OBJECTIVE: To observe the effects of glycyrrhizin on hydroxyproline(HYP),hyaluronic acid(HA) and laminin(LN) in pulmonary fibrosis model rats.METHODS: A total of 80 SD rats were randomly divided into normal control group,model group,hormone group(prednisone 0.6 mg?kg?d-1),and glycyrrhizin group(10 g?kg?d-1).The latter 3 groups were established into pulmonary fibrosis model with bleomycin,and on the second day after modelling,each group was given corresponding test drugs(the normal group and model group were treated with same amount of normal saline) then the changes of the levels of HYP in lung tissues,and serum levels of HA and LN in every group were observed at 7 and 28 days respectively.RESULTS: In glycyrrhizin group compared with model group,the contents of HYP in lung tissue,HA and LN in serum decreased significantly(P

OBJECTIVE: To explore the effect of glycyrrhizin on eotaxin expression in lung tissue from asthmatic model mice and the mechanism for glycyrrhizin to treat bronchial asthma.METHODS: The mice were randomized to asthma model group,prednisone-treated group and glycyrrhizin-treated group and normal control group.Egg protein asthma mouse model was established before being giving the corresponding drugs.Then the mice were sacrificed after 4 weeks for the counting of eosinophils in bronchoalveolar lavage fluid(BALF) and detection of Eotaxin expression in lung tissues by immunohistochemistry,with the results compared with normal control group.RESULTS: In glycyrrhizin-treated group compared with model group,the counting of eosinophils in BALF were decreased(P

ObjectiveTo investigate the effects of budesonide inhaled on the levels of interleukin-8 (IL-8), C-reactive protein (CRP) and procalcitonin (PCT) in bronchoalveolar lavage fluid (BALF) of patients with AECOPD treated by using inhalation of budesonide in different doses or by using injection of dexamethasone. MethodsNinety AECOPD patients with mechanical ventilation in ICU ward were enrolled from Jan. 2008 through Sep. 2010. All patients were selected in this study as per the criteria of AECOPD set by the Chinese Medical Association. Ninety AECOPD patients treated with routine therapy were randomly (random number) divided into 3 groups. The patients of group A were given budesonide 2 mg inhaled 1 time/d. The patients of group B was given budesonide 4 mg inhaled 1 time/d. The patients of group C had dexamethasone 2. 5 mg injected 1 time/12h. The changes of IL-8, PCT and CRP in both BALF and serum were respectively detected in three groups at the beginning of treatment, and 3 days and 7days after treatment. The detected data of variables were analyzed by SPSS 13.0 package. ResultsThe level of IL-8 in BALF declined in 3days and 7days after treatment, and the magnitude of decrease in the following order:Group B ( budesonide 4mg/d) ＞ Group A ( budesonide 2 mg/d) ＞ Group C ( intravenous dexamethasone)with significant differences among them ( P ＜ 0. 05 ). The decrease in IL-8 in serum showed the similar trend, but there were no statistical differences among them. The CRP and PCT in both BALF and serum had no significant changes. There was a correlation between the concentration of IL-8 in BALF and the duration of mechanical ventilation.Conclusions The treatment with the inhalation of budesonide could more significantly reduced the IL-8 level in BALF compared with intravenous dexamethasone, whereas the CRP and PCT were not changed. The dynamic changes of IL-8 in BALF might be used as an indicator of prognosis in AECOPD patients with mechanical ventilation.

The effect of liquorice on mice model of chronic bronchial asthma was observed, and the levels of serum IFN-? and IL-4 were tested by ELISA. RESULTS: Decreasing inflammatary cells infiltration in pulmonary tissue slices of tiny bronchial wall together with increasing serum IFN-? and decreasing serum IL-4 levels. CONCLUSION: Liquorice can adjust Th_1/Th_2 imbalance and inhibit the airway inflammation.

