OBJECTIVE To analyze the characteristics of peripheral blood leukocyte morphology,scatterplot and leukocyte cell population data(CPD)in patients with severe fever and thrombocytopenia syndrome(SFTS),infec-tious mononucleosis(IM)and hemorrhagic fever with renal syndrome(HFRS),and to explore their differences.METHODS Blood routine examination data were collected,including microscopic cell images,scatter-plots and leukocyte CPD study parameters from 44 patients diagnosed with SFTS,17 with IM and 11 with HFRS at the First Affiliated Hospital with Nanjing Medical University from Mar.2023 to May 2024.These data were compared with those of healthy controls to explore specific differences in the characteristics of peripheral blood leu-kocyte.RESULTS All 3 viral infections exhibited a left shift in the nucleus under the microscope,yet the blood routine scatterplot and microscopic leukocyte characteristics differed.SFTS commonly presented with a plasmacy-toid reactive lymphocyte with scattered points appearing in the upper reactive lymphocyte area of the scatterplot.IM showed a predominant irregular fried-egg-like reactive lymphocyte under the microscope,with the scatterplot typically presenting a rocket-like shape,in patients with HFRS,there was a significant increase in im-mature granulocytes in peripheral blood and plasmacytoid reactive lymphocyte scatter points with blue immature granulocyte scatter points visible.The fluorescence distribution width(MO-WY)of monocytes in the SFTS group was lower than those in the IM,HFRS and healthy control groups(P＜0.05).Compared to SFTS,IM and healthy control groups,the lateral scattered light distribution width(NE-WX)and fluorescence distribution width(NE-WY)of neutrophils in the HFRS group were both increased(P＜0.05).CONCLUSIONS There are signifi-cant differences in the characteristics of peripheral blood leukocyte morphology,scatterplot and CPD study param-eters among three viral infection diseases SFTS,IM and HFRS.These differences can provide early clinical advice and assist in clinical differentiation.

Objective:To analyze the current status and influencing factors of national virtual simulation experimental teaching courses in medical education, and to provide a basis for optimizing resource allocation and improving the quality of education.Methods:All the medical courses on the national virtual simulation experimental teaching platform "Experimental Space" as of January 15, 2025 were included in the study. Python was used to collect data such as the year of course launch, discipline, experimental type, and access performance. Moreover, a descriptive analysis was carried out. STATA 17 was used for stepwise ordinary least square (OLS) regression to explore the influencing factors of the number of experimental participants and the pass rate.Results:The mean number of experimental participants for 659 courses was 1 020.91, and the mean pass rate was 51.71%. The results of stepwise OLS regression analysis showed that access response time, year of course launch, major, and experimental type were influencing factors of the number of experimental participants, while the first three were influencing factors for the experiment pass rate, with significant differences ( P<0.05). Conclusions:The national virtual simulation experimental teaching platform should streamline management, adopt normalized and innovative mechanisms to optimize technical performance, enhance discipline structure for balanced resource allocation, and implement dynamic evaluation to prioritize quality sharing, thus shifting the digital transformation of medical education from scale expansion to quality sharing.

