ABSTRACT
Objective To investigate the therapeutic effect of Saccharomyces boulardii on antibiotics associated diarrhea (AAD)in infant pneumonia.Methods 302 hospitalized infant patients (1 month-3 years) with pneumonia but without gastroenteric disease were selected , and antibiotics were administrated intravenously at least 5 continuous days for each patient .Patients were all giv-en antibiotics and randomly divided into three groups:control group with no Saccharomyces boulardii administration ( group A, 60 ca-ses);Saccharomyces boulardii were applied as addition on the occurrence of diarrhea (group B, 92 cases), and Saccharomyces boular-dii and antibiotics were co-administrated (group C, 150 cases).Incidences of AAD in all groups were carefully examined and differ-ences of therapeutic effect between groups were compared and analyzed .Results The incidence of AAD in Group C was significantly lower than that in other groups .In term of diarrhea severity, no significant difference was observed in all groups (P>0.05).Howev-er, duration of diarrhea showed significant different between groups (P<0.001):group A with the longest duration and group C with the shortest .The results indicated that the total efficiency of anti-diarrhea in group C was significantly higher than that in control group (P<0.05).However, group B presented no significant difference compared with neither control group nor group C in term of therapeu -tic effect on diarrhea .Conclusion Administration of Saccharomyces boulardii Sachets could shorten the duration of diarrhea on the oc-currence of AAD in infant pneumonia .According to our results , Saccharomyces boulardii was effective in both preventing the develop-ment of AAD and shortening duration of diarrhea , and therefore improved therapeutic effect on ADD .
ABSTRACT
To explore the effects and mechanism of dexamethasone and ambroxol on expression of surfactant protein (SP)-B mRNA and thyroid transcription factor (TTF)-1 in premature rat lung. Methods Sixteen pregnant Sprague-Dawley rats were randomly divided into four equal groups: two doses of dexamethasone (0.2 mg/kg injected intramuscularly on Day 17 and 18 of pregnancy respectively);single dose of dexamethasone (0.2 mg/kg injected intramuscularly on Day 18 of pregnancy);ambroxol group (100 mg/kg injected intraperitoneally on Day 16, 17 and 18 of pregnancy respectively); and control group (normal saline injected intraperitoneally on Day 16, 17 and 18 of pregnancy respectively). There were four pregnant rats in each group. All of the fetal rats were taken out on Day 19 of pregnancy as the preterm birth model, and 20 fetal rats from each group were randomly selected. The ratio of body weight to fetal lung weight of newborn rats was calculated. Changes in lung morphology were observed under light microscopy and the ratio of alveoli surface area to alveolar septae surface area was calculated. Expression of TTF-1 protein was determined by immunohistochemistry. Expression of SP-B mRNA was detected by reverse transcriptase-polymerase chain reaction. One-way analysis of variance, Student-Newman-Keuls method and Pearson correlation analysis were applied as statistical methods. Results (1) The ratio of body weight to fetal lung weight was (6.5±0.6), (7.9±0.8), (9.5±0.8) and (9.5±0.9) mg/g in two doses of dexamethasone group, one dose of dexamethasone group, ambroxol group and control group respectively (F=67.69,P<0.01). The ratio of two doses and one dose of dexamethasone group was lower than that of control group (q=17.143 and 9.143, all P<0.01) and ambroxol group (q=17.143 and 9.143, all P<0.01). The ratio of two doses dexamethasone group was lower than that of one dose dexamethasone group (q=8.000, P<0.01). (2) The ratio of alveoli surface area to alveolar septae surface area was 2.19±0.15, 1.70±0.18, 1.67±0.13 and 1.08±0.12 in two doses of dexamethasone group, one dose of dexamethasone group, ambroxol group and control group respectively (F=190.85, P<0.01). The ratio of two doses of dexamethasone group, one dose of dexamethasone group and ambroxol group were higher than that of the control group (q=33.639, 18.788 and 17.879, all P<0.01). The ratio of two doses dexamethasone group was higher than that of one dose dexamethasone group (q=14.848, P<0.01). (3) Expression of TTF-1 protein was 0.311±0.018, 0.224±0.019, 0.196±0.013 and 0.191±0.018 in two doses of dexamethasone group, one dose of dexamethasone group, ambroxol group and control group respectively (F=211.69,P<0.01). TTF-1 protein expression of two doses and one dose of dexamethasone group were higher than that of control group (q=30.000 and 8.250, all P<0.01) and ambroxol group (q=28.750 and 7.000, all P<0.01). TTF-1 protein expression of two doses dexamethasone group was higher than that of one dose dexamethasone group (q=21.750, P<0.01). (4) Expression of SP-B mRNA was 1.25±0.13, 1.15±0.12, 1.10±0.10 and 1.01±0.12 in two doses of dexamethasone group, one dose of dexamethasone group, ambroxol group and control group respectively (F=14.48, P<0.01). SP-B mRNA expression of two doses of dexamethasone group, one dose of dexamethasone group and ambroxol group were higher than that of control group (q=9.231, 5.385 and 3.462, all P<0.01). SP-B mRNA expression of two doses of dexamethasone group was higher than that of ambroxol group (q=5.769, P<0.01) and one dose of dexamethasone group (q=3.846, P<0.01). (5)TTF-1 expression in two doses of dexamethasone group, one dose of dexamethasone group and control groups was positively correlated with SP-B mRNA expression (r=0.512, 0.597 and 0.449, respectively, all P<0.05). Conclusions Ambroxol can accelerate the maturation of fetal lung with minimal adverse effects on fetal lung weight. Ambroxol might be an alternative to dexamethasone to prevent neonatal respiratory distress syndrome.

