ObjectiveTo analyze the trend of stroke mortality among residents in Handan City of Hebei Province from 2017 to 2023, to evaluate the impact of this mortality on life expectancy, and to provide data support for formulating stroke prevention and control strategies. MethodsStroke mortality surveillance data were collected in Handan City from 2017 to 2023. The crude mortality rate, standardized mortality rate, gender-specific mortality rate, and subtype-specific mortality rate of stroke were calculated. The average annual percentage change (AAPC) was used to analyze the trend of stroke mortality. Arriaga’s decomposition method was used to estimate the influence of stroke mortality on life expectancy across all age groups and different stroke subtypes. ResultsThe standardized mortality rate of stroke in Handan City fluctuated from 63.51/100 000 to 103.54/100 000 from 2017 to 2023, showing a significant decreasing trend (AAPC=-7.46%, P<0.001). The changes in stroke mortality positively contributed 0.94 years to life expectancy growth. The positive contribution from the 65 to 69 years old group was the greatest, with a contribution of 0.23 years. The declines in the mortality rates of hemorrhagic stroke, ischemic stroke and unclassified stroke contributed 19.94%, 14.61% and 0.44% to life expectancy, respectively. The positive contribution in the 65 to 69 years old group was the greatest, with a contribution of 4.90% and 3.57% for hemorrhagic stroke and ischemic stroke, respectively. The 85 years old and above group made the greatest positive contribution to life expectancy for unclassified stroke, with a contribution of 0.08%. ConclusionThe standardized mortality rate of stroke in Handan City showed a declining trend from 2017 to 2023, which positively contributed to the increase of life expectancy. However, it is still recommended to strengthen the prevention and control of stroke, especially for men and people aged 60 years old and above. At the same time, attention should also be paid to the impact of different factors influencing hemorrhagic stroke and ischemic stroke on life expectancy.

Objective: To assess the risk factors for symptomatic intracranial hemorrhage ( sICH) after endovascu- lar therapy ( EVT) in patients with acute anterior circulation large vessel occlusion． Methods: A retrospective a- nalysis was used to analyze the clinical data of 273 anterior circulation large vessel occlusion ( ACLVO) patients with EVT，of which 158 were male and 115 were female; ages ranged from 33 to 94 years old［71 ( 59，78) years old］，and sICH occurred in 61 cases．The patients' gender，age，history of smoking and alcohol consumption，his- tory of illness，history of oral anticoagulant / anti-antibiotic administration，oral anticoagulant / antiplatelet medication status，intravenous thrombolytic therapy，admission blood pressure，hospitalization days，occlusion location，proce- dure duration，number of times of thrombus retrieval，cause of stroke ( TOAST classification) ，revascularization status ( mTICI ≥2b) ，and admission ASPECT score，admission APACHEII score，and admission NHISS score were collected．Univariate analysis was used to compare the differences in the above indicators between the non- SICH group and the sICH group． Multivariable Logistic regression analysis was used to evaluate the independent factors for the occurrence of sICH after EVT． Results: The results of univariate analysis showed that mTICI ≥ 2b， admission ASPECT score，and post-EVT sICH were significantly negatively correlated ( P＜0. 05) ，while occlusion location ( ICA) ，admission APACHE-Ⅱ score，admission NHISS score＞20，and admission mRS score were sig- nificantly positively correlated with post-EVT sICH ( P＜0. 05) ．The results of the multivariable Logistic regression analysis indicated that mTICI≥2b ( OR = 0. 314，95% CI: 0. 106－0. 929) and admission ASPECT score ( OR = 0. 775，95% CI: 0. 604－0. 995) are protective factors for sICH after EVT，while occlusion location ( ICA) ( OR = 2. 047，95% CI: 1. 033－4. 054) and admission APACHE-Ⅱ score ( OR = 1. 236，95% CI: 1. 140 －1. 340) were risk factors for sICH after EVT． Conclusion Higher admission APACHEII score，lower admission ASPECT score，occlusion location ( ICA) ，and mTICI ＜2b are independent risk factors for the development of sICH after EVT in patients with acute ACLVO．

Percutaneous coronary intervention(PCI),as one of the primary approaches for revascularization,still faces complications such as restenosis,myocardial ischemia-reperfusion injury and no-reflow/slow-flow phenomena,with no currently effective interventions ensuring long-term efficacy.Based on Li Dongyuan's theory that"fire and original qi cannot coexist",this article inherited Academician Chen Keji's academic perspective on"toxin-stasis pathogenesis"and the hemodynamic characteristics of coronary arteries to propose a"four-stage pathological progression"in post-PCI patients,namely spleen-stomach impairment-original qi deficiency-endogenous yin-fire-toxin-stasis accumulation.It emphasized that the heart vessels rely on qi and blood for nourishment and patency for function,elucidated the therapeutic rationale of Danggui Buxue Decoction,and presented the self-formulated Yixin Hemai Prescription,modified through syndrome differentiation,and performed simultaneous reinforcement and dredging,in order to provide diagnosis and treatment ideas for coronary heart disease after PCI treated with TCM.

