Abstract
AIM To develop a simple and convenient method based on multiparametric magnetic resonance imaging (MRI) and clinical features to non-invasively predict tumour-infiltrating lymphocytes (TILs) in breast cancer (BC) and to explore the relationship between TIL levels and disease-free survival (DFS). MATERIALS AND METHODS A total of 172 BC patients were enrolled between November 2017 and June 2021 in this retrospective study. The patients were divided into high (≥10%) and low (<10%) TIL groups. Clinicopathological data were collected. MRI features were reviewed by two radiologists. Predictors associated with TILs were determined by using multivariable logistic regression analyses. Kaplan-Meier survival curves based on TIL levels were used to estimate DFS. RESULTS A total of 102 patients with low TILs and 70 patients with high TILs were included in the study. Tumour size (odds ratio [OR], 1.040; 95% confidence interval [CI]: 1.006, 1.075; p=0.020), apparent diffusion coefficient (ADC; OR, 1.003; 95% CI: 1.001, 1.005; p=0.015), clinical axillary lymph node status (CALNS; OR, 3.222; 95% CI: 1.372,7.568; p=0.007), and enhancement pattern (OR, 0.284; 95% CI: 0.143, 0.563; p<0.001) were independently associated with TIL levels. These features were used in the ALSE model (where A is ADC, L is CALNS, S is size, and E is enhancement pattern). High TILs were associated with better DFS (p=0.016). CONCLUSION The ALSE model derived from multiparametric MRI and clinical features could non-invasively predict TIL levels in BC, and high TILs were associated with longer DFS, especially in human epidermal growth factor receptor 2 (HER2)-positive BC and triple-negative BC (TNBC).

Abstract
AIM To develop an integrated model based on preoperative magnetic resonance imaging (MRI) features for predicting early recurrence in patients with triple-negative breast cancer (TNBC). MATERIALS AND METHODS Women with TNBC who underwent breast MRI and surgery between 2009 and 2019 were evaluated retrospectively. Two breast radiologists reviewed MRI images independently based on the Breast Imaging Reporting and Data System Lexicon (BI-RADS), and classified the breast oedema scores on T2-weighted imaging (WI) as no oedema, peritumoural oedema, prepectoral oedema, or subcutaneous oedema. The relationship between disease-free survival (DFS) and MRI features was analysed by Cox regression, and a nomogram model was generated based on the results. RESULTS 150 patients with TNBC were included and divided into a training cohort (n=78) and validation cohort (n=72). MRI features including subcutaneous oedema and rim enhancement showed a tendency to worsen DFS in univariate analysis. Multivariate analysis showed that subcutaneous oedema (p=0.049, HR [95% confidence interval {CI} = 8.24 [1.01-67.52]) and rim enhancement (p=0.016, HR [95% CI] = 4.38 [1.32-14.54]) were independent predictors for DFS. In the nomogram, the areas under the curves (AUCs) of the training cohort was 0.808, and that of the validation cohort was 0.875. CONCLUSION The presence of subcutaneous oedema or rim enhancement on preoperative breast MRI was shown to be a good predictor of poor survival outcomes in patients with TNBC.

Abstract
Lead-free halide perovskites have triggered interest in the field of optoelectronics and photocatalysis because of their low toxicity, and tunable optical and charge-carrier properties. From an application point of view, it is desirable to develop stable multifunctional lead-free halide perovskites. We have developed a series of Cs2 Ptx Sn1-x Cl6 perovskites (0≤x≤1) with high stability, which show switchable photoluminescence and photocatalytic functions by varying the amount of Pt4+ substitution. A Cs2 Ptx Sn1-x Cl6 solid solution with a dominant proportion of Pt4+ shows broadband photoluminescence with a lifetime on the microsecond timescale. A Cs2 Ptx Sn1-x Cl6 solid solution with a small amount of Pt4+ substitution exhibits photocatalytic hydrogen evolution activity. An optical spectroscopy study reveals that the switch between photoluminescence and photocatalysis functions is controlled by sub-band gap states. Our finding provides a new way to develop lead-free multifunctional halide perovskites with high stability.

