Abstract
Gibberellin A3 (GA3) is often used as a principal growth regulator to increase plant size. Here, we applied Tween-20 (2%)-formulated GA3 (T1:40 mg/L; T2:70 mg/L) by dipping the clusters at the initial expansion phase of 'Red Globe' grape (Vitis vinifera L.) in 2018 and 2019. Tween-20 (2%) was used as a control. The results showed that GA3 significantly increased fruit cell length, cell size, diameter, and volume. The hormone levels of auxin (IAA) and zeatin (ZT) were significantly increased at 2 h (0 d) -1 d after application (DAA0-1) and remained significantly higher at DAA1 until maturity. Conversely, ABA exhibited an opposite trend. The mRNA and non-coding sequencing results yielded 436 differentially expressed mRNA (DE_mRNAs), 79 DE_lncRNAs and 17 DE_miRNAs. These genes are linked to hormone pathways like cysteine and methionine metabolism (ko00270), glutathione metabolism (ko00480) and plant hormone signal transduction (ko04075). GA3 application reduced expression of insensitive dwarf 2 (GID2, VIT_07s0129g01000), small auxin-upregulated RNA (SAUR, VIT_08s0007g03120) and 1-aminocyclopropane-1-carboxylate synthase (ACS, VIT_18s0001g08520), but increased SAUR (VIT_04s0023g00560) expression. These four genes were predicted to be negatively regulated by vvi-miR156, vvi-miR172, vvi-miR396, and vvi-miR159, corresponding to specific lncRNAs. Therefore, miRNAs could affect grape size by regulating key genes GID2, ACS and SAUR. The R2R3 MYB family member VvRAX2 (VIT_08s0007g05030) was upregulated in response to GA3 application. Overexpression of VvRAX2 in tomato transgenic lines increased fruit size in contrast to the wild type. This study provides a basis and genetic resources for elucidating the novel role of ncRNAs in fruit development.

Abstract
Introduction The Tarlov cysts are pathological enlargements of the cerebrospinal fluid spaces between the endoneurium and perineurium, which can cause intolerable sciatic pain, motor impairment of lower limbs, and bladder/bowel dysfunction. Currently, the treatment results are unsatisfactory due to the low cure rates and extensive surgical trauma. Thus, there is an ongoing exploration of surgical techniques for Tarlov treatment. In the current study, we present a novel neuroendoscopic-assisted technique that combines the fenestration, leakage sealing, and tamponade of the Tarlov cyst. Methods Between January 2020 and December 2021, a total of 32 Tarlov patients were enrolled and received neuroendoscopic-assisted surgery. Their pre- and post-surgical Visual Analogue Scale (VAS) scores, major complaints, and MR imaging were recorded for comparison. Results 27 of 32 patients (84.4%) patients demonstrated immediate pain relief as their VAS scores decreased from 5.6 ± 1.5 to 2.5 ± 1.1 (p < 0.01) on the first day after surgery. At the 3-month follow-up, the patients' average VAS score continued to decrease (1.94 ± 0.8). Meanwhile, saddle paresthesia, urinary incontinence, and constipation were relieved in 6 (50%), 4 (80%), and 5 (41.7%), respectively, according to patients self-report. No surgical-related complication was observed in any of the cases. Discussion We conclude that neuroendoscopic-assisted surgery is an effective surgical method for symptomatic Tarlov cysts with minimized complications.

Abstract
Objective: To explore the status of turnover intention and its influencing factors of hemato-oncology nurses. Methods: From September to November 2021, the convenience sampling method was used to select 382 hemato-oncology nurses from 8 tertiary grade A general hospitals in Shandong Province. The general information questionnaire, the Chinese Nurses' Work Stressor Scale, the Psychological Capital Questionnaire and the Turnover Intention Questionnaire were used to investigate the general situation, occupational stress, psychological capital and turnover intention of the objects. The correlations between the turnover intention, occupational stress and psychological capital of the objects were analyze by Pearson correlation. And the multiple linear regression was used to analyze the influencing factors of turnover intention. A structural equation model was used to analyze the effect path of occupational stress and psychological capital on turnover intention. Results: The total turnover intention score of hemato-oncology nurses was (14.25±4.03), with the average item score of (2.38±0.67). The occupational stress score of hemato-oncology nurses was (71.57±14.43), and the psychological capital score was (91.96±15.29). The results of correlation analysis showed that the turnover intention of hemato-oncology nurses was positively correlated with occupational stress, and was negatively correlated with psychological capital (r=0.599, -0.489, P<0.001). Multiple linear regression analysis showed that married (β=-0.141), psychological capital (β=-0.156) and occupational stress (β=0.493) were the influencing factors of turnover intention of hemato-oncology nurses (P<0.05). The path analysis of structural equation model showed that the direct effect of occupational stress on turnover intention of hemato-oncology nurses was 0.522, and the intermediary effect of psychological capital on turnover intention was 0.143 (95%CI: 0.013-0.312, P<0.05), accounting for 21.5% of the total effect. Conclusion: The turnover intention of hemato-oncology nurses is at a high level, hospital and administrators should focus on the psychological state of unmarried nurses. By improving the psychological capital of nurses, to reduce occupational stress and turnover intention.

Abstract
The emergence of metallo-β-lactamases (MBLs) confers resistance to nearly all the β-lactam antibiotics, including carbapenems. Currently, there is a lack of clinically useful MBL inhibitors, making it crucial to discover new inhibitor chemotypes that can potently target multiple clinically relevant MBLs. Herein we report a strategy that utilizes a metal binding pharmacophore (MBP) click approach to identify new broad-spectrum MBL inhibitors. Our initial investigation identified several MBPs including phthalic acid, phenylboronic acid and benzyl phosphoric acid, which were subjected to structural transformations using azide-alkyne click reactions. Subsequent structure-activity relationship analyses led to the identification of several potent broad-spectrum MBL inhibitors, including 73 that manifested IC50 values ranging from 0.00012 μM to 0.64 μM against multiple MBLs. Co-crystallographic studies demonstrated the importance of MBPs in engaging with the MBL active site anchor pharmacophore features, and revealed the unusual two-molecule binding modes with IMP-1, highlighting the critical role of flexible active site loops in recognizing structurally diverse substrates/inhibitors. Our work provides new chemotypes for MBL inhibition and establishes a MBP click-derived paradigm for inhibitor discovery targeting MBLs as well as other metalloenzymes.

Abstract
Targeting MDM2-p53 interaction has emerged as a promising antitumor therapeutic strategy. Several MDM2-p53 inhibitors have advanced into clinical trials, but results are not favorable. The lack of appropriate biomarkers for selecting patients has been assumed as the critical reason for this failure. We previously identified ZER6 isoform p52-ZER6 as an oncogene upregulated in tumor tissues. In this study we investigated whether p52-ZER6 acted as a blocker of MDM2-p53 binding inhibitors, and whether p52-ZER6 could be used as a biomarker of MDM2-p53 binding inhibitors. In p53 wild-type colorectal carcinoma HCT116, hepatocarcinoma HepG2 and breast cancer MCF-7 cells, overexpression of p52-ZER6 enhanced MDM2-p53 binding and promoted p53 ubiquitination/proteasomal degradation. Furthermore, overexpression of p52-ZER6 in the tumor cells dose-dependently reduced their sensitivity to both nutlin and non-nutlin class MDM2-p53 binding inhibitors. We showed that p52-ZER6 restored tumor cell viability, which was suppressed by nutlin-3, through restoring their proliferation potential while suppressing their apoptotic rate, suggesting that MDM2-p53 binding inhibitors might not be effective for patients with high p52-ZER6 levels. We found that nutlin-3 treatment or p52-ZER6 knockdown alone promoted the accumulation of p53 protein in the tumor cells, and their combinatorial treatment significantly increased the accumulation of p53 protein. In HCT116 cell xenograft nude mouse model, administration of shp52-ZER6 combined with an MDM2-p53 binding inhibitor nutlin-3 exerted synergistic antitumor response. In conclusion, this study reveals that p52-ZER6 might be a potential biomarker for determining patients appropriate for MDM2-p53 binding inhibition-based antitumor therapy, and demonstrates the potential of combinatorial therapy using MDM2-p53 binding inhibitors and p52-ZER6 inhibition.

