To explore the therapeutic effect of honokiol on particulate matter 2.5 (PM2.5)-induced lung injury in asthmatic mice and the possible mechanisms.
 Methods: A total of 32 BALB/C mice were randomly divided into four groups: a normal saline group, a model group, a PM2.5 group and a honokiol group (n=8 in each group). The asthma mouse model was established by ovalbumin treatment. The mice were treated with physiological saline, ovalbumin, PM2.5 and honokiol, respectively. Lung tissues and serum were collected. The pathological changes of lung tissues were evaluated. The levels of inflammatory cytokines in bronchoalveolar lavage fluid (BALF) and serum were measured and the expressions of Toll like receptor 4 (TLR4), nuclear factor kappa B (NF-κB), retinoid-related orphan receptor gamma-t (RORγt) and forkhead box protein 3 (Foxp3) in lung tissues were detected.
 Results: 1) The lung tissues of mice in the asthma group showed obvious pathological changes and inflammatory state, suggesting that the asthma model was established successfully. PM2.5 could aggravate the pathological condition of inflammatory injury in lung tissues in asthmatic mice. 2) Compared to the PM2.5 group, the pathological symptoms in the lung tissues were alleviated in the honokiol group and the percentage of inflammatory cells in BALF and the levels of inflammatory cytokines in BALF and serum were significantly reduced (all P<0.05). 3) Compared to the PM2.5 group, the expressions of TLR4, NF-κB (p-p65) and RORγt in lung tissues were significantly decreased, while the expression of Foxp3 was increased; the ratio of RORγt/Foxp3 was also decreased in the honokiol group (all P<0.05).
 Conclusion: Honokiol can resist lung injury induced by PM2.5 in asthmatic mice. These effects are through inhibiting TLR4-NF-κB pathway-mediated inflammatory response or regulating the balance of Th17/Treg cells.

OBJECTIVESTo investigate the effect of Shenfu Injection (, SFI) on inflammatory factors in patients with acute myocardial infarction complicated by cardiogenic shock (CS) treated with and intra-aortic balloon pump (IABP).

METHODSThis study enrolled 60 patients with ST-segment elevation myocardial infarction (STEMI) complicated by CS. Patients underwent IABP and emergency percutaneous coronary intervention (PCI) were randomly divided into two groups by random number table with 30 cases in each group, one given Sfitreatment (100 mL/24 h), one not. The two groups were then compared in a clinical setting for left ventricular function, biochemical indicators and Inflammatory factors, including C-reactive proteins (CRP), interleukin-1 (IL-1) and tumor necrosis factor alpha (TNF-α). Major adverse cardiac and cerebrovascular events (MACCE) events were compared between patients of the two groups both in-hospital and in follow-ups.

RESULTSThe IABP support treatment times of patients in the IABP+Sfigroup were signifificantly shorter than the IABP group (52.87±28.84 vs. 87.45±87.31, P=0.047). In the patients of the IABP+Sfigroup, the CRP peak appeared in 24 h after PCI operation. The CRP peak in the patients of the IABP+Sfigroup was signifificantly lower than that in the IABP group (31.27±3.93 vs. 34.62±3.47, P=0.001). The increases in range of TNF-α in the patients of the IABP+Sfigroup were signifificantly lower than those of the IABP group (182.29±22.79 vs. 195.54±12.02, P=0.007). The increases in range of IL-1 in the patients of the IABP+Sfigroup were signifificantly lower than those of the IABP group (214.98±29.22 vs. 228.60±7.03, P=0.019). The amplitude elevated TNF-α 72 h after admission was an independent risk factor of in-hospital MACCE events (OR 0.973, 95% CI 0.890-0.987, P=0.014) in patients with STEMI and CS.

CONCLUSIONPatients with STEMI complicated by CS treated by IABP and Sfihad a reduced inflammatory reaction, a reduced dependence of CS on IABP and shortened the course of disease.

OBJECTIVETo investigate the action of Shen-Fu Injection (SFI) in regulating the expression of the serum complements and inflammatory cytokines synthesized and released in response to the stress of global ischemia accompanying cardiac arrest (CA) and resuscitation.

