In the paper, it is introduced professor HE Xingwei's recognition on the pathogenesis and professor HE's experience in the treatment of the motor impairment of the trunk after stroke. Professor He believes that the motor impairment of the trunk after stroke is the essential factor affecting the rehabilitation in stroke. The motor impairment of the trunk after stroke results from brain marrow damage and spiritual impairment. Hence, regaining the consciousness and promoting the circulation of the governor vessel are the basic principles of the treatment, named regulating the mind and controlling qi, benefiting qi and warming yang, tonifying the kidney and filling up the essence, and promoting the circulation of the governor vessel...

To explore the relativity between heart-brain and post-stroke anxiety disorder by analyzing the pathogenesis of post-stroke anxiety disorder combined with the physiology and pathology of organs. The acupoint selection thought was explored by its selection rule according to literature. Post-stroke anxiety belongs to the brain organic anxiety disorder, whose basic pathogenesis is mind injury. The crucial cause is heart and brain disorder at the same time. Thus, Baihui (GV 20), Fengfu (GV 16) for brain and Xinshu (BL 15), Shenmen (HT 7) for heart can improve anxiety disorder according to the theories such as five organ, qijie (qi thoroughfare), sihai (four seas), meridian and collateral...

Blood supply to the brain is secured by an extensive collateral circulation system, which can be divided into primary routes, i.e., the Circle of Willis, and secondary routes, e.g., collaterals from the external to the internal carotid artery and leptomeningeal collaterals. Collateral flow is the basis for acute stroke treatment, since neurones will only survive long enough to be rescued with reperfusion therapies if there is sufficient collateral flow. Poor collateral flow is associated with worse outcome and faster growth of larger infarcts in acute stroke treatment...

BACKGROUND: Secondary pallidonigral transneuronal degeneration after a remote primary cerebral infarct can mimic recurrent stroke at clinical presentation. We describe a patient with secondary pallidonigral degeneration following a previous putaminal infarct, which was diagnosed through diffusion-weighted (DWI) and T2-weighted imaging (T2WI). CASE PRESENTATION: A 64-year-old man complained of an acute relapse of right-lower-limb weakness following a cerebral infarction 2 months before presentation...

Ischemic stroke is a leading cause of human death and disability while clinical treatments are limited. The adult brain possesses endogenous regenerative activities that may benefit tissue repair after stroke. Trophic factors such as stromal cell-derived factor 1 alpha (SDF-1α) are upregulated in the ischemic brain, which promote endogenous regeneration. The regenerative response, however, is normally insufficient. Transplantation of exogenous cells has been explored as regenerative therapies. One promising cell type for transplantation is induced pluripotent stem (iPS) cells which are cells genetically reprogrammed from adult somatic cells...

Cerebral ischemic stroke is usually caused by a temporary or permanent decrease in blood supply to the brain. Despite general progress in diagnosis and treatment, the prognosis of stroke is still unsatisfactory, and more detailed potential mechanisms are needed to investigate underlying the pathological process. Here, we showed that serum angiotensin-converting enzyme (ACE) concentration was positively correlated with infarct volume after acute ischemic stroke (AIS). Moreover, using a permanent middle cerebral artery occlusion rat model, we indicated for the first time that increased ACE expression in response to AIS was regulated by the ERK/NF-κB pathway in peri-infarct regions...

OBJECTIVES: When evaluated prospectively, acute brain injury is reported in up to 75% of neonates undergoing cardiopulmonary bypass (CPB), predominantly white matter injury rather than stroke. This study investigates the incidence of stroke (focal infarct and/or haemorrhage) detected by neuroimaging in contemporary clinical practice, whereby magnetic resonance imaging/computed tomography routinely occurs in response to clinical events, comparing those undergoing the Norwood procedure with those undergoing other neonatal procedures involving CPB, and defines the relationship between stroke and neurodevelopmental disability (NDD) at 12 months of age...

A mild non-lethal ischemic episode can induce resistance to a subsequent severe ischemic injury in the brain. This phenomenon is termed ischemic tolerance or ischemic preconditioning, and is an endogenous mechanism that can provide robust neuroprotection. Because of its neuroprotective effects against cerebral ischemia or stroke, ischemic tolerance has been widely studied. However, almost all studies have been performed from the viewpoint of neurons. Accumulating evidence suggests that glial cells have various roles in regulation of brain function, including modulation of synaptic transmission, neuronal excitation, and neuronal structure...

In the follow-up of patients with the clinically isolated syndrome, both clinical and MRI findings should be carefully evaluated by clinicians to avoid misinterpretation and inappropriate diagnosis of multiple sclerosis. We describe a case of a patient with a previous diagnosis of clinically isolated syndrome who developed a new asymptomatic brain lesion at the MRI follow-up. The careful evaluation of clinical history and radiological findings allowed the correct diagnosis of cocaine-associated ischemic stroke...

Yoon Kyung Choi
Carbon monoxide (CO) is a gaseous molecule produced from heme by heme oxygenase (HO). Endogenous CO production occurring at low concentrations is thought to have several useful biological roles. In mammals, especially humans, a proper neurovascular unit comprising endothelial cells, pericytes, astrocytes, microglia, and neurons is essential for the homeostasis and survival of the central nervous system (CNS). In addition, the regeneration of neurovascular systems from neural stem cells and endothelial precursor cells after CNS diseases is responsible for functional repair...

Importance: The androgen receptor inhibitor enzalutamide prolongs survival in men with metastatic castration-resistant prostate cancer (mCRPC). In controlled clinical studies, 0.5% (10 of 2051) of patients experienced seizure, but patients with a history of or risk factors for seizure were excluded. Men with mCRPC and seizure risk factors have an estimated seizure rate of 2.8 per 100 patient-years without enzalutamide exposure. Objective: To assess seizure incidence in patients with seizure risk factors who were receiving enzalutamide for mCRPC...

Sickle cell disease is now a chronic adult illness characterized by progressive multiorgan failure, particularly involving the brain and kidney. The etiology is multifactorial; it includes hemolysis and nitric oxide deficiency. As patients age, most experience neurologic insult. Twenty-five percent of older adults have had a clinical stroke and at least half of the population have had a silent infarct, cortical atrophy, and neurocognitive impairment. Periodic screening with neuroimaging and neurocognitive testing is recommended...

D-4F is an apolipoprotein-A1 mimetic peptide that promotes anti-inflammatory effects. MicroRNA-124 is the most abundant brain-specific microRNA and has anti-inflammatory effects. In this study, we investigated the therapeutic efficacy and mechanisms of D-4F treatment of stroke in type one diabetes mellitus (T1DM) rats. Male Wistar rats were induced with T1DM, subjected to embolic middle cerebral artery occlusion and treated with PBS or D-4F (1 mg/kg i.p.) at 2, 24 and 48 hours after stroke (n=8/group). A battery of function tests, brain blood barrier (BBB) integrity, white matter changes and microRNA expression were evaluated in vivo and in vitro...

Skin-picking disorder (SPD) is a common mental disorder. The predominant symptom involves the repeated scratching and picking of one's own skin. This behavior causes severe tissue damage (sores, scars, and infections), often leading to disfigurement. Besides physical injury, SPD is associated with clinically significant distress and impairment in important areas of functioning. The neurobiological mechanisms of SPD are still poorly understood. In this study, 30 SPD patients and 31 control participants (35 women, 26 men) with a mean age of 34 years were instructed to either scratch or gently stroke a small skin area on their arms during functional magnetic resonance imaging...
