Abstract
The efficient delivery of therapeutic proteins to tumor sites is a promising cancer treatment modality. Hydrogen-bonded organic frameworks (HOFs) have been successfully used for the protective encapsulation of proteins; however, easy precipitation and lack of controlled release of existing HOFs limit their further application for protein delivery in vivo. In this study, a hypoxia-responsive HOF, self-assembled from azobenzenedicarboxylate/polyethylene glycol-conjugated azobenzenedicarboxylate and tetrakis(4-amidiniumphenyl)methane through charge-assisted hydrogen-bonding, is developed for systemic protein delivery to tumor cells. The newly generated HOF platform efficiently encapsulates representative cytochrome C, demonstrating good dispersibility under physiological conditions. Moreover, it can respond to overexpressed reductases in the cytoplasm under hypoxic conditions, inducing fast intracellular protein release to exert therapeutic effects. The strategy presented herein can be applied to other therapeutic proteins and can be expanded to encompass more intrinsic tumor microenvironment stimuli. This offers a novel avenue for utilizing HOFs in protein-based cancer therapy. This article is protected by copyright. All rights reserved.

Abstract
BACKGROUND This study aimed to investigate the clinical characteristics and prognosis of refractory peritoneal dialysis (PD)-associated peritonitis as well as the risk factors of its occurrence and treatment failure. METHODS A single-center retrospective cohort study was conducted among 519 patients undergoing PD from January 2007 to October 2021. According to the International Society for Peritoneal Dialysis guidelines, all episodes occurred in our center were divided into two groups: refractory and nonrefractory. Demographic, biochemical, and pathogenic bacteria and treatment outcome data were collected. RESULTS During the 15-year period, 282 episodes of peritonitis occurred in 166 patients undergoing PD. The refractory rate was 34.0% (96/282). Gram-positive organisms were the leading cause of peritonitis (47.9%); however, gram-negative organisms were predominant in refractory peritonitis (34.4%, p = 0.002). Multiple logistic regression revealed that gram-negative organism-based peritonitis, longer PD duration, and female sex were the significant independent predictors of refractory peritonitis. Among 96 refractory episodes, white blood cell (WBC) count, dialysate WBC on Day 3, and PD duration ≥5 years were the independent risk factors of treatment failure. CONCLUSIONS Gram-negative organism-based peritonitis, longer PD duration, and female sex were the independent risk factors of refractory peritonitis. Refractory peritonitis with higher WBC count, higher dialysate WBC on Day 3, and PD duration ≥5 years increased treatment failure risk and required immediate PD catheter removal. The timely identification of refractory peritonitis with high risk of treatment failure as well as timely PD catheter removal is important.

Abstract
Hydrogen-bonded organic frameworks (HOFs) have shown promise in various fields; however, the construction of HOF/polymer hybrid membranes that can maintain both structural and functional integrity remains challenging. In this study, we here fabricated a new HOF (HOF-50) with reserved polymerizable allyl group via charge-assisted H-bonds between the carboxylate anion and amidinium, and subsequently copolymerized the HOF with monomers to construct a covalently bonded HOF/polymer hybrid (polyHOF) membrane. The resulting polyHOF membrane not only exhibits customizable mechanical properties and extreme stability, but also shows an exceptional ratiometric luminescent temperature-sensing function with very high sensitivity and visibility even when the lanthanide content is two orders of magnitude lower than that of the reported mixed-lanthanide metal-organic frameworks (MOFs) and lanthanide-doped covalent organic frameworks (COFs). This orthogonal postsynthesis copolymerization strategy may provide a general approach for preparing covalently connected HOF/polymer hybrid membranes for diverse applications.

Abstract
BACKGROUND Angiotensin converting enzyme 2 (ACE2) exerts renoprotective effects in diabetic kidney disease (DKD) by converting angiotensin (Ang) II into Ang (1-7). Previous studies have demonstrated that ACE2 expression in renal tubules is downregulated in DKD, but the mechanism is not fully understood. Sirtuin-1 (Sirt1) is a protein deacetylase that may regulate the activity of the renin-angiotensin system. The present study investigated the effects of Sirt1 on ACE2 expression under high glucose (HG) conditions and the underlying signaling pathway. METHODS AND RESULTS Rats with DKD and NRK-52E cells cultured with HG were employed in this study. Western blotting, immunohistochemistry detection and qRT-PCR were performed for protein and mRNA expression analyses. Rats subjected to DKD displayed downregulated expression of Sirt1 and ACE2 in kidneys. Resveratrol, an activator of Sirt1, restored ACE2 expression and ameliorated renal injuries. Similarly, pharmacological activation of Sirt1 with SRT1720 markedly upregulated ACE2 in NRK-52E cells cultured with HG, while Sirt1 small interfering RNA (siRNA) further suppressed ACE2 expression. In addition, A disintegrin and metalloproteinase (ADAM) 17 was observed to be upregulated, and its inhibitor, tissue inhibitor of metalloproteinase 3 (TIMP3), was downregulated in the kidneys of diabetic rats and NRK-52E cells incubated with HG. The TIMP3/ADAM17 pathway was involved in the regulation of ACE2 expression, as evidenced by decreased ACE2 expression levels after TIMP3-siRNA pretreatment. SRT1720 ameliorated the imbalance of TIMP3/ADAM17 induced by HG and consequently enhanced the expression of ACE2. Notably, the above effect of SRT1720 on ACE2 was interrupted by TIMP3-siRNA. CONCLUSIONS Our findings suggest that Sirt1 activation may prevent HG-induced downregulation of renal tubular ACE2 by modulating the TIMP3/ADAM17 pathway. Sirt1 stimulation might be a potential strategy for the treatment of DKD.

Abstract
Objective: To investigate whether heat shock protein 90 (HSP90) participates in the necroptosis of C57BL/6 mouse neurons and spatial memory impairment induced by Aluminum maltol [Al (mal) (3)] through RIP1/RIP3/MLKL pathway. Methods: In March 2022, Thirty-two C57 mice were randomly divided into control group, Low dose group, a medium dose group, and a high-dose group, with 8 mice in each group, and injected intraperitoneally with physiological saline, 20, 40, and 80, respectivelyμmol/kgAl (mal) (3) was administered, it was injected 5 days a week and discontinued 2 days for 60 days. Morris water maze test was used to test the spatial learning and memory ability of mice. Nissl staining was used to observe the pathological changes of brain tissue. The protein expression levels of RIP1, RIP3, MLKL and HSP90 in hippocampus were determined by Western blotting. Results: In the water maze experiment, compared with the control group, the number of mice crossing the platform decreased in each dose group, the difference was statistically significant (H=9.50, P=0.023), and the number of mice crossing the platform was statistically significant among each dose group (P <0.05). Compared with the control group, the number of hippocampal nerve cells in each dose group decreased, the arrangement was disordered, and the Nissellite bodies decreased. Western blotting results showed that compared with the control group, the expression level of RIP1 protein in the hippocampus of mice in high-dose group was higher, and the difference was statistically significant (P <0.05). The expression levels of RIP3, MLKL and HSP90 in hippocampal tissue of mice in medium and high dose groups were increased, and the differences were statistically significant (P<0.05). After siRNA intervention decreased the expression of HSP90 protein, the expressions of HSP90, RIP1, RIP3 and MLKL in Al (mal) (3) groups were increased, and the differences were statistically significant (P<0.05) . Conclusion: Through RIP1/RIP3/MLKL pathway, HSP90 is involved in neuronal programmed necrosis and spatial memory impairment induced by maltol aluminum in C57 mice.

Abstract
BACKGROUND Peritoneal dialysis (PD)-associated peritonitis is a serious complication observed in peritoneal dialysis patients. Herein, we investigated the clinical characteristics and treatment outcomes of PD peritonitis in patients with different PD durations. METHODS All peritonitis episodes from January 2007 to December 2020 at Peking University People's hospital PD center were retrospectively analyzed and divided into the long-dialysis duration (≥60 months, LDD) and short-dialysis duration (<60 months, SDD) groups. Clinical characteristics and outcomes were compared between these groups. The risk factors for treatment failure were analyzed using a logistic regression model. RESULTS During 14 years, 156 patients had 267 peritonitis episodes. There were 83 (31.1%) peritonitis episodes in the LDD group and 184 (68.9%) in the SDD group. No statistical difference was noted in peritonitis causes and the composition of causative pathogens between the two groups. The hospitalization, treatment failure, and transfer-to-hemodialysis rates, and peritonitis-related mortality were significantly higher in the LDD group than in the SDD group (all p < .05). Logistic regression analysis revealed that PD duration was an independent risk factor for PD-associated hospitalization, treatment failure and peritonitis-related death (p < .05). The receiver operating characteristic curve analysis results showed that when the cutoff value of PD duration was 5.5 years, the sensitivity of predicting PD peritonitis treatment failure was 51.1%, specificity was 78.8%, and the area under the curve was 0.679 (95% confidence interval: 0.594-0.765, p < .001). CONCLUSIONS PD duration is an independent risk factor for poor prognosis in PD peritonitis. Careful and active attention should be paid to the prevention of peritonitis in PD patients with long PD duration.

