ObjectiveTo systematically review the effectiveness and safety of intensive blood pressure lowering in intracerebral hemorrhage (ICH). MethodsRandomised controlled trials (RCTs) and quasi-RCTs about ICH patients receiving intensive blood pressure lowering were searched from PubMed, EMbase, SCIE, The Cochrane Library (Issue 2, 2013), CBM, CNKI, VIP and WanFang Data until March, 2014. Literature was screened according to the exclusion and inclusion criteria by two reviewers independently and meta-analysis was conducted using RevMan 5.2 software after data extraction and quality assessment. ResultsA total of 24 studies were included involving 6 299 patients, of which 10 were RCTs and 14 were quasi-RCTs. The results of meta-analysis showed that intensive blood pressure lowering was superior to guideline-recommended intervention in reducing 24-h hematoma expansion rates (OR=0.36, 95%CI 0.28 to 0.46, P < 0.05), 24-h hematoma expansion volume (MD=-3.71, 95%CI-4.15 to-3.28, P < 0.05) and perihematomal edema volume (MD=-1.09, 95%CI-1.92 to-0.22, P < 0.05). Meanwhile, intensive blood pressure lowering improved 21-d NIHSS score (MD=-3.44, 95%CI-5.02 to-1.87, P < 0.05). But there was no significant difference in mortality and adverse reaction between the two groups. ConclusionCurrent evidence shows that intensive blood pressure lowering could reduce hematoma expansion volume and perihematomal edema volume, which is beneficial to recovery of neurological function, but ICH patients' long-term prognosis needs to be further studied. Due to the limited quantity and quality of the included studies, high quality studies are needed to verify the above conclusion.
This study was aimed to improve the sensitivity of magnetic induction phase shift detection system for cerebral hemorrhage. In the study, a cerebral hemorrhage model with 13 rabbits was established by injection of autologous blood and the cerebral hemorrhage was detected by utilizing magnetic induction phase shift spectroscopy (MIPSS) detection method under the feature band. Sixty five groups of phase shift spectroscopy data were obtained. According to the characteristics of cerebral hemorrhage phase shift spectroscopy under the feature band, an effective method, B-F distribution, to diagnose the severity of cerebral hemorrhage was designed. The results showed that using MIPSS detection method under feature band, the phase shift obviously growed with increase of injection volume of autologous blood, and the phase shift induced by a 3-mL injection reached-7.750 3°±1.420 4°. B-F distribution could effectively diagnose the severity of cerebral hemorrhage. It can be concluded that the sensitivity of the cerebral hemorrhage magnetic induction detection system is improved by one order of magnitude with the MIPSS detection method under the feature band.
Objective To explore an approach of evidence-based treatment for acute hypertensive cerebral hemorrhage. Methods (1) Thoroughly evaluating the patient’s condition. (2) Formulating clinical problems. (3) We searched The Cochrane Library (Issue 1, 2006), Ovid EBM REVIEWS (2001 to 2006), MEDLINE (1980 to 2006) and CNKI (1994 to 2006) for evidence. (4) Assessing evidence. (5) Applying evidence. Results Total 13 relevant studies were retrieved. Results indicated that all kinds of interventions for the treatment of hypertensive cerebral hemorrhage showed different degrees of efficacy, including the Stroke Unit, blood pressure control, mannitol, hemostyptic and neuroprotective agents, promotion of blood circulation and resolving of blood stasis, stereotactic aspiration etc. However, the effects of other interventions need further validation except Stroke Units which had higher quality evidence. Based on the patient’ specific conditions, we recommended the following evidence-based treatment plan: immediate transfer to the Stroke Unit; sequential application of reptilase (within 6 h), citicoline (within 24 h), mannitol and Compound Danshen Injection (after 24 h); temporary withhold of enalapril meleate; monitoring of blood pressure, ECG, renal function and electrolytes; and if intracranial hemorrhage occurs again during the treatment, stereotactic aspiration should be applied. Conclusions Through evidence-based method, an individualized treatment plan could obviously improve the treatment effectiveness and reduce the incidence of adverse effects in patients with hypertensive cerebral hemorrhage.