Platelets are well-known for their functions in blood clotting and vascular repair. However, in recent years, the regulatory role of platelets in the occurrence and development of malignant tumors has received significant attention. While extensive research has been conducted on the regulation of tumors by circulating platelets in peripheral blood, there is a lack of coherence and continuity among these studies. The tumor microenvironment encompasses the intricate network of cellular and acellular elements that surround and interact with tumor cells, creating a supportive ecosystem for their survival and growth. It plays a crucial role in the initiation and progression of tumors. Similar to dark matter in the universe, platelets, as tiny and enigmatic entities, play an essential role in tumor development and treatment within the tumor microenvironment. Although our current understanding of platelet regulation in the tumor microenvironment is limited, they hold immense untapped potential. In-depth studies on the tumor microenvironment have revealed platelets as a meaningful component, influencing various aspects of tumor development, metastasis, and immune evasion. Platelets, through the release of various bioactive substances or direct interaction with tumor cells, impact tumor progression while being influenced by the tumor in return. Therefore, understanding the role and mechanisms of platelets in the tumor microenvironment is of great importance for tumor prevention and treatment. This review provides a summary of the research progress on the interplay between platelets and tumors in the tumor microenvironment, and presents a promising outlook on the potential of platelets in tumor therapy.

Objective:To examine the spatial and temporal distribution characteristics of first-time callers with suicidal ideation and risk factors related to suicidal ideation in a psychological assistance hotline in Henan Province.Methods:The computerised counselling operating system of the Henan Provincial Psychological Assis-tance Hotline was used to extract data from 31 401 callers who called the hotline between January 2020 and October 2023.A circular distribution and kernel density analysis were employed to investigate the spatial and temporal distri-bution of first-time callers with suicidal ideation.Binary logistic regression analysis was employed to investigate the risk factors for suicidal ideation.Results:A total of 5 494 first-time callers were included in the study,of whom 1 697(30.9％)reported suicidal ideation in the previous two weeks.The temporal distribution of suicidal ideation calls indicated a peak between 12:36 and 01:08.The weekly distribution further revealed that the majority of calls occurred on Fridays.In terms of spatial distribution,the primary hotspots for callers with suicidal ideation were clus-tered around Zhengzhou and Xinxiang.Meanwhile,the secondary hotspots exhibited a dispersed distribution across multiple centers within the province.Logistic regression analysis revealed that being under 20 years old(OR=11.85),being unemployed(OR=1.78),having psychological issues(OR=5.03),experiencing family relation-ship problems(OR=3.67),and facing economic hardships(OR=7.08)were risk factors for suicidal ideation.Conclusion:The time distribution of calls from individuals with suicidal ideation to the psychological as-sistance hotline in Henan Province exhibits a centralized trend,while the spatial distribution of calls demonstrates an imbalance.When receiving initial calls from individuals with suicidal ideation,particular attention should be paid to those aged 20 years old or younger,those who are unemployed,and those experiencing psychiatric,psychological,familial,and economic difficulties.

Objective:To explore the relationship between life events, anxiety, depression, and behavior problems in adolescents.Methods:From September to October 2022, the cluster sampling method was used to select 5 341 adolescents from 4 middle schools in Xinxiang urban area.The subjects and their parents were investigated by the adolescent self-rating life events check list (ASLEC), generalized anxiety disorder scale (GAD-7), patient health questionnaire (PHQ-9), and child behavior checklist (CBCL). SPSS 27.0 software was used for Spearman correlation analysis, and AMOS 28.0 software was used to construct the structural equation model.Results:The scores of anxiety, depression, and behavioral problems were 1 (0, 4), 1 (0, 4), and 3 (0, 10). The total score of life events was 5 (1, 13), and the dimensions scored as follows: interpersonal conflict 1 (0, 4), academic pressure 2 (0, 5), punishment 0 (0, 2), loss 0 (0, 0), health and adaptation problem 0 (0, 1), and others 0 (0, 2). There were positive correlations between life events and its dimensions, depression, anxiety and behavioral problems ( r=0.28-0.69, all P<0.01). In the overall population, anxiety and depression played parallel mediating roles in the impact of life events on behavior problems. Life events could positively predict anxiety ( β=0.68, P<0.01), and anxiety could positively predict behavior problems ( β=0.04, P=0.02). Life events could positively predict depression ( β=0.77, P<0.01), and depression could positively predict behavior problems ( β=0.18, P<0.01). The standardized total effect size of the impact of life events on behavioral problems was 0.622 (95% CI=0.564-0.675). The standardized direct effect size and indirect effect size were 0.460 (95% CI=0.374-0.539) and 0.162 (95% CI=0.108-0.218), accounting for 74.0% and 26.0%of the total effect, respectively. After stratification by gender, the results for male adolescents were consistent with the overall population, while the mediating effect of anxiety was not significant in the female adolescents. Conclusion:Life events can lead to anxiety and depression in adolescents, thereby increasing the risk of behavior problems.

