Objective:To construct the user personas of the patients who practice self-management home rehabilitation after lower limb bone transport by exploring their self-management experiences and needs in rehabilitation at home so as to provide targeted countermeasures for related medical staff.Methods:A purposive sampling method was employed to select the 21 patients who had undergone home rehabilitation after lower limb bone transport at Department of Orthopedic Trauma, Nanfang Hospital from September to December 2024. The cohort included 12 males and 9 females, with an age of (39.8±15.1) years. The phenomenological research method was used to conduct semi-structured interviews with this cohort. After the data from interviews were explored by the Colaizzi 7-step analysis to extract the factual labels, role dimension models were built, covering 3 dimensions: description, characteristics (basic, cognitive, behavioral, social support, and psychological adjustment characteristics) and needs.Results:All patients were interviewed. Four user personas were constructed, including self-awareness growth type (5 cases), emotional dependency-driven type (4 cases), risk-aversion procrastination type (7 cases), and management motivation-impaired type (5 cases). The patients of self-awareness growth type were 21 to 36 years old and received high school or university education, characterized by high self-efficacy, active measures to improve and maintain their state of rehabilitation, good management of negative emotions, and a low sense of stigma. The patients of emotional low-driven type were 42 to 74 years old and received their education in a primary school or junior high school, characterized by lack of independence, dependence on others for rehabilitation management, common management of negative emotions, low self-efficacy, and a strong sense of stigma. The patients of risk-aversion procrastination type were 33 to 56 years old and received their education in a junior or senior high school, characterized by a willingness to cooperate but insufficient motivation for rehabilitation management, an awareness of rehabilitation which was vulnerable to external factors, common management of negative emotions, low self-efficacy, and a strong sense of stigma. The patients of management motivation-impaired type were 51 to 61 years old, received primary school education or lower, characterized by insufficient knowledge and poor self-management behavior, constant failure to follow the prescribed rehabilitation exercises, poor management of negative emotions, low self-efficacy, and a low sense of stigma.Conclusion:The user personas we have constructed for the patients who practice self-management home rehabilitation after lower limb bone transport can help healthcare professionals with specific targeted interventions to enhance self-management efficacy to facilitate the rehabilitation process for the patients.

OBJECTIVE: To observe the effects of electroacupuncture (EA) on improving motor function and regulating microglial activation based on Notch receptor 1 (Notch1)/Hes family bHLH transcription factor 1 (Hes1) pathway in mice with Parkinson's disease (PD). METHODS: Thirty-six male C57BL/6 mice were randomly divided into a control group, a model group and an EA group, 12 mice in each group. PD model was established by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) for 7 consecutive days in the model group and the EA group. From the 1st day of modeling, EA was applied at "Baihui" (GV20) and bilateral "Shenshu" (BL23) in the EA group, with continuous wave, in frequency of 2 Hz and current of 2 mA, 15 min a time, once a day for 14 days continuously. The behavioral performance was evaluated by gait test, pole climbing test and hanging test, the number of positive cells of tyrosine hydroxylase (TH) and the co-expression positive cells of Notch1/ionized calcium binding adaptor molecule 1 (Iba-1) in the substantia nigra of midbrain was assessed by immunofluorescence, the protein expression of TH, α-synuclein (α-syn), Notch1, Hes1, Iba-1, inducible nitric oxide synthase (iNOS), Arginase-1 (ARG1), tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6 and IL-10 was detected by Western blot, the mRNA expression of Notch1 and Hes1 was detected by real-time PCR. RESULTS: Compared with the control group, in the model group, the stride frequency was accelerated (P<0.001) and the stride length was shortened (P<0.001) for the four limbs, the pole climbing test time was prolonged (P<0.01) and the grip level was reduced (P<0.01); in the substantia nigra of midbrain, the number of positive cells of TH was decreased (P<0.001), the number of co-expression positive cells of Notch1/Iba-1 was increased (P<0.001), the protein expression of α-syn, Notch1, Hes1, Iba-1, iNOS, TNF-α, IL-1βand IL-6 was increased (P<0.01, P<0.05, P<0.001), the protein expression of TH, ARG1 and IL-10 was decreased (P<0.01, P<0.001), the mRNA expression of Notch1 and Hes1 was increased (P<0.01). Compared with the model group, in the EA group, the stride frequency was decelerated (P<0.001) and the stride length was increased (P<0.05, P<0.01, P<0.001) for the four limbs, the pole climbing test time was shortened (P<0.05) and the grip level was increased (P<0.05); in the substantia nigra of midbrain, the number of positive cells of TH was increased (P<0.01), the number of co-expression positive cells of Notch1/Iba-1 was decreased (P<0.001), the protein expression of α-syn, Notch1, Hes1, Iba-1, iNOS, TNF-α, IL-6 and IL-1β was decreased (P<0.05, P<0.01), the protein expression of TH, ARG1 and IL-10 was increased (P<0.05, P<0.001, P<0.01), the mRNA expression of Notch1 and Hes1 was decreased (P<0.05). CONCLUSION EA can improve the behavioral performance and protect the dopaminergic neurons in PD mice, its mechanism may relate to the inhibition of Notch1/Hes1-mediated neuroinflammation, thus inhibiting the microglial activation.

