Background and purpose:In breast cancer surgery,margin status assessment significantly impacts patient prognosis,with positive margins indicating higher recurrence and metastasis risks.Ensuring complete tumor resection is thus critical for surgical success.Indocyanine green(ICG)has garnered attention for its potential real-time imaging of breast cancer lesions under near-infrared light.This study employed ICG for intraoperative assessment of breast cancer lesion margin status and further explored the possibility of optimizing the safe margin distance surround the lesion in normal breast tissue.Methods:Clinical data of patients admitted to the Department of Thyroid and Breast Surgery,the Fourth Affiliated Hospital of Anhui Medical University(Affiliated Chaohu Hospital),from December 2021 to September 2022 were collected.A retrospective clinical study was conducted on breast cancer patients who were randomly assigned to either the ICG group or the conventional surgery group.Two to three hours before surgery,patients in the ICG group received a peripheral intravenous injection of 0.5 mg/kg ICG.Intraoperative fluorescence imaging was performed on the specimen before and after resection,as well as on the residual cavity.Near-infrared fluorescence imaging equipment was used to quantitatively measure fluorescence intensity of resected lesions at 4 directions(12,3,6,and 9 o'clock)and detect fluorescence in the residual cavity after lesion removal.Specimens were promptly sent to the pathology department for pathological examination,and safety margins of normal breast tissue in the 4 directions were recorded.The Strengthening the Reporting of Observational Studies in Epidemiology(STROBE)checklist was followed for this study.This study was approved by the Ethics Committee of the Fourth Affiliated Hospital of Anhui Medical University(Affiliated Chaohu Hospital)(No.KYXM-202310-46).Results:This study included 50 breast cancer patients,with 24 in the ICG group and 26 in the traditional surgery group.In the ICG group,fluorescence signals were detected at all lesion sites.Specifically,fluorescence density values at the lesion center,margin,and surrounding normal breast tissue were measured as 251.08±10.73,208.08±19.74,and 156.76±16.47,respectively,showing a gradual decrease from center outward with statistically significant differences(P＜0.05).Additionally,fluorescence ratios between the lesion center and margin,and center and surrounding normal tissue,were 1.22±0.13 and 1.62±0.19,respectively.After resection,abnormal fluorescence was observed in 2 of 24 cases in the residual cavity,with 1 case being invasive carcinoma with ductal carcinoma in situ and the other normal breast tissue.Ultimately,this study demonstrated that ICG achieved a sensitivity of 95.9%and a specificity of 97.9%in margin assessment.After specimen resection,the safety margins of normal glandular tissue surrounding the lesion were measured.The safety widths for the ICG group and the concurrent breast cancer surgery group were(8.36±6.42)mm and(15.08±4.75)mm,respectively.This difference was statistically significant(P＜0.05).Conclusion:ICG is a real-time,efficient,and cost-effective tracer that can be used to determine breast cancer margins,with excellent sensitivity and specificity.For early-stage breast cancer patients who are eligible for breast-conserving surgery,this tracer helps to reduce the amount of healthy breast tissue that is removed around the lesion.

Objective: To investigate the prevalence of hypertension, diabetes and hyperlipidemia among HIV/AIDS patients aged 50 years and above receiving antiretroviral therapy (ART) in Wuxi City, Jiangsu Province, so as to provide insights into the prevention and intervention of chronic diseases for these populations. Methods: The HIV/AIDS patients aged 50 years and above receiving ART were recruited at designated HIV/AIDS medical institutions in Wuxi City using the convenient sampling method from March to June 2024. Demographic information, treatment status and self-reported prevalence of hypertension, diabetes and hyperlipidemia were collected through questionnaire surveys. Factors affecting the prevalence of chronic diseases were analyzed using a multivariable logistic regression model. Results: A total of 830 HIV/AIDS patients receiving ART were surveyed, including 656 males (79.04%) and 375 patients aged 50 to <60 years (45.18%). Among them, 366 patients reported having at least one type of chronic disease, including hypertension, diabetes and hyperlipidemia, with a self-reported prevalence rate of 44.10%. Specifically, 280, 114 and 61 patients reported having hypertension, diabetes and hyperlipidemia, with the self-reported prevalence rates of 33.73%, 13.73% and 7.35%, respectively. Multivariable logistic regression analysis showed that male patients (OR=1.725, 95%CI: 1.187-2.507), those with monthly income less than 3 000 yuan (OR=1.521, 95%CI: 1.122-2.063), those with body mass index of 24 kg/m2 and above (OR=1.577, 95%CI: 1.168-2.130), those who initiated ART at ages of 50 years and above (50 to <60 years, OR=1.535, 95%CI: 1.052-2.238; ≥60 years, OR=3.322, 95%CI: 2.191-5.038), those with ART duration of 10 years and above (OR=2.069, 95%CI: 1.419-3.017), and those who received non-first-line regimens (OR=1.776, 95%CI: 1.304-2.418) had higher risks of developing at least one type of chronic disease, including hypertension, diabetes and hyperlipidemia. Conclusions The self-reported prevalence of at least one type of chronic disease, including hypertension, diabetes and hyperlipidemia among HIV/AIDS patients aged 50 years and above receiving ART in Wuxi City was 44.10%. Gender, monthly income, body mass index and ART status are the main influencing factors for the risk of chronic diseases.

