Abstract
Objective: To clarify the definition of severe pulmonary tuberculosis and its inclusion criteria by summarizing and analyzing the studies of severe pulmonary tuberculosis (TB). Methods: A systematic search of Medline (via PubMed), Cochrane Library, Web of Science, Web of Science, Epistemonikos, Embase, CNKI, WanFang database, and CBM database was conducted to collect studies published between 2017 and 2022 on patients with severe pulmonary TB. Searches were performed using a combination of subject terms and free words. The search terms included: tuberculosis, severe, serious, intensive care, critical care, respiratory failure, mechanical ventilation, hospitalization, respiratory distress syndrome, multiple organ failure, pulmonary heart disease, and pneumothorax. The definitions and inclusion criteria for severe pulmonary TB in the included studies were extracted. Results: A total of 19 981 studies were identified and 100 studies were finally included, involving 8 309 patients with severe pulmonary TB. A total of 8 (8.00%) studies explicitly mentioned the definition of severe pulmonary TB, and 53 (53.00%) studies clearly defined the inclusion criteria for patients with severe pulmonary TB. A total of 5 definitions and 30 inclusion criteria were extracted. A total of 132 dichotomous variables and 113 continuous variables were included in the outcome indicators related to patients with severe pulmonary TB of concern in the studies. Conclusions: The definition and diagnostic criteria for severe TB are unclear, and there is an urgent need to develop a clear definition and diagnostic criteria to guide clinical practice.

Abstract
Light signaling precisely controls photomorphogenic development in plants. PHYTOCHROME INTERACTING FACTOR 4 and 5 (PIF4 and PIF5) play critical roles in the regulation of this developmental process. In this study, we report CONSTITUTIVELY PHOTOMORPHOGENIC 1 SUPPRESSOR 6 (CSU6) functions as a key regulator of light signaling. Loss of CSU6 function largely rescues the cop1-6 constitutively photomorphogenic phenotype. CSU6 promotes hypocotyl growth in the dark, but inhibits hypocotyl elongation in the light. CSU6 not only associates with the promoter regions of PIF4 and PIF5 to inhibit their expression in the morning, but also directly interacts with both PIF4 and PIF5 to repress their transcriptional activation activity. CSU6 negatively controls a group of PIF4- and PIF5-regulated gene expressions. Mutations in PIF4 and/or PIF5 are epistatic to the loss of CSU6, suggesting that CSU6 acts upstream of PIF4 and PIF5. Taken together, CSU6 promotes light-inhibited hypocotyl elongation by negatively regulating PIF4 and PIF5 transcription and biochemical activity.

Abstract
The apical hook is indispensable for protecting the delicate shoot apical meristem while dicot seedlings emerge from soil after germination in darkness. The development of the apical hook is co-ordinately regulated by multiple phytohormones and environmental factors. Yet, a holistic understanding of the spatial-temporal interactions between different phytohormones and environmental factors remains to be achieved. Using a chemical genetic approach, we identified kinetin riboside, as a proxy of kinetin, which promotes apical hook development of Arabidopsis thaliana in a partially ethylene-signaling-independent pathway. Further genetic and biochemical analysis revealed that cytokinin is able to regulate apical hook development via post-transcriptional regulation of the PHYTOCHROME INTERACTING FACTORs (PIFs), together with its canonical roles in inducing ethylene biosynthesis. Dynamic observations of apical hook development processes showed that ETHYLENE INSENSITVE3 (EIN3) and EIN3-LIKE1 (EIL1) are necessary for the exaggeration of hook curvature in response to cytokinin, while PIFs are crucial for the cytokinin-induced maintenance of hook curvature in darkness. Furthermore, these two families of transcription factors display divergent roles in light-triggered hook opening. Our findings reveal that cytokinin integrates ethylene signaling and light signaling via EIN3/EIL1 and PIFs, respectively, to dynamically regulate apical hook development during early seedling development.

Abstract
1. A better understanding of intestinal development is essential for the intestinal health of poultry. Intestinal villification starts on embryo day E15 and is generally completed before hatching (E21). The development of lymphoid organs in the intestine starts during embryogenesis. However, transcriptional information on the processing of intestinal morphogenesis and immune development during chick embryogenesis is limited.2. In this work, RNA-sequencing was performed using 12 biological replicates to investigate Hy-Line brown chick embryonic small intestinal transcription at E15 and E21. Differentially expressed genes (DEGs) between E15 and E21 were identified. GO and KEGG enrichment analyses, based on the DEGs, were performed to identify key GO terms in the biological process category and key KEGG pathways. PPI networks were constructed based on the DEGs in the key pathways to screen hub genes. The embryonic small intestinal morphology and IgA distribution were observed by histological processing. The serum levels of IgA and lysozyme were measured by ELISA.3. A total of 76.38 Gb of high-quality RNA-sequencing data were generated and uploaded. A total of 2,676 DEGs, between E15 and E21, were identified. Structural development and villification of the small intestine at E15 tended to proceed via the expression of nervous system development-related genes. A combination of the histological and serological results with the transcriptome data indicated that the identified genes and pathways may be strong candidates for intestinal morphogenesis-regulation.4. The small intestine appears to have developed a relatively complete morphology and transport, metabolism, digestion and immunity functions by E21. This work provided a transcriptome profile of the chick embryonic small intestine and provided insights into the intestinal development and health of poultry.