Abstract
For display applications, it is highly desirable to obtain tunable red/green/blue emission. However, lead-free perovskite nanocrystals (NCs) generally exhibit broadband emission with poor color purity. Herein, we developed a unique phase transition strategy to engineer the emission color of lead-free cesium manganese bromides NCs and we can achieve a tunable red/green/blue emission with high color purity in these NCs. Such phase transition can be triggered by isopropanol: from one dimensional (1D) CsMnBr3 NCs (red-color emission) to zero dimensional (0D) Cs3 MnBr5 NCs (green-color emission). Furthermore, in a humid environment both 1D CsMnBr3 NCs and 0D Cs3 MnBr5 NCs can be transformed into 0D Cs2 MnBr4 ⋅2 H2 O NCs (blue-color emission). Cs2 MnBr4 ⋅2 H2 O NCs could inversely transform into the mixture of CsMnBr3 and Cs3 MnBr5 phase during the thermal annealing dehydration step. Our work highlights the tunable optical properties in single component NCs via phase engineering and provides a new avenue for future endeavors in light-emitting devices.

Abstract
BACKGROUND Long non-coding RNAs (lncRNAs) govern fundamental biochemical and cellular biology processes, for example, participate in chromatin remodeling, imprinting, splicing, transcriptional regulation and translation. Dysregulation of lncRNA expression is act as a feature of various diseases and cancers, including hematopoietic malignancies. However, the clinical relevance of myelodysplastic syndrome (MDS) and acute myeloid leukemia preceded by MDS (MDS-AML) requires further research. Recently, lncRNAs have been demonstrated, which play an important role in hematopoiesis, thus, to further finding more functional lncRNA seemed particularly important. METHODS Western blotting, real-time PCR, RNA-pulldown, RIP (RNA immunoprecipitation), Chromatin immunoprecipitation (ChIP), cellular compartments extraction assays, SA-β-gal staining, lentivirus transfection, cell viability assay and cell proliferation assays were used to examine the relationship between lncRNA LINC01255 and its regulation of p53-p21 pathway in human mesenchymal stromal and acute myeloid leukemia cells. RESULTS LncRNA LINC01255 is highly expressed in bone marrow cells of AML patients, CD34+ cells of MDS-AML patients and AML cell lines and the higher expression of LINC01255 is associated with poor survival rate of AML patients. LINC01255 can interact with BMI1 and repress the transcription of MCP-1 to active p53-p21 pathway, thus inhibiting the senescence of human mesenchymal stromal and proliferation of acute myeloid leukemia cell. CONCLUSIONS We discovered a novel functional lncRNA LINC01255, which can regulate the senescence of human mesenchymal stromal and the proliferation of acute myeloid leukemia cell through inhibiting the transcription of MCP-1.

Abstract
Objectives This study determined the rate of secondary infection among contacts of individuals with confirmed coronavirus disease 2019 (COVID-19) in Hangzhou according to the type of contacts, the intensity of contacts, and their relationship with the index patient. Study design This is a retrospective cohort study. Methods The analysis used the data of 2994 contacts of 144 individuals with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The contacts were categorized according to the information source, type of contact, location, intensity of contact, and relationship with the index patient. Results The incidence of infection differed significantly according to contact type. Of the contacts, 186 (6.2%) developed symptoms, and 71 (2.4%) had confirmed SARS-CoV-2 infection. The main symptoms were cough and fever. Compared with those who had brief contact with the index case, those who had dined with the index case had 2.6 times higher risk of acquiring infection; those who had shared transport with, had visited, or had contact with the index case in a medical institution had 3.6 times higher risk of acquiring infection; and household contacts had 41.7 times higher risk of acquiring infection. Family members had 31.6 times higher risk of acquiring infection than healthcare providers or other patients exposed to an index case. Conclusions The form and frequency of contact are the main factors affecting the risk of infection among contacts of individuals with COVID-19. Centralized isolation and observation of close contacts of individuals with confirmed SARS-CoV-2 infection, in addition to population-based control measures, can reduce the risk of secondary infections and curb the spread of the infection. The incidence of infection differed significantly according to contact type. Contact form and frequency are important to the risk of COVID-19. Centralized isolation and observation of contacts curbed the spread of the infection.

