Cervical spondylotic myelopathy (CSM) is a common cause of spinal cord dysfunction clinical disease. Surgery is the main therapeutic tool for CSM. However, there are obvious differences in clinical functional recovery after operation. For the past few years, the influence factors of prognosis in cervical spondylosis myelopathic has been widely concerned. Age, nerve function, course of desease, imaging findings,surgical method and related factors became the investigative point for prognosis of cervical spondylotic myelopathy. Present viewpoint showed that the older patient, preoperative worse nerve function, longer the course of disease would result in worse outcomes. Imaging examination maybe can indicate the prognosis, but the correlation is unclear. Selection of surgical method and approach should be based on the principles of sufficient decompression, stabilize the alignment of the cervical spine, keeping backward extension of cervical spine, maintain effective decompression, preventing complications. Therefore, the treatment of cervical spondylotic myelopathy should be on the basis of pathogenic condition and imaging examination at early stage and a suitable usrgical procedure should be performed to obtain a better prognosis.

Objective To investigate the dose and time kinetics of induction of apoptosis induced by doxorubicin in J urkat leukemiacells, and to explore its pertinent molecular mechanisms. Methods Human Jurkat leukemia T - cells were treated with doxorubicin at theconcentration of 0.1 mg/L, 0.2 mg/L, 0.5 mg/L and 1.0 mg/L for 6,12,24 and 36 hours, respectively, of which one sample was pre-treated with zVAD- fmk (benzyloxycarbonyl - Val -Ala - Asp - fluoromethylketone) prior to addition of doxorubicin 0.2 mg/L. Apop-tosis was detected with both annexin V - FITC and propidium iodide ( PI ) staining and annexin V FITC and PI double positive cellswere analyzed by flow cytometry. Western blot was used to evaluate the level of Fas ligand (FasL) and FADD (Fas - associated death do-main) expression. Results The differences of apoptotic cells induced by all dose of doxorubicin were not significant (P＞0.05 ) at 6hour;at 12 hour, only the highest dose, 1 mg/L, significantly induced cell apoptosis;while the lowest dose,0.1 mg/L, did not significantlycaused cell apoptosis for all time points. After exposure to the doses of 0.2 and 0.5 mg/L for 24 or 36 hours,a significant increase in per-centage of apoptotic cells was observed (P ＜ 0.001 ). Apoptosis induced by doxorubicin was completely inhibited when the cells were incu-bated with doxorubicin in the presence of zVAD - fmk (P ＜ 0. 001 ). The level of FasL and FADD expression correspondingly increasedwith exposure time to doxorubicin. Conclusions Doxorubicin induces apoptosis in a dose - and time - dependent manner; upregulatedFasL may initiate the activation of the Fas signaling pathway and caspases are the ultimate executioner in the induction of leukemia cellapoptosis by doxorubicin.

OBJECTIVETo investigate the clinical value of digital subtraction angiography (DSA) and interventional treatment in gastrointestinal arterial hemorrhage.

METHODSDSA data and experiences of interventional treatment of 78 cases with gastrointestinal arterial hemorrhage were retrospectively analyzed.

RESULTSThe positive rate of DSA diagnosis was 74%(58/78). Contrast media overflow direct sign was found in 33%(26/78) patients. Contrast media overflow direct sign of postoperative anastomotic stoma was found in 83%(15/18) patients. Hemorrhage causes of 15 cases were duodenal ulcer, 5 stomach ulcer, 2 gastric cancer, 1 Dieulafoy disease, 9 vascular malformation and dysplasia, 8 in anastomotic stoma bleeding after gastrointestinal operation, 10 hepatic artery blow out and bleeding after operation of liver disease, 5 Crohn disease, 6 intestinal tract diverticulum hemorrhage, 6 enteritis or ulcer and 3 polyp of small intestine, 1 midrange malignant small intestinal interstitial tumor, 2 well differentiated small intestine leiomyosarcoma, 5 colon and rectal cancer. Fifteen cases received arterial drug infusion and 36 received arterial embolization. Twenty-seven cases underwent operation after DSA and interventional treatment, whose coincidence with pathology was 78%(21/27). Technical success rate of arterial embolization was 86%(31/36) and clinical success rate was 72%(26/36). Technical success rate of arterial drug perfusion was 60%(9/15) and clinical success rate was 40%(6/15). Rebleeding rate was 16%(8/51) after intervention treatment. During follow-up for 2-36 months, 1 rebleeding patient received gastroscope treatment after embolization, but failed and died later. There were no severe complications,such as ischemic necrosis,in all the cases.

CONCLUSIONDSA is very important for the location and qualitation of gastrointestinal arterial hemorrhage. Transarterial drug infusion and embolization are safe and effective, and available to selective operation and complication handling.

BACKGROUNDOsteosarcoma is characterized by high neovascularization and a high propensity for metastasis through bloodstream. This study was to examine whether there is evidence for vasculogenic mimicry in osteosarcoma and to illustrate mechanism of tumor blood vessels formation in osteosarcoma.

METHODSOsteosarcoma cell lines (U-2OS) were tested for their ability to form tubular networks in three-dimensional culture containing type I collagen. The structures of the tubular networks were observed with phase contrast microscope and transmission electron microscope (TEM). Morphometric studies using hematoxylin and eosin (HE) stain and CD31 immunohistochemical stain to show tumor-lined channels in human osteosarcoma were also performed.

RESULTSObservation with light microscope and TEM showed that highly aggressive osteosarcoma cell lines (U-2OS) formed networks containing channels when grown in three-dimensional culture containing type I collagen, in the absence of endothelial cells or fibroblasts. Morphometric observation using HE stain and CD31 immunohistochemical stain showed that tumor cell-lined channels were also detected in vivo in osteosarcoma; by comparison, all vascular areas in the pedicle of osteochondroma or outside osteochondroma were endothelial-lined.

CONCLUSIONThese observations strongly suggest that aggressive osteosarcoma cells may generate vascular channels that facilitate tumor perfusion independent of tumor angiogenesis and have the ability of vasculogenic mimicry.
