A clinico-pathological study of postcoital bleeding

Methods. To undertake a clinical study of postcoital bleeding (PCB) in a district general hospital we retrospectively reviewed the records of 248 patients referred to the gynaecology department over a 5-year period. Results. 63% were in the 21–40-year age group and 80% were multiparous. Seventy per cent were referred to the gynaecology out patients' clinic and 28% to the colposcopy clinic. Associated symptoms included menstrual abnormalities (39%) and dyspareunia (13%). Twenty per cent had benign polyps, including endometrial polyps and 25% had cervical ectropion. Cervical intraepithelial neoplasia was detected in 6.8% of cases. There was no case of invasive cancer of the lower genital tract. Conclusions. This is the first report of associated endometrial polyps contributing to PCB. We conclude that CIN may not always be asymptomatic and the incidence of cervical or endometrial cancer is low in women with PCB.     

可降解材料纤维蛋白胶介导血管内皮细胞生长因子对心肌梗死组织血管再生的影响

背景：血管内皮细胞生长因子（vascular endothelial growth factor,VEGF）可促进梗死心肌血管再生,但经系统性静脉灌注来传递VEGF是无效的,反复直接心肌注射会损伤正常心肌结构。目的：验证通过可降解材料纤维蛋白胶将VEGF移植到心肌梗死及缺血区域促进血管再生的可行性,并观察大鼠心功能的变化。设计、时间及地点：随机对照动物实验,于2007-01/2008-04在新疆医科大学第一附属医院冠心病VIP实验室完成。材料：树脂色谱法纯化获得重组蛋白VEGF121,与纤维蛋白胶结合得到VEGF纤维蛋白胶。9周龄雄性SD大鼠28只,其中13只节扎冠状动脉左前降支制备心肌梗死模型为心肌梗死组,其余15只仅打开心包,不节扎左前降支者为为非心肌梗死组。方法：心肌梗死组梗死即刻将空白或VEGF纤维蛋白胶移植到梗死区域,附着在梗死和缺血区;非心肌梗死组将空白或VEGF纤维蛋白胶附在相应的左室前壁,另有3只不处理做为对照。主要观察指标：移植4周后经心脏超声行心功能检测,然后麻醉处死大鼠,取出心脏行免疫组化及血管测量分析。结果：移植VEGF胶后,非心肌梗死和心肌梗死组大鼠的毛细血管密度显著高于空白胶组（P〈0.001）;心肌梗死组梗死附近缺血区毛细血管密度显著高于间隔区（P〈0.01）。移植VEGF胶后,大鼠心功能有改善的趋势,但差异无显著性意义（P=0.2482）,结论：通过可降解材料移植VEGF可使大鼠非心肌梗死区和心肌梗死心肌区的毛细血管明显增生;将纤维蛋白胶作为传递血管再生因子到心肌的介质是可行的。     

Focal Dermal Hypoplasia Due to a Novel Mutation in a Boy with Klinefelter Syndrome

A boy was born with multiple anomalies, including right hemifacial microsomia, eye abnormalities, syndactyly, right hand ectrodactyly, hypoplastic nails, omphalocele, bladder exstrophy, renal dilatation, and splayed symphysis pubis. The skin was also abnormal, with atrophic skin plaques and areas of telangiectasia along the lines of Blaschko. The karyotype was 47,XXY (Klinefelter syndrome). He was found to have a heterozygous mutation in the PORCN gene. He exhibited the classical features of focal dermal hypoplasia. Fewer than 15% of reported cases are male when it is thought to be due to postzygotic mutation and thus mosaic. This is the first reported boy to have heterozygous mutation for Goltz syndrome who survived due to the extra X chromosome.

摘要：健康细胞移植到心肌损伤部位是当前关注的热点。组织工程的三维支架材料可替代丢失和损伤的细胞外基质，对自我或移植细胞提供支持，避免或减少梗死区移植细胞被冲洗掉或死亡，并通过微环境线索获得组织的再生和修复，从而预防和改善心功能。就生物活性可降解材料的设计、修饰及目前常用的类型的研究现状做一综述，为可降解材料的应用研究提供理论依据。     

Lipoprotein(a): an independent risk factor for ischemic heart disease that is dependent on triglycerides in subjects with type 2 diabetes mellitus

   

Lipoprotein(a) is an independent risk factor for Ischaemic Heart Disease (IHD) in the general population. There are conflicting reports in the extent of its association with IHD among subjects with Type 2 diabetes mellitus (T2DM).     

Diagnostic challenges of an unusually large schwannoma of the mandible: Report of a case

Schwannomas are slow-growing, benign neoplasms arising from the Schwann cells and are commonly reported as peripheral tumors in the head and neck region. Central intramandibular schwannomas are extremely rare lesions. We report a case of intramandibular schwannoma in a 70?year old male patient. Panoramic radiography revealed a large, multilocular radiolucent lesion with distinct borders involving the right mandibular body and ramus. A complete excision was achieved by removing the tumor followed by reconstruction of the mandible. The clinical, radiological, and histopathological features are discussed within the context of this case.     

Prevalence and clinical significance of pleural effusion in patients with acute pulmonary embolism: a retrospective study

BackgroundPleural effusion is observed in a subset of patients with acute pulmonary embolism (APE) and may be linked to clinical outcome, but findings from previous studies have been inconsistent. This study aimed to investigate the prevalence and clinical significance of pleural effusion in Chinese patients with APE.MethodsClinical data from hospitalized patients with APE were retrospectively collected and the prevalence of pleural effusion was determined. The relationship between the presence of pleural effusion and clinical outcome of APE was analyzed by Cox proportional hazards regression and Kaplan-Meier survival analysis.ResultsThe study enrolled 635 patients with APE. The prevalence of pleural effusion was 57.01% (362/635). Patients with pleural effusion had significantly higher in-hospital mortality (9.9% vs. 4.8%, P<0.05) and longer length of hospital stay (LOS) (19.99 vs. 15.31 days, P<0.05) than whose without pleural effusion. However, pleural effusion was not an independent risk factor for in-hospital mortality in patients with APE by multivariate Cox proportional hazards regression analysis [hazard ratio (HR) =1.70, 95% confidence interval (CI): 0.73–3.92, P=0.216] and Kaplan–Meier survival analysis (P=0.174).ConclusionsPleural effusion is a frequent occurrence in patients with APE and therefore merits greater attention from clinicians; however, it is not an independent risk factor for in-hospital mortality.