Abstract
A self-powered origami paper-based analytical device (oPAD), being with a pop-up structure as mechanical valve to first realize dual-mode of differential pulse voltammery (DPV)/supercapacitor amplified signal read out systems, was designed for detecting adenosine 5'-triphosphate (ATP) assisted by glucose oxidase (GOx)-triggered reaction. In order to accommodate the alternative step for dual-mode detection, a pop-up structure inspired by pop-up greeting cards was developed, making it possible to change the fluidic path with good registration and repeatability. To realize supercapacitor detection mode, a sandwich structure of a DNA sequence (DNA1), aptamer and a DNA sequence modified with GOx (GOx-DNA2) was formed on detection zone by hybridization reaction. With the addition of ATP, the GOx-DNA2 could be released with the specific binding between ATP and aptamer, and flowed into the reaction zone to catalyze the oxidation of glucose. Due to the difference in concentrations of [Fe(CN)6]3- and [Fe(CN)6]4- caused by the GOx-triggered reaction, a voltage could be produced to charge a paper supercapacitor which could provide a high instantaneous current with a digital multimeter to transduce the result of the assay, and realize the self-generation of an amplified electrical signal. By simply varying the direction of pop-up structure, the electrochemical signal from DPV read out mode could be achieved through catalytic oxidation of glucose by the remaining GOx-DNA2 on the detection zone. The proposed self-powered oPAD enabled the sensitive diagnosis of ATP in a linear range of 10-5000 nM with a limit of detection of 3 nM and 1.4 nM, respectively.

Abstract
Objective: To estimate the immune memory at 12 years after hepatitis B vaccination and its risk factors among adults. Methods: The study was conducted in 20 villages of Qudi town in Jiyang county, Shandong province, China in 2003. Hepatitis B surface antigen (HBsAg), antibody against HBsAg (anti-HBs) and antibody against hepatitis B core antigen (anti-HBc) were tested for all healthy residents aged 15-40 years in these villages. Those who had no history of hepatitis B vaccination and were negative for all three indicators were divided into two groups randomly. Hepatitis B vaccine (HepB) was administrated to them on 0-6 month schedule or 0-1-6 month schedule respectively. Blood samples were obtained at one month after the last dose for each receipt and were quantitatively detected for anti-HBs. Finally a total of 629 participants completed HepB vaccination and anti-HBs testing, including 288 of two-dose group and 341 of three-dose group respectively. In 2015, an additional dose of HepB (challenge dose) was administrated to those who were negative for anti-HBs at follow-up (anti-HBs <10 mIU/ml) to evaluate the immune memory. A total of 93 blood samples, including 50 of two-dose group and 43 of three-dose group respectively, were drawn at 14 days after the challenge dose and anti-HBs was quantitatively detected. The anti-HBs geometric mean concentrations (GMCs) after the challenge dose were compared between the two groups. Multivariate linear regression model was built to find the independent risk factors associated with immune memory response (anti-HBs GMC after the challenge dose). Results: The challenge dose of HepB and post-challenge anti-HBs detection were completed among 93 participants. Totally 92 (98.92%, 92/93) participants were found holding immune memory (anti-HBs after the challenge dose was ≥10 mIU/ml). The immune memory positive rates were 100% (50/50) and 97.67% (42/43) in the two-dose group and three-dose group respectively and the corresponding anti-HBs GMC after challenge dose were 2 684.30 (95%CI: 1 721.71-4 185.08) mIU/ml and 3 527.48 (95%CI: 2 145.15-5 800.58) mIU/ml (P=0.410). The anti-HBs GMC after the challenge dose were 1 908.33 (95%CI: 1 190.01-3 060.27) mIU/ml, 4 004.20 (95%CI: 2 257.90-7 101.12) mIU/ml and 8 682.16 (95%CI: 5 813.94-12 965.36) mIU/ml among the participants whose anti-HBs titer was<4, 4-6 and 7-9 mIU/ml at follow-up, respectively (P=0.002). There was no correlation between immune schedule and anti-HBs GMC after the challenge dose; β (95%CI) was -0.07 (-0.34-0.20), P=0.601. Conclusion: The immune memory after primary hepatitis B vaccination lasted for at least 12 years among adults. The immune memory response was independently associated with ant-HBs titer at follow-up, but might be similar between 0-6 month schedule and 0-1-6 month schedule.

