<正>Objective To study the value of preoperative detrusor contractility to the outcome assessment of prostatectomy for benign prostatic hyperplasia ( BPH) . Methods A total of 109 patients with BPH were analyzed. Their ages ranged from 62 to 83 years with a mean of 71     

成人肾恶性横纹肌样瘤15例临床病理及免疫表型分析

目的：探讨成人肾恶性横纹肌样瘤（MRTK）的病理组织学,分子免疫表型的特点及临床意义.方法：对我院1983～2009年收治15例肾脏恶性横纹肌样瘤的石蜡组织切片运用SP法进行免疫组化染色,检测Vi-mentin、Myoglobin、Desmin、α-SMA、EMA、NSE、S-100的表达,并结合临床病理特征进行分析.结果：组织学上瘤细胞胞界清楚.胞浆丰富具有嗜酸性颗粒、常见大的嗜酸性包涵体,呈圆形或椭圆形,将细胞核挤向一侧.核膜明显而核仁突出,核分裂多见.经SP染色后,Vimentin均警阳性或强阳性表达,EMA、NSE和S-100均有不同程度的阳性表达,α-SMA有2例呈阳性表达,而Myoglobin、Desmin均呈阴性表达.结论：成人MRTK是一种表达多种免疫抗原,独立的可多向分化的肾恶性肿瘤,Vimentin和Myoglobin、Desmin、α-SMA有助于MRTK的诊断和鉴别诊断.     

Epidemiology of dengue and dengue hemorrhagic fever in a cohort of adults living in Bandung, West Java, Indonesia

A prospective study of dengue fever (DF) and dengue hemorrhagic fever (DHF) was conducted in a cohort of adult volunteers from two textile factories located in West Java, Indonesia. Volunteers in the cohort were bled every three months and were actively followed for the occurrence of dengue (DEN) disease. The first two years of the study showed an incidence of symptomatic DEN disease of 18 cases per 1,000 person-years and an estimated asymptomatic/ mild infection rate of 56 cases per 1,000 person-years in areas of high disease transmission. In areas where no symptomatic cases were detected, the incidence of asymptomatic or mild infection was 8 cases per 1,000 person-years. Dengue-2 virus was the predominant serotype identified, but all four serotypes were detected among the cohort. Four cases of DHF and one case of dengue shock syndrome (DSS) were identified. Three of the four DHF cases were due to DEN-3 virus. The one DSS case occurred in the setting of a prior DEN-2 virus infection, followed by a secondary infection with DEN-1 virus. To our knowledge, this is the first report of a longitudinal cohort study of naturally acquired DF and DHF in adults.     

NNMT在肾透明细胞癌的表达及对肾癌细胞侵袭能力的影响

目的:研究NNMT在肾透明细胞癌中的表达情况及对肾癌细胞侵袭能力的影响。方法:采用RT-PCR和Western blot方法检测正常肾小管上皮细胞株HKC、肾癌细胞株786-O及30例肾透明细胞癌组织、相应癌旁组织中NNMT的mRNA和蛋白的表达水平,并分析NNMT的mRNA水平与临床病理参数的关系。化学合成针对NNMT特异的siRNA序列,应用脂质体Lipofectamine 2000将其转染进786-O细胞中,利用RT-PCR和Western blot法检测NNMT在786-O细胞中的表达水平,用Transwell小室法检测肾癌细胞786-O侵袭能力的变化。结果:NNMT在肾癌细胞786-O中的mRNA和蛋白表达水平显著高于正常肾小管上皮细胞株HKC(P<0.001);肾透明细胞癌组织和对应的癌旁组织中NNMT的mRNA相对表达量分别为(1.582±0.2145)、(0.1269±0.04279),两组比较P<0.001。NNMT的mRNA水平与肿瘤大小、临床分期有关(P<0.05);Tran-swell法检测结果显示降低NNMT的表达后786-O细胞的侵袭能力明显下降。结论:NNMT在肾透明细胞癌组织和细胞中表达升高,可能在肾癌发生、发展过程中发挥重要作用。     

Group A rotavirus-associated diarrhea in children seeking treatment in Indonesia

BACKGROUND: Globally, group A rotavirus causes significant morbidity and mortality among children. Limited data exist on the epidemiology of rotavirus disease among Indonesian children. OBJECTIVES: We describe the epidemiology of rotavirus-associated diarrhea among Indonesian children <6 years of age, including clinical symptoms and genotypes. STUDY DESIGN: We conducted a hospital-based, case series study at four referral hospitals between February 2004 and February 2005 among children with diarrhea. Rotavirus positivity was defined by a positive result from either EIA or RT-PCR. A semi-nested RT-PCR was used to determine specific rotavirus genotypes. RESULTS: 1660 stools were tested for pathogens. The overall rotavirus prevalence was 45.5%. Children with rotavirus-associated diarrhea were significantly younger (p<0.0001) and more likely to be hospitalized (81.3% versus 72.2%; p<0.0001). Symptoms associated with rotavirus included, vomiting, fever, nausea, fatigue and dehydration, while bloody stool was significantly less common with rotavirus-associated diarrhea. CONCLUSION: Rotavirus was an important contributor of morbidity to our study sample. Rotavirus genotyping demonstrated a temporal shift from G1-G4 to G9, but this was highly associated with the P[8] gene, suggesting that a multivalent rotavirus vaccine, incorporating G9 P[8] antigen, may reduce the burden of diarrheal illnesses among Indonesian children.
