The Effect of Different Hyperbaric Oxygen Treatment Time Windows on Neurological Function and Prognosis in Acute Cerebral Infarction

Objective:To observe the effects of different hyperbaric oxygen treatment time windows on the prognosis and neurological function of acute cerebral infarction.Method:160 patients with acute cerebral infarction admitted to Xiangyang Central Hospital in Hubei Province were randomly divided into four groups,each with 40 cases,using a random number table method.According to the 2017 guidelines for the treatment of cerebral infarction,the control group received routine treatment for acute cerebral infarction;On the basis of the control group,patients in Group A received hyperbaric oxygen therapy within 48 hours of onset;Group B patients receive hyperbaric oxygen therapy within 3-6 days of onset;Group C patients receive hyperbaric oxygen therapy within 7-12 days of onset.Observe the efficacy,recurrence,and neurological function recovery of four groups of patients after treatment.Result:There was no statistically significant difference in the National Institutes of Health Stroke Scale(NIHSS)and Barthel Index(BI)scores among the four groups before treatment(P>0.05).There were statistically significant differences in NIHSS and BI scores between 14 and 30 days after treatment and before treatment(F=16.352,27.261,11.899,28.326,P<0.05).At 14 and 30 days after treatment,the NIHSS score in Group A decreased compared to the control group,Group B,and Group C,while the BI score increased compared to the control group,Group B,and Group C,with statistical significance(P<0.05).There was no statistically significant difference in NIHSS and BI scores between Group C and the control group after treatment(P>0.05).After 30 days of treatment,the total effective rate of Group A was higher than that of the control group and Group C,and the difference was statistically significant(X2=6.135,P<0.05).The one-year recurrence rate of Group A and Group B is lower than that of Group C and the control group,and the difference is statistically significant(X2=8.331,P<0.05).There was no statistically significant difference in adverse reactions among the four groups(P>0.05).Conclusion:Patients with acute cerebral infarction who receive hyperbaric oxygen therapy within 48 hours can improve neurological function and reduce the recurrence rate.The efficacy of receiving hyperbaric oxygen therapy within 7-12 days of onset is equivalent to that of not receiving hyperbaric oxygen therapy.

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.

A Case of Acute Upper Gastrointestinal Bleeding in Liver Cirrhosis Complicated by Acute Cerebral Infarction and Acute Myelitis

Background: Acute upper gastrointestinal bleeding in liver cirrhosis combined with acute cerebral infarction is uncommon in clinical work, and then combined with acute myelitis is even rarer and more complex, which poses a greater challenge to clinical diagnosis and treatment. This paper reports a case of acute upper gastrointestinal bleeding in liver cirrhosis complicated by acute cerebral infarction and acute myelitis, which be hoped to provide a reference for clinical work. Methods: We retrospectively evaluated the clinical information of a 68-year-old female admitted to the Digestive Medical Department with acute gastrointestinal bleeding and appeared limb movement disorder on the third day. Results: The patient was eventually diagnosed with acute upper gastrointestinal bleeding in liver cirrhosis complicated by acute cerebral infarction and acute myelitis. Conclusions: When patients with liver cirrhosis have abnormal neurological symptoms, in addition to liver cirrhosis-related complications, doctors need to consider cerebrovascular diseases and myelitis.

Value of Tongue Color Combined with Sublingual Microcirculation in Predicting the Severity of Mild to Moderate Acute Cerebral Infarction

