OBJECTIVE:To provide suggestions for the setting-up of the current pharmacovigilance(PV)system.METHODS:The characteristics of the setup of the PV system in both US and France were analyzed and the problems encountered in current monitoring system of adverse drug effects were pointed out.RESULTS & CONCLUSION:Both American and French PV systems have their own advantages and we should learn from it and draw useful experiences from them.In constructing PV system,China should make improvement in organization,communication,financial resource and information technology etc.

In order to have a better understanding of the relation between vertical dimension and occlusal force,a meter was made by means of straingauge.Five Japanese men were investi- gated for occlusal force at different vertical dimensions.The measurements showed that the maximal occlusal force of the posterior teeth occured at 8 to 15mm or the vertical dimension, the maximal occlusal forec of the anterior teeth occured at 13 to 18mm.This indicated that the occlusal force was closely related to the state of jaw closing muscle.

Leptin,the product of the obese gene,is a 16kDa secreted protein produced by white adipocytes.Because of its dual nature as a hormone and cytokine,leptin plays a role in regulating energy metabolism,inflam-marion,immune response,neuroendocrine and angiogenesis,and so on.The review focuses on the research and controversy of leptin's effect in osteoarthritis.

The concrete methods and experiences for foreign students in case study in the past decades were introduced in this article. We emphasized on teaching students in accordance with their aptitude and step by step, explaining the profound things in a simple way and giving attention to different students' capabilities during teaching. In the practice, we surely felt that case study will bring more advantage than traditional teaching methods, motivate students and improve the capabilities to understand the course content.

Inflammatory reaction plays an important role in the occurrence and development of ischemic stroke. Monocyte chemotactic protein-1 (MCP-1) is one of the subfamily members of the CC chemokine class. It can attract and activate a variety of cells, such as monocytes and T lymphocytes, promote the expression of cytokines, and participate in the occurrence of ischemic brain injury. This article reviews the progresses on the MCP-1 and ischemic stroke-related research.

Objective　To study the effects of deliberated hypotension combined with acute simple hemodilution on blood loss,postoperative hemoglubin of the patients undergoing spinal side(back) protrude correction(SSP).Methods　Twenty four ASA grade Ⅰ to Ⅱ patients undergoing elective SSP were randomly divided into two groups:control group(n＝12) and hypotensive group(n＝12).The all patients received with general anesthesia.In the hypotensive group:acute simple hemodilution was accomplished with infusion of lactated Ringer's solution and Gelofusine of as three times as blood loss.Deliberated hypotensin was induced and maintained with 0.01% sodium nitroprusside 2～6μg/kg/min iv.Intraoperative blood loss,blood transfused volume during operation and postoperative hemoglobin were recorded and compared between both groups.Results　 Blood loss was about 51% lower in the deliberated hypotensive group than that in the control group at the end operation.The average volume of transfused blood during operation was(1200±140)ml in control group,blood transfusion was(400±128)ml in the hypotensive groups.Conclusion Deliberated hypotension combined with acute simple hemodilution can significantly decrease the intraoperative blood loss and the SSP operation can be better tolerated for the indicated patients.

Objective To test the reliability and validity of the collective self-esteem scale for freshman.Methods 800 freshmen finished the Collective Self-Esteem Scale,the Life Satisfaction Scale,and Self-esteem Scale.Results The confirmatory factor analysis shows that collective esteem includes membership esteem,private collective esteem,public collective esteem,and importance to identiy intemal consistency a of the scale and the 4 components of the scale ale between0.6357and 0.8369.All components of the scale except importance to identity have significantly positive correlation with life satisfaction and self-esteem.(0.14＜r＜0.41,P＜0.01).Gids have more scores than boys in total collective esteem(t=3.38,P＜0.01),Private CSE and Importance to Identity (t=3.32,P＜0.01).Conclusion The revised collective self-esteem scale for freshmen has sound reliability and validity.It is a good instrument for measuring collective self-esteem of Chinese freshman.

Gastric cancer is a malignant tumor with the second highest incidence and mortality in the world, and China is one of the countries with the highest incidence of gastric cancer in the world. Research on the regulation of cell cycle protein can provide effective evidence for the mechanism of tumor and gene therapy.G1/S phase is the key point for cell cycle regulation,Cyclin D1 and CDK4 gene and P16 play important roles in this phase and have great correlation with gastric cancer,but the exact relationship between these genes and gastric cancer is still unclear. In order to better understand the expression of Cyclin D1 and CDK4 gene and P16 in gastric cancer, the related researches in recent years were summarized in this paper.

The immunoregulatory effects of mescenchymal stem cell (MSC) and its application have become a focused research topic in recent years. This article reviews the up-to-date research advances in the features and mechanisms of immune regulation of MSC and its application.
