ABSTRACT
Objective:To analyze the characteristics of eye movement changes in patients with acute cerebral infarction characterized by dizziness or vertigo.Methods:The clinical data of 114 patients characterized by dizziness or vertigo in the Civil Aviation General Hospital from January 2021 to June 2022 were retrospectively analyzed. Among them, acute cerebral infarction was in 74 cases (acute cerebral infarction group), including anterior circulation infarction 32 cases, posterior circulation infarction 42 cases; benign paroxysmal positional vertigo (BPPV) was in 40 cases (BPPV group). The clinical manifestation and the results of videonystagmography (VNG) examination were recorded.Results:There were no statistical differences in the incidences of visual shaking, dysarthria and paresthesia between two groups ( P>0.05); the incidence of visual rotation in acute cerebral infarction group was significantly lower than that in BPPV group: 25.68% (19/74) vs. 100.00% (40/40), the incidence of limb weakness and walking instability were significantly higher than those in BPPV group: 29.73% (22/74) vs. 0 and 39.19% (29/74) vs. 0, and there were statistical differences ( P<0.01). The result of VNG examination showed that the abnormal incidences of eye movement and positional test in acute cerebral infarction group were significantly lower than those in BPPV group: 74.32% (55/74) vs. 100.00% (40/40) and 2.70% (2/74) vs. 100.00% (40/40), the abnormal incidences of gaze-holding test, without fixation test, randomly saccade test, smooth pursuit test and optokinetic nystagmus test were significantly higher than those in BPPV group: 10.81% (8/74) vs. 0, 21.62% (16/74) vs. 0, 45.95% (34/74) vs. 2.50% (1/40), 60.81% (45/74) vs. 5.00% (2/40) and 21.62% (16/74) vs. 0, and there were statistical differences ( P<0.01 or <0.05). There were no statistical differences in the incidences of visual rotation, visual shaking, dysarthria, walking instability and paresthesia between anterior circulation infarction patients and posterior circulation infarction patients ( P>0.05); the incidence of limb weakness in patients with anterior circulation infarction was significantly higher than that in patients with posterior circulation infarction: 50.00% (16/32) vs. 14.29% (6/42), and there was statistical difference ( P<0.01). The result of VNG examination showed there were no statistical differences in the abnormal incidences of eye movement, gaze-holding test, without fixation test, randomly saccade test, smooth pursuit test, optokinetic nystagmus test and position test between anterior circulation infarction patients and posterior circulation infarction patients ( P>0.05). Conclusions:The abnormal incidence of eye movements in patients with acute cerebral infarction is relatively high, and VNG examination can help reflect changes of the eye movement pathway in the brain.
ABSTRACT
Malignant brain edema is one of the serious complications of acute ischemic stroke, which is not uncommon after endovascular treatment, and can significantly reduce the benefits of endovascular treatment, leading to poor outcomes and even death of patients. Therefore, early identification and timely treatment are particularly important. This article reviewed the predictive factors, prevention and treatment of malignant brain edema in patients with acute ischemic stroke who received endovascular treatment.
ABSTRACT
Objective To conduct the calibration and comparative analysis on the Mindray BC 5800 automated hematology analy-zer in our department for ensuring the traceability and consistency of experimental results .Methods The mating calibrator of the Mindray company was used to conduct the calibration in the Mindray BC5800 automated hematology analyzer ,after calibration ,the calibration verification was performed .After passing the calibration verification ,the fresh blood was conduct the fixed value ,then the Mindray BC5800 and BC5180 automated hematology analyzers were calibrated ,after calibration ,the calibration verification was conducted ,after passing the calibration verification ,with the BC5800 as the standard instrument and BC5180 as the comparison in-strument ,the comparison experiment of fresh blood was performed .Results The Mindray BC5800 ,BC5300 and BC5180 automated hematology analyzers were passed the calibration verification after calibration ,in the comparison experiment of fresh blood ,the rela-tive deviation coincidence rates of WBC ,RBC ,Hb ,MCV ,PLT ,HCT ,MCH and MCHC between BC5800 and BC5300 and between BC5800 and BC5180 all exceeded 80% ,the comparison tests were passed .Conclusion The hematology analyzer should be per-formed the calibration verification and comparison test after calibration ,and the comparison test must be passed for ensuring the traceability of results and comparability among the test results in order to meet clinical needs .
ABSTRACT
To evaluate percutaneous trans hepatic puncture and intraluminal bleomycin injection for hepatic hemangioma, 20 patients accepted the therapy. With local anesthesia, a PTC needle was punctured into the lumen of hepatic hemangioma, and the bleomycin was injected. One time a week, and three times made a course of treatment. The total curative ratio was 100%. Fever and distension of the abdomen occurred in 25% of the patients. It is concluded that the method is a mini traumatic and effective therapy for hepatic hemangioma.
