RESUMEN

The onset of inflammatory bowel disease (IBD) involves many factors, including environmental parameters, microorganisms, and the immune system. Although research on IBD continues to expand, the specific pathogenesis mechanism is still unclear. Protein modification refers to chemical modification after protein biosynthesis, also known as post-translational modification (PTM), which causes changes in the properties and functions of proteins. Since proteins can be modified in different ways, such as acetylation, methylation, and phosphorylation, the functions of proteins in different modified states will also be different. Transitions between different states of protein or changes in modification sites can regulate protein properties and functions. Such modifications like neddylation, sumoylation, glycosylation, and acetylation can activate or inhibit various signaling pathways (e.g., nuclear factor-‍κB (NF-‍κB), extracellular signal-regulated kinase (ERK), and protein kinase B (AKT)) by changing the intestinal flora, regulating immune cells, modulating the release of cytokines such as interleukin-1β (IL-‍‍1β), tumor necrosis factor-α (TNF‍-‍α), and interferon-‍γ (IFN-‍γ), and ultimately leading to the maintenance of the stability of the intestinal epithelial barrier. In this review, we focus on the current understanding of PTM and describe its regulatory role in the pathogenesis of IBD.

RESUMEN

Objective:To observe the effect of polyphyllin Ⅰ on the expressions of forkhead box Q1(FOXQ1)and epithelial-mesenchymal transition (EMT)-related factors, in order to explore the possible mechanism of polyphyllin Ⅰ in inhibiting the metastasis of colon cancer. Method:After the treatment with 1.25,2.50 μmol·L-1 polyphyllin Ⅰ on HCT116 cells, Western blot and Real-time PCR were used to detect the expressions of FOXQ1,E-cadherin,Vimentin protein and mRNA. Result:Compared with the blank group, relative expressions of FOXQ1 protein and mRNA in low-concentration polyphyllin Ⅰ group were decreased, while relative expression of E-cadherin mRNA was increased, the differences were not statistically significant, and relative expressions of Vimentin protein and mRNA in low-concentration polyphyllin Ⅰ group were decreased (P<0.05), and relative expression of E-cadherin protein in low-concentration polyphyllin Ⅰ group was increased (P<0.01). Compared with the blank group, relative expressions of FOXQ1, Vimentin protein and mRNA in high-concentration polyphyllin Ⅰ group were decreased,while relative expressions of E-cadherin protein and mRNA were increased (P<0.05, P<0.01). Compared with low-concentration polyphyllin Ⅰ group, relative expressions of Vimentin protein and mRNA in high-concentration polyphyllin Ⅰ group were decreased, but the difference was not statistically significant, relative expressions of E-cadherin protein and mRNA in high-concentration polyphyllin Ⅰ group were increased, whereas relative expressions of FOXQ1 protein and mRNA were decreased (P<0.05, P<0.01). Conclusion:Mechanism of polyphyllin Ⅰ inhibiting the metastasis of colon cancer may be related to the decrease of FOXQ1 and Vimentin expressions, and the up-regulation of E-cadherin.

RESUMEN

Objective:To observe the effect of Jianpi Xiaoai prescription on the activation of normal human embryonic lung fibroblasts (HFL1) into tumor-associated fibroblasts (CAFs) induced by human colon cancer cells (HCT116) derived exosomes. Method:SD rats were gavaged with 13.1 g·kg-1 of Jianpi Xiaoai prescription to prepare drug-containing serum, and HCT116 cell exosomes-containing 10% exosomes-free serum and 20% Jianpi Xiaoai prescription drug serum were isolated by ultra-high speed centrifugation. The particle size distribution of exosomes were detected by Nanoparticle tracking analyzer (Zetaview), and the exosomes' marker proteins apoptotic transfer gene 2 interaction protein X (Alix), heat shock protein 70 (HSP70), and tumor-susceptibility gene 101 (TSG101) were identified by Western blot, and the uptake of exosomes labeled with cell membrane staining kit (PKH67) by HFL1 was observed by fluorescence microscope. HFL1 cells were divided into six groups: the blank group, the transforming growth factor-β1 (TGF-β1) group, the TGF-β1 combined with HCT116 exosomes of 2 mg·L-1 group, the TGF-β1 combined with HCT116 exosomes of 4 mg·L-1 group, the TGF-β1 combined with Jianpi Xiaoai prescription exosomes of 2 mg·L-1 group, and the TGF-β1 combined with Jianpi Xiaoai prescription exosomes of 4 mg·L-1 group, and all groups were cultivated for 48 h. Western blot and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) were used to determine the protein and mRNA expressions of α-smooth muscle actin (α-SMA). Result:The particle size distribution detected by Zetaview was mainly between 50-100 nm, and the exosomes were verified based on the expressions of marker proteins Alix, HSP70 and TSG101. After co-incubation of HFL1 cells with exosomes, a large number of exosomes were absorbed by HFL1 cells under fluorescence microscope. Compared with the blank control group, the protein and mRNA expressions of α-SMA in the TGF-β1 group and TGF-β1 combined with HCT116 exosome groups were increased (P<0.01). Compared with the TGF-β1 combined with HCT116 exosome groups, the protein and mRNA expressions of α-SMA were decreased in the TGF-β1 combined with Jianpi Xiaoai prescription exosome groups (P<0.01). Conclusion:Human colon cancer cell exosomes combined with TGF-β1 can induce the activation of HFL1 into CAFs, and Jianpi Xiaoai prescription can reduce the activation of HFL1 by affecting the expressions of α-SMA, thus antagonizing the lung metastasis of colon cancer.

