OBJECTIVE: To examine the therapeutic effect of Fangji Fuling Decoction (FFD) on sepsis through network pharmacological analysis combined with in vitro and in vivo experiments. METHODS: A sepsis mouse model was constructed through intraperitoneal injection of 20 mg/kg lipopolysaccharide (LPS). RAW264.7 cells were stimulated by 250 ng/mL LPS to establish an in vitro cell model. Network pharmacology analysis identified the key molecular pathway associated with FFD in sepsis. Through ectopic expression and depletion experiments, the effect of FFD on multiple organ damage in septic mice, as well as on cell proliferation and apoptosis in relation to the mitogen-activated protein kinase 14/Forkhead Box O 3A (MAPK14/FOXO3A) signaling pathway, was analyzed. RESULTS: FFD reduced organ damage and inflammation in LPS-induced septic mice and suppressed LPS-induced macrophage apoptosis and inflammation in vitro (P<0.05). Network pharmacology analysis showed that FFD could regulate the MAPK14/FOXO signaling pathway during sepsis. As confirmed by in vitro cell experiments, FFD inhibited the MAPK14 signaling pathway or FOXO3A expression to relieve LPS-induced macrophage apoptosis and inflammation (P<0.05). Furthermore, FFD inhibited the MAPK14/FOXO3A signaling pathway to inhibit LPS-induced macrophage apoptosis in the lung tissue of septic mice (P<0.05). CONCLUSION FFD could ameliorate the LPS-induced inflammatory response in septic mice by inhibiting the MAPK14/FOXO3A signaling pathway.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Ulcerative colitis(UC) is a recurrent, intractable inflammatory bowel disease. Coptidis Rhizoma and Bovis Calculus, serving as heat-clearing and toxin-removing drugs, have long been used in the treatment of UC. Berberine(BBR) and ursodeoxycholic acid(UDCA), the main active components of Coptidis Rhizoma and Bovis Calculus, respectively, were employed to obtain UDCA-BBR supramolecular nanoparticles by stimulated co-decocting process for enhancing the therapeutic effect on UC. As revealed by the characterization of supramolecular nanoparticles by field emission scanning electron microscopy(FE-SEM) and dynamic light scattering(DLS), the supramolecular nanoparticles were tetrahedral nanoparticles with an average particle size of 180 nm. The molecular structure was described by ultraviolet spectroscopy, fluorescence spectroscopy, infrared spectroscopy, high-resolution mass spectrometry, and hydrogen-nuclear magnetic resonance(H-NMR) spectroscopy. The results showed that the formation of the supramolecular nano-particle was attributed to the mutual electrostatic attraction and hydrophobic interaction between BBR and UDCA. Additionally, supramolecular nanoparticles were also characterized by sustained release and pH sensitivity. The acute UC model was induced by dextran sulfate sodium(DSS) in mice. It was found that supramolecular nanoparticles could effectively improve body mass reduction and colon shortening in mice with UC(P<0.001) and decrease disease activity index(DAI)(P<0.01). There were statistically significant differences between the supramolecular nanoparticles group and the mechanical mixture group(P<0.001, P<0.05). Enzyme-linked immunosorbent assay(ELISA) was used to detect the serum levels of tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6), and the results showed that supramolecular nanoparticles could reduce serum TNF-α and IL-6 levels(P<0.001) and exhibited an obvious difference with the mechanical mixture group(P<0.01, P<0.05). Flow cytometry indicated that supramolecular nanoparticles could reduce the recruitment of neutrophils in the lamina propria of the colon(P<0.05), which was significantly different from the mechanical mixture group(P<0.05). These findings suggested that as compared with the mechanical mixture, the supramolecular nanoparticles could effectively improve the symptoms of acute UC in mice. The study provides a new research idea for the poor absorption of small molecules and the unsatisfactory therapeutic effect of traditional Chinese medicine and lays a foundation for the research on the nano-drug delivery system of traditional Chinese medicine.

