Abstract
Ambient electrochemical ammonia (NH3 ) synthesis is one promising alternative to the energy-intensive Haber-Bosch route. However, the industrial requirement for the electrochemical NH3 production with amperes current densities or gram-level NH3 yield remains a grand challenge. Herein, we report the high-rate NH3 production via NO2 - reduction using the Cu activated Co electrode in a bipolar membrane (BPM) assemble electrolyser, wherein BPM maintains the ion balance and the liquid level of electrolyte. Benefited from the abundant Co sites and optimal structure, the target modified Co foam electrode delivers a current density of 2.64 A cm-2 with the Faradaic efficiency of 96.45 % and the high NH3 yield rate of 279.44 mg h-1 cm-2 in H-type cell using alkaline electrolyte. Combined with in situ experiments and theoretical calculations, we found that Cu optimizes the adsorption behavior of NO2 - and facilitates the hydrogenation steps on Co sites toward a rapid NO2 - reduction process. Importantly, this activated Co electrode affords a large NH3 production up to 4.11 g h-1 in a homemade reactor, highlighting its large-scale practical feasibility.

Abstract
Ammonia (NH3 ) is essential for modern agriculture and industry, and, due to its high hydrogen density and no carbon emission, it is also expected to be the next-generation of "clean" energy carrier. Herein, directly from air and water, a plasma-electrocatalytic reaction system for NH3 production, which combines two steps of plasma-air-to-NOx - and electrochemical NOx - reduction reaction (eNOx RR) with a bifunctional catalyst, is successfully established. Especially, the bifunctional catalyst of CuCo2 O4 /Ni can simultaneously promote plasma-air-to-NOx - and eNOx RR processes. The easy adsorption and activation of O2 by CuCo2 O4 /Ni greatly improve the NOx - production rate at the first step. Further, CuCo2 O4 /Ni can also resolve the overbonding of the key intermediate of * NO, and thus reduce the energy barrier of the second step of eNOx RR. Finally, the "green" NH3 production achieves excellent FENH3 (96.8%) and record-high NH3 yield rate of 145.8 mg h-1 cm-2 with large partial current density (1384.7 mA cm-2 ). Moreover, an enlarged self-made H-type electrolyzer improves the NH3 yield to 3.6 g h-1 , and the obtained NH3 is then rapidly converted to a solid of magnesium ammonium phosphate hexahydrate, which favors the easy storage and transportation of NH3 .

Abstract
In recent years, the manipulation of structured optical beam has become an attractive and promising area. The Gaussian beam is the most common beam as the output beam of the laser, and the Airy beam is recently proposed with fascinating properties and applications. In this paper, for the first time to our knowledge, the polarization is used as a tool to design a new kind of Airy-Gaussian vector beam by connecting the Gaussian and Airy functions, which opens a new avenue in designing new beams based on the existed beams. We realize the Airy-Gaussian vector beam with space-variant polarization distribution in theory and experiment, and find that the vector beam can autofocus twice during propagation. The optical chains with flexible intensity peaks are achieved with the Airy-Gaussian vector beam, which can be applied in trapping and delivering particles including biological cells and Rydberg atoms. Such optical chains can significantly improve the trapping efficiency, reduce the heat accumulation, and sweep away the impurity particles.

Abstract
Damage to peritubular capillaries is a key process that contributes to acute kidney injury (AKI) progression. Vascular endothelial growth factor A (VEGFA) plays a critical role in maintaining the renal microvasculature. However, the physiological role of VEGFA in various AKI durations remains unclear. A severe unilateral ischemia‒reperfusion injury model was established to provide an overview of VEGFA expression and the peritubular microvascular density from acute to chronic injury in mouse kidneys. Therapeutic strategies involving early VEGFA supplementation protecting against acute injury and late anti-VEGFA treatment for fibrosis alleviation were analyzed. A proteomic analysis was conducted to determine the potential mechanism of renal fibrosis alleviation by anti-VEGFA. The results showed that two peaks of extraglomerular VEGFA expression were observed during AKI progression: one occurred at the early phase of AKI, and the other occurred during the transition to chronic kidney disease (CKD). Capillary rarefaction progressed despite the high expression of VEGFA at the CKD stage, and VEGFA was associated with interstitial fibrosis. Early VEGFA supplementation protected against renal injury by preserving microvessel structures and counteracting secondary tubular hypoxic insults, whereas late anti-VEGFA treatment attenuated renal fibrosis progression. The proteomic analysis highlighted an array of biological processes related to fibrosis alleviation by anti-VEGFA, which included regulation of supramolecular fiber organization, cell-matrix adhesion, fibroblast migration, and vasculogenesis. These findings establish the landscape of VEGFA expression and its dual roles during AKI progression, which provides the possibility for the orderly regulation of VEGFA to alleviate early acute injury and late fibrosis.

