Influenza virus is a virus causing upper respiratory tract infection disease with high morbidity and mortality. China is considered as an area with high rate of influenza morbidity. Prevention and treatment of influenza currently rely on vaccines and antiviral agents in the world. In addition, traditional Chinese medicines also have been used in clinical for influenza therapy. In vitro anti-influenza virus activities of 10 traditional Chinese medicines were studied by cytopathic effect (CPE). Qingre Jiedu oral liquid (factory H) had strong antiviral activity against influenza virus A/Guangdong Luohu/219/2006 (H1N1); Yinhuang oral liquid had strong antiviral activity against influenza virus A/Hanfang/359/95 and A/Yuefang/243/72 (H3N2). Qingkailing oral liquid (factory G) had strong antiviral activity against influenza virus A/Jifang/15/90 (H3N2). Qingre Jiedu oral liquid (factory H) had strong antiviral activity against influenza virus A/Jifang/15/90, A/Yuefang/243/72 (H3N2) and virus B.

Ribavirin is a broad-spectrum inhibitor against several unrelated DNA or RNA viruses in vitro and in vivo. In this paper the in vitro and in vivo study of anti-influenza virus activity of ribavirin (RBV) injection had been reported. The in vitro antiviral activity of ribavirin injection against influenza virus A and B was studied by CPE. The in vivo protective action of ribavirin injection against influenza A/FM/1/47(H1N1) mouse adapted strain infected mouse was studied with mouse model. The results showed ribavirin injection has strong inhibitory activity against 7 virus strains tested in vitro. Ribavirin injection could significantly increase virus infected mouse survival rate and survival days and improve lung pathogen and lung index.

BACKGROUND: The core of bone tissue engineering is to construct a scaffold that is similar to human bone tissue structure and features.OBJECTIVE: To compare pathochemical and mechanical characteristics between pig and human bone scaffold materials.DESIGN, TIME AND SETTING: Contrast study was performed at Clinical Anatomy Institute, South Medical University; Guangdong Province Key Laboratory of Tissue Construction and Detection from March to December 2006.MATERIALS: Four fresh health adult human cadavers were provided by South Medical University, Guangzhou Red Cross Society, and the relatives knew the fact. Ultra low temperature freezing 6-month iliac bones of 6 adult swines were also used in this study.METHODS: Pig iliac and healthy adults iliac bones were obtained to remove soft tissue, curettage periosteum and bone marrow. Bone sawing machine was used to cut cancellous bone into smaller bone sections around 5 mm×5 mm×40 mm, which underwent ultrasonic cleaning, H2O2 and alcohol soaking, freeze drying and radiation treatment; finally, xenogeneic bone scaffold and allogeneic bone scaffold were obtained.MAIN OUTCOME MEASURES: Xenogeneic bone scaffold material and human allograft bone scaffold were observed with scanning electron microscopy to compare porosity, contents of protein content, calcium and phosphorus, and mechanical properties.RESULTS: Xenogeneic bone scaffold and allogeneic bone scaffold both had intrinsical bone trabecula, trabecular spaces and bone cavity system. Both of them had unabridged natural three dimensional network structure. The 3D supporting frames of them were complete. The xenogeneic bone scaffold had more spaces than allogeneic bone scaffold. The size of both scaffolds was approximation, about 400 μm. The interval porosity of xenogeneic bone scaffold was higher than the allogeneic bone scaffold (P<0.05). And the protein of xenogeneic bone scaffold was not as many as it of allogeneic bone scaffold (P<0.05). The contents of Ca and P were similar (P>0.05), and there was no significant difference in Young's modulus of xenogeneic bone scaffold and allogeneic bone scaffold (P>0.05).CONCLUSION: Xenogeneic bone scaffold may completely meet the clinical demands for bone grafting or be the scaffold of bone tissue engineering in mechanical chemical properties.

Objective To identify the quality of life (QOL)and major influencing factors for migrant workers in Zhejiang province.Methods The QOL of 1217 migrant workers and 1387 permanent urban residents in Zhejiang province were measured by WHOQOL-BREF scale (Chinese version)in a stratified sampling.A multiple linear regression model was used to analyze the relationship between the factors and the scores of the four domains.Results There were no significant statistical differences(P＞0.05)found in the scores of physical health,social relationship and general health between migrant workers and urban residents.Their scores of psychological health,surrounding conditions and general quality of life,however,were found lower than urban residents (3.5 ± 0.8 vs 3.6 ± 0.8).Influencing factors for their psychology were education,family conflicts and appetite; those for their surrounding conditions were daily average work hours and appetite.Conclusion Given improvements in the quality of life of migrant workers,rooms to improve were found in such scores as psychological health and surrounding conditions.

Objective To probe into the inequality found in primary public health service available to the migrant population and permanent residents. Methods With on-site interviews, 581 migrant workers and 581 permanent residents in a county in Zhejiang province were surveyed, to learn the inequalities between the two in the expenditure, access and outcomes of the public health service accessible to each. Results only 7. 8% of the migrant population ever had access to medical aid, a ratio far below that of the permanent residents; 40. 9% of the migrant population may turn down medical service beyond their affordability, a ratio far higher; for the migrant population, their ratio of gynecological checkup is 58. 7%, lower than that of the permanent residents (67. 7%). Conclusion Resources and financial allocation to institutions of public health should be enhanced, and social medical and insurance system should be developed and improved, in an effort to encourage the equality of primary public health services accessible to various sectors of the population.
