Bladder outflow obstruction masquerading as pelviureteric junction (PUJ) obstruction

We report a case of bladder outflow obstruction presenting with upper tract dilatation mistaken initially as pelviureteric junction (PUJ) obstruction. The lower tract obstruction ought to be dealt with first before upper tract obstruction is assessed because the renal pelvic pressure is significantly affected by vesical filling and high bladder pressure.

三黄软膏皮肤用药毒性实验研究

为观察三黄软膏药物外用的安全性 ,进行了动物完整皮肤及破损皮肤长期接触三黄软膏 ,经皮肤渗透对局部及全身产生的毒性和反应的恢复程度 ,用三黄软膏 2g·kg-1、10g·kg-1剂量 (分别相当于 6 0kg人临床用量的 10、5 0倍 )连续对家用兔外用给药4周及停药恢复性观察 2周。结果表明给药期动物的皮肤状况、全身症状、行为活动、摄食、粪便性状、体重增长、血液学均未见明显的毒性反应 ,而高剂量组动物血液生化指标AST、ALT明显增高 ,病理组织学检查时肝水肿明显 ,可见有一定的毒性反应 ;停药期动物的血液生化指标AST、ALT肝组织病理组织学检查恢复正常 ,其他各项指标均未见明显的毒性反应 ,可见该毒性反应是可逆恢复的。表明三黄软膏在临床用药范围内连续使用是比较安全的。

Lamivudine for the prevention of hepatitis B virus reactivation in hepatitis B s-antigen seropositive cancer patients undergoing cytotoxic chemotherapy.

PURPOSE: For cancer patients receiving cytotoxic chemotherapy, hepatitis B virus (HBV) reactivation is a well described complication resulting in varying degrees of liver damage. The objectives of this study were to assess the efficacy of the antiviral agent lamivudine in reducing the incidence of HBV reactivation and diminishing morbidity and mortality of cancer patients with chronic HBV infection during chemotherapy. PATIENTS AND METHODS: Two groups were compared in this nonrandomized study. The prophylactic lamivudine group consisted of 65 patients in a phase II study who were treated with lamivudine before and until 8 weeks after discontinuing chemotherapy. The historical controls consisted of 193 consecutive patients who underwent chemotherapy without prophylactic lamivudine. Significant prognosticators for the development of HBV reactivation were determined based on data from the controls. Potential confounding factors were identified between the two groups. The outcomes were compared. RESULTS: In the controls, lymphoma and anthracycline usage were factors identified to be associated with reactivation. The two groups were comparable in most baseline characteristics, although in the prophylactic lamivudine group, there were significantly more patients with lymphoma and receiving anthracyclines. In the prophylactic lamivudine group, there was significantly less HBV reactivation (4.6% v 24.4% in the controls; P <.001), fewer incidences of hepatitis (17.5% v 44.6%; P <.0001) that were less severe (4.8% v 18.7%; P =.0005), and less disruption of chemotherapy (15.4% v 34.6%; P =.0029). The reduction in overall mortality was not statistically different. CONCLUSION: Prophylactic lamivudine significantly reduced the incidence of HBV reactivation and the overall morbidity of cancer patients undergoing chemotherapy.     

非小细胞肺癌中细胞周期蛋白D1与E的作用及相互关系

目的 :研究细胞周期蛋白D1与E在非小细胞肺癌 (NSCLC)发生、发展中的作用及相互关系。方法 :免疫组化方法检测 87例NSCLC肿瘤组织中细胞周期蛋白D1、E的表达及PCNA估计增殖指数 (PI) ,并将上述结果与临床病理及预后资料进行对比分析。结果 :87例NSCLC中细胞周期蛋白D1、E阳性率分别为 4 4 .8% (39/87)、4 8.3% (42 /87) ,细胞周期蛋白D1阳性组的PI值显著高于阴性组 (P〈0 .0 5 ) ,细胞周期蛋白E阳性组PI值与阴性组无显著差异 (P〉0 .0 5 ) ;细胞周期蛋白D1阳性组肿瘤直径、淋巴结转移率和生存率均与阴性组有显著差异(P〈0 .0 1、〈0 .0 5、〈0 .0 1) ,细胞周期蛋白E阳性组淋巴结转移率、临床分期和生存率均与阴性组有显著差异 (P〈0 .0 5、〈0 .0 5、〈0 .0 1) ;细胞周期蛋白D1阳性组中细胞周期蛋白E的阳性率显著高于其阴性组 (P〈0 .0 5 ) ;细胞周期蛋白D1与细胞周期蛋白E双阳性组的PI值、肿瘤直径、淋巴结转移率显著高于非双阳性组 (P值均〈0 .0 5 ) ,生存率显著低于非双阳性组 (P〈0 .0 1)。结论 :细胞周期蛋白D1、细胞周期蛋白E均参与NSCLC的发生、发展 ,并影响其预后 ,但两者在其中所起作用不同 :细胞周期蛋白D1是调节NSCLC增殖的主要因素 ,细胞周期蛋白E主要与NSCLC进展有关 ;细胞周期蛋白D1可促
