ABSTRACT

Respiratory sarcopenia is a syndrome characterized by decreased respiratory muscle strength and/or respiratory function on the basis of systemic sarcopenia accompanied by decreased respiratory muscle mass.As aging progresses, respiratory sarcopenia exacerbates respiratory disability in the elderly, affecting daily activities of the elderly which result in the decline of the quality of life.Exploring the screening and evaluation methods of respiratory sarcopenia and sarcopenic disability is helpful to optimize individualized treatment and management.For patients with various stages of respiratory sarcopenia and sarcopenic respiratory disability, the comprehensive intervention strategy based on nutrition and rehabilitation can delay the disease process and improve the quality of life.

ABSTRACT

Objective:To analyze the clinic-pathological features and surgical outcomes of adult patients with hypothalamic gliomas.Methods:The adult cases pathologically confirmed as hypothalamic gliomas were analyzed from October, 2011 to January, 2022 in Beijing Tiantan Hospital.Results:There were 32 adult cases with hypothalamic gliomas, including 16 males and 16 females. Tumor was located in the hypothalamus in 6 cases, in the hypothalamus plus optic chiasma/nerve in 6 cases, in the hypothalamus plus thalamus in 9 cases, and in the hypothalamus plus the third ventricle in 11 cases. Pre-operative hydrocephalus was found in 20 cases. Five patents underwent stereotactic biopsy, 27 patients underwent craniotomy, and 11 patients underwent shunt surgery for hydrocephalus. Of 27 patients with craniotomy, trans-callosal approach was chosen for 9 patients, trans-cortical for 8 patients, via pterion approach for 4 patients, via lateral sub-frontal approach for 4 patients, via fissurae interhemisphaerica for 1 patient, and trans-sphenoidal approach for 1 patient. Twenty-two patients received gross-total or subtotal resection, 5 patients received partial resection. All the patients were pathologically confirmed, including 9 patients with high-grade and 23 patients with low-grade gliomas. Six patients died within 3 months after craniotomy, 8 patients suffered from endocrine dysfunction, 7 patients suffered from electrolyte disturbance, and 5 patients suffered from hydrocephalus. They were followed for 0.7-110.0 months, with 5-year progression-free survival rate of 63.8% and 5-year overall survival rate of 53.9% for all patients. The 5-year progression-free survival rate was 83.3% and the 5-year overall survival rate was 72.8% for low-grade gliomas.Conclusions:The peri-operative mortality is high for adult patients with hypothalamic gliomas, and protection of the hypothalamic function is important. Patients with low-grade hypothalamic gliomas have good prognoses.

ABSTRACT

Objective:To explore the temporal and spatial changes of the whole brain during the picture naming tasks and the influence of different semantic similarity in the blocked-cyclic paradigm.Methods:Ten healthy right-handed adults were selected.The blocked-cyclic paradigm is divided into two naming tasks consist of related and unrelated pictures.The brain activation of the whole brain in different time windows was recorded by magnetoencephalography(MEG) during the picture naming tasks.Results:In the visual-related time windows, the dominant regions appeared in the related picture naming task, located in left frontal pole (1.421±0.468), right frontal pole (1.431±0.435), left orbitofrontal gyrus(1.601±0.620), right orbitofrontal gyrus (1.567±0.556), left superior frontal gyrus (1.899±0.062), right superior parietal gyrus (5.218±0.678) and left lingual gyrus (5.016±0.088) compared with the unrelated picture naming task (1.038±0.217, 1.131±0.235, 1.312±0.316, 1.253±0.340, 1.710±0.151, 4.538±0.478, 4.275±0.251), the differences were statistically significant ( P<0.05). In the semantic-related time windows, the dominant regions appeared in the unrelated picture naming task, located in left paracentral lobule (3.176±0.392), right cuneus (4.190±0.330), left posterior cingulate (2.430±0.196) and right posterior cingulate (2.405±0.236) compared with the related picture naming task (2.594±0.254, 3.626±0.560, 2.038±0.115, 1.990±0.094), and the differences were statistically significant ( P<0.05). In the phonological-related time windows, the dominant regions appeared in the unrelated picture naming task, located in left superior temporal sulcus (3.709±0.274), left superior temporal gyrus (3.901±0.380), left middle temporal gyrus (3.340±0.380), left transverse temporal gyrus (4.449±0.265), left supramarginal gyrus (3.205±0.308), left insula (3.140±0.204), left anterior cingulate (2.217±0.194) and right anterior cingulate (2.341±0.167) compared with the related picture naming task (2.662±0.300, 2.503±0.342, 2.614±0.324, 2.633±0.281, 2.663±0.278, 2.248±0.284, 1.818±0.315, 2.005±0.437), and the differences were statistically significant ( P<0.05). Conclusion:In different time windows, semantic similarities can lead to differences in brain activation.The related picture naming task can cause the dominant activation of bilateral prefrontal lobe in the visual processing stage, which may be related to sustained attention and category judgment while the unrelated picture naming task can cause dominant activation of the left temporal gyrus, left insula and bilateral limbic system during speech processing, which corresponds to semantic coding and phonology introspection.

