Objective To exPlore the effect of mammalian target of raPamycin ( mTOR ) inhibitor eVerolimus on radiosensitiVity of human non_small cell lung cancer cell line in vitro by using eVerolimus to inhibit mTOR signaling Pathway of A549. Methods Human non_small cell lung cancer cell line A549 was subjected to radiation alone or in combination with eVerolimus treatment. The 50%inhibition concentration ( IC50 ) of eVerolimus in A549 cells was detected by methylthiazol tetrazolium ( MTT) assay in vitro. EVerolimus at the 20%inhibition concentration ( IC20 ) was used to Pretreat A549 cells for 24 h. Cells were then irradiated by X_ray with 2,4,6,8 Gy. The cell surViVal fraction was comPuted by clone formation. Cell surViVal curVe was fitted by multitarget one_hit model, and mean lethal dose ( D0 ), dose quasithreshold ( Dq ), surViVal fraction at 2 Gy ( SF2 ), and sensitization enhancement ratio (SER) were calculated. The exPression ofγ_H2AX was determined by Western blotting and then the relatiVe gray Values were analyzed. Results EVerolimus significantly imProVed the sensitiVity of A549 cells to radiation. The D0 , Dq and SF2 of eVerolimus+irradiation grouP were significantly lower than those of irradiation grouP. The SER was 1. 36. The residual amount of γ_H2AX Protein in the eVerolimus + irradiation grouP was significantly higher than that of the irradiation grouP. Conclusion EVerolimus inhibiting mTOR signaling Pathway can increase the radiosensitiVity of A549 cells.

Organic solvent tolerant microorganism(OSTM) is a novel extremophile and it hasn't been systematically studied until 1980s.Relying on certain mechanisms,the OSTM is able to effectively de-fend and decrease the toxicity from organic solvents,which enable the OSTM to be potentially applied in the industrial fields such as whole-cell catalysis and environmental treatment,etc.The comprehen-sively understanding of the mechanisms involved in organic solvent tolerance of OSTM could be com-bined with genetic engineering in order to modify and optimize the various specifications of OSTM,and further broaden its application in other industrial areas.Latest studies on the tolerant mechanisms of OSTM,in this paper,will be reviewed from four aspects such as vesicle exocytosis and changes of phos-pholipid composition in membrane,etc.Besides,the application of OSTM in whole-cell catalysis and other fields will be introduced.

To improve ethanol production in Saccharomyces cerevisiae,an integration plasmid pUPGKAT with PGK promoter(phosphoglycerate kinase promoter),adh1 gene(the coding sequences of alcohol dehydrogenaseⅠ) and CYC1 terminator(Cytochrome c transcription terminator) was constructed.Firstly,a fusion fragment composed of PGK promoter and adh1 gene was generated by over lap extension PCR and ligated into pUG6 resulting in plasmid pUPGKA.Subsequently,CYC1 termi nator was amplified from pSH65 by PCR and ligated to the SpeⅠand SacⅡrestriction site of pUPGKA.To integrate PGK-adh1-CYC1 into S.cerevisiae genome,pUPGKAT was digested by TthⅢⅠand the lin-earized plasmid was used to transform S.cerevisiae YS2-△adh2(adh2 disrupted strain) by lithium acetate method.The yeast mutant YS2-△adh2-adh1 which had the adh1 gene placed under the PGK promoter and harbored the adh2 deletion was constructed.Anaerobic fermentation showed overexpression of adh1 by PGK promoter resulted in a 8.84% higher ethanol production compared to YS2-△adh2.

Chemotherapy-induced neuropathy is a serious clinical problem for patients receiving cancer treatment. The aim of this study was to investigate the potential efficacy of pregabalin in chemotherapy-induced neuropathy in rats. A total of 35 male Sprague-Dawley rats were randomly divided into 5 groups: group 1, naive control; group 2, treated with pregabalin (30 mg/kg p.o., for 8 days); group 3, docetaxel was given by single intravenous infusion at 10 mg/kg; groups 4 and 5, pregabalin at 10 mg/kg and 30 mg/kg respectively was orally administered for 8 days after the docetaxel treatment. On day 8, behavioral test was performed, and substance P and CGRP release in dorsal root ganglion (DRG) and sciatic nerve were analyzed by electron microscope. Our results showed that docetaxel induced mechanical allodynia, mechanical hyperalgesia, heat hypoalgesia, cold allodynia, and sciatic nerve impairment and substance P and CGRP release in DRG. However, oral administration of pregabalin (10 mg/kg and 30 mg/kg) for 8 consecutive days significantly attenuated docetaxel-induced neuropathy by ameliorating heat hypoalgesia, cold allodynia, impairment of sciatic nerve and reducing the release of substance P and CGRP. The findings in the present study reveal that pregabalin may be a potential treatment agent against chemotherapy-induced neuropathy.

The leukocytic phagocytosis rate and the index of phagocytosis of rats on cross-linked agar beads entrapped attapulgite clay (CAA) hemoperfusion were studied. The results revealed that the leukocytic phagocytosis rate and the index of phagocytosis descended significantly after 1 hour and rose gradually after 6 hours. Finally it reached the normal level after 48 hours. Hemoperfusion repeated two times gave similar results. In conclusion, the function of leukocytic phagocytosis declined temporarily during CAA hemoperfusion. Many times hemoperfusion will not notably affect the body's defense system of rats.

To investigate the anticancer effects of ring C in 18β-glycyrrhetinic acid (GA), a series of GA derivatives featured with 9(11)-ene moiety in ring C were designed and synthesized. The structures were confirmed by IR, LC-MS and 1H NMR. Their inhibitory effects towards human prostate cancer PC-3 and leukemia HL-60 cell lines were determined. Most of the derivatives displayed stronger antiproliferative activities than GA. Particularly, compound 14 showed promising anticancer activity with the GI50 values of 4.48 µmol · L(-1) and 1.2 µmol · L(-1) against PC-3 and HL-60 cells respectively, which is worth further study.
