Objective To analyze the biological characteristics and morphologic features between the mouse models using MDA-MB-231 cells established by injecting tumor cell suspension or implanting tumor tissues. Methods Twenty BALB/c mice were randomly divided into two groups,with 10 in each group.The orthotopic models of breast cancer were established by injection of tumor cell suspension or implantation of tumor tissues in the fat pad of right second breast in the nude mice of the two groups,respectively.The time of tumor formation,success rate,tumor growth rate,shape,central tumor necrosis,blood vessel distribution and tumor ulceration were compared between the two groups of models.The histological features of the tumors were also observed. Results There were no significant difference in the success rate between the two methods.In the group of tumor tissues implantation,the tumors formed in an earlier time with various shape configurations,and they were hypovascular and vulnerable to central necrosis with the resultant superficial ulcerations.However,in the group with injection of tumor cell suspension,the tumors formed later with a regular shape,and the superficial ulceration was rare and not vulnerable to central tumoral necrosis since the tumors were abundant in blood vessels resulting in adequate nourishment.There were no significant difference in the pathological findings between the two groups. Conclusion The nude mouse models of breast cancer can be successfully established by both tumor tissues implantation and tumor cell suspension injection,with identical biological characteristics and fairly different morphological features.The investigators are well advised to choose the more appropriate one according to the purpose of the experiments.

Objective: To provide anatomic data for management of pterygopalatine fossa lesions via endoscopic transnasal approach. Methods: Fifteen (30 sides) formalin-preserved human skulls were subjected to microsurgical dissection to evaluate the exposure scopes of 3 different endoscopic surgery approaches: endonasal middle meatal transpalatine approach, endonasal middle meatal transantral approach, and endonasal inferior turbinectomy transantral approach. Meanwhile, 20 (40 sides) dry skulls were dissected and the related measurements were obtained. Results: The 3 approaches allowed for different exposure of the pterygopalatine fossa structure. The mean distances from foramen rotundum to anterior nasal spur, superior orbital fissure, and optic canal were (61.86±3.67)mm,(3.56±0.75) mm, and (11.23±1.24) mm, respectively. Conclusion: The 3 endoscopic approaches are safe and effective for resection of different pterygopalatine fossa lesions and foramen rotundum serves as a landmark for safe management of the pterygopalatine fossa.

This study was aimed to explore the methodology regarding culture, proliferation and purification of adipose-derived stromal cells (ADSCs), and to study their biological characteristics. ADSCs were obtained using type I collagenase digestion method. Cell growth was observed, and cell viability were detected under different digestion period by MTT. The ADSCs were then identified and induced. The results showed that adherent cells digested by type I collagenase for 60 min had a strong proliferation capability. After the induction of different inducers these adherent cells could differentiate into nerve cells and fat cells. The best digestion period was proved to be of 60 minutes in the experiment. The results indicate that stem cells with multilineage differentiation ability could be separated from adipose tissue, namely ADSCs.
