The long-term efficacy and complications of implantable diaphragm pacer (IDP) in a child with cervical spinal cord injury (CSCI) in the Department of Spinal and Neural Functional Reconstruction, China Rehabilitation Research Center in September 2022 were retrospective analyzed.A male child had quadriplegia without an obvious cause at the age of 12 years, and he was then lived completely with the assistance of mechanical ventilation.At the age of 14 years, he could wean off the ventilator in unilateral diaphragmatic pacing mode.However, mechanical ventilation was re-given for months after 5 years due to pneumonia, and then the IDP was re-given with the self-felt decreased pacing effect.After hospitalization, the patient was examined with mild diaphragmatic atrophy, secondary flat chest, and mild scoliosis.After optimization of the transdiaphragmatic pacing threshold and rehabilitation, his respiratory function improved.IDP can be used in CSCI for long time, while flat chest and scoliosis that limited the expansion of the lungs should be considered.At the meantime, the increased abdominal spasm affected the abdominal compliance, leading to the decrease in the efficiency of the diaphragm.

Objective To analyze the current status,research hotspots and development trends in the field of immune responses in the microenvironment after spinal cord injury(SCI). Methods Literatrues about immune responses in the microenvironment after SCI were searched from CNKI and the Web of Science Core Collection,from inception to March,2024.VOSviewer and CiteSpace were used to conduct a vi-sual analysis of authors,countries,institutions,journals,co-cited references and keywords. Results A total of 152 Chinese and 455 English studies were included.The number of publications increased annually,and China and the United States were leading research efforts in this field.In the Chinese literature,Zhu Yue was the most prolific author,and China Medical University was the leading institution.In the English literature,Phil-lip Popovich was the most prolific and highly cited author,and Ohio State University was the leading institution.Journal of Neuroscience and Experimental Neurology were identified as key journals.The research hotspots in both languages focused on immune activation,inflammatory response and functional recovery.Researches on stem cell transplantation,macrophage and traditional Chinese medicine were particularly prominent in the regu-lation of immune responses after SCI. Conclusion Immune responses in the microenvironment have emerged as a central focus in SCI research.The emphasis of current researches is shifting from mechanistic exploration to the investigation of immunomodulatory strate-gies,with several cutting-edge technologies showing significant potential in this regard.Moving forward,increas-ing collaboration across regions and institutions are essential to promote information sharing,accelerate scientific progress,and facilitate clinical translation,ultimately enhance patient rehabilitation outcomes.

Snakebite is a common clinical emergency with the characteristics of acute onset,rapid changes in condition,and high disability and mortality rates.In addition to the common systemic and local tissue damage,snake envenomation can cause significant complications,including immediate and delayed effects.These complications are the main causes of disability and even death caused by snakebites,which seriously affect the long-term prognosis and quality of life.This article summarizes the symptoms,diagnosis,and treatment of snakebite complications from the aspects of blood,nervous,motor,endocrine,and reproductive systems and other aspects to provide references for effective and precise treatment of snakebite in clinical practice.

Inflammatory skin diseases(ISD)are characterized by persistent inflammatory cell infiltration and lingering and intractable skin lesions.At present,corticosteroids are the main drugs used in the treatment of ISD.However,due to the characteristics of recurrent and intractable ISD,long-term use of these hormone drugs may cause serious side effects in patients.In recent years,increasingly more studies are confirming that bee venom has significant anti-inflammatory,anti-apoptosis,anti-fibrosis,antibacterial,and other effects and could effectively treat ISD.In this paper,the main active components and anti-inflammatory mechanisms of bee venom are reviewed.The latest attempts to use bee venom for acne,atopic dermatitis,psoriasis,urticaria,and systemic lupus erythematosus are discussed,providing a reference for basic research and the clinical treatment of ISD.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

