RESUMO
BACKGROUND: Neuroinflammation is a major driver of age-related brain degeneration and concomitant functional impairment. In patients with Alzheimer's disease, the most common form of age-related dementia, factors that enhance neuroinflammation may exacerbate disease progression, in part by impairing the glymphatic system responsible for clearance of pathogenic beta-amyloid. Inflammatory bowel diseases (IBDs) induce neuroinflammation and exacerbate cognitive impairment in the elderly. The NACHT-LRR and pyrin (PYD) domain-containing protein 3 (NLRP3) inflammasome has been implicated in neuroinflammation. Therefore, we examined if the NLRP3 inflammasome contributes to glymphatic dysfunction and cognitive impairment in an aging mouse model of IBD. METHODS: Sixteen-month-old C57BL/6J and NLRP3 knockout (KO) mice received 1% wt/vol dextran sodium sulfate (DSS) in drinking water to model IBD. Colitis induction was confirmed by histopathology. Exploratory behavior was examined in the open field, associative memory by the novel-object recognition and Morris water maze tests, glymphatic clearance by in vivo two-photon imaging, and neuroinflammation by immunofluorescence and western blotting detection of inflammatory markers. RESULTS: Administration of DSS induced colitis, impaired spatial and recognition memory, activated microglia, and increased A1-like astrocyte numbers. In addition, DSS treatment impaired glymphatic clearance, aggravated amyloid plaque accumulation, and induced neuronal loss in the cortex and hippocampus. These neurodegenerative responses were associated with increased NLRP3 inflammasome expression and accumulation of gut-derived T lymphocytes along meningeal lymphatic vessels. Conversely, NLRP3 depletion protected against cognitive dysfunction, neuroinflammation, and neurological damage induced by DSS. CONCLUSIONS: Colitis can exacerbate age-related neuropathology, while suppression of NLRP3 inflammasome activity may protect against these deleterious effects of colitis.

Although physical exercise is an effective strategy for treatment of ischemic stroke, the underlying protective mechanisms are still not well understood. It has been recently demonstrated that neural progenitor cells play a vital role in the recovery of neurological function (NF) through differentiation into mature neurons. In the current study, we observed that physical exercise significantly reduced the infarct size and improved damaged neural functional recovery after an ischemic stroke. Furthermore, we found that the treatment not only exhibited a significant increase in the number of neural progenitor cells and neurons but also decreased the apoptotic cells in the peri-infarct region, compared to a control in the absence of exercise. Importantly, the insulin-like growth factor-1 (IGF-1)/Akt signaling pathway was dramatically activated in the peri-infarct region of rats after physical exercise training. Therefore, our findings suggest that physical exercise directly influences the NF recovery process by increasing neural progenitor cell count via activation of the IGF-1/Akt signaling pathway.

PURPOSE: This study aimed to explore how well persons with anomic aphasia communicate information during discourse regarding quantity, quality, and efficiency compared to neurotypical controls, to investigate the influence of discourse tasks on informativeness and efficiency and to examine impact factors like aphasia severity and cognitive ability. METHOD: Language samples of four discourse tasks from 31 persons with anomic aphasia and 31 neurotypical controls were collected from Mandarin AphasiaBank. Correct information unit (CIU) analysis measures including the total number of CIUs, percentage of CIUs, CIUs per minute, and words per minute were calculated. Group differences and the effects of discourse tasks on informativeness and efficiency were investigated. Correlations of CIU analysis measures with aphasia severity and cognitive ability were examined. RESULTS: Persons with anomic aphasia showed lower efficiency in conveying information than controls. They underperformed controls on all CIU analysis measures when executing story narrative tasks. Discourse tasks influenced the informativeness and efficiency of both groups. Neurotypical controls delivered the greatest quantity of information most efficiently when narrating stories. Persons with anomic aphasia exhibited reduced quantity of information during procedural discourse and displayed superior information quality in sequential-picture descriptions. Discourse information may be impacted by aphasia severity and cognitive ability, with varying effects depending on the task. CONCLUSIONS: Persons with anomic aphasia are inefficient in communicating discourse messages and perform poorly on all measures in story narratives. When measuring discourse information, the effects of discourse tasks and factors like aphasia severity and cognitive ability should be considered.

