Objective To understand the quality of life of patients with acute mild to moderate ischemic stroke one year after stroke, analyze the factors affecting their quality of life, and provide a scientific basis for improving their health-related quality of life. Methods This study included patients who were diagnosed with acute mild to moderate ischemic stroke between March 2019 and March 2021 in four hospitals in Nanchang. Sociodemographic information and relevant clinical data were collected during hospitalization. The EQ-5D-5L questionnaire was administered to assess health-related quality of life one year after discharge. The Mann-Whitney U test (for two groups) and Kruskal-Wallis one-way ANOVA (for multiple groups) were used to analyze differences in utility scores among various factors. A Tobit regression model was built to investigate the factors influencing quality of life one-year post-stroke. Results A total of 1 181 patients participated in the study, including 791 males (66.98%) and 390 females (33.02%), with an average age of 63.7±10.9 years. Health-related quality of life data collected one year after the stroke revealed that 22.69% of patients experienced pain/discomfort, 17.27% suffered anxiety/depression, 15.66% had mobility issues, 10.33% had difficulties with daily activities, and 8.64% had trouble with self-care. Tobit regression results showed that age (β=−0.263, 95%CI −0.327 to −0.198), gender (β=−0.134, 95%CI −0.189 to −0.080), previous hypertension (β=−0.068, 95%CI −0.120 to −0.016), previous dyslipidemia (β=−0.068, 95%CI −0.126 to −0.011), admission NIHSS score (β=−0.158, 95%CI −0.198 to −0.118), and discharge mRS score (β=−0.193, 95%CI −0.250 to −0.136) were negatively associated with health utility values. Current employment status (β=0.141, 95%CI 0.102 to 0.181) and admission GCS score (β=0.209, 95%CI 0.142 to 0.276) were positively correlated with health utility values. Conclusion One year after an acute mild to moderate ischemic stroke, patients commonly face pain/discomfort and anxiety/depression. Factors affecting overall quality of life include age, sex, current employment status, previous hypertension, previous dyslipidemia, admission NIHSS score, admission GCS score, and discharge mRS score. Clinically, developing scientifically sound and reasonable rehabilitation plans post-discharge is crucial for improving long-term quality of life.
ObjectiveTo systematically evaluate the association between MTHFR gene C677T polymorphism and susceptibility to young and middle-aged adult ischemic stroke among Chinese population. MethodsSuch databases as PubMed, EMbase, The Cochrane Library (Issue 11, 2013), CBM, CNKI, VIP and WanFang Data were systemically searched to collect case-control studies published from Jan 1990 to Dec 2013. RevMan 5.2 was used to quantitatively analyzed the qualified and included studies, the pooled odds ratio (ORs) with 95% confidence interval (CI) were calculated; Stata 12.0 software were used for sensitivity and publication bias analysis. ResultsA total of 10 studies were included, which involved 787 cases and 766 controls. The results of meta-analysis showed that, in overall young and middle-aged adult group (aged less than 60), individuals that carried T allele risked more with ischemic stroke than those carried C allele (OR=1.42, 95%CI 1.07 to 1.89, P=0.02); more susceptibility to ischemic stroke was found among people of TT genotype compared with those of CC genotype (OR=2.11, 95%CI 1.58 to 2.81, P=0.00), as well as those of TT+TC genotype compared with CC genotype (OR=1.97, 95%CI 1.55 to 2.51, P=0.00), and those of TT genotype compared with TC+CC genotype (OR=1.42, 95%CI 1.13 to 1.77, P=0.00). Increased risk was also observed in TT+TC genotype compared with CC genotype in young adult subgroup (aged less than 45) (OR=1.66, 95%CI 1.19 to 2.32, P=0.00). ConclusionMTHFR gene C677T polymorphism is significantly associated with susceptibility to young and middle-aged adult ischemic stroke among Chinese population, and more risk may exist in middle-aged adult population.
