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.

Objective To detect the methylation status of CDH1 3 gene promoter in colon cancer by using methylation-specific polymerase chain reaction(MSP)technique.Method The tissue specimens from 32 cases of colon cancer(observation group),and 12 cases of normal colon tissues(control group)were examined,the methylation of CDH13 gene promoter was detected by MSP.Result The methylation of CDH13 gene promoter was detected in 19 cases(59.4％,19/32)in observation group,1 case(8.3 ％,1 / 12)in control group,there was statistical significance between two groups(P =0.002).Conclusion Frequency of the methylation of CDH13 gene promoter is apparently higher in colon cancer tissues than that in normal colon tissues,it reveals that CDH13 gene promoter may contribute significantly to the development of colon cancer.

A case of mandible plasma cell myeloma is reported.Plasma cell myeloma is a monoclonal neoplastic proliferation of plasma cells of bone-marrow derivation,usually multi-centric but jaw bones are rarely involved.The treatment requires precise pathological diagno-sis.The prognosis of solitary jaw bone lesions can be good after treatment.

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.
