RESUMEN
BACKGROUND: We report a case of eye-penetrating injury in which a massive silicone oil migration into the patient's subconjunctival space and orbit occurred after vitrectomy. CASE SUMMARY: A 30-year-old male patient sought medical attention at Ganzhou People's Hospital after experiencing pain and vision loss in his left eye due to a nail wound on December 9, 2023. Diagnosis of penetrating injury caused by magnetic foreign body retention in the left eye and hospitalization for treatment. On December 9, 2023, pars plana vitrectomy was performed on the left eye for intraocular foreign body removal, abnormal crystal extraction, retinal photocoagulation. Owing to the discovery of retinal detachment at the posterior pole during surgery, silicone oil was injected to fill the vitreous body, following which upper conjunctival bubble-like swelling was observed. Postoperative orbital computed tomography (CT) review indicated migration of silicone oil to the subconjunctival space and orbit through a self-permeable outlet. On December 18, 2023, the patient sought treatment at the First Affiliated Hospital of Nanchang University, China. The patient presented with a pronounced foreign body sensation following left eye surgery. On December 20, 2023, the foreign body was removed from the left eye frame and an intraocular examination was conducted. The posterior scleral tear had closed, leading to termination of the surgical procedure following supplementary laser treatment around the tear. The patient reported a significant reduction in ocular surface symptoms just one day after surgery. Furthermore, a notable decrease in the migration of silicone oil was observed in orbital CT scans. CONCLUSION: The timing of silicone oil injection for an eye-penetrating injury should be carefully evaluated to avoid the possibility of silicone oil migration.
RESUMEN
Inflammation and immunity play important roles in the pathogenesis of ischemic stroke. This study aimed to explore key regulatory genes in acute ischemic stroke (AIS) and their underlying mechanisms to provide new research targets for the diagnosis and treatment of ischemic stroke. We searched for differentially expressed mRNAs and miRNAs in patients with AIS and healthy populations in GEO databases, constructed a miRNA-mRNA network, and screened key miRNAs using least absolute shrinkage and selection operator regression and the support vector machine-recursive feature elimination model. Correlations between key miRNAs and infiltrating immune cells and inflammatory factors were analyzed using CIBERSORT and immunoassays and verified using clinical experiments. Bioinformatics analysis identified hsa-miR-877-5p as a key regulatory miRNA in AIS that can modulate immune and inflammatory responses. In clinical studies, it was verified by quantitative PCR analysis that the expression of hsa-miR-877-5p in the blood of AIS patients was higher than that of the healthy group. Then, enzyme-linked immunosorbent assay revealed that the expression of IL-23 and TNF-α related to inflammation in AIS patients was higher than that of the healthy. Quantitative PCR further found that the relative mRNA expression of IL-23, CXCR3, and TNF-α in AIS group was higher than that of the healthy group. This study may provide a basis for a more comprehensive understanding of the potential mechanism of the occurrence and development of AIS, and hsa-miR-877-5p and its downstream effectors IL-23, CXCR3, and TNF-α may be potential intervention targets in AIS.

BACKGROUND: A few reports have revealed induction of rhabdomyolysis by a red yeast rice (RYR) supplement or by RYR in combination with abiraterone (an androgen biosynthesis inhibitor). CASE SUMMARY: A 76-year-old man presented with progressive limb weakness, muscle soreness, and acute kidney injury (AKI). He had been taking the anti-prostate cancer drug abiraterone for 14 mo and had added a RYR supplement 3 mo before symptom onset. After being diagnosed with rhabdomyolysis-induced AKI, the patient discontinued these drugs and responded well to hemodialysis and hemoperfusion. After 23 d of treatment, creatine kinase levels returned to normal and serum creatinine levels decreased. CONCLUSION: We speculate that statins, the main lipid-lowering component of RYR, or a combination of statins and abiraterone, will increase the risk of rhabdomyolysis.
RESUMEN
OBJECTIVE: Cognitive impairment, one of the most prevalent complications of trigeminal neuralgia, is troubling for patients and clinicians due to limited therapeutic options. Curcumin shows antinociception and neuroprotection pharmacologically, suggesting that it may have therapeutic effect on this complication. This study aimed to investigate whether curcumin alleviates orofacial allodynia and improves cognitive impairment by regulating hippocampal CA1 region synaptic plasticity in trigeminal neuralgia. METHODS: A mouse model of trigeminal neuralgia was established by partially transecting the infraorbital nerve (pT-ION). Curcumin was administered by gavage twice daily for 14 days. Nociceptive thresholds were measured using the von Frey and acetone test, and the cognitive functions were evaluated using the Morris water maze test. Dendritic spines and synaptic ultrastructures in the hippocampal CA1 area were observed by Golgi staining and transmission electron microscopy. RESULTS: Curcumin intervention increased the mechanical and cold pain thresholds of models. It decreased the escape latency and distance to the platform and increased the number of platform crossings and dwell time in the target quadrant of models, and improved spatial learning and memory deficits. Furthermore, it partially restored the disorder of the density and proportion of dendritic spines and the abnormal density and structure of synapses in the hippocampal CA1 region of models. CONCLUSION: Curcumin alleviates abnormal orofacial pain and cognitive impairment in pT-ION mice by a mechanism that may be related to the synaptic plasticity of hippocampal CA1, suggesting that curcumin is a potential strategy for repairing cognitive dysfunction under long-term neuropathic pain conditions.