Aim To investigate whether D-galactose cause osteoporosis and the difference compared with the osteoporosis induced by ovariectomy, and to deter-mine whether ovariectomy coupled with D-galactose ac-celerated the progress of osteoporosis and whether es-trogen had a preventive effect on these osteoporosis models. Methods Sixty SPF mice were randomly divided into six groups , namely sham-operated group, D-galactose group, OVX group, OVX + D-galactose group, OVX + D-galactose + diethylstilbestrol group and D-galactose + diethylstilbestrol group. Seventy days later, the right tibia was processed with undecal-cified sections for bone histomorphometric analysis. Results Compared with the sham-operated group, %Tb. Ar, Tb. Th and Tb. N decrease by 50. 4%, 25. 4%, 50. 9% ( P <0.01 ) respectively, Tb. Sp in-creased by 169. 4% (P <0.05), Oc. pm, Oc. No. ,%Oc. S, Oc. N/mm which reflected bone absorption significantly increased ( P < 0.01 ) , and % L. Pm, MAR, BFR/TV, BFR/BV, BFR/BS which reflected bone formation significantly decreased ( P <0.01 ) in OVX group. %Tb. Ar decreased by 30. 4% in D-ga-lactose group, but there was no statistically significant difference. However, the four parameters reflected the bone absorption in D-galactose group increased signifi-cantly ( P<0.05 ) , while the four parameters reflected bone formation decreased significantly ( P < 0.05 ) . OVX+D-galactose group has obvious performance of osteoporosis, but there was no significant difference compared to OVX group, nor to D-galactose group. Estrogen had significant preventive effect on related pa-rameters of osteoporosis induced by D-galactose and o-variectomy coupled with D-galactose. ConclusionsOsteoporosis model of mice can be established by OVX, D-galactose and OVX +D-galactose. Estrogen can effectively prevent bone loss induced by D-galac-tose and OVX+ D-galactose.

Objective To explore the effect of ginseng co?enzyme Q10 suncream on the skin damage caused by ul?traviolet ( UV) radiation in mice. Methods 36 mice were randomly assigned to four groups. The mice were shaved on the back and the left untreated side was taken as control group, or was treated with UV as model group. Before treated with UV, the mice were painted with suncream containing ginseng co?enzyme Q10 , or octyl methoxycinnamate as positive con?trols. The mice were treated for 8 weeks. At the end of the experiment, blood samples of all mice were collected from the eyes, then subjected to cell counting or biochemical measurements, and skin samples were cut for pathological examina?tion. Results Compared with the control group, there was a significant increase in white blood cell counts ( P<0?05 ) and MDA content ( P<0?05 ) , and declined serum levels of SOD ( P <0?05 ) and GSH?Px ( P <0?05 ) in the model group, and the skin was rough and wrinkled with stratum corneum exfoliation. Compared with the model group, the mice of ginseng co?enzyme Q10 suncream group had significantly lower white blood cell count ( P<0?05 ) and MDA content ( P<0?05), and increased serum levels of T?SOD(P<0?05) and red blood cell counts (P<0?05). The skin had no rough? ness and wrinkles and without stratum corneum exfoliation. Compared with the model group, the positive control group showed significantly decreased white blood cell count (P<0?05) and MDA content (P<0?05), and increased serum lev?els of GSH?Px(P<0?05). The skin had no roughness and wrinkles and no stratum corneum exfoliation. However, there was no significant difference between the ginseng co?enzyme Q10 suncream group and positive control group. Conclusions Ginseng co?enzyme Q10 suncream shows satisfactory preventive effects on the UV radiation?induced skin damage in mice, similar to the preventive effects of the octyl methoxycinnamate?containing sunsream.

Objective:This study was conducted to investigate the levels of IL-23 and IL-17 in sera and tumor tissues and to ana-lyze their association with clinico-pathological parameters in patients with colorectal cancer (CRC). Methods:A total of 24 healthy sub-jects and 56 patients with CRC were recruited in this study. Enzyme-linked immunosorbent assay was performed to measure the concen-trations of IL-23 and IL-17 in the sera of CRC patients and healthy controls and in cultured normal tissues and tumor tissues from CRC patients. Results:The levels of serum IL-23 and IL-17 were significantly higher in CRC patients than in healthy controls (P<0.01). The supernatant levels of IL-23 and IL-17 in tumor tissues were significantly higher than in normal tissues (P<0.05). Serum IL-17 level was correlated with tumor location, lymph node metastasis, and TNM stage (P<0.05), whereas serum IL-23 level showed no correlation with all clinico-pathological parameters (P>0.05). Tumor supernatant IL-17 level was correlated with tumor differentiation, lymph node metastasis, and TNM stage (P<0.05), whereas tumor supernatant IL-23 level was correlated only with TNM stage (P<0.05). Conclu-sion:IL-23 and IL-17 may be involved in the immuno-pathogenesis of CRC progression.