METHODSThirty pigs were randomly divided into the sham (n=6) and 3 returns of spontaneous circulation (ROSC) groups (n=24). After 8-min untreated ventricular fibrillation and 2-min basic life support, 24 pigs of the ROSC groups were randomized into three groups (n=8 per group), which received central venous injection of SFI (SFI group), epinephrine (EP group), or saline (SA group). Hemodynamic status and blood samples were obtained at 0, 0.5, 1, 2, 4, 6, 12, and 24 h after ROSC.

RESULTSSerum concentrations of specific activation markers of the complement system C3, C4 and C5b-9 were increased during cardiopulmonary resuscitation through 24 h after ROSC. There were intense changes of various pro-inflammatory cytokines and anti-inflammatory cytokines as early as 0.5 h after CA. Compared with the EP and SA groups, SFI treatment reduced the proinflammatory cytokines levels of interleukin (IL)-6, IL-8 and tumor necrosis factor α (TNF-α, P<0.05), and increased the anti-inflammatory cytokine levels of IL-4 and IL-10 (P<0.05). Further, SFI treatment decreased the values of C3, C4 and C5b-9 compared with the EP and SA groups.

CONCLUSIONSSFI, derived from the ancient Chinese medicine, has significant effects in attenuating post-resuscitation immune dysfunction by modulating the expression of complements and cytokines levels. The current study provided an experimental basis for the clinical application of a potential pharmacologic target for post resuscitation immune dysfunction.

BACKGROUND/AIMS: The purpose of this study was to determine the correlations between inflammatory factors-including absolute lymphocyte count, lactate dehydrogenase, beta2-microglobulin, albumin, C-reactive protein, and ferritin-and the prognosis for survival in patients with multiple myeloma (MM) treated with induction chemotherapy containing thalidomide and who underwent autologous stem cell transplantation (ASCT). METHODS: Data from patients at 13 university hospitals in South Korea were collected retrospectively between December 2005 and May 2013. RESULTS: The median age of the 232 patients was 57 years (range, 33 to 77) and the male to female ratio was 1.09:1. In the multivariate analysis, fewer than two combined abnormal inflammatory factors was the only independent prognostic factor for superior progression-free survival (relative risk [RR], 0.618; 95% confidence interval [CI], 0.409 to 0.933; p = 0.022), and platelet count > 100 x 109/L and fewer than two combined abnormal inflammatory factors were independent prognostic factors for superior overall survival (RR, 4.739; 95% CI, 1.897 to 11.839; p = 0.001 and RR, 0.263; 95% CI, 0.113 to 0.612; p = 0.002, respectively). CONCLUSIONS: Patients with two or more than two combined inflammatory factors who were treated with thalidomide induction chemotherapy and who underwent ASCT showed significantly shorter survival compared to those with fewer than two combined inflammatory factors. These results could be helpful for predicting prognosis in patients with MM.

BACKGROUND/AIMS: Aims: Inflammation is an important factor in renal injury. Ferritin, an inflammatory marker, is considered an independent predictor of rapid renal progression in patients with chronic kidney disease. However, the relationship between ferritin and residual renal function (RRF) in patients undergoing peritoneal dialysis (PD) remains unclear. METHODS: We reviewed the medical records of patients who started PD between June 2001 and March 2012 at Soonchunhyang University Bucheon Hospital, Korea. A total of 123 patients were enrolled in the study. At 1 month after the initiation of PD, RRF was determined by a 24-hour urine collection and measured every 6 months thereafter. Clinical and biochemical data at the time of the initial 24-hour urine collection were considered as baseline. RESULTS: The RRF reduction rate was significantly greater in patients with high ferritin (ferritin > or = 250 ng/mL) compared with those with low ferritin (ferritin < 250 ng/mL; -1.71 +/- 1.36 mL/min/yr/1.73 m2 vs. -0.84 +/- 1.63 mL/min/yr/1.73 m2, respectively; p = 0.007). Pearson correlation analysis revealed a significant negative correlation between the baseline serum ferritin level and the RRF reduction rate (r = -0.219, p = 0.015). Using multiple linear regression analysis and adjusting for other risk factors, baseline serum ferritin was an independent factor for the RRF reduction rate (beta = -0.002, p = 0.002). CONCLUSIONS: In this study we showed that a higher ferritin level was significantly associated with a more rapid RRF decline in patients undergoing PD.