Abstract
An effective "on-off-on" photoelectrochemical (PEC)/visual sensing system based on cleaning-switchable lab-on-paper device was designed to achieve ultrasensitive detection of analytes. The first amplified "signal-on" PEC state was gained by CdS quantum dots sensitized leaf-shape ZnO (CdS QDs/leaf-shape ZnO) structure, which was assembled on reduced graphene oxide (rGO) modified paper electrode. Then Au-modified prism-anchored octahedral CeO2 nanoparticles (Au@PO-CeO2 NPs), as an efficient signal quencher, were immobilized on the CdS QDs/leaf-shape ZnO with the assistance of DNA hybridization, resulting in a noticeable photocurrent response decrement with the "signal-off" PEC state. With the addition of analytes, the quencher Au@PO-CeO2 NPs were immediately released from the sensing surface and robust PEC response was recovered to the signal-on state again. Meanwhile, the disengaged quencher in electrolyte solution flowed to the colorimetric detection area of lab-on-paper device and catalyzed oxidation of the chromogenic substrate 3,3',5,5'-tetramethylbenzidine in the presence of H2O2 to form the colored product, making the analytes detection more convincing with the visual discrimination. Under optimal conditions, the proposed PEC/visual lab-on-paper device possessed the detection limits toward adenosine and potassium ion as low as 0.15 and 0.06 nM, respectively. With ingenious design of actuating conversion process between hydrophilicity and hydrophobicity by slipping paper tab to solve cleaning issue in the assay procedures, the cleaning-switchable lab-on-paper device was constructed for high-performance biosensing applications. It provides an unambiguous simplicity and portable operation for exploring high reliability and sensitivity of novel point-of-care diagnostic tool with dual-signal readout.

Abstract
AIMS Aspergillus aculeatus, a pathogen of peaches, can cause soft rot and lead to economic losses in agricultural production. However, studies on the prevention of soft rot caused by A. aculeatus have rarely been reported. Tricyclazole (TCZ) is a fungicide that has been widely used in disease prevention of various crops but the inhibitory mechanism of TCZ on A. aculeatus is unknown. Our aim was to determine the effects of TCZ on A. aculeatus. METHODS AND RESULTS In our study, TCZ inhibited the growth of fungal colonies when applied at 0·5-6 mmol l-1 and inhibited the production of melanin at 3 mmol l-1 . Conidia exposed to TCZ were less effective at causing the disease in inoculated samples, and electrical conductivity, divulgation of nucleic acids and proteins rose with increasing concentrations of TCZ. Microscopic results suggest that TCZ damages not only the cell wall but also the cell membrane. Results of qRT-PCR showed that TCZ had no significant effect on the regulation of genes coding for laccase, apoptosis and hypothetical protein; however, it significantly down-regulated genes coding for cellulase, chitinase and sterol. CONCLUSIONS Tricyclazole can influence the pathogenic ability of A. aculeatus by damaging the cell structure of hyphae and conidia, reducing the melanin production, and altering the expression of pathogenic-related gene. SIGNIFICANCE AND IMPACT OF THE STUDY The results explained the potential cause and mechanism TCZ produced in A. aculeatus. Our research offers scientific insights into future research interest relative to using TCZ in the treatment of soft rot caused by A. aculeatus.

