The red doctor spirit is the advanced culture of the Communist Party of China formed under a specific historical and cultural background. It can be summarized as “political firmness， excellent technology， working hard， and healing the wounded and rescuing the dying.” This content has many hidden similarities and integrations with the goal of cultivating humanistic literacy for medical students in military medical universities. This paper aimed to identify the important connection points between the red doctor spirit and the contents and goals of medical humanities teaching， as well as integrate the red doctor spirit into medical humanities teaching by various dimensions， including systematic reconstruction of textbook content， immersive innovation in teaching form， three-dimensional support in resource construction， and innovative implementation of narrative medicine teaching. It also further explored the extension of the red doctor spirit in military medical humanistic literacy， namely， revolutionary humanism and revolutionary heroism， thereby enhancing the effectiveness of medical humanistic teaching.

OBJECTIVES: To explore the association of the expression of WW domain-containing ubiquitin E3 ligase 1 (WWP1) with immune infiltration in tumor microenvironment (TME) of ovarian cancer. METHODS: Ovarian cancer patient data from The Cancer Genome Atlas (TCGA) were used to analyze the association of WWP1 expression with patient prognosis. TISCH2 was utilized to analyze the changes in immune cell subtypes in TME of metastatic tumor and after chemotherapy. The impact of WWP1 on immune cell infiltration, somatic copy number alterations of WWP1 and evolution of immune cell subtypes was evaluated using TIMER and TIGER pseudo-time analysis. A deep learning model was used to analyze TCGA pathological images to investigate the effect of WWP1 on TME of ovarian cancer. RNA-seq analysis was conducted to identify the differentially expressed genes in WWP1-overexpressing SKOV3 cells and validate immune infiltration. Multicolor immunofluorescence assay was used to analyze the immune markers in SKOV3 and SKOV3/DDP cell xenografts in nude mice. RESULTS: The patients with high WWP1 expression levels had significantly lower overall survival rate (P=0.0012). High WWP1 expression levels and Stage IV disease were both associated with a poor prognosis (P<0.05). In metastatic ovarian cancer or after chemotherapy, the percentages of malignant tumor cells and tumor-associated fibroblasts increased in the TME, accompanied by elevated WWP1 levels. WWP1 expression level was positively correlated with pro-tumorigenic immunosuppressive cells (r=0.1323-0.3955, P<0.05) and negatively with tumor-inhibiting immune cells (r=-0.1949- -0.1333, P<0.05). Specific copy number alterations of WWP1 also influenced CD8⁺ T cell percentage and neutrophil infiltration levels in the TME. RNA-seq analysis of WWP1-overexpressing SKOV3 cells and immunofluorescence assay of the tumor-bearing mice yielded findings consistent with those of bioinformatics analysis. CONCLUSIONS WWP1 may serve as a prognostic biomarker and a potential target for immune regulation in the TME of ovarian cancer.

ObjectiveTo investigate the effect of the multidisciplinary team （MDT） management model in improving the prognosis of patients with cirrhotic portal hypertension. MethodsA total of 86 patients with cirrhotic portal hypertension who were admitted to Shenzhen Third People’s Hospital from May 2022 to July 2024 were enrolled， and according to whether the MDT treatment regimen was implemented， they were divided into execution group with 51 patients and non-execution group with 35 patients. Baseline clinical data were collected， and the patients were observed in terms of gastrointestinal bleeding， hepatic encephalopathy， liver cancer， and death from admission to the end of follow-up （January 2025）. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to plot survival curves for the cumulative incidence rates of endpoint events （gastrointestinal bleeding， hepatic encephalopathy， liver cancer， and death）， and the Log-rank test was used for comparison between groups. The Cox proportional-hazards regression model analysis was used to investigate the effect of MDT management on the prognosis of patients. ResultsThere were significant differences between the execution group and the non-execution group in diameter of the portal vein （t=1.216， P=0.017） and ascites （χ²=4.515， P=0.034） at baseline. The patients were followed up for 14.6±6.2 months， and the survival curve analysis showed that there was a significant difference in the cumulative incidence rate of gastrointestinal bleeding between the two groups （χ²=4.573， P=0.024）， while there were no significant differences in the incidence rates of other outcome events between the two groups （all P>0.05）. The Cox regression analysis showed that the execution group had a reduced risk of gastrointestinal bleeding （hazard ratio=0.262， 95% confidence interval： 0.110 — 0.630， P=0.003）. ConclusionImplementation of the MDT treatment regimen can significantly reduce the short-term risk of gastrointestinal bleeding in patients with cirrhotic portal hypertension， while its long-term benefits require further follow-up verification.