Objective:To explore the value of tongue color combined with sublingual microcirculation in predicting the severity of mild to moderate acute cerebral infarction(ACI).Methods:From January to December 2022,90 patients with ACI were admitted to the Department of Neurology of Jiangsu Provincial Hospital of Integrated Traditional Chinese and Western Medicine.According to the NHISS score on the 5th day of admission,the patients were divided into mild group(35 cases)and moderate group(55 cases).The changes of tongue color and arterial lactate on the 5th day of admission were observed and monitored.Side-stream dark field imaging(SDF)was used to determine the total vascular density(TVD),perfused vascular density(PVD),perfused vascular ratio(PPV)and microvascular flow index(MFI).The multivariate logistic regression analysis was used to screen the risk factors for the severity of ACI,and the receiver operating characteristic curve(ROC)to evaluate their values in predicting ACI severity.Results:There was no significant difference in lactate between the two groups(P>0.05),and the frequency of red tongue in the mild group was higher,and the frequency of red tongue in the moderate group was significantly higher in the dark tongue group(P<0.05).The multivariate logistic regression analysis showed that PVD and PPV were independent risk factors for the severity of mild to moderate ACI(P<0.05).The ROC curve analysis showed that an area under the curve of 0.832 was achieved by the combination of PVD and PPV,which was larger than that of a single factor.Conclusion:Tongue color combined with sublingual microcirculation can be combined to predict the severity of mild to moderate ACI.

Efficacy of cattle encephalon glycoside and ignotin in patients with acute cerebral infarction: a randomized, double-blind, parallel-group, placebo-controlled study

Cattle encephalon glycoside and ignotin(CEGI)injection is a compound preparation formed by a combination of muscle extract from hea lthy rabbits and brain gangliosides from cattle,and it is generally used as a neuroprotectant in the treatment of central and peripheral nerve injuries.However,there is still a need for high-level clinical evidence from large samples to support the use of CEGI.We therefore carried out a prospective,multicenter,randomized,double-blind,parallel-group,placebo-controlled study in which we recruited 319 patients with acute cerebral infarction from 16 centers in China from October 2013 to May 2016.The patients were randomized at a 3:1 ratio into CEGI(n=239;155 male,84 female;61.2±9.2 years old)and placebo(n=80;46 male,34 female;63.2±8.28 years old)groups.All patients were given standard care once daily for 14 days,including a 200 mg aspirin enteric-coated tablet and 20 mg atorvastatin calcium,both taken orally,and intravenous infusion of 250–500 mL 0.9%sodium chloride containing 40 mg sodium tanshinone IIA sulfonate.Based on conventional treatment,patients in the CEGI and placebo groups were given 12 mL CEGI or 12 mL sterile water,respectively,in an intravenous drip of 250 mL 0.9%sodium chloride(2 mL/min)once daily for 14 days.According to baseline National Institutes of Health Stroke Scale scores,patients in the two groups were divided into mild and moderate subgroups.Based on the modified Rankin Scale results,the rate of patients with good outcomes in the CEGI group was higher than that in the placebo group,and the rate of disability in the CEGI group was lower than that in the placebo group on day 90 after treatment.In the CEGI group,neurological deficits were decreased on days 14 and 90 after treatment,as measured by the National Institutes of Health Stroke Scale and the Barthel Index.Subgroup analysis revealed that CEGI led to more significant improvements in moderate stroke patients.No drug-related adverse events occurred in the CEGI or placebo groups.In conclusion,CEGI may be a safe and effective treatment for acute cerebral infarction patients,especially for moderate stroke patients.This study was approved by the Ethical Committee of Peking University Third Hospital,China(approval No.2013-068-2)on May 20,2013,and registered in the Chinese Clinical Trial Registry(registration No.ChiCTR1800017937).

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.

Effect of Xuesaitong Soft Capsule (血塞通软胶囊) on Hemorrheology and in Auxiliarily Treating Patients with Acute Cerebral Infarction