Abstract
Abstract
Aims
Short QT syndrome (SQTS), a disorder associated with characteristic electrocardiogram QT-segment abbreviation, predisposes afflicted patients to sudden cardiac death. Despite some progress in assessing the organ level pathophysiology and genetic changes of the disorder, the understanding of the human cellular phenotype and discovering of an optimal therapy has lagged due to a lack of appropriate human cellular models of the disorder. The aim of this study was to establish a cellular model of SQTS type 5 using human-induced pluripotent stem cell–derived cardiomyocytes (hiPSC-CMs) and gene-edited cell line using CRISPR/CAS9.
Methods and results
This study recruited one patient with short QT syndrome type 5 carrying a mutation in CACNb2 gene as well as one healthy control subject. We generated hiPSCs from their skin fibroblasts, and differentiated hiPSCs into cardiomyocytes (hiPSC-CMs) for physiological. Isogenic control hiPSC-CMs generated by the CRISPR/CAS9 technique were also used for the study.
The hiPSC-CMs from the patient showed a reduced calcium current (ICa-L) density and shortened action potential duration (APD) compared with healthy control hiPSC-CMs and isogenic hiPSC-CMs. Furthermore, they demonstrated abnormal rhythmic activities. Carbachol increased the arrhythmic events in SQTS significantly but not in healthy and isogenic control cells. Gene and protein expression profiling showed a decreased CACNb2 expression in SQTS cells. Quinidine prolonged the APD and abolished arrhythmic activity.
Conclusions
Patient-specific hiPSC-CMs are able to recapitulate single-cell phenotype features of SQTS type 5 and provide novel opportunities to further elucidate the cellular disease mechanism and test drug effects.

Abstract
Objective: To explore the correlation between dietary N-glycolylneuraminic acid (Neu5Gc) intake and chronic inflammation state of body. Methods: A total of 306 samples of 102 types of food were purchased from a supermarket in Xiamen in September 2019, including grains, meat, poultry, seafood, eggs, beans, dairy products, vegetables and fruits. The content of Neu5Gc in food was determined by liquid chromatography-mass spectrometry. A total of 500 healthy freshmen from Xiamen University were selected by using a simple random sampling method. The food frequency questionnaire was used to investigate the food intake in the past year. The food intake was corrected by 3 consecutive 24-hour recalls, and the amount of Neu5Gc intake was calculated. The concentration of anti-Neu5Gc antibody, C-reactive protein (CRP) and interleukin-6 (IL-6) in serum was detected. Spearman correlation analysis was used to explore the correlation between Neu5Gc intake and anti-Neu5Gc antibody, CRP and IL-6 levels. Results: Neu5Gc was mainly found in red meat and liquid dairy products. The contents of Neu5Gc in beef, lamb and pork were (30.32±2.84), (20.39±4.73) and (5.58±1.04) mg/kg, respectively, and in liquid milk and yogurt were (10.87±1.54) and (6.91±0.24) mg/L, respectively. The M (P25, P75) intake of Neu5Gc for all participants was 4.62 (2.20, 8.60) mg/d. The M(P25, P75) intake of Neu5Gc for males about 6.60(2.83, 10.20) was higher than that for females about [3.84 (1.84, 6.35) mg/d] (P<0.001). The M (P25, P75) of serum anti-Neu5Gc, CRP and IL-6 levels were 3.07 (2.17, 4.14) μg/ml, 0.37 (0.22, 0.87) mg/ml and 61.82 (12.23, 315.30) pg/ml, respectively. Spearman correlation analysis showed that the intake level of Neu5Gc was positively correlated with serum anti-Neu5Gc antibody, CRP and IL-6 levels, with rs values about 0.222, 0.102 and 0.126, respectively (all P values <0.05). Conclusion: Dietary Neu5Gc intake is mainly from red meat and liquid dairy products, and its intake level is positively correlated with chronic inflammatory state of body.

Abstract
Light-mediated seedling development is coordinately controlled by a variety of key regulators. Here, we identified two B-box (BBX)-containing proteins, BBX30 and BBX31, as repressors of photomorphogenesis. ELONGATED HYPOCOTYL5, a central regulator of light signaling, directly binds to the G-box cis-element present in the promoters of BBX30 and BBX31 and negatively controls their transcription levels in the light. Seedlings with mutations in BBX30 or BBX31 are hypersensitive to light, whereas the overexpression of BBX30 or BBX31 leads to hypo-photomorphogenic growth in the light. Furthermore, transgenic and phenotypic analysis revealed that the B-box domain of BBX30 or BBX31 is essential for their respective functioning in the regulation of photomorphogenic development in plants. In conclusion, BBX30 and BBX31 act as key negative regulators of light signaling, and their transcription is repressed by ELONGATED HYPOCOTYL5 through directly associating with their promoters.

