Background: Patients with gastric cancer (GC) are prone to lymph node metastasis (LNM), which is an important factor for recurrence and poor prognosis of GC. Nowadays, more and more studies have confirmed that exosomes can participate in tumor lymphangiogenesis. An in-depth exploration of the pathological mechanism in the process of LNM in GC may provide effective targets and improve the diagnosis and treatment effect.

Rescue RM/CS-AKI by blocking strategy with one-dose anti-myoglobin RabMAb.

Nat Commun

January 2025

School of Disaster and Emergency Medicine, Faculty of Medicine, Tianjin University, No. 92 Weijin Road, Nankai District, Tianjin, 300072, China.

Rhabdomyolysis or Crush syndrome-related AKI (RM/CS-AKI) has high mortality, and there is no effective early on-site treatment method. The critical pathogenic factor of RM/CS-AKI is the excessive free myoglobin (Mb) in blood circulation. Here, based on the concept of creating a "mobile barrier", we develop an anti-Mb rabbit monoclonal antibody (RabMAb) with high specificity, affinity, stability, and broad species reactivity.

Behav Brain Res

January 2025

Department of Anesthesiology, Tianjin Medical University General Hospital, Tianjin 300052, China; Tianjin Research Institute of Anesthesiology, Tianjin 300052, China. Electronic address:

Neuropathic pain (NP) is a chronic disease state centred on neuroinflammation with a high prevalence and limited effective treatment options. Peroxisome proliferator-activated receptor α (PPARα) has emerged as a promising target for NP management due to its anti-inflammatory properties. Recent evidence highlights the critical role of the gut microbiome and its metabolites in NP pathogenesis.

January 2025

State Key Laboratory of Experimental Hematology, National Clinical Research Center for Blood Diseases, Haihe Laboratory of Cell Ecosystem, Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College, Tianjin, 300020, China.

Background: The benefit of universal CAR-T cells over autologous CAR-T cell therapy is that they are a treatment that is ready to use. However, the prevention of graft-versus-host disease (GVHD) and host-versus-graft reaction (HVGR) remains challenging. Deleting class I of human leukocyte antigen (HLA-I) and class II of human leukocyte antigen (HLA-II) can prevent rejection by allogeneic T cells; however, natural killer (NK) cell rejection due to the loss of self-recognition remains unresolved.

First-line cadonilimab plus chemotherapy in HER2-negative advanced gastric or gastroesophageal junction adenocarcinoma: a randomized, double-blind, phase 3 trial.

Nat Med

January 2025

State Key Laboratory of Holistic Integrative Management of Gastrointestinal Cancers, Beijing Key Laboratory of Carcinogenesis and Translational Research, Peking University Cancer Hospital & Institute, Beijing, China.

Programmed cell death protein-1 (PD-1) inhibitors plus chemotherapy have been the standard of care in the first-line treatment of advanced gastric or gastroesophageal junction (G/GEJ) adenocarcinoma; however, the survival benefits are modest in patients with low programmed death ligand 1 (PD-L1) expression. Here we investigated the efficacy and safety of cadonilimab (PD-1/cytotoxic T lymphocyte antigen-4 (CTLA-4) bispecific antibody) plus chemotherapy as first-line treatment in G/GEJ adenocarcinoma.

Photobiomodulation Combined With Human Umbilical Cord Mesenchymal Stem Cells Modulates the Polarization of Microglia.

J Biophotonics

January 2025

State Key Laboratory of Advanced Medical Materials and Devices, Tianjin Key Laboratory of Neuromodulation and Neurorepair, Integrative regeneration laboratory, Institute of Biomedical Engineering, Chinese Academy of Medical Sciences & Peking Union Medical College, Tianjin, China.

Neuroinflammation plays a key role in the development of neurodegenerative diseases, with microglia regulating this process through pro-inflammatory M1 and anti-inflammatory M2 phenotypes. Studies have shown that human umbilical cord mesenchymal stem cells (hUCMSCs) modulate neuroinflammation by secreting anti-inflammatory cytokines. Photobiomodulation (PBM), a non-invasive therapy, has demonstrated significant potential in alleviating neuroinflammation.

To investigate the effect of different platelet (PLT) counts on the safety and efficacy of the double-plasma molecular absorption system (DPMAS) in patients with acute-on-chronic liver failure (ACLF). A total of 156 patients with ACLF receiving DPMAS were divided into the observed group (40 × 10/L ≤ PLT < 50 × 10/L) and the control group (PLT ≥ 50 × 10/L) according to PLT count level. The safety and efficacy indices of bleeding-related complications, PLT reduction rate, total bilirubin (TBIL) reduction rate, and 28-days survival rate after DPMAS were analyzed and compared between the two groups.

State Key Laboratory of Experimental Hematology, National Clinical Research Center for Blood Diseases, Haihe Laboratory of Cell Ecosystem, Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College, Tianjin, China.

Lactate dehydrogenase A (LDHA) is upregulated in multiple cancer types and contributes to the Warburg effect. Several studies have found that many tumor-related genes have subtypes and play important roles in promoting cancer development. Here, we identified a novel LDHA transcript, which produced a new protein 3 kDa larger than LDHA, which we named LDHAα.

Oral iron sulfide prevents acute alcohol intoxication by initiating the endogenous multienzymatic antioxidant defense system.

Sci Adv

January 2025

State Key Laboratory of Medicinal Chemical Biology, College of Pharmacy, Nankai University, Haihe Education Park, 38 Tongyan Road, Tianjin 300353, People's Republic of China.

Acute alcohol intoxication could cause multiorgan damage, including nervous, digestive, and cardiovascular systems, and in particular, irreversible damage to the brain and liver. Emerging studies have revealed that the endogenous multienzymatic antioxidant defense system (MEAODS) plays a central role in preventing oxidative stress and other toxicological compounds produced by alcohol. However, few available drugs could quickly regulate MEAODS.

Intercellular mitochondria transfer is an evolutionarily conserved process in which one cell delivers some of their mitochondria to another cell in the absence of cell division. This process has diverse functions depending on the cell types involved and physiological or disease context. Although mitochondria transfer was first shown to provide metabolic support to acceptor cells, recent studies have revealed diverse functions of mitochondria transfer, including, but not limited to, the maintenance of mitochondria quality of the donor cell and the regulation of tissue homeostasis and remodelling.
