RESUMO
BACKGROUND: The condition and correlation of fatigue, sleep and physical activity in postoperative patients with pituitary adenomas remain unclear. This survey aimed to evaluate the current status and influencing factors of fatigue, sleep and physical activity in postoperative patients with pituitary adenomas. METHODS: Patients undergoing pituitary adenoma resection in two tertiary hospitals from November 2019 to November 2021 were included. The general data questionnaire, Multidimensional Fatigue Inventory (MFI-20), Pittsburgh Sleep Quality Index (PSQI) and international physical activity questionnaire were used for data analysis. RESULTS: In total, 184 patients with pituitary adenomas were included. The postoperative patients with pituitary adenomas had a high level of fatigue. In total, 34 (18.5%) patients had low level of physical activity, 76(41.3%) patients had medium level of physical activity and 74 (40.2%) had high level of physical activity. Postoperative time, PSQI, physical activity level and gender were the influencing factors of fatigue in patients with pituitary adenomas (all P < 0.05). CONCLUSIONS: Postoperative patients with pituitary adenomas have a higher level of fatigue, and it is related to reduced sleep quality and activity. Relevant nursing measures should be taken according to the influencing factors of fatigue to reduce the fatigue of postoperative patients with pituitary adenomas.

BACKGROUND: Dysphagia is a common condition after stroke, and it is associated with many complications. Early and effective treatments are essential to the prognosis of patients with dysphagia. We aimed to evaluate the effects and safety of capsaicin combined with ice stimulation in patients with dysphagia after stroke. METHODS: Patients with dysphagia admitted to our hospital from December 2017 to December 2019 were included. The control group received the ice stimulation, and the experimental group received the combined capsaicin and ice stimulation. The grade of water swallowing test (WST), standard swallowing assessment (SSA) scores and the serum substance P level was compared between control (ice only) and experimental group (capsaicin plus ice). RESULTS: No differences before treatment and significance following treatment in each group (before and after) and between groups (capsaicin plus ice vs ice only) were found (all P > .05); the SSA scores were significantly reduced after intervention for both groups (all P < .001), and after intervention, SSA score in experimental group was significantly less than that of control group (P < .001). After intervention, the number of patients graded as WST level I-II in experimental group was significantly more than that of control group (P < .001); the serum substance P level was significantly increased after intervention for both groups (all P < .05), and after intervention, the serum substance P level in experimental group was significantly higher than that of control group (P = .007). CONCLUSIONS: The combined use of capsaicin with ice stimulation is beneficial to the recovery of swallowing function of patients with dysphagia, which should be included into the clinical practice.

BACKGROUND/AIMS: Dysphagia is a common complication after acute stroke. While there are several innovative treatments being tested to improve the swallowing function of stroke patients with dysphagia, our aim is to explore the use of readily available natural capsaicin in stroke patients with dysphagia. STUDY DESIGN: A randomized, double-blind study. METHODS: Sixty-nine hospitalized stroke patients were enrolled in this study. The capsaicin intervention group received thermal tactile stimulation with supplementation of natural capsaicin and additional nectar viscosity boluses. The control group received stimulation and boluses with placebo. Swallowing function was evaluated before and after the 3-week treatment, using Volume-Viscosity Swallow Test, Eating Assessment Tool, Standardized Swallowing Assessment, and Water Swallow Test. RESULTS: The score decreases in the Eating Assessment Tool and Standardized Swallowing Assessment of the capsaicin intervention group were significantly greater than that of the placebo control group (P < .01). Among the 60 patients, the capsaicin intervention group exhibited effectiveness in a higher number of patients (nâ¯=â¯27, 90%) than the placebo group (nâ¯=â¯9, 30%, P < .001). CONCLUSIONS: Regular use of natural capsaicin could promote the recovery of swallow function in stroke patients with dysphagia. The ample availability of natural capsaicin could provide a low cost, easily accessible, and safe alternative method to address dysphagia in stoke patients.

