ObjectiveTo get known of the knowing and utilization of essential public health services among community residents for clinical visits in Nanchang city, and to provide evidence for promoting the effective use of public health services. MethodsA total of 20 community health services (CHS) organizations were finally selected by stratified random sampling method from 5 administrative regions in Nanchang city. Questionnaire survey about the knowing and utilization of public health services was performed to the 500 residents. We used EpiData 3.0 software to establish the database and SPSS 17.0 software for statistical analysis. ResultsThe awareness rate about essential public health services among them was 77.6% in Nanchang, which was highest to 91.0% in Wanli district and lowest to 47.0% in Xihu district. The differences between the administrative regions were significant (χ2=75.893, P=0.000). The archiving rate in CHS organizations among visits was 59.2%, which was up to 84.0% in Wanli district and lowest to 40.0% in Qingshanhu district. It also showed statistical significance between the regions (χ2=110.493, P=0.000). The total utilization rate about essential public health services was 95.8% in the population, which was no significant difference between the regions (χ2=7.772, P=0.100). However, the utilization rate in different populations was statistically significant (P < 0.05). ConclusionThe awareness rate and archiving rate about essential public health services among the residents in CHS organizations in Nanchang was not high, but the utilization rate was much higher, which was different among the administrative regions. The CHS organizations should strengthen the publicizing of essential public health services knowledge for the people in different regions to improve the co-development of the regions. In addition, it is also necessary to improve the use of community health services among the populations to achieve the goal about the equalization of essential public health services.
ObjectiveTo compare difference in the establishment of animal model of cartilage defect by resection of medial collateral ligament and meniscus and by cartilage excavation so as to provide a proper way for the choose of animal model preparation of catilage defect. MethodsTen healthy beagles, male or female, weighing 5.0-10.0 kg, were randomly divided into 3 groups. Resection of knee collateral ligament and meniscus was performed on 4 beagles of group A, cartilage excavation of knee-joints in 4 beagles of group B, and no treatment on 2 beagles of group C as controls. At 16 weeks after modeling, MRI, gross observation, HE staining, Safranin O staining, and toluidine blue staining were performed, and Osteoarthritis Research Society International (OARSI) score was recorded. ResultsMRI and histology observation showed no obvious cartilage defect in group A; obvious cartilage defects were observed in group B and gross observation showed dramatic dark red cartilage defects. OARSI score was significantly lower in group A (0.940±0.574) than group B (4.500±0.516) (t=18.461, P=0.000). ConclusionThe cartilage excavation is better than resection of both meniscus and medial collateral ligament, which provides a good method of establishing an animal model of cartilage defect at 16 weeks after operation.