Objective To assess the effect of different thrombolytic agents, and different regimens in acute ischaemic stroke. Methods A systematic review of all the relevant randomized controlled trials (RCTs) was performed. RCTs were identified from the Cochrane Stroke Group trials register, Embase (1980 to 1997), handsearching Japanese and Chinese journals, and personal contact with pharmaceutical companies. We included randomised and quasi-randomised trials in patients with confirmed acute ischaemic stroke comparing different doses of a thrombolytic agent, or different thrombolytic agent, or the same agent given by different routes. Results Eight trials involving 1 334 patients were included. Concealment of allocation was generally adequate. All the trials were conducted in Japan. Different doses (of tissue plasminogen activator or urokinase) were compared in six trials. Different agents (tissue plasminogen activator versus urokinase,or tissue-cultured urokinase versus conventional urokinase) were compared in three trials. Few data were available for functional outcomes. A higher dose of thrombolytic therapy was associated with a five-fold increase in fatal intracranial haernorrhages (odds ratio 5.02, 95% confidence interval 1.56 to 16.18). There was a non-significant trend towards more early deaths or clinically significant intracranial haemorrhages in higher dose group. No difference in late deaths or extra-cranial haemorrhages was shown between low and higher doses. However, very few of these events occurred. No difference was shown between the different thrombolytic agents tested. Conclusions There is not enough evidence to conclude whether lower doses of thrombolytic agents might be safer or more effective than higher doses in acute ischaemic stroke. It is not possible to conclude whether one agent might be better than another, or which route of administration might be best.
Objective To explore the correlation between interleukin-6 (IL-6) 174G/C polymorphism and ischemic stroke risks. Methods Systematic searches of electronic databases as CBM, CNKI, PubMed, MEDLINE and EMbase were performed. Meta-analysis was conducted by using RevMan 5.1.2 and Stata 11.0 software. The pooled odds ratios (ORs) with 95% confidence intervals (95%CIs) were performed. Publication bias was tested by funnel plot, Egger’s regression test and Begg’s test. Sensitivity analysis was made by repeating the fixed effects model or random effects model Meta-analysis with each of the studies individually removed. Results A total of 11 publications with 12 studies were identified. The results of meta-analyses showed no significant difference was found in the correlation between IL-6 174G/C polymorphism and ischemic stroke risks (for G/C vs. G/G: OR=0.98, 95%CI 0.78 to 1.24; for C/C vs. G/G: OR=0.75, 95%CI 0.38 to 1.50; for dominant inheritance model: OR=0.93, 95%CI 0.68 to 1.28; for recessive inheritance model: OR=0.80, 95%CI 0.45 to 1.42). In the subgroup analyses on ethnicity, no significant correlation was found. But in the subgroup analyses on source of control population, the hospital-based subgroup showed IL-6 174G/C polymorphism was the protective factor of ischemic stroke (for G/C vs. G/G: OR=0.56, 95%CI 0.40 to 0.79; for C/C vs. G/G: OR=0.17, 95%CI 0.11 to 0.27; for dominant inheritance model: OR=0.40, 95%CI 0.29 to 0.55; for recessive inheritance model: OR=0.24, 95%CI 0.16 to 0.37). Conclusion Meta-analysis bly suggests that the correlation between IL-6 174 G/C polymorphism and ischemic stroke is not significantly different.
This article investigates the role of AMP-activated protein kinase (AMPK) and its downstream signaling targets in mediating cellular processes such as autophagy, apoptosis, and inflammation, offering insights into how acupuncture may treat common central nervous system (CNS) diseases, including ischemic stroke, spinal cord injury, Parkinson disease, and Alzheimer disease. AMPK and its downstream effectors are pivotal in the signaling pathways that underlie the pathophysiology of CNS diseases. These pathways are implicated in a variety of cellular responses that contribute to the progression of neurological disorders. During CNS injury, AMPK can be activated through phosphorylation, triggering the regulation of downstream molecules and exerting protective effects on neuronal function. Acupuncture has been shown to promote neuroprotection and enhance recovery in CNS diseases through multiple mechanisms, one of which involves the activation of AMPK-related signaling pathways. Nevertheless, numerous unresolved challenges remain in this research field.
Objective To investigate the relationship between Oxfordshire community stroke project (OCSP) classification and MRI classification in acute cerebral infarction. Methods A total of 282 patients with acute cerebral infarction were retrospectively evaluated with OCSP classification and imaging characteristics. Results According to OCSP classification, of all 282 patients with acute cerebral infarction, 32 (11.3%) experienced total anterior circulation infarction (TACI), 86 (30.5%) partial anterior circulation infarction (PACI), 111 (39.4%) lacunar infarction (LACI), and 53 (18.8%) posterior circulation infarction (POCI). The consistency was found in 201 cases (71.3%) between the OCSP classification and imaging classification, with the accuracy of 77% (27/35) for TACI, 79% (42/53) for PACI, 69% (95/137) for LACI and 65% (37/57) for POCI. Conclusion OCSP classification can predict the location and size of cerebral infarction with a high accuracy, and is well consistent with the MRI findings.
