Objective:To explore the potential category characteristics of social participation in colorectal cancer patients with stoma and analyze the influencing factors of different potential categories, so as to provide references for formulating and implementing targeted nursing measures.Methods:By using the convenience sampling method, colorectal cancer patients with stoma who were hospitalized or had outpatient follow-up visits at Guilin Hospital of Integrated Traditional Chinese and Western Medicine and the Second Affiliated Hospital of Guilin Medical University from January to December 2024 were selected as the survey subjects. A cross-sectional survey was conducted using the general information questionnaire, the voluntary participation Questionnaire, the Existential Anxiety Scale, the Family Support Scale and the Social Support Rating Scale. Potential profile analysis was used to identify the categories of social participation characteristics of colorectal cancer stoma patients, and multivariate Logistic regression was used to analyze the related influencing factors.Results:A total of 240 valid questionnaires were finally retrieved. Among the 240 colorectal cancer patients with stoma, 126 were male and 114 were female, aged 34-75 (55.63 ± 6.52) years. The social participation score of colorectal cancer patients with stoma was (55.84 ± 8.62) points. The results of potential profile analysis showed that the social participation of colorectal cancer patients with stoma could be divided into three potential categories: low participation-inefficient social life type accounted for 38.3% (92/240), medium participation-efficient indoor participation type accounted for 36.3% (87/240), and high participation-efficient outdoor participation type accounted for 25.4% (61/240). The results of multivariate Logistic regression analysis showed that, taking the high participation-efficient outdoor participation type as the reference, age, educational level, presence absence of stoma-related complications, existence of meaningless anxiety, family support, and social support were the influencing factors of low participation-inefficient social life type and medium participation-efficient indoor participation type ( OR values ranged from 0.163 to 1.879, all P<0.05). Conclusions:There are obvious classification characteristics in the social participation of colorectal cancer patients with stoma. Nursing staff can formulate and implement targeted intervention strategies based on different classification characteristics. Starting from the existence of meaningless anxiety in patients, an effective family and social support system should be established to improve their social participation.

The aryl hydrocarbon receptor (AhR) plays a crucial role in regulating many physiological processes. Activating the AhR-CYP1A1 axis has emerged as a novel therapeutic strategy against various inflammatory diseases. Here, a practical in situ cell-based fluorometric assay was constructed to screen AhR-CYP1A1 axis modulators, via functional sensing of CYP1A1 activities in live cells. Firstly, a cell-permeable, isoform-specific enzyme-activable fluorogenic substrate for CYP1A1 was rationally constructed for in-situ visualizing the dynamic changes of CYP1A1 function in living systems, which was subsequently used for discovering the efficacious modulators of the AhR-CYP1A1 axis. Following screening of a compound library, LAC-7 was identified as an efficacious activator of the AhR-CYP1A1 axis, which dose-dependently up-regulated the expression levels of both CYP1A1 and AhR in multiple cell lines. LAC-7 also suppressed macrophage M1 polarization and reduced the levels of inflammatory factors in LPS-induced bone marrow-derived macrophages. Animal tests showed that LAC-7 could significantly mitigate DSS-induced ulcerative colitis and LPS-induced acute lung injury in mice, and markedly reduced the levels of multiple inflammatory factors. Collectively, an optimized fluorometric cell-based assay was devised for in situ functional imaging of CYP1A1 activities in living systems, which strongly facilitated the discovery of efficacious modulators of the AhR-CYP1A1 axis as novel anti-inflammatory agents.