RESUMEN

<p><b>Background</b>Cervical cancer shows a growing incidence and medical cost in recent years that has increased severe financial pressure on patients and medical insurance institutions. This study aimed to investigate the medical economic characteristics of cervical cancer patients with different payment modes within a Grade A tertiary hospital to provide evidence and suggestions for inpatient cost control and to verify the application of Gamma model in medical cost analysis.</p><p><b>Methods</b>The basic and cost information of cervical cancer cases within a Grade A tertiary hospital in the year 2011-2016 were collected. The Gamma model was adopted to analyze the differences in each cost item between medical insured patient and uninsured patients. Meanwhile, the marginal means of different cost items were calculated to estimate the influence of payment modes toward different medical cost items among cervical cancer patients in the study.</p><p><b>Results:</b>A total of 1321 inpatients with cervical cancer between the 2011 and 2016 were collected through the medical records system. Of the 1321 cases, 65.9% accounted for medical insured patients and 34.1% were uninsured patients. The total inpatient medical expenditure of insured patients was RMB 29,509.1 Yuan and uninsured patients was RMB 22,114.3 Yuan, respectively. Payment modes, therapeutic options as well as the recurrence and metastasis of tumor toward the inpatient medical expenditures between the two groups were statistically significant. To the specifics, drug costs accounted for 37.7% and 33.8% of the total, surgery costs accounted for 21.5% and 25.5%, treatment costs accounted for 18.7% and 16.4%, whereas the costs of imaging and laboratory examinations accounted for 16.4% and 15.2% for the insured patient and uninsured patients, respectively. As the effects of covariates were controlled, the total hospitalization costs, drug costs, treatment costs as well as imaging and laboratory examination costs showed statistical significance. The total hospitalization costs, drug costs, treatment costs as well as imaging and laboratory examination costs of insured patient were 1.33, 1.42, 1.52, and 1.44 times of uninsured patients.</p><p><b>Conclusions</b>The analysis of different payment modes toward the medical economic characteristics based on Gamma model is basically rational. Medical payment modes are having certain influence toward the hospitalization expenses of cervical cancer patients in an extent, as drug costs, treatment costs, and examination costs appear to be the main causes.</p>

RESUMEN

PURPOSE: Vesicle-associated membrane protein 8 (VAMP8) is a soluble N-ethylmaleimide-sensitive factor receptor protein that participates in autophagy by directly regulating autophagosome membrane fusion and has been reported to be involved in tumor progression. Nevertheless, the expression and prognostic value of VAMP8 in breast cancer (BC) remain unknown. This study aimed to evaluate the clinical significance and biological function of VAMP8 in BC. METHODS: A total of 112 BC samples and 30 normal mammary gland samples were collected. The expression of VAMP8 was assessed in both BC tissues and normal mammary gland tissues via a two-step immunohistochemical detection method. RESULTS: The expression of VAMP8 in BC tissues was significantly higher than that in normal breast tissues. Furthermore, increased VAMP8 expression was significantly correlated with tumor size (p=0.007), lymph node metastasis (p=0.024) and recurrence (p=0.001). Patients with high VAMP8 expression had significantly lower cumulative recurrence-free survival and overall survival (p < 0.001 for both) than patients with low VAMP8 expression. In multivariate logistic regression and Cox regression analyses, lymph node metastasis and VAMP8 expression were independent prognostic factors for BC. CONCLUSION: VAMP8 is significantly upregulated in human BC tissues and can thus be a practical and potentially effective surrogate marker for survival in BC patients.

RESUMEN

Objective To develop a practical image acquisition strategy using intermittent breath?hold cone beam computed tomography (CBCT). Methods A breathing phantom was used to simulate the movement of tumor near the diaphragm during free breathing and breath hold and scanned by conventional breath?hold CBCT and type Ⅰ/Ⅱ intermittent breath?hold CBCT. In the conventional breath?hold CBCT, scan paused and free breathing occurred at the break of breath hold and free breathing was not included in the scan. In the intermittent breath?hold CBCT, one scan covered several breath holds separated by free breathing in a ratio of 3 vs1. Image quality and three?dimensional registration accuracy were quantitatively compared between conventional breath?hold CBCT and type Ⅰ/Ⅱ intermittent breath?hold CBCT. Comparison of image quality parameters between conventional breath?hold CBCT and intermittent breath?hold CBCT was made by paired t test. Results Motion artifacts arose in type I and Ⅱ intermittent breath?hold CBCT scans. There were no significant differences in the reconstructed pixel value or uniformity between intermittent breath?hold CBCT and conventional breath?hold CBCT ( P>0. 05, and P= 0. 02, 0. 53 ) . Compared with conventional breath?hold CBCT images, the signal?to?noise ratios of type I andⅡintermittent breath?hold CBCT images were reduced by 30% and 60%, respectively ( P<0. 05 ) . The registration error was up to 0 . 4 cm in the anterior?posterior direction and less than 0 . 1 cm in other directions . Conclusions The phantom study shows that intermittent breath?hold CBCT does not significantly reduce image quality or registration accuracy compared with conventional breath?hold CBCT. The feasibility of intermittent breath?hold CBCT in clinical application needs to be further validated among a large number of patients.

RESUMEN

Enhancer of rudimentary homolog (ERH) is a small, highly conserved protein among eukaryotes. Since its discovery nearly 20 years ago, its molecular function has remained enigmatic. It has been implicated to play a role in transcriptional regulation and in cell cycle. We recently showed that ERH binds to the Sm complex and is required for the mRNA splicing of the mitotic motor protein CENP-E. Furthermore, cancer cells driven by mutations in the KRAS oncogene are particularly sensitive to RNAi-mediated suppression of ERH function, and ERH expression is inversely correlated with survival in colorectal cancer patients whose tumors harbor KRAS mutation. These recent findings indicate that ERH plays an important role in cell cycle through its mRNA splicing activity and is critically required for genomic stability and cancer cell survival.
