Abstract
l-Threonine aldolase from Actinocorallia herbida (AhLTA) is an ideal catalyst for producing l-threo-4-methylsulfonylphenylserine [(2S,3R)-1 b], a key chiral precursor for florfenicol and thiamphenicol. The moderate Cβ stereoselectivity is the main obstacle to the industrial application of AhLTA. To address this issue, a combinatorial active-site saturation test (CAST) together with sequence conservatism analysis was applied to engineer the AhLTA toward improved Cβ stereoselectivity. The optical mutant Y314R could asymmetrically synthesize l-threo-4-methylsulfonylphenylserine with 81 % diastereomeric excess (de), which is 23 % higher than wild-type AhLTA. Molecular dynamic (MD) simulations revealed that the mechanism for the improvement in Cβ stereoselectivity of Y314R is due to the acylamino group of residues Arg314 controlling the orientation of substrate 4-methylsulfonyl benzaldehyde (1 a) in the active pocket by directed interaction with the methylsulfonyl group; this leads to asymmetric synthesis of l-threo-4-methylsulfonylphenylserine. The success in this study demonstrates that direct control of substrates in an active pocket is an attract strategy to address the Cβ stereoselectivity problem of LTA and contribute to the industrial application of LTA.

Abstract
Diabetic nephropathy the main reason for end stage renal disease is a common microvascular complication in patients with type 1 and type 2 diabetes. The interleukin-6 (IL-6), acting as a pleiotropic cytokine, play key roles in main autoimmune disorders. The recombinant anti-IL-6R fusion proteins (VHH-0031) constructed and obtained in our lab is a dual target-directed single domain-based fusion protein against the interleukin-6 receptor. This study aims to explore the renoprotective effect of VHH-0031 in diabetic nephropathy. VHH-0031 treatment alleviated renal inflammation, morphologic injury and renal insufficiency in both Goto-Kakizaki rats and STZ-induced Sprague Dawley rats. These renoprotective effects of VHH-0031 are associated with alleviating inflammation and suppression of the JAK2/STAT3 signaling pathway. The mesangial cells treated with VHH-0031 exhibited anti-proliferation, anti-inflammation and inactivation of JAK2/STAT3 pathway under high glucose condition. In conclusion, this study demonstrates that VHH-0031 exhibited a potent protective effect in kidney of diabetic rats and its mechanism may be concerned with the inhibition of the IL-6R/JAK2/STAT3 pathway of glomerular mesangial cells.

Abstract
Objective: To observe the clinicopathological features of bronchiolar adenoma (BA) and mixed squamous cell and glandular papilloma (MSGP). The relationship between them was also analyzed. Methods: Clinical data of eight patients with BA and four patients with MSGP diagnosed in China-Japan Friendship Hospital were collected from January 2018 to January 2020. Hematoxylin-eosin staining and immunohistochemical staining (EnVision method) were used to compare their histopathological characteristics. The hotspots regions of cancer-associated driver genes in lung cancer, using real-time quantitative PCR, were detected in all the cases and the literatures were reviewed. Results: The clinical and imaging manifestations of BA and MSGP were analogous. Histologically they had a two-layer structure including bronchial or bronchiolar-type epithelium and a continuous layer of basal cells,similar to bronchial/bronchiole mucosae. P16 protein was highly expressed in 7/8 of BA and 1/4 of MSGP. Mutations of cancer-associated genes were detected in 4/8 of BA, but none in MSGP. Conclusions: BA and MSGP, derived from different parts of the respiratory tract in the lungs, are rare and benign. Their morphological features overlapped with each other, and some cases are accompanied by genetic changes. It is necessary to pay attention to the differential diagnosis between them and lung adenocarcinoma, especially during the intraoperative diagnosis; and be alert to the potentially malignant components in the tumor or combined cancers.

Abstract
PURPOSE We aimed to evaluate the association of early versus late initiation of Continuous renal replacement therapy (CRRT) with mortality in patients with fluid overload. METHODS This was a retrospective cohort study of patients with fluid overload (FO) treated with CRRT due to severe acute kidney injury (AKI) between January 2015 and December 2017 in a mixed medical intensive care unit of a teaching hospital in Beijing, China. Patients were divided into early (≤15 h) and late (>15 h) groups based on the median time from ICU admission to CRRT initiation. The primary outcome was all-cause mortality at day 60. Multivariable Cox model analysis was used for analysis. RESULTS The study patients were male predominant (84/150) with a mean age of 64.8 ± 16.7 years. The median FO value before CRRT initiation was 10.1% [6.2-16.1%]. The 60-day mortality rates in the early vs the late CRRT groups were 53.9% and 73%, respectively. On multivariable Cox modelling, the late initiation of CRRT was independently associated with an increased risk of death at 60 days (HR 1.75, 95% CI 1.11-2.74, p = 0.015). CONCLUSIONS Early initiation of CRRT was independently associated with survival benefits in severe AKI patients with fluid overload.

Abstract
In recent years, calcium nitrate addition has become a promising and usually used method for in situ sediment remediation. In this study, excess calcium nitrate was applied to column sediments to explore the coupling reactions of elements such as N, Fe, S, and P. Diffusive gradients in thin film (DGT) devices were used to collect labile substances at the sediment-water interface. Rhizon samplers were used to collect soluble substances in interstitial water. Results showed that nitrate addition turned the surface sediment into a more oxidized state, and mobile Fe, S, P, and As were removed in surface ~ 10-cm sediment. Due to different nitrate distributions in corresponding sediment depths, the consumption rates of NH3-N and soluble reactive P were faster in the surface sediment than that in deeper layers. Different from previous researches, the transient increase of soluble Fe was observed in this study, which was probably attributed to the solvation of FeS in the autotrophic denitrification process. According to our results, we suggest that a dosage of far less than 141 g N/m2 and slightly more than 45.3 g N/m2 can be used for the remediation of black and odorous sediment and control of internal P by calcium nitrate.