PURPOSE: This study was designed to examine the hypothesis that discourse task types influence language performance in Mandarin Chinese-speaking people and to reveal the discourse task-specific linguistic properties of persons with anomic aphasia compared to neurotypical controls. METHOD: Language samples from persons with aphasia (n = 31) and age- and education-matched controls (n = 31) across four discourse tasks (sequential-picture description, single-picture description, story narrative, and procedural discourse) were collected from Mandarin AphasiaBank. Task-specific distributions of parts of speech were analyzed using mosaic plots. The main effects of tasks in each group and the between-group differences within each task for several typical linguistic variables were evaluated, including the mean length of utterance, tokens, moving-average type-token ratio, words per minute, propositional density, noun-verb ratio, noun percentage, and verb percentage. RESULTS: The results revealed an impact of discourse tasks on most language variables in both groups. In the healthy controls, story narratives yielded the highest total words and lowest verb percentage. In the aphasia group, procedural discourse elicited the fewest total words and densest expressions, whereas their single-picture descriptions had the highest noun-verb ratio. For all tasks, the aphasia group performed worse than the control group in the mean length of utterance, tokens, moving-average type-token ratio, and words per minute. For noun-verb ratio, noun percentage, and verb percentage, only one task (i.e., single-picture description) showed significant between-group differences. CONCLUSION: The selection of discourse tasks should be addressed in assessments and interventions for Mandarin Chinese-speaking individuals with aphasia to obtain more accurate and feasible outcomes.

Physical exercise (PE) may be the single most important and accessible lifestyle habit throughout life, it inhibits the neuroinflammatory response and protects the brain against damage. As the innate cells in brain, microglia undergo morphological and functional changes to communicate with neurons protecting the neurons from injury. Herein, aiming at exploring the effects of PE on the communication between microglia-neuron during acute ischemic cerebral infarction, we carried out running wheel training before the conduction of transient middle cerebral artery occlusion (tMCAO) in C57BL/6 J and Cx3cr1-GFP mice. We found that microglial P2Y12 expression in the peri-infarct area was decreased, microglial dynamics and microglia-neuron communications were impaired, using in vivo two-photon imaging. PE up-regulated the microglial P2Y12 expression, increased the microglial dynamics, and promoted the contacts of microglia with neurons. As a result, PE inhibited neuronal Ca2+ overloads and protected against damage of the neuronal mitochondria in acute tMCAO. Mechanistically, PE increased the cannabinoid receptor 2 (CB2R) in microglia, promoted the phosphorylation of Nrf2 (NF-E2-related factor 2) at ser-344, increased the transcription factor level of Mafk, and up-regulated the level of P2Y12, whereby PE increased the levels of CB2R to promote microglia-neuron contacts to monitor and protect neuronal function.
RESUMO
OBJECTIVE: To evaluate the clinical efficacies of botulinum toxin type A (BTX-A) injection under ultrasonic guidance and body surface positioning in poststroke patients with lower extremities spasticity. METHODS: From January 2009 to January 2011, a total of 18 patients with stroke-related spasticity in lower extremities were recruited at Third Affiliated Hospital of Sun Yat-sen University. Under the guide of color Doppler ultrasound and body surface positioning, BTX-A was injected into multi-points of muscles. The outcome after BTX-A injection was assessed by modified Ashworth scale (MAS), passive range of movement (PROM), 10-meter walking test (10 MWT) and Berg balance scale (BBS). Assessments were performed at baseline, Day 3, Weeks 1, 2, 4 and 12 post-injection respectively. RESULTS: Compared the scores of MAS (MAS(pre-treatment) 2.6 ± 0.5, MAS(post-treatment) 1.9 ± 0.2 - 1.1 ± 0.3 score), PROM (PROM(pre-treatment) 7.2 ± 2.4°, PROM(post-treatment) 12.3 ± 2.0 - 18.6 ± 2.2°) between baseline and follow-up at Weeks 1, 2, 4 and 12 post-treatment, there were significant statistical differences (P < 0.05).10 MW (10 MWT(pre-treatment) 55.1 ± 5.2 s, 10 MWT(post-treatment) 48.6 ± 4.2 - 42.9 ± 3.8 s) and BBS (BBS(pre-treatment) 34.7 ± 5.1, BBS(post-treatment) 39.9 ± 4.9 - 45.8 ± 2.1 score) improved greatly at Weeks 2, 4 and 12 post-treatment. CONCLUSION: Ultrasonic guidance and body surface positioning is an accurate positioning modality of using BTX-A for treating the spasticity of lower extremities.

