BACKGROUND:Osteosarcoma has a complex pathogenesis and a poor prognosis.While advancements in medical technology have led to some improvements in the 5-year survival rate,substantial progress in its treatment has not yet been achieved. OBJECTIVE:To screen key molecular markers in osteosarcoma,analyze their relationship with osteosarcoma treatment drugs,and explore the potential disease mechanisms of osteosarcoma at the molecular level. METHODS:GSE99671 and GSE284259(miRNA)datasets were obtained from the Gene Expression Omnibus database.Differential gene expression analysis and Weighted Gene Co-expression Network Analysis(WGCNA)on GSE99671 were performed.Functional enrichment analysis was conducted using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes separately for the differentially expressed genes and the module genes with the highest positive correlation to the disease.The intersection of these module genes and differentially expressed genes was taken as key genes.A Protein-Protein Interaction network was constructed,and correlation analysis on the key genes was performed using CytoScape software,and hub genes were identified.Hub genes were externally validated using the GSE28425 dataset and text validation was conducted.The drug sensitivity of hub genes was analyzed using the CellMiner database,with a threshold of absolute value of correlation coefficient|R|>0.3 and P<0.05. RESULTS AND CONCLUSION:(1)Differential gene expression analysis identified 529 differentially expressed genes,comprising 177 upregulated and 352 downregulated genes.WGCNA analysis yielded a total of 592 genes with the highest correlation to osteosarcoma.(2)Gene Ontology enrichment results indicated that the development of osteosarcoma may be associated with extracellular matrix,bone cell differentiation and development,human immune regulation,and collagen synthesis and degradation.Kyoto Encyclopedia of Genes and Genomes enrichment results showed the involvement of pathways such as PI3K-Akt signaling pathway,focal adhesion signaling pathway,and immune response in the onset of osteosarcoma.(3)The intersection analysis revealed a total of 59 key genes.Through Protein-Protein Interaction network analysis,8 hub genes were selected,which were LUM,PLOD1,PLOD2,MMP14,COL11A1,THBS2,LEPRE1,and TGFB1,all of which were upregulated.(4)External validation revealed significantly downregulated miRNAs that regulate the hub genes,with hsa-miR-144-3p and hsa-miR-150-5p showing the most significant downregulation.Text validation results demonstrated that the expression of hub genes was consistent with previous research.(5)Drug sensitivity analysis indicated a negative correlation between the activity of methotrexate,6-mercaptopurine,and pazopanib with the mRNA expression of PLOD1,PLOD2,and MMP14.Moreover,zoledronic acid and lapatinib showed a positive correlation with the mRNA expression of PLOD1,LUM,MMP14,PLOD2,and TGFB1.This suggests that zoledronic acid and lapatinib may be potential therapeutic drugs for osteosarcoma,but further validation is required through additional basic experiments and clinical studies.

Objective: To explore the latent class characteristics and related factors of health risk behaviors among higher vocational college students (referred to as vocational students) in the Wuling Mountain Area, so as to provide references for promoting their healthy development and formulating effective intervention measures. Methods: From April to June 2024, a stratified random cluster sampling method was used to survey 1 737 students from three higher vocational colleges in the Wuling Mountain Area (Xiangxi in Hunan, Enshi in Hubei, and Tongren in Guizhou). The study employed the Health risk Behavior Questionnaire for College Students, the Parent-Child Relationship Scale, the Social Support Scale, and the School Connection Scale for data collection. Latent class analysis (LCA) was used to examine the heterogeneous distribution characteristics of health risk behaviors among vocational students, and multivariate Logistic regression was applied to analyze the related factors of latent classes. Results: The LCA results identified three latent classes based on 12 health risk behaviors: the comprehensive high risk group (151 students, 8.7% ), the psychological distress group (883 students, 50.8%), and the low risk group (703 students, 40.5%). The distribution of latent classes showed statistically significant differences in gender and only child status ( χ 2=121.25, 9.85, both P <0.05). The low risk group scored higher in parent-child relationship (29.26±6.19), social support (63.98±18.16), and school connection (35.97± 7.71 ) compared to the comprehensive high risk group (27.28±6.03, 57.67±15.60, 32.97±7.55) and the psychological distress group (27.52±5.19, 62.06±14.54, 33.80±6.14) ( F =20.37, 23.51, 9.89, all P <0.05). Multivariate Logistic regression revealed that boys( OR =3.29) were more likely to belong to the comprehensive high risk group, social support ( OR =0.03, 0.21) and school connection ( OR =0.92, 0.96) were less likely to belong to both the comprehensive high risk and psychological distress groups (all P < 0.05). Conclusions There are three potential categories of healthharmful behaviors among vocational college students in Wuling Mountain Area. Schools, families and society should enhance the levels of parent-child relationship, school connections and social support for vocational college students of different categories to promote their physical and mental health development.

