Model Evaluation

Model identification: After 6 weeks, take caput femoris and collect aorta abdominalis blood. Then kill rabbits in blank group and model group using air embolization method.
Blood specimen: Forbidden diet for 24 hours before sampling, collect aorta abdominalis blood under general anesthesia into a glass tube, refrigerate, centrifuge, remove upper serum into EP tube, save at -20℃.
Caput femoris specimen: After blood collection of abdominal aorta, take the right caput femoris in an aseptic condition. Dissect along the coronal plane and place in 4% paraformaldehyde, electron microscope fixation solution and liquid nitrogen in turn.
Observe appearance and quality of caput femoris, color and shape of arthrodial cartilage. Feel the hardness of the bone using a knife.

Pathological Results

Using HE staining, observe changes in form, structure and quantity of trabeculae, osteocyte, pulp cavity and hematopoietic cells under a light microscope to determine whether the model is successful or not.
Randomly select 10 fields under high power lens, count 50 bone lacuna in each field, calculate blank bone lacuna rate.
HE staining contains sampling, decalcification, embedding, slicing and staining.

Cytokines Level

1. Determine ALP in serum of each group by chemical colorimetry, determine TG by oxidase method according to the instructions.
2. Detect protein expression of p-ERK1, p-ERK2, p-JNK and p-P38 by Western blotting.

Statistical Analysis

SPSS software is used for statistical analysis, measurement data to mean ± standard deviation (x ±ｓ), using t test and single factor analysis of variance for group comparison, P<0.05 indicates there was a significant difference, P<0.01 indicates there are very significant differences.
