摘 要 目的 制备透明质酸(HA)修饰的负载大黄素(EMD)的多壁碳纳米管(MWCNTs)递药系统(HA-MWCNTs-EMD),并研
究其对乳腺癌细胞的体外抑制作用。方法 将EMD负载于MWCNTs,制得递药系统MWCNTs-EMD;进一步以HA进行修饰,制
得递药系统HA-MWCNTs-EMD;对上述两种递药系统进行表征。以游离EMD为参照,考察上述两种递药系统的体外释药情况,
检测两种乳腺癌细胞(MCF-7、MDA-MB-231细胞)对系统中EMD的摄取情况,并检测两种递药系统对两种乳腺癌细胞表面糖蛋
白分化群44(CD44)表达、活力、凋亡、乳酸脱氢酶(LDH)释放量的影响。结果 MWCNTs-EMD、HA-MWCNTs-EMD的包封率均
为(63.52±2.74)%,载药量分别为(25.01±1.83)%、(12.13±1.96)%,粒径分别为(865.95±2.16)、(351.86±1.68)nm,多分散性指
数分别为0.54±0.02、0.23±0.01,Zeta电位分别为(23.87±0.14)、(-42.79±0.39)mV。MWCNTs-EMD、HA-MWCNTs-EMD在2、
4、6、8、10、12、24 h 时的 EMD 累积释放量均显著低于同期游离 EMD,而 HA-MWCNTs-EMD 显著高于同期 MWCNTs-EMD(P<
0.05);两种乳腺癌细胞对MWCNTs-EMD、HA-MWCNTs-EMD中EMD的摄取量均显著高于其对游离EMD的摄取量(P<0.05);
与游离 EMD 组比较,MWCNTs-EMD、HA-MWCNTs-EMD 组两种细胞的凋亡率、LDH 释放量均显著升高,表面 CD44 的表达
(MWCNTs-EMD 组除外)、细胞活力均显著下调或降低,且 HA-MWCNTs-EMD 的作用更显著(P<0.05)。结论 成功制备负载
EMD 的新型递药系统 HA-MWCNTs-EMD;该递药系统具有一定的缓释作用,可明显降低乳腺癌细胞活力,促进其凋亡并增加
LDH释放,且上述抗乳腺癌作用明显强于游离EMD和MWCNTs-EMD。

ABSTRACT OBJECTIVE To prepare hyaluronic acid (HA)-modified emodin (EMD)-contained multi-walled carbon nanotubes
(MWCNTs) drug delivery system (HA-MWCNTs-EMD) and explore its in vitro inhibitory effect on breast cancer cells.
METHODS EMD was loaded onto MWCNTs to prepare a drug delivery system MWCNTs-EMD; subsequently, the system was
further modified with HA to obtain the drug delivery system HA-MWCNTs-EMD. The two drug delivery systems mentioned above
were characterized. With free EMD as the reference, the drug release in vitro of the above two drug delivery systems was
investigated; the uptake of EMD by two breast cancer cells (MCF-7, MDA-MB-231 cells) was detected. The impacts of the above
two drug delivery systems on the expression of surface glycoprotein differentiation group 44 (CD44), activity, apoptosis and
lactate dehydrogenase (LDH) release of two breast cancer cells were detected. RESULTS The encapsulation efficiencies of
MWCNTs-EMD and HA-MWCNTs-EMD were both (63.52±2.74)%, with drug loading rates of (25.01±1.83)% and (12.13±
1.96)%, particle sizes of (865.95±2.16) and (351.86±1.68) nm, polydispersity indexes of 0.54±0.02 and 0.23±0.01, and Zeta
potentials of (23.87±0.14) and (-42.79±0.39) mV, respectively. The 2, 4, 6, 8, 10, 12 and 24-hour cumulative release rates
of EMD in MWCNTs-EMD and HA-MWCNTs-EMD were