PURPOSE: Tracheostomy usually accompanied by the impairment of cough reflex, which may affect the clearance of secretions and result in the occurrence and development of pulmonary inflammation. Previous research has demonstrated that citric acid could effectively evoke cough. However, there are limited data available on this topic specific to the cough stimulation method, and the roles of citric acid in tracheostomy still remain obscure. The aims of present study were to identify the potential roles of citric acid in conjunction with saline nebulization in tracheostomy in guinea pigs. MATERIALS AND METHODS: Experimental tracheostomy model was induced in guinea pigs, and different nebulization interventions were implemented. The expression of P-selectin and platelet count were analyzed by flow cytometer and automatic globulimeter, the histological changes in trachea and lung tissue were assessed by hematoxylin and eosin staining, and the inflammatory cytokines and substance P (SP) levels in bronchoalveolar lavage fluid were evaluated by enzyme-linked immunosorbent assay. RESULTS: Tracheostomy resulted in the disorder of trachea mucosa and cilia, the inflammatory cell infiltration in lung tissue, the increase of IL-6, TNF-α levels and the decrease of SP level. Citric acid alone increase the SP level, and the joint action of citric acid and saline nebulization further showed significantly beneficial effects on pathological, inflammatory changes and SP level. CONCLUSIONS: Citric acid combined with saline nebulization contributes to the alleviation of tracheotomy-induced tracheal damage and pulmonary inflammation in an experimental tracheostomy model in guinea pigs. This may provide novel insights into the inflammation management and cough recovery after tracheostomy.

This study aimed to study the role of P2X7 in intracerebral hemorrhage (ICH)-induced secondary brain injury (SBI) and the underlying mechanisms. An autologous blood injection was used to induce ICH model in Sprague-Dawley rats, and cultured primary rat cortical neurons were exposed to oxyhemoglobin to mimic ICH in vitro. siRNA interference and over-expression of P2X7, agonists and antagonists of P2X7, p38 MAPK and ERK were exploited. The protein levels were assessed using Western blotting and immunofluorescence staining. Terminal deoxynucleotidyl transferase dUTP nick end labeling staining and Fluoro-Jade B were conducted to detect apoptotic and degenerating neurons. The protein levels of P2X7, phosphorylated p38, ERK, active caspase-3 and NF-κB were significantly increased by ICH, which could be further increased by BzATP (P2X7 agonist) and reduced by BBG (P2X7 antagonist). And BzATP demonstrated a significant increase in cell death ratio and brain water content, while BBG led to a reverse results. In addition, Over- P2X7 increased the levels of P2X7, phosphorylated p38, ERK, active caspase-3 and NF-κB, and aggravated cell apoptosis, while si P2X7 resulted in opposite effects. Finally, the protein levels of phosphorylated P38 and active caspase 3 were decreased by BzATP plus Hydrochloride (p38 MAPK antagonist) and increased vy BBG plus Asiatic acid (p38 MAPK agonist), while the protein levels of phosphorylated ERK and NF-κB were decreased with BzATP plus Nimbolide (ERK antagonist) and increased with BBG plus Saikosaponin C (ERK agonist). This study demonstrates that inhibition of P2X7 could prevent ICH-induced SBI via MAPKs signaling pathway.

After traumatic brain injury (TBI), patients usually live with significant disability and socioeconomic burdens. Acute exposure to alcohol is considered a major risk factor for TBI. Numerous studies have examined whether alcohol exposure is related to the risk of mortality in patients with TBI, yet the results remain inconsistent. We performed a meta-analysis to assess whether acute alcohol exposure affects the mortality rate of TBI patients. We searched PubMed, EMBASE, and the Cochrane Library up to November 2015 for relevant studies. We screened studies based on their inclusion criteria and selected the studies that reported mortality rate, which included 18 observational studies. We used R to analyze the included data. An initial result showed that the presence of a positive blood alcohol concentration (BAC) had no significant relation with mortality rate (OR = 0.92, 95% CI = 0.83 to 1.01), but there was notable heterogeneity along with variable results according to sensitivity analysis. For the BAC-positive population, low BAC (1 to 100 mg/dl) carried a higher risk of mortality than moderate BAC (100 to 230 mg/dl) (OR = 1.40, 95% CI = 1.09 to 1.81), moderate and high BAC as a single category (>100 mg/dl) (OR = 1.57, 95% CI = 1.28 to 1.94), or high BAC (>230 mg/dl) (OR = 1.76, 95% CI = 1.34 to 2.30). However, moderate BAC did not increase the mortality risk when compared with high BAC (OR = 1.20, 95% CI = 0.89 to 1.63). Whether positive BAC at the time of admission after TBI reduces mortality rate compared with the rate under negative BAC remains unknown. In addition, low BAC (1 to 100 mg/dl) poses a risk of mortality compared with higher BAC. Further studies assessing the effect of alcohol between the BAC-positive group and the BAC-negative group are still needed.