Abstract
The extracellular matrix protein Hemicentin (HIM-4) is an extracellular factor that regulates anillin (ANI-1) for germ cell membrane stabilization and contractile ring formation in C.elegans germline cells. Cell division requires constriction of an actomyosin ring to segregate the genetic material equally into two daughter cells. The spatial and temporal regulation of the contractile ring at the division plane primarily depends on intracellular signals mediated by the centralspindlin complex and astral microtubules. Although much investigative work has elucidated intracellular factors and mechanisms controlling this process, the extracellular regulation of cytokinesis remains unclear. Thus far, the extracellular matrix protein Hemicentin (HIM-4) has been proposed to be required for cleavage furrow stabilization. The underlying molecular mechanism, however, has remained largely unknown. Here, we show that HIM-4 and anillin (ANI-1) genetically act in the same pathway to maintain the rachis bridge stability in the germline. Our FRAP experiments further reveal that HIM-4 restricts the motility of ANI-1. In addition, we demonstrate that HIM-4 is recruited to the cleavage site in dividing germ cells and promotes the proper ingression of the cleavage membrane. Collectively, we propose that HIM-4 is an extracellular factor that regulates ANI-1 for germ cell membrane stabilization and contractile ring formation in Caenorhabditis elegans germline cells.

Abstract
In order to achieve long-pulse H-mode plasma scenario over 400 s with high heating power in the Experimental Advanced Superconducting Tokamak (EAST) device, the lower graphite divertor will be upgraded into a tungsten (W) divertor with active water cooling, which consists of the W/Cu monoblock units and the W flat-tile units as the divertor plasma facing components. As a fundamental diagnostic tool, the divertor Langmuir probe (Div-LP) diagnostic system will be upgraded accordingly. This paper presents the design of two kinds of new Div-LP systems, which are planned to be utilized on the W/Cu monoblock units and the W flat-tile units for the upgraded lower tungsten divertor, respectively, including their structures and preliminary poloidal and toroidal layouts. The Div-LP diagnostic system can measure the plasma parameters with the schemes of triple-probe, double-probe, and single-probe, to obtain the spatial and temporal distribution of plasma behavior on the divertor targets, which is useful for the discharge control and operation in EAST. In addition, the thermal analysis of the two kinds of probe assemblies is also carried out by using the three-dimensional finite element code ANSYS, which is aimed to get the optimal designs to withstand the long-pulse and high-power operation in EAST future experiments.

Abstract
Objective: To explore the characteristics and methods of different fixation methods and prevention of open knee joint fracture. Methods: The data of 86 cases of open knee joint fracture admitted from January 2002 to December 2015 in Department of Orthopaedics, Affiliated Hospital of Chengdu University were analyzed retrospectively.There were 65 males and 21 females aged of 38.6 years. There were 38 cases treated with trans articular external fixation alone, 48 cases were in the trans articular external fixation plus auxiliary limited internal fixation group. All the patients were treated according to the same three stages except for different fixation methods. Observation of external fixation and fracture fixation, fracture healing, wound healing and treatment, treatment and related factors of infection control and knee function recovery. χ(2) test was used to analyze data. Results: Eleven patients had primary wound healing, accounting for 12.8%. Seventy-five patients had two wounds healed, accounting for 87.2%. Only 38 cases of trans articular external fixator group had 31 cases of articular surface reduction, accounting for 81.6%; Five cases of trans articular external fixator assisted limited internal fixation group had 5 cases of poor reduction, accounting for 10.4%; There was significant difference between the two groups (χ(2)=44.132, P<0.05). Take a single cross joint external fixation group, a total of 23 cases of patients with infection, accounted for 60.5% of external fixation group; trans articular external fixation assisted limited internal fixation group there were 30 cases of patients with infection, accounting for the assistance of external fixator and limited internal fixation group 62.5%; There was significant difference between the two groups(χ(2)=0.035, P>0.05). Five cases of fracture nonunion cases of serious infection, patients voluntarily underwent amputation. The Lysholm Knee Scale: In the external fixation group, 23 cases were less than 50 points, accounting for 60.5%, 15 cases were more than 50 points, accounting for 39.5%, external fixation and limited internal fixation group 20 cases were less than 50 points, accounting for 41.7%, 28 cases were more than 50 points, accounting for 58.3%; There was significant difference between the two groups(χ(2)=1.279, P>0.05). Conclusions: Prevention and control of infection is a central link in the treatment of open fracture of the knee. Trans articular external fixator plus limited internal fixation is an important measure to treat open fracture of the knee-joint.

