摘要： The recent development of 2-dimensional strain (2D strain) imaging can provide a powerful alternative for assessing left ventricular (LV) torsion. This study was conducted to evaluate the global and regional left ventricular twist by 2D strain in patients with anterior wall myocardial infarction (AMI). A total of 55 AMI patients were divided into two groups according to their ejection fraction (EF) values (group A: LVEF≥50%; group B: LVEF<50%), and 35 normal people served as the control group. Using 2-dimensional strain software, global and regional LV rotation and displacement were obtained at two planes. Compared with the control group, patients of group A showed reduced peak LV twist of the anterior and anterior-septal wall (9.26±1.89 10.74±2.67; 9.71±1.71 11.36±2.29, both <0.05), but the radial displacement and global twist were maintained (>0.05). Differently, regional and global LV twist and radial displacement in patients of group B deceased significantly, especially in the anterior and anterior-septal wall, as compared with patients in the control or group A (both <0.05). Moreover, a strong correlation was noted between peak twist and radial displacement; the twist-displacement loop was markedly distorted in patients of group B. This study demonstrated that 2D strain has a potential ability for quantification of left ventricular global and segment twist and radial displacement in patients with coronary artery disease.

《医学前沿（英文）》 2021年 第15卷 第1期   页码 70-78 doi: 10.1007/s11684-020-0749-x

摘要： Recent studies have shown that acute blood glucose elevation in patients with ST-segment elevation myocardial infarction (STEMI) suggests a poor prognosis. To investigate the effect of fasting blood glucose (FBG) on the risk of heart failure (HF) and left ventricular systolic dysfunction (LVSD) in non-diabetic patients undergoing primary percutaneous coronary intervention (PCI) for acute STEMI, we retrospectively recruited consecutive non-diabetic patients who underwent primary PCI for STEMI in our hospital from February 2003 to March 2015. The patients were divided into two groups according to the FBG level. A total of 623 patients were recruited with an age of 61.3±12.9 years, of whom 514 (82.5%) were male. The HF risk (odds ratio 3.401, 95% confidence interval (CI) 2.144–5.395, <0.001) was significantly increased in patients with elevated FBG than those with normal FBG. Elevated FBG was also independently related to LVSD (β 1.513, 95%CI 1.282–1.785, <0.001) in a multiple logistics regression analysis. In conclusion, elevated FBG was independently associated with 30-day HF and LVSD risk in non-diabetic patients undergoing primary PCI for STEMI.

摘要： Detection of abnormal myocardial perfusion is crucial to the prognosis of patients with coronary artery disease (CAD) after they have undergone percutaneous coronary intervention (PCI). The objective of this study is to evaluate the effect of myocardial perfusion by three different methods intra-coronary myocardial contrast echocardiography (ICMCE), corrected thrombolysis in myocardial infarction frame count (CTFC), and coronary blood flow velocity (BFV) and to determine the value of these different methods in the evaluation of the effect of myocardial perfusion post-PCI. For the study sixty-eight patients were divided into four groups based on selective coronary angiography results: group A (normal coronary artery), group B (75% 95% coronary artery stenosis), group C (coronary artery stenosis >95%) and group D (acute total coronary occlusion). The effect of myocardial reperfusion was evaluated using the above mentioned three methods 15 min after PCI. IC-MCE was also performed before PCI in group D. The quantitative parameters of MCE involved: contrast peak intensity, time to peak intensity and area under the curve, representing myocardial blood volume, reperfusion velocity and myocardial blood flow, respectively. No difference was found in CTFC between the coronary artery stenosis group and the normal group. BFV was slower in group D than in group A (<0.05). The myocardial blood volume and the myocardial blood flow of the IC-MCE quantitative parameters were markedly lower in group C compared with those in group A (<0.05), and there were significant differences in the three MCE parameters between group D and group A (<0.05). For those patients with acute or total occlusion, the levels of myocardial perfusion before and after PCI were similar, as determined by IC-MCE and visually analyzed from 61 segments (<0.05). Quantitative IC-MCE evaluation of myocardial reperfusion is more accurate than with the other two methods. Moreover, with qualitative IC-MCE the level of myocardial reperfusion can be viewed directly and rapidly. Thus, the IC-MCE method is of great value to coronary artery disease (CAD) patients undergoing PCI, especially for those with acute myocardial infarction (AMI).