OBJECTIVE: To explore the effect of early swallowing training on postoperative outcomes of patients who had undergone oral cancer surgery plus free flap reconstruction. SUBJECTS AND METHODS: In this prospective, randomized controlled trial, 121 patients who had undergone oral cancer surgery plus free flap reconstruction were randomly assigned to the control (n = 59) or intervention group (n = 62). The control group underwent routine nursing measures. The intervention group received swallowing training on the sixth postoperative day. On the 15th day and 1 month after surgery, the swallowing function (Mann Assessment of Swallowing Ability-Oral Cancer [MASA-OC] score), weight loss rate, time of nasogastric tube removal, and quality of life were evaluated. RESULTS: Patients in the intervention group had higher MASA-OC scores and better weight loss rates than those in the control group on the 15th day (MASA-OC: p = 0.014, weight loss: p < 0.001) and 1 month (both p < 0.001) after surgery. The time of nasogastric tube removal and the quality of life was statistically significant between groups (p < 0.001). CONCLUSION: Early swallowing training improves the swallowing function, nutritional status, and quality of life and shortens the indwelling time of nasogastric tube of patients who have undergone oral cancer surgery plus free flap reconstruction.
RESUMEN
Post-stroke depression, a common complication after stroke, severely affects the recovery and quality of life of patients with stroke. Owing to its complex mechanisms, post-stroke depression treatment remains highly challenging. Hippocampal synaptic plasticity is one of the key factors leading to post-stroke depression; however, the precise molecular mechanisms remain unclear. Numerous studies have found that neurotrophic factors, protein kinases and neurotransmitters influence depressive behaviour by modulating hippocampal synaptic plasticity. This review further elaborates on the role of hippocampal synaptic plasticity in post-stroke depression by summarizing recent research and analysing possible molecular mechanisms. Evidence for the correlation between hippocampal mechanisms and post-stroke depression helps to better understand the pathological process of post-stroke depression and improve its treatment.

Acute ischemic stroke (AIS) is associated with high rates of disability and mortality, exerting a substantial impact on overall survival and health-related quality of life. Treatment of AIS remains challenging given that the underlying pathologic mechanisms remain unclear. However, recent research has demonstrated that the immune system plays a key role in the development of AIS. Numerous studies have reported infiltration of T cells into ischemic brain tissue. While some types of T cells can promote the development of inflammatory responses and aggravate ischemic damage in patients with AIS, other T cells appear to exert neuroprotective effects via immunosuppression and other mechanisms. In this review, we discuss the recent findings regarding the infiltration of T cells into ischemic brain tissue, and the mechanisms governing how T cells can facilitate tissue injury or neuroprotection in AIS. Factors influencing the function of T cells, such as intestinal microflora and sex differences, are also discussed. We also explore the recent research on the effect of non-coding RNA on T cells after stroke, as well as the potential for specifically targeting T cells in the treatment of stroke patients.