Abstract
The Front Cover shows a novel rhodol‐based fluorescence probe from the structural combination of rhodamine and fluorescein motifs. Through the modification of the functional group on the spiro‐ring, high selectivity and sensitivity towards mercury(II) and hypochlorite ions are achieved, showing a significant color change and fluorescence enhancement. Confocal microscopy images of HeLa cells incubated with the probe show enhanced fluorescence intensity with HClO, thus demonstrating the potential of the probe in further applications for in vivo HOCl detection. More information can be found in the Full Paper by L. Li et al. on page 136 in Issue 2, 2018 (DOI: 10.1002/open.201700154).![]()

Abstract
Two sensors, 1 with a spirolactone group and 2 with a spirolactam group containing a phenyl isothiocyanate moiety, based on rhodol, were designed and synthesized in order to obtain materials with excellent optical properties for the detection of environmentally and biologically important Hg2+ and hypochlorous acid (HClO) ions. The crystal structure of 1 revealed two moieties, a rhodamine-like portion with a spirolactone and a fluorescein-like portion without a spirolactone. In the absence of analyte, 1 produced an optical output with a maximum absorption and emission at 475 and 570 nm, respectively, which was attributed to the fluorescein-like moiety without a spirolactone. In contrast, the rhodamine-like moiety containing a spirolactone was activated by the addition of H+ or Hg2+ ions, and 1 yielded new absorption and emission peaks at 530 and 612 nm, respectively. Further functionalization with a phenyl isothiocyanate group afforded 2, a fluorescent probe for HClO. High selectivity and sensitivity towards the hypochlorite ion were anticipated, owing to the stoichiometric and irreversible formation of a thiosemicarbazide group, which led to dramatic fluorescence responses. With good functionality at physiological pH, probe 2 was successfully used to image HClO in HeLa cells.

Abstract
OBJECTIVE To summarize the clinical outcome of totally thoracoscopic cardiac surgery for mitral valve replacement. METHODS Clinical data of 634 cases undergoing totally thoracoscopic cardiac surgery for mitral valve replacement from May 2004 to February 2016 in Department of Thoracoscopic Cardiacsurgery, Shanghai Yodak Cardiothoracic Hospital was analyzed retrospectively. There were 292 male and 342 female patients, aged from 17 to 68 years with a mean of (45±13) years. All the 634 patients had moderate-severe mitral valve stenosis and (or) incompetence, 263 patients had moderate-severe tricuspid valve incompetence, 356 patients had atrial fibrillation, 46 patients had left atrium thrombosis. Cardiopulmonary bypass was established with right femoral artery and a single 2 stage venus cannula in the right atrium. The ascending aorta was cross-clamped and the myocardium was protected by coronary perfusion with cold crystalloid cardioplegia. Totally thoracoscopic mitral valve replacement were performed. RESULTS Thirteen cases had incision expanded and 8 cases had conversions to sternotomy. Cardiopulmonary bypass and aortic cross-clamp time were (89±18) minutes and (51±12) minutes, respectively. Operation time was (3.1±1.2) hours. Mechanical ventilation time and intensive care unit stay were (17±6) hours and (27±8) hours, respectively. Postoperation drainage quantity was (390±70) ml. The hospital days was (9.2±2.1) days. There were 5 cases in-hospital deaths. Postoperative complications occurred in 42 cases (6.6%), including 18 cases of right hemoneumothorax, 12 cases of reoperation for bleeding, 3 cases of perivalvular leakage (reoperation was done in 1 patient), 3 cases of low cardiac output syndrome, 2 cases of acute renal failure, 2 cases of inferior vena cava injury, 1 case of right femoral artery thrombosis and liver injury, respectively. The mean duration of follow-up was (58±9) months in 608 cases, with a follow-up rate of 96.7% (608/629). Three patients had died during the period of follow-up caused by congestive heart failure (2 patients) and stroke (1 patient). Late complication among 605 survivors were 37 cases, including 32 cases of moderate tricuspid valve insufficiency, 3 cases of stroke, 1 case of perivalvular leakage and infective endocarditis, respectively.There was no reoperation during the period of follow-up. CONCLUSION Totally thoracoscopic cardiac surgery for mitral valve replacement is safe and effective, with unique superiority and clinical feasible.

Abstract
Salt stress is an important environmental condition limiting the agricultural production. The reprogram of protein expression is one of the strategies of plants to cope with salt stress. We have previously analyzed the photosynthesis, antioxidant and oxidative phosphorylation involved in the carbon metabolism and the redox metabolism in rice seedlings under salt stress. Here, we focused on the proteins involved in nitrogen metabolic response. As it was reported that the nitrite uptake was enhanced in Arabidopsis PII knock-out mutants, the down-regulation of P-II nitrogen sensing protein in rice probably contributes to the accumulation of amino acids under stress. In addition, the protein synthesis is limited by the decrease of related proteins, and more amino acids could be used as the compatible solute. Hence, our study indicates that the rearrangement of nitrogen metabolism under salt stress could accumulate more amino acids as the compatible solute rather than the components of proteins. This study provides information for an improved understanding of nitrogen metabolic response to salt stress in rice.

