Abstract
BACKGROUND High-intensity chemotherapy regimens are often used in adult T-cell lymphoblastic lymphoma (T-LBL) patients. Nevertheless, the response rate remains unsatisfactory due to emergence of chemoresistance. Growing evidence has shown that long non-coding RNAs (lncRNAs) are involved in tumor progression and chemoresistance. Herein, we investigated the potential role of lncRNAs in T-LBLs. METHODS RNAseq was used to screen and identify candidate lncRNAs associated with T-LBL progression and chemoresistance. Luciferase reporter assay was used to examine the binding of miR-371b-5p to the 3'UTR of Smad2 and LEF1, and the binding of TCF-4/LEF1 to the promoter of LINC00183. Chromatin immunoprecipitation assay was undertaken to analyze the connection between LEF1 and the LINC00183 promoter region. RNA immunoprecipitation assays were used to explore the mechanism whereby LINC00183 regulated miR-371b-5p. MTT and flow cytometry assays were used to measure apoptosis of T-LBL cells. RESULTS LINC00183 was upregulated in T-LBL progression and chemoresistant tissues in both the Sun Yat-sen University Cancer Center dataset and the First Affiliated Hospital of Anhui Medical University dataset. High expression of LINC00183 was correlated with poorer overall survival and progression-free survival of T-LBL patients compared to those with low expression of LINC00183. Furthermore, miR-371b-5p was negatively regulated by LINC00183. In vivo and in vitro assays showed that LINC00183-mediated T-LBL chemoresistance depended on miR-371b-5p expression. The direct binding of miR-371b-5p to Smad2 and LEF1 was verified by luciferase assays. It was shown that TCF4/LEF1 could bind to the LINC00183 promoter site and increase its transcript level. Downregulation of miR-371b-5p led to increased expression of Smad2/LEF1, and in turn increased LINC00183 expression. Additionally, phospho-Smad2 promotes nuclear translocation of β-catenin, LINC00183 downregulation decreased chemoresistance induced by β-catenin and TGF-β1 in T-LBL cells. CONCLUSION We unraveled a β-catenin-LINC00183-miR-371b-5p-Smad2/LEF1 feedback loop that promotes T-LBL progression and chemoresistance, indicating that LINC00183 may serve as a potential therapeutic target in T-LBLs.

Abstract
In low-dimensional Ising spin systems, an interesting observation is the presence of step magnetization at low temperatures. Here we combine both DC and pulsed magnetic fields to study the 1/3 magnetization plateau and multiple steps in the Ising spin-chain material α-CoV2O6. Magnetization in pulsed fields is quite different from that in DC fields, showing multiple steps in an intermediate range of 4.2-6 K, inverted hysteresis below 4.2 K and asymmetric magnetization in negative fields below 11 K. We demonstrate that these unusual behaviors in magnetization are caused by the spin dynamics and the anomalous magnetocaloric effect (MCE) in α-CoV2O6, i.e., abrupt changes of sample temperature in adiabatic conditions. We successfully separate the influence between the intrinsic slow spin dynamics and the quasi-extrinsic temperature change. From the MCE, we find that some irreversible behavior is originated from the slow spin dynamics. Two different slow dynamics associated with the metastable steps are observed: one is sensitive to the slow field sweep rate at the order of ∼mT s-1and weakly depends on temperature, while the other responds to the rapid field sweep rate of ∼kT s-1and dominates at lowest temperature. We also distinguish that the metastable transition atH4is the first order and crucial for the ferrimagnetic to ferromagnetic transition. This study is useful to the understanding of multistep magnetization in α-CoV2O6and sheds light on recent experimental findings of related compounds.

Abstract
Objective: To observe the efficacy and safety of recombinant tissue-type plasminogen activator (rtPA) intravenous thrombolysis (IVT) in the treatment of acute cerebral infarction with hyperdense middle cerebral artery sign (HMCAS). Methods: Acute cerebral infarction patients with HMCAS from July 2010 to November 2015 at the First Affiliated Hospital of Dalian Medical University were collected.These patients were divided into two groups depending on whether they received IVT or not.The Nation Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS) were used to evaluate early and long-time therapeutic effects.Efficacy and safety were compared between the two groups. Results: A total of 93 patients were eligible for the analysis, with 45 cases in IVT group and 48 cases in non-IVT group.As time went by, NIHSS score in IVT group showed significant downward trend than the non-IVT group.The rate of patients with good outcome in IVT group was higher than that in non-IVT group (P<0.05). The rate of hemorrhage transformation (HT) in IVT group and non-IVT group was 35.6% (16/45) and 10.4% (11/48), respectively, and the difference was statistically significant (P<0.05). While no statistically significant difference was found about the rate of symptomatic intracranial hemorrhage (sICH) (8.9% vs 2.1%, P>0.05) and mortality (33.3% vs 27.1%, P>0.05) between these two groups.Logistic regression analysis identified relativity between IVT treatment and good outcome (P<0.05), hemorrhage transformation (P<0.05), rather than mortality (P>0.05). Conclusions: Intravenous thrombolysis with rt-PA is an effective and safe treatment for most acute ischemic stroke patients with HMCAS and can promote early neurologic improvement and significantly improve long-term functional prognosis.Although Ⅳ thrombolysis can increase the risk of overall HT, it does not add risk in sICH and mortality.