Objective: To observe the therapeutic effect of Xuesaitong soft capsule(血塞通软胶囊, XST)and its effect on platelet counts, coagulation factor 1 (CF1) as well as hemorrheologic indexes in treating patients with acute cerebral infarction (ACI). Methods: Two hundred and four patients with ACI were assigned into two groups, the control group (n=96) and the treated group (n=108). They were all treated with conventional Western medicines, including mannitol, troxerutin, citicoline, piracetam and aspirin, while to the treated group, XST was given additionally through oral intake, twice a day, 2 capsules each time for 8 successive weeks. The clinical efficacy was evaluated according to the nerve function deficits scoring and the changes of platelet count. CF1 and hemorrheological indexes were measured before and after treatment.Results: The total effective rate was 87.0% in the treated group, and 87.5% in the control group, respectively, showing insignificant difference between them. But the markedly effective rate in the treated group ( 66.7%) was significantly higher than that in the control group (27.1%, P<0.01). The count of platelet was not changed significantly in both groups after treatment, while CF1 in them evidently lowered at the end of the 4th and 8th weeks of treatment, but showed insignificant difference between the two groups. The hematocrit, whole blood viscosity and plasma viscosity in both groups were all improved significantly after treatment, but also showed insignificant difference in comparison of the two groups. Conclusion: XST has good efficacy in auxiliary treatment of patients with ACI, though its mechanism remains to be further explored.

Effect of the Principle of Activating Blood Circulation to Break Stasis on GMP-140 and D_2 Dimer in Patients with Acute Cerebral Infarction

Objective: To explore the clinical efficacy of the principle of activating blood circulation to break stasis (ABCBS) and its influence on platelet membranous protein particle (GMP-140) and D 2 dimer (D-dimer) before and after treatment. Methods: Eighty-eight patients with blood stasis syndrome (BSS) of acute cerebral infarction (ACI) were randomly divided into two groups, both of which were treated with conventional treatment, i.e. with western medicine (WM), with Salvia injection added through intravenously dripping.One of the two groups was used as the control and the other group as the treated group who had ABCBS herbs orally taken in addition. The duration of treatment course for both groups was 3 weeks. Results: There were changes in both groups over clinical symptoms, nerve function deficit scoring and GMP-140, D-dimer, but the treated group showed significantly better than that of the control group, ( P <0.05). Conclusion: ABCBS principle could serve as an important auxiliary treating method for BSS of ACI, as it can effectively alter the blood of ACI patients which was viscous, condense, coagulant and aggregating.

Effects of acupuncture therapy on plasma neuropeptide Y levels and resuscitation in patients with very early stage acute cerebral infarction A randomized controlled study

BACKGROUND： It is known that acupuncture therapy can decrease plasma neuropeptide Y （NPY） levels in patients with cerebral infarction, but different types of acupuncture therapy used in various stages of cerebral infarction have not been evaluated. OBJECTIVE： To explore the effect of acupuncture therapy on resuscitation （Xingnao Kaiqiao） and plasma NPY levels in patients with very early stage acute cerebral infarction. DESIGN, TIME AND SETTING： This case-controlled study was performed at the Affiliated Hospital of the Medical College of the Chinese People＇s Armed Police Force between September 2004 and October 2005. PARTICIPANTS： Sixty patients with acute cerebral infarction of ≤ 6 hours were used in this study. Patients were randomly divided into an acupuncture therapy group （n = 30） and a routine treatment group （n = 30）. Another 30 healthy subjects were used as the control group. METHODS： The acupuncture therapy of Xingnao Kaiqiao used in the acupuncture therapy group was based on routine western medical treatment and was performed at bilateral Neiguan （PCG） using the twirling, reinforcing-reducing method, Renzhong （DU26） using heavy bird-pecking needling, Sanyinjiao （SPG） using reinforcing and reducing by lifting and thrusting the needle, Jiquan （HT1）, Weizhong （BL40） and Chize （LU5） using reinforcing and reducing by lifting and thrusting the needle. The acupuncture lasted for 14 days. Patients in the routine treatment group underwent routine medical treatment and no intervention was given to subjects in the control group. MAIN OUTCOME MEASURES： A 4 mL venous blood sample was obtained at different time points, i.e., immediately after hospitalization, the next morning, 7 and 14 days after treatment, to measure plasma NPY levels pre- and post-treatment using the radio-immunity method. RESULTS： The plasma NPY levels were significantly higher in both the routine treatment group and the acupuncture therapy group than in the control group pre- and post-treatment （P 〈 0.01）. In particular, the plasma NPY levels in both the acupuncture therapy group and the routine treatment group were increased 7 days post-treatment but decreased from 7-14 days post-treatment. In addition, the plasma NPY levels were significantly lower in the acupuncture therapy group than in the routine treatment group on day 7 and 14 post-treatment （P 〈 0.01）. CONCLUSION： Acupuncture therapy of Xingnao Kaiqiao can decrease plasma NPY levels in patients with very early stage acute cerebral infarction. In addition, the therapeutic effect of acupuncture with a prolonged therapy time is superior to routine treatment.

