ObjectiveTo clarify the anti-inflammatory and lung-protective effects of Yantiao prescription on lipopolysaccharide (LPS)-induced acute lung injury (ALI), and to explore the impact of Yantiao prescription on the metabolic pathways of arachidonic acid (AA) in vivo. MethodsThirty male C57BL/6J mice were randomly divided into the following groups based on body weight: normal group, model group, dexamethasone group (2 mg·kg-1), low-dose Yantiao prescription group (18 g·kg-1), and high-dose Yantiao prescription group (36 g·kg-1), with 6 mice in each group. The ALI mouse model was established by intraperitoneal injection of LPS. The treatment groups received oral gavage once a day for 7 consecutive days, and serum and lung tissue were collected at the end of the experiment. The content of pro-inflammatory cytokines tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in serum was detected by enzyme-linked immunosorbent assay (ELISA). Hematoxylin-eosin (HE) staining was used to assess lung tissue pathology. The wet/dry weight ratio (W/D) and myeloperoxidase (MPO) activity in lung tissue were measured. The content of AA metabolites in serum and lung tissue was measured by liquid chromatography triple quadrupole-mass spectrometry (LC-MS/MS). ResultsCompared with the conditions in the normal group, the content of serum pro-inflammatory cytokines TNF-α, IL-1β, and IL-6 in the model group was significantly increased (P<0.01). The alveolar structure in mice was severely damaged, with markedly thickened alveolar walls and extensive inflammatory cell infiltration. The W/D ratio and MPO activity in lung tissue were significantly increased (P<0.01). The content of AA metabolites, including prostaglandin D2 (PGD2), prostaglandin E2 (PGE2), 11(S)-hydroxy-eicosatetraenoic acid [11(S)-HETE], and 5-hydroxy-eicosatetraenoic acid (5-HETE) in serum and lung tissue was significantly increased (P<0.05), while the content of 11,12-epoxyeicosatrienoic acid (11,12-EET) and 14,15-epoxyeicosatrienoic acid (14,15-EET) in serum was significantly decreased (P<0.01). Compared with the results in the model group, the content of serum pro-inflammatory cytokines TNF-α, IL-1β, and IL-6 in the dexamethasone group, low-dose Yantiao prescription group, and high-dose Yantiao prescription group was significantly reduced (P<0.05). Mild thickening of alveolar walls, scattered inflammatory cell infiltration, and relatively intact tissue structure with improved alveolar architecture were observed. The W/D ratio and MPO activity in lung tissue were significantly reduced (P<0.01). The content of AA metabolites PGD2, PGE2, 11(S)-HETE, and 5-HETE in serum from the dexamethasone group was significantly decreased (P<0.05), while the content of 14,15-EET in serum significantly increased (P<0.01), and the content of 5-HETE in lung tissue significantly decreased (P<0.01). In the low-dose and high-dose Yantiao prescription groups, the content of AA metabolites PGD2, PGE2, 11(S)-HETE, and 5-HETE in serum and lung tissue was significantly decreased (P<0.05), while the content of 11,12-EET in both serum and lung tissue was significantly increased (P<0.05). ConclusionYantiao prescription has significant protective effects against LPS-induced ALI, which are related to its regulation of AA metabolic pathways in vivo.

