The new synergistic education model integrating the “five arts” medical talent cultivation philosophy and the red doctor spirit could form a virtuous cycle of “spiritual guidance-technological breakthrough-spiritual reshaping” in the field of military medical education. Addressing the existing challenges in the process of military medical cadets’ training， such as mission awareness， humanistic care， battlefield rescue， and emergency response， this study proposed integrating the red doctor spirit， characterized by political steadfastness， healing the wounded and rescuing the dying， selfless devotion， relentless pursuit of excellence， and seeking truth and innovation， into the training system under the guidance of the “five arts” philosophy， including establishing a foundation through Daoist arts， forging the soul with benevolence， empowering through academia， tempering through technology， and nurturing the mind through artistry. A cultivation model was constructed featuring “moral education as the priority and cultivating through soul-forging； military spirit as the root and medical professionalism as the foundation and training for warfare； mastery in medicine for battlefield success and cultivating talent through rigorous scholarship.” Furthermore， through pathways including the optimization and implementation of the curriculum system， the enhancement and innovation of practical teaching， the development and training of the faculty team， and the improvement and innovation of the evaluation system， this model assisted in achieve the goal of cultivating compound talents with “the red medicine essence plus the five arts foundation.” These talents also built their foundation on the “five arts” philosophy， forge their spirit with the red doctor spirit， and was tempered with battlefield adaptability.

Objective To investigate the changes and clinical significance of serum kynurenine(KYN)and quinolinic acid(QA)levels in elderly patients with chronic kidney disease(CKD)complicated with major ad-verse cardiovascular events(MACE).Methods A total of 156 elderly patients with CKD treated in the Fourth People's Hospital of Taizhou from February 2022 to February 2024 were selected as the CKD group,and were divided into the MACE group(n=45)and the non-MACE group(n=111)according to whether they were complicated with MACE.A total of 80 healthy people who underwent physical examination in the Fourth People's Hospital of Taizhou during the same period were selected as the control group.High perform-ance liquid chromatography-tandem mass spectrometry was used to measure the serum KYN and QA levels in each group.Multivariate Logistic regression was used to analyze the risk factors for MACE in elderly CKD pa-tients.The receiver operating characteristic curve was used to analyze the predictive value of serum KYN and QA for MACE in elderly CKD patients.Results The levels of KYN and QA in CKD group were higher than those in control group(P<0.05).The age,levels of C-reactive protein,24 h urinary protein,KYN and QA in MACE group were higher than those in non-MACE group(P<0.05).The increased levels of 24 h urinary protein,C-reactive protein,KYN and QA were risk factors for MACE in elderly CKD patients(P<0.05).The area under the curve(AUC)of combined detection of serum KYN and QA for predicting MACE in elderly CKD patients was 0.920(95%CI 0.891-0.959),which was greater than the AUC of KYN[0.836(95%CI 0.804-0.879)]and QA[0.843(95%CI 0.798-0.887)]alone,and the difference was statistically significant(Z=4.023,3.897,P<0.05).Conclusion The levels of serum KYN and QA are increased in elderly CKD pa-tients with MACE,which are related to renal function.The combination of serum KYN and QA can effectively predict the risk of MACE in elderly CKD patients.

Objective:To compare the efficacies of endovascular therapy (EVT) and standard medical therapy in acute ischemic stroke (AIS) patients aged ≥85 years, and analyze the independent influencing factors for poor prognosis of AIS patients after EVT.Methods:Sixty-nine AIS patients aged ≥85 years admitted to Department of Neurology, Xi'an Third Hospital from January 2018 to April 2024, including 40 accepted EVT and 28 accepted standard medicinal therapy, were enrolled. Modified Rankin scale (mRS) was used to evaluate the prognosis of the patients 90 days after onset. General data, prognosis and complications between the EVT group and standard medical therapy group were compared. General data, treatment processes and complications between patients with good prognosis and poor prognosis in the EVT group were compared. Multivariate Logistic regression was used to analyze the independent influencing factors for poor prognosis in AIS patients after EVT.Results:Compared with the standard medical therapy, the EVT group had significantly lower NIHSS score at discharge, greater improvement in NIHSS score (NIHSS score at admission-NIHSS score at discharge), lower mRS score 90 days after onset, higher good prognosis rate, lower mortality rate within 90 days of onset, and longer hospital stay ( P<0.05). In the EVT group, 11 patients (27.5%) had good prognosis and 29 patients (72.5%) had poor prognosis 90 days after onset. Compared with the good prognosis group, the poor prognosis group had significantly higher blood glucose level and lower Alberta Stroke Program Early CT Score (ASPECT) on admission ( P<0.05). Multivariate Logistic regression analysis showed that blood glucose on admission ( OR=2.363, 95% CI: 1.134-4.928, P=0.022) and ASPECT score on admission ( OR=0.273, 95% CI: 0.088-0.854, P=0.026) were independent influencing factors for poor prognosis in AIS patients after EVT. Conclusion:AIS patients aged ≥85 years received EVT have better prognosis compared with those accepted standard medical therapy; these patients with high glucose level and low ASPECT score on admission have poor prognosis.

