The red doctor spirit is a precious spiritual wealth formed in the great practice of the Chinese Communist Party leading the Chinese revolution and creating and developing people’s health undertakings. It is also an important cultural resource for nurturing medical students’ professional identity. The red doctor spirit provides cognitive resources and spiritual guidance for the formation of medical students’ professional identity, prompting medical students to form emotional identity, value identity, and behavioral identity with the profession of doctor, there by enabling medical students to more clearly understand their own missions and development goals, enhance their confidence in engaging in medical and health work, and strengthen their beliefs in working hard for the construction of a healthy China. In practice, to further enhance the leading power of the red doctor spirit in the formation of medical students’ professional identity, it is essential to deepen classroom teaching of the red doctor spirit to provide theoretical guidance; to strengthen the clinical practice of the red doctor spirit to provide practical guidance; and to foster a campus cultural atmosphere infused with the red doctor spirit , enabling medical students to naturally develop a sense of identification with the medical profession through immersive cultural influence.

This study used the natural flavonoid compound silybin as the parent compound and synthesized 16 silybin derivatives through oxidative dehydrogenation, alkylation, selective demethylation, and acylation. The structures of these derivatives were confirmed by 1H NMR, 13C NMR, and MS. All derivatives were found to be new compounds never reported in previous literature. Using gastric cancer cell line SGC-7901 and human glioblastoma cell line LN-229, the in vitro anti-tumor activity of the novel silybin derivative was determined through MTT assay with lapatinib as the positive control. The experimental results indicate that the synthesized novel silybin derivatives have a certain degree of anti-proliferative effect on two types of cancer cells, with compounds I2 and I14 showing strong anti-proliferative activity against LN-229 and SGC-7901 cells.

Objective To evaluate the influence of the wearing position of dosimeters outside lead aprons on effective dose estimation for interventional radiology workers, analyze the differences between single and double dosimeter methods in effective dose estimation, and provide a reference for the personal dose monitoring of interventional radiology workers. Methods This study employed a combined approach of on-site monitoring and Monte Carlo simulation to evaluate the impact of the wearing position of dosimeters outside lead aprons on effective dose estimation, as well as the differences between effective doses measured using single and double dosimeters. Interventional radiology workers wore dosimeters at three positions: the neck outside the lead collar, the left chest outside the lead apron, and inside the lead apron. Effective doses were estimated using the single and double dosimeter methods specified in GBZ 128-2019 Specifications for individual monitoring of occupational external exposure, and the impact of different wearing positions on the estimation results was compared. Geant4 Monte Carlo simulations were used to model dose distributions at the neck outside the lead collar and at the left chest outside the lead apron for operators performing cardiovascular interventions under tube voltages of 70, 80, 90, and 100 kVp and exposure angles of posteroanterior (PA), anteroposterior (AP), and left anterior oblique 45° (LAO45°) positions. The study assessed the impact of dosimeter wearing position on effective dose estimation. Results Monte Carlo simulations demonstrated that neck doses consistently exceeded left chest doses across different tube voltages and exposure angles, with neck-to-chest dose ratios of 0.80-0.90. Under identical tube voltage conditions, AP showed the highest doses, followed by LAO45°, and PA demonstrated the lowest doses. The single and double dosimeter methods exhibited consistent patterns in effective dose estimation. Single dosimeter method generally yielded higher effective doses with relative deviations of 9.9% to 83%, though these deviations decreased under high tube voltages. Field monitoring data indicated that most interventional radiology workers maintained relative deviations between single and double dosimeter calculations below 6%, with neck-to-chest dose ratios of 0.95-1.1. The estimation patterns remained consistent across both methods, though single dosimeter method showed slightly higher results. Conclusion Under PA, AP, or LAO45°, the doses at the neck consistently exceeded those at the left chest. Therefore, when wearing lead protective equipment, the dosimeter should be properly positioned at the neck outside the lead collar to accurately reflect the radiation doses of surgeons. Some interventional radiology workers improperly positioned the dosimeter (intended at the neck outside the lead collar) at the left chest outside the lead apron, and this may result in an underestimation of the effective dose.

OBJECTIVES:
To propose a single repetition time (TR) quantitative magnetic susceptibility imaging method for the lumbar spine using bipolar readout gradient, and compare the quantitative magnetic susceptibility measurement using single TR and dual TR methods for the lumbar spine with different bone densities.
METHODS:
A translation correction method was proposed to correct spatial misalignment along the frequency encoding direction between positive and negative gradient readout images, and the phase difference between the images was eliminated using a phase correction method. The data of lumbar vertebrae L1-L5 were collected using single TR and dual TR methods from 6 normal individuals, 2 patients with osteopenia, and 2 patients with osteoporosis. The magnetic susceptibility map was reconstructed, the quantitative results of single TR before and after correction were compared with those of the dual TR method.
RESULTS:
The linear regression result of the lumbar spine magnetic susceptibility values obtained by the single TR method before calibration and the dual TR method is Y=0.64*X-11.61. The linear regression result of the lumbar spine magnetic susceptibility values corrected by the single TR method and the dual TR method is Y=1.03*X+0.25. The results of the corrected single TR method were highly consistent with those of the dual TR method, and the calibrated single TR method could effectively distinguish osteopenia and osteoporosis patients from normal individuals.
CONCLUSIONS
The calibrated single TR bipolar readout gradient method can generate artifact-free lumbar spine quantitative magnetic susceptibility distribution maps and reduce data acquisition time by 50%.