Abstract
Sperm-mediated gene transfer(SMGT) is a simple method for producing transgenic animals. Due to the lack of repeatability in spermatozoa binding and internalization of exogenous DNA, the efficiency of SMGT is still low. Considering this point, the present work aims to develop a method for evaluating the spermatozoa capacity of binding exogenous DNA after co-incubation with DNA. The main approach is using a Cy5-labelled DNA to trace the exogenous DNA and assess the ability of spermatozoa to take up exogenous DNA. Using this technique, we found that the percentage of spermatozoa that are binding and uptaking DNA is higher at concentration of 10 μg/mL and 100 μg/mL than 5 μg/mL, 1 μg/mL and 0 μg/mL after incubation with Cy5-DNA for 30min at 37oC. After fertilization, the DNA fluorescence signal was also detected in zygotes in groups where spermatozoa were incubated with 10 μg/mL and 100 μg/mL of Cy5-DNA. These results showed a simple and convenient method to trace the exogenous DNA in spermatozoa and zygote when compared to conventional methods of labeling DNA during fertilization, resulting in a real-time observation of the exogenous DNA in spermatozoa and zygote.

Abstract
A microfluidic paper-based analytical device (μPAD) was simply constructed for highly sensitive detection of L-glutamic acid and L-cysteine. The μPAD featured with two functional zones on one strip of paper achieved by preferable multi-plate ZnO nanoflowers (ZnO NFs) and molecularly imprinting polymer (MIP) membranes. The as-designed μPAD was established based on the inherent relation between the photo-oxidation products and photoelectrochemical (PEC) performance with the highly sensitive detection of biomolecules. The ZnO NFs were utilized to produce photo-oxidation products by driving the reaction between ferrocenemethanol and photogenerated holes under ultraviolet light. The photo-oxidation products easily flowed to MIP membranes along the hydrophilic channel via capillary action. MIP membranes as the receptors specifically recognized the analytes as well as decreased the electron loss by blocking the reduction reaction between electrons and photo-oxidation products. The PEC response was obtained in the processes of electrons transfer and exhibited the direct relationships corresponding to the concentrations of target analytes. The μPAD showed the detection limits toward L-glutamic acid and L-cysteine as low as 9.6 pM and 24 pM, respectively. Moreover, it is interesting to point out that ZnO NFs nanostructure shows superior PEC signal compared with those of ZnO nanospheres, nanosheets, and nanorod arrays. In current work, photo-oxidation products are utilized to achieve highly sensitive PEC detection for biomolecules under ultraviolet light as well as avoid the effects of multiple modifications in the same region on the reproducibility, which is beneficial for opening up rich possibility for designing more efficient analytical strategy.

Abstract
A highly selective two-point separation strategy was designed based on a cross-like all-in-one lab-on-paper analytical device. The stable and cleavable enzyme-coated reduced graphene oxide (rGO)-PdAu probe was fabricated as the signal reporter to enable the visualization and electrochemiluminescence (ECL) dual-mode sensing of Pb2+. Concretely, the experimental workflow consists of the following process: (i) fabrication of the lab-on-paper device and growth of Au nanoparticles on ECL detection zone, (ii) immobilization of Pb2+-specific DNAzyme, and (iii) hybridization between DNAzyme and rGO-PdAu-glucose oxidase (GOx) labeled oligonucleotide to form the double-stranded DNA. Upon addition of Pb2+ into the prepared system, the double-helix structure of the DNA was destroyed, resulting in the release of cleaved rGO-PdAu-GOx probe to visualization bar to promote the effective oxidation and color change of 3,3',5,5'-tetramethylbenzidine. As a consequence, the color change can be recognized by naked eye, meanwhile GOx on an uncleaved signal probe can oxidize glucose along with the H2O2 production. As a co-reaction reagent for luminol ECL system, the concentration of H2O2 is proportional to the ECL intensity, which constitutes a new mechanism for colorimetric and ECL dual mode to detect Pb2+. With the method developed here, the concentration of Pb2+ could be easily determined by the naked eye within a linear range from 5 to 2000 nM, as well as by monitoring the decreased ECL intensity of luminol in a linear range of 0.5-2000 nM. This work not only constructs a simple and versatile platform for on-site visible monitoring of Pb2+ in tap water and river water but also furnishes a strategy for designing a dual-mode sensing toward different heavy metal ions based on specific DNAzyme in the fields of environmental monitoring-related technologies.