Abstract
BACKGROUND Patients with colorectal liver metastases (CRLM) combined with hepatic lymph node (HLN) metastases have a poor prognosis. In this study, we developed and validated a model using clinical and magnetic resonance imaging (MRI) parameters to predict HLN status before surgery. METHODS A total of 104 CRLM patients undergoing hepatic lymphonodectomy with pathologically confirmed HLN status after preoperative chemotherapy were enrolled in this study. The patients were further divided into a training group (n = 52) and a validation group (n = 52). The apparent diffusion coefficient (ADC) values, including ADCmean and ADCmin of the largest HLN before and after treatment, were measured. rADC was calculated referring to the target liver metastases, spleen, and psoas major muscle (rADC-LM, rADC-SP, rADC-m). In addition, ADC change rate (Δ% ADC) was quantitatively calculated. A multivariate logistic regression model for predicting HLN status in CRLM patients was constructed using the training group and further tested in the validation group. RESULTS In the training cohort, post-ADCmean (P = 0.018) and the short diameter of the largest lymph node after treatment (P = 0.001) were independent predictors for metastatic HLN in CRLM patients. The model's AUC was 0.859 (95% CI, 0.757-0.961) and 0.767 (95% CI 0.634-0.900) in the training and validation cohorts, respectively. Patients with metastatic HLN showed significantly worse overall survival (p = 0.035) and recurrence-free survival (p = 0.015) than patients with negative HLN. CONCLUSIONS The developed model using MRI parameters could accurately predict HLN metastases in CRLM patients and could be used to preoperatively assess the HLN status and facilitate surgical treatment decisions in patients with CRLM.

In this paper, the sampling and monitoring methods of atmospheric 14C around Ningde NPP were presented, and the variations and trends during 2013-2021 were statistically analyzed and comparatively studied with worldwide reported values around NPPs. Meanwhile, the correlation study with the gaseous effluent emission amount from Ningde NPP was analyzed, and the spatial distribution of the atmospheric 14C around Ningde NPP was simulated with the atmospheric release based on the long-term meteorological parameters with the plume diffusion model. It was shown that the average specific activity of atmospheric 14C at each sampling site ranged from 229 to 230 mBq/gC, and the weak evidence of influence on the nearest sampling site from the release of the NPP could be observed. Seasonal variations of 14C specific activity were analyzed, and it was shown that, except for the site 1.7 km from the NPP, the specific activity of the atmospheric 14C was higher in summer and autumn and lower in winter and spring. Besides, it was shown that the excess 14C for long-term monitoring results around the NPP was consistent with the simulated values on the order of magnitude.

Abstract
Objective: To understand the species, distribution, and extent of drug resistance of pathogenic bacteria in patients with liver cirrhosis combined with bacterial infection in a tertiary hospital in Xinjiang. Methods: 1 271 cases with liver cirrhosis combined with infection were analyzed retrospectively for pathogenic bacterial species and drug resistance condition in different bacterial strain. Results: Among the 1 271 cases with liver cirrhosis, 480 were combined with infection, and the infection rate was 37.8%. The majority of infected patients had decompensated cirrhosis (438 cases). Peritoneum (327 cases, 60.8%) was the common infection site, followed by lungs (16.9%). 343 strains of pathogens were isolated from 480 infected cases, of which 289 strains were among the top 10 common distinct bacteria, accounting for 76.5% and 23.5% of Gram-negative and positive bacteria. The first top three strains were Escherichia coli. (33.2%), Klebsiella pneumoniae (11.4%), and Enterococcus faecium (11.1%), and there were differences in the drug resistance rates of each strain. Conclusion: In a tertiary hospital in Xinjiang, patients with decompensated cirrhosis have a high rate of bacterial infection. The pathogenic bacteria are diverse, mainly Gram-negative bacteria; however, the infection rate of Gram-positive bacteria such as Enterococcus is gradually increasing. Additionally, according to the bacterial properties, they are divided into four categories: Enterobacter, Enterococcus, glucose non-fermenting bacteria and Staphylococcus, and it is found that even the same species of bacteria have different drug resistance rates.

Abstract
Optical needle has become a hot research topic in recent years, due to the excellent properties and potential applications. To achieve a sub-diffraction optical needle, there are three common methods including planar diffractive lenses, reflective mirrors or axicons, and high-NA objective lenses with the designed phase or amplitude elements. Here, we propose a new kind of designed phase and amplitude element called the sinusoidal-amplitude binary phase mask (SA-BPM), which modulates the amplitude and phase distributions of the incident vector optical fields (VOFs) simultaneously. Based on Richards-Wolf vector diffraction integral, the corresponding parameters of SA-BPM and the optimal optical needle length are calculated by exhaustive method and genetic algorithm. We further upgrade the SA-BPM by adding a Gaussian function in the amplitude modulation, and design the Gaussian SA-BPM (GSA-BPM). We find that the ultra-long optical needles are achieved with the SA-BPM and GSA-BPM, and the depth of focus of the optical needles are improved by 30%-70% compared with the case of binary phase mask. Such SA-BPM and GSA-BPM we proposed have great potential for manipulation and utilization of the ultra-long optical needles.

