Qinggan Huoxue Recipe Protects against Experimental Alcoholic Liver Fibrosis through CXCL16 Inhibition. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2023; 2023:5642713. [PMID: 36636609 PMCID: PMC9831707 DOI: 10.1155/2023/5642713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 11/23/2022] [Accepted: 12/06/2022] [Indexed: 01/05/2023]
Abstract
Background Qinggan Huoxue recipe (QGHXR), a traditional Chinese medicinal formula, has a protective effect against liver fibrosis. However, the underlying mechanisms remain unclear. Objective This study investigated the antifibrotic role of QGHXR and its underlying mechanisms. Methods The composition of QGHXR was determined using ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Female C57BL/6J mice were fed either a Lieber-DeCarli liquid diet or pair-fed control diet and intraperitoneally injected with CCl4 for 8 weeks (n = 8). In week 5, the mice were administered 100, 200, and 400 mg/kg QGHXR via oral gavage daily for 4 weeks. Results UPLC-MS result showed that QGHXR contained 45 compounds including salvianolic acid A, scutellarin, baicalin, rutin, and chai saponin D. QGHXR alleviated pathological alterations in the liver. The alanine aminotransferase (ALT) level was reduced to 44.88 ± 4.39 U/L, aspartate aminotransferase (AST) to 76.25 ± 4.17 U/L, alkaline phosphatase (ALP) to 60.75 ± 5.41 U/L, and acetaldehyde to 38.54 ± 1.01 U/L compared with that of the control group (ALT 72.38 ± 5.19 U/L, AST 119.63 ± 9.82 U/L, and ALP 98.63 ± 6.71 U/L and acetaldehyde 64.86 ± 4.70 U/L). QGHXR inhibited lipid overproduction and fibrotic gene expression. The serum concentration of chemokine C-X-C ligand 16 (CXCL16) was reduced to 62.83 ± 6.80 pg/ml compared with that of the control group (130.91 ± 13.72 pg/mL). QGHXR downregulated CXCL16 mRNA and protein expressions. Pharmacological CXCL16 treatment reversed the QGHXR-induced protective effects in ethanol plus CCl4 fed mice. QGHXR reduced CXCL16 levels (91.97 ± 5.86 pg/ml) in LPS-stimulated RAW264.7 cells compared with that of the control group (148.68 ± 8.62 pg/ml) and inhibited toll-like receptor 4 and nuclear factor-kappa B phosphorylation. Conclusions This study demonstrated that QGHXR mitigates experimental alcoholic liver fibrosis by CXCL16 inhibition, and may be considered a potential therapeutic agent for treating liver fibrosis.

Abstract
Background Considering the narrow immune response spectrum of a single epitope, and the nanoparticles (NPs) as a novel adjuvant can achieve efficient delivery of antigenic peptides safely, a nano-system (denoted as DSPE-PEG-Man@EM-NPs) based on cathepsin B-responsive antigenic peptides was designed and synthesized. Methods Highly affinitive antigenic peptides were delivered by self-assembled NPs, and targeted erythrocyte membranes acted as a peptide carrier to improve antigenic peptides presentation and to strengthen cytotoxic T-cells reaction. Cathepsin B coupling could release antigenic peptides rapidly in dendritic cells. Results Evaluations showed that DSPE-PEG-Man@EM-NPs had obvious inhibitory effects towards both MCF-7 and MDA-MB-231 human breast cancer cell lines. Conclusion Overall, this strategy provides a novel strategy for boosting cytotoxic T lymphocytes response, thereby expanding the adaptation range of tumor antigenic peptides and improving the therapeutic effect of tumor immunotherapy with nanomedicine.

Abstract
The effects of infection with Toxoplasma gondii vary from asymptomatic to the development of alterations in various organs (including the liver and kidneys) which may be irreversible, and lead to the death of the host. Whereas homeopathy is an alternative and effective method for treating various diseases, including those caused by protozoa, we questioned the effect of using Lycopodium clavatum in mice infected with T. gondii. One hundred male Swiss mice, 60 days old, were divided into four groups (n = 25/group): NIC (uninfected and untreated control), IC (infected and treated with un-dynamized 7% alcohol solution [vehicle]), G48 (infected and treated 48 h before infection and treated three more times; at 2, 4, and 6 days post-infection (dpi) with L. clavatum 200dH), and G72 (infected and treated for 3 consecutive days before infection with L. clavatum 200dH). In this study, physiological, histopathological, and immunological parameters were evaluated. The L. clavatum 200dH intensified renal damage in mice infected with T. gondii from 7 dpi, causing severe and progressive alterations during this period, such as various degrees of inflammation, edema, atrophy, and tubular cystic dilation, degenerated tubules with intra-cytoplasmic vacuoles and coalescing spots, severe vascular lesions, glomerulonephritis, and peri-glomerular congestion. In the G72 animals, which received L. clavatum 200dH, more severe cortex damage was observed (91.66-96.66%) as compared to the IC group (55-80%) and more renal corpuscle, and renal tubule injury was observed (80 ± 5 to 96.7% ± 2.89 of the total area) during all periods, as compared to the IC group (p < 0.05). Both groups presented high liver enzyme levels, and the highest values for AST were observable at 60 dpi. We observed significant increases of type I and III collagen, as well as high levels of TGF-β1 in both organs of the treated animals, the main factor involved in fibrosis in areas damaged by the process. L. clavatum 200dH intensifies kidney and liver alterations in mice infected with T. gondii. Our results reinforce caution when indicating administration schemes and dosages for ultra-diluted drugs.