Therapeutic effect of recombinant tissue plasminogen activator on acute cerebral infarction at different times

BACKGROUND:The study aimed to compare the therapeutic effect of recombinant tissue plasminogen activator(rt-PA) on the onset of acute cerebral infarction(ACI) at different time points of the first 6 hours.METHODS:A retrospective analysis was conducted in 74 patients who received rt-PA thrombolysis treatment within 4.5 hours after ACI and another 15 patients who received rt-PA thrombolysis treatment between 4.5-6 hours after ACI.RESULTS:National Institute of Health Stroke Scale(NIHSS) scores were statistically decreased in both groups(P>0.05) at 24 hours and 7 days after ACI.There was no significant difference in modified ranking scores and mortality at 90 days after the treatment between the two groups(P>0.05).CONCLUSIONS:The therapeutic effect and mortality of rt-PA treatment in patients with ACI between 4.5-6 hours after the onset of the disease were similar to those in patients who received rtPA within 4.5 hours after the onset of this disease.Therefore,intravenous thrombolytic therapy for ACI within 4.5-6 hours after ACI was effective and safe.

Bioinformatics Study of Plasma Differentially Expressed Proteins in H-Type Hypertension with or without Acute Cerebral Infarction

Objective: To investigate the bioinformatics of differentially expressed proteins in plasma in patients with acute cerebral infarction associated with H-type hypertension. Methods: Gene chip public database (gene expression omnibus, GEO) GDS4521 chip data, in the chip in 30 cases of H patients with acute cerebral infarction with high blood pressure and age, gender, matching the 20 H hypertension patients as the research object, collects the mononuclear cells (PBMCs) is used to detect the gene chip, using the GO (gene Ontology, GO), protein function analysis tools such as KEGG, screening and analysis of enrichment of differentially expressed genes function and related signaling pathway. Results: 31 genes in PBMCs were significantly changed in h-type hypertension and H-type hypertension with acute cerebral infarction, 32 of which were increased and 2 of which were decreased. GO analysis showed that in terms of biological processes, the genes related to inflammatory response and neutrophil chemotaxis were the most. In terms of molecular function, chemokine activity-related genes are the most. KEGG signaling pathway analysis showed that the most differentially expressed genes were located in the TNF signaling pathway. Conclusion: H-type hypertension with acute cerebral infarction has a variety of functional proteins and signaling pathways changes, suggesting that inflammatory response in H-type hypertension with acute cerebral infarction recovery period may still play a role in the prognosis and reactivation of the disease.

Clinical Studies on Treatment of Acute Cerebral Infarction with Xueshuantong(血栓通)Injection

Objective: To observe the effect of Xueshuantong injection (XST,血栓通注射液) with its ingredient as Notoginseng saponin, on acute cerebral infarction (ACI) and on blood coagulation and fibri-nolysis, so as to comprehensively analyse the mechanism of XST. Methods: Fifty ACI patients were randomly divided into 2 groups, and XST group (30 patients) was treated with XST, and the control group (20 patients) given low molecular dextrose, as well as low molecular heparin calcium. The course of treatment for both groups was 15 days. The changes of effective rate, score of neurologic impairment, tissue-type plasminogen activator (tPA), inhibitor of plasminogen activator (PAI), D-D dimmer, antithrombin-III (AT-III), and fibrinogen (Fbg) were all observed. Results: The total effective rate of XST group was 73.33%, that of the control group 65. 00%. After the therapy, plasma level of tPA, ratio of tPA/PAI, and AT-III content were increased obviously, while the plasma level of PAI and D-D dimmer were decreased significantly (all P<0.01) . But there was only insignificant difference between the 2 groups (P> 0.05).Conclusion: XST injection could be effective to ACI, the mechanism of which is probably related to improving the balance between plasminogen activator and its inhibitory factor, increasing the activity of fi-brinolysin, inactivating thrombin, inhibiting platelet aggregation induced by thrombin, and decreasing blood coagulation.

