[Effects of nitrogen fertilizer application rate on nitrogen use efficiency and grain yield and quality of different rice varieties].

To provide scientific basis for reasonable application of nitrogen and create varieties with high N use-efficiency, an experiment was carried out to study the effects of nitrogen fertilizer application rate on grain yield, N use rate and quality of different rice varieties. Four different genotypic rice varieties, Nipponbare, N70, N178 and OM052 were used as tested material and three levels of nitrogen application rate (0, 120, 270 kg·hm) were conducted. Urea as nitrogen source was applied as basal (70%) and panicle (30%) fertilizer.

3,7-Bis(2-hydroxyethyl)icaritin, a potent inhibitor of phosphodiesterase-5, prevents monocrotaline-induced pulmonary arterial hypertension via NO/cGMP activation in rats.

Pulmonary arterial hypertension (PAH) is a chronic progressive disease which leads to elevated pulmonary arterial pressure and right heart failure. 3,7-Bis(2-hydroxyethyl)icaritin (ICT), an icariin derivatives, was reported to have potent inhibitory activity on phosphodiesterase type 5 (PDE5) which plays a crucial role in the pathogenesis of PAH. The present study was designed to investigate the effects of ICT on monocrotaline (MCT)-induced PAH rat model and reveal the underlying mechanism.

Efficacy and safety of Huxin formula in patients after CABG: a multicenter, double-blind, randomized clinical trial.

Background: Coronary artery bypass grafting (CABG) is widely used in the treatment of coronary artery disease. A multicenter, double-blind, randomized, controlled clinical trial was designed to evaluate the efficacy and safety of Huxin Formula post CABG.

Patients And Methods: 270 inpatients with coronary heart disease participated in this study.

A multicentre randomized clinical trial on efficacy and safety of huxin formula in patients undergoing percutaneous coronary intervention.

Percutaneous coronary intervention (PCI) is widely used in clinical treatment of coronary artery disease. However, the effects of PCI on preventing restenosis after revascularization and improving the quality of life were not satisfying. Huxin Formula is formulated by modifying an experienced Chinese medicine formula and has been widely used in clinical practice due to its marked effects on coronary heart disease.

Effect of Huxin Formula on reverse cholesterol transport in ApoE-gene knockout mice.

Objective: To observe the effect of Huxin Formula on expressions of the chief reverse cholesterol transport (RCT) associated genes, caveolin-1 and scavenger receptor-BI (SR-BI) in ApoE-gene knockout [ApoE (-/-)] mice.

Methods: Thirty ApoE (-/-) mice of 4-6 weeks old were randomly divided into three groups (A-C). After being fed with high-fat diet for 16 weeks, they were treated with HXF (1 mL/100 g), pravachol (0.

Impact of C-reactive protein on in-stent restenosis: a meta-analysis.

We sought to evaluate the impact of C-reactive protein (CRP) levels on in-stent restenosis after percutaneous coronary intervention.The plasma level of CRP is considered a risk predictor for cardiovascular diseases. However, the relationship between CRP and in-stent restenosis has been a matter of controversy.

Prolonged hypercholesterolemia-induced tissue factor expression in rabbit vein grafts: a potential mechanism for graft failure.

Objectives: To evaluate tissue factor (TF) expression in vein grafts interposed in the arterial circulation of hypercholesterolemic rabbits. Veins implanted in the arterial circulation of normocholesterolemic rabbits respond by inflammation and infiltration by monocytes with transient TF expression. In a hypercholesterolemic milieu these monocytes may differentiate into macrophages capable of enhanced TF synthesis, which may facilitate hyperplasia and thrombosis.

[Study on the inclusion of volatile oil extracted from Herba Pogostemonis and Exocarpium citri by beta-cyclodextrin].

Objective: To investigate the inclusion technology conditions of volatile oil extracted from Herba Pogostemonis and Exocarpium citri in Huxin Fang granules by beta-cyclodextrin.

Methods: The orthogonal design was used. The percent conversion of the oil in inclusion and the yield of inclusion complex were the indices to determine the factors containing the ratio of the oil to beta-cyclodextrin, the ratio of beta-cyclodextrin to water and the grinding time of the mixture of the oil, beta-cyclodextrin and water.

[Systematic review of randomized controlled trials on preventing and treating restenosis after percutaneous coronary intervention with Chinese medicine].

Objective: To evaluate the randomized controlled trials on preventing and treating restenosis after percutaneous coronary intervention (PCI) with Chinese medicine adopting the principle of evidence-based medicine (EBM).

Methods: Pertinent literatures were retrieved roundly, and scored depending on Jadad Quality Scale. Meta-analysis was applied on the total effect of outcomes reported using RevMan 4.

[Progress of study on applying traditional Chinese medicine and drugs in cardiac surgery].

Application of traditional Chinese medicine and drugs in cardiac surgery have won great progress in recent 10 years, mainly presented in aspects of the treatment of coronary heart disease, myocardium protection, cardiopulmonary bypass and pulmonary hypertension.

[Effect of abdominal needling in treating post-cardiosurgical operational gastrointestinal dysfunction].

Objective: To evaluate the clinic effect of abdominal needling (AN) on post-cardiosurgical operational gastrointestinal dysfunction.

Methods: Sixty patients were equally assigned to two groups, the AN group and the control group. AN applied on the AN group was conducted by needling at Xiawan (Ren 10), Qihai (Ren 6), Qipang, Guanyuan (Ren 4), Qixue, Shuifen (Ren 9), Tianshu (St.

[Cluster analysis on TCM syndromes in 319 coronary artery disease patients for establishment of syndrome diagnostic figure].

Objective: To explore the diagnostic figures for TCM syndrome typing in coronary heart disease (CHD) patients.

Methods: A retrospective investigation was carried out in 319 CHD patients hospitalized from Jan. 2004 to Dec.

[Analysis on TCM syndrome distribution laws in 319 patients with coronary heart disease].

Objective: To study TCM syndrome distribution laws in patients with coronary heart diseases (CHD) by epidemiological investigation.

Methods: A clinical survey was carried out in 319 inpatients with CHD, whose diagnosis was confirmed by coronary arteriography, in the authors' hospital from January 2004 to December 2004. The TCM syndrome distribution laws were analyzed, and the relationship of coronary arteriographic picture with TCM syndrome elements, common symptoms, pulse and tongue figures, as well as the correlation between syndrome typing and blood-lipid levels were analyzed, too.