OBJECTIVEBuckwheat has been considered as a potential source of nutraceutical components on the world market of probiotic foodstuffs. The purpose of this study was to evaluate the effects of tartary buckwheat (Fagopyrum tataricum) sprouts on oxidation and pro-inflammatory mediators.

METHODSThe anti-oxidant effects of buckwheat extract (BWE) and rutin were evaluated by using 1,1-diphenyl-2-picrylhydrazyl (DPPH)- and nitric oxide (NO)-scavenging activities, serum peroxidation and chelating assays. Lipopolysaccharide (LPS)-stimulated RAW264.7 cells were used to evaluate anti-inflammatory activities of buckwheat and rutin. NO production in LPS-stimulated RAW264.7 cells was determined by using Griess reagent. The expressions of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), nuclear factor-kappa B (NF-κB) p65 subunit in cytosolic and nuclear portions were determined by Western blot analysis. Also, the production of inflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) was determined by enzyme-linked immunosorbent assay.

RESULTSInhibitory concentration 50 values for DPPH- and NO-scavenging activities of BWE were 24.97 and 72.54 μg/mL respectively. BWE inhibited serum oxidation and possessed chelating activity. Furthermore, BWE inhibited IL-6 and TNF-α production in LPS-stimulated RAW264.7 cells. Also, BWE inhibited iNOS and COX-2 expression and NF-κB p65 translocation.

CONCLUSIONBuckwheat sprouts possessed strong antioxidant activity and inhibited production of pro-inflammatory mediators in the applied model systems. Thus, buckwheat can be suggested to be beneficial in inflammatory diseases by inhibiting the free radicals and inflammatory mediators.

INTRODUCTIONThe role of soluble OX40 ligand (sOX40L) in adult bronchial asthma is unclear. This study aims to determine the serum concentrations of sOX40L in adult patients with bronchial asthma, and discussed its relationship with pulmonary function.

MATERIALS AND METHODSWe measured the pulmonary function using the spirometer and detected the serum concentrations of sOX40L by enzyme linked immunosorbent assay (ELISA) in 19 healthy persons in the control group, 58 acute asthmatic adult patients who were grouped according to their disease severity: 18 mild grade, 24 moderate grade, 16 severe grade, and 24 persons in a stable asthmatic group.

RESULTSThe serum concentrations of sOX40L in asthmatic adult patients (6.80 ± 4.95 ng/L) were distinctly higher than those in the control group (3.98 ± 2.83 ng/L, P <0.05), and they were negatively correlated with pulmonary function indexes (FEV1%, FVC%, FEV1/FVC) (r = -0.754, P <0.01, r = -0.557, P <0.01, r = -0.457, P <0.01, respectively). Moreover, the serum concentrations of sOX40L showed obvious differences among control, mild, moderate, and severe groups (3.98 ± 2.83, 4.87 ± 1.89, 6.97 ± 5.91, 8.71 ± 5.18 ng/L, respectively; P <0.01). The concentrations of sOX40L decreased to the same extent as the control group after therapeutic treatments were provided to the asthmatic adult patients.

CONCLUSIONThe concentrations of sOX40L were found to be high in adult asthmatic patients and were associated with the severity of the disease. Therefore, sOX40L could be a potential inflammatory mediator in the pathogenesis of asthma.

OBJECTIVETo explore the correlations between serum uric acid (UA) levels and the clinical and cerebrospinal fluid (CSF) parameters of multiple sclerosis (MS).

METHODSThe medical reports of 47 MS patients admitted to Peking Union Medical College Hospital during 2008 and 2010 were reviewed. And 49 age- and gender-matched cerebral infarction patients were enrolled as control. The mean serum UA level of the MS patients was compared with that of the control group. The correlations between the UA levels and the clinical parameters including gender, disease duration, relapse rate, and disease disabilities as assessed by the Expanded Disability Status Scale score, were explored. Forty-one patients had CSF examinations. The correlations between the UA levels and the CSF parameters reflecting inflammation and tissue damage, including CSF protein, white blood cell count, oligoclonal band, 24-hour IgG index, and myelin basic protein, were also investigated.