Abstract
A novel polysaccharide (LCP50S-2) with antioxidant activity was isolated from Litchi chinensis Sonn. The structure of LCP50S-2 was elucidated on the basis of physicochemical and instrumental analyses, and its average molecular weight was determined by gel permeation chromatography to be 2.19 × 10(2) kDa. The backbone of LCP50S-2 was composed of (1→3)-linked β-L-rhamnopyranosyl residues, (1→4)-linked α-D-xylopyranosyl residues, (1→4)-linked β-D-glucopyranosyl residues, and (1→4)-linked α-D-glucopyranosyl residues which branched at O-6. The two branches consisted of α-L-arabinopyranosyl residues and (1→6)-linked β-D-galactopyranosyl residues terminated with α-L-arabinopyranosyl residues, respectively. In the in vitro antioxidant assay, LCP50S-2 was found to possess DPPH radical-scavenging activity and hydroxyl radical-scavenging activity with IC(50) values of 220 and 266 μg/mL, respectively.

Abstract
OBJECTIVE The exogenous substrate, thymol, was firstly biotransformed by using suspension hairy roots of transgenic Polygonum multflorum, and its biotransformed situation was also investigated. METHODS After five days co-cultivated period, the transformed product was isolated by Thin Layer Chromatograph and Column Chromatograph, with the structure elucidated by physic-chemical methods and spectra data. Meanwhile, the time course of biotransformation (T-C) for thymol was also measured by HPLC to illuminate its bio-transformed situation. RESULTS The glycosylated product, namely DMP, was isolated and purified, which structure was determined as 5-methyl-2-(1-methylethyl) phenyl- beta-D-glucopyranoside. And the distribution of DMP in the medium or culture was varied in different co-cultivated periods, and for five days co-cultivated period, it mainly existed in the medium. CONCLUSION The hairy roots of Polygonum multiflorum were able to convert the aromatic exogenous substrate, thymol, into its glycoside. Furthermore, the time course indicated the relationship between DMP and co-cultivated period.

Abstract
OBJECTIVE To provide theoretical basis for the production of ginsenosides by using modern biotechnologies, the comparative studies of the amount of ginsenosides between the crown galls and Chinese medicinal materials of Panax quinquefolium were carried out. METHODS Total ginsenosides were determined by spectrophotometry, and the contents of ginsenoside Rb1, Rb3, Rc, Re were determined by HPLC. RESULTS (1) The total ginsenosides in the crown galls of Panax quinquefolium (aftert 27 days' cultivation) was almost as much as that of Chinese medicinal material of Panax quinquefolium. (2) The contents of ginsenoside Rb1, Re in the crown galls were about half of that in Chinese medicinal materials of Panax quinquefolium, and ginsenoside Rc was about 80%. But the amount of ginsenoside Rb3 in the crown galls of Panax quinquefolium was much more than that in Chinese medicinal materials of Panax quinquefolium as almost 15 times higher. CONCLUSION The crown galls of Panax quinquefolium may be a new potential resource for large-scale production of ginsenosides.

Abstract
The effects of exogenous phytohormones on hairy root growth and biosynthesis of anthraquinones in the hairy root cultures of Polygonum multiflorum Thunb. were studied. The results showed that the 2,4-D, NAA and 6-BA all have obvious effects on the growth of hairy root cultures and the biosynthesis of anthraquinones. The growth of hairy root and biosynthesis of anthraquinones were strongly restrained by 2,4-D. However, NAA and 6-BA of appropriate concentration were favourable to hairy root growth and anthraquinones production.

Abstract
It was clearly demonstrated that T-DNA of Agrobacterium tumefeciens Ti plasmid was integrated into the cells of crown gall in our experiment. This paper reported the influences of some kinds of physical-chemistry factors on the growth of crown gall of Panax quinquefolium and the production of its main active compounds--ginsenoside Re and ginsensoside Rg1. The results showed that White medium was the best one for ginsensoside Rg1 accumulation (0.095%) among the six media, but ginsensoside Re accumulation (0.194%) was the highest on the MS medium; The highest contents of ginsensoside Re (0.147%) and ginsensoside Rg1 (0.061%) were on the culture 36d and 32d after innoculum respectively; The optimum pH was 5.6 for ginsensoside Rg1 synthesis(0.054%), and 5.8 for ginsensoside Re synthesis(0. 184% ); The contents of ginsensoside Re and ginsensoside Rg1 was the highest in the inoculum of 4 g and 2 g/flask (FW) respectively. The result also indicated that the concentration of inositol in 0.05 g/L could obviously promote ginsensoside Re synthesis (0.182%), and in 0.30 g/L for ginsensoside Rg1 (0.055%).

