ABSTRACT
Introduction: Anti-sulfatide antibodies are key biomarkers for the diagnosis of Guillain-Barré syndrome (GBS). However, case reports on anti-sulfatide antibody-related GBS are rare, particularly for atypical cases. Case description case 1: A 63 years-old man presented with limb numbness and diplopia persisting for 2 weeks, with marked deterioration over the previous 4 days. His medical history included cerebral infarction, diabetes, and coronary atherosclerotic cardiomyopathy. Physical examination revealed limited movement in his left eye and diminished sensation in his extremities. Initial treatments included antiplatelet agents, cholesterol-lowering drugs, hypoglycemic agents, and medications to improve cerebral circulation. Despite this, his condition worsened, resulting in bilateral facial paralysis, delirium, ataxia, and decreased lower limb muscle strength. Treatment with intravenous high-dose immunoglobulin and dexamethasone resulted in gradual improvement. A 1 month follow-up revealed significant neurological sequelae. Case description case 2: A 53 years-old woman was admitted for adenomyosis and subsequently experienced sudden limb weakness, numbness, and pain that progressively worsened, presenting with diminished sensation and muscle strength in all limbs. High-dose intravenous immunoglobulin, vitamin B1, and mecobalamin were administered. At the 1 month follow-up, the patient still experienced limb numbness and difficulty walking. In both patients, albuminocytologic dissociation was found on cerebrospinal fluid (CSF) analysis, positive anti-sulfatide antibodies were detected in the CSF, and electromyography indicated peripheral nerve damage. Conclusion: Anti-sulfatide antibody-related GBS can present with Miller-Fisher syndrome, brainstem encephalitis, or a combination of the two, along with severe pyramidal tract damage and residual neurological sequelae, thereby expanding the clinical profile of this GBS subtype. Anti-sulfatide antibodies are a crucial diagnostic biomarker. Further exploration of the pathophysiological mechanisms is necessary for precise treatment and improved prognosis.
ABSTRACT
OBJECTIVE: To investigate the short-term and long-term clinical effects of otopoint pellet-pressing combined with medication in the treatment of patients with migraine without aura and its impact on plasma 5-hydroxytryptamine(5-HT) and calcitonin gene-related peptide(CGRP) contents. METHODS: Patients with migraine without aura were randomly divided into medication(control) group(n=48) and otopoint pellet-pressing plus medication (treatment) group(n=49). Patients of the control group were given oral Flunarizine capsules(10 mg/time) twice a day, and those of the treatment group received same dosage of Flunarizine and pellet-pressing of otopoints Nao(Brain), Nie (Temporal), Shenmen(Shenmen), Jiaogan(Sympathy) and Pizhixia(Subcortex), 2 min/point, 3 times a day, simultaneously. The treatment was conducted for 1 month. The short-term and long-term clinical effects were evaluated according to Yang and colleagues' methods, and "Guiding principles for clinical research of new TCM drugs (trial)". The contents of plasma 5-HT and CGRP were detected by ELISA. RESULTS: After one month's treatment, of the 48 and 49 patients in the control and treatment groups, 10(20.83%)and 17(34.69%) were under control, 19(39.59%)and 23(46.94%) experienced marked improvement, 10(20.83%)and 7(14.29%)were effective, 9(18.75%) and 2(4.08%) failed, with the total effective rates being 81.25% and 95.92%, respectively. Six months' follow-up survey showed that of the 48 and 49 patients in the control and treatment groups, 4(8.33%)and 11(22.45%) were under control, 20(41.67%)and 24(48.98%)experienced marked improvement, 11(22.92%)and 9(18.37%)were effective, and 13(27.08%) and 5(10.20%)failed, with the total effective rates being 72.92% and 89.80%, respectively. The number of headache attacks, duration of each attack and the degree of headache were significantly decreased after 1 and 6 months' treatment in both groups in comparison with their own pre-treatment (P<0.05). The contents of plasma 5-HT at the time-points of 1 and 6 months were markedly increased (P<0.05), and those of plasma CGRP at the two time points markedly decreased in both groups in comparison with their own pre-treatment (P<0.05). The therapeutic effects of the treatment group were obviously superior to those of the control group in lowering the number of headache attacks, duration of each attack and the degree of headache and plasma CGRP content, as well as in increasing plasma 5-HT levels after 1 and 6 months' treatment (P<0.05). CONCLUSION: Otopoint pellet-pressing combined with oral administration of Flunarizine can significantly improve the clinical symptoms in patients with migraine without aura, and possess a stable long-term clinical effect, which may be associated with its effect in increasing plasma 5-HT and decreasing CGRP levels.

Parkinson's disease (PD), the second most common neurodegenerative disease, is characterized by the progressive loss of dopaminergic neurons in the substantia nigra. Although the molecular mechanisms underlying dopaminergic neuronal degeneration in PD remain unclear, neuroinflammation is considered as the vital mediator in the pathogenesis and progression of PD. Bushen-Yizhi Formula (BSYZ), a traditional Chinese medicine, has been demonstrated to exert antineuroinflammation in our previous studies. However, it remains unclear whether BSYZ is effective for PD. Here, we sought to assess the neuroprotective effects and explore the underlying mechanisms of BSYZ in a 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine- (MPTP-) induced mouse model of PD. Our results indicate that BSYZ significantly alleviates the motor impairments and dopaminergic neuron degeneration of MPTP-treated mice. Furthermore, BSYZ remarkably attenuates microglia activation, inhibits NLPR3 activation, and decreases the levels of inflammatory cytokines in MPTP-induced mouse brain. Also, BSYZ inhibits NLRP3 activation and interleukin-1ß production of the 1-methyl-4-phenyl-pyridinium (MPP+) stimulated BV-2 microglia cells. Taken together, our results indicate that BSYZ alleviates MPTP-induced neuroinflammation probably via inhibiting NLRP3 inflammasome activation in microglia. Collectively, BSYZ may be a potential therapeutic agent for PD and the related neurodegeneration diseases.
