Objective To explore the changes in macrophage infiltration behavior during the dynamic evolution of thrombi following the formation of acute carotid artery thrombosis occlusion(ACTO).Methods 15 healthy male New Zealand rabbits were selected to establish an ACTO model by causing injury to the rabbit carotid artery using surgical sutures treated with ferric chloride.All rabbits were randomly divided into 5 groups according to the end-point time using the random number table method,namely 24-hour group,1 week group,4week group,8 week group,and 12week group postoperatively,with 3 rabbits in each group.At 24 hours post-operation,the ACTO model was examined by DS A.At 24 hours,1 week,4 weeks,8 weeks,and 12 weeks post-operation,samples were taken from the thrombotic arterial segment of the 3 rabbits in each group and embedded in paraffin.The thrombus samples were stained with hematoxylin-eosin(HE)and Martius scarlet blue(MSB)to analyze changes in thrombus morphology and composition(including red blood cells,fibrin and collagen fibers).Orbit Imaging Analysis software was used for semi-quantitative analysis of the thrombus composition components.Using immunohistochemistry to detect the distribution of MO and M2 macrophages in thrombi,aimed to summarize the dynamic evolution of thrombus morphology,composition,and macrophage infiltration behavior at different stages following ACTO occurrence.Results The 24-hour DSA results indicated that all experimental rabbits successfully established the ACTO model.(1)HE staining showed a continuous increase in thrombus size from 24 hours to 1 week.By 4 weeks,signs of thrombus dissolution appeared,and at 8 weeks,neovascularization was observed within the thrombus.By 12 weeks,signs of fibrosis were evident in the thrombus.(2)MSB staining revealed that during the acute phase of thrombus formation(within 24 hours after surgery),red blood cells were the predominant component initially,but after this period,fibrin and collagen fibers became the main components.(3)The detection results of MO macrophages showed that 24 hours after surgery,MO macrophages in the thrombus were not evenly distributed throughout the thrombus,but mainly gathered at the thrombus edge;at 1 week after surgery,the positive area percentage of MO macrophage in the thrombus increased compared with 24 hours after surgery(thrombus edge:[41.7±27.0]%vs.[24.6±16.7]%,thrombus core:[35.7±19.6]%vs.[11.1±10.4]%,all P<0.001),and evenly distributed within the thrombus;at 4 weeks after surgery,MO macrophages in the thrombus decreased compared with 1 week after surgery(thrombosis edge:[10.7±6.1]%vs.[41.7±27.0]%,thrombus core:[12.1±8.5]%vs.[35.7±19.6]%,all P<0.001),the differences were statistically significant.At 4,8,and 12 weeks after surgery,MO macrophages within the thrombus did not change significantly with time(thrombus edge:[10.7±6.1]%,[8.0±7.7]%,and[8.9±5.3]%;thrombus core:[12.1±8.5]%,[9.5±4.2]%,and[15.7±11.0]%),and the differences were not statistically significant(all P>0.05).In addition,at 12 weeks after surgery,MO macrophages at the thrombus edge was less than the thrombus core([8.9+5.3]%vs.[15.7±11.0]%,P<0.01).The detection results of M2 macrophages showed that 24 hours after surgery,M2 macrophages in the thrombus were widely distributed throughout the thrombus;at 1 week after surgery,the positive area percentage of M2 macrophages in the thrombus increased compared with 24 hours after surgery(thrombus edge:[22.1±11.3]%vs.[11.4±8.7]%,P<0.001;thrombus core:[24.5±9.8]%vs.[7.6±6.0]%,P<0.001);at 4 weeks after surgery,M2 macrophage in the thrombus decreased compared with 1 week after surgery(thrombosis edge:[10.6±3.7]%vs.[22.1±11.3]%,P<0.001;thrombus core:[9.2±4.3]%vs.[24.5±9.8]%,P<0.001);at 8 weeks after surgery,M2 macrophages in the thrombus increased compared with 4 weeks after surgery([17.9±8.8]%vs.[9.2±4.3]%,P<0.001),and the differences were statistically significant.However,M2 macrophages in the thrombus did not change significantly from 8 weeks to 12 weeks after surgery(thrombus edge:[9.4±6.3]%vs.[8.5±5.3]%,P>0.05;thrombus core:[17.9±8.8]%vs.[14.4±10.0]%,P>0.05).In addition,at 8 and 12 weeks after surgery,M2 macrophages in the thrombus core was greater than the thrombus edge(8 weeks after surgery:[17.9±8.8]%vs.[9.4±6.3]%,P<0.001;12weeks after surgery:[14.4±10.0]%vs.[8.5±5.3]%,P<0.001).Conclusions This study successfully established an ACTO animal model and demonstrated for the first time the dynamic evolution of macrophages within 12 weeks post-thrombus formation.Macrophages may played a significant role in both thrombus formation and fibrinolysis,as well as in the promotion of thrombus dissolution and the formation of new blood vessels within the thrombus which may potentially promote the spontaneous reperfusion of the occluded vessels.The results of this study need further verification.