Abstract
Objective: The programmed death receptor 1/programmed death ligand 1 (PD-1/PD-L1) pathway can negatively regulate the immune response of the body, and serum soluble PD-L1 (sPD-L1) can reflect the expression level of PD-L1. This study aims to compare the expressional differences of sPD-L1 in serum between patients with chronic hepatitis B (CHB) and C (CHC) and further explore the factors influencing the clinical cure of CHB. Methods: 60 cases with CHB, 40 cases with CHC, and 60 healthy controls were selected. Serum levels of sPD-L1 were detected using an ELISA kit. The relationship between sPD-L1 levels and viral load, liver injury indicators, and others was analyzed in CHB and CHC patients. According to the distribution type of the data, a one-way ANOVA or Kruskal Wallis test as well as Pearson's correlation or Spearman's rank correlation analysis were performed. A difference of P<0.05 was considered statistically significant. Results: The serum sPD-L1 levels were significantly higher in CHB patients (414.6 ± 214.9) pg/ml than those in CHC patients (58.9 ± 122.1) pg/ml and the healthy control group (66.27 ± 24.43) pg/ml, and there was no statistically significant difference in serum sPD-L1 between CHC patients and the healthy control group. Further grouping and correlation analysis showed that the level of serum sPD-L1 was positively correlated with the content of HBsAg in CHB patients but not with HBV DNA, alanine transaminase, albumin, and other liver injury indicators. Additionally, there was no correlation between serum sPD-L1 levels, HCV RNA, and liver injury indicators in CHC patients. Conclusion: The serum sPD-L1 levels are significantly higher in CHB patients than those in the healthy control group and the CHC group, and there is a positive correlation between sPD-L1 levels and HBsAg. The persistent presence of HBsAg is an important mechanism for the activity of the PD-1/PD-L1 pathway, indicating that the activity of the PD-1/PD-L1 pathway may be an important factor that cannot be clinically cured in CHB as in CHC.

Abstract
The decreased capacity of auxin-, CTK-, and BR-mediated cell division and cell enlargement pathways, combined with the enhanced capacity of GA and ETH-, JA-, ABA-, SA-mediated stress-resistant pathways were presumed to be the crucial reasons for the formation of spur-type 'Red Delicious' mutants. Vallee Spur', which exhibit short internodes and compact tree shape, is the fourth generation of the spur-type bud sport mutant of 'Red Delicious'. However, the underlying molecular mechanism of these properties remains unclear. Here, comparative phenotypic, full-length transcriptome and phytohormone analyses were performed between 'Red Delicious' (NSP) and 'Vallee Spur' (SP). The new shoot internode length of NSP was ˃ 1.53-fold higher than that of the SP mutant. Cytological analysis showed that the stem cells of the SP mutant were smaller and more tightly arranged relative to the NSP. By Iso-Seq, a total of 1426 differentially expressed genes (DEGs) were detected, including 808 upregulated and 618 downregulated genes in new shoot apex with 2 leaves of the SP mutant. Gene expressions involved in auxin, cytokinin (CTK), and brassinosteroid (BR) signal transduction were mostly downregulated in the SP mutant, whereas those involved in gibberellin (GA), ethylene (ETH), jasmonate (JA), ABA, and salicylic acid (SA) signal transduction were mostly upregulated. The overall thermogram analysis of hormone levels in the shoot apex carrying two leaves detected by LC-MS/MS absolute quantification showed that the levels of IAA-Asp, IAA, iP7G, OPDA, and 6-deoxyCS were significantly upregulated in the SP mutant, while the remaining 28 hormones were significantly downregulated. It is speculated that the decreased capacity of auxin, CTK, and BR-mediated cell division and cell enlargement pathways is crucial for the formation of the SP mutant. GA and stress-resistant pathways of ETH, JA, ABA, and SA also play vital roles in stem elongation. These results highlight the involvement of phytohormones in the formation of stem elongation occurring in 'Red Delicious' spur-type bud sport mutants and provide information for exploring its biological mechanism.

Abstract
BACKGROUND Neoadjuvant therapy is recommended for locally advanced esophageal cancer, but the optimal strategy remains unclear. We aimed to evaluate the safety and efficacy of neoadjuvant chemoradiotherapy (nCRT) versus neoadjuvant chemotherapy (nCT) followed by minimally invasive esophagectomy (MIE) for locally advanced esophageal squamous cell carcinoma (ESCC). PATIENTS AND METHODS Eligible patients staged as cT3-4aN0-1M0 ESCC were randomly assigned (1 : 1) to the nCRT or nCT group stratified by age, cN stage, and centers. The chemotherapy, based on paclitaxel and cisplatin, was administered to both groups, while concurrent radiotherapy was added for the nCRT group; then MIE was carried out. The primary endpoint was 3-year overall survival. This study is registered with ClinicalTrials.gov (NCT03001596). RESULTS A total of 264 patients were eligible for the intention-to-treat analysis. By 30 November 2021, 121 deaths had occurred. The median follow-up was 43.9 months (interquartile range 36.6-49.3 months). The overall survival in the intention-to-treat population was comparable between the nCRT and nCT strategies [hazard ratio (HR) 0.82, 95% confidence interval (CI) 0.58-1.18; P = 0.28], with a 3-year survival rate of 64.1% (95% CI 56.4% to 72.9%) versus 54.9% (95% CI 47.0% to 64.2%), respectively. There were also no differences in progression-free survival (HR 0.83, 95% CI 0.59-1.16; P = 0.27) and recurrence-free survival (HR 1.07, 95% CI 0.71-1.60; P = 0.75), although the pathological complete response in the nCRT group (31/112, 27.7%) was significantly higher than that in the nCT group (3/104, 2.9%; P < 0.001). Besides, a trend of lower risk of recurrence was observed in the nCRT group (P = 0.063), while the recurrence pattern was similar (P = 0.802). CONCLUSIONS NCRT followed by MIE was not associated with significantly better overall survival than nCT among patients with cT3-4aN0-1M0 ESCC. The results underscore the pending issue of the best strategy of neoadjuvant therapy for locally advanced bulky ESCC.

Abstract
Objective: To investigate the maternal−neonatal outcomes of obstetric deliveries performed in negative pressure isolated delivery rooms (NPIDRs) during the coronavirus disease 2019 (COVID-19) omicron variant pandemic period in a single tertiary center in northern Taiwan. Methods: Confirmed positive and suspected-positive COVID-19 cases delivered in NPIDRs and COVID-19-negative mothers delivered in conventional delivery rooms (CDRs) in the period of 1 May 2022 to 31 May 2022 during the COVID-19 omicron variant pandemic stage were reviewed. The maternal−neonatal outcomes between the two groups of mothers were analyzed. All deliveries were performed following the obstetric and neonatologic protocols conforming to the epidemic prevention regulations promulgated by the Taiwan Centers for Disease Control (T-CDC). Multiple gestations, deliveries at gestational age below 34 weeks, and major fetal anomalies were excluded from this study. Results: A total of 213 obstetric deliveries were included. Forty-five deliveries were performed in NPIDRs due to a positive COVID-19 polymerase chain reaction (PCR) test (n = 41) or suspected COVID-19 positive status (n = 4). One hundred and sixty-eight deliveries with negative COVID-19 PCR tests were performed in CDRs. There was no statistical difference in maternal characteristics between the two groups of pregnant women. All COVID-19-confirmed cases either presented with mild upper-airway symptoms (78%) or were asymptomatic (22%); none of these cases developed severe acute respiratory syndrome. The total rate of cesarean section was not statistically different between obstetric deliveries in NPIDRs and in CDRs (38.1% vs. 40.0%, p = 0.82, respectively). Regardless of delivery modes, poorer short-term perinatal outcomes were observed in obstetric deliveries in NPIDRs: there were significant higher rates of neonatal respiratory distress (37.8% vs. 10.7%, p < 0.001, respectively), meconium-stained amniotic fluid (22.2% vs. 4.2%, p < 0.001, respectively) and newborn intensive care unit admission (55.6% vs. 8.3%, p < 0.001, respectively) in obstetric deliveries performed in NPIDRs than in CDRs. Maternal surgical outcomes were not significantly different between the two groups of patients. There was no vertical transmission or nosocomial infection observed in COVID-19 confirmed cases in this study period. Conclusions: Our study demonstrates that obstetric deliveries for positive and suspected COVID-19 omicron-variant cases performed in NPIDRs are associated with poorer short-term perinatal outcomes. Reasonable use of personal protective equipment in NPIDRs could effectively prevent nosocomial infection during obstetric deliveries for pregnant women infected with the COVID-19 omicron variant.

Abstract
Background Rapid and accurate detection of SARS-CoV-2 infection is the cornerstone of prompt patient care. However, the reliability of the antigen rapid diagnostic test (Ag-RDT) in the diagnosis of SARS-CoV-2 infection remains inconclusive. Methods We conducted a field evaluation of Ag-RDT performance during the Shanghai Coronavirus disease 2019 (COVID-19) quarantine and screened 7225 individuals visiting our Emergency Department. 83 asymptomatic SARS-CoV-2 (+) individuals were enrolled in the current study. Simultaneously, Ag-RDT was performed to evaluate its testing performance. Results For the Ag-RDT(−) cases, the average cycle threshold (Ct) values of the N gene were 27.26 ± 4.59, which were significantly higher than the Ct value (21.9 ± 4.73) of the Ag-RDT(+) individuals (p < 0.0001). The overall sensitivity of Ag-RDT versus that of RT-PCR was 43.37%. The Ag-RDT(+) individuals regarding the N gene’s Ct value were 16 cases in the < 20 range, 12 in 20–25, 5 in 25–30, and 3 in 30–35. The corresponding sensitivity was 84.21%, 52.17%, 21.74% and 16.67%, respectively. Meanwhile, sampling had a straight specificity of 100% regardless of the Ct value. Conclusions The Ag-RDT were extremely sensitive in asymptomatic COVID-19 individuals with a Ct value < 20.

