    Abstract Objective: Arginine improves healing and modulates inflammation and the immune response. This systematic review aimed to assess the effect of arginine-enriched enteral formulas in pressure ulcer (PU) healing.
    Method: Systematic computerised searches of PubMed, Web of Knowledge, Scopus, ENTRAL and CINAHL databases were performed from their inception to 20 January 2016. Randomised controlled trials (RCTs) were included in this systematic review. We used the Jadad scale as a quality assessment tool.
    Results: There were seven RCTs with 369 patients included in this systematic review; four RCTs assessed healing by PU area reduction. All of them reported arginine-enriched enteral nutrition led to a significant improved PU healing compared with standard hospital diet in 2-12 weeks follow-up. Among these four RCTs, one enrolled malnourished patients, one enrolled non-malnourished patients, and the other two studies did not restrict the nutritional status of the patients. Using the Pressure Ulcer Scale for Healing (PUSH) four RCTs assessed healing of PU, all reporting arginine-enriched enteral nutrition resulted in a significant PUSH score improvement compared with control at follow-up. Using the Pressure Sore Status Tool (PSST) one RCT assessed healing of PUs, finding patients receiving arginine had the lowest PSST scores compared with controls. An RCT compared healing with two doses of arginine (4.5g versus 9g), but no difference was found between the doses.
    Conclusion: Evidence showed that arginine-enriched enteral nutrition led to a significant improvement in PU healing. It was effective not only in malnourished patients, but also in non-malnourished patients.

    Abstract Gastric cancer (GC) is the fourth leading cause of gynecological malignancies worldwide. 5-fluorouracil (5-FU)-mediated chemotherapy is the adjuvant treatment for patients with GC following surgical resection. Many studies have indicated the cancer-type specific roles of forkhead box protein A1 (FOXA1) and keratin 7 (KRT7) in human malignancies. However, the potential mechanism underlying the involvement of FOXA1 and KRT7 in the pathogenesis and chemoresistance of GC are still not entirely clear. In our study, gain- and loss-of-function experiments proved that FOXA1 promoted cell proliferation, migration and invasion in AGS and SGC-7901 cells. Consequently, KRT7 was identified to be transcriptional activated by FOXA1 using Dual luciferase reporter assay. Our results also indicated that FOXA1 exerted its functions in enhancing viability and invasion of AGS and SGC-7901 cells through activating KRT7. Finally, interference of FOXA1 or KRT7 increased the chemosensitivity of AGS and SGC-7901 cells to 5-fluorouracil (5-Fu) treatment by suppressing cell proliferation. In conclusion, these data indicate that FOXA1 promoted proliferation, migration, invasion, and decreased chemosensitivity of GC cells to 5-Fu treatment through transcriptional activator KRT7. The present study provides a novel therapeutic strategy for the enhancement of efficacy in GC treatment and provides important insights into the molecular mechanism underlying 5-FU-mediated chemoresistance.

    Abstract Objective: To provide biomarkers related to the radiation response of patients to avoid unnecessary side effects on those who were not sensitive to radiotherapy.
    Patients and methods: In the present study, we compared the different four proteins (PDIA3, Vimentin, Galectin3, Dhe3) patterns in rectal tumor tissue before and after radiation therapy by using 2-D PAGE, mass spectrometry, and bioinformatics analysis.
    Results: The protein level of Galectin3 and PDIA3 were downregulated in rectal cancer patients before and after radiotherapy (1.42 folds); while Dhe3 protein and Vimentin were upregulated (1-2 folds), and we also revealed Vimentin as its role in the negative regulation of the well-known transcription factor ATF4.
    Conclusions: Our study showed that four candidate proteins, including PIDA3, Galectin3, Dhe3, and Vimentin, might be the potential biomarkers in the identification of radiation response in rectal cancer.

    Abstract Wetland species mat rush (Juncus effusus L.) is an important economic plant, but no information is available regarding plant regeneration, callus induction, and its proliferation from in vitro seed grown plantlets. The present study investigates the effects of growth regulator combinations and medium innovation on tissue culture system of five mat rush varieties. Addition of N6-benzyladenine (BA) and 2,4-dichlorophenoxyacetic acid (2,4-D) in Murashige and Skoog (MS) medium showed significantly positive effect on callus proliferation, plant regeneration, and its multiplication compared to the medium devoid of BA. The highest callus induction frequency (80.95%, 90.48%, 75.40%, 70.83%, and 83.33%) was observed in MS medium containing 0.5 mg L⁻¹ (2.2 μM) BA in Yinlin-1, Nonglin-4, Gangshan, Taicao, and Taiwan green, respectively. Various growth regulator combinations with successive subculture (medium replacement) were found essential to develop organogenic calluses and to regenerate shoots. The combination of 0.1 mg L⁻¹ BA (0.4 μM) and 2 mg L⁻¹ 2,4-D (9.0 μM) in MS medium was found best for callus proliferation for all the varieties under trial. The plant regeneration required two steps involving successive medium replacements as well as optimal hormonal balances. Successful plant regeneration (over 70%) was observed only by transferring the organogenic callus from regeneration medium I [MS medium containing 0.5 mg L⁻¹ BA (2. μM) and 1.0 mg L⁻¹ kinetin (KT; 4.6 μM)] to the regeneration medium II [MS medium containing 0.5 mg L⁻¹ BA (2.2 μM), 1.0 mg L⁻¹ KT (4.6 μM) and 3.0 mg L⁻¹ indoleacetic acid (IAA; 17.1 μM)]. Our results confirmed the importance of the ratio of auxin (IAA) to cytokinin (BA and KT) in the manipulation of shoot regeneration in J. effusus L. The maximum plant survival frequency and multiplication rates (90.97% and 5.40 and 94.23% and 8.25) were recorded in the presence of 0.5 mg L⁻¹ BA (2.2 μM) in the 1/2 MS multiplication medium for the varieties of Nonglin-4 and Taicao, respectively. About 100% survival rate was also observed for all the varieties in soil conditions. The efficient plant regeneration system developed here will be helpful for rapid micropropagation and further genetic improvement in J. effusus L.