Abstract
Simple Summary Which factors predispose individuals to developing immune-related adverse events (irAEs) remains unclear. In addition, the relationship between irAEs and survival outcomes warrants further investigation. We sought to investigate the association between immunotherapy-related thyroid dysfunction and demographic and clinical characteristics in a diverse urban cohort of patients with lung cancer receiving immune checkpoint inhibitors (ICIs). This study was conducted with the aim of helping to identify patients at a higher risk of experiencing irAEs and clarify whether irAEs portend a survival advantage. Abstract We sought to characterize thyroid dysfunction and its association with baseline clinical and demographic characteristics, as well as progression-free survival (PFS), in a multiethnic cohort of lung cancer patients treated with ICIs. A retrospective chart review of lung cancer patients receiving an anti-PD1 or PD-L1 agent was performed. Multivariate Cox proportional hazards were fitted to compare time to thyroid dysfunction among race subgroups controlling for age, gender, treatment type, and duration. Thyroid dysfunction was based on laboratory testing; clinical symptoms were not required. PFS at a 24-week landmark analysis point among patients with and without thyroid dysfunction was compared using a log-rank test. We identified 205 subjects that received ICIs, including 76 (37.1%) who developed thyroid dysfunction. Rates of thyroid dysfunction by one year occurred at similar frequencies among all races (p = 0.92). Gender and concurrent chemotherapy showed no significant association with thyroid dysfunction (p = 0.81 and p = 0.67, respectively). Thyrotoxicosis occurred at higher rates in Black (25, 31.6%) subjects than in White (7, 16.7%) and Hispanic (8, 12.7%) subjects when employing the log-rank test (p = 0.016) and multivariate Cox regression (HR 0.48, p = 0.09 for White and HR 0.36, p = 0.01 for Hispanic compared to Black subjects). PFS was similar among subjects with and without thyroid dysfunction when applying the log-rank test (p = 0.353). Gender, concurrent treatment with chemotherapy, and PFS were not associated with thyroid dysfunction in patients receiving ICIs; however, Black race was a risk factor for thyrotoxicosis. The mechanisms underlying the role of race in the development of irAEs warrant further study.

Abstract
Fungi can parasitize microalgae, exerting profound impacts on both the aquatic ecosystems and microalgal mass cultures. In this study, the unicellular green alga Haematococcus pluvialis and the blastocladialean fungus Paraphysoderma sedebokerense were used as a model system to address the mechanisms underlying the fungal parasitism on the algal host. High-throughput metabolic assay indicated that P. sedebokerense can utilize several carbon sources with a preference for mannose, glucose and their oligosaccharides, which was compatible with the profile of the host algal cell walls enriched with glucan and mannan. The results of dual transcriptomics analysis suggested that P. sedebokerense can upregulate a large number of putative carbohydrate-activate enzymes (CAZymes) encoding genes, including those coding for the endo-1,4-β-glucanase and endo-1,4-β-mannanase during the infection process. The cell walls of H. pluvialis can be decomposed by both P. sedebokerense and commercial CAZymes (e.g. cellulase and endo-1,4-β-mannanase) to produce mannooligomers, while several putative parasitism-related genes of P. sedebokerense can be in turn upregulated by mannooligomers. In addition, the parasitism can be blocked by interfering the selected CAZymes including glucanase, mannanase and lysozyme with the specific inhibitors, which provided a framework for screening suitable compounds for pathogen mitigation in algal mass culture.

Abstract
Lymphovascular invasion (LVI) and Black race are associated with poorer prognosis in early breast cancer (EBC). We evaluated the association between LVI and race, and whether LVI adds prognostic benefit to the 21-gene recurrence score (RS) in EBC. Women with ER+ HER2- EBC measuring up to 5 cm, with 0-3 involved axillary nodes, diagnosed between 1 January 2010 and 1 January 2014, who underwent surgery as first treatment and had available RS, were identified in the NCDB database. Bivariate associations between two categorical variables were examined using chi-square test. Multivariate Cox proportional hazards model were used to assess the association of LVI, race, and other covariates with overall survival (OS). 77,425 women, 65,018 node-negative (N0), and 12,407 with 1-3 positive (N+) nodes, were included. LVI was present in 12.7%, and associated with poor grade, RS 26-100, and N+ (all p < 0.0001), but not Black race. In multivariate analysis, LVI was associated with worse OS in N0 [HR 1.37 (95% CI 1.27, 1.57], but not N+ EBC. LVI was associated with worse OS in N0 patients with RS 11-25 [HR 1.31 (95% CI 1.09, 1.57)] and ≥26 [HR 1.58 (95% CI 1.30, 1.93)], but not RS 0-10. No interaction between LVI and chemotherapy benefit was seen. Black race was associated with worse OS in N0 (HR 1.21, p = 0.009) and N+ (HR 1.37, p = 0.015) disease. LVI adds prognostic information in ER+, HER2-, N0 BCA with RS 11-100, but does not predict chemotherapy benefit. Black race is associated with worse OS, but not LVI.

