Animal health systems initially established in Australia,Canada and other countries,played a very important role in prevention and control of animal diseases.Based on comparing the animal health systems of Australia with the veterinary medical system in China,some strategies was obtained for establishing a more reasonable official veterinary system and animal health system in China,thus speeding up the integration process of veterinary and human medical public health system.

The research on novel scaffold materials is now characterized by a transition from single element to composition, from inert materials to bioactive materials, and from macro- level to micro- level. With the rapid development of nano- technology and life sciences, the two concepts of nano- modification and biomimic construction joined the mainstream of the scaffold research. And in this field, the theory of bone generation net has been recently explored systematically and comprehensively. As a result, it has now become a research focus to obtain ideal bioactive scaffolds on the basis of current investigation. This paper highlights several types of promising scaffolds, discusses their recent research and application, and reviews the present situation concerning bioactive scaffolds

Objective To observe the effect of Yiqi Huaxian Decoction (YHD) on transforming growth factor ?1(TGF-?1 )mRNA expression in rats alveolar macrophages (AM) and pulmonary interstitial macrophages (IM).Methods Ninety-six Wistar rats were randomized into sham-operation group,model group,YHD (4 g?kg-1?d-1) group,and hydrocortisone (20 mg?kg-1?d-1) group.Bleomycin A5 was injected into the rats' trachea to induce pulmonary fibrosis.AM and IM were isolated for the culturing after modeling for 7 and 28 days.Molecular in-situ hybridization (ISH) was used for the detection of TGF-?1 expression in AM and IM.Results Percentage of cells in AM and IM with TGF-?1 positive expression and the score of optic density were increased in the model group (P

PURPOSE: Survival of metastatic breast cancer (MBC) patient remains unknown and varies greatly from person to person. Thus, we aimed to construct a nomogram to quantify the survival probability of patients with MBC. MATERIALS AND METHODS: We had included 793 MBC patients and calculated trends of case fatality rate by Kaplan-Meier method and joinpoint regression. Six hundred thirty-four patients with MBC between January 2004 and July 2011 and 159 patients with MBC between August 2011 and July 2013 were assigned to training cohort and internal validation cohort, respectively. We constructed the nomogram based on the results of univariable and multivariable Cox regression analyses in the training cohort and validated the nomogram in the validation cohort. Concordance index and calibration curves were used to assess the effectiveness of nomogram. RESULTS: Case fatality rate of MBC was increasing (annual percentage change [APC], 21.6; 95% confidence interval [CI], 1.0 to 46.3; p < 0.05) in the first 18 months and then decreased (APC, -4.5; 95% CI, -8.2 to -0.7; p < 0.05). Metastasis-free interval, age, metastasis location, and hormone receptor status were independent prognostic factors and were included in the nomogram, which had a concordance index of 0.69 in the training cohort and 0.67 in the validation cohort. Calibration curves indicated good consistency between the two cohorts at 1 and 3 years. CONCLUSION: In conclusion, the fatality risk of MBC was increasing and reached the summit between 13th and 18th month after the detection of MBC. We have developed and validated a nomogram to predict the 1- and 3-year survival probability in MBC.

Objective To explore the effects from different contact areas of the instrument causing trauma on biomechanical response parameters of rabbit skull fractures under quasi-static compression conditions. Methods The rabbits were divided into the scalp preservation group and scalp removal group. Each group was subdivided into 3 mm group, 6 mm group, 9 mm group according to contact diameter of the instrument causing trauma. There were 9 rabbits in each group, 54 rabbits in total. All rabbits were put to death by over anesthesia and made into a skull compression model. An electronic universal material testing machine was used to perform quasi-static compression of rabbit skulls to fractures, and biomechanical response parameters such as ultimate load, deformation under ultimate load and compressive strength of rabbit skulls in each group were detected. Results The differences in ultimate load, deformation under ultimate load, and compressive strength of rabbit skulls in scalp preservation group and scalp removal group under different contact areas were statistically significant. The ultimate load was positively correlated with the contact area, and the compressive strength was negatively correlated with the contact area. No correlation was found between deformation under ultimate load and contact area. For scalp preservation group and scalp removal group, the difference in deformation under ultimate load was statistically significant in the 3 mm contact surface diameter group, and there was no statistical significance in the other groups. Conclusions The contact area is positively correlated with the ultimate load of rabbit skull fracture and negatively correlated with compressive strength, while it has no correlation with deformation under ultimate load and is unrelated to whether the scalp is removed.
