Cerebral arterial blood flow,attention,and executive and cognitive functions in depressed patients after acute hypertensive cerebral hemorrhage

BACKGROUND Intracerebral hemorrhage mainly occurs in middle-aged and elderly patients with hypertension,and surgery is currently the main treatment for hypertensive cerebral hemorrhage,but the bleeding caused by surgery will cause damage to the patient's nerve cells,resulting in cognitive and motor dysfunction,resulting in a decline in the patient's quality of life.AIM To investigate associations between cerebral arterial blood flow and executive and cognitive functions in depressed patients after acute hypertensive cerebral hemorrhage.METHODS Eighty-nine patients with depression after acute hypertensive cerebral hemorrhage who were admitted to our hospital between January 2019 and July 2021 were selected as the observation group,while 100 patients without depression who had acute hypertensive cerebral hemorrhage were selected as the control group.The attention span of the patients was assessed using the Paddle Pin Test while executive function was assessed using the Wisconsin Card Sorting Test(WCST)and cognitive function was assessed using the Montreal Cognitive Assessment Scale(MoCA).The Hamilton Depression Rating Scale(HAMD-24)was used to evaluate the severity of depression of involved patients.Cerebral arterial blood flow was measured in both groups.RESULTS The MoCA score,net scores I,II,III,IV,and the total net score of the scratch test in the observation group were significantly lower than those in the control group(P<0.05).Concurrently,the total number of responses,number of incorrect responses,number of persistent errors,and number of completed responses of the first classification in the WCST test were significantly higher in the observation group than those in the control group(P<0.05).Blood flow in the basilar artery,left middle cerebral artery,right middle cerebral artery,left anterior cerebral artery,and right anterior cerebral artery was significantly lower in the observation group than in the control group(P<0.05).The basilar artery,left middle cerebral artery,right middle cerebral artery,left anterior cerebral artery,and right anterior cerebral artery were positively correlated with the net and total net scores of each part of the Paddle Pin test and the MoCA score(P<0.05),and negatively correlated with each part of the WCST test(P<0.05).In the observation group,the post-treatment improvement was more prominent in the Paddle Pin test,WCST test,HAMD-24 score,and MoCA score compared with those in the pre-treatment period(P<0.05).Blood flow in the basilar artery,left middle cerebral artery,right middle cerebral artery,left anterior cerebral artery,and right anterior cerebral artery significantly improved in the observation group after treatment(P<0.05).CONCLUSION Impaired attention,and executive and cognitive functions are correlated with cerebral artery blood flow in patients with depression after acute hypertensive cerebral hemorrhage and warrant further study.

Time-effect relationship of acupuncture on histopathology, ultrastructure, and neuroethology in the acute phase of cerebral hemorrhage

Many clinical studies have addressed the treatment of acute cerebral hemorrhage using acupuncture. However, few studies have examined the relationship between time of acupuncture and curative effect on cerebral hemorrhage. By observing the effect of acupuncture on changes in histopathology, ultrastructure, and neuroethology in a cerebral hemorrhage model of rats, we have directly examined the time-effect relationship of acupuncture. The rat model of cerebral hemorrhage was produced by slowly injecting autologous blood to the right caudate nucleus. The experimental groups were: 3-, 9-, 24-, and 48-hour model groups; and 3-, 9-, 24-, and 48-hour acupuncture groups. The sham-operation group was used for comparison. Acupuncture was performed at the Neiguan(PC6) and Renzhong(DU26) acupoints, twice a day, 6 hours apart, for 5 consecutive days. Brain tissue changes were observed by light microscopy and transmission electron microscopy. Neuroethology was assessed using Bederson and Longa scores. Our results show that compared with the sham-operation and model groups, Bederson and Longa scores were lower in each acupuncture group, with visibly improved histopathology and brain tissue ultrastructure. Further, the results were better in the 3-and 9-hour acupuncture groups than the 24-and 48-hour acupuncture groups. Our findings show that acupuncture treatment can relieve pathological and ultrastructural deterioration and neurological impairment caused by the acute phase of cerebral hemorrhage, and may protect brain tissue during this period. In addition, earlier acupuncture intervention following cerebral hemorrhage(by 3 or 9 hours) is associated with a better treatment outcome.

