ABSTRACT
Objective To investigate of effect and mechanism of honokiol against acute lung injury (ALI) induced by lipopolysaccharide (LPS).Methods Forty SPF BALB/c mice were randomly divided into 5 groups (N =8),normal control group,LPS group,low-and high-dose magnolol groups,and dexamethasone group.The mouse model of ALI was induced by LPS.After intraperitoneal injection of honokiol,we detected neutrophil count,concentration of albumin,and pulmonary myeloperoxidase (MPO) activity in bronchoalveolar lavage fluid (BALF)as well as alveolar permeability.We also detected the levels of malondialdehyde (MDA),protein carbonyl content(PCC),reactive oxygen species (ROS) and glutathione(CAT),and the activities of superoxide dismutase (SOD),catalase,glutathione peroxidase (GPx),and glutathione-S-transferase(GST) in lung tissue of mice.Results In the LPS group,the neutrophil count,albumin concentration,MPO activity and Evans blue (EB)content were increased (P ＜ 0.05),and anti-oxidase activity was decreased significantly (P ＜ 0.05).After treatment with honokiol,the neutrophil count,albumin concentration,MPO activity,EB content,and lipid peroxidation level were decreased significantly,and the activities of antioxidant enzymes were increased significantly (P ＜ 0.05).Conclusion Honokiol has protective effects against LPS-induced acute lung injury through inhibiting oxidative stress.
ABSTRACT
Objective To observe the clinical efficacy of Oseltamivir combined with Chinese medicine for the treatment of influenza. Methods One hundred and ninety-seven cases confirmed as influenza were randomly divided into treatment group ( N=101) and control group ( N=96) . Both groups were given conventional symptomatic and supportive treatment. Additionally, the treatment group received Oseltamivir and Chinese medicine based on syndrome differentiation, and the control group was given Oseltamivir orally. The treatment lasted 5 days. The clinical outcomes included incidence of flu symptoms, time for body temperature decreasing to the normal and time for the relief of all symptoms in both groups. Results ( 1) The total effective rate of the treatment group was 98.0%, superior to 91.7%of the control group (P<0.05) . (2) The treatment group had an effect on sub-siding fever and relieving symptoms more quickly than the control group, the differences being significant (P<0.05 or P<0.01) . ( 3) The treatment group could relieve flu symp toms of sore throat, muscular soreness, cough, nasal obstruction and discharging more effectively, and the differences were significant compared with the control group (P<0.05) . Conclusion The overall effect of Oseltamivir combined with Chinese medicine is better than Oseltamivir alone, showing the advantages of subsiding fever in a relatively short period of time and relieving flu symptoms more effectively.
ABSTRACT
[Objective] To observe the therapeutic effect of Ganxian Granules Ⅰ (mainly composed of Radix Stephani-ae Tetrandrae, Semen Persicae and Radix Notoginseng) for the treatment of liver fibrosis induced by chronic virus hepatitis. [Methods] Two hundred cases of liver fibrosis induced by chronic virus hepatitis were randomized into group A (n = 120) and group B ( n = 80). Group A received Ganxian Granules Ⅰ 10g per day, tid, and group B received Dahuang Zhechong Pills 9g per day, tid for half a year. The therapeutic effect in the two groups was evaluated after treatment. The changes of hepatic function and serum levels of hyaluronidase (HA) , laminin (LN) and type Ⅲ precolla-gen ( PC Ⅲ) were compared before and after treatment. Meanwhile, type B ultrasonographic results and hepatic pathologic features were observed. [Results] The total therapeutic effective rate was 87.5% in group A, higher than 70.0% in group B ( P 0.05). Group A had a better effect in improving the hepatic function than group B (P