Abstract
Chronic obstructive pulmonary disease (COPD) is partly characterized as epithelial-mesenchymal transition (EMT)-related airflow limitation. Extracellular vesicles (EVs) play crucial roles in the crosstalk between cells, affecting many diseases including COPD. Up to now, the roles of EVs in COPD are still debated. As we found in this investigation, COPD patients have higher miR-21 level in total serum EVs. EMT occurs in lungs of COPD mice. Furthermore, bronchial epithelial cells (BEAS-2B) could generate EVs with less miR-21 when treated with cigarette smoke extract (CSE), impacting less on the M2-directed macrophage polarization than the control-EVs (PBS-treated) according to EVs miR-21 level. Furthermore, the EMT processes in BEAS-2B cells were enhanced with the M2 macrophages proportion when co-cultured. Collectively, these results demonstrate that CSE-treated BEAS-2B cells could alleviate M2 macrophages polarization by modulated EVs, and eventually relieve the EMT process of BEAS-2B cells themselves under COPD pathogenesis, revealing a novel compensatory role of them in COPD.

Abstract
Background: ZW10 interactor was recently reported to correlate with human cancers. However, the
prognostic value of ZW10 interactor in hepatocellular carcinoma was not reported. Methods: The expression level of ZW10 interactor was evaluated by Western blot and
immunohistochemistry using tissue microarray. In the present study, we used 5 pairs of
hepatocellular carcinoma and peritumoral frozen tissues for Western blot, and 70 paired
paraffin-embedded hepatocellular carcinoma and peritumoral tissues as expression pattern
cohort (cohort 1), and 280 paraffin-embedded hepatocellular carcinoma tissues were used
as prognostic cohort (cohort 2). The integral optic density representing the expression
level of ZW10 interactor in each tissue sample, was calculated using Image-Pro Plus. The
integral optic density was added to the X-tile software for calculating the
outcome-based cut point. Kaplan-Meier and Cox regression were used to evaluate the
prognostic values. Results: The expression level ZW10 interactor was decreased in hepatocellular carcinoma tissues
in 85.7% (60/70) of the cases compared to the corresponding peritumoral tissues
evaluated by immunohistochemistry. Similar result was obtained by Western blot analysis
using frozen tissue. Expression of ZW10 interactor was closely correlated with age
(P = .0001) and liver cirrhosis in cohort 1 and tumor node metastasis
(P = .018), tumor size (P = .005), and vascular
invasion (P = .022) in cohort 2 based on χ2 analyses.
Survival analyses indicated that patients with hepatocellular carcinoma having low ZW10
interactor expression had a shorter overall survival time and time to recurrence
compared to cases with high ZW10 interactor expression in the prognostic cohort
(P < .0001 for both overall survival and time to recurrence ).
Univariate and multivariate Cox analyses indicated that ZW10 interactor was an
independent prognostic factor for overall survival (P = .033). Conclusions: The present study clearly showed that ZW10 interactor was frequently decreased in
hepatocellular carcinoma compared to nontumoral liver tissues, and ZW10 interactor could
serve as a potential prognostic marker in patients with hepatocellular carcinoma after
surgery.

Abstract
The experimental model of combined allergic rhinitis and asthma syndrome (CARAS) has shown that CpG oligodeoxynucleotides (CpG-ODNs) are potential inhibitors of type 2 helper cell-driven inflammatory responses. Currently available CpG-ODNs modestly inhibit allergic responses in CARAS, while a combination strategy for upper airway treatment by co-administration of CpG-ODNs and glucocorticoids may show good efficacy. This study aimed to assess the therapeutic effects of CpG-ODNs combined with budesonide (BUD) on upper and lower-airway inflammation and remodeling in mice with CARAS induced by chronic exposure to ovalbumin (OVA), exploring the possible underlying molecular mechanisms. A BALB/c mouse model of chronic CARAS was established by systemic sensitization and repeated challenge with OVA. Treatment with CpG-ODNs or BUD by intranasal administration was started 1 h after OVA challenge. Then, nasal mucosa and lung tissues were fixed and stained for pathologic analysis. The resulting immunologic variables and TSLP-DC-OX40L axis parameters were evaluated. Both CpG-ODNs and BUD intranasal administration are effective on reducing Th2-type airway inflammation and tissue remodeling. Co-administration of CpG-ODNs and BUD was more effective than each monotherapy in attenuating upper and lower-airway inflammation as well as airway remodeling in chronic CARAS. Notably, combination of CpG-ODNs with BUD modulated the TSLP-DC-OX40L axis, as demonstrated by decreased TSLP production in the nose and lung, alongside decreased TSLPR and OX40L in DC. Intranasal co-administration of CpG-ODNs and BUD synergistically alleviates airway inflammation and tissue remodeling in experimental chronic CARAS, through shared cellular pathways, as a potent antagonist of the TSLP-DC-OX40L axis.