Abstract
Objective: To evaluate prevalence of hepatitis A antibody (anti-HAV IgG) among population covered by different hepatitis A vaccine immunization strategies in Shandong Province in 2015. Methods: In October 2015, according to the geographical location of Shandong Province, the stratified random sampling method was used to stratify the 17 municipal distrcts, and the random number table method was used for sampling, First, two eastern cites (Qingdao, Rizhao), two western cities (Liaocheng, Zaozhuang) and three central cities (Jinan, Zibo and Laiwu) were selected; secondly, one county was drawn from each city. Finally, the participants were divided into five age groups including ≤7 years (age group covered by free hepatitis A vaccination strategy), 8-11 years (age group who receive hepatitis A vaccination at their own charge), 12-24 years (age group covered by catch-up vaccination of hepatitis A), 25-34 years (age group born before hepatitis A vaccine was used) and ≥35 years (age group born before hepatitis A vaccine was used). After all the paticipants or their guardians asked and registered basic information such as age, gender, home address, blood samples were collected from them and anti-HAV IgG was detected by ELISA method. The positive rate of anti-HAV IgG and 95%CI were calculated. Results: A total of 1 654 participants were involved in the final analysis, including 856 males (51.75%) and 798 females (48.25%) whose mean age was (13.44±13.06) years. The crude positive rate of anti-HAV IgG was 91.41% (1 512/1 654, 95%CI: 89.96%-92.72%) and the age-adjusted rate was 90.93% (95%CI: 90.92%-90.94%). The positive rates of anti-HAV IgG was at the highest level in the age group of ≤7 years (95.90%, 95%CI: 95.88%-95.91%) and was at the lowest level in the age group of 25-34 years (83.23%, 95%CI: 83.21%-83.25%). The age-specific positive rates of anti-HAV IgG in eastern areas (96.79%, 95%CI: 96.78%-96.80%) were higher than those in both middle areas (86.66%, 95%CI: 86.65%-86.67%) and western areas (91.96%, 95%CI: 91.95%-91.97%). Conclusion: The positive rate of anti-HAV IgG was high among the general population in Shandong Province, but relatively low among young and middle-aged adults. Besides the routine immunization of hepatitis A among the children, more efforts should be taken for the prevention and control of hepatitis A among young and middle-aged adults in Shandong Province, especially in central and western areas.

Abstract
The clinical efficacy of reduction and fusion surgery and the suitable range of fusion-segment were evaluated in 12 pediatric patients treated for high-grade spondylolisthesis. Pre/post-operative clinical and radiological assessments were analyzed. A transient L5 nerve root paralysis was observed in one patient with L5 spondylolisthesis. No degenerative spondylolisthesis or adjacent segmental instability occurred above the fusion segments. In conclusion, we suggest that, in case of spondylolisthesis without severe structural scoliosis deformity or only associated with lumbosacral deformity, the posterior ligament complex should be protected in case of adjacent segmental instability and spondylolisthesis. If the spondylolisthesis is complicated with severe structural scoliosis deformity (Cobb ≥ 70°), in principle, the treatment should be performed according to the characteristics of the two diseases respectively.