Objective:To explore the effect of different swallowing tasks on cortex activation and functional connectivity in stroke survivors with dysphagia using functional near-infrared spectroscopy (fNIRS).Methods:Thirty stroke survivors with dysphagia performed three different swallowing tasks: swallowing action observation (SO), swallowing action execution (SE), and swallowing action imagination (SI). During each task, fNIRS was used to document the brain concentrations of oxyhemoglobin and deoxyhemoglobin. Cortex activation (β value) and brain functional connectivity were assessed.Results:Compared with the resting state, the areas activated during the SO task included the left primary sensory cortex and the right prefrontal cortex. During the SE and SI tasks the left prefrontal cortex and the left motor cortex were activated as well. Compared with hemorrhagic stroke survivors, ischemic stroke survivors showed significantly greater activation of the right primary sensory cortex, the right motor cortex, and the left primary sensory cortex during the SE task. Functional connectivity during the SO, SE and SI tasks was significantly greater than in the resting state, with the average connectivity values during the SE task significantly higher than during the SI task.Conclusions:Stroke survivors with dysphagia exhibit increased activation in the prefrontal cortex and primary sensory cortex during different swallowing tasks. Such tasks can improve their brain functional connectivity.

Objective Studies on the expression and location of zinc finger protein A20 (A20) and connective tissue growth factor (CTGF) in liver tissues of patients with chronic hepatitis B were conducted, and the relationship between them and liver fibrosis was determined by FibroScan. Methods Studies on A20 and CTGF in liver tissues of 160 patients with chronic hepatitis B were conducted in accordance with the stage of pathological fibrosis and inflammation of the liver, and quantitative immunohistochemistry test was conducted, and statistical analysis was conducted by FibroScan. Results The expressions of A20 and CTGF in liver tissues increased with the aggravation of liver pathological fibrosis and inflammation, and there were significant differences between each stage and the control group (P<0.05), and there were significant differences between adjacent groups (P<0.05). Studies have shown that FibroScan increases along with pathological fibrosis and inflammation in the liver. There are significant differences between the stage and the control group (P<0.05), and no significant differences between the adjacent groups (P>0.05). There was positive correlation between liver A20 and CTGF, r=0.796 (P<0.05). Conclusions In patients with chronic hepatitis B, A20, CTGF and FibroScan are positively correlated with the degree of liver fibrosis, and A20 and CTGF are also positively correlated with the degree of liver inflammation, which can be used as indicators to evaluate the degree of liver inflammation and fibrosis, and further guide the anti-inflammatory and anti-fibrosis treatment of patients.
