Objective To review the research process of telomerase reverse transcriptase (TERT) in the restoration of neurological diseases. Methods The related l iterature on TERT in the restoration of neurological diseases was extensively reviewed and comprehensively analyzed. Results TERT was the significant component of telomerase and the critical regulator of telomerase activity. It played an important role in the pathomechanism of neurological diseases including tumors,neurodevelopmental deficits, and nerve injury. TERT was becoming a research focus in the reparative therapy of neurological diseases. Conclusion TERT has manifested its great academic significance and appl ication prospects in the reparative therapy of neurological diseases, which deserves a further investigation.
Objective To establish a Chinese clinical controlled trials database of neurology. Methods We identified relevant studies by electronic searching of CBMdisc from 1978 to April 2002, and the Library of Evidence-Based Medicine (Chinese). We also searched manually 11 journals and 4 conference proceedings relevant to neurological diseases. The studies included in this database should be controlled studies relevant to treatment on neurological disease, randomized or only controlled without randomization. Results 3 641 studies were included in this database. Conclusions The Chinese neurological trials database was established. This database will provide Chinese evidence on treatments of various neurological diseases. Studies in this database will also be included in the Cochrane Library to facilitate systematic reviewers.
Objective To analyze the therapeutic effect of olfactory ensheathing cells (OECs) transplantation for central nervous system diseases. Methods Between November 2001 and January 2008, 1 255 participants with central nervous system diseases were enrolled in this cl inical study for fetal OECs transplantation. There were 928 males and 327 femalesaged 1.2-87 (mean 40) years. The course of disease was (4.52 ± 4.67) years. Among them, 656 participants suffered from chronic spinal cord injury (SCI), 457 amyotrophic lateral sclerosis (ALS), 68 cerebral palsy (CP), 20 multiple sclerosis (MS), 11 the sequelae of stoke, 10 ataxia, and 33 residual diseases. The participants came from 71 countries or regions. Accidentally abortional fetal olfactory bulbs were donated voluntarily and were cultured for 2 weeks, then were transplanted. Results One thousand one hundred and twenty-eight cases were followed up for 2-8 weeks (mean 4 weeks) to obtain integrated data. Among them, the neurological functional amel ioration was noticed in 994 participants with the overall short-term improvement rate of 88.12%. Seventy-six patients experienced the various perioperative compl ications with the incidence rate of 6.74%. One hundred and twenty patients with SCI received over 1 year follow-up. And according to ASIA assessment, motor scores increased from (39.82 ± 20.25) to (44.55 ± 18.99) points, l ight touch scores from (51.56 ± 25.89) to (59.81 ± 27.72) points, pain scores from (50.36 ± 27.44) to (57.09 ± 28.51) points for foreign patients (P lt; 0.05); motor scores increased from (40.52 ± 20.80) to (46.45 ± 20.35) points, l ight touch scores from (55.64 ± 26.32) to (68.64 ± 25.89) points, pain scores from (57.05 ± 26.00) to (66.13 ± 24.29) points for good rehabil itation Chinese patients (overall P lt; 0.05); motor scores from (37.03 ± 18.52) to (38.03 ± 18.50 points (P lt;0.05), l ight touch scores from (45.88 ± 22.56) to (46.63 ± 23.09) points (P gt; 0.05), pain scores from (45.25 ± 23.68) to (45.28 ± 23.63) points (P gt; 0.05) for poor rehabil itation Chinese patients. Compared foreign patients and good rehabil itation Chinese patients with poor rehabil itation Chinese patients, difference in score change was remarkable (P lt; 0.05). One hundred and six cases of ALS, 32 CP, 8 MS, 7 ataxia, and 2 stroke sequelae were followed up for 3-48, 3-36, 2-20, 7-17, 6 and 24 months, One hundred and six cases of respectively. Majority of them (113/155, 72.9%）were benefited from OECs transplantation. Conclusion OECs transplantation into brain and spinal cord is feasible and safe . The therapeutic strategy is valuable treatment for such central nervous system diseases such as chronic SCI, ALS, CP and stroke sequelae and can improve the patients’ neurological functions and/or decrease the progressive deterioration.
Glucocorticoids are the first-line therapy of many neurological disorders, with the treatment regimen varying across types and characteristics of neurological disorders. This article reviews the national and international guidelines and expert consensuses in the past decade on glucocorticoids treatment for neurological disorders, and summarizes recommendations from the latest Chinese guidelines and consensuses. In summary, the most frequently used pulse therapy of glucocorticoids in China is intravenous infusion of high-dose (usually 1000 mg/d) methylprednisolone in a short period (often <5 d), followed by gradual tapering, bridging with oral prednisone or direct discontinuation. The treatment regimen for children and juveniles is similar to that for adults but the dose is adjusted by body weight. Pharmacodynamics of glucocorticoids should be considered for the treatment of perinatal women. To provide appropriate glucocorticoids treatment for patients with neurological disorders, clinicians should fully understand features of each neurological disorder and clinical characteristics of individual patient.
