    • 摘要: 背景:以钛合金为基底进行表面改性进一步提高其表面生物活性是目前研究的热点,而掺锶改性是提高植入物骨整合性的有效手段。目的:介绍以医用钛合金为基底掺锶改性的研究进展。方法:以“钛合金,锶,骨组织,成骨”为中文检索词,以“titanium(ti),strontium(sr),bone,osteogenic”为英文检索词,在中国知网和PubMed数据库检索2000年1月至2016年4月期间有关医用钛合金掺锶改性方面的文献。结果与结论:①医用钛合金具有较好的生物相容性,且与人体骨弹性模量接近,因而广泛应用于临床骨修复的植入物;②单纯钛合金表面生物活性较差,难以和骨组织结合达到骨整合;③对钛合金进行表面功能改性是行之有效的方案,而掺锶改性可显著促进新骨生成,达到骨与钛合金的整合;④目前掺锶改性的钛合金植入物及支架材料大多还处于体外实验和动物实验阶段,快速、稳定、易获得且安全有效的改性方法仍需进一步研究。%BACKGROUND:Surface modification of titanium surface to improve its biological activity is the research hotspot. Strontium-doped coating is considered to be an effective approach to promote the implant osseointegration. OBJECTIVE:To introduce the research progress of strontium-modified biomedical titanium al oys.METHODS:Articles related to the medical titanium al oys modified with strontium published from January 2000 to April 2016 were retrieved from CNKI and PubMed databases. The keywords were“titanium (Ti), strontium (Sr), bone, osteogenic”in Chinese and English, respectively. RESULTS AND CONCLUSION:Titanium al oys have been widely used in bone implantation because of their good biocompatibility and similar elasticity modulus with human bones. However, pure titanium al oys have poor bioactivity which leads to weak bone-implant contact. Surface modification is a good approach to enhance implant osseointegration. Sr-doped surface treatment can promote new bone formation and osseointegration. Most of the studies about Sr-doped modification are ongoing at the extracorporeal and animal experiment stage;therefore, further investigation is required to seek rapid, stable, available, safe and effective methods.

    • 摘要: BACKGROUND:Polyetheretherketone (PEEK) has the potential to carry short-range radiations for cancer treatment. However, there is a lack of bio-safety assessment focusing on125I irradiated PEEK particle chain. OBJECTIVE:To evaluate bio-safety of the 125I brachytherapy source irradiated PEEK particle chain. METHODS:PEEK particle chain extracts were prepared according to GBT-16886 and applied in acute toxicity test on mice and rabbits, rabbit pyrogen test and rabbit intradermal reaction test. Animals in experimental, material and negative control groups were given irradiated PEEK particle chain extracts, non-irradiated PEEK particle chain extracts and extracts, respectively, to compare the experimental results. RESULTS AND CONCLUSION:In mouse and rabbit acute toxicity test:irradiated PEEK particle chain extracts made no effects on the animal general conditions like breathing, activity, hair, secretion and body weight and morphology of the heart, liver, spleen, lung and kidney and other vital organs. In pyrogen test:the maximum temperature in three rabbits reached 0.4°C(<0.6°C), and the sum was 0.7°C(<1.3°C). In intradermal reaction test:the rabbit erythema and edema reaction scores both were 0. To conclude, 125I irradiated PEEK particle chain exhibits a good bio-safety, presenting no acute toxicity, pyogen reaction and intradermal reaction.%背景:研究表明聚醚醚酮很有潜质,能携带具治疗作用的短射程辐射物参与临床治疗。然而,目前国内外尚未有任何有关碘粒子辐照后聚醚醚酮及其复合材料的生物安全性评价。  目的:评价125I密封籽源辐照的聚醚醚酮粒子链的生物安全性。  方法:参考GBT-16886制作聚醚醚酮粒子链浸提液,进行小鼠、兔急性毒性实验、兔热原实验及兔皮内刺激性实验。实验分3组,实验组、材料对照组及阴性对照组分别给予辐照后聚醚醚酮粒子链浸提液、未辐照聚醚醚酮粒子链浸提液和浸提液进行对比观察实验。  结果与结论:①兔及小鼠急性全身毒性实验:聚醚醚酮粒子链辐照后浸提液对全部动物的呼吸、活动、毛发、分泌物、体质量等一般情况以及心肝脾肺肾等重要脏器的病理组织学等均无影响;②热原实验:有3只兔的体温升高最大值为0.4°C(<0.6°C),总和为0.7°C(<1.3°C);③皮内注射实验:兔红斑和水肿反应评分均为0;④结果说明:聚醚醚酮粒子链辐照后浸提液无急性全身毒性、无热原反应,无皮内注射刺激性反应,说明经125I粒子辐照后的聚醚醚酮粒子链生物安全性良好。