ObjectiveTo investigate the contamination status, transmission risk and drug resistance of Klebsiella pneumoniae (KP) on the object surfaces in the surrounding environment of hospitalized patients infected with carbapenem-resistant Klebsiella pneumoniae (CRKP) , so as to provide a scientific guidance for the prevention and control of healthcare-associated infection. MethodsSamples from the surfaces of objects in the surrounding environment of CRKP infected patients living in the intensive care unit (ICU) and hand specimens from healthcare workers were collected for KP isolation and identification, as well as drug susceptible test in a medical institution located in Minhang District, Shanghai from 2021 to 2023. Additionally, both univariate and multivariate logistic regression analyses were used to identify the influencing factors associated with KP contamination in the hospital environment. ResultsA total of 546 surface samples were collected from the surrounding environment objects of 15 patients infected with CRKP, with a KP detection rate of 6.59% (36/546).The KP detection rate in the ICU of general ward (10.22%) was higher than that in the ICU of emergency department (2.94%) (χ2=12.142, P<0.001). Moreover, the KP detection rate on the surfaces of patient-contacted items (15.66%) was higher than that on shared-use items (6.25%), cleaning items (10.00%), and medical supplies (3.30%) (χ2=17.943, P<0.001). Besides, the detection rate of KP in items sent out of hospital for disinfection (15.38%) was higher than that in those self-disinfected (4.20%) (χ2=19.996, P<0.001).The highest detection rate of KP was observed in high-temperature washing (15.13%, 18/119) (χ2=21.219, P<0.001), while the lowest detection rate was observed in antibacterial hand sanitizer with trichlorohydroxydiphenyl ether sanitizing factor (0, 0/60) ( χ2=21.219, P<0.001).The detection rate of KP in samples taken more than 24 hours after the last disinfection (23.08%) was higher than that in those taken at 4 to24 hours (12.90%) and less than 4 hours (4.22%) (χ2=23.398,P<0.001).ICU of general ward (OR=4.045, 95%CI: 2.206‒7.416), patient-contacted items (OR=3.113, 95%CI: 1.191‒8.141), and self-disinfection ( OR=0.241, 95%CI:0.144‒0.402) were influencing factors for KP contamination in environmental surface. From 2021 to 2023, the drug resistance rates of hospital environmental KP isolates showed an upward trend (P<0.001) to antibiotics such as ceftazidime and gentamicin. Furthermore, high drug resistance rates of KP (>90%) were observed to ciprofloxacin, levofloxacin, cefotaxime, ceftriaxone, and cefepime. ConclusionCRKP can be transmitted outward through the surfaces of objects in the patients’ surroundings, and the drug resistance situation is severe. In clinical settings, it is necessary to implement isolation measures for CRKP infection patients, to increase the frequency of disinfection for objects in their surroundings, to strengthen hand hygiene practices, and to use antibiotics appropriately.

OBJECTIVE To evaluate the effectiveness and safety of warfarin anticoagulation therapy guided by gene test in patients undergoing left ventricular assist device (LVAD) implantation, and to analyze the influencing factors of warfarin anticoagulation efficacy. METHODS Patients who underwent LVAD implantation at the Heart and Vascular Center of Northern Jiangsu People’s Hospital from January 2023 to October 2024 and required warfarin anticoagulant therapy were selected as the study subjects. They were divided into genetic testing group (n=51) and empirical treatment group (n=17) based on whether they underwent CYP2C9 and VKORC1 gene test. The gene test group was given warfarin based on the predicted dose calculated by gene test, while the empirical treatment group was given warfarin by clinical doctors based on international normalized ratio (INR) experience, all patients were given warfarin once a day. Follow-up observation was conducted for 6 months to compare the effectiveness [time in therapeutic range(TTR), the time required to reach INR for the first time, the incidence of embolic events, the incidence of INR<1.5 events] and safety (the incidence of major and minor bleeding events,the incidence of INR>3.5 events) of warfarin treatment between two groups of patients. According to whether the patient’s TTR was ≥60%, they were divided into TTR≥60% group (n=20) and TTR<60% group (n=48). Univariate and multivariate binary Logistic regression analysis were used to determine the factors affecting the anticoagulant effect of warfarin in patients. RESULTS The TTR of patients in the gene test group was significantly higher than that in the empirical treatment group (P<0.05). The incidence of INR<1.5 events in the gene test group was significantly lower than in the empirical treatment group (P<0.05). The incidence of minor bleeding events and INR>3.5 events in the gene test group were lower than in the empirical treatment group, but the difference was not statistically significant (P>0.05). The results of multivariate binary Logistic regression analysis showed that gene test was an independent protective factor for warfarin anticoagulant therapy [odds ratio (OR)=10.842, 95% confidence interval (CI): 1.211-27.037, P=0.033], and the combination of statins was an independent risk factor for warfarin anticoagulant therapy [OR=0.196, 95%CI: 0.045-0.861, P=0.031]. CONCLUSIONS Under the guidance of gene test, warfarin anticoagulation therapy for LVAD patients after implantation can improve TTR, shorten the anticoagulation target time, and has good safety; meanwhile, it should be noted that the combination of statins may enhance the anticoagulant effect of warfarin, thereby increasing the risk of bleeding in patients.

