Objective To investigate the correlation between baseline plasma soluble triggering receptor expressed on myeloid cell-1(sTREM-1),steroid hormone cortisol and dehydroepiandrosterone(DHEA),immunoendocrine markers,and disease severity in patients with pulmonary tuberculosis(PTB).Methods From March 2020 to May 2022,76 PTB patients and 78 healthy controls were recruited.The plasma sTREM-1 levels were compared between controls and PTB patients.Plasma sTREM-1 and C-reactive protein(CRP),interleukin(IL)-6 and interferon(IFN)-y,erythrocyte sedimentation rate(ESR),steroid hormone cortisol and dehydroepiandrosterone(DHEA)were analyzed to correlate with inflammatory transcripts(IL-6,IFN-γ)in peripheral blood mononuclear cells.Results The sTREM,CRP,ESR,IL-6,IFN-γ,cortisol and cortisol/DHEA were significantly increased(P＜0.05)while DHEA was significantly decreased(P＜0.05)in PTB patients compared with the control group.Futhermore,severe PTB patients had higher sTREM-1 and ESR levels than mild and moderate PTB patients.Spearman correlation analysis showed that sTREM-1 was significantly positively correlated with CRP in all patients(P＜0.05).Only in patients with severe PTB,sTREM-1 was significantly positively correlated with cortisol/DHEA(P＜0.05),and significantly negatively correlated with DHEA(P＜0.05).Conclusions High plasma sTREM-1 levels may be an important factor contributing to the persistence of immunoendocrine imbalance specific to advanced disease in patients with PTB.

Objectives:To investigate the epidemiological characteristics and ethnic differences of cardiovascular-kidney-metabolic syndrome(CKM)among the Hani,Dai,Bai,and Lisu populations in Yunnan Province,and to provide evidence for developing effective prevention and control strategies for CKM.Methods:A cross-sectional survey was conducted among four ethnic minority groups.A total of 3 906 permanent residents aged 18 years and older were enrolled using a multistage cluster random sampling method.CKM stages(0-4)were defined based on the 2023 American Heart Association criteria,stages 3-4 were classified as advanced CKM.Descriptive statistics and chi-square tests were used to compare the prevalence of CKM stages across ethnic groups.Modified Poisson regression was applied to estimate relative risk(RR)and 95%confidence intervals(CI)for factors associated with advanced CKM.Results:The prevalence rates of CKM stage 1 and above among the Hani,Dai,Bai and Lisu ethnic groups were 80.1%,87.3%,84.8%and 67.8%,respectively.The prevalence of CKM was generally higher in males than in females,and the prevalence of CKM increased significantly with age.The Dai ethnic group had the highest prevalence of advanced CKM(24.7%,95%CI:22.1%-27.4%),while the Lisu ethnic group had the lowest prevalence of advanced CKM(13.7%,95%CI:11.5%-15.9%).Modified Poisson regression analysis showed that older age and higher body mass index were common risk factors for advanced CKM across all four ethnic groups.Additionally,except for the Lisu ethnic group,the other three ethnic groups had specific individual risk factors:among the Hani ethnic group,low educational attainment(RR=2.18,95%CI:1.12-4.25)and low income(RR=1.47,95%CI:1.00-2.18)were the primary risk factors of CKM.Among the Dai ethnic group,smoking(RR=1.60,95%CI:1.07-2.37)and a family history of cardiovascular disease(RR=1.61,95%CI:1.14-2.27)are the primary risk factors of CKM.Among the Bai ethnic group,male gender(RR=0.48,95%CI:0.29-0.79)was the primary risk factor of CKM.Conclusions:The prevalence of CKM stage 1 or higher is relatively high among the four minority ethnic groups in Yunnan province.There are significant differences in staging characteristics and primary risk factors across ethnic groups,necessitating the development of stratified,differentiated intervention strategies to achieve precise prevention and control and ethnic health equity in terms of CKM.