BACKGROUND: Gum chewing has been reported to enhance the intestinal function recovery after caesarean section, current perspectives and practice guidelines vary widely on the use of gum chewing, more studies on the role of gum chewing after caesarean section are needed. METHODS: We performed a comprehensive, systematic meta-analysis of randomized controlled trials (RCTs) on the efficacy of gum chewing after caesarean section. Studies were identified by searching EMBASE et al database (until June 30, 2016). Summary odd ratios or weighted mean differences with 95% confidence intervals were calculated for each outcome with fixed- or random-effects model. RESULTS: Ten RCTs with a total of 1659 women were included in our meta-analysis. Gum chewing provided significant benefits in reducing the time to first passage of flatus, first defecation, first bowel sound, first bowel movement and the length of hospital stay, but not in the time to first feeling of hunger. CONCLUSIONS: Gun chewing hastens the intestinal function recovery after caesarean section and offers a safe and inexpensive option. High-quality and larger-scale RCTs are still warranted to clarify the role of gum chewing in intestinal function recovery after caesarean section.

Massive studies have focused on the understanding of the pathobiology of cellular and molecular changes and injury mechanisms after traumatic brain injury (TBI), but very few studies have specially discussed the role of synapses in the context of TBI. This paper specifically highlights the role and therapeutic potentials of synapses after TBI. First, we review and conclude how synapses interact with constant structural, metabolic, neuroendocrine, and inflammatory mechanisms after TBI. Second, we briefly describe several key synaptic proteins involved in neuroplasticity, which may be novel neuronal targets for specific intervention. Third, we address therapeutic interventions in association with synapses after TBI. Finally, we concisely discuss the study gaps in the synapses after TBI, in hopes that this would provide more insights for future studies. Synapses play an important role in TBI; while the understandings on the synaptic participation in the treatments and prognosis of TBI are lacking, more studies in this area are warranted.

AIMS: To determine the effects of low-flow oxygen therapy with humidified or non-humidified oxygen in adult patients. BACKGROUND: Although non-humidified oxygen in low-flow oxygen therapy is recommended by many guidelines, humidifying oxygen regardless of oxygen flow has been routinely performed in China and Japan and further studies are needed to evaluate the evidence. DESIGN: A systematic review and meta-analysis that comply with the recommendations of the Cochrane Collaboration were conducted. DATA SOURCES: Studies (1980-2016) were identified by searching PUBMED, EMBASE, Science Direct, Cochrane library, CNKI and Wanfang Database. METHODS: We performed a comprehensive, systematic meta-analysis of randomized controlled trials on the efficacy of humidified and non-humidified low-flow oxygen therapy. Summary risk ratios or weighted mean differences with 95% confidence intervals were calculated using a fixed- or random-effects model. RESULTS: Twenty-seven randomized controlled trials with a total number of 8,876 patients were included. Non-humidified oxygen offers more benefits in reducing the bacterial contamination of humidifier bottles, as shown by the mean operating time for oxygen administration and the respiratory infections compared with humidified oxygen therapy. No significant differences were found in dry nose, dry nose and throat, nosebleed, chest discomfort, the smell of oxygen and SpO2 changes. CONCLUSIONS: The routine humidification of oxygen in low-flow oxygen therapy is not justifiable and non-humidified oxygen tends to be more beneficial. However, considering that the quality of most included studies is poor, rigorously designed, large-scale randomized controlled trials are still needed to identify the role of non-humidified oxygen therapy.

