Objective:New HIV infections serve as a crucial indicator for assessing the dynamic changes in the HIV epidemic. This study aims to estimate the number of new HIV infections in Dehong Dai and Jingpo Autonomous Prefecture of Yunnan Province (Dehong), using a back-calculation method that integrates diagnosis delay approaches and Bayesian theory. Additionally, it compares the differences between these two estimation methods.Methods:Data were obtained from the Chinese Information System for Disease Control and Prevention. Based on CD4 + T lymphocytes (CD4) counts depletion model, the first CD4 count prior to antiretroviral therapy of HIV-infected individuals diagnosed in Dehong from 2010 to 2023 was utilized to retroactively determine the infection date of HIV-infected individuals and ascertain the annual number of new HIV infections who had been diagnosed. Subsequently, the diagnosis delay distribution method and Bayesian theory were leveraged to assess the diagnosis probability of newly infected individuals, thereby projecting the number of new HIV infections in the region over the specified period. Results:During 2010-2023, a total of 5 693 individuals aged 15 and above, excluding mother-to-child transmission, were diagnosed with HIV in Dehong. After excluding 364 cases due to missing CD4 count results or abnormal first CD4 counts (≥2 000 cells/μl), 5 329 HIV-infected individuals were included in the final analysis. Through CD4 counts back-calculation from 2010 to 2023, the annual number of new infections diagnosed was 479, 427, 337, 305, 256, 219, 194, 193, 131, 166, 120, 71, 42 and 47. When using the diagnosis delay distribution method and life table analysis, the cumulative diagnosis probability rose from 0.301 within one year to 0.913 within 14 years, leading to a reduction in the number of estimated new infections from 577 in 2010 to 168 in 2023, with a total estimate of 4 412 (95% CI:4 350-4 480). Alternatively, based on Bayesian theory, the diagnosis probability increased from 0.413 within one year to 0.946 within 14 years, leading to a reduction in the number of estimated new infections from 557 in 2010 to 122 in 2023, with a total of 3 814 (95% CI: 3 787-3 837). Conclusions:Both methods yielded consistent results in estimating new HIV infections in Dehong from 2010 to 2023. Given the region's ongoing expansion of HIV testing, the estimates derived from Bayesian theory may more accurately reflect the actual situation. These findings provide a reference basis for formulating and optimizing HIV/AIDS prevention and control strategies in Dehong, facilitating progress toward the goal of eliminating AIDS by 2030 in the region.

Objective:To understand the willingness of pre-exposure prophylaxis (PrEP) use to prevent HIV infection and related factors in men who have sex with men (MSM) in Yunnan Province.Methods:Cross-sectional study method and snowball sampling method was used to carry out the survey in 14 cities (autonomous prefectures) in Yunnan from April to June 2021. According to national sentinel surveillance program, the sample size was 400 at national sentinel sites and 100 at provincial sentinel sites. The related factors of PrEP use willingness were analyzed by multiple logistic regressions with software SPSS 22.0.Results:A total of 2 450 questionnaires were completed, the rate of having heard of PrEP was 68.5% (1 677/2 449), the willingness rate of PrEP use was 56.7% (1 343/2 368), the willing rate of PrEP use at their own expense was 30.6% (724/2 368), and the willingness rate of free PrEP use was 56.2% (1 330/2 367). The of multivariate logistic analysis results showed that related factors of low willingness to use PrEP included aged 40-49 years and 50 years or above (a OR=2.49 and a OR=4.48), Han ethnic group (a OR=1.47), residence in other provinces (a OR=1.64), education level of senior high school (a OR=1.96) and college or above (a OR=3.49), sample source of bath house (a OR=3.53), online recruiting (a OR=2.53) and voluntary counseling and testing (a OR=1.42), local living time for 3-6 months and 7-12 months (a OR=0.18 and a OR=0.25) ,class 2 and 3 of survey areas (a OR=3.63 and a OR=1.71), having no anal sex with men in the past week (a OR=2.60), having no commercial homosexual behavior in the past six months (a OR=13.32) and self-perceived higer risk for HIV infection (a OR=0.50). Conclusions:There was more than half of MSM with willingness to use PrEP. The health education to promote PrEP use should be strengthen in MSM who had low willingness to use PrEP from underdeveloped areas, in Han ethnic group, with older age, from other provinces, with shorter local living time and self-perceived low risk for HIV infection.

