Objective:To identify the relationship between the CT arterial radiomics score and the treatment response to neoadjuvant therapy for pancreatic cancer.Methods:The clinical data of 243 pancreatic cancer patients who received surgical resection after neo-adjuvant therapy in the First Affiliated Hospital of Naval Medical University from March 2017 to March 2023 were retrospectively analyzed. Based on the tumor regression grade (TRG), the patients were divided into good response group (TRG 0-1, n=30) and non-good response group (TRG 2-3, n=213). The clinical, radiological and pathological features were compared between two groups. Fully-automated segmentation tool was used for segmenting the arterial CT scan of pancreatic tumor before and after treatment. Python package was applied to extract the radiomics features of tumors after segmentation and the extracted features were reduced and chosen using the least absolute shrinkage and selection operator (Lasso) logistic regression algorithm. Lasso logistic regression formula was applied to calculate the arterial radiomics score. Univariate and multivariate logistic regression models were used to analyze the association between arterial radiomics score and treatment response to neoadjucant therapy. Receiver operating-characteristics (ROC) curve was drawn and area under curve (AUC), specificity, sensitivity and accuracy for evaluating the treatment response were calculated. The clinical usefulness of arterial radiomics score for diagnosing the response of neoadjuvant treatment for pancreatic cancer were determined by decision curve analysis (DCA) . Results:A total of 330 arterial radiomics CT features were obtained, and 9-selected arterial phase features associated with treatment response were determined after being reduced by the Lasso logistic regression algorithm. Univariate analysis showed that the arterial radiomics score, three-dimensional diameter after neoadjuvant therapy, pancreatic contour, T stage, N stage, Peri-pancreatic nerve invasion, lymph-vascular space invasion (LVSI) and invasion of duodenum were all associated with treatment response (all P value <0.05). Multivariate logistic regression analyses confirmed that arterial radiomics score was obviously associated with the neoadjuvant treatment response ( P<0.001). At the cut-off value of 1.93, AUC of the arterial radiomics score for diagnosing neoadjuvant treatment response was 0.92, and the specificity, sensitivity and accuracy was 86.7%, 84.5% and 84.8%. DCA demonstrated that when the percentage for predicting the treatment response by using the arterial radiomics score was >0.2, the patients could benefit from the application of arterial radiomics score for evaluating neoadjuvant therapy response. Conclusions:The arterial radiomics score was strongly correlated with the neoadjuvant treatment response of pancreatic cancer, and can accurately predict neoadjuant treatment efficacy.

Objective:To investigate the effect of quality control circle(QCC)activity management on operation time,cardiac function and prognosis in patients with acute myocardial infarction(AMI)undergoing percutaneous coronary intervention(PCI).Methods:A total of 148 AMI patients who admitted to the emergency department of our hospital and underwent PCI from January to June 2021 were selected.According to different hospital manage-ment patterns,patients were divided into control group(n=74)and QCC group(n=74).Emergency detention time,PCI time,cardiac function indexes at 7d and 14d after PCI,patient satisfaction and incidence of adverse car-diovascular events on six months after PCI were compared between two groups.Results:Compared with control group,there were significant reductions in ECG monitoring time[(11.35±2.13)min vs.(9.14±1.86)min],condition evaluation time[(14.78±2.51)min vs.(10.12±2.28)min],drug preparation time[(29.69±5.03)min vs.(22.65±4.52)min]and PCI time[(83.47±10.76)min vs.(62.18±10.03)min]in QCC group,P=0.001 all.Compared with control group on 14d after PCI,there was significant rise in left ventricular ejection frac-tion(LVEF)[(46.42±2.52)％vs.(58.54±1.82)％],and significant reductions in left ventricular end-systolic volume index(LVESVI)[(33.05±3.47)ml/m2 vs.(28.22±2.49)ml/m2]and left ventricular end-diastolic volume index(LVEDVI)[(69.08±4.53)ml/m2 vs.(56.85±2.48)ml/m2]in QCC group,P＜0.01 all.Total satisfaction of QCC group was significantly higher than that of control group(93.24％vs.62.16％),and incidence rate of adverse cardiovascular events on six months after PCI was significantly lower than that of control group(12.16％vs.36.49％),P=0.001 both.Conclusion:QCC activity management intervention can optimize clinical PCI procedure,significantly shorten emergency detention time,operation time,improve cardiac function,reduce postoperative incidence rate of cardiovascular adverse events.It possesses high satisfaction and is worthy of clinical promotion and application.