AIMS AND OBJECTIVES: To describe the incidence of prolonged fever in patients admitted to the neurosurgery department, and the corresponding risk indicators. BACKGROUND: Prolonged fever was defined as a temperature higher than 38·3°C lasting more than five days. Prolonged fever is a common phenomenon and could lead to worsened outcomes in specific patient groups, especially for those with brain injury. However, the studies on prolonged fever in neurosurgical patients are limited and insufficient. DESIGN: A retrospective observational study. METHODS: Retrospective data were collected from 1 January 2014 to 31 December 2014, at the neurosurgical department of a large teaching hospital. We performed univariate and multivariate analyses to identify independent indicators for prolonged fever vs. short-term fever. RESULTS: Among 2845 patients, prolonged fever occurred in 466 (16%). The older patients were associated with longer duration of mechanical ventilation and hospital stay. It predominantly occurred in patients with subarachnoid haemorrhage (SAH) and traumatic brain injury. Patients receiving antibiotic treatment tended to manifest prolonged fever more frequently. Multivariate analysis revealed that the use of antibiotics, central venous catheter and prolonged mechanical ventilation were independent risk predictors for prolonged fever. Patients diagnosed with brain tumour seemed to be not associated with prolonged fever. CONCLUSIONS: Prolonged fever is the common complication in neurosurgical patients. The risks of prolonged fever in patients are attributed to antibiotic therapy, use of central venous catheter and prolonged mechanical ventilation. Indicators of prolonged fever are helpful for better identification of high-risk patients and fever control. RELEVANCE TO CLINICAL PRACTICE: A better reveal on the epidemiology and predictable factors of prolonged fever in neurosurgical patients will provide a better understanding on those patients who are most at risk, and therefore contribute to fever control and better outcome.

AIMS: Describe physician-nurse collaboration in feeding critically ill patients and explore the influence factors related to this collaboration, which can provide information for clinical practice and future studies. BACKGROUND: Appropriate nutrition support is essential and significant for critically ill patients, and the importance of physician-nurse collaboration in other fields has been confirmed, yet there are limited studies put insights into the status of physician-nurse collaboration in feeding critically ill patients. METHODS: A cross-sectional survey with a covering of 15 hospitals was conducted. A 21-item questionnaire was administered to physicians and nurses in critical care units. Descriptive statistics, univariate and multiple stepwise regression analysis were performed to evaluate the physician-nurse collaboration in feeding critically ill patients. RESULTS: A total of 331 respondents completed the questionnaire. Nurses and physicians were found to have differing perceptions of the physician-nurse collaboration in feeding critically ill patients, with nurses reporting lower levels of collaboration. Nurses consistently gave more negative responses on every survey question compared with physicians. Age, education and clinical experience significantly influenced the nurses' perceptions of cooperation, and age, education, ICU type, and seniority affected the physicians' perceptions of collaboration. CONCLUSIONS: Physicians, nurses and hospital administrators should highlight the physician-nurse collaboration in feeding critically ill patients and reinforce the cooperation based on potential influencing factors. Further research is required to establish feasible cooperative protocol and evaluate the effectiveness of the approach.

PURPOSE: The purpose of this study was to describe the biological changes after incontinence-associated dermatitis (IAD) induction by pancreatin in the guinea pigs and to explore the potentially appropriate timing and pancreatin concentration for IAD induction with different severity. DESIGN: In vivo, experimental study. SUBJECTS AND SETTING: An experimental animal model (guinea pig) in a controlled laboratory setting was used for investigation. METHODS: We developed an IAD model in guinea pigs by occluded application of 1%, 5%, and 10% pancreatin solutions for 1, 3, and 5 days, respectively. The irritant was applied to the posterior aspect of shaved guinea pigs. We used an adapted visual scoring system to evaluate IAD and its severity. We also measured differences of the fluid absorption rate as a proxy for transepidermal water loss and enzyme-linked immunosorbent assays of interleukin 2 and interferon-γ expression as indicators of IAD-related inflammation. Analysis of variance (ANOVA) was used to examine group differences. RESULTS: Higher pancreatin concentrations led to more severe skin responses and higher mean visual scale scores, yet the statistically score differences were only observed in the 1% and 5% pancreatin groups after 3 and 5 days of exposure compared with 1 day of exposure (P < .05). The average absorbed fluid rate increased from 1 to 3 days of exposure and reached a plateau at 3 days; significant differences were observed in 3 and 5 days of exposure (P < .05) when compared with 1 day of exposure but not between 3 and 5 days of exposure. CONCLUSIONS: Exposure of a guinea pig animal model to 1%, 5%, and 10% pancreatin solutions over a 3-day period induced IAD with different levels of severity. Additional studies using this model are warranted.

