This study developed ferritin-based nanoparticles carrying the African swine fever virus (ASFV) p30 protein and evaluated their immunogenicity, aiming to provide an experimental basis for the research on nanoparticle vaccines against ASFV. Initially, the gene sequences encoding the p30 protein and SpyTag were fused and inserted into the pCold-I vector to create the pCold-p30 plasmid. The gene sequences encoding SpyCatcher and ferritin were fused and then inserted into the pET-28a(+) vector to produce the pET-F-np plasmid. Both plasmids were expressed in Escherichia coli upon induction. Subsequently, the affinity chromatography-purified p30 protein was conjugated with ferritin in vitro, and the p30-ferritin (F-p30) nanoparticles were purified by size-exclusion chromatography. The morphology and structural integrity of F-p30 nanoparticles were examined by a particle size analyzer and transmission electron microscopy. Mice were immunized with F-p30 nanoparticles, and the humoral and cellular immune responses were assessed. The results showed that F-p30 nanoparticles were successfully prepared, with the particle size of approximately 20 nm. F-p30 nanoparticles were efficiently internalized by bone marrow-derived dendritic cells (BMDCs) cells in vitro. Compared with the p30 protein alone, F-p30 nanoparticles induced elevated levels of specific antibodies and cytokines in mice and stimulated the proliferation of follicular helper T cell (T_FH) and germinal center B cell (GCB) in lymph nodes as well as CD4⁺ and CD8⁺ T cells in the spleen. In conclusion, we successfully prepared F-p30 nanoparticles which significantly enhanced the immunogenicity of p30 protein, giving insights into the development of vaccines against ASFV.

