Analysis of mental health status and related factors in patients with acute cerebral infarction

BACKGROUND Acute cerebral infarction(ACI)is characterized by a high incidence of morbidity,disability,recurrence,death and heavy economic burden,and has become a disease of concern in global researchers.As ACI has serious effects on patients’physical status,life and economy,often causing anxiety,depression and other psychological problems,these problems can lead to the aggravation of physical symptoms;thus,it is very important to understand the factors affecting the mental health of these patients.AIM To understand the elements that affect the mental health of patients who have suffered an ACI.METHODS A questionnaire survey was conducted among patients with ACI admitted to three tertiary hospitals(Quanzhou First Hospital,Fuqing City Hospital Affiliated to Fujian Medical University,and the 900 Hospital of the Joint Service Support Force of the People’s Liberation Army of China)in Fujian Province from January 2022 to December 2022 using the convenience sampling method.ACI inpatients who met the inclusion criteria were selected.Informed consent was obtained from the patients before the investigation,and a face-to-face questionnaire survey was conducted using a unified scale.The questionnaire included a general situation questionnaire,Zung’s self-rating depression scale and Zung’s self-rating anxiety scale.All questionnaires were checked by two researchers and then the data were input and sorted using Excel software.The general situation of patients with ACI was analyzed by descriptive statistics,the influence of variables on mental health by the independent sample t test and variance analysis,and the influencing factors on psychological distress were analyzed by multiple stepwise regression.RESULTS The average age of the 220 patients with ACI was 68.64±10.74 years,including 142 males and 78 females.Most of the patients were between 60 and 74 years old,the majority had high school or technical secondary school education,most lived with their spouse,and most lived in cities.The majority of patients had a personal income of 3001 to 5000 RMB yuan per month.The new rural cooperative medical insurance system had the largest number of participants.Most stroke patients were cared for by their spouses and of these patients,52.3%had previously smoked.Univariate analysis showed that gender,age,residence,course of disease,number of previous chronic diseases and smoking history were the main factors affecting the anxiety scores of patients with ACI.Age,living conditions,monthly income,course of disease and knowledge of disease were the primary variables influencing the depression score in patients with ACI.The findings of multivariate analysis revealed that the course of disease and gender were the most important factors influencing patients’anxiety scores,and the course of disease was also the most important factor influencing patients’depression scores.CONCLUSION Long disease course and female patients with ACI were more likely to have psychological problems such as a high incidence of emotional disorders.These groups require more attention and counseling.

Effects of Intravenous Thrombolytic Therapy with Alteplase on Neurological Function,Coagulation Function and Serum Inflammatory Factors in Patients with Acute Cerebral Infarction

Objective:To investigate the effects of intravenous thrombolysis therapy with alteplase on neurological function,coagulation function and serum inflammatory factors in patients with acute cerebral infarction.Methods:A total of 96 patients with acute cerebral infarction admitted to our hospital from September 2017 to October 2019 were randomly divided into two groups,with 48 patients in each group.The control group(n=48)received routine treatment,and the observation group received intravenous thrombolysis therapy with alteplase on the basis of routine treatment.The neurological deficit score,prothrombin time(PT),activated partial thromboplastin time(APTT),tumor necrosis factor-a level(TNF-α),and high-sensitivity C-reactive protein(hs-CRP)were compared between the two groups after 15 days of treatment.Results:After treatment,NIHSS scores in both groups were lower than those before treatment;PT levels were increased,while APTT,TNF-αand hs-CRP levels were all decreased in both groups,and the changes in the observation group were greater than those in the control group,with statistically significant difference(P<0.05).Conclusions:Intravenous thrombolysis therapy with alteplase can improve the neurological function,coagulation function and serum levels of inflammatory factors in patients with acute cerebral infarction,which is worthy of clinical application.