Objective To construct a Gabra3 gene knockout cell model and explore transcriptomic and proteomic alterations in murine neuronal cells,in order to investigate the molecular mechanisms underlying the increased depth of slow-wave sleep observed following Gabra3 deletion.Methods Multiple sgRNA sequences were designed,and the CRISPR/Cas9 system was used to knock out the Gabra3 gene in the murine GT1-7 neuronal cell line.Gene sequencing was performed to assess knockout efficiency,and TA cloning was used to validate the knockout results.Protein immunoblotting experiments were conducted to confirm the knockout,while cell proliferation assays were used to validate the knockout phenotype.Total RNA and protein were extracted for transcriptomic and proteomic sequencing,respectively.A range of bioinformatics analyses was conducted to assess the functional consequences of Gabra3 knockout in GT1-7 neuronal cells.Results Following Gabra3 gene knockout,pathways related to cortisol and aldosterone synthesis and secretion,as well as circadian rhythm,were significantly enriched.Three key genes,BMP2,GLI2,and DLL1,were identified.Proteomic profiling revealed widespread disturbances in protein expression following Gabra3 knockout.Conclusion Gabra3 gene knockout may increase slow-wave sleep depth by modulating the expression of hormone secretion-related genes and altering circadian regulatory pathways.

Objective To discuss the application of multi-parameters of coronary CT angiography(CTA)in diagnosing coronary heart disease(CHD)and predicting major adverse cardiovascular events(MACE)after percutaneous coronary intervention(PCI).Methods A total of 350 patients with CHD,who received PCI at the Affiliated Beijing Rehabilitation Hospital of Capital Medical University of China from January 2021 to January 2024,were enrolled in this study as observation group.Other 180 patients with suspected CHD,who underwent coronary CTA and coronary angiography(CAG)to exclude coronary artery lesion in the same period as in the observation group,were collected and used as control group.According to whether MACE occurred or not within 6 months after PCI,the patients of observation group were further divided into MACE group and non-MACE group.The CTA parameters,including total plaque volume(TPV),plaque burden(PB),remodeling index(RI),fat attenuation index(FAI)around coronary artery,spot calcification and napkin-ring sign,were compared between the observation group and the control group as well as between MACE group and non-MACE group.Logistic regression analysis was used to analyze the independent factors influencing the occurrence of MACE after PCI.Area under receiver operating characteristic curve(AUC)was adopted to assess the value of each parameter in predicting the occurrence of MACE within 6 months after PCI.Results The TPV,PB,RI,FAI,and the detection rate of spot calcification and napkin-ring sign in the observation group were significantly higher than those in the control group(P＜0.05).Of the 350 patients in the observation group,54(15.43％)developed MACE within 6 months after PCI,including cardiac death(n=5,1.43％),non-fatal myocardial infarction(n=22,6.29％),target vessel reconstruction due to in-stent restenosis(n=15,4.29％),and hospitalization due to heart failure(n=12,3.43％),all the 54 patients were classified in MACE group.The non-MACE group had 296 patients.The TPV,PB,RI,FAI,and the detection rate of napkin-ring sign in MACE group were higher than those in non-MACE group(P＜0.05).Logistic multivariate analysis showed that TPV,PB and FAI were the independent factors influencing the occurrence of MACE in CHD patients after PCI(P＜0.05).ROC curve analysis indicated that in predicting the occurrence of MACE within 6 months after PCI the sensitivity of TPV,PB and FAI were 65.40％,76.90％and 76.90％respectively,and the specificity of TPV,PB and FAI were 63.80％,72.50％and 73.80％respectively.The sensitivity and specificity of the combined detection were 96.20％and 71.80％respectively,with an AUC of 0.896.Conclusion Multi-parameters of coronary CT A have important application value in diagnosing CHD and in predicting the occurrence of MACE after PCI.The combined detection of TPV,PB and FAI can provide important reference for making clinical decision.

