Abstract
Objective: To construct a three-dimensional (3D) finite element model and analyze the biomechanical characteristics during mandibular second molar mesialization using customized lingual appliances and mini-implant. Methods: One adult student volunteer from The First Affiliated Hospital of Zhengzhou University with lower left first molar extraction was selected. After CT scanning, Mimics, Geomagic, ANSYS were employed to develop a 3D finite element model including customized lingual brackets, stainless steel lingual arch wire, buccal buckles, lower dentition, periodontal ligaments and alveolar bone. Four different loading methods (1. the force of 1.470 N loaded at the lingual side only; 2, 3, 4. the forces of 0.490, 0.735 and 0.980 N loaded at both buccal and lingual sides, respectively.) were included. The initial displacements of the lower second molar and stress distribution in the periodontal ligaments were analyzed. Results: More uniform stress distributions in the periodontal membrane of mandibular left second molar were found when the mesial force were loaded at both buccal and lingual sides than the force loaded at lingual side only. More inclination of the second molar was observed when force loaded at both sides than at lingual side only. With the values of the force increased, the mesial inclination potential of the second molar, the initial movement of the second molar and the stress distribution in the periodontal membrane increased. Under the force of 0.735 N at both buccal and lingual sides, mesially inclined initial displacements of the mandibuar second molar were observed and the stress values of von Mises was in the suitable area. Conclusions: Less second molar rotation was found when the force loaded at both buccal and lingual sides than loaded at lingual side only. However, force loaded at both sides would increase the measial inclination potential of the second molar.

Abstract
Objective: To study the impact to operation safety of preoperative renal artery embolization for management of ≥10 cm renal cell carcinoma. Methods: The clinical data of 239 cases with ≥10 cm renal cell carcinoma which all had underwent operation in Department of Urology, Peking University First Hospital from January 2002 to December 2014 were retrospectively analyzed. Fifty-three patients underwent preoperative renal artery embolization (therapeutic group) and 186 patients did not (control group). The effect of embolization on operative time, transfusion requirements, hospitalization, ICU stay and perioperative complications were analyzed by comparing the two groups using rank sum test and χ(2) test or Fisher exact test. Results: Comparing the therapeutic group and control group, there was significant difference in tumor location (on the left or right). The mean age, sex, mean primary tumor size, and TNM stage were similar in both groups. Comparing the therapeutic group and control group, there were more open surgeries in therapeutic group (96.2% vs. 82.3%, χ(2)=6.438, P=0.013). There were no significant differences in mean operative time (238 (525) minutes vs. 208 (583) minutes, Z=-2.182, P=0.062). The mean blood transfusion (700 (1 900) ml vs. 925 (8 800) ml, Z=-1.064, P=0.006) had significant difference. The therapeutic group had a longer mean hospitalization (21 (50) days vs. 15 (79) days, Z=-4.322, P=0.000) and higher rate of intensive care unit stay (54.7% vs. 34.4%, χ(2)=6.103, P=0.027). There was no significant difference in perioperative complications between two groups (0 vs.3.2%, P=0.408). Conclusion: Preoperative renal artery embolization in ≥10 cm renal cell carcinoma patients undergoing operation provides benefit in increasing operation safety and reducing perioperative death.

Abstract
The aims are to evaluate the efficacy and safety of aripiprazole for tic disorders (TDs) in children and adolescents. We searched PubMed, Embase, PsychINFO, Cochrane database as well as Chinese databases of CNKI, VIP, CBM and Wanfang from the database inception to October 2016, and 17 full-text studies (N=1305) were included in our article. The meta-analysis of 10 studies (N=817) showed that there was no significant difference in the reduction of total YGTSS score between aripiprazole and other drugs, and meta-analysis of 7 studies (n=324) which used tic symptom control ≧30% as outcome measure showed that there was no significant difference between aripiprazole and other treatments. The most common AEs of aripiprazole were the drowsiness, nausea/vomiting and increased appetite, and meta analysis which used the TESS scale as the outcome measurement showed that there was a significant difference between aripiprazole and haloperidol. In conclusion, these data provide moderate quality evidence that aripiprazole could be an effective and safe treatment option for TDs, and results from further trials are urgently needed to extend this evidence base.

