Pre-germinated brown rice alleviates non-alcoholic fatty liver disease induced by high fructose and high fat intake in rat.

In past researches, we had been proved the action mechanism of pre-germinated brown rice (PGBR) to treat metabolic syndrome and diabetes mellitus. This study was to investigate the protective effect of PGBR in high fructose and high fat-induced non-alcoholic fatty liver disease (NAFLD) in rodents. WKY rats were divided into: Control group was fed normal drinking water and diet; FLD group was fed 10% high-fructose-water (HFW) and high-fat-diet (HFD); PGBR group was given HFW, and HFD mixed PGBR. After four weeks, the body, hepatic and cardiac weight gains of FLD group had significant increases than that of Control group. The enhanced blood pressure and heart rate, hypertriglyceridemia, hyperuricemia, and higher liver function index (GPT levels) were observed; meanwhile, the IL-6 and TNF-α levels of serum, and TG level of liver were also elevated in FLD group. The related protein expressions of lipid synthesis, inflammation, cardiac fibrosis, and hypertrophy were deteriorated by HFW/HFD. However, in treatment group, PGBR decreased all above influenced parameters, additionally GOT; and related protein expressions. PGBR treated HFW/HFD-induced NAFLD and cardiac complications might be via improving lipid homeostasis, and inhibiting inflammation. Together, PGBR could be used as a healthy food for controlling NAFLD and its' cardiac dysfunction.

Management of Pulmonary Arterial Hypertension Patients with World Health Organization Functional Class II.

Pulmonary arterial hypertension (PAH) is an incurable chronic and progressive debilitating disease associated with significant morbidity and mortality. The World Health Organization functional class (WHO FC) at diagnosis and at follow-up remains one of the strongest predictors of survival in PAH. Studies have shown improved long-term outcomes in PAH patients who received PAH-specific treatment, as monotherapy or as combination therapy, early in their disease course. Studies have also shown that without treatment, PAH rapidly deteriorates even in patients with less advanced (low risk) disease state. In this article, we review evidence from randomized controlled clinical trials to support our position on the importance of early PAH management in WHO FC II patients. The growing importance of combination therapy in the early treatment of PAH and recommendations by the most recent guidelines for the diagnosis and treatment of pulmonary hypertension are also discussed in this article.

The Effects of Ergosta-7,9(11),22-trien-3ß-ol from Antrodia camphorata on the Biochemical Profile and Exercise Performance of Mice.

Antrodia camphorata (AC) is a rare and unique mushroom that is difficult to cultivate. Previous studies have demonstrated the bioactivity of the compound Ergosta-7,9(11),22-trien-3ß-ol (EK100) from AC in submerged culture. The purpose of this study is to evaluate the potential beneficial effects of EK100 on fatigue and ergogenic functions following physiological challenge. Male ICR (Institute of Cancer Research) mice were randomly divided into three groups (n = 8 per group) and orally administered EK100 for six weeks at 0 (Vehicle), 10 (EK100-1X), and 20 (EK100-2X) mg/kg/day. The six-week Ek100 supplementation significantly increased grip strength (P = 0.0051) in trend analysis. Anti-fatigue activity was evaluated using 15-min. acute exercise testing and measuring the levels of serum lactate, ammonia, glucose, blood urea nitrogen (BUN), and creatine kinase (CK) after a 15-min. swimming exercise. Our results indicate that AC supplementation leads to a dose-dependent decrease in serum lactate, ammonia, BUN, and CK activity after exercise and significantly increases serum glucose and glycogen content in liver tissues. Biochemical and histopathological data demonstrated that long term daily administration of EK100 for over six weeks (subacute toxicity) was safe. EK100's anti-fatigue properties appear to be through the preservation of energy storage, increasing blood glucose and liver glycogen content, and decreasing the serum levels of lactate, ammonia, BUN, and CK. EK100 could potentially be used to improve exercise physiological adaptation, promote health, and as a potential ergogenic aid in combination with different nutrient strategies.

Combination Therapy with Dipyridamole and Clopidogrel for Secondary Stroke Prevention in Aspirin-Intolerant Patients After Myocardial Infarction: Results of a Nationwide Case-Control Study.

BACKGROUND AND PURPOSE: Combination therapy with dipyridamole and clopidogrel in stroke prevention and long-term outcomes in aspirin-intolerant patients with acute myocardial infarction (AMI) and previous stroke are unknown. This nationwide study analyzed the impact of dipyridamole and clopidogrel on secondary stroke prevention and long-term outcomes in aspirin-intolerant stroke patients after AMI. METHODS: This was a nationwide, case-control study involving 186,112 first AMI patients, 78,607 of whom had a previous history of stroke. In the final analysis, we included 4637 patients taking clopidogrel alone and 208 patients using a combination of clopidogrel and dipyridamole. RESULTS: The 12-year survival rate was not different between clopidogrel and clopidogrel-dipyridamole groups (log-rank p = 0.6247). Furthermore, there were no differences in event-free survival after stroke (log-rank p = 0.6842), gastrointestinal (GI) bleeding (log-rank p = 0.9539), or intracerebral hemorrhage (ICH; log-rank p = 0.6191) between the two groups. Dipyridamole did not contribute significantly to AMI survival (hazard ratio 0.98, 95% confidence interval 0.84-1.15), and did not show benefits in any of the subgroups regardless of sex, age (younger or older than 75 years), comorbidities, percutaneous coronary intervention, or medications. CONCLUSION: No differences were observed in the 12-year survival rate between clopidogrel and clopidogrel-dipyridamole groups. The two groups had balanced event-free survival in recurrent stroke, ICH, GI bleeding, and myocardial infarction.

