Objective To explore the role of nuclear factor kappa B(NF-KB)in the pathogenesis of chronic obstructive pulmonary disease(COPD)and the therapeutic efects of glucocorticoid.Methods Twenty-four Wistar rats were randomly divided into three groups,ie.normal control,COPD model and prednisone preventive treatment group.Rat COPD model Was established by exposing the rats to cigarette smoke daily.Prednisone Was given through stomachal injection on altemate days.After COPD model Was set up,bronchoalveolar lavage(BAL)Was performed.Total cell counts and neutrophil counts in BALF were examined.Pathological changes of lung tissue Was observe0 by hematoxylin-eosin staining.The morphological indices of pulmonary emphysema(MLI,MAN and PAA)Was measured by a computerizedimage analyzer and compared in three groups.NF-KB expression in lung tissues were detected by immunohistochemistry assay.Rults Emphysema Was confirmed by three morphological indices in COPD model group compared to those of normal control group[MLI:(97.97±11.10)×10-6m vs (47.23±2.80)×10-6 m,MAN:(95.98±l4.89)×106 /m vs (164.21±9.30)×106 /m ,PAA:(64 ±5.7)%vs (44±2.7)%,Plt;0.01].Total cell counts and neutrophil counts in BALF of COPD model group were significantly higher than those of control group[(5.76±0.29)×108/L vs (1.64±0.12)×108/L,(1.26±0.25)×108/L vs (0.099±0.065)×108/L,Plt;0.01].After the preventive treatment with prednisone,MLI,MAN and PAA were significantly changed[(57.66±4.62)×10-6mvs (97.97±11.10)×10-6m,(111.40±16.92)×106个/m2 vs (95.98±14.89)×106个/m2,Plt;0.01;(58±6.1)% vs (64±5.7)%,Plt;0.05],which indicated that airway inflammation and emphysematous injury in preventive treatm ent group were milder than those of COPD mode1.Total ceil counts and neutrophil countsin BALF were found in preventive treatment group as compared to those of COPD model[[(3.18±0.29)×108/L vs (5.76±0.29)×108/L,(0.57±0.12)×108/L vs (1.26±0.25)×108/L,Plt;0.01].The percentage of positive cells of NF-KB nuclear staining in bronchiolar epithelial ceils was significantly increased in the COPD group than that in the control group[(29.02±1.25)% vs (12.17±1.13)%,Plt;0.01],but was significantly decreased in the preventive treatment group[(19.23±1.18)%vs (29.02±1.25)%,Plt;0.01].Conclusions NF-KB may be responsible for the persistence and amplification of inflammation in COPD through neutrophil recruitment and activation.Prednisone may suppress airwayinflammation in COPD by inhibiting NF-KB.
OBJECTIVE To discuss the methods selection on treatment of body surface hemangioma. METHODS From February 1983 to March 2001, 265 patients with different types of body surface hemangioma were treated with prednisone in 94 cases, laser in 102 cases, and plastic surgery operation in 69 cases respectively. RESULTS Followed up 6 months to 15 years, 70 cases with prednisone treatment were cured (74.5%), which meaned the hemangioma was totally removed and no recurrence in 6 months follow-up, 51 cases with laser treatment were cured (50%), while in the plastic surgery operation group, the cure rate was 98.6% (68 cases). CONCLUSION Treatment with prednisone, laser or plastic surgery operation are all effective to body surface hemangioma and proper treatment method should be selected according to different period and different type of hemangioma to improve the therapeutic effectiveness.
ObjectiveTo optimize the therapy protocols of high dose prednisone combined with topiramate (TPM) in children with infantile spasms (IS). MethodsSixty cases were collected in our hospital from September 2012 to September 2013 and randomly divided into two groups(n=30) and followed-up for more than 6 months.The spasms were assesses by video-electroencephalogram (VEEG) monitoring including awake and asleep states before treatment, after two weeks of therapy and the end of the courses respectively.And the Gessel developmental quotient (DQ) scores were performed before treatment and after six months of therapy. ResultsFor the unresponders to high dose prednisone in one week of therapy, there were 46.67%and 60.00% in test group higher than 31.25% and 37.50% in control group respectively in 2 week and in the end of treatment.And the rate of complete resolution of hypsarrhythmia in the test group was 46.67% and 60.00% higher than 25.00% and 37.50% in control group respectively in 2 week and in the end of treatment.But there were no statistical significances between two groups(P >0.05).The incidence of side effects(83.33% vs. 80.00%) and the relapse rate(39.14% vs. 40.00%), were not statistically significant between two groups(P >0.05).The responsive rates for the cases with the lead time within 2 months higher than beyond 2 months in two groups respectively in 2 weeks and in the end of treatment. ConclusionsThe protocol of the test group was superior to that of the control group.The responsive rates of children within 2 months of lead time were higher than beyond 2 months, which indicates that early diagnosis and early treatment would improve efficacy and have an important influence on the prognosis of IS.