Abstract
Introduction Congestive heart failure (CHF) is one of the common complications in patients with end-stage kidney disease. In the general population, CHF increases the risk of the death. However, there is no well-designed relevant study in the Chinese hemodialysis (HD) population addressing the risks associated with CHF. The aim of this study was to explore the impact of CHF on clinical outcomes in HD patients. Methods Data from a prospective cohort study, the China Dialysis Outcomes and Practice Patterns Study (DOPPS) 5 (2012-2015), were analyzed. Demographic data, comorbidities, lab data, and death records were extracted. CHF was defined by the diagnosis records upon study inclusion. Our primary outcome was all-cause and cardiovascular (CV) mortality; secondary outcomes were all-cause and cause-specific hospitalization risk. Associations between CHF and outcomes were evaluated using Cox regression models. Stepwise multivariate logistic regression was used to identify the related risk factors, and subgroup analyses were carried out. Results Of 1,411 patients without missing CHF history information, 24.1% (340) had CHF diagnosis at enrollment. The overall mortality rates were 21.8% versus 12.0% (p < 0.001) in patients with and without CHF during follow-up, respectively. CHF was associated with higher all-cause mortality (adjusted HR: 1.72, 95% confidence interval [CI]: 1.17-2.53, p = 0.006), and the association with CV death was of similar magnitude (HR: 1.60, 95% CI: 0.91-2.81, p = 0.105). CHF patients had more episodes of hospitalization due to heart failure (HR: 2.93, 95% CI: 1.49-5.76, p < 0.01). However, compared with patients without CHF, the all-cause hospitalization risk was not much higher in CHF patients (HR: 1.09, 95% CI: 0.90-1.33, p = 0.39). Subgroup analysis found that the effect of CHF on all-cause mortality was stronger for male patients, patients with residual renal function, the elderly (≥60 years of age), patients with arteriovenous fistulae vascular accesses, nondiabetic patients, low-flux dialyzer users, and inadequately dialyzed patients (standardized Kt/V <2). Conclusion In HD patients, CHF was found to be associated with a higher risk of all-cause mortality and cause-specific hospitalization risk. Further research is needed to identify opportunities to improve care for HD patients combined with CHF.

Abstract
Objective: To investigate the effect and mechanism of miR-96-5p on apoptosis of PC12 cells induced by maltol aluminum. Methods: In January 2021, PC12 cells at logarithmic growth phase were divided into blank control group and low, medium and high dose group. Cells in each group were treated with 0, 100, 200 and 400 μmol/L maltol aluminum for 24 hours respectively. Cells were collected and cell apoptosis rates were detected by flow cytometry, miR-96-5p and insulin receptor substrate 1 (IRS1) mRNA expressions were detected by qRT-PCR, and the protein expression levels of cysteine protease 3 (Caspase3) 、activated cysteine protease 3 (Cleaved-caspase3) 、IRS1、phosphorylated protein kinase B (p-AKT) and phosphorylated glucose synthesis kinase 3β (p-GSK3β) were detected by western blotting. The target binding relationship between miR-96-5p and IRS1 was detected by double luciferase reporter gene experiment. The miR-96-5p inhibitor cells and negative control cells were constructed after transfecting PC12 cells with miR-96-5p inhibitor for 24 hours. The cells were divided into blank control group, negative control group, aluminum exposure group, aluminum exposure+negative control group, aluminum exposure+miR-96-5p inhibition group, and miR-96-5p inhibition group. After transfecting PC12 cells with miR-96-5p inhibition and IRS1 siRNA for 24 h, the cells were divided into aluminum exposure+miR-96-5p inhibition+negative control group and aluminum exposure+miR-96-5p inhibition+IRS1 inhibition group. The control group was cultured in complete culture medium, and cells in the aluminum exposure group were treated with 200 μmol/L maltol aluminum for 24 hours. Cells in each group were collected and the apoptosis rate, miR-96-5p and IRS1 mRNA expression levels, as well as protein expression levels of Caspase3, Cleaved-caspase3, IRS1, p-AKT, and p-GSK3β were measured. Results: After 24 hours of exposure, compared with blank control group and low-dose group, the apoptosis rates, relative expressions of Caspase3 and Cleaved-caspase3 proteins, and relative expressions of miR-96-5p in the medium and high-dose groups of PC12 cells were significantly increased, while the relative expression levels of IRS1 mRNA, IRS1, p-AKT and p-GSK3β proteins were significantly decreased (P<0.05). Targetscan prediction and double luciferase report experiment both proved that IRS1 was a direct target gene of miR-96-5p. In the transfection experiment, compared with the aluminum exposure group, the apoptosis rate, the relative expressions of Caspase3 and Cleaved-caspase3 proteins, the relative expression of miR-96-5p in the aluminum exposure+miR-96-5p inhibition group were significantly decreased, while the relative expression levels of IRS1 mRNA and IRS1, p-AKT and p-GSK3β proteins were significantly increased (P<0.05). In the IRS1 low expression experiment, compared with the aluminum exposure+miR-96-5p inhibition+negative control group, the apoptosis rate, the relative expressions of Caspase3 and Cleaved-caspase3 proteins in the aluminum exposure+miR-96-5p inhibition+IRS1 inhibition group were significantly increased, while the relative expression levels of IRS1 mRNA and IRS1, p-AKT and p-GSK3β proteins were significantly decreased (P<0.05) . Conclusion: The increased expression of miR-96-5p and the targeted inhibition of IRS1 may be one of the mechanisms of apoptosis of PC12 cells induced by maltol aluminum exposure.

Abstract
The self-healing of glassy polymer materials on site has always been a huge challenge due to their frozen polymer network. We herein report self-repairable glassy luminescent film by assembling a lanthanide-containing polymer with randomly hyperbranched polymers possessing multiple hydrogen (H) bonds. Because of multiple H bonds, the hybrid film exhibits enhanced mechanical strength, with high glass transition temperature (Tg) of 40.3 °C and high storage modulus of 3.52 GPa, meanwhile, dynamic exchange of multiple H bonds enables its rapid room-temperature self-healing ability. This research provides new insights in preparing mechanical robust yet repairable polymeric functional materials.

Abstract
(1) Background: Recently more and more Chinese clinical studies have been conducted to compare the efficacy and safety of roxadustat with erythropoiesis-stimulating agents (ESAs) in hemodialysis (HD) patients. We aimed to assess the efficacy and safety of roxadustat in Chinese HD patients. (2) Methods: The PubMed, Embase, the Cochrane Library, Web of Science, WanFang, China National Knowledge Infrastructure (CNKI), SinoMed, and VIP databases were searched from their inception to July 2022 for randomized controlled trials (RCTs) that compared the efficacy and safety of roxadustat to those of ESAs in treating anemia in Chinese HD patients. (3) Results: Twenty-one RCTs involving 1408 patients were enrolled. Our study showed that the improvement of hemoglobin (Hb) levels and iron metabolism were significantly higher in the roxadustat group than in the ESA group. Additionally, the total adverse events risk was significantly lower in the roxadustat group. (4) Conclusions: In this meta-analysis, we found that roxadustat was more effective and safer than ESAs in treating anemia in Chinese HD patients.

Abstract
The development of repairable MOF-polymer hybrid materials will greatly extend their service life by repairing fractured parts on the spot; however, it is difficult for robust glassy polymers to self-heal below the glass transition temperature (Tg) as the polymer network is frozen. We herein report glassy polyMOF-RHP hybrid membranes by integrating lanthanide polyMOF (polyLnMOF) with randomly hyperbranched polymers (RHP) bearing a high density of hydrogen bonds. Since crystalline lanthanide MOFs act as multiconnected cross-linking agents and cross-link the interpenetrating polymer network, the obtained polyLnMOF-polymer membrane shows enhanced mechanical strength with a storage modulus of 3.09 GPa and a Tg up to 49 °C. Meanwhile, the high intersegment migration ability of the polyLnMOF-polymer network facilitates the exchange of hydrogen-bonded pairs even in the glassy state, leading to an instantaneous room-temperature self-healing ability. The polyLnMOF-polymer membranes inherit the ratiometric temperature-sensing behavior of pristine lanthanide MOFs, resulting in more processable temperature-sensing membranes. This work provides an appealing strategy for the design of mechanically robust, yet self-healing, MOF-polymer functional materials.

