As artificial intelligence technology rapidly advances, its deployment within the medical sector presents substantial ethical challenges. Consequently, it becomes crucial to create a standardized, transparent, and secure framework for processing medical data. This includes setting the ethical boundaries for medical artificial intelligence and safeguarding both patient rights and data integrity. This consensus governs every facet of medical data handling through artificial intelligence, encompassing data gathering, processing, storage, transmission, utilization, and sharing. Its purpose is to ensure the management of medical data adheres to ethical standards and legal requirements, while safeguarding patient privacy and data security. Concurrently, the principles of compliance with the law, patient privacy respect, patient interest protection, and safety and reliability are underscored. Key issues such as informed consent, data usage, intellectual property protection, conflict of interest, and benefit sharing are examined in depth. The enactment of this expert consensus is intended to foster the profound integration and sustainable advancement of artificial intelligence within the medical domain, while simultaneously ensuring that artificial intelligence adheres strictly to the relevant ethical norms and legal frameworks during the processing of medical data.

Objective: To estimate the incidence of HIV-1 infection in men who have sex with men (MSM) in key areas of China through HIV-1 limiting antigen avidity enzyme immunoassay (LAg-Avidity EIA), analyze the deviation from the actual results and identify influencing factors, and provided reference for improving the accuracy of estimation results. Methods: Based on the principle of the cohort randomized study design, 20 cities were selected in China based on population size and the number of HIV-positive MSM. The sample size was estimated to be 700 according to the HIV-1 infection rate in MSM. MSM mobile phone app. was used to establish a detection appointment and questionnaire system, and the baseline cross-sectional survey was conducted from April to November 2019. LAg-Avidity EIA was used to identify the recent infected samples. The incidence of HIV-1 infection was calculated and then adjusted based on the estimation formula designed by WHO. The influencing factors were identified by analyzing the sample collection and detection processes. Results: Among the 10 650 blood samples from the participants, 799 were HIV-positive in initial screening, in which 198 samples (24.78%) missed during confirmation test. Only 621 samples were received by the laboratory. After excluding misreported samples, 520 samples were qualified for testing. A total of 155 samples were eventually determined as recent infection through LAg-Avidity EIA; Based on the estimation formula , the incidence of HIV-1 infection in MSM in 20 cities was 4.06% (95%CI:3.27%-4.85%), it increased to 5.53% (95%CI: 4.45%-6.60%)after the adjusting for sample missing rate. When the sample missing rate and misreporting rate were both adjusted, the incidence of HIV-1 infection in the MSM increased to 5.66% (95%CI:4.67%-6.65%). The actual incidence of HIV-1 infection in MSM in the 20 cities might be between 4.06% and 5.66%. Conclusions: Sample missing and misreporting might cause the deviation of the estimation of HIV-1 infection incidence. It is important to ensure the sample source and the quality of sample collection and detection to reduce the deviation in the estimation of HIV-1 infection incidence.

Objective: To investigate the distribution of HIV-1 genetic subtypes and pretreatment drug resistance (PDR) among men who have sex with men (MSM) from 19 cities of 6 provinces in China. Methods: From April to November 2019, 574 plasma samples of ART-naive HIV-1 infected MSM were collected from 19 cities in Hebei, Shandong, Jiangsu, Zhejiang, Fujian, and Guangdong provinces, total ribonucleic acid (RNA) was extracted and amplified the HIV-1 pol gene region by nested polymerase chain reaction (PCR) after reverse transcription. Then sequences were used to construct a phylogenetic tree to determine genetic subtypes and submitted to the Stanford drug resistance database for drug resistance analysis. Results: A total of 479 samples were successfully amplified by PCR. The HIV-1 genetic subtypes included CRF01_AE, CRF07_BC, B, CRF55_01B, CRF59_01B, CRF65_cpx, CRF103_01B, CRF67_01B, CRF68_01B and unrecognized subtype, which accounted for 43.4%, 36.3%, 6.3%, 5.9%, 0.8%, 0.8%, 0.4%, 0.4%, 0.2% and 5.5%, respectively. The distribution of genetic subtypes among provinces is statistically different (χ²=44.141, P<0.001). The overall PDR rate was 4.6% (22/479), the drug resistance rate of non-nucleoside reverse transcriptase inhibitors, nucleoside reverse transcriptase inhibitors, and protease inhibitors were 3.5% (17/479), 0.8% (4/479) and 0.2% (1/479), respectively. The PDR rate of recent infections was significantly higher than that of long-term infections (χ²=4.634, P=0.031). Conclusions: The HIV-1 genetic subtypes among MSM infected with HIV-1 from 19 cities of 6 provinces in China are diverse, and the distribution of subtypes is different among provinces. The overall PDR rate is low, while the PDR rate of recent infections was significantly higher than that of long-term infections, suggesting the surveillance of PDR in recent infections should be strengthened.

