The effect of Wenyang Huoxue decoction combined with Baduanjin exercise on the cardiac function and quality of life of patients with Yang deficiency coronary heart disease complicated with chronic heart failure.

Background: Heart failure (HF) caused by coronary heart disease (CHD) is becoming increasingly common, and it still has a high morbidity and mortality rate. Previous studies have found that Wenyang Huoxue decoction combined with Baduanjin exercise can improve the cardiopulmonary function of patients with CHD, but it is not clear whether the heart function of patients with CHD complicated with HF can be improved by this treatment. This study aimed to evaluate the clinical effect of Wenyang Huoxue decoction combined with Baduanjin exercise on CHD complicated with HF.

Assessment of heavy metal pollution in surficial sediments from a tropical river-estuary-shelf system: A case study of Kelantan River, Malaysia.

To understand the source-to-sink of pollutants in the Kelantan River estuary and the adjacent shelf area in Malaysia, a total of 42 surface sediment samples were collected in the Kelantan River-estuary-shelf system to analyze for grain size, total organic carbon (TOC) content, Al and heavy metals (Cr, Ni, Cu, Zn, Cd and Pb). The surficial sediments were mainly composed of clayey silt and the TOC content in sediments decreased from the river to the shelf. The surficial sediments experienced Pb pollution; Cr only showed a certain level of pollution in the coastal area of the estuary but not in other areas, and Ni, Cu, Zn, and Cd showed no pollution.