Abstract
AIM To investigate the diagnostic value of quantitative susceptibility mapping (QSM) in mild cognitive impairment (MCI) of aluminium (Al) workers. MATERIALS AND METHODS The basic data of 53 workers in an Al factory were collected and divided into the MCI group and normal control (NC) group by Montreal Cognitive Assessment (MoCA) scores. All participants were tested for plasma Al concentration and had magnetic resonance imaging (MRI). The QSM values of many areas of the brain were delineated and measured. Independent two-sample t-tests or non-parametric tests were used to compare the parameter values between the two groups. Spearman's correlation analysis was performed between QSM values, MoCA scores, and plasma Al concentration. The receiver operating characteristic curve and z test were performed to assess diagnostic efficacy and the best parameter. RESULTS There was no difference in age and educational level. Plasma Al concentration of the MCI group was higher than that of NC group (p=0.057). QSM values of the left hippocampus, left dentate nucleus, right substantia nigra, and left putamen in MCI group were higher than that of NC group (p<0.05), and the left hippocampus had the best diagnostic efficacy. QSM values correlated negatively with MoCA scores. No correlation was found between QSM values and plasma Al concentration (p>0.05). CONCLUSION QSM might be a neuroimaging marker for the diagnosis of MCI. The left hippocampus showed the best diagnostic efficacy. Plasma Al concentration of the MCI group was higher than that of the NC group. A correlation between QSM and plasma Al concentration was not found.

Abstract
Abstract
BACKGROUND AND AIMS
Hemodialysis (HD) is a unique treatment modality that offers a life-sustaining treatment option for patients with end-stage kidney disease (ESKD). However, the mortality of HD patients is still unacceptably high compared with the general population. Cardiovascular diseases (CVDs) (including myocardial infarction, heart failure and stroke) are the leading causes of death in dialysis-dependent ESKD patients, accounting for ∼40% of the mortality. Congestive heart failure (CHF) is a final common clinical pathway for several diseases. HD patients are at 12–36× risk for the development of CHF. In the general population, CHF increases the risk of death. However, there is no well-designed relevant study in the Chinese HD population addressing the risks associated with CHF. The aim of this study was to explore the impact of CHF on the clinical outcomes in HD patients.
METHOD
The DOPPS is an international prospective cohort study of in-center adult HD patients. China joined DOPPS in 2011. DOPPS China randomly selected an average of 30 patients from 15 dialysis facilities in each city of Beijing, Shanghai and Guangzhou. There were 1427 patients who participated in China DOPPS5 (2012–2015). Of the 1427 patients, 16 patients were excluded from the present analysis as their CHF history information was missing. Demographic data, comorbidity, Lab data and death records were extracted. CHF was defined by the diagnosis records upon study inclusion. Continuous variables were represented as mean ± SD or median (25th, 75th) according to the results of the normality test. Categorical variables were expressed as numbers and percentages. We stratified data by CHF and non-CHF groups. Our primary outcome was associations between CHF and all-cause and cardiovascular (CV) mortality; secondary outcomes were all-cause and cause-specific hospitalization risk. Associations between CHF and outcomes were evaluated using Cox regression models. Cox regression models were with five incremental levels of covariate adjustment. Stepwise multivariate logistic regression was used to identify the related risk factors, and subgroup analyses were carried out.
RESULTS
Of 1411 patients without missing CHF history information, 24.1% (340) had a CHF diagnosis at enrollment. In this cohort, male patients accounted for 54.9% of the patients. The median age was 60.0 (inter-quartile range, IQR 49.0–71.0) years and the median dialysis vintage was 2.6 (IQR 0.9–5.4, Table 1) years. The median follow-up period was 1.9 (IQR 1.2–2.1) years. Altogether, 203 (14.4%) patients died, where 103 (7.3%) died from CV disease. The CV death constituted half of the patient’s mortality. The overall mortality rates were 21.8% versus 12.0% (P < 0.001) in patients with and without CHF during entire follow-up, respectively. CHF was associated for higher all-cause mortality [adjusted HR 1.72, 95% confidence interval (95% CI) 1.17–2.53; P = 0.006, Fig. 1], and the association with CV death was of similar magnitude (HR 1.60, 95% CI 0.91–2.81; P = 0.105). CHF patients had more episodes of hospitalization due to heart failure (HR 2.93, 95% CI 1. 49– 5.76; P <0.01). However, compared with patients without CHF, the all-cause hospitalization risk was not much higher in CHF patients (HR 1.09, 95% CI 0.90–1.33; P = 0.39).
CONCLUSION
In this prospective cohort study, the prevalence of CHF was identified to be around one quarter, and all-cause mortality in patients with combined CHF and HD was found to be higher. CHF was associated with an increased risk of all-cause mortality and a cause-specific hospitalization risk in HD patients. The associations were not affected by adjustment for several potential confounding factors. Thus, CHF is found to be an outcome predictor for HD patients, and measures should be adopted to improve care for these patients to improve their survival.

Abstract
Background Expanded hemodialysis (HDx) is a new dialysis modality, but a systematic review of the clinical effects of using HDx is lacking. This systematic review and meta-analysis aimed to assess the efficacy and safety of HDx for hemodialysis (HD) patients. Methods PubMed, the Cochrane library, and EMBASE databases were systematically searched for prospective interventional studies comparing the efficacy and safety of HDx with those of high flux HD or HDF in HD patients. Results Eighteen trials including a total of 853 HD patients were enrolled. HDx increased the reduction ratio (RR) of β2-microglobulin (SMD 6.28%, 95% CI 0.83, 1.73, p = .02), κFLC (SMD 15.86%, 95% CI 6.96, 24.76, p = .0005), and λFLC (SMD 22.42%, 95% CI, 17.95, 26.88, p < .0001) compared with high flux HD. The RR of β2-microglobulin in the HDx group was lower than that in the HDF group (SMD −3.53%, 95% CI −1.16, −1.9, p < .0001). HDx increased the RRs of κFLC (SMD 1.34%, 95% CI 0.52, 2.16, p = .001) and λFLC (SMD 7.28%, 95% CI 1.08, 13.48, p = .02) compared to HDF. There was no significant difference in albumin loss into the dialysate between the HDx and HDF groups (SMD 0.35 g/session, 95% CI −2.38, 3.09, p = .8). Conclusions This meta-analysis indicated that compared with high-flux HD and HDF, HDx can increase the clearance of medium and large-molecular-weight uremic toxins. And it does not increase the loss of albumin compared with HDF.

Abstract
BACKGROUND Hemodialysis (HD) patients have a higher mortality rate compared with general population. Our previous study revealed that platelet counts might be a potential risk factor. The role of platelets in HD patients has rarely been studied. The aim of this study is to examine if there is an association of thrombocytopenia (TP) with elevated risk of all-cause mortality and cardiovascular (CV) death in Chinese HD patients. METHODS Data from a prospective cohort study, China Dialysis Outcomes and Practice Patterns Study (DOPPS) 5, were analyzed. Demographic data, comorbidities, platelet counts and other lab data, and death records which extracted from the medical record were analyzed. TP was defined as the platelet count below the lower normal limit (< 100*109/L). Associations between platelet counts and all-cause and CV mortality were evaluated using Cox regression models. Stepwise multivariate logistic regression was used to identify the independent associated factors, and subgroup analyses were also carried out. RESULTS Of 1369 patients, 11.2% (154) had TP at enrollment. The all-cause mortality rates were 26.0% vs. 13.3% (p < 0.001) in patients with and without TP. TP was associated with higher all-cause mortality after adjusted for covariates (HR:1.73,95%CI:1.11,2.71), but was not associated with CV death after fully adjusted (HR:1.71,95%CI:0.88,3.33). Multivariate logistic regression showed that urine output < 200 ml/day, cerebrovascular disease, hepatitis (B or C), and white blood cells were independent impact factors (P < 0.05). Subgroup analysis found that the effect of TP on all-cause mortality was more prominent in patients with diabetes or hypertension, who on dialysis thrice a week, with lower ALB (< 4 g/dl) or higher hemoglobin, and patients without congestive heart failure, cerebrovascular disease, or hepatitis (P < 0.05). CONCLUSION In Chinese HD patients, TP is associated with higher risk of all-cause mortality, but not cardiovascular mortality. Platelet counts may be a useful prognostic marker for clinical outcomes among HD patients, though additional study is needed.

Abstract
Objective: To evaluate the effects of occupational aluminum exposure on workers' overall cognitive function and cognitive fields. Methods: From July to August 2019, using the method of cluster sampling, 101 and 117 workers were selected from the electrolytic aluminum workshop of an aluminum plant in a region and the maintenance workshop of a plant in the same region. The venous blood of the subjects was collected, the plasma was extracted, and the blood aluminum concentration was measured by ICP-MS. According to the blood aluminum concentration and type of work, 93 workers who were lower than the median blood aluminum concentration and in the maintenance workshop of a factory were divided into low aluminum exposure group, and 85 workers who were higher than the median blood aluminum concentration and in the electrolytic aluminum workshop of an aluminum factory were divided into high aluminum exposure group. The basic information of the respondents, was collected through the employee physical examination form. The overall cognitive function of workers was evaluated by Beijing Montreal Cognitive Assessment Scale (MoCA) . Multiple linear regression analysis and logistic regression analysis were used for multiple statistical analysis. Results: Compared with the low aluminum exposure group (25.42±1.808) , the total score of MoCA in the high aluminum exposure group (23.84±2.919) was significantly lower, and the scores of visual space, executive function, abstract and delayed recall were significantly lower (P<0.05) . Linear regression analysis showed that the total score of MoCA, visual space and executive function, naming and delayed recall were negatively correlated with blood aluminum concentration (β=-0.018、-0.008、-0.003、-0.008, P<0.05) .MOCA total score, visual space and executive function, attention, language, abstraction, orientation were positively correlated with educational level (β=0.853、0.310、0.216、0.171、0.412、0.122, P<0.05) . Logistic regression analysis showed that adjusting for age, smoking, drinking and education, blood aluminum was a risk factor for mild cognitive impairment (OR=1.017, P<0.05) ; Education level was the protective factor of mild cognitive impairment (OR=0.419, P<0.05) . Conclusion: Occupational aluminum exposure can affect the overall cognitive function of workers, and occupational aluminum exposure increases the risk of MCI.