Objective:To explore the efficacy of intensive repetitive transcranial magnetic stimulation (irTMS) in treatment-resistant depression (TRD) and its impact on cognitive function and systemic immune-inflammation index (SII).Methods:Forty-eight TRD patients were divided into observation group and control group using random number table method, with 24 patients in each group. The observation group was treated with irTMS, and the stimulation site was the left dorsolateral prefrontal lobe. The stimulation intensity was 110% of the motor threshold, and the stimulation frequency was 15 Hz. The stimulation interval was 26 s, and 3 000 pulses were stimulated each time. Stimulating 5 times per day, with an interval of 50 min, and continuous treatment for 5 days. The total stimulation amount for 5 days was 75 000 pulses. The control group was treated with pseudo stimulation. Before treatment (T0), 5 days after treatment (T1), and 1 month after treatment (T2), 17-item Hamilton depression scale (HAMD-17) was used to assess depressive mood. Evaluating cognitive function using the Wisconsin card sorting test.A fully automated blood cell analyzer was used to detect platelet count (PLT), neutrophil count (NC), and lymphocyte count (LC), calculate the systemic immune inflammation index (SII), SII=PLT × NC/LC. Statistical analysis was conducted using SPSS 20.0 software. The comparison between two sets of repeated measurement data was performed using repeated measurement analysis of variance.Simple effect analysis was performed if the interaction effect was significant.Pearson analysis was used for correlation testing.Results:The interaction effect between the time and group of HAMD-17 scores was significant ( F=121.784, P<0.05). The results of simple effects analysis showed that the HAMD-17 scores of the observation group at T1 and T2 ((12.07±4.08) and (14.78±4.99), respectively) were lower than those of the control group ((23.78±5.87) and (24.67±7.00), P<0.05). The treatment response rate and remission rate of the observation group at T1 were higher than those of the control group ( χ2=4.090, 7.378, both P<0.05).The treatment response rate and remission rate of the observation group at T2 were higher than those of the control group ( χ2=4.463, 4.547, both P<0.05). The time and group interaction effects of the percentage of correct response and conceptualization level in the Wisconsin card sorting test were significant ( F=30.087, 20.004, P<0.05). The results of simple effects analysis showed that the percentage of correct response and conceptualization level in the observation group at T1 and T2 were higher than those in the control group (all P<0.05). The time and group interaction effect of SII was significant ( F=8.173, P<0.05). The results of simple effects analysis showed that there was no statistically significant difference in SII between the two groups at T0 ( P>0.05). The SII at T1 and T2 in the observation group was lower than that in the control group ( P<0.05). In the observation group, the changes in SII from T2 to T0 was positively correlated with the change in HAMD-17 scores ( r=0.527, P<0.05), and negatively correlated with the percentage of correct responses to the Wisconsin card sorting test ( r=-0.412, P<0.05) and the percentage of conceptualization level ( r=-0.411, P<0.05). Conclusion:irTMS is effective in treating TRD and can improve patients' cognitive function and immune inflammation damage.

Objective:To introduce an innovative concept teaching method called the core case analysis (CCA), to evaluate its application in teaching, and to provide a theoretical basis and practical reference for improving teaching effectiveness and cultivating practical talents.Methods:This paper elaborated the application strategies of CCA in teaching health service management courses. All the students of two undergraduate classes who studied "health service management" and enrolled in 2021 and 2020 at a medical university were selected as the research objects. The students were divided into experimental group and control group according to whether they received the CCA teaching method. A statistical analysis was performed on the scores of single-choice questions designed for concept definition and term explanation questions in the final exam. SPSS 23.0 software was used for t test. A questionnaire survey was conducted in the experimental group to comprehensively evaluate the effectiveness of teaching with the CCA method. Results:The score of the experimental group was significantly higher than that of the control group [(14.00±1.41) vs. (12.05±2.15), P=0.002]. The questionnaire showed that the teaching effectiveness of the CCA method and the students' acceptance of the method were relatively high. Conclusions:Compared with the traditional concept teaching method, the CCA method has advantages and is worthy of promotion and application in related teaching fields. Moreover, several key points of this method in teaching practice are put forward: emphasizing the combined use of multiple teaching methods, cultivating a professional teaching team, and optimizing the concept assessment and evaluation system.

Objective: To investigate the relationship between relative grip strength and hyperuricemia (HUA) levels in university freshmen, and to explore the potential value of muscle function indicators in HUA prevention among young populations, so as to provide new scientific evidences for HUA control in the demographic. Methods: Utilizing health examination data from 1 744 freshmen enrolled in a Shaanxi Province university in September 2024, absolute grip strength was measured using CAMRY electronic dynamometers, with relative grip strength subsequently calculated. Spearman correlation analysis was employed to examine relationships between student characteristics and relative grip strength, and binary Logistic regression models assessed the association strength between relative grip strength and HUA. Results: The overall HUA detection rate among freshmen was 29.8%, with significant gender differences (male:43.1%; female:24.0%; χ 2=64.62, P <0.01). Correlation analysis revealed significant associations between relative grip strength, body weight, height, body mass index (BMI) and HUA in both genders (boys: r =-0.27, 0.54, 0.11 , 0.53; girls: r =-0.18, 0.33, 0.08, 0.33, all P <0.05). Binary Logistic regression demonstrated that each standard deviation increase in relative grip strength reduced HUA risk by 77% in males ( OR=0.23, 95%CI =0.14-0.37) and 80% in females ( OR=0.20, 95%CI =0.11-0.36) (both P <0.01). Conclusions Relative grip strength represents a significant factor associated with HUA in university students. Incorporating muscle strength training into HUA prevention programs and establishing muscle function based HUA risk warning systems should be considered.
