ABSTRACT
Objective To evaluate the rehabilitating effect of hyperbaric oxygen on visual pathway lesions with blood oxygen level dependent functional magnetic resonance imaging (BOLD-fMRI) and diffusion tensor imaging (DTI). Methods Sixteen patients with visual pathway lesions (the study group) and twelve healthy volunteers (the control group) were assessed using BOLD-fMRI and DTI. After hyperbaric oxygen therapy, the patients in the study group were again assessed using BOLD-fMRI and DTI. The activated regions of the BOLD-fMRI scan and the fractional anisotropy (FA) value determined from the DTI were calculated. Results Before hyperbaric oxygen treatment, there were significant differences between control and study groups in their BOLD-fMRI activated regions and the FA values of their radiation optics (P≤0.01). After hyperbaric oxygen treatment, there were no significant differences. Conclusion Combining BOLD-fMRI with DT1 could be used to evaluate the rehabilitation effect of hy-perbaric oxygen treatment in patients with visual pathway lesions.
ABSTRACT
20%),but turning negative with 3 of them after 3 weeks.All the transplanted kidneys revealed different degrees of atrophy but 4 of them obtained chances of successful retransplantation 3-6 months after the procedure,3 of them with follow up of 1-3 years were being well.Conclusions Renal arterial embolization is a safe,efficient measure for treating post-transplanted renal failure with obvious decrease of correlative clinical symptoms and providing conditions for renal retransplantation.
ABSTRACT
Objective To develop new-type multi-body-position tripod of X-ray appratus for field battle.Methods One screw was added to the bottom of axis stayer of the original tripod for the inversion of fixed bulb so that the bulb could vertically project.Three support feet were porlonged at the same time.Results The X-ray appratus of the new-type multi-body-position tripod could project for patients in satnding or lying position and the range of focus adjustmet was enlarged,which could meet nomal requirements.The new-added crew was firm and its support quality was greatly over the quality of X-ray appratus.Compared with the original one,the barycenter of the appratus was lower,and the hemline length was longer.It remaind portable for the overall quality and length didn't change apparantly.Conclusion The new-type multi-body-position tripod of X-ray appratus for field battle meets the practical field requirments.
ABSTRACT
The article of interventional therapy of hepatocellular carcinoma were reviewed including the method,basic research and the questions remained to be solved.All interventional therapies consisted of transcatheter arterial chemoembolism,transcatheter arterial heat infusion,transcatheter arterial heat embolism,Chinese medicinal herb,percutaneous ethanol injection,radiofrequencey ablation,percutaneous microwave coagulation and cryosurgery had their insufficiencies.The combined therapy,such as double chemoembolism,TACE combined with ablation,TACE combined with gene therapy could further promote the therapeutic effect.The research of the biological behavior of the residue after TACE was just at the beginning with problems still to be acknowledged.With the emerging of anti-oncogene therapy(P 53)and oncolytic virus therapy represented the gene therapy,together with anti-angiogenesis therapy,now the interventional therapy for hepatocellular carcinoma steps in a new stage.The treatment of during and perioperative periods possesses a great correlative influence with the therapeutic effect and complications and should be further standardized.
ABSTRACT
Objective To study the efficacy,safety and correlative characteristics of Chinese herb as a vascular embolization agent.Methods Vascular embolization agent combined from several kinds of Chinese herb was manufactured and served as anticarcinogen and coagulant according to the chinese Pharmacopeia.The characteristics of the combination embolization agent through embolizing the hepatic arteries in eight pigs were studied. Results The combination agent was a non-homogenous suspension,easily to be injected through 5-F catheter with hyper attenuation under fluoroscopy;simultaneously with good histocompatibility and hemo-compatibility and without feverish response and toxicity.The combination agent mainly embolized the peripheral arteries with maintaining occlusion for 5 weeks and without formation of collateral circulation.Slight injuries of normal hepatic tissues with hepatic cytonecrosis and endochyloma focal necrosis were found through optical and electronic microscopy.Conclusions The Chinese herb combination agent is safe and effective in experimental application with good angioembolic function and a potential peripheral embolization agent.