Acute pancreatitis (AP) is a common clinical acute abdominal disease, which is characterized by acute onset, rapid development, severe disease, many complications, and high mortality rate. It can progress to severe AP (SAP) if not treated promptly in the early stage. The pathogenesis of AP is complex and involves multiple cellular and molecular levels. It is now clear that oxidative stress and reactive oxygen species (ROS) production are involved in the physiopathological process of AP, which is associated with a low quantity and activity of antioxidant enzymes in pancreatic cells. Nuclear factor E2-related factor 2 (Nrf2) serves as the ''golden key'' to maintain redox homeostasis in tissue cells and constitutes an important signaling pathway for antioxidant response and inflammation in vivo by collaborating with downstream antioxidant enzymes such as heme oxygenase-1 (HO-1). Traditional Chinese medicine has unique efficacy in treating diseases due to its multi-component, multi-target, multi-drug delivery, and multi-formulation characteristics. Based on the concept of synergy between traditional Chinese and Western medicine, traditional Chinese medicine is becoming a new craze in the treatment of AP. The level of oxidative stress and Nrf2/HO-1 signaling pathway in AP pancreatic tissue are in a dynamic change process, and the intervention of traditional Chinese medicine can clean ROS production, affect the inflammatory pathway, and reduce oxidative stress damage, so as to protect against pancreatic injury. This suggests that this pathway plays an important role in AP. This article reviews the recent literature on the regulation of the Nrf2/HO-1 signaling pathway by traditional Chinese medicine for AP and summarizes that the monomers of traditional Chinese medicine targeting this pathway are mainly heat-clearing and detoxifying, blood-activating and blood-stasis-removing, and Qi benefiting and middle warming, and the compounds of traditional Chinese medicine include Yinchenhao Decoction and QingYi Ⅱ, so as to provide a new direction for the prevention and treatment of AP and further drug development.

Objective:
To explore and validate the potential targets of Paeoniae Radix Alba (P. Radix, Bai Shao) in protecting against chemical liver injury through network pharmacology, molecular docking technology, and in vitro cell experiments.
Methods:
Network pharmacology was used to identify the common potential targets of P. Radix and chemical liver injury. Molecular docking was used to fit the components, which were subsequently verified in vitro. A cell model of hepatic fibrosis was established by activating hepatic stellate cell (HSC)-LX2 cells with 10 ng/mL transforming growth factor-β1. The cells were exposed to different concentrations of total glucosides of paeony (TGP), the active substance of P. Radix, and then evaluated using the cell counting kit-8 assay, enzyme-linked immunosorbent assay, and western blot.
Results:
Analysis through network pharmacology revealed 13 key compounds of P. Radix, and the potential targets for preventing chemical liver injury were IL-6, AKT serine/threonine kinase 1, jun proto-oncogene, heat shock protein 90 alpha family class A member 1 (HSP90AA1), peroxisome proliferator activated receptor gamma (PPARG), PTGS2, and CASP3. Gene Ontology (GO) enrichment analysis indicated the involvement of response to drugs, membrane rafts, and peptide binding. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed that the main pathways involved lipid and atherosclerosis and chemical carcinogenesis-receptor activation. Paeoniflorin and albiflorin exhibited strong affinity for HSP90AA1, PTGS2, PPARG, and CASP3. Different concentrations of TGP can inhibit the expression of COL-Ⅰ, COL-Ⅲ, IL-6, TNF-α, IL-1β, HSP-90α, and PTGS2 while increasing the expression of PPAR-γ and CASP3 in activated HSC-LX2 cells.
Conclusion
P. Radix primarily can regulate targets such as HSP90AA1, PTGS2, PPARG, CASP3. TGP, the main active compound of P. Radix, protects against chemical liver injury by reducing the inflammatory response, activating apoptotic proteins, and promoting the apoptosis of activated HSCs.
