ABSTRACT
Objective:To analyze the independent risk factors for the occurrence of post-traumatic cognitive dysfunction, construct a prediction model for the risk factors of post-traumatic cognitive dysfunction, and verify the effectiveness of the risk prediction model, so as to provide a clinical tool for early prediction of the risk of post-traumatic cognitive impairment.Methods:Part I: patients with brain trauma (training set with 556 subjects) who were hospitalized in 21 tertiary and secondary hospitals from Tangshan, Cangzhou and Chengde cities of Hebei province were retrospectively collected from February to May 2021 for Montreal cognitive assessment, and 33 influencing factors (general data, symptoms and signs, laboratory and imaging parameters) were obtained obtained through literature research.The patients were divided into case group and control group according to whether they had cognitive impairment or not, and univariate and multivariate analysis were used to screen independent risk factors.Part Ⅱ: a binary Logistic regression equation was used to construct a cognitive impairment prediction model, the visualization model of line graph is presented.Part Ⅲ: brain trauma patients (260 subjects of the validation set) hospitalized in the aforementioned 21 hospitals from August to October 2021 were collected as a prospective validation population for the prediction model of cognitive impairment, and the grouping basis of case group and control group was the same as before.And the risk factors between the two groups were compared.The receiver operating characteristic curve(ROC), calibration curve and clinical applicability of the model were drawn to evaluate the effectiveness of the model for internal and external verification of the model.Results:Binary Logistic regression analysis showed that the risk factors for post-traumatic cognitive dysfunction were basal ganglia injury, severe injury, amnesia experience after injury, frequent headache after injury, upper limb dysfunction after injury, age ≥ 60 years, and education level of elementary school or below.Visual nomograms showed that the experience of amnesia after injury, frequent headache after injury, upper limb dysfunction, and degree of injury among the symptom factors were the factors that contributed greatly to the risk of traumatic brain injury cognitive impairment in this model.Predictive model discrimination using area under curve(AUC) values of the area under the ROC curve showed that internal validation and external validation were 0.868 and 0.885 for R language analysis and 0.868 and 0.901 for SPSS analysis, respectively.The curve after model calibration almost coincided with the reference line, Hosmer-Lemeshow test P>0.05.The two decision curve analysis (DCA) curves drawn by the clinical applicability of the model were higher than the two extreme curves, predicting that traumatic brain injury patients with cognitive impairment could benefit from the predictive model, and there was a net benefit rate in the range of Pt about 0.1-0.8, when Pt reached about 0.1 until the approximate 1.0 composite evaluation model. Conclusion:Risk factors such as experience of amnesia after injury, frequent headache after injury, upper limb dysfunction, and degree of injury are predicting factors contributed to the risk of cognitive impairment in traumatic brain injury, and their prediction models have good predictive effect, high predictive accuracy and good clinical applicability, which can be applied in clinical diagnosis.

ABSTRACT
@#Objective To investigate the risk factors of cognitive dysfunction in patients with traumatic brain injury. Methods From March to September, 2021, 556 hospitalized patients with traumatic brain injury were selected from a multicenter study. A 1∶1 sex-matched case-control study design was used. After assessment by Montreal Cognitive Assessment (MoCA), those with cognitive impairment were as case group and those without cognitive impairment were as control group. They were collected general data and assessed with Social Support Rating Scale (SSRS) and Hospital Anxiety and Depression Scale (HADS). Results Logistic regression analysis showed that college education or above (OR = 0.040) and high level of social support (OR = 0.118) were protective factors for cognitive impairment (P < 0.05). Aged 60 to 88 years (OR = 9.996), severe brain injury (OR = 7.345), headache after injury (OR = 2.159), frequent waking at night or multiple dreams ≥ three times per week (OR = 3.705), severe upper limb dysfunction caused by brain injury (OR = 6.072), depression (OR = 5.202) were risk factors for cognitive impairment (P < 0.05). Conclusion The related factors for cognitive impairment in patients with traumatic brain injury include general factors, disease factors, sleep, psychological and social support and other factors. It is suggested that in addition to the treatment of disease, it is necessary to improve sleep, psychology and social support, to reduce the incidence of cognitive impairment and promote the recovery of disease.

ABSTRACT
Objective To investigate the changes in the expression of phosphatidylinositol 3?kinase(PI3?K),mammalian target of rapamycin (mTOR)and Beclin?1 in the hippocampus of normal rats and intermittent hypoxia rats with cerebral ischemia/reperfusion ,so as to explore the role of PI3K/mTOR/autophagy pathway in global cerebral ischemia/reperfusion injury aggravated by intermittent hypoxia. Methods A total of 80 healthy male Wistar rats were randomly divided into sham operation group(SO group,n=20),merely ischemia/reperfusion group(I/R group,n=20),intermittent hypoxia for 7?day ischemia/reperfusion group(IH7+I/R group,n=20),and intermittent hypoxia for 21?day ischemia/reperfusion group(IH21+I/R group,n=20). IH7+I/R group and IH21+I/R group were respectively given intermittent hypoxia for 7 days and 21 days before ischemia/reperfusion. The cerebral ischemia/reperfusion model was established by modified Pulsinelli four?vessel occlusion method. The morpholog?ical changes of nerve cells in hippocampal CA1 region were observed by HE staining and electron microscope. The protein expressions of PI3?K, mTOR and Beclin?1 of nerve cells in hippocampal CA1 region were detected by immunohistochemical staining and RT?PCR. The learning memory capacity of rats were assessed by the Morris water maze test. Results Compared with SO group,I/R group increased the never cells morphology damages,reduced the number of survival neurons,and declined the ability of learning and memory(P<0.05). Immunohistochemistry showed that the number of PI3?K immunoreactive cell,mTOR immunoreactive cell and Beclin?1 immunoreactive cell increased in I/R group compared with S0 group(P<0.05). RT?PCR showed that the expressions of PI3?K,mTOR and Beclin?1 increased in I/R group compared with S0 group(P<0.05). Compared with I/R group,intermittent hypoxia groups increased the never cells morphology damages,decreased the number of survival neu?rons,and declined the ability of learning and memory(P<0.05). Immunohistochemistry showed that the number of PI3?K immunoreactive cell, mTOR immunoreactive cell and Beclin?1 immunoreactive cell increased in IH7+I/R and IH21+I/R groups compared with I/R group(P<0.05). RT?PCR showed that the expressions of PI3?K,mTOR and Beclin?1 increased in IH7+I/R and IH21+I/R groups compared with I/R group(P<0.05),and the changes were more significant in IH21+I/R group(P<0.05). Conclusion Intermittent hypoxia can aggravate neurological injury after ischemia,which is related to PI3K/mTOR/autophagy pathway activation.

