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.

Objective To analyze the factors affecting on early efficacy of intravenous thrombolysis with atleplase.Methods The clinical data of 100 acute cerebral infarction patients treated by intravenous thrombolysis with atleplase were retrospectively analyzed.The patients were divided into early effective group and ineffective group,whieh assessed by National Institute of Health Stroke Scale (NIHSS) with criteria of whether there were ＞ 3 or not at 24 hours after therapy.Univariate analysis and multivariate logistic regression analysis were used to determine the differences of clinical data between the two groups.Results Univariate analysis revealed that the early improvement was significantly associated with favorable outcome at 3 month (P =0.000).Multivariate logistic analysis revealed that the systolic pressure at baseline was moderately positively associated with early improvement (OR 1.031,95％ CI 1.008-1.056,P =0.009).Conclusion Moderately lower baseline systolic pressure is associated with early improvement after thrombolytic therapy which is associated with favorable outcome at 3 month.

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.

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.

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.

Objective To explore the strategies for nursing the ankylosing spondylitis(AS)patients with fractures of thoracolumbar vertebra combined with kyphotic deformity treated with osteotomy and internal fixation.Method The nursing histories of 8 AS patients with fractures of thoracolumbar vertebra combined with kyphotic deformity treated with osteotomy and internal fixation were retrospectively analyzed to summarize the nursing strategies.Result All the 8 patients lived through the perioperative periods, with kyphotic derformity corrected and no complications like pulmonary or urinary system infections.Conclusion Pertinent care and effective special instructions to the patients may be clinically effective in improvement of heal rates of fractures of thoracolumbar vertebra combined with kyphotic deformity,reduction of complications and facilitation of their rehabilitation.

Observations of the ultrastructural changes in neurons of hypothalamie arcuate, supraoptic and paraventricular nuclei were carried out in the rats following gossypol treatment at a dosage of 30mg/kg/day for 5 weeks. The results showed that after gossypol treatment no marked changes in supraoptic and paraventricular cells could be seen at electron microscopic level, and that there appeared a series of ultrastrucrural changes reflecting increased neurosecretory activity in some of arcuate neurons.They were as follows: Golgi complex and rough endoplasmic reticulum were slightlydilated and filled with homogeneous, low electron density materials in their cisternae; the amounts of neurosecretory granules, lysosomes, nucleolus-like bodies, and microtubules were increased. The nature, significance and cause of these changes are discussed.

Objective:To prepare mesalazine hydroxypropyl-β-cyclodextrin ( MSZ-HP-β-CD) inclusion complexes and observe the properties. Methods:The inclusion complexes were prepared by a stirring method and the content of MSZ was determined by HPLC. The preparation technology was optimized by orthogonal test with the inclusion rate and the yield of inclusion complexes as the indices. The inclusion complexes were identified respectively by ultraviolet ( UV) spectrometry, X-ray diffraction ( XRD) and solubility. The dissolution rate was investigated. Results: Using the stirring method, the optimum preparation process was as follows: the inclusion temperature was 35 ℃, the ratio of MSZ to HP-β-CD was 1∶ 4 ( mg/g) , and the inclusion time was 3 h. The average inclusion rate of the complexes was 96. 28%, and the yield was 97. 87%. The identification results showed that the freeze-dried powder was inclusion complexes. Compared with that of MSZ, the dissolution of MSZ- HP-β-CD inclusion complexes was notably enhanced. Conclusion:The prepared MSZ-HP-β-CD with optimized technology has good reproducibility and stable technology, which can obviously improve the dissolution of MSZ.
