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。     

The Application of Topical Anesthesia Combined with Subconjunctival Anesthesia for Glaucoma Surgery

Purpose: To evaluate the feasibility, reliability and analgesia effect of topical anesthesia combined with subconjunctival anesthesia in anti-glaucomatous surgery.Methods: Two hundred and four cases (357 eyes) underwent anti-glaucomatous surgeries under topical anesthesia with 0.5％ Alcaine eye drops combined with subconjunctival anesthesia with 2％ Lidocaine. The analgesic effect was analysed with visual analogue pain scale.Results: Among all of 357 eyes, 62 eyes underwent peripheral iridectomy, 67 eyes underwent simple trabeculectomy, 167 eyes underwent compound brabeculectomy and 12 eyes nonpenetrating trabecular surgery. The effects of anesthesia were as follows: 304 eyes (85.2％) were painless (Grade Ⅰ), 50 eyes (14.0％) were slight painful (Grade Ⅱ), and 3 eyes (0.8％) were more painful (Grade Ⅲ) during surgery. And no severe complications were observed in all the cases during surgery and postoperatively. Amaurosis fugax was not observed in the glaucoma patients at the late stage with narrow vi

脂肪性肝病的治疗对策

当前酒精性肝病(ALD)患病率居高不下，而非酒精性脂肪性肝病(NAFLD)发病率不断攀高，且起病渐趋低龄化，两者与病毒性肝炎并存者亦不少见。更为可怕的是，NAFLD不但与ALD相似，可导致肝硬化、肝细胞癌和肝功能衰竭，而且与2型糖尿病以及动脉硬化性心脑血管事件关系密切。然而迄今尚缺乏防治脂肪性肝病(FLD)的特效药物，现有对策主要为“提高认识、综合防治，加强宣教，重在实施”。     

输尿管上段结石的微创手术治疗

目的：探讨输尿管上段结石的治疗方法。方法：回顾性分析输尿管镜下气压弹道碎石(URSL），后腹腔镜输尿管切开取石(RLU)、经皮肾穿刺取石(PCNL)治疗输尿管上段结石患者的临床资料。其中URSL组25例，RLU组20例。PCNL组9例。结果：URSL组碎石成功18例；7例不成功，其中3例改为开放手术，1例改为后腹腔镜取石。2例行ESWL术，1例仅留置双J管。术后1个月拔管后自行排出。2例并发输尿管穿孔。RLU组取石成功18例，2例滑入肾内，经配合输尿管镜和腹腔镜直视下经皮肾穿刺取石成功，术后15例有伤口漏尿。PCNL组成功9例，无并发症。结论：USRL创伤小。术后恢复快。是治疗输尿管上段结石的较为满意的治疗方法。PCNL创伤小，取石成功率高，在结石靠近肾盂、儿童输尿管上段结石并同侧肾结石和结石以下输尿管狭窄时应优先考虑。但技术难度较大。RLU可作为URSL不成功后的辅助治疗方法。     

瘢痕成纤维细胞中TGF-β受体与整合素相互作用的实验研究

目的:了解TGF-β受体和整合素在瘢痕增生和挛缩过程中的作用.方法:通过荧光定量PCR法(FQ-PCR)测定经TGF-β受体、整合素和粘着斑激酶(FAK)抗体阻断后培养的瘢痕成纤维细胞TGF-β受体以及整合素表达量的变化.结果:经不同抗体阻断后培养的瘢痕成纤维细胞其TGF-β RI和整合素β 1的基因拷贝数均较阴性对照组有不同程度的下降(P＜0.05).结论:TGF-β受体和整合素介导的信号传导途径间可能存在着正反馈的效应,共同促进瘢痕的增生和挛缩.FAK是两条信号传导途径的交汇点和作用的中心环节.

系统性健康教育对改善焦虑病人症状的影响

焦虑症是以焦虑、紧张、恐惧等情绪障碍为主,常伴有自主神经系统症状和运动性不安等[1].主要表现为惊恐发作和广泛性焦虑两种形式.随着社会的发展、生活节奏的加快、竞争的激烈、社会分工的多元化、婚姻的变故、考试的不理想等生活事件,使人们的精神压力大为增加[2].以往的传统求稳心态已落后于时代的发展,一种以焦虑情绪为主的神经症已成为一个时代的现代疾病.焦虑症的发展有逐年上升的趋势,已受到更多人的关注和注意.对焦虑症病人实施系统性的健康教育,降低焦虑症的复发率具有重要的意义.……