ObjectiveTo analyze the epidemiological and clinical characteristics of surveillance cases in a sentinel hospital for pertussis in Jiangxi Province in 2019, and to provide corresponding references for the prevention and control of pertussis. MethodsCase investigation of pertussis was conducted among sentinel hospital surveillance cases, collecting their basic information, epidemiological characteristics, clinical characteristics, and other information. ResultsA total of 125 pertussis surveillance cases were investigated in 2019, including 73 clinically diagnosed cases (58.40%) and 52 confirmed cases (41.60%). The age of onset was mainly concentrated in children under 5 years old (108 cases, 86.40%), with the largest number of cases in infants aged less than 1-year-old (48 cases, 38.40%). Most cases had a history of receiving pertussis vaccine before onset (110 cases, 88.00%), and the intervals between the onset date and the date of last dose of pertussis vaccine in the 1‒2 doses group were significantly shorter than that in the 3‒4 doses group (U=-5.990, P<0.001). Probable household transmission of pertussis was found in 3 cases. All cases had cough symptoms, mainly manifested as whooping cough (77 cases, 61.60%), in addition to other main clinical manifestations, such as fever (76 cases, 60.80%), vomiting (30 cases, 24.00%), conjunctival congestion (27 cases, 21.60%), and inspiratory whoop (16 cases, 12.80%). A total of 73 cases (58.40%) experienced complications, including 1 death case. All the cases had multiple medical visit experiences before this visit, with an interval of 2 (0,3) days between the onset date and the first visit date. The misdiagnosis rate at the first medical visit was 88.00% (110/125), and the misdiagnosis rate of the first visit in secondary and primary hospitals was significantly higher than that in tertiary hospitals, exhibiting a statistically significant difference (χ²=21.582, P<0.001). ConclusionThe clinical symptoms of pertussis cases are often atypical, and the first diagnosis is prone to misdiagnosis, so it’s necessary to further strengthen the early diagnosis capabilities for pertussis cases in healthcare institutions, especially in the primary healthcare institutions.

Background Exposure to ozone (O₃) is closely associated with an increased risk of mortality in the population, but this association exhibits regional heterogeneity, and relevant research in northern and central-western China is limited. Hohhot, as a typical city in the northern and western region, has seen a significant upward trend in O₃ concentrations (an increase of 17.9 μg·m⁻³ in 2020 compared to 2016). Studies targeting this region can fill the regional research gap. Objective To evaluate the health effects of ground-level O₃ exposure on resident mortality in Hohhot from 2018 to 2023. Methods Air quality, meteorological, and mortality data in Hohhot from 2018 to 2023 were collected. A time-series analysis based on Quasi-Poisson generalized additive model (GAM) was employed, controlling for meteorological factors, day-of-week effects, and holiday effects, to assess the impact of O₃ on non-accidental mortality, mortality from circulatory system diseases (CSD), and mortality from respiratory system diseases (RSD). Results From 2018 to 2023, the non-accidental, CSD, and RSD mortalities in Hohhot amounted to 89721, 47394, and 11378 cases, respectively. The daily maximum 8-hour average O₃ concentration (O₃-8 h) was 90.00 μg·m⁻³. According to the Class I limit (100 μg·m⁻³) of GB 3095—2012 Ambient Air Quality Standard, the annual average number of days exceeding the standard was 144 d. For single-day lag effects, O₃ had the strongest health impact on non-accidental mortality and CSD mortality on the current day (lag0), with effect sizes of 0.78% (95%CI: 0.33%, 1.24%) and 1.10% (95%CI: 0.50%, 1.71%), respectively. The strongest impact on RSD mortality occurred on the second day (lag2), with an effect size of 1.61% (95%CI: 0.61%, 2.62%). The subgroup analyses showed that for every 10 μg·m⁻³ increase in O₃-8 h concentration, the risk of non-accidental mortality in females increased by 0.70% (95%CI: 0.01%, 1.41%); for CSD mortality, the risk in males and individuals aged ≥65 years increased by 0.73% (95%CI: 0.01%, 1.47%) and 0.76% (95%CI: 0.13%, 1.39%), respectively. During the warm season, statistically significant risks were observed for non-accidental, CSD, and RSD mortalities, with increases of 1.07% (95%CI: 0.54%, 1.60%), 1.31% (95%CI: 0.59%, 2.04%), and 2.27% (95%CI: 1.07%, 3.49%), respectively. In the two-pollutant models incorporating sulfur dioxide (SO₂), nitrogen dioxide (NO₂), carbon monoxide (CO), particulate matter with an aerodynamic diameter of 10 micrometers or less (PM₁₀), and fine particulate matter (PM_2.5), the effect estimates (excess risk) of O₃ remained stable and statistically significant (P<0.05), indicating model robustness. Conclusion Ground-level O₃ exposure in Hohhot increases mortalities due to non-accidental causes, CSD, and RSD, with more pronounced effects during the warm season. Females and individuals aged ≥65 years may be susceptible populations. Therefore, relevant authorities should prioritize the potential health risks of O₃ exposure, particularly to vulnerable groups, and promote targeted prevention and control strategies.