Objective:To explore the role of retinoic acid-related orphan receptor α (RORα) in cognitive impairment induced by chronic alcohol consumption in mice.Methods:(1)The SPF grade RORαflox/flox transgenic mice aged 8 weeks were generated, and 22 transgenic mice were evenly divided into two groups by the method of matching body mass, which were the control group (Con group) and the alcohol group (EtOH group), with 11 mice in each group.(2)Emx1-Cre transgenic mice were used to selectively knock out the RORα gene in the forebrain of RORαflox/flox transgenic mice, producing conditional knockout mice (cKO mice) with the genotype RORαflox/flox-Emx1-Cre+ /+. Fourteen cKO mice were further split into two groups by the method of matching body mass, which were the conditional knockout group (cKO group) and the conditional knockout + alcohol group (cKO + EtOH group), with 7 mice in each group. A chronic alcohol use cognitive impairment model was developed in the EtOH group and cKO + EtOH group through the two-bottle free-choice method, while the Con group and cKO group were given two bottles of water for the same period. Cognitive abilities of mice in all groups were evaluated using behavioral novel object recognition test and Y-maze test.RORα mRNA and protein expression levels in the hippocampus of the Con group and EtOH group were assessed by RT-qPCR and Western blot, respectively.The GraphPad Prism 9.0 software was used for data analysis.One-way ANOVA was used for the comparison of multiple groups and Tukey test was used for further pairwise comparisons.Results:(1) Comparison between Con group and EtOH group: the relative levels of ROR α protein (0.63±0.04) and mRNA (0.78±0.03) in the hippocampus of mice in the EtOH group were significantly lower than those in the Con group((1.00±0.06), (1.00±0.05), both P<0.05). The duration of the EtOH group in the Y maze was significantly lower than that of the Con group ((212.30±32.05) s, (129.30±21.50) s, P<0.05), and the new object recognition index of the EtOH group was lower than that of the Con group ((14.73±25.49)% vs (-15.55±27.88)%, P=0.08). (2)Comparison between Con group and cKO group: the frequency and duration of entering the Y maze of mice in the cKO group ((7.43±2.30) times, (124.10±13.95) s) were lower than those in the Con group ((14.90±3.65) times, (212.30±32.05) s, both P<0.05). There was no statistically significant difference in the new object recognition index between the cKO group and the Con group ( P>0.05). (3) Comparison between the cKO+ EtOH group and the cKO group: the frequency ((2.71±1.11)times) and duration ((161.70±17.95) s) of entering the new heteroarm of Y maze in the KO+ EtOH group were lower than those in the cKO group ((7.43±2.30) times, (124.10±13.95) s, both P<0.05), and there was no statistically significant difference in the new object recognition index ( P>0.05). (4) Comparison between the cKO+ EtOH group and the EtOH group: the frequency of entering new heteroarm of the Y maze in the cKO+ EtOH group ((2.71±1.11)times) was significantly lower than that in the EtOH group (12.18±4.49) ( P<0.05), while there was no statistically significant difference in other behavioral results between the two groups ( P>0.05). Conclusion:Chronic alcohol consumption leads to cognitive impairment through the downregulation of RORα in the hippocampus of mice. Specific knockout of RORα in the forebrain exacerbates cognitive impairment induced by chronic alcohol use. RORα may represent a potential therapeutic target for cognitive impairment resulting from chronic alcohol consumption.

Emotional blunting leads to significant declines in cognitive function and activities of daily living in patients with Parkinson's disease, thereby impacting their quality of life and increasing the caregiver burden. Emotional blunting is a progressive condition, and early detection and intervention can slow its progression, making it necessary to assess emotional blunting in patients early. Currently, there are various tools for assessing emotional blunting, but there is a lack of evidence to guide tool selection. This review discusses the impact of emotional blunting on patients with Parkinson's disease and reviews existing assessment tools for emotional blunting, including their content, applications, advantages, and limitations. It also summarizes issues in the application of these tools and offers future directions, aiming to provide a basis for the identification and assessment of emotional blunting in Parkinson's disease patients.