Progressive ischemic stroke is one of the major diseases damaging the health of Chinese people. Its pathogenesis is complex and there are many influencing factors, but the treatment methods are limited. In recent years, the rapid development of neuroimaging and the results of various clinical trials have been reported in succession, which have made new progress in the clinical diagnosis and treatment of progressive ischemic stroke. This paper summarizes the progress of progressive ischemic stroke, introduces its pathogenesis (including increased intracranial pressure and reduced perfusion pressure, thrombosis progression, hemorrhagic transformation, cerebral edema, and inflammatory response), influencing factors, predictive indicators (including image indicators, biochemical indicators, and molecular biology indicators) and treatment (including admission to “stroke unit”, intravascular treatment, platelet aggregation inhibition treatment, anticoagulation treatment, and general treatment), to provide references for preventing the occurrence and development of progressive ischemic stroke, assessing the condition, guiding treatment and improving the prognosis.
Good collateral circulation can effectively improve the prognosis of patients with severe stenosis or occlusion of cerebral blood supply artery. Studies have shown that CT angiography (CTA) can non-invasively and intuitively evaluate the degree of stenosis and collateral blood flow in diseased vessels. Rapid and accurate CTA collateral circulation score is of great significance for clinical decision-making and judging the prognosis of ischemic stroke. At present, there are many scoring scales based on CTA collateral circulation. This article will review the existing 7 CTA collateral circulation scoring scales, the advantages and disadvantages of clinical application and related research progress in predicting prognosis, aiming to provide a reference for clinicians to choose the collateral circulation score scale and the best treatment plan according to different situations.
ObjectiveTo explore the risk factors of stroke-associated pneumonia (SAP) in the patients with acute ischemic stroke, in order to provide effective guidance for clinical prevention and treatment.MethodsFrom November 2016 to November 2019, 330 patients with acute ischemic stroke admitted to the Department of Neurology of West China Hospital of Sichuan University and the Department of Neurology of the Sixth People’s Hospital of Chengdu were selected as the research object. The clinical data of the patients were analyzed retrospectively. According to whether SAP occurred, they were divided into infected group and non-infected group. Multivariate logistic regression model was used to analyze the risk factors of SAP.ResultsA total of 71 cases of SAP occurred in patients with acute ischemic stroke, accounting for 21.52%. Logistic regression analysis showed that age≥70 years old [odds ratio (OR)=3.677, 95% confidence interval (CI) (1.452, 9.311), P=0.006], chronic lung disease [OR=4.985, 95%CI (1.558, 15.952), P=0.007], disturbance of consciousness [OR=7.147, 95%CI (1.617, 31.587), P=0.009], bulbar palsy [OR=5.909, 95%CI (2.668, 13.089), P<0.001], the use of nasal feeding tube [OR=7.427, 95%CI (1.681, 32.812), P=0.008] were independent risk factors for SAP in patients with acute ischemic stroke.ConclusionsAge≥70 years old, chronic lung disease, disturbance of consciousness, bulbar paralysis and use of nasal feeding tube are independent risk factors for SAP. It is necessary to strengthen the management of these risk factors in order to identify high-risk patients with SAP early, and develop intervention strategies for risk factors, so as to improve the prognosis.
Objective To investigate the association of the polymorphism of the cystathionine β synthase (CBS) T833C, CBS 844ins68 and cerebral arterial thrombosis in Chinese population. Methods We electronically searched CBM, CNKI, Wanfang database, VIP and PubMed from 1999 to February 2010 to collect case studies on CBS polymorphism and cerebral arterial thrombosis of the Chinese. We evaluated the quality of the included studies and the extracted data. RevMan 4.2 was used for meta-analyses. Results We identified 4 case-control studies on association of CBS T833 polymorphism and cerebral arterial thrombosis of the Chinese. In Shandong subgroup, the Chinese people with TC+CC genotypes of T833C had higher risk of cerebral arterial thrombosis at OR 5.01 and 95%CI 2.63 to 9.53 (Plt;0.000 01). In non-Shandong subgroup, higher risk of cerebral arterial thrombosis was found in the Chinese people with genotype of CT+CC at OR 0.95 and 95%CI 0.60 to 1.50 (P=0.82). Meta-analyses of the 4 case studies showed there were no significant differences in the risk of cerebral arterial thrombosis between people with genotype of DI and II and people with genotype of DD at OR 1.20 and 95%CI 0.72 to 1.99 (P=0.49). Conclusion Our findings suggest that in Chinese population, CBS T833C polymorphisms might be associated with cerebral arterial thrombosis in Shandong subgroup; 844ins68 polymorphisms does not increase the risk of cerebral arterial thrombosis for the Chinese.