RESULTSThe mean serum UA level in the MS patients was lower than that in the control group (247.75±52.59 µmol/L vs. 277.94±74.33 µmol/L, P=0.025) and inversely correlated with the relapse rate (P=0.049). MS patients with lower serum UA levels tended to have higher white blood cell counts and myelin basic protein level. But there was no correlation between CSF protein levels (r=0.165, P=0.273), white blood cell counts (r=-0.051, P=0.732), IgG index (r=0. 045, P=0.802), or myelin basic protein level (r=-0.248, P=0.145) and the serum UA level, respectively.

CONCLUSIONIn MS patients, UA levels might partly reflect the extent of disability and inflammation.

This experiment was conducted to assess the changing patterns and relative values of acute phase proteins and inflammatory cytokines in experimental caprine coccidiosis. Eighteen newborn kids were allocated to 3 equal groups. Two groups, A and B, were inoculated with a single dose of 1x10(3) and 1x10(5) sporulated oocysts of Eimeria arloingi, respectively. The third group, C, received distilled water as the control. Blood samples were collected from the jugular vein of each kid in both groups before inoculation and at days 7, 14, 21, 28, 35, and 42 post-inoculation (PI), and the levels of haptoglobin (Hp), serum amyloid A (SAA), TNF-alpha, and IFN-gamma were measured. For histopathological examinations, 2 kids were selected from each group, euthanized, and necropsied on day 42 PI. Mean Hp concentrations in groups A and B (0.34 and 0.68 g/L) at day 7 PI were 3.2 and 6.3 times higher than the levels before inoculation. The mean SAA concentrations in groups A and B (25.6 and 83.5 microg/ml) at day 7 PI were 4.2 and 13.7 times higher than the levels before inoculation. The magnitude and duration of the Hp and SAA responses correlated well with the inoculation doses and the severity of the clinical signs and diarrhea in kids. These results were consistent with the histopathological features, which showed advanced widespread lesions in group B. In both groups, significant correlations were observed for TNF-alpha and IFN-gamma with SAA and Hp, respectively. In conclusion, Hp and SAA can be useful non-specific diagnostic indicators in caprine coccidiosis.

OBJECTIVETo study the effects of conventional mechanical ventilation (CMV) with low tidal volume on developmental porcine lungs by examining the expression of growth factors and inflammatory mediators.

METHODSTwelve preterm piglets born at 99 days of gestational age, 12 term neonatal piglets and 11 young piglets (4-5-weeks old) were randomly placed on CMV or were not ventilated (control group). The ventilator settings were adjusted to provide a tidal volume of 6-8 mL/kg in order to maintain a normal blood-gas value. After 6 hrs (preterm piglets) or 24 hrs (neonatal and young piglets) of mechanical ventilation, the mRNA expression of growth factors PDGF-B, IGF-I, KGF, HGF, VEGF and TGF-beta1 and proinflammatory cytokines IL-1beta, IL-6, IL-8 and TNF-alpha in the lung tissue was measured using RT-PCR. Growth factor protein expression was measured with immunohistochemistry.

RESULTSIn preterm piglets, the CMV group had increased mRNA expression of PDGF-B (5.11+/-0.10 vs 4.88+/-0.01), IL-1beta (4.95+/-0.27 vs 4.08+/-0.37), IL-6 (4.76+/-0.27 vs 4.00+/-0.28) and IL-8 (5.31+/-0.57 vs 4.15+/-0.46), but decreased IGF-I mRNA expression (3.54+/-0.13 vs 3.80+/-0.11) compared with those in the control group (P<0.05 or 0.01). In term neonatal piglets and young piglets, there were no significant differences in the mRNA expression of growth factors and proinflammatory cytokines between the CMV and control groups.

CONCLUSIONSCMV caused inflammatory injury in immature lungs by increasing the expression of proinflammatory cytokines and PDGF-B and decreasing IGF-I expression. However, CMV had no effects on pulmonary expression of growth factors and inflammatory mediators in term neonatal piglets and young piglets.