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 This study aims to explore the effects of Minimally Invasive Extracorporeal Circulation(MECC)on systemic inflammatory response and transfusion requirements following Coronary Artery Bypass Grafting(CABG).Methods A total of 126 patients who underwent CABG from January 2023 to January 2024 were selected and randomly divided into an observation group and a control group,with 63 patients in each group.The observation group received MECC,while the control group was treated with Conventional Extracorporeal Circulation(CECC).Inflammatory response indicators,immune system function,coagulation function,renal function,cardiac function,and clinical symptoms were monitored preoperatively and at 24,48,and 72 hours postoperatively for comparison and analysis.Results At 24 hours postoperatively,CRP,IL-6 and TNF-α levels in the observation group were(18.5±3.7)mg/L,(15.2±3.4)pg/mL and(25.3±5.6)pg/mL,respectively,which were significantly lower than those in the control group(P＜0.05).At 48 hours postoperatively,the CD4+/CD8+ratio in the observation group was 1.6±0.3,which was higher than that in the control group(P＜0.05).At 72 hours postoperatively,the PT and APTT in the observation group were(12.1±1.2)seconds and(30.4±3.2)seconds,respectively,which were significantly lower than those in the control group(P＜0.05).Additionally,72 hours after surgery,SCr and BUN in the observation group were(1.1±0.2)mg/dL and 14.6±3.1 mg/dL,respectively,which were significantly lower than those in the control group(P＜0.05).In terms of cardiac function indexes,at 24 hours postoperatively,CI,LVEF,cTnⅠ and BNP in the observation group were(2.6±0.5)L/min/m2,(55.6±4.0)％,(0.14±0.03)ng/mL,and(280±30)pg/mL,respectively,which were significantly better than those in the control group(P＜0.05).At all postoperative time points,the VAS score,complication rate,length of hospital stay and ICU stay were significantly better in the observation group than in the control group(P＜0.05),with the VAS score at 24 hours postoperatively being(4.8±1.2)compared to(5.5±1.3)in the control group(P＜0.05).Conclusions MECC demonstrates significant advantages in attenuating systemic inflammatory response after CABG,protecting multi-system function,reducing postoperative blood transfusion requirements,and improving postoperative recovery.Compared with traditional extracorporeal circulation,MECC effectively reduce postoperative inflammatory reactions and complications,enhancing the quality of life for patients post-surgery,and shows broad clinical application prospects.

Objective To predict whether antiviral therapy is required in patients with chronic hepatitis B virus(HBV)infection and an age of≤30 years by establishing a noninvasive model,and to investigate the diagnostic value of this model.Methods A retrospective analysis was performed for the clinical data of 175 patients with chronic HBV infection who were admitted to Shenzhen Third People's Hospital from January 2017 to January 2023 and met the inclusion criteria,and according to the results of liver biopsy,they were divided into treatment group with 41 patients(with indications for antiviral therapy)and observation group with 134 patients(without indications for antiviral therapy).The two groups were analyzed in terms of the indicators including clinical data,imaging examinations,and serum biochemical parameters.The univariate and multivariate Logistic regression analyses were used to investigate the parameters affecting the indication for antiviral therapy,and different models for predicting the need for antiviral therapy were constructed based on related parameters.The receiver operating characteristic(ROC)curve was used to compare the diagnostic value of different models.The independent-samples t test was used for comparison of normally distributed continuous variables between groups,and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous variables between groups;the chi-square test or the Fisher's exact test was used for comparison of categorical data between groups.Results There were significant differences between the treatment group and the observation group in alanine aminotransferase,ferritin,total cholesterol(CHOL),triglyceride,platelet count,liver stiffness measured by sound touch elastography(STE),and procollagen Ⅲ N-terminal propeptide(PIIIP)(all P<0.05).The multivariate Logistic regression analysis showed that CHOL(odds ratio[OR]=0.4,95％confidence interval[CI]:0.2—1.0),STE(OR=1.5,95％CI:1.0—2.1),and PIIIP(OR=1.1,95％CI:1.0—1.1)were independent predictive factors for the indications for antiviral therapy.Model 1(STE+PIIIP+CHOL),model 2(STE+PIIIP),model 3(STE+CHOL),model 4(PIIIP+CHOL)had an area under the ROC curve of 0.908,0.848,0.725,and 0.725,respectively,while STE,PIIIP,and CHOL used alone had an AUC of 0.836,0.725,and 0.634,respectively,suggesting that model 1 had the largest AUC,with a specificity of 77.34％and a sensitivity of 96.36％,and had a significant difference compared with STE,PIIIP,CHOL,and the models 2,3,and 4(Z=0.21,3.08,3.06,3.23,0.89,and 0.88,all P<0.05).Conclusion The noninvasive model established based on CHOL,STE,and PIIIP has a good value in predicting the need for antiviral therapy in patients with chronic HBV infection and an age of≤30 years.

