OBJECTIVE To investigate the intervention effect and potential mechanism of breviscapine on hepatic fibrosis (HF) in rats based on the transforming growth factor-β(1 TGF-β1)/Smad2/extracellular signal-regulated protein kinase 1(ERK1) and Kelch-like epichlorohydrin-associated protein 1(Keap1)/nuclear factor-erythroid 2-related factor 2(Nrf2)/heme oxygenase-1(HO-1) pathways. METHODS Totally 60 rats were randomly divided into normal control group, model group, breviscapine low-dose, medium-dose and high-dose groups (5.4, 10.8, 21.6 mg/kg), and colchicine group (positive control, 0.45 mg/kg), with 10 rats in each group, half male and half female. Except for the normal control group, HF model of the other groups was induced by carbon tetrachloride. Subsequently, each drug group was given corresponding medicine by gavage once a day for 28 days. The liver appearance of rats in each group was observed and their liver coefficients were calculated. The levels of alanineaminotransferase (ALT) and aspartate aminotransferase (AST)in serum, those of ALT, AST, superoxide dismutase (SOD),malondialdehyde (MDA) and glutathione peroxidase (GSH- Px) in liver tissue were detected. The liver tissue inflammatory and fibrotic changes were observed. The protein and mRNA expressions of TGF-β1, Smad2, ERK1, Nrf2, Keap1 and HO-in liver tissue were detected. RESULTS Compared with the normal control group, the model group showed large areas of white nodular lesions in the liver, obvious inflammatory cell infiltration and collagen fiber deposition. The body weight, the levels of SOD and GSH-Px in liver tissue, the protein and mRNA expressions of Nrf2 and HO-1 were significantly lowered in the model group (P<0.05); the liver coefficient, the percentage of Masson staining positive area, ALT and AST levels of serum and liver tissue, MDA level of liver tissue, the protein and mRNA expressions of TGF-β1, Smad2, ERK1 and Keap1 were significantly increased (P<0.05). Compared with the model group, the liver lesions of rats in each drug group were improved, and the above quantitative indexes were generally reversed (P<0.05). CONCLUSIONS Breviscapine has a good intervention effect on HF rats, which may be related to inhibiting TGF-β1/Smad2/ERK1 pathway for anti-fibrosis and regulating Keap1/Nrf2/HO-1 pathway to inhibit oxidative stress.

OBJECTIVE To comprehensively evaluate the three oral Janus kinase inhibitors (JAKi) such as upadacitinib, abrocitinib and baricitinib in the treatment of atopic dermatitis. METHODS The six dimensions of safety, efficacy, economy, appropriateness, accessibility and innovativeness were used for evaluation. Meta-analysis was conducted to evaluate the safety and efficacy of three oral JAKi; pharmacoeconomic studies were searched, and the treatment costs were calculated to evaluate the economy of each JAKi. Appropriateness was described based on literature review and drug labels. Accessibility of three oral JAKi was assessed by using a questionnaire survey. The innovation of JAKi was elucidated from the perspective of its mechanism of action. RESULTS In terms of safety, the incidence of upper respiratory tract infection (OR=1.47, 95%CI of 1.04-2.08, P=0.03) and nasopharyngitis (OR=1.44, 95%CI of 1.06-1.95, P=0.02) in the upadacitinib 30 mg group was significantly higher than that in the placebo group; the incidence of nasopharyngitis in baricitinib 4 mg group was significantly higher than that in the placebo group (OR=2.24, 95%CI of 1.39-3.61, P=0.000 8) and baricitinib 2 mg group (OR=0.48, 95%CI of 0.31-0.74,P=0.001). In terms of efficacy, regardless of the dosage, all three JAKi groups were superior to the placebo group, and the high-dose groups of upadacitinib and abrocitinib were superior to the low-dose groups (P<0.000 1). In terms of economy, the annual treatment cost of baricitinib was the lowest (13 870.0 yuan), but it has not been approved for atopic dermatitis indication in China; next was upadacitinib (27 192.5 yuan). In terms of appropriateness, the overall appropriateness of the three JAKis was good, but none of them was suitable for patients with severe liver injury. In terms of accessibility, baricitinib had the highest availability rate (59.4%), but the affordability of upadacitinib was relatively good under China’s medical insurance system. In terms of innovation, among the three types of JAKi, upadacitinib and abrocitinib had better innovation. CONCLUSIONS Three oral JAKi treatments for atopic dermatitis have controllable safety and good efficacy. Considering the issue of medical insurance reimbursement, it is recommended that Chinese patients use upadacitinib.

