Abstract
Skin hyperpigmentation is a worldwide condition associated with augmented melanogenesis. However, conventional therapies often entail various adverse effects. Here, we explore the safety range and depigmentary effects of polysaccharides extract of Tricholoma matsutake (PETM) in an in vitro model and further evaluated its efficacy at the clinical level. An induced-melanogenesis model was established by treating B16-F10 melanoma cells with 8-methoxypsoralen (8-MOP). Effects of PETM on cell viability and melanin content were examined and compared to a commonly used depigmentary agent, α-arbutin. Expressions of key melanogenic factors and upstream signaling pathway were analysed by quantitative PCR and western blot. Moreover, a placebo-controlled clinical study involving Chinese females with skin hyperpigmentation was conducted to measure the efficacy of PETM on improving facial pigmented spots, melanin index, and individual typology angle (ITA°). Results demonstrated that PETM (up to 0.5 mg/mL) had little effect on the viability and motility of B16-F10 cells. Notably, it significantly suppressed the melanin content and expressions of key melanogenic factors induced by 8-MOP in B16-F10 melanoma cells. Western blotting results revealed that PETM inhibited melanogenesis by inactivating c-Jun N-terminal kinase (JNK), and this inhibitory role could be rescued by JNK agonist treatment. Clinical findings showed that PETM treatment resulted in a significant reduction of facial hyperpigmented spot, decreased melanin index, and improved ITA° value compared to the placebo-control group. In conclusion, these in vitro and clinical evidence demonstrated the safety and depigmentary efficacy of PETM, a novel polysaccharide agent. The distinct mechanism of action of PETM on melanogenic signaling pathway positions it as a promising agent for developing alternative therapies.

Abstract
BACKGROUND Treatment options for T1/2N0M0 anal squamous cell carcinoma include chemotherapy, radiotherapy, chemoradiotherapy, and local excision, although the optimal treatment method has not been determined. METHODS The National Cancer Institute Surveillance, Epidemiology and Results database was used to search and screen 1465 patients with cT1/2N0M0 anal squamous cell carcinoma who were clinically diagnosed between 2004 and 2016. Survival analysis was performed using the Kaplan-Meier method and log-rank test. Cox proportional hazards regression analysis was performed to screen independent prognostic factors and build a nomogram survival prediction model. According to the risk score, patients were divided into low, medium, and high risk groups using X-tile software. RESULTS Age, sex, grade and cT stage were identified as independent prognostic factors for cT1/2N0M0 anal squamous cell carcinoma and were included in the nomogram to construct a prediction model. The C-index of the model was 0.770 [95% confidence interval (CI), 0.693-0.856], which was higher than the C-index of T stage 0.565 (95% CI, 0.550-0.612). Low-risk patients benefited from local resection, moderate-risk patients benefited from radiotherapy, and high-risk patients benefited from radiotherapy or chemoradiotherapy. This was confirmed using external validation data from the center. CONCLUSION The nomogram developed in this study effectively and comprehensively evaluated the prognosis of patients with cT1/2N0M0 squamous cell carcinoma of the anal canal. Local excision is recommended for low risk patients, radiotherapy for moderate-risk patients, and radiotherapy or chemoradiotherapy for high-risk patients.

Abstract
PURPOSE Despite advancements in laparoscopic ventral hernia repair (LVHR) using the intraperitoneal onlay mesh technique (sIPOM), recurrence remains a common postoperative complication. The objective of this systematic review and meta-analysis is to compare the efficacy of defect closure (IPOM-plus) versus non-closure in ventral and incisional hernia repair. The aim is to determine which technique yields better outcomes in terms of reducing recurrence and complication rates. METHODS A comprehensive literature review was conducted in the PubMed, Web of Science, Cochrane Library, Embase, and ClinicalTrials.gov databases from their inception until October 1, 2022, to identify all online English publications that compared the outcomes of laparoscopic ventral hernia repair with and without fascia closure. RESULTS Three randomized controlled trials (RCTs) and eleven cohort studies involving 1585 patients met the inclusion criteria. The IPOM-plus technique was found to reduce the recurrence of hernias (OR = 0.51, 95% CI [0.35, 0.76], p < 0.01), seroma (OR = 0.48, 95% CI [0.32, 0.71], p < 0.01), and mesh bulging (OR = 0.08, 95% CI [0.01, 0.42], p < 0.01). Subgroup analysis revealed that body mass index (BMI) (OR = 0.43, 95% CI [0.29, 0.65], p < 0.0001), type of article (OR = 0.51, 95% CI [0.35, 0.76], p = 0.0008 < 0.01), geographical location (OR = 0.54, 95% CI [0.36, 0.82], p = 0.004 < 0.01), follow-up time (OR = 0.50, 95% CI [0.34, 0.73], p = 0.0004 < 0.01) had a significant influence on the postoperative recurrence of the IPOM-plus technique. CONCLUSION The IPOM-plus technique has been shown to greatly reduce the occurrence of recurrence, seroma, and mesh bulging. Overall, the IPOM-plus technique is considered a safe and effective procedure. However, additional randomized controlled studies with extended follow-up periods are necessary to further evaluate the IPOM-plus technique.

Abstract
Tributyltin (TBT) can be used as an antifouling agent with anticorrosive, antiseptic and antifungal properties and is widely used in wood preservation and ship painting. However, it has recently been found that TBT can be harmful to aquatic organisms. In this study, to gain insight into the effects of TBT with respect to the development of the cardiovascular system in zebrafish embryos, zebrafish embryos were exposed to different concentrations of TBT solutions (0.2 μg/L, 1 μg/L, and 2 μg/L) at 2 h post-fertilization (hpf) TBT exposure resulted in decreased hatchability and heart rate, deformed features such as pericardial edema, yolk sac edema, and spinal curvature in zebrafish embryos, and impaired heart development. Expression of cardiac development-related genes (vmhc, myh6, nkx2.5, tbx5a, gata4, tbx2b, nppa) is dysregulated. Transgenic zebrafish Tg (fli1: EGFP) were used to explore the effects of TBT exposure on vascular development. It was found that TBT exposure could lead to impaired development of intersegmental vessels (ISVs), common cardinal vein (CCV), subintestinal vessels (SIVs) and cerebrovascular. The expression of vascular endothelial growth factor (VEGF) signaling pathway-related genes (flt1, flt4, kdr, vegfa) was downregulated. Biochemical indices showed that ROS and MDA levels were significantly elevated and that SOD and CAT activities were significantly reduced. The expression of key genes for prostacyclin synthesis (pla2, ptgs2a, ptgs2b, ptgis, ptgs1) is abnormal. Therefore, it is possible that oxidative stress induced by TBT exposure leads to the blockage of arachidonic acid (AA) production in zebrafish embryos, which affects prostacyclin synthesis and consequently the normal development of the heart and blood vessels in zebrafish embryos.

Abstract
Acne vulgaris represents a chronic inflammatory condition, the pathogenesis of which is closely associated with the altered skin microbiome. Recent studies have implicated a profound role of Gram-negative bacteria in acne development, but there is a lack of antiacne agents targeting these bacteria. Polyphyllins are major components of Rhizoma Paridis with great anti-inflammatory potential. In this study, we aimed to evaluate the antiacne effects and the underlying mechanisms of PPH and a PPH-enriched Rhizoma Paridis extract (RPE) in treating the Gram-negative bacteria-induced acne. PPH and RPE treatments significantly suppressed the mRNA and protein expressions of interleukin (IL)-1β and IL-6 in lipopolysaccharide (LPS)-induced RAW 264.7 and HaCaT cells, along with the intracellular reactive oxygen species (ROS) generation. Furthermore, PPH and RPE inhibited the nuclear translocation of nuclear factor kappa-B (NF-κB) P65 in LPS-induced RAW 264.7 cells. Based on molecular docking, PPH could bind to kelch-like ECH-associated protein 1 (KEAP1) protein. PPH and RPE treatments could activate nuclear factor erythroid 2-related factor 2 (NRF2) and upregulate haem oxygenase-1 (HO-1). Moreover, RPE suppressed the mitogen-activated protein kinase (MAPK) pathway. Therefore, PPH-enriched RPE showed anti-inflammatory and antioxidative effects in vitro, which is promising for alternative antiacne therapeutic.

