Inflammasomes are multiprotein complexes that can sense danger signals from damaged cells or pathogens and assemble to mediate the activation of caspase-1, which proteolytically activates the proinflammatory cytokines IL-1β and IL-18.Uniquely, inflammasome activation needs two steps to induce inflammation.Its activation has been studied in human and different experimental liver diseases and demonstrated to have effects on hepatocyte damage, immune cell activation and amplification of liver inflammation.In this review, inflammasome and their functions in variant liver diseases (especially ALD, NASH, ischemia-reperfusion liver injury) will be discussed in detail.These findings could help us deepen our understanding about these diseases, and provide new clues to the therapy of them in clinical practice.

Objective To optimize the conditions of process for extraction of volatile oil of Rhizoma Zedoariae (RZ) in Weishu Granules and preparation of its ? - cyclodextrin- inclusion complexes. Methods Orthogonal design was adopted. Extraction content of RZ volatile oil was used as the index for the optimizing of extraction process. The amount of inclusion complexes and efficient inclusion rate served as the indexes for the optimizing of inclusion process. Ultraviolet spectrophotometry was applied to detect the content of volatile oil. Results The optimal extraction conditions were: gringding the crude RZ into coarse grains, adding 12- fold water and distilling the mixture for 6 h; the optimal inclusion conditions were: ? - cyclodextrin and volatile oil were mixed in the proportion of 8 :1, 2- fold water was added into the mixture and the mixture was triturated for 60 min. The maximum UV spectrum absorbance of aethylis acetas liquor of valatile oil located at wavelength of 253nm. Conclusion Higher extraction rate of RZ volatile oil can be achieved by this technique; volatile oil is powdered and its stability increased after being included by ? - cyclodextrin.

AIM: To investigate the efficacy of intravitreal ranibizumab combined with laser therapy in the treatment of macular edema caused by branch retinal vein occlusion ( BRVO) .
METHODS:There were 78 patients (78 eyes) who were diagnosed with macular edema caused by BRVO using fundus fluorescence angiography ( FFA ) and optical coherence tomography ( OCT ) . Group A: randomly selected 26 cases ( 26 eyes ) were given grid laser photocoagulation ( GLP) . Group B: randomly selected 26 cases (26 eyes) were given GLP first, and then received intravitreal ranibizumab 1wk later. Group C: randomly selected 26 cases ( 26 eyes ) undergone intravitreal ranibizumab first, and then given GLP 1wk later. There was no significant difference in macular edema. We analyzed the changes in the best corrected visual activity ( BCVA ) , central macular thickness ( CMT ) before and 1wk, 1,6mo after treatment.
RESULTS: Compared with before treatment, 1wk after treatment: mean value changes of BCVA and CMT were no significant difference in group A (P>0. 05);mean value changes of BCVA was improved and mean value of CMT was decreased in groups B and C, the difference was statistically significant (P<0. 05);BCVA and CMT changes between groups had statistical significance ( P<0. 01 );After treatment 1, 6mo:compared with before treatment, mean BCVA was improved in three groups, mean CMT was lower, the differences were statistically significant (P<0. 01);BCVA and CMT changes between groups were statistically significant ( P<0. 05 ); compared with 1mo after treatment, mean BCVA and CMT were no significant difference (P>0.05) between groups A and B after 6mo treatment;mean BCVA improved and CMT average value was decreased in group C, the difference was statistically significant ( P<0.01 ); BCVA and CMT changes between groups were statistically significant (P<0. 01).
CONCLUSION: Intravitreal injection ranibizumab combined laser therapy can effectively reduce BRVO induced macular edema, enhance vision acuity. Compared with GLP, combination therapy has more rapid onset of treatment, and reduce macular edema better; Intravitreal ranibizumab should be given in front of the GLP, and the treatment effect is more precise, more stability.