Abstract
The plant hormones gibberellins (GA) and abscisic acid (ABA) play important roles in plant development and stress responses. Here we report a novel A20/AN1-type zinc finger protein ZFP185 involved in GA and ABA signaling in the regulation of growth and stress response. ZFP185 was constitutively expressed in various rice tissues. Overexpression of ZFP185 in rice results in a semi-dwarfism phenotype, reduced cell size, and the decrease of endogenous GA3 content. By contrast, higher GA3 content was observed in RNAi plants. The application of exogenous GA3 can fully rescue the semi-dwarfism phenotype of ZFP185 overexpressing plants, suggesting the negative role of ZFP185 in GA biosynthesis. Besides GA, overexpression of ZFP185 decreased ABA content and expression of several ABA biosynthesis-related genes. Moreover, it was found that ZFP185, unlike previously known A20/AN1-type zinc finger genes, increases sensitivity to drought, cold, and salt stresses, implying the negative role of ZFP185 in stress tolerance. ZFP185 was localized in the cytoplasm and lacked transcriptional activation potential. Our study suggests that ZFP185 regulates plant growth and stress responses by affecting GA and ABA biosynthesis in rice.

Abstract
A multi-energy soft x-ray (ME-SXR) diagnostic has been built for electron temperature profile in the edge plasma region in Experimental Advanced Superconducting Tokamak (EAST) after two rounds of campaigns. Originally, five preamplifiers were mounted inside the EAST vacuum vessel chamber attached to five vertically stacked compact diode arrays. A custom mechanical structure was designed to protect the detectors and electronics under constraints of the tangential field of view for plasma edge and the allocation of space. In the next experiment, the mechanical structure was redesigned with a barrel structure to absolutely isolate it from the vacuum vessel. Multiple shielding structures were mounted at the pinhole head to protect the metal foils from lithium coating. The pre-amplifiers were moved to the outside of the vacuum chamber to avoid introducing interference. Twisted copper cooling tube was embedded into the back-shell near the diode to limit the temperature of the preamplifiers and diode arrays during vacuum vessel baking when the temperature reached 150 °C. Electron temperature profiles were reconstructed from ME-SXR measurements using neural networks.

Abstract
The plant-specific AWPM-19-domain proteins play important roles in plant development and stress responses. In the current study, OsPM19L1 encoding Oryza sativa AWPM-19-like protein 1 was isolated from rice. Tissue-specific gene expression analysis revealed that OsPM19L1 was highly expressed in the leaf sheath of rice. Interestingly, expression of OsPM19L1 was high at the early stage of panicle development and decreased thereafter. qRT-PCR analysis indicated that OsPM19L1 was dramatically induced by 20% PEG stress (>600-fold), exogenous abscisic acid (>350-fold), salt and cold stress. Subcellular localization assay suggested that the OsPM19L1-GFP (green fluorescent protein) fusion protein was localized in the membrane system in rice cells. Moreover, under stress conditions, OsPM19L1 expression was enhanced in an ABI5-Like1 (ABL1) deficiency rice mutant, abl1, suggesting that ABL1 negatively regulates OsPM19L1 gene expression. Thus, OsPM19L1 appears to be closely associated with stress tolerance through ABA-dependent pathway in rice.

Abstract
BACKGROUND Grain length, as a critical trait for rice grain size and shape, has a great effect on grain yield and appearance quality. Although several grain size/shape genes have been cloned, the genetic interaction among these genes and the molecular mechanisms of grain size/shape architecture have not yet to be explored. RESULTS To investigate the genetic interaction between two major grain length loci of rice, GS3 and qGL3, we developed two near-isogenic lines (NILs), NIL-GS3 (GS3/qGL3) and NIL-qgl3 (gs3/qgl3), in the genetic background of 93-11 (gs3/qGL3) by conventional backcrossing and marker-assisted selection (MAS). Another NIL-GS3/qgl3 (GS3/qgl3) was developed by crossing NIL-GS3 with NIL-qgl3 and using MAS. By comparing the grain lengths of 93-11, NIL-GS3, NIL-qgl3 and NIL-GS3/qgl3, we investigated the effects of GS3, qGL3 and GS3 × qGL3 interaction on grain length based on two-way ANOVA. We found that GS3 and qGL3 had additive effects on rice grain length regulation. Comparative analysis of primary panicle transcriptomes in the four NILs revealed that the genes affected by GS3 and qGL3 partially overlapped, and both loci might be involved in brassinosteroid signaling. CONCLUSION Our data provide new information to better understand the rice grain length regulation mechanism and help rice breeders improve rice yield and appearance quality by molecular design breeding.