Background The incidence of mental disorders is steadily increasing.However,antipsychotic medications,commonly used in treatment,can lead to drug-induced amenorrhea in female patients.This side effect significantly reduces medication adherence and increases the risk of disease recurrence.Therefore,addressing drug-induced amenorrhea in female patients has become an urgent problem requiring effective solutions.Objective To explore the efficacy and safety of traditional Chinese medicine compound in treating antipsychotic-induced amenorrhea,so as to provide guidance for the treatment of this condition using traditional Chinese medicine compound.Methods On September 4,2022,a computerized search was conducted on across multiple databases,including China National Knowledge Infrastructure,VIP Database,Wanfang Database,China Biomedical Literature Database,PubMed,Cochrane Library and Embase,and randomized controlled trials(RCT)of traditional Chinese medicine compound in treating antipsychotic-induced amenorrhea were collected.The quality of the included literature was assessed using Cochrane 5.3 bias risk assessment tool.Meta-analysis was performed to assess the total effective rate,cure rate,incidence of adverse reactions and recurrence rate using RevMan 5.3.Results Ultimately,22 RCT involving 1879 patients were included.Meta-analysis results showed that the total effective rate(RR=1.29,95%CI:1.16～1.44)and cure rate(RR=1.62,95%CI:1.45～1.80)of traditional Chinese medicine compound or its combination with western medicine in treating antipsychotic-induced amenorrhea were significantly higher compared to western medicine alone.Moreover,the incidence of adverse reactions(RR=0.56,95%CI:0.41～0.76)and recurrence rate(RR=0.16,95%CI:0.06～0.42)were significantly lower than those of western medicine alone.Conclusion Traditional Chinese medicine compound may offer benefits in ameliorating antipsychotic-induced amenorrhea and its safety is better than simple western medicine treatment.

【Objective】 To objectively evaluate the quality control level of blood testing process in blood banks through quantitative monitoring and trend analysis, and to promote the homogenization level and standardized management of blood testing laboratories in blood banks. 【Methods】 A quality monitoring indicator system covering the whole process of blood collection and supply, including blood donation service, blood component preparation, blood testing, blood supply and quality control was established. The questionnaire Quality Monitoring Indicators for Blood Collection and Supply Process with clear definition of indicators and calculation formulas was distributed to 17 blood banks in Shandong province. Quality monitoring indicators of each blood bank from January to December 2022 were collected, and 31 indicators in terms of blood testing were analyzed using SPSS25.0 software. 【Results】 The proportion of unqualified serological tests in 17 blood bank laboratories was 55.84% for ALT, 13.63% for HBsAg, 5.08% for anti HCV, 5.62% for anti HIV, 18.18% for anti TP, and 1.65% for other factors (mainly sample quality). The detection unqualified rate and median were (1.23±0.57)% and 1.11%, respectively. The ALT unqualified rate and median were (0.74±0.53)% and 0.60%, respectively. The detection unqualified rate was positively correlated with ALT unqualified rate (r=0.974, P<0.05). The unqualified rate of HBsAg, anti HCV, anti HIV and anti TP was (0.15±0.09)%, (0.05±0.04)%, (0.06±0.03)% and (0.20±0.05)% respectively. The average unqualified rate, average hemolysis rate, average insufficient volume rate and the abnormal hematocrit rate of samples in 17 blood bank laboratories was 0.21‰, 0.08‰, 0.01‰ and 0.02‰ respectively. There were differences in the retest concordance rates of four HBsAg, anti HCV and anti HIV reagents, and three anti TP reagents among 17 blood bank laboratories (P<0.05). The usage rate of ELISA reagents was (114.56±3.30)%, the outage rate of ELISA was (10.23±7.05) ‰, and the out of range rate of ELISA was (0.90±1.17) ‰. There was no correlation between the out of range rate, outrage rate and usage rate (all P>0.05), while the outrage rate was positively correlated with the usage rate (r=0.592, P<0.05). A total of 443 HBV DNA positive samples were detected in all blood banks, with an unqualified rate of 3.78/10 000; 15 HCV RNA positive samples were detected, with an unqualified rate of 0.13/10 000; 5 HIV RNA positive samples were detected, with an unqualified rate of 0.04/10 000. The unqualified rate of NAT was (0.72±0.04)‰, the single NAT reaction rate [(0.39±0.02)‰] was positively correlated with the single HBV DNA reaction rate [ (0.36±0.02) ‰] (r=0.886, P<0.05). There was a difference in the discriminated reactive rate by individual NAT among three blood bank laboratories (C, F, H) (P<0.05). The median resolution rate of 17 blood station laboratories by minipool test was 36.36%, the median rate of invalid batch of NAT was 0.67%, and the median rate of invalid result of NAT was 0.07‰. The consistency rate of ELISA dual reagent detection results was (99.63±0.24)%, and the median length of equipment failure was 14 days. The error rate of blood type testing in blood collection department was 0.14‰. 【Conclusion】 The quality monitoring indicator system for blood testing process in Shandong can monitor potential risks before, during and after the experiment, and has good applicability, feasibility, and effectiveness, and can facilitate the continuous improvement of laboratory quality control level. The application of blood testing quality monitoring indicators will promote the homogenization and standardization of blood quality management in Shandong, and lay the foundation for future comprehensive evaluations of blood banks.
