Abstract
Some studies have demonstrated that acrylamide (AA) was correlated with oxidative stress, resulting in physical damage. The jackfruit flake was an immature pulp that contained a high level of antioxidant activity. This study aimed to assess the defensive efficacy of jackfruit flake in AA-induced oxidative stress before and after simulated gastrointestinal digestion. Our results indicate that the total polyphenol content of Jackfruit flake digest (Digestive products of jackfruit flake after gastrointestinal, JFG) was diminished; however, JFG had raised the relative antioxidant capacity compared to Jackfruit flake extract (JFE). Additionally, the results of High Performance Liquid Chromatography-Mass Spectrometry (HPLC-MS) implied that a proportion of compounds were degraded/converted into other unknown and/or undetected metabolites. Further, by high content analysis (HCA) techniques, JFG markedly reduced cytotoxicity and excessive production of reactive oxygen species (ROS) in cells, thereby alleviating mitochondrial disorders. In this study, it may be converted active compounds after digestion that had preferable protective effects against AA-induced oxidative damage.

Abstract
The cotton mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) is a polyphagous insect that attacks tens of plant and causes substantial economic loss. Insect chitinases are required to remove the old cuticle to allow for continued growth and development. Though insect chitinases have been well studied in tens of insects, their functions in mealybug are still not addressed. Here, we sequenced the transcriptomes of adult males and females, from which eight chitinase genes were identified. We then used the method of rapid amplification of cDNA ends to amplify their full length. Phylogenetic analysis indicated that these genes clustered into five subgroups. Among which, group II PsCht2 had the longest transcript and was highly expressed at second instar nymph. PsCht10, PsCht3-3 and PsIDGF were highly expressed in the adult females, whereas PsCht4 and PsCht4-1 were significantly expressed at the male pupa and adult male. Next, we knocked down all eight chitinase genes by feeding the double-stranded RNA. Knockdown of PsCht4 or PsCht4-1 led to the failure of moult and, silencing PsCht5 resulted in pupation defect, while silencing PsCht10 led to small body size, suggesting these genes have essential roles in development and can be used as a potential target for pest control.

Abstract
Objective: To investigate the predictive value of neutrophil-to-lymphocyte Ratio (NLR) in 30-day mortality of patients with acute paraquat poisoning. Methods: We respectively reviewed the clinical parameters of 115 patients with acute paraquat poisoning. They were divided into survival (n=64) and non-survival (n=51) groups based on their 30-day outcome. Multivariate logistic regression was performed to identify risk factors of 30-day mortality. Receiver operating curve (ROC) test was applied to analysis to the predictive value of NLR in 30-day mortality ofacute paraquat poisoning patients. The correlations between NLR and severity index of paraquat poisoning (SIPP) were analyzed using Spearman's rank correlation coefficient. Results: Of the 115patients included in the study, 54 (46.96%) patients were males and 61 (53.04%) were females with a mean age of 38.96±13.58 years. The total mortality in 30-day was 44.35% (51/115) . The NLR at admission was an independently risk factor of 30-day mortality of patients with acute paraquat poisoning (OR 1.477, 95%CI 1.035-2.107, P<0.05) . The NLR to predict the death of the area under the ROC curve was 0.894 (95%CI: 0.8212-0.9663, P<0.01) ; the optimal cutoff threshold was 11.71; the sensitivity was 71.79% and the specificity was 94.29%; the positive predictive value was 93.33%and negative predictive value of 75.00%. Meanwhile, the positive likelihood ratio was 12.57 and the negative likelihood ratio was 0.30. The NLR was significantly associated with SIPP (Spearman rho 0.525; P<0.01) and it was significantly higher in patients with SIPP of ten or higher than in those with an SIPP less than 10 (15.02±12.40 vs. 6.19±2.54, P<0.05) . Conclusion: The increased NLR at admission was an independently risk factor of 30-day mortality of patients with acute paraquat poisoning and it was significantly correlated with SIPP score. Therefore, NLR was useful for predicting prognosis of patients with acute paraquat poisoning.

