Objective: Our aim was to evaluate effects of magnesium sulfate(MgSO4) on pulmonary hypertension in patients with chronic pulmonary heart disease(CPHD). Methods: Eight patients with CPHD undergone right-heart catheterization. The parameters of hemodynamics and arterial blood gases in patients were measured before and after MgSO4 intravenous infusion(2% MgSO4,40 mg/min). Results: Mean pulmonary artery pressure(mPAP), pulmonary vascular resistance(PVR),mean systemic artery pressure(mSAP), and total systemic vascular resistance(TSVR) significantly decreased(P＜0.05) at 30 minutes after MgSO4 infusion. The decreased percentage of mPAP and PVR at 60 minute after MgSO4 infusion was 13.37% and 18.70% respectively(P＜0.05), but mSAP and TPVR decreased only by 8.15% and 7.43% respectively. The decreased degree of mPAP and PVR at 60 minutes after MgSO4 infusion significantly correlated with mPAP(r=0.712, P＜0.05)and PVR(r=0.802, P＜0.01) before MgSO4 infusion. No unfavorable effect of MgSO4 on other parameters of hemodynamics and arterial blood gases was found. Conclusion: Magnesium sulfate can attenuate pulmonary hypertension in patients with CPHD but may cause transient systemic hypotension.

Objective: Our aim was to study the effect of endothelin-1 (ET-1) on the development of chronic hypoxic pulmonary hypertension and mechanism of QF-8 (the extract of baihua qianhu, a Chinese traditional medicine) in lowering pulmonary hypertension. Methods: The indexes of hemodynamics and the levels of plasma ET-1 in systemic vein, pulmonary artery, and systemic artery in 11 patients with pulmonary hypertension secondary to chronic obstructive pulmonary disease (COPD) were measured with right-heart catheterization and radioimmunoassay. Results: The ET-1 level in patients was significantly higher in systemic vein than that in 15 controls (P<0.01), pulmonary artery (P<0.05), and systemic artery (P<0.01). The levels of plasma ET-1 in patients had significant negative correlation with PaO2 and positive correlation with pulmonary vascular resistance index (PVRI). After taking QF-8, mean pulmonary artery pressure (mPAP) and PVRI significantly decreased, meanwhile, the levels of plasma ET-1 in systemic vein, pulmonary artery, and systemic artery also decreased by 25%, 21%, and 10%, respectively. Conclusion: Abnormality in synthesis or secretion of ET-1 may play a role in the development of chronic hypoxic pulmonary hypertension. The effect of QF-8 on pulmonary hypertension in patients with COPD may be related with its inhibition on the synthesis or secretion of ET-1.

OBJECTIVE:To study the apoptosis of human leukemic cells induced by Dihydroartemisinin and its molecular mechanism.METHODS:Human leukemia K562 cells were treated by Dihydroartemisinin.The inhibitory effect on cell proliferation was assayed by MTT.Fluorescence microscopy was applied to observe the presence of apoptosis.The expression of caspase-3 was assayed with reverse transcription-polymerase chain reaction(RT-PCR).Levels of mitochondrial and cytoplasmic cytochrome C were determined using Western blot.RESULTS:After treatment with Dihydroartemisinin for 48 hours,the IC50 values of human leukemia K562 cells were 8? 10-5mol? L-1 detected at a wavelength of 570nm by MTT.Distinct morphology changes of cell apoptosis such as karyopyknosis and conglomeration were observed by Hoechst33342/PI staining.RT-PCR assay showed the expression of Caspase-3.Western-blot detection showed the decrease of mitochondrial cytochrome C concentration but the positive expression of cytoplasmic cytochrome C concentration.CONCLUSION:Dihydroartemisinin could inhibit proliferation and induce apoptosis of human leakemic K562 cells,this may partially attributed to the promotion of the delivery of cyt-c and the activation of caspase-3.

Objectives To analyze and compare the clinical features of autonomic nervous mediated syncope (NMS) and pseudo psychogenic syncope (PPS) in children.Methods Clinical features were retrospectively analyzed in children with syncope complaint not caused by cardiac syncope, situation of syncope, drug-induced syncope, and neurogenic and metabolic diseases that caused brief loss of consciousness, and the clinical features of similarities and differences between NMS and PPS were compared. Results In 106 children with syncope were included, there were 85 cases (80.2%) of NMS, 13 cases (12.3%) of PPS, and 8 cases (7.5%) of unexplained syncope. PPS was induced by recent mental stimulation; the syncope was more frequent; the score of orthostatic intolerance was higher; the omen was rare; the duration of attack was longer. NMS was induced by long time standing, movement and body position change; the omen was mainly dizziness, blurred vision and gastrointestinal symptoms; the duration of attack was short (<5 min).Conclusions NMS is the most common cause of syncope in children, while PPS is an important cause of transient consciousness of non-syncope. There are similarities in clinical features between NMA and PPA and differential diagnosis is needed.