Abstract
Background Right ventricular outflow tract obstruction (RVOTO) is the most frequently encountered congenital heart disease in patients with twin –twin transfusion syndrome (TTTS) and is especially prevalent in the recipient twin. In this retrospective study, we evaluated the incidence, prognosis, postnatal management, and perinatal outcomes of and risk factors for RVOTO in the recipient twin in severe TTTS cases which diagnosed before 26 weeks after fetoscopic laser photocoagulation (FLP) at a single center in Taiwan. Methods RVOTO was diagnosed using fetal or postnatal echocardiography. The fetal outcomes evaluated were perinatal survival rate, neonatal brain image anomalies rate, gestational age at delivery, and birth weight. Results Total 187 severe TTTS cases were included; 14 (7.49%) had a recipient twin with RVOTO (12 cases of pulmonary stenosis and 2 of pulmonary atresia). Of these 14 cases, 3 (21.4%) demonstrated improvements in outflow obstruction after FLP, and 11 (78.6%) resulted in perinatal survival. Of the 11 survivors, 5 (45.5%) received transcatheter balloon valvuloplasty to alleviate the RVOTO. The perinatal survival rate, gestational age at delivery, neonatal brain image anomaly rate, and birth weights did not significantly differ between the groups in which the recipient twin had versus did not have RVOTO. Generally, the recipient twin had RVOTO received FLP at a younger gestational age (in weeks; 19.3 ± 2.4 vs. 20.7 ± 2.6, p = 0.048) and had a higher percentage of cases at Quintero stage IV (50.0% vs. 12.1%, p < 0.001) than those in which the recipient twin did not have with RVOTO. Using logistic regression, we discovered that FLP at a younger gestational age (p = 0.046, odds ratio = 0.779) and TTTS at Quintero stage IV (p = 0.001, odds ratio = 7.206) were risk factors for the recipient twin developing RVOTO after FLP in severe TTTS cases. Conclusions The post-FLP perinatal outcomes of cases of severe TTTS in which the recipient twin had versus did not have RVOTO were comparable in this study, which may have been due to the similar gestational ages at delivery and strong influence of high Quintero stages (stages III and IV).

Abstract
Poor postharvest handling, microbial infestation, and high respiration rate are some the factors are responsible for poor storage life of perishable commodities. Therefore, effective preservation of these commodities is needed to lower the damages and extend shelf life. Preservation is regarded as the action taken to maintain desired properties of a perishable commodity as long as possible. Persimmon (Diospyros kaki) is perishable fruit with high nutritive value; however, has very short shelf-life. Therefore, effective preservation and drying is needed to extend its storage life. Drying temperature and preservatives significantly influence the quality of perishable vegetables and fruits during drying. The current study investigated the effect of different temperatures and preservatives on drying kinetics and organoleptic quality attributes of persimmon. Persimmon fruits were treated with preservatives (25% honey, 25% aloe vera, 2% sodium benzoate, 1% potassium metabisulfite, and 2% citric acid solutions) under different drying temperatures (40, 45, and 50°C). All observed parameters were significantly affected by individual effects of temperatures and preservatives, except ash contents. Similarly, interactive effects were significant for all parameters except total soluble sugars, ash contents, and vitamin C. Generally, fruits treated with citric acid and dried under 50°C had 8.2% moisture loss hour-1, 14.9 drying hours, 0.030 g H2O g-1 hr-1, 1.23° Brix of total soluble solids, 6.71 pH, 1.35% acidity, and 6.3 mg vitamin C. These values were better than the rest of the preservatives and drying temperatures used in the study. Therefore, treating fruits with citric acid and drying at 50°C was found a promising technique to extend storage life of persimmon fruits. It is recommended that persimmon fruits dried at 50°C and preserved in citric acid can be used for longer storage period.

Abstract
Many parents with a disabled child caused by a genetic condition appreciate the option of prenatal genetic diagnosis to understand the chance of recurrence in a future pregnancy. Genome-wide tests, such as chromosomal microarray analysis and whole-exome sequencing, have been increasingly used for prenatal diagnosis, but prenatal counseling can be challenging due to the complexity of genomic data. This situation is further complicated by incidental findings of additional genetic variations in subsequent pregnancies. Here, we report the prenatal identification of a baby with a MECP2 missense variant and 15q11.2 microduplication in a family that has had a child with developmental and epileptic encephalopathy caused by a de novo KCNQ2 variant. An extended segregation analysis including extended relatives, in addition to the parents, was carried out to provide further information for genetic counseling. This case illustrates the challenges of prenatal counseling and highlights the need to understand the clinical and ethical implications of genome-wide tests.

Abstract
Objective: To explore the clinical effect of microwave ablation in the treatment of early small liver cancer (≤3 cm). Methods: 103 cases with small liver cancer (tumor number < 3 and maximum tumor diameter < 3 cm) who underwent microwave ablation from November 2016 to November 2018 were retrospectively collected. The rate of residual lesions, recurrence rate one-year after the operation, and surgical complications were observed and grouped according to tumor size (< 2 cm and≥2 cm group) and tumor numbers (solitary and 2 ~ 3 lesion groups). The therapeutic effects of each group were compared and analyzed. Results: The tumor residual rate and one-year recurrence rate of small liver cancer after microwave ablation were 11.7% and 35.0%, respectively. The post-ablation syndrome incidence rate was 52.4%, with no serious adverse events. Compared with tumors < 2 cm, patients with≥2 cm had a higher postoperative residual rate (χ(2) = 7.651, P = 0.006), and the one-year recurrence rate of more solitary nodular tumors was lower (χ(2) = 10.125, P = 0.001). Conclusion: Microwave ablation is a safe and effective treatment for early small liver cancer, and it is more effective for small solitary nodules (< 2 cm).

Abstract
Pre-B-cell leukemia transcription factor 3 (PBX3) is a member of the PBX family and contains a highly conserved homologous domain. PBX3 is involved in the progression of gastric cancer, colorectal cancer, and prostate cancer; however, the detailed mechanism by which it promotes tumor growth remains to be elucidated. Here, we found that PBX3 silencing induces the expression of the cell cycle regulator p21, leading to an increase in colorectal cancer (CRC) cell apoptosis as well as suppression of proliferation and colony formation. Furthermore, we found that PBX3 is highly expressed in clinical CRC patients, in whom p21 expression is aberrantly low. We found that the regulation of p21 transcription by PBX3 occurs through the upstream regulator of p21, the tumor suppressor p53, as PBX3 binds to the p53 promoter and suppresses its transcriptional activity. Finally, we revealed that PBX3 regulates tumor growth through regulation of the p53/p21 axis. Taken together, our results not only describe a novel mechanism regarding PBX3-mediated regulation of tumor growth but also provide new insights into the regulatory mechanism of the tumor suppressor p53.

MYB_SH[AL]QKY[RF] transcription factors MdLUX and MdPCL-like promote anthocyanin accumulation through DNA hypomethylation and MdF3H activation in apple. Tree Physiol 2021; 41:836-848.

Abstract
Heritable DNA methylation is a highly conserved epigenetic mark that is important for many biological processes. In a previous transcriptomic study on the fruit skin pigmentation of apple (Malus domestica Borkh.) cv. 'Red Delicious' (G0) and its four continuous-generation bud sport mutants including 'Starking Red' (G1), 'Starkrimson' (G2), 'Campbell Redchief' (G3) and 'Vallee spur' (G4), we identified MYB transcription factors (TFs) MdLUX and MdPCL-like involved in regulating anthocyanin synthesis. However, how these TFs ultimately determine the fruit skin color traits remains elusive. Here, bioinformatics analysis revealed that MdLUX and MdPCL-like contained a well-conserved motif SH[AL]QKY[RF] in their C-terminal region and were located in the nucleus of onion epidermal cells. Overexpression of MdLUX and MdPCL-like in 'Golden Delicious' fruits, 'Gala' calli and Arabidopsis thaliana promoted the accumulation of anthocyanin, whereas MdLUX and MdPCL-like suppression inhibited anthocyanin accumulation in 'Red Fuji' apple fruit skin. Yeast one-hybrid assays revealed that MdLUX and MdPCL-like may bind to the promoter region of the anthocyanin biosynthesis gene MdF3H. Dual-luciferase assays indicated that MdLUX and MdPCL-like activated MdF3H. The whole-genome DNA methylation study revealed that the methylation levels of the mCG context at the upstream (i.e., promoter region) of MdLUX and MdPCL-like were inversely correlated with their mRNA levels and anthocyanin accumulation. Hence, the data suggest that MYB_SH[AL]QKY[RF] TFs MdLUX and MdPCL-like promote anthocyanin biosynthesis in apple fruit skins through the DNA hypomethylation of their promoter regions and the activation of the structural flavonoid gene MdF3H.