Abstract
Introduction Early‐onset colorectal cancer (EO‐CRC) is a public health concern. Starting screening at 45 years has been considered, but there is discrepancy in the recommendations. Racial disparities in EO‐CRC incidence and survival are reported; however, racial/ethnic differences in EO‐CRC features that could inform a racial/ethnic‐tailored CRC screening strategy have not been reported. We compared features and survival among Non‐Hispanic White (NHW), Non‐Hispanic Black (NHB), and Hispanics with EO‐CRC. Methods CRC patients from SEER 1973–2010 database were identified, and EO‐CRC was defined as CRC at <50 years. Clinical/pathological features and survival were compared between NHW, NHB, and Hispanics. Cancer‐specific survival (CSS) predictors were assessed in a multivariable Cox proportional hazard model. Results Of 166,416 patients with CRC, 16,545 (9.9%) had EO‐CRC. The EO‐CRC frequencies in NHB and Hispanics were higher than NHW (12.7% vs. 16.5% vs. 8.7%, p < 0.001). EO‐CRC in NHB presents more frequently in females, with well/moderately differentiated, stage IV, and is less likely to present in locations targetable by sigmoidoscopy than NHW (54.6% vs. 67.7% OR:1.7, 95% p < 0.001). 5‐year CSS was lower in NHB (59.4% vs. 72.8%, HR: 1.7; 95% CI: 1.54–1.82) and Hispanics (66.4% vs. 72.8%, HR: 1.3; 95% CI: 1.16–1.39) than NHW. A regression model among patients with EO‐CRC showed that being NHB or Hispanic were independent predictors for cancer‐specific mortality, after adjusting for gender, grade, stage, and surgery. Conclusion EO‐CRC is more likely in NHB and Hispanics. Racial disparities in clinical/pathological features and CSS between NHB and NHW/Hispanics were evidenced. A racial/ethnic specific screening strategy could be considered as an alternative for patients younger than 50 years.

Abstract
BACKGROUND The ideal depth of general anesthesia should achieve the required levels of hypnosis, analgesia, and muscle relaxation while minimizing physiologic responses to awareness. The choice of anesthetic strategy in patients with coronary heart disease (CHD) undergoing major noncardiac surgery is becoming an increasingly important issue as the population ages. This is because general anesthesia is associated with a risk of perioperative cardiac complications and death, and this risk is much higher in people with CHD.
AIM To compare hemodynamic function and cardiovascular event rate between etomidate- and propofol-based anesthesia in patients with CHD.
METHODS This prospective study enrolled consecutive patients (American Society of Anesthesiologists grade II/III) with stable CHD (New York Heart Association class I/II) undergoing major noncardiac surgery. The patients were randomly allocated to receive either etomidate/remifentanil-based or propofol/remifentanil-based general anesthesia. Randomization was performed using a computer-generated random number table and sequentially numbered, opaque, sealed envelopes. Concealment was maintained until the patient had arrived in the operating theater, at which point the consulting anesthetist opened the envelope. All patients, data collectors, and data analyzers were blinded to the type of anesthesia used. The primary endpoints were the occurrence of cardiovascular events (bradycardia, tachycardia, hypotension, ST-T segment changes, and ventricular premature beats) during anesthesia and cardiac troponin I level at 24 h. The secondary endpoints were hemodynamic parameters, bispectral index, and use of vasopressors during anesthesia.
RESULTS The final analysis included 40 patients in each of the propofol and etomidate groups. The incidences of bradycardia, hypotension, ST-T segment changes, and ventricular premature beats during anesthesia were significantly higher in the propofol group than in the etomidate group (P < 0.05 for all). The incidence of tachycardia was similar between the two groups. Cardiac troponin I levels were comparable between the two groups both before the induction of anesthesia and at 24 h after surgery. When compared with the etomidate group, the propofol group had significantly lower heart rates at 3 min after the anesthetic was injected (T1) and immediately after tracheal intubation (T2), lower systolic blood pressure at T1, and lower diastolic blood pressure and mean arterial pressure at T1, T2, 3 min after tracheal intubation, and 5 min after tracheal intubation (P < 0.05 for all). Vasopressor use was significantly more in the propofol group than in the etomidate group during the induction and maintenance periods (P < 0.001).
CONCLUSION In patients with CHD undergoing noncardiac major surgery, etomidate-based anesthesia is associated with fewer cardiovascular events and smaller hemodynamic changes than propofol-based anesthesia.

Abstract
(2S, 3R)-4-methylsulfonylphenylserine [(2S, 3R)-MPS], a key chiral precursor for antibiotics florfenicol and thiamphenicol, could be asymmetrically synthesized by l-threonine transaldolase (LTTA) coupled with an acetaldehyde elimination system. The low efficiency of acetaldehyde elimination system blocked further accumulation of (2S, 3R)-MPS. To address this issue, strengthening acetaldehyde elimination system and enzyme self-assembly strategy were combined to accelerate biosynthesis of (2S, 3R)-MPS. The new multi-enzyme cascade with intensified acetaldehyde elimination system BL21 (PsLTTAD2/ScADH/BtGDH) could produce (2S, 3R)-MPS with a titer of 157.6 mM, 1.7-folds than that produced by the original system BL21 (PsLTTAD2/ApADH/CbFDH). Moreover, self-assembly of PsLTTAD2 and ScADH by respective fusion of SpyTag and SpyCatcher were carried out to develop a self-assembled multi-enzyme cascade BL21 (ST-PsLTTAD2/SC-ScADH/BtGDH). As a result, the yield of (2S, 3R)-MPS was up to 248.1 mM with 95% de. As far as we knew, that represented the highest yield of (2S, 3R)-MPS by enzymatic synthesis, and therefore was a promising and green route for industrial production of this valuable compound.

