Hepatic carcinoma is one of the most common malignant tumors in China.Autophagy activity and the change of Nrf2-ARE pathway play an important role in the process of liver tumors.Nrf2 which is an important regulator to liver cancer belongs to the CNC family.Research discovered that after the inhibition of autophagy,Nrf2-ARE pathway activation contributes to the progression of hepatocellular carcinoma.This article summarizes the relationship between autophagy and the Nrf2-ARE pathway and its impact on the hepatic carcinoma.

Objective To summarize countermeasures on common problems of microendoscopic discectomy(MED). Methods Microendoscopic discectomy was performed in 104 cases of lumbar disc herniation by using the MED system(Sofamor Danek Group,USA).Frequently encountered problems during the operation were reviewed and summarized. Results Conversions to open surgery were required in 4 out of 104 cases due to bleeding or adherence.Among the rest of 100 cases,dural injury occurred in 3 cases,with 1 case accompanying leakage of cerebrospinal fluid.Of the 100 cases(115 intervertebral spaces),the average operation time was 50 min(range,30~90 min) and the average hemorrhage amount was 80 ml(range,20~400 ml) for each intervertebral space.The 100 cases were followed for 3~32 months(average,18 months).According to the Macnab criteria,the curative effects were classified as excellent in 65 cases,good in 29 cases,and fair in 6,the rate of excellent or good effects being 94.0%(94/100). Conclusions The most frequent problems during MED are bleeding and prolonged excision of the ligamenta flava.Strict adherence to technique,acquaintance with the weakness of the ligamenta flava,and familiarity with anatomic structures of the vertebral vein system and its relationship with abdominal pressure,are very important in the prevention and treatments of surgical complications.

T7 cDNA phage display method was employed to find the binding protein of PreSl protein. PreSl protein was coated in a 96-well ELISA plate, and then T7 cDNA library phages were bound to the target protein. Phages which did not bind to garget protein were washed away and the binding phages were eluted. Insertions from different clones were sequenced, and the deduced amino acid sequences were analyzed by Vector 6.0 software. Using BLAST software in GenBank, whole length of amino acid sequence of binding protein was obtained. After 4 rounds of biopanning, recombinant T7 phages with binding ablity were amplifed by infection to E. coli. One piece of amino acid sequence was found to be amino terminal of product of glioma tumor suppressor candidate region gene 2 (GLTSCR2). There was a binding domain KxPxKSGxxxL in these clones. T7 cDNA phage display technique can be used bo find the ligand. GLTSCR2 coding protein may be the binding protein to preSl protein of HBV.\;

Objective To explore the influence of HepG2 cells' proliferation and autophagy by the Nrf2-ARE pathway,and provide the experimental basis for clinical exploring effective liver cancer treatment.Methods Hepatic carcinoma HepG2 cells were cultured,and its proliferation inhibition rates and the change of cell cycle' s in each phase were explored by the MTT assay and flow cytometry.The hepatoma cells' autophagy was qualitative observed by inverted phase contrast microscope and fluorescence microscope.Results Inhibitory rate of HepG2 cells was obviously higher in the Nrf2 inhibitor BML-111 group than control group (P ＜ 0.05),and the control group was aslo obviously higher than the Nrf2 inducer EGb group (P ＜ 0.05).Flow cytometric analysis showed that G1 phase cells in the cell cycle increased,S phase cells reduced and G2/M period cells relatively increased in the Nrf2 inhibitor BML-111 group.But G1 phase cells reduced,S phase cells increased and G2/M period cells relative reduced in the Nrf2 inducer EGb group.Inverted phase contrast microscope and fluorescence microscope checked that ranging from the size of the bubble and autophagosome formed in Hepatoma HepG2 cytoplasmic of the Nrf2 inhibitor BML-111 group.Conclusions The Nrf2-ARE pathway played an reverse inhibition on HepG2 cells' proliferation and autophagy.After the inhibition of Nrf2-ARE pathway,HepG2 cells mostly stayed in the G1 phase of the cell cycle.

