Objective: To observe the effect of electroacupuncture (EA) combined with Zhuang-medicine-thread moxibustion on silent information regulator-1 (SIRT1)/nuclear factor kappa B (NF-κB) signal pathway and inflammatory factor expression in gastric antrum tissue of diabetic gastroparesis (DGP) rats, so as to explore its mechanism underlying improvement of DGP.
Methods: Male SD rats were randomly divided into normal, model, medication, EA, Zhuang-medicine-thread moxibustion (moxibustion) and EA+moxibustion groups (=12 per group). The DGP model was established by intraperitoneal injection of streptozotocin (STZ).
Interleukin6 (IL-6) is a key driver of hyperinflammation in COVID-19, and its level strongly correlates with disease progression. To investigate whether variability in COVID-19 severity partially results from differential expression, functional single-nucleotide polymorphisms (SNPs) of were determined in Chinese COVID-19 patients with mild or severe illness. An Asian-common haplotype defined by promoter SNP rs1800796 and intronic SNPs rs1524107 and rs2066992 correlated with COVID-19 severity.

As a serine/threonine kinase, ATM has an array of downstream phosphorylation substrates, including checkpoint effector checkpoint kinase 2 (CHK2). ATM inhibits cell cycle progression by phosphorylating and activating CHK2, which plays an important role in the formation and development of tumors and participates in DNA repair responses after double-stranded DNA breaks.

In the present study, we explored the roles and underlying mechanism of the lncRNA Nuclear enriched abundant transcript 1 (NEAT1) in ARDS. The expression levels of genes, proteins and pro-inflammatory cytokines in patients with ARDS, LPS-stimulated cells and septic mouse models were quantified using qPCR, western blotting and ELISA assays, respectively.

The potential of allogeneic mesenchymal stem cells in treating systemic lupus erythematosus (SLE) was investigated in this study. MRL/lpr mice which can develop acquired SLE-like phenotypes were selected as an animal model.

Methods: Eight healthy 12-month-old female Guizhou mini-pigs were used for the present experiment. In the first operation, empty double-cavity bone harvest chambers (n = 8) were implanted into the femoral metaphysis of the animals as a blank control group.

Objective: To investigate whether plasma from patients with systemic lupus erythematosus (SLE) inhibits the suppressive effects of mesenchymal stem cells (MSCs) on lupus B lymphocytes.
Methods: MSCs isolated and expanded from the bone marrow of healthy donors were co-cultured with B cells purified from the peripheral blood of SLE patients in the presence of fetal bovine serum or pooled plasma from SLE patients, and the proliferation and maturation of the B lymphocytes were analyzed.
Results: s Co-culture with normal MSCs obviously inhibited the proliferation of lupus B cells and suppressed the maturation of B lymphocytes, which showed lowered expressions of CD27 and CD38.
Objective: To study the regulatory effects of miR-21 on breast cancer cell line proliferation and invasion as well as the downstream target genes.
Methods: Breast cancer cell lines MCF-7 were cultured and transfected with miR-21 mimics and the corresponding negative control mimics (NC mimics), and then MTS kits were used to detect cell viability. Transwell experiment was used to detect cell invasion ability, and fluorescence quantitative PCR was used to detect the expression of proliferation and invasion-related genes in cells.