Abstract
BACKGROUND Soluble TGF-β1 type II receptor (sTβRII) via TGF-β1 inhibition could inhibit hepatic fibrosis, but over-dosage triggers autoimmune responses. AIM To test whether the use of a TGF-β1-responsive collagen I promoter COL1A1, via generating a feedback loop to TGF-β1 level, could offer accurate control on sTβRII expression. METHODS Recombinant adenoviruses with COL1A1 (Ad-COL-sTβRII/Luc) or CMV promoter (Ad-CMV-sTβRII/Luc) were constructed and characterized. Inhibition of TGF-β activity was determined both in vitro and in vivo. Total and bioactive TGF-β, hepatic fibrosis scale, α-SMA, collagen levels, and liver function were determined. RESULTS COL1A1, but not CMV, responded to TGF-β1 in vitro. Both in vitro and in vivo, Ad-COL-sTβRII could significantly, but not completely inhibit TGF-β1 activity while Ad-CMV-sTβRII almost completely inhibited TGF-β1 activity. As evidenced by fibrosis scale, α-SMA, and collagen levels in liver tissue, Ad-COL-sTβRII and Ad-CMV-sTβRII had comparable efficacies in treating hepatic fibrosis. Ad-COL-sTβRII was better than Ad-CMV-sTβRII in liver function restore. Ad-CMV-sTβRII, but not Ad-COL-sTβRII, induced high level of anti-dsDNA and anti-Sm antibodies in rats. CONCLUSIONS COL1A1 can precisely control sTβRII expression to inhibit excessive bioactive TGF-β level and thus inhibit hepatic fibrosis but without inducing autoimmune responses.

Abstract
Background Understanding the biological features and developmental progress of cervical cancer is crucial for disease prevention. This study aimed to determine the nanomechanical signatures of cervical samples, ranging from cervicitis to cervical carcinomas, and to investigate the underlying mechanisms. Material/Methods Forty-five cervical biopsies at various pathological stages were subjected to atomic force microscopy (AFM) measurements. Cdc42 and collagen I were quantified using immunohistochemical staining to investigate their relationship with nanomechanical properties of cervical cancers and premalignant lesions. Results We found that the lower elasticity peaks (LEPs) in the high-grade squamous intraepithelial lesion (HSIL) group (21.24±3.83 kPa) and higher elasticity peaks (HEPs) in the cancer group (81.23±8.82 kPa) were upshifted compared with the control group (LEP at 8.51±0.18 kPa and HEP at 44.07±3.54 kPa). Furthermore, compared with the control [29.51±13.61 for cell division cycle 42 (Cdc42) expression and 28.61±17.65 for collagen I expression], immunohistochemical staining verified a significant increase of Cdc42 in the HSIL group (50.57±23.85) and collagen I (56.09±25.70) in the cancer group. In addition, using the Pearson correlation coefficient, Cdc42 expression tended to be positively correlated with LEP locations (r=0.63, P=0.012), while collagen I expression displayed a strong and positive correlation with HEP positions (r=0.88, P<0.001). Conclusions The nanomechanical properties of HSIL and cancer biopsies show unique features compared with controls, and these alterations are probably due to changes in cytoskeleton and extracellular matrix contents.

Abstract
Occurrence of postoperative cognitive dysfunction (POCD) is age-dependent and heterogenous. Factors deciding the occurrence of POCD in patients of the same age undergone same surgeries remain unclear. Here we investigated the effects of pre-existing weakness on the occurrence of POCD in mice of the same age. Pre-existing weakness of mice was induced by intraperitoneal injection of lipopolysaccharide (8mg/kg) and was evaluated by physical frailty index (by open field test), neuroinflammation level (by Iba1 immunostaining and inflammatory factors TNF-α and IL-1β), and neuronal activity (by p-CREB immunostaining). POCD was induced by partial hepatolobectomy and was evaluated by puzzle box test and Morris water maze test. The brains were collected to detect the levels of neuroinflammation, synaptophysin and NMDA receptor subunits NR2A, NR2B and NR1 (by western blot), and oxidative stress (by Dihydroethidium). Compared to the normal adult mice of the same age, LPS pretreated mice had increased physical frailty index, higher levels of neuroinflammation, and lower neuronal activity. Partial hepatolobectomy induced obvious impairments in executive function, learning and memory in LPS pretreated mice after surgery, but not in normal mice of the same age. Partial hepatolobectomy also induced heightened neuroinflammation, obvious loss of NMDA receptor subunits, strong oxidative stress in LPS pretreated mice on the 1st and 3rd postoperative day. However, the POCD-associated pathological changes didn’t occur in normal mice of the same age after surgery. These results suggest that pre-existing weakness is critical for the occurrence of POCD in mice of the same age.