The liver plays an important regulatory role in maintaining the dynamic balance of coagulation and anticoagulation in the body. Such dynamic balance is fragile in patients with liver cirrhosis， and the risk of bleeding can be increased due to reductions in coagulation factors and platelet count and excessive fibrinolysis； meanwhile， thrombus can be formed due to the increases in von Willebrand factor and coagulation factor Ⅷ， the reductions in anticoagulant protein C and anticoagulant protein S， the increase in thrombin-generating potential， and alterations in antifibrinolytic components. This article reviews the mechanisms of coagulation disorder in liver cirrhosis， so as to help clinicians with the prevention and treatment of bleeding or thrombotic disorders in patients with liver cirrhosis.

Objective:To examine the risk factors and predictive value of depression following mild acute ischemic stroke in elderly individuals.The aim is to enhance early identification and intervention, ultimately leading to improved prognosis.Methods:A case-control study was conducted on 988 elderly patients with mild acute ischemic stroke.The study collected general population and social data, as well as clinical laboratory data such as blood glucose, blood lipids, and AD7C-NTP in urine.Additionally, the patients underwent assessments using the Montreal Cognitive Assessment Scale(MoCA), National Institutes of Health Stroke Scale(NHISS), Barthel index(BI), Hamilton Anxiety Scale(HAMA), and Hamilton Depression Scale(HAMD).Based on the HAMD depression scale score, the patients were divided into a nopost-stooke depression(NPSD)group and a post-stooke depression(PSD)group.The study then analyzed the related risk factors and predictive value of PSD.Results:A total of 988 patients were eligible for inclusion, with 132 being excluded and 856 being included.The NPSD and PSD groups showed significant differences in age, hypertension, smoking history, education level, and stroke history(all P<0.05).Regarding clinical data, there were statistically significant differences between the two groups in total cholesterol(TC), triacylglycerol(TG), HDL, urinary AD7C-NTP, MoCA, and HAMA scores(all P<0.05).The results of the multi-factor logistic regression analysis revealed that gender( OR=1.975, 95% CI: 1.223-3.190, P=0.005), stroke history( OR=1.352, 95% CI: 0.877-2.086, P=0.042), and HAMA score( OR=1.216, 95% CI: 0.932-1.526, P=0.043)were identified as independent risk factors for post-stroke depression in the elderly.Conversely, MoCA score( OR=0.873, 95% CI: 0.814-0.937, P<0.001)was found to be an independent protective factor.Furthermore, the ROC curve analysis demonstrated that the HAMA score(AUC=0.892, sensitivity: 0.721, specificity: 0.854, cut-off value: 9.5)exhibited significant predictive value, while the other indexes had limited predictive value. Conclusions:Gender, stroke history, and HAMA score have been identified as potential independent risk factors for post-stroke depression(PSD)in the elderly, while MoCA score may serve as an independent protective factor.Notably, HAMA score demonstrates a strong predictive ability for PSD.Early identification of these factors and timely intervention could significantly contribute to improving prognosis.

The practice form of medical humanities has the most fundamental significance among many forms of medical humanities.The value of medical humanities can only be truly realized and exert a practical impact across different levels and areas of healthcare when other forms are ultimately transformed into practical processes and achieve practical results.Clinical practice is the main venue for the practice of medical humanities,and the doctor-patient relationship is the primary field where medical humanities exert their influence.In the fields of social health care system construction,medical education and its reform,medical humanities can really play a role through its practice form and operation process.It is the essence of medical humanities that practice forms play a role effectively.The effective role of practice is the essential prescriptive nature of medical humanities.