ObjectiveTo reveal the molecular mechanism of Angong Niuhuangwan(AGNH) in improving traumatic brain injury(TBI) based on single cell sequencing. MethodSeventy-five male SD rats were randomly divided into the sham group, model group, piracetam group(3.6 g·kg-1), AGNH low- and high-dose groups(0.09, 0.27 g·kg-1), with 15 rats in each group. In addition to the sham group, the other 4 groups used the modified Feeney free-fall impact method to prepare TBI model, and the drugs were administered by gavage immediately after modeling, 24 hours later, the modified neurological deficit score(mNSS) was performed, and brain tissue was isolated to determine the degree of cerebral edema. Hematoxylin-eosin(HE) staining was used to observe the injury degree in the cortex, CA1 region and CA3 region of brain tissue. The expression levels of cyclooxygenase-2(COX-2), interferon regulatory factor 1(IRF1), Janus kinase 2(JAK2) and suppressor of cytokine signaling 3(SOCS3) were observed by immunofluorescence(IF) staining. The levels of interleukin(IL)-6, IL-18, IL-1β, IL-17A, tumor necrosis factor-α(TNF-α), Caspase-1 and nucleotide binding oligomerization domain(NOD)-like receptor heat protein domain associated protein 3(NLRP3) inflammasome were determined by enzyme-linked immunosorbent assay(ELISA). The regulation of AGNH on each cell population was analyzed by single cell sequencing, and differentially expressed genes were analyzed by Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG), which led to construct microglia differentially expressed gene network to search for the key targets, and validated by ELISA and IF. ResultCompared with the sham group, the mNSS and brain water content were significantly increased in the model group(P<0.01). Compared with the model group, mNSS and brain water content in the low and high dose AGNH groups were decreased(P<0.05,P<0.01). HE staining results showed that compared with the sham group, the cells in the cerebral cortex and hippocampus of rats in the model group were seriously lost, and the cells were arranged loosely(P<0.01). Compared with the model group, AGNH could significantly increase the density of neurons in the CA1 and CA3 regions of the cerebral cortex and hippocampus, making the arrangement more compact, as well as improved cell morphology(P<0.05,P<0.01). ELISA and IF staining showed that AGNH could reduce the levels of Caspase-1, IL-17A, TNF-α, NLRP3 and COX-2 in brain tissue of TBI rats(P<0.05, P<0.01). A total of 13 cell subsets were identified by single cell sequencing, among which microglia played an important role in neuroimmunity. The results of GO enrichment analysis of differentially expressed genes in microglia showed that AGNH improved TBI in response to inflammation and TNF-α. KEGG enriched IL-17 signaling pathway, TNF signaling pathway, Toll-like receptor signaling pathway, etc. The results of network analysis showed that the key targets of AGNH in regulating TBI might be IL-6, IL-1β, JAK2, SOCS3, IRF1. IF and ELISA verification results showed that compared with the sham group, SOCS3 expression in microglia was decreased in the model group, and the expressions of IL-6, IL-1β, JAK2 and IRF1 were increased(P<0.01). Compared with the model group, AGNH could increase the expression of SOCS3, decrease the expression of IL-6, IL-1β, JAK2, IRF1 (P<0.05, P<0.01). ConclusionAGNH can reduce the degree of brain edema and brain injury, decrease the expression of inflammatory factors, and inhibit the expression of NLRP3 and its downstream Caspase-1 in TBI rats, which may act on the targets of IL-6, IL-1β, JAK2, IRF1 and SOCS3 in microglia.