Objective:To investigate the characteristic distribution of vaginal microbiota in infertile women.Methods:We collected the results of vaginal microbiological examinations from 19322 initial visit infertile women who visited the Reproductive Medicine Center of the Department of Obstetrics and Gynecology,the Second Affili-ated Hospital of Air Force Medical University from March 1,2023 to July 31,2024.The vaginal microbiota infection status of patients was compared in different age groups(＜25 years old,25-＜30 years old,30-＜35 years old,35-＜40 years old,≥40 years old)and different seasons(spring,summer,autumn,winter).Results:①Among 19322 women,6027 cases(31.19％)showed abnormal vaginal microecology.Pathogenic microorganisms were detected in 3093 cases,including 2882 cases of single vaginitis,211 cases of mixed vaginitis,3764 cases with vagi-nal cleanliness grade Ⅲ-Ⅳ,and 3965 cases with abnormal lactobacilli.Among patients with single vaginitis,1349 cases(46.81％)were diagnosed with vulvovaginal candidiasis(VVC),which was the highest proportion.Aerobic vaginitis(AV)followed with 752 cases(26.09％),and bacterial vaginosis(BV)had 671 cases(23.28％),trichomonal vaginitis(TV)with 110 cases(3.82％).Among patients with mixed vaginitis,AV+BV was the most common with 96 cases(45.49％).②The detection rates of cleanliness grade Ⅲ-Ⅳ,abnormal lactobacilli,abnor-mal microorganisms(unclear pathogen),single vaginitis(BV,VVC and TV),and mixed vaginitis showed statisti-cally significant differences across different seasons(P＜0.05).Specifically,the detection rates of cleanliness grade Ⅲ-Ⅳ and abnormal microorganisms(unclear pathogens)were significantly higher in autumn than in other seasons(P＜0.05),while the detection rate of abnormal lactobacilli was higher in spring than in other seasons(P＜0.05).③The detection rates of abnormal lactobacilli,abnormal microorganisms(unclear pathogen),single vaginitis(BV,VVC and AV),and mixed vaginitis showed significant differences among different age groups(P＜0.05).Specifically,the detection rate of abnormal microorganisms(unclear pathogen)was higher in the age group＜25 years than in other age groups(P＜0.05),while the detection rate of BV among single vaginitis cases was higher in the age group≥40 years than in other age groups(P＜0.05).Conclusions:The vaginal microecol-ogy of infertile women varies in terms of infection rates across different age groups and seasons.Patients with simple vaginitis have the highest rate of VVC,while those with mixed vaginitis have the highest proportion of AV+BV infection.

Objective:To assess the current status of geriatrics department development in public general hospitals at or above the second grade in Shandong province.Methods:A cross-sectional survey was conducted from October 27 to November 3, 2023 using a web-based electronic questionnaire to investigate the current status of geriatrics department development in all public general hospitals at or above the second grade across 16 prefecture-level cities in Shandong province.The survey included participation from medical department staff and managers of geriatric medicine departments.Results:Shandong province has 355 public general hospitals at or above the second grade, of which 337 completed the questionnaire.Among these 337 hospitals, 92.28%(311/337)have established geriatric departments, 83.09%(280/337)have set up geriatric clinics, 69.14%(233/337)have independent geriatric wards, and 71.51%(241/337)have implemented comprehensive geriatric assessments(CGA).Regarding the configuration of geriatric departments, 60.24%(203/337)of hospitals met the requirement of having at least 20 ward beds, 34.42%(116/337)met the doctor-to-bed ratio requirement of at least 0.3, and 22.26%(75/337)met the nurse-to-bed ratio requirement of at least 0.6.Only 13 hospitals met all the requirements for geriatric wards, beds, doctors, and nurses, accounting for 3.86%(13/337)of the participating hospitals.Conclusions:The establishment of geriatrics departments in second-grade or higher public general hospitals in Shandong province has surpassed the national target in China ahead of schedule.Most hospitals have established geriatric clinics and wards and have implemented CGA.However, significant challenges remain, including a shortage of ward beds and a lack of medical staff.

