Abstract: Objective To explore the dynamic characteristics of stigmatization in HIV/AIDS patients and provide scientific evidence for psychological care. Methods HIV/AIDS patients receiving antiretroviral therapy (ART) treatment in Nanning Fourth People's Hospital were randomly selected for baseline and 1 year follow-up questionnaire survey including internalized HIV stigma, anticipated HIV stigma, exposure to HIV stigma. The differences between the two groups at different time points were dynamically compared to analyze the changing characteristics of stigma in HIV/AIDS patients. Results After one year of ART treatment, among the eight items of internalizing stigma, five items including the proportion of feeling ashamed of being infected with HIV/AIDS, feeling unclean because of being infected with HIV/AIDS, feeling inferior to others because of having HIV/AIDS, feeling guilty because of having HIV/AIDS, and having a poorer self-perception due to how others view HIV/AIDS decreased significantly from 34.0% to 43.5% at the baseline to 19.5% to 29.5%, showing significant improvement with statistical significance (χ2=18.586, 14.277, 10.473, 12.219, 9.934, P<0.05); among the nine items of anticipated stigma, four items including the proportion of community/community workers not taking my needs seriously, discriminating against me, refusing to provide services for me, and healthcare workers avoiding contact with me decreased significantly from 16.0% to 27.5% at the baseline to 7.0% to 15.5%, respectively, showing significant improvement with statistical significance (χ2=13.690, 15.787, 12.034, 12.593, P<0.05); among the 16 items of exposure to HIV stigma, six items including the proportion of experiencing physical attacks, psychological pressure from spouses/partners, being refused sexual relationships, losing jobs or other economic sources, being rejected or losing a job opportunity due to HIV/AIDS, changing job nature due to HIV/AIDS, or being refused medical services decreased significantly from 2.5% to 15.0% at the baseline to 1.0% to 8.0%, respectively, showing significant improvement with statistical significance (χ2=8.619, 15.558, 6.061, 9.049, 5.432, 8.156, P<0.05). Physical assaults on people with HIV/AIDS increased by 5.5 percent(χ2=5.368, P<0.05). Conclusions Through 1-year dynamic monitoring, 48.48% of the three dimensions of stigma of HIV/AIDS patients were alleviated. Treatment intervention, self-acceptance and the creation of a good non-discriminatory social environment have an important impact on the stigma of HIV/AIDS patients and deserve the attention of society as a whole.

Conclusion The anti-drug propaganda and education should be strengthened among the students majoring in sport arts, and the function of anti-drug videos should be greatly exploited to maximize the effect of education.

Objective:To explore the accuracy and clinical effect of computer navigation system in locating the tunnel position in anterior cruciate ligament (ACL) reconstruction.Methods:A retrospective case-control study was conducted to analyze clinical data of 60 patients with ACL rupture treated in Daping Hospital of Army Military Medical University from March 2017 to March 2018, including 44 males and 16 females, aged 15-48 years (mean, 26.3 years). Computer navigation system was used to locate the internal orifice of intra-articular femoral and tibial tunnel in 30 patients (navigation group), and artificial location of intra-articular femoral and tibial tunnel in 30 patients (control group). The operation time and complications of two groups were recorded after operation. The tunnel position was evaluated by CT three-dimensional reconstruction, and the ratio of the tunnel position on the lateral surface of the femoral condyle to the tibial platform was evaluated by the grid method. The proportion sites from the deep posterior edge of lateral intercondylar surface of the femur to the shallow anterior edge (DS) and from the upper edge to the lower edge (HL) were used to represent the position of the femoral tunnel, and the proportion sites of the line connecting the anterior and posterior edge of the tibial plateau were used to represent the tibial tunnel position. The postoperative tunnel position was compared between the two groups. The knee joint stability (Lachman test, pivot shift test) and knee joint function score (Lysholm score, Tegner score) were compared between the two groups before operation and 12 months after operation.Results:All patients were followed up for 12-24 months (mean, 15 months). The operation time was (56.1±8.1)minutes in control group versus (76.0±6.7)minutes in navigation group ( P<0.05). In navigation group, 2 patients had skin edge necrosis at the place where the navigation needle was installed. The proportion of DS in femoral tunnel was (27.2±3.7)% in navigation group versus (33.9±4.4)% in control group ( P<0.05). HL proportion site was (36.6±4.8)% in navigation group versus (38.9±4.9)% in control group ( P<0.05). Proportion of the tibial tunnel at the anterior and posterior edge of the tibial plateau was (44.9±1.8)% in navigation group and (44.7±3.0)% in control group ( P>0.05). Both groups showed significant improvements in Lysholm score, Tegner score, Lachman test and pivot shift test 12 months after operation compared to the preoperative levels ( P<0.05), but the knee joint function score and knee joint stability score had no significant difference between the two groups 12 months after operation ( P>0.05). Conclusions:No significant differences are found between computer navigated and manually navigated ACL reconstruction with regards to knee joint stability, knee joint function, and tibial tunnel localization. However, computer assisted navigation enables the location of the lateral femoral tunnel closer to the anatomical position.

