RESUMEN
Tuberculosis (TB) and human immunodeficiency virus infection / acquired immune deficiency syndrome (HIV/AIDS) are both serious global public health threats. Early detection of infected persons and/or patients through TB/HIV bi-directional screening is crucial for prevention and control strategy in China and globally. In recent years, with the promotion and application of new TB and HIV detection technologies worldwide, TB/HIV bi-directional screening technologies and strategies have made remarkable changes. This expert consensus introduces the significance and challenges of TB/HIV bi-directional screening, summarizes important progress of research and applications, and makes recommendations on screening measures and procedures to further strengthen TB/HIV bi-directional screening in China.
RESUMEN
The acyl-CoA synthetase long-chain (ACSL) belongs to an enzyme encoded by a polygenic family. ACSL, located in the endoplasmic reticulum and outer mitochondrial membrane, can catalyze fatty acids to form acyl-CoA, participating in many physiological processes, such as fatty acid metabolism and membrane modification. The ACSL family plays different roles in the fatty acid metabolism of different cells, and its dysfunction can lead to conditions such as fatty liver, arteriosclerosis, and diabetes. As a major subtype of the ACSL family in the liver, ACSL family member 1 (ACSL1) is mainly involved in the maintenance of cholesterol stability, fatty acid activation, and bile acid metabolism. It is also associated with the development of certain liver diseases such as hepatocellular carcinoma and steatosis. This paper reviews differences in physiological functions and functional characteristics of ACSL family members. It also discusses the advances in studies on the role of ACSL1 in influencing lipid metabolism, regulating cellular iron death, and the development of related diseases such as liver fibrosis, hepatocellular carcinoma, cachexia, steatosis, thyroid cancer, and breast cancer.
RESUMEN
Objective:To compare the preliminary clinical efficacy of iodized oil embolization and improved microspheres injection embolization in patients with hepatic metastasis from gastrointestinal tumors.Methods:In total 100 patients with hepatic metastasis from gastrointestinal tumors were perspective enrolled from July 2015 to July 2017 in the First Affiliated Hospital of Henan University of Science and Technology. The patients were randomly divided into iodized oil group (45 cases) and microspheres group (55 cases) using random number table. The patients in iodized oil group were firstly received regular perfusion chemotherapy, then underwent the embolization with Iodized oil and epirubicin emulsifier. As for the microspheres group, the patients were received epirubicin and microspheres perfusion and embolization alternately after the same regular perfusion chemotherapy. The post-operation complications were observed. The effective rate of tumor controling at each time point was compared between two groups using χ 2 test. Kaplan-Meier method was used to perform the survival analysis. Log-rank test was used to compare the survival rate between two groups. Results:The operation was successfully performed in all the patients, without severe complications found. The follow up time was 18.7±3.4 months. The tumor control rates of 1, 3, 6, 12 and 24 months after operation in the iodine oil group were 71.1% (32/45), 68.9% (31/45), 51.1% (23/45), 28.9% (13/45), 6.7% (3/45) respectively; while in microspheres group were 90.9% (50/55), 89.1% (49/55), 72.7% (40/55), 49.1% (27/55), 23.6% (13/55), respectively. The tumor control rate in microspheres group was superior to that in iodine oil group ( P<0.05). The median lifetime was 12 months and 17 months for iodine oil group and microspheres group respectively, with significant difference (χ2=8.238, P=0.004) found between two groups. As for the microspheres group, the liver abscess was found in one week after operation in 4 patients, who were cured after drainage and anti-inflammatory treatment. Conclusion:The improved microspheres injection embolization is an effective method for the hepatic metastasis from gastrointestinal tumors and superior to iodized oil embolization in tumor controlling, which may prolong the median survival time.
