Objective:To investigate the application of multiscale low-rank plus sparsity (MLRS) modeling in fast ultra-high-field intracranial 4D Flow imaging.Methods:Ten healthy volunteers, 5 males and 5 females, aged 23-35 (29±4) years old, recruited from October 2022 to January 2023 at Huashan Hospital of Fudan University, were prospectively collected. A MLRS model acceleration algorithm was proposed according to the characteristics of 4D Flow data based on the multiscale low-rank (MLR) model. Firstly, full sampling brain 4D Flow scans were performed on healthy volunteers using 7.0 T MR, and the acquired data were under-sampled with Gaussian distributions at different acceleration rates (R of 4, 8, 12, and 16, respectively). The root mean square error (RMSE) and peak signal-to-noise ratio (PSNR) of the compressed sensing algorithm (CS), low-rank plus sparse algorithm (L+S), MLR, and MLRS model were calculated at different acceleration rates, with fully sampled data as reference. And the comparison of models was performed using the paired-samples t-test or Wilcoxon signed rank test. Pearson′s test was used to assess the correlation between hemodynamic parameters of the 4 algorithms and the fully sampled reference values at different acceleration rates, and the correlation coefficients were compared using Wilcoxon signed rank test. Results:The RMSE under the same acceleration rates was MLRS, MLR, L+S, and CS models in ascending order, and the RMSE of the MLRS model was significantly lower than that of the MLR, L+S, and CS models ( P<0.05); the PSNR was MLRS, MLR, L+S, and CS models in descending order, and the PSNR of the MLRS model was significantly higher than that of the MLR, L+S, and CS model ( P<0.05). The correlation coefficients between the blood flow velocity measured by the MLRS model and the reference value were significantly higher than those of the MLR, L+S, and CS models for different acceleration rates ( P<0.05). Conclusion:The proposed MLRS algorithm is capable of accelerating ultra-high-field 4D Flow MR imaging of the brain while guaranteeing the image quality, and the MLRS model has higher reconstruction accuracy compared with conventional acceleration models at the same acceleration rate.

Elucidating the active components of traditional Chinese medicine(TCM)is essential for understanding the mechanisms of TCM and promote its rational use as well as TCM-derived drug development.Recent studies have shown that surface plasmon resonance(SPR)technology is promising in this field.In the present study,we propose an SPR-based integrated strategy to screen and analyze the major active components of TCM.We used Radix Paeoniae Alba(RPA)as an example to identify the compounds that can account for its anti-inflammatory mechanism via tumor necrosis factor receptor type 1(TNF-R1).First,RPA extraction was analyzed using an SPR-based screening system,and the potential active in-gredients were collected,enriched,and identified as paeoniflorin and paeonol.Next,the affinity con-stants of paeoniflorin and paeonol were determined as 4.9 and 11.8 μM,respectively.Then,SPR-based competition assays and molecular docking were performed to show that the two compounds could compete with tumor necrosis factor-α(TNF-α)while binding to the subdomain 1 site of TNF-R1.Finally,in biological assays,the two compounds suppressed cytotoxicity and apoptosis induced by TNF-α in the L929 cell line.These findings prove that SPR technology is a useful tool for determining the active in-gredients of TCM at the molecular level and can be used in various aspects of drug development.The SPR-based integrated strategy is reliable and feasible in TCM studies and will shed light on the eluci-dation of the pharmacological mechanism of TCM and facilitate its modernization.

Objective:To construct a humanistic care intervention program for stroke patients after discharge and evaluate the implementation effect.Methods:Through preliminary research, literature review and expert consultation, the humanistic care program for stroke patients after discharge based on Watson's humanistic care theory was constructed and integrated into clinical practice intervention program and implemented. By convenience sampling method, stroke patients discharged from the Neurology Department of Shanghai Pudong New Area People's Hospital in June 2019 were selected as the control group, and patients discharged in July 2019 were selected as the intervention group. The control group received routine follow-up, and the intervention group received humanistic care intervention program after discharge. The scores of the WHO Quality of Life-BREF (WHOQOL-BREF) , limb function improvement, and the General Well-Being Schedule were compared between the two groups before and after the intervention.Results:After the intervention, the WHOQOL-BREF total score of the intervention group was (55.74±4.88) , and the total score of the General Well-Being Schedule was (72.06±8.02) , which was higher than (48.49±5.77) , (65.09±3.45) of the control group. The differences were statistically significant ( P<0.05) . After the intervention, the limb function improvement score of the intervention group was (3.52±0.71) , which was not significantly different from that in the control group (3.20±0.63) . Conclusions:Through the construction and application of humanistic care program for stroke patients after discharge, it can effectively improve the quality of life, and happiness of COPD patients.

In the perioperative nutritional management of lung transplantation patients, we should fully consider various factors, provide targeted and precision nutritional interventions, improve the nutritional practice and status of patients by improving their nutritional knowledge and attitude.

Objective? To investigate the incidence of post-stroke depression(PSD) and its risk factors, so as to provide the theoretical reference for the prevention of community PSD. Methods? A total of 300 stroke patients hospitalized in the department of neurology in the First Bethune Hospital of Jilin University from July 2016 to May 2017 were selected and assessed by Self-rating Depression Scale(SDS) and Hamilton Depression Scale(HAMD) on their depression. The incidence of PSD was analyzed and after controlling the confounding factors, the relation between PSD and relevant influencing factors were indicated by the Odds Ratio(OR) and 95% Confidence Interval (CI). Results? The incidence of PSD was 31.6% (95/300) in the 300 stroke patients. After controlling the confounding factors, it was found that marital status, occupational status, decreased activity ability, muscle strength, neurological impairment and diabetes were closely related to PSD (P＜0.05). Conclusions? The prevalence of PSD is high and closely related to marital status, occupational status, decreased activity ability, muscle strength, neurological impairment and diabetes. Understanding the risk factors of PSD is necessary to provide intervention for the prevention and treatment of PSD, which has a certain effects in reducing PSD and improving the PSD patients' physical function.