Objective To investigate the neuropathogenesis of Adieprime;s pupil. Methods The neuroelectrophysiological and neuroimaging data of 42 patients with Adie's pupil (lightnear dissociation and segmental palsy of iris sphincter) were retrospectively analyzed. There were 37 patients with unilateral pupil dilation and 5 patients with bilateral pupil dilation. Cranial magnetic resonance imaging (MRI, 23 patients), Cranial CT scanning (1 patient), nerve conduction velocity (NCV, 14 patients), limb electromyogram (EMG, 5 patients), both lower extremities EMG (9 patients), visual evoked potential (VEP, 18 patients), somatosensory evoked potential (SEP, 11 patients) and electroencephalograms (EEG,5 patients) were performed on some of those patients. Results Central nervous system midline anatomic variations or minor lesions were found in 13/23 cases of MRI/CT imaging. Slowed sensory NCV and multiple sensorymotor peripheral nerve damages were evident in 6/14 cases of the NCV/EMG assay. 5/18 patients showed prolonged latency of VEP P100. 2/11 cases showed peripheral nerve damage in SEP recording, and 1/5 cases showed abnormal EEG. Conclusion Peripheral nerve damage may be an important pathogenesis of Adie's pupil, while the central nervous system damage is also involved in its pathogenesis.
With the development of ophthalmic optical coherence tomography (OCT) and OCT angiography (OCTA), including the improving of light source, resolution, scanning depth and upgrade of analysis softwares, they can more accurately display the structure of retinal layers and give accurate quantitative measurement. In neuro-ophthalmic diseases, the OCT indicators (the thickness of retinal nerve fiber layer around optic disc and plexus layer in macular gangle cells) and OCTA indicators (the blood flow density of capillaries around optic disc, superficial and deep capillaries in macular area, and the area of foveal avascualr zone) had special changes. It has important value in the differential diagnosis of central nervous system diseases and retinal diseases with visual dysfunction as the first symptom, the diagnosis and differential diagnosis of neuro-ophthalmic disease, the evaluation of progression of neurodegenerative diseases. Neuro-ophthamologists should pay more attention to the exploration and application of OCT and OCTA in the field of neuro-ophthalmology.
Children’s neurological diseases are complex. Common clinical diseases include autism spectrum disorder, cerebral palsy, attention deficit/hyperactivity disorder, etc. The rehabilitation methods in China mainly start with children’s language and cognition. Animal-assisted intervention is a kind of psychosocial intervention, including animal assisted therapy, animal assisted education or animal assisted activities under specific conditions. With its popularity in the world, this field is rapidly approaching a paradigm shift and can be used as a new supplementary and alternative treatment for children’s neurological diseases. By analyzing the literature on animal-assisted intervention and research on children’s neurological diseases, this paper summarizes the application methods and effects of various types of animals in clinical practice, aiming to provide new intervention methods with scientific theoretical basis for the rehabilitation of children with neurological diseases in China and promote the further development of rehabilitation in China.
Idiopathic intracranial hypertension (IIH) is a neurological disease, characterized by increased intracranial pressure and papilledema, and often associated with headache, transient loss of vision and pulsatile tinnitus. IIH typically occurs in women of childbearing age. Over 90.0% of patients are with obesity or over weighted. Loss of sensory visual function is the major morbidity associated with IIH and some patients even develop into blindness. Most patients will have varied degrees of visual impairment, or even a few become blind. Frisén grading system, visual field examination and spectral-domain optical coherence tomography can be used to evaluate and monitor the IIH papilledema functionally and morphologically. In recent years, IIH treatment trials in other countries confirmed that, weight loss and low-salt diet combined with acetazolamide treatment has a clear improvement for IIH patients with mild visual impairment. In-depth understanding of the etiology, clinical manifestations, diagnostic criteria and the main treatment has important clinical significance for IIH patients
Krüppel-like factor 4 (KLF4) is a member of the sample Kruppel transcription factor protein family, is an evolutionary conservative contain zinc finger transcription factors, involved in regulating many cellular processes, such as cell growth, proliferation, differentiation and invasion, KLF4 expression in a variety of tissues and cells in the body, has widely in many physiological and pathological conditions. Many studies have shown that KLF4 is involved in neurobiological processes such as neuroinflammation, oxidative stress, apoptosis and axon regeneration, and is closely related to a variety of nervous system diseases such as epilepsy, stroke, and Alzheimer’s disease. Now KLF4 in its role in the development of nervous system diseases were reviewed, help to understand the pathogenesis of the disease and clinical treatment for diseases of the nervous system to provide potential targets.
Objective To evaluate the relation of human immunodeficiency virus (HIV)-1 ribonucleic acid (RNA) loads in cerebrospinal fluid with central neurological diseases. Methods The inpatients with HIV-1 infection diagnosed by Public Health Clinical Center of Chengdu between January 1st, 2015 and March 1st, 2018 were retrospectively included. The included patients were divided into central neurological disease group and non-central neurological disease group, and high viral load group and low viral load group. The demographic data, CD4+ T lymphocyte count, routine detection of cerebrospinal fluid, HIV RNA load in cerebrospinal fluid and plasma of patients with and without central neurological diseases were observed and compared.Multiple logistic regression analysis was used to identify risk factors for central neurological diseases. Results A total of 367 patients were included. In the central neurological disease group, 210 cases (57.22%) were complicated with central neurological diseases, and cryptococcus infection was the most. Compared with the non-central neurological disease group, the increase rate of cerebrospinal fluid cell counts, cerebrospinal fluid cell counts, cerebrospinal fluid HIV RNA positivity and cerebrospinal fluid HIV RNA load were higher in the central neurological disease group (P<0.05). Logistic regression analysis showed that HIV RNA load in cerebrospinal fluid≥100 000 copies/mL and CD4+ T lymphocyte count<200 cells/mm3 were risk factors for central neurological diseases. Conclusion Cerebrospinal fluid HIV RNA load≥100 000 copies/mL is an independent risk factor for HIV/AIDS patients with central neurological diseases and clinical treatment should take this factor into consideration to reasonably optimize the selection of antiretroviral therapy.
