Objective To investigate the multi spiral CT findings of ovarian endometrioid adenofibroma.Methods The clinical and CT imaging data of 7 patients with ovarian endometrioid adenofibroma were retrospectively analyzed,and the characteristic CT findings were summarized.Results All 7 patients of ovarian endometrioid adenofibroma in this group were unilateral,with tumors presenting as round or lobulated masses.Most cases were cystic-solid lesions.The density of cystic fluid was higher than that of water or urine,and fibrous septa of varying thickness were visible.Enhanced scanning showed solid part and fibrous septa with moderate enhancement.Conclusion The CT findings of ovarian endometrioid adenofibroma have certain characteristics,measuring the density of cystic fluid and enhancing scanning can improve it's diagnostic accuracy.

Objective To investigate the adhesion molecule expression and functional status of platelets in lung cancer patients, and their relations with disease progression. Methods Using flow cytometry to measure the expression of surface antigens and functional status of platelets in 60 healthy control group, and 164 lung caneer patients. Results Comparing with control group, the expression in early group and mid term group(A group) of CD31, CD36, CD62, CD63 increased, and there is no significant meaning in the differences of surgery group (B group) of CD31, TSP, CD36, CD62, CD63. The expression in advanced group (C group) of CD31, TSP, CD36, CD62, CD63 increased. Comparing with A Group, the expression in B Group of CD36, CD62, CD63 decreased. The expression in C group of CD31, TSP, CD36, CD62, CD63 increased. Comparing with the small cell lung cancer, the expression of adenocareinorna of TSP, CD36,, CD62, CD63, squamous cell carcinoma of CD31, CD62, CD63, and alveolus cancer of CD31, TSP, CD63, all decreased. Conclusion The high level expression of platelet activation exists in patients with lung cancer of different stage, and decreased after operation. Platelet activation expressed significantly in the advanced stage of small cell lung cancer.

The porous foams were prepared by the solvent-casting and particulate-leaching technique using poly(DL-lactide) (PDLLA), poly(DL-lactide)/hydroxyapatite (PDLLA/20wt%HA), and poly(DL-lactide)/beta-tricalcium phosphate(PDLLA/20wt% beta-TCP) respectively. Observations by scanning electron microscopy indicated that the HA and beta-TCP were homogeneously dispersed in the polymer matrix, and the pores of the foams are interconnected, resulting in continuous pore structures. The porosity of PDLLA/HA and PDLLA/beta-TCP foams was lower than that of the pure PDLLA foams, but the compression strength was higher than that of the pure PDLLA foams. The results of the degradation in vitro showed that both HA and beta-TCP had significant inhibitory effects on the degradation of PDLLA, especially the HA. It is expected that the composite foams are of use as scaffolds for bone tissue engineering.