ObjectiveTo investigate the neurological outcome of children with dance-associated spinal cord injury without radiographic abnormality (SCIWORA) and explore its related factors and predictive model. MethodsFrom July, 2012 to January, 2022, 75 children with dance-associated SCIWORA hospitalized in Beijing Bo'ai Hospital were divided into improved group (n = 14) and non-improved group (n = 61) according to the American Spinal Injury Association Impairment Scale (AIS) grade a year later, and the related factors were analyzed. ResultsAll patients were girls aged four to ten years. Most of them were complete spinal cord injuries (52/75, 69%). The time of injury to rehabilitation (OR = 0.926, P = 0.046, 95%CI 0.858 to 0.999), the existing tendon reflex (OR = 46.915，P = 0.012, 95%CI 2.333 to 943.616) and muscle tension (OR = 8.932，P = 0.044，95%CI 1.063~75.067) were correlated with the AIS grade improvement. The combination of time of injury to rehabilitation, tendon reflex and muscle tone existing may predict the improvement of AIS (AUC = 0.953, P < 0.001，95%CI 0.878 to 0.989), the sensitivity and specificity were 100% and 83.61%, respectively. ConclusionThe neurological outcome of children with dance-associated SCIWORA is poor. Rehabilitation training as soon as possible is beneficial to the neurological recovery. Tendon reflexe and muscle tone existing at admission are closely related to improvement of neurological outcome, which could be used as potential indicators.

Objective:To analyze the factors influencing dysphagia after an injury to the cervical spinal cord (CPCI) to provide a basis for clinical screening and intervention.Methods:A total of 110 CPCI patients with dysphagia were divided into a severe dysphagia group ( n=19), a mild dysphagia group ( n=35), and a control group ( n=56) according to their functional oral intake scale scores. Data on gender, age, level of injury, degree of damage, duration of injury, causes of injury, surgical mode, tracheotomy status, occurrence of pneumonia and pharynx swelling were collected. Univariate and multivariate logistic regressions were evaluated to identify factors affecting swallowing. Results:The regressions highlighted age, the severity of the spinal cord injury, tracheotomy status, and the occurrence of pneumonia and pharyngeal swelling during hospitalization as the best predictors of swallowing difficulties. Multifactoral logistic regression analysis revealed that undergoing tracheotomy and catching pneumonia during hospitalization were major risk factors for severe dysphagia.Conclusions:Tracheotomy and pneumonia during hospitalization are useful predictors of severe dysphagia after a cervical spinal cord injury.

Nicotinamide mononucleotide (NMN) is an important precursor in conversing nicotinamide adenine dinucleotide (NAD +) in the body. By elevating NAD + level in the body, NMN enhances the hydrogen transfer function of NAD + in biological processes, promotes the synthesis of proteins and polysaccharides, improves substance transportation and regulatory efficiency, and enhances metabolic functions. Specifically, in central nervous system disease, NMN exerts neuroprotective effect through antioxidation, anti-inflammation, mitochondrial protection, and prevention of neuronal and axonal degeneration. This review focuses on the therapeutic role of NMN in common central nervous system diseases and their neuroprotective mechanisms, so as to further understand the role of NMN in central nervous system diseases, and provide references for predicting therapeutic targets and screening therapeutic drugs for central nervous system diseases.

Objective:To analyze the clinical data on hospitalized spinal cord injury patients with calf muscle vein thromboses (MCVTs) seeking prevention and treatment techniques.Methods:The medical records of 423 patients with spinal cord injury were collected. Those with MCVT constituted the observation group, while those without served as controls. Their clinical data were compared.Results:The risk factors for MCVT were screened in logistic regression analyses. The results showed that age, an ASIA grade of A or B, spinal fusion, preventive anticoagulation, physiotherapy treatment and a homocysteine level >15μmol/L were risk factors for the occurrence of a MCVT.Conclusions:Age, an ASIA grade of A or B, spinal fusion or an elevated serum homocysteine level are all risk factors for MCVT. Active anticoagulation and physical therapy may reduce the risk.