Abstract
Objective: To analyse the clinical characteristics and to explore the prognostic factors of acute pulmonary thromboembolism in the elderly. Methods: The medical records of inpatients with acute pulmonary thromboembolism discharged from Peking Union Medical College Hospital from January 1, 2012, to February 1, 2019 were retrospectively reviewed. The eligible patients were divided into elderly group (≥ 60 years old) and non-elderly group (<60 years old). The clinical symptoms, complications, laboratory results, pulmonary embolism severity index (PESI) and mortality were compared between the two groups. Mortality was further compared among elderly patients of different age groups. Cox regression analysis was used to analyze the risk factors of 7-day and 30-day death in elderly patients with pulmonary embolism. Results: A total of 503 patients with acute pulmonary embolism were included, including 279 cases in the elderly group and 224 cases in the non-elderly group. The incidence of cardiac arrest was higher in the elderly group compared with non-elderly group, while the incidence of chest pain and hemoptysis was less common in the elderly group. The proportions of comorbidities, including diabetes, hypertension, and coronary heart disease were higher in the elderly group while the proportion of autoimmune diseases was higher in the non-elderly group. In terms of prognosis, the PESI score and 7-day and 30-day mortality in the elderly group were higher than those in the non-elderly group. The mortality of elderly patients increased with age. Cox univariate regression analysis showed that infection, hypoalbuminemia, hypocalcemia, elevated cardiac troponin(cTnI), elevated N-terminal prohormone of brain natriuretic pepride(NT-proBNP) and PESI grade were associated with 30-day death. Multivariate Cox regression analysis showed that PESI grade and decreased serum calcium concentration were independent risk factors for 7-day death of pulmonary embolism in elderly patients. PESI grade, decreased serum calcium concentration and infection were independent risk factors for 30-day death. Conclusions: The mortality of elderly patients with pulmonary embolism was higher than that of non-elderly patients, and the mortality increased gradually with age. PESI grade, decreased serum calcium concentration and infection were independent risk factors for 30-day death of pulmonary embolism in elderly patients.

Abstract
BACKGROUND The use of endoscopic surgery for treating gastrointestinal stromal tumors (GISTs) between 2 and 5 cm remains controversial considering the potential risk of metastasis and recurrence. Also, surgeons are facing great difficulties and challenges in assessing the malignant potential of 2-5 cm gastric GISTs.
AIM To develop and evaluate computerized tomography (CT)-based radiomics for predicting the malignant potential of primary 2-5 cm gastric GISTs.
METHODS A total of 103 patients with pathologically confirmed gastric GISTs between 2 and 5 cm were enrolled. The malignant potential was categorized into low grade and high grade according to postoperative pathology results. Preoperative CT images were reviewed by two radiologists. A radiological model was constructed by CT findings and clinical characteristics using logistic regression. Radiomic features were extracted from preoperative contrast-enhanced CT images in the arterial phase. The XGboost method was used to construct a radiomics model for the prediction of malignant potential. Nomogram was established by combing the radiomics score with CT findings. All of the models were developed in a training group (n = 69) and evaluated in a test group (n = 34).
RESULTS The area under the curve (AUC) value of the radiological, radiomics, and nomogram models was 0.753 (95% confidence interval [CI]: 0.597-0.909), 0.919 (95%CI: 0.828-1.000), and 0.916 (95%CI: 0.801-1.000) in the training group vs 0.642 (95%CI: 0.379-0.870), 0.881 (95%CI: 0.772-0.990), and 0.894 (95%CI: 0.773-1.000) in the test group, respectively. The AUC of the nomogram model was significantly larger than that of the radiological model in both the training group (Z = 2.795, P = 0.0052) and test group (Z = 2.785, P = 0.0054). The decision curve of analysis showed that the nomogram model produced increased benefit across the entire risk threshold range.
CONCLUSION Radiomics may be an effective tool to predict the malignant potential of 2-5 cm gastric GISTs and assist preoperative clinical decision making.

