ABSTRACT

Objective To screen the potential key genes of osteosarcoma by bioinformatics methods and analyze their immune infiltration patterns. Methods The gene expression profiles GSE16088 and GSE12865 associated with osteosarcoma were obtained from the Gene Expression Omnibus(GEO),and the differentially expressed genes(DEGs)related to osteosarcoma were screened by bioinformatics tools.Gene Ontology(GO)annotation,Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment,and analysis of immune cell infiltration were then carried out for the DEGs.The potential Hub genes of osteosarcoma were identified by protein-protein interaction network,and the expression of Hub genes in osteosarcoma and normal tissue samples was verified via the Cancer Genome Atlas(TCGA). Results A total of 108 DEGs were screened out.GO annotation and KEGG pathway enrichment revealed that the DEGs were mainly involved in integrin binding,extracellular matrix (ECM) structural components,ECM receptor interactions,and phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt)signaling pathway.Macrophages were the predominant infiltrating immune cells in osteosarcoma.Secreted phosphoprotein 1(SPP1),matrix metallopeptidase 2(MMP2),lysyl oxidase(LOX),collagen type V alpha(II)chain(COL5A2),and melanoma cell adhesion molecule(MCAM)presented differential expression between osteosarcoma and normal tissue samples(all P<0.05). Conclusions SPP1,MMP2,LOX,COL5A2,and MCAM are all up-regulated in osteosarcoma,which may serve as potential biomarkers of osteosarcoma.Macrophages are the key infiltrating immune cells in osteosarcoma,which may provide new perspectives for the treatment of osteosarcoma.

ABSTRACT

Platelet function tests have been increasingly used to assist in the diagnosis of platelet disorders and prethrombotic state, monitoring of the efficacy of antiplatelet therapies, and personalized treatment. On the basis of light transmission aggregometry, new methods for platelet function test have been developed successively. At present, the research and development of platelet function detector is in its infancy in China. The active constituents of antiplatelet Chinese medicines can be classified into terpenoids, flavonoids, saponins, organic acids, lignans, diketones, volatile oils, and stilbenes. The results of dose-antiplatelet effect relationship of Chinese medicines and the active constituents showed that the effective concentration of the extracts or monomers of Chinese medicines was at micromolar level(μmol·L~(-1)), among which salvianolic acid B and ginkgolide K, ginkgolide B, and ginkgolide A had the strongest antiplatelet effect. These results suggest that the antiplatelet effect of Chinese medicine may be weaker than that of chemical drugs and biological products. Therefore, it is necessary to explore the structure-activity relationship of the active constituents in existing Chinese medicines and further improve their efficacy through structure modification. The antiplatelet effect of Chinese medicines and the constituents involves multiple pathways and multiple targets. These research results provide a reference for clinical application of them. However, there is still a lack of large-scale multi-center clinical trials to confirm the efficacy and safety of them. The regularity of the relationship between the structures of various constituents and their corresponding functions is still unknown and the relevant signal transduction pathways and structure-activity relationship need to be further studied. This paper summarized and analyzed the determination methods of platelet functions and the research results of antiplatelet Chinese medicines, which is of reference value for the research of effective and safe antiplatelet Chinese medicines.

ABSTRACT

The aim of this paper was to explore the effect of Xueshuantong Injection(freeze-dried powder,XST) on κ-carrageenan-induced thrombosis and blood flow from the aspects of interactions among blood flow,vascular endothelium and platelets. Fifty male Sprague-Dawley rats(190-200 g) were randomized into five groups: control group, model group, heparin sodium(1 000 U·kg~(-1)) group, low-dose and high-dose(50, 150 mg·kg~(-1)) XST groups. Rats were intraperitoneally injected with corresponding drugs and normal saline(normal control and model groups) for 10 days. One hour after drugs were administered intraperitoneally on the 7 th day, each rat was injected with κ-carrageenan(Type Ⅰ, 1 mg·kg~(-1)) which was dissolved in physiological saline by intravenous administration in the tail to establish tail thrombus model. The lengths of black tails of the rats were measured at 2, 6, 24 and 48 h after modeling. Vevo®2100 small animal ultrasound imaging system was used to detect the internal diameter of rat common carotid artery, blood flow velocity and heart rate, and then the blood flow and shear rate were calculated. Meanwhile, the microcirculatory blood flow perfusion in the thigh surface and tail of rats were detected by laser speckle blood flow imaging system. Platelet aggregometry was used to detect the max platelet aggregation rate in rats. Pathological changes in tail were observed through hematoxylin-eosin staining, and Western blot was used to detect the protein content of platelet piezo1. According to the results, XST could inhibit the rat tail arterial thrombosis and significantly reduce the length of black tail(P<0.05). The blood flow of common carotid artery in XST low dose group was significantly higher than that in the model group(P<0.05). XST high dose group could significantly increase the microcirculatory blood flow perfusion of the tail in rats as compared with the model group(P<0.05). XST high dose group could significantly inhibit platelet aggregation rate(P<0.05) and XST low dose group could significantly inhibit platelet piezo1 protein expression(P<0.01). In summary, XST could play an effect in fighting against thrombosis induced by κ-carrageenan in rats, which may be related to significantly inhibiting platelet aggregation, improving body's blood flow state, maintaining normal hemodynamic environment and affecting mechanical ion channel protein piezo1.

