Objective:To explore the molecular mechanism of TCM compound Shengxue Tongbian Granules in improving intestinal injury in septic rats through bioinformatics and experimental validation methods.Methods:The GSE131761 gene set was processed by bioinformatics to screen differential genes, then weighted gene co-expression network analysis (WGCNA) was applied to screen modular genes. The intersection of modular genes and differential genes was taken, and finally, the least absolute shrinkage and selection operator (LASSO) technique was applied to further obtain the key targets of sepsis, which was validated by experiments. Totally 72 SD rats were divided into sham-operation group, model group, dexamethasone group (0.15 mg/kg), Shengxue Tongbian Granules low- (0.3 g/kg), medium- (0.6 g/kg), and high-dosage (1.2 g/kg) groups, with 12 rats in each group. Corresponding drug interventions were administered to each treatment group before and 12 hours after modeling. The sham-operation group and the model group were gavaged daily with equal amounts of saline. Samples were collected after 24 hours. HE staining was used to detect the pathological morphology of intestinal tissues in each group of rats; ELISA was used to detect the levels of TNF-α, diamine oxidase (DAO), IL-6, IL-10, and myeloperoxidase (MPO) in rat serum. Immunohistochemistry was used to detect the protein expressions of MPO and neutrophil elastase (NE/LANE) in intestinal tissue, and Western blot was used to detect the protein expression of peptidyl arginine deaminase (PAD4) in intestinal tissue.Results:Seven final key genes related to sepsis were selected, namely ANXA3, CYP1B1, FCAR, LILRA5, PADI4, NOV, and S100A12. Experimental results showed that drug administration alleviated intestinal injury; compared with the model group, the levels of TNF-α, IL-6, MPO, and DAO decreased in the Shengxue Tongbian Granules high-dosage group ( P<0.05), the levels of ELANE and MPO were reduced in Shengxue Tongbian Granules low-, medium-, and high-dosage groups ( P<0.05), and PAD4 expression was reduced in the Shengxue Tongbian Granules high-dosage group ( P<0.05). Conclusion:Shengxue Tongbian Granules can improve the intestinal injury of septic rats, and the mechanism may be related to the inhibition of PAD4-mediated formation of NETs and the improvement of inflammatory response.

Objective:To investigate the effects of hepatic fatty acid transporter 5 (FATP5) gene expression on the levels of free long-chain fatty acid (LCFA) in mice with metabolic associated fatty liver disease (MAFLD).Methods:From June to December 2022, a prospective study was conducted with three experimental groups: wild-type (WT) group, FATP5 gene expression negative (FATP5 -) group, and human FATP5 gene expression positive (hFATP5 +) group, with 10 mice in each group. Each group of mice was fed a high-fat diet for 16 weeks to establish a model of MAFLD. Hepatic tissue changes were observed using hematoxylin-eosin staining. The liver mass and liver coefficient of the mice were measured. Total cholesterol (TC), triglycerides (TG), aspartate aminotransferase (AST), alanine aminotransferase (ALT), uric acid (UA), and LCFA levels were determined using an automatic biochemical analyzer. Blood glucose (Glu) levels were measured using a blood glucose analyzer. The liver mass and liver coefficient, TC and TG levels, AST and ALT levels, Glu and UA levels, and LCFA levels were compared among the three groups. Results:In the WT group, there was significant inflammatory cell infiltration within the hepatocytes and a large amount of fat accumulation. In the FATP5 - group, the inflammatory cell infiltration in the hepatocytes was mild with slight fat accumulation. In the hFATP5 + group, the inflammatory cell infiltration in the hepatocytes was severe, with great fat accumulation. The liver mass [(1.27 ± 0.25) g], liver coefficient (2.38 ± 0.19), TC [(1.82 ± 0.26) mmol/L], TG [(0.93 ± 0.24) mmol/L], AST [(169.95 ± 37.73) U/L], ALT [(95.36 ± 21.49) U/L], Glu [(8.34 ± 1.52) mmol/L], and UA [(74.32 ± 15.52) μmol/L] in the FATP5 - group were all significantly lower than those in the WT group [(1.61 ± 0.23) g, (2.71 ± 0.20), (2.31 ± 0.28) mmol/L, (1.34 ± 0.21) mmol/L, (278.31 ± 43.24) U/L, (147.32 ± 28.81) U/L, (10.52 ± 1.24) mmol/L, (96.28 ± 17.43) μmol/L], while the LCFA level [(3.57 ± 0.48) mg/L] in the FATP5 - group was significantly higher than that in the WT group [(2.63 ± 0.56) mg/L] ( t = 3.17, 3.78, 4.06, 4.07, 5.97, 4.57, 3.51, 2.98, 4.03, all P < 0.05). In the hFATP5 + group, the liver mass [(1.92 ± 0.30) g], liver coefficient (2.95 ± 0.23), TC [(2.59 ± 0.24) mmol/L], TG [(1.76 ± 0.35) mmol/L], AST [(341.22 ± 48.98) U/L], ALT [(189.45 ± 17.97) U/L], Glu [(13.21 ± 1.98) mmol/L], and UA [(117.74 ± 18.38) μmol/L] were all significantly higher than those in the WT group, while the LCFA level [(3.57 ± 0.48) mg/L] in the FATP5 + group was significantly lower than that in the WT group ( t = 2.59, 2.49, 2.40, 3.25, 3.04, 3.92, 3.64, 2.68, 3.19, all P < 0.05). Conclusions:The absence of FATP5 in the liver can elevate blood levels of LCFA in mice with MAFLD, reduce food intake, and help alleviate the symptoms of MAFLD.

