Objective:To explore changes in high-risk sexual behaviors and associated factors in HIV-infected men who have sex with men (MSM) in industrial workers, and provide evidence for designing behavioral interventions for this population.Methods:In this observational study, HIV-infected MSM were recruited in industrial workers using convenient sampling during August to September 2021. The sample size was estimated to be 530. A questionnaire was used and combined with routine follow-up to collect socio-demographic characteristics, high-risk sexual behaviors, partner notification, viral load testing and history of sexually transmitted diseases before and after diagnosis of HIV infection. The χ2 test was used to analyze the changes in high-risk sexual behaviors before and after diagnosis and logistic regression was conducted to identify factors associated with high-risk sexual behaviors. Results:A total of 560 HIV-infected MSM in industrial workers were recruited in this study. Of whom, 32.1% (180/560) had unprotected anal intercourse (UAI) within 12 months after diagnosis . The proportions of those having UAI with casual, commercial and regular same-sex partners significantly decreased from 73.4% (381/519), 75.1% (187/249) and 69.5% (207/298) within 12 months before diagnosis to 36.2% (146/403), 40.2% (86/214) and 34.2% (67/196) within 12 months after diagnosis , respectively. Educational level of college or above (a OR=0.41, 95% CI:0.23-0.71), passive anal sex (a OR=0.40, 95% CI:0.19-0.85), both active and passive anal sex after diagnosis (a OR=0.40, 95% CI:0.20-0.83) and no unprotected oral sex (a OR=0.02, 95% CI:0.01-0.05) were negatively associated with UAI within 12 months after diagnosis. Whereas, not considering necessary to use condom consistently after having repeated undetectable viral load (a OR=3.02, 95% CI:1.37-6.69) was positively associated with UAI within 12 months after diagnosis. Conclusions:Compared with that before diagnosis of HIV infection, although the prevalence of UAI seemed to decrease in HIV-infected MSM in industrial workers after diagnosis, nearly one third of them had high-risk sexual behaviors. Therefore, relevant interventions should be strengthened to reduce high-risk sexual behaviors.

Objective:To explore the cognition of the "undetectable equals untransmittable" ("U=U") concept and associated factors among HIV-infected men who have sex with men (MSM) receiving antiviral treatment (ART) in Shenzhen, and provide evidence for designing promotion and advocacy strategies for the "U=U" concept.Methods:We recruited HIV-infected MSM receiving ART using convenient sampling method combined with routine follow-up in Shenzhen through conducting observational survey. The sample size was estimated to be 475. A questionnaire was administered to collect socio-demographic characteristics, sexual behaviors, ART, viral load testing and the cognition towards "U=U" in HIV-infected MSM. Logistic regression was used to access factors associated with acceptance of "U=U".Results:A total of 490 HIV-infected MSM receiving ART were recruited. Of whom, 60.2% (295/490) were aware of "U=U" and 50.6% (248/490) accepted "U=U". Multiple logistic regression showed that participants who had an educational level of college or above (a OR=1.76,95% CI: 1.12-2.75) were more likely to accept "U=U". Those who had no local residency (a OR=0.51,95% CI: 0.29-0.92), had viral load >0 copies/ml in the last testing (a OR=0.61,95% CI: 0.38-0.98) and were unaware of "U=U" (a OR=0.13, 95% CI: 0.09-0.21), were less likely to accept "U=U". Conclusions:HIV-infected MSM receiving ART had a low cognition level of "U=U" in Shenzhen. Promotion and advocacy on this concept through healthcare workers should be enhanced in combination with routine follow-up in order to improve their ART adherence and outcome of treatment. Furthermore, developing related guidelines on "U=U" according to the characteristics of HIV-infected individuals is warranted to improve the normalization of promotion and advocacy on "U=U".