ABSTRACT
Objective By making models of premature animal,explores the effects of dexamethasone on the brain development of premature rats and its mechanisms.Methods Eighteen SD rats were randomly divided into high-dexamethasone(H-Dex) group,low-dexamethasone (L-Dex) group and normal saline(NS) control group,with 6 rats in each group.The pregnant rats in L-Dex group were injected with dexamethasone [0.1 mg/(kg·d)] from 16 to 18 days of pregnancy,while the pregnant rats in H-Dex group were injected with dexamethasone [0.5 mg/(kg· d)] ; the pregnant rats in NS control group were injected with 0.9％ NaCl of the same volume.All of the fetal rats were received after administrating caesarean operation on the day 19 of pregnancy.Rats were sacrificed at the directed time and brain tissue was prepared.Histological feature and the water content of the brains were observed.Level of apoptosis was measured by flow cytometry.The expressions of myelin basic protein (MBP) and interleukin(IL)-1β in brain tissue homogenate were detected by ELISA.Results (1) The brain water contents of rats in H-Dex group,L-Dex group and NS control group were (85.94 ± 0.54) ％,(86.08 ± 1.01) ％,(86.94 ± 0.82) ％.Compared with NS control group,the water contents of Dex group were lower (P ＜ 0.05).(2) Glial cells of brain cortex in L-Dex group and H-Dex group were more mature than in NS control group,and the changes in H-Dex group was more significant.(3) The expressions of MBP in brain tissue of H-Dex group,L-Dex group and NS control group were (5.73 ± 1.06) μg/mg,(5.46 ±0.77) μg/mg and (2.42 ±0.52) μg/mg.Compared with NS control group,Dex group was higher(P ＜0.05).While the expressions of IL-1β in brain tissue of H-Dex group,L-Dex group and NS control group were (249.05 ± 11.29) pg/g,(257.47 ± 9.33) and (292.66 ± 21.51) pg/g.Compared with NS control group,Dex group was lower(P ＜ 0.05).There was no significant difference between H-Dex group and L-Dex group(P ＞ 0.05).(4) The level of apoptosis in H-Dex group,L-Dex group and NS control group were (18.07 ± 1.63) ％,(6.88 ± 0.47) ％ and (2.00 ± 0.32) ％.Compared with NS control group,the level of apoptosis in Dex group was higher(P ＜0.05),and H-Dex group was higher than that in L-Dex group.Conclusion (1) Using dexamethasone prophylactic could promote the development of glial cells,reduce the water content,increase the expressions of MBP,and decrease the expressions of IL-1β in brain tissues.It indicates that dexamethasone may play a major role in maturation of fetal brain.(2) Using dexamethasone prophylactic could increase the amounts of the apoptosis cells,and this effect is dose-dependent.It indicates that dexamethasone may have a negative effect on the fetal brain and suggestes that using dexamethasone in premature infant should be cautious,and if it has to,using a lower dose.
ABSTRACT
A LC-MS method was established for the determination of the protein binding rates of oleanolic acid in human plasma and serum albumin. The equilibrium dialysis combined with LC-MS to determine the total concentration in plasma and free drug concentration of oleanolic acid was carried out. The human plasma protein binding rates of oleanolic acid at three concentrations were 79.6%, 81.9% and 63.3%, respectively. The human serum albumin protein binding rates of oleanolic acid at three concentrations were 53.5%, 56.6% and 47.7%, respectively. The method is shown to be simple, accurate, sensitive and specific for the determination of biological samples. The protein binding rates in human plasma and serum albumin were of high strength.