The Dipyridamole Added to Dual Antiplatelet Therapy in Cerebral Infarction After First Acute Myocardial Infarction: A Nationwide, Case-Control Study.

Background and Purpose: No previous study has compared the impact of dipyridamole-based triple antiplatelet therapy on secondary stroke prevention and long-term outcomes to that of dual antiplatelet therapy (DAPT) in patients with acute myocardial infarction (AMI) and previous stroke. This study aimed to evaluate the impact of dipyridamole added to DAPT on stroke prevention and long-term outcomes in patients with cerebral infarction after first AMI. Methods: This nationwide, case-control study included 75,789 patients with cerebral infarction after first AMI. A 1:4 propensity score matching ratio was adopted based on multiple variables. Finally, the data of 4,468 patients included in the DAPT group and 1,117 patients included in the Dipyridamole-DAPT group were analyzed. Primary outcome was overall survival. Secondary outcomes were cumulative event rate of recurrent MI or stroke, and cumulative intracerebral hemorrhage (ICH) and gastrointestinal bleeding rate. Results: Long-term survival rate was comparable between the two groups (log-rank P = 0.1117), regardless of sex analyses. However, after first year, DAPT subgroup revealed better survival over DAPT-dipyridamole subgroup (log-rank P = 0.0188). In age subgroup analysis, a lower survival rate was detected in younger patients from the Dipyridamole-DAPT group after first year (log-rank P = 0.0151), but no survival difference for older patients. No benefit of Dipyridamole-DAPT was detected for patients after AMI, regardless of the myocardial infarction type. DAPT was superior to Dipyridamole-DAPT in patients who underwent percutaneous coronary intervention (PCI) (log-rank P = 0.0153) and ST elevation myocardial infarction after first year (log-rank P = 0.0019). Dipyridamole-DAPT did not reduce cumulative event rate of recurrent MI or stroke in patients after AMI. Moreover, Dipyridamole-DAPT increased the cumulative ICH rate (log-rank P = 0.0026), but did not affect the cumulative event rate of gastrointestinal bleeding. In Cox analysis, dipyridamole did not improve long-term survival. Conclusions: This nationwide study showed that Dipyridamole-DAPT, compared with DAPT, did not improve long-term survival in patients with stroke after AMI, and was related to poor outcomes after 1 year. Dipyridamole-DAPT did not reduce recurrent rate of MI or stroke, but increased the ICH rate without impacting the incidence of gastrointestinal bleeding.

Takotsubo cardiomyopathy as an underlying mediator of myocardial infarction with normal coronary arteries.

OBJECTIVE: The purpose of the present study was to describe our experience with myocardial infarction with normal coronary arteries (MINCA) with regards to the prevalence, clinical characteristics, possible underlying etiologies (including Takotsubo cardiomyopathy, TCM) and the short- and long-term outcomes associated with this condition. METHODS: We retrospectively analyzed the records of 596 consecutive patients presenting with acute myocardial infarction over a 4-year period and identified 24 patients (14 female, 10 male) with angiographically normal coronary arteries. Demographic and clinical variables and outcomes were reviewed. RESULTS: Mean patient age was 59 +/- 20 years. The presumed MINCA mechanism was TCM in 10 patients (41.7%), probable myocarditis in 5 (20.8%), coronary spasm in 4 (16.7%), coronary thrombus in 3 (12.5%) and aortic dissection in 2 patients (8.3%). After a mean follow-up of 19 +/- 14 months, 2 patients with probable myocarditis had died of cardiovascular causes, 1 patient with aortic dissection had died due to sepsis after surgery and 1 patient with TCM had died of noncardiovascular causes 2 years after discharge. CONCLUSION: In this study, we found that MINCA occurred in 4% of patients with acute myocardial infarction undergoing emergent coronary angiography, with the most frequent underlying mechanism being TCM.

Long-term clinical follow-up after successful direct coronary stenting without predilatation.

BACKGROUND: Direct stent implantation without predilatation is considered a promising new technique that may reduce procedural time, radiation exposure, ischemic time and cost, but little information is available concerning the long-term outcome. The aim of this study was to investigate the long-term clinical outcome of successful direct stenting without predilatation. METHODS: We prospectively undertook a clinical follow-up program (minimum 8 months) in a consecutive series of 101 patients (113 lesions) who were successfully treated with direct stenting without predilatation. RESULTS: Clinical follow-up was obtained in all 101 patients at a mean period of 12.8 months (range 8 to 18.9). Stress test results were available in 94 patients (94%). During the follow-up period, 23 patients (23%) had one or more events, which included death in 2 patients (2%), target vessel revascularization in 14 (14%), myocardial infarction in 1 (1%) and positive stress test results or recurrence of symptoms (Canadian Cardiovascular Society I to II) treated medically in 6 (6%). Cumulative event-free survival at 8 and 18 months were 80% and 72%, respectively. Long-term clinical event rate was not significantly different among the clinical presentations, lesion types, or stent types. Angiographic follow-up was performed in 43 (43%) patients with 45 lesions. Restenosis (defined as 50% diameter stenosis) was observed in 14 of the lesions (31%). CONCLUSIONS: Direct stenting without predilatation is an effective method of coronary intervention in terms of low long-term clinical event rate.
