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 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.

Objective To evaluation the Diagnosis value of single and consociation to drawing materials methods with bronchofibroscopy in pulmonary carcinoma.Methods 481 diagnosed patients with pulmonary carcinoma by bronchofibroscopy during July 2000 to July 2006 were analyzed.Four different drawing materials method including clamping,brushing,needling and rinse checking were used to diagnose.The positive rates of these four methods were compared with single and consociation to drawing materials methods.Results The positive rate of clamping,brushing,needling and rinse checking were 83.9%,70%,59.1%and 35.9%respectively,and the total positive rate was 90.2%after being united.Conclusions Bronchofibroscopy is one of the most important methods in diagnosing pulmonary carcinoma. Using multiple drawing materials methods in bronchofibroscopy can improve the accuracy rate of diagnosis of lung cancer significantly.

Objective To improve the clinical blood level Through explore the feasibility of blood free surgery for congenital heart disease.Methods Collected 160 patients with congenital heart disease during January 2014 to December 2016 in our hospital,patients were divided into bloodless surgery experimental group (n =69) and blood transfusion treatment group (n=91) according to perioperative blood use.The basic data which including age,weight and GCS score,preoperative and postoperative hemoglobin(Hb),operation and postoperative pleural effusion drainage,intraoperative extracorporeal circulation time,mechanical ventilation time and blocking time,ICU stay,postoperative hospital stay,total hospital stay,reintubation and re-surgery of the two groups were compared.To investigate the effect of the implementation of bloodless surgical strategy for patients with congenital heart disease.Results 1) The difference between the two groups in age,body weight and GCS was not statistically significant (P＞0.05);2) The differences of Hb and intraoperative and postoperative pleural effusion drainage between two groups were not statistically significant (P＞0.05);3) The differences with cardiopulmonary bypass time,mechanical ventilation time,blocking time,re-intubation,re-surgery and ICU days of two groups were also not statistically significant (P ＞ 0.05);but bloodless surgery patients' postoperative hospitalization days and total hospitalization time was significantly lower than the control group (P＜0.05).Conclusion The implementation of bloodless surgery in congenital heart disease is safe and feasible.It can shorten the patient's hospitalization time.It is worth popularizing in clinical surgical treatment.

There are many ways to treat pathological scars.Silicon gel sheeting as a noninvasive and convenient method, are widely used in clinic.The article reviews the lituratures on theoretical research of silicon gel sheeting and its efficacy in the past 26 years, and analyzes the effectiveness of silicon gel sheeting for comparison with other methods.

Patent legal system is a part of civil law,while protection system for the varieties of traditional Chinese medicines is involved in the market regulation law.Both of them emphasize on different aspects compiementarily in protecting traditional Chinese medicine (TCM) with advantages and disadvantages.To meet the requirements of the development of TCM in the new era,protection scope of the protection system for varieties of traditional Chinese medicines should be promoted,examination system and elimination mechanisms should be improved through the inheritance and innovation of TCM,which may be conducive to protect rights and interests of TCM enterprises and improve the quality of varieties of traditional Chinese medicines.

Surgery is the major treatment option for malignant tumors and some benign neoplasms of the thyroid, most of which are differentiated thyroid carcinoma. Despite the progresses that have been made in surgical techniques, iatrogenic injuries of the parathy-roid and laryngeal nerves, including superior and recurrent laryngeal nerves, could not be completely avoided in the surgical manage-ment of thyroid tumors. In this review, the causes of intraoperative injuries of parathyroid and laryngeal nerves are systematically ana-lyzed with respect to types and extents of surgical operations, changes in topical anatomy, and secondary thyroid surgeries. The princi-ples and strategies for protecting and restoring injuries of the parathyroid and laryngeal nerves are also elucidated for the effective prevention and adequate treatment of these major complications in the thyroid surgery.

Percutaneous radiofrequency ablation (RFA) has been widely used in the treatment of malignant hepatic tumors and has achieved satisfactory effects.Complications after RFA have been taken seriously and the risk of the development of complications is closely associated with tumor location.It is a great challenge for physicians to perform RFA for hepatic tumors in high-risk locations due to related difficulties and risks.This article reviews the complications after RFA for hepatic tumors in high-risk locations and analyzes related control strategies.
