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.
Central nervous system vascular disease can be combined with a variety of ocular signs, such as orbital pain, flash, visual field defects, vision loss, eye muscle paralysis. Therefore, some patients were first diagnosed in ophthalmology, including aneurysm rupture, arterial dissection, cerebral apoplexy and other critical nervous system diseases that need rapid treatment. If the doctors didn't know enough, the diagnosis and treatment might be delayed. Most of the vascular diseases of the central nervous system related to ophthalmology have clinical manifestations that cannot be explained by ophthalmology. In the face of chronic conjunctivitis, unexplained visual field defect or cranial nerve paralysis with local ineffective treatment, it is necessary to broaden the thinking of differential diagnosis. To understand the characteristics of vascular diseases of the central nervous system that are prone to ocular manifestations can provide references for the clinical diagnosis and treatment of ophthalmology.
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.
This article investigates the role of AMP-activated protein kinase (AMPK) and its downstream signaling targets in mediating cellular processes such as autophagy, apoptosis, and inflammation, offering insights into how acupuncture may treat common central nervous system (CNS) diseases, including ischemic stroke, spinal cord injury, Parkinson disease, and Alzheimer disease. AMPK and its downstream effectors are pivotal in the signaling pathways that underlie the pathophysiology of CNS diseases. These pathways are implicated in a variety of cellular responses that contribute to the progression of neurological disorders. During CNS injury, AMPK can be activated through phosphorylation, triggering the regulation of downstream molecules and exerting protective effects on neuronal function. Acupuncture has been shown to promote neuroprotection and enhance recovery in CNS diseases through multiple mechanisms, one of which involves the activation of AMPK-related signaling pathways. Nevertheless, numerous unresolved challenges remain in this research field.
