OBJECTIVETo observe the efficacy of oral Propranolol in the treatment of infantile subglottic hemangioma.

METHODSEleven children (6 females and 5 males) with a median age at onset of treatment being 4 months were included in this study. Propranolol was given after laryngoscopy and a CT scan with contrast of the trachea confirming the presence of a subglottic hemangioma. The starting dose of Propranolol was 0.5 mg/kg per day, given in 2 or 3 divided doses. Heart rate and blood glucose were monitored during the treatment. If no side effects occurred, the dose was increased to 1 mg/kg per day at the third day and to 2 mg/kg per day at the sixth day. Treatment was continued at home after 10 days of inpatient treatment and the children were reevaluated monthly.

RESULTSAfter 24 - 48 hours of treatment, all of the children had improvement in their airway obstruction which was confirmed by fibro-laryngoscopy. The diameter of the subglottic stenosis from the hemangioma decreased from 3.9 - 5.0 mm to 1.5 - 2.0 mm,and the color was also lighter than before. In 3 children with cutaneous hemangioma, there was also significant improvement in the cutaneous lesions after treatment, with the color becoming lighter. There were no significant ECG, blood pressure or blood biochemical changes during the treatment. Two of the children had hypoglycemia at the first dose, but improved after blood transfusion and changing their diet. In five children, the treatment was stopped after 6 to 11 months when the obstructive symptoms improved. None of the children in this group had any evidence of recurrence. In the 5 children who stopped treatment, the obstructing mass in the subglottis was less than 10% of the diameter.

CONCLUSIONOral propranolol is a safe and effective treatment for infantile subglottic hemangioma. It may be used as a first-line therapeutic modality.

Objective To dynamically observe the changes of cytokines of splenocytes in mice immunized with recombinant bifidobacteria bifidum (Bb)- Eg95-EgA31 vaccine of Echinococcus grauulosus (Eg). Methods Balb/c mice were vaccinated by 5× 108 colony forming unit(CFU) orally and 5 × 105 CFU intranasally, respectively.Mice were killed on week 0,2,4,6,8,10, 12,14,16, 18 and 20 after immunization, respectively, and spleens were separated for cell culture with the stimulation of EgAg, concanavalin A (ConA) or lipopolysaccharide (LPS). The splenocyte supernatants were collected to determine the levels of interferonγ(IFN-γ), interleukin(IL)-12, tumor necrosis factor α(TNF-o) and IL-l0 using enzyme linked immunosorbent assay(ELISA) with MRS as control. Results In the oral immunization group, the levels of IFN-γ, IL-12, TNF-α and IL-10 showed a significant increase from week 2 to week 8, week 2 to week 8, week 4 and week 6 to week 10 after vaccination, respectively, and reached the highest level on week 4, week 2, week 4 and week 6 after vaccination, respectively;in EgAg stimulation group, the levels of IFN-γ, IL-12, TNF-α and IL-10 were (700.0 ± 115.5), (45.0 ± 5.8), (350.0 ± 57.7), (112.5 ± 14.4)ng/L, respectively, compared with week 0[(35.0 ± 5.8), (12.5 ± 2.9), (190.0 ± 11.6), (25.0 ± 5.8)ng/L, P ＜0.05 or ＜ 0.01] and MRS control group[(37.5 ± 5.0),(13.8 ± 2.5), (195.0 ± 5.8), (27.5 ± 2.9)ng/L, P＜ 0.05or ＜ 0.01]. In the intranasal immunization group, the levels of IFN-γ, IL-12, TNF-α and IL-10 showed an obvious increase from week 2 to week 8, week 2 to week 8, week 2 to week 6 and week 6 to week 16 after vaccination,respectively, and reached the highest level on week 2, week 2, week 4 and week 8 after vaccination, respectively;in EgAg stimulation group, the levels of IFN-γ, IL-12, TNF-α and IL-10 were (700.0 ± 115.5), (55.0 ± 5.8),(275.0 ± 28.9), (140.0 ± 11.6)ng/L, compared with week 0[(35.0 ± 5.8), (12.5 ± 2.9), (190.0 ± 11.6), (25.0 ±5.8)ng/L, P ＜ 0.05 or ＜ 0.01] and MRS control group[(37.5 ± 5.0), (13.8 ± 2.5), (195.0 ± 5.8), (27.5 ± 2.9)ng/L, P ＜ 0.05 or ＜ 0.01]. The cytokine levels in the groups with EgAg, ConA or LPS stimulus were significantly higher than those in the corresponding splenocytes suspension groups(P ＜ 0.05 or ＜ 0.01) , and the cytokine levels in the groups with ConA or LPS stimulus were obviously higher than those in the corresponding groups with EgAg stimulation(P ＜ 0.05 or ＜ 0.01). Conclusion The mixed Th1 and Th2 type response can be induced in mice immunized with the recombinant Bb-Eg95-EgA31 vaccine of Echinococcus granulosus in the early stage of immunization(2 to 6weeks).

