Objective:To evaluate the efficacy of drug abuse prevention and treatment and the needs of drug users.Method:A multi-center survey was carried out with a self-designed questionnaire in 10 compulsory detoxification centers among 2400 drug users.Results:The results of the survey indicate that 76.2% of the subjects had never received any drug abuse prevention education before they using drugs. However, 53.6% of the subjects who received drug abuse prevention education thought that the promotion and education are not helpful or hardly helpful. Drug abusers were basically satisfied with most "software" and "hardware" services of the present compulsory drug abuse center. What should be improved is the effectiveness of treatment. Meanwhile, Drug abusers thought that the most urgent needs were: learning skills to prevent relapse; helping to improve living surrounding and helping to find jobs etc.Conclusion:The coverage of the present drug abuse prevention education is not wide enough and need to be improved in its effectiveness and orientation. In order to make drug abuse treatment more effective and meet drug abusers' needs, multi-department and cross-discipline cooperation, exploration and efforts from the whole society are necessary.

Objective: To understand the effects of different expansion ways on collagen and actin of skin and to provide an experiment foundation for the suitable expansion method clinically. Methods: The rabbits were divided into five groups. The expanders were embedded in experimental group. The sirius-red specific staining method was applied to observe the changes of type I collagen and type III collagen and their proportion. Immunochemistry method was used to detect the expression of actin. Results: 1: In group A, B and C, type I collagen arranged turbulently and was thicker and type III collagen decreased relatively at earlier maintaining period. After 4 week, type I collagen arranged regularly and type III collagen was relatively increased. 2: Comparisons of the area about type I, III collagen: At the same maintaining period, there were no significant difference among the group A,B and C. With the extension of maintaining period, the area of type I, III collagen increased gradually, but there was inclined to stabilize at the fourth week in group A, B and at the third week in group C. Comparison of the proportion of collagen I and collagen III: There were significant difference between group A, B and group D, but no significant difference was observed after the fourth week. There were significant difference between group C and control group, but no significant difference was observed after three week. 3. With the extension of maintaining period, the positive expression rates of actin decreased gradually in group A, B, C. At the same maintaining period, significant difference were observed among group A, B, C. The positive expression rates of actin in group C were lower than that of group A at the same maintaining period. Conclusion: The repeated rapid expansion can not only shorten the clinical period but also promote the quality of skin flap. It is a safe and feasible method in clinic.

Objective :
To evaluate the effect of platelet-rich fibrin (PRF) on alveolar ridge preservation after tooth extraction.
Methods:
Randomized controlled trials (RCTs) published before August 25, 2020 about the use of PRF after tooth extraction were searched through the PubMed, Embase, Cochrane Library, HowNet, Wanfang, CBM databases and clinical trial registration centers in China and the United States. Outcome indicators included in the studies included dry socket occurrence, alveolar bone resorption in the horizontal and vertical directions, and the percentage of new bone. Meta-analysis was conducted with Review Manager Version 5.3 software.
Results:
A total of 706 studies were retrieved. After screening, 8 studies were analyzed quantitatively. Meta-analysis results showed that PRF could reduce the absorption of alveolar bone after tooth extraction, which reduced the horizontal bone mass (WMD=-0.71, 95% CI=-1.11 to -0.32, P < 0.05) and buccal (WMD=-1.38, 95% CI =-1.87 to -0.88, P < 0.05) and lingual sides (WMD=-0.49, 95% CI=-0.92 to -0.06, P < 0.05) and increased the percentage of new bone (SMD=1.24, 95% CI =0.25 to 2.23, P < 0.05). However, there was no significant difference in preventing the occurrence of dry socket (RD < 0.01, 95% CI=-0.05 to 0.04, P=0.95) and reducing bone absorption in the vertical direction of mesial (WMD=-0.11, 95% CI=-1.17 to 0.95, P=0.84) and distal (WMD=-0.66, 95% CI=-1.93 to 0.60, P=0.30) alveolar ridge after tooth extraction.
Conclusion
Using PRF alone after tooth extraction can effectively preserve bone mass in the horizontal direction of the alveolar ridge and the vertical direction of the buccal and lingual sides.