Objective:To assess and compare the performance of limiting-antigen avidity enzyme immunoassay (LAg-Avidity EIA) and pooling PCR in the surveillance for recent infection rates of HIV-1 in men who have sex with men (MSM).Methods:Blood samples were collected from MSM selected through snowball sampling method in sentinel surveillance in 13 prefectures of Yunnan province from 2016 to 2017. The samples were tested for HIV-1 antibody. The confirmed positive samples were tested by LAg-Avidity EIA. The negative samples were tested by pooling PCR. The recent infection rates of HIV-1 were estimated by the algorithm based on LAg-Avidity EIA and pooling PCR respectively. The two results were compared.Results:During 2016-2017, a total of 5 363 blood samples were collected from MSM, in which 407 samples were HIV-1 positive (including 177 positive tested previously) and 4 956 samples were HIV-1 negative. A total of 211 samples(91.7%) were tested by LAg-Avidity EIA, 69 were confirmed to be recent infections. A total of 4 469 samples were tested by pooling PCR, 8 were confirmed to be acute infections. The recent infection rates of HIV-1 from 2016 to 2017 estimated by LAg-Avidity EIA were 3.36% and 4.84%, and the recent infection rates estimated by pooling PCR were 3.27% and 3.02% respectively. The differences in recent infection rates of HIV-1 estimated by the two algorithms were not significant.Conclusions:The recent infection rates of HIV-1 estimated by LAg-Avidity EIA and pooling PCR in sentinel surveillance in MSM in Yunnan had good consistency from 2016 to 2017. Using the two methods might have a better stability in continuous surveillance for recent infection rates of HIV-1.

Objectives:To investigate the proportion of MSM among males over 15 years old and analyze its related factors to provide a reference for estimation of MSM size.Methods:Using cross-sectional survey design, multi-stage sampling method, and street interception survey method, a survey was conducted on males over 15 years old in Kunming from October to December 2019, with an estimated sample size of 9 908.Results:Totally, 10 707 males were recruited from 30 sites in 5 counties, and 10 283 were effectively surveyed with a response rate of 96.0%. Respondents aged 16 to 40 accounted for 75.3% (7 748), senior high school or above 71.1% (7 312), and unmarried 49.8% (5 121). The proportion of homosexual behavior in the past half-year was 1.06% (95% CI: 0.86%-1.26%), and the age-adjusted rate was 0.97% (95% CI: 0.78%-1.16%). And multivariate logistic regression showed the associated factors for homosexual behavior as following: proportion of main urban area was 2.217 times (95% CI:1.004-4.895) that of the outer suburbs, registered residence outside Kunming was 0.421 times (95% CI:0.260-0.682) that of in Kunming, having been in Kunming ≤6 months was 2.282 times (95% CI:1.262-4.126) that of >6 months, senior middle school or above was 0.336 times (95% CI:0.228-0.495) that of junior middle school and below, and being married was 0.462 times (95% CI:0.303-0.705) that of unmarried. Conclusions:The proportion of over 15-year-old males who have recently practiced male-male behavior was close to 1.00% in Kunming. The relevant factors included survey areas with a permanent residency of Kumming, short-time residency, education level, and marital status. This study obtained the data and related factors, which provided a reference for estimating MSM size in Yunnan province.

Objective To understand the characteristics of newly detected HIV infection cases and related high risk behaviors in the areas with high HIIV infection prevalence in Yunnan province.Methods A questionnaire survey was conducted with census method during January to March 2016 among newly detected HIV infected persons in Dehong,Honghe,Lincang and Dali prefectures in Yunnan during 2012-2015.Results Among 451 HIV seropositive cases,the major transmission route of HIV was heterosexual contact,accounting for 92.5％ (417/451).The total awareness rate of AIDS related knowledge was 73.0％ (329/451).The rates of condom use at sex with regular sexual partners,occasional sexual partners,commercial sexual partners and men who have sex with men within 1 year before knowing their infection status were 48.7％ (167/343),4.2％ (7/165),9.9％ (15/151) and 0.0％ (0/3),respectively.The risk factors for using no condom at sex with regular sexual parmers included living at Dali,being farmer,unmarried,cohabitation,divorced and widowed,monthly income under 1 000 yuan (RMB),living in urban area before infection,knowing no AIDS related knowledge etc.The risk factors for using no condom at sex with occasional sexual partners included living in Dehong,Honghe and Lincang,aged ≤30 years and being farmer.The injecting drug users accounted for 8.2％ (37/450) and 75.5％ of these cases had received AIDS related intervention (340/450).Conclusion High prevalence of heterosexual transmission of HIV,poor AIDS related knowledge on awareness,high risk behavior and poor condom use and poor intervention service utilization were found among newly detected HIV infected persons in areas with high HIV infection prevalence in Yunnan.