ABSTRACT

@#[Abstract] Objective: To investigate the expression of chemokine-like factor-like MARVEL transmembrane domain-containing family member 6 (CMTM6) in breast cancer tissues and its correlation with clinicopathological features and prognosis of patients. Methods:Atotal of 136 breast cancer tissue chips (purchased from Superchip Company), including 42 pairs of matched cancer and paracancerous tissues, were used for this study. The expression level of CMTM6 in cancer and paracancerous tissues was detected by immunohistochemistry. The comparison of CMTM6 expression between breast cancer and paracancerous tissues was conducted by paired χ2 test. The relationship between CMTM6 expression in breast cancer tissues and the clinicopathological characteristics of patients was analyzed by χ2 test. Kaplan-Meier and Log rank test analyses were used to analyze the relationship between CMTM6 expression and the survival of patients, and Cox model was used to evaluate the effect of different indicators on the prognosis of patients. Results: The expression of CMTM6 in breast cancer tissues was significantly higher than that in paracancerous tissues (P<0.01). The expression of CMTM6 was correlated with pathological type of breast cancer and HER2 positivity (P<0.05). The survival time of patients in CMTM6 high expression group was significantly shorter than that of patients in CMTM6 low expression group (P<0.05). Pathological type (HR=10.374, 95%CI: 3.529-30.497, P<0.01), TNM stage (HR=4.599, 95%CI: 1.784-11.856, P<0.01), triple-negative breast cancer (HR=3.370, 95%CI: 1.055-10.761, P<0.05) and high expression of CMTM6 (HR=0.195, 95%CI: 0.073-0.518, P<0.01) were independent risk factors for prognosis of breast cancer patients. Conclusion: CMTM6 is highly expressed in breast cancer tissues, which can be used as a risk factor for prognosis evaluation of breast cancer patients.

ABSTRACT

@#Objective: To investigate the regulatory effect of lncRNA MALAT1/miR-141-3p/ZEB1 axis on the invasion, metastasis and epithelial mesenchymal transition (EMT) of gastric cancer (GC) cells. Methods: Thirty-eight pairs of GC tissues (non-necrotic part) and corresponding adjacent tissues (>5 cm away from tumor tissue) removed by general surgery in Wuhan Commercial Hospital from April 2014 to May 2017 were collected. Meanwhile, normal gastric epithelial GES1 cells and GC cell lines (SGC7901, HGC27, BGC823, MKN45 and MKN28) were selected. The expression level of MALAT1 and miR-141-3p in GC tissues and cell lines were detected by qPCR. The effect of MALAT1 knockdown on proliferation, migration and invasion of SGC7901 cells was determined by CCK-8 assay and Transwell assay. WB was performed for measuring the expression level of ZEB1, E-cadherin, N-cadherin and Vimentin. Dual luciferase reporter gene assay was used to validate the relationship among MALAT1, miR-141-3p and ZEB1. CCK-8 assay and Transwell assay were used to detect the effect of MALAT1/miR-141-3p/ZEB1 axis on biological behaviors of SGC7901 cells. Results: MALAT1 was over-expressed in GC tissues and cell lines (P<0.05 or P<0.01). Knockdown of MALAT1 significantly inhibited the proliferation, migration, invasion and EMT of SGC7901 cells (P<0.05 or P<0.01). The results of dual luciferase reporter gene assay showed that MALAT1 directly targeted miR-141-3p, as well as for miR-141-3p and ZEB1. Further experiment indicated that simultaneous over-expression of miR-141-3p and MALAT1 or ZEB1 could restore the biological behaviors of SGC7901 cells, which were inhibited by miR-141-3p. Conclusion: MALAT1 promotes the invasion, metastasis and EMT of GC SGC7901 cells by down-regulating the inhibitory effect of miR-141-3p on ZEB1.

