[Styloid process syndrome: report of 72 cases].

Objective: To investigate the correct diagnosis for styloid process syndrome.

Method: CT scan and 3D reconstruction was undertaken in 301 cases with foreign body sensation in submandibular angle, pain in pharyngeal, tension feeling and unhealing feeling after tonsillectomy. 263 cases were diagnosed as styloid process syndrome.

[MSCT perfusion analysis of nasopharyngeal cancer].

Objective: To study MSCT perfusion imaging of nasopharyngeal cancer and its differentiated diagnosis.

Method: Thirty cases with nasopharyngeal cancer performed multi-detector CT perfusion examination. Among them, there were 6 cases of 25 post-radiotherapy patients performed perfusion imaging with CT scan.

[Different adhesion rate of sheep BMSCs on copolymers of 3-hydroxybutyrate and 3-hydroxyvalerate before and after photografting modification in vitro].

Objective: To evaluate the biocompatibility of the sheep BMSCs cultured on the surface of photografting modified copolymers of 3-hydroxybutyrate and 3-hydroxyvalerate (PHBV).

Methods: BMSCs were isolated from bone marrow of the posterior iliac crest of a 6-month old sheep by whole marrow adherent culture method. The 3rd passage BMSCs were seeded onto modified PHBV and conventional PHBV films, or three-dimension scaffolds.

Comparative analysis of serum proteomes: discovery of proteins associated with osteonecrosis of the femoral head.

No means exist to evaluate the activity status, turnover, and prognosis of idiopathic osteonecrosis of the femoral head (IONFH) except for X-ray evidence of segmental collapse as a very good marker for prognosis. Moreover, the only current method for diagnosis of this disease is through physical examination and diagnostic imaging results, and no serum biochemical markers exist. A comparative analysis of serum proteomes was performed to discover proteins associated with osteonecrosis of the femoral head.
