RESUMO

Circular RNAs (circRNAs) have been found to be involved in the progression of acute pancreatitis (AP). The objective of our study was to investigate the effects of circ_0000284 on caerulein-induced AR42J cell injury. To mimic AP in vitro, rat pancreatic acinar AR42J cells were treated with caerulein. The expression of circ_0000284 and miR-10a-5p was evaluated by quantitative real-time polymerase chain reaction (qRT-PCR). Enzyme-linked immunosorbent assay (ELISA) was employed to determine the content of inflammatory cytokines interleukin (IL)-1ß, IL-6, IL-8 and tumor necrosis factor α (TNF-α). Western blotting was applied to analyze the levels of Wnt/ß-catenin pathway-related and apoptosis-related proteins. Cell viability and apoptosis were monitored by Counting Kit-8 (CCK-8) assay and flow cytometry, respectively. The target connection between circ_0000284 and miR-10a-5p was verified by dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay. AP induced inflammation in patients, and caerulein treatment increased apoptosis and inflammation in AR42J cells. Circ_0000284 was upregulated in serum of AP patients and caerulein-induced AR42J cells, while Wnt/ß-catenin pathway was inactivated. Knockdown of circ_0000284 could decrease apoptosis and inflammation in caerulein-induced AR42J cells, which was attenuated by miR-10a-5p inhibition or Wnt signaling pathway antagonist Dickkopf-related protein 1 (DKK1). MiR-10a-5p was sponged by circ_000028 and was downregulated in caerulein-induced AR42J cells. Circ_0000284 depletion could protect caerulein-induced AR42J cells from apoptosis and inflammation by upregulating miR-10a-5p expression and activating Wnt/ß-catenin pathway, underscoring a potential target for AP therapy.

RESUMO

ABSTRACT Introduction: The set of muscles in the lumbo-pelvic-hip complex is called the core. The core is located in the body's center of gravity. Dancesport require aligned trunk movements and permanent stabilization between the spine and pelvis. Despite few studies, the relationship between unbalanced core strengthening and injuries in dancesport is investigated. Objective: Study the relationship between unbalanced core strengthening and muscle strength in dancesport athletes. Methods: An experiment was conducted with 60 students from dance schools. They were randomly divided between an experimental group and a control group, with 30 people each. Each group included 15 males and 15 females. The experimental group used unilateral core stability training. The control group used traditional core stability training. Results: The results showed that the quality of action improved significantly after core strength training (P <0.05), but there was no significant difference between the two groups. Conclusions: Core strengthening can improve balance ability in athletes. There was no statistical difference between the training, with similar positive balance ability and explosion strength effects in the athletes. Level of evidence II; Therapeutic studies - investigation of treatment results.

RESUMO

Purpose: Hepatitis B (HBV)-infected hepatocellular carcinoma is one of the most common cancers, and it has high incidence and mortality rates worldwide. The incidence of hepatocellular carcinoma has been increasing in recent years, and existing treatment modalities do not significantly improve prognosis. Therefore, it is important to find a biomarker that can accurately predict prognosis. Methods: This study was analyzed using the The Cancer Genome Atlas (TCGA) database and validated by the International Cancer Genome Consortium (ICGC) database. The STRING database was used to construct a gene co-expression network and visualize its functional clustering using Cytoscape. A prognostic signature model was constructed to observe high and low risk with prognosis, and independent prognostic factors for HBV-infected hepatocellular carcinoma were identified by Cox regression analysis. The independent prognostic factors were then analyzed for expression and survival, and their pathway enrichment was analyzed using gene set enrichment analysis (GSEA). Results: 805 differentially expressed genes (DEGs) were obtained by differential analysis. Protein-protein interaction (PPI) showed that DEGs were mostly clustered in functional modules, such as cellular matrix response, cell differentiation, and tissue development. Prognostic characterization models showed that the high-risk group was associated with poor prognosis, while Cox regression analysis identified ASF1B as the only independent prognostic factor. As verified by expression and prognosis, ASF1B was highly expressed in HBV-infected hepatocellular carcinoma and led to a poor prognosis. GSEA showed that high ASF1B expression was involved in cell cycle-related signaling pathways. Conclusion: Bioinformatic analysis identified ASF1B as an independent prognostic factor in HBV-infected hepatocellular carcinoma, and its high expression led to a poor prognosis. Furthermore, it may promote hepatocellular carcinoma progression by affecting cell cycle-related signaling pathways.

RESUMO

Background: The potential functions of Thrombospondin 2 (THBS2) in the progression and immune infiltration of gastric cancer (GC) remain unclear. The purpose of this study was to clarify the role of THBS2 in GC prognosis and the relationship between THBS2 and GC immune cell infiltration. Material and Methods: The differential expression levels of THBS2 in the GC and cancer-adjacent tissues were identified using the TCGA databases and verified using real-time polymerase chain reaction (PCR), immunohistochemical staining and two datasets from Gene Expression Omnibus (GEO). THBS2 related differential expressed genes (DEGs) were identified and used for further functional enrichment analysis and Gene Set Enrichment Analysis (GSEA). Furthermore, a THBS2-related immune infiltration analysis was also performed. Kaplan-Meier and Cox regression analyses were utilized to illustrate the effects of THBS2 on the prognosis and clinical variables of GC. Finally, a nomogram was constructed to predict the survival probability of patients with GC. Results: The THBS2 expression in GC was significantly higher than that in cancer-adjacent tissues (p < 0.001), which was verified using real-time PCR, immunohistochemical staining and datasets from GEO. The 599 identified DEGs were primarily enriched in pathways related to tumorigenesis and tumor progression, including the focal adhesion pathway, signaling by vascular endothelial growth factor, and Wnt signaling. THBS2 expression was positively correlated with the enrichment of the macrophages (r = 0.590, p < 0.001), which was also confirmed by immunohistochemistry; however, negatively correlated with the enrichment of Th17 cells (r = 0.260, p < 0.001). The high expression of THBS2 was significantly correlated with the pathological grade (p < 0.01), histological grade (p < 0.05), histological type (p < 0.05), T stage (p < 0.001), and poor overall survival (OS) (P = 0.003) of GC. The constructed nomogram can well predict the 1-, 3-, and 5-years OS probability of patients with GC (C-index [95% confidence interval] = 0.725 [0.701-0.750]). Conclusion: THBS2 is closely related to the poor prognosis and immune infiltration of gastric cancer.