Acute methanol poisoning with bilateral diffuse cerebral hemorrhage:A case report

BACKGROUND Acute methanol poisoning(AMP)is a systemic disease that mainly affects the central nervous system and is characterized by ocular damage and metabolic acidosis.If appropriate treatments are inadequate or delayed,the mortality can exceed 40%.As the most serious complication,cerebral hemorrhage is rare with reported prevalence of 7%-19%.CASE SUMMARY A 62-year-old man drank liquor mixed with 45%methanol and 35%alcohol.His vision blurred 10 h later and he fell into coma in another 9 h.Serum toxicological tests were performed immediately,and continuous renal replacement therapy(CRRT)was carried out as the lactic acid exceeded 15 mmol/L and blood pH was 6.78.In addition,the toxicological report revealed 1300.5μg/mL of methanol in serum and 1500.2μg/mL in urine.After 59 h of CRRT,the methanol level decreased to 126.0μg/mL in serum and 151.0μg/mL in urine.However,the patient was still unconscious and his pupillary light reflex was slow.Computed tomography showed hemorrhage in the left putamen.After 16 d of life support treatment,putamen hemorrhage developed into diffuse symmetric intracerebral hemorrhage.In the end,his family gave up and the patient was discharged,and died in a local hospital.CONCLUSION Cerebral hemorrhage requires constant vigilance during the full course of treatment for severe cases of AMP.

ADVANCES IN CLINICAL AND EXPERIMENTAL STUDIES ON ACUPUNCTURE TREATMENT OF ACUTE CEREBRAL HEMORRHAGE

In the present paper, the authors review recent advances in clinical and experimental studies on acupuncture treatment of cerebral hemorrhage(CH). Regarding clinical studies, the resuscitation-inducing needling maneuver, and main points of Shuigou(水沟GV 26),Baihui(百会 GV 20) and scalp-points Motor Area(MS 6), Sensory Area(MS 7), etc. are often involved. Concerning experimental studies, the underlying mechanisms of acupuncture of GV-26+“Neiguan”(内关 PC 6), GV-20,GV-26+GV-20, etc. in improving acute CH are introduced. In a word, acupuncture therapy works well in improving clinical symptoms and signs of CH patients, and acupuncture stimulation induced ameilioration of cerebral blood flow, favorable modulation of some bioactive substances as excitatory and inhibitory amino acids, endothelin, CGRP, heat shock protein 70, etc. and neuro-endocrine-immune network may contribute to the effect of acupuncture on CH. In addition, acupuncture combined with medicine and earlier application of acupuncture therapy in the acute stage of CH are recommended in clinical practice.

The Effect of Zhu Yu Hua Tan Tang on IntracranialPressure in Case of Acute Cerebral Hemorrhage

The therapeutic effect of Zhu Yu Hua Tan Tang (逐瘀化痰汤Decoction for removing blood stasis and resolving phlegm) plus general and modern treatment on acute cerebral hemorrhage in 44 cases, and the pressure-lowering effect of Zhu Yu Hua Tan Tang and mannitol in 20 cases of acute cerebral hemorrhage in the basilar region, and in rabbits with experimental encephaledema induced by injection of olive oil into the common carotid artery were observed in this study. The results showed that Zhu Yu Hua Tan Tang plus general treatment can better improved the conscious state of the patients than western medicine, and it can make the intracranial pressure drop clinically by 40.44%. The intracranial pressure-lowering effect of Zhu Yu Hua Tan Tang, though slow, is smooth and long-lasting without any rebound phenomenon, as compared to those of mannitol. Similar results were found in animal experiments, but the intracranial pressure-lowering amplitude of Zhu Yu Hua Tan Tang was stronger than that of mannitol. The difference between the clinical and experimental results needs to be further studied.

EFFECT OF ELECTROACUPUNCTURE OF SCALP-POINTS ON ABNORMAL DISCHARGES OF NEURONS AROUND THE CEREBRAL HEMORRHAGE FOCUS IN THE RAT

