乳腺良恶性病变的磁共振T2*W首过灌注成像与血管生成相关性研究

Objective： To study the diagnostic value of T2^＊-weighted first-pass perfusion imaging in breast tumors. Methods： We analyzed the magnetic resonance imaging （MRI） information along with the pathological and immunohistochemistry results. Magnetic resonance imaging was performed in 28 patients with breast tumor. The time to signal intensity curves were generated according to the T2^＊-weighted first-pass perfusion imaging. The curve＇s maximal signal intensity drop rate and maximal signal intensity decrease time were analyzed and compared with the pathological diagnoses after surgery. Results： Malignant breast lesions showed higher maximal signal intensity drop rate （44.69% ± 17.07 vs. 17.22% ±7.49, P 〈 0.001） than benign lesions, but there was no significant difference of maximal signal decrease time between those two lesions （23.94 s ± 4.92 vs. 20.02 s ± 6.83, P 〉 0.05）. Conclusion： The T2^＊-weighted first-pass perfusion imaging has enough sensitivity and specificity in breast tumor diagnosis.

Feasibility of treating hyperfibrinogenemia with intermittently administered batroxobin in patients with ischemic stroke/transient ischemic attack for secondary prevention.

This study evaluated the safety and efficacy of batroxobin in treating hyperfibrinogenemia for secondary stroke prevention. Patients with ischemic stroke or transient ischemic attack (TIA) were measured for plasma fibrinogen levels. Selected participants had concomitant hyperfibrinogenemia (plasma fibrinogen > or = 3.0 g/l). Patients enrolled between 1 July 2003 and 31 December 2004 were treated with batroxobin; patients enrolled between 1 January 2002 and 30 June 2003 were treated without batroxobin. Batroxobin was administered intermittently via intravenous injection at 3-monthly intervals. Patients in both groups were followed for 1 year. Any cerebrovascular events and suspected adverse events were recorded. In total, 112 ischemic stroke/TIA patients with concomitant hyperfibrinogenemia were enrolled, 52 being treated with batroxobin and 60 without batroxobin. Six patients (11.5%) with batroxobin and 16 patients (26.7%) without batroxobin had recurrent cerebral ischemic events during follow-up. Stroke/TIA recurrence in patients without batroxobin was higher than that in patients with batroxobin (P < 0.05). Two patients with batroxobin and two patients without batroxobin developed hemorrhagic stroke during follow-up. There were five deaths (9.6%) in the batroxobin group, and seven deaths (11.7%) in the nonbatroxobin group during follow-up (P > 0.05). Intermittent intravenous injection of batroxobin can efficiently reduce the risk for stroke/TIA recurrence in patients with concomitant hyperfibrinogenemia.     

两种隐匿阴茎大鼠模型的建立及比较

目的:建立稳定的大鼠隐匿阴茎模型,为探索阴茎包埋对海绵体结构和功能的影响提供实验动物模型。方法:90只2周龄雄性SD大鼠随机均分为A、B、C3组,A组采用阴茎根部内荷包缝合法,B组采用包皮折叠缝合法包埋阴茎,C组为假手术组。在180d内观察两种方法的包埋效果。结果:A组术后4只死于急性尿潴留,5只因尿道口周围软组织感染、皮肤破溃导致包埋失败,3只因包埋过松阴茎伸出;B组术后1只死于麻醉,2只死于急性尿潴留;因阴茎发育和勃起,A组有7只、B组有10只阴茎伸出;C组1只死于麻醉。A组和B组中其余大鼠均有较好的包埋效果,A组包埋成功率为36.7%,B组为56.7%,而且可以在实验中任何时候解除包埋。结论:包皮折叠缝合法和阴茎根部内荷包缝合法均能建立稳定的、且与人类隐匿阴茎自然病程较为一致的2周龄大鼠隐匿阴茎动物模型。

心理干预对宫颈癌患者心理问题的作用

宫颈癌是严重危害妇女健康的恶性肿瘤之一，当前的治疗方法是以手术为主，切除患者子宫不同部位，会导致患者周期性例假消失，性生活质量降低，身体激素分泌失衡，加上术后全身性的治疗，给患者带来心理上不同程度的创伤，出现很多心理问题。暴怒、悲伤、焦虑等可以引起免疫力的降低，这对于治病是不利的。有一些病人能正确对待疾病，配合医师进行治疗，情绪稳定，与疾病斗争的意志较强，往往比那些被癌症吓得不知所措的病人治疗效果要好得多。