Abstract
Salt stress is one of most serious limiting factors for crop growth and production. An isobaric Tags for Relative and Absolute Quantitation (iTRAQ) approach was used to analyze proteomic changes in rice shoots under salt stress in this study. A total of 56 proteins were significantly altered and 16 of them were enriched in the pathways of photosynthesis, antioxidant and oxidative phosphorylation. Among these 16 proteins, peroxiredoxin Q and photosystem I subunit D were up-regulated, while thioredoxin M-like, thioredoxin x, thioredoxin peroxidase, glutathione S-transferase F3, PSI subunit H, light-harvesting antenna complex I subunits, chloroplast chaperonin, vacuolar ATP synthase subunit H, and ATP synthase delta chain were down-regulated. Moreover, physiological data including total antioxidant capacity, peroxiredoxin activity, chlorophyll a/b content, glutathione S-transferase activity, reduced glutathione content and ATPase activity were consistent with changes in the levels of these proteins. The levels of the mRNAs encoding these proteins were also analyzed by real-time quantitative reverse transcription PCR, and approximately 86% of the results were consistent with the iTRAQ data. Importantly, our data suggest the important role of PSI in balancing energy supply and ROS generation under salt stress. This study provides information for an improved understanding of the function of photosynthesis and PSI in the salt-stress response of rice.

Abstract
The WW domain-containing oxidoreductase (WWOX) gene is a candidate tumor suppressor gene. However, its exact mechanism is unclear. This study aimed to investigate the role of the WWOX gene in the development of nasopharyngeal carcinoma (NPC). Tissues were collected from 65 NPC patients. Reverse transcriptase-polymerase chain reaction (RT-PCR) analysis and immunohistochemistry were performed on NPC tissues to determine the expression of WWOX in NPC. The status of WWOX promoter methylation was analyzed by methylation-specific PCR. Moreover, a PCR-based loss of heterozygosity (LOH) assay was conducted to detect the presence of WWOX deletion in NPC. The expression of WWOX in NPC tissues was significantly downregulated compared with that in non-tumorous tissues (P<0.05). The low expression of WWOX was significantly correlated with clinical TNM stage (P<0.05). In addition, methylation of WWOX was detected in 27 (87%) of 31 WWOX protein negative tissues, suggesting that methylation of the WWOX promoter may regulate its expression. We found that a relatively high percentage of LOH was observed in NPC tissues. A significant inverse correlation between WWOX expression and methylation of its promoter was found in NPC tissue (rs=-0.582, P=0.001). However, LOH was not correlated with WWOX expression and methylation of its promoter. Our results show that WWOX gene alteration is an early genetic alteration and may contribute to tumorigenesis of NPC. WWOX may be an important prognostic marker in NPC.

Abstract
The formulation of quercetin nanoliposomes (QUE-NLs) has been shown to enhance QUE antitumor activity in C6 glioma cells. At high concentrations, QUE-NLs induce necrotic cell death. In this study, we probed the molecular mechanisms of QUE-NL-induced C6 glioma cell death and examined whether QUE-NL-induced programmed cell death involved Bcl-2 family and mitochondrial pathway through STAT3 signal transduction pathway. Downregulation of Bcl-2 and the overexpression of Bax by QUE-NL supported the involvement of Bcl-2 family proteins upstream of C6 glioma cell death. In addition, the activation of JAK2 and STAT3 were altered following exposure to QUE-NLs in C6 glioma cells, suggesting that QUE-NLs downregulated Bcl-2 mRNAs expression and enhanced the expression of mitochondrial mRNAs through STAT3-mediated signaling pathways either via direct or indirect mechanisms. There are several components such as ROS, mitochondrial, and Bcl-2 family shared by the necrotic and apoptotic pathways. Our studies indicate that the signaling cross point of the mitochondrial pathway and the JAK2/STAT3 signaling pathway in C6 glioma cell death is modulated by QUE-NLs. In conclusion, regulation of JAK2/STAT3 and ROS-mediated mitochondrial pathway agonists alone or in combination with treatment by QUE-NLs could be a more effective method of treating chemical-resistant glioma.