BACKGROUND: Saline fluid nebulization is highly recommend to combat the complications following tracheostomy, yet the understandings on the role of osmolality in saline solution for nebulization remain unclear. OBJECTIVES: To investigate the biological changes in the early stage after tracheostomy, to verify the efficacy of saline fluid nebulization and explore the potential role of osmolality of saline nebulization after tracheostomy. METHODS: Sprague-Dawley rats undergone tracheostomy were taken for study model, the sputum viscosity was detected by rotational viscometer, the expressions of TNF-α, AQP4 in bronchoalveolar lavage fluid were assessed by western blot analysis, and the histological changes in endothelium were evaluated by HE staining and scanning electron microscopy (SEM). RESULTS: Study results revealed that tracheostomy gave rise to the increase of sputum viscosity, TNF-α and AQP4 expression, mucosa and cilia damage, yet the saline fluid nebulization could significantly decrease the changes of those indicators, besides, the hypertonic, isotonic and hypertonic saline nebulization produced different efficacy. CONCLUSIONS: Osmolality plays an important role in the saline fluid nebulization after tracheostomy, and 3% saline fluid nebulization seems to be more beneficial, further studies on the role of osmolality in saline fluid nebulization are warranted.

BACKGROUND: The elimination of schistosomiasis remains a challenging task, with current measures primarily focused on the monitoring and control of Oncomelania hupensis (O. hupensis) snail, the sole intermediate host of Schistosome japonicum. Given the emerging, re-emerging, and persistent habitats of snails, understanding their genetic diversity might be essential for their successful monitoring and control. The aims of this study were to analyze the genetic diversity of Oncomelania hupensis robertsoni (O. h. robertsoni) using microsatellite DNA markers; and validate the applicability of previously identified microsatellite loci for O. hupensis in hilly regions. METHODS: A total of 17 populations of O. h. robertsoni from Yunnan Province in China were selected for analysis of genetic diversity using six microsatellite DNA polymorphic loci (P82, P84, T4-22, T5-11, T5-13, and T6-27). RESULTS: The number of alleles among populations ranged from 0 to 19, with an average of 5. The average ranges of expected (He) and observed (Ho) heterozygosity within populations were 0.506 to 0.761 and 0.443 to 0.792, respectively. The average fixation index within the population ranged from - 0.801 to 0.211. The average polymorphic information content (PIC) within the population ranged from 0.411 to 0.757, appearing to be polymorphic for all loci (all PIC > 0.5), except for P28 and P48. A total of 68 loci showed significant deviations from Hardy-Weinberg equilibrium (P < 0.05), and pairwise Fst values ranged from 0.051 to 0.379. The analysis of molecular variance indicated that 88% of the variation occurred within snail populations, whereas 12% occurred among snail populations. Phylogenetic trees and principal coordinate analysis revealed two distinct clusters within the snail population, corresponding to "Yunnan North" and "Yunnan South". CONCLUSIONS: O. h. robertsoni exhibited a relatively high level of genetic differentiation, with variation chiefly existing within snail populations. All snail in this region could be separated into two clusters. The microsatellite loci P82 and P84 might not be suitable for classification studies of O. hupensis in hilly regions. These findings provided important information for the monitoring and control of snail, and for further genetic diversity studies on snail populations.

