The effects of Dimethyl trilobine Iodide (DTI) on the blood lipids and lipoprotein choieslerol of rats and hemorrheology of rabbits were studied An peritoneal injection of DTI at the dosage of 0.5mg/kg could increase the serum TG of normal rais and reduce the HDL-c and HDL-c/LDL-c of rats fed with normal and fat-rich diets. An intravenous injection of DTI at the dosage of 10?g/kg accelerated formation of thrombus in vitro and at 5?g/kg and 10?g/kg elevated plasma mucosity at high sheafing. It was demonstrated that DTI had probably unfavorable effects on mediation of blood lipids of rats and hemorrheology of rabbits.

Objective: To investigate the association between hyponatremia and hemodynamic and prognosis in patients with intermediate-risk acute pulmonary embolism. Methods: We retrospectively recruited 110 intermediate-risk acute pulmonary embolism patients (right ventricular dysfunction was confirmed by echocardiography and CT scan with or without the elevated levels of cardiac injury biomarkers) in the first and the second affiliated hospital of Harbin medical university from January 1,2011 to December 31, 2014. The patients were aged (58.4±14.9) years old.There were 49 males and 61 females.Patients were divided into 2 groups as non-hyponatremia group (plasma sodium>135 mmol/L, 93 cases) and hyponatremia group (plasma sodium≤135 mmol/L, 17 cases). Baseline clinical and hemodynamic parameters were obtained from these patients. All enrolled patients were followed up after discharge. Results: Heart rate ((106.7±21.9) beats per minute vs. (93.4±19.4) beats per minute, P=0.043),N-terminal pro B type natriuretic peptide (NT-proBNP, (5 561±1 593) ng/L vs. (1 738±589) ng/L, P=0.005), mean pulmonary arterial pressure((42.6±12.6)mmHg(1 mmHg=0.133 kPa) vs. (33.9±13.3)mmHg, P=0.046), mean right atria pressure ((20.6±8.1)mmHg vs. (10.2±5.4)mmHg, P=0.014), systolic right atria pressure ((27.3±9.0)mmHg vs. (15.6±6.1)mmHg,P=0.013) and diastolic right atria pressure(6.5(4.3,15.5)mmHg vs. 5.0(2.0,8.0)mmHg,P=0.016) were significantly higher in hyponatremia group than in non-hyponatremia group,and systolic blood pressure was significantly lower in hyponatremia group than in non-hyponatremia group ((113.5±21.9)mmHg vs.(129.5±28.9)mmHg, P=0.048). Pearson correlation analysis showed that hyponatremia was negatively correlated with heart rate (r=-0.262, P=0.043), NT-proBNP (r=-0.227, P=0.048), mean pulmonary arterial hypertension (r=-0.259, P=0.046), mean right ventricular pressure (r=-0.296, P=0.047), mean right atria pressure (r=-0.550, P=0.001), systolic right atria pressure (r=-0.552, P=0.001), and diastolic right atria pressure (r=-0.542, P=0.001). Kaplan-Meier survival analysis showed that the 1-year, 2-year and 3-year cumulative survival rates were 76.5%,70.6%,and 64.7% in the hyponatremia group, and 90.3%,86.0%,and 83.9% in the non-hyponatremia group(log-rank test, P=0.036).Multivariate Cox regression analysis showed that hyponatremia was an independent risk factor of death of intermediate-risk pulmonary embolism patient(HR=4.126, 95%CI 1.982-11.343, P=0.036). Conclusion Hyponatremia is associated with adverse hemodynamic and reduced survival in patients with intermediate-risk pulmonary embolism.

Aortic dissection, especially Stanford type A aortic dissection, is an acutely progressive and highly fatal cardiovascular disease.Early prevention and timely treatment can greatly reduce mortality and reduce the burden on families and society.However, due to the etiological mechanism is still unclear, the clinical treatment is still mainly surgery, and the early prevention and drug application are very limited.And some recent studies have found that ferroptosis may play an important role in the occurrence and development of aortic dissection, revealing the relationship between them may provide ideas for the prevention, treatment and scientific research of the disease.

Objective:To investigate the effect of monosialotetrahexosylganglioside sodium treatment on neurological function, inflammatory factor, and blood coagulation function in patients with traumatic brain injury.Methods:The clinical data of 90 patients with traumatic brain injury who received treatment in Taizhou Central Hospital from February 2018 to May 2020 were retrospectively analyzed.

