腮腺良性和恶性多形性腺瘤的超声研究

目的研究腮腺良性和恶性多形性腺瘤的超声特点,为临床医师诊治提供有效依据。方法选取腮腺良性多形性腺瘤患者79例和恶性多形性腺瘤患者15例,对其肿块的大小、硬度、内部回声、彩色多普勒血流显像(CDFI)特点结合病理学诊断进行对照研究。结果恶性多形性腺瘤的声像图特点与良性多形性腺瘤相似,但其肿瘤相对较大,质地更硬,内部回声分布更紊乱。不同性质的肿瘤的大小和质地有显著性差异,(P<0.01)。结论多形性腺瘤的超声诊断主要依据二维图像之特点。当多形性腺瘤大于3.0 cm,硬度较硬,内部回声分布不均多提示恶性。     

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.     

经皮穿刺颈椎髓核成形术治疗多间隙颈椎间盘突出症

目的:探讨经皮穿刺颈椎髓核成形术(percutaneous cervical nucleoplasty,PCN)治疗多间隙颈椎间盘突出症的临床疗效及其对颈椎稳定性的影响。方法:对我院2003年7月～2005年6月因颈椎间盘突出症住院行PCN治疗的64例患者进行回顾性研究,根据手术间隙分为两组:单间隙组(A组)34例,多间隙组(B组)30例。临床效果评价采用JOA评分标准(17分制并计算改善率),颈椎稳定性评价采用Katsumi标准。比较两组的临床效果及颈椎稳定性。结果:随访6～24个月,A组平均14.1±3.7个月,B组平均13.9±3.8个月,A组术前JOA评分为9.19±2.64分,术后为14.37±1.42分,改善率为66.3%;B组术前JOA评分为8.89±2.31分,术后为14.33±1.28分,改善率为67.1%,与术前比较均有显著性差异(P<0.001),两组患者的JOA评分改善率无显著性差异(P>0.05)。两组患者术后颈椎稳定性与术前比较均无显著性差异(P>0.05)。结论:PCN治疗多间隙颈椎间盘突出症效果优良,对颈椎稳定性影响小,不会造成颈椎失稳。

中国研制出抗禽流感药物——路透社目前,中国已研制出一种与“达菲”相应的抗禽流感病毒药物,但并没有说明该药物何时会投入使用,以及它与“达菲”的可比性。鉴于缺乏禽流感疫苗,世界卫生组织已经建议各国政府储备“达菲”。该药虽然不能治愈禽流感,但可以抑制病毒发展,减缓病毒扩散。全球唯一能够生产“达菲”的瑞士罗氏公司上星期宣布,他们已经停止在中国市场     

何以解忧惟有监管

没有监督的权力会导致腐败，这是一个显而易见的道理。尽管每一组织、机构、行业乃至个人都必须建立和遵从各自的行业道德和职业操守，但保证每个社会单元都能进退有序，除了建章立制的条令约束，更需要来自第三方的行之有效的监管。事关民生疾苦的医疗卫生无疑首当其冲。

还原型谷胱甘肽在预防糖尿病大鼠勃起功能障碍中的研究

目的探讨还原型谷胱甘肽(GSH)在预防糖尿病大鼠勃起功能障碍中的作用。方法通过腹腔注射链脲佐菌素65mg/kg建立糖尿病大鼠模型,然后随机分成DM组和DM+GSH组,DM+GSH组每天肌肉注射GSH200mg/kg。10周后观察大鼠勃起功能,并获取海绵体组织检测其谷胱甘肽、一氧化氮合酶(NOS)与丙二醛(MDA)水平,用TUNEL法检测细胞凋亡。结果成功建立糖尿病大鼠模型。与未注射GSH的DM组相比,DM+GSH组和正常对照组(C组)勃起功能更好,勃起率分别是20%,62.5%和100%。GSH水平DM+GSH组和C组明显比DM组高,其3组含量每克蛋白分别是(75.83±15.62)、(61.47±8.65)和(35.03±12.29)mg(P<0.05);NOS水平在DM+GSH组每毫克蛋白为(133.9±31.9)U,与正常对照组每毫克蛋白为(142.2±31.2)U相当,但较DM组每毫克蛋白为(58.4±18.9)U高(P<0.05);MDA含量在DM组每毫克蛋白为(3.71±0.62)nmol,明显高于正常对照组和DM+GSH组(P<0.05),这两组每毫克蛋白为(2.08±0.34)nmol和(2.44±0.28)nmol;细胞凋亡率在DM组、DM+GSH组和C组的分别是(22.6±3.6)%、(10.8±1.7)%和(7.2±2.1)%(P<0.05)。结论还原型谷胱甘肽对糖尿病大鼠阴茎组织有较好的抗氧化作用,能减少细胞凋亡,对延缓糖尿病性ED的发生有一定的作用。