Abstract
OBJECTIVE To evaluate the association between intrauterine growth restriction (IUGR) and the incidence of fetuses with patent ductus arteriosus (PDA) and Hemodynamically significant PDA (Hs-PDA) in dichorionic twins (DC) with selective IUGR. MATERIALS AND METHODS This is an observational cohort study and retrospective case assessment, involved twins born at Linkou Chang Gung Memorial Hospital, Taoyuan, Taiwan between 2013 and 2018. DC twins with selective IUGR (sIUGR) were defined as the presence of a birth weight discordance of >25% and a smaller twin with a birth weight below the tenth percentile. PDA was diagnosed using echocardiography between postnatal day 3 and 7. Hs-PDA was defined as PDA plus increased pulmonary circulation, poor systemic perfusion, cardiomegaly, pulmonary edema, or hypotension requiring pharmacotherapeutic intervention. RESULT A total of 1187 twins were delivered during the study period, and 53 DC twins with selective IUGR were included in this study. DC twins with PDA have higher rate of preterm birth, lower gestational age of delivery, and lower mean birth weight of both twins compared with DC twins without PDA. In a comparison of the sIUGR twin with the appropriate for gestational age co-twin, both the incidences of PDA (28.30% vs. 7.55%, respectively; P = 0.003) and Hs-PDA (24.53% vs. 5.66%, respectively; P = 0.002) were higher in sIUGR fetuses than in the appropriate for gestational age co-twins. Small gestational age of delivery was the only variable to predict PDA and Hs-PDA [p = 0.002, Odds ratio = 0.57 (0.39-0.82), p = 0.009, Odds ratio = 0.71 (0.55-0.92), respectively]. CONCLUSION An analysis of dichorionic twins with sIUGR indicated that IUGR increased the risk of PDA and hemodynamically significant PDA.

Abstract
BACKGROUND The study aims to investigate the performance of a metagenomic next-generation sequencing (NGS)-based diagnostic technique for the identification of potential bacterial and viral infections and effects of concomitant viral infection on the survival rate of intensive care unit (ICU) sepsis patients. METHODS A total of 74 ICU patients with sepsis who were admitted to our institution from February 1, 2018 to June 30, 2019 were enrolled. Separate blood samples were collected from patients for blood cultures and metagenomic NGS when the patients' body temperature was higher than 38 °C. Patients' demographic data, including gender, age, ICU duration, ICU scores, and laboratory results, were recorded. The correlations between pathogen types and sepsis severity and survival rate were evaluated. RESULTS NGS produced higher positive results (105 of 118; 88.98%) than blood cultures (18 of 118; 15.25%) over the whole study period. Concomitant viral infection correlated closely with sepsis severity and had the negative effect on the survival of patients with sepsis. However, correlation analysis indicated that the bacterial variety did not correlate with the severity of sepsis. CONCLUSIONS Concurrent viral load correlates closely with the severity of sepsis and the survival rate of the ICU sepsis patients. This suggests that prophylactic administration of antiviral drugs combined with antibiotics may be beneficial to ICU sepsis patients.

Abstract
Ionizing irradiation kills pathogens by destroying nucleic acids without protein structure destruction. However, how pathogens respond to irradiation stress has not yet been fully elucidated. Here, we observed that Pseudomonas aeruginosa PAO1 could release nucleic acids into the extracellular environment under X-ray irradiation. Using scanning electron microscopy (SEM) and transmission electron microscopy (TEM), X-ray irradiation was observed to induce outer membrane vesicle (OMV) formation in P. aeruginosa PAO1. The size distribution of the OMVs of the irradiated PAO1 was similar to that of the OMVs of the non-irradiated PAO1 according to nanoparticle tracking analysis (NTA). The pyocin-related proteins are involved in OMV production in P. aeruginosa PAO1 under X-ray irradiation conditions, and that this is regulated by the key SOS gene recA. The OMV production was significantly impaired in the irradiated PAO1 Δlys mutant, suggesting that Lys endolysin is associated with OMV production in P. aeruginosa PAO1 upon irradiation stress. Meanwhile, no significant difference in OMV production was observed between PAO1 lacking the pqsR, lasR, or rhlR genes and the parent strain, demonstrating that the irradiation-induced OMV biosynthesis of P. aeruginosa was independent of the Pseudomonas quinolone signal (PQS).

Abstract
OBJECTIVE To examine the factors affecting pregnant women's decisions to accept or decline the prenatal pertussis (Tdap) vaccination in Taiwan. MATERIALS AND METHODS We conducted a cross-sectional survey, recruiting pregnant women who had received prenatal care from eight maternity hospitals between January and December 2018. We examined the participants' demographic characteristics, perceptions of pertussis disease risk and vaccination effectiveness, beliefs regarding vaccine information, physician recommendation, and other potential factors affecting decision-making regarding prenatal vaccination. RESULTS The complete survey response rate among eligible women was 78%. Among the participants, 74% accepted and 26% declined prenatal Tdap vaccination. Most women accepted Tdap during pregnancy because of perceived severity of pertussis in their infants, perceived effectiveness of the prenatal Tdap in preventing neonatal pertussis, and perceived safety of the prenatal Tdap vaccine for the fetus, as well as a provider's recommendation, which was the factor strongly associated with actual Tdap reception. Most of the participants who accepted Tdap vaccination during pregnancy and who believed that the Tdap vaccine could protect their infants from pertussis reported the receiving sufficient information to make an informed decision and trust in the information. By contrast, a large proportion of the participants who declined Tdap and who did not want to experience possible fetal side effects of Tdap reported not getting sufficient information to make an informed decision and a lack of trust in the information. CONCLUSION Developing a comprehensive strategy involving government policy, the health care system, public media, health professionals, and pregnant women to launch a successful campaign may improve the nationwide acceptance of the prenatal pertussis vaccination.

Abstract
1. Probiotic fermented feed (PFF) has been widely used in poultry production. The current study was designed to investigate whether PPF could alleviate the negative effects of hypoxia on yellow-feathered broilers reared at high altitude on the Tibet Plateau. 2. A total of 480, one-day-old male Lingnan yellow-feathered broilers were divided into four treatment groups with six replicates, each containing 20 broiler chickens. Broilers in the four groups were offered either a basal diet (without antibiotics) or test diets containing 5, 10 and 15% of PFF respectively. The experiment lasted for eight weeks. 3. Birds fed the 10% PFF diet exhibited increased (P < 0.05) average daily gain (ADG) on d 28 and 56, body weight (BW) on d 56, total tract apparent digestibility (TTAD) of dry matter (DM), crude protein (CP) and gross energy (GE). Feeding diets supplemented with 10% PFF increased (P < 0.05) digestive activity and gut development in duodenum and jejunum. Supplementation with 10% or 15% PFF significantly increased (P < 0.05) the caecal populations of Lactobacilli and Bifidobacteria spp. and decreased (P < 0.05) caecal E. coli and Salmonella spp. on d 28 and 56. 4. The ADG and BW on d 56, protease activity in duodenum on d 56 and jejunum on d 28 and 56, villus height and villi absorptive area in duodenum and jejunum and caecal Bifidobacteria spp. showed a quadratic (P < 0.05) dose response as supplemental PFF level increased. The TTAD of DM and CP and caecal Lactobacilli spp. increased linearly with PFF level. The caecal populations of E. coli and Salmonella spp. decreased linearly with PFF level. 5. In conclusion, addition of PFF in broiler diets had the potential to improve production performance, nutrient utilisation, intestinal digestive function and caecal microflora in yellow broiler chickens raised at high altitude.

Abstract
Beta-glucosidase (GBA), also known as acid β-glucosidase, exhibits an activity of glucosylceramidase (EC 3.2.1.45). Three main isoforms of β-glucosidases have been identified in mammals: GBA1, GBA2, and GBA3. The deficiency of these enzymes leads to glucosylceramide accumulation, resulting in Gaucher's disease. The present study is focused on the cytosolic β-glucosidase, GBA3, and its relationship with hepatocellular carcinoma (HCC). The expression of GBA3 mRNA in HCC was evaluated first using the TCGA database, and then by immunohistochemistry using tissue microarrays of 328 clinically characterized HCC samples and 151 non-tumor liver controls. Moreover, the presence of a correlation between GBA3 expression and clinicopathological characteristics of patients was examined. The obtained results indicated that the expression of GBA3 mRNA was significantly lower in HCC than in the adjacent non-tumor liver tissues. The expression of GBA3 was inversely related to the number of tumors (p=0.041), tumor size (p<0.001), Edmondson grade (p=0.007), microvascular invasion (p=0.049), patient status (p<0.001), and α-fetoprotein level (p<0.001). Patients exhibiting low GBA3 expression had a shorter survival time than those with high expression (p<0.001). In conclusion, the decreased GBA3 expression is strongly associated with a poor prognosis in HCC patients, and GBA3 may be a potential therapeutic target for HCC.