Objective To describe the MRI findings in patients with Acquired hepatiocerbral Degeneration(AHCD) and evaluate the role of MRI in dignosis of AHCD. Methods 26 patients with chornic hepatic failure under went brain MRI scan. Eight of these patients had abdominal MR digital subtract angiography(MRDSA) examnation. 25 patients had plasma ammonia levels test two weeks after MR exmnation. Results 22 patients had abnormal MRI findings, T 1WI demonstrated incresed signal in the globus pallidus (22/26), putmen (4/26), mesencephalon surrounding red nucleus(15/26),and in the anterior pituitary (12/26). While T 2WI demonstraied no corresponding alteration in signal intensity. Eight patients which had MRDSA showed obvious portal systemic shunts.

Total mRNA was extracted from lymphocytes separated from the peripheral blood of allergic patients, and then variable region of heavy chain (VH) and variable region of light chain (VL) cDNA library were constructed by RT-PCR. Human scFv templates for rabbit reticulocyte lysate ribosome display were assembled by primers and linker peptide (Gly4Ser)3. mRNA bound in antibody-ribosome-mRNA complexes was recovered using in-situ single primer RT-PCR, and three rounds of anti-IgE scFv DNA were enriched. The target DNA fragments were double enzyme digested and ligated into plasmid pET22b (+), followed by transformation in E. coli Rosseta (DE3). Positive clones were screened using clone PCR, Dot blotting and antigen ELISA. The correct lengths of VH (400 bp) and VL (710 bp) PCR products were obtained. The expected 1,000 bp ribosome display templates were also observed in agarose gel electrophoresis. After three rounds of ribosome display target sequences were effectively enriched, leading to a library of 10(13) members. Antibodies with the highest ELISA value for IgE were generated in the strain pET-IgE-6. A human anti-IgE scFv library was successfully constructed as described herein. Ribosome display using single primer in-situ RT-PCR as the recovery procedure effectively enriched target sequences. Anti-IgE scFv with high affinity and specificity were identified. The prepared human anti-IgE scFv fragment might be self-developed to a lead drug for treating asthma. Our study provides an alternative method for rapid discovery of human antibodies of therapeutic importance.

BACKGROUND: The gold nanoparticles have a killing effect on tumor cells.OBJECTIVE: To investigate the influence of gold nanochain on Hep-2 cells proliferation of human laryngeal carcinoma.METHODS: The gold nanochain was prepared by a glucose synthesis method and added into the culture cells with different concentrations (10%, 25%, 50%, 75%, 95%) to test the influence on proliferation of in vitro cultured Hep-2 cells. The endocytosis and exocytosis of transmembrane when gold nanochain attached to Hep-2 cells were observed by electron microscopy.RESULTS AND CONCLUSION: The gold chain at high concentrations (75%, 95%) exhibited inhibitory effects on the proliferation of Hep-2 cells, but the influence was not increased with increasing concentration, belonging to a range of non-toxic. Gold nanchain can enter into Hep-2 cells after 8 hours of co-culture and leave cells after 48 hours, indicating gold nanoparticles chain can enter and leave Hep-2 freely.

Objective To analyze the effect of intravenous dripping of 3% sodium chloride solution on prevention of diluted hyponatremia during transurethral vaporization of the prostate (TUVP). Methods Eighty-five cases with benign prostatic hyperplasia (BPH) accompanied with typical lower urinary tract symptoms (LUTS) were divided into two groups during undergoing TUVP operation: the control group(n=38) given Ringer's solution dripping (3ml/min) and the concentrated sodium chloride injection group(n= 47) given 3% sodium chloride solution dripping (2～4ml/min). All of the operations were taken via Wolf electric resection system, and the operation time was≥60 min. The complete blood count and serum electrolyte were determined before operation and 60 minutes after operation beginning, and the data were compared between the two groups. Results The decrease amplitude of serum sodium was obviously smaller in concentrated sodium chloride injection group[(1.45±5.14)mmol/L] than that in the control group[(7.79±6.64) mmol/L] 60 minutes after operation beginning (P<0.05). Conclusions Giving 3% sodium chloride solution by intravenous drip during TUVP may reduce the severity of diluted hyponatremia and postpone the occurrence of hyponatremia, and thereby decrease the risk of transurethral resection syndrome.