BACKGROUND: Eucommia ulmoides Oliv. is a medicinal plant native to China, with its bark (Eucommiae Cortex) traditionally being used for medicinal purposes. Previous research has shown that Eucommia male flowers can exert anti-inflammatory, analgesic, antibacterial, and other pharmacological effects, including immune regulation. This study explored the anti-inflammatory effects of the 70% ethanol extract of male flowers (EF) of E. ulmoides in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells and LPS-administered mice. METHODS: Cytotoxicity of EF for RAW 264.7 cells was investigated using Cell Counting Kit-8. The production of proinflammatory mediators, nitric oxide (NO), tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 was determined using enzyme-linked immunosorbent assays. IL-17, IL-23, and IL-10 mRNA levels were determined using quantitative real-time polymerase chain reaction. Activation of the nuclear factor (NF)-κB pathway in RAW 264.7 cells was investigated via Western blotting. In vivo anti-inflammatory effects of EF were studied in an LPS-induced acute inflammation mouse model by analyzing lung tissue histopathology, serum TNF-α and IL-6 levels, and myeloperoxidase (MPO) activity in lung tissue. RESULTS: EF showed no significant cytotoxicity at concentrations from 10 to 60 μg/mL (cell viability > 80%) in the CCK-8 cell viability assay. EF inhibited the RAW 264.7 cell proliferation (EF 60 μg/mL, 120 μg/mL, and 250 μg/mL vs. negative control: 87.31 ± 2.39% vs. 100.00 ± 2.50%, P = 0.001; 79.01 ± 2.56 vs. 100.00 ± 2.50%, P < 0.001; and 64.83 ± 2.50 vs. 100.00 ± 2.50%, P < 0.001), suppressed NO (EF 20 μg/mL and 30 μg/mL vs. LPS only, 288.81 ± 38.01 vs. 447.68 ± 19.07 μmol/L, P = 0.004; and 158.80 ± 45.14 vs. 447.68 ± 19.07 μmol/L, P < 0.001), TNF-α (LPS+EF vs. LPS only, 210.20 ± 13.85 vs. 577.70 ± 5.35 pg/mL, P < 0.001), IL-1β (LPS+EF vs. LPS only, 193.30 ± 10.80 vs. 411.03 ± 42.28 pg/mL, P < 0.001), and IL-6 (LPS+EF vs. LPS only, 149.67 ± 11.60 vs. 524.80 ± 6.24 pg/mL, P < 0.001) secretion, and downregulated the mRNA expression of IL-17 (LPS+EF vs. LPS only, 0.23 ± 0.02 vs. 0.43 ± 0.12, P < 0.001), IL-23 (LPS+EF vs. LPS only, 0.29 ± 0.01 vs. 0.42 ± 0.06, P=0.002), and IL-10 (LPS+EF vs. LPS only, 0.30 ± 0.01 vs. 0.47 ± 0.01, P=0.008) in LPS-stimulated RAW 264.7 cells. EF inhibited the LPS-induced NF-κB p65 (LPS+EF 20 μg/mL and 30 μg/mL vs. LPS only: 0.78 ± 0.06 vs. 1.17 ± 0.08, P < 0.001; and 0.90 ± 0.06 vs. 1.17 ± 0.08, P =0.002) and inhibitor of kappa B (IκBα) phosphorylation (LPS+EF 20 μg/mL and 30 μg/mL vs. LPS only: 0.25 ± 0.01 vs. 0.63 ± 0.03, P < 0.001; and 0.31 ± 0.01 vs. 0.63 ± 0.03, P < 0.001), LPS+EF 30 μg/mL inhibited IκB kinase (IKKα/β) phosphorylation (LPS+EF 30 μg/mL vs. LPS only, 1.12 ± 0.14 vs. 1.71 ± 0.25, P = 0.002) in RAW 264.7 cells. Furthermore, EF 10 mg/kg and EF 20 mg/kg inhibited lung tissue inflammation in vivo and suppressed the serum TNF-α (LPS+EF 10 mg/kg and 20 mg/kg vs. LPS only, 199.99 ± 186.49 vs. 527.90 ± 263.93 pg/mL, P=0.001; and 260.56 ± 175.83 vs. 527.90 ± 263.93 pg/mL, P = 0.005), and IL-6 (LPS+EF 10 mg/kg and 20 mg/kg vs. LPS only, 41.26 ± 30.42 vs. 79.45 ± 14.16 pg/ ml, P = 0.011; and 42.01 ± 26.26 vs. 79.45 ± 14.16 pg/mL, P = 0.012) levels and MPO (LPS+EF 10 mg/kg and 20 mg/kg vs. LPS only, 3.19 ± 1.78 vs. 5.39 ± 1.51 U/g, P = 0.004; and 3.32 ± 1.57 vs. 5.39 ± 1.51 U/g, P = 0.006) activity in lung tissue. CONCLUSIONS EF could effectively inhibit the expression of inflammatory factors and overactivation of neutrophils. Further investigation is needed to evaluate its potential for anti-inflammation therapy.

Adipose tissue-derived stem cell (ASCs) are an attractive source of stem cells with therapeutic applicability in various fields for regenerating damaged tissues because of their stemness characteristics. However, little has reported on evaluating adverse responses caused by human ASC therapy. Therefore, in the present study, a clinical assessment after human ASC transplantation into dogs was undertaken. A total of 12 healthy male dogs were selected and divided into four groups: saline infusion, saline bolus, ASC infusion, and ASC bolus groups. Physical assessment and blood analysis were performed following ASC transplantation, and the concentrations of angiogenic factors, and pro- and anti-inflammatory cytokines were measured by enzyme-linked immunosorbent assay (ELISA). There were no adverse vital sign responses among the dogs. Blood analyses revealed no remarkable complete blood count or serum chemistry results. ELISA results for angiogenic and anti-inflammatory factors including matrix metalloproteinase 9 (MMP9), vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), hepatocyte growth factor (HGF), and interleukin-10 (IL-10) were significantly higher in the two ASCs groups than in the controls. In conclusion, this study demonstrated that transplantation of human ASCs produced no adverse effects and could be used safely in dogs. In addition, human ASCs could be involved in modulating secretions of angiogenic factors including MMP9, VEGF, bFGF, and HGF and anti-inflammatory factor IL-10.