Abstract
AIMS Xanthohumol isolated from hops has been reported to exhibit anticancer effects in diverse human cancers. However, its effect on breast cancer has not yet been clearly defined. The purpose of this study was to investigate the effects of xanthohumol on breast cancer cell proliferation. MATERIALS AND METHODS After treatment with 5 μM, 10 μM, and 20 μM xanthohumol for 48 h, cells from the human breast cancer cell line MDA-MB-231 were studied using colony assay, flow cytometry, and western blotting. RESULTS The survival rate of the MDA-MB231 cells treated with 10 μM and 20 μM xanthohumol for 48 h decreased significantly by 64.7 ± 1.8% and 40.1 ± 1.8%, respectively. The numbers of SubG0/G1 cells in the group treated with 10 μM and 20 μM xanthohumol increased significantly to 11.3 ± 0.2 and 18.4 ± 0.1, respectively. A ladder pattern of DNA fragmentation was also observed. Xanthohumol increased the expression of Bax in the mitochondria, which correspondingly decreased in the cytoplasm. The activity of caspase-3 and caspase-9 was shown to increase significantly in the treated groups but not in the control group. CONCLUSIONS Xanthohumol inhibited the proliferation of MDA-MB-231 cells through a mitochondria- and caspase-dependent apoptotic pathway. This result suggests that xanthohumol might serve as a novel therapeutic drug for breast cancer.

Abstract
The RENO experiment has analyzed about 500 live days of data to observe an energy dependent disappearance of reactor ν[over ¯]_{e} by comparing their prompt signal spectra measured in two identical near and far detectors. In the period between August of 2011 and January of 2013, the far (near) detector observed 31 541 (290 775) electron antineutrino candidate events with a background fraction of 4.9% (2.8%). The measured prompt spectra show an excess of reactor ν[over ¯]_{e} around 5 MeV relative to the prediction from a most commonly used model. A clear energy and baseline dependent disappearance of reactor ν[over ¯]_{e} is observed in the deficit of the observed number of ν[over ¯]_{e}. Based on the measured far-to-near ratio of prompt spectra, we obtain sin^{2}2θ_{13}=0.082±0.009(stat)±0.006(syst) and |Δm_{ee}^{2}|=[2.62_{-0.23}^{+0.21}(stat)_{-0.13}^{+0.12}(syst)]×10^{-3} eV^{2}.

Abstract
An association has been suggested between Marfan syndrome (MFS) and the nodular bronchiectatic form of lung disease caused by non-tuberculous mycobacteria (NTM). We evaluated the prevalence of bronchiectasis in 79 adult patients with MFS using computed tomography (CT) imaging. Airway dilation indicative of bronchiectasis (22/79, 28%) and bronchioloectasis (10/79, 13%) were relatively common, although the extent of dilation was not severe and was frequently confined to a single lobe. However, bronchiolitis was evident in only three patients (4%), and no patient was diagnosed with NTM lung disease.

Abstract
Alternaria rot, caused by Alternaria alternata, was observed in commercial peach orchards in South Carolina. Single-spore isolates formed two phenotypically different culture morphologies on two artificial media. Isolates highly resistant (HR) to boscalid were also HR to penthiopyrad. Among isolates HR and medium resistant (MR) to boscalid and penthiopyrad, we detected isolates that were MR to fluopyram and HR to fluxapyroxad. Sequence analysis of succinate dehydrogenase (sdh) genes sdhB, sdhC, and sdhD revealed that resistant phenotypes were associated with point mutations leading to amino acid substitutions. In particular, H277Y/R in the SDHB and H134R in SDHC were consistently associated with the boscalid HR phenotype. The highest effective concentration that inhibits growth by 50% (EC50) values to penthiopyrad were conferred by H134R and D123E, whereas H134R conferred low resistance and MR to fluxapyroxad. A previously undescribed mutation, G79R, was identified in our collection conferring HR to both boscalid and penthiopyrad. The point mutations associated with highest EC50 values to all four FRAC 7 fungicides were H277L and H134R. The outbreak of Alternaria rot demonstrates that fungicide programs containing "medium to high-risk fungicides" may promote disease outbreaks by secondary pathogens that typically are outcompeted or controlled effectively, while still controlling the primary target disease.

