FABP3 Induces Mitochondrial Autophagy to Promote Neuronal Cell Apoptosis in Brain Ischemia-Reperfusion Injury.

This study elucidates the molecular mechanisms by which FABP3 regulates neuronal apoptosis via mitochondrial autophagy in the context of cerebral ischemia-reperfusion (I/R). Employing a transient mouse model of middle cerebral artery occlusion (MCAO) established using the filament method, brain tissue samples were procured from I/R mice. High-throughput transcriptome sequencing on the Illumina CN500 platform was performed to identify differentially expressed mRNAs.

[Establishment of Cytarabine-resistant Acute Lymphoblastic Leukemia Cell Lines and Its Resistance Mechanism].

Objective: To establish cytarabine-resistant acute lymphoblastic leukemia (ALL) cell lines and investigate its possible resistant mechanism.

Methods: Low-concentration cytarabine (Ara-C) continuously induced and cultured Jurkat and Nalm-6 cells to construct cytarabine-resistant cell lines Jurkat/Ara-C and Nalm-6/Ara-C. The cell viability was detected by CCK-8 assay, and the distribution of cell cycle was detected by flow cytometry.

Salidroside overcomes dexamethasone resistance in T-acute lymphoblastic leukemia cells.

The aim of the present study was to analyze whether the use of salidroside (SAL) could overcome dexamethasone (DEX) resistance in T-acute lymphocytic leukemia cells. The human T-ALL DEX-resistant cell line, CEM-C1 and the DEX-sensitive cell line, CEM-C7 were used in the current study. The proliferation inhibition rates in these cells, treated with SAL and DEX alone, and in combination were detected using a Cell Counting Kit-8 assay, while the morphological changes of the cells were observed using an inverted microscope.

Autophagy inhibitors increase the susceptibility of KRAS-mutant human colorectal cancer cells to a combined treatment of 2-deoxy-D-glucose and lovastatin.

RAS-driven colorectal cancer relies on glucose metabolism to support uncontrolled growth. However, monotherapy with glycolysis inhibitors like 2-deoxy-D-glucose causes limited effectiveness. Recent studies suggest that anti-tumor effects of glycolysis inhibition could be improved by combination treatment with inhibitors of oxidative phosphorylation.

Progress in research on childhood T-cell acute lymphocytic leukemia, Notch1 signaling pathway, and its inhibitors: A review.

Childhood leukemia is cancer that seriously threatens the life of children in China. Poor sensitivity to chemotherapy and susceptibility to drug resistance are the reasons for the treatment of T-cell acute lymphocytic leukemia (T-ALL) being extremely difficult. Moreover, traditional intensive chemotherapy regimens cause great damage to children.

[Relationship between interleukin-17A gene polymorphisms and the susceptibility to childhood asthma].

Objective: To explore the relationship between polymorphisms of interleukin-17A (IL-17A) gene promoter (-197G/A and -692C/T) and the susceptibility to childhood asthma, to further identify the candidate genes for asthma, and to provide a basis for early prevention of asthma in high-risk children.

Methods: Sixty-five outpatients or inpatients with childhood asthma between August 2013 and August 2015 were assigned to asthma group. Seventy healthy children within the same period were assigned to control group.

[Comparison of three types of self-treatments for posterior canal benign paroxysmal positional vertigo: modified Epley maneuver, modified Semont maneuver and Brandt-Daroff maneuver].

Objective: To compare the efficacy and recurrence rates of modified Epley maneuver, modified Semont maneuver and Brandt-Daroff maneuver in patients with posterior canal benign paroxysmal positional vertigo (PC-BPPV).

Methods: One hundred and sixty-eight patients with unilateral PC-BPPV were included in the study, which were divided into four groups randomly, 45 with modified Epley maneuver (group 1), 43 with modified Semont maneuver (group 2), and 40 with Brandt-Daroff maneuver (group 3). There were 40 controls without physical therapy technique (group 4) included.

Prenylated xanthones from the bark of Garcinia xanthochymus and their 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities.

Garcinia xanthochymus has been widely used in traditional Chinese medicine for expelling worms and removing food toxins. Bioassay-guided fractionation of an EtOAc-soluble extract of G. xanthochymus stem bark led to the isolation of six new xanthones.

Three new xanthones from Garcinia xanthochymus.

To study xanthones from the barks of Garcinia xanthochymus, the constituents were isolated by normal-phase and reverse-phase silica gel column chromatography from the EtOAc extract. Their structures were elucidated by spectral analysis. Three new xanthones were purified and identified as 1,2,5-trihydroxy-6-methoxyxanthone (1), 1,4,6-trihydroxy-5-methoxyxanthone (2), 1,2,7-trihydroxy-4-(1,1-dimethylallyl) xanthone (3).
