Bibliometric analysis of aptamer-conjugated nanoparticles for diagnosis in the last two decades.

Aptamer-conjugated nanoparticles for diagnosis have recently gained increasing attention. Here, we performed a bibliometric analysis to provide an overview of this field over the past two decades..

[Reversal of Drug Resistance in K562/ADM Cells Caused by RA and the Related Mechanisms].

Objective: To investigate the effect of ursane triterpenoids 3β,19α-dihydroxyursu-12-ene-23,28-dicarboxylic acid (Rotundioic acid, RA) on the sensitivity of adriamycin-resistant K562 cells (K562/ADM Cell) anti-tumor drug, and to explore the effect and mechanism of RA on the multidrug resistance of K562/ADM cells.

Methods: CCK-8 method was used to detect the effect of RA on the sensitivity of K562 cells and K562/ADM cells to anti-tumor drug. Reverse transcription-polymerase chain reaction (RT-PCR) and Western blot were used to detect the expression level of mRNA and the protein in K562 and K562/ADM cells, and the effect of RA on the expression of MDR1 mRNA and P-gp in K562/ADM cells was also detected; Western blot was used to detect the expression of p-JNK, p-p38 and p-ERK1/2 in K562/ADM cells.

[Research Progress on Application of CRISPR/Cas Genome Editing Technology in Hematological Diseases -Review].

CRISPR/Cas genome editing technology is a newly developed powerful tool for genetic manipulation, which can be used to manipulate the genome at specific locations precisely, to restore the function of genetic defect cells, and to develop various disease models. In recentl years, with the advances of precise genome manipulation, CRISPR/Cas technology has been applied to many aspects of diseases research and becomes an unique tool to investigate gene function and discover new therapeutic targets for genetic diseases. Nowadays, CRISPR/Cas technology has been a hot research point in agriculture, graziery, biotechnology and medicine.

[Expression and Significance of NLRP3, ASC and AIM2 in Patients with Acute Leukemia].

Objective: To explore the expression and significance of NLR family, pyrin domain containing 3 (NLRP3), apoptosis associated speck like protein containing a CRAD (ASC) and absent in melanoma 2 (AIM2) of patients with acute leukemia.

Methods: The petipheral blood samples of 19 patients with ALL and 41 patients with ANLL as the AL group (each 20 cases of newly diagnosed, relapsed and complete remission group) and 20 cases of non-hematologic malignancies as the control group were collected from July 2013 to July 2014 in the First Affiliated Hospital of Gannan Medical University. The expression levels of NLRP3, ASC and AIM2 in peripheral blood plasma were determined by ELISA.

[Research Progress on Long Non-Coding RNA in Hematological Malignancies--Review].

Long non-coding RNA (LncRNA) is defined as a class of transcripts more than 200 nucleotides in length and without the protein-coding function. It has been found for years, however, that little is known about the potential role of LncRNA in humans. But recent studies showed that LncRNA can regulate the coding-gene expression and participate in effects of human body.

[Expression of HMGB1 and NF-κB in Patients with Acute Leukemia and Its Significance].

Objective: To explore the expression of high mobility group box protein 1 (HMGB1) and nuclear factor-kappa B (NF-κB) in patients with acute leukemia and its significance.

Method: 20 samples of bone marrow and peripheral blood from each acute leukemia groups (newly diagnozed, relapsed and complete remission groups) and 20 samples as control from patients with no-hematologic malignancies were collected. The expression level of HMGB1 in peripheral blood plasma was determined by ELISA; HMGB1 and NF-κB level in mononuclear cells were examined by RT-PCR.