Abstract
Objective: To explore the effect of occupational aluminum (Al) exposure on workers' overall cognitive level and speech function. Methods: In July 2019, by using cluster sampling method, the group of 232 exposed to Al from an Al plant in Shanxi Province were selected as the exposed group, and the group of 228 not exposed to Al were selected as the control group. The blood Al concentration was determined by inductively coupled plasma mass spectrometry (ICP-MAS) . The exposed group was divided into high exposure group and low exposure group according to the median (M) concentration of Al in serum. The general cognitive function and speech function were evaluated with the Montreal Cognitive Assessment Scale (MoCA) , and the differences in the general cognitive function and speech function between the groups were compared, and non-conditional logistic regression was used to analyze the possible influencing factors of mild cognitive impairment (MCI) . Results: There were significant differences in age, working age, education and drinking status between Al exposed group and control group (P<0.05) . The total MoCA score, animal naming tese (ANT) score and category fluency repetition (CFT) score in Al exposure group were lower than control group and the differences were statistically significant (P<0.05) . The full rate of ANT was lower than that of CFT in Al exposure group (P<0.05) . The total MoCA score, ANT score and CFT score in the high exposure group were significantly lower than those in the control group (P<0.05) . The score of MoCA, ANT and CFT in high exposure group were lower than those in low exposure group between the level of serum aluminum>60 μg/L group and ≤60 μg/L group (P<0.05) . Logistic regression analysis showed that working age, serun Al concentration, ANT score, CFT score and SR score were the possible influencing factors of MCI in occupational Al exposure workers (P<0.05) . Conclusion: Occupational Al exposure can lead to impaired speech function of workers, the higher the ANT score, CFT score and SR score, the lower working age and serum Al concentration, the lower risk of MCI.

Abstract
Luminescent hydrogels have shown great potential in many fields, such as lighting, display, imaging, and sensing, because of their unique optical properties, biocompatibility, and easy processing. Organic-inorganic hybrid self-assembly can not only enhance the hydrogels' mechanical strength, but also retain their self-healing ability. Herein, a luminescent supramolecular hydrogel is reported, which is formed via self-assembly of the negatively charged Laponite nanosheets and cationic lanthanide coordination polymer. The corresponding results reveal that the multiple binding interaction between Laponite and the polymeric binder is vital for improving the mechanical performance of the obtained luminescent supramolecular hydrogel.

Abstract
BACKGROUND Studies suggested the association between blood flow rate (BFR) and mortality might be beyond dialysis adequacy. This study aimed to explore if BFR is an independent predictor of clinical outcomes in Chinese hemodialysis (HD) patients. METHODS This study included data from patients in China Dialysis Outcomes and Practice Patterns Study (DOPPS) Phase 5. Patients with a record of BFR were included, and demographic data, comorbidities, hospitalization, and death records were collected. Associations between BFR and all-cause mortality and hospitalization were analyzed using Cox regression models. RESULTS One thousand four hundred twelve (98.9%) patients were included. Most patients were with BFR < 300 ml/min. After full adjustment, each 10-ml/min increase of BFR was associated with a 6.4% decrease in all-cause mortality risk (HR: 0.936, 95% CI: 0.880-0.996) but not first hospitalization (HR: 0.987, 95% CI: 0.949-1.027). The impact of BFR on mortality may be more prominent in patients who were male gender, nondiabetic, albumin < 4.0 g/dl, and hemoglobin ≥ 9.0 g/dl. CONCLUSION Increased BFR is independently associated with a lower risk of all-cause mortality within the range of BFR 200-300 ml/min. And this effect is more pronounced in patients who were male gender, nondiabetic, albumin < 4.0 g/dl, and hemoglobin ≥ 9.0 g/dl.

Abstract
Stimuli-responsive hydrogels are flourishing; however, a multiresponsive luminescent hydrogel actuator in which the stimuli do not interfere with each other is still difficult to produce. Here, a smart luminescent bilayer hydrogel actuator with shape memory and reversible luminescence switch behaviors under the co-stimulation of pH and heating is reported. Under alkaline condition, chitosan-containing layer generates physical microcrystals to fix the temporary shape of the actuator while lanthanide emits bright luminescence. Upon acid treatment, the actuator recovers to its original shape and the luminescence is quenched since the "antenna effect" between organic ligand and lanthanide ions is disrupted. It is to be noticed that this multiresponsive cycle can be repeated several times without interfering each other. This work is expected to have potential application prospects in the fields of biomimetic soft robots, sensors, and camouflage.

Abstract
Background Hemodialysis (HD) patients usually have impaired physical function compared with the general population. Self-reported physical function is a simple method to implement in daily dialysis care. This study aimed to examine the association of self-reported physical function with clinical outcomes of HD patients. Methods The Dialysis Outcomes and Practice Patterns Study (DOPPS) is a prospective cohort study. Data on 1,427 HD patients in China DOPPS5 were analyzed. Self-reported physical function was characterized by 2 items of "moderate activities limited level" and "climbing stairs limited level." Demographic data, comorbidities, hospitalization, and death records were collected from patients' records. Associations between physical function and outcomes were analyzed using COX regression models. Results Compared to "limited a lot" in moderate activities, "limited a little" and "not limited at all" groups were associated with lower all-cause mortality after adjusted for covariates (HR: 0.652, 95% CI: 0.435-0.977, and HR: 0.472, 95% CI: 0.241-0.927, respectively). And, not limited in moderate activities was associated with lower risk of hospitalization than the "limited a lot" group after adjusted for covariates (HR: 0.747, 95% CI: 0.570-0.978). Meanwhile, compared to "limited a lot" in climbing stairs, "limited a little" and "not limited at all" groups were associated with lower all-cause mortality (HR: 0.574, 95% CI: 0.380-0.865 and HR: 0.472, 95% CI: 0.293-0.762, respectively) but not hospitalization after fully adjusted. Conclusion Higher limited levels in self-reported physical function were associated with higher risk of all-cause mortality and hospitalization in HD patients.

Abstract
The derived feathering phenotype beard in domestic birds is an ideal resource to investigate the genetic mechanisms controlling feather development and differentiation. In the present study, we performed a GWAS and QTL linkage analysis on the trait of beard in Beijing fatty chicken. One major QTL (1.2-1.9 Mb) was identified that could explain 34% of the phenotypic variation. The copy number variation that was copied from the region (GGA27:3 578 409-3 592 890 bp) containing homebox B7 (HOXB7) and homebox B8 (HOXB8) was validated to be only exhibited in the genome of bearded chickens. Protein-protein interaction analysis indicated that HOXB7 and HOXB8 proteins could highly interact with the HOXB family members, including HOXB4, HOXB5 and HOXB6, whose genomic locations near HOXB7 and HOXB8 suggested that they may regulate their family members to involve in the formation of the beard trait in chickens. Overall, our work provides basic data for understanding the mechanisms regulating beard development and differentiation.

Abstract
Background Hemodialysis (HD) tend to have more hemodynamic changes than peritoneal dialysis (PD), which aggravates inflammation and oxidative stress. Whether HD and PD have different effects on the progression of vascular calcification? Therefore, we produced a study to explore the relationship of dialysis modalities and coronary artery calcification (CAC) progression. Methods This was a prospective cohort study. CT scans were performed at enrollment and 2 years later for each patient. Demographic and clinical data were collected. Tobit regression was used to compare delta CAC score between HD and PD patients. Results (1) 155 patients were enrolled, including 69 HD and 86 PD patients. (2) The baseline CAC scores were 97 (1, 744) in HD and 95 (0, 324) in PD; the follow-up CAC scores were 343 (6, 1379) in HD and 293 (18, 997) in PD. There were no significant differences in baseline, follow-up and delta CAC scores between 2 groups (P > 0.05). (3) In Tobit regression, after adjusted for variables, there was no significant difference of CAC progression in HD and PD groups (P > 0.05). (4) Logistic regression showed that older age, diabetes and higher time-averaged serum phosphate (P) were associated with faster progression of CAC (P < 0.05), but there was no evidence that HD was associated with faster CAC progression compared with PD (P = 0.879). Conclusions There was no evidence that different dialysis modalities have different effect on CAC progression. Old age, DM and higher time-averaged P were associated with fast CAC progression.