ABSTRACT

Approximately a third of stroke patients have aphasia.As the most common clinical manifestation of aphasia patients, speech communication difficulties will lead to emotional disorders, reduce communication participation and even reduce quality of life. Distinct from dementia patients, aphasia patients after stroke are still able to discriminate and recognize the acquired semantic knowledge but cannot extract randomly and name correctly compared with healthy people. It has been proved that semantic treatment can maintain a longer duration of efficacy than phonological treatment in speech therapy. Semantic feature analysis therapy has been widely used in clinical practice and achieved good behavioral therapeutic effects. However it remains unknown whether the impaired brain function will be restored. To explore the semantic processing of human brain, it is necessary to identify " what" category of semantic features have been activated, " where" the activation center and related activities can be seen, " when" generates activities and affect " how" processing by describing the time sequence. In order to explore the neuroimaging therapeutic effects of training materials with specific semantic features, the paper reviews the influence of semantic features in spatial, temporal and frequency relationships on the brain functional activity, and prospect the future research and clinical application.

ABSTRACT

Objective To observe the features of spontaneous swallowing sounds of both the young and the elderly.Methods One hundred healthy individuals were randomly divided into an elderly group (60-85 years old) and a youth group (19-30 years old),each of 50 (25 male and female individuals).Both groups were measured with regard to their neck circumference (neck circumference around the thyroid cartilage level) and body mass index (BMI).Spontaneous swallowing sounds were detected for 20 minutes on the thyroid cartilage below the left side of trachea.By using RavenProl.5.0,the swallowing sounds were segmented,tagged and calculated in terms of the spontaneous swallowing frequency per minute (SPM),swallowing duration,energy consumption,duration of half energy consumption and proportion of half energy consumption duration.All data were finally analyzed using R3.4.0.Results There was no significant difference in the average neck circumference between the youth group and the elderly group [(34.31±3.45) cm versus (33.95±3.00)cm] (P=0.5789).The BMI of the youth group was significantly lower than that of the elderly group [(21.97±2.65)kg/m2 vs (23.43±2.89)kg/m2].The SPM of the elderly group was significantly lower than that of the youth group [(0.39±0.34) /min vs (0.91±0.51)/min,P<0.0001].The length of swallowing,the energy consumption per swallowing and the duration of half energy consumption of the elderly group (0.92±0.29 seconds,76.88 ± 9.82 dB and 0.43 ± 0.24 seconds) were significantly higher than those of the youth group (0.84±0.26 seconds,75.43±8.93 dB and 0.38±0.19 seconds).However,no significant differences were found in the proportion of half energy consumption duration in the whole swallowing sound duration (P=0.6859).Conclusions Compared with the young,the frequency of spontaneous swallowing decreased and the swallowing duration prolonged significantly in the elderly.

ABSTRACT

Objective To compare the effect of occupy effects of tumor in situ before surgery(OETS) and after neurosurgery (ANS) on neuroendocrine dysfunction and grading of neuroendocrine function in children with craniopharyngioma. Methods The grading evaluation criteria of neuroendocrine dysfunction in children with craniopharyngioma were drew up according to references and the endocrine feedback principle. Based on these grading evaluation criteria, the clinical date of 227 cases of children with craniopharyngioma who underwent neurosurgical treatment were retrospectively studied. These children were divided into pre-pubertal group (167 cases) and pubertal group (60 cases). The neuroendocrine impairment status before and after the surgery were evaluated separately. Results Among 227 children with craniopharyngioma, after the surgery, the incidence of the hypothalamus-pituitary-thyroid dysfunction increased from 16.74%(38/227) to 67.40%(153/227), the incidence of the hypothalamus-pituitary-adrenal gland dysfunction increased from 14.54%(33/227) to 44.49%(101/227), and the the incidence of pituitary function impairment increased from 17.62%(40/227) to 21.15%(48/227). Meanwhile, the incidence of body temperature dysregulation, sleeping disorder, personality abnormality and cognitive abnormality all increased after the surgery. The scoring and grading on neuroendocrine dysfunction in pre-pubertal group were increased after the surgery (Z=-5.20, P<0.01; Z=-4.94, P<0.01,). The scoring and grading on neuroendocrine dysfunction in pubertal group were increased after the surgery( Z=-4.10, P<0.01;Z=-4.25, P<0.01). Conclusions Both the mass effect of tumor in situ of craniopharyngioma and the neurosurgical treatment can be harmful to the neuroendocrine function. Even though the surgery can remove the mass effect of tumor in situ in the saddle area, it can increase the level of grading of neuroendocrine dysfunction. The status of neuroendocrine dysfunction can be evaluated by the grading evaluation criteria of neuroendocrine dysfunction in children with craniopharyngioma, which then provides an effective evaluation tool for the reconstruction and rehabilitation of neuroendocrine function.

