RESUMEN
Objective:To investigate the relationship between the degree and location of cerebral microbleeds (CMBs) and the early neurological deterioration (END) within 72 h after admissionin in patients with acute small artery occlusive stroke (SAO).Methods:Patients with first-onset SAO hospitalized in Changzhou Second People′s Hospital from July 2020 to January 2021 were retrospectively enrolled. All patients completed the head magnetic resonance imaging including susceptibility weighted imaging. Collected baseline data, and evaluated the National Institutes of Health Stroke Scale (NHISS) scores before admission and within 72 h after onset. Patients were divided into END group and no END group according to whether NIHSS scores increased by ≥3 within 72 h after admission. The baseline characteristics were compared between these two groups. Moreover, the correlation between the degree and location of CMBs and END were analyzed by multivariate Logistic regression.Results:A total of 163 first-episode SAO patients were enrolled. There were 47 patients (28.83%) with END. In END group, there were 35 patients (74.47%) with CMBs which was higher than those in non-END group [42 patients (36.21%)]. In END group, there were 21 patients (44.68%) with severe CMBs, 11 patients (23.41%) with basal ganglia CMBs, 16 patients (34.04%) with mixed CMBs, which were all higher than those in non-END group [5 patients (4.31%) with severe CMBs, 9 patients (7.76%) with basal ganglia CMBs, and 13 patients (11.21%) with mixed CMBs]. The difference was statistically significant ( P<0.05). After adjusting for triglyceride, location of infarcated lesions, and the degree of WMHs, further Logistic regression analysis revealed that severe CMBs ( OR = 6.139, 95% CI 1.377 - 27.375, P = 0.017), basal ganglia CMBs ( OR = 5.253, 95% CI 1.105 - 24.975, P = 0.037) and mixed CMBS ( OR = 5.098, 95% CI 1.197 - 21.704, P = 0.028) were independent risk factors of END in SAO patients. Conclusions:The location and degree of CMBs are closely related to the occurrence of END in patients with SAO. Severe CMBs, basal ganglia CMBs and mixed CMBs may be the effective predictors of END in patients with SAO.
RESUMEN
Objective To explore the safety and clinical efficacy of Ginkgo biloba lactone injection combined with Alteplase intravenous thrombolysis in treatment of acute ischemic stroke.Methods Totally 87 patients were recruited and divided into control group and test group.The,patients in control group (39 cases) were given Alteplase 0.9 mg/kg for injection,intravenous bolus total dose 10％ was given within 1 min,then intravenous infusion of the remaining 90％ was given in 1 h,and given basic therapy after 24 h.The 48 cases in test group,which were immediately iv Ginkgo biloba lactone injection after intravenous thrombolysis,6 mL added into 250 mL saline,once daily for 14 d,and also were given basic therapy after 24 h.All NIHSS scores were recorded before treatment,14 d and 90 d after treatment,and the adverse events were recorded.The modified Rankin scale (mRS) score and BI index were performed at 14 and 90 d after admission.Patients in two groups were classified according to the TOAST classification,and the patients with large-arteryatherosclerosis and small-artery occlusion were analyzed.Results No intracranial hemorrhage occurred in the two groups.The NIHSS score and mRS score of test group were significantly lower than that of control group,and BI index was significantly increased 90 d after treatment.The NIHSS score and mRS score of test group were significantly lower than that of control group,and BI index was significantly increased90 d after treatment of patients with large-artery atherosclerosis.But there was no significant difference between test group and control group of patients with small-artery occlusion.Conclusion Ginkgo biloba lactone injection combined with rt-PA intravenous thrombolysis in the treatment of acute ischemic stroke has high safety,and can improve the prognosis of patients.

Objective To investigate the relationship between apolipoprotein E ( ApoE ) gene polymorphism and cerebral infarction patients with different gender and etiological typing. Methods A total of 91 patients with cerebral infarction aged≥60 years ( cerebral infarction group) were enrolled. They were divided into either a large artery atherosclerotic (LAA) stroke group (n=37) or a small artery occlusion (SAO) stroke group (n=54) according to the Trial of Org 10172 in acute stroke treatment (TOAST) classification. A total of 105 age-,sex-,and residence-matched healthy subjects were enrolled as controls. A Nested Allele-Specific Multiplex Polymerase Chain Reaction Method was used to detect the ApoE gene polymorphism. The ApoE gene polymorphism of cerebral infarction of different gender and etiological typing were compared. Results ( 1 ) ApoE Genotypes of E2/2, E2/3, E2/4, E3/3, and E3/4 were detected,but the ApoE E4/4 was not detected. (2) There were no significant differences in the frequencies of ApoE genotypes and each gene carrier frequency between the cerebral infarction group and the control group (all P>0. 05). There was significant difference in ApoE genotype frequencies and each gene carrier frequency of the males between the cerebral infarction group and the control group (P0. 05). (3) There were no significant differences in the ApoE genotype frequency and gene carrier frequency among the LAA,SAO,and control groups. There was significant difference in the ApoE genotype frequency and gene carrier frequency in males between the LAA group and the control group (P>0. 01);the genotype frequencies of E2/3 and E3/E3 (6. 7% and 46. 7%),ε2,as well as theε3 carrier frequency (3. 3% and 73. 3%) of LAA were lower than those of the control group (13. 2%,79. 2%,6. 6%,and 89. 6%,respectively);the E3/4 genotype frequency andε4 carrier frequency of the LAA subtype were 46. 7% and 23. 3% respectively. They were all higher than 7. 5% and 3. 8% in the control group. However,there were no significant differences in males among the SAO group,the control group,and the 3 groups of females ( the LAA subtype,SAO subtypes,and the control group) (P>0. 05). Conclusion ε4 gene may be a risk factor for LAA in males. The association of ApoE gene polymorphism with cerebral infarction in females is not found.
