Inhibiting the death receptor 3(DR3)signaling pathway in group 3 innate lymphoid cells(ILC3s)pre-sents a promising approach for promoting mucosal repair in individuals with ulcerative colitis(UC).Paeoniflorin,a prominent component of Paeonia lactiflora Pall.,has demonstrated the ability to restore barrier function in UC mice,but the precise mechanism remains unclear.In this study,we aimed to delve into whether paeoniflorin may promote intestinal mucosal repair in chronic colitis by inhibiting DR3 signaling in ILC3s.C57BL/6 mice were subjected to random allocation into 7 distinct groups,namely the control group,the 2%dextran sodium sulfate(DSS)group,the paeoniflorin groups(25,50,and 100 mg/kg),the anti-tumor necrosis factor-like ligand 1A(anti-TL1A)antibody group,and the IgG group.We detected the expression of DR3 signaling pathway proteins and the proportion of ILC3s in the mouse colon using Western blot and flow cytometry,respectively.Meanwhile,DR3-overexpressing MNK-3 cells and 2% DSS-induced Rag1-/-mice were used for verification.The results showed that paeoniflorin alleviated DSS-induced chronic colitis and repaired the intestinal mucosal barrier.Simultaneously,paeoniflorin inhibited the DR3 signaling pathway in ILC3s and regulated the content of cytokines(interleukin-17A,granulocyte-macrophage colony stimulating factor,and interleukin-22).Alternatively,paeoniflorin directly inhibited the DR3 signaling pathway in ILC3s to repair mucosal damage indepen-dently of the adaptive immune system.We additionally confirmed that paeoniflorin-conditioned me-dium(CM)restored the expression of tight junctions in Caco-2 cells via coculture.In conclusion,paeoniflorin ameliorates chronic colitis by enhancing the intestinal barrier in an ILC3-dependent manner,and its mechanism is associated with the inhibition of the DR3 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.

ObjectiveTo investigate the mechanism of salvianolic acid F (Sal F) in repairing the high glucose-induced injury in human kidney-2 (HK-2) cells via the B-cell lymphoma-2 (Bcl-2)-associated X protein (Bax)/cysteinyl aspartate-specific proteinase 3 (Caspase-3)/gasdermin-E (GSDME) pathway. MethodThe cell counting kit-8 (CCK-8) was used to measure the relative viability of HK-2 cells exposed to high glucose and different concentrations (2.5, 5, 10, 20 μmol·L-1) of Sal F and the relative viability of HK-2 cells treated with Sal F for different time periods. The levels of lactate dehydrogenase (LDH) and interleukin-1β (IL-1β) in the supernatant of the cell culture were measured by the LDH assay kit and enzyme-linked immunosorbent assay (ELISA) kit, respectively. Flow cytometry combined with Annexin V-FITC/propidium iodide (PI) and Hoechst 33342/PI staining was employed to reveal the proportion of PI-positive HK-2 cells exposed to high glucose. Western blotting was employed to determine the protein levels of Bax, Bcl-2, cytochrome C, cysteinyl aspartate-specific proteinase (Caspase)-9, Caspase-3, and GSDME in the HK-2 cells exposed to high glucose and treated with Sal F. The 2,7-dichlorodihydrofluorescein diacetate fluorescence probe (DCFH-DA) and mitochondrial membrane potential assay kit (JC-1) were used to determine the production of reactive oxygen species (ROS) and the mitochondrial membrane potential in the HK-2 cells exposed to high glucose and treated with Sal F. ResultCompared with the blank group, the model group showed decreased cell viability (P<0.01), elevated levels LDH and IL-1β, increased proportion of PI-positive cells (P<0.01), up-regulated protein levels of Bax, cytochrome C, Caspase-9, Caspase-3, and GSDME (P<0.01), down-regulated protein level of Bcl-2 (P<0.01), decreased mitochondrial membrane potential, and excessive ROS accumulation. Compared with the model group, Sal F repaired the high glucose-induced injury in HK-2 cells (P<0.05), lowered the levels of LDH and IL-1β (P<0.05, P<0.01), and decreased the proportion of PI-positive cells (P<0.01). In addition, Sal F down-regulated the protein levels of Bax, cytochrome C, Caspase-9, Caspase-3, and GSDME and up-regulated the protein level of Bcl-2 (P<0.05, P<0.01), increased the mitochondrial membrane potential, and decreased the accumulation of ROS in HK-2 cells. ConclusionSal F can reduce the production of ROS, restore the balance of mitochondrial membrane potential, and inhibit pyroptosis via the Bax/Caspase-3/GSDME signaling pathway to repair the high glucose-induced injury in HK-2 cells.

