RESUMEN
ObjectiveTo investigate the changes in cerebral blood perfusion in patients with acute cerebral infarction after taking Tongnaoyin， a traditional Chinese medicine， based on head and neck computed tomography （CT） angiography （CTA） combined with brain CT perfusion imaging （CTP）. MethodA total of 240 patients with cerebral infarction of phlegm and blood stasis syndrome treated in Jiangsu Province Hospital of Traditional Chinese Medicine from March 2018 to September 2023 were randomly divided into a control group （99 cases） and a Tongnaoyin group （141 cases）. Based on the guidelines， the control group was treated with conventional treatment such as anti-aggregation， anticoagulation， lipid-lowering and plaque stabilization， brain protection， and supportive treatment. The Tongnaoyin group was treated with Tongnaoyin of 200 mL in warm conditions in the morning and evening on the basis of the control group. Both groups underwent CTA combined with CTP within 24 hours after admission， and they were reexamined by CTA and CTP in the sixth month after admission. The degree of intracranial artery stenosis was determined according to the North American Symptomatic Carotid Endarterectomy Trial （NASCET） method. The relative cerebral blood volume （rCBV）， relative cerebral blood flow （rCBF）， mean transit time （MTT）， and time to peak （TTP） of the lesion area before and after treatment were compared. The adverse outcomes of the two groups within six months after discharge were compared. ResultCompared with the group before treatment， the degree of vascular stenosis in the Tongnaoyin group was significantly reduced， and the difference was statistically significant （Z=105.369，P<0.05）. Compared with the control group after treatment， the improvement rate of vascular stenosis in the Tongnaoyin group was higher （χ2=84.179，P<0.01）， and the curative effect was better.After treatment， the rCBV and rCBF of patients in the Tongnaoyin group were significantly increased， and the difference was statistically significant （P<0.01）. MTT and TTP showed a trend of shortening， but the difference was not statistically significant. There was no statistically significant difference in rCBV， rCBF， MTT， and TTP in the control group. Compared with those in the control group after treatment， the rCBV and rCBF in the Tongnaoyin group were significantly increased， while MTT and TTP were significantly reduced （P<0.01）. After six months of discharge， the risk of poor prognosis in the Tongnaoyin group was significantly reduced compared with the control group （P<0.05）. ConclusionTongnaoyin has a good effect on improving cerebral blood perfusion in patients with acute cerebral infarction. It can be used as an effective supplement for the conventional treatment of ischemic stroke to improve clinical efficacy.
RESUMEN
Acute cerebral infarction(ACI)has the characteristics of onset nasty and high mortality,and thus the rapid determination of the occurrence and development of ACI plays a key role in the diagnosis,treatment and prognosis of ACI patients.It has shown that the serum level of human haptoglobin(Hp)is related to ACI.In this study,surface enhanced Raman scattering(SERS)combined with immune recognition was applied to establish a quantitative analysis method for serum Hp.Firstly,the SERS substrate of silver nanoparticles was prepared on silicon wafer,and 4-mercaptobenzoic Acid(MBA)was used as a Raman probe by forming Ag—S bond and connecting it on the surface of nanoparticles.The carboxyl group of MBA was linked to amino group of self-made high-affinity antibody through forming CO—NH structure thus forming a SERS self-assembled chip of Hp(Ag/MBA/anti-Hp).Hp in serum could be specifically captured by antibodies on SERS substrate,which caused the shift of SERS characteristic peak of MBA.The results showed that there was a good linear relationship between the logarithm of Hp concentration and the SERS characteristic peak shift of MBA.The detection range was 1-1000 ng/mL(R2=0.988).The Hp concentrations in serum of 90 ACI patients were determined by this method,and the results were consistent with those of ELISA method,which proved the practicability and accuracy of this method.This method was highly specific,simple and convenient,which could realize the specific recognition and quantitative analysis of serum Hp,so as to be an effective means for clinical detection of serum Hp,thus providing a reference for the treatment and prognosis of ACI.