OBJECTIVE: Determine the safety and effectiveness of a nasogastric tube removal plan designed to shorten nasogastric tube indwelling time after oral cancer surgery plus free flap reconstruction. MATERIALS AND METHODS: A parallel randomized clinical trial was conducted from May 2021 to December 2021 at Peking University School of Stomatology. Volunteers (n = 128) were separated into four groups: non-tracheostomy control and intervention groups and tracheostomy control and intervention groups. Control patients received the conventional nasogastric tube removal plan. Non-tracheotomy intervention patients were asked to swallow 5 ml of water on the first postoperative day. If there was no coughing, they were allowed progressively increasing amounts of water for the following 2 days. The nasogastric tube was removed only after ensuring level I/II performance on the Watian water swallowing test, no "wet voice" after drinking water, no marked decrease in blood oxygen saturation after drinking, and satisfactory daily oral nutritional intake. Tracheotomy intervention patients received the same protocol plus an additional Watian water swallowing test after tracheal tube removal. RESULTS: Nasogastric tube removal time was earlier in the intervention subgroups than in control subgroups: 5.0 ± 2.3 days versus 7.8 ± 3.9 days (p = 0.001) in non-tracheostomy patients and 9.8 ± 1.1 days versus 16.2 ± 13.0 days (p = 0.049) in tracheostomy patients. Incidence of wound complications and daily food intake were comparable between the groups. The incidence of pneumonia was lower in the tracheostomy intervention group than in the tracheostomy control group (12.5% vs. 3.1%, p = 0.162). Pharyngeal pain score was lower in tracheotomy intervention patients than in tracheotomy control patients (p = 0.029). Postoperative hospital stay was shorter in tracheotomy intervention patients than in tracheotomy control patients (p = 0.005). CONCLUSIONS: On the basis of ensuring safety and effectiveness, patients undergone free flap reconstruction for oral cancer could be offered oral intake early after surgery, which will not increase the incidence of wound complications and pneumonia or adversely affecting the oral intake of the patients; it can also help minimize pharyngeal pain and shorten postoperative hospital stay of patients with a tracheotomy. LEVEL OF EVIDENCE: 2 Laryngoscope, 133:1382-1387, 2023.

Machine learning methods are a novel way to predict and rank donors' willingness to donate blood and to achieve precision recruitment, which can improve the recruitment efficiency and meet the challenge of blood shortage. We collected information about experienced blood donors via short message service (SMS) recruitment and developed 7 machine learning-based recruitment models using PyCharm-Python Environment and 13 features which were described as a method for ranking and predicting donors' intentions to donate blood with a floating number between 0 and 1. Performance of the prediction models was assessed by the Area under the receiver operating characteristic curve (AUC), accuracy, precision, recall, and F1 score in the full dataset, and by the accuracy in the four sub-datasets. The developed models were applied to prospective validations of recruiting experienced blood donors during two COVID-19 pandemics, while the routine method was used as a control. Overall, a total of 95,476 recruitments via SMS and their donation results were enrolled in our modelling study. The strongest predictor features for the donation of experienced donors were blood donation interval, age, and donation frequency. Among the seven baseline models, the eXtreme Gradient Boosting (XGBoost) and Support vector machine models (SVM) achieved the best performance: mean (95%CI) with the highest AUC: 0.809 (0.806-0.811), accuracy: 0.815 (0.812-0.818), precision: 0.840 (0.835-0.845), and F1 score of XGBoost: 0.843 (0.840-0.845) and recall of SVM: 0.991 (0.988-0.994). The hit rate of the XGBoost model alone and the combined XGBoost and SVM models were 1.25 and 1.80 times higher than that of the conventional method as a control in 2 recruitments respectively, and the hit rate of the high willingness to donate group was 1.96 times higher than that of the low willingness to donate group. Our results suggested that the machine learning models could predict and determine the experienced donors with a strong willingness to donate blood by a ranking score based on personalized donation data and demographical details, significantly improve the recruitment rate of blood donors and help blood agencies to maintain the blood supply in emergencies.