Abstract
AIM To explore the feasibility of a "triple-low" dose (low tube voltage, low tube current, and low contrast agent volume) bronchial artery computed tomography (CT) angiography (CTA) to replace routine dose bronchial artery CTA before bronchial artery embolisation (BAE). MATERIALS AND METHODS CTA was obtained from 60 patients with body mass index (BMI) < 30 kg/m2 using a 256 multi-section iCT system, and they were divided into two groups: (1) group A: 100 kVp, 100 mAs, 50 ml contrast medium (CM); (2) group B: 120 kVp, automatic tube current modulation (ACTM), 80 ml CM. CT attenuation of the thoracic aorta, image noise, signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were calculated, and subjective image quality scores and traceability scores assessed. The effective radiation dose was calculated. RESULTS The radiation dose was reduced by 79.7% in group A compared to group B (p<0.05). The CT attenuation of the thoracic aorta was increased by approximately 13% in group A compared to group B (p<0.05). Higher image noise, lower SNR, and CNR were obtained in group A compared to group B (all p<0.05). Both subjective image quality scores and traceability scores did not differ between groups A and B (both p>0.05). CONCLUSION It is feasible to use the "triple-low" dose CTA protocol for patients with a body mass index (BMI) < 30 kg/m2. The radiation dose was reduced by 79.7%, and the dose of contrast medium was reduced by 37.5% to ensure the diagnostic value.

Abstract
BACKGROUND To retrospectively analyze the rescue of medical emergencies and critical patients in the oral emergency department in a hospital during the past 14 years; analyze the general condition of patients, their diagnosis, etiological factors, and outcomes of the disease, so as to improve the ability of oral medical staff to deal with emergencies; and optimize the emergency procedures and resource allocation in such departments. MATERIAL AND METHODS Data and related information of critical patient emergency rescue from the Emergency Department of the Hospital of Stomatology, Peking University from January 2006 to December 2019, were analyzed. RESULTS A total of 53 critical patients were rescued in the oral emergency department in the past 14 years, which is an average of four cases per year, with an incidence rate of 0.00506%. The main type of emergency included hemorrhagic shock and active hemorrhage, with the highest incidence being in the age group of 19-40 years old. Among these cases, 67.92% (36/53) developed emergency and critical diseases before visiting the oral emergency department and 41.51% (22/53) had systemic diseases. After rescue, a total of 48 patients (90.57%) had stable vital signs and 5 (9.43%) died. CONCLUSIONS Oral doctors and other medical staff should be able to rapidly identify medical emergencies in oral emergency departments and commence emergency treatment. The department should be equipped with relevant first-aid drugs and devices, and medical staff should be regularly trained in practical first-aid skills. Patients with oral and maxillofacial trauma, massive hemorrhage and systemic diseases should be evaluated and treated according to their conditions and systemic organ function to prevent and reduce medical emergencies.

Abstract
AIM To evaluate the feasibility of standard uptake value (SUV) index (ratio lesional maximum SUV [SUVmax] to liver mean SUV [SUVmean]) as a metabolic parameter for diagnosing polymyalgia rheumatica (PMR). MATERIALS AND METHODS A retrospective group of patients with PMR and controls with symptoms similar to PMR but diagnosed with other diseases. Semiquantitative and qualitative analysis of 2-[18F]-fluoro-2-deoxy-d-glucose (18F-FDG) uptake at 18 sites was undertaken for all patients. The diagnostic value of positron-emission tomography/computed tomography (PET/CT) for PMR was assessed by R software using logistic regression and a generalised additive model (GAM). All images were examined independently by two nuclear medicine physicians with extensive work experience. RESULTS The characteristic sites of PMR were the ischial tuberosity, interspinous bursa, periarticular hip, and symphysis pubis enthesis. The area under the curve (AUC) of the characteristic site SUV index was 0.930, and the best cut-off value was 1.685 with a sensitivity of 84.6% and a specificity of 92.6%. After adjusting for potential confounders, the probability of PMR diagnosis increased as the characteristic site SUV index increased and there was a nonlinear correlation between the two. When the characteristic site SUV index was ≥2.56, the probability of PMR gradually reached the threshold effect, which was as high as 90% or more. CONCLUSION The characteristic site SUV index is an independent factor for diagnosing PMR, and PMR should be highly suspected when it is ≥ 1.685. Nonetheless, it is important to note that these findings are based on an initial retrospective single-centre study and require external validation and further prospective evaluation before being translated into clinical practice.

Abstract
BACKGROUND Chronic kidney disease (CKD) is a serious public health issue worldwide, but the disease burden of CKD caused by different etiologies and changing trends has not been fully examined. METHODS We collected data from Global Burden of Disease Study 2019 (GBD 2019), including incident cases, age-standardized incidence rate (ASIR), disability-adjusted life years (DALYs), and age-standardized DALY rate between 1990 and 2019 by region, etiology, age, and sex, and calculated the estimated annual percentage change (EAPC) of the rate to evaluate the epidemiological trends. RESULTS Globally, incident cases of CKD increased from 7.80 million in 1990 to 18.99 million in 2019, and DALYs increased from 21.50 million to 41.54 million. ASIR increased with an EAPC of 0.69 (95% uncertainty interval [UI] 0.49-0.89) and reached 233.65 per 100,000 in 2019, while the age-standardized DALY rate increased with an EAPC of 0.30 (95% UI 0.17-0.43) and reached 514.86 per 100,000. North Africa and the Middle East, central Latin America, and North America had the highest ASIR in 2019. Central Latin America had the highest age-standardized DALY rate, meanwhile. Almost all countries experienced an increase in ASIR, and over 50% of countries had an increasing trend in age-standardized DALY rate from 1990 to 2019. CKD due to diabetes mellitus type 2 and hypertension accounted for the largest disease burden with 85% incident cases and 66% DALYs in 2019 of known causes, with the highest growth in age-standardized DALY rate and a similar geographic pattern to that of total CKD. Besides, the highest incidence rate of total and four specific CKDs were identified in people aged 70 plus years, who also had the highest DALY rate with a stable trend after 2010. Females had a higher ASIR, while males had a higher age-standardized DALY rate, the gap of which was most distinctive in CKD due to hypertension. CONCLUSION The disease burden of CKD remains substantial and continues to grow globally. From 1990 to 2019, global incident cases of CKD have more than doubled and DALYs have almost doubled, and surpassed 40 million years. CKD due to diabetes mellitus type 2 and hypertension contributed nearly 2/3 of DALYs in 2019 of known causes, and had witnessed the highest growth in age-standardized DALY rate. Etiology-specific prevention strategies should be placed as a high priority on the goal of precise control of CKD.

Abstract
Fresh mushrooms (Flammulina velutipes) are very perishable and easily brown; also they undergo postharvest loss of nutritive constituents. In this study, cinnamaldehyde (CA) emulsion was prepared by using soybean phospholipids (SP) as emulsifier and pullulan (Pul) as stabilizer. The effect of emulsion on the quality of mushroom during storage was also studied. The experimental results indicated that the emulsion obtained by adding 6 % pullulan was found to the most uniform and stable, which is beneficial to its application. Emulsion coating maintained the storage quality of Flammulina velutipes. The incorporation of CA emulsion into the coating system showed a positive effect on inhibiting the accumulation of reactive oxygen species, resulting from improving the effectiveness of delaying active free radical scavenging enzymes. The shelf life of mushrooms coated with emulsion was significantly prolonged, which indicates its potential application in food preservation.