    • 摘要: BACKGROUND:Polyhydroxybutyrate-co-volerate (PHBV) is a noticeable tissue engineering material of polyhydroxyalkanoates family. It has the properties of low immune rejection response and good biocompatibility, and its degradation products are non-toxic. OBJECTIVE:To investigate the biocompatibility of PHBV membrane material and human bone marrow mesenchymal stem cel s in vitro. METHODS:Human bone marrow mesenchymal stem cel s at passage 3 were seeded upon PHBV membrane as experimental group and upon conventional culture plates as control group. Then we calculated the adherent cel number of two groups at 1, 2 and 4 hours and got the cel adherent rate. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide assay was used at days 2, 4, 6, 8 to observe the cel proliferation of two groups. Fluorimetric method with the fluorescent dye Hoechst 33258 was used to detect the DNA content of cel s at days 3, 6, 9 and 12 in both groups. After cel s were seeded upon PHBV membrane for 5 days, the cel growth upon the material was examined under a scanning electron microscope. RESULTS AND CONCLUSION:When the cel s were cultured for 1 hour, the adherent rate in the experimental group was lower than that in the control group;but there were no significant differences between two groups at the other two periods. No difference was found in the cel proliferation and the DNA content between the two groups. Human bone marrow mesenchymal stem cel s seeded upon PHBV membrane for 5 days grew wel with spindle morphology and the intercel ular connections were tight and more extracel ular matrices were observed by scanning electron microscopy. Taken together, PHBV membrane material shows a good biocompatibility with human bone marrow mesenchymal stem cel s.%背景:聚羟基丁酸/戊酸酯共聚物是近年来受到重视的聚羟基脂肪酸族组织工程支架材料,具有免疫排斥反应低、生物相容性好和降解产物无毒副作用的优点。  目的:观察聚羟基丁酸/戊酸酯共聚物膜材料与人骨髓间充质干细胞的体外生物相容性。  方法:将第3代人骨髓间充质干细胞种植于聚羟基丁酸/戊酸酯共聚物膜上作为实验组,培养板单纯培养细胞作为对照组,计算1,2,4 h两组贴壁细胞的数量,得出细胞贴壁率。MTT比色法观察2,4,6,8 d两组细胞的增殖情况。采用Hoechst33258荧光法,检测3,6,9,12 d两组细胞内的DNA含量。将人骨髓间充质干细胞接种聚羟基丁酸/戊酸酯共聚物膜材料上5d后,电镜扫描观察细胞在材料上的生长情况。  结果与结论:共培养1h时,实验组的细胞贴壁率低于对照组;其他时间段两组之间细胞贴壁率差异无显著意义。两组各时点间的细胞增殖差异无显著意义。两组各时间点细胞内DNA含量差异无显著意义。扫描电镜观察人骨髓间充质干细胞在聚羟基丁酸/戊酸酯共聚物膜上生长良好,形态呈梭形,细胞间连接紧密,分泌较多细胞基质。证明聚羟基丁酸/戊酸酯共聚物膜材料与人骨髓间充质干细胞有良好的生物相容性。

    • 摘要: 背景:目前国内将硅烷偶联用于金属表面预处理的报道较少。目的:对NaOH碱处理的钛片行硅烷化改性,观察硅烷膜的表面形貌与结构特征及细胞相容性。方法:对制得的纯钛试件行NaOH碱处理,然后分别以8%,15%,33%浓度的KH-550硅烷偶联剂进行改性处理,以纯钛片和碱处理的钛片为对照组,采用扫描电镜观察改性处理钛片表面微观形貌,采用能谱仪分析改性处理钛片表面的成分。将纯钛片、碱处理的钛片及不同浓度 KH-550硅烷偶联剂改性处理的钛片分别与犬骨髓间充质干细胞共培养,观察材料表面细胞的形态及黏附。结果与结论:硅烷膜由许多呈脑浆状的小片构成,排列紧密,主要由C、N、O、Si等元素组成。当硅烷溶液浓度为8%时,钛表面难以形成较完整的硅烷膜;当硅烷溶液浓度为15%时,钛表面形成的硅烷膜表面较8%浓度组钛表面相对较完整,但可仍见有较多裂纹,难以形成致密的硅烷膜;当硅烷溶液浓度为33%时,纯钛表面能形成致密的硅烷膜。犬骨髓间充质干细胞在33%浓度硅烷膜处理后钛基体上的黏附情况明显优于纯钛、碱处理钛片及8%,15%浓度硅烷膜处理后的钛片。说明33%硅烷化改性纯钛表面硅烷膜较完整,并且具有良好的生物相容性,可促进骨髓间质干细胞在活性层表面的黏附。

OBJECTIVE:To observe the surface appearance, structure and biocompatibility of NaOH pre-treated titanium sheet coated with silane films. n METHODS:The NaOH pre-treated titanium sheet was silanized with the silane coupler (KH-550) at different concentrations (8%, 15%and 33%). The test specimens manufactured with different concentrations of silane treatment solutions were analyzed with scanning electron microscope and energy dispersive spectroscopy analyzer, in comparison with pure titanium and alkali-pretreated titanium sheets as controls. After silanization, bone marrow mesenchymal stem cel s from dogs were co-cultured with the test specimens to observe the cel morphology and adhesion on the surface of test specimens. n RESULTS AND CONCLUSION:The silane film consisted of brain shaped sheets which arranged closely. The composition of the silane film was C, N, O and Si. The test specimen coated with the 33%silane solution had the ful silane film, while the silane film was imperfect at a concentration of 8%. The cel adhesion was better on the surface of test specimens treated with 33%silane solution than the other specimens. These findings indicate that the titanium sheet modified with 33%silane solution possesses a good biocompatibility, thereby improving the cel adhesion, spreading, proliferation and differentiation.
