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.

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.

This study was aimed to investigate effect on the expression of cell inflammatory factor IL-1α, IL-1β and IL-6 of modified San-Jia-San (SJS) decoction on cultured hippocampal neurons injury induced by β-amyloid 25-35 protein (Aβ25-35). Primary cultured hippocampal neurons were divided into the normal group, model group, huperzine A group, low-dose SJS group, middle-dose SJS group, and high-dose SJS group. After selective culture for 7~10 days and the absorption of culture fluid, the blank culture fluid, normal cerebrospinal fluid (normal saline group), huperzine A cerebrospinal fluid, and low-, middle- and high-dose SJS cerebrospinal fluid were added, respectively. The culture fluid was added up to an equivalent medium. The incubation was 2 h under the temperature of 37℃. Ex-cept the normal group, Aβ25-35 dealt with aging (the final concentration was 5 μmol/L) was added to other groups to establish AD cell model. An equivalent amount of culture fluid was added to the normal group. After 24 h of incuba-tion, the cell culture supernatant was collected. Enzyme-linked immunosorbent assay (ELISA) was used in the content detection of IL-1α, IL-1β and IL-6. The results showed that modified SJS decoction can decrease the content of IL-1α, IL-1β and IL-6 in the cell culture supernatant. It was concluded that the modified SJS decoction can effectively inhibit the expression of cell inflammatory factor IL-1α, IL-1β and IL-6. It had certain anti-inflammatory effect to protect hippocampal neurons.

Objective To investigate the effect of exercise preconditioning on serum level of tumor necrosis factor α (TNF-α), interleukin (IL) -1β and IL-6 in rats after cerebral ischemia-reperfusion (I/R). Methods 24 male Sprague-Dawley rats were randomly divided into exercise preconditioning group (n=8), model group (n=8) and sham group (n=8). The middle cerebral arteries were occluded for 120 min and re-perfused. All the rats were evaluated with neurological deficit score 2 hours, 24 hours after I/R. The serum levels of TNF-α, IL-1β and IL-6 was detected with enzyme-linked immunosorbent, and the pathology was observed with HE staining 24 hours after I/R. Results The neurological deficit score decreased in the exercise preconditioning group compared with that in the model group, as well as the serum TNF-α, IL-1β and IL-6 (P<0.05) 24 hours after I/R. The pathological damage and interstitial edema alleviated in cerebral ischemia cortical, and the degeneration and necrosis of the neurons in the ischemic area significantly reduced in the exercise preconditioning group. Conclusion Exercise preconditioning may inhibit inflammatory response in I/R rats to protect neurological function from impairment.