Intelligent responsive drug delivery system opens up new avenues for realizing safer and more effective combination immunotherapy. Herein, a kind of tumor cascade-targeted responsive liposome (NLG919@Lip-pep1) is developed by conjugating polypeptide inhibitor of PD-1 signal pathway (AUNP-12), which is also a targeted peptide that conjugated with liposome carrier through matrix metalloproteinase-2 (MMP-2) cleavable peptide (GPLGVRGD). This targeted liposome is prepared through a mature preparation process, and indoleamine-2,3-dioxygenase (IDO) inhibitor NLG919 was encapsulated into it. Moreover, mediated by the enhanced permeability and retention effect (EPR effect) and AUNP-12, NLG919@Lip-pep1 first targets the cells that highly express PD-L1 in tumor tissues. At the same time, the over-expressed MMP-2 in the tumor site triggers the dissociation of AUNP-12, thus realizing the precise block of PD-1 signal pathway, and restoring the activity of T cells. The exposure of secondary targeting module II VRGDC-NLG919@Lip mediated tumor cells targeting, and further relieved the immunosuppressive microenvironment. Overall, this study offers a potentially appealing paradigm of a high efficiency, low toxicity, and simple intelligent responsive drug delivery system for targeted drug delivery in breast cancer, which can effectively rescue and activate the body's anti-tumor immune response and furthermore achieve effective treatment of metastatic breast cancer.

Objective:To analyze the diagnostic and prognostic value of routine bone marrow examination in patients with extranodal NK/T-cell lymphoma (ENKTCL) based on PET-CT staging.Methods:Clinical data of 186 patients who received bone marrow biopsy and bone marrow aspiration in Fujian Medical University Union Hospital from 2013 to 2021 were retrospectively analyzed. All patients were divided into bone marrow biopsy + bone marrow aspiration group ( n=186) and PET-CT + bone marrow biopsy group ( n=139). The sensitivity, specificity, positive and negative predictive values were compared between two groups. The data were analyzed and plotted. Survival analysis was performed using Kaplan-Meier method and log-rank test. Results:In the whole cohort, 45 patients were positive for bone marrow biopsy, and 30 of them were positive for bone marrow aspiration. A total of 141 patients who were negative for bone marrow biopsy also achieved negative results for bone marrow aspiration. A total of 139 patients completed PET-CT staging and bone marrow biopsy. And 30 patients were diagnosed with positive bone marrow by PET-CT, in which 22 of them were confirmed positive by bone marrow biopsy. Among 109 patients diagnosed with negative bone marrow by PET-CT, 5 of them were confirmed positive by bone marrow biopsy. All these cases were classified as stage Ⅳ due to distant metastases. PET-CT had a diagnostic sensitivity of 81.5%, a specificity of 92.9%, a positive predictive value of 73.3%, and a negative predictive value of 95.4%. Among early stage (Ⅰ-Ⅱ stage) patients diagnosed with PET-CT, all of them were negative for bone marrow biopsy (the negative predictive value was 100%). In stage Ⅳ patients ( n=55), the 1-year overall survival of patients with bone marrow involvement by bone marrow biopsy or PET-CT ( n=35) compared with their counterparts with the involvement of other organs ( n=20) was 28.7% vs.42.0% ( P=0.13), and 1-year progression free survival rates was 23.2% vs. 23.3% in ( P=0.94). Conclusions:Routine bone marrow biopsy does not change the original staging of patients with early stage ENKTCL based on PET-CT staging. Advanced stage patients with positive bone marrow biopsy tend to obtain worse prognosis, indicating that bone marrow biopsy still has certain value.

Objective To investigate the risk factors for covert hepatic encephalopathy (CHE) in patients with liver cirrhosis and their influence on prognosis. Methods A total of 416 patients with liver cirrhosis who were hospitalized in a grade A tertiary hospital in Chongqing from September 2019 to June 2020 were enrolled in the study, and according to the presence or absence of CHE, they were divided into CHE group with 212 patients and non-CHE group with 204 patients. Clinical data and laboratory examination results were collected, and follow-up was performed for 6 months. The t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test, the continuous correction chi-square test, and the Mann-Whitney U test were used for comparison of categorical data between groups. Univariate and multivariate logistic regression analyses were used to analyze the risk factors for CHE. Results The incidence rate of CHE was 51%. The univariate analysis showed that age, course of disease, the medical history of hepatic encephalopathy (HE), infection, ascites, electrolyte disturbance, hepatorenal syndrome, Child-Pugh class, prothrombin time, total bilirubin, creatinine, platelet, prothrombin activity, albumin, and Model for End-stage Liver Disease (MELD) score were the influencing factors for CHE (all P < 0.05). The multivariate logistic regression analysis showed that the medical history of HE ( OR =10.848, 95% CI : 4.971-23.674, P < 0.05), transjugular intrahepatic portosystemic shunt (TIPS) ( OR =4.334, 95% CI : 1.203-15.621, P < 0.05), Child-Pugh class ( OR =4.968, 95% CI : 1.299-18.992, P < 0.05), and MELD score ( OR =1.253, 95% CI : 1.161-1.352, P < 0.05) were independent predictive factors for CHE ( P < 0.05). The follow-up study showed that CHE had an effect on the short-or medium-term readmission, HE, and death of patients (all P < 0.05). Conclusion CHE has a relatively high incidence rate and greatly affects the prognosis of patients with liver cirrhosis. The development of CHE should be taken seriously in patients with a past history of HE, a history of TIPS, Child-Pugh class C liver function, and a high MELD score, and identification, screening, and intervention should be performed as early as possible to improve the prognosis of patients with liver cirrhosis.