RESUMEN
Objective@#To know condom use negotiation with clients and regular sex partners and condom use in female sex workers (FSWs), and provide reference for the development of comprehensive HIV/AIDS intervention for FSWs.@*Methods@#The cross sectional survey was conducted in Jianshui county and Mengzi county in Honghe Hani and Yi autonomous prefecture. A total of 476 FSWs aged 16 years and above were recruited from entertainment venues, and the information about their demographic characteristics, condom use negotiation and condom use were collected by using questionnaires. Logistic regression model was used to analyze related factors of condom use after negotiation between FSWs and clients unwilling use condom.@*Results@#A total of 852 FSWs who aged (24.29±8.44) years old participated in the survey. In past month, 499 FSWs had negotiation for condom use with unwilling clients (58.6%, 499/852), after negotiation, 441 FSWs (88.4%, 441/499) had consistent condom use in each sex with the clients. In the past one month, 99 FSWs had negotiation for unwilling use condom with regular sex partners (14.4%, 99/687), after negotiation, 54 FSWs (54.5%, 54/99) had consistent condom use in each sex with regular sex partners. Among the FSWs, 266 (53.3%, 266/499) reported that they could say "It is a mandatory requirement" to persuade clients who were unwilling to use condom. 97(19.4%, 97/499) reported that they could say "There is risk for infection" to persuade clients who were unwilling to use condoms. 115 (23.1%,115/499) reported that they could say "It is a mandatory requirement" and "there is risk for infection" to persuade their unwilling clients to use condoms. 21 (4.2%, 21/499) reported that they used other strategies. 22 (4.4%, 22/499) felt that it was difficult to persuade clients to use condoms. Multivariate logistic regression analysis showed that compared with FSWs who felt difficult in persuading clients to use condoms, FSWs who felt moderate difficulty were more likely to have consistent condom use after negotiation (OR=4.00, 95%CI: 1.55-10.32) and FSWs who felt easy in persuading clients to use condoms were also more likely to have consistent condom use (OR=30.17, 95%CI: 3.22-282.44). Compared with FSWs used other strategies to persuade their clients to use condoms, FSWs who said it was a mandatory requirement were more likely to have consistent condom use after negotiation (OR=4.44, 95%CI: 1.41-14.01) and FSWs who said it was a mandatory requirement and there was risk for infection were also more likely to have consistent condom use (OR=5.52, 95%CI: 1.55-19.73).@*Conclusions@#Negotiation for condom use increased the rate of condom use in FSWs in sex with clients who were unwilling to use condom. The negotiation strategy of "It is a mandatory requirement" would promote condom use in FSWs in sex with clients who were unwilling to use condom. Besides, the negotiation strategy of saying "there is risk for infection" had additional effects.

RESUMEN
Objective: To understand the prevalence of HIV infection and syphilis in clients in Ya'an of Sichuan province. Methods: A survey was conducted in clients recruited through snowball method in Ya'an of Sichuan from April 2014 to December 2015. The information of the clients, including basic demography characteristics, AIDS knowledge awareness, high-risk behaviors and others, were collected through face-to-face interviews. Blood sample (5 ml) was taken from each client to test antibodies against HIV and syphilis. Statistical software SPSS 18.0 was used for data analysis. Results: Among the 708 clients, the constituent ratio of those aged ≥50 years was 51.27% (363/708), those in Han ethnic group was 99.72% (706/708), those with junior high school educational level or below was 90.11% (638/708), those who got married or cohabitated with others was 74.15% (525/708), and those who used condoms at each sex was 27.40% (194/708). Seven HIV positive cases were detected and 4 cases were aged ≥50 years. Seven syphilis cases were detected and all the cases were aged ≥50 year. No HIV-syphilis co-infection case was detected. The prevalence of HIV infection and syphilis were all 0.99% (95%CI: 0.30%-1.70%). Results from the multivariate logistic regression analysis showed that the clients who had their first commercial sex behavior at age <30 years (OR=6.61, 95%CI: 1.09-40.18) would have higher HIV positive rate. Conclusion: The rate of condom use was low in the clients in Ya'an and they didn't pay enough attention to their self-protection in sexual activities. Especially the clients aged ≥50 years were with low educational level and had high risk commercial sexual behaviors for HIV infection and syphilis. Close attention needs to be paid to them.