Abstract
Objective: To summarize the clinicopathological factors related to perinatal fetal death and to evaluate importance of fetal autopsy and placental pathology. Methods: The clinicopathological data of 105 perinatal fetal deaths in Beijing Haidian Maternal and Child Health Hospital from November 2012 to December 2020 were retrospectively analyzed. Relevant literature was also reviewed. Results: The maternal age of the deceased fetuses ranged from 22 to 43 years with the average (31.35±4.04 years), and the gestational weeks were 28-40+6 weeks. Among them, 101 were singleton cases and 4 twin cases. 103 fetuses died in uterus and 2 died during delivery. Relevant factors analysis of the 105 perinatal fetal deaths showed that 86 cases (81.9%, 86/105) were related to umbilical cord/placental abnormality, 10 cases (9.5%, 10/105) uterine infection, 6 cases (5.7%, 6/105) fetal factors, 1 case was fetal maternal blood transfusion syndrome, 1 case twin blood transfusion syndrome, and 1 case died of complete uterine rupture. Among the 86 cases related to umbilical cord/placental abnormality, the diagnosis was most often based on the gross examination of placenta. The most common cause of death was umbilical cord torsion with thin root, followed by placental abruption, tight umbilical cord winding, vascular rupture and umbilical cord true knot. The morphology of placenta revealed mainly functional changes. Among the 10 cases related to intrauterine infections, the placenta generally showed lobular placental edema. The morphological characteristics of ascending infection were mainly acute chorioamnionitis, and the morphological characteristics of blood-borne infection were mainly acute or chronic villitis, as well as villous interstitial inflammation. Identification of viral inclusions suggested viral etiology, while the final diagnosis was relied on laboratory testing. Among the 6 cases related to fetal abnormality, the diagnostic value of placenta was limited and the diagnosis could be made with fetal autopsy. Conclusion: The causes of perinatal fetal death are complex, diverse, and often the synergistic result of multiple factors. Fetal autopsy and placental pathology are the key technical means to identify the cause of death and deserve more attention and utilization.

Abstract
Objective: To detect the incidence and analyze the clinical significance of regions of homozygosity (ROH) through the single nucleotide polymorphism array (SNP array). Methods: The SNP array detection results of 5 116 pregnant women in the Third Affiliated Hospital of Guangzhou Medical University from January 2016 to December 2020 were retrospectively analyzed. The pregnant women with ROH (5 Mb as the threshold) were followed up to analyze the relationship between ROH and abnormal fetal phenotype. Whole exon sequencing was performed in 4 cases of consanguineous marriage to detect potential recessive causative genes in the ROH region. Results: (1) A total of 39 cases of ROH were detected, with a positive rate of 0.76% (39/5 116). Among them, 25 cases (64%, 25/39) were detected only on single chromosome, and chromosome 11 had the highest detection rate, suggesting the risk of uniparental disomy; fourteen cases (36%,14/39) were detected on multiple chromosomes, most commonly on chromosomes 11, 1, 3, 4 and 8. (2) The number of cases and detection rate of ROH detected by different prenatal diagnosis indicators were as follows: 12 cases (1.78%, 12/676) in pregnant women with abnormal non-invasive prenatal testing result, 12 cases (0.37%, 12/3 284) in pregnant women with ultrasound abnormality, 4 cases (4/4) in pregnant women with consanguineous marriage, 3 cases (0.92%, 3/326) in pregnant women with previous adverse pregnancy, 2 cases (1.15%, 2/174) in pregnant women with high risk of serology in screening, 2 cases (4.00%, 2/50) in pregnant women with abnormal fetal chromosomal karyotype, 2 cases (0.79%, 2/253) in pregnant women with advanced maternal age, 1 case (0.56%, 1/178) in pregnant women with related parental genetic factors and 1 case (0.58%, 1/171) in pregnant women with the other factors. (3) The follow-up results of 39 cases of prenatal ROH showed that there were 16 cases of term birth, 15 cases of termination of pregnancy, 2 cases of preterm births, 1 case of fetal death and 5 cases lost to follow-up. Conclusions: Chromosomal ROH phenomenon is not rare. By analyzing the detection rate of ROH in prenatal diagnosis, combined with the results of fetal phenotype and postpartum follow-up, the clinical characteristics of ROH are discussed, so as to better understand the relationship between ROH and its phenotype.

Abstract
Objective: To investigate the pathological characteristics of singleton placenta with abnormal shape and its influence on the outcome of maternal-fetal pregnancy. Methods: The clinicopathological data of singleton placentas with abnormal shape from January 2014 to December 2020 in the Department of Pathology, Haidian Maternal and Children Health Hospital were analyzed retrospectively. Results: There were 130 singleton placentas with abnormal shape in this cohort, including 48 succenturiate placentas, 12 bilobed placentas, 50 marginate placentas, 13 circumvallate placentas, 3 annular placentas, 2 membranous placentas and 2 fenestrated placentas. Gestational age ranged from 29+5 to 40+4 weeks. There were 51 cases of premature rupture of membranes, 11 cases of placenta previa, 5 cases of placental abruption, 15 cases of placental adhesion/implantation and 27 cases of postpartum hemorrhage. There were 46 preterm fetuses,28 fetuses with fetal growth restriction, 22 fetuses with intrauterine distress, and 1 fetus with intrauterine death. Grossly, the placental lobules of succenturiate placentas had apparent size difference, while two lobules of bilobate placenta were more consistent. The chorionic plate size was smaller than the bottom plate of circumvallate placenta, the folded fetal membrane in the rim of placenta was thickened (termed marginate placenta if there was no thickening). The membranous placenta was characterized by a thin, large membrane-like shape. Annular placenta showed characteristic hollow cylinder, ring or horseshoe-shape. Fenestrated placenta was characterized by tissue defects near central area. Microscopically, functional/morphologic changes were the main manifestations of inadequate maternal-fetal perfusion, including villous infarction, distal villous dysplasia and excessive villous maturation. Conclusions: The abnormal shaped singleton placentas showed variable extent of inadequate maternal-fetal perfusion, which may lead to adverse pregnancy outcomes such as premature delivery, fetal growth restriction, intrauterine distress or fetal death.

