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.

Objective To compare the changes of serum cystatin C(CysC),cytokeratin 19 fragment(CYfra21-1)and neuro-spe-cific enolase(NSE)levels before and after surgery in the patients with lung cancer.Methods ELISA and the chemiluminescence method were adopted to detect the levels of serum CysC,CYfra21-1 and NSE before and after operation in 33 patients with lung cancer and the detection results were compared with those in 35 health people.Results The serum CysC,CYfra21-1 and NSE levels in the lung cancer patients were significantly higher than those in the normal control group(P <0.01);which had statistically sig-nificant difference between before and after operation(P <0.05);the serum CysC,CYfra21-1 and NSE levels in 3 months after op-eration still had statistically significant difference compared with the normal people(P <0.05),moreover the serum CysC level was positively correlated with serum CYfra21-1and NSE levels(r =0.601 8,0.596 6,P <0.01 ).Conclusion Detecting serum cyscC, CYfra21-1 and NSE level change has certain clinical value for evaluating the prognosis and the disease condition monitoring of the patients with lung cancer.

Objective To study the surgical treatment of the primary retroperitioneal sarcoma(RPS). Methods The treatment and prognosis of 63 patients with primary retroperitoneal sarcomas (liposarcomas and leiomyosarcomas) from Jan 1992 to Dec 2000 were analyzed retrospectively. Results The rate of complete tumor resection was 88.2%, and concomitant resection of involved adjacent organs was 21.6%. There was no operation death. The median survival time(MST) in liposarcomas that for was 36.5months, and leiomyosarcomas was 27.6 months. The MST in highly differentiated tumor was 34.7 months,and that of intermiade and low differtiated tumors was 18.1months(P

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.

Objective To investigate the expressions of BMP-2 and bFGF in ankylosing spondylitis(AS)patients in active stage.Methods Five patients with active AS were admitted from July 2006 to March 2007,including 4 males and 1 female,with average age of 31.4 years.Five patients with pelvic fracture served as control,including 3 males and 2 females,with average age of 34.5 years.Using immunohistochemistry,the expressions of BMP-2 and bFGF were detected in the frozen synovial tissues of cacroiliac joint in active AS patients and in the pelvic fracture patients,and the results were compared by analyzing the gray scale of the pictures.Results The positive expressions of BMP-2 and bFGF in the synovial tissues of cacroiliac joint in the patients with active AS were stronger than those in pelvic fracture patients(P

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 catalogue for regular college programs is the guide to offering specialties and academic degrees in medical colleges and universities.It serves as the orienting framework under which to develop human resources at the institution of higher learning.Thus,it is an important task concerning the overall reform and development of tertiary education to revise the catalogue for regular college programs.This paper discusses the adjustment of such kind of catalogs in terms of their special aspects and distinctive qualities of medical education with an attempt to draw the attention of more experts and scholars to this research direction in order to ensure a stable,scientific,and continuous development of the catalog for medical sciences.

Objective To find a better method to reconstruct total ear in one stage. Methods In the procedure, a compound framework was formed, in which Medpor acted as ear framework and homogenous rib cartilage as helix-framework after being sculptured, then they were vamped together. The formed framework was covered with adjacent skin flap and homogenous skin graft after it had been covered with superficial temporal fascia flap. Results From January 2001 to Augest 2003, 8 cases of congenital microtia or antotia were treated in this way, and all of them obtained satisfactory appearance in auricle. Conclusion The reconstructed ear has a delicate structure and good appearance, and looks and feels as a real one by this new procedure.