RESUMEN
ObjectiveTo observe and compare the electrocardiogram index， myocardial morphology， and connexin 43 （Cx43） expression of two rat models of acute cerebral infarction （ACI） due to stasis combined with toxin complicated with cerebral-cardiac syndrome （CCS）， and to provide experimental evidence for the research on the occurrence mechanism of cardiac diseases induced by ACI and the clinical diagnosis and treatment of CCS. MethodSixty SPF-grade male SD rats were randomized into six groups （n=10）： normal ， syndrome of stasis combined with toxin induced by carrageenin combined with dry yeast （CA/Y）， multi-infarct induced by micro-embolism （ME）， middle cerebral artery occlusion （MCAO）， CA/Y+ME， and CA/Y+MCAO groups. The model of syndrome of stasis combined with toxin was established by intraperitoneal injection with carrageenan （CA） at 10 mg·kg-1 on the first day and subcutaneous injection with dry yeast （Y） suspension （2 mg·kg-1） on the second day of modeling. Twenty-four hours after the modeling of ACI， the electrocardiograms （ECGs） of rats in each group were collected and the number/percentage （%） of abnormal ECG was calculated. The infarct area of the brain was evaluated by 2，3，5-triphenyltetrazolium chloride （TTC） staining， and myocardial injury was assessed by hematoxylin-eosin （HE） staining. Immumohistochemical staining and Western blot were employed to determine the expression of Cx43 in the myocardium. ResultA certain number of rats in each model group presented abnormal ECG. Compared with the normal group and CA/Y group， CA/Y+MCAO group had the highest rate of abnormal ECG （P<0.01）. Compared with the normal， CA/Y， ME， and CA/Y+ME groups， the CA/Y+ME and CA/Y+MCAO groups showed decreased amplitudes of P-wave and T-wave， shortened P-R interval， and extended Q-T interval， which were particularly obvious in the CA/Y+MCAO group （P<0.05， P<0.01） and in accordance with the cerebral infarction area and pathological changes. The expression of Cx43 was up-regulated in both CA/Y+ME and CA/Y+MCAO groups， especially in the CA/Y+MCAO group （P<0.01）. ConclusionThe two rat models of ACI due to stasis combined with toxin complicated with CCS can be used to study the mechanism of heart diseases caused by cerebrovascular diseases and the therapeutic effects of Chinese medicines with the functions of resolving stasis and detoxifying. Moreover， the CA/Y+MCAO method has higher abnormal electrocardiogram rate， severer myocardial pathological injury， and higher expression of Cx43 protein. The models can be chosen according to specific experimental purpose.
RESUMEN
Objective To analyze the epidemiological characteristics of initial acute cerebral infarction (ACI) and its correlation with meteorological factors, and to provide theoretical basis for the prevention and treatment of ACI. Methods Atotal of 308 ACI patients admitted to our hospital from 2019 to 2020 were retrospectively analyzed, and the age, gender, height, weight, complications, onset season and initial symptoms of all patients were systematically analyzed from the hospital case system. Collected during the same period of meteorological data, including: monthly average temperature (℃), monthly mean minimum temperature (℃), monthly average highest temperature (℃), monthly average diurnal range (℃), the average daily air pressure (kPa), etc., by using circular distribution analysis the season of incipient ACI onset regularity, the linear correlation analysis and multiple stepwise regression analysis of the relationship between meteorological factors and the incipient ACI onset. Results The male to female ratio of 308 patients was 1.15:1. A among of 55.84% of the patients were 65 years old or older and mainly lived in urban areas (77.27%). The main risk factors were hypertension (24.03%), followed by hyperlipidemia (24.03%). The incidence was mainly in winter (30.84%) and spring (26.62%). The first symptoms are headache, dizziness, unclear speech, followed by malignant, tinnitus, vomiting, hemiplegia, dysphagia, etc. The number of ACI cases was highest in January and December, and lowest in May and June.Linear correlation analysis showed that the number of ACI cases was negatively correlated with monthly mean air temperature, monthly mean minimum air temperature and monthly mean daily range ( r=-0.362 , -0.429, -0.374, P<0.05), and positively correlated with monthly mean air pressure ( r=0.317, P<0.05). The meteorological factors that affected the incidence of ACI were monthly mean minimum temperature, followed by monthly mean daily range (P<0.05). Conclusion Meteorological factors are the influencing factors of the incidence of initial ACI. The incidence of initial ACI is high under low temperature and high atmospheric pressure. Active intervention should be given to reduce the incidence.

Based on the grade scores of the 6 dimensions， the clinical comprehensive evaluation of Xueshuantong for injection（lyophilized） in the treatment of ACI was calculated as category B by CSC 2.0. ConclusionThe clinical value of Xueshuantong for injection（lyophilized） is good， and it is suggested that it can be directly translated into relevant policy outcomes for basic clinical medication management.