BACKGROUND: Nutrition supports is essential to the prognosis of stroke patients with dysphagia. It's necessary to evaluate the effects and safety of intermittent tube feeding for stroke patients with dysphagia, to provide evidence for the management of dysphagia. METHODS: Cochrane Library et al. databases were searched for randomized controlled trials (RCTs) on the intermittent tube feeding for stroke patients with dysphagia up to Feb 15, 2021. Bias risk assessment tool recommended by Cochrane was used for quality assessment, and Revman5.3 software was used for data analysis. RESULTS: A total of 11 RCTs involving 762 stroke patients with dysphagia were included. Meta-analysis indicated that intermittent tube feeding could significantly increase the rate of dysphagia function improvement [odd ratio (ORâ) =â5.22, 95% confidence interval (CI): 3.38-8.07], serum albumin level [mean difference (MD) =â3.07, 95% CI: 1.65-4.49], hemoglobin level (MD =1.55, 95% CI: 1.19-1.95), prealbumin level (MD =1.79, 95% CI: 1.46-2.12), and reduce the incidence of aspiration pneumonia (OR =â0.28, 95% CI: 0.15-0.53), incidence of aspiration (OR =0.27, 95% CI: 0.08-0.93) for stroke patients with dysphagia (all P<0.05), o significant difference in the triceps skinfold thickness (TSF) (MD =0.46, 95% CI: -0.24 to 1.19) and arm muscle circumference (MD =0.04, 95% CI: -0.28 to 0.36) between two groups were found (all P>0.05). Egger regression tests indicated that there was no publication bias between included RCTs (all P>0.05). DISCUSSION: Intermittent tube feeding for stroke patients with dysphagia during the recovery period can not only ensure the nutritional supply, but also promote the recovery of swallowing function and reduce the occurrence of aspiration and aspiration associated pneumonia.

BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) is recommended for long-term enteral nutrition. However, long-term nasogastric (NGT) feeding is still commonplace in China. We surveyed Chinese clinicians' opinions toward PEG feeding in order to identify the potential barriers to acceptancy of PEG feeding. METHODS: A self-reported questionnaire was developed and distributed to 600 doctors. Five-point Likert scales were used for most responses. RESULTS: Of 525 respondents, the mainly nutritional support method was NGT while PEG was less used. Doctors working in the tertiary class A hospitals and radiotherapy department were more likely to choose PEG feeding (p = 0.000). Overall, 241 (46%) participants did not know PEG and 284 (54%) have different understanding degree of PEG. Age (p = 0.002), working life (p = 0.044) and professionalism (p = 0.005) were significantly related to the understanding of PEG. Levels of agreement was high (score of 3.47) for using PEG in patients with prolonged stroke-associated dysphagia. There was high agreement level in the statement that PEG was unnecessary when NGT could sustain the basic needs of patients, though better outcome can be predicted with PEG feeding. The highest scoring factor (score of 3.91) that influenced clinicians' choice of PEG was resistance from patients and families and the second one was the poor cooperation among departments (score of 3.80). CONCLUSIONS: Doctors' insufficient knowledge of PEG feeding, resistance from patients and families, poor cooperation among departments, all these factors leading physicians to prefer more conservative treatment to avoid disputes rather than better ones.

Background Timely and effective removal of respiratory secretions is of great significance for tracheotomized patients. The purpose of this study is to investigate the effectiveness of capsaicin nebulization to stimulate cough to promote early clearance of respiratory secretions in tracheotomized patients after hemorrhagic stroke. Method This study implemented a randomized controlled design. Sixty-three patients who were tracheotomized following a hemorrhagic stroke completed this randomized controlled trial. In the control group, 33 cases were given a routine care after tracheotomy. In the intervention group, 30 cases were given a capsaicin solution nebulization in addition to the routine care. The daily sputum output and the number of sputum suctioning were observed. The differences in sputum viscosity, cough function, and Clinical Pulmonary Infection Score (CPIS) were compared between the two groups before and after the intervention. Vital sign changes during capsaicin nebulization and suctioning were compared between the two groups in a pilot study. Results The daily sputum output of the capsaicin intervention group was significantly higher than that of the control group (p < .05). The number of sputum suctioning of capsaicin group was less than that of the control group after intervention (p < .05). The CPIS score of the capsaicin group was lower than that of the control group (p < .05) after a 1-week intervention. Patients' heart rate, respiratory rate, and oxygen saturation during capsaicin nebulization were not statistically different from those during routine sputum suctioning (p > .05). Conclusions Capsaicin atomization-induced cough can effectively promote sputum excretion of hemorrhagic stroke patients undergoing tracheotomy and has a good safety profile. The Clinical Trial registration number of this study is ChiCTR2000037772 (http://www.chictr.org.cns). Supplemental Material https://doi.org/10.23641/asha.16821352.