Abstract
Introduction Long‐term use of unfractionated heparin (UFH) or low‐molecular‐weight heparin (LMWH) causes bone loss and osteoporosis in patients not receiving hemodialysis. This study aimed to investigate the effect of UFH and LMWH on bone mineral density (BMD) in patients undergoing maintenance hemodialysis (MHD). Methods Patients undergoing MHD using UFH or LMWH as anticoagulants were enrolled. BMD (in g/cm2), T‐score and Z‐score (BMDs) were measured at the lumbar spine and femur neck using dual‐energy X‐ray absorptiometry (DXA) at baseline and 2 years later. Patient demographics and clinical indices were collected. Correlation analysis was used to identify significant predictors of bone loss. Multiple linear regression was used to explore the relationship between heparin type and bone loss progression. Findings A total of 104 patients were enrolled and completed the baseline BMD test; 72 completed the test again 2 years later. Six patients were excluded because they used both UFH and LMWH. Although BMD decreased in some patients in the UFH group, a slight increase in the BMD was observed on an average in the LMWH group after 2 years. The mean change in BMD (in g/cm2) [0(−0.03,0.04) vs. 0.04(0,0.06), P = 0.023], T‐score [0(−0.40,0.30) vs. 0.35(−0.03,0.53), P = 0.038], and Z‐score [0.10(−0.30,0.40) vs. 0.45(0.08,0.63), P = 0.031] in the lumbar spine in the UFH group was lower than those in the LMWH group. Femur neck BMD did not change significantly. In a linear regression model, after adjusting for diabetes mellitus, parathyroid hormone, and serum phosphate, we did not find an association between heparin substances and BMD. Discussion UFH might be associated with loss of lumbar spine BMD in patients undergoing MHD.

Abstract
Background and Aims
Mortality risk for maintenance hemodialysis (MHD) patients varies by country and ethnicity. Here, mortality rate and its related risk factors in Chinese HD patients from Dialysis Outcomes and Practice Patterns Study (DOPPS) were studied.
Method
Data from the China DOPPS phase 5 (2012-2015) were used. All included patients were followed to the end of the study. Patients’ demographics, primary cause of end stage renal disease (ESRD), comorbidities, abstracted dialysis prescription, laboratory values, date of death, and causes for death were analyzed. All-cause mortality (per 100 patient-years) was calculated. We examined clinical and laboratory differences between died and survived patients. Cox regression was used to explore risk factors of death, accounting for facility clustering and adjusted for case-mix (age, sex, vintage, and comorbid conditions), and laboratory values (albumin, hemoglobin, white blood count, sodium).
Results
There were 1427 MHD patients were enrolled. The mean age at dialysis initiation was 59.4±14.9 years (table 1). The median follow-up time was 1.9 years (IQR 1.1-2.1). There were total 205 deaths. The overall mortality rate was 8.8 per 100 patient-years. Death from cardiovascular disease (CVD) occurred in 50.2% of the patients. Compared with survived patients, patients with mortality were older (58.5 Vs. 70.0 y), more likely with diabetes, with lower pre-dialysis albumin level (Pre-ALB) or hemoglobin level (Pre-HGB), with lower pre or post dialysis diastolic blood pressure (DBP), with some comorbidities and less likely with fistula as their blood access (table 2). Cox regression revealed that risk factors for higher mortality were older age, lower Pre-ALB level, higher pre-dialysis DBP and with CHF, hepatitis, hypertension, and lung disease.
Conclusion
CVD constituted half of the death reasons for Chinese dialysis patients. Our analysis highlighted that there are some modifiable risk factors for patients’ survival. Attention should be paid to patients who were older, with lower Pre-ALB level, higher pre-dialysis DBP and with CHF, hepatitis, hypertension, and lung disease.

Abstract
Pullorum disease caused by Salmonella Pullorum is one of the most important infectious diseases in the poultry industry worldwide, which leads to serious economic losses in many developing countries because of its high mortality rate in young chicks. The traditional slide agglutination test with low cost, fast reaction, and on-site detection has been widely used in the diagnosis of Pullorum disease. However, in practice, the test performance is with the disadvantages of false positive results and unstable detection results. In this paper, we developed self-made agglutination antigens prepared by local isolates in the poultry farm and compare the detection performance with commercial agglutination antigens (China Institute of Veterinary Drug Control) and Group D Salmonella ELISA kit (BioChek UK Ltd). The results of detecting 200 serum samples indicated that the consistency of commercial agglutination antigen detecting in 2 times was only 79.5%. Using the ELISA kit as the reference method, the commercial agglutination antigen detecting results of the Kappa test were only moderately consistent (0.58 ∼ 0.59). Meanwhile, positive and total coincidence rates of the self-made agglutination antigen test with more reliable repeat could reach 97.4 and 88%, respectively, and the result of Kappa test was highly consistent (0.75). The Receiver Operating Characteristic curve analysis clarified that the area under the receiver-operating-characteristic curve values of self-made and commercial agglutination antigen tests could reach 0.861 and 0.804, respectively. These results were coincident when detecting known positive serum from the infected chickens. It's worth mentioning that the visible positive reaction of self-made agglutination antigen test appeared faster and stronger than commercial antigen test. In conclusion, self-made Salmonella Pullorum agglutination antigen developed in this study was much better than commercial agglutination antigen and is expected to be a valuable tool in the diagnosis of the epidemiology of Salmonella Pullorum.

Abstract
Transport measurements are presented up to fields of 29 T in the recently discovered heavy-fermion superconductor UTe_{2} with magnetic field H applied along the easy magnetization a axis of the body-centered orthorhombic structure. The thermoelectric power varies linearly with temperature above the superconducting transition, T_{SC}=1.5 K, indicating that superconductivity develops in a Fermi liquid regime. As a function of field the thermoelectric power shows successive anomalies which appear at critical values of the magnetic polarization. Remarkably, the lowest magnetic field instability for H∥a occurs for the same critical value of the magnetization (0.4 μ_{B}) than the first order metamagnetic transition at 35 T for field applied along the b axis. It can be clearly identified as a Lifshitz transition. The estimated number of charge carriers at low temperature reveals a metallic ground state distinct from LDA calculations indicating that strong electronic correlations are a major issue.

Abstract
BACKGROUND In recent years, there has been a growing concern that abdominal aortic calcification (AAC) has a predictive effect on the prognosis of patients with end-stage renal disease (ESRD). However, whether other vascular calcification (VC) can predict the occurrence of adverse events in patients, and whether it is necessary to assess the calcification of other blood vessels remains controversial. This study aimed to assess VC in different sites using X-ray films, and to investigate the predictive effects of VC at different sites on all-cause mortality and cardiovascular (CV) mortality in peritoneal dialysis (PD) patients. METHODS The data of Radiographs (lateral abdominal plain film, frontal pelvic radiograph and both hands radiograph) were collected to evaluate the calcification of abdominal aorta, iliac artery, femoral artery, radial artery, and finger arteries. Patients' demographic data, clinical characteristics, laboratory data were recorded. The total follow-up period was 8 years, and the time and cause of death were recorded. Survival curves were estimated using Kaplan-Meier analysis. COX regression analysis was used to examine independent predictors of all-cause mortality and CV mortality. RESULTS One hundred fifty PD patients were included, a total of 79 patients (52.7%) died at the end of follow-up. After adjusting variables in the multivariate COX regression analysis, AAC was an independent predictor of all-cause mortality in PD patients (HR = 2.089, 95% CI: 1.089-4.042, P = 0.029), and was also an independent predictor of CV mortality (HR = 4.660, 95% CI: 1.852-11.725, P = 0.001). We also found that femoral artery calcification had a predictive effect on all-cause and CV mortality. But the calcification in iliac artery, radial artery, and finger arteries were not independent predictors of patients' all-cause and CV mortality in PD patients. CONCLUSION AAC was more common in PD patients and was an independent predictor of all-cause mortality and CV mortality. The femoral artery calcification also can predict the mortality, but the calcification of iliac artery, radial artery, and finger arteries cannot predict the mortality of PD patients.

