After the necessity of research on bio-entities was pointed out, the advances and status quo in research on the relation between bio-entities were analyzed with concrete ideas and project put forward for the research on bio-entities using scientometric methods according to thecitationrelation in bio-entities similar to that in litera-ture.This kind of research will promote and perfect the research on scientometric theory and practice, and open a new visual angle for the research on knowledge management .

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.

AIM:To investigate the effect of tanshinone IIA on the apoptosis of human umbilical vein endothe -lial cells (HUVECs) after high glucose treatment.METHODS:The cell viability was determined by MTT assay.The cell apoptotic rate was examined by flow cytometry with Annexin V-FITC/PI double staining .The expression of Bcl-2 and Bax, and the release of mitochondrial cytochrome C ( Cyt C) were analyzed by Western blotting .RESULTS: Tanshinone IIA significantly inhibited high glucose-induced decrease in cell viability and increased the cell apoptosis .Additionally, after tanshinone IIA treatment , Bax expression and the release of mitochondrial Cyt C were significantly inhibited , while Bcl-2 expression was increased .CONCLUSION: Tanshinone IIA prevents high glucose-induced endothelial cell apoptosis via mitochondria-dependent pathway .

Objective To study the relationships between hemoglobin concentration,cytokine and cardiac function in patients with ischemic cardiomyopathy.Methods Hemoglobin concentration,sernm TNF-α,IL-6 in 121 patients with ischemic cardiomyopathy were measured,left ventricular ejection fraction(LVEF)by echocardiography,according to hemoglobin concentration,these patients were distributed to the anemic group and the non-anemic group,contrasting to 27 healthy persons.Results The levels of serum TNF-α,IL-6 in the anemic patients group were higher than those in the non-anemic group subjects,but LVEF Wag lower.With the increase of anemia severity,the levels of serum TNF-α,IL-6 significantly increased;there was a positive correlation between LVEF and the levels of serum TNF-α,IL-6(P＜0.01),and a negative correlation between LVEF and Hb concentration.Conclusion The levels of cytokine promote the pathophysiological procedure between cardiac failure and anemic in ICM.

Alzheimer's disease (AD) is a complex neurodegenerative disorder which seriously causes the dementia in elderly people and afflicts millions of people worldwide. Drug discovery for Alzheimer's disease therapy has been a hot research area and a big challenge, in which development of acetylcholinesterase (AChE) inhibitors design was the most active and some AChE inhibitors are commercially available for AD medication already. However, practical using of commercial AChE inhibitors showed their limited usefulness and related adverse effects. Thus, it is extremely urgent to find novel AChE inhibitors with higher potency and less adverse effects. Based on the accurate crystallographic studies about AChE, strategies for multi-binding site AChE inhibitors have been formed, followed by design of the multi-target directed ligands. In this review, the structures and binding modes of commercial AChE inhibitors were briefly discussed, together with the development of AChE inhibitor design for AD therapy: from multi-binding site inhibitors to multi-target directed ligands.

Objective To study the biological exposure limit in bone metabolism damage caused by coexposure to fluorine and arsenic from coal burning in exposed population.Methods One hundred and ninety-eight cases of fluoride and arsenic co-exposed people from Liuchang village,Qinzhen city,Guizhou province were enrolled in the study.Urinary fluorine (UF),urinary arsenic (UAs),urinary hydroxyproline (UHYP),ross-linked Ntelopeptides of type Ⅰ collagen(UNTX) and bone strength index(STI) were detected.BMDS Version 2.1 software was used to calculate UF,UAs benchmark dose (BMD) and its lower confidence limit (BMDL) on the damage of bone metabolism caused by co-exposure to fluorine and arsenic from coal burning.Results The BMD and BMDL range of UF caused by co-exposure to fluorine and arsenic from coal burning were 0.68-1.35 mg/g Cr,0.57-1.11 mg/g Cr.The BMD and BMDL range of UAs caused by co-exposure to fluorine and arsenic from coal burning were 8.36-18.77 μg/g Cr,7.12-15.40 μg/g Cr.Conclusion The biological exposure limits of UF and UAs for bone metabolism toxicity are proposed as 0.57 mg/g Cr and 7.12 μg/g Cr in co-exposure to fluoride and arsenic from coal burning,respectively.