OBJECTIVE To analyze the metabolites of Zhideke granules and speculate its metabolic pathway in rats in vivo. METHODS Male SD rats were randomly divided into blank group and administration group (Zhideke granules, 9.45 g/kg); they were given ultrapure water or relevant medicine, twice a day, every 6-8 h, for 3 consecutive days. Serum, urine and feces samples of rats were collected, and their metabolites were identified by UPLC-Q-Exactive-MS technique after intragastric administration of Zhideke granules; their metabolic pathways were speculated. RESULTS After intragastric administration of Zhideke granules, 16 prototype components (i.g. irisflorentin, baicalin, chlorogenic acid) and 11 metabolites (i.g. hydration products of kaempferol or luteolin, methylation products of chlorogenic acid, and hydroxylation products of baicalin) were identified in serum, urine and feces of rats. Among them, 8 prototype components and 4 metabolites were identified in serum samples; 10 prototype components and 7 metabolites were identified in urine samples; 8 prototype components and 5 metabolites were identified in the fecal samples. CONCLUSIONS The metabolites of Zhideke granules in rats mainly include baicalin, irisflorentin,chlorogenic acid, and the main metabolic pathways included methylation, hydroxylation, glucuronidation.

ObjectiveTo investigate the effect of Yishen Tongluo prescription (YSTLP) on apoptosis of renal tubular epithelial cells and explore the mechanism based on endoplasmic reticulum stress pathway of protein kinase R-like endoplasmic reticulum kinase (PERK)/activating transcription factor 4 (ATF4)/transcription factor C/EBP homologous protein (CHOP). MethodThe db/db mice were randomly divided into model group, valsartan group (10 mg·kg-1), and low, middle, high-dose YSTLP groups (1, 2.5, 5 g·kg-1). Samples were collected after eight weeks of drug intervention. In addition, db/m mice in the same litter served as the control group. Human renal tubular epithelial cells (HK-2) were cultured in vitro and divided into the control group, advanced glycated end-product (AGE) group, and AGE + low, middle, and high-dose YSTLP groups (100, 200, 400 mg·L-1). TdT-mediated dUTP nick end labeling (TUNEL) staining was used to detect the apoptosis rate of HK-2 cells. Methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay was conducted to detect the viability of HK-2 cells. Calcium fluorescence probe staining and luciferase reporter gene method were adopted to detect the luciferase activity of folded protein response element (UPRE) and endoplasmic reticulum stress. Immunohistochemical (IHC) analysis was carried out to measure the protein expressions of phosphorylated PKR (p-PERK), CHOP, and ATF4. Real-time polymerase chain reaction (Real-time PCR) was used to measure the mRNA expression levels of CHOP and X-box binding protein 1 (XBP1) in mouse kidney and HK-2 cells. Western blot was used to detect the protein expression level of p-PERK, PERK, CHOP, ATF4, B-cell lymphoma-2 (Bcl-2), Bcl-2 associated X protein (Bax), and cleaved Caspase-3 in mouse kidney and HK-2 cells. ResultIn the cellular assay, HK-2 cell viability was significantly reduced, and the apoptosis rate was elevated in the AGE group compared with the control group (P<0.01). The mRNA and protein expression levels of apoptosis-related factor Bcl-2 were significantly reduced (P<0.01), and those of Bax were significantly increased (P<0.01). The protein expression level of cleaved Caspase-3 was significantly increased (P<0.01). Compared with the AGE group, YSTLP administration treatment resulted in elevated cell viability and reduced apoptosis rate (P<0.01). The mRNA and protein expression levels of Bcl-2 were significantly