Abstract
BACKGROUND The disease pathology for diabetes mellitus patients with chronic kidney disease (CKD) may be diabetic nephropathy (DN), non-diabetic renal disease (NDRD), or DN combined with NDRD. Considering that the prognosis and treatment of DN and NDRD differ, their differential diagnosis is of significance. Renal pathological biopsy is the gold standard for diagnosing DN and NDRD. However, it is invasive and cannot be implemented in many patients due to contraindications. This article constructed a new noninvasive evaluation model for differentiating DN and NDRD. METHODS We retrospectively screened 1,030 patients with type 2 diabetes who has undergone kidney biopsy from January 2005 to March 2017 in a single center. Variables were ranked according to importance, and the machine learning methods (random forest, RF, and support vector machine, SVM) were then used to construct the model. The final model was validated with an external group (338 patients, April 2017-April 2019). RESULTS In total, 929 patients were assigned. Ten variables were selected for model development. The areas under the receiver operating characteristic curves (AUCROCs) for the RF and SVM methods were 0.953 and 0.947, respectively. Additionally, 329 patients were analyzed for external validation. The AUCROCs for the external validation of the RF and SVM methods were 0.920 and 0.911, respectively. CONCLUSION We successfully constructed a predictive model for DN and NDRD using machine learning methods, which were better than our regression methods.

Abstract
Objective: To analyze the current adherence to imatinib in patients with gastrointestinal stromal tumors (GIST) in China and its influencing factors. Methods: A cross-sectional survey was conducted. Study period: from October 1, 2020 to November 31, 2020. Study subjects: GIST patients taking imatinib who were diagnosed and treated in public tertiary level A general hospitals or oncology hospitals; those who had not been pathologically diagnosed, those who never received imatinib, or those who had taken imatinib in the past but stopped afterwards were excluded. The Questionnaire Star online surgery platform was used to design a questionnaire about the adherence to adjuvant imatinib therapy of Chinese GIST patients. The link of questionnaire was sent through WeChat. The questionnaire contained basic information of patients, medication status and Morisky Medication Adherence Scale. Results: A total of 2162 questionnaires from 31 provinces, autonomous regions, and municipalities were collected, of which 2005 were valid questionnaires, with an effective rate of 92.7%. The survey subjects included 1104 males and 901 females, with a median age of 56 (22-91) years old. Working status: 609 cases (30.4%) in the work unit, 729 cases (36.4%) of retirement, 667 cases of flexible employment or unemployment (33.3%). Education level: 477 cases (23.8%) with bachelor degree or above, 658 cases (32.8%) of high school, 782 cases (39.0%) of elementary or junior high school, 88 cases (4.4%) without education. Marital status: 1789 cases (89.2%) were married, 179 cases (8.9%) divorced or widowed, 37 cases (1.8%) unmarried. Two hundred and ninety-four patients (14.7%) had metastasis when they were first diagnosed, including 203 liver metastases, 52 peritoneal metastases, and 39 other metastases. One thousand eight hundred and sixty-nine patients underwent surgical treatment, of whom 1642 (81.9%) achieved complete resection. The median time of taking imatinib was 25 (1-200) months. Common adverse reactions of imatinib included 1701 cases (84.8%) of periorbital edema, 1031 cases (51.4%) of leukopenia, 948 cases (47.3%) of fatigue, 781 cases (39.0%) of nausea and vomiting, 709 cases (35.4%) of rash, and 670 cases (33.4%) of lower extremity edema. The score of the Morisky Medication Adherence Scale showed that 392 cases (19.6%) had poor adherence, 1023 cases (51.0%) had moderate adherence, and 590 cases (29.4%) had good adherence. Univariate analysis showed that gender, age, work status, economic income, residence, education level, marriage, the duration of taking medication and adverse reactions were associated with adherence to adjuvant imatinib therapy (all P<0.05). Multivariate analysis showed that female (OR=1.264, P=0.009), non-retirement (OR=1.454, P=0.001), monthly income ≤4000 yuan (OR=1.280, P=0.036), township residents (OR=1.332, P=0.005), unmarried or divorced or widowed (OR=1.362, P=0.026), the duration of imatinib medication >36 months (OR=1.478, P<0.001) and adverse reactions (OR=1.719, P=0.048) were independent risk factors for poor adherence to adjuvant imatinib. Among patients undergoing complete resection, 324 (19.7%) had poor adherence, 836 (50.9%) had moderate adherence, and 482 (29.4%) had good adherence. Meanwhile, 55 patients with good adherence (11.4%) developed recurrence after surgery, 121 patients with moderate adherence (14.5%) developed recurrence, 61 patients with poor adherence (18.8%) developed recurrence, and the difference was statistically significant (P=0.017). Conclusions: The adherence to adjuvant therapy with imatinib in Chinese GIST patients is relatively poor. Females, non-retirement, monthly income ≤4000 yuan, township residents, unmarried or divorced or widowed, the duration of imatinib medication >36 months, and adverse reactions are independently associated with poor adherence of GIST patients. Those with poor adherence have a higher risk of recurrence after surgery. Positive interventions based on the above risk factors are advocated to improve the prognosis of patients with GIST.

