RESUMO
Metal-organic frameworks (MOFs) are mixed porous materials which are composed of metal clusters or ions and organic pillars. Given their channel tunability, high porosity, large specific surface area, and good biocompatibility, MOFs can be combined with various biological macromolecules. In recent years, they have been widely studied in the field of biomedicine, especially in the loading of anti-tumor drugs, showing great application prospects. Multifunctional anti-tumor MOF combined with different therapeutic methods provides a new idea and method for tumor treatment. On the basis of the structure of MOF, this paper introduces the advantages of using MOF to load anti-tumor drugs and reviews the application of MOF in tumor therapy.
RESUMO
PLEK2 (Pleckstrin-2) is a subtype of platelets and leukocytes Pleckstrin, located at 14q23.3-q24.1. Its encoded protein contains 353 amino acids. It plays a role in a variety of cells other than immune cells. The research is relatively limited, mainly involved in the reorganization of cytoskeleton proteins and the regulation of cell extension and migration. PLEK2 plays an important role in the occurrence, development and metastasis of a variety of tumors, and can participate in the regulation of a variety of signal pathways, thereby regulating tumor cell proliferation, invasion and metastasis. PLEK2 is up-regulated in a variety of tumors and has carcinogenic properties. This article reviews the regulatory role of PLEK2 in tumorigenesis, development and metastasis and its impact on tumor prognosis.
RESUMO
Malignant tumor has become one of the main reasons threatening human health. Invasion and metastasis are the important biological characteristics of malignant tumor and the main cause of death of malignant tumor patients. CPNE is highly expressed in malignant tumors, and its family may interact with proteins and MicroRNA to participate in MAPK, PI3K/AKT and other signal pathways to mediate tumor cell proliferation, invasion and metastasis. This article reviews the expression of CPNE in malignant tumors and its effect on invasion and metastasis.
RESUMO
Objective:To systematically evaluate the clinical effect and safety of bevacizumab combined with FOLFOX regimen in patients with advanced colorectal cancer.Methods:An electronic search of Pubmed, Embase, CNKI and other Chinese and English databases were retried from their inception to December 2018 to identify relevant literatures, by taking "Bevacizumab, FOLFOX, Advanced Colorectal Cancer, Randomized Controlled Trial" as the keywords for retrieval. Patients were divided into a combination group (bevacizumab combined with FOLFOX program) and a control group (using FOLFOX program alone) according to the treatment method, using Revman 5.3 software for meta-analysis.Results:A total of 11 articles, involving 3178 patients, were included with 1599 in the combination group and 1579 in the control group. The objective group response rate ( OR=3.15, 95% CI: 2.25 ~ 4.40, Z=6.71, P<0.000 01) and disease control rate ( OR=2.73, 95% CI: 1.91 ~ 3.90, Z=5.49, P<0.000 1) in combination group were higher than those in the control group. In terms of adverse reactions, the incidence of gastrointestinal reactions in the combination group was higher than that in the control group ( OR=1.29, 95% CI: 1.07~1.55, Z=2.64, P=0.008 ), There was no significant difference in the incidence of liver injury, leukopenia, hypertension, and neurotoxicity between the two groups. Conclusion:Bevacizumab combined with FOLFOX regimen is more effective than FOLFOX regimen for patients with advanced colorectal cancer, but it will increase the risk of gastrointestinal reactions.
RESUMO
Colorectal cancer is one of the most common malignant tumors,early diagnosis and treatment are the important factors affecting colorectal cancer's prognosis.It has been proved that colorectal cancer's diagnosis combined with biomolecular markers is non-invasive,economical and specific at the same time,biomarkers are valuable in predicting and monitoring the chemoresistance of colorectal cancer.This article mainly reviews the prediction of liver metastasis of colorectal cancer,drug resistance of postoperative chemotherapy in colorectal cancer and the monitoring of drug resistance in the course of chemotherapy by CD44v6.

Objective To study the changes of insulin-like growth factor-1(IGF-1) in serum of patients with obstructive jaundice.Methods The clinical data of 20 patients with obstructive jaundice were collected and the measurement of serum TNF-?,ALT, ALP, endotoxin and IGF-1 were performed. Results The serum IGF-1 in obstructive jaundice was significantly lower than that in gallbladder stone(P