Abstract
Two-dimensional (2D) membrane materials are widely employed for the accurate sieving of ionic contaminants and are of great importance for water reuse. However, 2D membrane materials often suffer from uneven thickness and surface defects, which severely limit their application prospects. Herein, a continuous 2D membrane (LCUM/D) was prepared using cellulose nanofibrils (CNFs) as the support backbone for the assembled layered double hydroxides (LDHs) and dopamine (DA) as the adhesive. The results demonstrated that LDHs could be uniformly distributed in the network structure of CNFs, and the defects on the membrane surface could be effectively compensated by DA. Simultaneously, the continuous LCUM/D showed excellent rejection (97.18%) and selectivity of ionic contaminants tellurium. Dopamine not only compensated for the surface defects of the 2D membrane and enhanced the rejection of tellurium, but also caused no significant loss of water permeance. Moreover, the LCUM/D exhibited stability, which facilitated its long-term application. In addition, the improved hydrophilicity allowed LCUM/D satisfactory anti-fouling properties. This study provides new dimensional insights into the fabrication of continuous 2D membranes for the removal of ionic contaminant and enhances their application prospects in wastewater treatment.

Abstract
AIM To compare the diagnostic performance of mono-exponential model-derived apparent diffusion coefficient (ADC), continuous-time random-walk (CTRW) model-derived Dm, α, β and their combinations in discriminating malignancy of breast lesions, and investigate the association between model-derived parameters and prognosis-related immunohistochemical indices. MATERIALS AND METHODS A total of 85 patients with breast lesions (51 malignant, 34 benign) were analysed in this retrospective study. Clinical characteristics include oestrogen receptor (ER), progesterone receptor (PR), human epidermal receptor 2 (HER2), and Ki-67. The ADC was fitted using a mono-exponential model (b-values = 0, 800 s/mm2), while Dm, α, and β were fitted using a CTRW model. Independent Student's t-test and the Mann-Whitney U-test were used for the comparison of parameters. Discrimination performance was accomplished by receiver operating characteristic (ROC) analysis, and Spearman's correlation analysis was used to explore the association between immunohistochemical indices and diffusion parameters, the statistical significance level was p<0.05. RESULTS Dm and ADC demonstrated similar performance in differentiating malignant and benign lesions (AUC = 0.928 versus 0.930), while the combination of Dm, α, and β could improve the AUC to 0.969. The combined parameter generated by ADC, Dm, α, and β was effective in identifying the ER+/ER- and PR+/PR- patients. Temporal heterogeneity parameter α correlated significantly with the expression of PR. CONCLUSION Diffusion parameters derived from the CTRW model could effectively discriminate the malignancy of breast lesions. Meanwhile, the hormone receptor expression could be distinguished by combined diffusion parameters, and have the potential to reflect the prognosis.

Abstract
BACKGROUND The success of immune checkpoint inhibitors has revolutionized cancer treatment options and triggered development of new complementary immunotherapeutic strategies, including T-cell co-stimulatory molecules, such as glucocorticoid-induced tumor necrosis factor receptor-related protein (GITR). BMS-986156 is a fully agonistic human immunoglobulin G subclass 1 monoclonal antibody targeting GITR. We recently presented the clinical data for BMS-986156 with or without nivolumab, which demonstrated no compelling evidence of clinical activity in patients with advanced solid tumors. Here, we further report the pharmacodynamic (PD) biomarker data from this open-label, first-in-human, phase I/IIa study of BMS-986156 ± nivolumab in patients with advanced solid tumors (NCT02598960). MATERIALS AND METHODS We analyzed PD changes of circulating immune cell subsets and cytokines in peripheral blood or serum samples collected from a dataset of 292 patients with solid tumors before and during treatment with BMS-986156 ± nivolumab. PD changes in the tumor immune microenvironment were measured by immunohistochemistry and a targeted gene expression panel. RESULTS BMS-986156 + nivolumab induced a significant increase in peripheral T-cell and natural killer (NK) cell proliferation and activation, accompanied by production of proinflammatory cytokines. However, no significant changes in expression of CD8A, programmed death-ligand 1, tumor necrosis factor receptor superfamily members, or key genes linked with functional parameters of T and NK cells were observed in tumor tissue upon treatment with BMS-986156. CONCLUSIONS Despite the robust evidence of peripheral PD activity of BMS-986156, with or without nivolumab, limited evidence of T- or NK cell activation in the tumor microenvironment was observed. The data therefore explain, at least in part, the lack of clinical activity of BMS-986156 with or without nivolumab in unselected populations of cancer patients.

Abstract
BACKGROUND Stroke is one of the leading causes of disability and mortality in patients with type 2 diabetes mellitus (T2DM). Risk models have been developed for predicting stroke and stroke-associated mortality among patients with T2DM. Here, we evaluated risk factors of stroke for individualized prevention measures in patients with T2DM in northern China. METHODS In the community-based Tianjin Chronic Disease Cohort study, 58,042 patients were enrolled between January 2014 and December 2019. We used multiple imputation (MI) to impute missing variables and univariate and multivariate Cox's proportional hazard regression to screen risk factors of stroke. Furthermore, we established and validated first-ever prediction models for stroke (Model 1 and Model 2) and death from stroke (Model 3) and evaluated their performance. RESULTS In the derivation and validation groups, the area under the curves (AUCs) of Models 1-3 was better at 5 years than at 8 years. The Harrell's C-index for all models was above 0.7. All models had good calibration, discrimination, and clinical net benefit. Sensitivity analysis using the MI dataset indicated that all models had good and stable prediction performance. CONCLUSION In this study, we developed and validated first-ever risk prediction models for stroke and death from stroke in patients with T2DM, with good discrimination and calibration observed in all models. Based on lifestyle, demographic characteristics, and laboratory examination, these models could provide multidimensional management and individualized risk assessment. However, the models developed here may only be applicable to Han Chinese.

Abstract
Bar code image recognition is a key technology in modern logistics management. An efficient identification system is built based on manifold learning and fuzzy SVM. By integrating the fractal image segmentation technology, it realizes high automatic classification and identification of bar code image. At first, the authors conduct the preprocessing of the collected code image, including three steps, tilt correction, image binarization based on globally dynamic threshold, and fractal segmentation technology. Then, a graph-based fuzzy support vector machine is proposed to realize the high accuracy classification and identification. Experimental results indicate that the accuracy of the proposed method is higher than other compared methods in both pure and noisy samples, reaching 96.6% and 94.5%. And no huge decrease exists when some noise is added to the pure dataset, and the percentage is only 2.1%, which is much lower than the drop of other methods. It shows that the proposed method can significantly promote the identification accuracy, the generalization, and robustness to noise.

Abstract
PURPOSE To investigate the relationship between fibrinogen-like protein 1 (FGL-1) concentrations and various metabolic characteristics in patients with polycystic ovary syndrome (PCOS) and explore whether FGL-1 could be a predictive biomarker for PCOS. METHODS This case-control study included 136 patients with PCOS and 34 normal controls recruited in the Department of Endocrinology and Metabolism, Shanghai Tenth People's Hospital between May 2017 and June 2021. Anthropometric characteristics, metabolic parameters, and reproductive hormones were collected. Serum FGL-1 measurement was conducted using enzyme-linked immunosorbent assay (ELISA) kits. RESULTS Serum FGL-1 concentrations were higher in patients with PCOS than in control subjects in body mass index (BMI) subgroups, insulin resistance (IR) subgroups, and hepatic function subgroups, respectively. Serum FGL-1 concentrations were significantly associated with BMI, glycosylated hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), homeostasis model assessment of insulin resistance (HOMA-IR), alanine aminotransferase (ALT), aspartate aminotransferase (AST), high-density lipoprotein cholesterol (HDL-c), and serum uric acid (SUA) in all individuals. The receiver operating characteristic (ROC) curve analysis revealed that the best cutoff value for FGL-1 levels to predict PCOS was 21.02 ng/ml with a sensitivity of 74.3% and a specificity of 70.6%. Both univariate and multiple logistic regressions indicated that the odds ratio (OR) for PCOS significantly increased in the subjects with high levels of FGL-1. CONCLUSION In our study, FGL-1 was associated with serum aminotransferase and various metabolic indexes. Moreover, the high risk of PCOS was independently associated with the increased FGL-1 levels, which suggested that FGL-1 could be a predictive biomarker for PCOS.