OBJECTIVE: To examine the roles of exercise training in the improvement of damaged neural function and synaptic plasticity. METHODS: An infarction model was induced by left middle cerebral artery occlusion (MCAO). A total of 70 adult Sprague-Dawley rats were randomly divided into 3 groups: physical exercise group (n = 30) undergoing running wheel exercise daily after MCAO, control group (n = 30) and sham-operated group (n = 10). The latter two groups were fed in standard cages without any special training exercise. The rats were scarified at Days 3, 7, 14, 21 and 35 for the evaluation of neural function by neurological severity scores (NSS). And the synaptic ultrastructures at peri-infarction region were examined by specific marker synaptophysin (SYN). RESULTS: Synaptic ultrastructures at peri-infarction region were observed in both the control and exercise training groups. The presynaptic and postsynaptic membranes were relatively intact. And the presynaptic membranes had more synaptic vesicles from Day 7 post-ischemia. The number of SYN positive cells significantly increased in the exercise training group (21 d: 0.8 ± 0.1; 35 d: 0.7 ± 0.1) versus those in the control group (21 d: 0.4 ± 0.1; 35 d: 0.5 ± 0.1) at Days 21 and 35 post-ischemia (P < 0.05). Moreover, the neurological severity scores in the exercise training group (7 d: 7.8 ± 0.8; 14 d: 5.6 ± 0.8; 21 d: 3.3 ± 0.8; 35 d: 3.0 ± 0.8) showed a quicker declination versus those in the control group (7 d: 8.8 ± 0.7; 14 d: 7.7 ± 0.9; 21 d: 6.9 ± 0.8; 35 d: 4.2 ± 0.8) from Day 7 post-ischemia (P < 0.05). CONCLUSION: Exercise training plays an important role in the recovery of damaged neural function and synaptic plasticity after cerebral infarction in rats.

OBJECTIVE: To study the characteristics of genotype spectrum and hematologic parameters in children with HbH disease in the North Guangxi region. METHODS: HbH disease was identified by clinical manifestations, routine blood tests and hemoglobin electrophoresis in 166 children who came form the North Guangxi region. Genotypes were determined by Multi-PCR combined with PCR reverse dot blot. DNA sequencing was used when the genotype could not be identified by regular methods. RESULTS: Of the 166 children with HbH disease, 8 genotypes were identified: --SEA/-α3.7 (82 cases), --SEA/-α4.2 (40 cases), --SEA/αCSα (38 cases), --SEA/αQSα (1 case), --SEA/αWSα (1 case), --SEA/αCD43/44 (-C) α (1 case), --SEA/-α3.7 plus CD17 (AâT) (1 case) and --SEA/-α4.2 plus CD41-42(-TTCT) (1 case). One case was confirmed as the heterozygote of --SEA and an unknown mutation. In the 134 cases with complete medical data, 2 had normal hemoglobin levels, 36 manifested mild anemia, 90 manifested moderate anemia, and 6 (genotype: --SEA/αCSα) showed severe anemia because of the coexistence of infection. Children with the genotype of --SEA/-α3.7 (69 cases), --SEA/-α4.2 (31 cases) and --SEA/αCSα (34 cases) had hemoglobin levels of 62-120, 69-127 and 34-110 g/L respectively. The hemoglobin level in the --SEA/αCSα group was significantly lower than in the deletional HbH disease group (genotypes: --SEA/-α3.7 and --SEA/-α4.2 ) (P<0.05). In contrast, MCV levels in the --SEA/αCSα group were significantly higher than in the deletional HbH disease group (P<0.05). CONCLUSIONS: The genotype spectrum of HbH disease is diverse in the North Guangxi region. Deletional genotype is prevalent. The disease is heterogeneous. The children with --SEA/αCSα HbH disease have severer anemia and higher MCV levels than those with deletional HbH disease.

OBJECTIVE: To investigate the types and frequencies of thalassemia genes carried by the pregnant women in Guilin, Guangxi Zhuang Autonomous Region, China. METHODS: From January 2015 to December 2019, blood samples of the pregnant women who visited the Outpatients of Obstetrics clinic and Eugenics Genetic clinic in Affiliated Hospital of Guilin Medical University were collected. Gap-PCR was used to detect deletional α-thalassemia, PCR-RDB to detect the gene mutations of non-deletional α-thalassemia and ß-thalassemia, and MLPA or DNA sequencing to detect rare thalassemia mutations. Different types and frequencies of thalassemia mutations carried by pregnant women were analyzed statistically. RESULTS: A total of 19 482 blood samples were collected, including 3 801 thalassemia gene carriers (19.51%). Seven types of α-thalassemia gene mutation were detected with a carrier rate of 15.43%. Among them, --SEA deletion (7.32%), -α3.7 deletion (3.97%), and -α4.2 deletion (1.4%) were the commonest types. Twelve types of ß-thalassemia mutations were detected with a carrier rate of 5.02%. Among them, CD41-42 (-TCTT) (2.32%), CD17 (AAG>TAG) (1.23%), and IVS-II-654 (C>T) (0.55%) were the commonest types. In addition, 107 cases of rare thalassemia gene mutations and abnormal hemoglobin were found at the same time. CONCLUSION: Guilin is a high-risk area for thalassemia. Alpha-thalassemia is dominated by --SEA deletion, -α3.7 deletion, and -α4.2 deletion, while ß-thalassemia is by CD41-42 (-TCTT), CD17(AAG>TAG), and IVS-II-654(C>T).