OBJECTIVE:
To compare the efficacy and safety of intravenous colistin sulfate combined with nebulized inhalation versus intravenous monotherapy for pulmonary infections caused by carbapenem-resistant organism (CRO).
METHODS:
A multicenter retrospective cohort study was conducted. Clinical data were collected from patients admitted to the intensive care unit (ICU) of 10 tertiary class-A hospitals in Henan Province between July 2021 and May 2023, who received colistin sulfate for CRO pulmonary infections. Data included baseline characteristics, inflammatory markers [white blood cell count (WBC), neutrophil count (NEU), procalcitonin (PCT), C-reactive protein (CRP)], renal function indicators [serum creatinine (SCr), blood urea nitrogen (BUN)], life support measures, anti-infection regimens, clinical efficacy, microbiological clearance rate, and prognostic outcomes. Patients were divided into two groups: intravenous group (colistin sulfate monotherapy via intravenous infusion) and combination group ((intravenous infusion combined with nebulized inhalation of colistin sulfate). Changes in parameters before and after treatment were analyzed.
RESULTS:
A total of 137 patients with CRO pulmonary infections were enrolled, including 89 in the intravenous group and 48 in the combination group. Baseline characteristics, life support measures, daily colistin dose, and combination regimens (most commonly colistin sulfate plus carbapenems in both groups) showed no significant differences between two groups. The combination group exhibited higher clinical efficacy [77.1% (37/48) vs. 59.6% (52/89)] and microbiological clearance rate [60.4% (29/48) vs. 39.3% (35/89)], both P < 0.05. Pre-treatment inflammatory and renal parameters showed no significant differences between two groups. Post-treatment, the combination group showed significantly lower WBC and CRP [WBC (×109/L): 8.2±0.5 vs. 10.9±0.6, CRP (mg/L): 14.0 (5.7, 26.6) vs. 52.1 (24.4, 109.6), both P < 0.05], whereas NEU, PCT, SCr, and BUN levels showed no significant between two groups. ICU length of stay was shorter in the combination group [days: 16 (10, 25) vs. 21 (14, 29), P < 0.05], although mechanical ventilation duration and total hospitalization showed no significant differences between two groups.
CONCLUSIONS
Intravenous colistin sulfate combined with nebulized inhalation improved clinical efficacy and microbiological clearance in CRO pulmonary infections with an acceptable safety profile.

Picea mongolica, known for its remarkable tolerance to cold, drought, and salinity, is a key species for ecological restoration and urban greening in the "Three Norths" region of China. MYB transcription factors are involved in plant responses to abiotic stress and synthesis of secondary metabolites. However, studies are limited regarding the MYB transcription factors in P. mongolica and their roles in salt stress tolerance. In this study, 196 MYBs were identified based on the genome of Picea abies and the transcriptome of P. mongolica. Phylogenetic analysis classified the MYB transcription factors into seven subclasses. The R2R3-MYB subclass contained the maximum number of genes (84.77%), while the R-R and R1R2R3 subclasses each represented the smallest proportion, at about 0.51%. The MYB transcription factors within the same subclass were highly conserved, exhibiting similar motifs and gene structures. Experiments with varying salt stress gradients revealed that P. mongolica could tolerate the salt concentration up to 1 000 mmol/L. From the transcriptome data of P. mongolica exposed to salt stress (1 000 mmol/L) for 0, 3, 6, 12, and 24 h, a total of 34 differentially expressed MYBs were identified, which suggested that these MYBs played a key role in regulating the response to salt stress. The proteins encoded by these differentially expressed genes varied in length from 89 aa to 731 aa, with molecular weights ranging from 10.19 kDa to 79.73 kDa, isoelectric points between 4.80 and 9.91, and instability coefficients from 41.20 to 70.99. Subcellular localization analysis indicated that most proteins were localized in the nucleus, while three were found in the chloroplasts. Twelve MYBs were selected for quantitative real-time PCR (qRT-PCR), which showed that their expression patterns were consistent with the RNA-seq data. This study provides valuable data for further investigation into the functions and mechanisms of MYB family members in response to salt stress in P. mongolica.