BACKGROUND: Kidney ischemia-reperfusion (IR) via laparotomy is a conventional method for kidney surgery in a mouse model. However, IR, an invasive procedure, can cause serious acute and chronic complications through apoptotic and inflammatory pathways. To avoid these adverse responses, a Non-IR and dorsal slit approach was designed for kidney surgery. METHODS: Animals were divided into three groups, 1) sham-operated control; 2) IR, Kidney IR via laparotomy; and 3) Non-IR, Non-IR and dorsal slit. The effects of Non-IR method on renal surgery outcomes were verified with respect to animal viability, renal function, apoptosis, inflammation, fibrosis, renal regeneration, and systemic response using histology, immunohistochemistry, real-time polymerase chain reaction, serum chemistry, terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining, and Masson's trichrome staining. RESULTS: The Non-IR group showed 100% viability with mild elevation of serum blood urea nitrogen and creatinine values at day 1 after surgery, whereas the IR group showed 20% viability and lethal functional abnormality. Histologically, renal tubule epithelial cell injury was evident on day 1 in the IR group, and cellular apoptosis enhanced TUNEL-positive cell number and Fas/caspase-3 and KIM-1/NGAL expression. Inflammation and fibrosis were high in the IR group, with enhanced CD4/CD8-positive T cell infiltration, inflammatory cytokine secretion, and Masson's trichrome stain-positive cell numbers. The Non-IR group showed a suitable microenvironment for renal regeneration with enhanced host cell migration, reduced immune cell influx, and increased expression of renal differentiation-related genes and anti-inflammatory cytokines. The local renal IR influenced distal organ apoptosis and inflammation by releasing circulating pro-inflammatory cytokines. CONCLUSION: The Non-IR and dorsal slit method for kidney surgery in a mouse model can be an alternative surgical approach for researchers without adverse reactions such as apoptosis, inflammation, fibrosis, functional impairment, and systemic reactions.

Gastroenteropancreatic neuroendocrine neoplam (GEP-NEN) is a rare group of tumors with its incidence rising significantly in recent decades. Because of the late presentation of the disease and limitations in conventional biomarkers, about 50% of GEP-NEN patients manifests advanced disease when diagnosed. Therefore, it is vital to identify circulating biomarkers which can not only be used for early diagnosis but also accurately evaluating the biological behavior of GEP-NEN. This review summarizes the advances of circulating biomarkers in diagnosing and evaluating efficacy of treatment in GEP-NEN. Well-known circulating biomarkers include chromogranin A (CgA), pancreastatin (PST), chromogranin B (CgB), neuron-specific enolase (NSE) and pancreatic peptide(PP). Novel biomarkers including circulating tumor cell(CTC), microRNA and NETest are promising biomarkers with potential clinical benefit, but further researches are needed before their clinical applications.

In 2016, external quality assessment trials for urinalysis and faecal occult blood (FOB) were performed with 1,487 participants in Korea. Urine chemistry and FOB tests were performed three and two times, respectively, whereas urine sediment was evaluated once using photography. Urine chemistry tests consisted of pH, protein, glucose, ketone, bilirubin, blood, urobilinogen, and nitrite levels; leukocyte count; specific gravity. The results of the urine chemistry and specific gravity tests showed accuracy rates of >95%. The accuracy rate of urine sediments was low, especially that for transitional epithelial cells and atypical crystals. In the FOB quality test, all reagents showed accuracy rates of >90%, which suggested the improvement of false-positive reaction. In the FOB quantitative test, discrepant results depending on the instrument used was observed. To compensate for the result differences caused by the stool samples, the results should be reported using another unit (µg/g of stool).

