BACKGROUND: Bone cement coated by different materials has various characteristics and causes varying therapeutic effects. OBJECTIVE: By comparing characteristics of CPC, CPC/D, and CPC/M/D3 to investigate the preparation of doxorubicin microspheres-coated bone cement. METHODS: Doxorubicin microspheres were prepared with multiple emulsion solvent volatilixation method. Doxorubicin microspheres were mixed with CPC as the ratio of 3:7 to prepare doxorubicin microspheres-coated bone cement. The samples were randomly divided into three groups: CPC group, containing bone cement alone; CPC/D group, containing doxorubicin;CPC/M/D group, containing doxorubicin microspheres. Scanning electron microscope at varying magnification was used to observe structural characteristics and measure the diameter of microspheres. X-ray diffraction was used to estimate the extent of CPC and CPC/M/D samples. The initial and final setting time of cement samples in the three different groups was measured at 25 ℃ and 37℃ respectively. The injectability and interval porosity of different samples were tested. The compressive strength of the specimens was measured using a universal material testing machine to record the maximal compressive strength and breaking strength. RESULTS AND CONCLUSION: PLGA microspheres (100-150 μm) were globular and the surface was slick and sly. Micrestructure of bone cement was not obviously changed following mixing with drugs, thus the location and characteristics of drugs in bone cement were not determined. Micrespheres-coated bone cement (100-150 μm) was distributed among CPC powder. All the X-ray diffraction pattern of three different samples was in coincidence with standard X-ray diffraction pattern of hydroxyapatite, i.e., the major peak was located near 32°. Additional drugs and microspheres did not cause new phases. Obvious collapsing was not observed in the three samples following immediately adding in saline, but the collapsing appeared in both CPC/D and CPC/M/D samples after 24 hours. The setting-up time of CPC/M/D was the longest, but that of CPC was the shortest. On the other hand, the setting-up time was the longest at 37℃. The final setting-up time of CPC/M/D group was 45 minutes. The doxorubicin microspheres-coated bone cement showed the best property of injectability among the three kinds of cement. The interval porosity was the highest in the CPC/M/D group but the lowest in the CPC group. Interval porosity of doxorubicin microspheres-coated bone cement was up to 61.67%. The yield stress was the strongest in the CPC group but the weakest in the CPC/M/D group. Additionally, the yield stress of calcium phosphate cement dramatically decreased while doxrorubicin microspheres were coated. However, there was no significant difference between them. The preparation of doxorubicin microspheres-coated bone cement was reliable and the product had good structures and properties.

OBJECTIVETo investigate the main factors that influence measles morbidity and the genotype of measles virus, so as to provide evidence for scientific decision making to further control the prevalence of measles.
METHODA retrospective analysis included 182 children in Children's Hospital of Fudan University, diagnosed with measles from January 1, 2012 to December 31. The clinical and epidemiological characteristics, including the gender, age, the incidence of seasonal trends, measles vaccine vaccination history, contact history and other clinical manifestations, laboratory test results, and so on were analyzed. And the reverse transcription PCR (RT-PCR) was adopted to detect sputum specimens from suspected patients with measles,who were selected randomly,the sequence of the part of the PCR products was analyzed.
RESULT(1) Clinical and epidemiological data: Totally were 182 children with measles (125 males, 57 females) were enrolled into this study. The age of the patients ranged from 3 months to 89 months, 127 cases were younger than 9 months (69. 8%). The prevalence season was from April to August, while the peak month was April and May (22. 5%, 23. 1%). Among 182 hospitalized children, only 11 cases underwent measles vaccination (6. 0%), and among them 5 cases were within 2 weeks before disease onset. A total of 167 cases (91. 8%) had not been vaccinated, most of whom were immigrants, and the measles vaccination history of the remaining 4 cases were unknown. There was a positive correlation between the measles vaccination ratio in children of the floating population (8. 45%, 6/71) and the settled children (29.4%, 5/17, χ =8. 11 P =0. 004). In total, 24 cases (13. 2%) had definite measles exposure history, with 153 cases (84. 1%) of unknown origin,5 cases (2.7%) without any history of contact. (2) Clinical manifestations: All the 182 patients had fever (100%) and obvious rashes (100%), among them 145 cases had body temperature higher than 39 °C (79. 7%). The fever period ranged from 2 to 38 days. Among 182 hospitalized children,165 cases (90. 7%) had typical measles,17 cases had atypical measles. Among the 17 cases, two had severe measles, one had heterotypic measles. (3) The common complica tions: 96 cases had pneumonia (52. 8%), 80 had laryngitis (44. 0%), 38 had bronchitis (20. 9%),15 had hepatic dysfunction (8. 2%), 11 had myocardial damage (6. 0%), 3 had febrile seizures (1. 6%), and no patient had encephalitis. Of the 96 cases with pneumonia, 92 received sputum test; 38 were sputum culture positive (41%). The dominant pathogens were Streptococcus pneumoniae(11/38,29%), Haemophilus influenzae (6/ 38,16%), Moraxella catarrhalis (4/38, 11%), Escherichia coli (4/38, 11%), Candida albicans (4/38, 11%), Mycoplasma pneumoniae (4/38, 11%) and Staphylococcus aureus (3/38, 8%). (4) The H1a genotype was the only one genotype in the detected sequence of 54 measles virus strains.
CONCLUSIONMeasles was more often seen in the children under the age of 9 months from the floating population. The morbidity peak month was from April to May in Shanghai. The H1a genotype was the only one genotype. We should try to improve vaccination coverage rate in the children who are at the age for vaccination, so as to prevent measles outbreak.

Objective To investigate the effects of dexamethasone on expressions of epithelial neutrophil activating protein-78 (ENA-78) and transforming growth factor- beta 1 (TGF-β1) in neutrophil of asthma rats.Methods Thirty male SD rats were randomly divided into three groups on average, including asthma group, control group and dexamethasone treated group. In this experiment, the rat model of asthma were established by sentization and challenge with ovalbumin. Blood neutrophil were isolated and purified. The expression of ENA-78 was detected by flow cytometry. The expression of TGF-β1 was detected by immunohistochemical method in blood neutrophil and bronchial wall. Results Expression of ENA-78 in blood neutrophil in dexamethasone treated group(71.82 ±8. 87 mean fluorescence intensity)was lower than that in asthma group, but higher than that in control group(all P <0. 01). And expressions of TGF-β1 protein in dexamethasone treated group(0. 173 ± 0. 014,0. 202 ± 0. 019 optical density, respectively) was lower than that in asthma group(all P <0. 01) ,but higher than that in control group(all P <0. 01). There were significant positive correlation between ENA-78 expression at blood neutrophil and numbers of total inflammation cells in bronchoalveolar lavage fluid (n = 29, γ = 0. 762, P < 0. 01). Conclusion The beneficial effect of glucocorticoid(dexamethasone) on airway inflammation in asthma rats could be at least in part due to their direct inhibitory effect on ENA-78 and TGF-β1 protein generation by neutrophil.
