    Objective: To study the expression level, prognosis and correlation with immune cell infiltration of BUB1B in pancreatic adenocarcinoma ( PAAD ) by online database and bioinformatics. Methods: The expression of BUB1B in various cancers was analyzed by GEPIA database. The correlation between the expression of BUB1B and the prognosis of PAAD patients was searched by GEPIA and Kaplan-Meier Plotter database. Then, the protein interaction network of BUB1B co-expressed genes was constructed by using String database, and its GO biological function and KEGG signaling pathway were analyzed by using David database. Finally, the TIMER database was used to analyze the correlation between the expression of BUB1B gene and immune cell infiltrating cells. Results: The expression level of BUB1B in PADD tissues was higher than that in normal tissues (P＜0.01). The high transcription level of BUB1B was closely related to gender, age, race, obesity, drinking habits, chronic pancreatitis, lymph node metastasis and cancer stage (P＜0.05). The expression level of BUB1B mRNA was associated with prognosis and immune cell infiltration (P＜0.05). Conclusion: BUB1B is highly expressed in PADD, which is related to prognosis and immune infiltration, and can be used as a potential marker for diagnosis, prognosis and drug treatment of pancreatic cancer.

    Objective: To investigate the expression of miR-17-5p in lung adenocarcinoma cells, and to study the effects of miR-17-5p on proliferation, invasion, migration and apoptosis of lung adenocarcinoma cells and its molecular mechanism. Methods: The expression of miR-17-5p in human lung adenocarcinoma cell line HCC827 and human normal lung epithelial cell line BEAS-2B were detected by real-time fluorescent quantitative PCR. There were miR-17-5p mimics group, miR-17-5p inhibitor group and NC group in the experiment. The effects of miR-17-5p on proliferation, apoptosis, invasion and migration of lung adenocarcinoma cells were analyzed by CCK-8, flow cytometry and Transwell assay. Finally, PKD2 was predicted to be a potential downstream target gene of miR-17-5p by Targetscan database. The interaction between miR-17-5p and PKD2 was verified by real-time fluorescence quantitative PCR and Western-blot experiments. Results: miR-17-5p was highly expressed in HCC827 cells (P＜0.001), and up-regulation of miR-17-5p significantly promoted the proliferation (P＜0.05 ), invasion (P＜0.01 ) and migration (P＜0.05) of lung adenocarcinoma cells, and inhibited apoptosis (P＜0.01 ). There was a direct binding site between miR-17-5p and 3'UTR of PKD2, and overexpression of miR-17-5p significantly promoted the expression of PKD2 at both mRNA and protein levels (P＜0.01). Conclusion: PKD2 was the direct target gene of miR-17-5p, and miR-17-5p affected the biological behavior of lung adenocarcinoma cells by regulating PKD2.

    Objective: To measure and analyze the anatomical parameters of the femur by measuring and analyzing the positive and lateral X-ray films of the full-length weight-bearing lower limbs and the three-dimensional model of the femur CT, and to clarify the correlation between the anatomical morphology of the femur and the sagittal force line, so as to provide help for the placement of knee prosthesis and the accurate recovery of the lower limb force line in total knee arthroplasty. Methods: Ten healthy volunteers were recruited. The full-length X-ray films of the lower limbs were taken to determine the coronal and sagittal force lines of the lower limbs and the weight-bearing ratio. The imaging data of 60 patients with full-length CTA of both lower limbs were collected. The CT data were reconstructed by Mimics software. The relevant anatomical parameters were measured by combining two-dimensional images and three-dimensional reconstruction models. The data were analyzed by K-S test. Results: (1)The standard weight-bearing positive bearing axis is located at 45% of the medial femoral condyle, and the lateral bearing axis is located at 44% before the transverse axis of the femoral condyle. (2) The femoral three-dimensional model measured femoral valgus angle, femoral lateral arch angle, femoral anterior arch angle, proximal femoral eccentricity, femoral neck anteversion, femoral neck shaft angle, and femoral length were 4.55°±1.31°, 0.41°±1.44°, 9.54°±1.57°, 37.04±4.74 mm, 14.99° ±7.52°, 131.17±7.23 °, and 414.24±23.70 mm, respectively; the angles between the femoral anatomical axis and the coronal and sagittal planes were 8.60±1.45, 0.75±0.60, 1.05±0.70 and 0.61±0.50, respectively; the angles between the femoral force line and the coronal and sagittal planes were 1.38°±0.93° and 4.77°±1.65°, respectively. (3)Correlation analysis showed that the femoral valgus angle was positively correlated with the femoral lateral arch angle (r=0.552, P＜0.001), the femoral valgus angle was positively correlated with the proximal femoral eccentricity (r=0.502, P＜0.001), and the femoral anterior arch angle was positively correlated with the femoral neck anteversion angle (r=0.543, P＜0.001); the angle between the femoral force line and the sagittal plane was positively correlated with the femoral anterior arch angle (r=0.823, P＜0.001), and the angle between the femoral force line and the sagittal plane was positively correlated with the femoral neck anteversion angle (r=0.424, P＜0.001). Conclusion: The angle between the femoral force line and the sagittal plane is closely related to the femoral anterior arch angle and the femoral neck anteversion angle. Therefore, if the femoral anterior arch angle and the femoral neck anteversion angle are larger before operation, the osteotomy angle should be adjusted accordingly, which is conducive to achieving a more reasonable alignment of the force line. The correlation between the anatomical morphology of the femur and the sagittal alignment of the femur described in this study has important reference significance for the placement of knee prosthesis and total knee arthroplasty.

