3.Advance of mini-invasive treatments of hepatic portal hypertension in cirrhosis
Journal of Medical Postgraduates 2003;0(05):-
The therapeutic management of hepatic portal hypertension in patients with cirrhosis is still a challenge. At present surgical devascularization and shunting play the important roles in treatment of portal hypertension. While some cirrhotic patients can not bear the stress of operation and anesthesia because of inadequat potential hepatic function. So the mortality of operation is very high. With the development of endoscopy,radiological techniques and new materials and equipments, the mini invasive treatments become more important. This review summarizes the current advances of mini invasive treatments of portal hypertension in cirrhosis.
4.Experimental study of arsenic trioxide on rabbits with hepatic Vx-2 carcinoma by transcatheter arterial infusion
Journal of Third Military Medical University 2003;0(16):-
Objective To evaluate the anticancer effect of arsenic trioxide (As 2O 3) on rabbits with hepatic Vx 2 carcinoma by transcatheter arterial infusion (TAI). Methods Rabbits with hepatic Vx 2 carcinoma were treated with As 2O 3 by TAI for 7 d consecutively. The tumor inhibitory rate and the average tumor weight were determined. The morphological changes of the tumor were observed with a transmission electron microscope. bax/bcl 2 and VEGF expressions were examined by immunohistochemistry. Results The average weight of the tumor was 7.99, 6.50, and 4.87 g, and the tumor growth inhibitory rates in the experimental groups were 50.31%, 59 58%, and 69 71%, respectively. Tumor growth was significantly inhibited as compared with that in the NS group ( P
6.Advances in the research of carrier materials for implant drug delivery system within bone
International Journal of Biomedical Engineering 2006;0(06):-
Implant drug delivery system(IDDS) is helpful to the therapy of infection、tuberculosis and tumor of bone. With the development of tissue engineering, various materials has been used as the carriers for the IDDS. Research of the carrier materials used in implant drug delivery system is reviewed in this article.
7.Clinical progress of anti-epidermal growth factor receptor antibody,cetuximab,in the treatment of colorectal cancer
Chinese Journal of Clinical Pharmacology and Therapeutics 2004;0(07):-
Recent clinical trials suggested that epidermal growth factor receptor (EGFR) targeted agents could benefit many patients with colorectal cancer. This article reviews the clinical efficacy of cetuximab, which is an antibody directed at the EGFR, in the treatment of metastatic colorectal carcinoma. Several articles about EGFR-targeted therapies in metastatic colorectal carcinoma and other solid tumors were reviewed. Cetuximab showed the increase in progression-free survival (3.98 months vs 2.56 months, P
8.Advancement in stimuli-sensitive drug delivery system
International Journal of Biomedical Engineering 2011;34(6):367-370
Stimuli-sensitive drug delivery system (SSDDS) is an novel drug delivery carrier.It is sensitive to either the internal physiopathologic changes (pH,temperature) of the body or external stimulus signal (ultrasound,magnetic signal) and controls the release of the drugs that it carries according to the variation of physicochemical property which stimulated by the signals.SSDDS can be prepared from hydrogels,liposomes and magnetic nanoparticles.In contrast to non-stimuli-responsive drug delivery system,SSDDS has remarkable advantages including feedback regulation,stronger controllability and targeting therapy.This paper will review the advancement in stimuli-responsive drug delivery system in recent years.
9.Advancement of the preparation technology of the porous scaffolds for the tissue engineering
International Journal of Biomedical Engineering 2008;31(4):242-245,257
As an essential element of tissue engineering,the shape,pore size,and porosity of the porous scaffolds have direct influence on the attachment,proliferation,and differentiation of seeding cell as well as their properties.So it is important to be able to prepare an ideal porous scaffold which is able to provide the cells with an excellent micrcenvirenment in order to support their growth and differentiation.In this article,we reviewed some kinds of the preparation technologies of the porous scaffolds for tissue engineering,including fiber bonding,emulsion freeze drying,solvent casting/particulate leaching,high-pressuro processing,gas foaming/particulate leaching,thermally induced phase separation,and electro-spinning,with focus on rapid prototyping.It is our belief that the combination of the basic technologies and the rapid prototyping technology which is able to control the properties of the scaffolds and could be applied for individualized scaffold construction would be the major focus of research in the future.
10.The research status of preclinical animal experiments of gene therapy for Leber congenital amaurosis
Chinese Journal of Experimental Ophthalmology 2014;32(8):764-768
Leber congenital amaurosis (LCA) is extremely severe hereditary retinal dystrophy,because it leads to congenital bilateral blindness in early childhood.With the development of molecular genetics and the therapeutic gene replacement technology,gene therapy clinical trials have obtained exciting results on the basis of relatively satisfied with preliminary clinical experimental results by adeno-associated virus (AAV) vector-mediated gene therapy in the past decade.These researching methods include intravitreal injection and subretinal space injection of gene vector,and the investigating indexes include evaluations of visual function and safety,such as immune reaction of the animals,ocular histopathological change,complications and bio-distribution of gene sequence.The preliminary success of the LCAⅡ Ⅱ gene therapy will give some clues to the other inherited retinal diseases.This review focuses on the present status of pre-clinical animal experiments of its gene therapy.