Objective: To understand the characteristics of new-type drug consumption, sexual behaviors and the prevalence of HIV infection among male new-type drug users in Qingdao, Shandong province. Methods: A cross sectional survey was conducted from 2015 to 2016. Participants were recruited from MSM community-based organizations (CBO) and general community through snowball method, relying on volunteers and male peer educators who were on new-type drugs themselves. Face-to-face interview was carried to collect information on drug use and sexual behaviors. Blood samples were collected to test HIV, syphilis and HCV antibodies. Urine samples were collected to test the evidence of new-type drugs. Qualitative variables and quantitative variables were analyzed using Chi-square test/Fisher's exact test and Student's t-test respectively. Multivariate logistic regression was used to analyze related factors of binary variables. Results: A total of 1 034 newtype drug users were recruited, including 431 (41.7%) MSM population and 603 (58.3%) who were not MSM. Compared with the the group of people who were not MSM, people in the the MSM group were younger, unmarried and with higher level of education. The proportion of methamphetamine users were 49.7% (214/431) and 100.0% (603/603) among the groups of MSM or not MSM, respectively. People in the MSM group, 66.8% (288/431) used 5-Methoxy-N, N-diisopropyltryptamine (5-MeODIPT, "foxy" ) in the last six months. However, none from the not-MSM group ever used 5-MeO-DIPT. In the last six months, proportions of sharing new-type drugs with more than two people in the MSM or not groups were 87.9% (379/431) and 97.7% (588/602), respectively (χ(2)=39.84, P<0.01). Proportions of unprotected sexual behavior among the MSM or not groups were 47.5% (285/600) and 7.4% (32/430) respectively (χ(2)=190.10, P<0.01). The proportions of 'group sex' after using drugs among the two groups were 78.1% (335/429) and 5.5% (33/600) respectively (χ(2)=573.73, P<0.01). The prevalence rates of HIV, syphilis and HCV antibody positive among the MSM or not groups were 2.1% and 0.2%, 3.3% and 6.3%, 0.0% and 0.3%, respectively. Conclusion: The prevalence of sharing new-type drugs with more than two people was high among male new-type drug users in Qingdao city. Male new-type-drug-users who were MSM, presented both high prevalence of group sex and HIV infection, and with less condom use. Intervention measures towards this sub-population should be strengthened.

RESUMEN
Objective To analyze the implementation of intervention programs targeted on AIDS high risk sexual transmission groups since 2008,when the relative prevention and control information systems on HIV/AIDS were developed.Methods Data from both aggregated interventions and sentinel surveillance programs from 2008 to the end of 2014 were used.Descriptive statistics were performed to analyze the trends of implementation on high risk groups including men who have sex with men,female sex workers (FSW) and migrant workers.Results From 2008 to 2012,the monthly average numbers receiving intervention programs and the average monthly coverage rate on intervention for MSM,increased from 49000 to 252000,and from 8.6% to 78.5% respectively.The FSW related indicators increased from 329 000 to 625 000,and from 30.9% to 87.0% respectively.Above indexes on the two populations had dropped slightly in 2013 and 2014.Sentinel surveillance data showed that knowledge and behavior indicators observed from the MSM and FSW populations increased annually.The coverage of intervention programs on migrant workers increased from 4.7% to almost 10.0%,but the surveillance data on migrant men showed that the knowledge and behavior indicators were still lower than the other high-risk groups.Conclusion Intervention related to sexual transmission on HIV/AIDS among high-risk populations were effectively implemented,with some achievements seen.However,as sexual contact currently became the main route of AIDS epidemic,new challenges called for serious attention.

<p><b>OBJECTIVE</b>To investigate the relationship between miR-144 and Toll-like receptor 2 (TLR2).</p><p><b>METHODS</b>RT-qPCR was used to determine the expression of TLR2 and its downstream inflammatory cytokine TNF-α in rat macrophage cell line NR8383 transfected by a mimic miR-144 or miR-144 inhibitor. The fragments of 3'UTR region of rat TLR2 mRNA including wild or mutant miR-144 binding site obtained by PCR using rat liver cDNA were ligated to pmirGLO report gene vector digested with SacI and XbaI to construct the recombinant vectors of pmir-TLR2-3'UTR and pmir-mutant-TLR2-3'UTR. The miR-144 targeting TLR2 was further determined by dual luciferase reporter assay and miR-144 mimics.</p><p><b>RESULTS</b>TLR2 and TNF-α in NR8383 cells were decreased after transfection with 100 nmol/L mimic miR-144 for 24 h and increased after transfection with 100 nmol/L miR-144 inhibitor. PCR and double-enzyme digestion with SacI and XbaI confirmed successful insertion of the target fragments. Dual luciferase reporter assay suggested the binding of miR-144 to the 3'UTR of rat TLR2 mRNA.</p><p><b>CONCLUSION</b>miR-144 negatively regulates the expression of TLR2 and its down-stream cytokine TNF-α by targeting TLR2 in NR8383 cells.</p>