Objective:To explore the predictive value of very low frequency (VLF) for the efficacy of vitamin D treatment in children with postural orthostatic tachycardia syndrome (POTS).Methods:A retrospective case-control study was conducted. A total of 65 POTS children from the Department of Pediatrics of the Second Hospital of Lanzhou University from November 2023 to May 2024 were selected as the research subjects, while 102 healthy children from the same period were selected as the control group. The 25 (OH) D levels between POTS children and healthy children were compared. The frequency of eight main symptoms, including palpitations, headache, cold sweat, blurred vision, chest tightness, dizziness, fainting, and digestive discomfort in the POTS group were analyzed, the symptom scores of the orthostatic intolerance were calculated, and the parameters related to short-range heart rate variability (HRV) during the upright test, head-up tilt test (HUTT) were collected. The correlation between 25 (OH) D levels and symptom scores of orthostatic intolerance symptoms and HRV parameters in children with POTS were analyzed by Pearson correlation analysis. The total symptom scores of children with POTS were compared for 3 months before treatment and 2 months after treatment with vitamin D 800 U/d. The difference in score before and after treatment was ≥2 as responsive group, and the score difference before and after treatment was <2 as non-responsive group. The demographic characteristics including age, gender, height, weight, body mass index, as well as HRV parameters such as the standard deviation of nn intervals (SDNN), the standard deviation of the average NN intervals (SDANN), the root mean square of successive differences (rMSSD), low-frequency (LF), high-frequency (HF), very-low-frequency (VLF) were compared between the responsive group and non-responsive group. Multivariate Logistic regression was analyzed to screen independent influencing factors of vitamin D treatment efficacy for POTS. The marker molecules related to the efficacy of vitamin D treatment in children with POTS were analyzed through receiver operating characteristic (ROC) curve.Results:A total of 167 children were included in this study. There were 65 children in the POTS group, 38 males and 27 females, with the age of (10.6±2.2) years. There were 102 healthy children in the control group, 53 males and 49 females, with the age of (11.2±1.8) years.There was no statistically significant difference in gender and age between the two groups (both P>0.05). The serum 25 (OH) D level in children in the POTS group was (37±18)nmol/L, lower than that in the control group (61±17)nmol/L ( P<0.05).Pearson correlation analysis showed that serum 25(OH)D was positively correlated with VLF, SDNN and HF ( r=0.43, 0.65, 0.36, respectively, all P<0.05). Among the POTS children, there were 48 cases in responsive group and 17 cases in non-responsive group. Univariate analysis revealed that responsive group exhibited significantly lower values in age, SDNN, SDANN, and VLF compared to the non-responsive group (all P<0.05). Multivariate Logistic regression analysis showed that age ( OR=1.47, 95% CI 1.08-2.01), SDNN ( OR=1.01, 95% CI 1.00-1.22) and VLF ( OR=1.01, 95% CI 1.00-1.15) were independent influencing factors in the effect of vitamin D in POTS children (all P<0.05). ROC curve analysis showed that the area under the curve of VLF predicting response to vitamin D treatment for POTS was 0.72 (95% CI 0.58-0.85, P=0.008). When the cutoff value was 1 272 ms 2, the sensitivity and specificity were both 70%. Conclusion:VLF may help predict the efficacy of vitamin D treatment in children with POTS.

