A diagnostic algorithm for male genital oedema

Male genital oedema can be defined as swelling or the appearance of swelling of the scrotum and/or the penile shaft and prepuce. Despite the various causes of genital oedema reported in the published work, a concise approach to the evaluation and management has not been sufficiently addressed.     

肾盂输尿管癌细胞增殖与凋亡的相关性

目的探讨Ki-67和凋亡（Apoptosis）在肾盂输尿管癌中的表达及其与肿瘤细胞分级、病理分期及预后的关系。方法采用SABC法和TUNEL法对34例肾盂输尿管癌行Ki-67和凋亡检测。结果Ki-67和凋亡在肿瘤细胞分级间存在显著差异,Ki-67index：G2与G1比较P〈0.05,G3与G2比较P〈0.05,G3与G1比较P〈0.01;Apoptosis index：G2与G1比较P〈0.05,G3与G2比较P〈0.05,G3与G1比较P〈0.01。Ki-67和凋亡在肿瘤病理分期的T3与T1及T2与T1之间有显著差异,T2与T1比较P〈0.05,T3与T1比较P〈0.01,但T3与T2比较P〉0.05;Ki-67index以20%为界分为二组,Apoptosis index以3%为界分为二组,组间生存率有显著差异（P〈0.05）。Ki-67在肾盂输尿管癌中的表达与凋亡一致。结论肾盂输尿管癌细胞增殖与凋亡密切相关;凋亡可作为临床判断肾盂输尿管癌恶性程度、病理分期、细胞分级以及预后的一种客观量化指标。     

Picotamide inhibition of excess in vitro thromboxane B2 release by colorectal mucosa in inflammatory bowel disease.

BACKGROUND: Inflammatory bowel disease is associated with increased mucosal release of eicosanoids. Among these, thromboxane A2 has been proposed as a possible inflammatory mediator; its suppression may be a useful therapeutic option. METHODS: Using a tissue incubation technique, we compared release of immunoreactive thromboxane B2 by colonic biopsies from patients with ulcerative colitis, Crohn's disease and controls, and assessed the inhibitory effect of picotamide, a thromboxane synthesis inhibitor-receptor antagonist, which has been widely used in Italy for management of ischaemic heart and cerebrovascular disease. RESULTS: Increased amounts of thromboxane B2 were released from biopsies from patients with active ulcerative colitis (median 238 pg/20 min/mg wet weight (interquartile range 147- 325), n = 12) and active Crohn's disease (252 (174-450), 6) compared with those from patients with quiescent ulcerative colitis (95 (61- 140), 12) or Crohn's disease (105 (57-201), 13), or controls (136 (64- 206), 8). Incubation with picotamide at concentrations between 100 microM and 1 mM reduced thromboxane B2 release (IC50 890 microM). CONCLUSION: Since increased thromboxane A2 production may have pathogenetic importance, thromboxane synthesis inhibitor-receptor antagonists such as picotamide merit therapeutic trial in the management of inflammatory bowel disease.     

龙眼参提取物对耐药口腔上皮样癌细胞株KB／MIT及耐药乳腺癌细胞株MCF-7／ADR的逆转作用

目的：研究龙眼参提取物XCKB／MIT细胞及MCF-7／ADR细胞株的耐药逆转作用。方法：设计4个不同浓度的龙眼参提取物组，采用MTT方法．测定体外培养的阿霉素敏感株MCF-7及其耐药株MCF-7／ADR以及米托蒽醌敏感株KB及其耐药株KB／MIT的IC50。结果：MCF-7／ADR耐药株及KB／MIT耐药株在龙眼参提取物与阿霉素或米托蒽醌的联合用药中其IC50值分别接近于单独用约于敏感株MCF-7和KB的水平．而与单独用药于耐药株其IC50有显著性差异。结论：龙眼参提取物可以逆转MCF7／ADR和KB／MIT的耐药性。     

浆细胞病患者IL-4产生细胞数减少的意义及机制探讨

本文运用APAAP法检测了16名浆细胞患者外周血细胞在PHA刺激下产生IL-4的能力。发现浆细胞病组阳性细胞比率明显低于正常对照组(P<0.001),且阳性细胞比率与患者血清中多克隆IgM、IgA水平呈正相关(r=0.806和r=0.703)。在正常人外周血中加入CRP50mg/L,经PHA刺激后IL-4产生细胞也明显减少。作者假设,由于IL-6增高引起CRP等急性期相蛋白大量分泌,使IL-4产生受到明显抑制,从而使B细胞激活发生障碍是浆细胞病中多克隆免疫球蛋白合成抑制的主要原因。

蝎毒素Ⅳ的中枢镇痛作用

从东亚钳蝎粗毒中分离纯化出蝎毒素Ⅳ，经套管注入侧脑室，用辐射热测痛和屈肌反射检测两种方法，观察蝎毒素Ⅳ的中枢镇痛作用，结果蝎毒索Ⅳ可以明显延长大鼠缩腿潜伏期，并可显著抑制Ｃ纤维诱发的屈肌反射。提示蝎毒素Ⅳ具有显著的中枢镇痛作用。