    Objective: To explore the application value of artificial intelligence (AI) in quantitative evaluation of CT images of different clinical types of COVID-19. Methods: A total of 169 patients with COVID-19 who underwent chest CT examination between October 2021 and June 2022 were included in the study, and were divided into a severe group of 14 cases and a non-severe group of 155 cases. The general data and imaging information of the COVID-19 patients were collected and analyzed retrospectively. The lesion volume fraction, GGO volume fraction, consolidation volume fraction, GGO + consolidation volume fraction and crazy-paving pattern volume fraction were measured and calculated with the assistance of the “AI qualitative auxiliary diagnosis system for CT images of COVID-19” provided by BIOMIND. Mann-whitney U test was used to compare the data of the two groups. The receiver operating characteristic curve (ROC) was used to evaluate the diagnostic efficacy of the above indexes in severe patients. Results: There were significant differences in lesion volume fraction and GGO volume fraction between the two groups (P＜0.05). However, there was no significant difference in the volume fraction of consolidation, GGO + consolidation and crazy-paving pattern (P＞0.05). The sensitivity of lesion volume fraction and GGO volume fraction for clinical classification of COVID-19 was 1 and 0.6, and the specificity was 0.822 and 0.923, respectively. Conclusion: The lesion volume fraction and GGO volume fraction calculated with the assistance of AI are sensitive indicators for clinical classification of COVID-19.

    Objective: To investigate the predictive value of serum lipoprotein (a) [Lp(a)] and high-sensitivity C-reactive protein/high-density lipoprotein ratio (CHR) for short-term prognosis in patients with acute myocardial infarction (AMI). Methods: A total of 251 patients with AMI who underwent percutaneous coronary intervention in the Department of Cardiology of Baotou Central Hospital from July 2021 to July 2022 were selected for retrospective analysis. The general data, laboratory indexes, killip classification, ejection fraction (EF value) and coronary angiography results of the enrolled patients were collected. The CHR value and Gensini score were calculated according to the laboratory indexes and coronary angiography results. According to whether major adverse cardiovascular events (MACE) occurred during hospitalization of AMI patients, they were divided into observation group and control group. The differences of general data and laboratory indexes between the two groups were compared. Univariate and multivariate logistic regression were used to analyze the influencing factors of MACE in AMI patients during hospitalization. The receiver operating characteristic (ROC) curve was used to analyze the predictive value of Lp(a), CHR and Lp(a) combined detection of CHR for MACE. Results: The Lp(a), CHR, killip grade≥II and Gensini score in the observation group were higher than those in the control group, and the differences were statistically significant (P＜0.05). Lp (a) and CHR were independent risk factors for MACE in patients with AMI during hospitalization. ROC curve showed that the combined detection of Lp(a), CHR and Lp(a) CHR had predictive value for MACE in AMI patients during hospitalization, and the combined detection value was higher. Conclusion: Lp(a) and CHR are independent risk factors for MACE in AMI patients during hospitalization. Combined detection of Lp(a) and CHR is helpful to evaluate the short-term prognosis of AMI patients.

Methods: Patients who were diagnosed as OVCF and treated with PKP by the same surgical team in the Third Hospital of Baotou from June 2018 to June 2022 were selected. The blood routine, blood biochemical indexes and basic information of the patients at admission were collected, and the postoperative survival and Oswestry dysfunction index (ODI) questionnaire were followed up. According to whether the patients survived during the follow-up period, the patients were divided into survival group and death group. The related examination indexes of the two groups of patients at admission were compared, and the influencing factors of the death outcome of the patients were analyzed. Results: The 1-year mortality rate of 176 patients with OVCF was 6.81% (12/176), and the total mortality rate was 18.75% (33/176) during the follow-up period. The AUC of bone mineral density (BMD) in predicting death was 0.797 (95%CI: 0.699-0.895, P＜0.05), when the sensitivity was 66.7% and the specificity was 85.3%, the maximum diagnostic index was 0.520, and the diagnostic cut-off point was -3.430. The AUC of albumin (ALB) in predicting death was 0.676 (95%CI: 0.572-0.780, P＜0.05), when the sensitivity was 63.6% and the specificity was 70.6%, the diagnostic index was 0.342, and the diagnostic cut-off point was 39.450 g/L. The AUC of neutrophil-to-lymphocyte ratio (NLR) in predicting death was 0.786 (95%CI: 0.693-0.879, P＜0.05), when the sensitivity was 81.8% and the specificity was 65.0%, the diagnostic index was 0.468, and the diagnostic cut-off point was 3.120. The AUC of BMD, ALB and NLR combined to predict the death of patients was 0.871 (95%CI: 0.798-0.945, P＜0.05). When the sensitivity was 75.8% and the specificity was 86.7%, the maximum diagnostic index was 0.625, and the diagnostic cut-off point was 4.945, which was higher than the area under the curve of NLR, BMD and ALB.