Abstract
BACKGROUND The Proteus is one of the most common human and animal pathogens. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR/Cas) are inheritable genetic elements found in a variety of archaea and bacteria in the evolution, providing immune function against foreign invasion. OBJECTIVES To analyze the characteristics and functions of the CRISPR/Cas system in Proteus genomes, as well as the internal and external factors affecting the system. METHODS CRISPR loci were identified and divided into groups based on the repeat sequence in 96 Proteus strains by identification. Compared the RNA secondary structure and minimum free energy of CRISPR loci through bioinformatics, the evolution of cas genes, and the effects of related elements were also discussed. RESULTS 85 CRISPR loci were identified and divided into six groups based on the sequence of repeats, and the more stable the secondary structure of RNA, the smaller the minimum free energy, the fewer base mutations in the repeat, the more stable the CRISPR and the more complete the evolution of the system. In addition, Cas1 gene can be a symbol to distinguish species to some extent. Of all the influencing factors, CRISPR/Cas had the greatest impact on plasmids. CONCLUSIONS This study examined the diversity of CRISPR/Cas system in Proteus and found statistically significant positive/negative correlations between variety factors (the RNA stability, free energy, etc.) and the CRISPR locus, which played a vital role in regulating the CRISPR/Cas system.

Abstract
Urethral diverticulum is a condition where the urethra or the periurethral glands push into the connective tissue layers that surround it. Patients of urethral diverticulum present with nonspecific symptoms such as incontinence, urinary frequency and urgency, and pain during sexual intercourse and urination. The incidence of this condition is low. We report a case of giant anterior urethra stones combined with a diverticulum with no lower urinary tract symptoms. We believe that this case is extremely rare, and the process of diagnosis and treatment is of great significance in clinical practice.

Abstract
A new correlation electron cyclotron emission (CECE) diagnostic has recently been installed on the HL-2A tokamak in order to study electron temperature fluctuations. Eight radial locations are measured simultaneously through eight pairs of correlated channels. Multiplexers are employed in the intermediate frequency section instead of the conventional separated filter banks to meet strict cross-isolation specifications and lower insertion loss. Relative electron temperature fluctuations are observed by CECE for the first time on the HL-2A by using the spectral decorrelation method. The achieved minimum detectable fluctuation level is up to (T̃e/Te)min∼0.5%. When studying electron temperature fluctuations in the core region with gas puffing, the cross-power spectra show that the amplitude of the electron temperature fluctuation increases in a high temperature and low density plasma. Further analysis demonstrates that the electron temperature gradient ∇Te drives the electron temperature fluctuations together with electron heat transport.

Abstract
Objective: To investigate the clinical and laboratory features of Phytosterolemia with hematological abnormalities. Methods: A retrospective study was performed on 20 patients with phytosterolemia admitted to the hematology department of the First Affiliated Hospital of Suzhou University during 2004-2017. History of patients was collected and the platelet counts, lipidomic analysis of plasma and osmotic fragility of erythrocytes were carried out. The erythrocyte and platelet morphology was examined by light microscope. Phytosterol levels in serum were measured by high performance liquid chromatography method. All of ABCG5/8 exons and intron-exon boundaries were amplified by PCR and directly sequenced to identify mutations. Results: All patients had been misdiagnosed as immune thrombocytopenia (ITP), or Evans syndrome with a mean delay of 21 years between symptom onset and accuracy diagnosis. The clinical manifestations of the patients were variable, but most of them presented with thrombocytopenia, anemia, splenomegaly from early ages, and xanthomas. Other major features were also observed, such as impaired liver functions (9 cases), premature atherosclerosis (5 cases) and/or arthritis (4 cases). Interestingly, all patients displayed an increased osmotic fragility of red cells and unique blood film features: large unequal platelets surrounded by a circle of vacuoles and various abnormal erythrocyte shapes, especially stomatocyte. Serum levels of the sitosterol and stigmasterol in the patients were remarkably elevated up to 331.05(276.00, 670.20)mg/L and 244.60(193.78,399.40)mg/L, about 10 and 24 times higher than those of normal subjects. There were 14 mutations in ABCG5/8 genes found in the patients. Among them, 2/3 of the mutations were in ABCG5 gene, including p.(E22X), p.(R446X),g.ISV7+3G>A, p.(R446X), p.(R419H), g.ISV7+3G>A, p.(G90E), p.(R389H) and g.7+2G>A), and 1/3 in ABCG8 gene involving p.(M614-K628del), p.(E25X), p.(L86P fs X185), p.(R263Q), p.(E500D fs X604) and p.(G674R) mutation. The ABCG5 p.(R446X) mutation was found in 3 separate families. Conclusions: The phenomena of thrombocytopenia/ stomatocyte/splenomegaly represents a special clinical manifestations of phytosterolemia, and distinct changes of blood cell morphology are the typical characters. Plasma plant sterols and ABCG5/ABCG8 genes should be analyzed when such hematologic abnormalities are unexplained.