Psychiatric ethics is a component of Fan Ruiping's book Contemporary Medicine and Confucian Thought with unique academic perspectives.Fan Ruiping stood from the Confucian bioethical standpoint,analyzing and criticizing the medical individualism stance reflected in Article 30 of the Mental Health Law.of People's Republic of china on the voluntariness principle of in-patient therapy for mental disorders.Based on the comparison of cognitive paths and practical methods of bioethics in Eastern and Western,through in-depth analysis of multiple cases,he reflected on how Confucian psychiatric ethics should develop in the contemporary era and the necessity of improving Confucian family-oriented ethical practices.With the help of Fan Ruiping's cognitive conclusions,this paper questioned the moral basis of Article 30 of the Mental Health Law,discussed the special ethical regulations of the"autonomy"of patients with mental disorders,and advised Fan Ruiping's on the multifaceted issues confronting Confucian family ethics in response to international psychiatric ethics.

Objective To explore the expression levels of SPARC related modular calcium binding 1(SMOC1)and olfactomedin-3(OLFM3)in the cerebrospinal fluid of Alzheimer's disease(AD)patients and their value in evaluating the severity of the disease.Methods A total of 108 AD patients(AD group)treated at Baoji People's Hospital from January 2020 to January 2023 were selected,and 60 non cognitive dysfunction patients who underwent lumbar puncture examination during the same period were selected as the control group.Enzyme-linked immunosorbent assay(ELISA)was used to detect cerebrospinal fluid SMOC1,OLFML3,β-Amyloid protein(Aβ1-40,Aβ1-42)and P-Tau protein levels.Pearson correlation analysis was conducted to analyze cerebrospinal fluid SMOC1,and OLFML3 levels and their correlation with clinical indicators.Logistic regression was used to analyze the influencing factors of AD severity.Receiver operating characteristic curves were used to analyze the predictive value of cerebrospinal fluid SMOC1 and OLFML3 on the severity of Alzheimer's disease.Results The levels of SMOC1(68.47±11.23 ng/L),OLFML3(110.58±21.39 ng/L),P-Tau(569.07±97.24 ng/L)and CDR score(1.5 score)in the cerebrospinal fluid of the AD group were higher than those in the control group(22.60±4.16 ng/L,36.94±6.97ng/L,182.66±55.37,0 score),while Aβ1-42(292.23±55.36 ng/L),MoCA score(7.88±2.05 score)and MMSE score(13.15±2.39 score)were lower than those in the control group(397.16±60.57ng/L,23.13±4.31 score,28.02±4.26 score),and the differences were statistically significant(t=30.465,25.885,28.313,51.211,11.380,31.038,29.013,all P＜0.05).SMOC1 and OLFML3 of the cerebrospinal fluid in the AD group were positively correlated with P-Tau and CDR score(r=0.703,0.634;0.682,0.713,all P＜0.05),but were negatively correlated with Aβ1-42,MoCA score and MMSE score(r=-0.662,-0.599;-0.660,-0.588;-0.745,-0.731,all P＜0.05).SMOC1(89.90±12.17 ng/L),OLFML3(142.46±22.48),and P-Tau(618.83±98.19 ng/L)in the cerebrospinal fluid of AD patients in the moderate to severe group were higher than those in the mild group(56.36±10.52 ng/L,92.56±20.25 ng/L,542.25±95.30 ng/L),Aβ1-42 in the moderate to severe group(260.76±53.60 ng/L)was lower than those in the mild group(310.02±56.54 ng/L),and the differences were statistically significant(t=15.029,11.818,3.968,4.430,all P<0.05).SMOC1(OR=1.451,95%CI:1.120～1.879),OLFML3(OR=1.442,95%CI:1.096～1.897)and P-Tau(OR=1.589,95%CI:1.258～2.006)in cerebrospinal fluid were risk factors for moderate to severe cognitive impairment in AD patients,while Aβ1-42 was a protective factor.The AUC(95%CI)of SMOC1,OLFML3 in cerebrospinal fluid,and their combinative forecasting evaluating moderate to severe AD patients were 0.882(0.844～0.929),0.846(0.805～0.877)and 0.931(0.883～0.965),respectively,and their combinative forecasting was higher than two individual indicators(Z=3.558,4.172,P=0.004,0.000).Conclusion The levels of SMOC1 and OLFML3 in cerebrospinal fluid are elevated in AD patients,which are related to the severity of AD.The combinative forecasting of the two has high predictive value for moderate to severe AD.