Abstract
To find an efficient transfection method for metastatic cancer cells, we established a three-dimensional (3D) growth model for solid tumor cells to mimic the metastatic cancer cells in the vascular system and compared the efficiency of several transfection methods in vitro. We found that it was optimal to transfect two-dimensional cells in vitro and detach them for 3D growth 6 h later. The transfection efficiency of this method was high, and the results were reliable. This method can be used to deliver several types of small molecules into the 3D metastatic cell model. Using this method, we increased our understanding of why drugs that are effective in vitro cannot treat the disease in vivo. If this phenomenon occurs due to the resistance of the cells to the drug, other treatment agents for the disease must be identified. However, if this occurs because the agent cannot reach the cells inside the 3D aggregate, we can improve the delivery efficiency by using methods that target the agent to all cells. Briefly, the method introduced in this study will contribute to future research focusing on the 3D metastatic cell model as well as on drug development for various solid tumors.

Abstract
A chemiluminescence excited photoelectrochemical (PEC) competitive immunosensor for sensitive and specific detection of the prostate specific antigen (PSA) is firstly developed by combining a microfluidic paper-based device. Firstly, porous ZnO spheres with large surface area and good biocompatibility are attached onto the Au nanoparticle modified paper working electrode, which serve as an effective matrix for antigens. CdS nanorods (NRs) are selected as the photoactive materials due to their excellent fast and long distance electron transport capability, which allow the binding of the horseradish peroxidase-labeled signal antibody onto CdS NRs (CdS NR-Ab-HRP). After a competitive immunoassay format, the CdS NR-Ab-HRP labels are captured onto the electrode surface. The chemiluminescent excitation is produced from the oxidation of luminol by H2O2 in the presence of HRP. The more antigens in solution can bind to CdS NR-Ab-HRP the less CdS NR-Ab-HRP can bind to antigens immobilized on the electrode, which result in the decrease of chemiluminescence emission and light absorption, leading to the decrease of photocurrent intensity. The PEC response from CdS NR-Ab-HRP successfully fulfilled the sensitive detection of PSA in the linear range from 0.005 to 150 ng mL-1 with a detection limit of 2.3 pg mL-1. The proposed immunosensor shows excellent analytical performance with high reproducibility and stability, and can become a promising platform for other protein detection.

Abstract
The detection of cancer cells is important and fundamental for cancer diagnosis and therapy, which has attracted considerable interest recently. Although traditional cyto-sensors have been widely explored due to their high sensitivity and selectivity, it is still a challenge to develop a low-cost, portable, disposable, fast, and easy-to-use cancer cell detection method for applying in the field of cancer diagnosis and therapy. Herein, to address these challenges, we developed a microfluidic paper-based electrochemiluminescence origami cyto-device (μ-PECLOC), in which aptamers modified 3D macroporous Au-paper electrodes were employed as the working electrodes and efficient platforms for the specific cancer cells capture. Owing to the effective disproportionation of hydrogen peroxide and specific recognition of mannose on cell surface, concanavalin-A conjugated porous AuPd alloy nanoparticles were introduced into this μ-PECLOC as the catalytically promoted nanolabels for peroxydisulfate ECL system. Under the optimal conditions, the proposed μ-PECLOC exhibited excellent analytical performance with good stability, reproducibility, and accuracy, towards the cyto-sensing of four types of cancer cells indicating the potential applications to facilitate effective and multiple early cancer diagnosis and clinical treatment.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is an inducer of cancer cell death that holds promise in cancer therapy. Cancer cells are more susceptible than normal cells to the cell-death-inducing effects of TRAIL. However, a variety of cancer cells are resistant to TRAIL through complex mechanisms. Here, we investigate the effects of inhibition of eukaryotic initiation factor 2 subunit α (eIF2α) dephosphorylation on TRAIL-induced apoptosis in hepatoma cells. Treatment of hepatoma cells with salubrinal, an inhibitor of eIF2α dephosphorylation, enhances TRAIL-induced eIF2α phosphorylation, CCAAT/enhancer-binding protein homologous protein (CHOP) expression and caspase activation. Salubrinal enhances TRAIL-induced apoptosis, which could be abrogated by caspase inhibitor. Overexpression of phosphomimetic eIF2α (S51D) enhances TRAIL-induced CHOP expression, caspase 7 and PARP cleavage and apoptosis. By contrast, overexpression of phosphodeficient eIF2α (S51A) abrogates the stimulation of TRAIL-induced apoptosis by salubrinal. Moreover, knockdown of growth arrest and DNA damage-inducible protein 34 (GADD34), which recruits protein phosphatase 1 to dephosphorylate eIF2α, enhances TRAIL-induced eIF2α phosphorylation, CHOP expression, caspase activation and apoptosis. Furthermore, the sensitization of hepatoma cells to TRAIL by salubrinal is dependent on CHOP. Knockdown of CHOP abrogates the stimulation of TRAIL-induced caspase activation and apoptosis by salubrinal. Combination of salubrinal and TRAIL leads to increased expression of Bim, a CHOP-regulated proapoptotic protein. Bim knockdown blunts the stimulatory effect of salubrinal on TRAIL-induced apoptosis. Collectively, these findings suggest that inhibition of eIF2α dephosphorylation may lead to synthetic lethality in TRAIL-treated hepatoma cells.