Changes of auditory evoked magnetic fields in patients after acute cerebral infarction using magnetoencephalography

Auditory evoked magnetic fields were recorded from 15 patients with acute cerebral infarction and 11 healthy volunteers using magnetoencephalography.The auditory stimuli of 2 kHz pure tone were binaurally presented with an interstimulus interval of 1 second.The intensity of stimuli was 90 dB and the stimulus duration was 8 ms.The results showed that the M100 was the prominent response, peaking approximately 100 ms after stimulus onset in all subjects.It originated from the area close to Heschl’s gyrus.In the patient group,the peak latency of M100 responses was significantly prolonged,and the mean strength of equivalent current dipole was significantly smaller in the affected hemisphere.The three-dimensional inter-hemispheric difference of the M100 positions was increased in the patient group.Our experimental findings suggested that impairment of cerebral function in patients with acute ischemic stroke can be detected using magnetoencephalography with the higher spatial resolution and temporal resolution.Magnetoencephalography could provide objective and sensitive indices to estimate auditory cortex function in patients with acute cerebral infarction.

Study on differential gene expression profile of serum exosomes in patients with acute cerebral infarction

Objective To analyze the differential gene expression profile of serum exosomes in patients with acute cerebral infarction(ACI)and clarify the changes in gene expression related to cerebral infarction injury and the potential serum markers.Methods Four patients with ACI and five healthy people were enrolled in the PhaseⅠstudy.After serum isolation from peripheral blood,exosomes were extracted with exosomes kits,highthroughput detection of m RNA was performed with gene chips,and differentially expressed m RNAs were screened.Gene Ontology(GO)functional analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis were performed simultaneously.Furthermore,real-time polymerase chain reaction(q RT-PCR)was used to verify the expression levels of the screened differential m RNAs in the serum exosomes collected in PhaseⅡfrom 32 patients each in the ACI case and normal control groups.Results In the PhaseⅠstudy,there were 248 differentially expressed m RNAs(fold change≥2.0,P<0.05)among five patients in the normal control group and four patients in the case group,of which the expression of 242 was upregulated and that of six was downregulated.The results of GO functional enrichment analysis mainly included behavior regulation,cell connection,and antioxidant activity.The results of KEGG pathway enrichment analysis mainly included ribosomes,proteasomes,oxytocin signaling pathways,and oxidative phosphorylation.After researching and screening based on relevant literature,it was found that among the genes with significant differential expression,H3 F3 B m RNA may be associated with and might play an important role in ACI.The q RT-PCR method was used to detect the H3 F3 B mRNA expression in serum exosomes of 32 patients each in the normal control and case groups in PhaseⅡ;the expression was significantly higher in serum exosomes of the case group than in those of the normal control group(P<0.001).H3 F3 B mRNA expression in serum exosomes of the case group positively correlated with age,the National Institutes of Health Stroke Scale(NIHSS)score,and the maximum infarct size(P<0.05).Conclusion ACI can lead to changes in the serum exosomes mRNA expression profile,which may be closely related to the occurrence,development,and prognosis of this condition.These findings will provide direction for research on the molecular mechanism,diagnostic markers,and therapeutic targets of ACI.

