From May, 1990 to Sept., 1993 106 cases of primary liver cancer were treated by temporary or permanent hepatic arterial embolization with Bletilla striata powders (permanent, 56 cases) or gelfoam powders (temporary, 50 cases) under controlled technical conditions, in term of degree of tumor

OBJECTIVE To evaluate and compare the effect of combined transarterial chemoembolization (TACE) and arterial administration of Bletilla striata (a Chinese traditional medicine against liver tumor) versus TACE alone for the treatment of hepatocellular carcinoma (HCC) in ACI rats. METHODS Subcapsular

OBJECTIVE To evaluate the characteristics of Bletilla striata microspheres (BSMs) and its effects as an embolic agent in a rabbit model. METHODS BSMs were prepared with an emulsifification-cool condensation-chemical cross-linking method. The characteristics of BSMs in vitro were observed.

To assess the effect of different embolic agents in curing craniofacial tumors and vascular diseases, 21 patients who were treated by intra-arterial embolization were divided into three groups: gelfoams, bletilla striatas and coils. The results showed that 8 cases of preoperative patients in

The polysaccharide fraction of Bletilla ochracea (BOP) was isolated from its tubers, and purified by DEAE-52 Cellulose and Sephadex G-200 column chromatography. The structural features of BOP were analyzed by GC-MS, HPLP, FT-IR, methylation and NMR. The average molecular weight of BOP was

Tumour-associated macrophages (TAMs) are a set of macrophages residing in the tumour microenvironment. They play essential roles in mediating tumour angiogenesis, metastasis and immune evasion. Delivery of therapeutic agents to eliminate TAMs can be a promising strategy for cancer immunotherapy but

OBJECTIVE A system of stearic acid (SA)-modified Bletilla striata polysaccharide (BSP) micelles was developed for the targeted delivery of docetaxel (DTX) as a model anticancer drug (DTX-SA-BSP). METHODS Particle size, zeta potential and DTX release in vitro were measured in release media at

OBJECTIVE To study the mechanism of inhibition of tumor angiogenesis by Bletilla colloid. METHODS Human Hep-G2 hepatocellular carcinoma cells were cultured and treated with Bletilla colloid of different concentrations. Pure culture of Hep-G2 cells was used as control and pure culture medium without

7-Hydroxy-2-methoxy-phenanthrene-3,4-dione and 3',7',7-trihydroxy-2,2',4'-trimethoxy-[1,8'-biphenanthrene]-3,4-dione, two novel compounds and four known compounds were isolated from Bletilla striata. The structures of the compounds were established on the basis of extensive spectroscopic analysis.

Eight stilbenoids, 1-(p-hydroxybenzyl)-4,8-dimethoxyphenanthrene-2,7-diol (1), 2,7-dihydroxy-1,3-bis(p-hydroxybenzyl)-4-methoxy-9,10-dihydrophenanthrene (2), 4,7-dihydroxy-1-(p-hydroxybenzyl)-2-methoxy-9,10-dihydrophenanthrene (3), 3,3'-dihydroxy-2',6'-bis(p-hydroxybenzyl)-5-methoxybibenzyl (4),

Bletilla striata, a traditional Chinese medicine, has been used for the treatment of alimentary canal mucosal damage, ulcers, bleeding, bruises and burns. B. striata polysaccharide (BSP) isolated from B. striata was found to enhance vascular endothelial cell (EC) proliferation and vascular

When the skin is injured, the subcutaneous tissues and organs are threatened by pathogens and excessive water loss. Wound dressings are, therefore, needed to protect the wound site from infection and improve the wound closure. Natural polysaccharides have been applied for various biomaterials

Postoperative peritoneal adhesions (PPAs) constitute a common complication of abdominal surgery with a high incidence. Bletilla striata (BS) is an important hemostatic drug used in China for nearly 2000 years. The purpose of this study was to investigate the effect of Bletilla striata

Bletilla striata polysaccharides (BSPs) have been used in pharmaceutical and biomedical industry, the aim of the present study was to explore a BSPs amphiphilic derivative to overcome its application limit as poorly water-soluble drug carriers due to water-soluble polymers. Stearic acid (SA) was