Abstract
Background There are still differences in the prognostic factors of renal cell carcinoma with sarcomatoid dedifferentiation (sRCC). The aim of this study was to evaluate important predictors of survival in patients with sRCC. Patients and methods A comprehensive search of PubMed, Embase, and Cochrane Library was conducted to identify eligible studies. The endpoints embraced overall survival (OS), cancer-specific survival (CSS), and progression-free survival (PFS). Hazard ratios (HRs) and related 95% confidence intervals (CIs) were extracted. Results A total of 13 studies were included for analyses. The pooled results showed that high European Cooperative Oncology Group performance score (HR 2.39, 95% CI 1.32–4.30; P = 0.004), high T stage (HR 2.18, 95% CI 1.66–2.86; P < 0.001), positive lymph node (HR 1.54, 95% CI 1.40–1.69; P < 0.001), distant metastasis (HR 2.52, 95% CI 1.99–3.21; P < 0.001), lung metastases (HR 1.45, 95% CI 1.16–1.80; P < 0.001), liver metastases (HR 1.71, 95% CI 1.30–2.25; P < 0.001), tumor necrosis (HR 1.78, 95% CI 1.14–2.80; P = 0.010), and percentage sarcomatoid ≥50% (HR 2.35, 95% CI 1.57–3.52; P < 0.001) were associated with unfavorable OS. Positive lymph node (HR 1.57, 95% CI 1.33–1.85; P < 0.001) and high neutrophil to lymphocyte ratio (HR 1.16, 95% CI 1.04–1.29; P = 0.008) were associated with unfavorable CSS. High T stage (HR 1.93 95% CI 1.44–2.58; P < 0.001) was associated with unfavorable progression-free survival. Conclusions A meta-analysis of available data identified important prognostic factors for CSS, OS, and PFS of sRCC, which should be systematically evaluated for patient counseling, risk stratification, and treatment selection.

Abstract
BACKGROUND Human herpes virus-6B (HHV-6B) was suggested as an important etiologic factor of mesial temporal lobe epilepsy, while the mechanism is still unknown. Here, we aimed to analyze antigens representing latent, early and late HHV-6B infection and the association with inflammatory cytokines in brain tissue and cerebral spinal fluid (CSF) from MTLE patients with HHV-6B-positivity. METHODS Nested polymerase chain reaction (nPCR), real-time PCR, immunohistochemistry (ICH) and suspension bead array for cytokines were performed. RESULTS Nested polymerase chain reaction (nPCR) in brain tissue revealed HHV-6B DNA in 19 of 49 MTLE patients (39%) and 1 of 19 controls (5%) (P < 0.001), but not in CSF. ICH showed HHV-6B early antigen (P41) positivity in 3 patients (6%), late antigen (gp116/54/64) positivity in 5 patients (10%), latent antigen (U94) positivity in 8 patients (16%), and multiple antigen (early and late or/and latent) positivity in 9 patients (18%). None of these HHV-6B related proteins were found positive in control brain tissue. PCR revealed significant up-regulation of IL-1a, IL-2 and IL-7 mRNA levels in the brain tissue from MTLE patients expressing early antigens compared to those expressing late, latent, multiple antigens, negative antigens and the controls. Suspension bead array of the CSF confirmed significant up-regulation of IL-1a and IL-7 protein expression from MTLE patients expressing early antigens compared to the other groups. CONCLUSIONS Our finding suggests HHV-6B is a common etiologic agent of MTLE. Different virus life cycle may play an important modifying role in inflammatory biology that warrants further investigation. Though virus DNA is difficult detected in CSF, up-regulation of IL-1a and IL-7 in CSF indicates the two cytokines may be taken as indirect biomarker of HHV-6B infection.

Abstract
BACKGROUND Data regarding the influence of patatin-like phospholipase domain-containing 3 (PNPLA3) polymorphism for patients with liver cirrhosis (LC) are scarce. OBJECTIVE This study assesses the role of the PNPLA3 polymorphism for the development of LC and its complications by the findings of genetic examinations. METHODS Patients with LC caused by virus (n = 157), alcohol (n = 104), nonalcoholic fatty liver disease (NAFLD) (n = 106), or autoimmune disease (n = 33) and without LC (n = 128) were enrolled. LC was composed of the presence and absence of complications, such as variceal bleeding, hepatic ascites, and hepatic encephalopathy. To assess the role of the PNPLA3 polymorphism, odds ratio (OR) for the rs738409 variant was calculated for the patients between (i) with LC and without LC in the entire cohort and (ii) the presence and absence of complications in the patients with LC. RESULTS There was a significant difference among the patients without LC and those with alcohol, NAFLD-related LC in the frequency of G alleles (p < 0.001, both). According to complications of LC, the OR for NAFLD-related cirrhosis significantly increased in the presence of the two mutated alleles (OR = 3.165; p = 0.046) when the wild type was used as the reference. However, there were no significant risks for the complications in the virus and alcohol-related cirrhosis unless there was a presence of G alleles. CONCLUSION The PNPLA3 polymorphism was associated with the risk of NAFLD-related LC and its complications.

Abstract
Background Lenvatinib is appropriate for reducing the production of nitric oxide (NO) and facilitating as block angiogenesis. However, to our knowledge, there are no data that support the correlation between NO and clinical response in patients who received lenvatinib therapy for HCC. Therefore, we investigated the correlation between the change rate of NO levels and clinical responses including adverse events (AEs) after lenvatinib therapy for unresectable hepatocellular carcinoma (HCC). Methods This study was conducted using previously collected data from another study. We enrolled 70 patients who received lenvatinib for advanced or unresectable HCC. NO was measured by converting nitrate (NO3−) to nitrite (NO2−) with nitrate reductase, followed by quantitation of NO2− based on Griess reagent. To determine whether lenvatinib influences NO in unresectable HCC, we evaluated the influence of the change rate of NO from baseline after administration of lenvatinib on maximal therapeutic response and SAE. Results After lenvatinib administration, a change rate in the NO from 0.27 to 4.16 was observed. There was no difference between the clinical response to lenvatinib and the change rate of NO (p = 0.632). However, the change rate of NO was significantly lower in patients with AEs than in those without AEs (p = 0.030). When a reduction in NO rate of < 0.8 was defined as a clinically significant reduction of NO (CSRN), the CSRN group had significantly worse progression-free survival (PFS) and overall survival (OS) than the non-CSRN group (p = 0.029 and p = 0.005, respectively). Conclusion Decreased NO levels were associated with the occurrence of AEs and worse prognosis after lenvatinib administration. Change rate in serum NO can be used as predictive markers in patients receiving lenvatinib therapy for HCC.

Abstract
Background Diabetic kidney disease (DKD) is the primary cause of end-stage renal disease, raising a considerable burden worldwide. Recognizing novel biomarkers by metabolomics can shed light on new biochemical insight to benefit DKD diagnostics and therapeutics. We hypothesized that serum metabolites can serve as biomarkers in the progression of DKD. Methods A cross-sectional study of 1,043 plasma metabolites by untargeted LC/MS among 89 participants identified associations between proteinuria severity and metabolites difference. Pathway analysis from differently expressed metabolites was used to determine perturbed metabolism pathways. The results were replicated in an independent, cross-sectional cohort of 83 individuals. Correlation and prediction values were used to examine the association between plasma metabolites level and proteinuria amount. Results Diabetes, and diabetic kidney disease with different ranges of proteinuria have shown different metabolites patterns. Cysteine and methionine metabolism pathway, and Taurine and hypotaurine metabolism pathway were distinguishable in the existence of DKD in DC (diabetes controls without kidney disease), and DKD with different ranges of proteinuria. Two interesting tetrapeptides (Asn-Met-Cys-Ser and Asn-Cys-Pro-Pro) circulating levels were elevated with the DKD proteinuria progression. Conclusions These findings underscore that serum metabolomics provide us biochemical perspectives to identify some clinically relevant physiopathologic biomarkers of DKD progression.