Risk factors and ankle brachial indexes in cerebral infarction combined with peripheral arterial disease

BACKGROUND: Ankle brachial index (ABI) is widely involved in researches and clinical application of peripheral vascular injury of patients with diabetes mellitus (DM); however, the application in cerebral infarction (CI) is rare. OBJECTIVE: To investigate the possible risk factor of cerebral infarction plus peripheral arterial disease (PAD), compare metabolic characteristics of patients who having CI plus PAD or only having CI, and understand the significance of ABI on screening and diagnosing CI plus PAD of lower limb. DESIGN: Contrast observation based on CI patients. SETTING: Department of Neurology, Nanxishan Hospital of Guangxi Zhuang Autonomous Region. PARTICIPANTS: A total of 124 CI patients were selected from Department of Neurology, Nanxishan Hospital of Guangxi Zhuang Autonomous Region from July 2005 to April 2006, including 72 males and 52 females aged from 45 to 88 years. All patients met the diagnostic criteria of cerebrovascular disease established by National Academic Conference of Cerebrovascular Diseases in 1995 and determined as cerebral infarction with MRI or CT examination. All patients provided informed consent. There were 46 cases (37.2%) with CI plus PAD and 78 cases (62.8%) only with CI. METHODS: Blood pressure of bilateral ankles and upper extremities was measured at plain clinostatism with DINAMAP blood pressure monitor (GE Company). The ratio between average systolic pressure of lateral ankle and average systolic pressure of both upper extremities was regarded as ABI. The normal ABI was equal to or more than 0.9. If ABI < 0.9 occurred at one side, patients were diagnosed as PAD. On the second morning after hospitalization, blood was collected to measure fasting blood glucose (FBG), 2-hour postprandial blood glucose (PBG2h), glycosylated hemoglobin (HbA1c), triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). Among them, blood glucose, lipid and other biochemical markers were measured with enzyme chemistry assay and HbA1c was measured with HbA1c meter based on high liquid phase. Measurement data and enumeration data were compared with t test and Chi-square test, and multiple factors were dealt with Logistic regression analysis and multivariate linear regression analysis. MAIN OUTCOME MEASURES: Results of correlation between ABI and metabolic markers with multivariate linear regression analysis; risk factors of CI plus PAD with Logistic regression analysis; comparisons of metabolic markers between PAD and non-PAD patients. RESULTS: All 124 patients with acute CI were involved in the final analysis. ① Comparisons of metabolic markers: Levels of serum LDL-C and uric acid (UA) were higher of PAD patients than those of non-PAD patients (t =2.051 9, 3.339 1, P < 0.05); however, there were no significant differences among other metabolic markers (P > 0.05). ② Results of multivariate linear regression analysis: PBG2h, LDL-C and UA were obvious correlation with ABI of posterior tibial artery of lower limb and dorsal pedis artery (partial regression coefficient = -0.231 to -1.010, P < 0.05). ③ Risk factors of CI plus PAD with Logistic regression analysis: Age, smoking history, sum of CI focus (≥3) and LDL-C were independent risk factor of CI plus PAD (OR =1.524-5.422, P < 0.05-0.01). CONCLUSION: ① Levels of serum LDL-C and UA of patients with CI plus PAD are high. ② ABI of lower limbs is correlation with PBG2h, LDL-C and UA. In addition, measuring ABI is beneficial for early diagnosing PAD of lower limbs of patients who have poorly controlled blood glucose, abnormal lipid and poor renal function. ③ Age, LDL-C and sum of CI focus (≥3) are independent risk factors of CI plus PAD. It is of significance for screening non-PAD patients to evaluate risk degrees and prognosis and select therapeutic methods based on ABI measurement.

Risk Factors for Prevention Stroke (IS or TIA) Due to Cerebral Infarction in Young Adults: A Meta-Analytical Study