OBJECTIVE To observe the efficacy and safety of amphotericin B combined with posaconazole in the treatment of patients with AIDS combined with cryptococcal meningitis (CM). METHODS The data of 44 patients with AIDS combined with CM admitted to Chongqing Public Health Medical Center and the First Affiliated Hospital of Army Military Medical University from January 2021 to June 2023 were collected retrospectively. They were divided into amphotericin B combined with flucytosine (AmB+FC) group and amphotericin B combined with posaconazole (AmB+POS) group according to treatment regimen, with 22 cases in each group. AmB+FC group was given Amphotericin B for injection+Flucytosine injection; AmB+POS group was given Amphotericin B for injection+posaconazole injection. After 12 weeks of treatment, clinical efficacies of two groups, clinical symptoms and the negative coversion rate of cerebrospinal fluid, and laboratory test results before and after treatment were observed in 2 groups, and the occurrence of adverse drug reactions was recorded in 2 groups. RESULTS After 12 weeks of treatment, the total effective rate, the incidences of fever, blurred vision, leukopenia, anemia, renal function abnormalities, hypokalemia, liver function abnormalities, rash, and peripheral neuropathy were compared between the two groups, and the differences were not statistically significant (P>0.05). The negative coversion rate of cerebrospinal fluid in AmB+POS group was significantly higher than AmB+FC group; the incidences of headache, nausea and vomiting symptoms, and the incidence of any adverse events were significantly lower than AmB+FC group (P<0.05). The cerebrospinal fluid pressure and cerebrospinal fluid protein content of the two groups were significantly lower than those before treatment, and the cerebrospinal fluid glucose content and cerebrospinal fluid chloride content were significantly higher than those before treatment (P<0.05); however, the differences were not statistically significant between 2 groups (P>0.05). CONCL USIONS Amphotericin B combined with posaconazole improves the negative coversion rate of cerebrospinal fluid and relieves clinical symptoms in patients with AIDS combined with CM with good safety.

Objective To explore the possible mechanism of emodin in inhibiting proliferation,migration,and invasion of AGS cells and in suppressing the expressions of YAP1 and FOXD1.Methods Normal gastric cell GES-1 and gastric cancer cell AGS were cultured with different concentrations of emodin.CCK8 test,scratch test and Transwell assay were used to verify changes in the biological phenotype of AGS cells.TCGA database was applied to analyze expressions of HK2,YAP1 and FOXD1 in gastric cancer tissues and normal gastric tissues.Western blotting method was used to detect the impacts of emodin on HK2,YAP1 and FOXD1 proteins in AGS cells.Exogenous pyruvic acid was added to verify the changes in YAP1 and FOXD1.Results The IC50 of emodin was significantly higher in GES-1 cells than in AGS cells(P<0.05).CCK8 proliferation test,scratch test,and Transwell assay showed that emodin significantly inhibited the biological abilities of AGS(P<0.05 for comparisons).Analysis on the TCGA bioinformatics database found that the expression of key enzymes HK2 in the glycolysis pathway and oncogenes YAP1 and FOXD1 was significantly higher in gastric cancer tissues than in normal gastric tissues(P<0.05 for comparisons).Emodin significantly inhibited the protein expressions of key glycolytic enzymes HK2 and oncogenes YAP1 and FOXD1(P<0.05 for comparisons).With supplement of exogenous glycolytic metabolite pyruvate,the protein expressions of oncogenes YAP1 and FOXD1 significantly increased(P<0.05 for comparisons).Conclusions Emodin has a significant pharmacological inhibitory effect on gastric cancer AGS cells,markedly suppressing their biological phenotype.Emodin not only significantly inhibits the key enzyme HK2 in glycolysis metabolism,but also the protein expressions of oncogenes YAP1 and FOXD1.With the addition of exogenous pyruvate to enhance the glycolytic metabolic pathway,the protein expressions of oncogenes YAP1 and FOXD1 significantly increased.The above results suggest a close association of YAP1 and FOXD1 with glycolytic metabolism.Emodin may inhibit oncogenes YAP1 and FOXD1 through the glycolytic metabolism of gastric cancer AGS cells.

