Objective: To systematically evaluate the effects of AIDS related health education on Chinese university students,and to provide reference for effective prevention and control of AIDS in universities. Methods: Chinese and English databases including China National Knowledge Infrastructure,Wanfang Database,VIP Database,China Biology Medicine disc and PubMed were searched to find literature on the effects of AIDS health education on Chinese university students,which was published from June 30th of 2010 to June 30th of 2019. Rate difference（RD）was adopted as the effect index for the meta-analysis. Results: A total of 173 articles were found out,28 articles of which were included. There were 48 037 study samples,with 23 020 students in the intervention group and 25 017 students in the control group. The results of the meta-analysis showed that compared with the control group,the awareness rates of knowledge about condom（RD=0.21,95%CI：0.11-0.32）and mosquito transmission（RD=0.34,95%CI：0.25-0.43）,the rates of positive attitude to having class with HIV/AIDS（RD=0.21,95%CI：0.12-0.31）and being AIDS prevention volunteers（RD=0.14,95%CI：0.06-0.23）,and the rate of avoiding unprotected sexual behaviors（RD=0.30,95%CI：0.22-0.38）in the intervention group were significantly improved. The results of subgroup analysis showed that the awareness rate of knowledge about mosquito transmission in the comprehensive intervention based on peer education group was significantly improved（RD=0.43,95%CI：0.32-0.53）;the rate of positive attitude to having class with HIV/AIDS in medical students was significantly improved（RD=0.40,95%CI：0.35-0.46）. No publication bias was found by Begger's test and Egger's test. Conclusion Through AIDS health education,the awareness of AIDS-related knowledge among Chinese university students has been obviously improved,while the intervention of attitude and behaviors still needs to be strengthened with the promotion of comprehensive intervention based on peer education.

Objective:To study the significance of H19 gene in the progress from normal mucosa through oral submucous fibrosis (OSF) to carcinogenesis.Methods:Real-time fluorescent quantitative PCR technique was used to detect LncRNA H19 expression level in 12 cases of normal buccal mucosa tissue,33 cases of OSF buccal mucosa tissue and 31 cases of buccal carcinoma with OSF.Results:The relative expression levels of LncRNA H19 in normal buccal mucosa tissues,OSF buccal mucosa tissue and buccal carcinoma with OSF tissue were 1.17 ±0.37,3.44 ± 1.08 and 8.88 ± 1.78 respectively(between each 2 groups,P ＜ 0.01).Conclusion:H19 may involve the occurrence and canceration of OSF.

OBJECTIVE: To analyze the characteristics soft tissue profile in Hunan Han adults with normal occlusion and to explore the differences of the soft tissue profile in gender, region and race. METHODS: Lateral cephalometric radiographs were performed for 323 volunteers (164 females and 159 males) from Hunan Province. The digital cephalometric radiographs were imported into the WinCeph8.0 measurement and analysis system in a same computer. According to the Holdaway analysis method, the mean and standard deviation were calculated. Then the results were compared to the data from Liaoning, Nepalese, Japanese, North American Caucasians. RESULTS: The normal value of cephalometric facial soft tissue profile in Han population adults with normal occlusion in Hunan Province were obtained. There were significant differences in subnasale to H line (Sn-H), upper lip tension, lower lip sulcus depth (Si-PgsLs), and soft tissue chin thickness (Pg-Pgs) between males and females (all P<0.05). Compared with Liaoning Province, significant regional differences in soft tissue facial angle (FH-NsPgs), upper lip sulcus depth (Ss-Ls), Sn-H, lower lip thickness, upper lip thickness, H angle, lower lip to H line (Li-PgsLs), Si-PgsLs, and Pg-Pgs were found in Hunan Province (all P<0.05). Compared with the Japan, significant regional differences in FH-NsPgs, nose prominence (Sn-Pn), lower lip thickness, upper lip tensity, H angle, Li-PgsLs, Si-PgsLs, and Pg-Pgs were found in Hunan Province (all P<0.05). Compared with the Nepalese, significant regional differences in Sn-Pn, Ss-Ls, Sn-H, skeletal profile convexity (A-NPs), basic upper lip thickness, upper lip tensity, H angle, Li-PgsLs and Pg-Pgs were found in Hunan Province (all P<0.05). Compared with the North America, significant regional differences in Sn-Pn, Ss-Ls, Sn-H, A-NPs, basic upper lip thickness, upper lip tensity, H angle, Li-PgsLs, Si-PgsLs and Pg-Pgs were found in Hunan Province (all P<0.05). CONCLUSION There are both similarities and differences in facial soft tissue profile between males and females with normal occlusion in Hunan Province. The characteristics of facial soft tissue profile in Hunan Province are different from that in Liaoning area, Nepal, Japan and North America.
