RESUMEN
ObjectiveTo investigate the expression of Midkine （MDK） in cholangiocarcinoma （CCA） and its value in predicting the prognosis of CCA， as well as the potential mechanism of the effect of MDK on the progression of CCA. MethodsThe data of CCA samples were obtained from TCGA database to analyze the difference in the expression of MDK between cancer tissue and paracancerous tissue and its association with clinical features， and the data collected from GEO database and 11 CCA patients who underwent surgical resection in The Fifth Medical Center of Chinese PLA General Hospital from June 2018 to September 2021 were used for validation. STRING and Cytoscape were used to construct a protein-protein interaction network， and gene ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analyses were used to investigate the biological functions and tumor-related pathways involving MDK-related genes. In addition， TIMER and TISIDB databases were used to analyze the correlation between MDK expression and immune cell infiltration in CCA tissue. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the Fisher’s exact test was used for comparison of categorical data between two groups. The Kaplan-Meier method was used to plot survival curves， and the Log-rank test was used for comparison between groups. The Spearman correlation analysis was used to investigate the correlation between two variables. ResultsThe expression level of MDK in cancer tissue and paracancerous tissue of CCA patients was compared based on TCGA database， and the results of the non-paired and paired analyses showed that the expression level of MDK in CCA tumor tissue was significantly higher than that in paracancerous tissue （P<0.001）. Transcriptome sequencing was performed for the tumor tissue and its corresponding paracancerous tissue from 11 CCA patients， and the results showed that the expression level of MDK in CCA tumor tissue was significantly higher than that in corresponding paracancerous tissue （P<0.01）. High expression of MDK was associated with lymph node metastasis （P=0.045） and vascular invasion （P=0.044）. Survival analysis showed that compared with the CCA patients with low MDK expression， the CCA patients with high MDK expression had significantly shorter overall survival time （χ2=5.30， P=0.028） and disease-specific survival time （χ2=6.25， P=0.019）. The GO and KEGG enrichment analyses showed that the 30 MDK-related genes were closely associated with ubiquitin-mediated proteolysis and affected the prognosis of CCA patients. The TIMER analysis showed that the expression level of MDK was positively correlated with the infiltration of B cells （r=0.356， P=0.035 6） and dendritic cells （r=0.409， P=0.014 7） in tumor microenvironment of CCA； the TISIDB analysis showed that the expression level of MDK was positively correlated with CXCL16 （r=0.465， P=0.004 67） and was negatively correlated with CXCL12 （r=-0.389， P=0.019 7） and CXCR5 （r=-0.393， P=0.018 5）， and it was also negatively correlated with the immune checkpoint regulators VTCN1 （r=-0.393， P=0.018 3）， LTA （r=-0.380， P=0.022 7）， and PVR （r=-0.350， P=0.037 3）. ConclusionHigh expression of MDK is associated with poor prognosis in CCA patients， and MDK has the potential of being used as a molecular marker for predicting the prognosis of CCA. MDK may promote the development and progression of CCA by regulating ubiquitin-mediated proteolysis and the infiltration of B cells and dendritic cells.
RESUMEN
Objective:Based on the National Patent Database, this paper analyzes the medication rule of Traditional Chinese Medicine (TCM) compound patents for the treatment of colorectal cancer in the past 10 years.Methods:By searching for and extracted screening out TCM compound patents for the treatment of colorectal cancer and after the dada selection, data entry , data specifications, the compound patents database for the treatment of colorectal cancer was established. then used IBM SPSS Modeler and IBM SPSS Statistics software to perform frequency analysis, attribute analysis, association analysis and cluster analysis of TCM.Results:A total of 97 compound patents were included, including 411 TCM, among which the core medicines are Atractylodis macrocephalae rhizoma, Hedyotis diffusa, Astragali radix, Glycyrrhizae radix et rhizoma, Scutellariae barbatae herba, Poria, etc. The medicine is mainly cold and warm; The medicine mainly tastes bitter and sweet; The spleen meridian is the main meridian. The cluster analysis result shows there are 7 categories, and the paired TCM with strong correlation includes Hedyotis diffusa- Scutellariae barbatae herba, Atractylodis macrocephalae rhizoma- Curcumae rhizoma, Astragali radix- Codonopsis radix and so on. Conclusions:Treating colorectal cancer should take those medicine which could invigorate the spleen and nurture the deficiency, such as Atractylodis macrocephalae rhizoma, Astragali radix, Codonopsis radix, while for clearing away heat, detoxifying, promoting blood circulation and removing blood stasis, such as Hedyotis diffusa, Scutellariae barbatae herba, and Curcumae rhizoma. At the same time, it can be combined as appropriate, attacking and replenishing simultaneously, regulating qi and blood.
RESUMEN
Objective To explore the application value of ultrasound in the diagnosis and treatment for cesarean scar pregnancy. Method The ultrasonic features, clinical treatment of 42 cases of cesarean scar pregnancy were reviewed retrospectively. Results Among 42 patients,35 patients (83.3% ,35/42) were diagnosed accurately by ultrasound. The sonographic appearance showed 15 cases were gestational sac-type and 22 cases were mixed mass-type,the other 5 cases were classified into type three in which the gestational sac mostly located at the uterine cavity and only the inferior part implanted in the cesarean scar. Uterine artery embolisation and suction curettage with the sonographic guidance with 2 cases, intra-amniotic administration of MTX under sonographic guidance with 15 cases, expectant treatment with 20 cases or complex treatment with 5 cases. During treatment,ultrasonography showed focus of infection was shrinked gradually and blood flow disappeared, blood (3 -human chorionic gonadotrophin was decreased to normal level. ConclusionUltrasound can diagnose cesarean scar pregnancy promptly and accurately, proportionate treatment would be selected according to the type of cesarean scar pregnancy, and also can evaluate the therapeutic effect.