Abstract
Sirtuin 1 (SIRT1) is a nicotinamide adenine dinucleotide (NAD[Formula: see text]-dependent deacetylase involved in multiple glucose metabolism pathways and plays an important role in the pathogenesis of diabetes mellitus (DM). The enzyme specifically recognizes its deacetylation substrates' peptide segments containing a central acetyl-lysine residue as well as a number of amino acids flanking the central residue. In this study, we attempted to ascertain the minimal sequence requirement (MSR) around the central acetyl-lysine residue of SIRT1 substrate-recognition sites as well as the amino acid preference (AAP) at different residues of the MSR window through quantitative structure-activity relationship (QSAR) strategy, which would benefit our understanding of SIRT1 substrate specificity at the molecular level and is also helpful to rationally design substrate-mimicking peptidic agents against DM by competitively targeting SIRT1 active site. In this procedure, a large-scale dataset containing 6801 13-mer acetyl-lysine peptides (and their SIRT1-catalyized deacetylation activities) were compiled to train 10 QSAR regression models developed by systematic combination of machine learning methods (PLS and SVM) and five amino acids descriptors (DPPS, T-scale, MolSurf, [Formula: see text]-score, and FASGAI). The two best QSAR models (PLS+FASGAI and SVM+DPPS) were then employed to statistically examine the contribution of residue positions to the deacetylation activity of acetyl-lysine peptide substrates, revealing that the MSR can be represented by 5-mer acetyl-lysine peptides that meet a consensus motif X[Formula: see text]X[Formula: see text]X[Formula: see text](AcK)0X[Formula: see text]. Structural analysis found that the X[Formula: see text] and (AcK)0 residues are tightly packed against the enzyme active site and confer both stability and specificity for the enzyme-substrate complex, whereas the X[Formula: see text], X[Formula: see text] and X[Formula: see text] residues are partially exposed to solvent but can also effectively stabilize the complex system. Subsequently, a systematic deacetylation activity change profile (SDACP) was created based on QSAR modeling, from which the AAP for each residue position of MSR was depicted. With the profile, we were able to rationally design an SDACP combinatorial library with promising deacetylation activity, from which nine MSR acetyl-lysine peptides as well as two known SIRT1 acetyl-lysine peptide substrates were tested by using SIRT1 deacetylation assay. It is revealed that the designed peptides exhibit a comparable or even higher activity than the controls, although the former is considerably shorter than the latter.

Abstract
Tellurium is massively used as the main light-absorbing layer component in the manufacturing of CdTe thin-film solar cells, a critical component in the photovoltaic industry. However, the process of manufacturing and renewing components has produced large amounts of tellurium-containing wastewater that is difficult to degrade and poses a serious threat to the aquatic ecosystem and human health. Hence, to achieve the recovery of tellurium resources for reducing their damages, a win-win approach was employed to utilize waste lignin to construct functional copper-doped activated lignin (CAL) adsorbents for selective separation and recovery of tellurium from wastewater. CAL exhibited superior adsorption properties towards tellurium (248.45 mg/g), mainly attributed to the adsorption mechanism of coordination interactions. Kinetic and isotherm results elucidated that monolayer chemisorption dominated CAL adsorption process. Besides, CAL had a satisfactory regeneration capability with minimal loss adsorption capacity after six consecutive cycles, which also exhibited high antifouling properties. Meanwhile, CAL achieved high selectivity for tellurium adsorption under the simulated wastewater, revealing the potential of CAL for practical application in wastewater. Therefore, this work provides a promising environmental strategy for exploring the application of lignin-based materials for tellurium recovery from wastewater.

Abstract
OBJECTIVES The purpose of this study was to investigate the association and mediation pathways among muscle mass, muscle function (muscle strength and physical performance), and malnutrition with depressive symptoms clusters in the older hemodialysis patients. DESIGN A multi-center cross-sectional study. SETTING AND PARTICIPANTS A total of 499 patients aged ≥ 60 on hemodialysis from seven facilities in Shanghai of China from 2020 to 2021. MEASUREMENTS Muscle mass was assessed by skeletal muscle index(SMI). Muscle strength was measured by handgrip strength, and physical performance was measured via gait speed and Timed Up and Go Test (TUGT). Nutritional status was assessed by Malnutrition Inflammation Score (MIS). Depressive symptoms were evaluated by the Patient Health Questionnaire-9 (PHQ-9). Logistic regression and mediation analyses fully adjusted for all potential confounding factors. RESULTS Among 499 participants (312 men, mean age 69.2±6.6 years), 108 (21.6%) had depressive symptoms. The muscle strength, physical performance and malnutrition were associated with depressive symptoms. Furthermore, malnutrition significantly mediated the association of muscle function with total, cognitive-affective symptoms. The association of the muscle function with somatic symptoms were mediated by the nutritional status. The mediated proportions of malnutrition in the relationship between physical performance and depressive symptoms clusters were stronger in somatic symptoms than in cognitive-affective symptoms. CONCLUSIONS Our findings suggest that muscle function rather than muscle mass may contribute substantially to the development of depressive symptoms clusters in the hemodialysis via malnutrition. The malnutrition mediated stronger in the association of muscle function with somatic symptoms. These findings may help guide clinicians to better diagnose and manage depression in the context of concomitant muscle function and malnutrition.

Abstract
The development of non-precious metal catalysts for oxygen reduction reactions (ORR) is vital for promising clean energy technologies such as fuel cells, and zinc-air batteries. Herein, we present a stepwise synthesis of N-doped and carbon encapsulated BiOCl-CNTs heterostructures. Electrocatalytic ORR studies show that the optimized catalyst has a high half-wave potential (E1/2) of 0.85 V (vs. RHE), large limiting current density (-5.34 mA cm-2@0.6 V) in alkaline medium, and nearly perfect 4e- reduction characteristics, even surpassing commercial Pt/C. Meanwhile, the catalyst has exceptional durability (above 97.5 % after 40000 s) and strong resistance towards methanol poisoning. The good ORR activity also results in high-performance zinc-air batteries with a specific capacity (724 mAh g-1@10 mA cm-2), a high open-circuit potential of 1.51 V and a peak power density of 170.7 mW cm-2, as well as an ultra-long charge-discharge cycle stability (155 h), comparable with the Pt/C catalyst. The catalytic mechanism reveals that the excellent electrocatalytic performance originates from the synergistic effect of N doping, oxygen vacancies, and BiOCl sites.

Abstract
Designing a bifunctional catalyst for hydrogen oxidation reaction (HOR) and hydrogen evolution reaction (HER) is significant toward developing sustainable hydrogen-electric conversion systems. Herein, a cost-effective bifunctional catalyst, Ru/N-doped Carbon@WO3 -W2 C (Ru/NC@WOC), was developed via co-precipitation and polyol reduction. Ru/NC@WOC showed superior HOR/HER activity in alkaline solution in comparison with commercial Pt/C. HOR electrochemical tests showed that the mass activity at 0.05 V (1.96 m A μ g R u - 1 ) and exchange-current density were 7.5 and 1.2 times that of Pt/C. Additionality, Ru/NC@WOC exhibited up 30-fold HOR activity in mass activity compared with benchmark Ru/C. Moreover, it also displayed exceptional electrocatalytic HER with overpotentials of 31 mV at 10 mA cm-2 and 119 mV at 100 mA cm-2 , surpassing Pt/C, benchmark Ru/C, and most of the previously reported electrocatalysts. The outstanding catalytic activity of Ru/NC@WOC probably arises from the synergy between Ru and NC@WOC matrix, suitable hydrogen binding energy, and highly conductive substrate. Thus, this work may pave a new avenue to fabricate low-cost bifunctional HOR/HER catalysts for alkaline fuel cells and water electrolyzer.

