Methods： Totally 120 patients with a diagnosis of UC were recruited and the demographics, clinical data, and blood samples were collected. C-reactive protein（CRP） and erythrocyte sedimentation rate（ESR） concentrations were measured. Every patient accepted pulmonary function test and took chest radiograph（CXR）. Results： Pulmonary function abnormalities were present in 72 of 120 patients. The median（interquartile range） vital capacity（VC）, forced vital capacity（FVC）, forced expiratory volume in 1 s（FEV_1）, carbon monoxide diffusion capacity（DL_∞） of lung, total lung capacity（TLC） and functional residual volume（FRV） were decreased in distal UC and pancolitis compared with ulcerative prochitis（P〈0.0005）. Male patients had increased VC, FEV_1/FVC, and residual volume（RV）/TLC compared with female（P〈0.0005）, but decreased DLCO and carbon monoxide iffusion capacity（KCO） of lung/alveolar ventilation（P〈0.0005）. Age was strongly correlated with RV（Spearman rank correlation coefficient（rs）=–0.57, P〈0.0001）, and RV/TLC（rs=0.48, P〈0.0001）. Age was also correlated with FEV_1/FVC（rs=–0.29, P=0.001）, forced expiratory flow in 75% vital capacity（FEF75%, rs=–0.20, P=0.03）, DLCO（rs=–0.21, P=0.02）, TLC（rs=–0.25, P=0.006）, and FRV（rs=–0.28, P=0.002）. The course of disease was correlated with FEF75%（rs=–0.18, P=0.049） and KCO（rs=–0.19, P=0.036）. Chest radiograph abnormalities were presented in 38 of 120. Pulmonary symptoms were presented in 10 of 120. Other extraintestinal complications were presented in 21 of 120. Conclusions： Pulmonary function impairment was more frequently than other extraintestinal complications in UC patients, which may be affected by sex, age, extent and course of disease. These results may be a scientific basis for the theory of exterior-interior correlation between Lung and Large intestine.展开更多

Under laboratory co...Regulation of gonadal function by gonadotropic hormone (GtH) and gonadotropin-releasing hormone (GnRH) in Channa punctatus was significantly affected by nonlethal levels of Metacid-50 and Carbaryl. Under laboratory conditions, the time-dependent decrease in serum GtH level was higher in Carbaryl-treated fish than in Metacid-50-treated fish. The situation was reversed in the field, with a higher inhibitory effect of Metacid-50 being recorded. On the other hand, pituitary GtH content and GnRH activity were inhibited to a greater extent by Metacid-50 than by Carbaryl under both field and laboratory conditions. The present findings highlight that even low doses of Metacid-50 and Carbaryl are effective enough to cause reproductive damage, as evidenced by homeostatic unbalance of the reproductive regulatory system. 1990 Academic Press.

Methods Sixty cases of post-stroke hand motor impairment were randomly divided into an observation group and a control group, 30 cases in each one. The conventional medication, physical therapy, occupational therapy and other rehabilitation trainings were applied in both groups. In observation group, Zhongzhu （中渚 TE 3） and Waiguan （外关TE 5） were punctured. The assessment was performed with neurologie deficit scoring of the National Institutes of Health Stroke Scale （NIHSS）, hand motor function, walking ability and the modified Barthel index scale of the Activities of Daily Living （ADL） in both groups before and after treatment. Results After treatment, the scores of hand function, walking ability, ADL and NIHSS were improved in both groups as compared with those before treatment （all P〈0.01）. The improvements of hand function, walking ability and ADL ：in observation group were superior to those in control group （all P〈0.05）. Conclusion The conventional medication and rehabilitation trainings combined with acupuncture at Zhongzhu （中渚 TE 3） and Waiguan （外关TE 5） ean obviously improve hand motor function, walking ability, the activities of daily living and rehabilitation efficacy in the patients with post-stroke hand motor impairment.展开更多

