AIM AND OBJECTIVE: Avicularin has been found to inhibit the proliferation of HepG-2 cells in vitro in the screening of our laboratory. And we intended to explain the molecular mechanism of this effect. Therefore, the combined methods of reverse molecular docking and network pharmacology were used in order to illuminate the molecular mechanisms for Avicularin against cancer. MATERIALS AND METHODS: Potential targets associated with anti-tumor effects of Avicularin were screened by reverse molecular docking, then a protein database was established through constructing the drug-protein network from literature mining data, and the protein-protein network was built through an in-depth exploration of the relationships between the proteins, and then the network topology analysis was performed...

BACKGROUND: Cereal hull color is an important quality specification characteristic. Many studies were conducted to identify genetic changes underlying cereal hull color diversity. However, these studies mainly focused on the gene level. Recent studies have suggested that metabolomics can accurately reflect the integrated and real-time cell processes that contribute to the formation of different cereal colors. METHODS: In this study, we exploited published metabolomics databases and applied several advanced computational methods, such as minimum redundancy maximum relevance (mRMR), incremental forward search (IFS), random forest (RF) to investigate cereal hull color at metabolic level...

AIM AND OBJECTIVE: A significant proportion of patients with early non-small cell lung cancer (NSCLC) can be cured by surgery. The distant metastasis of tumors is the most common cause of treatment failure. Precisely predicting the likelihood that a patient develops distant metastatic risk will help identify patients who can further intervene, such as conventional adjuvant chemotherapy or experimental drugs. MATERIALS AND METHODS: Current molecular biology techniques enable the whole genome screening of differentially expressed genes, and rapid development of a large number of bioinformatics methods to improve prognosis...

BACKGROUND: Circulating endothelial progenitor cells (EPCs) have regenerative capacities and play an important role in vessel wall homeostasis. When attracted to the site of vessel wall injury, EPCs rapidly differentiate into a functional layer as part of the healing process. The Genous TM endothelial progenitor cell (EPC) capturing stent is coated with anti-human CD34+ antibodies which combine with circulating EPCs from the peripheral blood to the stent surface. OBJECTIVE: This meta-analysis aims to explore the Genous TM endothelial progenitor cell capturing stent in coronary artery disease (CAD) adverse event rate after one year follow-up...

BACKGROUND: Patients with previously treated non-small-cell lung cancer (NSCLC) have limited treatment options. A novel treatment based on programed death 1 (PD-1)/programed death ligand 1 (PD-L1) inhibitors has emerged as promising therapeutic options for advanced NSCLC. We assessed oncological outcomes of PD-L1 antibody versus docetaxel in previously treated NSCLC.

The association between vitamin D receptor (VDR) genetic polymorphism and lung cancer risk has been evaluated by previous meta-analyses. Due to emergence of novel studies and inappropriate inclusion of overlapping populations, an update meta-analysis on recent evidences is necessarily needed. We comprehensively searched databases of PubMed, Web of Science and Chinese National Knowledge Infrastructure and finally obtained 7 eligible studies according to the inclusion criteria. Four positions on VDR gene, namely ApaI (rs7975232), BsmI (rs1544410), FokI (rs10735810) and TaqI (rs731236), were considered in this investigation...

BACKGROUND: Pre-treated patients with first-line treatment can be offered a second treatment with the aim of improving their poor clinicalprognosis. The therapy of metastatic colorectal cancer (CRC) patients who did not respond to first-line therapy has limited treatment options. Recently, many studies have paid much attention on the efficacy of bevacizumab as adjuvant treatment for metastatic colorectal cancer. OBJECTIVES: We aim to evaluate the efficacy and toxicity of bevacizumab plus chemotherapy compared with bevacizumab-naive based chemotherapy as second-line treatment in people with metastatic CRC...

BACKGROUND: Esophageal cancer (EC) is a common digestive system tumor, characterized by high invasion, apparent lethality, and poor prognosis. Direct diffusion is the major metastatic mechanism of early EC, whereas advanced EC is spread mainly by lymphatic metastasis, but also can be transferred to the liver, lungs, bones, and so on, by hematogenous metastasis. The incidence of bone metastasis in esophageal cancer is low, and maxillary metastasis of EC is more rare. OBJECTIVE: To explore the differential diagnosis in ECMM, the rare metastasis of EC, and the possible mechanisms and predictors of bone metastasis...

BACKGROUND: Hemolymphangioma is a rare benign tumor. To the best of our knowledge, there were only 10 reports of this tumor of the pancreas until March 2018. CASE REPORT: Here, we reported a large invasive hemolymphangioma of the pancreas in a young woman with a complaint of abdominal distension and an epigastric mass about 3 weeks. She was found to have a huge multilocular cystic tumor at the neck and body of pancreas on computed tomography. She was eventually diagnosed with hemolymphangioma of the pancreas after operation...

AIM AND OBJECTIVE: Leukemia is the second common blood cancer after lymphoma, and its incidence rate has an increasing trend in recent years. Leukemia can be classified into four types: acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL), and chronic myelogenous leukemia (CML). More than forty drugs are applicable for different types of leukemia based on the discrepant pathogenesis. Therefore, the identification of specific drug-targeted biological processes and pathways is helpful to determinate the underlying pathogenesis among such four types of leukemia...

BACKGROUND: As a newly uncovered post-translational modification on the ε-amino group of lysine residue, protein malonylation was found to be involved in metabolic pathways and certain diseases. Aside from experimental approaches, several computational methods based on machine learning algorithms were recently proposed to predict malonylation sites. However, previous methods failed to address imbalanced data sizes between positive and negative samples. OBJECTIVE: In this study, we identified the significant features of malonylation sites in a novel computational method which applied machine learning algorithms and balanced data sizes by applying synthetic minority over-sampling technique...

AIM AND OBJECTIVE: There are several diseases having a complicated mechanism. For such complicated diseases, a single drug cannot treat them very well because these diseases always involve several targets and single targeted drugs cannot modulate these targets simultaneously. Drug combination is an effective way to treat such diseases. However, determination of effective drug combinations is time- and cost-consuming via traditional methods. It is urgent to build quick and cheap methods in this regard...

Background Transverse colostomy is commonly performed to create temporary stoma in rectal cancer patients after neoadjuvant chemoradiotherapy. Conventional methods are either difficulty to implement or to care for. To resolve these problems, we herein describe a modified transverse colostomy method. MATERIAL AND METHODS: Two sutures of peritoneum were made as "bridges" to support the stoma. Absorbable sutures were utilized to reinforce the stoma. Once the stoma was created, the stoma bag was immediately placed on the skin...

BACKGROUND: Lymphadenectomy has been widely used in the treatment of malignant germ cell tumor of the ovary (OGCT), which is a kind of ovarian cancers occurred mostly in young women and adolescent girls. But the clinical decision mainly depends on the doctor's experience without a well-defined guideline. This population-based study was to evaluate the prognostic impact of lymphadenectomy in different stages of malignant germ cell tumors of the ovary. METHODS: Patients with known status of lymphadenectomy in different stages of OGCT were explored from the Surveillance, Epidemiology, and End Results (SEER) program database from 1973 to 2013...