    Abstract Chelate-assisted phytoextraction by high biomass producing plant species enhances the removal of heavy metals from polluted environments. In this regard, Juncus effusus a wetland plant has great potential. This study evaluated the effects of elevated levels of manganese (Mn) on the vegetative growth, Mn uptake and antioxidant enzymes in J. effusus. We also studied the role of citric acid and EDTA on improving metal accumulation, plant growth and Mn toxicity stress alleviation. Three-week-old plantlets of J. effusus were subjected to various treatments in the hydroponics as: Mn (50, 100 and 500 microM) alone, Mn (500 microM) + citric acid (5 mM), and Mn (500 microM) + EDTA (5 mM). After 2 weeks of treatment, higher Mn concentrations significantly reduced the plant biomass and height. Both citric acid and EDTA restored the plant height as it was reduced at the highest Mn level. Only the citric acid (but not EDTA) was able to recover the plant biomass weight, which was also obvious from the microscopic visualization of mesophyll cells. There was a concentration dependent increase in Mn uptake in J. effusus plants, and relatively more deposition in roots compared to aerial parts. Although both EDTA and citric acid caused significant increase in Mn accumulation; however, the Mn translocation was enhanced markedly by EDTA. Elevated levels of Mn augmented the oxidative stress, which was evident from changes in the activities of antioxidative enzymes in plant shoots. Raised levels of lipid peroxidation and variable changes in the activities of antioxidant enzymes were recorded under Mn stress. Electron microscopic images revealed several modifications in the plants at cellular and sub-cellular level due to the oxidative damage induced by Mn. Changes in cell shape and size, chloroplast swelling, increased number of plastoglobuli and disruption of thylakoid were noticed. However, these plants showed a high degree of tolerance against Mn toxicity stress, and it removed substantial amounts of Mn from the media. The EDTA best enhanced the Mn uptake and translocation, while citric acid best recovered the plant growth.

    Abstract Tetraploidy was induced in vitro in mat rush (Juncus effusus L.) cultivar Nonglin-4 by exposure to colchicine (0, 50, 100 and 500 mg dm⁻³) for 6, 12 and 24 h. Flow cytometric analysis was used to confirm the ploidy level. Anatomical and ultrastructural analyses at cellular and subcellular levels in tetraploid and diploid control plants revealed differences between diploid and tetraploid plants. The leaf epidermis had larger stomata but lower stomatal density in tetraploid plants. In addition, mesophyll cells in tetraploid plants appeared more compact and showed less intercellular spaces along with increased size of vascular bundles. However, a significant reduction of chlorophyll content was observed in tetraploid plants that might be the result of structural modification in the lamellar membranes of chloroplasts.

    Abstract Anew peptide, designated as Buthus martensi Karch (BmK) AngM1, with an isoelectric point (pI) of 5.8 was purified and characterized from the venom of Buthus martensi Karch. The molecular mass was calculated as 7040.5 Da from multiple-charged ions by elelctrospray ionization mass spectroscopy (ESI/MS). The complete amino acid sequence of BmK AngM1 of 64 amino acid residues was determined by automatic sequencing of N-terminal part of the native peptide and the fragments of reduced and S-carboxymethylated (RCM)-peptide degraded by Staphylococcus aureaus V(8) protease and TPCK(N-p-Tosyl-L-phenylalanine chloromethyl ketone)-treated trypsin. Bioactivity tested using mouse-twisting model showed an evident analgesic effect with 63.0% (P < 0.001) inhibition efficiency at the dose of 0.8 mg/kg, but the LD(50) was larger than 50 mg/kg. Electrophysiological studies showed that BmK AngM1 at the concentration of 1 microm obviously inhibit voltage-dependent Na(+) current (I(Na)) and voltage-dependent delayed rectifier K(+) current (I(K)) but had no effects on transient K(+) current.