This meta-analysis aimed to comprehensively assess the efficacy and safety of hepatic resection combined with radiofrequency ablation versus hepatic resection (HR) alone for the treatment of multifocal hepatoeellular carcinomas (HCC).A literature search was conducted from the database including MEDLINE,Embase,Cochrane Central Register of Controlled Trials (CENTRAL) and China Biology Medicine (CBM) disc.The primary outcomes included the 1-,3-,5-year overall survival (OS) and disease-free survival (DFS) rate.The secondary outcomes contained the intraoperative parameters and postoperative adverse events (AEs).These parameters were all analyzed by RevMan 5.3 software.After carefully screening relevant studies,four retrospective studies of high quality involving 466 patients (197 in the combined group and 269 in the HR group) were included in this study.The pooled results showed that the 1-,3-,5-year OS rate in the combined group were comparable with those in the HR group (OR=0.77,0.96,0.88;P=0.33,0.88,0.70,respectively).Similarly,there was no significant difference in 1-,3-,5-year DFS rate between the combined group and the HR alone group (OR=0.57,0.83,0.72;P=0.17,0.37,0.32,respectively).And the intraoperative parameters and postoperative AEs were also comparable between the above two cohorts.However,two included studies reported that tumor often recurred in the ablation site in the combined group.The present meta-analysis indicated that the HR combined with RFA could reach a long-term survival outcome similar to curative HR for multifocal HCC patients.And this therapy may be a promising alternative for these patients with marginal liver function or complicated tumor distribution.Furthermore,high quality randomized controlled trials (RCTs) are imperative to verify this conclusion.

ABSTRACT

SUMMARY Resistance to thyroid hormone (RTH) coexisting with ectopic thyroid is rare. Here we report a case of RTH with ectopic thyroid. A ten-year-old girl had been misdiagnosed as congenital hypothyroidism and treated with levothyroxine since she was born. Ten-year follow-up showed that the elevated thyrotropin was never suppressed by levothyroxine and no signs indicating hyperthyroidism or hypothyroidism despite elevated FT3 and FT4 levels. Therefore the girl developed no defects in physical and cognitive development. Pituitary adenoma was excluded by magnetic resonance imaging. Ultrasonography did not find the thyroid gland in the normal place, while the thyroid scan found a large lingual thyroid gland. The octreotide inhibition test showed a reduction in thyrotropin by 41.98%. No mutation was detected in the thyroid hormone receptor (THR) β, THRα, thyrotropin receptor (TSHR), and GNAS1 genes. To our knowledge, it is an interesting RTH case coexisting with lingual thyroid.

ABSTRACT

ABSTRACT Objective: Studies have indicated that AMPK play critical roles in the regulation of innate immunity and inflammatory responses. However, the role of the polymorphisms of PRKAA1 gene in immune-response to infectious organisms remains unknown. To evaluate the potential role of PRKAA1/AMPKα1 in the immune-response to HBV, we conducted this case-control study. Methods: We recruited 276 patients (145 men and 131 women; average age, 51.6 years) with chronic HBV infection (CHB) and 303 healthy controls (166 men and 137 women; average age, 54.2 years). All the subjects were unrelated individuals of Chinese Han Population. Three SNPs of PRKAA1gene were tested. Results: Rs1002424 polymorphism showed significant difference in the allele frequencies, but no difference in the genotype frequencies (allele: p = 0.039411, OR95%CI = 0.783479 [0.621067-0.988362]; genotype: p = 0.104758); rs13361707 polymorphism showed significance in allele analysis, but not in genotype analysis (allele: p = 0.034749, OR95%CI = 1.284303 [1.017958-1.620335]; genotype: p = 0.098027); rs3792822 polymorphism was demonstrated to have significant differences in both genotype and allele frequencies between cases and controls (allele: p = 0.029286, OR95%CI= 0.741519 [0.566439-0.970716]; genotype: p = 0.034560). The haplotype results showed that CTG and TCA in the rs13361707-rs1002424-rs3792822 block were significantly associated with the happening of HBV (CTG: p = 0.036854, OR95%CI = 1.281 [1.015-1.617]; p = 0.030841, OR95%CI = 0.743 [0.568-0.973]). Conclusion: These findings suggest that PRKAA1 polymorphisms may contribute to the susceptibility of chronic HBV infection in Chinese Han origin.
