OBJECTIVE:
Salt-processed Psoraleae Fructus (SPF) is widely used as a phytoestrogen-like agent in the treatment of osteoporosis. However, due to improper clinical use or misuse, resulting in liver damage. In this study, network pharmacology was employed to analyze the mechanism of cholestatic liver damage. An adeno-associated virus overexpressing SULT1E1 (rAAV8-SULT1E1) was constructed and the hepatotoxicity of SPF, psoralen, and isopsoralen was determined.
METHODS:
By utilizing three databases inclding TCMSP, TCMID, and BATMAN- TCM, the targets of the three databases were summarized, and a total of 45 psoralen compounds were included. Network pharmacology analysis was then performed. The adenoviral vectors were injected into the tail vein of C57BL6 mice to elucidate the role of SULT1E1 in SPF-induced cholestasis-mediated hepatotoxicity in vivo. SPF (10 g/kg), psoralen, and isopsoralen (50 mg/kg each) were intragastrically administered to mice for 30 d. B-ultrasound and samples were collected and examined for follow-up experiments.
RESULTS:
A total of 854 targets were predicted for 45 active components, with 151 cholestasis-mediated hepatotoxicity-related disease targets obtained for SPF. A total of 126 pathways were enriched based on KEGG pathway analysis, with the "estrogen signaling pathway" identified as one of the top 20 pathways. In terms of pathological hepatic changes, treated mice had visually swollen hepatocytes, dilated bile ducts, and elevated serum biochemical markers, which were more prominent in mice treated with isopsoralen than in those treated with other compounds. Notably, the overexpression of SULT1E1 could reverse liver damage in each treatment group. B-ultrasound was used to observe the size of the gallbladder in vivo. The size of the gallbladder was found to significantly increase on day 30 after treatment in the SPF-, psoralen-, and isopsoralen-treated groups, especially the SPF group. Compared with the expression levels in the negative control group (rAAV8-empty + con), the expression levels of FXR, Mrp2, Bsep, SULT1E1, SULT2A1, Ntcp, and Nrf2 decreased, whereas those of CYP7a1 and IL-6 increased in the SPF-, psoralen-, and isopsoralen-treated groups.
CONCLUSION
The overexpression of SULT1E1 could alleviate the decreased or increased expression of indicators, indicating that SULT1E1 is an important target gene for SPF-induced liver damage. The severity of liver damage was significantly lower in the rAAV8-SULT1E1 groups than in the rAAV8-empty groups.

Objective:To establish an environmental management strategy for the prevention of ventilator-associated pneumonia from the perspective of etiological characteristics and to verify its application effect.Methods:Based on a sampling survey, this study constructed preventive management strategies for ventilator-associated pneumonia by blocking pathogen characteristics from the perspective of both colonization and infection management in patients. From July 2021 to June 2023, a non-synchronous randomized controlled study was conducted, including a control group of 59 cases and an experimental group of 57 cases from ICU of Tianjin Teda Hospital, all of them were mechanically ventilated patients. The effectiveness of the strategy was confirmed.Results:In the control group, there were 35 males and 24 females, with an average age of (46.97 ± 18.84) years. In the experimental group, there were 39 males and 18 females, with an average age of (47.49 ± 13.85) years. During the study period, there were 9 cases of ventilator-associated pneumonia (VAP) in the control group and 2 cases in the experimental group, the difference between the two groups was statistically significant (exact odds ratio=0.031). The duration of mechanical ventilation in the experimental group (122.41 ± 18.36) h, which was shorter than that in the control group (187.62 ± 18.05) h, and the difference was statistically significant ( t=19.28, P<0.05). The length of ICU stay in the experimental group was (8.38 ± 0.79) d, in the control group was (10.99 ± 1.10) d, the difference between them was statistically significant ( t=14.66, P<0.05). On the 7th day, there were 7 cases of positive pathogenic bacteria in sputum culture in the experimental group, which was significantly different from the 29 cases in the control group ( χ2=16.73, P<0.05). Conclusions:The vector management strategy for preventing ventilator-associated pneumonia by blocking etiological characteristics can reduce the incidence of VAP, shorten the duration of mechanical ventilation and ICU stay, and reduce the pathogen load in the sputum of mechanically ventilated patients on the 7th day.

BACKGROUND:Mangiferin is a biphenylpyridone compound extracted from mango leaves,bark and roots.Previous studies have shown that mangiferin can exert anti-systemic inflammatory effects through the activation of transcription factors such as NF-κB and JAK/STAT. OBJECTIVE:To investigate the effects and mechanisms of mangiferin on proliferation,migration and inflammatory factor release of rheumatoid arthritis fibroblast-like synovial cells(RA-FLS). METHODS:RA-FLS were divided into blank group,R848(TLR7/8 agonists)stimulated group,mangiferin low-,medium-,high-dose groups(2,4 and 8 μg/mL)and positive control group(Cu-CPT8,TLR8 pathway inhibitor).The cytotoxic effect of different mass concentrations of mangiferin was detected using cell counting kit-8 method and the final cellular dosing mass concentration was screened.The proliferation ability of RA-FLS was detected by cell clone formation assay,the migration ability of RA-FLS was detected by scratch assay and Transwell migration assay,and the expression of interleukin 1β,interleukin 6 and tumor necrosis factor α mRNA in RA-FLS was detected by qRT-PCR. RESULTS AND CONCLUSION:Compared with the blank group,the viability of RA-FLS was inhibited after treatment with mangiferin at 2-10 μg/mL,but there was no significant difference among groups(P>0.05),indicating that the toxic effect on RA-FLS was minimal.Compared with the R848-stimulated group,mangiferin decreased the number of cell clones,the scratch healing rate and the number of migrating cells in all dosing groups(P<0.01);and the expression of interleukin 1β,interleukin 6 and tumor necrosis factor α mRNA was also reduced in the mangostin medium-and high-dose groups(P<0.01).Compared with the R848-stimulated group,the number of cell clones,the scratch healing rate and the number of migrating cells as well as the expression levels of interleukin 6 and tumor necrosis factor α mRNA were significantly reduced in the positive control group(P<0.05,P<0.01).But there was no significant difference in the expression level of interleukin 1β.To conclude,mangiferin may exert its anti-rheumatoid arthritis effects through the TLR7/8 signaling pathway by inhibiting RA-FLS proliferation,migration,and inflammatory factor release.

