Malaria, one of the major global public health events, is a leading cause of mortality and morbidity among children and adults in tropical and subtropical regions(mainly in sub-Saharan Africa), threatening human health. It is well known that malaria can cause various complications including anemia, blackwater fever, cerebral malaria, and kidney damage. Conventionally, cardiac involvement has not been listed as a common reason affecting morbidity and mortality of malaria, which may be related to ignored cases or insufficient diagnosis. However, the serious clinical consequences such as acute coronary syndrome, heart failure, and malignant arrhythmia caused by malaria have aroused great concern. At present, antimalarials are commonly used for treating malaria in clinical practice. However, inappropriate medication can increase the risk of cardiovascular diseases and cause severe consequences. This review summarized the research advances in the cardiovascular complications including acute myocardial infarction, arrhythmia, hypertension, heart failure, and myocarditis in malaria. The possible mechanisms of cardiovascular diseases caused by malaria were systematically expounded from the hypotheses of cell adhesion, inflammation and cytokines, myocardial apoptosis induced by plasmodium toxin, cardiac injury secondary to acute renal failure, and thrombosis. Furthermore, the effects of quinolines, nucleoprotein synthesis inhibitors, and artemisinin and its derivatives on cardiac structure and function were summarized. Compared with the cardiac toxicity of quinolines in antimalarial therapy, the adverse effects of artemisinin-derived drugs on heart have not been reported in clinical studies. More importantly, the artemisinin-derived drugs demonstrate favorable application prospects in the prevention and treatment of cardiovascular diseases, and are expected to play a role in the treatment of malaria patients with cardiovascular diseases. This review provides reference for the prevention and treatment of malaria-related cardiovascular complications as well as the safe application of antimalarials.

Chinese Journal of Contemporary Pediatrics 2023;25(12):1198-1210
Kawasaki disease (KD) is an acute self-limiting vasculitis, and it is the most common cause of acquired heart disease in children under 5 years old. One of the improvement goals in pediatric quality control work for the year 2023, as announced by the National Health Commission, is to reduce the incidence of cardiac events and KD-related mortality in children with KD. In order to standardize the diagnosis, treatment, and long-term management practices of KD in China, and effectively prevent and reduce the incidence of coronary artery lesions and long-term adverse effects, the guideline working group followed the principles and methods outlined by the World Health Organization and referenced existing evidence and experiences to develop the "Evidence-based guidelines for the diagnosis and treatment of Kawasaki disease in children in China (2023)". The guidelines address the clinical questions regarding the classification and definition of KD, diagnosis of different types of KD, treatment during the acute phase of KD, application of echocardiography in identifying complications of KD, and management of KD combined with macrophage activation syndrome. Based on the best evidence and expert consensus, 20 recommendations were formulated, aiming to provide guidance and decision-making basis for healthcare professionals in the diagnosis and treatment of KD in children.

Arrhythmia is an external manifestation of cardiac electrophysiological disorder. It exists in healthy people and patients with various heart diseases, which is often associated with other cardiovascular diseases. The contraction and diastole of myocardium are inseparable from the movement of ions. There are many ion channels in the membrane and organelle membrane of myocardium. The dynamic balance of myocardial ions is vital in maintaining myocardial electrical homeostasis. Potassium ion channels that have a complex variety and a wide distribution are involved in the whole process of resting potential and action potential of cardiomyocytes. Potassium ion channels play a vital role in maintaining normal electrophysiological activity of myocardium and is one of the pathogenesis of arrhythmia. Traditional Chinese medicine(TCM)has unique advantages in treating arrhythmia for its complex active components and diverse targets. A large number of TCM preparations have definite effect on treating arrhythmia-related diseases, whose antiarrhythmic mechanism may be related to the effect on potassium channel. This article mainly reviewed the relevant studies on the active components in TCM acting on different potassium channels to provide references for clinical drug use and development.

Infective endocarditis in pregnancy is extremely rare in clinical practice. Guidelines addressing prophylaxis and management of infective endocarditis do not extensively deal with concomitant pregnancy, and case reports on infective endocarditis are scarce. Due to increased blood volume and hemodynamic changes in late pregnancy, endocardial neoplasms are easy to fall off and cause systemic or pulmonary embolism, respiratory, cardiac arrest and sudden death may occur in pregnant women, the fetus can suffer from intrauterine distress and stillbirth at any time, leading to adverse outcomes for pregnant women and fetuses. The disease is dangerous and difficult to treat, which seriously threatens the lives of mothers and babies. Early diagnosis and reasonable treatment can effectively improve the prognosis of patients. The most important method for the treatment of infective endocarditis requires early, adequate, long-term and combined antibiotic therapy. Moreover, surgical controversies regarding indication and timing of treatment exist, especially in pregnancy. In terms of the timing of termination of pregnancy, the timing of cardiac surgery, and the method of surgery, individualized programs must be adopted. A pregnant woman with 30+5 weeks of gestation is reported. She was admitted to hospital due to intermittent chest tightness, suffocation and fever, with grade Ⅲ cardiac insufficiency. Imaging revealed large mitral valve vegetation, 22.0 mm×4.1 mm and 22.0 mm×5.1 mm, respectively, and severe valve regurgitation. Mitral valve perforation was more likely, blood culture suggested Staphylococcus epidermidis infection, after antibiotic conservative treatment, the effect was poor. After the joint consultation including cardiology, neonatology, interventional vascular surgery, anesthesiology, and obstetrics, the combined operation of obstetrics and cardiac surgery was performed in time. The heart was blocked for 60 minutes, the bleeding was 1 200 mL, the newborn was mildly asphyxiated after birth, and the birth weight was 1 890 g. Nine days after the operation, the patient was discharged from the hospital, and the newborn was discharged with the weight of 2 020 g. Critical cases like this require a thorough weighing of risks and benefits followed by swift action to protect the mother and her unborn child. An optimal outcome in a challenging case like this greatly depends on effective interdisciplinary communication, informed consent of the patient, and concerted action among the specialists involved.