Objective: To study the mechanism of electroacupuncture (EA) of scalp-points for regulating abnormal discharges of neurons in different regions around the cerebral hemorrhage focus by using neuro-electrophysiological methods. Methods: 80 Wistar rats (anesthetized with 20% urethane 1 g/kg, i.p.) were randomly divided into normal, saline, model and EA groups, with 20 cases in each group. Cerebral hemorrhage model was established by intracerebral injection of the rat’s own arterial blood sample (40 uL). In rats of saline group, the same volume of saline was given for intracerebral injection. Extracellular electrical activity of neurons of the caudate nucleus and parafascicular nucleus and Tail flicking latency (TFL) were used as the indexes. “Baihui”(百会 GV 20) and “Taiyang”(太阳 EX-HN 5) were punctured from GV 20 towards EX-HN 5 with filiform needles and stimulated electrically with stimulating parameters of strength of 1 V, frequency of 15 Hz and duration of 15 min. Results: Compared with normal group, TFL values of model group and EA group increased significantly (P<0.01); and compared with model group, those of EA group decreased significantly (P<0.01), suggesting that the pain threshold increased significantly in cerebral hemorrhage rats while after acupuncture stimulation, it lowered strikingly. Compared with normal and saline groups, the latency values of the pain excitement and inhibitory responses of the cellular discharges of the caudate and parafascicular nuclei in model and EA groups increased significantly (P<0.05～0.01), while after EA, it recovered apparently (P<0.01), showing an apparent regulative effect of EA on the abnormal changes of discharges of neurons around the cerebral hemorrhage focus. Conclusion: Scalp-acupuncture possesses an apparent regulatory effect on the abnormal electrical activity of neurons around the cerebral hemorrhage focus which may favor the early recovery of functional activity of neurons near the focus tissues.

Effect of Tianhuang Granule(田黄冲剂) on Intracranial Pressure and Serum Matrix Metalloproteinase-9 in Patients with Acute Cerebral Hemorrhage

Objective： To study the effect and mechanism of Tianhuang Granule （田黄冲剂, THG） on hydrocephalus in the patients with acute cerebral hemorrhage （ACH） through intracranial pressure （ICP） monitoring, serum matrix metalloproteinase-9 （MMP-9） level observation, and National Institutes of Health Stroke Scale （NIHSS） scoring （for nerve function deficit）. Methods： Sixty patients with ACH were equally randomized into two groups by lottery, the control group and the THG group; all were treated with conventional therapy, but to the patients in the THG group, THG was given orally in addition for 28 days. Changes of ICP, MMP-9 expression, and NIHSS scores, as well as the degree of cerebral hematoma and hydrocephalus （by cranial CT scanning） in the patients, were estimated and compared. Results： （1） ICP was lowered more significantly in the THG group, showing a significant difference between groups on day 7 （P〈0.05）. （2） MMP-9 expression was down-regulated in the THG group more significantly and earlier than that in the control group. （3） The degrees of cerebral hematoma and hydrocephalus in the THG group on day 7 were reduced significantly as compared with those on day 3 （P〈0.05）, but in the control group, the day of significant reduction was delayed to day 14, and the degrees on day 7 and day 14 in the two groups were significantly different （P〈0.05 and P〈0.01）. （4） NIHSS score was significantly lower in the THG group than that in the control group on day 14 and day 28 （P〈0.05 and P〈0.01）. Conclusion： THG can effectively lower ICP, down-regulate MMP-9 expression, promote the absorption of cerebral hematoma and hydrocephalus, and improve the nerve function, showing a clinical effectiveness than conventional therapy.

Influences of blood lipids on the occurrence and prognosis of hemorrhagic transformation after acute cerebral infarction: a case-control study of 732 patients

Background: To study the influence of blood lipid levels on hemorrhagic transformation(HT) and prognosis after acute cerebral infarction(ACI).Methods: Patients with ACI within 72 h of symptoms onset between January 1 st, 2015, and December 31 st, 2016, were retrospectively analyzed. Patients were divided into group A(without HT) and group B(HT). The outcomes were assessed after 3 months of disease onset using the modified Rankin Scale(m RS). An m RS score of 0–2 points indicated excellent prognosis, and an m RS score of 3–6 points indicated poor prognosis.Results: A total of 732 patients conformed to the inclusion criteria, including 628 in group A and 104 in group B. The incidence of HT was 14.2%, and the median onset time was 2 d(interquartile range, 1–7 d). The percentages of patients with large infarct size and cortex involvement in group B were 80.8% and 79.8%, respectively, which were both significantly higher than those in group A(28.7 and 33.4%, respectively). The incidence rate of atrial fibrillation(AF) in group B was significantly higher than that in group A(39.4% vs. 13.9%, P<0.001). The adjusted multivariate analysis results showed that large infarct size, cortex involvement and AF were independent risk factors of HT, while total cholesterol(TC) was a protective factor of HT(OR=0.359, 95% CI 0.136–0.944, P=0.038). With every 1 mmol/L reduction in normal TC levels, the risk of HT increased by 64.1%. The mortality and morbidity at 3 months in group B(21.2% and 76.7%, respectively) were both significantly higher than those in group A(8.0% and 42.8%, respectively). The adjusted multivariate analysis results showed that large infarct size(OR=12.178, 95% CI 5.390–27.516, P<0.001) was an independent risk factor of long-term unfavorable outcomes, whereas low-density lipoprotein cholesterol(LDL-C) was a protective factor(OR=0.538, 95% CI 0.300–0.964, P=0.037). With every 1 mmol/L reduction in normal LDL-C levels, the risk of an unfavorable outcome increased by 46.2%. Major therapies, including intravenous recombinant human tissue plasminogen activator(r TPA), intensive lipid-lowering statins and anti-platelets, were not significantly related to either HT or long-term, post-ACI poor prognosis.Conclusions: For patients with large infarct sizes, especially those with cortex involvement, AF, or lower levels of TC, the risk of HT might increase after ACI. The risk of a long-term unfavorable outcome in these patients might increase with a reduction in LDL-C.

