[Objective] To explore the clinical significance and application value of establishing a database for red blood cell alloantibody detection. [Methods] Patients who were scheduled for blood transfusion in our hospital from January 1, 2020 to May 1, 2024 were selected as the research subjects. A red blood cell alloantibody detection database was established using Microsoft Office Excel software to register the detection data of patients' alloantibodies and antibodies of undetermined specificity (AUS). A retrospective analysis was conducted on the clinical characteristics, antibody distribution, antibody decay and repeat positivity of the patients in the database. The LISS-IAT method was routinely used for antibody screening and identification. [Results] Among the alloantibodies, the Rh blood group system had the highest detection rate, followed by antibodies of the MNS blood group system and the Lewis blood group system. The predominant antibody in the Rh blood group system was anti-E. In the univariate analysis, the positivity of antibody was significantly associated with the patient's gender, age, blood transfusion history, pregnancy history and type of disease (all P<0.001). In the database, 48 patients experienced antibody decay, accounting for 15.24%(48/315), with an average time span of antibody decay ranging from 22 to 1 324 days. Six cases showed repeat positivity after decay, which were related to blood transfusions. The shortest interval between blood transfusions that led to antibody repeat positivity was 3 days, and the longest interval was 427 days. Among 58 cases with AUS, 3 converted into alloantibodies, among which 2 were anti-E and 1 was anti-Lea. [Conclusion] Establishing a red blood cell alloantibody detection database is an effective way to guide ambiguous cross-matching in clinical practice and is also an effective measure for the management of transfusion risks.

Objective:
Neuronal apoptosis is considered to be a critical process in spinal cord injury (SCI). Despite growing evidence of the antiapoptotic, anti-inflammatory, and modulation of ischemic injury tolerance effects of extracellular ubiquitin (eUb), existing studies have paid less attention to the impact of eUb in neurological injury disorders, particularly in SCI. This study aimed to investigate whether eUb can play a protective role in neurons, both in vitro and in vivo, and explores the underlying mechanisms.
Methods:
By utilizing an oxygen glucose deprivation cellular model and a SCI rat model, we firstly investigated the therapeutic effects of eUb on SCI and further explored its effects on neuronal autophagy and mitochondria-dependent apoptosis-related indicators, as well as the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mechanical target of rapamycin (mTOR) signaling pathway.
Results:
In the SCI models both in vivo and in vitro, early intervention with eUb enhanced neuronal autophagy and inhibited mitochondrial apoptotic pathways, significantly mitigating SCI. Further studies had shown that this protective effect of eUb was mediated through its receptor, CXC chemokine receptor type 4 (CXCR4). Additionally, eUb-enhanced autophagy and antiapoptotic effects were possibly associated with inhibiting the PI3K/Akt/mTOR pathway.
Conclusion
In summary, the study demonstrates that early eUb intervention can enhance autophagy and inhibit mitochondrial apoptotic pathways via CXCR4, protecting neurons and promoting SCI repair.

Lung cancer is the malignant tumor with the highest incidence and mortality rates globally. Current treatment methods for lung cancer primarily include surgery, chemotherapy, targeted therapy, and immunotherapy. However, the main limitations of these treatments are their side effects, the drug resistance, and the economic burden they impose. As a critical cancer pathway, the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling pathway regulates tumor occurrence and development through multiple mechanisms by influencing various downstream targets. Consequently, the JAK/STAT signaling pathway offers a promising avenue for lung cancer treatment research. Numerous studies have demonstrated that the JAK/STAT signaling pathway plays a key role in the proliferation and growth of lung cancer cells, angiogenesis, epithelial-mesenchymal transition (EMT), metabolic alterations, remodeling of the immune microenvironment, and the development of treatment resistance. Traditional Chinese medicine (TCM) has garnered increasing attention due to its minimal side effects, low economic burden, and its potential to enhance efficacy and reduce toxicity when used in conjunction with Western medicine. In addition to traditional Chinese medicine compounds, a growing number of Chinese medicine monomers have come into the spotlight because of their more targeted effects. Numerous studies investigating the regulation of the JAK/STAT signaling pathway by TCM in the treatment of lung cancer have demonstrated that TCM can inhibit the proliferation and invasion of lung cancer cells, tumor angiogenesis, and EMT, improve the inflammatory and immunosuppressive microenvironments, and enhance treatment sensitivity by intervening in the JAK/STAT signaling pathway, thereby impeding the progression of lung cancer. In recent years, the research on the regulation of this pathway by TCM in the treatment of lung cancer has been updated rapidly. However, the summary of these studies has not been updated in time. This review summarizes and reflects on the recent research findings regarding the regulation of the JAK/STAT signaling pathway by TCM to intervene in lung cancer from three aspects, introducing the JAK/STAT pathway, elaborating the mechanism of this pathway in lung cancer, and exploring the intervention of TCM in the treatment of lung cancer through this pathway, to provide more reference for the treatment of lung cancer in the future.

Multidrug resistant organism refers to bacteria that are insensitive to three or more antibiotics commonly used in clinic, including Pseudomonas aeruginosa, Acinetobacter Baumannii and Klebsiella pneumoniae, etc. MDRO infection is a major factor affecting the survival rate after lung transplantation (LTx), accounting for 30% of the causes of death in the first year after transplantation. Antibiotic treatment has low specificity and is prone to drug resistance. The development of new drugs has a long cycle and high cost, with significant limitations. Phage has high specificity for bacteria, which can proliferate in large quantities in the infected lesion and co-evolve with bacteria during the action process. Phage also have a good killing effect on MDRO, which is expected to make up for the deficiencies of existing antibiotic therapy. This article reviews the development background and mechanism of action of phage therapy, and summarizes its application status and early clinical trial results in the field of LTx, in order to providing new thinking paths for clinical work.

OBJECTIVE To establish the HPLC fingerprint of Xintong granules and the quantitative analysis of multi- components by single-marker method (QAMS) to determine the contents of 7 components, so as to provide a scientific basis for their quality control. METHODS HPLC method was used to establish the fingerprints for 10 batches of Xintong granules (No. S1- S10), and similarity evaluation, cluster analysis (CA) and partial least squares-discriminant analysis (PLS-DA) were performed. At the same time, the contents of seven components, including puerarin, daidzin, calycosin-7-O- β -D-glucoside, stilbene glycoside, naringin, icariin and tanshinone ⅡA, were determined by QAMS method, and were compared with the results of external standard method. RESULTS A total of 18 common peaks were marked and 7 peaks were identified in the HPLC fingerprints for 10 batches of Xintong granules, namely puerarin (peak 4), daidzin (peak 7), calycosin-7-O-β-D-glucoside (peak 9), stilbene glycoside (peak 10), naringin (peak 12), icariin (peak 17), and tanshinone ⅡA (peak 18); the similarities among them were more than 0.990, and CA and PLS-DA results showed that S4-S5,S8-S10,S1-S3 and S6-S7 were clustered into three categories, respectively. Using naringin as the internal standard, the contents of puerarin, daidzin, calycosin-7-O-β-D-glucoside, stilbene glycoside, icariin and tanshinone ⅡA were determined to be 7.868 1-10.181 2, 1.709 2-2.374 1, 0.285 2-0.326 3, 1.024 1- 1.523 9, 0.140 2-0.290 4, and 0.077 1-0.219 4 mg/g, respectively, by the QAMS. These results showed no significant differences compared to those obtained by the external standard method. CONCLUSIONS Established HPLC fingerprint and QAMS method are convenient, stable and accurate, which can provide a basis for the quality evaluation of Xintong granules.