Abstract
Reaction of [Mo3Y(mu-S)3(dtp)4(H2O)] (Y = O, S; dtp = S2P(OC2H5)2(-)) with HgI2 gave the novel compound [[Mo3S7(dtp)3]4 x I][(HgI3)3] x 4H2O (1), which contains a [[Mo3S7(dtp)3]4 x I] tetramer and (HgI3)-. Compound 1 has been characterized by IR, Raman, UV/Vis, and NMR spectroscopy and single-crystal X-ray diffraction analysis. It is shown that this formation process can be referred to as a new cluster reaction. The structure and spectroscopic data of the tetramer is also compared with that of the related discrete cluster [Mo3S7(dtp)3 x I]. Crystal data: space group F23, a = 26.786(3) A, V = 19218.7(4) A3, Z = 4, R = 0.059.

Abstract
Three heterometallic cubane-like clusters, [Mo3(mu 3-O)(mu 3-S)3(SnCl3)(dtp)3(py)3] (dtp = S2P(OC2H5)2-, py = C5H5N) (1), (PPN)[Mo3(mu 3-O)(mu 3-S)3(SnCl3)(dtp)3(mu-OAc)(py)] (OAc = CH3COO-, PPN = (C6H5)3PNP(C6H5)3+) (2), and (Et4N)[Mo3(mu 3-O)(mu 3-S)3(SnCl3)(dtp)2(mu-OAc)2(py)] (3) have been prepared by the reaction of [Mo3(mu 3-O)-(mu-S)3(dtp)4(H2O)] (4), [Mo3(mu 3-O)(mu-S)3(dtp)3(OAc) (py)] (5), and [Mo3(mu 3-O)(mu-S)3(dtp)2(OAc)2 (py)] (6) with SnCl2, respectively. They have been characterized by IR, UV-vis, 31P NMR, 95Mo NMR, and X-ray structure analysis. All of these heterometallic clusters have a [Mo3OS3Sn]6+ core but contain a different arrangement of peripheral ligands. As far as the neutral cluster 1 is concerned, there is no bridging OAc ligand, while only one bridging OAc ligand is observed for cluster 2 and two are for cluster 3. The Mo-Mo distances are about 0.03-0.04 A shorter than those of the starting trimolybdenum clusters. This indicates that the incorporation of SnCl3- fragment into (Mo3) clusters makes the Mo-Mo bonding enhanced. Crystal data for 1: triclinic, space group P-1, a = 10.7423(2) A, b = 14.0357(1) A, c = 16.9346(2) A, alpha = 84.054(1) degrees, beta = 87.095(1) degrees, gamma = 84.517(1) degrees, V = 2525.82(6) A3, Z = 2, R = 0.038 for 5584 reflections (I > 2.0 sigma(I)). Crystal data for 2: triclinic, space group P-1, a = 12.9529(1) A, b = 15.6324(2) A, c = 19.6355(1) A, alpha = 92.083(1) degrees, beta = 97.908(1) degrees, gamma = 110.337(1) degrees, V = 3677.41(6) A3, Z = 2, R = 0.034 for 8665 reflections (I > 2.0 sigma(I)). Crystal data for 3: monoclinic, space group P2(1)/n, a = 14.0852(5) A, b = 15.1324(5) A, c = 23.2691(7) A, beta = 97.371(1) degrees, V = 4918.7(3) A3, Z = 4, R = 0.049 for 4970 reflections (I > 2.0 sigma(I)).

Abstract
The unusual oxygen-linked double cubane-like cluster compound {[Mo(3)PbOS(3)](OAc)(2)(py)(3)(dtp)(2)O}(2) (A) (dtp = S(2)P(OEt(2))(-), OAc = CH(3)COO(-), py = C(5)H(5)N) was obtained for the first time by the reaction of the mixed S/O-bridged cluster [Mo(3)(&mgr;(3)-O)(&mgr;-S)(3)(dtp)(4)H(2)O] (B) with Pb(OAc)(2).3H(2)O in the presence of excess CH(3)COOH and pyridine. It has been characterized by IR, Raman, UV-vis, and X-ray structure analysis. The molecule contains a crystallographic center of inversion and can be viewed as consisting of two [Mo(3)PbOS(3)](6+) cubane-like cores linked through a pair of oxygen bridges with Mo-(&mgr;-O) bond lengths of ca. 1.89 Å. The cell dimensions are a = 11.705(8) Å, b = 19.527(8) Å, c = 20.670(9) Å, beta = 98.14(4) degrees, V = 4677(8) Å(3), Z = 2 in the space group P2(1)/n. The final R = 0.056, R(w) = 0.068 for 5424 reflections with I >/= 3sigma(I). The average Mo-Mo bond distance is 2.613(1) Å and the nonbonding Mo-Pb distances lie in the range from 3.997(1) to 4.090(1) Å. The spectra of IR, Raman, and UV-vis spectra are also shown in this paper.