Despite extensive research in recent decades, knowledge of the pathophysiology of depression in neural circuits remains limited. Recently, the lateral habenula (LHb) has been extensively reported to undergo a series of adaptive changes at multiple levels during the depression state. As a crucial relay in brain networks associated with emotion regulation, LHb receives excitatory or inhibitory projections from upstream brain regions related to stress and cognition and interacts with brain regions involved in emotion regulation. A series of pathological alterations induced by aberrant inputs cause abnormal function of the LHb, resulting in dysregulation of mood and motivation, which present with depressive-like phenotypes in rodents. Herein, we systematically combed advances from rodents, summarized changes in the LHb and related neural circuits in depression, and attempted to analyze the intrinsic logical relationship among these pathological alterations. We expect that this summary will greatly enhance our understanding of the pathological processes of depression. This is advantageous for fostering the understanding and screening of potential antidepressant targets against LHb.
RESUMEN
Trigeminal neuralgia (TN) is a peripheral nerve disorder often accompanied by abnormalities in mood. The lateral habenula (LHb) plays important roles in the modulation of pain and emotion. In the present study, we investigated the involvement of the LHb in the mechanisms underlying allodynia and anxiety induced by partial transection of the infraorbital nerve (pT-ION) in mice. Our results indicated that pT-ION induced persistent orofacial allodynia and anxiety-like behaviors, which were correlated with increased phosphorylation of N-Methyl D-aspartate receptor (NMDAR) subtype 2B (p-NR2B) and Ca2+/calmodulin-dependent protein kinase II (p-CaMKII) in LHb neurons. Bilateral inhibition of NMDARs and CaMKII in the LHb attenuated the allodynia and anxiety-like behavior induced by pT-ION. Furthermore, bilateral activation of NMDARs in the LHb increased the expression of p-NR2B and p-CaMKII and induced orofacial allodynia and anxiety-like behaviors in naive mice. Adeno-associated virus (AAV)-mediated expression of hM3D(Gq) in CaMKII+ neurons of the bilateral LHb, followed by clozapine-N-oxide (CNO) administration, also triggered orofacial allodynia and anxiety-like behaviors in naïve mice with successful virus infection in LHb neurons (verified based on immunofluorescence). In conclusion, these findings suggest that activation of NMDA/CaMKII signaling in the LHb contributes to the occurrence and development of TN and related anxiety-like behaviors. Therefore, suppressing the activity of CaMKII+ neurons in the bilateral LHb by targeting NMDA/CaMKII may represent a novel strategy for treating pain and anxiety associated with TN.
RESUMEN
Objective: Trigeminal neuralgia (TN), one of the most severe and debilitating chronic pain conditions, is often accompanied by mood disorders, such as anxiety and depression. Electroacupuncture (EA) is a characteristic therapy of Traditional Chinese Medicine with analgesic and anxiolytic effects. This study aimed to investigate whether EA ameliorates abnormal TN orofacial pain and anxiety-like behavior by altering synaptic plasticity in the hippocampus CA1. Materials and methods: A mouse infraorbital nerve transection model (pT-ION) of neuropathic pain was established, and EA or sham EA was used to treat ipsilateral acupuncture points (GV20-Baihui and ST7-Xiaguan). Golgi-Cox staining and transmission electron microscopy (TEM) were administrated to observe the changes of synaptic plasticity in the hippocampus CA1. Results: Stable and persistent orofacial allodynia and anxiety-like behaviors induced by pT-ION were related to changes in hippocampal synaptic plasticity. Golgi stainings showed a decrease in the density of dendritic spines, especially mushroom-type dendritic spines, in hippocampal CA1 neurons of pT-ION mice. TEM results showed that the density of synapses, membrane thickness of the postsynaptic density, and length of the synaptic active zone were decreased, whereas the width of the synaptic cleft was increased in pT-ION mice. EA attenuated pT-ION-induced orofacial allodynia and anxiety-like behaviors and effectively reversed the abnormal changes in dendritic spines and synapse of the hippocampal CA1 region. Conclusion: EA modulates synaptic plasticity of hippocampal CA1 neurons, thereby reducing abnormal orofacial pain and anxiety-like behavior. This provides evidence for a TN treatment strategy.
RESUMEN
OBJECTIVES: Dysphagia is a common and serious complication in patients with oral cancer after free flap transplantation (OC-FFT), which seriously affects their quality of life. Studies have found swallowing rehabilitation can improve the swallowing ability of these patients, but the studies have design deficiencies. This study's purpose was to test the effectiveness of personalized swallowing rehabilitation for this patient population. MATERIALS AND METHODS: This is a cluster randomized, non-blind, controlled clinical trial. Participants were 68 OC-FFT patients randomly assigned to intervention (n = 34) or control (n = 34) groups. The control group received routine nursing and health education, while the intervention group received personalized swallowing rehabilitation twice a day for 10 days, based on the results of the Mann Assessment of Swallowing Ability-Oral Cancer (MASA-OC). On the 6th and 15th days and 1 month after the operation, MASA-OC scores and percentage weight loss were measured, and the removal time to nasogastric tube was also recorded. The quality of life was evaluated 1 month after the operation. RESULTS: On day 15 and 1 month after the operation, MASA-OC scores were higher and the percentage weight loss was lower in the intervention group than the control group (P < 0.05). The removal time of the nasogastric tube was shorter (P < 0.05), and the quality of life at 1 month was better in the intervention group (P < 0.05). CONCLUSION: Personalized swallowing rehabilitation can improve patients' swallowing after OC-FFT, promote the early removal of the nasogastric tube, and improve nutritional status and quality of life.