Abstract
A recent focus of quantum spin liquid (QSL) studies is how disorder/randomness in a QSL candidate affects its true magnetic ground state. The ultimate question is whether the QSL survives disorder or the disorder leads to a “spin-liquid-like” state, such as the proposed random-singlet (RS) state. Since disorder is a standard feature of most QSL candidates, this question represents a major challenge for QSL candidates. YbMgGaO4, a triangular lattice antiferromagnet with effective spin-1/2 Yb3+ions, is an ideal system to address this question, since it shows no long-range magnetic ordering with Mg/Ga site disorder. Despite the intensive study, it remains unresolved as to whether YbMgGaO4 is a QSL or in the RS state. Here, through ultralow-temperature thermal conductivity and magnetic torque measurements, plus specific heat and DC magnetization data, we observed a residual κ0/T term and series of quantum spin state transitions in the zero temperature limit for YbMgGaO4. These observations strongly suggest that a QSL state with itinerant excitations and quantum spin fluctuations survives disorder in YbMgGaO4. It remains an open question as to whether the quantum spin liquid state survives material disorder, or is replaced by some spin-liquid like state. Here, Rao et al succeed in resolving a resolving a κ0/T residual in the thermal conductivity of YbMgGaO4 strongly suggesting the survival of the quantum spin liquid state.

Abstract
We theoretically design and experimentally generate the flexibly modulated Poincaré sphere vector optical field (PS-VOF), which can be constructed by flattening the Poincaré sphere surface. This new kind of PS-VOF provides additional degrees of freedom to modulate the spatial structure of polarization based on Poincaré sphere. The focal property of the PS-VOF is further studied, and we focus on studying the polarization coverage of the Poincaré sphere in the focal plane. In focusing process, the conversion and annihilation of spin angular momentum are presented. In addition, when the proportion of right-handed polarizations from the northern hemisphere of the Poincaré sphere satisfies Golden ratio (0.618) in the input plane, a full PS-VOF with high quality can be achieved in the focal plane. We hope this study of PS-VOF in both input and focal planes can enrich the family of VOFs, provide a new avenue in studying VOFs based on the Poincaré sphere, and can be potentially applied in the regions with sensitivity to polarizations.

Abstract
BACKGROUND Erythropoiesis-stimulating agents (ESAs) constitute an important treatment option for anemia in hemodialysis (HD) patients. We investigated the relationships among the dosage of ESA, erythropoietin resistance index (ERI) scores, and mortality in Chinese MHD patients. METHODS This multicenter observational retrospective study included MHD patients from 16 blood purification centers (n = 824) who underwent HD in 2011-2015 and were followed up until December 31, 2016. We collected demographic variables, HD parameters, laboratory values, and ESA dosages. Patients were grouped into quartiles according to ESA dosage to study the effect of ESA dosage on all-cause mortality. The ERI was calculated as follows: ESA (IU/week)/weight (kg)/hemoglobin levels (g/dL). We also compared outcomes among the patients stratified into quartiles according to ERI scores. We used the Cox proportional hazards model to measure the relationships between the ESA dosage, ERI scores, and all-cause mortality. Using propensity score matching, we compared mortality between groups according to ERI scores, classified as either > or ≤12.80. RESULTS In total, 824 patients were enrolled in the study; 200 (24.3%) all-cause deaths occurred within the observation period. Kaplan-Meier analyses showed that patients administered high dosages of ESAs had significantly worse survival than those administered low dosages of ESAs. A multivariate Cox regression identified that high dosages of ESAs could significantly predict mortality (ESA dosage >10,000.0 IU/week, HR = 1.59, 95% confidence intervals (CIs) (1.04, 2.42), and p = 0.031). Our analysis also indicated a significant increase in the risk of mortality in patients with high ERI scores. Propensity score matching-analyses confirmed that ERI > 12.80 could significantly predict mortality (HR = 1.56, 95% CI [1.11, 2.18], and p = 0.010). CONCLUSIONS Our data suggested that ESA dosages >10,000.0 IU/week in the first 3 months constitute an independent predictor of all-cause mortality among Chinese MHD patients. A higher degree of resistance to ESA was related to a higher risk of all-cause mortality.