OBJECTIVE: To explore the effects of transcranial direct current stimulation combined with cognitive training on executive function and activities of daily living performance among stroke patients. METHODS: A total of 50 subjects were enrolled and randomly allocated into 2 groups of 25 each. The real-transcranial direct current stimulation group was simultaneously subjected to transcranial direct current stimulation and cognitive training, while the sham-transcranial direct current stimulation group was simultaneously subjected to sham transcranial direct current stimulation and cognitive training. At baseline, and after treatment, each subject was assessed with the Wisconsin Card Sorting Test (WCST), Stroop Color-Word Test (SCWT), Digital Symbol Test (DST), Mini-mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA) and Activities of Daily Living Scale (ADLs). RESULTS: After treatment, the gains in most indices of WCST, SCWT, DST, MMSE, MoCA and ADLs in the real-transcranial direct current stimulation group were significantly higher than those in the sham-transcranial direct current stimulation group (p<0.05). Nonetheless, no significant differences were noted in the gains in SCWT (including only Part A time and error, and Part B time) and activities of daily living (including only basic activities of daily living) between the 2 groups (p>>0.05). CONCLUSION: Transcranial direct current stimulation combined with cognitive training was found to significantly enhance executive function and instrumental activities of daily living performance among stroke patients.

PURPOSE: The present study was to investigate the clinical significance of sphingosine kinase 1 (SPHK1), an oncoenzyme, in the development and progression of gastric cancer. EXPERIMENTAL DESIGN: mRNA and protein levels of SPHK1 expression in normal gastric epithelial cells, gastric cancer cell lines, and paired gastric cancer lesions and the adjacent noncancerous tissues were examined using reverse transcription-PCR and Western blotting. Immunohistochemistry was employed to analyze SPHK1 expression in 175 clinicopathologically characterized gastric cancer cases. Statistical analyses were applied to derive prognostic and diagnostic associations. RESULTS: Levels of SPHK1 mRNA and protein were higher in gastric cancer cell lines than in normal gastric epithelial cells. SPHK1 protein level was up-regulated in gastric cancer lesions compared with that in the paired adjacent noncancerous tissues. Gastric cancer tissues from 115 of 175 (65.7%) patients revealed high level of SPHK1 protein expression in contrast to the undetectable or marginally detectable expression of SPHK1 in the adjacent noncancerous gastric tissues. Significantly different expression levels of SPHK1 were found in patients at different clinical stages (P=0.003), T classification (P=0.035), and M classification (P=0.020). Patients with higher SPHK1 expression had shorter overall survival time, whereas those with lower SPHK1 expression survived longer. Further multivariate analysis suggested that SPHK1 up-regulation was an independent prognostic indicator for the disease. CONCLUSIONS: SPHK1 protein could be a useful marker for the prognosis of gastric cancer. Further study on the potential use of SPHK1 as a therapeutic target is also warranted.

