Polyvinyl alcohol terminal chemoembolization for hepatocellular carcinoma with hepatic arteriovenous shunts: Safety, efficacy, and prognostic factors.

Purpose: To evaluate the safety and efficacy of polyvinyl alcohol (PVA) terminal chemoembolization and to identify the prognostic factors associated with survival in hepatocellular carcinoma (HCC) patients with hepatic arteriovenous shunts (HAVS).

Materials And Methods: Of 133 patients' managements were retrospectively analyzed. HAVS was classified into three types: slow-flow, intermediate-flow and high-flow.

Percutaneous intratumoral injection with pingyangmycin lipiodol emulsion for the treatment of recurrent sacrococcygeal chordomas.

This study describes fluoroscopy-guided percutaneous intratumoral injection therapy (PIIT) with a pingyangmycin lipiodol emulsion in the management of recurrent sacrococcygeal chordomas after surgical excision. Seven patients underwent a total of 22 treatment sessions (3-4 sessions per patient); treatment responses were evaluated clinically, and lesion size was determined using computed tomography (CT). Over 10-26 months of follow-up, tumor sizes and visual analogue scale (VAS) scores of all patients were decreased.

[Removal of metallic foreign body in the soft tissue under fluoroscopy: 10 years of experiences].

Objective: To summarize our 10-year experience with percutaneous fluoroscopically guided removal (PFGR) of metallic foreign body (MFB) in the soft tissue.

Methods: PFGR was performed in 65 patients for removing a total of 368 MFBs from the soft tissues. The MFBs ranged from 0.

Necrosis and apoptosis in hepatocellular carcinoma following low-dose versus high-dose preoperative chemoembolization.

Our purpose was to study necrosis and apoptosis of hepatocellular carcinoma (HCC) cells after preoperative transcatheter arterial chemoembolization (TACE) with use of low-dose and high-dose anticancer drugs in HCCs. Fifty-four patients with advanced but surgically resectable HCC were studied. Thirty-four patients who elected to undergo preoperative superselective TACE were randomized to low- and high-dose TACE.

Effects of granulocyte colony-stimulating factor on repair of injured canine arteries.

Background: Endothelial progenitor cells (EPCs) derived from bone marrow may differentiate into endothelial cells and participate in endothelial repair. These cells can be mobilized into peripheral blood by cytokines, including granulocyte colony-stimulating factor (G-CSF). In the present study, we investigated the effects of G-CSF on neointimal formation and restenosis in a canine model of arterial balloon injury.

[Endovascular graft exclusion with digital subtraction angiography for treatment of Stanford type B aortic dissection].

Objective: To assess value of endovascular graft exclusion (EVGE) with digital subtraction angiography (DSA) in the treatment of Stanford type B aortic dissection (AD).

Methods: On the basis of diagnosis with multi-slice spiral CT (MSCT), DSA was performed in 20 Stanford B AD cases for further diagnostic confirmation and EVGE was conducted for treatment. The DSA findings of the cases and the therapeutic effect of EVGE were evaluated.

[Relationship of HepG2 cell sensitivity to continuous low dose-rate irradiation with ataxia-telangiectasia mutated phosphorylation].

Objective: To investigate the changes of ataxia-telangiectasia mutated (ATM) phosphorylation in HepG(2) cells in relation to HepG(2) cell survival under continuous low dose-rate irradiation.

Methods: HepG(2) cells were exposed to equivalent irradiation doses delivered at either a continuous low dose-rate (7.76 cGy/h) or a high dose-rate (4500 cGy/h), and the phosphorylated ATM proteins and surviving fraction of HepG(2) cells after the exposures were compared.

[Safety evaluation of iodine-125 seed implantation in rabbit liver tissue].

Objective: To evaluate the safety of iodine-125 seed implantation in the liver.

Methods: Twenty New Zealand rabbits were divided into control and treatment groups and in the latter, iodine-125 seeds of 37 MBq were implanted into the liver under CT guidance whereas nonradioactive seeds were implanted in the control rabbits. Four weeks after implantation, white blood cell count, liver functions, and renal functions were measured or evaluated for comparison with those before implantation.

[Percutaneous intradiscal oxygen-ozone injection for lumbar disc herniation: no need of perioperative antibiotic prophylaxis].

Objective: To evaluate the feasibility of no antibiotic administration to prevent infection during the perioperative period of percutaneous intradiscal ozone-injection for treatment of lumbar disc herniation.

Methods: Seventy-two patients with lumbar disc herniation but normal body temperature as well as normal results of three routine tests (blood, urine, stool) and C-reactive protein (CRP) level were randomly divided into two groups. The patients in prophylaxis group were given cephalothin V(2.

Value of angiography in the diagnosis of patients with small kidney.

Objective: To explore the diagnostic value of angiography in small kidney patients.

Methods: Angiographies were performed in 32 patients with small kidney of unknown etiology or with suspected renal arterial stenosis (RAS).

Results: Twelve cases of renal atrophy due to RAS were diagnosed by angiography, which demonstrated renal artery stenoses or occlusions.