Ischemic strokes (IS), also referred to as cerebral ischemia or brain ischemia, is a significant cause to the brain cells damage or death. Approximately, 10% - 14% of ischemic strokes cases occurred in young adults. Hence, we conducted a meta-analysis to find the effective interventions to prevent the best strokes caused by cerebral infarction in young adults. The search was done in different databases, including Google scholar, PubMed, Embase, Medline, Cochrane Central Register of Controlled Trials, Cochrane Database, Scopus, and Web of Science from January 2016 to April 2020, and only English published articles were considered. Our analysis included studies that stratified the risk of ischemic stroke by CHA2DS2-VASc score for patients with nonvalvular atrial fibrillation. Further, random effects model was used to estimate the summary annual rate of IS. Pooled relative risks and odds ratios, with their 95% confidence intervals, were calculated, respectively. The analysis was conducted using STATA (version 12), pooled effect sizes were calculated using the random-effects model and heterogeneity was tested for using the I2 statistic. The analysis included 13 studies. The analysis shows that diabetes, high blood pressure, ischemic heart disease, atrial fibrillation, hypercholesterolemia, alcohol consumption and smoking are significant risk factors. In Caucasian and Chinese ischemic stroke patients, the risk factor associations associated with ischemic stroke subtypes are similar. Compared to all other ischemia subtypes, diabetes is more familiar with aortic stroke, atrial fibrillation, ischemic heart disease (with obstruction), hypertension and diabetes. Our research shows that atrial fibrillation, ischemic heart disease, and hypercholesterolemia are low in patients with ischemic stroke and the risk factors are higher. Further analysis of each patient’s data is required to enable confounders’ adjustments to confirm and expand these findings.

Hypoxic preconditioning stimulates angiogenesis in ischemic penumbra after acute cerebral infarction

Previous studies have demonstrated the protective effect of hypoxic preconditioning on acute cerebral infarction, but the mechanisms underlying this protection remain unclear. To investigate the protective mechanisms of hypoxic preconditioning in relation to its effects on angiogenesis, we in- duced a photochemical model of cerebral infarction in an inbred line of mice （BALB/c）. Mice were then exposed to hypoxic preconditioning 30 minutes prior to model establishment. Results showed significantly increased vascular endothelial growth factor and CD31 expression in the ischemic penumbra at 24 and 72 hours post infarction, mainly in neurons and vascular endothelial cells. Hypoxic preconditioning increased vascular endothelial growth factor and CD31 expression in the ischemic penumbra and the expression of vascular endothelial growth factor was positively related to that of CD31. Moreover, hypoxic preconditioning reduced the infarct volume and improved neu- rological function in mice. These findings indicate that the protective role of hypoxic preconditioning in acute cerebral infarction may possibly be due to an increase in expression of vascular endothelial growth factor and CD31 in the ischemic penumbra, which promoted angiogenesis.

Changes of serum high sensitive C-reactive protein in patients with acute cerebral infarction

BACKGROUND： Serum high sensitive C-reactive protein （hs-CRP）, which regards as a high sensitive mark of systemic inflammatory response syndrome, can provide a lot of valuable information for the treatment and prognosis of cerebrovascular disease. OBJECTIVE： To observe the differences of blood glucose, lipid, homocysteine and previous disease history among patients with acute cerebral infarction at various levels of hs-CRP and compare changes of hs-CRP of patients with various degrees of neurologic impairment. DESIGN： Contrast observation. SETTING： Department of Neurology, Shenzhou Hospital, Shenyang Medical College. PARTICIPANTS： A total of 102 patients with acute cerebral infarction were selected from Department of Neurology, Shenzhou Hospital of Shenyang Medical College from February 2005 to September 2006, including 55 males and 47 females aged from 55 to 86 years. All accepted patients met the diagnostic criteria of cerebral infarction established by the Fourth National Cerebrovascular Disease Academic Meeting and were diagnosed with CT or MRI examination. All patients provided the confirmed consent. Based on clinical criteria of neurologic impairment established by the Fourth National Cerebrovascular Disease Academic Meeting, patients were randomly divided into mild group （0 - 15 points, n =46）, moderate group （16 - 30 points, n =38） and severe group （31 - 45 points, n =18）. In addition, based on hs-CRP level within 72 hours, patients were divided into normal group （hs-CRP ≤3 mg/L, n =53） and increasing group （hs-CRP 〉 3 mg/L, n =-49）. METHODS： ① 2 mL venous blood was selected from hospitalized patients in the next morning to separate serum. Quantitative measurement of hs-CRP was dealt with Latex Enhnced Turbidimetric Immunoassay （LETIA）. ②Fasting venous blood was colleted from hospitalized patients in the next morning to measure numeration of white blood cells, fibrinogen, blood glucose, total cholesterol （TC）, triacylglycerol （TG）, high density lipoprotein cholesterol （HDL-C）, low density lipoprotein cholesterol （LDL-C） and homocysteine. ③Measurement data were compared with t test or analysis of variance. MAIN OUTCOME MEASURES： ①Comparisons of serum biochemical indexes among patients with various levels of hs-CRP; ②comparisons of risk factors among patients with various levels of hs-CRP; ③comparisons of levels of hs-CRP among patients with various degrees of clinical neurologic impairment. RESULTS： A total of 102 patients were involved in the final analysis. ①Plasma fibrinogen and numeration of leucocytes were more in the increasing group than those in the normal group （t =4.39, 3.54, P 〈 0.01）; while, there were no significant differences of blood glucose, TC, TG, HDL-C, LDL-C and homocysteine between the two groups （P 〉 0.05）. ② Percentage of patients with hypertension and diabetes mellitus （DM） was higher in the increasing group than the normal group （ Х^2=3.98, 4.23, P 〈 0.05）; while, percentage of patients with smoking in the increasing group was not significantly different from that of patients in the normal group （P 〉 0.05）. ③Level of hs-CRP of patients with severe neurologic impairment was higher than that of patients with moderate neurologic impairment （t =2.273, P 〈 0.05）; that of patients with moderate neurologic impairment was higher than that of patients with mild neurologic impairment （t =2.586, P 〈 0.05）; that of patients with severe neurologic impairment was obviously higher than that of patients with mild neurologic impairment （t = 4.913, P 〈 0.01）. CONCLUSION： ① With the increase of hs-CRP, plasma fibrinogen and numeration of leucocytes of patients with acute cerebral infarction is increased, especially, they are increased remarkably among patients who have history of diabetes mellitus and hypertension. ②Increase of level of hs-CRP can be regarded as one of marks to evaluate severity of acute stroke.