    Objective: To explore the diagnostic and prognostic value of FAM25A in pancreatic cancer by bioinformatics methods, analyze its correlation with immune infiltration, and elaborate the potential mechanism of FAM25A in the occurrence and development of pancreatic cancer. Methods: The Pancreatic cancer datasets were obtained from TCGA, GTEx and GEO databases, and Rstudio was used for data analysis and visualization. The expression difference of FAM25A was clarified. The relationship between the expression of FAM25A and the overall survival time of pancreatic cancer was analyzed by K-M. The correlation between FAM25 A expression and prognostic factors of pancreatic cancer was analyzed by Cox regression. The correlation between FAM25A expression and immune cell infiltration was analyzed. According to WGCNA, the module genes most related to FAM25A and tumor purity were imported into STRING to construct PPI network and obtain GO and KEGG. GSEA was used to analyze the enrichment pathway of high and low expression of FAM25A, and MOCDE clustering subnetwork in Cytoscape was used to obtain significantly related nodes. Based on the above information, the potential mechanism of FAM25A in pancreatic cancer was analyzed. Results: The results showed that FAM25A was significantly more highly expressed in pancreatic cancer (P＜0.01); K-M analysis showed that the survival time of patients with high expression of FAM25 A was significantly shorter than that of patients with low expression; Cox regression analysis of prognostic factors related to pancreatic cancer suggested that FAM25A was an independent risk factor for pancreatic cancer (HR=2.4, 95%CI=1.614-3.592); Correlation analysis of immune cell infiltration showed that FAM25A could reduce T lymphocyte level; GO, KEGG, GSEA and MCODE results showed that FAM25A mainly played a role in cell-cell interaction, intercellular signal generation and transduction, chemokine and immune response. Conclusion: FAM25A over-expression in pancreatic cancer is an independent poor prognostic factor in pancreatic cancer. Abnormal expression of FAM25A can also be used as bio-markers for diagnosis and prognosis of pancreatic cancer. Its biological effects may be achieved by promoting proliferation, invasion and metastasis of pancreatic cancer.

The index values of five classification webs in the intervention group were significantly higher than those in the conventional group (P＜0.05). The conversion rate of sputum culture in the intervention group was significantly higher than that in the conventional group (P＜0.05). The CT cavity closure rate in the intervention group was significantly higher than that in the conventional group (P＜0.05). Conclusion: Combined intervention can effectively improve patients' medication compliance and treatment effect, and promote patients' recovery.

    Abnormal DNA methylation is one of the important mechanisms of tumorigenesis and development. It is the core of establishing and maintaining tissue-specific gene expression, and also the mechanism of regulating gene expression, which plays an important role in tumorigenesis. In particular, the abnormal state of hypermethylation of tumor suppressor genes is of great significance in the occurrence, diagnosis, identification, prognosis and treatment of tumors. In addition, DNA methylation and demethylation are reversible processes. 5-Azacytidine can reduce the methylation level of hypermethylated tumor suppressor genes by inhibiting DNA methyltransferase, so as to achieve the goal of tumor treatment. In leukemia, myelodysplastic syndrome, precursor bone marrow cell tumors and solid tumors, 5-azacytidine inhibits cell proliferation and promotes cell differentiation through DNA demethylation, which has therapeutic potential. However, its low bioavailability and long-term use may cause DNA damage and cytotoxicity. Therefore, it is necessary to find better administration methods and dose regulation strategies to verify and optimize its anti-tumor efficacy and promote clinical application.

    Schisandra chinensis is a kind of medicinal plant with important medicinal value and economic value in China. Endophytic fungi, endophytic bacteria and endophytic actinomycetes are the main components of endophyte of Schisandra chinensis. The endophyte of Schisandra chinensis can produce the same or similar active metabolites as the plants, such as lignans, triterpenes, organic acids and other active substances. With the continuous progress of scientific exploration, the role of endophytes in anti-bacterial, anti-cancer, anti-oxidation and biological control of pathogenic bacteria has been gradually discovered, which has become the focus of industry, medicine, agriculture and other related fields. In this paper, the research on the biological activity of endophytes and secondary metabolites of Schisandra chinensis at home and abroad in recent years is reviewed, which provides theoretical support for the development and application of secondary metabolites of endophytes of Schisandra chinensis.
