Aggressive blood pressure treatment of hypertensive intracerebral hemorrhage may lead to global cerebral hypoperfusion: Case report and imaging perspective

Serum vascular endothelial growth factor and cortisol expression to predict prognosis of patients with hypertensive cerebral hemorrhage

BACKGROUND

Cerebral hemorrhage is a common and severe complication of hypertension in middle-aged and elderly men.

AIM

To investigate the correlation between vascular endothelial growth factor (VEGF) and cortisol (Cor) and the prognosis of patients with hypertensive cerebral hemorrhage.

METHODS

A hundred patients with hypertensive intracerebral hemorrhage were enrolled from January 2020 to December 2022 and assigned to the hypertensive intracerebral hemorrhage group. Another 100 healthy people who were examined at our hospital during the same period were selected and assigned to the healthy group. Peripheral venous blood was collected, and serum Cor and VGEF levels were measured through enzyme linked immunosorbent assay.

RESULTS

A statistically significant difference in serum Cor and VGEF levels was observed among patients with varying degrees of neurological impairment (P < 0.05). Serum Cor and VGEF levels were significantly higher in the severe group than in the mild-to-moderate group. Cor and VEGF levels were significantly higher in patients with poor prognoses than in those with good prognoses. Multiple logistic regression analysis revealed that serum Cor and VGEF levels were independent factors affecting hypertensive intracerebral hemorrhage (P < 0.05).

CONCLUSION

Cor and VGEF are associated with the occurrence and development of hypertensive cerebral hemorrhage and are significantly associated with neurological impairment and prognosis of patients.

Therapeutic Variation in Lowering Blood Pressure: Effects on Intracranial Pressure in Acute Intracerebral Haemorrhage

INTRODUCTION

Intracerebral haemorrhage (ICH) is associated with high morbidity and mortality. Blood pressure (BP) control is one of the main management strategies in acute ICH. Limited data currently exist regarding intracranial pressure (ICP) in acute ICH. The relationship between BP lowering and ICP is yet to be fully elucidated.

METHODS

We conducted a systematic review to investigate the effects of BP lowering on ICP in acute ICH. The study protocol was registered on PROSPERO (CRD42019134470).

RESULTS

Following PRISMA guidelines, MEDLINE, EMBASE and CENTRAL were searched for studies on ICH with BP and ICP or surrogate measures. 1096 articles were identified after duplicates were removed; 18 studies meeting the inclusion criteria. Dihydropyridine calcium channel blockers (CCBs) were the most common agent used to lower BP, but had a varying effect on ICP. Other BP-lowering agents used also had a varying effect on ICP.

DISCUSSION AND CONCLUSION

Further work, including large observational or randomized interventional studies, is needed to develop a better understanding of the effect of BP lowering on ICP in acute ICH, which will assist the development of more effective management strategies.

TRIAL REGISTRATION

The study protocol was registered on PROSPERO (CRD42019134470) on 29/05/2019.

Dl-3-n-Butylphthalide promotes neovascularization and neurological recovery in a rat model of intracerebral hemorrhage

Background

Cerebral stroke occurs following ischemic and hemorrhagic lesions in the brain. Survival and recovery of stroke patients depend on the severity of the initial injury but also the therapeutic approaches applied for emergent lifesaving and continuing post-stroke management. Dl-3-n-Butylphthalide (NBP), an active compound derived from Chinese celery seeds, has shown clinical efficacy in the treatment of ischemic cerebral stroke.

Results

In the present study we explored the therapeutic effect of NBP in a rat model of intracerebral hemorrhage (ICH), focusing on its potential role in promoting neovascularization in the perihemorrhagic zone. ICH was induced in male Sprague-Dawley rats by unilateral injection of autologous blood into the globus pallidus, with sham-operated (Sham group), vehicle-treated (ICH) and NBP-treated (at 10 and 25 mg/kg/Bid, p.o., ICH + NBP10 and ICH + NBP25, respectively) groups examined behaviorally, macroscopically, histologically and biochemically at 1, 3, 7 and 15 days (d) post operation. Rats in the ICH + NBP10 and ICH + NBP25 groups showed reduced Longa’s motor scores relative to the ICH groups at the 3 and 7d time points, while the hematoma volume was comparable in the two NBP relative to the ICH groups as measured at 7d and 15d. In the perihemorrhagic zone, the numeric density of blood vessels immunolabeled by CD34, an angiogenic marker, was greater in the ICH + NBP10 and ICH + NBP25 than ICH groups, more so in the higher dosage group, at 1, 3, 7 and 15d. Levels of the vascular endothelial growth factor (VEGF) and angiopoietins-2 (Ang-2) proteins were elevated in the NBP groups relative to the sham and vehicle controls in immunoblotting of tissue lysates from the injection region.

Conclusion

These results suggest that NBP can alleviate neurological defects following experimentally induced local brain hemorrhage, which is associated with a potential role of this drug in promoting neovascularization surrounding the bleeding loci.

Effect of rehabilitation therapy and nursing intervention on postoperative recovery of patients with hypertensive intracerebral hemorrhage

Rehabilitation therapy combined with nursing intervention in postoperative recovery of patients with hypertensive intracerebral hemorrhage was investigated. Retrospective analysis was carried out in 78 patients with severe HICH hematoma evacuation after treatment in Xuzhou No. 1 People's Hospital, Xuzhou Municipal Hospital Affiliated to Xuzhou Medical University from March 2014 to July 2017. The 28 patients who received routine treatment and nursing care were regarded as the control group, the 27 patients who underwent rehabilitation training based with routine treatment and nursing care were the rehabilitation training group. Moreover, the 23 patients who underwent rehabilitation training and nursing intervention based on routine treatment were regarded as the nursing intervention group. Systolic blood pressure, diastolic blood pressure, and Fugl-Meyer scores were compared immediately after surgery (T1), 4 weeks after treatment (T2) and 12 weeks after treatment (T3). During the period of T3, the total effective rate and adverse reactions were compared among the three groups of patients. The systolic blood pressure and diastolic blood pressure at T3 among the three groups were significantly lower than both T2 and T1, and the systolic and diastolic blood pressure of T2 was lower than T1 (P<0.05). Among the three groups of patients, the Fugl-Meyer score at T3 was significantly higher than both the T2 and T1, and the Fugl-Meyer score at T2 was higher than T1 (P<0.050). In the control group, the number of patients with shoulder-hand syndrome, hemorrhoids, and depression was significantly higher than both the rehabilitation training group and the nursing intervention group (P<0.050). The number of people with depression in the rehabilitation training group was significantly higher than the nursing intervention group (P<0.050). Rehabilitation therapy and nursing intervention are better than routine treatment and nursing for postoperative recovery of HICH patients, and has a lower adverse reaction rates after surgery, it is worthy of promotion clinically.