RESUMO

Background: Biglycan (BGN) plays a role in the occurrence and progression of several malignant tumors, though its role in gastric cancer (GC) remains unclear. The objective of this study was to investigate BGN expression, its role in GC prognosis, and immune infiltration. Material and Methods: Gene expression data and corresponding clinical information were downloaded from TCGA and GTEx, respectively. We compared the expression of BGN in GC and normal tissues and verified the differential expression via Real-Time PCR and immunohistochemistry. BGN-related differentially expressed genes (DEGs) were identified. Additionally, the relationships between BGN gene expression and clinicopathological variables and survival in patients with GC were also investigated through univariate and multivariate Cox regression analyses. Finally, we established a predictive model that could well predict the probability of 1-, 3-, and 5-years survival in GC. Results: We found a significantly higher expression of BGN in GC than that in normal tissues (p < 0.001), which was verified by Real-Time PCR (p < 0.01) and immunohistochemistry (p < 0.001). The 492 identified DEGs were primarily enriched in pathways related to tumor genesis and metastasis, including extracellular matrix (ECM)-receptor interaction, focal adhesion pathway, Wnt signaling, and signaling by VEGF. BGN expression was positively correlated with the enrichment of the NK cells (r = 0.620, p < 0.001) and macrophages (r = 0.550, p < 0.001), but negatively correlated with the enrichment of Th17 cells (r = 0.250, p < 0.001). BGN expression was also significantly correlated with histologic grade (GI&G2 vs. G3, p < 0.001), histologic type (Diffuse type vs. Tubular type, p < 0.001), histologic stage (stage I vs. stage II and stage I vs. stage III, p < 0.001), T stage (T1 vs. T2, T1 vs. T3, and T1 vs. T4, p < 0.001) and Helicobacter pylori (HP) infection (yes vs. no, p < 0.05) in GC. High BGN expression showed significant association with poor overall survival (OS) in GC patients (HR = 1.53 (1.09-2.14), p = 0.013). The constructed nomogram can well predict the 1-, 3-, and 5-years overall survival probability of GC patients (C-index = 0.728). Conclusion: BGN plays an important role in the occurrence and progression of GC and is a potential biomarker for the diagnosis and treatment of GC.

RESUMO

There is a lack of data on drug-related problems (DRPs) among elderly patients from surgical departments. The current study is aimed at identifying and categorizing types of DRPs and assessing the severities of the DRPs. Medication orders for hospitalized patients aged ≥65 years from six surgery departments were reviewed to determine DRPs over 6 months in a tertiary teaching hospital of Chongqing, China. DRPs were classified based on the Pharmaceutical Care Network Europe classification V8.02. The severity ratings of the DRPs were assessed using the National Coordinating Council for Medication Error Reporting and Prevention classification. A total of 53,231 medication orders from 1,707 elderly patients were reviewed, and 1,061 DRPs were identified. Treatment safety (44.9%) was the most common DRP type. Drug selection (43.1%) and dose selection (43.1%) were the major causes of DRPs. A total of 75.1% of the DRPs were classified into severity categories B to D (causing no or potential harm), and 24.9% were classified as categories E to H (causing actual harm). DRPs are common in hospitalized elderly surgical patients. Pharmacists should provide medication order reviews in this vulnerable patient population.

RESUMO

It has been reported that supplementing certain amino acids has therapeutic effects on ulcerative colitis (UC). We intend to explore whether citrulline (Cit) supplementation has protective effects on UC. Fifteen male Wistar rats were divided into normal control group (NC group), UC group and UC+Cit group, with five rats in each group. The UC model was established by TNBS/ethanol method. Rats in UC+Cit group were intragastrically administered with Cit for 7 consecutive days after modeling. All rats were sacrificed after 7 days. Blood samples were collected to detect the number of monocytes. Colon tissues were taken for HE staining. Immunohistochemistry staining for CD68 and p-STAT3 were performed to detect the infiltration of monocytes and the phosphorylation of STAT3 in colon tissues. The concentrations of MCP-1, IL-6 and IL-17A and the protein expression of p-STAT3 in colon tissues were measured by ELISA and western blot methods, respectively. The body weight of UC group rats decreased significantly after 7 days (p<0.05). However, the weight loss of UC+Cit group rats was not statistically significant (p>0.05). The number of peripheral blood monocytes in UC+Cit group was significantly lower than that in UC group (p<0.05), and the infiltration of CD68-positive monocytes in the colon tissue of UC+Cit group was significantly reduced than that in UC group. The concentrations of MCP-1, IL-6 and IL-17A and the expression of p-STAT3 in colon tissues of UC+Cit group rats were significantly lower than those in UC group (both p<0.05). Our study suggests that Cit supplementation may be a potential therapy for UC.