ABSTRACT

Objective To observe the clinical efficacy of warm needling in treating neck-back myofasical pain syndrome. Method Sixty patients with neck-back myofasical pain syndrome were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by warm needling therapy, while the control group was by electroacupuncture. The short-form McGill Pain Questionnaire (SF-MPQ) and Physion MD muscle resistance detector (Japan) were adopted to measure the count of tender points (red points and yellow points), Pain Rating Index (PRI), Visual Analogue Scale (VAS), and Present Pain Intensity (PPI) before and after the treatment, and the clinical efficacies were also compared.Result The total effective rate was 83.3% in the treatment group versus 66.7% in the control group, and the difference was statistically significant (P<0.05). The SF-MPQ scores (PRI, VAS, and PPI scores) were significantly changed in the treatment group after the intervention (P<0.05). In the control group, VAS and PPI scores were significantly changed after the treatment (P<0.05). After treatment, there were significant differences in comparing the SF-MPQ scores between the two groups (P<0.05). The counts of red and yellow tender points were significantly changed in the treatment group after the intervention (P<0.05). The count of red tender points was significantly changed in the control group after the intervention (P<0.05). After the treatment, there were significant differences in comparing the number of red and yellow tender points between the two groups (P<0.05).Conclusion Warm needling is an effective approach in treating neck-back myofascial pain syndrome.

ABSTRACT

Objective To explore the effects of lifestyle intervention on index of early artery diseases in nondiabetic patients with metabolic syndrome (MS). Methods Eighty-seven nondiabetic patients with MS were randomly assigned to the intervention group ( n =47) and the control group ( n =40).The patients in the intervention group received health education,diet control,regular physical exercises,and unhealthy habit correction; however,the control group did not receive any intervention.All the patients were followed up for 9 months.Body mass index (BMI),waist circumference (WC),systolic blood pressure (SBP),diastolic blood pressure (DBP),triglyceride (TG),total cholesterol (TC),high-density lipoprotein cholesterol ( HDL-C ),low-density lipoprotein cholesterol ( LDL-C ),fasting blood glucose (FBG),HbAlc,fasting insulin (FINS),HOMA-IR,high sensitivity C-reactive protein (hs-CRP),carotid intima-media thickness (IMT),brachial-ankle pulse wave velocity (baPWV) and ankle-brachial index(ABI) were measured at baseline and at 9 months.ResultsAfter 6 or 9 months' intervention,BMI,WC,SBP,TG,HDL-C,FPG,HbAlc,FINS,HOMA-IR and hs-CRP of the intervention group were improved (all P < 0.05). HDL-C,FPG,HbAlc,FINS,HOMA-IR and hs-CRP of the intervention group were further improved at 9 months when compared to 6 months ( all P < 0.05 ). In comparison with the control group,BMI,WC,HDL-C,FPG,HbA1 c,FINS,HOMA-IR and hs-CRP were significantly improved in the intervention group at 9 months ( all P < 0.05 ).After 6 or 9 months' intervention,baPWV and ABI were significantly changed ( both P < 0.05 ) in the intervention group although IMT of the carotid did not changed (P >0.05). BaPWV and ABI were significantly changed in the intervention group when compared with those in the control group at 9 months ( both P < 0.05).The abnormal rate of baPWV in the intervention group at 9 months was 44.68%. BaPWV and ABI were associated with hs-CRP and HOMA-IR.ConclusionsIn nondiabetic MS patients, health management could significantly improve insulin resistance,modify metabolic disorders,and prevent the development of atherosclerosis.

ABSTRACT

@#Objective To investigate the expressions of Transforming Growth Factorβ2 (TGF-β2) and Smad3 in human gliomas associated with pathologic grading. Methods The expressions of TGFβ2 and Smad3 protein were detected with SP immunhistochemistry in 80 human glioma specimens. The Kapan-Meier survival curves of progression-free survival time and overall survival time in different expression levels was compared with log-rank. Results The expression of TGFβ2 and Smad3 correlated with the pathological grading (r=0.545, r=0.570, P<0.01). Both progression-free survival time and overall survival time were significantly different between low expression group and high expression group (P<0.05). Conclusion Both TGF-β2 and Smad3 correlate well with the occurrence and differentiation of human gliomas,which help for the diagnosis, treatment and prognosis judgment.

