ABSTRACT

OBJECTIVE@#To obtain the subtypes of the clinical hypertension population based on symptoms and to explore the relationship between hypertension and comorbidities.@*METHODS@#The data set was collected from the Chinese medicine (CM) electronic medical records of 33,458 hypertension inpatients in the Affiliated Hospital of Shandong University of Traditional Chinese Medicine between July 2014 and May 2017. Then, a hypertension disease comorbidity network (HDCN) was built to investigate the complicated associations between hypertension and their comorbidities. Moreover, a hypertension patient similarity network (HPSN) was constructed with patients' shared symptoms, and 7 main hypertension patient subgroups were identified from HPSN with a community detection method to exhibit the characteristics of clinical phenotypes and molecular mechanisms. In addition, the significant symptoms, diseases, CM syndromes and pathways of each main patient subgroup were obtained by enrichment analysis.@*RESULTS@#The significant symptoms and diseases of these patient subgroups were associated with different damaged target organs of hypertension. Additionally, the specific phenotypic features (symptoms, diseases, and CM syndromes) were consistent with specific molecular features (pathways) in the same patient subgroup.@*CONCLUSION@#The utility and comprehensiveness of disease classification based on community detection of patient networks using shared CM symptom phenotypes showed the importance of hypertension patient subgroups.

ABSTRACT

Objective:To explore the characteristics of local brain neural activity in post stroke aphasia (PSA) patients in different frequency bands and the relationship between Western Aphasia Battery (WAB) scores and specific frequency bands. Methods:From March, 2015 to May, 2018, 15 PSA patients, and 15 healthy adults as controls matched for age, gender and education were recruited. They were assessed with WAB and scaned with resting-state functional magnetic resonance imaging. The amplitude of low-frequency fluctuation (ALFF) and fractional amplitude of low-frequency fluctuation (fALFF) on the frequency bands of 0.01-0.08 Hz, 0.027-0.073 Hz, and 0.01-0.027 Hz were calculated. The ALFF and fALFF in different frequency bands were extracted and the correlation with the WAB scores in the patients were analyzed. Results:On 0.01-0.08 Hz, ALFF increased in the right precentral gyrus in the patients. On 0.027-0.073 Hz, ALFF increased values in the right precentral gyrus, and fALFF decreased in the right cerebellar Crus2 region; fALFF in the right cerebellar Crus2 region negatively correlated with the scores of information content (r = -0.576, P = 0.025), auditory comprehension (r = -0.658, P = 0.008), repetition (r = -0.616, P = 0.014) and aphasia quotient (r = -0.611, P = 0.016) of WAB. On 0.01-0.027 Hz, the fALFF decreased in the left inferior parietal limbic gyrus, and positively correlated with the scores of information content (r = 0.538, P = 0.039) and aphasia quotient (r = 0.526, P = 0.044). Conclusion:Resting-state fALFF abnormalities in PSA patients are frequency-dependent, which associate with some frequency-specific neurofunctional alterations.

ABSTRACT

Objective:To develop a patient-reported outcomes (PRO) scale for post-stroke aphasia based on the Traditional Chinese Medicine (TCM) holism. Methods:Referring to the TCM holism, the theoretical model was established following the standard process for the development of the PRO scale. An item pool was established and optimized with case review, patient interview, expert questionnaire survey and consensus conference. The PRO scale was established finally. Results:A pool of post-stroke aphasia items based on the holistic view of TCM was constructed in the physical, psychological and social model. The Expert Comment Form for the PRO Scale for Aphasia after Stroke was formed after sorting out the item pool. After expert surveys and meeting discussion, 40 items were finally selected to form the first version of Patient-reported Outcomes Scale for Post-stroke Aphasia-TCM. Conclusion:The first version of Patient-reported Outcomes Scale for Post-stroke Aphasia-TCM has been developed based on the TCM holism and the concept of PRO, which can be evaluated clinically.

ABSTRACT

Objective:To clarify the characteristics of electroencephalogram (EEG) power spectrum network of right hemisphere in patients with post-stroke aphasia (PSA) after left brain damaged. Methods:From December, 2018 to June, 2019, twelve PSA patients with left hemisphere injury were recruited and twelve healthy adults were matched as control group. China Rehabilitation Research Center aphasia examination (CRRCAE) was used to evaluated the linguistic function, and the EEG was collected. The functional connection characteristics of Alpha and Theta power spectrum were compared, and the correlation with language items was analyzed. Results:In PSA patients, the functional connection enhanced in Alpha and Theta frequency bands of central area, frontal, parietal and frontal-parietal joint areas, and decreased in Theta frequency bands of temporoparietal, parietal-occipital area, frontal, fronta-parietal and frontal central areas. The enhancement of alpha frequency functional connection from the right parietal occipital region to the central region was significantly correlated to the reduction of the expression ability (P < 0.05), while the weakening of theta frequency functional connection between the right parietal occipital region and the forehead and the center of the forehead was significantly correlated to the ability of speaking, reading, copying, dictation and calculation (r = -0.676~-0.717, P < 0.05). Conclusion:EEG power spectrum network can reflect the reorganization of right brain function network, and the change of right frontal parietal central network function connection may be closely related to PSA language injury and recovery.

ABSTRACT

The cognitive neuroscience researches about post-stroke aphasia provide the interpretation of all aspects of linguistics. The word-picture research paradigm can be applied to assess different types of aphasia, in various ways of stimulation modes and models. It is more helpful combining functional magenetic resonance imaging to research the mechanism of brain damage and recovery objectively. The interactive application of language task and imaging has also become a new direction in the mechanism study of aphasia.