elevated in a time- and dose-dependent manner (P<0.01), and those of Bax were significantly reduced in a time- and dose-dependent manner. The protein expression level of cleaved Caspase-3 was significantly reduced in a time- and dose-dependent manner (P<0.01). The intracellular Ca2+ imbalance and UPRE luciferase fluorescence intensity were increased in the AGE group compared with the control group (P<0.01). The mRNA levels of endoplasmic reticulum stress-related factors CHOP and XBP1 were significantly increased (P<0.01), and the protein expression levels of p-PERK, CHOP, and ATF4 were significantly increased (P<0.05). Compared with the AGE group, YSTLP effectively improved intracellular Ca2+ imbalance in HK-2 cells and decreased UPRE luciferase fluorescence intensity in a dose-dependent manner (P<0.01). It reduced the mRNA levels of endoplasmic reticulum stress-related factors CHOP and XBP1 (P<0.01) and the protein expression levels of intracellular p-PERK, CHOP, and ATF4 in a dose- and time-dependent manner (P<0.01). In animal experiments, the protein expression level of Bcl-2 was significantly reduced(P<0.01), and that of cleaved Caspase-3 and Bax was significantly increased in the model group compared with the control group (P<0.05). The protein expression level of Bcl-2 was dose-dependently elevated, and that of cleaved Caspase-3 and Bax was dose-dependently decreased in the YSTLP groups compared with the model group (P<0.01). Compared with the control group, the mRNA expression levels of CHOP and XBP1 were significantly elevated in the model group (P<0.05, P<0.01), and the protein expression levels of p-PERK, CHOP, and ATF4 were significantly increased (P<0.05). Compared with the model group, YSTLP significantly decreased the mRNA expression levels of CHOP and XBP1 (P<0.01) and the protein expression levels of p-PERK, CHOP, and ATF4 (P<0.01). ConclusionYSTLP can effectively inhibit endoplasmic reticulum stress and improve apoptosis of renal tubular epithelial cells, and its mechanism may be related to the regulation of the PERK/AFT4/CHOP pathway.

To explore the thinking and working mode of clinical pharmacists of traditional Chinese medicine participating in clinical,the drug treatment was analyzed by an acute hyperkalemia patient suspected of CKD 5 caused by traditional Chinese medicine.This case is a CKD 5 patient.Since proteinuria was found for 8 years,bilateral lower limb edema was intermittent for 4 years,and the recurrence was aggravated for 1 week,the patient was admitted to the hospital.In the Department of Traditional Chinese Medicine,the patient received standard and reasonable antiplatelet,lipid regulation,kidney protection,anemia improvement,blood pressure reduction,and heart load reduction,Traditional Chinese medicine decoction,traditional Chinese patent medicines.The patient's condition improved,but the newly emerging hyperkalemia prolonged the patient's hospital stay.After the treatment of blood potassium lowering drugs,the blood potassium still increased repeatedly.For this reason,clinical Chinese pharmacists assisted clinicians to find out the factors that caused the repeated increase of blood potassium in combination with existing domestic and foreign literature.Finally,considering the high possibility of traditional Chinese medicine,they stopped using traditional Chinese medicine and continued to use blood potassium lowering drugs,and the blood potassium returned to normal.Hyperkalemia caused by traditional Chinese medicine is not common in clinical practice and often is ignored.It can be seen that clinical pharmacists can participate in pharmaceutical care to find adverse drug reactions as soon as possible and ensure the safety of drug use.

