ObjectiveTo explore the relevance of an increase in neutrophil count and early neurological deterioration (END) after intravenous thrombolysis in patients with acute ischemic stroke.MethodsA retrospective study was conducted on the patients who received thrombolysis treatment of alteplase within 4.5 hours after onset between January 2017 and November 2018. Based on the existence of END, the patients were divided into the END group and the non-END group. Univariate and multivariate logistic regression, and receiver operating characteristic curves were used to analyze the relevances between END and the indexes such as neutrophil count, lymphocyte count, and neutrophil to lymphocyte ratio (NLR) after thrombolysis. Paired sample t test and Wilcoxon signed-rank test were used to compare the changes of neutrophil and lymphocyte before and after thrombolysis.ResultsA total of 187 patients were included, including 48 in the END group and 139 in the non-END group. Before thrombolysis, the differences of total protein (t=2.130, P=0.035) and albumin (t=2.777, P=0.007) between the two groups were statistically significant, but the differences in other clinical indexes between the two groups were not statistically significant (P>0.05). After thrombolysis, white blood cell count, neutrophil count, NLR, fibrinase degradation product, baseline and change of National Institute of Health Stroke Scale score, proportion of cardiogenic embolism, degree of responsible vascular stenosis and anterior circulation cortical infarction site were all higher in the END group than those in the non-END group (P<0.05). The total protein, albumin, lymphocyte count and prealbumin in the END group were lower than those in the non-END group (P<0.05). Neutrophil in the END group increased significantly (Z=−2.314, P=0.021) after thrombolysis. Neutrophil count [odds ratio=1.288, 95% confidence interval (1.069, 1.552)] was one of the independent influencing factors of venous thrombolysis END, and the specificity was the highest (the sensitivity was 62.5%, and the specificity was 71.9%).ConclusionsAfter thrombolysis, elevated neutrophil count has some relevance to END. Dynamic monitoring on neutrophil count after intravenous thrombolysis treatment can predict the occurrence of END.
Objective To investigate the correlation between stress hyperglycemia ratio (SHR) and acute ischemic stroke (AIS) 1-year prognosis, to provide more clinical basis to improve the prognosis of AIS patients and to target and control the influencing factors. MethodsThe patients with AIS diagnosed for the first time and received treatment at the Shijiazhuang Fifth Hospital between May 2019 and January 2022 were retrospectively and continuously included. According to the Modified Rankin Scale score 1-year after the onset of the disease, the patients were divided into a good prognosis group and a poor prognosis group. Also the patients were divided into 2 groups based on the median of SHR. The correlation between SHR and stress blood glucose was analyzed, and the factors affecting the prognosis of AIS patients were identified. The predictive value of SHR and stress blood glucose on the prognosis of AIS patients was compared using receiver operating characteristic. Results A total of 206 patients were included. Among them, there were 125 cases (60.7%) in the good prognosis group and 81 cases (39.3%) in the poor prognosis group. The median SHR (lower quartile, upper quartile) is 1.20 (1.08, 1.33). There were statistically significant differences between the two groups in the scores of the National Institutes of Health Stroke Scale, diabetes history, hypertension history, low-density lipoprotein cholesterol, stress blood glucose, age, SHR and SHR classification (P<0.05). There was no statistically significant difference in the other indicators compared between the two groups (P＞0.05). Stress blood glucose was positively correlated with SHR (7.95±1.78 vs. 1.21±0.19; r=0.294, P<0.001). Multivariate logistic analysis showed that stress blood glucose and SHR were independent factors influencing the 1-year prognosis of AIS patients (P<0.05), and the interaction between SHR and diabetes was not significant (P>0.05) After adjusting for confounding factors, the area under the receiver operating characteristic curve of SHR for the prognosis of AIS patients was higher than that of stress blood glucose [0.682 (0.614, 0.745) vs .0.585 (0.515, 0.653); Z=2.042, P=0.041]. Conclusions SHR and stress blood glucose are independent risk factors for 1-year prognosis in AIS patients. However, SHR has a better predictive value for 1-year prognosis in AIS patients than stress blood glucose. Whether the patient has diabetes or not, the impact of SHR on the prognosis of AIS patients is consistent.