Abstract
BACKGROUND Data regarding the additional effect on the recurrence of hepatic encephalopathy (HE) after oral L-carnitine administration are scarce. OBJECTIVE This study aimed to assess the additional effects of L-carnitine in patients who were receiving rifaximin for HE. METHODS This randomized study comprised a screening visit and a 12-week treatment period. Patients who fulfilled the eligibility criteria were randomized to either group A (additional rifaximin) or group B (additional L-carnitine and rifaximin). Group A received 1,200 mg/day of rifaximin. Group B received 1,500 mg/day of L-carnitine and rifaximin at 1,200 mg/day. The endpoints were the changes in the portal systemic encephalopathy (PSE) index and the admission rate from the baseline for the duration of the study in both groups. RESULTS Eighty-three patients were randomized to either group A (n = 42) or group B (n = 41). In group A, the PSE index decreased from 0.35 ± 0.09 at baseline to 0.27 ± 0.11 on the final evaluation day (p = 0.001). In group B, the PSE index decreased from 0.37 ± 0.09 at baseline to 0.24 ± 0.11 on the final evaluation day (p = 0.001). Although there was not a significant reduction in the PSE index in group A compared to that in group B (p = 0.202), the admission rates were 30.9% and 9.8% in groups A and B, respectively. Additional L-carnitine significantly reduced the admission rate (p = 0.028). CONCLUSION L-Carnitine addition reduced the risk of hospitalization for patients who received rifaximin for HE.

Abstract
The purpose of this retrospective study was to introduce the use of an alternative vascularized bone graft for treating scaphoid non-union. The vascularized bone graft was harvested from the dorsal base of the third metacarpal bone. From May 2014 to September 2017, 29 patients with scaphoid non-union were treated. Grip and pinch strengths were compared to the contralateral side. The patients rated wrist joint pain on a visual analogue scale. Wrist function was assessed on Mayo Wrist Score. p < 0.05 was considered statistically significant. 18 scaphoids healed at 6 weeks and the other 11 at 16 weeks. Follow-up ranged from 28 to 73 months, for a mean 48 months. At final follow-up, mean wrist flexion had improved from 65° (range, 51°-81°) preoperatively to 72° (range, 61-78°) (p > 0.05), for a contralateral value of 74° (range, 65°-86°). Mean extension had improved from 56° (range, 44°-72°) to 60° (range, 47°-76°) (p > 0.05) for a contralateral value of 66° (range, 52°-80°). Mean wrist pain improved from 4 (range, 3-8) to 2 (range, 0-4) (p < 0.05). Mean pinch strength improved from 6.4 kg (range, 5.2-7.3 kg) to 8.6 kg (6.1-9.9 kg) (p < 0.05). Mayo Wrist Score improved from 49 (range, 10-65) to 92 (range, 70-100) (p < 0.05). Transferring a vascularized bone graft harvested from the base of the third metacarpal bone was an effective alternative for the treatment of scaphoid non-union, achieving bone healing and normal wrist function without significant donor-site morbidity. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Accruing research shows the implications of long non-coding RNAs (lncRNAs) in the progression of various autoimmune diseases including systemic lupus erythematosus (SLE). The present study aimed to identify the expression pattern of LINC00176 in SLE and to explore its effects on CD4+T cell adhesion in this context. The biological functions of LINC00176, WIF1 and WNT5a on CD4+T cells in SLE were evaluated via gain- and loss-of-function experiments, following delivery of pcDNA3-LINC00176, siRNA-LINC00176, pcDNA3-WIF1 and WNT-sFRP5 (an inhibitor for the WNT5a signaling pathway). High LINC00176 expression was evident in the CD4+T cells of SLE patients. Additionally, WIF1 was identified as a potential target gene of LINC00176, and was negatively regulated by LINC00176. The overexpression of LINC00176 could promote proliferation and adhesion of CD4+T cells in SLE. Such alternations were reversed following up-regulation of WIF1 or inhibition of the WNT5a signaling pathway. Taken together, the key findings of our study highlight the ability of LINC00176 to potentially promote the proliferation and adhesion of CD4+T cells in SLE by down-regulating WIF1 and activating the WNT5a signaling pathway, providing new insight and a theoretical basis for translation in SLE therapy.

Abstract
Background To compare perioperative, functional and oncological outcomes between transperitoneal robotic partial nephrectomy (TRPN) and retroperitoneal robotic partial nephrectomy (RRPN). Methods A literature searching of Pubmed, Embase, Cochrane Library and Web of Science was performed in August, 2020. Pooled odds ratios (ORs) or weighted mean differences (WMDs) with 95% confidence intervals (CIs) were estimated using fixed-effect or random-effect model. Publication bias was evaluated with funnel plots. Only comparative studies with matched design or similar baseline characteristics were included. Results Eleven studies embracing 2,984 patients were included. There was no significant difference between the two groups regarding conversion to open (P = 0.44) or radical (P = 0.31) surgery, all complications (P = 0.06), major complications (P = 0.07), warm ischemia time (P = 0.73), positive surgical margin (P = 0.87), decline in eGFR (P = 0.42), CKD upstaging (P = 0.72), and total recurrence (P = 0.66). Patients undergoing TRPN had a significant higher minor complications (P = 0.04; OR: 1.39; 95% CI, 1.01–1.91), longer operative time (P < 0.001; WMD: 21.68; 95% CI, 11.61 to 31.76), more estimated blood loss (EBL, P = 0.002; WMD: 40.94; 95% CI, 14.87 to 67.01), longer length of hospital stay (LOS, P < 0.001; WMD: 0.86; 95% CI, 0.35 to 1.37). No obvious publication bias was identified. Conclusion RRPN is more favorable than TRPN in terms of less minor complications, shorter operative time, less EBL, and shorter LOS. Methodological limitations of the included studies should be considered while interpreting these results.

Abstract
OBJECTIVE The aim of this study was to explore the effect of micro ribonucleic acid (miR)-133 on kidney injury in rats with diabetic nephropathy (DN) through the mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) pathway. MATERIALS AND METHODS The model of DN was first established in rats. Blood glucose, renal index, urinary micro-albumin (UMA), and creatinine clearance rate (CCr) were detected. Meanwhile, the protein expression levels of miR-133, kidney injury molecule-1 (KIM-1) and anti-inflammatory cytokine interleukin-8 (IL-8) were measured using Western blotting. Human renal proximal tubular epithelial cell line human kidney-2 (HK-2) was treated with high glucose to simulate DN cells in vivo. Subsequently, Western blotting was performed to detect the protein expression of KIM-1. After HK-2 cells were treated with high glucose and silenced miR-133 for 24 h, the expression changes in KIM-1 was evaluated. RESULTS In DN group, blood glucose, renal index, UMA, and CCr were all markedly higher than those of control group. This indicated the successful establishment of DN model in rats. The expression level of miR-133 was significantly up-regulated in DN model rats. Meanwhile, the downstream protein phosphorylated-EPK (p-EPK) showed a significantly increasing trend as well. Additionally, the protein expressions of KIM-1 and IL-8 were notably elevated. High-glucose-treated HK-2 cells showed significantly up-regulated expression levels of miR-133, KIM-1, and IL-8. After 24 h of combined treatment with high glucose and miR-133 silence, the expressions of KIM-1 and IL-8 were markedly down-regulated. CONCLUSIONS MiR-133 may be related to the occurrence and development of DN. The silence of miR-133 inhibits kidney injury in DN via the MAPK/ERK signaling pathway. Our findings suggest that miR-133 may be an effective target for the treatment of DN.