Objective To understand the anxiety among gerontal patients with osteoporosis,and to analyze the correlated factors of the anxiety.Methods The social information of the gerontal patients with osteoporosis were investigated,as well as by SAS for the anxiety,and by NRS,PSQI,AHSMSRS for their pain level,sleep quality and healthy management.Results The incidence rate of anxiety was 20.3%,and the average score was (41 .1 4 ± 9.71 )points.Some factors had influence upon the rate,which included sex,month income,sleep quality,self -care ability,pain level,self -management and exercise.Multivariate logistic regression analysis showed that exercise and pain level were the major risk factors.The differences were statistically significant(t =3.033,2.727,P =0.003, 0.007).Conclusion It's higher that the incidence rate of anxiety among gerontal patients with osteoporosis maybe influenced by species of factors,and the quality of life among them needs to be improved by intervention clinically implicated in those factors.
ABSTRACT
Objective To observe the intervention effect of Forbrain speech auditory feedback training on cognitive dysfunction in patients with stroke.methods 120 patients with cognitive dysfunction after stroke were divided into experimental group 1(n=40),experimental group 2 (n=40)and control group(n=40).The control group accepted conventional rehabilitation,while the experimental group 1 received Forbrain speech auditory feedback training additionally,and the experimental group 2 received the non-standard Forbrain speech auditory feedback training additionally.All the cases were assessed with Montreal cognitive assessment scale (MoCA)before and 10 weeks after intervention.Result sAfter 10-week intervention,the scores of structure skills(2.05±0.50),attention and concentration(2.15±0.36),memory(2.18±0.59) and the total score of MoCA(17.53±2.41) in experimental group 1 were higher than those in experimental group 2 (1.80±0.46,1.90±0.44,1.90±0.55,17.53±2.41) and control group(1.78±0.53),1.85±0.36,1.70±0.56,17.18±2.37) (all P<0.05).The Scores of language in experimental group 1(2.03±0.48)and experimental group 2(1.85±0.53) were higher than those in control group(1.70±0.46) (all P<0.05).Conclusion Forbrain speech auditory feedback training can improve cognitive function of patients with stroke.
ABSTRACT
Objective To explore the correlation between the reliability and validity of Brunel balance assessment(BBA)with the activities of daily living(ADL).Methods The BBA,ADL and walking ability test were performed on 215 patients conforming to the inclusion standard by two professionals.The Pearson correlation analysis,factor analysis and descriptive statistical analysis were adopted.Results The BBA total score and Cronbach's α coefficient in 3 dimensions was 0.852～0.941(P＜0.01),moreover the relative coefficient of each item with its dimension was higher that that of other dimensions;3 common factors were extracted by the factor analysis,the contribution rate was 83.916％;but BBA had the ceiling effect,the relative coefficient of BBA with ADL and walking ability was 0.284-0.709(P＜0.05).Conclusion BBA has a good reliability and validity and can better reflect the functions of ADL and walk.
ABSTRACT
Objective To investigate the effect of Tomatis audio training on executive dysfunction in patients with stroke. Methods A total of 80 stroke patients from the Rehabilitation Branch,Tangshan Worker′s Hospital were enrolled prospectively. They were divided into either a music group or a control group (n = 40 in each group)according to random number table. On the basis of conventional rehabilitation training,both groups received music training. The patients of the control group received conventional music training (conventional frequency music without audio processing);the patients of the music group received Tomatis audio training. Both groups were trained at the same time,once a day for 60 -90 min,and they were trained for 2 cycles. The first cycle was 14 days and the second one was 10 days,the interval of the 2 cycles was 30 days (a total of 54 days). The Behavioral Assessment of Dys-executive Syndrome (BADS)was used to assess their executive dysfunction before and after music training. Results The 6 sub-projects of BADS in the music group after music training:the rule shift cards test,action program test,key seek test, temporal judgment test,zoo map test,modified six elements test,and total standard score (median 75 ])2. 0 (1. 2,2. 7),2. 0 (1. 0,2. 0),2. 0 (1. 0,2. 0),2. 0 (1. 0,2. 0),2. 0 (2. 0,2. 0),2. 0 (2. 0,3. 0),and 11. 0 (11. 0,12. 0),respectively). They were compared with those of the control group (1. 0[1. 0,2. 0],1. 0[1. 0,2. 0],1. 0[1. 0,2. 0],1. 0[1. 0,2. 0],1. 0[1. 0,2. 0],1. 0[1. 0,1. 0],and 8. 0[8. 0,10. 0],respectively]. There were significant differences between the 2 groups (all P < 0. 05). Conclusion Tomatis audio training may effectively improve the executive function in patients with stroke.