Trace amines(TAs)are metabolically related to catecholamine and associated with cancer and neuro-logical disorders.Comprehensive measurement of TAs is essential for understanding pathological pro-cesses and providing proper drug intervention.However,the trace amounts and chemical instability of TAs challenge quantification.Here,diisopropyl phosphite coupled with chip two-dimensional(2D)liquid chromatography tandem triple-quadrupole mass spectrometry(LC-QQQ/MS)was developed to simul-taneously determine TAs and associated metabolites.The results showed that the sensitivities of TAs increased up to 5520 times compared with those using nonderivatized LC-QQQ/MS.This sensitive method was utilized to investigate their alterations in hepatoma cells after treatment with sorafenib.The significantly altered TAs and associated metabolites suggested that phenylalanine and tyrosine metabolic pathways were related to sorafenib treatment in Hep3B cells.This sensitive method has great potential to elucidate the mechanism and diagnose diseases considering that an increasing number of physiological functions of TAs have been discovered in recent decades.

OBJECTIVE: To investigate the risk factors of oral ulcers and bloodstream infection in patients with hematopoietic stem cell transplantation. METHODS: The clinical data of 401 hematopoietic stem cell transplant patients in the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2021 were retrospective analyzed, and the risk factors of oral ulcers and bloodstream infection statistical and analyzed. RESULTS: Among the 401 patients, the incidence of oral ulcers was 61.3% (246/401), and the incidence of bloodstream infection was 9.0% (36/401). A total of 40 strains of pathogenic bacteria were isolated from 36 patients, including 26 strains of Gram negative strains (65%), 13 strains of Gram positive strains (32.5%), and 1 strain of fungi (2.5%). Single-factor analysis showed that oral hygiene was associated with the occurrence of bloodstream infection, and the Multi-factor analysis showed that age ≥14 years old, disease diagnosis of leukemia, and allogeneic hematopoietic stem cell transplantation were risk factors for oral ulcers. CONCLUSION The incidence of oral ulcers in patients with hematopoietic stem cell transplantation is high. The age ≥14 years, disease diagnosis of leukemia, and allogeneic hematopoietic stem cell transplantation were risk factors for oral ulcers in patients, and oral hygiene was associated with the occurrence of bloodstream infection.

Objective:To explore the risk factors for cognitive impairment 3 months after an ischemic stroke and their predictive value.Methods:A retrospective case-control study considered the records of 856 elderly patients who had survived an ischemic stroke. All had been evaluated using the Montreal Cognitive Assessment scale (MoCA). They were divided according to their MoCA scores into a group without cognitive impairment (the PSNCI group) and an impaired (PSCI) group. The subjects′ demographic and clinical laboratory data were compiled. All had been assessed using the National Institutes of Health stroke scale (NIHSS), the Barthel Index (BI), and the Hamilton depression scale (HAMD). Univariate and multivariate logistic regressions were evaluated and a receiver operator characteristics (ROC) curve was computed.Results:There were significant differences between the two groups in terms of gender distribution, age, hypertension and heart disease history, family history of dementia and education level. Moreover, significant differences were observed in the groups′ average total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), urinary neurofilament protein (AD7c-NTP), NIHSS scores, BIs and ADL scores. Logistic regression showed that a history of heart disease, urinary AD7C-NTP level and HAMD score were significant independent predictors of cognitive impairment 3 months after a stroke. A high BI was an independent protective factor. The area under the ROC curve for urinary AD7C-NTP was the largest (0.875) and had significant predictive value with a cut-off value of 2.43, sensitivity of 0.94 and specificity of 0.75.Conclusion:Age, sex, education, smoking, drinking, body mass index, a history of heart disease or stroke, a family history of dementia and elevated AD7C-NTP, TC or TG are risk factors for cognitive impairment after a stroke. A high BI suggests a better prognosis. Urinary AD7c-NTP is a useful predictor of PSCI 3 months after a stroke.