Abstract
Objective: To explore the method of predicting high lymph node load in patients with early breast cancer to avoid unnecessary sentinel lymph node biopsy. Methods: The clinicopathological and thoracic multi-slice spiral CT (MSCT) data of 2620 patients with early (cT1~2N0M0) breast cancer treated in the Affiliated Cancer Hospital of Zhengzhou University from January 1, 2014 to August 1, 2018 were collected. According to the postoperative pathological results, the patients were divided into the group with axillaryhigh lymph node burden (HNB) and the non-HNB group. The influencing factors of axillary lymph node burden in patients with early breast cancer were determined by univariate and multivariate analysis, and the diagnostic model of MSCT to HNB was established. The best cutoff value for the diagnosis of HNB was determined through analyzing the receiver operative characteristic (ROC) curve, and the consistency between MSCT diagnosis and pathological diagnosis was evaluated by Kappa test. Results: Among the 2 620 patients, 168 were diagnosed of HNB. Univariate analysis showed that the tumor size, the status of human epidermal growth factor receptor 2 (HER-2), the number of abnormal lymph nodes showed in MSCT, the ratio of the length to the diameter of the maximum abnormal lymph node as shown in MSCT, the condition of the maximum abnormal lymph node door, and the parenchyma of the maximum abnormal lymph node were related to axillary lymph node burden in patients with early breast cancer (P<0.05). Multivariate analysis showed that the number of abnormal lymph nodes showed in MSCT was an independent influencing factor of axillary HNB in patients with early breast cancer. Compared with patients without abnormal lymph nodes, the OR values of patients with 1, 2, 3 or more abnormal lymph nodes displayed by MSCT and in axillary HNB status were 3.305, 9.379, 126.163 and 780.953, respectively. Using 3 or more abnormal lymph nodes detected by MSCT to predict the area under the ROC curve of axillary HNB in patients with early breast cancer, the area was 0.928, the sensitivity was 82.1%, the specificity was 95.4%, and the accuracy was 94.5%. Kappa test showed that the consistency between MSCT diagnosis and pathological diagnosis was relatively high (Kappa=0.629, P<0.001). Conclusions: The number of abnormal lymph nodes showed in MSCT is an independent influencing factor of axillary HNB in patients with early breast cancer. Taking 3 or more abnormal lymph nodes showed in MSCT as the threshold can help to predict the axillary HNB status of early breast cancer patients and exempt some of them from unnecessary sentinel lymph node biopsy.

Abstract
It is well known that the dairy cow production is very sensitive to environmental factors, including high temperature, high humidity and radiant heat sources. High temperature-induced heat stress is the main environmental factor that causes oxidative stress and apoptosis, which affects the development of mammary glands in dairy cows. Dihydromyricetin (DMY) is a nature flavonoid compound extracted from Ampelopsis grossedentata; it has been shown to have various pharmacological functions, such as anti-inflammation, antitumor and liver protection. The present study aims to evaluate the protective effect of DMY on heat stress-induced dairy cow mammary epithelial cells (DCMECs) apoptosis and explore the potential mechanisms. The results show that heat stress triggers heat shock response and reduces cell viability in DCMECs; pretreatment of DCMECs with DMY (25 μM) for 12 h significantly alleviates the negative effects of heat stress on cells. DMY can provide cytoprotective effects by suppressing heat stress-caused mitochondrial membrane depolarization and mitochondrial dysfunction, Bax and Caspase 3 activity, and modulation of oxidative enzymes, thereby preventing ROS production and apoptosis in DCMECs. Importantly, DMY treatment could attenuate heat stress-induced mitochondrial fragmentation through mediating the expression of mitochondrial fission and fusion-related genes, including Dynamin related protein 1 (Drp1), Mitochondrial fission 1 protein (Fis1), and Mitofusin1, 2 (Mfn1, 2). Above all, our findings demonstrate that DMY could protect DCMECs against heat stress-induced injury through preventing oxidative stress, the imbalance of mitochondrial fission and fusion, which provides useful evidence that DMY can be a promising therapeutic drug for protecting heat stress-induced mammary glands injury and mastitis.

Abstract
Objective: To provide the risk stratification method of hepatoblastoma (HB) suitable for implementation in China and explore the new treatment method for high-risk HB patients. Methods: A total of 100 cases of children and adolescents under 18 years old with newly diagnosed HB in Sun Yat-sen University Cancer Center and Sun Yat-sen University First Affiliated Hospital from September 2014 to September 2018 were included. According to the clinical stage, AFP level, pathological subtype and other factors, patients were stratified into four groups: extremely low-, low-, intermediate- and high-risk. The patients at very low risk were treated with surgery only and followed-up. The patients at very low risk were treated with C5V(Cisplatin+ 5-Fluroracil+ Vincristine) regimen for 4 courses. The patients at intermediate risk were treated with C5VD(Cisplatin+ 5-Fluroracil+ Vincristine+ Doxorubicin)regimen before and after surgery for 6-8 courses. The patients at high risk were treated with C5VD and IIV (ifoshamide+ irinotecan+ vincristine) alternately before and after surgery for 8 courses. Results: One hundred patients were stratified into extremely low-risk, low-risk, medium-risk and high-risk groups for 2, 10, 51 and 37 cases, respectively. Eighty three cases had evaluable lesions before chemotherapy. Among them, 65 patients achieved partial remission, stable disease and progressive disease were observed in 10, and 8 cases, respectively, with a response rate of 78.3%. During a median follow-up of 20 months, 30 patients experienced tumor relapse or progression, and 27 of them died. The 2-years progression-free survival (PFS) and overall survival (OS) rates were 69.2% and 72.0%, respectively. The 2-years PFS rates of patients with extremely low risk, low risk, medium risk and high risk were 100%, 88.9%, 75.3% and 43.2%, respectively. The 2-years OS rates were 100%, 100%, 81.0% and 44.8%, respectively. Conclusions: The novel HB risk classification is simple and feasible. With active comprehensive treatment, patients at extremely low-, low- and medium-risk have excellent outcomes. The survival rate of high-risk HB patients remains to be improved, and new treatment strategies need to be explored.