Objective: To learn HIV related stigma and its associated factors among the patients on antiretroviral therapy ( ART ) in Wenshan Prefecture, Yunnan Province, so as to provide evidence for eliminating HIV discrimination. Methods: A total of 419 subjects were recruited by convenience sampling from three ART clinics in Wenshan City and Maguan County between October 2017 and January 2018. HIV/AIDS Related Stigma and Discrimination Scale developed by Li Xianhong et al was employed. The multivariate linear regression model were used to explore the influencing factors for HIV stigma. Results: The median scores of disclosure concern, public rejection, family stigma, internalized stigma, health service providers＇ stigma were 24.00, 6.00, 10.00, 20.00, 2.00, respectively, and the overall was 68.00. The multivariate linear regression analysis showed that female patients ( standardized β=0.135 ) , patients with opportunistic infection ( standardized β=0.120 ), patients had no HIV infected family member ( standardized β=-0.128 ) , patients without family support ( standardized β=-0.175 ) , patients received gift from ART clinics ( standardized β=0.124 ) , patients scored lower in ART knowledge ( standardized β=-0.117 ) were likely to scored higher in HIV stigma. Conclusions The stigma on disclosure concern and internalized stigma dimensions are grievous among ART patients in Wenshan Prefecture. Gender, opportunistic infection, HIV infection in family, family support, receiving incentive gifts from clinics and awareness of ART are associated with HIV stigma.

BACKGROUND: Despite almost two decades of well-funded and comprehensive response efforts by the Chinese Government, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) remains a major problem in China. Yet, few studies have recently examined long-term trends in HIV/AIDS prevalence, incidence, and mortality at the national level. This study aimed to determine the prevalence, incidence, and mortality trends for HIV/AIDS over the past 28 years in China. METHODS: We conducted a descriptive, epidemiological, secondary analysis of the Global Burden of Diseases, Injuries, and Risk Factors Study 2017 data. To evaluate trends in prevalence, incidence, and mortality over the study period from 1990 to 2017, we calculated values for annual percentage change (APC) and corresponding 95% confidence intervals (CIs) using joinpoint regression analysis. RESULTS: A significant increase in HIV/AIDS prevalence was observed for 1990 to 2009 (APC: 10.7; 95% CI: 10.4, 11.0; P < 0.001), and then remained stable for 2009 to 2017 (APC: 0.7; 95% CI: -0.3, 1.7; P = 0.1). A significant increase in HIV incidence was also observed for 1990 to 2005 (APC: 13.0; 95% CI: 12.6, 13.4; P < 0.001), and then a significant decrease was detected for 2005 to 2017 (APC: -6.5; 95% CI: -7.0, -6.1; P < 0.001). A significant increase in AIDS-related mortality rate was detected for 1990 to 2004 (APC: 10.3; 95% CI: 9.3, 11.3; P < 0.001), followed by a period of stability for 2004 to 2013 (APC: 1.3; 95% CI: -0.7, 3.3; P = 0.2), and then another significant increase for 2013 to 2017 (APC: 15.3; 95% CI: 8.7, 22.2; P < 0.001). CONCLUSIONS Although prevalence has stabilized and incidence has declined, AIDS-related mortality has risen sharply in recent years. These findings suggest more must be done to bring people into treatment earlier, retain them in treatment more effectively, actively seek to reenter them in treatment if they dropout, and improve the quality of treatment and care regimens.

