Objective To investigate the selection and effectiveness of interventional treatment for different types of Budd-Chiari syndrome (BCS). Methods A total of 138 cases of BCS were divided into 4 types (type Ⅰ, membranous stenosis and obstruction of the inferior vena cava; type Ⅱ, segmental stenosis of the inferior vena cava; type Ⅲ, segmental obstruction of the inferior vena cava; type Ⅳ, patent inferior vena cava) and 9 subtypes according to results of angiography of the hepatic vein or the inferior vena cava. Therapeutic methods included percutaneous transluminal angioplasty (PTA) of the inferior vena cava and stent placement by way of the femoral vein, right cervical vein or subclavian vein, and PTA of the hepatic vein by way of the transhepatic approach, right cervical vein or inferior vena cava. Results The success rate was 100% (83/83) in type Ⅰ patients, 75.0% (9/12) in type Ⅱ patients, 81.6% (31/38) in type Ⅲ patients, and 60% (3/5) in type Ⅳ patients. One patient died (0.7%, 1/138). Complications occurred in 4 patients (2.9%, 4/138), including 2 cases of pericardial injury, 1 case of stent detachment, and 1 case of hepatic hemorrhage. Follow-up observations in 126 successful cases for 3~96 months (mean, 26 months) showed 8 recurrent cases, 2 of which expired, and 2 fatal cases because of hepatocarcinoma. Conclusions Interventional therapy, as a simple, safe and effective minimally invasive method, is the first choice for the treatment of BCS.

Aim To study the mechanism of curcumin induced U251 cell apoptosis. Methods U251 cells were treated with 20～100?mol?L~ -1 curcumin for 24 h and the growth inhibition rates of U251 cells were measured with MTT method. MTT method was used to measure the caspase inhibitors effect on curcumin too. Cell apoptosis was inspected with flow cytometry (FCM) and observed using electron microscope. The protein levels of FAK in U251 cells were observed by SP immunocytochemistry. The activity of caspase-3 was measured by spectrofluorometry. Results Curcumin inhibited the proliferation of U251 cells,induced apoptosis of U251 cells. At the same time the protein levels of FAK in U251 cells decreased and the activity of caspase-3 increased significantly. The apoptosis of U251 cells was partially reversed by caspase inhibitors. Conclusion Curcumin induced apoptosis via inhibition of expression of FAK and activation of caspase-3.

Conclusion The CaTiO3 coating on titanium is neither mutagenic nor hemolytic and has no toxicity on osteoblasts .Instead, it can promote the proliferation of osteoblasts , and therefore is a valuable coating material for implants .

Objective To prepare the acellular scaffold of spinal cord and analyze its component.Methods The acellular scaffold was prepared with the freeze thawing and chemical extraction,its structure was observed by HE and SEM,its component was analyzed by immunohistochemistry.Results The cells,myelin sheath and axon of nerve fibers in the rat spinal cord were eliminated,but three-dimensional supports of extracellular matrix were reserved.The analytical results showed the component of the acellular spinal cord contain laminin,fibronectin and type Ⅳ collagen—the necessary components to facilitate and induce the regeneration of the injured nerves and enhance the adhesion and proliferation of cells.Conclusion The acellular spinal cord has three dimensional structure and contains several proteins related to the regeneration of the injured nerves and promotion of the survival and proliferation of cells.

Objective To investigate the effects of transplantation of oligodendrocyte precursor cells(OPCs) on the recovery of neural function in rats with spinal cord injury.Methods The spinal cord injury(T10) rat model was established by Allen's method of weight-drop injury.Ninety six SD rats were randomly divided into 4 groups(24 each): transplantation group,control group,injury-only group and sham-operation group.Seven days after spinal cord injury,the rats of transplantation group received OPCs transplantation,of control group were injected with equivalent saline,and of injury-only group were untreated.The effects of OPCs transplantation on neural functional recovery in spinal cord injured rats were measured by the behavioral test and assessments of motor evoked potentials(MEP) and somatosensory evoked potentials(SEP).Results Immediately after spinal cord injuries,the neural function of spinal cord of rats was markedly impaired.The results of behavioral test,MEP and SEP in injured rats were much worse than those in sham-operation group.Although the neural function in spinal cord injured rats improved in different degrees with the time,the results of behavioral test,MEP and SEP showed it was significantly better in transplantation group than that in control group.Conclusion The transplantation of OPCs may enhance the recovery of neural function of rats with spinal cord injuries.

Objective: To study the protection of IL 1ra in cultured developing neuron injury following Mg 2+ free induced epileptiform discharges. Methods: Rat embryo cortical neurons cultured for 6 d and 17 d were directly exposed to Mg 2+ free media, or pretreated with IL 1 receptor antagonist or NMDA receptor antagonists before being exposed to Mg 2+ free media, and then returned to regular media.MTT assay was used to study mitochondrial function injury, laser scanning confocal microscope to measure [Ca 2+ ]i, and real time RT PCR to detect gene mRNA expression. Results:(1) MTT conversion rates were higher in neurons pre and co treated with 10 mg/L IL 1ra than those of neurons with only Mg 2+ free treatment in neurons cultured for 17 d, but not in neurons cultured for 6 d.(2) [Ca 2+ ]i was lower in neurons pre and co treated with 10 mg/L IL 1ra than those of neurons with only Mg 2+ free treatment, either in neurons cultured for 6 d or in neurons cultured for 17 d, and the effects of IL 1ra on [Ca 2+ ]i change were different between neurons cultured for 6 d and neurons cultured for 17 d.(3) Pre and co treated with 10 mg/L IL 1ra NR1 mRNA expression increase induced by Mg 2+ free treatment was decreased, either in neurons cultured for 6 d or neurons cultured for 17 d, and this effect showed no difference between neurons cultured for 6 d and 17 d; Pre and co treated with 10 mg/L IL 1ra NR2A mRNA expression increase induced by Mg 2+ free treatment in neurons cultured for 17 d was decreased, and NR2A mRNA expression showed no difference between IL 1ra group and age matched control group, but have no effect on neurons cultured for 6 d; Pre and co treated with 10 mg/L IL 1ra have NR2B mRNA expression increase induced by Mg 2+ free treatment was not affected, either in neurons cultured for 6 d or neurons cultured for 17 d. Conclusion:Neuroprotection of IL 1Ra in seizure induced injury is age dependent. The mech anism of the neuroprotection of IL 1Ra includes down regulation of [Ca 2+ ]i and others.

Microbiome is a novel research field related to human health,agriculture,bio-energy and the environment. Gut microbiome has received much attention from researchers recently. Studies have shown that gut flora is related to some diseases,such as digestive disease(inflammatory bowel disease),metabolic disease(type 2 diabetes), cardie-cerebral vascular disease(Parkinson disease). Traditional Chinese materia medica(TCMM) has long been used as a tonic and taken in a large amount. Gut flora has an effect on pharmacology and toxicology of TCMM after entering the gastroin?testinal tract. This article is intended to review recent researches on microbiome,common detection techniques and the relationship with hepatotoxicity induced by Polygonum multiflorum Thunb.,scutel?laria baicalensis that directly affects the intestinal tract,nephrotoxicity induced by Rhizoma Alismatis and pneumonia induced by Xiao-Chaihu-Tang.