Abstract
DNA methylation of anthocyanin biosynthesis-related genes and MYB/bHLH transcription factors was associated with apple fruit skin color revealed by whole-genome bisulfite sequencing. DNA methylation is a common feature of epigenetic regulation and is associated with various biological processes. Anthocyanins are among the secondary metabolites that contribute to fruit colour, which is a key appearance and nutrition quality attribute of apple fruit. Although few studies reported that DNA methylation in the promoter of MYB transcription factor was associated with fruit skin color, there is a general lack of understanding of the dynamics of global and genic DNA methylation in apple fruit. Here, whole-genome bisulfite sequencing was carried out in fruit skin of apple (Malus domestica Borkh.) cv. 'Red Delicious' (G0) and its four-generation bud sport mutants, including 'Starking Red' (G1), 'Starkrimson' (G2), 'Campbell Redchief' (G3) and 'Vallee spur' (G4) at color break stage. Correlation and linear-regression analysis between DNA methylation level and anthocyanin content, as well as the transcription levels of genes related to anthocyanin biosynthesis were carried out. The results showed that the number of differentially methylated regions (DMRs) and differentially methylated genes (DMGs) was considerably increased from G1 to G4 versus the number observed in G0. The mCHH context was dominant in apple, but the levels of mCG and mCHG of DMGs were significantly higher than that of the mCHH. Genetic variation of bud sport mutants from 'Red Delicious' was associated with differential DNA methylation. Additionally, hypomethylation of mCG and mCHG contexts in flavonoid biosynthesis pathway genes (PAL, 4CL, CYP98A, PER, CCoAOMT, CHS, and F3'H), mCHG context in MYB10 at upstream, led to transcriptional activation and was conductive to anthocyanin accumulation. However, hypermethylation of mCG context in bHLH74 at upstream led to transcriptional inhibition, inhibiting anthocyanin accumulation.

Abstract
Objective: To investigate the health of gypsum miners in Hubei province and analyze the health effects of occupational disease hazards exposure on gypsum miners. Methods: In April 2017, occupational disease hazard factors were tested on the site of a gypsum mine, and 500 workers were selected by random sampling to conduct questionnaires, relevant data such as occupational health examination was collected, and descriptive statistical analysis was performed. Results: The main occupational hazards of gypsum miners were gypsum dust and noise. The time-weighted average concentration of 8 h in the workplace was 4.32 to 9.34 mg/m(3), and the post pass rate was 69.2% (9/13) ; Respiratory dust 0.13-5.15 mg/m(3), post pass rate 75.0% (3/4). Gypsum miners had finger dysfunction and muscle numbness, joint pain (29.2%, 88/301) and chest pain and breathing difficulties (17.6%, 53/301). Followed by tinnitus, auricle pus, running water (4.7%, 14/301), abnormal muscle tension (2.7%, 8/301). The exposure of occupational disease hazards was associated with respiratory, auditory and neurological symptoms of gypsum miners. Conclusion: The long-term exposure of gypsum workers to gypsum dust, noise and other harmful factors may result in obvious symptoms of respiratory system and other health damage.

Abstract
Background To evaluate the incidence and outcomes of septostomy in twin-to-twin transfusion syndrome (TTTS) after fetoscopic laser therapy. Methods A retrospective analysis of TTTS postlaser septostomy between 2005 and 2018 was performed. Postlaser septostomy was diagnosed using both (1) a free-floating intertwin membrane flap visible on ultrasound examination and (2) the rapid equalization of amniotic fluid maximum vertical pocket in the donor and recipient amniotic sacs observed after laser therapy. Perinatal survival, neonatal brain image anomaly, gestational age at operation and birth, incidence of premature rupture of membranes (PROM) within 3 weeks after operation, pseudoamniotic band syndrome, and cord entanglement were evaluated. Results In the 159 TTTS cases included, 12 had postlaser septostomy. Relative to the group without septostomy, the septostomy group had a lower total fetal survival rate (54.2% vs 73.6%, p = 0.041), an earlier mean gestational age at delivery (27.8 vs 34.4 weeks, p = 0.009), a higher risk of PROMs within 3 weeks after operation (33.3% vs 5.4%, p = 0.004), a higher cord entanglement rate (16.7% vs 0%, p = 0.005), and a higher brain image anomaly rate (23.0% [3/13] vs 5.0% [11/218], p = 0.035). After considering the severe Quintero stages (stage III and IV), postlaser septostomy was the only variable [p = 0.003, odds ratio = 5.1] to predict neonatal brain image anomaly. Postlaser septostomy combined with severe Quintero stages could predict PROMs within 3 weeks after laser therapy [p = 0.001, odds ratio = 14.1 and p = 0.03, odds ratio = 5.4, respectively] and delivery before the gestational age of 28 weeks [p = 0.017, odds ratio = 4.5 and p = 0.034, odds ratio = 2.3, respectively]. The risk of pseudoamniotic band syndrome was not increased by postlaser septostomy in this case series. Conclusions Postlaser septostomy in TTTS was associated with poorer fetal survival and more adverse perinatal outcomes even after considering severe Quintero stages before laser therapy. Efforts should be made to prevent septostomy during laser therapy, and septostomy as the primary method to treat TTTS is not advisable.

Abstract
Objective: To evaluate the diagnostic value of the heparin-binding protein (HBP), procalcitonin (PCT) and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score in ventilator-associated pneμmonia (VAP). Methods: A total of 160 patients who required tracheotomy or intubation and assisted breathing with invasive mechanical ventilator from the First Affiliated Hospital of Zhengzhou University from January 2015 to January 2017 was included in this prospective study,and divided into VAP group and no-VAP group based on if VAP happened or not; the VAP group was further divided into deterioration group and improvement group based on the curative effect after anti-infective treatment for 1 week. A total of 40 community acquired pneumonia (CAP) patients and 30 healthy volunteers were also included as control groups. The levels of HBP and PCT in blood of the subjects were tested with enzyme-linked immuno sorbent assay (ELISA) and chemiluminescence immunoassay (ECLIA) respectively, APACHE Ⅱ score was utilized to assess the severity of illness. The difference of HBP, PCT levels and APACHE Ⅱ score among the groups were analyzed. Receiver operating characteristic(ROC) curve was utilized to analyze the diagnostic value of HBP, PCT, APACHE Ⅱ score in VAP. Results: A total of 230 subjects participated in this study, including 68 VAP patients, 92 non-VAP patients, 40 CAP patients and 30 healthy volunteers. Before administration of mechanical ventilation, there were no statistically significant differences in HBP, PCT and APACHE Ⅱ score between VAP group and non-VAP group (all P>0.05). The levels of HBP,PCT and APACHE Ⅱ score were (41.4±21.3) μg/L,(0.355±0.254) μg/L,(13.4±2.5) respectively when the VAP was diagnosed,which were higher than those within the first 12 h of mechanical ventilation (7.3±2.7) μg/L, (0.080±0.038) μg/L, (8.4±2.0), all P<0.001). The HBP, PCT and APACHE Ⅱ score had no significant difference between within the first 12 h of mechanical ventilation and after mechanical ventilation in non-VAP group (all P>0.05). The levels of HBP was positively correlated with PCT and APACHE Ⅱ score (r=0.82, 0.68, all P<0.001). In deterioration group,the HBP,PCT and APACHE Ⅱ score after 1 week of anti-infective treatment were higher than those when the VAP was diagnosed (all P<0.001). No matter it is when the VAP was diagnosed or after anti-infective treatment for 1 week,the levels of HBP, PCT and APACHE Ⅱ score in deterioration group were higher than those in the improvement group (all P<0.001). The area under curve (AUC) of HBP+APACHE Ⅱ score, PCT+APACHE Ⅱ score for VAP diagnosis was 0.98, 0.95 respectively. The sensitivity of HBP+APACHE Ⅱ score in the diagnosis of VAP was lower than PCT+APACHE Ⅱ score (94.1% vs 95.6%),and the specificity was higher (92.4% vs 82.6%). Conclusion: The diagnostic value of HBP+APACHE Ⅱ score for early VAP is superior to PCT+APACHE Ⅱ score.

Abstract
Metadherin (MTDH) is a protein that is also named astrocyte elevated gene-1, and is highly expressed in a number of different tumor tissues. Although the expression of MTDH is associated with tumor invasion and recurrence, the expression of this protein in perihilar cholangiocarcinoma (PCCA) and its clinical use have not yet been investigated. In the present study, the expression of MTDH in patients with PCCA was investigated in order to determine its clinicopathological use. An immunohistochemical method was used to detect MTDH expression and the epithelial-mesenchymal transition markers E-cadherin and vimentin in 66 cases of PCCA. In addition to the expression of MTDH, the clinical and pathological data and the postoperative outcomes were analyzed. The MTDH positive expression rate was 48.5% (32/66) in PCCA. A significantly higher MTDH expression level was identified in the poor tumor differentiation group compared with the well differentiation group (P=0.007). In the positive lymph node metastasis group, a significantly higher MTDH expression level was revealed compared with the negative lymph node metastasis group (P=0.023). No association was noted with regard to the expression of MTDH and the variables age, sex, tumor diameter, tumor grade and tumor classification stage. Positive MTDH expression was significantly associated with high vimentin expression (P=0.037) compared with negative vimentin expression and inversely associated with positive E-cadherin expression compared with negative E-cadherin expression (P=0.030). Survival analysis suggested that the high MTDH expression group was associated with a worse overall survival (OS) rate and recurrence free survival (RFS) rate compared with the low MTDH expression group (P<0.001 and P=0.01, respectively). Cox regression analysis indicated that the Tumor-Node-Metastasis, surgery margin and high MTDH expression were independent OS and RFS factors for PCCA. MTDH expression may serve an important function in PCCA tumor growth and metastasis. Targeting MTDH may have important therapeutic applications for patients with PCCA.