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 efficacy of systemic immune inflammation index (SII) at admission and National Institutes of Health Stroke Scale (NIHSS) score immediately after thrombolysis on evaluating the short-term prognosis of neurological function in patients with acute ischemic stroke (AIS) receiving intravenous thrombolysis. Methods Patients with AIS treated with intravenous thrombolysis in the Second People’s Hospital of Chengdu between March 2022 and March 2023 were retrospectively analyzed. The basic data of the patients, NIHSS score at emergency admission, NIHSS score immediately after thrombolysis, modified Rankin Scale (mRS) score 3 months after discharge, and laboratory data at admission were collected, and SII at admission was calculated. According to the mRS score 3 months after discharge, the patients were divided into the good prognosis group (mRS≤2) and the poor prognosis group (mRS>2). Multivariate logistic regression analysis was used to screen out the factors affecting the prognosis of patients, and the receiver operating characteristic curve was drawn to analyze the evaluation effect of SII at admission and NIHSS score immediately after thrombolysis on the poor prognosis of neurological function of patients in the short term. Results A total of 213 patients were enrolled, and the prognosis was poor in 88 patients. Multivariate logistic regression analysis showed that age, onset-to-needle time, uric acid at admission, SII at admission, fasting blood glucose after admission, and NIHSS score immediately after thrombolysis were independent risk factors for poor prognosis in AIS patients (P<0.05). The area under the receiver operating characteristic curve (AUC) of SII at admission for predicting poor prognosis was 0.715, the sensitivity was 55.7%, and the specificity was 84.0%. The AUC of NIHSS score immediately after thrombolysis for predicting poor prognosis of patients was 0.866, the sensitivity was 87.5%, and the specificity was 72.8%. The AUC of SII at admission combined with NIHSS score immediately after thrombolysis for predicting poor prognosis of patients was 0.875, the sensitivity was 84.1%, the specificity was 77.6%, the positive predictive value was 72.5%, and the negative predictive value was 87.4%. SII at admission was positively correlated with NIHSS score at emergency admission, NIHSS score immediately after thrombolysis, and mRS score 3 months after discharge (P<0.05). Conclusion SII at admission can predict the short-term prognosis of neurological function of patients with AIS after thrombolysis therapy, and the combination of SII at admission and NIHSS score immediately after thrombolysis can improve the prediction efficiency.
ObjectivesTo systematically review the efficacy and safety of nalmefene hydrochloride for acute cerebral infarction.MethodsPubMed, EMbase, The Cochrane Library, CBM, CNKI, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) on nalmefene hydrochloride for acute cerebral infarction from inception to February 21st, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 8 RCTs involving 1 038 patients were included. The results of meta-analyses showed that, compared to the routine treatment group, the nalmefene hydrochloride group was significantly associated with an increased reduction in total effective rate (RR=1.14, 95%CI 1.04 to 1.23, P=0.003), GCS (MD=1.30, 95%CI 0.66 to 1.94, P<0.0001), patient satisfaction (RR=1.26, 95%CI 1.03 to 1.55, P=0.03), cerebral blood flow (MD=5.00, 95%CI 3.81 to 6.19, P<0.05), and cerebral blood volume (MD=0.28, 95%CI 0.23 to 0.32, P<0.05). It was also significantly associated with an reduction of NIHSS, CSS, level of inflammatory factors after treatment in 14 days, level of MMP-9 and mean transit time of contrast medium (P<0.05). However, no significant association was observed between two groups in level of inflammatory factors after treatment in 20 days. For safety outcomes, no significant association was found between two groups in mortality, dizziness, and nausea and vomiting.ConclusionsThe current evidence indicates that the nalmefene hydrochloride can be used to treat acute cerebral infarction based on routine treatment of acute cerebral infarction, and the safety is relatively good. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusion.
