胰腺癌血管形成与其病理特征及预后的关系

目的探讨胰腺癌组织中微血管生成与其病理特征及预后的关系。方法应用免疫组化S-P法以CD34单克隆抗体特异性标记胰腺癌组织血管内皮细胞及正常胰腺组织血管内皮细胞,检测其微血管密度(MVD)并与临床病理特征及预后对比分析。结果胰腺癌组织中微血管密度明显高于正常胰腺组织(51.3±21.5、26.6±9.2,P<0.01)。MVD与肿瘤大小及病理类型无关,而淋巴结转移(P<0.01)、肿瘤细胞分化程度(P<0.05)、临床分期(P<0.01)和预后明显相关。结论胰腺癌组织中微血管密度高于正常胰腺组织,其微血管生成与病理特征及预后有密切关系。

A cell-based high-throughput screening assay for Farnesoid X receptor agonists

Objective To develop a high-throughput screening assay for Farnesoid X receptor （FXR） agonists based on mammalian one-hybrid system （a chimera receptor gene system） for the purpose of identifying new lead compounds for dyslipidaemia drug from the chemical library. Methods cDNA encoding the human FXR ligand binding domain （LBD） was amplified by RT-PCR from a human liver total mRNA and fused to the DNA binding domain （DBD） of yeast GAL4 of pBIND to construct a GAL4-FXR （LBD） chimera expression plasmid. Five copies of the GAL4 DNA binding site were synthesized and inserted into upstream of the SV40 promoter of pGL3-promoter vector to construct a reporter plasmid pG5-SV40 Luc. The assay was developed by transient co-transfection with pG5-SV40 Luc reporter plasmid and pBIND-FXR-LBD （189-472） chimera expression plasmid. Results After optimization, CDCA, a FXR natural agonist, could induce expression of the luciferase gene in a dose-dependent manner, and had a signal/noise ratio of 10 and Z＇ factor value of 0.65, Conclusion A stable and sensitive cell-based high-throughput screening model can be used in high-throughput screening for FXR agonists from the synthetic and natural compound library.     

个性化护理干预对妇科恶性肿瘤手术后生活质量的影响

[目的]探讨个性化护理干预对妇科恶性肿瘤手术后生活质量的影响。[方法]将46例在我科因妇科恶性肿瘤手术的患者随机分为实验组和对照组，通过实施个性化护理干预，对两组患者进行SF-36量表和Olson婚姻质量问卷进行测评。[结果]对妇科恶性肿瘤手术后患者进行个性化护理干预后其生活质量明显提高，差异有显著性意义（P〈0．01）。[结论]个性化护理干预能提高妇科恶性肿瘤手术后生活质量。     

肝靶向牛血清白蛋白脂质体的制备及理化性质研究

目的:研制肝靶向牛血清白蛋白(bovine serum albumin,BSA)脂质体,并研究其理化性质,为蛋白质药物的肝靶向给药提供一种新模型。方法:首先采用逆相蒸发法制备BSA负电荷脂质体,再用O-羧甲基-N-乳糖酰化壳聚糖(O-carboxymethyl N-galactosylated chitosan,Gal-CMCS)修饰,制备肝靶向BSA脂质体,并考察脂质体的形态、粒径、Zeta电位、包封率及稳定性等理化性质。结果:制得的肝靶向BSA脂质体在电镜下呈类圆形,粒径分布均匀,平均粒径为(284.1±5.41)nm,BSA包封率为(34.21±1.73)%,Zeta电位为( 27.1±1.17)mV,4℃下放置3个月粒径和包封率无明显变化。结论:成功制备了肝靶向BSA脂质体,其具有良好的稳定性和较高的药物包封率,可作为蛋白质药物肝靶向给药的一种新模型。     

Experimental study of natural hydroxyapatite/chitosan composite on reconstructing bone defects

Objective:To study the possibility of natural hydroxyapatite/chitosan composite on repairing bone defects. Methods:We developed a natural hydroxyapatite/chitosan composite that could be molded into any desired shape. The powder component consists of natural hydroxyapatite, which is epurated from bone of pigs. The liquid component consists of malic acid and chitosan. Operations were performed on the left tibias of 15 white rabbits to create two square bone defects. One of the defects was reconstructed with the composite, while the other was not repaired and used as a blank control. Three of the animals were killed at the end of 2 weeks, 4 weeks, 8 weeks, 12 weeks and 16 weeks respectively and implants were evaluated anatomically and histologically. Results:No apparent rejection reaction was found, except for a mild inflammatory infiltration observed 2 weeks after surgery. Fibrous tissue became thinner 2～8 weeks after surgery and bony connections were detected 12 weeks after surgery. The new bone was the same as the recipient bone by the 16th postoperative week. Conclusion:The hydroxyapatite/chitosan composite has good biocompatibility and osteoconduction. It is a potential repairing material for clinical application.