Meta-analysis of the effect of Xuesaitong combined with edaravone on hemorheological indexes in patients with acute cerebral infarction

Objective:To systematically evaluate the effect of Xuesaitong injection combined with edaravone injection on hemorheology indexes in patients with acute cerebral infarction.Methods:Search CNKI,WanFang,VIP,SinoMed,PubMed,Cochrane Library and other databases,collect randomized controlled trials(RCTs)of Xuesaitong combined with edaravone in the treatment of acute cerebral infarction from the establishment of the database to November 2020,using RevMan 5.3 software Perform Meta analysis.Results:10 RCTs were included,with a total of 834 patients,417 in the experimental group and 417 in the control group.The results of Meta analysis showed that the experimental group was better than the control group in improving the whole plasma viscosity(MD=-0.73,95%CI[-0.83,-0.63],P<0.00001);in terms of improving the thrombosis coefficient,the test group is better than the control group(MD=-0.19,95%CI[-0.22,-0.15],P<0.00001);In terms of platelet aggregation rate,the test group was better than the control group(MD=-0.21,95%CI[-0.25,-0.17],P<0.00001).GRADE systematically evaluates whole plasma viscosity,thrombosis coefficient,and platelet aggregation rate,showing that the level of evidence is low or very low,and the strength of the recommendation is weak.Conclusion:Xuesaitong injection combined with edaravone injection has relatively satisfactory results in improving hemorheology indexes in patients with acute cerebral infarction,and there is no obvious safety problem.However,due to the small number of included studies and the total sample size,and the limitation of the quality of the included original studies,the results of this study need to be designed with strict,high-quality,large-sample,multi-center,and more internationally recognized clinical outcome indicators and efficacy experiments to verify,in order to obtain stronger evidence-based medicine.

Conclusion: Butyphthalide + rt-PA intravenous thrombolysis can improve the DWI characteristics, coagulation function and neurological function of patients with acute cerebral infarction.

Relationship between glutathione and malonaldehyde levels in erythrocytes and the deformation index of erythrocyte in patients at various periods following acute cerebral infarction

