西菲律宾海硅藻席沉积中的多囊虫类放射虫记录及其环境意义

为了多角度理解海洋纹层沉积物的形成过程,利用在西菲律宾海采集到的含纹层硅藻席的XT47孔岩心样品,进行多囊虫类放射虫的组合变化与环境意义分析.研究表明XT47孔岩心上段260 cm厚硅藻席沉积中含有丰富的放射虫、丰度高于2×104个/克;中段260～460 cm出现5次放射虫丰度高峰与红粘土的交替旋回沉积;下段460～...     

药棒穴位疗法对中风后上肢痉挛患者的效果观察

目的：观察药棒穴位疗法对中风恢复期肢体拘挛患者的护理效果。方法：将80例中风后上肢痉挛患者随机分为干预组和对照组,每组各40例,对照组按照常规护理内容进行护理,观察组在对照组的基础上运用药棒护理技术。采用改良的ASHWORTH评分测评2组上肢痉挛程度,根据ASHWORTH评分改善情况评定疗效。结果：总有效率干预组为92.5%,对照组为72.5%,2组比较,差异有统计学意义（P＜0.05）;2组干预后ASHWORTH评分均较干预前有不同程度的好转,干预组较对照组改善更明显,差异均有统计学意义（P<0.05）。结论：药棒穴位疗法对中风后上肢痉挛患者的护理效果显著。     

壮药大火草保留灌肠治疗慢性前列腺炎60例临床观察

目的：观察壮药大火草保留灌肠治疗慢性前列腺炎（CP）的临床疗效。方法：将120例CP患者随机分为2组,每组各60例。治疗组予大火草保留灌肠治疗,对照组予宁泌泰胶囊和坦索罗辛胶囊治疗,观察2组患者的症状指数（NIH-CP-SI）评分和前列腺液（EPS）白细胞（WBC）计数变化。结果：2组NIH-CP-SI评分、WBC治疗前后组内比较及治疗后组间比较,差异均有统计学意义（P＜0.05或P<0.01）。结论：壮药大火草保留灌肠治疗CP可有效缓解疼痛,改善排尿症状和生活质量,降低EPS的WBC计数,临床疗效确切。     

Enzymatic properties of UFE, a novel marine fibrinolytic enzyme

A novel potent protease, Urechis unicinctus fibrinolytic enzyme (UFE), was firstly discovered. The enzymatic properties of UFE were further investigated. As a low molecular mass protein, UFE appeared to be very stable to heat and pH. When temperature was below 50 ℃, the remnant enzyme activity remained almost unchanged, but when temperature was raised to 60 ℃, the remnant enzyme activity began to decrease rapidly. UFE was quite stable in the range of pH value from 3 to 12, especially in slightly alkaline pH value. Mn2 , Cu2 and Fe2 ions were activators of UFE, while Fe3 and Ag ions were inhibitors of UFE. Fe2 ion along with Fe3 ion might regulate UFE activity in vivo. The optimum pH and temperature of UFE were about 8 and 50 ℃, respectively. Other characteristics of this enzyme were also studied. Systematic research results are significant when UFE is applied for medical and industrial purposes.     

排石散联合钬激光碎石术治疗肾结石40例临床观察

目的：观察壮药排石散联合钬激光碎石术治疗肾结石的临床疗效。方法：将80 例肾结石患者随机分成治疗组和对照组,每组各40 例。2组均采用钬激光碎石术治疗,术后治疗组给予排石散治疗,对照组给予盐酸坦索罗辛缓释胶囊治疗。比较2组结石有效清除率、结石排出时间、疼痛视觉模拟量表(VAS)评分及血尿、尿路感染、下尿路刺激征等并发症发生情况。结果：结石有效清除率治疗组为 95.00%(38/40),对照组为80.00%(32/40),2组比较,差异有统计学意义(P＜0.05)。结石排出时间治疗组短于对照组,治疗后2组VAS评分均较治疗前下降,且治疗组低于对照组;术后血尿、尿路感染、下尿路刺激征发生率治疗组均低于对照组,差异均有统计学意义(P＜0.05或P＜0.01)。结论：排石散联合钬激光碎石术治疗肾结石可显著提高结石清除率,缩短结石排出时间,减轻患者疼痛程度,减少术后并发症的发生,值得临床推广应用。     

渤海涟虫类和软体动物幼虫食性的观察

根据消化道内食物分析结果得出：涟虫类、三叶针尾涟虫和驼背涟虫、瓣锶类后期幼虫和腹足类后期幼虫都营浮游植物食性,以硅藻类为主要食物。细长涟虫以星脐圆筛藻、未查明的圆筛藻和辐射圆筛藻为主要摄食对象;三叶针尾涟虫以舟形藻和新月菱形藻为主要摄食对象;驼背涟虫以辐射圆筛为主要摄食对象。鳃类后期幼虫以辐射圆筛藻和未查明的圆筛藻为主要摄食对象;腹足类后期幼虫以未查明的圆筛藻、辐射圆筛藻和中心圆筛藻为主要摄食对象