Many pathological conditions, such as tissue ischemia, renal function impairment, cardiac function impairment, metabolic syndrome, and inflammatory status, may impact uric acid （UA） metabolism. This study was to assess their potential relations to UA metabolism in heart failure. Methods We retrospectively assessed clinical charac- teristics, echocardiological, renal, metabolic and inflammatory variables selected on the basis of previous evidence of their involvement in cardiovascular diseases and UA metabolism in a large cohort of randomly selected adults with congestive heart failure （n = 553）. By clustering of indices, those variables were explored using factor analysis. Results In factor analysis, serum uric acid （SUA） formed part of a principal cluster of renal functional variables which included serum creatinine （SCr） and blood urea nitrogen （BUN）. Univariate correlation coefficients between variables of patients with congestive heart failure showed that the strongest correlations for SUA were with BUN （r = 0.48, P 〈 0.001） and SCr （r = 0.47, P 〈 0.001）. Conclusions There was an inverse relationship between SUA levels and measures of renal function in patients with congestive heart failure. The strong correlation between SUA and SCr and BUN levels suggests that elevated SUA concentrations reflect an impairment of renal function in heart failure.展开更多

However, little is known regarding face recognition ERP in PD. The present study assessed cognitive function in PD patients using neuropsychological scales and analyzed N170 of visuospatial function impairment （VFI） in PD. Results showed that Montreal cognitive assessment can be used for assessing cognitive impairment when visuospatial functioning is changed during the early stage of PD. Face recognition has clinical significance for detecting changes in visuospatial functioning. However, N170 is not sensitive for detection of VFI in PD, which implies that VFI does not appear in the stage of structure coding in face recognition. In addition, VFI affects face recognition.展开更多

Methods： Ninety-two patients with high-degree atrio-ventricular block and moderately reduced LVEF （ranging from 35% to 50%） were randomly allocated to RVMSP （n=45） and RVAP （n=47）. New York Heart Association （NYHA） functional class, echocardiographic LVEF, and distance during a 6-min walk test （6MWT） were determined at 18 months after pacemaker implantation. Serum levels of N-terminal pro-brain natriuretic peptide （NT-proBNP） were measured using an enzyme-linked immunosorbent assay （ELISA） kit. Results： Compared with baseline, NYHA functional class remained unchanged at 18 months, distance during 6MVVT （485 m vs. 517 m） and LVEF （36.7% vs. 41.8%） were increased, but BNP levels were reduced （2352 pg/ml vs. 710 pg/ml） in the RVMSP group compared with those in the RVAP group, especially in patients with LVEF 35%-40% （for all comparisons, P〈0.05）. However, clinical function capacity and LV function measurements were not significantly changed in patients with RVAP, despite the pacing measurements being similar in both groups, such as R-wave amplitude and capture threshold. Conclusions： RVMSP provides a better clinical utility, compared with RVAP, in patients with high-degree atrioventricular block and moderately depressed LV function whose LVEF levels ranged from 35% to 40%.展开更多

However, most functional magnetic resonance imaging studies have focused on acute changes in brain activation induced by acupuncture. Thus, the time course of the therapeutic effects of acupuncture remains unclear. In this study, 32 patients with amnestic mild cognitive impairment were randomly divided into two groups, where they received either Tiaoshen Yizhi acupuncture or sham acupoint acupuncture. The needles were either twirled at Tiaoshen Yizhi acupoints, including Sishencong（EX-HN1）, Yintang（EX-HN3）, Neiguan（PC6）, Taixi（KI3）, Fenglong（ST40）, and Taichong（LR3）, or at related sham acupoints at a depth of approximately 15 mm, an angle of ± 60°, and a rate of approximately 120 times per minute. Acupuncture was conducted for 4 consecutive weeks, five times per week, on weekdays. Resting-state functional magnetic resonance imaging indicated that connections between cognition-related regions such as the insula, dorsolateral prefrontal cortex, hippocampus, thalamus, inferior parietal lobule, and anterior cingulate cortex increased after acupuncture at Tiaoshen Yizhi acupoints. The insula, dorsolateral prefrontal cortex, and hippocampus acted as central brain hubs. Patients in the Tiaoshen Yizhi group exhibited improved cognitive performance after acupuncture. In the sham acupoint acupuncture group, connections between brain regions were dispersed, and we found no differences in cognitive function following the treatment. These results indicate that acupuncture at Tiaoshen Yizhi acupoints can regulate brain networks by increasing connectivity between cognition-related regions, thereby improving cognitive function in patients with mild cognitive impairment.展开更多

As a part of the medial temporal lobe memory system,the hippocampus is one of the brain regions affected earliest by AD neuropathology,and shows progressive degeneration as a MCI progresses to AD. Currently,no validated biomarkers can precisely predict the conversion from a MCI to AD. Therefore,there is a great need of sensitive tools for the early detection of AD progression. In this review,we summarize the specifi c structural and functional changes in the hippocampus from recent a MCI studies using neurophysiological and neuroimaging data. We suggest that a combination of advanced multi-modal neuroimaging measures in discovering biomarkers will provide more precise and sensitive measures of hippocampal changes than using only one of them. These will potentially affect early diagnosis and disease-modifying treatments. We propose a new sequential and progressive framework in which the impairment spreads from the integrity of fibers to volume and then to function in hippocampal subregions. Meanwhile,this is likely to be accompanied by progressive impairment of behavioral and neuropsychological performance in the progression of a MCI to AD.展开更多