Objective:To evaluate the effectiveness and safety of minimally invasive anchoring hook intraocular lens (IOL) interscleral suture fixation surgery.Methods:A cohort study was conducted.A total of 74 patients (74 eyes) with aphakia, artificial lens dislocation, or lens dislocation were included at Tengzhou Central People's Hospital from 2021 to 2022.According to the surgical method, the patients were divided into conventional fixation group (39 cases, 39 eyes) undergoing conventional intraocular lens suspension surgery and anchoring hook fixation group (35 cases, 35 eyes) undergoing minimally invasive anchoring hook type IOL interscleral suture fixation surgery.Surgical time, preoperative best corrected visual acuity (BCVA) before surgery and at 1 day and 1 month after surgery, corneal endothelial cell density before and at 1 month after surgery, mislocation of the artificial IOL and the incidence of complications were recorded.This study was reviewed and approved by the Ethics Committee of Tengzhou Central People's Hospital (No.2019-20), and all patients signed the informed consent form.Results:One day and 1 month after surgery, the BCVA of the anchoring hook fixation group was better than that of the conventional fixation group, and the differences were statistically significant (both P<0.05). The preoperative corneal endothelial cell densities of the anchor hook fixation group and conventional fixation group were (2 431±556) and (2 406±625)cells/mm 2, and the postoperative 1-month corneal endothelial cell densities were (2 012±703) and (2 004±759)cells/mm 2, respectively, without statistically significant difference (both P>0.05). The average surgical time of the anchoring hook fixation group was (67.1±7.2) minutes, which was significantly shorter than (93.1±17.9) minutes of the conventional fixation group, and the difference was statistically significant ( t=13.654, P<0.001). During the 1-month follow up, no IOL mislocation occurred in the two groups, and two eyes in the routine fixation group developed anterior chamber hemorrhage, accounting for 5.1%, no anterior chamber bleeding occurred in the anchoring hook fixation group.Corneal edema was observed in 6 eyes and 1 eye of the conventional fixation group and anchor hook fixation group, accounting for 15.4% and 2.9%, respectively.Macular edema was observed in 2 eyes of the conventional fixation group, accounting for 5.1%, and no macular edema occurred in the anchoring hook fixation group.Throughout the entire follow-up, there was no case of low intraocular pressure, ciliary detachment, exposed sutures, or requiring secondary surgical intervention in either group. Conclusions:Both minimally invasive anchoring hook IOL intrascleral suture fixation and conventional IOL suspension are safe and effective.Compared with conventional IOL suspension surgery, anchoring hook IOL intrascleral suture fixation surgery has more advantages in postoperative visual recovery, shorter surgical operation time and a lower incidence of postoperative complications.

Metastasis is a pivotal and intricate process in the progression of malignant tumors,strongly correlating with poor prognosis.Approximately 90%of cancer-related mortality is attributed to metastasis,with the five-year survival rate for patients with metastatic solid tumors ranging from 5%to 30%.Consequently,a comprehensive understanding of the underlying biological mechanisms driving metastasis is essential for unraveling its core processes and developing novel therapeutic strategies.The metastatic cascade involves tumor cells navigating numerous biological barriers,including detachment from the primary tumor,invasion of blood vessels or lymphatics,survival in circulation,extravasation into distant organs and subsequent adaptation to the microenvironment.To surmount these challenges,tumor cells undergo phenotypic changes,genetic mutations and dysregulating signaling pathways.Additionally,microenvironmental factors(such as angiogenesis,matrix remodeling and immune evasion)play a critical role,orchestrating the initiation and growth of metastatic lesions in an interdependent manner.Organ-specific metastasis,a distinct subset of metastasis,involves dynamic bidirectional interactions between tumor cells and the microenvironment of target organs.These interactions determine the selectivity of metastatic spread and drive the adaptive evolution of both the tumor and the organ,which encompasses multiple layers of cellular interactions,including cell-cell and cell-matrix signaling.Tumor cell mutations,the release of specific signaling molecules,the capacity to withstand circulatory pressures,and signaling exchanges with target organs collectively govern the selective nature of organ-specific metastasis.Furthermore,factors intrinsic to the target organ-such as its regenerative potential,metabolic profile,immune surveillance mechanisms and matrix stiffness-further facilitate the adaptive remodeling of metastatic cells within these environments.Thus,the bidirectional selection and adaptation between tumor cells and target organs form a dynamic,complex system that reshapes our understanding of metastatic tumor development.While current research emphasizes shared biological features in metastasis,the successful formation of metastatic tumors depends not only on these common mechanisms but also on the unique characteristics governing organ-specific metastasis.The interplay between generalizable and organ-specific mechanisms profoundly influences the metastatic outcome.This review aimed to consolidate our current knowledge of these shared and distinct processes,analyze the evolving understanding of the bidirectional selection between tumor cells and target organs,and assess the current status of metastatic risk prediction models for patients without metastasis.Furthermore,the paper discussed the challenges and opportunities in managing advanced-stage metastatic tumors,offering new insights and potential clinical strategies to improve prognosis and treatment outcomes.