Objective:To explore the application value of a novel ultrasonic scale in the evaluation of sub-massive pulmonary embolism (sub-PE).Methods:Retrospective analyses were conducted in 137 patients with acute pulmonary embolism confirmed by computed tomography pulmonary angiography (CTPA) in the second affiliated hospital of Harbin Medical University from September 2017 to June 2019. They were divided into experimental set (77 cases) and testing set(60 cases). According to the European Society of Cardiology (ESC) guidelines for pulmonary embolism in 2019, the patients were classified into sub-PE(71 cases) and small pulmonary embolism(small-PE, 66 cases). Parameters in the experimental set were screened by statistical methods to make an ultrasonic scale, and then the patients in the testing set were scored by the scale. ROC curve was plotted to calculate the diagnostic efficacy of the ultrasonic scale for sub-PE.Results:①The patients of sub-PE were older than small-PE patients [(61.57±1.45) years vs (56.31±1.59) years, P=0.016], but there was no significant difference between the two groups in other general data( P>0.05). ②Within the 77 pulmonary embolism patients in the experimental set, 41(53.25%) were classified as the sub-PE and 36(46.75%) as the small-PE. Compared with the small-PE group, right ventricular diameter, pulmonary artery trunk diameter, right ventricle/left ventricle ratio, tricuspid regurgitation velocity, the Tei index and the inferior vena cava diameter in the sub-PE group increased significantly ( P<0.05), and right ventricular wall motion amplitude, right atrium area rate, right ventricular area rate, tricuspid annulus systolic displacement, collapse rate of inferior vena cava and pulmonary artery blood flow acceleration time decreased significantly ( P<0.05); ③Fifteen ultrasonic parameters were used in the ultrasonic scale. The scale in sub-PE group of the testing set was significantly increased compared with that in small-PE group (11.63±3.87 vs 4.43±1.96, P<0.001). ROC showed that the AUC in diagnosing sub-PE by ultrasonic scale was 0.96. When the cut-off value was 6.5, the sensitivity and specificity were 90.00% and 83.33%, respectively. Conclusions:The novel ultrasonic scale can provide a comprehensive and feasible ultrasound imaging method for evaluation of sub-PE.

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in childhood, which seriously affects physical and mental health in children.Its etiology and pathogenesis are complex and have not been fully elucidated.Currently, the theory of Dopamine (DA) deficits has been widely recognized and studied in the international academic community.The DA system is considered as the key to the pathogenesis of ADHD.The causes of DA deficits are complex.In addition to the well-established reuptake disorder caused by abnormal DA transporter function, DA deficits are also associated with the activation of DA vesicle cycle enzymatic inactivation, vesicle transport dysfunction, and receptor dysfunction, which are of great significance in analyzing disease pathogenesis and drug development.This article reviews the research on the causes of DA deficits proposed in recent years based on the theory of DA deficits, aiming to provide ideas and references for the research on the pathogenesis of ADHD in China.

Background::The potential impact of pre-existing coronary artery stenosis (CAS) on acute pulmonary embolism (PE) episodes remains underexplored. This study aimed to investigate the association between pre-existing CAS and the elevation of high-sensitivity cardiac troponin I (hs-cTnI) levels in patients with PE.Methods::In this multicenter, prospective case-control study, 88 cases and 163 controls matched for age, sex, and study center were enrolled. Cases were patients with PE with elevated hs-cTnI. Controls were patients with PE with normal hs-cTnI. Coronary artery assessment utilized coronary computed tomographic angiography or invasive coronary angiography. CAS was defined as ≥50% stenosis of the lumen diameter in any coronary vessel >2.0 mm in diameter. Conditional logistic regression was used to evaluate the association between CAS and hs-cTnI elevation.Results::The percentage of CAS was higher in the case group compared to the control group (44.3% [39/88] vs. 30.1% [49/163]; P = 0.024). In multivariable conditional logistic regression model 1, CAS (adjusted odds ratio [OR], 2.680; 95% confidence interval [CI], 1.243–5.779), heart rate >75 beats/min (OR, 2.306; 95% CI, 1.056–5.036) and N-terminal pro-B type natriuretic peptide (NT-proBNP) >420 pg/mL (OR, 12.169; 95% CI, 4.792–30.900) were independently associated with elevated hs-cTnI. In model 2, right CAS (OR, 3.615; 95% CI, 1.467–8.909) and NT-proBNP >420 pg/mL (OR, 13.890; 95% CI, 5.288–36.484) were independently associated with elevated hs-cTnI. Conclusions::CAS was independently associated with myocardial injury in patients with PE. Vigilance towards CAS is warranted in patients with PE with elevated cardiac troponin levels.