ObjectiveTo explore the association between glycosylated hemoglobin level and poor prognosis in acute ischemic stroke (AIS) patients treated with intravenous thrombolysis.MethodsThe AIS patients treated with recombinant tissue-type plasminogen activator who were hospitalized in the Department of Neurology of the First Affiliated Hospital of Henan University of Science and Technology from September to December 2020 were retrospectively included. According to different levels of glycosylated hemoglobin, they were divided into pre-diabetic group (5.7%≤glycated hemoglobin≤6.4%), diabetic group (previously diabetic or glycosylated hemoglobin≥6.5%), and non-diabetic group (glycated hemoglobin <5.7%). The relevant information of the patients was collected, and a telephone follow-up was conducted 90 days after discharge. According to the modified Rankin Scale (mRS) score, the patients were divided into the good prognosis group (mRS score≤2) and the poor prognosis group (mRS score>2). Logistic regression analysis was used to determine the risk factors for the poor prognosis of intravenous thrombolysis in patients with AIS.ResultEventually 101 patients were included, including 44 in the non-diabetic group, 24 in the pre-diabetic group, and 33 in the diabetic group. And 64 patients were in the good prognosis group and 37 patients were in the poor prognosis group. Regression analysis results showed that diabetes was associated with poor prognosis 3 months after intravenous thrombolysis in patients with AIS [odds ratio=6.518, 95% confidence interval (1.568, 27.096), P=0.010]; and the higher the National Institutesof Health Stroke Scale score at admission was, the higher the risk of poor prognosis would be [odds ratio=1.421, 95% confidence interval (1.231, 1.640), P<0.001].ConclusionIn AIS patients who received intravenous thrombolysis, diabetes is associated with poor prognosis after 3 months.
Objective To investigate the relationship between systemic inflammation response index (SIRI) and early neurological deterioration (END) and 3-month prognosis in patients with acute ischemic stroke. Methods Patients with acute ischemic stroke treated at West China Hospital of Sichuan University and Deyang People’s Hospital between April 2020 and October 2020 were collected. Clinical data were collected using a unified case form and outcomes were followed up for 3 months. According to the poor prognosis, the patients were divided into END group and non-END group. The multivariate logistic regression analysis was used to explore the relationship of SIRI, END and 3-month prognosis. We drew receiver operating characteristic curve to evaluate the value of related factors in predicting the occurrence of END and poor prognosis after 3 months. Results A total of 242 patients were included, of which 47 (19.42%) were in the END group. There were statistically significant differences between the two groups in National Institutes of Health stroke Scale (NIHSS) score on admission, hypertension, creatinine, urea nitrogen, neutrophils count, lymphocyte count, neutrophil count/lymphocyte count ratio (NLR), lymphocyte count/monocyte count ratio, platelet count/lymphocyte count ratio, complications (besides cerebral edema) and SIRI (P<0.05). Logistic regression analysis showed that NIHSS score on admission, hypertension, SIRI and NLR were independent risk factors for END (P<0.05). SIRI had better predictive value for the occurrence of END than NLR (P<0.05). Compared with the non-END group, the patients in the END group had worse prognosis at 3-month [44.7%(21/47) vs. 17.4% (34/195), P<0.05]. NIHSS score on admission had predictive value for clinical prognosis of acute ischemic stroke patients at 3-month. Conclusion SIRI is an independent risk factor for END in patients with acute ischemic stroke, and there is no independent correlation with the 3-month prognosis.
Objective To assess the effects and safety of Tongxinluo (TXL) Capsule for patients with acute ischemic stroke. Methods PubMed (1966 to 2011.12.23), EMbase (1966 to 2011.12.23), Ovid CENTRAL (2011.10), CBM (1978 to 2011.12.23), VIP (1989 to 2011.12.23), CNKI (1980 to 2011.12.23), CDFD (1999 to 2011.12.23), and CDFD (1999 to 2011.12.23) were electronically searched for randomized controlled trials (RCTs) on TXL Capsule for patients with acute ischemic stroke. Meanwhile, relevant data were retrieved by hand search and data from pharmaceutical factories were collected. Two reviewers independently screened literature, extracted data, and assessed the methodological quality. Then, meta-analysis was performed using RevMan 5.1 software. Results Thirty nine RCTs (non-placebo-controlled trials) involving 3 906 patients were included. The quality of the included studies was generally low. The follow-up time started from the end of treatment (minimum: 7 days) to 6 months. The result of meta-analysis (16 trials, 1 445 patients) showed that the TXL group was better than the control group in improving neurological function (SMD= −1.09, 95%CI −1.68 to −0.49). The result of meta-analysis (21 trials, 2 500 patients) showed that, the effectiveness rate (91.3%) of the TXL group was significantly higher than that of the control group (RR=1.22, 95%CI 1.14 to 1.30). Eight trials reported adverse reactions such as nausea and gastric discomfort. Four trials reported that 5 patients in the control group died during the treatment. No studies reported the data of mortality, dependency rate during 3-month follow up, or quality of life. Conclusion Current studies show that, TXL Capsule improves neurological impairment of patients with acute ischemic stroke which has less adverse reactions. Further studies are still needed to verify the effects of TXL on long-term mortality and disability. It is necessary to conduct more high quality RCTs especially with placebo-controlled trials to confirm the efficacy of Tongxinluo for acute ischemic stroke.
