OBJECTIVE:To optimize the formulation parameters of poly1,3-bis(p-carboxyphenoxy) propane-sebacic acid (P(CPP∶SA)) microsphere and evaluate its drug release performance in vitro. METHODS: The paclitaxel microspheres were prepared by single emulsion method,and the effects of the factors such as the stirring speed (A),P(CPP∶SA) concentration (B),emulsifier polyvinyl alcohol (PVA) concentration (C) on encapsulation efficiency were evaluated by orthogonal test. The surface morphology of the prepared microsphere was observed and its drug release performance in vitro was evaluated. RESULTS: The optimal formulation of the microsphere obtained was as follows: A was 4 000 r?min-1,B was 80 mg?mL-1 and C was 1%,respectively. The morphology of microspheres was round and intact. The encapsulation efficiency of paclitaxel was up to above 90%. The sustained release duration was 30 days with an accumulative release rate of over 80%. CONCLUSION: Paclitaxel microspheres prepared by optimal formula display a high encapsulation efficiency and satisfactory sustained-release pattern.

Hospital Information System(HIS) contributes a lot to the management of the hospital with the personnel flow,the material flow,the fund flow and the information flow well-regulated.The construction of HIS has to be based on general scheme,and then the sub-systems are established separately,at last all sub-systems are integrated to form a system,that is HIS,to realize the modernization of the hospital management.

In recent years,scientific reports say that ApoE genotypes not only influence lipid metabolism but also affect bone metabolism through vitamin K. Primary osteoporosis is mainly regulated by genes and the interaction of genes and environmental factors also affects primary osteoporosis. This review focused on the mechanism of the influence of ApoE gene on bone mineral density and interaction of ApoE gene and environment factors in the determination of primary osteoporosis.

This study explores the association between physician-patient communication and healthcare service quality,and relevant factors.The physician-patient communication belongs to medical behaviors,and plays a key role in the improvement of physician-patient relationship and the overall healthcare service quality.The consults of physician-patient communication were affected by many factors including physicians' attitude,and usage of words and behaviors,in which the positive attitude and behaviors are key solution to the improvement physician-patient relationship.Therefore the urgent matters are to strengthen standardized management of physician-patient communication,and set up related regulations and effective measure.

This study was aimed to investigate the functions and indications ofRehmannia glutinosa from old herbalism documents. The database management system ofPu-Ji-Fang was used to summarize the whole function, which was compared with theChinese Pharmacopoeia 2010 edition. The results showed that besides the same function,R. glutinosa was also widely used in the treatment of various heat syndromes, deficiency, sore ulcer, traumatism, irregular menstruation, arthralgia, blood stasis, apoplexia, cough, restlessness, and etc. With modern studies on pharmacodynamics and clinical applications, potential functions ofR. glutinosa were primarily conformed as clearing heat-fire (clearing heat-toxin), tonifying, promoting blood circulation to remove blood stasis, soothing nerves, calming liver to extinguish wind, and removing wind-damp syndromes.

China is one of the countries where the prevalence rate of endemic fluorosis is very high.There are about one hundred million people suffering fluorosis.Many researchers are paying more and more attention to this field.Recently,some researches indicated that particular nutrients can influence fluorosis.This article reviewed the relationship between intake of protein and energy,mineral,vitamin and the occurrence and sequelae of fluorosis.

Objective To study the growth inhibision effect of disodium cantharidinate and Vitamin B6 injection on hepatocellular carcinoma cell line HepG2.Methods Different concentrations of disodium cantharidinate and Vitamin B6 injection were applied on the hepatocellular carcinoma cell line HepG2.The inhibition rate of HepG2 growth was measured by MTT assay.The apoptotic rate was detected with flow cytometry,and the morphology of apoptosis was observed by fluorescence microscope.Results The growth of HepG2 cells was significantly inhibited as well as the apoptosis of HepG2 cells was significantly encouraged by disodium cantharidinate and Vitamin B6 injection(P

The effect of postburn serum on T lymphocyte proliferation response was studied. The results showed that postburn serum was able to inhibit T lymphocyte transformation. The degree of serum suppression correlated with reduced T lymphocyte transformation after burn. Postburn serum also showed significant suppressive activities upon both interleukin 2 (IL-2) production and interaction betweeen IL-2 and IL-2 receptor (IL-2R), but had no significant effect on interleukin 1 (1L-1) producticn. This result indicated that postburn serum might inhibit IL-2 production and response through certain pathway other than IL-1 production, resulting in impaired T lymphocyte proliferation response.
