OBJECTIVE: To study the effects of 3, 4-di-O-methyl-1, 2, 5, 6-D-mannitol tetranitrate(DMMTN) on acute myocardial ischemia induced by ligating coronary artery in rats. METHODS: Acute myocardial ischemia model was developed by ligating the anterior descending branch of left coronary artery in rats. The rats were randomly divided into 6 groups: sham group, model group, Lunanxinkang group, low-dose (15 mg · kg-1) DMMTN group, middle-dose (30 mg · kg-1) DMMTN group and high-dose (60 mg · kg-1) DMMTN group. The changes of ST segment and T segment of electrocardiogram at different moment were recorded after myocardial ischemia injury. At 3 h after ligation, the myocardial infarct size was measured by nitroblue tetrazolium (NBT) staining method. And the activities of creatine phosphokinase (CK), lactate dehydrogenase (LDH) and superoxide dismutase (SOD), and the content of malondialdehyde (MDA) were determined to evaluate the protective effects of DMMTN. RESULTS: DMMTN could reduce the size of myocardial infarct significantly, inhibit the rising of ST segment and T segment of electrocardiogram, decrease the level of CK, LDH and MDA, and increase the activity of SOD. CONCLUSION: DMMTN showed obvious protective effects on acute myocardial ischemia induced by ligating the coronary artery in rats. Copyright 2012 by the Chinese Pharmaceutical Association.

In this study, a closed-loop controller for chest compression which adjusts chest compression depth according to the coronary perfusion pressure (CPP) was proposed. An effective and personalized chest compression method for automatic mechanical compression devices was provided, and the traditional and uniform chest compression standard neglecting individual difference was improved. This study rebuilds Charles F. Babbs human circulation model with CPP simulation module and proposes a closed-loop controller based on a fuzzy control algorithm. The performance of the fuzzy controller was evaluated and compared to that of a traditional PID controller in computer simulation studies. The simulation results demonstrated that the fuzzy closed-loop controller produced shorter regulation time, fewer oscillations and smaller overshoot than those of the traditional PID controller and outperforms the traditional PID controller in CPP regulation and maintenance.

Objective:To provide clinical data for early identification and diagnosis of vascular embolism in children.Methods:We collected and analyzed the clinical data of children with vascular embolism diagnosed at the Children Medical Center of the First Affiliated Hospital of Hunan Normal University from January 2017 to January 2020.Results:A total of 29 children with vascular embolism were included.The male to female ratio was 2.2∶1(20/9); the age range was 1 month to 13 years, and the median age(IQR) was 16 (6-41)months.Among them, 22 cases were diagnosed with venous thrombosis, including 13 children with lower limb venous thrombosis(13/29, 44.8%), and six children with intracranial venous thrombosis(6/29, 20.7%). Arterial embolism was found in six cases, and left atrial appendage thrombosis was found in one case.Severe pneumonia was the most common primary disease(19/29, 65.5%), followed by cardiopulmonary resuscitation(3/29, 10.3%), and Kawasaki disease(3/29, 10.3%). Analysis on the risk factors of vascular embolization diseases, including catheter-related, long-term bed rest, elevated D-dimer, mechanical ventilation, and intravenous hormone administration, showed that 89.2%(25/29)had ≥3 risk factors at the same time, and 82.8%(24/29)had ≥5 risk factors at the same time.Conclusion:In children with vascular thrombotic diseases, deep venous thrombosis, especially lower extremity venous thrombosis, are common.The severe pneumonia is more common in primary disease.Children with multiple risk factors have a higher risk of developing vascular embolism.In clinic, coagulation function should be monitored and local symptoms should be observed for early identification.

BACKGROUND: As a reliable marker of inflammation, intercellular adhesion molecule-1 (ICAM-1) plays an important role in atherogenesis. Recently, it is assumed in researches of recent years that chronic inflammation mediated by ICAM-1 is involved in hypertensive left ventricular hypertrophy probably, but there are still some objections reported. Tanshinone ⅡA is a kind of liposoluble extract from danshen(Radix Salviae Mitiorrhizae) . It is verified in animal experiment that it can inhibit hypertensive left ventricular hypertrophy.OBJECTIVE: To investigate the relationship between ICAM-1 and hypertensive left ventricular hypertrophy and the effect of tanshinone ⅡA on expression of ICAM-1.DESIGN:A randomized controlled observation was designed.SETTING: Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology.MATERIALS: The experiment was performed in the Laboratory of Emergency Department of Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from October 2002 to January 2004. Ten male WKY rats(10 WKY rats) of 12-week-old and 20 rats with spontaneous hypertension(20 SHR rats) were employed and divided into the control group(10 WKY rats), hypertension group(10 SHR rats) and tanshinone ⅡA group(10 SHR rats).injected from caudal vein for treatment and distilled water at the same dose was injected in the other two groups. Twelve weeks later, the rats were sacrificed and myocardium was collected for specimen preparation. Haematoxylin and eosin(HE) staining, VG staining, immunocytochemical staining and myocardial ED1 labeling were applied to determine myocardial macrophage infiltration degree. The reverse transcription-polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay(ELISA) were used to determine the expressions of ICAM-1 mRNA and protein.MAIN OUTCOME MEASURES: Degree of macrophages infiltration and the expressions of ICAM-1 mRNA and protein in myocardium in each group.RESULTS: Twelve SHR and 10 WKY rats were employed in the experiment pared with the control group, ICAM-1 mRNA and protein expressions in hypertrophic myocardium were increased significantly in hypertension group (0.176±0.087,0.537±0.195;0.104±0.011,0.173±0.027, P ＜0.01or P ＜ 0.05) . Infiltration of macrophage was significant(0. 62 ±0.07,non Ⅱ A group, the expressions of ICAM-1 mRNA and protein were decreased significantly(0. 537 ±0. 195, 0.291 ±0. 106; 0. 173 ±0.027, 0. 125± 0. 014, P ＜ 0.01 or P ＜ 0. 05); the amount of macrophages infiltration was decreased(1.85 ±0. 23, 1.16 ±0. 17, P ＜ 0.05) and the degree of cardiomyocytic hypertrophy and interstitial fibrosis was remarkably relieved.CONCLUSION: Excessive expression of myocardial ICAM-1 and its mediated inflammatory cellular infiltration plays an important role in hypertensive left ventricular hypertrophy. The inhibition of tanshinone ⅡA on left ventricular hypertrophy may be contributed to decreased expression of ICAM-1 and alleviated inflammatory cellular infiltration in myocardium.
