5.The role of reactive oxygen species in the hyperdynamic circulation of cirrhotic portal hypertension
Chinese Journal of Hepatobiliary Surgery 2013;(4):316-320
Oxidative stress is involved in cirrhotic portal hypertension and a close relationship exists between oxidative stress and hyperdynamic circulation.This article elaborates on the function of various reactive oxygen species (e.g.,superoxide anion and hydrogen peroxide) and corresponding anti-oxidants (e.g.,NAD(P) H oxidase inhibitor,the scavengers of superoxide anion,hydrogen peroxide,and vitamin C or E) on the occurrence and development of hyperdynamic circulation in cirrhotic portal hypertension.We observed that the level of reactive oxygen species in cirrhotic portal hypertension was elevated over normal.The potential clinical value is that inhibition or removal of these reactive oxygen species can relieve hyperdynamic circulation and reduce complications for cirrhotic portal hypertension.
6.The change and its clinical significance of deceleration capacity of heart rate in elderly coronary artery disease
Chinese Journal of Geriatrics 2013;32(8):833-835
Objective To investigate the change and its clinical significance of the deceleration capacity (DC) of heart rate in elderly patients with coronary heart disease (CHD).Methods A total of 105 elderly CHD patients and 86 elderly non-CHD patients were selected.All patients underwent 24 h ambulatory electrocardiographic recording.DC,heart rate variability (HRV) time domain index,heart rate turbulence (HRT) parameters including turbulence onset (TO) and turbulence slope (TS),and the occurrence of ventricular arrhythmias were off-line calculated.Results The values of DC,HRV and HRT were decreased in elderly patients with CHD.DC had positive correlations with standard deviation of normal-to-normal intervals (SDNN),the square root of the mean squared successive differences between normal-to-normal RR intervals (rMSSD) and percentage of adjacent normal-to-normal intervals that differed more than 50 ms (pNN50) (r=0.60,0.51,0.49,0.41,respectively,all P <0.05) and had a negative correlation with the occurrence of ventricular arrhythmias (r=-0.34,P<0.05).The value of DC was much decreased in elderly CHD patients with type 2 diabetic or acute myocardial infarction.Conclusions The decreased DC value is correlated with heart rate variability,turbulence slope and the occurrence of ventricular arrhythmias in elderly CHD patients.The deceleration capacity of heart rate is a better noninvasive method for screening and predicting sudden death in high-risk elderly patients with CHD.

Fudan University Journal of Medical Sciences 2009;36(6):768-775
Objective To establish a human umbilical artery EC-SMC co-culture model, and mimic the morphological and functional characteristics of human arterial wall, for further reseach of the pathological mechanism and therapy of atherosclerosis and imflammatory damage. Methods We secceeded in the primary culture of human umbilical artery endothelial cells (HUAEC) and human umbilical artery smooth muscle cells (HUASMC) by collagenase perfusion digestion and tissue planting, respectively. HUASMCs were incubated in a medium with ascorbic acid at the concentration greater than 50 μg/mL to produce collagen, which was considered as the extracellular matrix for ECs. Then HUAECs were seeded directly upon HUASMCs in a saturate density for sufficient direct physical interaction between ECs and SMCs. The morphological characteristic of EC-SMC co-culture was identified by immunofluorescence staining, and the function of EC-SMC co-culture was identified by Dil-Ac-LDL uptake test. Results The morphological identification showed that the entire surface of HUASMCs was covered by a confluent monolayer confluent monolayer, which indicated that the model had simulated the morphological characteristic of human arterial wall. The results of Dil-Ac-LDL uptake test showed that there was a fluorescent signal in HUAECs. Compared with EC monoculture, the Dil-Ac-LDL uptake of HUAECs was increased significantly in the co-culture system. All the reseach results indicated that there was an interaction between HUAECs and HUASMCs in the co-culture system. Conclusions In the present study, human umbilical artery EC-SMC co-culture model was constructed successfully, which could mimic the morphological characteristic and basic functions of human arterial wall.