Abstract
Abstract
Background: The Oncotype DX 21-gene expression assay (ODX) is prognostic for recurrence and predictive of chemotherapy benefit in early estrogen receptor-positive (ER+) HER2-negative (HER2-) breast cancer (BCA). Invasive ductal carcinoma (IDC) comprises approximately 80% of BCA. Invasive lobular carcinoma (ILC) is a subtype of BCA with distinct pathologic features, and often has low to intermediate ODX Recurrence Score (RS). We evaluated differences in clinicopathologic characteristics, RS and chemotherapy benefit between IDC, ILC, and carcinomas of mixed histologies (ductal + lobular (DLC), ductal + other (DOC), and lobular + other (LOC)) in the National Cancer Database (NCDB). Methods: Female patients (pts) diagnosed between 1/1/2010 and 1/1/2014 with ER+ HER2- BCA, measuring up to 5 cm, with 0-3 involved axillary lymph nodes (LN), treated with definitive surgery as first treatment, and with numeric ODX recurrence score (RS) available were identified from the 2005-2016 NCDB database. Associations between categorical variables were examined using the chi-square test. The Cox proportional hazards model was used to examine the difference in overall survival between histology subtypes while controlling for age, race/ethnicity, RS, tumor size, grade, LN involvement and treatment. Results: 77,472 pts met inclusion criteria, 62,395 (83.8%) node negative (N0) and 12,077 (16.2%) node positive (N+). 57,615 pts (77.4%) had IDC; 8693 (11.7%) ILC; 5393 (7.2%) DLC; 2457 (3.3%) DOC; and 312 (0.4%) LOC. DOC and LOC were more common in Black than White pts (p<0.0001). IDC was associated with smaller tumor size and high grade disease. ILC was associated with larger tumor size, and was least likely to be high grade (p<0.0001). IDC was most likely to have high RS >26. Presence of lobular histology (ILC, DLC and LOC) was associated with lower incidence of RS >26. ILC was least likely to have both low RS (0-10) and high RS (p<0.0001). Pts with IDC were more likely to receive adjuvant chemotherapy (27.4%) than pts with other BCA types (ILC 19.3%; DLC 21.9%; DOC 20.5%; LOC 19.2%, p<0.0001). Overall survival (OS) for IDC, ILC and DOC were similar. DLC was associated with improved OS compared with IDC (HR 0.82, p=0.02). Receipt of adjuvant chemotherapy was associated with improved OS in IDC (HR=0.76, p<0.0001) but not in ILC (HR=0.99, p=0.93), DLC (HR=1.04, p=0.86), DOC (HR=0.87, p=0.71), or LOC (HR=2.91, p=0.10). Conclusion: Lobular and mixed BCA histologies have distinct clinicopathologic features compared with IDC, and are less likely to have high RS. OS is similar for early IDC and ILC. Chemotherapy benefit was not seen in ILC or mixed BCA histologies.

Abstract
Abstract
Purpose: To comparing the survival in different strategies, preoperative systemic treatment (PST) versus upfront surgery (US) in patients of HER2-positive early breast cancer in real-world.Methods: Eligible patients from 2012 to 2015 were classified as PST or US group prospectively, according to the real upfront treatment. The primary endpoint is disease-free survival (DFS), the second endpoint is overall survival (OS). All the outcomes were examined in unadjusted model, propensity score matching (PSM) model, and inverse probability of treatment weighting (IPTW) model. Results: Finally, 1067 eligible patients (215 in PST group, 852 in US group) were included into analysis (Table 1). In unweighted analysis, the cumulative DFS of PST group was significantly lower than US group (78.1% vs 87.7%, P<0.001), especially for those did not reach pathological complete response after PST. After adjusting the parameters, in PSM model (matching at 1:1 ratio), the DFS of PST group was significantly higher than the DFS of US group (HR, 0.57s2, 95%CI, 0.371~0.881, P, 0.012). In IPTW model, there was no significant difference of DFS between two groups (HR, 0.946, 95%CI, 0.763~1.172, P, 0.609). For OS, there were no significant difference between two groups in all three models. Conclusions: The patients in PST group have worse DFS than those in US group, mainly because of the unbalancing stage and biological risk. By real-world statistic method, after adjusting and making parameters comparable, the DFS of PST group is non-inferiority to the DFS of US group in IPTW model and even superior to US group in PSM model.

In further stratified analysis (Figure 3E, 3F), as in PSM model, the DFS and OS rate of the patients without pCR after PST (73.1%, 88.4%) were worse than those with pCR (96.6%, 99.3%) and US group (80.8%, 90.3%), respectively.

Abstract
Plant CaCA superfamily genes with higher tendency to retain after WGD are more gene expression and function differentiated in ion-response. Plants and animals face different environmental stresses but share conserved Ca2+ signaling pathways, such as Ca2+/Cation transport. The Ca2+/cation antiporters superfamily (CaCAs) is an ancient and widespread family of ion-coupled cation transporters found in all kingdoms of life. We analyzed the molecular evolution progress of the family through comparative genomics and phylogenetics of CaCAs genes from plants and animals, grouping these genes into several families and clades, and identified multiple gene duplication retention events, particularly in the CAX (H+/cation exchanger), CCX (cation/Ca2+ exchanger), and NCL (Na+/Ca2+ exchanger-like) families. The tendency of duplication retention differs between families and gene clades. The gene duplication events were probably the result of whole-genome duplication (WGD) in plants and might have led to functional divergence. Tissue and ion-response expression analyses revealed that CaCAs genes with more highly differentiated expression patterns are more likely to be retained as duplicates than those with more conserved expression profiles. Phenotype of Arabidopsis thaliana mutants showed that loss of genes with a greater tendency to be retained after duplication resulted in more severe growth deficiency. CaCAs genes in salt-tolerant species tended to inherit the expression characteristics of their most recent common ancestral genes, with conservative ion-response expression. This study indicates a possible evolutionary scheme for cation transport and illustrates distinct fates and a mechanism for the evolution of gene duplicates. The increased copy numbers of genes and divergences in expression might have contributed to the divergent functions of CaCAs protein, allowing plants to cope with environmental stresses and adapt to a larger number of ecological niches.