Malignancies are a difficult to treat disease in clinical practice.At present,there are many cases of differentiation and treatment based on qi and yin deficiency,the coagulation of phlegm,blood stasis and cancer toxin,there are few theories on the treatment of yang deficiency and yin excessiveness,as well as the coagulation of cold and dampness.On the basis of inheriting the cancer toxin theory of Chinese medicine master ZHOU Zhongying,combined with the theory of promoting yang and our own practice,we believe that malignancy is caused by yang deficiency as the foundation,cold dampness,phlegm-turbidity stagnation and toxin transformation as the manifestation,and the key pathogenesis can be summarized as yang deficiency and yin binding.Based on this,it is proposed to differentiate and treat malignancies from promoting yang and eliminating yin.The method of promoting yang and eliminating yin is people-oriented,with harmony as the value,based on the whole,with a focus on adjusting harmony,constantly promoting yang and timely eliminating yin.The specific differentiation and treatment strategies are as follows:in the early stages of malignancy,it is important to seize the opportunity to warm and dredge,or eliminate yin;malignancy is already present,balancing deficiency and excess,supplementing,eliminating,and harmonizing appropriately;after malignancy surgery,it is important to strengthen the foundation and regulate the spleen and kidney,and strengthen both congenital and acquired constitution;treating the zang-fu organs accordingly,elevating and lowering,and conforming to the physiology of the organs.Unlike simple malignancy treatment and detoxification,promoting yang and eliminating yin is a method of examining symptoms and identifying etiology and pathogenesis.It involves macroscopic regulation of yin and yang,dynamic management of medication,and orderly treatment,which can significantly improve the quality of life of patients and increase long-term survival rates.Exploring the theory and strategy of promoting yang and eliminating yin in the differentiation and treatment of malignancy can provide new ideas and references for the clinical differentiation and treatment of malignancies.

Objective:To observe the expression level of bone morphogenetic protein 9 (bone morphogenetic protein 9,BMP9) in patients with sepsis-associated acute respiratory distress syndrome (acute respiratory distress syndrome,ARDS), and to explore the role of BMP9 in early recognition and prognosis prediction of sepsis-associated ARDS.Methods:From May 2022 to May 2023, total of 56 patients with sepsis-associated ARDS in Shanxi Bethune Hospital were selected as the ARDS group, 49 patients with cardiogenic pulmonary edema as the case control group, and 46 adults who underwent physical examination in the physical examination center of our hospital as the healthy control group.The patients in the ARDS group were followed up for 28 days and divided into survival group ( n = 26) and death group ( n = 30). The expression level of serum BMP9 and its correlation with clinical indicators in each group were analyzed and compared. The risk factors of sepsis-associated ARDS were analyzed by Logistic regression, and the diagnostic efficacy and prognostic value of related indicators were analyzed. Results:The serum level of BMP9 in sepsis-associated ARDS group [1401.14 (856.59,1982.86) ]pg/mL was significantly higher than that in case control group (438.26±128.52) pg/mL and healthy control group (398.96±96.55)pg/mL, the differences were statistically significant ( P<0.01). In addition, BMP9 expression significantly correlated with procalcitonin, lymphocyte count and SOFA score ( P < 0.05, P < 0.01, respectively). Multivariate Logistic regression analysis showed that BMP9 was a high risk factor for the development of sepsis-associated ARDS ( P<0.01). The area under the ROC curve (area under the ROC curve,AUC) of BMP9 to predict the occurrence of sepsis-associated ARDS was 0.930. The specificity was 100.0% and the sensitivity was 80.4%, which was significantly higher than the specificity (89.8%) and sensitivity (67.9%) of the oxygenation index. Follow-up and comparison of BMP9 levels in patients with different prognosis of sepsis-associated ARDS showed that the expression level of BMP9 in the death group was higher than that in the survival group, and the difference was statistically significant ( P < 0.05). The ROC curve of BMP9 in predicting the prognosis of patients with sepsis-associated ARDS. The area under the ROC curve was 0.699, the sensitivity was 43.3%, and the specificity was 100.0%. Conclusions:The expression of BMP9 in sepsis-associated ARDS patients significantly increased, and its high expression was significantly correlated with inflammatory markers such as procalcitonin, lymphocyte count and SOFA score. BMP9 is an independent risk factor in patients with sepsis-associated ARDS, and it is promising as a new biomarker for early identification of sepsis-associated ARDS. However, it do not show a good predictive effect on the prognosis of the disease.