0.05).In addition,in different medication intervals and the same total dosage(200 mg),there was no difference in the number of patients who reached ASAS20,ASAS50 anti BASDAI50 in both groups.The changes of other parameters were not observed.Conclusion Two dosages and different medication interval of rhTNFR-Fc have similiar efficacy onset time and maintenee period.Mean- while,at the same total dosage,there is no signifieant difference in therapeutic effect in the two dosage groups. However,50 mg(1/7 d)regimen has better compliance than 25 mg(1/3 d).

Objective To investigate the role of CD4~+CD25~+ Treg cells on the pathogenesis of ankylos- ing spondylitis(AS), and to study the machanism of tumor necrosis factor(TNF)-?blocker on the treatment of AS by detecting the number of CD4~+D25~+ Treg cells before and after the treatment. Methods The diagno- sis of 10 AS patients was made based on the 1984 modified New York criteria. The patients received subcuta- neou injection of recombinant human tumor necrosis factor receptor-Fc fusion protein(rhTNFR-Fc)(etaner- cept)50 mg weekly for 8 weeks and 10 heathy subjects were enrolled for control. The mononuclear cells were isolated from peripheral blood in beth patients and controls. The number of CD4~+CD25~+ T cells and CD4~+ CD25~(high)T cells and the expression of CTLA-4. were detected by flow cytometry. Results The proportion of CD4~+CD25~+ T cells(24?19)% in total CD4~+ T lymphocytes of peripheral blood and CD4~+CD25~(high)T/CD4~+ T (6?6)% from AS patients before treated with rhTNFR-Fc was higher than that in healthy volunteers and AS patients after treatment(P

Objective To explore the relationship between the long-term presence of hypoxic tissue and astrocyte activation after cerebral infarction in rats. Methods Middle cerebral artery occlusion was performed in rats to induce permanent brain ischemia (PI group) or transient isehemia for 1.5 h followed by reperfusion (1.5 h IR group). Double immunofluorescence staining with EF5 and gliai fibrillary acidic protein (GFAP) antibodies was used to observe the hypoxic tissue and status of astrocyte activation, respectively. On days 1, 3, 7 and 14 after the operation, GFAP fluorescence intensity and the presence of hypoxic tissue in the ischemic cortex were observed. Results The hypoxic tissues were present from day 3 to day 14 after the operation in 1.5 h IR group, but disappeared after day 3 in PI group. GFAP fluorescence intensity in the hypoxic tissue was significantly higher than that in the surrounding tissues at all the observation time points (P<0.05). GFAP fluorescence intensity increased progressive in both groups with the lapse of time (P<0.05), reaching the peak level on day 7 followed then by gradual declination. On each of the time points for observation, GFAP fluorescence intensity in 1.5 h IR group was significantly higher than that in PI group (P<0.05). Conclusion Astrocyte activation is especially obvious in the hypoxic brain tissues after cerebral infarction, which is closely associated with the long-term existence of hypoxic tissues.