Objective:To explore the screening value of platelet parameters from blood cell analysis for MYH9-related disorders(MYH9-RD).Methods:A cross-sectional study was conducted with 38 patients diagnosed with MYH9-RD at Shenzhen Children's Hospital from May 1, 2016, to August 31, 2024, including 24 males and 14 females; the median age was 11.5 (3.8, 35) years; categorized by gene mutation location into "head region" ( n=8 ) and "tail region" ( n=30); and by clinical manifestations into " isolated hematological manifestations" ( n=16) and "hematological manifestations with extra-hematological involvement"( n=22). The control groups included 39 cases of immune thrombocytopenia (ITP), 38 cases of acute lymphoblastic leukemia (ALL), and 40 healthy individuals. Platelet-related parameters were detected by hematology analyzer, and platelet counts and sizes were confirmed by manually counting and microscopic observation. Kruskal-Wallis test was used to compare platelet parameters between MYH9-RD and control groups. Receiver operating characteristic (ROC) curves were used to assess the diagnostic efficacy of platelet parameters for MYH9-RD. Results:In MYH9-RD patients the median value of mean platelet volume (MPV) was 13.4 (11.2, 14.7) fl, immature platelet fraction (IPF) was 52.7% (43.5%, 58.0%), platelet large cell ratio(PLCR) was 57.6 %(45.0%, 62.9%), and microscopic large platelet ratio (PLCR-M) was 30.0% (25.0%, 30.0%).And those values weresignificantly higher than in ITP, ALL, and healthy controls (all P<0.05). Patients with MYH9 gene "head region" mutations had a lower platelet count [24.5 (15.0, 47.5)×10 9/L]than those with "tail region" mutations [69.0 (49.5, 86.3) ×10 9/L]( Z=-3.493, P<0.001), but a higher IPF ( t=2.024, P=0.044).Patients with "extra-hematological involvement had a lower platelet count than those with "isolated hematological manifestations" ( t=-2.015, P=0.043). The optimal cutoff value for diagnosing MYH9-RD with IPF was 26.7%, with a sensitivity of 100% and specificity of 98.7%; the area under the curve was 0.999 (95% CI 0.995-1.000), which was superior toMPV, PLCR and PLCR-M parameters. Conclusion:IPF is superior to other platelet parameters sush as MPV,showing high diagnostic efficacy in distinguishing MYH9-RD from ITP and ALL. It can be used as a simple and effective indicator for early screening of MYH9-RD.

Objective:To investigate the correlation between the expression of the immunohistochemical marker cytokeratin (CK)-19 and the clinical characteristics and prognosis of dual-phenotype hepatocellular carcinoma (DPHCC).Methods:The data of patients diagnosed with hepatocellular carcinoma (HCC) who underwent surgical resection were collected. DPHCC cases were screened by immunohistochemistry, followed up, and grouped. The correlation between the expression of the immunohistochemical marker CK-19 and the clinical pathological characteristics and prognosis of DPHCC was analyzed by statistical methods. The enumeration data were compared using the χ2 test or Fisher's exact probability method between groups. Results:The expression of CK19 was significantly correlated with factors such as the tumor size, histological grade, liver tissue cirrhosis surroundings, microvascular invasion (MVI), and serum carbohydrate antigen 199 (CA-199) levels in DPHCC, and the differences were statistically significant ( P<0.05). There was no significant correlation between the expression of CK19 and the gender, age, tumor necrosis, multiple lesions, liver capsule invasion, serum alpha-fetoprotein (AFP), and immunohistochemical CK7 and mucin 1 (MUC-1) in DPHCC patients, and the differences were not statistically significant ( P>0.05). The results of univariate analysis showed that immunohistochemical CK19 expression, MVI, number of lesions, tumor necrosis, tumor differentiation degree, serum AFP, and carbohydrate antigen 199 levels were related factors affecting the prognosis in DPHCC patients ( P<0.05); while gender, age, capsule invasion, tumor size, and expression of immunohistochemical markers (vascular endothelial growth factor, CK7, MUC-1) were not significantly correlated with the prognosis in DPHCC patients ( P>0.05). The results of multivariate analysis showed that tumor necrosis ( P=0.042, 95% CI: 1.031-5.501) and serum AFP levels were independent risk factors affecting the prognosis in DPHCC patients ( P<0.001, 95% CI: 2.581-24.075). Conclusions:The expression of CK19 is closely related to the prognosis of patients with DPHCC. Patients with high CK19 expression have faster disease progression than those with low CK19 expression. Furthermore, the overall survival rate of patients with high CK19 expression is significantly lower than that of patients with low CK19 expression, which is a risk factor for poor prognosis in patients with DPHCC.