Abstract
Five 3,4-seco-cycloartane triterpenoids were isolated from the stems of Kadsura ananosma, two of which had rearranged 5/6 consecutive carbocycle rings C/D (trivially named ananosins A (1) and B (2)), one had a migrated CH3-18 (named ananosins C (3)), and two were analogs, ananosins D (4) and E (5). Their structures were characterized by comprehensive spectroscopic analysis, especially using 2D NMR spectra. A biogenetic pathway to 1 was proposed. These 5 compounds, together with 5 known analogs isolated from the same origin, were evaluated for their cytotoxicity against HL-60, SMMC-7721, A-549, PANC-1, and SK-BR-3 human cancer cells, but were inactive.

Abstract
Eukaryote transcription is controlled by regulatory DNA sequences and transcription factors, so transcriptional control of gene plays a pivotal role in gene expression. In this study, we identified the region of the CYP6B6 gene promoter of Helicoverpa armigera which responds to the plant secondary toxicant 2-tridecanone. Transient transfection assay results from five of stepwise deletion fragments linked to the luciferase reporter gene revealed that the promoter activity of each CYP6B6 fragment was significantly higher than that of their basal activity after the Sf9 cells were treated with 2-tridecanone. Among all, the fragment spanning -373 to +405 bp of the CYP6B6 promoter showed an obviously 2-tridecanone inducibility (P<0.0001), which might have the 2-tridecanone responsive element based on promoter activity. Electrophoretic mobility shift assays revealed that the nuclear protein extracted from midgut of the 6th instar larva of H. armigera, reared on 10 mg 2-tridecanone per gram artificial diet for 48 h, could specifically bind to the active region from -373 to 21 bp of the CYP6B6 promoter. The combination feature also appeared when using a shorter fragment from -292 to -154 bp of the CYP6B6 promoter. Taken together, we found a 2-tridecanone core responsive region between -292 and -154 bp of the CYP6B6 promoter. This may lead us to a better understanding of transcriptional mechanism of P450 gene and provide very useful information for the pest control.

Abstract
Thirteen new heterodimeric ent-kauranoids, bistenuifolins A-M (1-13), were isolated from the aerial parts of Isodon tenuifolius. The constituent units of compounds 1-6 were linked by a six-membered dihydropyran ring, while those of compounds 7-11 were joined by a rare single carbon-carbon bond (C-16→C-17'). The constituent units of 12 and 13 were linked via an unusual cyclobutane moiety. The structures of these metabolites were established via spectrometric analyses, and the absolute configurations of 1 and 4 were defined by single-crystal X-ray diffraction. Selected compounds were evaluated for their cytotoxicity against a small panel of human tumor cell lines; bistenuifolin B (2) exhibited weak inhibitory effects.

Abstract
Tumor angiogenesis, growth and metastasis are three closely related processes. We therefore investigated the effects of barbigerone on all three in the B16F10 tumor model established in both zebrafish and mouse models, and explored underlying molecular mechanisms. In vitro, barbigerone inhibited B16F10 cell proliferation, survival, migration and invasion and suppressed human umbilical vascular endothelial cell migration, invasion and tube formation in concentration-dependent manners. In the transgenic zebrafish model, treatment with 10μM barbigerone remarkably inhibited angiogenesis and tumor-associated angiogenesis by reducing blood vessel development more than 90%. In vivo, barbigerone significantly suppressed angiogenesis as measured by H and E staining of matrigel plugs and CD31 staining of B16F10 melanoma tumors in C57BL/6 mice. Furthermore, it exhibited highly potent activity at inhibiting tumor growth and metastasis to the lung of B16F10 melanoma cells injected into C57BL/6 mice. Western blotting revealed that barbigerone inhibited phosphorylation of AKT, FAK and MAPK family members, including ERK, JNK, and p38 MAPKs, in B16F10 cells mainly through the MEK3/6/p38 MAPK signaling pathway. These findings suggested for the first time that barbigerone could inhibit tumor-angiogenesis, tumor growth and lung metastasis via downregulation of the MEK3/6/p38 MAPK signaling pathway. The findings support further investigation of barbigerone as a potential anti-cancer drug.