ABSTRACT

Objective To explore the effects of rhythmic auditory stimulation on the gait of patients with Parkinson's disease(PD). Methods Eight patients with PD and six healthy control subjects were studied.All subjects walked as usaal for 2 min and then Walked for 2 rain with rhythmic auditory attentional stimulation with a frequency 10% faster than their basic pace.The gait parameters in the two walking conditions were measured with three-dimension motion analysis equipment.In addition,executive function was evaluated using a frontal assessment battery (FAB)scale and the Stroop-3 test. Results In both walking conditions,average stride length and velocity were significantly lower in the PD patients than among the controls.The metronome at the higher frequency increased the cadence and stride velocity significantly in the controls.but in the PD patients it was associated with increased ca dence but decreased stride length.With auditory stimulation,the variability of velocity decreased significantly in the controls,but the variability in stride length increased significantly in the PD patients.Even with the auditory stimulation,the variability in step length,stride length and velocity were still significantly higher in the PD patients than among the controls.Executive dysfunction was clearly evident in the PD patients.Stroop-3 error rates were significantly negatively correlated with step length in the condition involving auditory stimulation.Conclusion Auditory attentional stimulation at a higher frequency becomes a new cognitive load for PD patients,and it cannot improve their gait.This may be related to executive dysfunction.

ABSTRACT

Objective To explore the generalization effect of a semantic navigation strategy(SNS)on naming in patients with aphasia.Methods Fourteen patients with aphasia were randomly divided into an SNS group (n =7)and an unrelated semantic(US)group(n =7).One hundred and twenty-two words chosen from Chinese word association norms were used in this study.The presentation sequence of words was generated automatically with network analysis techniques for the SNS group and randomly without network analysis techniques for the US group.After baseline tests using the western aphasia battery(WAB)and the mini-mental status examination(MMSE),all patients received language training once a day for 10 consecutive days.The amount of correct responses was recorded every day in order to draw the learning curve.The generalization effect was evaluated with 46 untrained items before and after training with all patients.Results The average learning curve of the SNS group was steeper than that of the US group.Correct responses on trained items were significantly more frequent in the SNS group than in the US group after the 6th day of training.After 10 days the frequency of correct responses on untrained items in the SNS group was significantly higher than it had been before training,and higher than the frequency after training in the US group.The frequency of no response on untrained items in the SNS group had declined,and it had declined more than in the US group.Conclusion A semantic navigation strategy may promote significant generalization while improving the learning curve in naming among patients with aphasia.

ABSTRACT

Objective To explore the effects of exercise on the levels of neurotrophin-3 (NT-3) in the skeletal muscles of streptozotocin-induced diabetic rats. Methods The rats were divided into an 8-week exercise group (A), a 4-week exercise group (B), a diabetes control group (C), an exercise group (D) in which no dia-betes was induced, and a control group (E). The rat model of diabetes was induced in the rats of groups A, B and C by intra-abdominal injection of streptozotocin (STZ) at 55 mg/kg. The exercising rats were forced to swim for 60 minutes once daily, 5 days a week. The levels of NT-3 in skeletal muscles were measured with an enzyme-linked immunosorbent assay. Cadual nerve conduction velocity (CNCV) in all of the rats was evaluated at the beginning, and after 4 and 8 weeks of swimming exercise. Results NT-3 levels in the skeletal muscles in group C were sig-nificantly lower than in groups A, D and E. There was no statistically significant difference in NT-3 levels between groups B and C. The NT-3 levels showed a significant positive correlation with CNCV at the 8th week. Conclu-sions The increase in NT-3 levels of skeletal muscles induced by exercise could contribute partially to the im-provement of diabetic neuropathy.

ABSTRACT

Objective To study the effects of isotonic and resistance exercises on renal hormones in plasma. Methods Eight healthy men were instructed to performed isotonic and resistance exercises, respectively, with the same target heart rate and the same exercise duration, in which both exercises-induced changes of plasma renin activity (PRA), aldosterone (ALDO) and antidiuretic hormone (ADH) were observed. Results Plasma levels of PRA, ALDO and ADH increased significantly after both isotonic exercise and resistance exercises. Plasma levels of ADH and PRA were higher after resistance exercise than those after isotonic exercise. Conclusion The increases of PRA, ALDO and ADH in plasma caused by exercise might be an adaptive response to maintain balances of water and electrolyte in the status of physical stresses. The tendency of increase of ADH and PRA after resistance exercise suggested that the exercise intensity rather than type of exercise correlated with on the changes of renal hormones.