Objective:To explore the expression of growth differentiation factor 15 (GDF15) in patients with septic cardiomyopathy and its value in the diagnosis of septic cardiomyopathy.Methods:A observational study was conducted. Fifty patients with septic cardiomyopathy admitted to Shanxi Bethune Hospital from May 2022 to March 2023 were selected as the experimental group. Forty-six patients with acute coronary syndrome (ACS) in the same period were selected as the case control group. Forty-nine healthy adults were selected as the healthy control group, who underwent physical examination in the physical examination center during the same period. The demographic data and clinical indicators of the subjects were recorded, and the serum GDF15 level was detected by double sandwich enzyme-linked immunosorbent assay (ELISA). And the 28-day outcome of patients with septic cardiomyopathy was followed up, and they were divided into survival group and death group. The serum GDF15 level of subjects in each group and its correlation with clinical indicators were analyzed and compared. Binary Logistic regression was used to analyze the risk factors of septic cardiomyopathy. Receiver operator characteristic curve (ROC curve) was used to evaluate the value of GDF15 in the diagnosis of septic cardiomyopathy.Results:The serum GDF15 level of experimental group was significantly higher than that in the case control group and healthy control group [ng/L: 314.14 (221.96, 469.56) vs. 39.08 (26.27, 76.85), 6.39 (3.35, 14.42), both P < 0.01]. Correlation analysis showed that serum GDF15 level in patients with septic cardiomyopathy were correlated with cardiac troponin I (cTnI, r = 0.295, P = 0.038), brain natriuretic peptide (BNP, r = 0.464, P = 0.009), sequential organ failure assessment (SOFA, r = 0.363, P = 0.010) and acute physiology and chronic health evaluation Ⅱ (APACHEⅡ, r = 0.316, P = 0.025). However, there was no significant correlation with white blood cell count, neutrophil count, lymphocyte count, procalcitonin, C-reactive protein, lactic acid, albumin and other clinical indicators ( r values were 0.086, 0.123, -0.051, 0.055, 0.119, 0.199, -0.234, all P > 0.05). Serum GDF15 level, SOFA score and APACHEⅡ score in the death group (30 cases) were significantly higher than those in the survival group [20 cases; GDF15 (ng/L): 382.93±159.61 vs. 289.66±158.46, SOFA: 10.00 (7.00, 12.00) vs. 6.00 (5.00, 9.50), APACHEⅡ: 21.70±6.07 vs. 14.85±7.57, all P < 0.05]. Binary Logistic regression analysis showed that serum GDF15 was an independent risk factor for the onset of septic cardiomyopathy [odds ratio ( OR) = 1.062, 95% confidence interval (95% CI) was 1.011-1.115, P = 0.016]. ROC curve showed that the area under the curve (AUC) of GDF15 for predicting septic cardiomyopathy was 0.971, the specificity was 100%, and the sensitivity was 90.3%. Conclusion:The serum GDF15 level of patients with septic cardiomyopathy is significantly increased, and GDF15 may be used as an effective biomarker for the early diagnosis of septic cardiomyopathy.

Objective:This study proposed a novel technique for aortic root reconstruction and evaluated its safety and effectiveness.Methods:Acute type A aortic dissection (ATAAD) patients who underwent Sun' s procedure from January 2020 to June 2022 in the First Affiliated Hospital of Xi'an Jiaotong University were retrospectively enrolled. These patients were divided into three groups according to their surgical procedures of aortic root: aortic root reinforcement combined with vascular grafts built-in and intermittent anastomosis technique (XJ-procedure) group, continuous suture and pledgeted interrupted reinforcement group and Bentall group. The perioperative data and postoperative follow-up results of the three groups were compared to analyze the efficacy of XJ-procedure in the root treatment of ATAAD.Results:A total of 509 patients were enrolled in this study, including 288 patients in the XJ-procedure group, 132 patients in the continuous suture and pledgeted interrupted reinforcement group and 89 patients in the Bentall group. The 30-day mortality of all patients was 7.5% (38/509), and were 7.3%, 8.3% and 6.7% in the XJ-procedure group, continuous suture and pledgeted interrupted reinforcement group and Bentall group, respectively. The operation time of the XJ-procedure group [355 (320, 380) min] was significantly lower than the other two groups. The cardiopulmonary bypass time [154 (140, 169) min] and the aortic cross-clamping time [80 (72, 89) min] of XJ-procedure group were lower than the Bentall group [166 (147, 184) min and 86 (77, 96) min]. The aortic root bleeding that required secondary cardiopulmonary bypass did not occur in the XJ-procedure group. There was no significant difference in early postoperative complications among the three groups. The incidence of residual aortic root dissection before discharge, in 3 and 6 months after operation was lower in the XJ-procedure group compared to the continuous suture and pledgeted interrupted reinforcement group ( P<0.001). Conclusion:The XJ-procedure technique is a safe, simple and mastered method for the aortic root treatment of ATAAD, which shows an accurate early clinical effect.