Abstract
To study the chemical constituents of the branches of Tamarix rasissima, repeated silica gel column chromatography, Sephadex LH-20 chromatography and recrystallization were applied for chemical constituents isolation and purification. Ten phenolic compounds were isolated from the n-BuOH fraction and their structures were elucidated by physical properties and spectra analysis such as UV, ESI-MS and NMR as monodecarboxyellagic acid (1), ellagic acid (2), 3, 3'-di-O-methylellagic acid (3), 3, 3'-di-O-methylellagic acid-4-O-beta-D-glucopyranoside (4), 3, 3'-di-O-methylellagic acid-4'-O-alpha-D-arabinfuranoside (5), ferulic acid (6), isoferulic acid (7), caffeic acid (8), 4-O-acetyl-caffeic acid (9), and 4-methyl-1, 2-benzenediol (10). All compounds except for isoferulic acid were isolated firstly from this plant except for isoferulic acid, and compounds 5, 9 and 10 were obtained from Tamarix genus for the first time.

Abstract
Environmental geochemical baseline models of Cu, Zn, Pb, As, Hg were established by standardized method in the ehernozem, chestnut soil, sierozem and saline soil from the Ili river valley region. The theoretical baseline values were calculated. Baseline factor pollution index evaluation method, environmental background value evaluation method and heavy metal cleanliness evaluation method were used to compare soil pollution degrees. The baseline factor pollution index evaluation showed that As pollution was the most prominent among the four typical types of soils within the river basin, with 7.14%, 9.76%, 7.50% of sampling points in chernozem, chestnut soil and sierozem reached the heavy pollution, respectively. 7.32% of sampling points of chestnut soil reached the permitted heavy metal Pb pollution index in the chestnut soil. The variation extent of As and Pb was the largest, indicating large human disturbance. Environmental background value evaluation showed that As was the main pollution element, followed by Cu, Zn and Pb. Heavy metal cleanliness evaluation showed that Cu, Zn and Pb were better than cleanliness level 2 and Hg was the of cleanliness level 1 in all four types of soils. As showed moderate pollution in sierozem, and it was of cleanliness level 2 or better in chernozem, chestnut soil and saline-alkali soil. Comparing the three evaluation systems, the baseline factor pollution index evaluation more comprehensively reflected the geochemical migration characteristics of elements and the soil formation processes, and the pollution assessment could be specific to the sampling points. The environmental background value evaluation neglected the natural migration of heavy metals and the deposition process in the soil since it was established on the regional background values. The main purpose of the heavy metal cleanliness evaluation was to evaluate the safety degree of soil environment.

Abstract
1. The aim of this study was to investigate the localisation of the transient receptor potential vanilloid channel type 6 (TRPV6) in egg shell gland (ESG) and examine the dynamic expression of TRPV6 and Calbindin-d28k (CaBP-D28k), as well as the changes in concentration of total calcium (Ca), total inorganic phosphorus (P), alkaline phosphatase (ALP), parathyroid hormone (PTH) and calcitonin (CT) in plasma during the oviposition cycle. 2. The plasma ALP activity was notably increased at 8 h. In addition, plasma CT was highest at 0 h and significantly lower at 8 h. The change of plasma PTH concentration increased slightly post-oviposition and reached a maximum at 16 h. 3. Immunohistochemical analysis indicated that TRPV6 was strongly localised to the apical luminal epithelium of the mucosa. The mRNA levels of TRPV6 and CaBP-D28k in the ESG remained very low from 0 to 4.5 h, but were significantly increased at 16 h. Furthermore, Western blotting analysis showed that the expression of TRPV6 and CaBP-D28k also reached a maximum at 16 h and was different from the concentration of CaBP-D28k. 4. In conclusion, the epithelial Ca(2+) channel TRPV6 is strongly expressed in the epithelial cells of the eggshell gland, and the increase of TRPV6 and CaBP-D28k mRNA and protein expression during eggshell formation suggests that active Ca(2+) transcellular transport exerts significant effects in delivering active calcium in the ESG.