文摘Objective： To investigate the involvement of pulmonary function impairment in ulcerative colitis（UC）, and explore a scientific basis for the Chinese medicine（CM） theory of exterior-interior correlation between Lung（Fei） and Large intestine（Dachang）. Methods： Totally 120 patients with a diagnosis of UC were recruited and the demographics, clinical data, and blood samples were collected. C-reactive protein（CRP） and erythrocyte sedimentation rate（ESR） concentrations were measured. Every patient accepted pulmonary function test and took chest radiograph（CXR）. Results： Pulmonary function abnormalities were present in 72 of 120 patients. The median（interquartile range） vital capacity（VC）, forced vital capacity（FVC）, forced expiratory volume in 1 s（FEV_1）, carbon monoxide diffusion capacity（DL_∞） of lung, total lung capacity（TLC） and functional residual volume（FRV） were decreased in distal UC and pancolitis compared with ulcerative prochitis（P〈0.0005）. Male patients had increased VC, FEV_1/FVC, and residual volume（RV）/TLC compared with female（P〈0.0005）, but decreased DLCO and carbon monoxide iffusion capacity（KCO） of lung/alveolar ventilation（P〈0.0005）. Age was strongly correlated with RV（Spearman rank correlation coefficient（rs）=–0.57, P〈0.0001）, and RV/TLC（rs=0.48, P〈0.0001）. Age was also correlated with FEV_1/FVC（rs=–0.29, P=0.001）, forced expiratory flow in 75% vital capacity（FEF75%, rs=–0.20, P=0.03）, DLCO（rs=–0.21, P=0.02）, TLC（rs=–0.25, P=0.006）, and FRV（rs=–0.28, P=0.002）. The course of disease was correlated with FEF75%（rs=–0.18, P=0.049） and KCO（rs=–0.19, P=0.036）. Chest radiograph abnormalities were presented in 38 of 120. Pulmonary symptoms were presented in 10 of 120. Other extraintestinal complications were presented in 21 of 120. Conclusions： Pulmonary function impairment was more frequently than other extraintestinal complications in UC patients, which may be affected by sex, age, extent and course of disease. These results may be a scientific basis for the theory of exterior-interior correlation between Lung and Large intestine.
文摘Regulation of gonadal function by gonadotropic hormone (GtH) and gonadotropin-releasing hormone (GnRH) in Channa punctatus was significantly affected by nonlethal levels of Metacid-50 and Carbaryl. Under laboratory conditions, the time-dependent decrease in serum GtH level was higher in Carbaryl-treated fish than in Metacid-50-treated fish. The situation was reversed in the field, with a higher inhibitory effect of Metacid-50 being recorded. On the other hand, pituitary GtH content and GnRH activity were inhibited to a greater extent by Metacid-50 than by Carbaryl under both field and laboratory conditions. The present findings highlight that even low doses of Metacid-50 and Carbaryl are effective enough to cause reproductive damage, as evidenced by homeostatic unbalance of the reproductive regulatory system. 1990 Academic Press.