Objective:To understand the uptake of post-exposure prophylaxis (PEP) and related factors among male sex workers (MSW) and provide references for the promotion of PEP.Methods:A cross-sectional study was conducted using convenience sampling to recruit MSW participants with the help of a community-based organization in October 2023, in Wuxi City, Jiangsu Province. The sample size was estimated at 340 people. A self-administered questionnaire was used to collect their social demographic characteristics, sexual behaviors, knowledge, beliefs, and uptake of PEP. A logistic regression model was used to analyze factors associated with the uptake of PEP in MSW. The SPSS 26.0 software was used for statistical analysis.Results:A total of 357 participants were recruited, mainly aged 18-20 (55.7%,199/357), unmarried (94.4%,337/357), and having an education background of junior high school or below (50.1%,179/357). Among 357 participants, 64.4% (230/357) knew about PEP, 51.0% (182/357) believed in the efficacy of PEP, and 13.4% (48/357) had experience of using PEP. Among 68 respondents having high-risk sexual behaviors in the past 3 months, 17.6% (12/68) have had uptake of PEP. Multivariable logistic regression analysis showed that group sex with men in the past 3 months (a OR=7.51, 95% CI: 1.37-41.09), HIV testing in the past 3 months (a OR=2.89, 95% CI: 1.16-7.16), the experience of using pre-exposure prophylaxis (a OR=30.18,95% CI: 12.60-72.24) and believing in the efficacy of PEP (a OR=2.94, 95% CI: 1.04-8.29) were the associated factors with the uptake of PEP in MSW. Conclusions:Although the overall uptake rate of PEP in MSW was high, the proportion of using PEP was still low among participants having high-risk sexual behaviors in the past 3 months. Therefore, it is necessary to strengthen HIV risk awareness education considering their characteristics and promote timely uptake of PEP to interrupt HIV transmission.

Anthropometric indexes play a crucial role in identifying obesity. However, as an internationally commonly used indicator of obesity diagnosis, BMI has limitations in distinguishing lean body mass from fat mass. The weight-adjusted waist index (WWI), a novel anthropometric index, assesses adiposity through standardized waist circumference for weight, which presents an excellent capacity to predict the morbidity and mortality risks of various diseases. However, research on WWI is still in the exploratory stage, and there is a lack of unified standards for using this indicator to determine obesity. In addition, its potential application in children and adolescents also urgently needs to be explored. Therefore, this article comprehensively summarizes and compares the distinctive characteristics between WWI and other obesity-related anthropometric indexes. Bibliometric methods are used to analyze the hotspots and trends of WWI-related research, and we focus on discussing the value of WWI in predicting adverse health outcomes, including cardiovascular disease, diabetes, liver and kidney diseases. We aim to promote the application of WWI in a broader field and fully demonstrate its important public health significance and broad application prospects.

ObjectiveTo explore the clinical efficacy of Gouteng prescription in treating the patients with primary hypertension with anxiety disorder due to yang hyperactivity and heat toxin and the impact of the formula on the balance of inflammatory cytokines. MethodA total of 98 patients diagnosed with primary hypertension and anxiety disorder were randomized into control and observation groups. On the basis of conventional western medicine treatment for hypertension， the control group （47 patients） was treated with Shugan Jieyu capsules for 8 weeks， while the treatment group （51 patients） with Gouteng prescription for 8 weeks. The two groups were compared in terms of the blood pressure level， 24-hour blood pressure variability， Hamilton anxiety scale （HAMA） score， Pittsburgh sleep quality index （PSQI） score， quality of life （SF-36 scale） score， traditional Chinese medicine （TCM） syndrome score and efficacy， incidence of adverse reactions， and the levels of interleukin （IL）-1β， IL-6， IL-10， and IL-4 in the serum of peripheral blood. ResultThe final trial was completed with 95 patients， including 46 in the control group and 49 in the observation group. The treatment in both groups lowered the blood pressure and blood pressure variability （P<0.05， P<0.01）. The observation group outperformed the control group in recovering the systolic blood pressure （SBP）， 24-hour mean systolic blood pressure （24 h SBP）， 24-hour systolic blood pressure variability （24 h SBPV）， and 24-hour diastolic blood pressure variability （24 h DBPV） （P<0.05）. After treatment， the HAMA and PSQI scores in both groups decreased （P<0.05， P<0.01）， and the observation group had lower HAMA and PSQI scores than the control group （P<0.05）. Compared with those before treatment， the SF-36 scores in both groups increased （P<0.05， P<0.01）. After treatment， the observation group had higher scores of physiological function （PF）， bodily pain （BP）， social function （SF）， role-emotional （RE）， and mental health （MH） indicators than the control group （P<0.05）. After treatment， the TCM syndrome scores in both groups decreased （P<0.05， P<0.01）， and the observation group had lower score than the control group （P<0.05）. The total response rate regarding TCM syndrome in the observation group was 85.71% （42/49）， which was higher than that （63.04%， 29/46） in the control group （χ²=6.621， P<0.05）. The treatment in both groups lowered the levels of pro-inflammatory cytokines （IL-1β， IL-6） and elevated the levels of anti-inflammatory cytokines （IL-10， IL-4） （P<0.05， P<0.01）， and the changes were more obvious in the observation group than in the control group （P<0.05）. There were no adverse events during the research process. ConclusionGouteng prescription can recover the blood pressure level， reduce blood pressure variability， suppress anxiety state， improve sleep and quality of life， decrease TCM syndrome score， increase total response rate， lower serum IL-1β and IL-6 levels， and elevate serum IL-10 and IL-4 levels in the patients with primary hypertension complicated with anxiety disorder due to yang hyperactivity and heat toxin. It may exert the effects by regulating the balance of pro-inflammatory and anti-inflammatory cytokines.