48 hours.The expressions of leukocyte common antigen(LCA) and intercellular adhesion molecule-1(ICAM-1) in the brain tissues collected during the surgery were detected by immunohistochemistry staining method.Results LCA and ICAM-1 immunopositive cells and microvessels were verified in all 29 cases of ICH groups,and the expressions were more than control group(all P48 hours group were higher than that in 6～24 h group(both P48 hours group.Conclusions Acute inflammatory reaction occurs in acute period of ICH.Expression of ICAM-1 reinforces gradually during early 48 hours since the onset of ICH.

Digestive tract reconstruction is an important part of gastric carcinoma operation as well as tumor resection and lymph node dissection.Surgeons are seeking the optimal reconstruction method that reduces the occurrence of complications and maintains better quality of postoperative life extremely.Uncut Roux-en-Y anastomosis is a modified procedure in which an artificial jejunal occlusion is devised to avoid Roux stasis syndrome based on Billroth Ⅱ and Braun's anastomosis.Compared to the conventional Roux-en-Y anastomosis,the uncut Roux-en-Y anastomosis retains the advantage of preventing biliary and pancreatic secretions reflux,furthermore,it can decrease the symptoms associated with Roux stasis owing to the abnormal myoelectrical conduction of Roux limb.Because the early studies indicated that there was higher incidence of dehiscence or recanalization of the jejunal occlusion,the uncut Roux-en-Y anastomosis has not been widely applied.Since jejunal occlusion has been optimized recently,the uncut Roux-en-Y reconstruction may be an optional and appropriate method of digestive tract reconstruction after distal gastrectomy.

Objective:To observe the influence of the “Warming yang and Nourishing qi” acupuncture treatment in the serum interleukin-12 (IL-12) and interleukin-18 (IL-18) expression levels,in the rats with experimental autoimmune myasthenis gravis (EAMG) and to analyze the mechanism of acupuncture treatment to myasthenis gravis (MG).Methods: AchRα1 129-145 peptide fragments were used to immune the female Lewis rats to establish EAMG rat models.30 successful EAMG model rats were randomly selected and divided into acupuncture treatment group ,drug control group and model control group ( n=10 );the unmodelled 10 rats purchased at the same period were used as blank control group.The rats in acupuncture treatment group were treated by “Warming yang and Nourishing qi” acupuncture treatment,30 min/time,once a day,7 d for a period,1 d rest between two periods,two periods of continuous treatment.The rats in drug control group were treated by the pyridostigmine lavaged treatment , 18.5 mg/( kg · d ) , continuous treatment of 15 d.The rats in the other two groups had no any special treatment.After treatment,the blood samples from the vein of tail root of the rats in 4 groups were collected ,and the serum expression levels of IL-12 and IL-18 were detected with ELISA method.Results:After treatment,compared with model control group ,acupuncture treatment and drug control group the serum IL-12 and IL-18 expression level of the EAMG rats were significantly decreased ( P<0.05 or P<0.01 ).Compared between acupuncture treatment group and drug control group showed that ,the serum IL-12 and IL-18 expression level of the EAMG rats were no significant difference ( P>0.05 ).Conclusion:“Warming yang and Nourishing qi” acupuncture treatment can reduce the serum IL-12 and IL-18 expression levels of EAMG rats to treat MG ,and the effect of treatment was similar to pyridostigmine.

Objective:To detect the modulation of the Th1/Th2 bias by the EtOH ext. of roasted perilla seed(RPS) in the anaphylaxis mice model.Methods:The mice were divided randomly into 5 groups, namely 1.28, 0.64 and 0.32 g/kg EtOH ext.of RPS group, anaphylaxis model and normal control. All the mice except for the normal control were sensitized by immunized intraperitoneally on days 0 and 5 with chicken OVA. The cytokine profile including IFN-?, TNF-?, IL-2, IL-4, IL-5 in serum of all the mice were evaluated by FCM.Results:The IFN-?/IL-4 ratio was decreased from 3.93 in the anaphylaxis mice model to 0.87 in the normal control group. The mice in 0.32, 0.64 and 1.28 g/kg EtOH ext of RPS group displayed a down-regulation for serum IL-4 and TNF-? levels and showed increased levels of IFN-? with the correspondent IFN-?/IL-4 ratio of 1.92, 2.85 and 3.14.Conclusion:The EtOH ext. of roasted perilla seed can modulate the Th1/Th2 bias in a dose-dependent manner.