Abstract
The plant-specific NAC (NAM, ATAF, and CUC)-domain proteins play important roles in plant development and stress responses. In this research, a full-length cDNA named ENAC1 (early NAC-domain protein induced by abiotic stress 1) was isolated from rice. ENAC1 possess one NAC domain in the N-terminus. Comparative time-course expression analysis indicated that ENAC1 expression, similar with OsDREB1A, was induced very quickly by various abiotic stresses including salt, drought, cold, and exogenous abscisic acid. However, the induction of ENAC1 by abiotic stress was transient and lasted up to 3 h, whereas that of OsDREB1A maintained longer. The promoter sequence of ENAC1 harbors several cis-elements including ABA response elements, but the well-known dehydration responsive element/C-repeat element is absent. The ENAC1-GFP (green fluorescent protein) fusion protein was localized in the nucleus of rice protoplast cell. Yeast hybrid assays revealed that ENAC1 was a transcription activator and bound to NAC recognition sequence (NACRS). Co-expression analysis suggested that ENAC1 co-expressed with a number of stress-related genes. Taken together, ENAC1 may be an early transcription activator of stress responses and function in the regulation of NACRS-mediated gene expression under abiotic stress.

Abstract
Theoretically the auscultatory method using Korotkoff sounds is more related to the maximum artery closure status, while the oscillometric method is more related to the overall artery closure status under the cuff. Therefore, the latter is less accurate than the former. This work introduces a new method, which is more accurate than the oscillometric method and suitable for automatic devices. To monitor the maximum artery closure status, a piezoelectric film sensor is attached to the skin just above the brachial artery and under the central section of the cuff where maximum cuff pressure is transferred to the arm. Using the waveform features obtained by this sensor, measurement errors of 0.7±2.5 and 1.27±4.53 mmHg were obtained for the systolic and diastolic pressure, respectively. These reflect small deviations from auscultatory clinical data.

Abstract
The TFIIIA-type zinc finger transcription factors are involved in plant development and abiotic stress responses. Most TFIIIA-type zinc finger proteins are transcription repressors due to existence of an EAR-motif in their amino acid sequences. In this work, we found that ZFP182, a TFIIIA-type zinc finger protein, forms a homodimer in the nucleus and exhibits trans-activation activity in yeast cells. The deletion analysis indicated that a Leu-rich region at C-terminus is required for the trans-activation. Overexpression of ZFP182 significantly enhanced multiple abiotic stress tolerances, including salt, cold and drought tolerances in transgenic rice. Overexpression of ZFP182 promotes accumulation of compatible osmolytes, such as free proline and soluble sugars, in transgenic rice. ZFP182 activates the expression of OsP5CS encoding pyrroline-5-carboxylate synthetase and OsLEA3 under stress conditions, while OsDREB1A and OsDREB1B were regulated by ZFP182 under both normal and stress conditions. Interestingly, site-directed mutagenesis assay showed that DRE-like elements in ZFP182 promoter are involved in dehydration-induced expression of ZFP182. The yeast two-hybrid assay revealed that ZFP182 interacted with several ribosomal proteins including ZIURP1, an ubiquitin fused to ribosomal protein L40. The in vivo and in vitro interactions of ZFP182 and ZIURP1 were further confirmed by bimolecular fluorescence complementation and His pull-down assays. Our studies provide new clues in the understanding of the mechanisms for TFIIIA-type zinc finger transcription factor mediated stress tolerance and a candidate gene for improving stress tolerance in crops.

Abstract
BACKGROUND AND PURPOSE The G protein-coupled receptor 119 (GPR119) mediates insulin secretion from pancreatic β cells and glucagon-like peptide 1 (GLP-1) release from intestinal L cells. While GPR119-mediated insulin secretion is glucose dependent, it is not clear whether or not GPR119-mediated GLP-1 secretion similarly requires glucose. This study was designed to address the glucose-dependence of GPR119-mediated GLP-1 secretion, and to explore the cellular mechanisms of hormone secretion in L cells versus those in β cells. EXPERIMENTAL APPROACH GLP-1 secretion in response to GPR119 agonists and ion channel modulators, with and without glucose, was analysed in the intestinal L cell line GLUTag, in primary intestinal cell cultures and in vivo. Insulin secretion from Min6 cells, a pancreatic β cell line, was analysed for comparison. KEY RESULTS In GLUTag cells, GPR119 agonists stimulated GLP-1 secretion both in the presence and in the absence of glucose. In primary mouse colon cultures, GPR119 agonists stimulated GLP-1 secretion under glucose-free conditions. Moreover, a GPR119 agonist increased plasma GLP-1 in mice without a glucose load. However, in Min6 cells, GPR119-mediated insulin secretion was glucose-dependent. Among the pharmacological agents tested in this study, nitrendipine, an L-type voltage-dependent calcium channel blocker, dose-dependently reduced GLP-1 secretion from GLUTag cells, but had no effect in Min6 cells in the absence of glucose. CONCLUSIONS AND IMPLICATIONS Unlike that in pancreatic β cells, GPR119-mediated GLP-1 secretion from intestinal L cells was glucose-independent in vitro and in vivo, probably because of a higher basal calcium tone in the L cells.

