjected to abdominal aorta injury with balloon dilatation, and those in CsA group were treated with CsA at the daily dose of 12.5 mg/kg from 3 days before the surgery to the end of the experiment. Thirty days afer the injury, histological analysis of the arterial wall was carried out with HE staining and immunohistochemistry. The expressions of CaN and NFATc3 in the abdominal aortas were detected with rea1-time PCR, and serum concentration of MCP-1 was determined using enzyme-linked immunosorbent assay.RESULTSIntimal hyperplasia with irregular thickness of the neointima was observed in the aorta of rats with ballon injury. In rats with CsA treatment, the area of the intimal layers and the ratio of the intimal to the medial layers were obviously lower than those in the balloon injury group (P<0.05). Compared to those in the sham-operated group, the expressions of calcineurin protein and mRNA and NFATc3 mRNA in the arterial wall and serum level of MCP-1 increased significantly in the ballon injury group (P<0.05). CsA treatment significantly suppressed aorta restenosis and the alterations of CaN, NFATc3 and serum MCP-1 induced by ballon dilatation (P<0.05).CONCLUSIONSCaN-NFATc3 signal transduction pathway mediates restenosis of rat abdominal aorta following ballon dilatation, and CsA can attenuate the restenosis by suppressing this pathway.

Objective:To determine the effects of Atorvastatin in elderly patients with heart failure of reduced ejection fraction (HFrEF),and its effects on left ventricular remodeling and inflammatory factors. Methods:Eighty elderly patients with HFrEF were randomly divided into the treatment group and the control group (n= 40 each). Both groups were given conventional anti-heart failure treatment. In addition,the treatment group was given Atorvastatin 20 mg every night,once/ d. The course of treatment was 6 months. The left ventricular ejection fraction (LVEF)and left ventricular end diastolic volume index (LVEDVI)were measured by echocardiography before and after treatment. The levels of serum lipids and tumor necrosis factor-α (TNF-α) were measured at the baseline,and 1 and 6 months after the treatment. Left ventricular ejection fraction (LVEF) and left ventricular end diastolic volume index (LVEDVI)were measured by echocardiography. Results:After the treatment,the TNF-α level in the two groups were significantly decreased,and the decrease was the largest at 1 month after the treatment. It was further decreased at 6 months after the treatment,and the treatment group decreased more significantly (P<0.05). The LVEF was significant improved at 1 month after the treatment,which was lasted for 6 months in the two groups,and the treatment group was improved more significantly (P<0.05). In the treatment group,LVEDVI was decreased at 1 month after the treatment,and decreased more significantly at 6 months after the treatment. In the control group,LVEDVI was decreased significantly at 6 months after the treatment. Conclusion:For elderly patients with HFrEF,using Aatorvastatin on the basis of conventional anti-heart failure treatment can further decrease serum TNF-α concentration and improve cardiac function and ventricular remodeling.
Objective To determine the effect of phytosternols on lowing serum lipid levels for the hypercho-lesterolemic volunteers in South China. Methods With the randomized double-blind experimental design, 141 quali-fied volunteers were assigned to four groups where a placebo and daily doses of 1.04 g, 1.56 g and 2.08 g phytosternols were respectively ingested. The t-test and one-way ANOVA were used to analyze the influences of different dose and course of phytosternols treatment. Results (1) After the intake of phytosternols, the resulted indexes of BMI, ALT and CREA have shown statistically insignificant changing trends between phytosternol groups and the control group (P>0.05). (2) After 3 months, compared with the indexes of TC and TG that have shown statistically insignificant changing trends, the LDL values of placebo, low-, mid- and high-dose groups were (3.88 ± 0.82) mmol/L, (3.06 ± 0.65) mmol/L, (3.32 ± 0.86) mmol/L and (4.26 ± 0.75) mmol/L, respectively. There was a statistically significant treatment effect on the LDL values (P<0.05). (3) The ANOVA results further indicated that the higher dose of phytosternols can facilitate the de-crease of LDL value in a shorter period. The LDL value in the low-dose group had a 13.6%of decrease for 3 months, while the LDL values of mid- and high- dose groups reduced by 18.9% and 9% respectively for 1 month's treatment. Conclusion Phytosternols can effectively decrease the LDL value in hyperlipidemia population of South China with-out affecting the liver and kidney function and body mass index.
目的:探讨冠状动脉(冠脉)粥样硬化的危险因素对心肌桥和无心肌桥患者在冠脉粥样硬化形成过程中影响的差异.方法:回顾性分析心肌桥合并冠脉粥样硬化患者78例(A组),无心肌桥的冠脉粥样硬化者73例(B组),再进一步将A组根据心肌桥在收缩期的狭窄程度分为A1组和A2组,比较A组与B组、A1组与A2组的冠脉粥样硬化危险因素的差异.结果:A与B组、A1与A2组在年龄、胸痛、BMI等方面差异无统计学意义.A与B组在餐后2h血糖、低密度脂蛋白等方面差异有统计学意义(P<0.05);A1与A2组在收缩压、低密度脂蛋白等方面差异有统计学意义(P<0.05).结论:心肌桥者因其特殊结构而较无心肌桥者更易受危险因素的影响而形成冠脉粥样硬化,更早干预和更严格控制心肌桥者的危险因素可能有利于预防和延缓冠脉粥样硬化的形成和进展.收缩期狭窄率越重其所需形成粥样硬化的危险因素越少,心肌桥收缩期狭窄程度可能是粥样硬化过程中重要的影响因素.