OBJECTIVE:
To evaluate the protective effects of Astragaloside IV (AST) in a rat model of myocardial injury induced by cecal ligation and puncture (CLP).
METHODS:
The model of sepsis-induced cardiac dysfunction was induced by CLP. Using a random number table, 50 specific pathogen free grade of Sprague Dawley rats were randomized into 5 groups: the sham group (sham), the model group (CLP, 18 h/72 h) and AST group (18 h/72 h). Except the sham group, the rats in other groups received CLP surgery to induce sepsis. CLP groups received intragastric administration with normal saline after CLP. AST groups received intragastric administration with AST solution (40 mg/kg) once a day. The levels of inflammatory mediators and oxidative stress markers in the serum of the septic rats were determined via enzyme-linked immunosorbent assay (ELISA) at different time point, such as interleukin 6 (IL-6), IL-10, high mobility group box-1 protein B1 (HMGB-1), superoxide dismutase (SOD), and malondialdehyde (MDA). Cardiac function was determined by echocardiography. Moreover, changes in myocardial pathology were evaluated using hematoxylin and eosin staining. The levels of lactate dehydrogenase (LDH) and creatine kinase-MB (CK-MB) were analysed to determine the status of CLP-induced myocardium. In addition, the apotosis of myocardial cells was analysed by terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL). The protein levels of B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X (Bax), IκB kinase α (IKKα), nuclear factor kappa B p65 (NF-κB p65) were detected by Western blot analysis. Moreover, survival rate was investigated.
RESULTS:
AST improved the survival rate of CLP-induced rats by up to 33.3% (P<0.05). The cardioprotective effect of AST was observed by increased ejection fraction, fractional shortening and left ventricular internal diameter in diastole respectively (P<0.01 or P<0.05). Subsequently, AST attenuated CLP-induced myocardial apoptosis and the ratio of Bcl-2/Bax in the myocardium, as well as the histological alterations of myocardium (P<0.01 or P<0.05); the generation of inflammatory cytokines (IL-6, IL-10, HMGB-1) and oxidative stress markers (SOD, MDA) in the serum was significantly alleviated (P<0.01 or P<0.05). On the other hand, AST markedly suppressed CLP-induced accumulation of IKK-α and NF-κB p65 subunit phosphorylation (P<0.01 or P<0.05).
CONCLUSIONS
AST plays a significant protective role in sepsis-induced cardiac dysfunction and survival outcome. The possible mechanism of cardioprotection is dependent on the activation of the IKK/NF-κB pathway in cardiomyocytes.

Candida vertebral osteomyelitis (CVO) is a rare disease that is a complication of intravenous drug use, but recently it has been recognized as mostly an opportunistic infection. Because CVO appears to mimic pyogenic spondylodiscitis in terms of the clinical and radiologic presentations, it is often neglected in a usual clinical setting. The clinical, radiological, and biological characteristics of CVO are often used to make a differential diagnosis with vertebral osteomyelitis from other etiologies. Once an initial proper diagnosis was performed, the treatment relies on the prompt initiation of appropriate pharmacotherapy and serial monitoring of the clinical progress. This paper report late-onset CVO in two young patients who underwent a heart transplant surgery and had postoperative systemic candidiasis. These two cases are a good reminder of the potential of CVO in immunosuppressive patients treated with anti-fungal agents. This paper presents these two cases with a review of the relevant literature.

Cream formula has been mostly used to treat deficiency syndrome. Currently,it has been used to recuperate the body,promote health against aging,and prevent and treat chronic disease. In modern medicine,there are only treatment concepts and methods of diseases,but lack of concepts of " deficiency syndrome" and " restoring deficiency". The concepts of " deficiency syndrome" and " restoring deficiency" could effectively supplement and improve the diagnosis and treatment scheme of some modern diseases. Refractory heart failure,dilated cardiomyopathy,ischemic cardiomyopathy,and valvular heart disease belong to the traditional category of " consumptive disease". The cream formula with the efficacy of restoring deficiency can not only alleviate symptoms and improve the quality of life,but also improve the structure and function of the heart,reduce the dosage of diuretics and the number of hospitalizations,and achieve the purpose of secondary prevention in the treatment of severe heart failure,dilated cardiomyopathy,ischemic cardiomyopathy and valvular heart disease. The cream formula for treating chronic heart failure include Shenqi Pills,Zhenwu Decoction,Yougui Pills,Wuling Powder,Linggui Zhugan Decoction,Danggui Shaoyao Powder,Lizhong Decoction,Buzhong Yiqi Decoction,Guipi Decoction,Yupingfeng Powder,Guizhi Decoction. Long-term administration of cream formula could not only resist aging,but also play an irreplaceable role in the secondary prevention of acute and critical diseases.
