坐骨棘筋膜固定术的临床解剖学研究

Objective The study was to explore the safety, firmness and convenience of the fascia around the ischial spine as a new fixation site for the vaginal fornix. Methods Between June 2007 and January 2008, detailed dissections and related measurements of the regions around the ischial spine were performed on 10 Chinese female cadavers (3 unembalmed and 7 embalmed cadavers). At the same time, the sacrospinous ligament,the fascia on the ischial spine, the iliococcygeus fascia as well as the vaginal fornix were exposed and the pull-out strength sequentially tested using a digital push-pull force gauge. Results The fascia on the ischial spine was firm and strong, with a thickness of 3 about mm. No major vessels or nerves were observed on the ischial spine. The greatest pullout strengths of the sacrospinous ligament,the fascia on the ischial spine, the iliococcygeus fascia as well as the vaginal fornix were (102±26),(64±15),(33±8)and(32±6)N, respectively. Conclusion The fascia at 1 cm from anterior lateral ischial spine, free of major vessels and nerves, is safe and strong and could be used as a new site for suspension in vaginal prolapse.

尿液潜血两种检验方法的比较

目的对尿液分析仪检测尿潜血反应和镜检红细胞（RBC）的结果进行分析比较。方法对400份门诊患者留取的随机尿液立即按照仪器操作说明进行尿液分析仪检验和尿沉渣显微镜检查。结果尿液分析仪潜血反应阳性，镜检有红细胞的有166例，镜检无红细胞的有24例。尿液分析仪潜血反应阴性镜检有红细胞的有12例，镜检无红细胞的有198例。两种方法结果出现差异。结论临床工作中尿液分析仪潜血反应与显微镜检查红细胞应联合进行，尤其是显微镜检查至关重要，不可忽视。

纳米粒载体传输Bcl-xl siRNA的抗肿瘤活性的研究

目的:制备纳米粒载体DMP,对其进行表征的测定,研究DMP介导的Bcl-xl siRNA的抗肿瘤活性。方法:采用MTT法对纳米粒的细胞毒性进行测定;通过Q-PCR法检测mRNA的含量,检测DMP递送Bcl-xlsiRNA入C26细胞的基因沉默效果;通过MTT法研究DMP/si RNA对C26细胞的抗肿瘤效果,测定其对C26细胞的肿瘤抑制作用;用克隆形成实验进一步证明DMP/siRNA能够抑制C26细胞生长,具有显著的抗肿瘤活性;采用碘化丙啶(PI)染色法流式细胞术来分析经过DMP/siBcl-xl治疗的C26细胞的凋亡率。结果:纳米粒具有良好的粒径和电位以及较低的细胞毒性,其IC50为3.7μg﹒mL~(-1)。Q-PCR结果显示DMP/siBcl-xl有效地降低了Bcl-xl信使RNA的水平;MTT结果显示DMP/siBcl-xl(50 n M和100 n M)的生存率分别为69.6%±3.3%,56.3%±1.9%,低于DMP组;克隆形成实验表明DMP/siBcl-xl能够抑制C26细胞的增殖,具有显著的抗肿瘤活性;凋亡实验结果显示DMP/siBcl-xl的细胞凋亡率为33.0%±3.8%,与对照组、DMP组、DMP/Scramble siRNA组比较,细胞凋亡率显著地增加了。结论:纳米粒DMP具有良好的粒径和电位,并且具有较低的细胞毒性。DMP/siBcl-xl能够沉默Bcl-xl基因,引发C26细胞的凋亡,进一步实现抑制C26细胞生长的治疗作用。实验表明纳米粒DMP能够作为有效的载体递送siRNA用于结肠癌的治疗。

不同工艺制得蒿甲醚pH依赖型固体分散体的比较研究

目的应用不同工艺制备蒿甲醚/HPMCAS(HF)固体分散体,通过含量、溶出度、收率的测定,阐明蒿甲醚pH依赖型固体分散体的最优制备工艺。方法以醋酸羟丙甲纤维素琥珀酸酯HPMCAS(HF)为固体分散体载体,通过3种工艺(共沉淀法、溶剂蒸发法及喷雾干燥法)制备蒿甲醚/HPMCAS(HF)固体分散体。考察其含量、收率以及在PH6.8和PH7.6环境下溶出度。结果原型药物及物理混合物溶出度均较低,喷雾干燥法制备的药物含量测定和收率都符合要求,在PH7.6的环境下能在2 h内完全溶出,明显高于另外两种方法。结论喷雾干燥技术制备的固体分散体显著改善蒿甲醚的溶出,而且有较好的pH依赖性,更适合用以蒿甲醚pH依赖型固体分散体的制备及工业生产。