Swallowing disorder is one of the most common postoperative complications for oral cancer patients and seriously influences quality of life. Limited attention has been paid to evaluating swallowing training measures in postoperative oral cancer patients. This study systematically reviewed swallowing training measures for these patients. A comprehensive search strategy was undertaken across various databases for studies published between database inception and 15 June 2021. Raters independently judged titles, abstracts and full articles for selection according to inclusion and exclusion criteria. The included literature was evaluated for quality and data were extracted. Meta-analyses were conducted using RevMan 5.3. Ten intervention studies (four randomized controlled trials and six quasi-experimental studies) involving 588 patients were identified. Across the studies, most started in the early postoperative stage; however, there were differences in starting time, training time and duration, and type of training. We summarized four training methods: oral exercise, oral sensory stimulation, compensatory strategies and protective airway manoeuvres. The meta-analysis indicated that swallowing training could improve patients' swallowing function and quality of life in the short term, but the long-term effects were not obvious. Swallowing training mostly occurred in the early postoperative period and training measures were often used in combination. The timing, frequency and content of interventions varied between studies, and the effectiveness of any single measure was unclear. High-quality randomized controlled trials are necessary to study the efficacy and clinical applicability of various training measures, to provide a theoretical basis for their optimal selection and to develop a standardized training programme for postoperative oral cancer patients.

BACKGROUND This study aimed to investigate frontoparietal network (FPN) dysfunction in participants with migraine without aura (MwoA). MATERIAL AND METHODS We selected 48 age-, sex-, and education level-matched graduate students (24 participants with MwoA [MwoA group] and 24 healthy controls). RS-fMRI and independent component analysis were used to examine the FPN and to compare abnormal encephalic regional homogeneity values. The Mindful Attention Awareness Scale (MAAS), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), and Self-Rating Scale of Sleep (SRSS) were used to evaluate attention, anxiety, depression, and sleep, respectively. Pearson's correlation was applied to evaluate the association between abnormal brain areas and the scores for each scale. RESULTS Neural function activity in encephalic regions of FPN showed abnormal changes in the MwoA group. The MwoA group had significantly lower MAAS scores (P<0.001), higher SAS scores (P<0.001), and higher SDS (P=0.06) and SRSS scores (P=0.26). In the MwoA group, functional activity of the right parietal lobule in the left FPN was positively correlated with MAAS scores (P=0.01) and negatively correlated with SAS (P=0.02). The orbital part of left inferior frontal gyrus activity in the right FPN was positively correlated with SDS (P=0.04) and SRSS (P<0.001). Right superior marginal gyrus activity in the right FPN was positively correlated with SDS (P=0.02). CONCLUSIONS Abnormal FPN function was correlated with attention, anxiety, depression, and sleep status in the MwoA group. These results offer further insights into the evaluation and treatment of MwoA.

OBJECTIVE: There is lack of standardized management and mobilization strategies after oral and maxillofacial reconstruction surgery. We used prospective randomized controlled trials to explore improvements in postoperative mobilization protocol in such patients. METHODS: A total of 149 patients were randomly divided into tracheotomy control group A (38 cases) and test group A (37 cases), nontracheotomy control group B (38 cases) and test group B (36 cases). Test group patients sat up in bed on the 2nd day after surgery and performed off-bed activity on the 3rd day, whereas control group patients sat up in bed on the 4th day postoperatively and performed off-bed activity on the 6th day. Objective evaluation included free flap success rate, postoperative complications, sleep time, and catheter removal time, among other parameters. Subjective evaluation included postoperative pain and comfort evaluation. RESULTS: The success rate of free flaps was 97.3% in test group A and 100% in the other groups. In terms of mean sleep time, 4.6 ± 1.0 h in test group A, which was longer than 4.1 ± 1.0 h in control group A (P = 0.034); 5.7 ± 1.4 h in test group B, which was longer than 4.9 ± 1.7 h in control group B (P = 0.026). Early activity makes catheter removal time (tracheal incision, nasogastric tube, urethral catheter) shorter and gets higher comfort evaluation scores in both test groups versus control groups (P < 0.05). CONCLUSIONS: The early mobilization protocol for patients undergoing free flap reconstruction was safe, and can effectively improve sleep, shorten the catheter indwelling time, and increase the patient's comfort level.