OBJECTIVETo understand the high risk behaviors of female sex workers (FSWs) in Yunnan province in 2013.

METHODSA cross-sectional investigation was conducted during April to June, 2013 in Yunnan province, census was used to the investigation where the number of FSWs was close to 200, while probability sampling was used where the number of FSWs was obviously over 200. A total of 25 574 cases were investigated, and data on demography and risk behaviors were obtained by questionnaires one by one.

RESULTSA total of 25 574 cases were investigated, AIDS awareness among FSWs in high-level places, middle-level places and low-level place were 98.8% (92/7 401), 98.6% (150/10 995), and 96.0% (281/6 655). FSWs from low-level place had a lower rate than those from the other two types of places (P < 0.01). The rate of condom use each time when having sex with clients within the recent one month among FESs from high-level places, middle-level places and low-level place were 93.4% (6 307/6 755), 93.8% (10 109/10 782) and 90.4% (6 053/6 697), and the FSWs working in low-level place had a lower rate than those from the other two types of places(P < 0.01). Multi-factor logistic regression analysis showed that the following had a lower rate of condom use: the FSWs working in low-level place (OR = 1.56, 95% CI:1.36-1.79; OR = 1.36, 1.16-1.59), over 30 years old (OR = 0.77, 95%CI:0.69-0.85), Yunnan citizen (OR = 0.88, 95% CI:0.77-1.00), minority (OR = 1.32, 95% CI:1.16-1.50), under senior high school (OR = 0.61, 95%CI:0.49-0.75), married (OR = 0.81, 95% CI:0.71-0.92), living together (OR = 0.70, 95% CI:0.51-0.96), divorced or lost spouses (OR = 0.81, 95% CI:0.65-1.02), worked less than 6 months in local areas (OR = 1.74, 95% CI:1.34-2.27), drug users (OR = 1.65, 95% CI:1.11-2.46), had not accepted HIV interventions (OR = 2.91, 95% CI:2.36-3.58), had no knowledge about AIDS (OR = 4.50, 95% CI:3.48-5.82). The main reasons for not using condoms were the clients' unwilling to use, which accounted for 47.62% (270/567). The total rate of drug use was 1.0% (264/25 567) and the FSWs working in middle-level places had the highest rate of injecting drugs, which accounted for 0.6% (70/11 141). The FSWs working in low-level places had a higher rate than those who worked in high-level places and middle-level places in venereal diseases, which accounted for 1.2% (85/6 934) (P < 0.01). The rate of receiving effective interventions was 96.7% (24 717/25 574), the rate of accepting treatment and clean needles among drug users was 21.6% (57/264).

CONCLUSIONHigh risk behaviors were serious among the FSWs who worked in low-level places, especially among the olders, the minorities, people who had lower educational level, the new-comer and drug users, which indicated that more attention needs to be paid among these populations.

BACKGROUNDIn order to minimize the injury reaction during the surgery and reduce the morbidity rate, hence reducing the mortality rate of esophagectomy, minimally invasive esophagectomy (MIE) was introduced. The aim of this study was to compare the postoperative outcomes in patients with esophageal squamous cell carcinoma undergoing minimally invasive or open esophagectomy (OE).

METHODSThe medical records of 176 consecutive patients, who underwent minimally invasive esophagectomy (MIE) between January 2009 and August 2013 in Cancer Institute & Hospital, Chinese Academy of Medical Sciences, were retrospectively reviewed. In the same period, 142 patients who underwent OE, either Ivor Lewis or McKeown approach, were selected randomly as controls. The clinical variables of paired groups were compared, including age, sex, Charlson score, tumor location, duration of surgery, number of harvested lymph nodes, morbidity rate, the rate of leak, pulmonary morbidity rate, mortality rate, and hospital length of stay (LOS).

RESULTSThe number of harvested lymph nodes was not significantly different between MIE group and OE group (median 20 vs. 16, P = 0.740). However, patients who underwent MIE had longer operation time than the OE group (375 vs. 300 minutes, P < 0.001). Overall morbidity, pulmonary morbidity, the rate of leak, in-hospital death, and hospital LOS were not significantly different between MIE and OE groups. Morbidities including anastomotic leak and pulmonary morbidity, inhospital death, hospital LOS, and hospital expenses were not significantly different between MIE and OE groups as well.

CONCLUSIONSMIE and OE appear equivalent with regard to early oncological outcomes. There is a trend that hospital LOS and hospital expenses are reduced in the MIE group than the OE group.