ABSTRACT

Objective To analyze the efficacy and biomechanical properties of locking proximal femoral plate (LPFP) and proximal femoral nail anti-rotation (PFNA) for treating intertrochanteric fracture in elderly patients. Methods One hundred and six elderly patients with intertrochanteric fracture of femur were randomly divided into LPFP group (53 cases) and PFNA group (53 cases). After treatment intervention, the operation time, intraoperative bleeding volume, weight-bearing time, fracture healing time and Harris hip function score of 9 months after operation in two groups were recorded. The complications after operation in two groups were analyzed. Ten elderly fresh femoral specimens were selected to prepare the model of intertrochanteric femoral fracture in the elderly. They were randomly divided into PFNA group and LPFP group with 5 models in each group. After treatment and intervention, axial compression test, destructive load test and torsional stiffness test were conducted by mechanical testing machine, and biomechanical properties were recorded. Results The average operation time, weight-bearing time and fracture healing time in PFNA group were shorter than those in LPFP group (P<0.05), and the average intraoperative bleeding volume in PFNA group was less than that in LPFP group (P<0.05), and the average Harris score was higher than that in LPFP group (P<0.05). The total incidence of postoperative complications in PFNA group and LPFP group was 7.56% and 18.87%, respectively, indicating a significant difference between the two groups (P<0.05). After intervention treatment, the average axial compression, damage load and torsional stiffness in PFNA group were higher than those in LPFP group (P<0.05). ConclusionsPFNA caused minimal trauma for treating intertrochanteric femoral fractures in the elderly. With its good biomechanical properties, PFNA could effectively promote fracture healing and hip function recovery, and significantly reduce the incidence of hip varus, screw loosening and cutting complications.

ABSTRACT

Objective:To compare the biomechanical effects between oblique Ban-pulling manipulation and lumbar erection-rotation manipulation in sitting position in treating lumbar intervertebral disc herniation (LIDH). Methods:A three-dimensional finite element model of L3-S1 was developed to carry out a comparative study between oblique Ban-pulling manipulation and lumbar erection and rotation manipulation in sitting position. The disc protrusion was assumed to be on the rear left of L4 disc, and the manipulations were performed on the right side. The loading process was simulated by two steps. In the first step, only the compression loading was imposed, and in the second step, both the compression loading and axial rotation moment were imposed. The displacement and stress distribution in L4 disc were investigated. Results:The values of stress and displacement in the second step were lower than those in the first step in each manipulation. The stress and displacement differences between the two steps were respectively 1.79 times and 3.03 times larger in oblique Ban-pulling manipulation than those in lumbar erection-rotation manipulation in sitting position. Conclusion: Oblique Ban-pulling manipulation may result in a better biomechanical effect than lumbar erection-rotation manipulation in sitting position for LIDH.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate whether hepatitis B virus (HBV) can induce the expression of the host-encoded cytokine interleukin-32 (IL-32) and its effects on host signaling mechanisms related to HBV pathogenesis.</p><p><b>METHODS</b>A eukaryotic expression vector harboring an enhanced green fluorescent protein was constructed with HBV genomic sequences (pIRES2-HBV-EGFP) and transfected into HepG2 cells. In addition, the nuclear factor-kappa B (NF-kB) subunits, p50 and p65, were transfected respectively into HepG2 cells. In both cases, 48 hrs after transfection, IL-32 expression was determined at the mRNA and protein levels using real-time PCR and ELISA and western blot, respectively. The HepG2 cells transfected with pIRES2-HBV-EGFP were also treated with the NF-kB inhibitor SN50 at various concentrations, and the effects on IL-32 protein expression 48 hrs later were evaluated by western blot. Significance of between-group differences was assessed by the Student's t-test.</p><p><b>RESULTS</b>Transfection with pIRES2-HBV-EGFP led to significantly higher IL-23 expression than transfection with empty vector (mRNA: 2.8-fold higher and protein: 4.5-fold higher; both P less than 0.05). Transfection of p50 and p65 proteins led to significantly higher IL-32 expression (both P less than 0.05), and NF-kB activation was found to be required for HBV-induced IL-32 expression.</p><p><b>CONCLUSION</b>IL-32 expression is induced by HBV in HepG2 cells. This host-encoded cytokine, and its downstream activation of NF-kB, may be involved in the pathogenesis of HBV, especially in the subsequent liver inflammation that accompanies HBV infection.</p>

ABSTRACT

Objective Through a two-year follow up program,this study was to analyze the urinary iodine frequency of a cohort in the intervention trial,concerning different doses of salt iodization,so as to explore the selection of appropriate concentration of salt iodization.Methods A multistage cluster sampling method was used to select three townships in two countries for community intervention with different doses [ ( 15 ± 5 ) mg/kg,(25 ± 5 ) mg/kg,( 35 ± 5 ) mg/kg ] of salt iodization.Results After intervention,the median of urinary iodine was reduced among the population.The urinary iodine frequencies of (15 ± 5) mg/kg and (25 ± 5) mg/kg among groups of children were mainly concentrated in 100-200 μg/L and 200-300 μg/L paragraphs in A county.While the 300 μg/Lparagraph had an overall decline in B county,the 100 μtg/L and 200 μg/L paragraph ratio increased but the trend seemed to be slow.The 100-300 μg/L paragraph of the four treatment groups took a larger proportion and kept smooth in a more ideal state.However,the control group still maintained at above 250 μg/L level.Conclusion The iodine supplementation should be gradually implemented in Chongqing.The doses of salt iodization should be reduced from the current (35 ± 15)mg/kg to (25 ± 5) mg/kg in the economically developed areas.At the same time,we need to continuously follow the changes of the condition.