Abstract
Anthocyanin is an important parameter for evaluating the quality of wine grapes. However, the effects of different light intensities on anthocyanin synthesis in grape berry skin and its regulation mechanisms are still unclear. In this experiment, clusters of wine grape cv. ‘Marselan’ were bagged using fruit bags with different light transmittance of 50%, 15%, 5%, and 0, designated as treatment A, B, C and D, respectively. Fruits that were not bagged were used as the control, designated as CK. The anthocyanin composition and concentration, as well as gene expression profiles in the berry skin were determined. The results showed that the degree of coloration of the berry skin reduced with the decrease of the light transmittance, and the veraison was postponed for 10 days in D when compared with the CK. Total anthocyanin concentration in the berry skin treated with D decreased by 51.50% compared with CK at the harvest stage. A total of 24 and 21 anthocyanins were detected in CK and D, respectively. Among them, Malvidin-3-O-coumaroylglucoside (trans), which showed a significant positive correlation with the total concentration of anthocyanins at the harvest stage (r = 0.775) and was not detected in D, was presumed to be light-induced anthocyanin. Other anthocyanins which were both synthesized in CK and D were considered to be light-independent anthocyanins. Among them, Malvidin-3-O-coumaroylglucoside (cis) and Malvidin-3-O-acetylglucoside were typical representatives. Remarkably, the synthesis of light-inducible anthocyanins and light-independent anthocyanins were regulated by different candidate structural genes involved in flavonoid biosynthesis pathway and members of MYB and bHLH transcription factors.

Abstract
BACKGROUND Plant photosynthesis can be improved by elevated CO2 concentration (eCO2). In vitro growth under CO2 enriched environment can lead to greater biomass accumulation than the conventional in micropropagation. However, little is know about how eCO2 promotes transformation of grape plantlets in vitro from heterotrophic to autotrophic. In addition, how photosynthesis-related genes and their proteins are expressed under eCO2 and the mechanisms of how eCO2 regulates RbcS, Rca and their proteins have not been reported. RESULTS Grape (Vitis vinifera L. cv. 'Pinot Noir') plantlets in vitro were cultured with 2% sucrose designated as control (CK), with eCO2 (1000 μmol·mol- 1) as C0, with both 2% sucrose and eCO2 as Cs. Here, transcriptomic and proteomic profiles associated with photosynthesis and growth in leaves of V. vinifera at different CO2 concentration were analyzed. A total of 1814 genes (465 up-regulated and 1349 down-regulated) and 172 proteins (80 up-regulated and 97 down-regulated) were significantly differentially expressed in eCO2 compared to CK. Photosynthesis-antenna, photosynthesis and metabolism pathways were enriched based on GO and KEGG. Simultaneously, 9, 6 and 48 proteins were involved in the three pathways, respectively. The leaf area, plantlet height, qP, ΦPSII and ETR increased under eCO2, whereas Fv/Fm and NPQ decreased. Changes of these physiological indexes are related to the function of DEPs. After combined analysis of proteomic and transcriptomic, the results make clear that eCO2 have different effects on gene transcription and translation. RbcS was not correlated with its mRNA level, suggesting that the change in the amount of RbcS is regulated at their transcript levels by eCO2. However, Rca was negatively correlated with its mRNA level, it is suggested that the change in the amount of its corresponding protein is regulated at their translation levels by eCO2. CONCLUSIONS Transcriptomic, proteomic and physiological analysis were used to evaluate eCO2 effects on photosynthesis. The eCO2 triggered the RbcS and Rca up-regulated, thus promoting photosynthesis and then advancing transformation of grape plantlets from heterotrophic to autotrophic. This research will helpful to understand the influence of eCO2 on plant growth and promote reveal the mechanism of plant transformation from heterotrophic to autotrophic.

Abstract
Autophagy is a genetically well-controlled cellular process that is tightly controlled by a set of core genes, including the family of autophagy-related genes (ATG). Autophagy is a “double-edged sword” in tumors. It can promote or suppress tumor development, which depends on the cell and tissue types and the stages of tumor. At present, tumor immunotherapy is a promising treatment strategy against tumors. Recent studies have shown that autophagy significantly controls immune responses by modulating the functions of immune cells and the production of cytokines. Conversely, some cytokines and immune cells have a great effect on the function of autophagy. Therapies aiming at autophagy to enhance the immune responses and anti-tumor effects of immunotherapy have become the prospective strategy, with enhanced antigen presentation and higher sensitivity to CTLs. However, the induction of autophagy may also benefit tumor cells escape from immune surveillance and result in intrinsic resistance against anti-tumor immunotherapy. Increasing studies have proven the optimal use of either ATG inducers or inhibitors can restrain tumor growth and progression by enhancing anti-tumor immune responses and overcoming the anti-tumor immune resistance in combination with several immunotherapeutic strategies, indicating that induction or inhibition of autophagy might show us a prospective therapeutic strategy when combined with immunotherapy. In this article, the possible mechanisms of autophagy regulating immune system, and the potential applications of autophagy in tumor immunotherapy will be discussed.

Abstract
BACKGROUND Bud sport mutants of apple (Malus domestica Borkh.) trees with a highly blushed colouring pattern are mainly caused by the accumulation of anthocyanins in the fruit skin. Hormones are important factors modulating anthocyanin accumulation. However, a good understanding of the interplay between hormones and anthocyanin synthesis in apples, especially in mutants at the molecular level, remains elusive. Here, physiological and comparative transcriptome approaches were used to reveal the molecular basis of color pigmentation in the skin of 'Red Delicious' (G0) and its mutants, including 'Starking Red' (G1), 'Starkrimson' (G2), 'Campbell Redchief' (G3) and 'Vallee spur' (G4). RESULTS Pigmentation in the skin gradually proliferated from G0 to G4. The anthocyanin content was higher in the mutants than in 'Red Delicious'. The activation of early phenylpropanoid biosynthesis genes, including ASP3, PAL, 4CL, PER, CHS, CYP98A and F3'H, was more responsible for anthocyanin accumulation in mutants at the color break stage. In addition, IAA and ABA had a positive regulatory effect on the synthesis of anthocyanins, while GA had the reverse effect. The down-regulation of AACT1, HMGS, HMGR, MVK, MVD2, IDI1 and FPPS2 involved in terpenoid biosynthesis influences anthocyanin accumulation by positively regulating transcripts of AUX1 and SAUR that contribute to the synthesis of IAA, GID2 to GA, PP2C and SnRK2 to ABA. Furthermore, MYB and bHLH members, which are highly correlated (r=0.882-0.980) with anthocyanin content, modulated anthocyanin accumulation by regulating the transcription of structural genes, including CHS and F3'H, involved in the flavonoid biosynthesis pathway. CONCLUSIONS The present comprehensive transcriptome analyses contribute to the understanding of the the relationship between hormones and anthocyanin synthesis as well as the molecular mechanism involved in apple skin pigmentation.

Abstract
Objective: To investigate the effects of fluoride exposure on the thyroid hormone level and intelligence in rats and to investigate the biomarkers of intellectual impairment induced by high fluoride exposure. Methods: A total of 24 clean healthy Sprague-Dawley rats were randomly divided into control group (tap water containing 0.344 mg/L fluoride) and low-, medium-, and high-fluoride exposure groups (tap waters containing 10, 50, and 100 mg/L sodium fluoride, respectively). One male rat was cohabited with two female rats in the same group. After the offspring rats were weaned, 12 offspring rats (male/female ratio=1∶1) with a similar body weight in each group were subjected to the same treatment for the parental offspring. The offspring rats were sacrificed on the 60th day after birth. The weight of offspring rats was measured. Serum thyrotropin (TSH) , free triiodothyronine (FT(3)) , and free thyroxine (FT(4)) levels were measured by enzyme-linked immunosorbent assay. The learning and memory abilities of the rats were evaluated by Morris water maze test. The expression of mitochondrial fission 1 (Fis1) and mitofusin 1 (Mfn1) in blood was measured by Western blot. Results: The offspring rats in the medium-and high-fluoride exposure groups had significantly lower serum TSH and FT(4) levels than those in the control group (P<0.05). The place navigation test showed that the offspring rats in the medium-and high-fluoride exposure groups had significantly longer escape latency than those in the control group (P<0.05) , and the high-fluoride exposure group had a significantly longer escape distance than those in the control group (P<0.05). The spatial probe test showed that the offspring rats in the low-, medium-, and high-fluoride exposure groups had significantly shorter swimming time and distance in the target quadrant and total swimming time and distance than those in the control group (P<0.05). Compared with the offspring rats in the control group, those in the low-, medium-, and high-fluoride exposure groups had significantly higher expression of Fis1 (P<0.05) , and those in the low- and medium-fluoride exposure groups had significantly higher expression of Mfn1 (P<0.05) . Conclusion: High fluoride exposure can reduce the secretion of thyroid hormone and the abnormality of mitochondrial dynamics in peripheral lymphocytes may provide a clue to identifying the biomarkers of intellectual impairment induced by fluoride exposure.