RESUMEN
ObjectiveTo explore the clinical efficacy of Huanglian Jiedutang as an adjunctive treatment for acute cerebral infarction complicated with gastric motility disorder. MethodSixty patients with acute cerebral infarction complicated with gastric motility disorder with fire toxin syndrome were randomly divided into a western medicine control group （control group） and a traditional Chinese medicine （TCM） combined treatment group （observation group）， with 30 cases in each group. The control group received basic treatment for cerebral infarction and relevant western medical symptomatic treatment based on the patients' gastrointestinal symptoms. The observation group received Huanglian Jiedutang in addition to the treatment provided to the control group. The treatment course was 7 days. Neurological deficit scores and gastrointestinal dysfunction scores were assessed in both groups before treatment and on the 4th and 7th days of treatment. Gastrointestinal electrographic parameters， serum citrulline （CIT）， and motilin （MTL） levels were measured in both groups before treatment and on the 7th day of treatment. Clinical efficacy was compared between the two groups. ResultCompared with the baseline in both groups， the neurological deficit scores and gastrointestinal dysfunction scores were significantly reduced on the 4th and 7th days of treatment （P<0.05）. The reductions in these scores were more significant on the 7th day compared with those on the 4th day of treatment （P<0.05）. On the 4th and 7th days of treatment， the observation group showed a significantly greater reduction in neurological deficit scores and gastrointestinal dysfunction scores compared with the control group （P<0.05）. On the 7th day of treatment， compared with the baseline， both groups showed a significant increase in gastric antral and gastric body electric wave amplitudes as well as serum CIT and MTL levels （P<0.05）， and there were no statistically significant differences in the frequency of gastric antral and gastric body electric waves. On the 7th day of treatment， compared with the control group， the observation group had a significant increase in gastric antral and gastric body electric wave amplitudes as well as serum CIT and MTL levels （P<0.05）， and there were no statistically significant differences in the frequency of gastric antral and gastric body electric waves. After 7 days of treatment， the total effective rate in the observation group was 90.00% （27/30）， higher than 76.67% （23/30） in the control group， but the difference was not statistically significant. ConclusionAdjunctive treatment with Huanglian Jiedutang can effectively improve the symptoms of neurological function impairment and gastrointestinal dysfunction in patients with acute cerebral infarction complicated with gastric motility disorder， increase gastric antral and gastric body electric wave amplitudes， improve gastric motility disorder， and increase serum CIT and MTL levels， thereby improving the imbalanced secretion function of the gastrointestinal tract.
RESUMEN
Objective To investigate the relationship between serum neutrophil elastase(NE),Sortilin and carotid atherosclerotic(CAS)plaque in patients with acute cerebral infarction(ACI)and its predictive value for poor prognosis.Methods A total of 155 patients with ACI admitted to Daxing Teaching Hospital of Cap-ital Medical University from December 2020 to November 2022 were selected as the study objects.According to carotid intima-media thickness(IMT),they were divided into normal IMT group,thickened group and plaque group,and 40 healthy subjects were selected as control group during the same period.The serum levels of NE and Sortilin in all groups were compared and their correlations with IMT were analyzed.ACI patients were followed up for 3 months and divided into good prognosis group and poor prognosis group.Serum NE and Sortilin levels were compared between the two groups.Multivariate Logistic regression was used to ana-lyze the risk factors of poor prognosis in ACI patients.Receiver operating characteristic(ROC)curve was used to predict prognosis.Results The levels of serum NE and Sortilin in control group,IMT normal group,thick-ened group and plaque group were increased successively(P<0.05).Pearson correlation analysis showed that serum NE and Sortilin levels were positively correlated with IMT(r=0.509,0.483,P<0.05).The incidence of poor prognosis in ACI patients was 39.35%.The proportion of diabetes mellitus,age,admission National Institutes of Health Stroke Scale(NIHSS)score,low density lipoprotein cholesterol,total cholesterol,fasting blood glucose,white blood cell count,serum creatinine,NE,uric acid(UA)and Sortilin levels in poor progno-sis group were higher than those in good prognosis group(P<0.05).Multivariate Logistic regression analysis showed that admission NIHSS score and UA,NE and Sortilin levels were independent risk factors for poor prognosis in ACI patients(P<0.05).ROC curve analysis showed that the area under the curve of serum NE,Sortilin and UA alone and combined to predict poor prognosis were 0.695,0.740,0.752 and 0.869,respective-ly.The combined prediction efficiency of serum NE,Sortilin and UA was higher than that of single detection of each indicator.Conclusion The increase of serum NE and Sortilin levels in ACI patients is positively corre-lated with CAS,and is an independent risk factor for poor prognosis in ACI patients.Detection of serum NE and Sortilin levels could help predict the short-term prognosis of ACI patients.

