Objective: To investigate the clinical features and short-term prognosis of patients with SARS-CoV-2 infection associated acute encephalopathy (AE). Methods: Retrospective cohort study. The clinical data, radiological features and short-term follow-up of 22 cases diagnosed with SARS-CoV-2 infection associated AE in the Department of Neurology, Beijing Children's Hospital from December 2022 to January 2023 were retrospectively analyzed. The patients were divided into cytokine storm group, excitotoxic brain damage group and unclassified encephalopathy group according to the the clinicopathological features and the imaging features. The clinical characteristics of each group were analyzed descriptively. Patients were divided into good prognosis group (≤2 scores) and poor prognosis group (>2 scores) based on the modified Rankin scale (mRS) score of the last follow-up. Fisher exact test or Mann-Whitney U test was used to compare the two groups. Results: A total of 22 cases (12 females, 10 males) were included. The age of onset was 3.3 (1.7, 8.6) years. There were 11 cases (50%) with abnormal medical history, and 4 cases with abnormal family history. All the enrolled patients had fever as the initial clinical symptom, and 21 cases (95%) developed neurological symptoms within 24 hours after fever. The onset of neurological symptoms included convulsions (17 cases) and disturbance of consciousness (5 cases). There were 22 cases of encephalopathy, 20 cases of convulsions, 14 cases of speech disorders, 8 cases of involuntary movements and 3 cases of ataxia during the course of the disease. Clinical classification included 3 cases in the cytokine storm group, all with acute necrotizing encephalopathy (ANE); 9 cases in the excitotoxicity group, 8 cases with acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) and 1 case with hemiconvulsion-hemiplegia syndrome; and 10 cases of unclassified encephalopathy. Laboratory studies revealed elevated glutathione transaminase in 9 cases, elevated glutamic alanine transaminase in 4 cases, elevated blood glucose in 3 cases, and elevated D-dimer in 3 cases. Serum ferritin was elevated in 3 of 5 cases, serum and cerebrospinal fluid (CSF) neurofilament light chain protein was elevated in 5 of 9 cases, serum cytokines were elevated in 7 of 18 cases, and CSF cytokines were elevated in 7 of 8 cases. Cranial imaging abnormalities were noted in 18 cases, including bilateral symmetric lesions in 3 ANE cases and "bright tree appearance" in 8 AESD cases. All 22 cases received symptomatic treatment and immunotherapy (intravenous immunoglobulin or glucocorticosteroids), and 1 ANE patient received tocilizumab. The follow-up time was 50 (43, 53) d, and 10 patients had a good prognosis and 12 patients had a poor prognosis. No statistically significant differences were found between the two groups in terms of epidemiology, clinical manifestations, biochemical indices, and duration of illness to initiate immunotherapy (all P>0.05). Conclusions: SARS-CoV-2 infection is also a major cause of AE. AESD and ANE are the common AE syndromes. Therefore, it is crucial to identify AE patients with fever, convulsions, and impaired consciousness, and apply aggressive therapy as early as possible.

OBJECTIVE@#To observe the effects of moxibustion at "Baihui" (GV 20) and "Dazhui" (GV 14) at different time points on the serum level of β-endorphin (β-EP), substance P (SP) and expression of interleukin-1β (IL-1β) and cyclooxygenase-2 (COX-2) protein in brainstem in rats with migraine, and to explore the effect and mechanism of moxibustion in preventing and treating migraine.@*METHODS@#Forty male SD rats were randomly divided into a blank group, a model group, a prevention+treatment (PT) group and a treatment group, 10 rats in each group. Except the blank group, the rats in the remaining groups were injected with nitroglycerin subcutaneously to prepare migraine model. The rats in the PT group were treated with moxibustion 7 days before modeling (once a day) and 30 min after modeling, while the rats in the treatment group were treated with moxibustion 30 min after modeling. The "Baihui" (GV 20) and "Dazhui" (GV 14) were taken for 30 minutes each time. The behavioral scores in each group were observed before and after modeling. After intervention, ELISA method was used to detect the serum level of β-EP and SP; the immunohistochemistry method was used to detect the number of positive cells of IL-1β in brainstem; the Western blot method was used to detect the expression of COX-2 protein in brainstem.@*RESULTS@#Compared with the blank group, the behavioral scores in the model group were increased 0-30 min, 60-90 min and 90-120 min after modeling (P<0.01); compared with the model group, in the treatment group and the PT group, the behavioral scores were decreased 60-90 min and 90-120 min after modeling (P<0.01). Compared with the blank group, in the model group, the serum level of β-EP was decreased (P<0.01), while the serum level of SP, the number of positive cells of IL-1β in brainstem and the expression of COX-2 protein were increased (P<0.01). Compared with the model group, in the PT group and and the treatment group, the serum level of β-EP was increased (P<0.01), while the serum level of SP, the number of positive cells of IL-1β and the expression of COX-2 protein in brainstem were decreased (P<0.01, P<0.05). Compared with the treatment group, in the PT group, the serum level of β-EP was increased and COX-2 protein expression was decreased (P<0.05).@*CONCLUSION@#Moxibustion could effectively relieve migraine. The mechanism may be related to reduce the serum level of SP, IL-1β and COX-2 protein expression in brainstem, and increase the serum level of β-EP, and the optimal effect is observed in the PT group.