Abstract
PURPOSE. This study investigated human telomerase RNA gene (TERC) gain and polysomy of chromosome 3 in cervicovaginal liquid-based pap preparations in Guilin, China, and assessed the relationship between FISH findings and clinical diagnoses. METHODS. Slides prepared from 63 liquid-based preparations with cytologic diagnoses of negative for squamous intraepithelial lesion or malignancy (NILM n = 9), atypical squamous cells of undetermined significance (ASCUS, n = 18), low-grade squamous intraepithelial lesion (LSIL, n = 14), high-grade squamous intraepithelial lesion (HSIL, n = 9), and cervical squamous cell carcinoma (SCCA, n = 13) were analyzed for TERC gain and polysomy of chromosome 3 using a commercially available two-color FISH probe. The results of the cytologic analysis and those of concurrent or subsequent biopsies, when available, were compared with the FISH findings. The Mann-Whitney test was used to assess associations between FISH findings and diagnoses. RESULTS. TERC gain and polysomy of chromosome 3 were significantly associated with the cytologic diagnosis (p? 0.001). Patients with HSIL or SCCA cytology diagnoses had a significantly higher percentage of cells with TERC gain and polysomy of chromosome 3 than did patients with NILM, ASCUS or LSIL cytologic diagnoses. Those abnormal cases with CIN1 histological diagnosis had a significantly lower percentage of cells with TERC gain and polysomy of chromosome 3 than did patients with a CIN2, CIN3 and SCCA histological diagnosis. CONCLUSIONS. TERC gain and polysomy of chromosome 3 may be important associated genetic events in cervical intraepithelial neoplasia and carcinoma. FISH is a potential tool for the diagnoses of uterine cervix disease.

Abstract
BACKGROUND Patients with Crohn's disease have defects in intestinal epithelial permeability that are inadequately explained by known inflammatory bowel disease (IBD) susceptibility genes. E-cadherin (CDH1) plays a vital role in maintaining the integrity of the intestinal barrier and its cellular localisation is disrupted in patients with Crohn's disease. AIM To determine if polymorphisms in the CDH1 gene are associated with Crohn's disease and to determine the function associated with these polymorphisms. METHODS The hypothesis was tested using a candidate gene approach using 20 Tag SNPs derived from the HapMap and Crohn's disease trios. Functional studies were carried out using HapMap cell lines and polarised epithelial cell lines (MDCK-1 and Caco2). RESULTS Here we show that CDH1 is associated with Crohn's disease in 327 trios (rs10431923 excess transmission of "TT" genotype; p = 0.0020) and is replicated in the Wellcome Trust Case Control Consortium CD data set (TT risk allele; OR 1.2, p = 0.005). Patients with the Crohn's disease risk haplotype (rs12597188, rs10431923 and rs9935563; GTC allelic frequency 21%; p = 0.000016) exhibited increased E-cadherin cytoplasmic accumulation in their intestinal epithelium which may be explained by the presence of a novel truncated form of E-cadherin. Accordingly, expression of this truncated E-cadherin in cultured polarised epithelial cells resulted in abnormal intracellular accumulation and impaired plasma membrane localisation of both E-cadherin and beta-catenin. CONCLUSION The mis-localisation of E-cadherin and beta-catenin may explain the increased permeability seen in some patients with Crohn's disease. Thus, the polymorphisms identified in CDH1 are important for understanding the pathogenesis of Crohn's disease and point to a defect in barrier defence.

Abstract
Background and purpose: GPR119 is a G protein-coupled receptor that is preferentially expressed in islet cells and mediates insulin secretion. Oleoyl-lysophosphatidylcholine and oleoylethanolamide (OEA) act as endogenous ligands for this receptor, whereas PSN375963 and PSN632408 are two recently reported synthetic agonists. In this study, we explored mechanisms underlying GPR119-induced insulin secretion. In addition, we assessed the potential utility of the synthetic agonists as tools for exploring GPR119 biology. Experimental approach: We examined natural and synthetic GPR119 agonist activity at GPR119 in MIN6c4 and RINm5f insulinoma cells. We evaluated insulin secretion, intracellular calcium [Ca2+]i, ion channel involvement and levels of cAMP. Key results: We report that increases in insulin secretion induced by OEA were associated with increased cAMP and a potentiation of glucose-stimulated increases in [Ca2+]i. We also demonstrate that ATP-sensitive K+ and voltage-dependent calcium channels were required for GPR119-mediated increases in glucose-stimulated insulin secretion. In contrast to OEA, the synthetic GPR119 agonist PSN375963 and PSN632408 have divergent effects on insulin secretion, cAMP and intracellular calcium in MIN6c4 cells. Conclusions and implications: The endogenous ligand OEA signals through GPR119 in a manner similar to glucagon-like peptide-1 (GLP-1) and its receptor with respect to insulin secretion, [Ca2+]i and cAMP. In addition, PSN375963 and PSN632408 substantially differ from OEA and from one another. These studies suggest that the commercially available synthetic agonists, although they do activate GPR119, may also activate GPR119-independent pathways and are thus unsuitable as GPR119-specific pharmacological tools.