Abstract
OBJECTIVE We hypothesize that intervertebral disc (IVD) cells from distinct region respond differently to oxygen environment, and that IVD cells from patients with disc degeneration can benefit from hypoxia condition. Therefore, we aimed to determine the transcriptional response and extracellular matrix (ECM) production of nucleus pulposus (NP) and annulus fibrosus (AF) cells to different oxygen tension. METHOD Human NP and AF from degenerated IVD were seeded in 3D scaffolds and subjected to varying oxygen tension (2% and 20%) for 3 weeks. Changes in ECM were evaluated using quantitative real-time reverse transcriptase polymerase chain reaction, histological and immunohistological analyses. RESULTS Hypoxia significantly enhances NP cells phenotype, which resulted in greater production of sulfated glycosaminoglycan (GAG) and collagen type II within the constructs and the cells expressed higher levels of genes encoding NP ECM. A significantly stronger fluorescent signal for hypoxia-inducible factor (HIF-1α) as also found in the NP cells under the hypoxic than normoxic condition. However, there was little effect of hypoxia on the AF cells. CONCLUSIONS The NP and AF cells respond differently to hypoxia condition on the 3D scaffold, and hypoxia could enhance NP phenotype. When used in concert with appropriate scaffold material, human NP cells from degenerated disc could be regenerated for tissue engineering application.

Abstract
Glutamate is the major mediator of excitotoxic neuronal death following cerebral ischemia. Under severe ischemic conditions, glutamate transporters can functionally reverse to release glutamate, thereby inducing further neuronal injury. Hypothermia has been shown to protect neurons from brain ischemia. However, the mechanism(s) involved remain unclear. Therefore, the aim of this study was to investigate the mechanism(s) mediating glutamate release during brain ischemia-reperfusion injury under hypothermic conditions. Neuron/astrocyte co-cultures were exposed to oxygen-glucose deprivation (OGD) at various temperatures for 2h, and cell viability was assayed 12h after reoxygenation. PI and MAP-2 staining demonstrated that hypothermia significantly decreased neuronal injury. Furthermore, [(3)H]-glutamate uptake assays showed that hypothermia protected rat primary cortical cultures against OGD reoxygenation-induced injury. Protein levels of the astrocytic glutamate transporter, GLT-1, which is primarily responsible for the clearance of extracellular glutamate, were also found to be reduced in a temperature-dependent manner. In contrast, expression of GLT-1 in astrocyte-enriched cultures was found to significantly increase following the addition of neuron-conditioned medium maintained at 37 °C, and to a lesser extent with neuron-conditioned medium at 33 °C. In conclusion, the neuroprotective effects of hypothermia against brain ischemia-reperfusion injury involve down-regulation of astrocytic GLT-1, which mediates the reverse transport of glutamate. Moreover, this process may be regulated by molecules secreted by stressed neurons.
