恶性青光眼手术治疗失败的探讨

目的：探讨恶性青光眼手术治疗失败的原因。分析2002年以来常见的恶性青光眼5例。手术方式。术后视力。眼压等情况。结果：5例患者都是行抗青光眼术（虹膜艰切或滤过性手术）后，分别观察两年、一年、及半年后虹膜形成新生血管，眼压持续升高。对药物治疗及再次手术治疗效果不佳。严重影响了视力。结论：单纯虹膜根切，滤联切除术对早期青光跟病情缓解有效．但弥漫性房角关闭，周边虹膜前粘连的顽固病例，虹膜嵌顿于滤过道内白。虹膜囊肿阻塞周边切口，虹膜前粘连阻塞滤过道内口。滤过道为瘢痕组织阻塞，滤过道内口为残留虹膜阻塞等原因，导致手术治疗失败!

黄芪（Astragalus）

又名 Beg kei, Bei Qi, Buck Qi, Huang Qi, Huang qi, Hwanggi, Membranous Milk Vetch, Milk Vetch, Mongolian Milk, Ogio 植物名Astragalus membranaceus ; A. mongholicus.活性成分与药理作用黄芪的药用部位是根，含有40种以上皂苷(如黄芪苷)，此外还有黄酮类、多糖类、微量矿物质、氨基酸和香豆素类。黄芪是一种抗氧剂，抑制自由基的产生，增加超氧化物歧化酶，减少脂质过氧化。黄芪具增强免疫系统、肝和心血管系统的作用，通过干扰素的增效作用改善免疫应答。     

DETECTION OF HIGH-PATHOGENICITY ISLAND-HARBORING ESCHERICHIA COLI ISOLATED FROM CHILDREN WITH DIARRHEA DISEASE IN CHINA

[Objective] To investigate the etiologicla status of etiologica status of high-pathogenicity island-harboring Escherichia coil(HPIEC) in dianhea disease among children. [Method] Diarrheagenic Esoherichia coli was isolated and identified from the stool specimens of 1032 children with dianhea diseases by culturing, serotyping, Polymerase chain reaction amplification (PCR), the High-pathogenicity island-harboring Esoherichia coli (HPIEC) was identified by PCR and in situ hybridization. [Results] A total of 652 strains of E.coli isolated from 1032 stool specimens and confirmed by serotyping, PCR and colony hybridization out of which 225 were identified as diarrheagenic E.coil,including 20 EPEC,81 ETEC, 47 SLTEC, 74 ESIEC, and 3 EIEC strains. 112(17.2%)irp2 virulent gene positive E.coli (HPIEC) were detected from the 652 strains, out of which 24 were from the 74 ESIEC strains and 17 from the 47 SLTEC strains. The typical clinical symptoms of children with diarrhea disease caused by HPI- harboring E.coli included anorexia(87.5%) ,abdominal pain(58.0%), diarrhea (75.9%,Over six episoders, mostly of mucous stool a day), and fever(50.9%). [Conclusion] High-pathogenicity island-harboring E.coli is one of the important pathogens of diarrhea diseases in children.     

外伤性脱位前牙治疗的临床分析

目的:分析外伤性脱位前牙临床治疗的效果。方法:对71颗不同类型的脱位前牙治疗方法和治疗结果进行综合分析。结果:脱位牙的根管治疗率为70.4%,其中部分脱位牙68.0%,完全脱位牙76.2%;脱位牙的牙根吸收率为45.1%,其中根管治疗前39.4%,根管治疗后5.7%。结论:根管治疗是脱位牙治疗的重要手段,早期根管治疗可预防或减少脱位牙牙根的吸收。

人血对三种根管充填材料密封性影响的实验研究

本文以2％亚甲基蓝染料在36个离体牙上分别用三种本院常用根管充填材料根充后,在干燥、潮湿及人血浸泡三种状态下进行色素微渗漏试验,从而证实人血及潮湿环境能降低某些根管充填材料在根管中的密封性,由此而导致某些根管治疗术的失敗。