文摘Objective To observe the therapeutic effects of post-stroke hand motor impairment treated with acupuncture at Zhongzhu （中渚 TE 3） and Waiguan （外关TE 5）. Methods Sixty cases of post-stroke hand motor impairment were randomly divided into an observation group and a control group, 30 cases in each one. The conventional medication, physical therapy, occupational therapy and other rehabilitation trainings were applied in both groups. In observation group, Zhongzhu （中渚 TE 3） and Waiguan （外关TE 5） were punctured. The assessment was performed with neurologie deficit scoring of the National Institutes of Health Stroke Scale （NIHSS）, hand motor function, walking ability and the modified Barthel index scale of the Activities of Daily Living （ADL） in both groups before and after treatment. Results After treatment, the scores of hand function, walking ability, ADL and NIHSS were improved in both groups as compared with those before treatment （all P〈0.01）. The improvements of hand function, walking ability and ADL ：in observation group were superior to those in control group （all P〈0.05）. Conclusion The conventional medication and rehabilitation trainings combined with acupuncture at Zhongzhu （中渚 TE 3） and Waiguan （外关TE 5） ean obviously improve hand motor function, walking ability, the activities of daily living and rehabilitation efficacy in the patients with post-stroke hand motor impairment.
文摘Background Hyperuricemia is frequently present in patients with heart failure. Many pathological conditions, such as tissue ischemia, renal function impairment, cardiac function impairment, metabolic syndrome, and inflammatory status, may impact uric acid （UA） metabolism. This study was to assess their potential relations to UA metabolism in heart failure. Methods We retrospectively assessed clinical charac- teristics, echocardiological, renal, metabolic and inflammatory variables selected on the basis of previous evidence of their involvement in cardiovascular diseases and UA metabolism in a large cohort of randomly selected adults with congestive heart failure （n = 553）. By clustering of indices, those variables were explored using factor analysis. Results In factor analysis, serum uric acid （SUA） formed part of a principal cluster of renal functional variables which included serum creatinine （SCr） and blood urea nitrogen （BUN）. Univariate correlation coefficients between variables of patients with congestive heart failure showed that the strongest correlations for SUA were with BUN （r = 0.48, P 〈 0.001） and SCr （r = 0.47, P 〈 0.001）. Conclusions There was an inverse relationship between SUA levels and measures of renal function in patients with congestive heart failure. The strong correlation between SUA and SCr and BUN levels suggests that elevated SUA concentrations reflect an impairment of renal function in heart failure.
文摘Event-related potential （ERP） studies of cognitive function in Parkinson＇s disease （PD） have focused on P300 and N270. However, little is known regarding face recognition ERP in PD. The present study assessed cognitive function in PD patients using neuropsychological scales and analyzed N170 of visuospatial function impairment （VFI） in PD. Results showed that Montreal cognitive assessment can be used for assessing cognitive impairment when visuospatial functioning is changed during the early stage of PD. Face recognition has clinical significance for detecting changes in visuospatial functioning. However, N170 is not sensitive for detection of VFI in PD, which implies that VFI does not appear in the stage of structure coding in face recognition. In addition, VFI affects face recognition.

文摘Objective： We are aimed to investigate whether right ventricular mid-septal pacing （RVMSP） is superior to conventional right ventricular apical pacing （RVAP） in improving clinical functional capacity and left ventricular ejection fraction （LVEF） for patients with high-degree atrio-ventricular block and moderately depressed left ventricle （LV） function. Methods： Ninety-two patients with high-degree atrio-ventricular block and moderately reduced LVEF （ranging from 35% to 50%） were randomly allocated to RVMSP （n=45） and RVAP （n=47）. New York Heart Association （NYHA） functional class, echocardiographic LVEF, and distance during a 6-min walk test （6MWT） were determined at 18 months after pacemaker implantation. Serum levels of N-terminal pro-brain natriuretic peptide （NT-proBNP） were measured using an enzyme-linked immunosorbent assay （ELISA） kit. Results： Compared with baseline, NYHA functional class remained unchanged at 18 months, distance during 6MVVT （485 m vs. 517 m） and LVEF （36.7% vs. 41.8%） were increased, but BNP levels were reduced （2352 pg/ml vs. 710 pg/ml） in the RVMSP group compared with those in the RVAP group, especially in patients with LVEF 35%-40% （for all comparisons, P〈0.05）. However, clinical function capacity and LV function measurements were not significantly changed in patients with RVAP, despite the pacing measurements being similar in both groups, such as R-wave amplitude and capture threshold. Conclusions： RVMSP provides a better clinical utility, compared with RVAP, in patients with high-degree atrioventricular block and moderately depressed LV function whose LVEF levels ranged from 35% to 40%.

