Intraepithelial neoplasia, human papilloma virus infection and argyrophilic nucleoprotein in cervical epithelium

A silver colloid technique was applied to 50 colposcopic biopsies of cervix. These comprised nine cases of wart virus infection of the cervix, 11 cases of cervical intraepithelial neoplasia (CIN) I, nine cases of CIN II, eight cases of CIN III, seven normal biopsies and six cases showing only incomplete squamous metaplasia. The mean numbers of argyrophilic nucleolar organizer regions (AgNORS) increased from CIN I to CIN III. Statistically significant differences for AgNORs were found in comparisons between CIN III, normal basal cells, human papilloma virus-infected basal cells and incomplete squamous metaplasia, and in comparisons between normal basal cells and human papilloma virus-infected basal cells. CIN III could be distinguished from incomplete squamous metaplasia and from basal cells and from human papilloma virus-infected basal cells. The latter could be distinguished from normal basal cells on the basis of their AgNORs. It is suggested that this simple technique is diagnostically useful and has considerable clinicopathological potential in cervical pathology and cytology.     

宫颈细胞学和电子阴道镜在宫颈病变早期诊断中的应用研究

目的进一步评价细胞学和电子阴道镜在宫颈病变的早期诊断中的价值.方法回顾性分析431例宫颈涂片和阴道镜检的结果,与活检组织病理学的结果进行对比研究.结果 431例中检出宫颈上皮内瘤变(CIN)Ⅰ 39例、CIN Ⅱ 36例、CIN Ⅲ 32例、宫颈鳞癌11例和宫颈湿疣27例,其余286例为慢性宫颈炎.宫颈涂片检出了93.5%宫颈病变,阴道镜检出了95.9%宫颈病变,细胞学与阴道镜下活检联合应用无漏诊.结论细胞学与阴道镜下活检联合应用能提高宫颈病变的检出率,阴道镜检查能明显提高宫颈湿疣的检出率.     

70例宫颈上皮内瘤样病变宫颈环形电切术后情况分析

对70例要求保留生育功能的宫颈上皮内瘤样病变（CIN）患者进行宫颈环形电切术（LEEP），并对其疗效、病灶持续存在和复发等情况进行分析。结果：70例中，首次LEEP治愈65例（92．86％），2例（2．86％）病变持续存在，2例（2．86％）术后复发，1例LEEP后病检为宫颈微小浸润癌而行根治术。5例（7．14％）出现术中、术后并发症。认为LEEP治疗CIN安全有效，但术后随访非常重要。     

Serologic response to human papillomavirus 16 among Australian women with high-grade cervical intraepithelial neoplasia

This study evaluated the detection of human papillomavirus (HPV) 16 antibody in HPV 16-associated cervical intraepithelial neoplasia (CIN) in Australian women. Seroreactivity to HPV 16 L1 virus-like particles was assessed in patients with CIN 2 (n= 169) and CIN 3 (n= 229) lesions previously tested for the presence of HPV DNA. Seropositivity was significantly commoner in women with HPV 16 DNA-positive lesions (98/184) than in women with no HPV DNA in the lesion (15/47) or with HPV of types other than 16 in the lesion (43/167) (P= 0.0004). In addition, seropositivity was observed in 33% (55/169) of women with CIN 2 and 46% (106/229) of women with CIN 3, in keeping with the lower fraction of CIN 2 (57/169) than CIN 3 (127/229) biopsies positive for HPV 16 DNA. HPV 16 seropositivity is most common in women with HPV 16-associated CIN, but many patients with HPV-associated CIN 3 are seronegative, and HPV 16 seropositivity is common in women with CIN associated with other HPV types. Overall, HPV 16 serology is a poor predictor of presence of HPV 16-associated CIN 3 in patient population studied.

多层螺旋CT和经胸二维超声心动图检查

目的 探讨多层螺旋CT(MSCT)及联合经胸二维超声心动图(TTE)检查在先天性心脏病诊断中的意义。方法收集广东省心血管病研究所自2002年9月至2003年12月间86例儿童先天性心脏病病例，全部患儿接受了MSCT和TTE检查，12例接受心导管检查，其中69例进行了外科手术，将术前MSCT、TTE和心导管检查结果分别与手术诊断进行比较。结果 69例患儿共计有129处畸形，TTE正确诊断116处(89.9%)，MSCT正确诊断112处畸形(86.8%)，两者联合正确诊断127处畸形(98.4%)，12例心导管检查未能提供更有价值的资料。结论 MSCT对先天性心脏病诊断具有较高的价值，尤其是联合TTE可取代部分心导管检查为外科手术提供正确和充分的术前诊断。对于年龄小或重症不耐受心导管检查的患儿具有更大的意义。 Abstract Objective To evaluate the effectiveness of multislice computed tomography (MSCT) in diagnosis of congenital heart diseases in children.Methods 86 patients were involved.69 had been performed operations.The preoperative results of transthoracic two dimensional echocardiography (TTE),MSCT and angiocardiography were compared with those of surgery.Results Of the totally 129 malformations,TTE had correctly revealed 116 (90%),MSCT 112(86.8%),and both combined had correct diagnosis for 127(98.4%).Angiocardiography in 12 patients had not provided further information. Conclusion MSCT is a valuable additional diagnosis tool in congenital heart diseases,especially when combined with TTE.They might take place some of the angiocardiography before surgery. Key words Multislice computed tomography;Transthoracic two dimensional echocardiography;Congenital heart disease

The association between myeloperoxidase (MPO) polymorphism and the risk of cervical cancer is inconclusive. We performed a meta-analysis to clarify if a correlation exists between MPO polymorphism and the risk for developing cervical cancer.

冠状动脉介入术导致对比剂肾病危险因素分析

目的探讨冠状动脉介入术患者对比剂肾病的危险因素。方法收集我院2008年1月~2009年12月期间住院的172例接受冠状动脉介入术患者的临床资料,比较对比剂使用剂量,测定介入治疗前后血清肌酐,分析发生对比剂肾病危险因素。结果 172例患者发生对比剂肾病32例,发生率18.61%(32/172),肾小球滤过率>60 mL/min患者发生对比剂肾病21例(13%),肾小球滤过率<60 mL/min患者发生对比剂肾病19例(40%)(P<0.001),年龄≥75岁、3支病变、左心室射血分数<40%、血清肌酐>133μmol/L及对比剂剂量>300 mL与对比剂肾病相关(P<0.001)。糖尿病或高血压合并肾功能不全对比剂肾病发病率高于单纯糖尿病或高血压患者(P<0.01)。结论介入治疗术前肾功能受损及其损害程度是术后出现对比剂肾病的最主要危险因素,肾功能不全、年龄≥75岁、多支冠状动脉病变、左心室射血分数<40%、对比剂剂量>300 mL均为对比剂肾病的独立危险因素。糖尿病或高血压病合并肾功能不全可以增加对比剂肾病的临床风险。
