ABSTRACT
OBJECTIVE To compare the clinical efficacy between adenoidectomy combined with auripuncture (AT+A) and adenoidectomy combined with tympanostomy tubes (AT+T) in children wiht otitis media with effusion. METHODS 92 cases of children with otitis media with effusion were selected from September 2010 to September 2014 in our hospital which was divided into AT+T group and AT+A group, depending on therapy methods.There were 48 in AT+T group and 44 in AT+A group. Retrospective analysis were made on a series of clinical data ,including the therapeutic effect, hearing threshold before and after treatment, infection rate and recurrence rate. RESULTS The hearing threshold has been significantly reduced within one year of follow-up after treatment,however,there was no significant difference (P>0.05). Total efficiency rate was 97.9% in AT+T group and 95.4% in AT+A group, no significant difference was found (P>0.05). The average middle ear fluid duration, infection and recurrence rate of children in AT+T group and AT+A group was (7.3±0.8) days, 6.3%, 4.2% and (11.7±0.4) days, 15.9%, 11.4% respectively, there was significant differences (P<0.05). CONCLUSION Both AT+T and AT +A have a good therapeutic effect for children with otitis media with effusion, which can significantly improve the hearing. Compared to AT+A, AT+T have a higher recovery rate,significantly reduce the recurrence and infection rate,and may be more suitable for clinical treatment of children with otitis media with effusion.
ABSTRACT
ObjectiveTo study the chemical constituents of Citrullus colocynthis.MethodsThe chemical constituents were isolated and purified by column chromatography on silica gel and Sephadex LH-20 and recrystallization as well.NMR spectra and physicochemical property were characterized for structural identification.ResultsEleven compounds wereisolatedandidentifiedasβ-sitosterol(1), α-spinasterol-3-O-β-D-glucopyranoside(2),α-spinasterone (3),bis (2-ethylhexyl) phthalate (4),p-hydroxybenzoic acid (5),6-C-p-methylbenzoylvitexin (6),dihydrocucurbitacin E (7),cucurbitacin E (8),dihydro-epi-iso-cucurbitacin D (9),dihydroisocucurbitacin B-25-acaetate (10),and cucurbitacin E 2-O-β-D-glucopyranoside (11).ConclusionCompound 6 is a novel compound.Compounds 1-5,7,9,and 10 are isolated from C.colocynthis for the first time.
ABSTRACT
Object To study the chemical constituents of our folk herb, Cucubalus baccifer L Methods The components were separated on Diaion HP 20 and silica gel column chromatography and the structures were identified by spectral evidence Results Six compounds from ethyl acetate extracts were elucidated as 6? methoxy piperidin 2 one (Ⅰ), pterolactam (Ⅱ), 5, 7, 4′ trihydroxyflavone (Ⅲ), 4 hydroxy 3 methoxybenzopropanyl acid (Ⅳ), 4 hydroxybenzoaldehyde (Ⅴ), and 4 hydroxybenzoic acid (Ⅵ) Conclusion Compound Ⅰ was a new naturally occurring compound and others were first isolated from this plant
