Journal of Interventional Radiology 2006;0(12):-
Objective To evaluate the diagnostic angiography and interventional therapy for the different acute massive hemorrhage of abdomen. Methods 80 cases of acute hemorrhage of abdomen and pelvis with clinical data of selective arteriography and endovascular interventional therapy were collected and analized retrospectively. Seldinger technique was adopted for selective visceral angiography via femoral approach with lipiodal, gelfoam and spring coils as the embolic materials. Results All bleeding sites in 80 cases could be confirmed and 68 cases of them were successfully embolized, 9 cases occurred with rehaemor- rhagia and 3 cases were ineffective. Conclusion Interventional therapy not only ascertain the bleeding site, but also stop bleeding. The effect is certainly positive.

Early lymph node metastasis is a common clinical phenomenon in many human cancers, which is associated with both aggressive disease and poor prognosis. Clearly, treatments to specifically block dissemination through the lymphatic network would be desirable either as independent therapies or as adjuncts to existing chemotherapy. At the present stage the target vessels for invasion by lymph-metastasizing tumor cells include preexisting tissue lymphatics abutting the tumor mass through either coincidence or mutual chemoattraction, as well as new lymphatic vessels that proliferate either within or around the tumor as a result of lymphangiogenesis. The lymphangiogenesis is regulated primarily by the lymphangiogenic growth factors VEGF-C and VEGF-D generated by tumor cells or host cells including tissue macrophages. Nevertheless, it remains controversial as to whether this metastasis-enhancing effect simply results from an increase of the number of target vessels due to mitogenesis or from other properties of the newly dividing tumor lymphatics.

The histological and biomechanical aspects of the osteogenesis in metaphysioto-my lengthening of the tibia were observed in 45 immature rabbits,which were divided into 3 groups as follows:(1)Group A:After metaphysiotomy,the periosteum and endosteum of the transected boneends were well-preserved.(2)Group B:After metaphysiotomy,the periosteum about 0.7 cm in width on the 2 bone ends was circumcised.Then the 2 bone ends were aligned without disturbing the endosteum.(3)Group C:After metaphysiotomy,a part of the bone marrow and endosteum in the 2 bone ends wwere removed.Then the 2 bone edns were well aligned and the periosteum was sutured up.In all the experimental animals,the tibia was lengthened by 1mm/day.It was found that in Group A,the formation and remodelling of the new bone in the lengthened area occurred quite early after metaphysiotomy and the new bone was good in its biomechanical quality;in Group B,the formation of new bone was retarded and the biomechanical quality of the new bone was not satisfactory;and in Group C,new bone formation was sluggish in the early stage after metaphysiotomy but it wwas active in the late stage,and the neww bone formed was similar to that of Group A in its histological morphology and biomechanical quality.The periosteum could grow synchronously with the slow traction without any tearing.In addition,osteotomy and mechanical traction could stimulate and accelerate periosteal osteogenesis.It is believed that an intact periosteal cuff is of significance in the osteogenesis of the lengthened area since it serves as a restriction framework for the adherent growing of the connection between the new bones of the 2 bone ends and periosteal osteogenesis plays a more important role than endosteal osteogenesis in the bony healing of the lengthened area.

Circulating tumor cells (CTCs) are cancer cells shed from tumor into blood circulation. These cells are valuable in micrometa-static detection, disease assessment, and therapy and prognosis prediction of tumors. However, the clinical application of CTCs pro-gresses slowly due to its rarity in the blood and difficulty for detection. Given the development of biological techniques, scholars have developed several new methods for enrichment and detection of CTCs. Aptamer-based method shows a good prospect in CTC applica-tion. In this method, CTCs can be rapidly and efficiently captured, nondestructively released, and qualitatively and quantitatively ana-lyzed. This method can also be used to detect single and sub-groups of CTCs.
