The effect of astaxanthin on N(Ω)-nitro-L-arginine methyl ester (L-NAME) induced preeclampsia disease rats was investigated. Thirty pregnant Sprague-Dawley rats were randomly divided into three groups (n = 10): blank group, L-NAME group and astaxanthin group. From day 5 to 20, astaxanthin group rats were treated with astaxanthin (25 mg x kg(-1) x d(-1) x bw(-1)) from pregnancy (day 5). To establish the preeclamptic rat model, L-NAME group and astaxanthin group rats were injected with L-NAME (125 mg x kg(-1) x d(-1) x bw(-1)) from days 10-20 of pregnancy. The blood pressure and urine protein were recorded. Serum of each group was collected and malondialdehyde (MDA), superoxide dismutase (SOD) and nitric oxide synthase (NOS) activities were analyzed. Pathological changes were observed with HE stain. The expression of NF-κB (nuclear factor kappa B), ROCK II (Rho-associated protein kinase II), HO-1 (heme oxygenase-1) and Caspase 3 were analyzed with immunohistochemistry. L-NAME induced typical preeclampsia symptoms, such as the increased blood pressure, urinary protein, the content of MDA, etc. Astaxanthin significantly reduced the blood pressure (P < 0.01), the content of MDA (P < 0.05), and increased the activity of SOD (P < 0.05) of preeclampsia rats. The urinary protein, NO, and NOS were also decreased. HE stain revealed that after treated with astaxanthin, the thickness of basilal membrane was improved and the content of trophoblast cells and spiral arteries was reduced. Immunohistochemistry results revealed that the expressions of NF-κB, ROCK II and Caspase 3 in placenta tissue were effectively decreased, and HO-1 was increased. Results indicated that astaxanthin can improve the preeclampsia symptoms by effectively reducing the oxidative stress and inflammatory damages of preeclampsia. It revealed that astaxanthin may be benefit for prevention and treatment of preeclampsia disease.

Objective To investigate the impact of optical coherence tomography(OCT) imaging on physician decision-making during primary percutaneous coronary intervention(PCI) in patients with ST-segment elevation myocardial infarction (STEMI). Methods From January 2016 to May 2017, OCT was performed in 100 cases pre- and post- primary PCI. The pathogenesis of myocardial infarction was determined and immediate effect of PCI evaluated by OCT. Clinical outcome during a 12-months follow up was analyzed. Results The data from 17 patients were excluded for further study due to poor OCT images quality. The rates of plaque rupture, plaque erosion, calcification nodules, stent malapposition and coronary spasm were 65.1%(54/83), 26.5%(22/83), 3.6%(3/83), 2.4%(2/83) respectively among the remaining 83 patients with sufficient OCT quality images. of the overall rate of stent malposition, tissue prolapse and incomplete stent expansion was 21.7%(18/83). The incidence of edge dissection was 19.3%(16/83), and among them 2 patients required treatment with stent implantation. Among the 17 patients without stenting:coronary spasm were found in 2 cases, thrombus overload in 1 case after thrombus aspiration, plaque rupture in 7 cases , plaque erosion in 4 cases and stent malposition in 3 cases. One patient died in hospital for cardiogenic shock and one patient had subacute stent thrombosis . There were no major adverse cardiac events occurred in the remaining patients during the (11.0±4.0) months of follow-up. Conclusions OCT can identify nonoptimal stent deployment in approximately one-fourth of STEMI patients undergoing primary PCI, thus providing preliminary guidance to the physician for further mangement.
