ABSTRACT
OBJECTIVE： To put forward the suggestions for improving drug management in clinical drug trials in China. METHODS： “Good clinical practice” “Clinical trials drug” “Drugs for clinical trials” “GCP” “Investigational drug products” as search terms， searching CNKI database， Wanfang database， PubMed database and OVID electronic journal full-text database during Jul. 2014-Jul. 2018. The differences of drug management guidelines and management systems （including management model， staffing and budget evaluation） in clinical drugs between China and the United States were summarized. The suggestions were put forward to the shortage of drugs management of clinical trials in China. RESULTS & CONCLUSIONS： A total of 154 literatures were retrieved， including 33 valid literatures. The guidelines for drug management in clinical trials in the United States were relatively perfect， such as the Guidelines for Drug Management in Clinical Trials promulgated by the American Society of Hospital Pharmacists， while China had not yet published such national guidelines. The drug management in clinical trials in the United States had two modes which is the management of part-time pharmacists in hospital pharmacy department and the management of several full-time pharmacists and pharmacy technicians. Pharmacists or pharmaceutical technicians participated in the whole process of management， and a lot of research was carried out on the budget evaluation of clinical trials drug management. Domestic clinical trials drug management included three modes which is full-time pharmacist management， full-time pharmacist and part-time nurse management， part-time pharmacist and part-time nurse management. Pharmacists and nurses jointly participated in the management， but the whole process management had not yet been achieved， and there were few studies on budget evaluation of clinical trials drug management. It is suggested that the management of clinical trials drug in China can improve the management efficiency and level of clinical trials drug by refining the management system of clinical trials drug， standardizing the management mode of clinical trials drug and carrying out management budget evaluation.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the feasibility and efficiency of extracting protein from bone tissue using trichloroacetic acid (TCA)-acetone precipitation method.</p><p><b>METHODS</b>Hydrochloric acid (HCL) decalcification method and TCA-acetone precipitation method were separately used for bone protein extraction. The efficiencies of these two methods were compared.</p><p><b>RESULTS</b>TCA-acetone precipitation method had significantly higher extraction efficiency. Compared with HCL decalcification method, it had less pollution from bone marrow hematopoietic tissue. Protein band distribution was similar between these two methods.</p><p><b>CONCLUSION</b>TCA-acetone precipitation method is useful for bone proteomics research.</p>

The vitamin-mineral enriched flour (VMF) was a byproduct obtained from a new processing technique of flour milling, and rich in vitamin B group, minerals and dietary fibers.The addition of 10 or 20% VMF to the stock diet composed mainly of white flour failed to improve PER and growth rate of young rats. When the rats were fed the tested diet for 6 weeks, in which the VMF served as the only diet source ot riboflavin, blood glutathione reductase activity coefficient was 1.13 and 1.09 respectively. This indicated that the amount of riboflavin supplied by VMF could maintain an adequate level in the body of the rats.Adult rats were fed high cholesterol plus 10, 20 and 30% VMF, the contents of serum cholesterol, liver lipids and liver cholesterol were similar to those of the normal diet group, these contents, however, in control group were increased obviously. The results suggested that VMF could protect the rats from the increment of serum cholesterol, liver lipids and cholesterol.