ObjectiveTo conduct an objective record of stroke patient’s retinal diseases by retinal photography, and analyze the incidence of various retinal diseases between different subtypes of stroke.MethodsFrom June to October 2007, the consecutive cases of stroke admitted to the Department of Neurology, West China Hospital of Sichuan University were prospectively registered. Ischemic stroke patients were classified into different subtypes by the Oxfordshire Community Stroke Project criteria, and intracerebral hemorrhage (ICH) patients were classified based on the clinical manifestation and neuroimaging. We collected other clinical data associated with the incidence of stroke. The retinal abnormalities including retinopathy, arteriovenous nicking and arteriolar narrowing were recorded. Multivariate logistic regression was performed to investigate the relationship between retinal abnormalities and stroke.ResultsThis study included 199 patients with ischemic stroke and 95 patients with ICH. Among the patients with ischemic stroke, 43 (21.6%) had retinopathy, 52 (26.1%) presented with arteriovenous nicking, and 43 (21.6%) developed arteriolar narrowing. Among the patients with ICH, retinopathy occurred in 23 (24.2%), arteriovenous nicking occurred in 14 (14.7%), and arteriolar narrowing occurred in 25 (26.3%). In multivariate analysis, retinopathy was independently associated with partial anterior circulation infarct (PACI) (P=0.029) and anterior ICH (P=0.041).ConclusionsRetinopathy is independently associated with PACI and anterior ICH. Further community-based study with large sample should be conducted to confirm the predictive value of retinal diseases on the incidence of anterior stroke.
ObjectiveTo explore and compare the therapeutic effects of neuro-endoscopic and craniotomic hematoma evacuation for hypertensive hematomas in the basal ganglia region. MethodsEighty-six patients with hypertensive hematomas in the basal ganglia regions treated between January 2010 and September 2014 were divided into neuro-endoscopy and craniotomy groups randomly with 43 in each. Hematoma was removed directly under neuro-endoscope in the endoscopic group, while it was removed under the operating microscope in the craniotomy group. The average operation bleeding amount, residual hematoma after operation, hematoma evacuation rate, the changes of National Institutes of Health Stroke Scale (NIHSS) and Barthel index (BI) scores before operation, 1 and 3 months after operation were compared between the two groups. All data were analyzed statistically. ResultsThe average amount of operation bleeding was (127±26) mL, postoperative residual hematoma was (6±4) mL, and the hematoma clearance rate was (86±9)% in the neuro-endoscopy group, while those three numbers in the craniotomy group were respectively (184±41) mL, (11±6) mL, and (72±8)%, with all significant differences (P < 0.05). The NIHSS and BI scores were not significantly different between the two groups before surgery (P > 0.05). Seven days, one month and three months after surgery, the NIHSS score was significantly lower, and the BI score was significantly higher in the neuro-endoscopy group than the craniotomy group (P < 0.05). ConclusionNeuro-endoscopic surgery for hypertensive hematomas in basal ganglia region is proved to have such advantages as mini-invasion, direct-vision, complete clearance and good neural function recovery after surgery, which is a new approach in this field.
Objective To investigate the clinical characteristics and risk factors of immature hematomas in patients with primary intracerebral hemorrhage. Methods Patients with primary intracerebral hemorrhage who admitted in West China Hospital of Sichuan University between March 2012 and January 2021 were retrospectively analyzed. Brain CT scan was used to evaluate the presence of immature hematomas, as well as hematoma volume and the morphological features such as the number of hematoma projections or satellite foci, and finger-like projections. Imaging markers of cerebral small vessel disease such as lacunes, microbleeds, white matter hyperintensities (WMH), and enlarged perivascular space were evaluated on MRI. Mature hematomas were defined when the hematomas were completely homogeneous, without any irregularity or hypodensity, otherwise the hematomas were regarded as immature. Patients were divided into two groups: mature hematomas and immature hematomas. Multivariate Logistic regression was used to analyze the risk factors of immature hematomas. Results A total of 170 patients were included. Among them, there were 121 males (71.2%). The average age was (60.9±13.3) years old, and 129 cases (75.9%) had immature hematomas. The comparison between the mature hematomas group and the immature hematomas group showed that higher admission National Institutes of Health Stroke Scale score, larger hematoma volume, hematoma volume >30 mL, more hematoma projections or satellite foci, lower incidence of round or oval hematomas, cerebral small vessel disease score, lower WMH burden, and lower burden of cerebral small vessel disease were associated with the occurrence of immature hematomas. The results of multiple logistic regression analysis showed that lower incidence of round or oval hematomas, lower incidence of WMH, and lower periventricular WMH scores were associated with the occurrence of immature hematomas after adjusting for age, gender, hypertension, diabetes, smoking, alcohol consumption, admission National Institutes of Health Stroke Scale score, and hematoma volume. Conclusion Lower incidence of round or oval hematomas and lower periventricular WMH burden are associated with immature hematomas.

Methods: Intracerebral hemorrhage was induced in rats by injection of bacterial collagenase into the caudate nucleus. Histopathological changes were studied in 6 h,12 h, 24 h, 2 d, 3 d, 5 d, 7 d after the injection. The immunohistochemistry and TUNEL analysis were performed. The expression of complement factor C3, the TUNELpositive cells, the proapoptotic gene expression (Bax) and the antiapoptotic gene (Bclxl) were examined. Results: The expression of C3 increased to its maximum between 2448 h. The TUNELpositive cells and Bax protein expression increased gradually and reached the peak level between 4872 h. The Bclxl protein reached the peak level at 48 h. The correlation analysis showed that the quantity of C3 was positively related to that of the TUNELpositive cells, but the bax protein was not related to Bclxl protein. Conclusion: The expression of complement factor C3 may contributes to the nerve injury after cerebral hemorrhage and relate to the apotosis in the tissues surrounding the hametoma in rats.
