Cancer Research and Clinic 2014;26(8):568-570
Paclitaxel is one of the most effective broad-spectrum chemotherapeutic agents in the treatment of cancers.However,its clinical application has been limited due to its poor water solubility.Its current clinical administration results in serious side effects and has undesired pharmacokinetics and biodistribution.Therefore,it is need to develope alternate drug delivery systems of paclitaxel to enhance its solubility,permeability and stability,furthermore to promote a sustained,controlled and targeted delivery.Hyaluronic acid as the carrier of drug delivery system can solve the problems.Hyaluronic acid-paclitaxel nanoparticles have high anticancer efficiency in drug encapsulation and tumor cellular uptake,due to their appropriate size,surface modification and interaction with CD44.This review focuses on recent applications of hyaluronic acid-paclitaxel nanoparticles in a variety of malignant tumors.

OBJECTIVE: To study the relationship among the dosage, serum concentration and clinical effect of phenytoin(PHT) in treating epileptic patients .METHODS: 130 steady -- state serum concentrations of PHT were determined by fluores-cence polarization immunoassay(FPIA) in 70 patients with or without other drugs used in combination .RESULTS: The indi-vidual difference among the patients who received routine dosage of PHT was very significant. Intoxication occurred ex-tremely often in patients whose PHT serum concentrations were over 30?g/ml .CONCLUSION: It is necessary to perform TDM(Therapeutic Drug Monitoring) and individualize the use of PHT,so that the safe and effective use of drug can be ensured.

Pulmonary alveolar proteinosis (PAP) is a rare disease clinically, and at present no western medicine can effectively cure the disease. After the analysis of literatures related to Traditional Chinese Medicine (TCM) for treatment of the disease in the China National Knowledge Internet Database, it was discovered that the syndrome differentiation showed the disease closely associated with phlegm, blood stasis and yin deficiency. In this study, from view point of pulmonary gangrene TCM theory and treatment combined with PAP pathophysiological characteristics, it is emphasized that phlegm accumulation, blood stasis and yang deficiency are the key pathological manifestations of PAP, thus Yanghe decoction, Tounong powder, Kongxian pellet were used for treatment of one such case, the rational thinking in diagnosis and treatment of this patient being consistent with the idea learning western medicine for China use.

BACKGROUND:A cross-emulsification patented product of microporous polysaccharide hemostatic powder was prepared using potatoes as raw material with independent intel ectual property rights.
OBJECTIVE:To observe hemostasis effects of microporous polysaccharide hemostatic powder on soft tissue trauma.
METHODS:A wound, about 3 cm long and 0.5 cm deep, was made on the abdominal soft tissue of rabbits in the experimental group 1, and then microporous polysaccharide hemostatic powder, 1.0-2.0 g, was sprayed directly on the wound. In the experimental group 2, a wound, about 3.0 cm long and 1.0 cm deep, was made on the abdominal soft tissue of rabbits, and then microporous polysaccharide hemostatic powder, 1.0-2.0 g, was sprayed directly on the wound. Another rabbits with untreated wound served as controls.
RESULTS AND CONCLUSION:Microporous polysaccharide hemostatic powder formed a“pasty gel”covering the bleeding wound that achieved hemostatic effect. The bleeding time was (15.25±1.04) seconds in the experimental group 1 and (11.25±1.89) seconds in the experimental group 2. The marked effective and effective rates for hemostasis were 87.5%and 100%, respectively. In the control group, the bleeding time was more than 5 minutes. Hematoxylin-eosin staining showed mild muscle edema, vasodilatation of smal blood vessels, and few scattered endoplasmic neutrophils infiltrated at 24 hours after treatment with microporous polysaccharide hemostatic powder;til the 7th day, inflammation subsided, mild fibrosis was visible on muscle tissue surface, the hemostatic powder was completely absorbed, the wound tissue was close to the normal tissue, and there were no significant changes in muscle cells. These findings suggest that microporous polysaccharide hemostatic powder can be used for hemostasis of soft tissue trauma.

Objective To study preparation of micronized Shuanghuangpo hydrogel patch and its characteristics of transdermal penetration in vitro. Methods Micronized Shuanghuangpo hydrogel patch was prepared with some macromolecular water-soluble materials as gel base.The content of berberine was determined by HPLC method.Its transdermal penetration in vitro was determined according to the method of Chinese Pharmacopoeia 2010 edition. The rat skin penetration test in vitro was performed by modified Franz diffusion cell method. Results The hydrogel patch had constant content of berberine. Its release property in vitro conformed to Higuchi equation. The penetration of berberine in the hydrogel patch through the rat skin followed zero-order dynamics in 12 h.Its release rate was 7.934μg??(cm2)-1??h1/2 and percutaneous rate was 0.571μg??(cm2)-1??h-1. Conclusion The micronized Shuanghuangpo hydrogel patch is a new transdermal agent with sustained release property.