Abstract
Objective: To investigate the influence of thermal cycling on the mechanical properties of resin-ceramic composites. Methods: The different groups of resin-ceramic composites A (Lava Ultimate, 3M ESPE, USA), B (block HC, Shofu, Japan), C (Hyramic, Upcera, China), D (Vita Enamic, Vita, German), and the feldspar ceramic E (Mark Ⅱ, Vita, German) were included in this study. The properties of these groups (with 30 samples in each group), including flexural strength, flexural modulus and Vickers hardness were tested before and after thermal cycling (0, 10 000 and 20 000 cycles, respectively). The data were statistically analyzed. Results: Before thermal cycling, the flexural strength of groups A, B and C [(166.28±13.78) MPa, (170.21±11.36) MPa and (202.04±16.55) MPa] were higher than those of groups D and E [(137.09±8.83) MPa and (119.35±5.98) MPa], and the flexural modulus [(62.39±3.40) GPa] and Vickers hardness [(406.97±14.73) HV] of E group were higher than those of other groups (P<0.05). The flexural strength, flexural modulus and Vickers hardness of groups D and E did not change after thermal cycling (all P>0.05), while those of groups A, B and C decreased (all P<0.05). Conclusion: After thermal cycling, the mechanical properties of the A, B and C groups decreased, while those of the groups D and E were stable.

Abstract
Ceratovacuna lanigera Zehntner is a major leaf pest of sugarcane. Widely distributed, it affects both the yield and quality of sugarcane in China. This study aimed to assess real yield and sugar yield losses, and the effect of C. lanigera damage on emergence of newly planted and ratoon cane under current production levels. Field experiments were carried out from 2014 to 2016 in Yunnan Province China. At maturity, plants were harvested and weighed to determine yield, and the effect on sugarcane quality and sucrose content analyzed. Real yield decreased by average of 46,185 kg hm-2 (range: 37,545-61,845 kg hm-2) in damaged versus undamaged areas, with an average yield loss rate of 35.9% (28.5-45.7%). Juice yield decreased by an average of 3.01% (2.4-4.13%) and sucrose content by 6.38% (5.48-8.16%). Juice brix decreased by an average of 7.66°BX (6.95-9.05°BX) and juice gravity purity by 12.35% (8.43-19.97%). In contrast, the reducing sugar content increased by an average of 1.21% (1.01-1.3%). Emergence rates of newly planted cane decreased by an average of 26.0% (24.7-27.3%). The emergence number of ratoon cane decreased by 66,834 hm2 (57,429-76,238 hm-2) and relative emergence loss rates of ratoon cane decreased by an average of 57.8% (57.6-58.0%). These findings confirm that C. lanigera damage severely affects sugarcane yield and quality in Yunnan Province. The results will help the implementation of effective control measures, thereby supporting sustainable development of the Chinese sugar industry.

Abstract
Objective: To establish an animal model of pulmonary metastasis from nasopharyngeal carcinoma (NPC) and to investigate differential genes associated with pulmonary metastasis. Methods: CNE cell line was used to construct the stable metastasis CNE/Luc cell line which steadily expresses the fluorescent enzyme genes. The CNE/Luc cells were injected into immunodeficiency mice through tail vein, and with the in vivo imaging technology, the mice with pulmonary metastasis were filtered out. The pulmonary metastasis cells, were separated and injected into the tail vein of other nude mice to obtain the tissue-specificity metastasis cells confirmed by fluorescent imaging system. Based on the gene chip, the differential genes associated with pulmonary metastasis for NPC were found. Results: The gene expression profiles of nasopharyngeal carcinoma cell line CNE/Luc and their lung metastasis-associated subpopulation CNE/Luc-2 were constructed by gene chip technology. Ten metastasis-related genes were screened by software analysis, namely as TP53, PIK3CA, MET, KRAS, VEGFA, EDNRB, GSK3B, FOXO3, SOD2, and BIRC3. Conclusions: Some genes including TP53, PIK3CA, MET, KRAS, VEGFA, EDNRB, GSK3B, FOXO3, SOD2, and BIRC3 are indicated to have important roles in the lung metastasis of nasopharyngeal carcinoma.

Abstract
The oral administration of Enterococcus faecium EF1 to new-born suckling and weaning piglets along with their growth performances and intestinal microbiota was investigated in this study. Twenty-four new-born piglets were initially divided into 2 groups. The probiotics group received 2 ml of 10% sterilised skimmed milk by oral gavage supplemented with 6×10(8) cfu/ml viable E. faecium EF1 at the first, the third and the fifth day after birth, while the control group received 2 ml of 10% sterilised skimmed milk without probiotics at the same time. Results showed that oral administration of E. faecium EF1 was associated with a remarkable increase on the body weight of piglets for both suckling and weaning periods, by 30.73% (P<0.01) and 320.84% (P<0.01), and also decreased the diarrhoea rate, by 43.21% (P<0.05) and 71.42% (P<0.05), respectively. In addition, 454-pyrosequencing analysis revealed that there was no significant difference in the intestinal microbial diversity of the suckling piglets between the two groups; nevertheless, when compared to the control group, the relative abundance of Firmicutes in the probiotics group was substantially augmented, while the relative abundance of Proteobacteria, Bacteroidetes and Fusobacteria diminished. However, results indicated that oral administration of E. faecium EF1 did not have any influence on the relative abundance of Firmicutes in weaning piglets rather than increasing the relative abundance of Bacteroidetes and decreasing the relative abundance of Proteobacteria. Furthermore, at the level of the Firmicutes phylum, the relative abundance of Lactobacillales in the probiotic group increased significantly. These findings suggest that oral administration of E. faecium EF1 to new-born piglets could improve the growth performance and intestinal microbiota of piglets for both suckling and weaning periods.

Abstract
The aim of this research was to study the clinical significance and expression of CD4+CD25+ regulatory T cells (Tregs) and p3Forkhead transcription factor-3 (Foxp3) in peripheral blood of patients with gastric carcinoma (GC) and to investigate the effects in the occurrence and development process of GC, to further comprehend their clinical values and provide a theoretical basis for the early diagnosis and immunotherapy of GC. The expression levels of CD4+CD25+Foxp3+Tregs in GC patients, at TNM staging, differentiated degree, lymphatic metastasis, cancer sites and cancer diameter of GC, were analyzed within the groups. The comparison of the expression levels of CD4+CD25+Foxp3+Tregs in peripheral blood between the GC group and the healthy control group showed a statistically significant difference. At TNM staging within the groups, pairwise comparisons of the expression levels of CD4+CD25+Foxp3+Tregs indicated that differences among the stage I+II group, stage III group and stage IV group were statistically significant. The expression levels of CD4+CD25+Foxp3+Tregs are closely relative to the occurrence and development of GC, providing theoretical bases and evidence for the early diagnosis, prognosis evaluation and immunotherapy of GC.

Abstract
BACKGROUND Metadherin (MTDH) protein, also called astrocyte elevated gene-1 (AEG-1) is over expressed in a variety of malignant tumours, and is closely related to tumour invasion and the poor prognosis. OBJECTIVE This study tries to explore the clinical pathological significance of MTDH expression in a large cohort of patients with PTC. DESIGN AND PATIENTS Immunohistochemistry was used to detect MTDH expression in 156 cases of PTC, 6 cases of anaplastic thyroid carcinoma (ATC), 10 cases of multinodular goitre (MNG) and 10 cases of thyroid adenoma tissues who received a thyroid operation between June 2003 and July 2008. MEASUREMENTS Clinical pathological data of 156 cases of PTC were analysed according to MTDH expression. The Kaplan-Meier method was used to plot survival curves and log-rank test to compare the postoperative survival results. The prognostic meaning of MTDH expression in PTC was evaluated by Cox regression analysis. RESULTS The positive expression rates of MTDH in PTC and ATC tissues were 37·2% (58/156) and 50% (3/6), respectively, and MTDH positive expression rates were both 10% (1/10) in MNG and thyroid adenoma tissues. High MTDH expression in PTC was associated with larger tumour size (P = 0·030), high rates of lymph node (P = 0·041) and distant metastasis (P = 0·028), but no relation with the patient age, gender, tumour multicenter, extrathyroid invasion and tumour grade. High MTDH expression was associated with recurrence-free survival (RFS) and disease-specific survival rate (DSS) (P = 0·014, P = 0·001, respectively). Cox regression analysis showed that high MTDH expression was independent prognostic indicators for RFS and DSS in patients with PTC (P = 0·023 and P = 0·035, respectively). CONCLUSION High MTDH expression in PTC might play an important role in tumour growth and metastasis, and targeting MTDH treatment might have potential therapeutic value for patients with PTC.