ObjectiveTo investigate the prevalence of stroke in Songjiang District from 2017 to 2022, to analyze the epidemiological characteristics of stroke incidence, so as to provide a scientific basis for the formulation of stroke prevention and control policies. MethodsData of new stroke incidence from 2017 to 2022 in Songjiang District were obtained from the Shanghai Stroke and Acute Myocardial Infarction Registration and Reporting Information System. In addition, different classifications such as time of onset, gender, age group and types of stroke, were statistically analyzed. Statistical indicators, such as the number of incidence, crude incidence rate, standardized incidence rate and average age of incidence were calculated simultaneously. Joinpoint software were used to calculate the annual change percentage (APC) and the trend of stroke incidence in Songjiang District. ResultsFrom 2017 to 2022, the newly reported cases of stroke were 12 988 in Songjiang District, the crude incidence rate was 325.76/10⁵, and the standardized incidence rate was 127.58/10⁵. The crude incidence rate and standardized incidence rate in males were 363.45/10⁵ and 157.17/10⁵, respectively, but 288.68/10⁵ and 99.02/10⁵ in females. The mean age of onset was (73.12±11.75) years, of which the mean age of onset was (70.86±11.96) years for men and (75.91±10.85) years for women. The incidence of stroke increased with age, rising rapidly after 60 years and reaching a peak in the age group of ≥ 80 years old. The crude incidence rate and standardized incidence rate of stroke in Songjiang District showed a downward trend from 2017 to 2022, with an APC of -6.20% and -8.01%, respectively (P=0.018, 0.007). The newly reported stroke was dominated by ischemic stroke, accounting for 82.81% of the total cases, with a crude incidence rate of 269.77/10⁵ and a standardized rate of 103.84/10⁵. The incidence of stroke presented seasonal characteristics, with the highest incidence in winter, accounting for 26.11% of the whole year. ConclusionThe incidence rate of stroke in Songjiang District shows a declined trend, but the overall incidence is still at a high level. The situation of prevention and control is still serious, with a heavy disease burden. It is necessary to strengthen health education and disease management for the elderly.

Psoriasis is a common immune-mediated inflammatory skin disease with multiple genetic and environmental risk factors.Abnormal vascular hyperplasia,excessive proliferation of keratinocytes and infiltration of various immune cells are the main pathological features.MAPK signaling pathway is involved in the pathogenesis of psoriasis,and SPRED1 has been proved to be a ma-jor negative regulator of MAPK signaling pathway in many diseases.This article reviews the possible role of SPRED1 in the pathogene-sis of psoriasis,in order to provide new insights into the pathogenesis of psoriasis and new directions for the treatment.

Objective To understand the recognition and coping strategies of ICU nurses on post-ICU syndrome in family members of patients during hospitalisation so as to provide a reference for handling post-ICU syndrome of the family members of patients.Methods A phenomenological approach within qualitative research was adopted.Semi-structured in-depth interviews were conducted with 15 ICU nurses from 3 wards of the Second Affiliated Hospital of South China University.Colaizzi 7-step method was applied to analyse and refine the interview data themes.Results Three main themes and nine sub-themes were identified and they were insufficient cognition of post-ICU syndrome of the family members(limited understanding of post-ICU syndrome in family members,difficulty in recognising or ignoring symptoms,uncertainty about the impact of post-ICU syndrome),active coping with post-ICU syndrome of the family members(coping mainly through listening and explaining,coping mainly through verbal and physical actions,diligent patient care)and various factors hindering nurses'coping with post-ICU syndrome of the family members(compassion fatigue,high ICU work intensity,limited contact time with family members).Conclusion ICU nurses have insufficient understanding of post-ICU syndrome with the family members of patients during hospitalisation.It requires to enhance a comprehensive understanding in ICU nurses about post-ICU syndrome of the family members of patients and to optimise coping strategies to alleviate negative emotions of the family members.Additionally,efforts should be made to overcome factors that hinder nurses'coping with post-ICU syndrome of the family members of patients and to promote a harmonious relationship between medical staff and patients.