BACKGROUND: Human-derived mesenchymal stromal cells have been shown to improve cognitive function following experimental stroke. The activity of exosomes has been verified to be comparable to the therapeutic effects of mesenchymal stromal cells. However, the effects of exosomes derived from human umbilical cord mesenchymal stem cells (HUC-MSCs) (ExoCtrl) on post-stroke cognitive impairment (PSCI) have rarely been reported. Moreover, whether exosomes derived from C-C chemokine receptor type 2 (CCR2)-overexpressing HUC-MSCs (ExoCCR2) can enhance the therapeutic effects on PSCI and the possible underlying mechanisms have not been studied. AIM: To investigate the effects of ExoCtrl on PSCI and whether ExoCCR2 can enhance therapeutic effects on PSCI. METHODS: Transmission electron microscopy, qNano® particles analyzer, and Western blotting were employed to determine the morphology and CCR2 expression of ExoCtrl or ExoCCR2. ELISA was used to study the binding capacity of exosomes to CC chemokine ligand 2 (CCL2) in vivo. After the intravenous injection of ExoCtrl or ExoCCR2 into experimental rats, the effect of ExoCtrl and ExoCCR2 on PSCI was assessed by Morris water maze. Remyelination and oligodendrogenesis were analyzed by Western blotting and immunofluorescence microscopy. QRT-PCR and immunofluorescence microscopy were conducted to compare the microglia/macrophage polarization. The infiltration and activation of hematogenous macrophages were analyzed by Western blotting and transwell migration analysis. RESULTS: CCR2-overexpressing HUC-MSCs loaded the CCR2 receptor into their exosomes. The morphology and diameter distribution between ExoCtrl and ExoCCR2 showed no significant difference. ExoCCR2 bound significantly to CCL2 but ExoCtrl showed little CCL2 binding. Although both ExoCCR2 and ExoCtrl showed beneficial effects on PSCI, oligodendrogenesis, remyelination, and microglia/macrophage polarization, ExoCCR2 exhibited a significantly superior beneficial effect. We also found that ExoCCR2 could suppress the CCL2-induced macrophage migration and activation in vivo and in vitro, compared with ExoCtrl treated group. CONCLUSION: CCR2 over-expression enhanced the therapeutic effects of exosomes on the experimental PSCI by promoting M2 microglia/macrophage polarization, enhancing oligodendrogenesis and remyelination. These therapeutic effects are likely through suppressing the CCL2-induced hematogenous macrophage migration and activation.
RESUMO
OBJECTIVE: To explore the influence factors of cognitive impairment following first onset of stroke, in order to predict the existence of cognitive impairment in patients with stroke and help for future clinical intervene. METHODS: 364 survivors of first onset of stroke were evaluated by the mini-mental state examination (MMSE) in this study. Data were collected on age, gender, education level, location of brain lesion, diagnostic stroke subtype and so on. Logistic regressions analyzing is used to determine those factors that could predict cognitive impairment of stroke patients by MMSE assessment score. RESULTS: The factors including location of brain lesion, area of the lesion, high homocysteine, side of the lesion, complications, education level and age can join in the logistic regression analysis format. The R of the format is 0.849 and these seven factors can explain 72.1% variation of the scores of MMSE. CONCLUSION: The logistic regression analysis revealed that location of brain lesion, area of the lesion, high homocysteine, side of the lesion, complications, education level and age were predictors of the cognition function assessment of stroke patients. The prevalence of cognitive impairment can be mainly influenced by these factors.

BACKGROUND: Severe jejunoileal atresia is associated with prolonged parenteral nutrition, higher mortality and secondary surgery. However, the ideal surgical management of this condition remains controversial. This study aimed to compare the outcomes of patients with severe jejunoileal atresia treated by three different procedures. METHODS: From January 2007 to December 2016, 105 neonates with severe jejunoileal atresia were retrospectively reviewed. Of these, 42 patients (40.0%) underwent the Bishop-Koop procedure (BK group), 49 (46.7%) underwent primary anastomosis (PA group) and 14 (13.3%) underwent Mikulicz double-barreled ileostomy (DB group). Demographics, treatment and outcomes including mortality, morbidity and nutrition status were reviewed and were compared among the three groups. RESULTS: The total mortality rate was 6.7%, showing no statistical difference among the three groups (P = 0.164). The BK group had the lowest post-operative complication rate (33.3% vs 65.3% for the PA group and 71.4% for the DB group, P = 0.003) and re-operation rate (4.8% vs 38.8% for the PA group and 14.3% for the DB group, P < 0.001). Compared with the BK group, the PA group showed a positive correlation with the complication rate and re-operation rate, with an odds ratio of 4.15 [95% confidence interval (CI): 1.57, 10.96] and 12.78 (95% CI: 2.58, 63.29), respectively. The DB group showed a positive correlation with the complication rate when compared with the BK group, with an odds ratio of 7.73 (95% CI: 1.67, 35.72). The weight-for-age Z-score at stoma closure was -1.22 (95% CI: -1.91, -0.54) in the BK group and -2.84 (95% CI: -4.28, -1.40) in the DB group (P = 0.039). CONCLUSIONS: The Bishop-Koop procedure for severe jejunoileal atresia had a low complication rate and re-operation rate, and the nutrition status at stoma closure was superior to double-barreled enterostomy. The Bishop-Koop procedure seems to be an appropriate choice for severe jejunoileal atresia.