Objective To explore the correlation of CPNE3 expression with long-term prognosis of patients with gastric cancer(GC)and the possible mechanism.Methods We retrospectively collected the data of 104 GC patients undergoing radical surgery in our hospital from February,2013 to October,2017.TCGA database and immunohistochemistry were used to analyze CPNE3 expression level in GC tissues and its effects on tumor progression and long-term prognosis of the patients.GO analysis was performed to predict the biological role of CPNE3 in GC.We also conducted cell experiments with MGC803 cells and observed the effects of CPNE3 knockdown,CPNE3 overexpression and LY294002(a PI3K/AKT inhibitor)treatment on cell apoptosis and cellular expressions of apoptotic proteins using flow cytometry and Western blotting.Results TCGA analysis and immunohistochemistry both showed high expressions of CPNE3 in GC(P<0.05).The patients with high CPNE3 expressions had a reduced 5-year survival(P<0.01),and a high CPNE3 expression,CEA level≥5 μg/L,CA19-9 level≥37 kU/L,T3-T4 stage,and N2-N3 stage were all independent risk factors for a lowered 5-year survival rate after surgery.The sensitivity and specificity of CPNE3 for predicting 5-year mortality was 79.59%and 74.55%,respectively(P<0.05).GO analysis predicted that CPNE3 negatively regulated GC cell apoptosis.In MGC803 cells,CPNE3 knockdown significantly increased cell apoptosis,enhanced Bax and Cleaved Caspase-3 expressions and decreased Bcl-2 expression,while CPNE3 overexpression produced the opposite results(P<0.05).The cellular expressions of p-PI3K and p-AKT were significantly decreased following CPNE3 knockdown and increased following CPNE3 overexpression(P<0.05).Treatment with LY294002 obviously attenuated the inhibitory effect of CPNE3 overexpression on apoptosis of MGC803 cells(P<0.05).Conclusion CPNE3 is highly expressed in GC tissues and affects the long-term prognosis of the patients possibly by inhibiting GC cell apoptosis through activation of PI3K/AKT signaling.

Objective To analyze the expression level of ATP5A1 in gastric carcinoma and its influence on the prognosis of the patients and glucose metabolism in the tumor cells.Methods We retrospectively analyzed the data of 115 patients undergoing radical resection of gastric carcinoma in our hospital from February,2013 to November,2016.ATP5A1 expression in the surgical specimens were detected using immunohistochemistry,and the long-term prognosis of the patients with high(n=58)and low ATP5A1 expression(n=57)were analyzed.In gastric carcinoma MGC803 cells,the effects of lentivirus-mediated ATP5A1 knockdown or overexpression on glucose metabolism were investigated.We also observed the growth and glucose metabolism of xenografts derived from MGC803 cells with ATP5A1 knockdown or overexpression in nude mice.Results ATP5A1 was significantly overexpressed in gastric carcinoma tissues in close correlation with blood CEA and CA19-9 levels,pathological grade,T stage and N stage(P<0.05).ATP5A1 overexpression was an independent risk factor for a significantly lowered 5-year survival rate of patients with gastric carcinoma(P<0.05).ROC curve analysis demonstrated the predictive value of high ATP5A1 expression for the patients'prognosis(P<0.001).In MGC803 cells,ATP5A1 overexpression significantly up-regulated cellular glucose uptake and lactate production and increased the protein levels of HK2,PFK1,and LDHA(P<0.05),while ATP5A1 knockdown produced the opposite changes(P<0.05).In the tumor-bearing mice,overexpression of ATP5A1 increased glucose metabolism of the tumor cells and promoted tumor growth(P<0.05).Overexpression of ATP5A1 promoted the expressions of p-JNK and p-JUN in MGC803 cells(P<0.05),and the JNK inhibitor SP600125 significantly inhibited the enhancement of cellular glucose metabolism induced by ATP5A1 overexpression(P<0.05).Conclusion High ATP5A1 expression in gastric cancer is associated a poor long-term prognosis of the patients,and its effect is mediated at least partly by promoting glucose metabolism of the cells through the JNK/JUN pathway.