Objective To analyze the value of serum levels of miR-141-3p, miR-130a, miR-29a-3p, and miR-210 in predicting early neurological deterioration (END) in non-traumatic intracerebral hemorrhage. Methods The patients with non-traumatic cerebral hemorrhage who met the selection criteria and were admitted to Chengde Central Hospital between February 2021 and October 2022 were prospectively selected by convenience sampling method. The serum miR-141-3p, miR-130a, miR-29a-3p, and miR-210 levels upon admission and the occurrence of neurological deterioration within 24 h were collected, and the patients were divided into a deterioration group and a non-deterioration group according to whether neurological deterioration occurred. The correlation of serum miR-141-3p, miR-130a, miR-29a-3p, and miR-210 levels with the END of non-traumatic intracerebral hemorrhage and their predictive value to the END of non-traumatic intracerebral hemorrhage were analyzed. Results A total of 235 patient were enrolled. Of the 235 patients, 45 (19.1%) showed neurological deterioration and 190 (80.9%) showed no neurological deterioration. The levels of miR-141-3p and miR-29a-3p in the deteriorating group were significantly lower than those in the non-deteriorating group [(1.11±0.32) vs. (1.76±0.51) ng/mL, P<0.001; (1.19±0.31) vs. (1.71±0.51) ng/mL, P<0.001], and the levels of miR-130a and miR-210 were significantly higher than those in the non-deteriorating group [(5.13±1.11) vs. (3.82±1.03) ng/mL, P<0.001; (3.96±0.76) vs. (2.78±0.50) ng/mL, P<0.001]. Multivariate logistic regression analysis showed that serum miR-141-3p and miR-29a-3p levels were protective factors for the occurrence of END in non-traumatic intracerebral hemorrhage patients [odds ratio (OR)=0.513, 95% confidence interval (CI) (0.330, 0.798), P=0.003; OR=0.582, 95%CI (0.380, 0.893), P=0.013], and serum miR-130a and miR-210 levels were independent risk factors for that [OR=2.046, 95%CI (1.222, 3.426), P=0.007; OR=2.377, 95%CI (1.219, 4.638), P=0.011]. The area under the receiver operating characteristic curve was 0.857 [95%CI (0.760, 0.954)] in predicting the END of non-traumatic intracerebral hemorrhage by the combined probability of the serum miR-141-3p, miR-130a, miR-29a-3p, and miR-210 levels obtained by logistic regression, and the sensitivity was 86.7%, the specificity was 94.7%, the positive predictive value was 79.6%, and the negative predictive value was 96.8% according to the cut-off value of the prediction probability of the combined test. Conclusion The combined detection of serum miR-141-3p, miR-130a, miR-29a-3p, and miR-210 has a high predictive value in the occurrence of END in non-traumatic intracerebral hemorrhage patients.
The incidence, mortality, and disability rate of spontaneous intracerebral hemorrhage (SICH) are high, and its surgical and medical treatment is still controversial. With the development of micro-neurosurgical technology, minimally invasive surgery (MIS) has made great progress in the treatment of SICH. It can remove intracerebral hematoma in the early stage after SICH and minimize or eliminate secondary brain injury, which is of great significance to reducing the mortality and disability rate. For many years, due to its continuous progress, MIS has been more and more widely used in the treatment of SICH. This article mainly reviews the progress of MIS in SICH and related clinical research at home and abroad, and briefly describes several innovative techniques related to MIS, which aims to promote the exchange of clinical experience in MIS of SICH.
Objective To investigate the etiological and clinical characteristics of 1298 cases with spontaneous intracerebral hemorrhage. Methods A retrospective analysis was conducted to investigate the epidemiology and clinical characteristics of 1298 patients who suffered from spontaneous intracerebral hemorrhage and were hospitalized in Neurology Dept. of Anhui Provincial Hospital from 2005 to 2009. Results Among 1 298 patients, 822 (63.33%) were male while 476 (36.67%) were female. The constituent ratio of male and female patients was significantly different; the patients mainly suffered from spontaneous intracerebral hemorrhage in winter and spring which was commonly caused by hypertension accounting for 65.87% and was mostly happened on basal ganglia site (n=895, 68.95%). Conclusions The incidence of spontaneous cerebral hemorrhage is related with age, season and hypertension, it is very important to be prevented effectively and to well control the blood pressure.