Abstract
A novel 60-channel electron cyclotron emission (ECE) radiometer has been designed and tested for the measurement of electron temperature profiles on the HL-2A tokamak. This system is based on the intermediate frequency division technique, and has the features of wide working frequency range (60−90 GHz) and high temporal-spatial resolution (3 µs, 1 cm), which covers almost the entire plasma region. Also, an electron cyclotron emission imaging (ECEI) system has been developed for studying two dimensional electron temperature fluctuations. It is comprised of several front-end quasi-optical lenses, a 24 channel heterodyne imaging array with a tunable RF frequency range spanning 60−135 GHz, and a set of back-end ECEI electronics that together generate two 24×8 array images of the 2nd harmonic X-mode electron cyclotron emission from the HL-2A plasma. The measurement region can be flexibly shifted due to two independent local oscillator sources, and the field of view can be adjusted easily by changing the position of the zoom lenses as well. The temporal resolution is about 2.5 µs and the achievable spatial resolution is 1 cm. The ECE/ECEI diagnostics have been demonstrated to be powerful tools to study MHD-related physics including the multi-scale interaction between macro-scale MHD and micro-scale turbulence on the HL-2A tokamak.

Abstract
Objective: To assess the quality of the clinical practice guideline for diagnosis, treatment and prevention of pulmonary thromboembolism, 2018 in China, providing the references for updating and developing clinical practice guidelines of this field in the future. Methods: The quality of the clinical practice guideline for diagnosis, treatment and prevention of pulmonary thromboembolism, 2018 in China was assessed using the internationally recognized instrument Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ). AGREE Ⅱ instrument consisted of 23 items in six domains, followed by two overall assessment items. Each item was scored from 1 to 7. The final overall guideline quality considered all domain items. Results: The scores of the six AGREE Ⅱ domains were: Scope and purpose 76.4%, Stakeholder involvement 55.6%, Rigor of development 78.1%, Clarity and presentation 83.3%, Applicability 55.2%, and Editorial independence 66.7%. The guideline was recommended for clinical use. Among the 101 recommendations, recommendations based on Levels High, Moderate and Low evidence accounted for 7 (6.9%), 31 (30.7%) and 63 (62.4%), respectively. Conclusion: The methodological quality of the clinical practice guideline for diagnosis, treatment and prevention of pulmonary thromboembolism, 2018 in China was great, but the levels of evidence were not high. More efforts were urgently required to improve in Stakeholder involvement and applicability. Especially corresponding economic research evidence, as well as preferences of patients and the public should be considered in the future development of clinical practice guidelines.

Abstract
Objective: To observe the efficacy and safety between Pegfilgrastim (PEG-rhG-CSF) and Recombinant human granulocyte colony stimulating factor (rhG-CSF) in hematological malignancy after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: 157 patients after allo-HSCT were enrolled in this study from June 2015 to November 2016. Two agents of G-CSF were used to stimulate hematopoietic recovery after transplantation. There were 65 cases in PEG-rhG-CSF and 92 cases in rhG-CSF groups. Patients in PEG-rhG-CSF group were given a single subcutaneous dose of 6 mg on the first day and +8 d, while cases in rhG-CSF group were given in dose of 5 μg·kg(-1)·d(-1) by subcutaneous injection from +1 d continuing to neutrophils more than 1.5×10(9)/L, and then the indicators and survival rates in two groups after transplantation were compared. Results: ①There were no significant differences of the neutrophil implantation time[13.5 (8-12) d vs 13 (9-24) d, P=0.393] and platelet implantation time [14 (9-160) d vs 14 (9-92) d, P=0.094] between PEG-rhG-CSF and rhG-CSF groups respectively. There were no significant differences in terms of neutropenia period (P=0.435) , number of cases who got fever during neutropenia (P=0.622) , and the median time of fever in neutropenia period (P=0.460) , respectively between the two groups. There were no significant differences of erythrocyte and platelet transfusions (P=0.074, P=0.059) within 1 month after transplantation. ②There were no significant differences with regard to the incidences of acute GVHD[23.1% (15/65) vs 34.8% (32/92) , P=0.115], chronic GVHD[20.0% (13/65) vs 32.6% (32/92) , P=0.081], Ⅱ-Ⅳdegree of acute GVHD[30.0% (13/65) vs 30.4% (30/92) , P=0.287] and extensive chronic GVHD[9.2% (6/65) vs 20.7% (19/92) , P=0.135] between PEG-rhG-CSF and rhG-CSF groups. ③There were no significant differences in terms of disease free survival (DFS) (62.5% vs 61.4%, P=0.478) and overall survival (OS) (67.4% vs 67.3%, P=0.718) between PEG-rhG-CSF and rhG-CSF groups. ④There was no significant difference of the non-relapse mortality (NRM) between PEG-rhG-CSF and rhG-CSF groups[20.5% (95%CI 11.4%-37.0%) vs 32.6% (95%CI 22.2%-47.9%) , P=0.141]. The relapse rate was not statistically significant[14.9% (95%CI 7.4%-29.8%) vs 10.0% (95%CI 5.0%-20.0%) , P=0.299]. Conclusion: Compared with rhG-CSF, PEG-rhG-CSF could reduce the times of injection. There were no differences in terms of hematopoietic recovery, the incidence of GVHD, relapse rate, DFS and OS rates after allo-HSCT between two groups.