This paper reviews the current epidemics of human immunodeficiency virus (HIV) infection in China, particularly the globally available prevention strategies developed and implemented. This review focuses on HIV prevention measures in general, such as education, testing, and counseling and in specific responses to transmission modes, such as blood safety, harm reduction for people who inject drugs, and condom promotion to reduce sexual transmission. We also assess newly developed prevention measures, such as prevention treatment, pre-exposure prophylaxis, post-exposure prophylaxis, male circumcision, and promising potential future preventions, including microbicides and vaccines. Based on this assessment, we provide recommendations for their implementation in China. We conclude that there is no magic bullet for HIV prevention, particularly sexual transmission of the disease, but only a combination of these prevention strategies can control the HIV epidemic.

Background: Youths are disproportionally affected by the human immunodeficiency virus (HIV) infection. We aimed to assess antiretroviral therapy (ART) initiation and viral suppression rates among student and non-student youths in Hangzhou, China. Methods: Data were taken from the Chinese HIV/acquired immune deficiency syndrome Comprehensive Response Information Management System. Youths aged 15 to 24 years who were newly diagnosed with HIV between 2012 and 2016 and were living in Hangzhou were included in the study. Comparisons between student and non-student youths were made for ART initiation within 30 days, 90 days, and 12 months of HIV diagnosis, and the viral suppression rate at 12 months of HIV diagnosis and at 12 months of ART initiation. Results: A total of 707 cases met inclusion criteria, 29.6% of which were students and 70.4% were non-student youths. The student group had a higher proportion of ART initiation compared with the non-student group within 30 days of diagnosis (45.5% vs. 37.0%, P = 0.044), and a slightly higher but not statistically significant proportion at 90 days (67.0% vs. 62.7%), and 12 months (83.7% vs. 78.5%) of HIV diagnosis. ART initiation within 30 days improved from <15% in 2012 to over 65% in 2016 in both groups, and ART initiation within 90 days improved from <30% in 2012 to >90% in 2016. A smaller proportion of students experienced viral suppression compared with the non-student group (9.6% vs. 17.1%, P = 0.011) at 12 months after HIV diagnosis, but the suppression rate was similar at 12 months of ART initiation (69.9% vs. 71.1%, P = 0.743). Conclusions ART initiation in both student and non-student youths has significantly improved between 2012 and 2016. However, the viral suppression rate remained unacceptably low at 12 months of HIV diagnosis in both student and non-student groups. Specific intervention strategies must be taken to address this challenge.

The article reviews major achievements in three broad areas in fighting against HIV/AIDS epidemic in China in past 35 years. Major supportive laws and regulations and policies have been developed and implemented to facilitate national HIV/AIDS programs. The specialized personnel for HIV/AIDS programs have grown up and have played significant roles in the battle against the epidemic. Remarkable achievements have been made in surveillance to monitor the HIV epidemics, in providing care and treatment for people living with HIV, and in providing effective prevention services to key populations at high risk of HIV infection. Challenges are presented and recommendations are provided.

Background: Unprotected anal intercourse (UAI) has previously been associated with human immunodeficiency virus (HIV) infection. Male students who have sex with men (SMSM) are at increased exposure to experience UAI. The aim of this study was to investigate the status of UAI and related factors among SMSM in three northern regions of China. Methods: From November 2018 to January 2019, SMSM, 18 years or older, studying or living in Beijing, Tianjin, or Shijiazhuang, who had anal sex in the past 6 months were recruited by community-based organizations to participate in an unmatched, casecontrol study. Detailed demographic and behavioral information were collected via self-administrated electronic questionnaires and factors related to UAI were assessed using uni- and multivariate logistic regression analyses. Results: Among the 511 SMSM included in the study, 210 (41.1%) reported UAI in the past 6 months. SMSM who had sexual partners at least 10 years older than themselves (odds ratio [OR] = 2.277, 95% confidence interval [CI]: 1.380–3.756), used vacant capsules before sexual activity (OR = 3.858, 95% CI: 1.472–10.106), had a self-perceived moderate-HIV risk (OR = 2.128, 95% CI: 1.403–3.227), and unprotected, first anal intercourse (OR = 2.236, 95% CI: 1.506–3.320) had increased odds of UAI. Conclusions Factors associated with increased odds of engaging in UAI in the past 6 months among SMSM included having older sexual partners, using vacant capsules, having a self-perceived moderate risk of HIV, and unprotected, first anal intercourse. Continuing education on risk reduction, including improving condom decision making in age-discordant relationships could help address the sexual risk behaviors among SMSM.
