Objective: To investigate influence of Wenxin particle on cardiac electrophysiology in rats complicated with depression after myocardial infarction (MI). Methods: A total of 50 SD rats were randomly and equally divided into normal group, MI group, depression group, MI complicated with depression group (model group) and Wenxin particle group (Wenxin particle were given to model rats by gavage, 2 g/d, 28d). Model（MI complicated with depression）rats were made by acute ligation of left coronary artery and supply chronic unpredictable mild stress in order. The influences of Wenxin particle on cardiac electrophysiological indexes, such as monophasic action potential (MAP90), left ventricular effective refractory period (ERP) and ventricular fibrillation threshold (VFT) were evaluated in Wenxin particle group. Results: (1) Compared with normal group, there were significant decrease in behavior scores (P<0.05) in model group, after four-week treatment with Wenxin particle, their behavior scores significantly increased (P<0.01); (2) Compared with normal group, there were significant increase in MAPD90 and ERP, and significant decrease in VFT in model group (P<0.05); compared with model group, there were significant decrease in MAPD90 [(89.33±7.12) ms vs. (72.29±8.37) ms] and ERP [(84.00±6.57) ms vs. (68.00±7.43) ms], and significant increase in VFT [(7±3.11)V vs. (29±5.60)V] in Wenxin particle group, P<0.05. Conclusion: Wenxin particle can improve cardiac electrical remodeling in rats complicated with depression after myocardial infarction, including decrease monophasic action potential duration and effective refractory period, and raise ventricular fibrillation threshold.

Objective:To explore the impact of stress perception on depression and the potential mediating role of resilience in medical staff.Methods:A total of 606 medical staff were recruited and investigated by self-designed questionnaire, the perceived stress scale (PSS-10), the 10-item Connor-Davidson resilience scale (CD-RISC-10), and the patient health questionnaire-9 (PHQ-9) from February to March, 2020.SPSS 26.0 software was used to execute Pearson or Spearman correlation analysis, common method biases test, and multicollinearity test.Model 4 in PROCESS 3.2 macro program and Bootstrap method were used for mediating effects analysis.Results:There was a positive correlation between stress perception score(16.93±6.65) and depression score (5.00(2.00, 9.00))( r=0.551, P<0.01), and a negative correlation between stress perception score and resilience score (27.08±8.68) ( r=-0.285, P<0.01) among 606 medical staff.There was a negative correlation between resilience score and depression score ( r=-0.474, P<0.01). Mesometric effect examination showed that resilience played a partial mediating role in the relationship between stress perception and depression, and the mediating effect accounted for 10.87% of the total effect. Conclusion:Stress perception can directly or indirectly influence depression scores, and resilience partially mediates the relationship between stress perception and depression.Depression can be reduced clinically by reducing stress perception or enhancing the resilience of medical personnel.

Objective:To analyze the characteristics and hot spots of hospital management projects funded by National Natural Science Foundation of China(NSFC), for the reference for furthering improving the modernization level of hospital management.Methods:The NSFC funded research projects in hospital management during 2010-2020 was searched. Project name, keywords, approval year, affiliation and other informations were obtained. CiteSpace was used for bibliometric analysis of these research projects, while all the data acquired were subject to descriptive analysis and frequency analysis.Results:The number of hospital management projects funded by NSFC increased from 4 in 2010(0.93 million yuan) to 32(9.94 million yuan) in 2020, totaling 192 projects and 72.76 million yuan. These numbers consisted of 90 general projects(46.9%) and 79(41.1%) youth fund projects respectively. All the funded projects were distributed in sub-disciplines under the NSFC first-level discipline of macro management and policy, namely health management and policy(154) and medical/drug management and policy(38). The hotspots of the funded projects covered performance evaluation, payment method, public health system, health economics, hierarchical diagnosis and treatment, utility theory, regional medical alliance, essential medicine system, capitation and incentive strategy, and so on.Conclusions:Recent years are witnessing a rising trend in the number and grants of NSFC projects on hospital management. More and more funds are granted to universities, especially young researchers, and a hospital management research system has been initially taken shape. Hospital management in China should take into full account of the management characteristics and the status quo of the medical and health field, focus on performance appraisal incentive mechanism, hierarchical medical system, construction of medical alliances. and patient medical experience as well. In addition, the cooperation between hospitals and universities should be strengthened in order to promote the translation of research results.

Objective:This study mainly discussed the clinical characteristics, autoimmune status and lymphocyte subsets of patients with Takayasu arteritis (TA) without hormone and immunosuppressive therapy, in order to provide guidance for immunotherapy.Methods:Using cross-sectional study, twenty-nine patients with TA admitted to the Department of Rheumatology and the Department of Vasculitis of Beijing Anzhen Hospital from January 2018 to November 2019 were selected, including 28 females and 1 male, with the middle age of 39 year. These patients met the diagnostic criteria of American Society of Rheumatology for TA, and were not treated with hormone and immunosuppressant. Clinical data of these patients were collected, and the immunological indexes and lymphocyte subsets of peripheral blood were detected simultaneously. At the same time, the immunological indexes and peripheral blood lymphocyte subsets of 21 healthy normal people were detected as control. Chi square test, independent sample t test and nonparametric test were used for analysis. Results:Among the 29 patients with TA, 28 were female, 26 were in the active stage of disease; the main manifestations of systemic symptoms were malaise (62.07%) and headache (41.38%), the main manifestations of vascular symptoms were bruits and pulse weakening (68.97%), and the most of Numano type was V type (79.31%). The absolute value of total T (CD3) lymphocytes [(1 337.14±312.46)μl vs (1 139.95±340.96)μl, t=2.120, P=0.039], the percentage [46.29%±6.55% vs 36.55%±7.42%, t=4.903, P<0.000 1] and the absolute value [(815.52±194.11)μl vs (571.44±187.55)μl, t=4.450, P<0.000 1] of helper T (CD4) lymphocytes, the ratio of CD4/CD8 [1.83 (1.41-2.30) vs 1.32 (1.03-1.39), Z=3.401, P=0.001] were higher compared with those of healthy controls, while the percentage of natural killer (NK) cells (CD56) [10.71%(6.45%-14.30%) vs 14.57%(10.87%-18.47%), Z=2.408, P=0.016] decreased.