Abstract
OBJECTIVE Fibrinogen has been implicated to play a role in the pathophysiology of obstructive sleep apnea (OSA). Many studies have evaluated the effect of continuous positive airway pressure (CPAP) on plasma fibrinogen levels in OSA patients. However, results from different reports were not consistent. To assess the effect of CPAP treatment on plasma fibrinogen levels of patients with OSA, a meta-analysis was performed. METHODS A systematic search of Pubmed, Embase, Cochrane, Wanfang Database and Chinese National Knowledge Infrastructure was performed. Data were extracted, and then weighted mean difference (WMD) and 95% confidence intervals (CIs) were calculated using a random-effects model. RESULTS Twenty-two studies involving 859 patients were included in this meta-analysis. Combined data showed that plasma fibrinogen concentrations decreased after CPAP therapy (WMD = -0.38 g/l, 95% CI [-0.54 to -0.22 g/l], P<0.001). In the subgroup analyses by therapy duration, plasma fibrinogen concentrations declined significantly in the long-term (≥1 month) CPAP therapy subgroup (WMD = -0.33 g/l, 95% CI [-0.49 to -0.16 g/l], P<0.001) but not in the short-term (<1 month) CPAP therapy subgroup (WMD = -0.84 g/l, 95% CI [-1.70 to 0.03 g/l], P=0.058). Moreover, in patients with long-term CPAP therapy duration, plasma fibrinogen levels decreased with good CPAP compliance (≥4 h/night) (WMD = -0.37 g/l, 95% CI [-0.55 to -0.19 g/l], P<0.001) but not with poor CPAP compliance (<4 h/night) (WMD = 0.12 g/l, 95% CI [-0.09 to 0.33 g/l], P=0.247). CONCLUSION Long-term CPAP treatment with good compliance can reduce the plasma fibrinogen levels in patients with OSA.

Abstract
Alginate lyases have been widely used for the preparation of bioactive alginate oligosaccharides. An alginate lyase AlgL-CD was rationally designed by introducing alkaline amino acid residues near active center to increase activity. One of its mutants E226K presented much higher activity than wild-type AlgL-CD. Substrate affinity of E226K increased 10 folds as the Km values indicated. The spectra of intrinsic emission fluorescence and circular dichroism of E226K suggested the whole enzyme turned to be more flexible. The 8-anilino-1-naphthalenesulfonate (ANS)-binding assay showed that the hydrophobic active center of E226K was more available to ligand. Molecular dynamic analysis of the enzyme-substrate complex showed that lid loops of the active center in E226K turned to be more opened up, which might contribute to the increase of substrate-binding affinity. Meanwhile, the catalytic residue of E226K was closer to the hydrogen donor C5 atom of the substrate to increase catalysis rate. The final degradation products of alginate by E226K were determined to be identical with that of AlgL-CD. This study provides guidance for improving enzymatic preparation efficiency of bioactive alginate oligosaccharides.

Abstract
BACKGROUND Non-Hispanic blacks (NHB) with renal cell carcinoma (RCC) are more likely to have papillary RCC (pRCC) than non-Hispanic whites (NHW). Data on histologic subtypes in RCC in Hispanics (H) are also sparse. Previous studies have shown that pRCC is more prevalent in NHB than in NHW, but they analyzed predominantly NHW populations. The Montefiore-Einstein Center for Cancer Care (MECC) serves a predominantly NHB and H population in the Bronx, NY. We investigated histologic subtype specific associations with established RCC risk factors in this population. PATIENTS AND METHODS The MECC tumor registry was used to identify patients ≥ 18 years of age treated with partial or radical nephrectomy between January 2000 and December 2015. An institutional software program and individual chart review were used to obtain demographic data (including self-reported race, age, and sex), pathology data, and RCC risk factors (hypertension, diabetes, renal function, weight). Data were modeled by multinomial logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS A total of 1010 RCC cases were identified. Of these, 232 (23.0%) occurred in NHW, 383 (37.9%) NHB, 181 (17.9%) H, and 214 (21.2%) other. A total of 530 cases (52.5%) were clear cell (ccRCC) histology, 257 (25.4%) pRCC, 100 (9.9%) chromophobe (cRCC), and 123 (12.2%) other. Individuals with pRCC compared to ccRCC were more likely to be NHB than NHW (OR, 4.41; 95% CI, 2.81-6.93) but were less likely to be female (OR, 0.50; 95% CI, 0.35-0.72). Individuals with pRCC were also less likely to be H than NHW (OR, 0.52; 95% CI, 0.27-0.99). Patients with cRCC were also more likely to be NHB than NHW (OR, 2.23; 95% CI, 1.06-4.67). CONCLUSION In the MECC data set, histology of RCC varies by race, confirming earlier reports that non-ccRCC is more common in NHB than NHW. We also report that pRCC is less common in H than NHW.