Abstract
AIM Several studies have verified that unfractionated heparin (UFH) and low molecular heparin (LWMH) can induce bone loss, and bone mineral density has been inversely associated with vascular calcification in some clinical researches. But few have focused on the relationship between types and dosages of heparin and the progression of vascular calcification. We observed the progression of coronary artery calcification (CAC) in maintenance haemodialysis (MHD) patients who were treated with UFH and LMWH. METHODS This was a prospective prevalent cohort study of MHD patients. Computed tomography was performed at enrolment and 2 years after enrolment, and CAC score was obtained. Demographic and clinical data, baseline and time-average laboratory indices were collected. Multiple linear regression and logistic regression were used to estimate the influencing factors of progression of CAC. RESULTS In this study, (i) we initially enrolled 69 HD patients, and then 56 patients finished the follow-up. (ii) Among the total 56 patients, 27 patients (48.2%) were treated with UFH, 14 (25.0%) with LMWH and 15 (26.8%) with both. The median baseline CAC scores of three groups (UFH, LMWH and both users) were 91.0 (1.0, 1052.0), 134.0 (0, 1292.0) and 250.5 (27.0, 1139.0), respectively, with no significant difference (P = 0.663); the median CAC progression scores were 42.0 (0, 364.0), 172.0 (7.0, 653.0) and 118.5 (0, 434.0), respectively, with no significant difference (P = 0.660). (iii) Pearson and spearman correlation analysis shown that the progression of CAC was not associated with cumulative dosage of heparin used. (iv) After adjusted for diabetes mellitus, time-averaged intact parathyroid hormone, phosphate and alkaline phosphatase, logistic regression analysis showed using different types of heparin was not an independent risk factor for CAC progression; and multiple linear regression analysis showed that the type of heparin used was not associated with CAC progression. CONCLUSION There were no significant differences in the effects of the types and dosages of heparin on CAC progression in patients on haemodialysis.

Abstract
All fields of industry are applying nanotechnologies for the development of advanced materials, there¬fore at present the number of workers exposed to nanosized materials are significantly increasing. Unfortunately, protective equipment for nanoparticles (NPs) is of uncertain efficacy so the risk of noxious effects, in particular allergic sensitization, on workers gives many concerns. At the same time, studies of allergic physiopathology demonstrated that the lack of prevention and treatment could result in invalidating dis¬eases that, in case of professional etiology, might imply removal from the job and compensation. Therefore, a deeper knowledge of the role of NPs in inducing allergic diseases is mandatory to implement the risk assessment and preventive measures for nanosafety in the workplace. The possibility that NPs favor, ex¬acerbate or directly induce allergy is being suggested by recent experimental investigations in cellular and animal models. Unfortunately, studies are heterogeneous and few data have received experimental confir¬mation, lacking reproducibility. What comes to attention is the uncertainty about the real plausibility of the observed experimental effects, as there are only a few reported cases of allergy onset or exacerbation for workers exposed to NPs. However, the potential for NPs to induce, favor or exacerbate allergies seems possible even though not completely demonstrated. This should be a greater incentive to carry out appro¬priate epidemiological studies that are lacking and really needed.

Abstract
OBJECTIVE To investigate the occurrence of vascular calcification (VC) in different types of arteries in patients with maintenance peritoneal dialysis (PD) patients and its influencing factors. METHODS This study enrolled PD patients with stable status who has received PD treatment for more than 6 months in Peking University People's Hospital. We used plain X-ray films of abdomen, pelvis, and hands to quantitatively evaluate VC of large artery (abdominal aorta, iliac artery), medium artery (femoral artery, radial artery), and small artery (finger arteries). Two radiologists read and scored radiographs blindly. Demographic data, clinical characteristics, Charlson comorbidity index (CCI), baseline and time-average laboratory indices including parameters of calcium phosphorus metabolism, serum albumin, PD adequacy were collected. A logistic regression model was used to estimate the influencing factors of different sites of VC. RESULTS (1) 154 PD patients were enrolled in this study: seventy-eight males, mean age was 60.4 ± 13.9 years, and median PD duration was 24 (16.39) months. The major primary disease was diabetic nephropathy (39%). (2) Among the 154 PD patients, the proportion of calcification of large artery was the highest (found in 100 patients, accounting for 64.9%); then the medium artery (66, 42.9%); and 15 of small artery, accounting for 9.7%. (3) Logistic regression showed that older age, longer dialysis duration, lower baseline serum intact parathyroid hormone (iPTH), and higher CCI scores were independent risk factors of large artery calcification (p < 0.05), and higher CCI scores, higher baseline serum triglycerides (TG), lower baseline serum iPTH, and time-average iPTH were independent risk factors of medium and small arteries. CONCLUSIONS In PD patients, the occurrence of large artery calcification was higher than others. Among different sites of VC, the abdominal aortic calcification was most likely to occur, and the proportion of small artery calcification was low. Calcification of medium and small arteries can exist alone without calcification of large artery. Large artery calcification was more likely to occur in patients with older age, longer dialysis duration, lower baseline serum iPTH levels and higher CCI scores. Patients with higher CCI scores, higher baseline TG and lower baseline iPTH, and time-average iPTH were more likely to develop small and medium artery calcification.

Abstract
Peritonitis is the most common complication in patients undergoing peritoneal dialysis (PD). Peritoneal dialysis-related peritonitis caused by Brucella species has been reported in only 7 patients before. Here, we report a further case of Brucella peritonitis. This patient was successfully treated with both intraperitoneal and prolonged oral antibiotics, without removal of the PD catheter. We review relevant literature and make recommendations for the diagnosis and treatment of Brucella PD-related peritonitis from the cumulative published clinical experience.

BACKGROUND Abdominal aortic calcification (AAC) has a pretty high incidence in dialysis patients and may be associated with their prognosis. AAC can be assessed by abdominal CT or X-ray. We determined to investigate whether the occurrence of AAC is associated with all-cause mortality and cardiovascular (CV) events in dialysis patients through this meta-analysis and systematic review. METHODS A comprehensive literature search was conducted using the PubMed, Cochrane library, Embase, Medline databases to collect cohort studies investigating whether AAC is associated with all-cause mortality and CV events of patients, and we also searched gray articles and conferences abstracts. Meta-analysis was performed by STATA software. Pooled results were expressed as hazard ratio (HR) with corresponding 95% confidence intervals (CI). Fixed-effect models were used to pool the HR of each trial. RESULTS 10 studies (2,724 dialysis patients) were identified. The presence of AAC was associated with increased risk for all-cause mortality among dialysis patients (HR, 2.84; 95% CI, 2.03-3.98; I2 = 9.8%; P = 0.354). Meanwhile, there was an association between AAC and increased risk for all CV events (fatal and non-fatal) in patients (HR, 2.04; 95% CI, 1.51-2.76, I2 = 44.6%; P = 0.125). 3 studies presented their endpoint as CV mortality, and the pooled HR was 2.46 (95%CI 1.38-4.40; I2 = 0.0%; P = 0.952). There were also 2 studies that reported their primary endpoint as all-cause mortality and CV events, and the pooled HR was 5.72 (95% CI 3.24-10.10; I2 = 0.0%; P = 0.453). CONCLUSIONS Among patients treated with dialysis, AAC is associated with adverse outcomes, including all-cause mortality and CV events (fatal and non-fatal). The abdominal X-ray or CT scan can be used as a useful added method to evaluate the patient's calcification. This may provide reasonable data for estimating the risk of adverse events in dialysis patients, which is helpful in guiding clinical treatment and improving the prognosis of dialysis patients.

Abstract
A fundamental issue concerning iron-based superconductivity is the roles of electronic nematicity and magnetism in realising high transition temperature (T c). To address this issue, FeSe is a key material, as it exhibits a unique pressure phase diagram involving non-magnetic nematic and pressure-induced antiferromagnetic ordered phases. However, as these two phases in FeSe have considerable overlap, how each order affects superconductivity remains perplexing. Here we construct the three-dimensional electronic phase diagram, temperature (T) against pressure (P) and isovalent S-substitution (x), for FeSe1-x S x . By simultaneously tuning chemical and physical pressures, against which the chalcogen height shows a contrasting variation, we achieve a complete separation of nematic and antiferromagnetic phases. In between, an extended non-magnetic tetragonal phase emerges, where T c shows a striking enhancement. The completed phase diagram uncovers that high-T c superconductivity lies near both ends of the dome-shaped antiferromagnetic phase, whereas T c remains low near the nematic critical point.

Abstract
In conventional metals, modification of electron trajectories under magnetic field gives rise to a magnetoresistance that varies quadratically at low field, followed by a saturation at high field for closed orbits on the Fermi surface. Deviations from the conventional behaviour, for example, the observation of a linear magnetoresistance, or a non-saturating magnetoresistance, have been attributed to exotic electron scattering mechanisms. Recently, linear magnetoresistance has been observed in many Dirac materials, in which the electron–electron correlation is relatively weak. The strongly correlated helimagnet CrAs undergoes a quantum phase transition to a nonmagnetic superconductor under pressure. Here we observe, near the magnetic instability, a large and non-saturating quasilinear magnetoresistance from the upper critical field to 14 T at low temperatures. We show that the quasilinear magnetoresistance may arise from an intricate interplay between a nontrivial band crossing protected by nonsymmorphic crystal symmetry and strong magnetic fluctuations. The electronic structure of the helimagnet CrAs is unusual due to its nonsymmorphic crystal symmetry. Here, the authors observe quasilinear magnetoresistance close to a pressure-driven superconducting transition, which may arise from the interaction of the band structure and magnetic fluctuations.