Objective To explore the value of plasma histones in predicting the prognosis of sepsis patients. Methods The patients with sepsis admitted to intensive care unit (ICU) of Subei People's Hospital of Jiangsu Province Affiliated to Yangzhou University from May 2016 to June 2018 were enrolled as the research subjects, and healthy volunteers were selected as healthy control at the same period. The plasma levels of histones, cardiac troponin I (cTnI), N-terminal pro-brain natriuretic peptide (NT-proBNP), sequential organ failure assessment (SOFA) score, lactate (Lac), procalcitonin (PCT) on admission 24 hours, and use of vasoconstrictor agents, the length of ICU stay and ICU mortality were recorded. The patients were divided into survival group and death group according to the prognosis, and the differences of each index between the two groups were compared. Multivariate binary Logistic regression analysis was carried out to identify the independent risk factors of death. The correlation between histone and the levels of cTnI, NT-proBNP, PCT and Lac was analyzed. The value of plasma histone, cTnI, NT-proBNP, PCT and Lac in predicting the prognosis of patients was analyzed by receiver operating characteristic (ROC) curve. According to the threshold value of histone in predicting prognosis, the patients were divided into two groups, and the differences of various indicators between the two groups were compared. Results ① A total of 93 sepsis patients were included, with 29 cases of ICU death, and the mortality was 31.2%. ② Compared with the healthy control group, histones, cTnI, NT-proBNP were significant increased, besides, histones, cTnI in the death group were further increased compared with the survival group;in addition, SOFA, proportion of vasoconstrictor use were also significant higher than those in the survival group [histones (mg/L): 0.33 (0.28,0.45) vs. 0.22 (0.17,0.29), cTnI (μg/L): 0.25±0.13 vs. 0.20±0.08, SOFA: 11 (8, 12) vs. 9 (8, 11), the rate of vasopressor use: 93.1% (27/29) vs. 68.8% (44/64), all P < 0.05]. Statistically significant indicators between the two groups were included in multivariate binary Logistic regression analysis. The result showed that the independent risk factors affecting the prognosis of patients were the rate of vasopressor use [odds ratio (OR) = 5.277, P = 0.043] and the level of histone (OR = 79.244, P = 0.036). ③ The plasma histone level were positively correlated with cTnI (r = 0.577, P = 0.000), SOFA (r = 0.469, P = 0.000), NT-proBNP (r = 0.349, P = 0.001) and Lac (r = 0.357, P = 0.000), while there was no significant correlation between histone and PCT (r = 0.133, P = 0.205). ④ ROC curve analysis showed that the area under ROC curve (AUC) of histone predicting prognosis was 0.769 (P = 0.000); when the cut-off point was 0.30 mg/L, the sensitivity and specificity were 72.4% and 81.2% respectively. The AUC of SOFA score was 0.653 (P = 0.018), and the sensitivity and specificity were 58.6% and 70.3% respectively when the cut-off point was 10.50; while cTnI, NT-proBNP, Lac and PCT had little value in predicting the prognosis of patients. ⑤ Compared with the group with histone level lower than 0.3 mg/L, the group with histones level greater than 0.3 mg/L had higher SOFA score, more doses of vasopressor, higher cTnI, NT-proBNP, Lac and PCT levels, and higher ICU mortality [SOFA: 11 (10, 12) vs. 9 (8, 10), use of vasopressor: 84.8% (28/33) vs. 76.7% (46/60), cTnI (μg/L): 0.28 (0.19, 0.32) vs. 0.18 (0.12, 0.22), NT-proBNP (ng/L): 3 624.0 (2 800.0, 5 260.0) vs. 2 512.0 (1 361.8, 3 590.8), Lac (mmol/L): 2.25 (1.85, 3.50) vs. 1.60 (1.25, 2.35), PCT (μg/L): 2.10 (1.30, 4.03) vs. 1.60 (1.26, 2.33), ICU mortality: 48.5% (16/33) vs. 21.7% (13/60), all P < 0.05], while no statistical difference in the length of ICU stay was found. Conclusions The independent risk factors for ICU mortality of sepsis patients were high histone level and the use of vasopressor. Plasma histone can be regarded as an indicator in predicting the prognosis of patients with sepsis.
