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.     

Expression of cytochrome p450 and other biotransformation genes in fetal and adult human nasal mucosa.

Despite recent progress in the identification and characterization of numerous nasal biotransformation enzymes in laboratory animals, the expression of biotransformation genes in human nasal mucosa remains difficult to study. Given the potential role of nasal biotransformation enzymes in the metabolism of airborne chemicals, including fragrance compounds and therapeutic agents, as well as the potential interspecies differences between laboratory animals and humans, it would be highly desirable to identify those biotransformation genes that are expressed in human nasal mucosa. In this study, a global gene expression analysis was performed to compare biotransformation enzymes expressed in human fetal and adult nasal mucosa to those expressed in liver. The identities of a list of biotransformation genes with apparently nasal mucosa-selective expression were subsequently confirmed by RNA-polymerase chain reaction (PCR) and DNA sequencing of the PCR products. Further quantitative RNA-PCR experiments indicated that, in the fetus, aldehyde dehydrogenase 6 (ALDH6), CYP1B1, CYP2F1, CYP4B1, and UDP glucuronosyltransferase 2A1 are expressed preferentially in the nasal mucosa and that ALDH7, flavin-containing monooxygenase 1, and glutathione S-transferase P1 are at least as abundant in the nasal mucosa as in the liver. The nasal mucosal expression of CYP2E1 was also detected. These findings provide a basis for further explorations of the metabolic capacity of the human nasal mucosa for xenobiotic compounds.

胆盐/磷脂混合胶束对疏水性天然药物增溶性能的研究

目的:研究胆盐/磷脂混合胶束(BS/PC-MM)体系对疏水性天然药物的增溶能力及影响因素。方法:选择不同纯度的大豆磷脂(SPC)、蛋黄磷脂(EPC)与高纯度的胆酸盐制备胆盐/磷脂混合胶束(BS/PC-MM)。以透光率方法测定胆酸盐对磷脂的溶解能力,以20(S)人参皂苷Rg3、Rh2、黄芪甲苷、20(S)原人参二醇、原人参三醇和呋喃二烯为疏水性模型药物,考察了SDC/SPC-MM对药物的增溶特性。结果:高纯度的大豆磷脂和蛋黄磷脂适合制备成澄明的BS/PC-MM溶液。胆酸盐对磷脂的增溶能力为,脱氧胆酸钠>胆酸钠,胆酸盐对蛋黄磷脂的溶解度增加略高于大豆磷脂。20(S)原人参二醇、原人参三醇和呋喃二烯与SPC的亲和性较高。而20(S)人参皂苷Rh2、Rg3和黄芪甲苷与SDC的亲和性强,SDC/SPC-MM的脂质总质量增加,疏水性药物的溶解度提高。结论:胆盐/磷脂混合胶束(BS/PC-MM)对疏水性药物具有较好的溶解度,增溶能力受药物的理化性质和混合胶束的组成影响,可成为疏水性药物的非肠道给药新型载体。     

脑脊液药理实验条件规范化初探——当归芍药散精简方的神经保护作用

目的:通过观察当归芍药散精简方(FBD)含药脑脊液对过氧化氢所致PC12细胞损伤模型的保护作用,对脑脊液药理实验条件规范化进行初步探讨。方法:以MTT法观察不同实验条件下(给药方案、添加量、处理方法、批次及保存时间),FBD大鼠含药脑脊液对过氧化氢损伤的PC12细胞存活率的影响。结果:过氧化氢损伤的PC12细胞存活率随FBD含药脑脊液添加量增加而提高;相同添加量多次给药(2次/d×3.5 d)含药脑脊液的保护率均高于单次给药的含药脑脊液;未处理含药脑脊液与经56℃、乙醇、丙酮处理含药脑脊液对PC12细胞均有显著的保护作用(P<0.01),各组保护率无明显差异;同时观察到不同批次大鼠及不同保存时间的含药脑脊液对受损PC12细胞均有显著保护作用,但随保存时间的延长,其保护率下降。结论:含药脑脊液的制备可采用连续多次给药方案,无需灭活处理,一般以体外添加终体积的10%,-20℃冻存不超过30 d为宜。