Abstract
The activation of oncogenes and the loss of tumor suppressor genes are believed to play critical roles in the pathogenesis of human hepatocellular carcinoma (HCC). Metaherin (MTDH), also called astrocyte elevated gene-1 (AEG-1), is frequently amplified in a variety of cancers, but the roles of MTDH with regard to growth and apoptosis in HCC have not yet been studied. In the present study, we first analyzed the expression of MTDH in HCC samples. We found that MTDH protein levels are higher in most HCC cancerous tissues compared with their matched adjacent non-tumor tissues. Additionally, the MTDH mRNA was also higher in HCC tissues compared to their matched adjacent non-tumor tissues. Knockdown of the endogenous MTDH using small interfering RNA further showed that deficiency of MTDH suppressed cell growth and caused apoptosis in HCC cells. Knockdown MTDH promoted PTEN and p53 expression in HCC cells and inhibited AKT phosphorylation. Knockdown MTDH also inhibited tumor growth in vivo. All these results indicated that MTDH protein levels in most HCC tissues are higher than non-tumor tissues, and knockdown of MTDH inhibited growth and induced apoptosis in HCC cells through the activation of PTEN. Therefore, MTDH might be an effective targeted therapy gene for HCC.

Abstract
The aim of this study was to investigate the influence of ulinastatin (UTI) on high mobility group box 1 (HMGB1), tumor necrosis factor (TNF)-α, and interleukin (IL)-6 expression in acute lung injury (ALI) rats with sepsis caused by cecal ligation and puncture (CLP) surgery, as well as to examine the underlying biological mechanism. Thirty rats were randomly and evenly divided into sham (control), CLP, and CLP + UTI groups. Thirty minutes after the surgery, the rats in the CLP + UTI group received UTI via the caudal vein, while normal saline was administered to rats in the other groups. Blood, lung tissues, and bronchoalveolar lavage fluid (BALF) were collected at different time points (6, 12, 24, and 48 h) after surgery for determination of related indicators. Compared with the CLP group, rats in the CLP + UTI group exhibited higher seven day survival rates, less lung injury, and decreased HMGB1 expression in the lung tissue, serum, and BALF. In addition, the levels of TNF-α and IL-6 at 24 h in the CLP + UTI group were markedly lower than those in the CLP group. These results suggest that by deregulation, UTI might decrease the lung injury and increase the survival time of ALI rats by downregulating HMGB1 expression as well as by inhibiting TNF-α and IL-6 levels in serum and BALF.

Abstract
BACKGROUND Sepsis is a common complication of infections, burns, traumas, surgeries, poisonings, and post-cardiopulmonary resuscitation. The present study aimed to investigate prognostic value of CD4(+)CD25(+) regulatory T cells (Treg) in peripheral blood of patients with sepsis. METHODS Periphery blood from 28 patients diagnosed with sepsis was collected on day 1 and 7 after hospitalization in the ICU of Shanghai Changzheng Hospital between December 2013 to April 2014. The blood was used for analyses of Treg ratio using flow cytometry and for analyses of blood routine test, C-reactive protein (CRP), bilirubin, procalcitonin (PCT), and coagulation. APACHE II and sequential organ failure assessment (SOFA) scores were also investigated. The results were compared between two outcome groups of survival or death to evaluate prognostic value for sepsis. RESULTS The patients had an average age of 60.36±15.03 years, APACHE II score 16.68±7.00, and SOFA score 7.18±3.78. Among the 28 patients, 12 had severe trauma (42.9%), 10 had septic shock (35.7%), and 9 (32.2%) died. The median ratio of Tregs was 2.10% (0.80%, 3.10%) in the survival group vs. 1.80% (1.15%, 3.65%) in the death group (Z=-0.148, P=0.883) on day 1; however it was significantly changed to 0.90% (0.30%, 2.80%) vs. 5.70% (2.60%, 8.30%) (Z=-2.905, P=0.004). CONCLUSION With better prospects for clinical application, dynamic monitoring of Tregs ratio in peripheral blood has potential value in predicting prognosis of sepsis.

Abstract
We conducted a hospital-based case-control study to evaluate the association between polymorphisms in excision repair cross-complementing group 1-xeroderma pigmentosum group F (ERCC1-XPF) variants and the risk of colorectal cancer in a Chinese population. Genotyping of the ERCC1 rs2298881 and rs11615 and XPF rs2276466 polymorphisms were detected by polymerase chain reaction-restriction fragment length polymorphism. Colorectal cancer cases were more likely to be smokers, consume alcohol, have higher energy intake, and have a family history of cancer. Using conditional regression analysis, subjects carrying the ERCC1 rs2298881CC genotype and C allele showed a significantly increased risk of colorectal cancer compared with those carrying the AA genotype. However, we found no association between the rs11615 and rs2276466 polymorphisms and the risk of colorectal cancer. In conclusion, the ERCC1 rs2298881 polymorphism may be used as a predictive factor for determining the risk of colorectal cancer in a Chinese population. This finding may be useful for identifying the genetic characteristics of colorectal cancer and developing more efficient strategies for prevention and treatment.

Abstract
BACKGROUND Given the lack of studies, whether the addition of adjuvant chemotherapy (AC) to concurrent chemoradiotherapy (CCRT) is superior to CCRT alone for locoregionally advanced nasopharyngeal carcinoma (NPC) remains unclear. The main objective of this Bayesian network meta-analysis was to determine the efficacy of CCRT + AC when compared with CCRT alone. PATIENTS AND METHODS We systematically searched databases and extracted data from randomized, controlled trials involving NPC patients randomly assigned to receive CCRT + AC, CCRT, or radiotherapy (RT). Overall survival (OS), locoregional recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS) with hazard ratios (HRs) were investigated. A Bayesian network for different outcomes was established to incorporate all evidence. Multiple treatment comparisons based on the network integrated the efficacy of CCRT + AC, CCRT, and RT. RESULTS Eight studies involving 2144 patients were analyzed. In the network meta-analysis, CCRT + AC and CCRT were both significantly better than RT alone for all outcomes, except that no significant difference was found between CCRT and RT for LRFS. Though ranking probabilities showed that CCRT + AC was ranked superior to CCRT for OS, LRFS, and DMFS, no significant differences were found between CCRT+AC and CCRT for all outcomes [OS: HR = 0.86, 95% credible interval (CrI) 0.60-1.16; LRFS: HR = 0.72, 95% CrI 0.43-1.15; DMFS: HR = 0.86, 95% CrI 0.62-1.16]. CONCLUSIONS No significant improvement was found following CCRT + AC compared with CCRT alone. Whether the omission of additional AC can reduce toxic effects without adversely affecting survival in patients with locoregionally advanced NPC should be further explored, in addition to the precise patient status that would benefit from AC following CCRT.

Abstract
AIM: To investigate the clinical characteristics, treatment and prognosis of gastroenterology patients with shock.
METHODS: Clinical data for 105 gastroenterology patients with shock treated at our department from January 2013 to June 2014 were analyzed retrospectively.
RESULTS: The incidence of shock was 9.090% (11/121) in patients with acute pancreatitis, 8.957% (61/681) in patients with digestive tract hemorrhage, 6.081% (9/148) in patients with shock, and 3.675% (24/653) in patients with acute cholecystitis or cholangitis. There was a significant difference in the incidence of shock among the above four groups of patients (χ2 = 16.5928, P < 0.05). Of the 105 shock patients, 52 (49.52%) were referred and 12 (11.43%) died. Of 32 cases with infectious shock, 28 (87.50%) were referred and 5 (15.63%) died. Of 65 cases with shock due to severe blood loss, 18 (27.69%) were referred and 6 (9.23%) died. Of 6 cases with cardiac shock, all (100%) were referred and 1 (16.67%) died. Of two cases with anaphylactic shock, no referral or death occurred. The rates of referral and death were statistically significant among different groups (χ2 = 38.9325, P < 0.05; χ2 = 106.2876, P < 0.05).
CONCLUSION: Acute infectious, hemorrhagic disease is the most important primary disease combined with shock. Cardiogenic shock is associated with the highest mortality, followed by septic shock, hypovolemic shock and anaphylactic shock. Timely rescue is successful in the majority of cases. Strengthened care of critically ill patients, early diagnosis and treatment, and multidisciplinary collaboration can improve the rescue success rate and reduce mortality.

Abstract
This experiment was conducted to evaluate the effects of dietary inclusion of Bacillus licheniformis on laying performance, egg quality, antioxidant enzyme activities, and intestinal barrier function of laying hens. Hy-Line Variety W-36 hens (n = 540; 28 wk of age) were randomized into 6 groups, each group with 6 replications (n = 15). The control group received the basal diet formulated with maize and soybean meal. The treatment groups received the same basal diets supplemented with 0.01, 0.02, 0.03, 0.06, and 0.09% Bacillus licheniformis powder (2 × 10(10) cfu/g) for an 8-wk trial. The results showed that dietary supplementation with 0.01 and 0.03% B. licheniformis significantly increased egg production and egg mass. However, no significant differences were observed in egg weight, feed consumption, and feed conversion efficiency among the 6 groups. Supplementation with different levels of B. licheniformis was found to be effective in improvement of egg quality by increasing egg shell thickness and strength. Compared with control, d-lactate content, diamine oxidase activity, and adrenocorticotropic hormone level in serum decreased significantly, and the level of estradiol and follicle-stimulating hormone increased significantly in plasma of all the experimental groups. Dietary supplementation with B. licheniformis increased the intestinal villus height and reduced the crypt depth. In conclusion, dietary inclusion of B. licheniformis could improve laying performance and egg quality significantly in a dose-dependent manner by decreasing the stress response, upregulating the growth hormone, and improving intestinal health.