A large number of non-specific immune cells, such as macrophages, neutrophils and natural killer cells, as well as specific immune cells, such as B cells and T cells, are presented in the atherosclerotic plaques and arterial blood. In addition, immune-related regulatory molecules such as interferon-γ, interleukin-17, and interleukin-1β highly express in atherosclerotic lesion tissues, which is similar to the tumor immune microenvironment and influence the atherosclerosis progression. In this paper, the research progress of immune cells and related factors involved in the immune microenvironment around cerebral atherosclerotic lesions is reviewed to provide idea and basis for its clinical diagnosis and treatment.

Objective To evaluate the effectiveness of the central government-funded echinococcosis control programme in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, so as to provide insights into echinococcosis control. Methods Administrative villages were sampled using a multi-stage cluster random sampling method from Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, and all residents at ages of 12 years and older in the sampled villages were screened for echinococcosis, and schools were sampled using a cluster sampling method, and all children at ages of 12 years and older in the sampled schools were screened for echinococcosis. Domestic dogs were sampled using a systematic random sampling method, and one domestic dog stool sample was collected from each household. Stray dog stool samples were collected outside the villages, and Echinococcus coproantigens were detected using enzyme-linked immunosorbent assay in domestic and stray dogs. In addition, echinococcosis was screened in sheep and cattle in designated slaughterhouses in Tianzhu Tibetan Autonomous County. The trends in the prevalence of echinococcosis in humans and livestock and the positive rate of Echinococcus coproantigens in dogs were examined with the Cochran-Armitage trend test. In addition, individuals screened for echinococcosis were randomly sampled from 2007 to 2022 for survey on the awareness of echinococcosis control knowledge. Results A total of 290 356 person-times were screened for echinococcosis among residents at ages of 12 years and older in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 1 094 residents detected with cystic echinococcosis, and the detection of echinococcosis appeared a tendency towards a gradual decline over years (χ2 = 358.602, P < 0.001). A total of 32 931 person-times were screened for echinococcosis among children at ages of 12 years and older in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 296 children detected with echinococcosis, and the detection of echinococcosis appeared a tendency towards a gradual decline over years (χ2 = 267.673, P < 0.001). A total of 33 230 domestic dog stool samples were tested for Echinococcus coproantigens in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 1 777 Echinococcus coproantigens-positive samples tested, and the positive rate of Echinococcus coproantigens appeared a tendency towards a decline in domestic dogs over years (χ2 = 2 210.428, P < 0.001), while the positive rate of Echinococcus coproantigens showed a tendency towards a rise in domestic animals from 2016 to 2022 (χ2 = 37.745, P < 0.001). The positive rate of Echinococcus coproantigens remained relatively stable in stray dogs in Tianzhu Tibetan Autonomous County, Gansu Province from 2019 to 2022 (χ2 = 0.315, P = 0.575). A total of 10 973 sheep were screened for echinococcosis in Tianzhu Tibetan Autonomous County from 2007 to 2022, with 334 sheep detected with echinococcosis, and the detection of echinococcosis appeared a tendency towards a decline in sheep over years (χ2 = 53.579, P < 0.001); however, there was no significant change in the detection of echinococcosis during the period from 2015 through 2022 (χ2 = 1.520, P = 0.218). A total of 2 400 cattle were screened for echinococcosis in Tianzhu Tibetan Autonomous County from 2017 to 2022, with 231 cattle detected with echinococcosis, and the detection of echinococcosis showed a tendency towards a decline over years (χ2 = 5.579, P < 0.05). The awareness of echinococcosis control knowledge increased from 44.37% in 2007 to 94.00% in 2022 among residents at ages of 12 years and older and from 52.50% in 2007 to 92.50% in 2022 among children at ages of 12 years and older in Tianzhu Tibetan Autonomous County, respectively. Conclusions There has been a reduction in the detection of echinococcosis in humans and domestic animals and the positive rate of Echinococcus coproantigens in dogs and a rise in the awareness of the echinococcosis control knowledge following the implementation of the central government-funded echinococcosis control programme in Tianzhu Tibetan Autonomous County, Gansu Province; however, integrated echinococcosis control measures are still required for further control of the prevalence of echinococcosis.
