L-Carnitine and Acetyl-L-Carnitine: Potential Novel Biomarkers for Major Depressive Disorder.

The lack of biomarkers greatly limits the diagnosis and treatment of major depressive disorder (MDD). Endogenous L-carnitine (LC) and its derivative acetyl-L-carnitine (ALC) play antidepressant roles by improving brain energy metabolism, regulating neurotransmitters and neural plasticity. The levels of ALC in people and rodents with depression are significantly reduced.

Infection is associated with elevated serum concentrations of antipsychotic drugs.

We aimed to investigate the effects of infection on serum concentrations of different antipsychotics in inpatients with respiratory tract infections treated with psychiatric drugs, including risperidone, clozapine, quetiapine, and aripiprazole. All patients underwent therapeutic drug monitoring (TDM) and routine blood tests during infection and noninfection periods. The Wilcoxon signed-rank test was used to analyze intra-individual differences in dose-corrected serum concentrations (C/D) levels in infection and noninfection periods.

PD-1/PD-L1 enhanced cisplatin resistance in gastric cancer through PI3K/AKT mediated P-gp expression.

Background: Programmed cell death receptor 1 (PD-1) is an immunosuppressive molecule expressed on T cells, and its ligand (PD-L1) which expressed on tumor cells play pivotal roles in regulating host immune responses. However, little is known whether PD-1/PD-L1 axis could directly activates intracellular oncogenic signaling pathways in tumor cells, leading to tumor resistance.

Methods: In the present study, the expression of PD-1 and PD-L1 in the tissues of gastric cancer was detected by western blot and immunofluorescence.

Aidi Injection, a Traditional Chinese Medicine Injection, Could Be Used as an Adjuvant Drug to Improve Quality of Life of Cancer Patients Receiving Chemotherapy: A Propensity Score Matching Analysis.

Background: Clinical research has paid increasing attention to quality of life (QoL) in recent years, but the assessment of QoL is difficult, hampered by the subjectivity, complexity, and adherence of patients and physicians. According to previous studies, QoL in cancer patients is related to performance status (PS) and influenced by chemotherapy-related toxicity. Aidi injection, a traditional Chinese medicine injection, is used as an adjuvant drug to enhance effectiveness of chemotherapy.