Objective:To analyze the value of the modified 5-factor frailty index in assessing postoperative complications and mortality in elderly hip fracture patients.Methods:In this retrospective study, clinical data were collected of hip fracture patients aged 60 years and above surgically treated at Beijing Luhe Hospital affiliated to Capital Medical University between January 2015 and December 2019.Patients' group assignment was based on whether the modified frailty index score was ≤1 or ≥2, and a post-surgery follow-up was conducted for survival at 30 days, 1 year, 2 years, and 4 years, which was analyzed by the Kaplan-Meier method.Multivariate Cox regression analysis was used to identify factors affecting death in elderly patients.Results:A total of 1 208 patients were included, with 890 in the group with the index score ≤1 and 318 in the group with the index score ≥2.There was no difference in mortality at 30 days(1.6% or 14/890 vs.1.9% or 6/318, P=0.707), 1-year(11.3% or 99/874 vs.11.6% or 36/310, P=0.917), 2-years(19.7% or 168/852 vs.24.3% or 73/300, P=0.099)and 4-years(44.0% or 238/541 vs.51.5% or 106/206, P=0.071). The incidence of postoperative complications in the group with the score ≥2 was higher(14.8% or 47/318 vs.9.7% or 86/890, P=0.012), including the incidence of stroke(6.3% or 20/318 vs.1.8% or 16/890, P<0.001)and the incidence of postoperative pneumonia(6.0% or 19/318 vs.3.1% or 28/890, P=0.029), and the differences were statistically significant.Multivariate Cox regression analysis showed that age, being female, the Charlson comorbidity index score and low hemoglobin at admission were risk factors for 1-year, 2-year and 4-year mortality post-surgery(all P<0.05), while the modified frailty index score had no correlation with postoperative mortality. Conclusions:A modified frailty index ≥2 is predictive of increased risk of postoperative pneumonia and stroke in patients with hip fractures, but is not correlated with the risk of postoperative mortality.

OBJECTIVE
To explore the pharmacodynamic related substances and mechanism of Weining San(WNS) against gastric ulcer(GU) according to fingerprint and network pharmacology.
METHODS
Twelve batches of WNS fingerprints were established by HPLC, and methodological investigation was carried out. Combined with reference substances, characteristic peaks were identified, pharmacodynamic related substances were screened, and network pharmacological analysis was carried out. Using TCMIP and Swiss Target Prediction database to retrieve component targets; Using OMIM, GeneCards and Drugbank databases to retrieve GU disease targets, taking the intersection targets of components and diseases, using String database to construct protein-protein interaction network diagram, and analyzing topological parameters; Using Cytoscape 3.8.2 software to construct "component-disease-target" network diagram; GO and KEGG enrichment analysis of intersection targets were carried out by Metascape website. Then the alcoholic GU mouse model was established by intragastric administration of absolute ethanol to verify the results of network pharmacology prediction. RESUITS The precision, stability and repeatability of HPLC fingerprint method were good. By comparison and comprehensive analysis of control substances, notoginsenoside R1, ginsenoside Rg1, militarine, ginsenoside Rb1, schisandrin, schisandrol B, deoxyschizandrin and schisantherin A were identified as pharmacodynamic related substances in WNS, which may play their role by regulating core targets such as AKT1, IL-6, STAT3, TNF, IL1B and key signal pathways such as PI3K-Akt and JAK-STAT. The gastric ulcer index, ulcer inhibition rate and HE staining showed that WNS could improve gastric mucosal injury in GU mice. The results of ELISA, WST-1 and TBA showed that WNS could decrease the levels of TNF-α, IL-6, IL-1β and MDA, and increase the levels of SOD and PGE2, suggesting that the anti-GU effect of WNS was related to the inhibition of inflammatory reaction and oxidative stress mechanism, which further verified the prediction of network pharmacology.
CONCLUSION
This study combines fingerprint analysis, network pharmacology, and animal experimental validation to explore the pharmacodynamic related substances and mechanisms of WNS anti-GU efficacy, providing reference for quality control and clinical research of WNS.