文摘Background:Nonalcoholic fatty liver disease(NAFLD)is associated with impaired renal function,and both diseases often occur alongside other metabolic disorders.However,the prevalence and risk factors for impaired renal function in patients with NAFLD remain unclear.The objective of this study was to identify the prevalence and risk factors for renal impairment in NAFLD patients.Methods:All adults aged 18-70 years with ultrasound-diagnosed NAFLD and transient elastography examination from eight Asian centers were enrolled in this prospective study.Liver fibrosis and cirrhosis were assessed by FibroScan-aspartate aminotransferase(FAST),Agile 3+and Agile 4 scores.Impaired renal function and chronic kidney disease(CKD)were defined by an estimated glomerular filtration rate(eGFR)with value of<90 mL/min/1.73 m^(2) and<60 mL/min/1.73 m^(2),respectively,as estimated by the CKD-Epidemiology Collaboration(CKD-EPI)equation.Results:Among 529 included NAFLD patients,the prevalence rates of impaired renal function and CKD were 37.4%and 4.9%,respectively.In multivariate analysis,a moderate-high risk of advanced liver fibrosis and cirrhosis according to Agile 3+and Agile 4 scores were independent risk factors for CKD(P<0.05).Furthermore,increased fasting plasma glucose(FPG)and blood pressure were significantly associated with impaired renal function after controlling for the other components of metabolic syndrome(P<0.05).Compared with patients with normoglycemia,those with prediabetes[FPG≥5.6 mmol/L or hemoglobin A1c(HbA1c)≥5.7%]were more likely to have impaired renal function(P<0.05).Conclusions:Agile 3+and Agile 4 are reliable for identifying NAFLD patients with high risk of CKD.Early glycemic control in the prediabetic stage might have a potential renoprotective role in these patients.

文摘Functional magnetic resonance imaging has been widely used to investigate the effects of acupuncture on neural activity. However, most functional magnetic resonance imaging studies have focused on acute changes in brain activation induced by acupuncture. Thus, the time course of the therapeutic effects of acupuncture remains unclear. In this study, 32 patients with amnestic mild cognitive impairment were randomly divided into two groups, where they received either Tiaoshen Yizhi acupuncture or sham acupoint acupuncture. The needles were either twirled at Tiaoshen Yizhi acupoints, including Sishencong（EX-HN1）, Yintang（EX-HN3）, Neiguan（PC6）, Taixi（KI3）, Fenglong（ST40）, and Taichong（LR3）, or at related sham acupoints at a depth of approximately 15 mm, an angle of ± 60°, and a rate of approximately 120 times per minute. Acupuncture was conducted for 4 consecutive weeks, five times per week, on weekdays. Resting-state functional magnetic resonance imaging indicated that connections between cognition-related regions such as the insula, dorsolateral prefrontal cortex, hippocampus, thalamus, inferior parietal lobule, and anterior cingulate cortex increased after acupuncture at Tiaoshen Yizhi acupoints. The insula, dorsolateral prefrontal cortex, and hippocampus acted as central brain hubs. Patients in the Tiaoshen Yizhi group exhibited improved cognitive performance after acupuncture. In the sham acupoint acupuncture group, connections between brain regions were dispersed, and we found no differences in cognitive function following the treatment. These results indicate that acupuncture at Tiaoshen Yizhi acupoints can regulate brain networks by increasing connectivity between cognition-related regions, thereby improving cognitive function in patients with mild cognitive impairment.

文摘Impaired structure and function of the hippocampus is a valuable predictor of progression from amnestic mild cognitive impairment（a MCI） to Alzheimer＇s disease（AD）. As a part of the medial temporal lobe memory system,the hippocampus is one of the brain regions affected earliest by AD neuropathology,and shows progressive degeneration as a MCI progresses to AD. Currently,no validated biomarkers can precisely predict the conversion from a MCI to AD. Therefore,there is a great need of sensitive tools for the early detection of AD progression. In this review,we summarize the specifi c structural and functional changes in the hippocampus from recent a MCI studies using neurophysiological and neuroimaging data. We suggest that a combination of advanced multi-modal neuroimaging measures in discovering biomarkers will provide more precise and sensitive measures of hippocampal changes than using only one of them. These will potentially affect early diagnosis and disease-modifying treatments. We propose a new sequential and progressive framework in which the impairment spreads from the integrity of fibers to volume and then to function in hippocampal subregions. Meanwhile,this is likely to be accompanied by progressive impairment of behavioral and neuropsychological performance in the progression of a MCI to AD.