Enyuan TU MD, Yongjun PAN MM, Kang ZHENG MM, Zhaohua WANG MD, Qiansheng LIANG MD, Guangtian YANG MD,

《医学前沿（英文）》 2009年 第3卷 第4期   页码 431-436 doi: 10.1007/s11684-009-0088-4

摘要： The effects of tanshinone II A on cell signal transduction system protein kinase B in rats with myocardial hypertrophy induced by the abdominal aorta partial coarctation were investigated. Rat models of myocardial hypertrophy were established by using abdominal aorta partial coarctation method. Forty-eight rats were randomly divided into sham group (S group), model group (M group), valsartan treatment group (X group), low-dose tanshinone treatment group (LD group), medium-dose tanshinone treatment group (MD group), and high-dose tanshinone treatment group (HD group) (=8 in each group). Left ventricular mass index (LVMI), left ventricular posterior wall (LVPW), and septal thickness (IVS) were detected by high frequency ultrasonography. Myocardial fiber diameter (MFD) was examined by Hematoxylin-Eosin (HE) staining, and the contents of phosphorylated protein kinase B (p-Akt) and p-Gsk3β in myocardium were assayed by Western blot. The results showed that compared with S group, the values of LVMI, LVPW, IVS and MFD were increased in other groups (<0.05), and the contents of p-Akt, and p-Gsk3β were also increased in other groups. As compared with MD group, the values of LVMI, LVPW, IVS and MFD were decreased in all treatment groups (<0.05), and the contents of p-Akt, and p-Gsk3β were also decreased in all treatment groups. However, there were no significant differences among LD, MD, and HD groups (>0.05), and there were no significant differences between X group and tanshinone treatment groups (>0.05). It was suggested that tanshinone II A could prevent myocardial hypertrophy by its action on the Akt signaling pathway.

Stroke prevention: an update

《医学前沿（英文）》 2012年 第6卷 第1期   页码 22-34 doi: 10.1007/s11684-012-0178-6

摘要：

Stroke is a personal, familial, and social disaster. It is the third cause of death worldwide, the first cause of acquired disability, the second cause of dementia, and its cost is astronomic. The burden of stroke is likely to increase given the aging of the population and the growing incidence of many vascular risk factors. Prevention of stroke includes—as for all other diseases—a “mass approach” aiming at decreasing the risk at the society level and an individual approach, aiming at reducing the risk in a given subject. The mass approach is primarily based on the identification and treatment of vascular risk factors and, if possible, in the implementation of protective factors. These measures are the basis of primary prevention but most of them have now been shown to be also effective in secondary prevention. The individual approach combines a vascular risk factor modification and various treatments addressing the specific subtypes of stroke, such as antiplatelet drugs for the prevention of cerebral infarction in large and small artery diseases of the brain, carotid endarterectomy or stenting for tight carotid artery stenosis, and oral anticoagulants for the prevention of cardiac emboli. There is a growing awareness of the huge evidence-to-practice gap that exists in stroke prevention largely due to socio-economic factors. Recent approaches include low cost intervention packages to reduce blood pressure and cheap “polypills” combining in a single tablet aspirin and several drugs to lower blood pressure and cholesterol. Polypill intake should however not lead to abandon the healthy life-style measures which remain the mainstay of stroke prevention.