Abstract
Objective: To study the effects of subchronic aluminum exposure on LTP and activities of RAS and ERK in rats in vivo. Methods: 24 Wistar rats were randomly divided into control group、low-dose group、medium-dose group and high-dose group, and received saline (control group) or Al (mal) (3) (15 μmol、kg、30 μmol、kg or 45 μmol/kg) via intraperitoneal injection (i.p.) for 8 weeks, respectively. The fEPSP in CA1 region were recorded by field potentiation technique in vivo and the hippocampal activities of RAS and ERK were examined by ELISA. Results: The fEPSP amplitudes of the control group were 1.90±0.19, 1.64±0.15 and 1.54±0.08 at 1, 30 and 60 min after HFS, respectively. The fEPSP amplitudes of the low-dose group were 1.40±0.06 at 60 min, which represented a statistically significant decrease compared to the control group (P<0.05) ; these values at 30min and 60min dropped to 1.33±0.20 and 1.12±0.07 in the medium-dose group (P<0.05) and further decreased to 1.05±0.05 and 0.91±0.10 in the high-dose group (P<0.05) . And the activity dose-dependent decreases were observed both in RAS and ERK: compared with the control group and the low-dose group, the activities of RAS and ERK of the medium-dose and high-dose group significantly decreased (P<0.05) and compared with the medium-dose group, the activities of the high-dose group statistically dropped (P<0.05) . Conclusion: RAS and ERK may be related to the suppression of LTP by subchronic aluminum exposure and the RAS-MAPK transduction pathway may be involved in the damage of learning and memory induced by aluminum.

Abstract
OBJECTIVE To investigate the association between serum aluminium level and methylation of the promoter region of amyloid precursor protein (APP)gene in workers engaged in aluminium electrolysis. METHODS In 2012, 366 electrolysis workers in an aluminium factory were enrolled as exposure group (working years >10 and age >40 years)and divided into low-exposure group and high-exposure group based on the median serum aluminium level. Meanwhile, 102 workers in a cement plant not exposed to aluminium were enrolled as control group. Graphite furnace atomic absorption spectrometry was used to measure serum aluminium level, methylation specific PCR was used to measure the methylation rate of the promoter region of APP gene, and ELI-SA was used to measure the protein expression of APP in lymphocytes in peripheral blood. RESULTS The exposure group had a significantly higher serum aluminium level than the control group (45.07 μg/L vs 30.51 μg/L, P< 0.01). The exposure group had a significantly lower methylation rate of the promoter region of APP gene than the control group (18.85% vs 25.49%, P=0.025), and the high-exposure group had a significantly lower methylation rate of the promoter region of APP gene than the low-exposure group (15.84% vs 21.85%, P<0.05). The exposure group had a significantly higher protein expression of APP in lymphocytes in peripheral blood than the control group (66.73 ng/ml vs 54.17 ng/ml, P<0.05); compared with the low-exposure group (65.39 ng/ml), the high-exposure group showed an increase in the protein expression of APP in lymphocytes in peripheral blood (67.22 ng/ml), but there was no significant difference between these two groups (P>0.05). The multivariate logistic regression analysis showed that with reference to the control group, low aluminium exposure (OR=1.86, 95% CI 1.67~3.52)and high aluminium exposure (OR=2.98, 95% CI 1.97~4.15)were risk factors for a reduced methylation rate of the promoter region of APP gene. CONCLUSION Reduced methylation of the promoter region of APP gene may be associated with increased serum aluminium level, and downregulated methylation of the promoter region of APP gene may accelerate APP gene transcription.

Methods: The embryos of zebrafishat 6 hours after fertilization were exposed to AlCl(3) solution at a concentration of 0, 55.0, 60.5, 66.6, 73.5, 80.5, or 100.0 mg/L, and embryonic hatching rates at 48 and 72 hours after fertilization were calculated. The embryos of zebrafishat 6 hours after fertilization were exposed to AlCl(3) solution at a concentration of 0, 60.0, 72.0, 86.4, 103.7, or 124.4 mg/L, and the embryonic mortality rates at 12, 24, 48, 72, and 96 hours after fertilization were calculat-ed. The embryos of zebrafish at 6 hours after fertilization were exposed to AlCl(3) solution at a concentration of 0, 50, 100, 200, 400, or 800 μg/L, and the changes in the neurobehavior of juvenile fish were observed after hatching, including touch-escape reaction at 72 hours after fertilization and autonomic movement and panic es-cape reflex at 7 days after fertilization. Results: Compared with the 0 mg/L group, the≥66.6 mg/L group had a sig-nificant reduction in embryonic hatching rate at 48 and 72 hours after fertilization, and the ≥72.0 mg/L group had a significant increase in embryonic mortality rate at 96 hours after fertilization (P<0.05) . Compared with the 0 μg/L group, the≥100 μg/L group had a significant reduction in the number of times of touch-escape reaction (P<0.05) .Compared with the 0 and 50 μg/L groups, the 100-800 μg/L groups had significant reductions in total movement distance and average speed (P<0.05) . Compared with the dark period before illumination, all groups had a significant increase in movement speed during the light period of the panic escape reflex test (i.e., the third minute) (P<0.05) ; within 2 minutes after the light was turned off, there was no significant change in movement speed in the 0-200 μg/L groups (P>0.05) ; the 400 and 800 μg/L groups had a significant increase in movement speed (P<0.05) . Conclusion: AlCl(3) exposure may cause embryonic developmental disorder in zebrafish and ab-normal neurobehavior in juvenile fish.

Abstract
Objective: To investigate the influence of occupational aluminum exposure on cognitive function and glutamate receptor protein expression in peripheral blood lymphocytes in workers and the possibility of glutamate receptor being used as a biomarker for cognitive impairment in aluminum workers. Methods: From October to December, 2014, cluster sampling was performed to select 121 workers in aluminum electrolysis workshop as exposure group and 231 workers in thermoelectric workshop and logistics department as control group. Mini-Mental State Examination, clock drawing test, digit span test (DST) , verbal fluency test (VFT) , and Fuld Object-Memory (FOM) Evaluation were used to analyze cognitive function. Graphite furnace atomic absorption spectrophotometry was used to measure plasma aluminum level as an exposure indicator. Enzyme-linked immunosorbent assay was used to measure the content of glutamate receptor proteins in peripheral blood lymphocytes, including the subunits of N-methyl-D-aspartate receptor NR1, NR2A, and NR2B and metabotropic glutamate receptor 1 (mGluR1) . The correlation between cognitive function indices and the content of glutamate receptor proteins was analyzed. Results: There was no significant difference in plasma aluminum level between the control group and the exposure group (132.52±80.40 μg/L vs 182.88±72.32 μg/L, P>0.05) . According to the plasma aluminum level, the study subjects were divided into control group and low-, medium-, and high-level plasma aluminum groups, and there were significant differences in plasma aluminum level between these groups (all P<0.01) . The high-level plasma aluminum group had a significantly lower memory ability score than the control group and the low- and medium-level plasma aluminum groups (all P<0.05) . The high-level plasma aluminum group had lower DST and digital span forward (DSF) scores than the control group and the low-and medium-level plasma aluminum groups. The low-, medium-, and high-level plasma aluminum groups had lower digital span backward (DSB) scores than the control group. The medium-and high-level plasma aluminum groups had lower VFT scores than the control group and the low-level plasma aluminum group. The high-level plasma aluminum group had significantly lower expression of NR1 and NR2A proteins than the control group and the low-and medium-level plasma aluminum groups, and the medium- and high-level plasma aluminum groups had significantly higher expression of mGluR1 protein than the control group and the low-level plasma aluminum group (all P<0.05) . The expression of NR1 and NR2A proteins was negatively correlated with plasma aluminum level (r=-0.475 and -0.692, both P<0.05) , andthe expression of mGluR1 protein was positively correlated with plasma aluminum level (r=0.756, P<0.05) . The expression of NR1 protein was positively correlated with DSF, DSB, DST, and VFT scores (r(s)=0.213, 0.249, 0.271, and 0.228, all P<0.05) , and the expression of NR2A protein was positively correlated with VFT score (r(s)=0.206, P<0.05) . Conclusion: Occupational aluminum exposure may affect workers' memory function, and the expression of NR1 and NR2A in peripheral blood lymphocytes is correlated with cognitive function indices and can be used as biomarkers for cognitive impairment in aluminum workers.

Abstract
Deep sea fish oil mainly includes polyunsaturated fatty acid, which is usually used as health products and applied for prevention of cardiovascular and cerebrovascular diseases. However, there are only a few studies investigating the diabetes induced nerve injury till now. We established the diabetic model by using the 8-week old inbred male mice, and assumed that fish oil had a certain therapeutic effect on related neurosensory impairment and oxidative stress. Mice were divided into group A (diabetic mice induced by streptozotocin (STZ) and treated with fish oil), group B (diabetic mice) and group C (normal mice, without STZ treatment). The memory and exploration ability were evaluated and oxidation status of brain tissue was detected. Results indicated that memory and exploration ability of fish oil group A was significantly improved compared to diabetic group B (P<0.05), and equal to group C. The malondialdehyde (MDA) level of fish oil group A was decreased significantly and antioxidant level was increased significantly compared to diabetic group B (P<0.05), and equal to group C. In conclusion, deep sea fish oil could be used as auxiliary health care products, which plays important role in preventing and treating implications of nerve lesion impairment induced by diabetes mellitus.

