计算机辅助导航系统和个体化三维钛网在陈旧性眶颧骨折治疗中的应用

目的:研究计算机辅助导航系统结合个体化三维钛网在复合性眼眶骨折治疗中的应用,并与传统手术方法进行比较,评价其治疗效果。方法:2008年10月-2010年12月在上海交通大学医学院附属第九人民医院口腔颌面外科和眼科联合治疗的陈旧性单侧眶颧骨折伴眼球内陷畸形病例64例,其中25例采用计算机辅助手术治疗以提高颧骨复位的准确性,术前眼球内陷平均5.71mm;39例采用传统方法治疗,术前眼球内陷平均4.96mm。眶重建中,35例采用钛网,12例采用聚乙烯聚合物(Medpor),5例采用羟基磷灰石板(HA),12例采用钛网+Medpor或HA。手术前后进行眼眶CT扫描、冠状和三维骨重建,术后评价颧骨复位和眼球内陷矫正效果。结果:计算机辅助治疗术后颧骨复位的满意率为92%,眼球突度满意率(≤2mm)为82%,轻度眼球内陷率(≤3mm)为17%。传统手术颧骨复位满意率为74%,眼球突度满意率为74%,轻度眼球内陷率(≤3mm)为19%,中度眼球内陷率(≤4mm)为6%。眼球突度满意率,单纯使用钛网为74%,联合材料为83%,Medpor为67%,HA为20%。结论:计算机辅助手术可提高陈旧性眶颧骨折伴眼球内陷畸形的治疗效果;钛网联合Medpor是治疗严重眼球内陷畸形的良好方法。     

神经发育水平与儿童口吃:一对异卵双生子的个案研究

本研究报告了一对异卵双生子的个案。其中一个存在口吃症状,而另一个没有。研究者通过对这对双生子在言语能力发展水平和神经心理发育水平的检查,发现口吃与儿童的神经心理发育超前没有关系。相反,口吃的出现与神经心理发育滞后密切关联。这一发现为揭示口吃发生机制提供了关键证据,并将促进有关口吃儿童神经和心理发育的进一步研究。1对象与方法1.1对象个案A和B为双生子,男性,北方人,汉族,年龄为41.5个月。父母都是北方人,讲标准普通     

342例女性假两性畸形的荟萃分析

 目的总结1994-2009年国内外公开发表的以及我院2000年至今诊治的女性假两性畸形(FPH)的病例,探讨其临床特点。方法以"女性假两性畸形"的中英文单词作为检索词,检索1994-2009年国内外公开发表的文献,并结合我院诊治的10例患者,进行荟萃分析。结果共检索到332例诊断明确的病例,加上我院的10例,共有342例入选病例。出生时即就诊的患者仅有27例,其他病例就诊年龄为1个月59岁不等,315例患者就诊时的中位年龄为29.54岁。病因以先天性肾上腺增生为主(70.47%)。临床表现主要为骨骼生长较快(95.52%)、阴蒂肥大(84.14%)以及不同程度的男性化(77.24%)。在治疗方式上以药物和手术的联合治疗为主。首次接受治疗的时间及治疗方法在预后方面起着至关重要的作用。结论女性假两性畸形并非罕见疾病,我们应提高对该病的认识,提早患者接受治疗的时间,坚持终身用药,以改善其预后。     

解脲脲原体生物被膜形成与耐药性的相关性研究

目的 研究解脲脲原体(Ureaplasma urealyticum,Uu)标准株及临床分离株体外形成生物被膜的能力及游离状态与形成生物被膜后药物敏感性的差异.方法 对Uu标准株3、8血清型(Uu3、Uu8)及从女性患者宫颈中分离鉴定的21株Uu临床株进行体外培养后,扫描电镜、激光共聚焦显微镜鉴定生物被膜形成,并在生物被膜形成前后进行约敏测定(四环素、红霉素、环丙沙星).配对秩和检验及x2检验分别比较Uu游离状态及形成生物被膜后最低抑菌浓度间及耐药率间的差异.结果 Uu3、Uu8及21株Uu临床株均具有体外形成生物被膜的能力.Uu形成牛物被膜后对四环素、红霉素及环丙沙星的最低抑菌浓度较游离状态明显增高(P<0.001).Uu形成生物被膜后对红霉素及环丙沙星的耐药率增高具有统计学意义(P值分别为<0.001及0.035),但对四环素的耐药率增高无统计学意义(P=0.293).结论 Uu标准株及临床株均具有体外形成生物被膜的能力,Uu形成生物被膜后对抗菌素的抵抗力增加,出现了多重耐药现象.     

Uncommon flexural presentation of Darier disease

BACKGROUND: Darier disease is an autosomal dominant skin disorder characterized by keratotic papules, focal loss of adhesion, and abnormal keratinization. Several clinical variants of Darier disease have been described. Predominant flexural distribution of lesions in Darier disease is uncommon. OBJECTIVE: We report a sporadic case of Darier disease in which the lesions were strictly localized to the flexures. We also briefly review the differential diagnoses of such atypical localization. METHODS AND RESULTS: A 26-year-old female presented with erythematous and hyperpigmented papular lesions localized to flexures for 4 months. The skin of the other areas, hairs, nails, and mucosa was normal. Histopathologic examination revealed suprabasal acantholysis along with dyskeratotic keratinocytes, consistent with Darier disease. CONCLUSION: Physicians should be aware of such atypical localizations and should consider the diagnosis of flexural Darier disease along with more common clinical conditions with flexural localization, such as Hailey-Hailey disease and occasionally Grover disease.     

代谢组学在子痫前期预测及诊断中的应用

通过不同代谢组学技术检测子痫前期患者血清、尿液及胎盘组织中差异代谢产物表达,提出联合多种代谢产物能够显著提高预测及诊断子痫前期的敏感性及特异性,可为子痫前期尤其是早发子痫前期的预测及诊断提供良好的生物学标志物。     

Hypocholesterolemic activity of indigenous probiotic isolate Saccharomyces cerevisiae ARDMC1 in a rat model

The aim of this study was to investigate probiotic attributes of Saccharomyces cerevisiae ARDMC1 isolated from traditional rice beer starter cake and its hypocholesterolemic effects on Wistar rats fed a high-cholesterol diet. The indigenous isolate ARDMC1 showed potential probiotic characteristics such as tolerance to simulated gastrointestinal stress conditions, autoaggregation properties, and adhesion to intestinal epithelium Caco-2 cell line. In addition, ARDMC1 isolate exhibited in vitro cholesterol assimilation properties in media supplemented with cholesterol. Furthermore, administration of probiotic isolate to rats fed a hypercholesterolemic diet resulted in significant reduction of serum total cholesterol, low-density lipoprotein cholesterol, and triglyceride at the end of 42 days. The present study envisages ARDMC1 as a promising starter culture for the preparation of functional foods with properties to combat cardiovascular diseases.