Angiotensin II (Ang II) is involved in endothelium injury during the development of hypertension. Tribulus terrestris (TT) is used to treat hypertension, arteriosclerosis, and post-stroke syndrome in China. The present study aimed to determine the effects of aqueous TT extracts on endothelial injury in spontaneously hypertensive rats (SHRs) and its protective effects against Ang II-induced injury in human umbilical vein endothelial cells (HUVECs). SHRs were administered intragastrically with TT (17.2 or 8.6 g·kg·d) for 6 weeks, using valsartan (13.5 mg·kg·d) as positive control. Blood pressure, heart rate, endothelial morphology of the thoracic aorta, serum levels of Ang II, endothelin-1 (ET-1), superoxide dismutase (SOD) and malonaldehyde (MDA) were measured. The endothelial injury of HUVECs was induced by 2 × 10 mol·L Ang II. Cell Apoptosisapoptosis, intracellular reactive oxygen species (ROS) was assessed. Endothelial nitric oxide synthase (eNOS), ET-1, SOD, and MDA in the cell culture supernatant and cell migration were assayed. The expression of hypertension-linked genes and proteins were analyzed. TT decreased systolic pressure, diastolic pressure, mean arterial pressure and heart rate, improved endothelial integrity of thoracic aorta, and decreased serum leptin, Ang II, ET-1, NPY, and Hcy, while increased NO in SHRs. TT suppressed Ang II-induced HUVEC proliferation and apoptosis and prolonged the survival, and increased cell migration. TT regulated the ROS, and decreased mRNA expression of Akt1, JAK2, PI3Kα, Erk2, FAK, and NF-κB p65 and protein expression of Erk2, FAK, and NF-κB p65. In conclusion, TT demonstrated anti-hypertensive and endothelial protective effects by regulating Erk2, FAK and NF-κB p65.

BACKGROUNDPremature ovarian failure (POF) is a disease that affects female fertility but has few effective treatments. Ovarian reserve function plays an important role in female fertility. Recent studies have reported that hydrogen can protect male fertility. Therefore, we explored the potential protective effect of hydrogen-rich water on ovarian reserve function through a mouse immune POF model.

METHODSTo set up immune POF model, fifty female BALB/c mice were randomly divided into four groups: Control (mice consumed normal water, n = 10), hydrogen (mice consumed hydrogen-rich water, n = 10), model (mice were immunized with zona pellucida glycoprotein 3 [ZP3] and consumed normal water, n = 15), and model-hydrogen (mice were immunized with ZP3 and consumed hydrogen-rich water, n = 15) groups. After 5 weeks, mice were sacrificed. Serum anti-Müllerian hormone (AMH) levels, granulosa cell (GC) apoptotic index (AI), B-cell leukemia/lymphoma 2 (Bcl-2), and BCL2-associated X protein (Bax) expression were examined. Analyses were performed using SPSS 17.0 (SPSS Inc., Chicago, IL, USA) software.

RESULTSImmune POF model, model group exhibited markedly reduced serum AMH levels compared with those of the control group (5.41 ± 0.91 ng/ml vs. 16.23 ± 1.97 ng/ml, P = 0.033) and the hydrogen group (19.65 ± 7.82 ng/ml, P = 0.006). The model-hydrogen group displayed significantly higher AMH concentrations compared with that of the model group (15.03 ± 2.75 ng/ml vs. 5.41 ± 0.91 ng/ml, P = 0.021). The GC AI was significantly higher in the model group (21.30 ± 1.74%) than those in the control (7.06 ± 0.27%), hydrogen (5.17 ± 0.41%), and model-hydrogen groups (11.24 ± 0.58%) (all P < 0.001). The GC AI was significantly higher in the model-hydrogen group compared with that of the hydrogen group (11.24 ± 0.58% vs. 5.17 ± 0.41%, P = 0.021). Compared with those of the model group, ovarian tissue Bcl-2 levels increased (2.18 ± 0.30 vs. 3.01 ± 0.33, P = 0.045) and the Bax/Bcl-2 ratio decreased in the model-hydrogen group.

CONCLUSIONSHydrogen-rich water may improve serum AMH levels and reduce ovarian GC apoptosis in a mouse immune POF model induced by ZP3.

