BACKGROUND:Expanded polytetrafluoroethylene is a kind of porous polymer materials which is commonly used as clinical implants, and it has good biocompatibility, and is not easy to deformation or metamorphism. There is no existence of inflammation absorption reaction, and it al ows the cel migration and tissue ingrowth.
OBJECTIVE:To study the biocompatibility of expanded polytetrafluoroethylene scaffold and human adipose-derived stem cel s.
METHODS:The passage 4 human adipose-derived stem cel s were co-cultured with expanded polytetrafluoroethylene scaffold in vitro. The morphology and function of cel s adhered to the scaffold were observed by inverted phase contrast microscope, and cel adhesive rates and proliferation rates were also calculated by MTT assay.
RESULTS AND CONCLUSION:The inoculated cel s were round and bright, distributed on the surface of scaffolds uniformly, with good cel viability. After 3 hours a large number of adherent cel s were observed from the micrograph;after 24 hours there were a smal amount of short-spindle adipose-derived stem cel s. After cultured for 3 days, the short fusiform or polygon cel s could be seen clearly. After cultured for 7 days, the number of cel s increased significantly, few cel s fel off from the scaffold, and cel adhesion rate was up to an average of 95.7%. Meanwhile, the cel s revealed normal splitting proliferation rate. These findings indicate that human adipose-derived stem cel s are able to attach, grow and proliferate wel on the scaffold. Expanded polytetrafluoroethylene reveals excel ent cel ular compatibility and can be used as a vehicle for adipose tissue engineering.

BACKGROUND:The establishment of a good blood supply is a key mechanism for successful implantation of engineered tissues. OBJECTIVE:To observe the effect of basic fibroblast growth factor on the migration of human adipose-derived stem cells via implanting the human adipose-derived stem cells and sodium hyaluronate composite graft at the subcutaneous site of BALB/C mice, in order to explore an optimal scheme for soft tissue reconstruction. METHODS:Human adipose-derived stem cells were isolated from the adipose tissue of healthy cosmetic patients which received liposuction, and the cells were subcultured. Then 5×109/L passage 3 cellsuspension labeled by cm-dil was prepared. The working solution containing 2 mg/L basic fibroblast growth factor was prepared. Composite tissue al-lografts which were the mixtures of 0.25 mL sodium hyaluronate, 0.2 mL cellsuspension and 0.05 mL working solution or DMEM were implanted into the subcutaneous site of both sides of the mouse back. Specimens were taken at 6 weeks after operation and were evaluated histological y after hematoxylin-eosin and vascular immunofluorescent staining. RESULTS AND CONCLUSION:No necrosis, liquefaction, nodular tissue or gel remained in operated position. The hematoxylin-eosin staining showed the main components of the specimens were the adipose tissue and the loose connective tissue. The immunofluorescence staining showed the overlaps between the cm-dil fluorescence from human adipose-derived stem cells and the FITC fluorescence from the vascular endothelium in the experimental group were more than those in the control group (P<0.05). Basic fibroblast growth factor promotes the migration and the differentiation of human adipose-derived stem cells in the sodium hyaluronate scaffold into vascular endothelium.

Objective To preliminarily discuss the technical points and clinical efficacy of the pressure cooker technique (PCT)for embolization of intracranial arteriovenous malformation (AVM). Methods From April 2015 to May 2015,7 patients with AVM were treated at the Department of Neurosurgery, Shanghai Deji Hospital. The AVMs of 2 patients were embolized with PCT. (both were Spetzler-Martin gradeⅡ). A sonic and an echelon microcatheter were implanted side by side into the same blood supply artery of an AVM. A coil + α-isobutyl cyanoacrylate (NBCA)plug was formed between the sonic microcatheter tip and the detachable point through the echelon microcatheter in order to prevent Onyx reflux when the glue was injected into a nidus via a sonic microcatheter,achieving the embolization effect of sustained,rapid and high efficient. Results Two patients achieved complete embolization immediately. The symptoms of the patients improved or disappeared within 1 month. The whole brain DSA showed the AVM of one patient did not have recurrence at 4 month after embolization. Two patients did not have any complications or sequelae at the follow-up study. Conclusion PCT can improve the efficiency of embolization. It is suitable for small, medium,superficial,non-major functional area,less feeding artery AVMs,and AVMs with less blood flow in nidus. Its safety and clinical effect still need to be observed with more samples.

Chronic hepatitis B(CHB)is one of the most commom cause of liver fibrosis. Accurate assessment of liver fibrosis is essential for the strategy of treatment and judgement of prognosis . Liver biopsy is the gold standard for staging fibrosis,but it is invasive with high cost,low reproducibility and poor acceptance by patients. Therefore,it is urgent to explore a noninvasive modality for the assessment of liver fibrosis. Recent evidence highlights that elastographic techniques, biochemical markers and the diagnostic model consisted of several serum markers have the potential for the diagnosis of liver fibrosis. This article reviewed the progress in noninvasive assessment of liver fibrosis in patients with CHB.