Abstract
The safety of food additives has been widely concerned. Using single additives in the provisions of scope is safe, but the combination of additives, may induce additive, synergy, antagonism and other joint effects. This study investigated the cytotoxicity of aspartame (AT) together with potassium sorbate (PS). Thiazolyl Blue Tetrazolium Bromide (MTT) assay indicated that AT and PS had IC50 values of 0.48 g/L and 1.25 g/L at 24 h, respectively. High content analysis (HCA) showed that both AT and PS had a negative effect on mitochondrial membrane potential (MMP), reactive oxygen species (ROS) and DNA damage while the joint group behaved more obviously. The biochemical assays revealed typical cell morphological changes and the activation of cytochrome c and caspase-3 verified apoptosis induced by AT together with PS. With dissipation of MMP and increase of cell membrane permeability (CMP), it indicated AT together with PS-induced apoptosis was mediated by mitochondrial pathway. Meanwhile, p53 were involved in DNA damage, and the ratio of Bax/Bcl-2 was increased. Moreover, excessive ROS induced by AT together with PS is a key initiating factor for apoptosis. All these results proved that p53 was involved in apoptosis via mitochondria-mediated pathway and the process was regulated by ROS.

Abstract
OBJECTIVE To systematically assess the prevalence of frailty, including prefrailty, stratified prevalence according to frailty criteria, gender, age, and region, and the risk factors for frailty in China. DESIGN We conducted a systematic literature review and meta-analysis using articles available in 8 databases including PubMed, Cochrane Library, Web of Science, CINAHL Plus, China Knowledge Resource Integrated Database (CNKI), Wanfang Database, Chinese Biomedical Database (CBM), and Weipu Database (VIP). SETTING Cross-sectional and cohort data from Chinese community. PARTICIPANTS Community-dwelling adults aged 65 and older. MEASUREMENTS Two authors independently extracted data based upon predefined criteria. Where data were available we conducted a meta-analysis of frailty parameters using a random-effects model. RESULTS We screened 915 different articles, and 14 studies (81258 participants) were ultimately included in this analysis. The prevalence of frailty and prefrailty in individual studies varied from 5.9% to 17.4% and from 26.8% to 62.8%, respectively. The pooled prevalence of frailty and prefrailty were 10% (95% CI: 8% to 12%, I2 = 97.4%, P = 0.000) and 43% (95% CI: 37% to 50%, I2 = 98.0%, P = 0.000), respectively. The pooled frailty prevalence was 8% for the Fried frailty phenotype, 12% for the frail index, and 15% for the FRAIL scale. Age-stratified meta-analyses showed the pooled prevalence of frailty to be 6%, 15%, and 25% for those aged 65-74, 75-84, and ≥85 years old, respectively. The pooled prevalence of frailty was 8% for males and 11% for females. The pooled prevalence of frailty in Mainland China, Taiwan, and Hong Kong was 12%, 8%, and 14%, respectively. The pooled frailty prevalence was 10% in urban areas and 7% in rural areas. After controlling for confounding variables, increasing age (OR = 1.28, 95% CI: 1.2 to 1.36, I2 = 98.0%, P = 0.000), being female (OR = 1.29, 95% CI: 1.16 to 1.43, I2 =92.7%, P=0.000), activities of daily living (ADL) disability (OR = 1.72, 95% CI: 1.57 to 1.90, I2 = 99.7%, P = 0.000), and having three or more chronic diseases (OR = 1.97, 95% CI: 1.78 to 2.18, I2 = 97.5%, P = 0.000) were associated with frailty. CONCLUSIONS These findings of this review indicate an overall pooled prevalence of frailty among Chinese community-dwelling older people of 10%. Increasing age, being female, ADL disability, and having three or more chronic diseases were all risk factors for frailty. Further research will be needed to identify additional frailty risk factors in order to better treat and prevent frailty in the community.