Objective:To retrospectively analyze the clinical characteristics and prognosis of 85 newly diagnosed patients with follicular lymphoma (FL), as well as the prognostic value of comprehensive geriatric assessment (CGA) in patients with FL aged ≥ 60 years old.Methods:The clinical data and prognosis of 85 newly diagnosed FL patients admitted from August 2011 to June 2022 were collected. The clinical features, laboratory indicators, therapeutic efficacy, survival and prognostic factors of patients were statistically analyzed, and the prognosis of patients was stratified using various geriatric assessment tools.Results:① The patients with FL were mostly middle-aged and older, with a median age of 59 (20-87) years, including 41 patients (48.2%) aged ≥60 years. The ratio of male to female was 1∶1.36. Overall, 77.6% of the patients were diagnosed with Ann Arbor stage Ⅲ-Ⅳ, and 17 cases (20.0%) were accompanied by B symptoms. Bone marrow involvement was the most common (34.1%). ②Overall, 71 patients received immunochemotherapy. The overall response rate was 86.6%, and the complete recovery rate was 47.1% of 68 evaluated patients. Disease progression or relapse in the first 2 years was observed in 23.9% of the patient. Overall, 14.1% of the patients died during follow-up. ③Of the 56 patients receiving R-CHOP-like therapies, the 3-year and 5-year progression-free survival (PFS) rates were 85.2% and 72.8%, respectively, and the 3-year and 5-year overall survival (OS) rates were 95.9% and 88.8%, respectively. The univariate analysis showed that age ≥60 years old ( HR=3.430, 95% CI 1.256-9.371, P=0.016), B symptoms ( HR=5.030, 95% CI 1.903-13.294, P=0.016), Prognostic Nutritional Index (PNI) <45.25 ( HR=3.478, 95% CI 1.299-9.310, P=0.013), Follicular Lymphoma International Prognostic Index (FLIPI) high-risk ( HR=2.918, 95% CI 1.074-7.928, P=0.036), and PRIMA-prognostic index (PRIMA-PI) high-risk ( HR=2.745, 95% CI 1.057-7.129, P=0.038) significantly predicted PFS. Moreover, age ≥60 years old and B symptoms were independent risk factors for PFS. Progression of disease within 24 months (POD24) significantly predicted OS in the univariate analysis. Conclusions:FL is more common among middle-aged and older women. Age, B symptoms, PNI score, FLIPI high-risk, PRIMA-PI high-risk, and POD24 influenced PFS and OS. The CGA can be used for treatment selection and risk prognostication in older patients with FL.

Objective:Exploring the efficacy and safety of bridging blinatumomab (BiTE) in combination with chimeric antigen receptor T (CAR-T) cell therapy for the treatment of adult patients with acute B-cell lymphoblastic leukemia (B-ALL) .Methods:Clinical data from 36 adult B-ALL patients treated at the First Affiliated Hospital of Suzhou University from August 2018 to May 2023 were retrospectively analyzed. A total of 36 cases were included: 18 men and 18 women. The median age was 43.5 years (21-72 years). Moreover, 21 cases of Philadelphia chromosome-positive acute lymphoblastic leukemia were reported, and 16 of these cases were relapsed or refractory. Eighteen patients underwent blinatumomab bridging followed by CAR-T cell therapy, and 18 patients received CAR-T cell therapy. This study analyzed the efficacy and safety of treatment in two groups of patients.Results:In the BiTE bridge-to-CAR-T group, 16 patients achieved complete remission (CR) after BiTE immunotherapy, with a CR rate of 88.9%. One month after bridging CAR-T therapy, bone marrow examination showed a CR rate of 100.0%, and the minimal residual disease (MRD) negativity rate was higher than the nonbridging therapy group (94.4% vs. 61.1%, Fisher, P=0.041). The incidence of cytokine release syndrome and other adverse reactions in the BiTE bridge-to-CAR-T group was lower than that in the nonbridging therapy group (11.1% vs. 50.0%, Fisher, P=0.027). The follow-up reveals that 13 patients continued to maintain MRD negativity, and five patients experienced relapse 8.40 months (2.57-10.20 months) after treatment. Two of five patients with relapse achieved CR after receiving the second CAR-T cell therapy. In the nonbridging therapy group, 10 patients maintained continuous MRD negativity, 7 experienced relapse, and 6 died. The 1 year overall survival rate in the BiTE bridge-to-CAR-T group was higher than that in the nonbridging therapy group, with a statistically significant difference at the 0.1 level (88.9%±10.5% vs. 66.7%±10.9%, P=0.091) . Conclusion:BiTE bridging CAR-T cell therapy demonstrates excellent efficacy in adult B-ALL treatment, with a low recent recurrence rate and ongoing assessment of long-term efficacy during follow-up.
