The rate of bone turnover in postmenopausal women accelerates and the newly formed osteoid is poorly mineralized, resulting in the loss of bone mineral content. Meanwhile, the requirement for calcium increases as more bone matrix needs to be mineralized. On the other hand, the reduction of serum estrogen level impairs the absorption of calcium in intestinal tract and the reabsorption in kidney, resulting in the decreased absorption and increased excretion of calcium. Therefore, sufficient calcium intake is critical for maintaining the bone structure in postmenopausal women. The reference intake of calcium differs greatly among different countries. In 2000, China established the adequate intake of calcium for Chinese women aged 50 years and older as 1000 mg/d. Diets provide the optimal source of calcium to prevent osteoporosis. Although calcium supplements have been demonstrated to be beneficial for the bone mineral density in postmenopausal women, its impact on fracture risk and cardiovascular diseases remains controversial. Available evidences suggest that calcium supplements combined with vitamin D are unlikely to increase the risk of cardiovascular diseases.

Intestinal microflora is a general term for microbial communities that reside in the human intestine. In recent years, the research on diseases related to intestinal microbiota has developed rapidly. It is found that intestinal microbiota is closely related to digestive tract diseases, metabolic diseases, immune diseases, mental diseases, and lung diseases. Intestinal dysbacteriosis, mucosal barrier damaging and local immune dysfunction may be involved in a variety of disease processes. In addition, respiratory diseases such as asthma and pneumonia seriously affect human health. The intestinal microbiota is crucial in regulating immune response of lung to pathological mechanism of diseases including asthma, pneumonia and pulmonary tuberculosis. Therefore, it may be a new direction for the treatment of lung diseases by understanding intestinal microbiota in lung diseases, and identifying, describing and manipulating immunity network of pulmonary disease.

Objective To study the effect of milrinone(Mil) and prostaglandin E1(PGE1) on postoperative right ventricular failure(RVF). Methods 28 patients with congenital heart diseases and pulmonary hypertension undergoing cardiopulmonary bypass (CPB) were randomly divided into four groups: control group (group I), receiving Mil (Group II), receiving PGE1 (Group III), and receiving both Mil and PGE1(group IV). The hemodynamic indexes of all the patients, including mean pulmonary artery pressure (PAP), mean arterial blood pressure (MAP), cardiac index(CI), systemic vascular resistance (SVR) and pulmonary vascular resistance(PVR), were measured and compared. Intubation time and side effects were observed. Results Compared with the other three groups, postoperative PAP、PVR and SVR in group IV deceased and CI increased significantly. The intubation time was also shorter in group IV. Conclusion Postoperative RVF can be treated efficiently by using Mil and PGE1.

0.05).Conclusion The rat model of liver-Qi stagnation can be induced by chronic stress,which is different from the syndromes of deficiency of both heart and spleen and the interior disturbance of phlegm-heat.

Polycystic kidney disease is a common human congenital hereditary disease, which can be divided into autosomal dominant polycystic kidney disease and autosomal recessive polycystic kidney disease by genetic methods. In addition to the kidney changes, polycystic kidney disease may also involve multiple body organs and seriously endanger human health. In recent years, studies on etiology and pathogenesis ( especially molecular biology), diagnosis and treatment of polycystic kidney disease have progressed by leaps and bounds. This paper briefly summaries the research status and development of the most common autosomal dominant polycystic kidney disease.

MELAS syndrome(mitochondrial myopathy encephalophathy with lactic acidosis and stroke-like episodes),as one of the most common diseases in mitochondrial encephalomyopathies,is characterized by highly variable manifestations.So,more and more people come to realize the importance of molecular basis of MELAS.This review took the commonest mtDNA point mutation(A3243G) for example to overview its molecular biological mechanism,test strategy and recent progress of study on MELAS syndrome.