Background In mainland China, patients with neovascular age-related macular degeneration (nAMD) have approximately an 40% prevalence of polypoidal choroidal vasculopathy (PCV). This disease leads to recurrent retinal pigment epithelium detachment (PED), extensive subretinal or vitreous hemorrhages, and severe vision loss. China has introduced various treatment modalities in the past years and gained comprehensive experience in treating PCV.Methods A total of 14 retinal specialists nationwide with expertise in PCV were empaneled to prioritize six questions and address their corresponding outcomes, regarding opinions on inactive PCV, choices of anti-vascular endothelial growth factor (anti-VEGF) monotherapy, photodynamic therapy (PDT) monotherapy or combined therapy, patients with persistent subretinal fluid (SRF) or intraretinal fluid (IRF) after loading dose anti-VEGF, and patients with massive subretinal hemorrhage. An evidence synthesis team conducted systematic reviews, which informed the recommendations that address these questions. This guideline used the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach to assess the certainty of evidence and grade the strengths of recommendations. Results The panel proposed the following six conditional recommendations regarding treatment choices. (1) For patients with inactive PCV, we suggest observation over treatment. (2) For treatment-na?ve PCV patients, we suggest either anti-VEGF monotherapy or combined anti-VEGF and PDT rather than PDT monotherapy. (3) For patients with PCV who plan to initiate combined anti-VEGF and PDT treatment, we suggest later/rescue PDT over initiate PDT. (4) For PCV patients who plan to initiate anti-VEGF monotherapy, we suggest the treat and extend (T&E) regimen rather than the pro re nata (PRN) regimen following three monthly loading doses. (5) For patients with persistent SRF or IRF on optical coherence tomography (OCT) after three monthly anti-VEGF treatments, we suggest proceeding with anti-VEGF treatment rather than observation. (6) For PCV patients with massive subretinal hemorrhage (equal to or more than four optic disc areas) involving the central macula, we suggest surgery (vitrectomy in combination with tissue-plasminogen activator (tPA) intraocular injection and gas tamponade) rather than anti-VEGF monotherapy. Conclusions Six evidence-based recommendations support optimal care for PCV patients' management.

Astragali Radix, a medicinal herb for invigorating Qi, has anti-aging, anti-tumor, immunoregulatory, blood sugar-and lipid-lowering, anti-fibrosis, anti-radiation and other pharmacological effects. This article reviewed the studies about the chemical components and pharmacological effects of Astragali Radix. According to the theory of quality markers(Q-markers) of Chinese medicinal materials, we predicted the Q-markers of Astragali Radix from traditional efficacy, chemical component validity, measurability, plant phylogeny, and pharmacokinetis. The results showed that total polysaccharides, flavonoids(e.g., calycosin-7-O-β-D-glucoside, formononetin, calycosin, quercetin, and ononin), and saponins(e.g., astragalosides Ⅱ, Ⅲ, and Ⅳ) can be taken as the main Q-markers. This review lays a foundation for regulating the quality research and standard establishment of Astragali Radix, and benefits the control and quality supervision of the production process of Astragali Radix and its related products.

Although anti-thrombotic therapy has been successful for prevention of deaths from acute myocardial infarction (MI), by far, there are few preventive and therapeutic options for ischemic heart failure (IHF) after MI. Qi-Tai-Suan (QTS) is an oleanolic acid (OA) derivative which once underwent a clinical trial for treating hepatitis. In this study, we investigated the potential cardioprotective effect of QTS on IHF. IHF mouse model was constructed by coronary artery ligation in male C57BL/6J mice, and the protective effects of QTS on IHF were examined by echocardiography measurement, histological and TUNEL analysis, etc. We found that QTS exhibited promising cardioprotective effect on IHF. QTS treatment significantly improved cardiac function of IHF mice and the symptoms of heart failure. Notably, QTS had much better oral bioavailability (F = 41.91%) in mice than its parent drug OA, and took effects mainly as its original form. Mechanistically, QTS ameliorated ischemic heart failure likely through suppression of cardiac apoptosis, inflammation and fibrosis. Taken together, QTS holds great promise as a preventive and therapeutic agent for ischemic heart failure and related diseases.