Abstract
Copolymerization of 1,3-butadiene with various types of phenyl substituted 1,3-butadiene derivatives, including (E)-1-phenyl-1,3-butadiene (PBD), 1-phenethyl-1,3-butadiene (PEBD), 1-(4-methoxylphenyl)-1,3-butadiene (p-MEPBD), 1-(2-methoxylphenyl)-1,3-butadiene (o-MEPBD) and 1-(4-N,N-dimethylaminophenyl)-1,3-butadiene (p-DMPBD), by using a coordination polymerization system of CpTiCl3/MAO is reported herein. Comonomers PBD and PEBD can be copolymerized with 1,3-butadiene in a large range of comonomer feed ratios (0–44.6% for PBD, 0–30.2% for PEBD), affording the targeted copolymers with well-controlled comonomer incorporations, molecular weights, polydispersities and microstructure, whereas no corresponding copolymer products were obtained under identical conditions when p-MEPBD, o-MEPBD and p-DMPBD were employed. Moreover, different polymerization parameters, including temperature, Al/Ti ratio, etc., posed a significant influence on the polymerization behaviors, as well as the properties of the resultant copolymers. Microstructure analysis by NMR spectra revealed high 1,4-selectivities of the catalysts, and the glass transition temperature (Tg) of the resulted copolymer was found to be highly dependent on the incorporation content of the comonomers; with an increasing comonomer content, a gradually increasing Tg was demonstrated. Copolymerization of 1,3-butadiene with various phenyl substituted 1,3-butadiene derivatives to access pendant phenyl functionalized polydiene elastomers is reported.![]()

Abstract
Lanthanum-modified bentonite (LMB, Phoslock®) is a well-known capping agent for phosphorus immobilization in sediments. Herein, LMB was used to immobilize As in sediments. Batch capacity experiments for arsenate and arsenite adsorption were carried out to obtain adsorption isotherms and kinetics using the Langmuir and Freundlich model calculations. High-resolution (HR) diffusive gradients in thin films (DGT) were applied to monitor the changes of weakly bound As fraction near sediment-water interface (SWI). The interaction of As(III) and As(V) with LMB was influenced by pH and initial mineral composition. As(V) was more obviously adsorbed than As(III) at pH 4 to 9, with mean adsorption of 3.89 mg g-1 and 0.04 mg g-1, respectively, while at pH > 9 As(III) was preferentially adsorbed. After LMB amendment for 2 months, the maximum As removal efficiency in the pore and overlying water reached 84.5% and 99.3%, respectively. The capping agent remained stable in the top sediments, while the maximum DGT labile As content decreased to 0.89 and 0.51 μg L-1 in dosage-and time-treatments. The As concentration inflection point moved down to a deeper layer. As species changed from labile exchangeable-As to Fe-oxide-bound and residual As. The proportion of mobile As finally decreased to 10.5% of the total As in the upper 20-mm layer sediment. The increase of Kd (the distribution coefficient at SWI) and k1 (adsorption rate constant) and the decrease of Tc (response time of (de)sorption) in the DGT-induced fluxes model (DIFS) indicated the time-dependent impediment of As release from the sediment due to LMB immobilization.

Abstract
PURPOSE To evaluate the association between the CT rim sign and gangrenous cholecystitis (GC) and increased surgical difficulty. METHOD Patients who had a contrast enhanced CT of the abdomen and pelvis, followed by non-elective cholecystectomy were analyzed. The scans were reviewed for the CT rim sign by radiologists blinded to the pathologic and clinical outcomes. Demographic and clinical characteristics were compared between patients with and without GC using t-tests or Wilcoxon ranked sum test for continuous variables, and Fishers' exact test for categorical variables, when appropriate. A logistic regression model was fitted with multiple risk factors. Odds ratios as well as 95% confidence intervals were then calculated for the risk factors. A secondary analysis predicting increased surgical difficulty, defined as an operative time of greater than 2 h or increased conversion rate to open surgery, was also examined. RESULTS A total of 100 patients were included; 20 of which had GC. On imaging, patients with GC were more likely to have a CT rim sign (65% vs 32.5%, OR = 3.80, 95% CI: 1.24-12.7, p = 0.011). The presence of the CT rim sign did not reach a statistically significant association with an operative time >2 h or conversion to open case (56.52% vs 33.77%, OR = 2.55, p = 0.056). CONCLUSION The CT rim sign can be utilized to raise the possibility of GC, however the presence of the CT rim sign does not demonstrate an association with increased surgical difficulty.

Abstract
BACKGROUND The Cancer Genome Atlas identified four molecular subgroups of endometrial cancer with survival differences based on whole genome, transcriptomic, and proteomic characterization. Clinically accessible algorithms that reproduce this data are needed. Our aim was to determine if targeted sequencing alone allowed for molecular classification of endometrial cancer. METHODS Using a custom-designed 156 gene panel, we analyzed 47 endometrial cancers and matching non-tumor tissue. Variants were annotated for pathogenicity and medical records were reviewed for the clinicopathologic variables. Using molecular characteristics, tumors were classified into four subgroups. Group 1 included patients with > 570 unfiltered somatic variants, > 9 cytosine to adenine nucleotide substitutions per sample, and < 1 cytosine to guanine nucleotide substitution per sample. Group 2 included patients with any somatic mutation in MSH2, MSH6, MLH1, PMS2. Group 3 included patients with TP53 mutations without mutation in mismatch repair genes. Remaining patients were classified as group 4. Analyses were performed using SAS 9.4 (SAS Institute Inc., Cary, North Carolina, USA). RESULTS Endometrioid endometrial cancers had more candidate variants of potential pathogenic interest (median 6 IQR 4.13 vs. 2 IQR 2.3; p < 0.01) than uterine serous cancers. PTEN (82% vs. 15%, p < 0.01) and PIK3CA (74% vs. 23%, p < 0.01) mutations were more frequent in endometrioid than serous carcinomas. TP53 (18% vs. 77%, p < 0.01) mutations were more frequent in serous carcinomas. Visual inspection of the number of unfiltered somatic variants per sample identified six grade 3 endometrioid samples with high tumor mutational burden, all of which demonstrated POLE mutations, most commonly P286R and V411L. Of the grade 3 endometrioid carcinomas, those with POLE mutations were less likely to have risk factors necessitating adjuvant treatment than those with low tumor mutational burden. Targeted sequencing was unable to assign samples to microsatellite unstable, copy number low, and copy number high subgroups. CONCLUSIONS Targeted sequencing can predict the presence of POLE mutations based on the tumor mutational burden. However, targeted sequencing alone is inadequate to classify endometrial cancers into molecular subgroups identified by The Cancer Genome Atlas.

