Tripterygium wilfordii has exihibited multiple pharmacological activities, such as anti-inflammatory, immune modulation, anti-tumor and anti-fertility. T. wilfordii have been used for the therapy of inflammation and autoimmune diseases including rheumatoid arthritis, immune complex nephritis and systemic lupus erythematosus clinically. However, it is well known that T. wilfordii has small margin between the therapeutic and toxic doses and could cause serious injury on digestive, reproductive and urogenital systems. Among all the organs, liver is one of the most remarkable targets of T. wilfordii-induced toxicities, and the damage is more serious than others. It is generally accepted that T. wilfordii-induced liver injury is a result of the combined effects of toxic elements of T. wilfordii. It is reported in several studies that the mechanism of T. wilfordii-induced liver injury may be related to lipid peroxidation, cell apoptosis and immune damage, and so on. Licorice is one of the most commonly used Chinese herbal medicine, with effects of heat- clearing and detoxicating, anti-inflammatory and hepatoprotective, reconciling various drugs, and so on. Licorice often accompany T. wilfordii in clinical application which can significantly reduce the liver injury induced by T. wilfordii. The attenuated effect is exact, but the mechanism is still a lack of in-depth study. This paper reviews the studies on T. wilfordii-induced liver injury and the related mechanism as well as licorice and other traditional Chinese medicine accompany T. wilfordii to reduce the injury in recent years, so as to provide reference for related research in the future.

By convenient sampling,thirty MI patients were recruited. Anxiety was assessed by Self-rating Anxiety Scale.Demographic data,disease duration,severity of disease and treatment was surveyed by general condition questionnaire. Results The general score of anxiety in MI patients was 42.17 ± 8.47,which was statistically higher than the norm(P ＜ 0. 05). Anxiety level was found positively correlated with the severity of symptoms.Conclusions Anxiety is generally found in M1 patients,the level of which is higher than the norm. Anxiety level is positively correlated with the severity of symptoms in MI patients.

Objective To launch systematic research on long-term asymptomatic hyperuricemia (HUA) from hemorheological viewpoint,so as to provide references for clinical treatment of asymptomatic HUA.Methods Twenty rats were randomly and evenly divided into normal control group and model group.The rats were intraperitoneally injected with 250 mg/(kg · d) oxonate for 8 weeks to induce the model of asymptomatic HUA.The blood samples were obtained to measure the serum uric acid,hemorheological parameters,oxidative and anti-oxidative indices.Results The aggregation index,haemolysis rate,serum xanthine oxidase (XOD),plasma fibrinogen and blood viscosity significantly increased,while the orientation index,electrophoresis rate,serum superoxide dismutase (SOD),activated partial thromboplastin time (APTT) and prothrombin time (PT) significantly induced.Conclusions The asymptomatic HUA can lead to more serious oxidative stress,deteriorate the hemorheological parameters of red blood cells in rats,and induce higher blood viscosity and coagulation status.The research findings indicate that asymptomatic HUA should be correctly understood and timely intervened in clinical diagnosis.

OBJECTIVETo investigate whether S. aureus could activate NF-κB signaling pathway in human osteoblasts.

METHODSImmunoblot and electrophoretic mobility shift assay were used to detect the degradation of I-κBα and activation of NF-κB in human osteoblasts following infection with S.aureus, respectively, and there were investigated the activated state of NF-κB signaling pathway in human osteoblasts. In addition, enzyme-linked immunosorbent assay was used to measure the secretion of IL-6 in culture supernatants, which was represented as one of important cytokines in osteomyelitis, and an inhibitor of NF-κB, SN50, which was added to human osteoblasts culture prior to 1 hour at 50 µmol/L before the infection of S.aureus, was used to determine whether S.aureus-activated NF-κB signaling pathway regulates IL-6 secretion of human osteoblasts.

RESULTSS.aureus could induce the degradation of I-κBα (I-κBα(15 min)/I-κBα(0 min) = 0.409 ± 0.245 and I-κBα(30 min)/I-κBα(0 min) = 0.061 ± 0.010) and activation of NF-κB in human osteoblasts in a time and dose-dependent manner following infection. In addition, the secretion of IL-6 in the supernatants of human osteoblasts ((2.17 ± 0.11) µg/L) was suppressed by 50 µmol/L SN50 compared to without the addition of SN50 ((3.58 ± 0.31) µg/L) (F = 174.25, P < 0.05).

CONCLUSIONSS.aureus could activate NF-κB signaling pathway in human osteoblasts, which could regulate cytokines secretions of human osteoblasts.

Objective To explore the clinical effect of non-invasive positive pressure ventilation(NPPV)for treatment of acute left heart failure after mitral valve replacement. Methods Sixty patients with acute left heart failure after mitral valve replacement in Xinxiang Central Hospital from April 2009 to August 2017 were selected. The patients were divided into control group and NPPV group,with 30 patients in each group. The patients in the control group were treated with double oxygen ab-sorption (mask and nasal catheter),strong heart,diuresis and dilated blood vessels. Based on the treatment of control group, the patients in NPPV group were treated with NPPV therapy. The plasma N-terminal pro-B-type natriuretic peptide(NT-proB-NP)level of patients in the two groups was monitored by rapid determination of immunofluorescence before treatment and 6,24 hours after treatment. The respiratory frequency,blood oxygen saturation,heart rate and oxygen partial pressure monitoring of patients in the two groups was monitored before treatment and 2,6 and 24 hours after treatment. Results The total effective rate of patients in the control group and NPPV group was 92. 4％(26 / 28)and 96. 6％(28 / 29)respectively;there was no sig-nificant difference in the total effective rate between the two groups(χ2 = 1. 25,P > 0. 05). There was no significant difference in the plasma NT-proBNP level between the two groups before treatment (P > 0. 05);the level of NT-proBNP at 6,24 h after treatment was significantly lower than that before treatment in the two groups (P < 0. 05);the level of NT-proBNP of patients in the NPPV group was significantly lower than that in the control group at 6,24 h after treatment (P < 0. 05). There was no significant difference in the respiratory frequency,blood oxygen saturation,heart rate and oxygen partial pressure between the two groups before treatment(P > 0. 05). Compared with before treatment,the respiratory frequency and heart rate of patients were decreased and the blood oxygen saturation,oxygen partial pressure were increased at 2,6,24 h after treatment in the two groups (P < 0. 05). There was no significant difference in the oxygen partial pressure between the two groups at 2 h after treat-ment(P > 0. 05);the oxygen partial pressure of patients in the NPPV group was significantly higher than that in the control group at 6,24 h after treatment(P < 0. 05);there was no significant difference in the respiratory frequency,blood oxygen satu-ration and heart rate between the two groups at each time piont after treatment(P > 0. 05). Conclusion NPPV is an effective treatment for acute left heart failure after mitral valve replacement.
