To establish a highly efficient plant regeneration system for wheat genetic transformation, the effects of three different concentrations of dicamba and two different sugar types on callus induction and plant regeneration from mature embryo cultures were evaluated. Callus induction and plant regeneration were obtained from mature embryos of two commercial cultivars Zhoumai 18 and Yumai 34 （Triticum aestivum L.） cultured on L3 basal medium. The results showed that the efficiency of mature embryo culture was significantly influenced by the genotypes, sugar types and dicamba concentrations. 4 mg L^-1 dicamba proved the best effective for inducing embryogenic callus and also gave the highest proportion of plants regenerated across the two cultivars. Substitution of maltose by sucrose significantly improved the plant regeneration efficiency in both cultivars. There was a significant interaction between genotype-by-sugar types, and sugar types-bydicamba concentrations. Overall, Zhoumai 18 gave the highest frequency of plant regeneration （82.65%） when dicamba concentration was 4.0 mg L^-1 and with sucrose in initial callus induction. These results will facilitate genetic transformation work with elite wheat.

Macrophages play an important role in inflammation, and excessive and chronic activation of macrophages leads to systemic inflammatory diseases, such as atherosclerosis and rheumatoid arthritis. In this paper, we explored the anti-inflammatory effect of broussonin E, a novel phenolic compound isolated from the barks of Broussonetia kanzinoki, and its underlying molecular mechanisms. We discovered that Broussonin E could suppress the LPS-induced pro-inflammatory production in RAW264.7 cells, involving TNF-α, IL-1β, IL-6, COX-2 and iNOS. And broussonin E enhanced the expressions of anti-inflammatory mediators such as IL-10, CD206 and arginase-1(Arg-1) in LPS-stimulated RAW264.7 cells. Further, we demonstrated that broussonin E inhibited the LPS-stimulated phosphorylation of ERK and p38 MAPK. Moreover, we found that broussonin E could activate janus kinase(JAK) 2, signal transducer and activator of transcription(STAT) 3. Downregulated pro-inflammatory cytokines and upregulated anti-inflammatory factors by broussonin E were abolished by using the inhibitor of JAK2-STAT3 pathway, WP1066. Taken together, our results showed that broussonin E could suppress inflammation by modulating macrophages activation state via inhibiting the ERK and p38 MAPK and enhancing JAK2-STAT3 signaling pathway, and can be further developed as a promising drug for the treatment of inflammation-related diseases such as atherosclerosis.

A novel zinc complex(ZnE) has been designed and synthesized based on the derivative of 2-(2’-hydroxyphenyl)-1-H-benzimidazole(HBI) and the neutral nitrogen-containing ligand(phen). The crystal of the title complex crystallizes in the monoclinic system, space group P2_(1)/n with a = 10.2631(2), b = 34.2166(6), c = 11.4103(3) A, β = 96.771(2)°, M_(r )= 844.24, V = 3978.99(14) A^(3), Z = 4, the final R = 0.0400 and wR = 0.1001 for 8107 observed reflections(I > 2σ(I)). In the title complex, the free protonated phenoxide moiety(4-OH) is successfully retained to realize pseudo-intramolecular hydrogen bonds with the coordinated O atom from the other ligand.

Objective:To explore the clinical characteristics,surgical treatment and prognosis of nonsmall cell lung cancer(NSCLC) among elderly patients over 80 ***:The clinical data,surgical methods,perioperative management,postoperative complications and prognosis of 52 NSCLC patients aged over 80 years were retrospectively ***:Out of 52 cases, 27 had a long-term smoking history(51.9%) and 44 were with other diseases(84.6%).Lobectomy was done in 32 cases(65.4%),sub-lobectomy in 20 cases(38.5%),including pulmonary wedge resection in 16 cases(30.8%) and lung segment resection in 4 cases(7.7%).The postoperative complication rate was 44.2%(23/52);the complication rate after lobectomy was 62.5%(20/32) and that after sub-lobectomy was 25%(5/20),with significant difference between lobectomy and sublobectomy (P0.05).Conclusions:Octogenarians with NSCLC are often afflicted with comorbidity, so perioperative management is more *** adhering to indications,surgery is still an important treatment of NSCLC patients over 80.