ObjectiveTo systematically evaluate the association between red cell distribution width (RDW) and prognosis of patients with acute ischemic stroke (AIS) undergoing intravenous thrombolytic therapy.MethodsWe searched the PubMed, Embase, Cochrane Library, Web of Science, Chinese Biomedical Literature Service System, China National Knowledge Infrastructure, Wanfang database, and CQVIP database to identify eligible studies evaluating the relation between RDW and prognosis in AIS patients receiving intravenous thrombolysis from the establishment of databases to May 2021. The Newcastle-Ottawa Scale was used to evaluate the literature quality, and RevMan 5.3 software was used to process the data. The relationship between RDW and prognosis in AIS patients treated with intravenous thrombolytic therapy was analyzed using odds ratio (OR) and 95% confidence interval (CI).ResultsFive studies with a total of 1 269 participants were included into this meta-analysis. All the studies were retrospective case-control studies. Because of statistical heterogeneity (I2=59%, P=0.04), random-effects model was chosen. Meta-analysis result showed that among AIS patients who received intravenous thrombolysis, those with elevated RDW before thrombolysis were more likely to have poor prognosis than those without elevated RDW [OR=1.50, 95%CI (1.14, 1.98), P=0.004].ConclusionElevated RDW is associated with adverse outcome of AIS patients treated with thrombolysis, and may be a risk factor for poor prognosis in patients treated with thrombolytic therapy.
ObjectiveTo systematically review the efficacy and safety of Salvia miltiorrhiza injection in the treatment of acute ischemic stroke (AIS). MethodsPubMed, EMbase, The Cochrane Library, Web of Science, VIP, WanFang Data, and CNKI databases were electronically searched to collect randomized controlled trials (RCTs) on the efficacy and safety of Salvia miltiorrhiza injection in treatment of AIS from inception to February 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Network meta-analysis was then performed using Stata 16.0 software and RevMan 5.3 software. ResultsA total of 160 RCTs were included. The measures included 7 Chinese medicine injections and 8 treatment measures, covering Danhong injection combined with conventional treatment (DH+CT), Danshen injection combined with conventional treatment (DS+CT), Danshen ligustrazine injection combined with conventional treatment (DSCXQ+CT), Danshen polyphenolic acid for injection combined with conventional treatment (DSDFS+CT), compound Danshen injection combined with conventional treatment (FFDS+CT), Danshen polyphenolate for injection combined with conventional treatment (SI+CT), and Sodium Tanshinone ⅡA Sulfonate injection combined with conventional treatment (STS+CT) and conventional treatment (CT). Results of network meta-analysis showed that for the total effective rate, the rank of cumulative probability was: DSDFS+CT (93.0%) > DH+CT (80.5%) > STS+CT (66.7%) > DSCXQ+CT (66.4%) > SI+CT (50.0%)> DS+CT (26.7%)> FFDS+CT (16.7%)> CT (0.1%). In terms of NIHSS, the rank of cumulative probability was: STS+CT (95.5%) >DH+CT (80.9%)> DSCXQ+CT (70.1%) > SI+CT (64.7%) > DSDFS+CT (42.0%) > FFDS+CT (24.4%) > DS+CT (20.1%) > CT (2.4%). In the aspect of Barthel index, the rank of cumulative probability was: DH+CT (76.2%) > DSCXQ+CT (74.3%) > STS+CT (64.1%) > DSDFS+CT (62.2%) > FFDS+CT (51.8%) > SI+CT (46.0 %) > DS+CT (21.7%)> CT (3.8%). ConclusionCurrent evidence shows that, for patients with AIS, DSDFS has an improved effect on the total effective rate, while STS and DH show advantages in NIHSS score and Barthel index. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