ObjectiveTo explore the therapeutic effect and possible mechanism of Banxia Xiexintang and its disassembled prescriptions in regulating the flora disorder induced by mixed antibiotics in young rats. MethodSeventy male BALB/C young rats were randomly assigned into 7 groups： blank group， model group， Bifidobacterium tetralogy viable tablets （0.68 g·kg^-1） group， Banxia Xiexintang （9.1 g·kg^-1） group， Xinkai （3.19 g·kg^-1） group， Kujiang （1.82 g·kg^-1） group， and Ganbu （4.1 g·kg^-1） group， with 10 rats in each group. Except the blank group， the other groups were given mixed antibiotics by gavage to induce intestinal flora disorder. After 14 days， the rats in different drug groups were administrated with corresponding drugs by gavage， and those in the blank group and model group with the same amount of normal saline once a day for 14 days. After that， fecal samples were collected aseptically for 16S rDNA sequencing of intestinal flora， and lipopolysaccharide （LPS， 10 mg·kg^-1） was injected intraperitoneally to induce inflammatory reaction. The tissue morphology of colonic mucosa was observed via hematoxylin-eosin （HE） staining， and the macrophage infiltration of colonic mucosa was observed via toluidine blue staining and immunohistochemistry. The expression of interleukin-1β （IL-1β）， interleukin-6 （IL-6）， interleukin-8 （IL-8）， tumor necrosis factor-α （TNF-α）， and interleukin-10 （IL-10） mRNA were determined by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultCompared with the blank group， the modeling changed the intestinal flora structure of the young rats （P<0.01）， damaged the colonic mucosa， reduced the macrophage infiltration， and down-regulated the mRNA levels of IL-1β， IL-6， IL-8， TNF-α， and IL-10 （P<0.01）. Compared with the model group， bifidobacterium quadruple viable tablets， Banxia Xiexintang and its disassembled prescriptions increased the diversity of intestinal flora and the relative abundance of beneficial bacteria such as Bacteroidetes and Firmicutes （P<0.01）. At the same time， they ameliorated colonic mucosal injury （P<0.05， P<0.01）， increased macrophage infiltration （P<0.05， P<0.01）， and up-regulated the mRNA levels of IL-6， IL-8， and TNF-α （P<0.01）. The mRNA level of IL-1β was up-regulated in Bifidobacterium tetralogy viable tablets， Banxia Xiexintang， Kujiang， and Ganbu groups （P<0.01）， and that of IL-10 was up-regulated in Bifidobacterium tetralogy viable tablets， Banxia Xiexintang， Xinkai， and Ganbu groups （P<0.01）. ConclusionBanxia Xiexintang and the disassembled prescriptions can adjust the intestinal flora of young rats exposed to antibiotics and protect the immune barrier of colonic mucosa after intestinal flora disorder. In particularly， the whole prescription of Banxia Xiexintang demonstrates the best performance.

Objective: To evaluate the recognition of acute respiratory infection (ARI) by a pretrained model based on electronic medical records (EMRs). Methods: 38 581 EMRs were obtained from Chongqing University Three Gorges Hospital in December 2021. Bidirectional encoder representation from transformers (BERT) pretrained model was used to identify ARI in EMRs. The results of medical professionals were considered as the gold standard to calculate the sensitivity, specificity, Kappa value, and area under the curve of the receiver operating characteristic (AUC). Results: There were 3 817 EMRs in the test set, with 1 200 ARIs. A total of 1 205 cases were determined as ARI by the model, with a sensitivity of 92.67% (1 112/1 200) and a specificity of 96.45% (2 524/2 617). The model identified ARI with similar accuracy in males and females (AUCs 0.95 and 0.94, respectively), and was more accurate in identifying ARI cases in those aged less than 18 than in adults 18-59 and adults 60 and older (AUCs 0.94, 0.89 and 0.94, respectively). The current model had a better identification of ARIs in outpatient patients than that in hospitalized patients, with AUCs of 0.74 and 0.95, respectively. Conclusion: The use of the BERT pretrained model based on EMRs has a good performance in the recognition of ARI cases, especially for the outpatients and juveniles. It shows a great potential to be applied to the monitoring of ARI cases in medical institutions.
