MRI技术对高原人群颅脑脱髓鞘疾病回顾性研究

目的研究高原地区,脱髓鞘疾病与中老年人疾病等因素的关系。方法对我院所有接受过磁共振头部扫描的病人进行评估,确诊出40位脱髓鞘疾病患者,并对大脑7个部位的脱髓鞘疾病按严重性分4级打分,统计临床数据,最后运用统计学方法分析其相关性。结果在40例患者中,出现在大脑半球、放射冠、半卵圆中心和脑室前后角的脑白质损伤频率最多,分别占总量的50%、67.5%、77.5%和87.5%。脑白质损伤患者的平均年龄为47.1岁,这比世界其他地区都有明显的提前。男性患者将近是女性患者的3倍(29∶11)。年龄、慢性高原红细胞增多症、收缩压、脑梗塞与脑白质损伤正相关(P<0.05)。结论对于高海拔地区,有效控制高原心血管疾病的发生对于减少颅脑脱髓鞘疾病的发生具有重要意义。

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.     

早期脑室置管行颅内压监护对中型颅脑损伤患者的预后影响

目的　探讨早期脑室置管行颅内压 (ICP)和脑灌注压 (CPP)监护在中型颅脑损伤中的临床应用价值。方法　将 12 5例伤后 2 4h入院无手术指征的中型颅脑损伤 (GCS 9～ 12分 )患者 ,随机分为ICP监护组 :入院后即经恻脑室内穿刺置管行ICP与CPP连续监测 ,根据颅内压变化调整治疗方案 ;对照组 :入院后不做ICP监测 ,依据临床观察的意识及生命体征变化 ,进行治疗。结果　颅内压监护组脱水剂剂量、应用时间均低于对照组 ,疗效优于对照组 ,两组差异有显著意义 (P <0 0 5 )。结论　中型颅脑损伤病情极不稳定 ,早期行ICP监护能及早发现病情变化 ,对及时采取有效治疗措施 ,降低死残率 ,改善预后有重要意义。     

奥沙利铂为主的静脉化疗联合腹腔温热灌注和体外高频透热治疗晚期大肠癌的临床观察

目的 探讨奥沙利铂为主的化疗联合腹腔温热灌注治疗晚期肠癌的临床效果.方法 对42例晚期大肠癌患者,予腹腔温热灌洗化疗及体外高频透热治疗,联合以奥沙利铂为主的静脉化疗,至少2个周期,观察疗效及不良反应.结果 全组患者完成169个周期治疗,CR 5例,PR 22例,SD 8例,PD 7例,总有效率66.3%.完全缓解率11.9%.不良反应以白细胞下降及消化道反应多见,少数患者出现周围性神经毒性,以I-Ⅱ 度为主.结论 以奥沙利铂为主的静脉化疗联合腹腔温热灌注和体外高频透热治疗,对晚期大肠癌具有一定的疗效,毒副作用小;腹腔局部化疗是一种值得关注的治疗途径.     

Analysis of the Surface Ozone During Summer and Autumn at a Coastal Site in East China

The levels and temporal variations of surface ozone at a coastal site in East China during summer and autumn were analyzed and the influences of meteorological parameters on ozone were investigated. An inland city was chosen as a comparison site. The main results and conclusions of this study are: (1) ozone pollution, with a maximum 1 h concentration of 150.98 ppbv, was severe during summer and autumn at the coastal site; (2) the ozone level was obviously higher at the coastal site than that at the inland site in September; (3) besides temperature and solar radiation, sea-land breeze circulation is an important factor influencing the ozone level at the coastal site, and sea breeze often induce high ozone levels (the average ozone concentration for sea breeze was about 13 ppbv higher than that for land breeze).