Abstract
Objective: To investigate the influence of occupational aluminum exposure on cognitive function and its relationship with tri-methyl histone H3 lysine residues 4 points (H3K4me3) and brain-derived neurotrophic factor (BDNF) levels. Methods: By cluster random sampling method, a total of 235 cases of male workers selected from a Shanxi aluminum factory were recruited in the study in September 2015. Used the occupational epidemiological investigation questionnaire, which included Mini-Mental State Examination (MMSE) , Clock Drawing Test (CDT) , Digit Span Test (DST, including forward test DSFT and backward test DSBT) , Fuild Object Memory Evaluation (FOME) and Verbal Fluency Test (VFT) , to collect workers' basic information and assess their cognitive function score. Detected the concentration of aluminum in plasma by graphite furnace atomic absorption spectrometry. Workers were divided into three groups by the 25 percentile and 75 percentile of the aluminum content, such as low, middle and high aluminum concentration groups. The concentrations of H3K4me3 in lymphocyte and BDNF in plasma were determined by enzyme-linked immunosorbent assay. Results: The levels of aluminum in plasma was 134.36 (100.14, 178.96) μg/L. The scores of MMSE, DSFT, DSBT, DST of high aluminum concentration group were lower than low aluminum group (27.98±1.25 vs 28.83±1.54, 9.19±2.00 vs 10.64±2.87, 6.08±1.63 vs 7.19±3.07, 15.27±3.11 vs 17.81±4.72, all P<0.05) , the scores of CDT, FOME, VFT among three groups had no statistical significance (all P>0.05) . The expression levels of H3K4me3 and BDNF of high aluminum concentration group were lower than the low group [ (18.45±9.81) ng/μg Pro vs (23.76±9.89) ng/μg Pro, (26.07±10.18) ng/ml vs (31.66±9.24) ng/ml, all P<0.05]. Multiple correlation analysis showed that aluminum concentration were negatively correlated toH3K4me3, BDNF, MMSE, DSFT, DST, respectively (r(s)=-0.307、-0.214、-0.252、-0.197, -0.181, all P<0.01) . Conclusion: Exposure to occupational aluminum for a long time may change cognitive function, which go along with the decreasing of H3K4me3 level in lymphocyte and BDNF protein expression in plasma.

Abstract
Objective: This study aimed to estimate the prevalence of dyslipidemia, hypertriglyceridemia, hypercholesterolemia, high blood low density lipoprotein cholesterol (LDL-C), and low blood high density lipoprotein cholesterol (HDL-C) in remote rural areas of Xinjiang and analyze these indicators' epidemiological characteristics. Methods: A survey of 13 000 individuals (aged ≥18 years) was conducted using a four-stage cluster random sampling method in Jiashi, Xinyuan, Aheqi, and Shawan Counties, Xinjiang, in 2009-2010. After nonpermanent residents were excluded, 12 154 individuals were included in this study. Questionnaire and physical examinations were conducted, including collection of fasting blood to detect TG, TC, LDL-C, and HDL-C. The results were calculated after complex weighting and compared according to the prevalence of different gender and age groups. Results: The overall levels of TG, TC, LDL-C, and HDL-C were 1.34±1.09, 4.45±1.16, 2.36±0.86, and 1.37±0.58 mmol/L, respectively. After complex weighting, the overall prevalence of dyslipidemia was 35.4%; that among men (42.9%) was greater than that among women (29.5%; χ2=234.19, P<0.001), and the prevalence was 35.9%, 34.5%, and 35.1% (χ2=1.52, P=0.467) in participants aged 18-44, 45-59, and ≥60 years, respectively. The overall prevalence of hypertriglyceridemia was 11.4%; that among men (13.5%) was greater than that among women (9.8%; χ2= 40.72, P<0.001), and the prevalence was 9.6%, 13.0%, and 13.2% (χ2=38.71, P<0.001) in participants aged 18-44, 45-59, and ≥60 years, respectively. The prevalence of hypercholesterolemia was 5.7%; that among men(5.0%) was greater than that among women (6.2%; χ2=6.95, P=0.008), and the prevalence was 3.5%, 7.4%, and 8.4% (χ2=105.24, P<0.001) in participants aged 18-4, 45-59, and ≥60 years, respectively. The prevalence of high blood LDL-C was 2.8%, and there was no significant difference between men (3.0%) and women (2.4%; χ2=1.43, P=0.231); the prevalence was 3.5%, 7.4%, and 8.4% (χ2=42.81, P<0.001) in participants aged 18-44, 45-59, and ≥60 years, respectively. The prevalence of low blood HDL-C was 24.0%; that among men (31.6%) was greater than that among women (18.0%; χ2=304.02, P<0.001), and the prevalence was 27.8%, 20.6% and 19.5% (χ2=96.61, P<0.001) in participants aged 18-44, 45-59, and ≥ 60 years, respectively. Conclusions: Low blood HDL-C was the main type of dyslipidemia among the population in remote rural areas of Xinjiang. The prevalence of dyslipidemia among men was greater than that among women, and there was a trend of younger men than women showing dyslipidemia.

Abstract
OBJECTIVE To explore the relationship between the polymorphisms and haplotypes in the CETP gene and dyslipidemia among Xinjiang Kazak and Uygur residents. METHODS A population status survey was performed from 2010 to 2011 in Kashgar Xinjiang Uygur and Kazak residents, stratified cluster sampling method was used to select Uygur, Kazak residents with abnormal blood lipid values (n=367 and 345, respectively) as the dyslipidemia groups, and to select residents with normal lipid values as control group from the same area (n=374 and 390, respectively). SNaPshot technology was applied to detect the DNA of CETP gene rs3764261, rs1800775, rs708272 and rs5882 loci in all selected residents, and linkage disequilibrium analysis and haplotype construction were performed. RESULTS (1) In Uygur residents, the dyslipidemia risk of rs708272 CT (OR=0.64, 95%CI 0.46-0.91, P=0.01) and TT genotype (OR=0.60, 95%CI 0.40-0.91, P=0.02) was significantly lower than CC genotype. Dyslipidemia risk of rs3764261 GT (OR=0.55, 95%CI 0.40-0.74, P=0.00) and TT genotype (OR=0.47, 95%CI 0.28-0.78, P<0.01) was significantly lower than GG genetype. Dyslipidemia risk of the rs1800775 CC genotype was higher than AA genotype (OR=1.79, 95%CI 1.17-2.74, P=0.01). There was no statistical significance in CETP gene of the 4 genotype and allele frequency between the dyslipidemia and normal lipid groups in Kazak residents (all P>0.05). (2) In Uighur residents with dyslipidemia, HDL-C level was significantly higher in rs708272 TT genotype carriers than in CC and CT genotypes (all P<0.05) and in rs3764261 TT genotype carriers than in GG genotype carriers (P=0.008), while was significantly lower in rs1800775 CC genotype carriers with AA genotype carriers (P=0.008). (3) Linkage disequilibrium analysis showed that there was strong linkage disequilibrium between rs3764261 and rs708272 (D'=0.869, r(2)=0.869), rs1800775 and rs708272 (D'=0.845, r(2)=0.446) in Uighur residents, and there was strong linkage disequilibrium between rs3764261 and rs708272 (D'=0.963, r(2)=0.963), rs1800775 and rs708272 (D'=0.988, r(2)=0.630) in Kazak residents. (4) Significant differences were observed in frequency distribution of haplotype GACA(OR=0.579, 95%CI 0.388-0.864, P=0.006), GATA (OR=2.183, 95%CI 1.231-3.873, P=0.006), GCCA (OR=0.723, 95%CI 0.549-0.954, P=0.001), TATA (OR=0.723, 95%CI 0.549-0.954, P=0.021) and TATG (OR=0.601, 95%CI 0.429-0.841, P=0.002) in Uighur residents with normal or abnormal lipid profiles, while significant difference was observed in frequency distribution of haplotype GCCG (OR=1.961, 95%CI 1.207-3.188, P=0.005) in Kazak residents with normal or abnormal lipid profiles. CONCLUSION CETP genotype rs708272, rs3764261 and rs1800775 polymorphism is closely related to dyslipidemia and haplotype GACA, TATA and TATG will reduce the risk of dyslipidemia, while haplotype GATA, GCCA will increase the risk of dyslipidemia in Uygur residents. The four CETP polymorphisms are not related to the risk of dyslipidemia, but haplotype GCCG is related to increased risk of dyslipidemia in Kazakhs residents.