The aim of this study was to evaluate the roles of interleukin (IL)-17A in risk stratification and prognosis of patients with sepsis-associated acute kidney injury (SAKI). Methods: We enrolled 146 sepsis patients (84 non-SAKI and 62 SAKI patients) admitted to the emergency department from November 2020 to November 2021. Patients with SAKI were differentiated based on the severity of acute kidney injury. All clinical parameters were evaluated upon admission before administering antibiotic treatment. Inflammatory cytokines were assessed using flow cytometry and the Pylon 3D automated immunoassay system (ET Healthcare). In addition, a receiver operating characteristic (ROC) curve was utilized to determine the prognostic values of IL-17A in SAKI. Results: The levels of creatinine, IL-2, IL-4, IL-6, IL-17A, tumor necrosis factor alpha, C-reactive protein, and procalcitonin (PCT) were significantly higher in the SAKI group than in the non-SAKI group (p < 0.05). The level of IL-17A revealed significant differences among stages 1, 2, and 3 in SAKI patients (p < 0.05). The mean levels of PCT, IL-4, and IL-17A were significantly higher in the non-survival group than in the survival group in SAKI patients (p < 0.05). In addition, the area under the ROC curve of IL-17A was 0.811. Moreover, the IL-17A cutoff for differentiating survivors from non-survivors was 4.7 pg/mL, of which the sensitivity and specificity were 77.4% and 71.0%, respectively. Conclusion: Elevated levels of IL-17A could predict that SAKI patients are significantly prone to worsening kidney injury with higher mortality. The usefulness of IL-17A in treating SAKI requires further research.

Complex structural variants(CSVs)are genomic alterations that have more than two breakpoints and are considered as the simultaneous occurrence of simple structural variants.How-ever,detecting the compounded mutational signals of CSVs is challenging through a commonly used model-match strategy.As a result,there has been limited progress for CSV discovery com-pared with simple structural variants.Here,we systematically analyzed the multi-breakpoint con-nection feature of CSVs,and proposed Mako,utilizing a bottom-up guided model-free strategy,to detect CSVs from paired-end short-read sequencing.Specifically,we implemented a graph-based pattern growth approach,where the graph depicts potential breakpoint connections,and pattern growth enables CSV detection without pre-defined models.Comprehensive evaluations on both simulated and real datasets revealed that Mako outperformed other algorithms.Notably,validation rates of CSVs on real data based on experimental and computational validations as well as manual inspections are around 70%,where the medians of experimental and computational breakpoint shift are 13 bp and 26 bp,respectively.Moreover,the Mako CSV subgraph effectively characterized the breakpoint connections of a CSV event and uncovered a total of 15 CSV types,including two novel types of adjacent segment swap and tandem dispersed duplication.Further analysis of these CSVs also revealed the impact of sequence homology on the formation of CSVs.Mako is publicly available at https://github.com/xjtu-omics/Mako.

OBJECTIVES:
Inflammation especially the overexpression of inflammasome and inflammatory cytokines, is one of the important reasons that affect the occurrence and development of acute cerebral infarction, including the initiation of cerebral infarction, the progress and recovery of post-infarction injury. This study aims to explore expressions of absent in melanoma 2 (AIM2), interleukin-1β (IL-1β), and interleukin-18 (IL-18) in plasma of patients with acute cerebral infarction and its significance.
METHODS:
A total of 85 patients with acute cerebral infarction were enrolled in the cerebral infarction group. They were assigned into mild, moderate, and severe groups according to the severity of neurological deficits. They were assigned into small, middle, and large cerebral infarction groups according to the area of cerebral infarction. They were assigned into a good prognosis group and a poor prognosis group according to the Modified Rankin Scale (mRS) score on the 90th day after the onset. A total of 85 healthy controls were selected as a control group. The levels of AIM2, IL-1β, and IL-18 in plasma of the cerebral group and the control group were detected by enzyme-linked immunosorbent assay (ELISA).
RESULTS:
The levels of plasma AIM2, IL-1β, and IL-18 in the cerebral infarction group were significantly higher than those in the control group (all
CONCLUSIONS
Expressions of AIM2, IL-1β, and IL-18 are up-regulated in the plasma of patients with acute cerebral infarction, and they are closely related to the severity of neurological deficit, cerebral infarction area, and prognosis in patients with acute cerebral infarction, suggesting that AIM2, IL-1β, and IL-18 may play an important role in the occurrence and development of acute cerebral infarction.
