World Journal of Gastroenterology 2010年第26期16卷 3279-3286页

AIM: To compare the efficacy and safety of acellular dermal matrix (ADM) bioprosthetic material and endorectal advancement flap (ERAF) in treatment of complex anorectal fistula. METHODS: Ninety consecutive patients with complex anorectal fistulae admitted to Anorectal Surgical Department of First Affi liated Hospital, Xinjiang Medical University from March 2008 to July 2009, were enrolled in this study. Complex anorectal fistula was diagnosed following its clinical, radiographic, or endoscopic diagnostic criteria. Under spinal anesthesia, patients underwent identification and irrigation of the fistula tracts using hydrogen peroxide. ADM was securely sutured at the secondary opening to the primary opening using absorbable suture. Outcomes of ADM and ERAF closure werecompared in terms of success rate, fecal incontinence rate, anorectal deformity rate, postoperative pain time, closure time and life quality score. Success was defined as closure of all external openings, absence of drainage without further intervention, and absence of abscess formation. Follow-up examination was performed 2 d, 2, 4, 6, 12 wk, and 5 mo after surgery, respectively. RESULTS: No patient was lost to follow-up. The overall success rate was 82.22% (37/45) 5.7 mo after surgery. ADM dislodgement occured in 5 patients (11.11%), abscess formation was found in 1 patient, and fistula recurred in 2 patients. Of the 13 patients with recurrent fistula using ERAF, 5 (11.11%) received surgical drainage because of abscess formation. The success rate, postoperative pain time and closure time of ADM were significantly higher than those of ERAF (P < 0.05). However, no difference was observed in fecal incontinence rate and anorectal deformity rate after treatment with ADM and ERAF. CONCLUSION: Closure of fistula tract opening with ADM is an effective procedure for complex anorectal fistula. ADM should be considered a first line treatment for patients with complex anorectal fistula.

background: Fourth ventricle isolated Magendie's foramen primitive obstruction is rare. The etiology and the pathophysiology of the constitution of this obstruction in congenital cases remain elusive. We report a case of congenital obstruction of Magendie's foramen in an adult patient and discuss the embryogenic mechanism and our management of this rare *** presentation: A 20 years old female patient without any medical history was referred for headaches and vomiting. Emergency CT scan revealed major hydrocephalus subsequently she underwent a ventriculoperitoneal shunt as initial *** diagnosis of fourth ventricle obstruction was made 5 months later when the patient came back complaining of headaches, cerebellar signs and cystic dilatation of the fourth ventricle on CT scan and MRI. Fourth ventricle Magendie's foraminoplasty via classic posterior fossa surgery brings complete ***: Magendie's foramen obstruction is rare. The embryological development of the posterior fossa and its content could explain the primitive obstruction which can be managed by classic surgery in case of unavaibility of endoscopy.

英雄史诗的音乐语言是一个自足的语言体系,史诗音乐风格的构成中,江格尔奇表演时所组织运用的探索性语言、凝练性语言都是史诗所特有的语言表现形式。但仅仅关注史诗语言是不够的,还需要关注史诗表演中那些常用曲调,以及曲调构成不可缺少的音乐要素,对于史诗音乐表演来说也很关键。文章分析五首史诗常用曲调后认为,《江格尔》音乐曲调中的音程关系、同音反复、节奏模进、乐句重复等音乐程式手法对史诗音乐的整体风格产生着重要影响,其中江格尔奇在快速建构诗行的压力下,如何采用与史诗语言高度融合的音乐程式来建立新的史诗故事文本,将结合实例作出解答。

Two new monoprotonated products of macrocyclic polyamine 1,4,7 trimethyl 1,4,7 triazacyclononane(Me 3〔9〕aneN 3), (Me 3〔9〕aneN 3H)(SO 3CF 3) 1 (C 10 H 22 N 3O 3SF 3, M r =321.36) and (Me 3〔9〕aneN 3H)I 2 (C 9H 22 N 3I, M r =299.20) were obtained by the reactions of Me 3〔9〕aneN 3 and yttrium triflate or ytterbium diiodide as the unexpected products. The crystal structures of compounds 1 and 2 have been determined. Crystal 1 is orthorhombic, space group P2 12 12 1(#19), a =12.609(3), b=13.531(1), c=9.225(3) , V=1573.9(7)  3, Z=4, D c= 1.356 g/cm 3, μ =2.47 cm -1 , F (000)=680 and R=0.052, R w =0.052 for 807 unique reflections with I>2σ(I) . Crystal 2 belongs to the orthorhombic system with space group P2 12 12 1(#19), a=11.417(2), b=13.099(3), c=8.762(2) , V=1310.5(4)  3, Z=4, D c =1\^516 g/cm 3, μ =24.14 cm -1 , F (000)=600 and R=0.035, R w =0.042 for 1427 unique reflections with I>3σ(I) . The two structures contain the same cyclic framework in which the acid proton is bonded to an amine nitrogen. This proton exhibits strong intramolecular hydrogen bonds with the other two nitrogen atoms. The methyl groups are directed away from the ring cavity. The bond distance between acid proton and an amine nitrogen in compound 2 is extremely short. The bond angles for 1 and 2 also exhibit obvious diversity inside of triazacyclononae.