Abstract
We report the experimental observation of Faraday waves on soft gels. These were obtained using agarose in a mechanically vibrated cylindrical container. Low driving frequencies induce subharmonic standing waves with spatial structure that conforms to the geometry of the container. We report the experimental observation of the first 15 resonant Faraday wave modes that can be defined by the mode number (n,ℓ) pair. We also characterize the shape of the instability tongue and show the complex dependence upon material properties can be understood as an elastocapillary effect.

Abstract
AIM Esophageal variceal ligation (EVL) is usually carried out to decrease the risk of hemorrhage. Several complications have been reported with the procedure, including bleeding from ligation-induced esophageal ulcers or heartburn. However, there is scant evidence for gastroesophageal reflux caused by EVL. The aim of this study was to assess 24-h pH monitoring in the esophagogastric junction before and after EVL and the bleeding rate for 18 months. METHODS We undertook this single-center prospective trial in Kitasato University Hospital (Sagamihara, Japan). We included patients with cirrhosis who were Child-Pugh classification A or B, without uncontrollable hepatocellular carcinoma, and had F2 or larger esophageal varices, and/or were red color sign (RC) positive. The study period was from July 2012 through September 2017 for 32 patients enrolled in this study and followed up until March 2019. RESULTS Baseline characteristics were: median Child-Pugh score, 6; and mean age, 64.3 years. Before and after EVL, the median 24-h under pH 4 holding time percentages of all patients were 0.6% (range, 0-5.6%) and 0.95% (range, 0-50.6%), respectively, without a significant difference (P = 0.107). We could not find any G3 or G4 adverse events during this study, and 75% of the patients who had already suffered from moderate gastroesophageal reflux became worse after EVL (P = 0.18) and required antacid therapies. There were no patients with hemorrhage from esophageal varices. CONCLUSIONS Esophageal variceal ligation for esophageal varices did not significantly change gastroesophageal reflux. Therefore, acid suppressive therapy might be unnecessary for patients who do not suffer from gastroesophageal reflux after EVL.

Abstract
OBJECTIVE To elucidate the association between cigarette smoking and the susceptibility of acute myeloid leukemia (AML). MATERIALS AND METHODS We searched relevant articles from PubMed, Embase, and Cochrane by 1st December, 2018. This meta-analysis included 20 case-control studies, involving 7,538 AML patients and 137,924 healthy controls. Studies reported OR and 95%CI of the correlation between cigarette smoking and AML susceptibility were eligible. Subsequently, the included data were weighted by an inverse variance and analyzed using fixed-effects or random-effects model. Subgroup analysis was conducted based on ethnicities and sources of controls. Heterogeneity test was applied for the included articles. Data analyses were conducted using STATA 12.0. RESULTS Current smokers (OR=1.42, 95%CI= 1.28-1.57; p=0.392) and ever-smokers (OR=1.16, 95%CI=1.05-1.28; p=0.036) were associated with AML susceptibility. In the subgroup analysis by ethnicity, only current smokers (OR=1.45, 95%CI=1.29-1.63; p=0.371) and ever-smokers (OR=1.16, 95%CI=1.03-1.30; p=0.034) of the Caucasian population were associated with AML susceptibility. Stratified analysis based on SOC (source of controls) indicated increased susceptibility of AML in current smokers (OR=1.43, 95%CI=1.26-1.63; p=0.283) and ever-smokers (OR=1.20, 95%CI=1.07-1.35; p=0.078) of the population-based group. Nevertheless, only current smokers in the hospital-based group had increased susceptibility of AML (OR=1.45, 95%CI=1.19-1.76; p=0.198). The risks of AML in ever-smokers (OR=1.04, 95%CI = 0.81-1.35; p=0.054) of the hospital-based group did not remarkably changed. CONCLUSIONS In this meta-analysis, we confirmed the association between cigarette smoking and onset risk of AML, especially in the Caucasian population. High-quality, large-scale researches are required to be conducted in multi-center hospitals for verification.

Abstract
Abdominal ultrasound in a 50-year-old Japanese man revealed a cystic lesion on the caudate lobe of the liver. Four-month follow-up imaging showed a rapid increase in the size of the cystic lesion. The patient underwent laparoscopic partial hepatectomy because of a suspicion and perceived risk that the lesion might be malignant. The initial histological diagnosis was a hepatic cyst. Eleven months later, computed tomography showed a giant cystic lesion in the abdominal cavity and multiple liver metastases. The patient underwent excision of the giant cystic lesion and a partial hepatectomy. Immunohistochemistry for the recurring lesion revealed undifferentiated embryonal sarcoma of the liver.

Abstract
Podocyte injury plays a vital role in proteinuria and nephrotic syndrome. Calcineurin (CaN) inhibitors are effective in reducing proteinuria. However, their molecular mechanism is still not fully understood. Angiopoietin-like-4 (ANGPTL4) is a secreted protein that mediates proteinuria in podocyte-related nephropathy. In this study, we established a puromycin aminonucleoside (PAN)-induced minimal-change disease (MCD) rat model and a cultured podocyte injury model. We found that CaN inhibitors protected against PAN-induced podocyte injury, accompanied by an inhibition of Nfatc1 and Angptl4 both in vivo and in vitro. Nfatc1 overexpression and knockdown experiments indicated that Angptl4 was regulated by Nfatc1 in podocytes. ChIP assays further demonstrated that Nfatc1 increased Angptl4 expression by binding to the Angptl4 promoter. In addition, overexpression and knockdown of Angptl4 revealed that Angptl4 directly induced rearrangement of the cytoskeleton of podocytes, reduced the expression of synaptopodin, and enhanced PAN-induced podocyte apoptosis. Furthermore, in a cohort of 83 MCD and 94 membranous nephropathy (MN) patients, we found increased expression of serum ANGPTL4 compared to 120 healthy controls, and there were close correlations between serum ANGPTL4 and Alb, urinary protein, urinary Alb, eGFR, Scr, and BUN in MCD patients. No obvious correlation was found in MN patients. Immunofluorescence studies indicated that increased ANGPTL4 in MCD and MN patients was located mostly in podocytes. In conclusion, our results demonstrate that CaN inhibitors ameliorate PAN-induced podocyte injury by targeting Angptl4 through the NFAT pathway, and Angptl4 plays a vital role in podocyte injury and is involved in human podocyte-related nephropathy. © 2020 The Pathological Society of Great Britain and Ireland.

Abstract
AIM Lenvatinib is an oral, multitargeted, tyrosine kinase inhibitor, which suppress tumor angiogenesis and tumor progression. It was non-inferior to sorafenib in overall survival in untreated advanced hepatocellular carcinoma (HCC). Sorafenib had a beneficial effect on portocollateral circulation with portal hypertension in translating and clinical studies. However, the hemodynamic effects of lenvatinib appear to be different from those of sorafenib because the efficacy of lenvatinib for vascular endothelial growth factor receptors and fibroblast growth factor receptors is different from that of sorafenib. This study was prospectively performed to evaluate the portal hemodynamic effect of lenvatinib in patients with advanced HCC using duplex Doppler ultrasonography. METHODS In total, 28 Child-Pugh class A or B patients with advanced HCC received lenvatinib depending on body weight daily for 2 weeks. Primary outcomes were changes in the hemodynamics of the portal venous system using duplex Doppler ultrasonography before and after the 2-week administration of lenvatinib. RESULTS The portal venous flow velocity (cm/s) significantly reduced (27 ± 12.1 vs. 22.6 ± 8.0, P = 0.019), while portal venous area (cm2 ) did not change after the 2-week administration (0.80 ± 0.36 vs. 0.82 ± 0.27, P = 0.665). Therefore, the congestion index (portal venous area/portal venous flow velocity), which reflects the pathophysiological hemodynamics of the portal venous system significantly worsened (0.037 ± 0.025 vs. 0.043 ± 0.024, P = 0.045). CONCLUSIONS Considering that this was a short-term study, because lenvatinib could be an agent that aggravates portal hypertension, it will be necessary to verify its clinical effects for portal hypertension in future studies.