RNA-binding protein fox-1 homolog 1 (Rbfox-1), an RNA-binding protein in neurons, is thought to be associated with many neurological diseases. To date, the mechanism on which Rbfox-1 worsens secondary cell death in ICH remains poorly understood. In this study, we aimed to explore the role of Rbfox-1 in intracerebral hemorrhage (ICH)-induced secondary brain injury (SBI) and to identify its underlying mechanisms. We found that the expression of Rbfox-1 in neurons was significantly increased after ICH, which was accompanied by increases in the binding of Rbfox-1 to Ca2+/calmodulin-dependent protein kinase II (CaMKIIα) mRNA and the protein level of CaMKIIα. In addition, when exposed to exogenous upregulation or downregulation of Rbfox-1, the protein level of CaMKIIα showed a concomitant trend in brain tissue, which further suggested that CaMKIIα is a downstream-target protein of Rbfox-1. The upregulation of both proteins caused intracellular-Ca2+ overload and neuronal degeneration, which exacerbated brain damage. Furthermore, we found that Rbfox-1 promoted the expression of CaMKIIα via blocking the binding of micro-RNA-124 to CaMKIIα mRNA. Thus, Rbfox-1 is expected to be a promising therapeutic target for SBI after ICH.

The regulation of mRNA localization and local translation play vital roles in the maintenance of cellular structure and function. Many human neurodegenerative diseases, such as fragile X syndrome, amyotrophic lateral sclerosis, Alzheimer's disease, and spinal muscular atrophy, have been characterized by pathological changes in neuronal axons, including abnormal mRNA translation, the loss of protein expression, or abnormal axon transport. Moreover, the same protein and mRNA molecules have been associated with variable functions in different diseases due to differences in their interaction networks. In this review, we briefly examine fragile X syndrome, amyotrophic lateral sclerosis, Alzheimer's disease, and spinal muscular atrophy, with a focus on disease pathogenesis with regard to local mRNA translation and axon transport, suggesting possible treatment directions.
RESUMO
BACKGROUND: To evaluate the current status of fatigue, sleep and physical activity in postoperative patients with pituitary adenoma (PA). METHODS: Postoperative patients undergoing PA resection from November 2017 to November 2018 were identified. A multi-centered survey was conducted with questionnaires on the characteristics of included PA patients, multidimensional fatigue inventory (MFI-20), the Pittsburgh sleep quality index (PSQI) questionnaire, and the international physical activity (IPA) questionnaire. The related scores and potentially influencing factors were analyzed accordingly. RESULTS: A total of 184 patients were included. The time course after operation, PSQI were correlated with the scores of general fatigue, physical fatigue, reduced activity and reduced motivation (all P<0.05); PSQI and IPA, the time course after operation and gender were the independent factors associated with the level of general fatigue (all P<0.05); PSQI, IPA and the time course after operation, adenoma size and gender were the independent factors influencing the level of physical fatigue (all P<0.05); the time course after operation, IPA, PSQI and gender were the independent factor influencing the level of reduced activity (all P<0.05); the time course after operation, IPA, PSQI and adenoma size were the independent factor influencing the level of reduced motivation (all P<0.05); the time course after operation was the independent factor influencing the level of mental motivation (P=0.030). CONCLUSIONS: Fatigue in PA patients after surgery is inversely associated with the time course after surgery and physical activity, future studies on the related interventions are warranted.