Abstract
BACKGROUND Compared to traditional open surgery, laparoscopic surgery has become a standard approach for colorectal cancer due to its great superiorities including less postoperative pain, a shorter hospital stay, and better quality of life. In 2007, Whiteford et al reported the first natural orifice trans-anal endoscopic surgery (NOTES) sigmoidectomy using transanal endoscopic microsurgery. To date, all cases of NOTES colorectal resection have included a hybrid laparoscopic approach with the use of established rigid platforms.
AIM To introduce a novel technique of peroral external traction-assisted transanal NOTES rectosigmoidectomy followed by intracorporeal colorectal end-to-end anastomosis by using only currently available and flexible endoscopic instrumentation in a live porcine model.
METHODS Three female pigs weighing 25-30 kg underwent NOTES rectosigmoid resection. After preoperative work-up and bowel preparation, general anesthesia combined with endotracheal intubation was achieved. One dual-channel therapeutic endoscope was used. Carbon dioxide insufflation was performed during the operation. The procedure of trans-anal NOTES rectosigmoidectomy included the following eight steps: (1) The rectosigmoid colon was tattooed with India ink by submucosal injection; (2) Creation of gastrostomy by directed submucosal tunneling; (3) Peroral external traction using endoloop ligation; (4) Creation of rectostomy on the anterior rectal wall by directed 3 cm submucosal tunneling; (5) Peroral external traction-assisted dissection of the left side of the colon; (6) Trans-anal rectosigmoid specimen transection, where an anvil was inserted into the proximal segment after purse-string suturing; (7) Intracorporeal colorectal end-to-end anastomosis using a circular stapler by a single stapling technique; and (8) Closure of gastrostomy using endoscopic clips. All animals were euthanized immediately after the procedure, abdominal exploration was performed, and the air-under-water leak test was carried out.
RESULTS The procedure was completed in all three animals, with the operation time ranging from 193 min to 259 min. Neither major intraoperative complications nor hemodynamic instability occurred during the operation. The length of the resected specimen ranged from 7 cm to 13 cm. With the assistance of a trans-umbilical rigid grasper, intracorporeal colorectal, tension-free, end-to-end anastomosis was achieved in the three animals.
CONCLUSION Peroral traction-assisted transanal NOTES rectosigmoidectomy followed by intracorporeal colorectal end-to-end anastomosis is technically feasible and reproducible in an animal model and is worthy of further improvements.

Abstract
AIMS Oily sludge is a kind of mixture that is extremely harmful to the environment. Anaerobic digestion (AD) is a commonly used method for biodegrading oily sludge. However, the AD treatment cycle is usually long and inefficient. Here, we developed an approach to improve the degradation rate of oily sludge by integrating subcritical hydrothermal pretreatment (SHP) and AD. METHODS AND RESULTS First, using SHP, the hydrocarbon compounds with long carbon chains that make up oil sludge were decomposed into hydrocarbons with short carbon chains, which are conducive to microbial decomposition and transformation. Then, AD was performed using a variety of temperature and solid-liquid ratio parameters. The results showed that the degradation ratio of oily sludge was higher when SHP was combined with AD than when no pre-treatment was performed. Optimal degradation was reached by performing SHP to obtain CHS8, then performing AD at 30°C using a 1:5 solid-liquid ratio. Under these conditions, maximum degradation ratios of 69·00% of TOC, 59·02% of COD, 44·68% of ammonia and 54·24% of oil content were reached. CONCLUSIONS In conclusion, after SHP with 8% dilute sulphuric acid, most of the macromolecular hydrocarbons in the oily sludge were converted into smaller molecules, which facilitated subsequent microbial decomposition. The results showed that this combination of SHP and AD processes promotes more efficient degradation than a conventional single AD process without any hydrothermal pretreatment. SIGNIFICANCE AND IMPACT OF THE STUDY Our experiments provide technical support for enhancing the rapid degradation of oily sludge.

Abstract
Multisystem inflammatory syndrome in children is a recently described complication in the late phase of Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) infection involving systemic hyperinflammation and multiorgan dysfunction. The extent of its clinical picture is actively evolving and has yet to be fully elucidated. While neurologic manifestations of SARS-CoV-2 are well-described in the adult population, reports of neurologic complications in pediatric patients with SARS-CoV-2 infection are limited. We present a pediatric patient with SARS-CoV-2 infection with development of multisystem inflammatory syndrome and acute encephalopathy causing delirium who was found to have a cytotoxic lesion of the corpus callosum on neuroimaging. Cytotoxic lesions of the corpus callosum are a well-known, typically reversible entity that can occur in a wide range of conditions, including infection, seizure, toxins, nutritional deficiencies, and Kawasaki disease. We hypothesized that the cytotoxic lesion of the corpus callosum, in the index case, was secondary to the systemic inflammation from SARS-CoV-2 infection, resulting in multisystem inflammatory syndrome in children.