OBJECTIVE@#To observe the effects of acupuncture on swallowing function and quality of life for patients with dysphagia in Parkinson's disease (PD).@*METHODS@#A total of 60 patients of PD with dysphagia were randomly divided into an observation group (30 cases, 2 cases dropped off) and a control group (30 cases, 3 cases dropped off). The control group was given conventional medication therapy and rehabilitation training. On the basis of the treatment as the control group, the observation group was given acupuncture at Fengfu (GV 16), Baihui (GV 20), Shenting (GV 24), Yintang (GV 24+), Yansanzhen and bilateral Fengchi (GB 20), 30 min each time, once a day, 6 times a week for 4 weeks. Before and after treatment, the Kubota water swallowing test, standardized swallowing assessment (SSA) and swallowing quality of life (SWAL-QOL) were used to evaluate the swallowing function and quality of life of the two groups.@*RESULTS@#After treatment, the Kubota water swallowing test grade, SSA scores in the two groups were decreased compared with those before treatment (P<0.05, P<0.001),the SWAL-QOL scores were increased compared with those before treatment (P<0.001); in the observation group,the Kubota water swallowing test grade and SSA score were lower than those in the control group (P<0.05),the SWAL-QOL score was higher than that in the control group (P<0.001).@*CONCLUSION@#On the basis of conventional medication therapy and rehabilitation training,acupuncture could improve the swallowing function and quality of life for patients of PD with dysphagia.

<p><b>BACKGROUND</b>Very few researchers have studied the changes in peripheral lymphocyte patterns in adult tuberculosis (TB) and even less researches have been conducted in pediatric TB. In this study, we obtained blood samples from 114 Chinese pediatric TB patients and 116 matched controls to study the association of phenotypic subsets of peripheral lymphocytes with different clinical phenotypes of TB.</p><p><b>METHODS</b>The subjects were classified as the control group and the TB patients group which were further divided into a pulmonary TB group and an extra-pulmonary TB group (more serious than the former). The distribution of lymphocyte subpopulations, including T lymphocytes, CD4(+) T lymphocytes, CD8(+) T lymphocytes, B lymphocytes, and natural killer (NK) cells, were quantitatively analyzed by flow cytometry.</p><p><b>RESULTS</b>Compared to the healthy controls, TB infection was associated with significantly higher B cell (P < 0.0001), and lower T cell (P = 0.029) and NK cell (P < 0.0001) percentages. Compared to pulmonary TB patients, extra-pulmonary TB was associated with relatively higher B cell (P = 0.073), and lower T cell percentages (P = 0.021), higher purified protein derivative (PPD) negative rate (P = 0.061), and poorer PPD response (P = 0.010). Most pulmonary TB cases were primary pulmonary TB (89.1%), and most extra-pulmonary TB cases had TB meningitis (72.1%).</p><p><b>CONCLUSIONS</b>This study demonstrates changes in the lymhocyte distribution in children suffering from different clinical phenotypes of TB; such as primary pulmonary TB, and TB meningitis. These patterns may have significance in understanding the pathogenesis and prognostic markers of the disease, and for developing immunomodulatory modalities of therapy.</p>