Study on risk factors of hemorrhagic transformation in patients with acute cerebral infarction after non thrombolysis

Objective:To study the risk factors of hemorrhagic transformation in patients with acute cerebral infarction and to analyze the risk factors.Methods: A total of 96 patients with acute cerebral infarction after the thrombolysis in our hospital from June 2016 to December 2017 were selected as the research object. And they were divided into bleeding group 48 cases and hemorrhage transformation group 48 cases according to whether with hemorrhage occurs transformation. Then the lipid metabolism, atrial fibrillation, history of smoking and drinking, history of hypertension and diabetes, blood pressure, treatment time after onset and infarction area of two groups were compared, and the relationship between those factors and the disease were analyzed by the multi-factor Logistic regression analysis.Results: The atrial fibrillation, history of smoking and drinking of two groups had significant differences;The hospital fasting plasma glucose and LDL-C level of two groups had significant differences;the treatment time after onset and infarction area of two groups had significant differences;The multi-factor Logistic regression analysis showed that atrial fibrillation, blood glucose on admission, LDL-C and large area of infarction are the factors affecting the risk of bleeding in patients with acute cerebral infarction transformation.Conclusion:Atrial fibrillation, blood glucose on admission, LDL-C, treatment time after onset and large area of infarction belongs to the patients with acute cerebral infarction after the thrombolysis transformation of bleeding risk factors.

Hydroxyethylstarch revisited for acute brain injury treatment

Infusion of the colloid hydroxyethylstarch has been used for volume substitution to maintain hemodynamics and microcirculation after e.g., severe blood loss.In the last decade it was revealed that hydroxyethylstarch can aggravate acute kidney injury, especially in septic patients.Because of the serious risk for critically ill patients, the administration of hydroxyethylstarch was restricted for clinical use.Animal studies and recently published in vitro experiments showed that hydroxyethylstarch might exert protective effects on the blood-brain barrier.Since the prevention of blood-brain barrier disruption was shown to go along with the reduction of brain damage after several kinds of insults, we revisit the topic hydroxyethylstarch and discuss a possible niche for the application of hydroxyethylstarch in acute brain injury treatment.

MRI在急性脑梗死患者血管内血栓切除术后颅内出血的预测价值

目的探讨MRI在急性脑梗死患者进行血管内血栓切除术(EVT)后颅内出血(ICH)的预测价值。方法回顾性分析接受EVT治疗的急性脑梗死患者67例,收集这些患者的弥散加权成像(DWI)、灌注加权成像(PWI)和DWI-PWI不匹配(DPM)的体积以及其他临床相关数据,ICH由非增强CT评估。采用多元logistic回归分析预测急性脑梗死患者治疗后的ICH。结果接受EVT后,ICH的患者空腹血糖[(11.96±1.93)mg/L与(13.26±1.73)mg/L]、HbA1c[(5.73±0.42)%与(6.21±0.49)%]、DWI梗死体积(51.23±41.32 ml与29.61±32.26ml)显著大于无ICH的患者(t=-7.693,P<0.001;t=6.135,P<0.001;t=-2.531,P=0.016)。多变量逻辑回归分析显示血糖[OR(95%CI):1.312(1.145~1.417),P<0.001]、HbA1c[OR(95%CI):38.847(7.216~201.753),P<0.001]以及DWI梗死体积[OR(95%CI):1.021(1.004~1.034),P=0.016]为预测急性脑梗死患者EVT术后ICH独立的预测因子。结论急性脑梗死患者行EVT治疗后,通过检测患者的空腹血糖、HbA1c和DWI梗死体积能够预测ICH的发生风险,从而对后续的临床治疗提供信息。