Abstract
A cancer cell changes its state from being epithelial- to mesenchymal-like in a dynamic manner during tumor progression. For example, it is well known that mesenchymal-to-epithelial transition (MET) is essential for cancer cells to regain the capability of seeding on and then invading secondary/tertiary regions. However, there is no fast yet reliable method for detecting this transition. Here, we showed that membrane undulation of invasive cancer cells could be used as a novel marker for MET detection, both in invasive model cell lines and repopulated circulating tumor cells (rCTCs) from non-small cell lung cancer (NSCLC) patients. Specifically, using atomic force microscopy (AFM), it was found that the surface oscillation spectra of different cancer cells, after undergoing MET, all exhibited two distinct peaks from 0.001 to 0.007 Hz that are absent in the spectra before MET. In addition, by adopting the long short-term memory (LSTM) based recurrent neural network learning algorithm, we showed that the positions of recorded membrane undulation peaks can be used to predict the occurrence of MET in invasive NSCLC cells with high accuracy (>90% for model cell lines and >80% for rCTCs when benchmarking against the conventional bio-marker vimentin). These findings demonstrate the potential of our approach in achieving rapid MET detection with a much reduced cell sample size as well as quantifying changes in the mesenchymal level of tumor cells.

Abstract
BACKGROUND To make an accurate estimate of the response to thrombopoietin (TPO) receptor agonists for thrombocytopenia associated with chronic liver disease, we evaluated the influence of antiplatelet autoantibodies on the response to lusutrombopag in thrombocytopenic patients with liver disease. METHODS A prospective study was conducted at 2 hospitals. Thrombocytopenic patients with liver disease received oral lusutrombopag 3.0 mg once daily for up to 7 days. We analyzed changes in platelet counts from baseline to the maximum platelet count on days 9-14. The definition of clinical response was a platelet count of ≥5 × 104/μL with an increased platelet count of ≥2 × 104/μL from baseline. We assessed the correlation between the response to treatment drug and antiplatelet autoantibodies measured by anti-GPIIb/IIIa antibody-producing B cells. RESULTS Thirty patients received the trial drug. There were 25 responders and 5 nonresponders. The median change in platelet counts was 3.9 × 104/μL (95% CI 2.8-4.6, p < 0.0001). The correlation between change in platelet counts and the frequency of the anti-glycoprotein IIb/IIIa antibody-producing B cells was moderate (r = 0.414, 95% CI 0.064-0.674, p = 0.023). In multivariate analysis of factors affecting the change in platelet counts, the anti-GPIIb/IIIa antibody-producing B cells were identified as an independent factor (regression coefficient [B] = 0.089; CI 0.021-0.157, p = 0.013). CONCLUSION Anti-GPIIb/IIIa antibody-producing B cells may be a predictor for TPO receptor agonists in patients with chronic liver disease.

Abstract
Objective: To investigate the clinical features and risk factors of hospital-associated venous thromboembolism (VTE). Methods: The study enrolled acute VTE patients admitted into China-Japan Friendship Hospital from January 1, 2017 to December 31, 2017. The hospital-associated VTE (HA-VTE) group and the community-associated VTE (CA-VTE) group were classified according to whether the VTE occurred during hospitalization or within a 90-day period of admission to hospital (including inpatient with at least two days of hospital stay or a surgical procedure under general or regional anaesthesia). Differences in clinical features, risk factors, and mortality rate were compared between the two groups. Results: A total of 437 patients with acute VTE were analyzed in the study. Among them, 266 patients were HA-VTE, 171 patients were CA-VTE. Patients in the CA-VTE group were more likely to have varicose veins, sedentary, long-distance travel, and patients in the HA-VTE group were more complicated with recent surgery (<1 month), bed rest, active malignant tumor, acute infections, acute cerebral infarction, fracture, central venous catheter (P<0.05). The CA-VTE group had more clinical symptoms such as lower extremity pain, dyspnea, chest pain and chest tightness (P<0.05). HA-VTE patients had less clinical symptoms but were more severe than the CA-VTE patients, with more sudden deaths (0 vs 3.4%, P=0.035). Among HA-VTE patients, 92.8% experienced VTE during hospitalization or within 1 month of the preceding hospital encounter, with a 13-day median time to VTE. The all-cause mortality rate was higher for HA-VTE group than CA-VTE group (8.3% vs 1.2%, P<0.001), and the in-hospital VTE was more common compared to VTE diagnosed post-discharge (12.2% vs 3.4%, P<0.001). Conclusions: More than half events of VTE are related to recent hospitalizations. HA-VTE has different risk factors from CA-VTE, combined with fewer clinical symptoms but higher all-cause mortality rate. More attention about VTE should be paid to hospitalized patients to reduce the incidence of HA-VTE events.

Abstract
RATIONALE In the course of endocarditis, the development of antineutrophil cytoplasmic antibody (ANCA)-mediated disease introduces the dilemma of determining the best treatment approach for immune conditions, whether immunosuppressant therapy should be added to antibiotic treatment has remained controversial. PATIENT CONCERNS A 33-year-old man presented with progressive fever lasting for 7 months, and swelling, pain, and purpura in the arms and legs. The patient showed multiple autoantibodies including cytoplasmic ANCA, antiproteinase 3, rheumatoid factor, and anti-beta 2 glycoprotein I. Blood culture was positive for viridans streptococcus, and renal biopsy revealed glomerulonephritis and interstitial nephritis. DIAGNOSIS Endocarditis caused by viridans streptococci, ANCA-associated vasculitis, and congenital ventricular septal defect. INTERVENTIONS In addition to effective antibiotics, he also received twice intravenous corticosteroids and intravenous immunoglobulin therapy, and a low dose of cyclophosphamide. At last, the patient received congenital ventricular septal defect repair and debridement. OUTCOMES The abnormal clinical manifestations, including renal failure and loss of strength, recovered rapidly with corticosteroid therapy in addition to antibiotic treatment. After 6 months without any medications, he remained asymptomatic and was able to live normally. LESSONS In this case with endocarditis and ANCA-associated vasculitis, we highlighted the importance of biopsy and immunosuppressive therapy. Histopathologic examination is required for diagnosis and treatment in such case. Identifying patients who have endocarditis and ANCA positivity with vasculitis pathologic features will require corticosteroid/immunosuppressives in addition to the antibiotics therapy.

Abstract
Summary
Envelopes have been proposed in recent years as a nascent methodology for sufficient dimension reduction and efficient parameter estimation in multivariate linear models. We extend the classical definition of envelopes in Cook et al. (2010) to incorporate a nonlinear conditional mean function and a heteroscedastic error. Given any two random vectors ${X}\in\mathbb{R}^{p}$ and ${Y}\in\mathbb{R}^{r}$, we propose two new model-free envelopes, called the martingale difference divergence envelope and the central mean envelope, and study their relationships to the standard envelope in the context of response reduction in multivariate linear models. The martingale difference divergence envelope effectively captures the nonlinearity in the conditional mean without imposing any parametric structure or requiring any tuning in estimation. Heteroscedasticity, or nonconstant conditional covariance of ${Y}\mid{X}$, is further detected by the central mean envelope based on a slicing scheme for the data. We reveal the nested structure of different envelopes: (i) the central mean envelope contains the martingale difference divergence envelope, with equality when ${Y}\mid{X}$ has a constant conditional covariance; and (ii) the martingale difference divergence envelope contains the standard envelope, with equality when ${Y}\mid{X}$ has a linear conditional mean. We develop an estimation procedure that first obtains the martingale difference divergence envelope and then estimates the additional envelope components in the central mean envelope. We establish consistency in envelope estimation of the martingale difference divergence envelope and central mean envelope without stringent model assumptions. Simulations and real-data analysis demonstrate the advantages of the martingale difference divergence envelope and the central mean envelope over the standard envelope in dimension reduction.