Serum was separated and expression quantity of miR-146a and miR-146b and contents of TNF-α, interleukin (IL)-1β, IL-6 and IL-17 were determined. Peripheral blood mononuclear cells were isolated and fluorescence intensities of TLR2, TLR4, myeloid differentiation primary response gene 88 (MyD88), interleukin-1 receptor-associated kinase 1 (IRAK-1) and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) were measured. Results:At 8th week of intervention of rosuvastatin, expression quantity of serum miR-146a [(0.762 ± 0.092)vs. (0.346 ± 0.053)] and miR-146b [(0.714 ± 0.088)vs. (0.317 ± 0.047)] in patients with acute cerebral infarction was significantly higher than those before the intervention. Fluorescence intensities of peripheral blood mononuclear cells such as TLR2 [(10.34 ± 1.27)vs. (16.94 ± 1.94)], TLR4 [(11.37 ± 1.54)vs. (24.35 ± 3.26)], IRAK [(9.34 ± 0.92)vs. (15.32 ± 1.82)], MyD88 [(4.42 ± 0.56) vs. (9.41 ± 1.03)] and NF-kB [(6.65 ± 0.78) vs. (13.49 ± 1.76)] and contents of inflammatory factors such as TNF-α [(64.26 ± 8.29) μg/L vs. (106.39 ± 13.84) μg/L], IL-1β [(37.91 ± 5.24) μg/Lvs. (64.23 ± 8.33) μg/L], IL-6 [(34.28 ± 4.85) ng/Lvs. (82.46 ± 11.97) ng/L] and IL-17 [(56.75 ± 7.49) ng/Lvs. (98.31 ± 11.36) ng/L] of serum were all significantly lower than those before the intervention. Expression quantity of serum miR-146a and miR-146b had a negative correlation with fluorescence intensities of TLR2, TLR4, IRAK, MyD88 and NF-kB. Fluorescence intensities of TLR2 and TLR4 in peripheral blood mononuclear cells had a positive correlation with contents of TNF-α, IL-1β, IL-6 and IL-17 in serum. Conclusions: Treatment with rosuvastatin can up-regulate the expression quantity of serum miR-146a and miR-146b in patients with acute cerebral infarction and further inhibit the secretion of IRAK, MyD88, NF-kB, TNF-α, IL-1β, IL-6 and IL-17 mediated by TLR2 and TLR4.