RESUMEN
@#Objective To analyze the relationship between the levels of thrombo-inflammatory factors and the prognosis of intravenous thrombolysis in elderly patients with acute cerebral infarction （ACI）. Methods The 197 elderly patients with ACI admitted to our hospital from December 2020 to January 2023 were selected as study subjects. According to the prognosis of patients after intravenous thrombolysis， patients were divided into a good prognosis group （n=143） and a poor prognosis group （n=54）. The clinical data of patients in the two groups were compared. Multivariate analysis was used to identify independent risk predictors of poor prognosis in patients undergoing intravenous thrombolysis. The predictive value of thrombo-inflammatory factor levels for poor prognosis of intravenous thrombolysis in elderly patients with ACI was evaluated. A restricted cubic spline model was used to analyze the dose-response relationship between the levels of thrombo-inflammatory factors and the poor prognosis of intravenous thrombolysis in elderly patients with ACI. A nomograph model was constructed， and the effectiveness of the model was verified. Bootstrap resampling was used for external verification. Results Multivariate analysis results showed that the time from onset to receiving thrombolysis， pre-treatment National Institutes of Health Stroke Scale score，Trial of ORG 10 172 in Acute Stroke Treatment typing， monocyte chemoattractant protein-1，t-PA， sCD40L， and P-selectin levels were independent influencing factors for poor prognosis of patients undergoing intravenous thrombolysis （P<0.05）. The levels of thrombo-inflammatory factors had a certain predictive value for poor prognosis of patients undergoing intravenous thrombolysis， and the value of combined detection was higher than that of individual detection（area under the curve=820）. The dose-response relationship analysis results showed that when t-PA≤60 μg/L，the risk of poor prognosis increased with increasing t-PA level （HR 1.005，95%CI 1.003-1.007， P<0.001）；when t-PA>60 μg/L，the risk of poor prognosis almost no longer increased with increasing t-PA level （HR 1.003， 95%CI 1.001-1.006，P=0.614）. The C-index of the nomograph model was 0.814 and 0.823， and the area under the receiver operating characteristic curve was 0.861 and 0.843， indicating that the prediction model had good discrimination. The calibration curve fitted well， indicating high accuracy. The threshold probability of the clinical decision curve ranged from 0.03 to 0.95 and from 0.03 to 0.97， with a high net benefit value， indicating that the method was effective， safe， reliable， and practical. Conclusion The levels of thrombo-inflammatory factors have a certain impact on the prognosis of intravenous thrombolysis in elderly patients with ACI， and have a certain predictive value. The combined detection of various factors shows a higher predictive value.

@#Objective To investigate the efficacy of salvianolic acid for injection in patients with acute cerebral infarction and its influence on inflammatory factors. Methods Two hundred patients with acute cerebral infarction admitted to our hospital from January 2019 to December 2021 were divided using a random table into control group(n=100) and study group(n=100). The control group was treated with edaravone through injection,while the study group received injection of salvianolic acid in addition to the treatment to the control group. After 14 days of treatment,the two groups were compared for the overall response rate [an effective response was defined as a ≥18% decline in the score of China Stroke Scale(CSS),a neurological function deficit scale]. The Barthel Index(BI) score,CSS score,triglyceride(TG),total cholesterol(TC),C-reactive protein(CRP),interleukin-6(IL-6),and erythrocyte sedimentation rate(ESR) before and after 14 days of treatment were determined. Results The study group had a significantly higher overall response rate than the control group(P<0.05). After 14 days of treatment,both groups showed a significantly increased BI score and a significantly decreased CSS score(all P<0.05);the study group had a significantly higher BI score and a significantly lower CSS score compared with the control group(both P<0.05). After 14 days of treatment,serum levels of TG,TC,CRP,IL-6,and ESR were significantly decreased in both groups(all P<0.05);these serum indicators were significantly lower in the study group than in the control group(all P<0.05). No obvious adverse reactions were found in either group. Conclusion Salvianolic acid for injection has significant therapeutic effects in patients with acute cerebral infarction,which can reduce inflammatory reactions with good drug safety.