Abstract
Abstract
Introduction/Objective
Variable histologic findings that may be seen in porto-sinusoidal vascular disease (PSVD) liver biopsies are subject to high interobserver variability, requiring correlation with clinical history of portal hypertension (traditionally interpreted as non-cirrhotic portal hypertension NCPH). We investigated which histologic features are reproducible in PSVD biopsies.
Methods
Archived liver biopsies (n=38) from patients with NCPH (n=14) and without NCPH (n=21) were reviewed. Static H&E images of lobules (L, x100, NCPH=27, non-NCPH=23) and portal tracts (P, x200, NCPH=23, non- NCPH=27) were distributed among 9 gastrointestinal pathologists blinded to clinical history. Each pathologist answered multiple choice questions based on the presence (Q2) or absence (Q1) of portal hypertension clinically. The choice selected by 6 pathologists or more was considered consensus answer for the image. The interpretation of the image was considered reproducible when consensus was reached on both Q1 and Q2.
Results
The interpretations of 27 (54%; 17L, 10P) images from NCPH and 21 (42%; 10L, 11P) from non-NCPH were reproducible. In NCPH, the interpretations of normal (n=10, 4L, 6P), sinusoidal dilatation (n=7), and increased parenchymal draining vessels (n=3) were reproducible, while there was no consensus on the diagnoses of nodular regeneration and increased number of portal vessels. In non-NCPH, the interpretations of normal (n=8, 2L, 6P), sinusoidal dilatation (n=6), and paraportal shunting vessel(s) (n=4) were reproducible, whereas no consensus was reached on the diagnoses of nodular regeneration, incomplete fibrous septa, and increased number of portal vessels.
Conclusion
Histologic assessment of normal L and P as well as sinusoidal dilatation appears to be reproducible independent of clinical history. The findings of increased parenchymal draining vessels in NCPH group and paraportal shunting vessels in non-NCPH group may be consistently diagnosed to a certain extent. The assessment for nodular regeneration without reticulin stain, incomplete fibrous septa, or increased number of portal vessels appears to be unreliable.

Abstract
OBJECTIVE Mutations in phosphatase and tensin homologue deleted on chromosome 10 (PTEN), a tumor suppressor gene, lead to altered sensitivity to drugs and radiation in various types of cancer. Restoring PTEN expression in tumor cells can increase radiosensitivity by inhibiting the repair of DNA double-strand breaks (DSBs). Thus, determining the mechanism of action of this protein may lead to novel therapeutic strategies. MATERIALS AND METHODS In this study, we transduced U251 cells with a lentiviral vector expressing PTEN to examine the mechanism of radiosensitization. Specifically, we examined the formation of radiation-induced DNA DSBs and apoptosis, as well as the expression of several proteins involved in repairing DSBs (p53, ataxia-telangiectasia mutated, DNA-dependent protein kinase C, Ku70-80). RESULTS Our results showed that PTEN transduction sensitized U251 cells to X-rays, increasing the number of DSBs per cell and fraction of cells undergoing apoptosis. Additionally, the average size of γH2AX nuclear foci was increased following irradiation. These findings were accompanied by a PTEN-dependent irradiation-independent increase in p53 levels and decrease in phosphorylated Ku70/80 levels. CONCLUSIONS Our results suggest that PTEN affects radiosensitivity by reducing DSB repair and by enhancing the p53 pathway, leading to increased apoptosis.

Abstract
OBJECTIVE To investigate the nurses' attitude towards open visitation policy in intensive care unit (ICU) and its potential influence factors, and further to provide evidence for carrying out this policy in ICU. METHODS A self-designed, anonymous online questionnaire of "attitude of ICU nurses to open visiting system in ICU" was performed in 31 provinces, autonomous regions and municipalities in China from October to December 2019, using convenient sampling method approach. Only nurses working in ICU (including specialized ICU, but excluding the critical ward in general ward) and willing to participate in the survey were included. The survey included 35 items, including the general information of each participant, the attitude towards the implementation of the open visitation system in ICU and its potential influencing factors. Ordinal Logistic regression analysis was used to identify the significant influencing factors. RESULTS A total of 1 558 questionnaires were sent out and 1 546 effective questionnaires were retrieved, with a response rate of 99.2%. Overall, 32.2% of them agreed with the policy, 41.3% of them disagree with the policy and 26.5% of them were uncertain. The Ordinal Logistic regression analysis showed that the independent influencing factors of ICU nurses' attitude towards open visitation policy including the possibility of increasing healthcare-associated infection [disagree: β = 1.327, 95% confidence interval (95%CI) was 0.242 to 2.413, P = 0.017; uncertain: β = 0.697, 95%CI was 0.244 to 1.151, P = 0.003], the improvement of nurses' job satisfaction (disagree: β = -1.406, 95%CI was -1.750 to -1.062, P = 0.000; uncertain: β = -0.748, 95%CI was -1.030 to -0.466, P = 0.000), the information support for medical staffs from family members (disagree: β = -0.644, 95%CI was -1.048 to -0.240, P = 0.002; uncertain: β = -0.422, 95%CI was -0.721 to -0.124, P = 0.006), the feasibility that the family members can assist the nurses in the basic nursing for patients (uncertain: β = -0.465, 95%CI was -0.729 to -0.202, P = 0.001), reducing the time that a nurse spent on caring for the patients (uncertain: β = 0.349, 95%CI was 0.052 to 0.646, P = 0.021), improving early rehabilitation (disagree: β = -0.593, 95%CI was -1.166 to -0.019, P = 0.043), and getting psychological support for patients from family members (disagree: β = 1.293, 95%CI was 0.426 to 2.159, P = 0.003), family members' satisfaction (disagree: β = -0.981, 95%CI was -1.431 to -0.531, P = 0.000). CONCLUSIONS ICU nurses in China have realized that open visitation policy has positive effect on patients' early rehabilitation, willing to live and satisfaction; meanwhile, this policy may need more improvement in many ways such as healthcare-associated infection control, disinfection and isolation, allocation of human resources and time spent treating and caring for patients.