BACKGROUND： Glutathione, as an in vivo free radical scavenger, plays an important role in the anti-oxidation defense mechanism in patients with acute cerebral infarction. OBJECTIVE： To observe the relationship between the levels of glutathione （GSH） and malonaldehyde （MDA）, the metabolite of lipid peroxidation, in erythrocyte and deformation index of erythrocyte in patients at various periods following acute cerebral infarction. DESIGN： Controlled observation.SETTING： Qilu Hospital of Shandong University and Institute of Cerebrovascular Disease of Qingdao Medical College. PARTICIPANTS： We chose 98 inpatients with acute cerebral infarction from Department of Neurology, Qilu Hospital of Shandong University from January to December 2000 , serving as cerebral infarction group, including 50 male and 48 female, with mean age of （62±7）years. There were 23 cases found on the 1^st day after onset; 25 cases on the 3^rd day after onset; 25 cases on the 7^th day after onset; 25 cases on the 14th days after onset, and they were all confirmed by craniocerebral CT or MRI. Another 30 homeochronous inpatients with neurosis, cervical syndrome, lumbar intervertebral disc herniation and motor neuron disease were chosen as control group, including 20 male and 10 female, with mean age of （52±8）years . There was no significant difference in age and gender distribution between two groups （P 〉 0.05）. Patients in the two groups were informed of detected index.METHODS：①Ulnar venous blood was chosen from the patients who were fasted on the 1^st, 3^rd,7^th and 14^th days after onset. Deformation index of erythrocyte was measured with BL88-CKX laser diffraction erythrocyte deformeter and photographing was performed. GSH level in erythrocyte was measured with DTNB assay introduced by Beu-tler. MDA level in erythrocyte was measured with modified thiobarbituric acid colorimetric method.②At each sample collecting , according to the criteria accepted by the Fourth National Conference of Cerebrovascular Disease, intergrant of neurologic impairment 〈 15 points was regarded as mild （n=46）, 15 to 30 points as moderate （n=40）and, 〉 30 points as severe （n=12）. ③ t test was used to compare data between two groups , and linear correlation analysis was used in relationship analysis among indexes. MAIN OUTCOME MEASURES ：① Comparison of erythrocyte GSH and MDA levels and deformation index of erythrocyte at various periods between patients with acute cerebral infarction and controls. ②Correlation of erythrocyte GSH level with erythrocyte MDA level and with deformation index of erythrocyte in patients with cerebral infarction . ③ Relationship between erythrocyte GSH level and severity of disease in patients with acute cerebral infarction. RESULTS： Totally 98 patients with acute cerebral infarction and 30 controls all entered the stage of result analysis. ① Erythrocyte GSH level and deformation index of erythrocyte were lower on the 1^st, 3^rd, 7^th and 14^th days after onset in cerebral infarction group than in control group （P 〈 0.05-0.01）, and erythrocyte MDA level was significantly higher in cerebral infarction group than in control group （P 〈 0.05-0.01）. The three indexes changed most significantly on day 3 after onset in patients, and began to recover or decrease on day 7 after onset and inclined to be normal on day 14 after onset. ② Erythrocyte GSH level was significantly negatively correlated with erythrocyte MDA level in patients with acute cerebral infarction on the 1^st, 3^rd, 7^th and 14^th days after onset （r=-0.534, -0.713, -0.645, -0.656, respectively, P 〈 0.05-0.01 ） ,and significantly positively correlated with erythrocyte deformation index （t-=0.502, 0.560, 0.455, 0.504, respectively, P 〈 0.05）. ③Erythrocyte GSH level was significantly lower in moderate or severe patients with acute cerebral infarction than in mild patients[（0.215±0.088）,（0.192±0.102）, （0.281±0.090） g/L, P〈 0.05]. CONCLUSION：①Erythrocyte GSH and MDA levels and deformation index of erythrocyte change significantly on the 3^rd day following acute cerebral infarction. Index detection results gradually tended to be normal on from the 7^th day to 14^th days day after onset. ② Change of erythrocyte GSH level can reflect the severity of disease of patients with acute cerebral infarction.③Decrease of erythrocyte GSH level in patients with acute cerebral infarction is one of reasons that result in the decrease of deformation ability of erythrocyte.

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.

Meta-analysis of the clinical efficacy and safety of Urinary Kallidinogenase in the treatment of acute cerebral infarction

Objective:To evaluate the clinical efficacy and safety of Urinary Kallidinogenase for Injection in the treatment of acute cerebral infarction.Methods:PubMed,The Cochrane Library,Embase,CNKI,VIP,Wan Fang and bibliographic database of Chinese medicine were searched by computer to collect randomized controlled trials of Urinary Kallidinogenase's treatment of acute cerebral infarction.The time limit was set up until September 2019.At the same time,the references and grey literature in the literature were manually screened.Two independent researchers were screened,evaluated and extracted according to inclusion and exclusion criteria.Meta-analysis was carried out by RevMan 5.3 software.Results:A total of 17 randomized controlled trials involving 2,066 patients,including 1,033 in the experimental group,and 1,033 in the control group.meta-analysis results showed that compared with the conventional treatment,Urinary Kallidinogenase had better effect in the treatment of acute cerebral infarction[OR=3.26,95%CI(2.56,4.16),P<0.00001];the national institule of Health Stroke Scale of the Urinary Kallidinogenase group was significantly better than that of the control group.Urinary Kallidinogenase group activity of daily living scale was better than the control group[OR=21.33,95%CI(6.64,36.01),P=0.004];a total of 7 articles reported adverse reactions,including 19 cases in the trial group and 21 cases in the control group,the main adverse reactions were blood pressure drop,other symptoms were chest tightness,facial redness,dizziness fever,nausea and vomiting,arrhythmia,and no other serious adverse reactions.It can recover itself.Conclusion:the available evidence shows that Urinary Kallidinogenase can effectively improve the symptoms of neurological deficits and improve the ability of daily living in patients with acute cerebral infarction,and is safe.However,the quality of the study is limited.