Miao LIU, Xiaoyan WU, Jiawei XU, Runming JIN

《医学前沿（英文）》 2009年 第3卷 第1期   页码 61-66 doi: 10.1007/s11684-009-0007-8

摘要： The aim of this study was to explore the regulatory mechanism of retinoic acid (RA) on the TBX1 gene expression in myocardial cells. Ventricular cardiocytes were isolated from neonatal rats and cultured, and then treated with different concentrations of retinoic acid. The expression of Shh and Fgf8 at mRNA and protein levels in neonatal rat myocardial cells were measured by using RT-PCR and Western blot technique, respectively. There was basal expression of Shh and Fgf8 in the control group. When treated with 3×10 mol/L RA, we observed that the expression of Shh mRNA and protein in neonatal rat myocardial cells were up-regulated by 1.51 ( <0.05) and 1.10 times ( <0.05), respectively. In comparison with the control group, under the concentration of 5×10 mol/L RA, they were up-regulated by 2.21 ( <0.05) and 2.38 times ( <0.05) individually. Meanwhile, we could detect that the expression of Fgf8 mRNA and protein were up-regulated by 2.50 times ( <0.05) and 80% ( <0.05) separately compared with the control group after stimulation of 3×10 mol/L RA, and they were up-regulated by 3.48 ( <0.05) and 2.04 times ( <0.05) individually after stimulation of 5×10 mol/L RA. The results indicated that RA could induce the expression of Shh and Fgf8 in neonatal rat myocardial cells. At the same time, it has shown that Shh and Fgf8 were involved in the regulation process of RA on TBX1 expression.

Buxu Tongyu Granule Alleviates Myocardial Ischemia by Activating Vascular Smooth Muscle Cell Soluble

摘要： Myocardial ischemia is a serious threat to human health, and vascular dysfunction is its main cause. Buxu Tongyu Granule (BXTY) is an effective traditional Chinese medicine (TCM) for treating myocardial ischemia. However, the underlying mechanism of BXTY is still unclear. In this study, we demonstrate that BXTY ameliorates myocardial ischemia by activating the soluble guanylate cyclase (sGC)–3′,5′-cyclic guanosine monophosphate (cGMP)–protein kinase G (PKG) signaling pathway in vascular smooth muscle cells (VSMCs) to dilate the arteries. BXTY was given by gavage for ten consecutive days before establishing an animal model of acute myocardial ischemia in mice via the intraperitoneal injection of pituitrin. The results showed that BXTY alleviated the symptoms of myocardial ischemia induced by pituitrin in mice, including electrocardiogram abnormalities and changes in plasma enzymes. In addition, BXTY dilated pre-constricted blood vessels and inhibited the vasoconstriction of the superior mesenteric artery in a dose-dependent but endothelial-independent manner. These effects were eliminated by pre-incubating vascular rings with the sGC inhibitors NS 2028 or ODQ, or with the PKG inhibitor KT 5823. Moreover, BXTY increased the protein expression of sGC-β1 and the intracellular second messenger cGMP level in mouse aortic vascular smooth muscle cells (MOVAs). NS 2028 or ODQ reversed these effects of BXTY. The expression level of the cGMP downstream effector protein PKG-1 increased after treating MOVAs with BXTY. NS 2028, ODQ, or KT 5823 also reversed this effect of BXTY. In conclusion, BXTY can improve the symptoms of acute myocardial ischemia in mice, and activating the sGC–cGMP–PKG pathway in VSMCs to induce vasodilation is its key pharmacodynamic mechanism.

Challenges and opportunities in improving left ventricular remodelling and clinical outcome following surgical and trans-catheter aortic valve replacement

《医学前沿（英文）》 2021年 第15卷 第3期   页码 416-437 doi: 10.1007/s11684-021-0852-7

摘要： Over the last half century, surgical aortic valve replacement (SAVR) has evolved to offer a durable and efficient valve haemodynamically, with low procedural complications that allows favourable remodelling of left ventricular (LV) structure and function. The latter has become more challenging among elderly patients, particularly following trans-catheter aortic valve implantation (TAVI). Precise understanding of myocardial adaptation to pressure and volume overloading and its responses to valve surgery requires comprehensive assessments from aortic valve energy loss, valvular-vascular impedance to myocardial activation, force-velocity relationship, and myocardial strain. LV hypertrophy and myocardial fibrosis remains as the structural and morphological focus in this endeavour. Early intervention in asymptomatic aortic stenosis or regurgitation along with individualised management of hypertension and atrial fibrillation is likely to improve patient outcome. Physiological pacing via the His-Purkinje system for conduction abnormalities, further reduction in para-valvular aortic regurgitation along with therapy of angiotensin receptor blockade will improve patient outcome by facilitating hypertrophy regression, LV coordinate contraction, and global vascular function. TAVI leaflet thromboses require anticoagulation while impaired access to coronary ostia risks future TAVI-in-TAVI or coronary interventions. Until comparable long-term durability and the resolution of TAVI related complications become available, SAVR remains the first choice for lower risk younger patients.