文摘BACKGROUND With the growing scholarly and clinical fascination with somatic symptom dis-order(SSD),a bibliometric analysis is lacking.AIM To conduct a bibliometric analysis to investigate the current status and frontiers of SSD.METHODS The documents related to SSD are obtained from the web of science core collection database(WoSCC),and VOSviewer 1.6.16 from January 1,2000 to December 31,2023,and the WoSCC’s literature analysis wire were used to conduct the biblio-metric analysis.RESULTS A total of 567 documents related to SSD were included,and 2325 authors across 947 institutions from 57 countries/regions have contributed to SSD research,published in 277 journals.The most productive author,institution,country and journal were Löwe B,University of Hamburg,Germany,and Journal of Psycho-somatic Research respectively.The first high-cited document was published in the Journal of Psychosomatic Research in 2013 by Dimsdale JE and colleagues,which explored the rationale behind the SSD diagnosis introduction in diagnostic and statistical manual of mental disorders.CONCLUSION In conclusion,the main research hotspots and frontiers in the field of SSD are validity and reliability of the SSD criteria,functional impairment of SSD,and the treatment for SSD.More high-quality studies are needed to assess the diagnosis and treatment of SSD.
文摘Psychosomatic disorders,characterized by significant contributions of psychosocial factors to the pathogenesis and progression of somatic organic diseases or functional impairments(e.g.,diabetes,essential hypertension,asthma,inflammatory bowel disease,and neurodermatitis),present unique diagnostic and therapeutic challenges[1].Traditional diagnostic frameworks,heavily reliant on clinicians’subjective judgment and limited by the qualitative nature of psychological assessments,often result in misdiagnosis or delayed detection.As a cornerstone of the Fourth Industrial Revolution,artificial intelligence(AI)has demonstrated transformative potential in medicine.In psychosomatic medicine,AI leverages advanced data analytics,machine learning,and natural language processing to decipher the intricate interplay between psychological and physiological mechanisms,offering novel tools for diagnosis,treatment,and prevention.However,its clinical integration raises critical ethical and operational concerns that warrant rigorous examination.
基金Pathogen Distribution,Imaging Features,and Clinical Manifestations of Pulmonary Infections in Patients with Impaired Immune Function(Project No.:2023-1-NS-017)。
文摘Objective:To explore the imaging characteristics changes of pulmonary infections in patients with hypo-immunity and analyze the correlation between NLR,PCT levels and their severity.Methods:This study included 80 patients with hypo-immunity and pulmonary infections who were diagnosed and treated at our hospital from October 2022 to October 2024.Imaging examinations were performed on the patients.Subsequently,the patients were divided into a severe group and a mild group based on the severity of their disease.Univariate analysis was conducted,and variables with statistical significance from the univariate analysis were included in a multivariate logistic regression analysis to clarify the correlation between plasma NLR,PCT levels,and their severity.Results:Imaging examinations revealed that ground-glass opacities in the lungs were centered around the hilum,with patchy or map-like distributions accompanied by reticular shadows.The affected areas and normal lung areas were interspersed,with a tendency to merge.Some patients also developed pneumothorax.Ground-glass opacities were the most characteristic manifestation,which could also present as reticular shadows,interstitial thickening,miliary shadows,multiple small nodules,intrathoracic lymphadenopathy,and a small amount of pleural effusion.In the correlation analysis,NLR and PCT were statistically significant in the univariate analysis(p<0.05).When included in the multivariate logistic regression analysis,NLR(OR=2.846,95%CI:2.402-3.358)and PCT(OR=1.958,95%CI:1.554-2.601)were found to be positively correlated with the severity of pulmonary infections in patients with hypo-immunity.Conclusion:The imaging manifestations of patients with impaired immune function are complex and diverse,primarily including patchy,linear,massive,cavitary,and diffuse lesions,among other forms.These manifestations not only assist physicians in identifying the presence of pulmonary infections but also provide crucial information for diagnosing the type,severity,and complications of the infections.The levels of NLR(Neutrophil-to-Lymphocyte Ratio)and PCT(Procalcitonin)exhibit a positive correlation with the severity of pulmonary infections in patients with impaired immune function,warranting significant attention.

文摘Deficits in intrinsic neuronal capacities in the spinal cord,a lack of growth support,and suppression of axonal outgrowth by inhibitory molecules mean that spinal cord injury almost always has devastating consequences.As such,one of the primary targets for the treatment of spinal cord injury is to develop strategies to antagonize extrinsic or intrinsic axonal growth-inhibitory factors or enhance the factors that support axonal growth.Among these factors,a series of individual protein level disorders have been identified during the generation of axons following spinal cord injury.Moreover,an increasing number of studies have indicated that post-translational modifications of these proteins have important implications for axonal growth.Some researchers have discovered a variety of post-translational modifications after spinal cord injury,such as tyrosination,acetylation,and phosphorylation.In this review,we reviewed the post-translational modifications for axonal growth,functional recovery,and neuropathic pain after spinal cord injury,a better understanding of which may elucidate the dynamic change of spinal cord injury-related molecules and facilitate the development of a new therapeutic strategy for spinal cord injury.