Objective To investigate the predictive value of lactate/albumin ratio(LAR),interleukin-6(IL-6)and CD4+T lymphocyte count in 28-day mortality in patients with severe pneumonia and sepsis.Methods A total of 73 patients with severe pneumonia and sepsis admitted to the Respiratory Intensive Care Unit(RICU)of Zhengzhou Central Hospital Affiliated to Zhengzhou University from January 2022 to June 2023 were enrolled and divided into the survival group(n=43)and the death group(n=30)according to their 28-day outcomes.The clinical data of the patients were collected from their electronic medical records,including age,gender,comorbidities with hypertension,diabetes,and coronary artery heart disease(CHD),as well as sequential organ failure assessment(SOFA)score,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score,mean arterial pressure(MAP),confusion,uremia,respiratory rate,blood pressure,age ≥65 years(CURB-65)score,total bilirubin(Tbil),serum creatinine(Scr),platelet count(PLT),white blood cell(WBC)count,procalcitonin(PCT),and C-reactive protein(CRP)at admission to RICU.On the 1st,3rd,and 7th day after admission to RICU,the patients'arterial blood was drawn,and the lactate level was detected by a fully automated blood gas analyzer.The peripheral venous blood was drawn,and the serum albumin and IL-6 levels were detected by enzyme-linked immunosorbent assay,and the CD4+T lymphocyte subset count was measured by flow cytometry.The LAR of patients on the 1st,3rd and 7th day was calculated.The clinical data of the patients and the LAR,IL-6 level and CD4+T lymphocyte count on the 1st,3rd,and 7th day were compared between the two groups.The influencing factors of 28-day mortality in patients with severe pneumonia and sepsis were analyzed by logistic regression,and the predictive value of each influencing factor on the 28-day mortality in patients with severe pneumonia and sepsis was evaluated by the receiver operating characteristic(ROC)curve.Results There was no significant difference in gender,age,proportions of comorbidities with hypertension,diabetes and CHD,length of stay in RICU,and Tbil,MAP,PLT,Scr,WBC,PCT and CRP at admission to RICU(P>0.05).The APACHE Ⅱ and CURB-65 scores of the patients in the death group were significantly higher than those in the survival group(P<0.05).On the 1st,3rd and 7th day,the CD4+T lymphocyte count in the death group was significantly lower than that in the survival group,while the SOFA score was significantly higher than that in the survival group(P<0.05).On the first day,there was no significant difference in the LAR and IL-6 level be-tween the death group and the survival group(P>0.05).However,on the 3rd and 7th day,the LAR and IL-6 level in the death group were significantly higher than those in the survival group(P<0.05).The LAR,IL-6 level and SOFA score on the 3rd and 7th day in the survival group were significantly lower than those on the 1st day,and these indicators on the 7th day were sig-nificantly lower than those on the 3rd day(P<0.05);the CD4+T lymphocyte count on the 3rd and 7th day was significantly higher than that on the 1st day(P<0.05),while it showed no significant difference on the 7th and 3r day(P>0.05).The IL-6 level on the 7th day in the death group was significantly lower than that on the 1st and 3rd day(P<0.05),while there was no significant difference in IL-6 level on the 1st day compared with the 3r day(P>0.05);moreover,there was no significant difference in LAR,CD4+T lymphocyte count and SOFA score between each time point(P>0.05).Pearson correlation analy-sis showed that on the 3rd day,the LAR and IL-6 level were significantly positively correlated with the SOFA score in patients with severe pneumonia and sepsis(r=0.385,0.394;P<0.05).On the 7th day,the LAR and IL-6 level were also significantly positively correlated with the SOFA score(r=0.418,0.402;P<0.05).On the 3 rd and 7 th day,CD4+T lymphocyte count was significantly negatively correlated with the SOFA score(r=-0.451,-0.454;P<0.05).Logistic regression analysis showed that the APACHE Ⅱ score,LAR,IL-6 level and CD4+T lymphocyte count on the 3rd day,and the IL-6 level and CD4+T lym-phocyte count on the 7th day were the influencing factors for 28-day mortality in patients with severe pneumonia and sepsis(P<0.05).The ROC curve showed that the APACHE Ⅱ score,LAR,IL-6 level and CD4+T lymphocyte count on the 3rd day and the combination of the three,IL-6 level and CD4+T lymphocyte count on the 7th day and the combination of the two had certain predictive value for the 28-day mortality in patients with severe pneumonia and sepsis(P<0.05).The area under the ROC curve(AUC)of LAR,IL-6 level and CD4+T lymphocyte count on the 3rd day combined to predict 28-day mortality in patients with severe pneumonia and sepsis was 0.891,and the AUC of APACHE Ⅱ score for predicting 28-day mortality in pa-tients with severe pneumonia and sepsis was 0.769.The AUC values of LAR,IL-6 level and CD4+T lymphocyte count on the 3rd day for predicting 28-day mortality in patients with severe pneumonia and sepsis were 0.795,0.757 and 0.770,respective-ly,and the AUC values of IL-6 level and CD4+T lymphocyte count on the 7th day and their combination for predicting 28-day mortality in patients with severe pneumonia and sepsis were 0.743,0.802 and 0.888,respectively.Conclusion The 3-day LAR,IL-6 level and CD4+T lymphocyte count,and the 7-day IL-6 level and CD4+T lymphocyte count after admission are re-lated to the 28-day mortality in patients with severe pneumonia and sepsis.The combined LAR,IL-6 level and CD4+T lympho-cyte count on the 3rd day can better assess the severity and prognosis of patients.