Objective:To analyze and explore the clinical characteristics and risk factors related to nosocomial mortality in patients with liver cirrhosis combined with atrial arrhythmia.Methods:252 hospitalized patients with liver cirrhosis combined with atrial arrhythmia from January 2014 to December 2021 were enrolled, and their clinical characteristics were analyzed. The above-mentioned patients were divided into groups according to their nosocomial mortality rate. Among them, 45 nosocomial mortality cases were classified as the mortality group, and 207 survival cases were classified as the survival group. The differences in clinical data and laboratory data between the two groups were compared. The risk factors for nosocomial mortality in patients with liver cirrhosis combined with atrial arrhythmia were analyzed. The t-test, or rank-sum test, was used to compare measurement data. The chi-square test, or Fisher's exact probability method, was used to compare enumeration data. Multivariate analysis was performed by the logistic regression method.Results:Among the 252 cases, the male-to-female ratio was the same (male/female ratio: 126/126). The age range was 26 to 89 (66.77±10.46) years. Han ethnicity accounted for 79.5%. The main type of atrial arrhythmia was atrial fibrillation ( P ?0.001). The main cause of liver cirrhosis was post-hepatitis B cirrhosis (56.3%). There were 57/72/123 cases of CTP grade A/B/C. The CTP and Model for End-Stage Liver Disease (MELD) scores were 10.30±1.77 and 18.0(11.0, 29.0), respectively. The nosocomial mortality rate was 17.9% (45/252). The overall incidence rate of complications in all patients was 89.28%, with complications occurring in the following order: 71.4% ascites, 71.0% hypersplenism, 64.7% spontaneous peritonitis, 64.3% esophageal gastric varices, 32.5% hepatorenal syndrome, 32.1% hepatic encephalopathy, and 26.2% esophageal gastric variceal bleeding. The incidence rate of new-onset atrial fibrillation in the nosocomial mortality group was 73.3%, which was much higher than the 44.0% rate in the survival group ( P ?0.05). Multivariate logistic regression analysis showed that new-onset atrial fibrillation ( OR=2.707, 95% CI 1.119?~?6.549), esophageal-gastric varices ( OR=3.287, 95% CI 1.189?~?9.085), serum potassium ( OR=3.820, 95% CI 1.532?~?9.526), and MELD score ( OR=1.108, 95% CI 1.061~1.157) were independent risk factors for nosocomial mortality in patients with liver cirrhosis combined with atrial arrhythmia. Conclusion:Patients with cirrhosis combined with atrial arrhythmias have more severe liver function damage and are more likely to develop complications such as ascites, hypersplenism, and hepatorenal syndrome. New-onset atrial fibrillation, esophageal-gastric varices, hyperkalemia, and a high MELD score are risk factors for nosocomial mortality in patients with liver cirrhosis combined with atrial arrhythmia, so more attention should be paid to corresponding patients for timely symptomatic treatment.

Objective:To investigate the effects of Sennoside A (SA) on the proliferation, migration, invasion, glycolysis and other malignant biological behaviors of gallbladder carcinoma cells, and to analyze the related mechanisms.Methods:Human gallbladder carcinoma cell lines, NOZ and SGC-996, were cultured in vitro and divided into control group, SA low dose group (L-SA, 25 μmol/L), SA medium dose group (M-SA, 50 μmol/L) and SA high dose group (H-SA, 100 μmol/L), and H-SA+ phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling pathway activator 740Y-P group, respectively. The proliferation, migration, invasion, apoptosis and glycolysis of gallbladder cancer cells in each group were detected by cell counting assay, Transwell, flow cytometry and glycolysis kit. The protein levels of PI3K, p-PI3K, AKT and p-AKT were detected by Western blot assay. NOZ cells were used to construct tumor model of nude mice, and the mice were divided into saline treatment group and 10 mg/kg SA treatment group. The tumor formation ability of the two groups of mice was compared, and the expression level of Ki-67 in tumor of the two groups was detected by immunohistochemical assay.Results:Compared with control group, the proliferation, migration, invasion, glycolysis ability, the expression levels of p-PI3K and p-AKT were significantly decreased in SA treatment groups, while the apoptosis level was significantly up-regulated, all differences were statistically significant ( P<0.05). Compared with H-SA group, the proliferation, migration, invasion and glycolysis of H-SA+ 740Y-P group cells were up-regulated, while the apoptosis level was significantly decreased, all differences were statistically significant ( P<0.05). In vivo tumorigenesis experiments showed that, compared with the control group, the tumor volume of the SA-treated mice was reduced at day 28 [(1 051.32±130.29) mm 3 vs (575.07±170.54) mm 3, P=0.0003), the tumor weight was reduced [(1.04±0.24) g vs (0.58±0.13) g, P=0.0019], and the average optical density of Ki-67 expression was reduced [(77.00±7.00) vs (33.33±7.51), P=0.0018]. Conclusion:SA can inhibit the proliferation, migration, invasion and glycolysis of gallbladder carcinoma cells by regulating PI3K/AKT pathway.