OBJECTIVETo explore the mechanism of the protective effects of Panax notoginseng saponins (PNS) on kidney in diabetic rats.

METHODSDiabetic rat model was obtained by intravenous injection of alloxan, and the rats were divided into model, PNS-100 mg/(kg day) and PNS-200 mg/(kg day) groups, 10 each. Another 10 rats injected with saline were served as control. Periodic acid-Schiff staining and immunological histological chemistry were used to observe histomorphology and tissue expression of bone morphogenetic protein-7 (BMP-7). Silent information regulator 1 (SIRT1) was silenced in rat mesangial cells by RNA interference. The mRNA expressions of SIRT-1, monocyte chemoattractant protein-1 (MCP-1), transforming growth factor β1 (TGF-β1) and plasminogen activator inhibitor-1 (PAI-1) were analyzed by reverse transcription polymerase chain reaction. The protein expressions of SIRT1 and the acetylation of nuclear factor κB (NF-κB) P65 were determined by western blotting. The concentration of MCP-1, TGF-β1 and malondialdehyde (MDA) in culture supernatant were detected by enzyme-linked immuno sorbent assay. The activity of superoxide dismutase (SOD) was detected by the classical method of nitrogen and blue four.

RESULTSIn diabetic model rats, PNS could not only reduce blood glucose and lipid (P<0.01), but also increase protein level of BMP-7 and inhibit PAI-1 expression for suppressing fibrosis of the kidney. In rat mesangial cells, PNS could up-regulate the expression of SIRT1 (P<0.01) and in turn suppress the transcription of TGF-β1 (P<0.05) and MCP-1 (P<0.05). PNS could also reverse the increased acetylation of NF-κB p65 by high glucose. In addition, redox regulation factor MDA was down-regulated (P<0.05) and SOD was up-regulated (P<0.01), which were both induced by SIRT1 up-regulation.

CONCLUSIONSPNS could protect kidney from diabetes with the possible mechanism of up-regulating SIRT1, therefore inhibiting inflammation through decreasing the induction of inflammatory cytokines and TGF-β1, as well as activating antioxidant proteins.

OBJECTIVETo investigate the effects of hydro-alcoholic extract of Launaea acanthodes, a blood glucose lowering plant in folk medicine of Iran, on the structure of seminiferous tubules and serum gonadotropin and testosterone levels in hyperglycemic rats.

METHODSTwenty-four Wistar rats were randomly allocated into 4 groups (n=6): control, streptozotocin (STZ), STZ + insulin [STZ + Ins, 5 IU/(kg•day)], and STZ + Launaea acanthodes extract [STZ + Ext, 150 mg/(kg•day)]. Blood samples were collected at the 2nd and 4th weeks for detection of testosterone, follicle stimulating hormone (FSH) and luteinizing hormone (LH) with enzyme-linked immuno sorbent assay (ELISA), and the right testes of rats were removed at the 7th week for the evaluation of diameter and wall thickness of seminiferous tubules and number of Leydig cells using unbiased stereological techniques.

RESULTSIn comparison with the control group, at the 2nd week FSH (0.45 vs 0.03, 0.02, 0.02 IU/L in STZ, STZ + Ins and STZ + Ext groups, respectively) and LH (1.02 vs 0.37, 0.2, 0.29 IU/L) showed significant decreases (all P<0.05) and testosterone (4.2 vs 8.37, 7.78, 11.8 ng/mL) showed a remarkable increase (all P<0.05). The levels of these hormones became closer in the STZ + Ext and the STZ + Ins groups to the control at the 4th week. A significant decrease in diameter and wall thickness of seminiferous tubules and number of Leydig cells were observed in the STZ group as compared with the control (P<0.01).

CONCLUSIONSAdministration of Launaea extract demonstrated a beneficial impact on the protection of testis from pathogenic and degenerative effects of hyperglycemia which may be partly due to its potential antioxidative effects.
