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 evaluate effects of three modalities with intravenous immrnoglobulin(IVIG) infusion in the treatment of Kawasaki disease(KD). Methods 76 KD cases were treated by the IVIG in the Deparment of Pediatric of Kaiping Central Hospital from 1998 to 2004.The three modalities were as follows: four days treatment(0.4 g/kg,for four days continuance),two days treatment(1 g/kg,for two days continuance),one day treatment(2 g/kg,for one day).Results(1) In treatment of fever,conjunctiva congest and mouth change,and recover in white blood cell and erythrocyte sedimentation,one day treatment and two days treatment had better curative effects with significantly difference(P0.05).(3)In the prevention of coronary artery dilate(CAD),one day treatment and two days treatment had better curative effects significantly difference(P

OBJECTIVE: Comparative analysis of the clinical curative effect of manipulative reduction and TRV- CRP treatment of BPPV, comfort degree during reset and quality of life improvement. METHOD: One hundred and thirty-two patients with BPPV were randomly divided into two groups ,one group underwent the traditional manip- ulative reduction, the other group with TRV-CRP. DRI and VAS was evaluated in the pre and after treatment and evaluation of the efficacy was conducted. The results of two groups were compared. RESULT: The effective rate of manipulative reduction after a week treatment was 89. 23% and TRV-CRP.was 98. 51%, which was higher in TRV-CRP group than that of the manipulation reduction group(P<0. 05). The comfort degree of the manipulation reduction group was 4. 54±2. 48,higher than the TRV-CRP group which was 5. 48±1. 44 (P<0. 05). The score of DHI showed no significant difference before treatment between manipulation reduction group and TRV-CRP group(P>0. 05), the score of the two groups were decreased after a week of reduction, but the improvement of TRV-CRP group was higher than that of manipulation reduction group(P<0. 05). CONCLUSION The success rate of TRV-CRP was higher than that of manipulative reduction,but manipulative reduction comfort degree was higher than TRV-CRP, the two methods can both improve the quality of life of patients with BPPV. TRV-CRP has many advantages over manipulative reduction, but manipulative reduction is simple with low cost, and the effect is still a great advantage. In clinical work, we should reasonable combine the two methods,so as to improve the cure rate of RPPV.