Objective:To investigate the expression of long non-coding RNA (lncRNA) CALCOCO1 in bladder cancer tissue and its effect on the proliferation and migration of bladder cancer cells by regulating miR-200a-3p.Methods:The relative expression levels of CALCOCO1 in bladder cancer tissues and adjacent tissues were analyzed by TCGA database. Human bladder cancer cells UM-UC-3 were selected, and the cells were divided into negative control group and CALCOCO1 group, and NC plasmid and CALCOCO1 plasmid were transfected into UM-UC-3 cells respectively. The expression level of CALCOCO1 in each group was detected by quantitative real-time polymerase chain reaction (qRT-PCR). The proliferation and migration ability of UM-UC-3 cells were detected by MTT assay and Transwell migration assay. Bioinformatics technology was used to predict and dual-luciferase reporter gene experiments to verify the targeting relationship between CALCOCO1 and miR-200a-3p. The expression levels of miR-200a-3p in UM-UC-3 cells in each group were detected by qRT-PCR. Western blotting was used to detect the expression of UM-UC-3 cells proliferation and migration phenotype in each group. Measurement data were expressed as mean ± standard deviation ( ± s), t-test was used for comparison between two groups, and repeated measurement analysis of variance was used for comparison at different time. Results:Compared with adjacent tissues, the relative expression level of CALCOCO1 in bladder cancer tissues was significantly lower, the difference was statistically significant( P<0.01). The relative expression of CALCOCO1 in UM-UC-3 cells in CALCOCO1 group and negative control group was 9.66±2.51 and 1.07±0.59, respectively. The relative expression level of CALCOCO1 in CALCOCO1 group was significantly higher than that in negative control group, the difference was statistically significant ( P<0.01). Compared with the negative control group, the proliferation activity of UM-UC-3 cells in the CALCOCO1 group was decreased ( P<0.05), and the migration number of UM-UC-3 cells was significantly decreased ( P<0.01). CALCOCO1 had a binding site with miR-200a-3p ( P<0.01). The relative expression of miR-200a-3p in UM-UC-3 cells in CALCOCO1 group and negative control group was 1.02 ± 0.31 and 5.79 ± 1.68, respectively, the difference was statistically significant ( P<0.01). Compared with the negative control group, the expression levels of proliferation phenotype proteins CCNB1, CCNE1 and CCND2 in UM-UC-3 cells in CALCOCO1 group decreased, and the expression levels of migration phenotype proteins FOXC2 and Fibronectin decreased. Conclusion:The expression of CALCOCO1 is down-regulated in bladder cancer tissue, promoting the expression of CALCOCO1 can inhibit the proliferation and migration of bladder cancer UM-UC-3 cells through targeted down-regulation of miR-200a-3p expression.

Objective To analyze the spatial and temporal characteristics of hand, foot and mouth disease (HFMD) in Hunan Province from 2016 to 2020. Methods The data of HFMD in Hunan Province from 2016 to 2020 were collected from China's Disease Prevention and Control Information System. HFMD spatial autocorrelation analysis was conducted by ArcGIS 10.2 software at county level, and spatial-temporal scan statistical analysis was performed by SaTScan 9.7 software. Results A total of 714 157 cases was reported in Hunan Province during 2016-2020, with an average annual incidence rate of 208.36/100 000. Global spatial autocorrelation showed that HFMD had a positive spatial correlation on the county scale in Hunan Province during this period. Local spatial autocorrelation indicated that the hot spots were mainly concentrated in the north of central Hunan, the east of central Hunan and the west of Hunan. Spatial-temporal scanning analysis revealed the first class clusters (RR = 6.65, P< 0.001) covering 34 counties in northern and central Hunan, mainly distributed in Yueyang City, Changsha City, Zhuzhou City, Yiyang City and Xiangtan City from May 2018 to June, and the second class clusters (RR = 3.02, P < 0.001) covering 40 counties in western Hunan and central and southwest Hunan from April 2016 to June 2016. Conclusion HFMD incidence exhibits seasonal and regional characteristics in Hunan Province. The prevention and control of HFMD should be guided by combining the characteristics of spatial-temporal clustering.