Abstract
The optical properties of microlens arrays may be significantly affected by the optical crosstalk effect between adjacent lenses. Recently, this issue has triggered increasing attention in the scientific community. In this study, an integrated microlens array (MLA) consisting of self-aligning convergent waveguides of microlenses was fabricated. The optical crosstalk effect does not influence the performance of such system. Based on the self-focusing effect principle, self-writing of the waveguide array was achieved in a photosensitive polymer. The light collection and guiding performance of the MLA with and without thermal cross-linking treatment was analyzed in depth. The relation between the stray light and the filling rate of the MLA shows that a high filling rate decreases the optical crosstalk. Finally, an integrated MLA with a large area, high uniformity, and excellent optical performance was fabricated.

Abstract
Objective: To analyze the clinical characteristics of infantile Takayasu arteritis and the efficacy of infliximab (IFX). Methods: Clinical manifestations, laboratory investigations and infliximab intervention of a case with infantile Takayasu arteritis, who was admitted to Department of Rheumatism and Immunology, Children's Hospital, Capital Institute of Pediatrics in January 2018, were reviewed and analyzed. The related literature published from the beginning to March 2020 were retrieved from CNKI, Wanfang, SinoMed and PubMed with the keywords of"Takayasu arteritis","Infant" in both Chinese and English. Results: This case was a 70-day-old boy admitted due to recurrent fever for 20 days. On admission, his blood pressure were 104/90, 95/59, 125/80, and 152/125 mmHg (1 mmHg=0.133 kPa) in the right arm, left arm, right leg, and left leg, respectively. The complete blood cell count showed leukocytosis (22.6×109/L), thrombocytosis (858×109/L) and mild anemia (80 g/L). He also had elevated erythrocyte sedimentation rate (119 mm/1h), serum ferritin (598 μg/L) and C-reactive protein (112 mg/L). Computed tomographic angiography (CTA) showed narrowing of the thoracic and abdominal aorta, with thickening and heterogenous enhancement of the vessel wall. Coronary artery ultrasound detected dilatation and wall thickening of the bilateral coronary arteries, and uneven dilatation of the middle segment of the right coronary artery, showing bead-like change. Vessel wall thickening was also found in the other main arteries, including both femoral arteries, axillary arteries, carotid arteries, and subclavian arteries, and both superficial femoral arteries were slightly narrowed in the distal segments. The diagnosis of TA was confirmed, and the boy was treated with infliximab monotherapy (5 mg/(kg·every time), a total of 13 times). Then his body temperature and all inflammatory markers were normalized, and the vascular pathology was resolved according to the radiography. No side effects such as allergy or infection were noted during the treatment. During the 2 years and 6 months of follow-up, the boy maintained normal growth and development. Literature review found 8 related articles, and one of them was in Chinese but had limited information. In the other 7 papers, a total of 7 infants with TA were reported. The most common symptom was fever (5 cases), and inflammatory markers usually elevated, and the most common affected artery was abdominal aorta (6 cases). Most cases were treated with glucocorticoid. Conclusions: TA is a rare disease in infants, usually presents with fever and increased inflammatory markers. At the early stage, infliximab monotherapy could effectively control the symptoms and ensure normal growth and development.

Abstract
Protein phosphatase 4 (PPP4) is a protein phosphatase that, although highly expressed in the testis, currently has an unclear physiological role in this tissue. Here, we show that deletion of PPP4 catalytic subunit gene Ppp4c in the mouse causes male-specific infertility. Loss of PPP4C, when assessed by light microscopy, did not obviously affect many aspects of the morphology of spermatogenesis, including acrosome formation, nuclear condensation and elongation, mitochondrial sheaths arrangement and '9 + 2' flagellar structure assembly. However, the PPP4C mutant had sperm tail bending defects (head-bent-back), low sperm count, poor sperm motility and had cytoplasmic remnants attached to the middle piece of the tail. The cytoplasmic remnants were further investigated by transmission electron microscopy to reveal that a defect in cytoplasm removal appeared to play a significant role in the observed spermiogenesis failure and resulting male infertility. A lack of PPP4 during spermatogenesis causes defects that are reminiscent of oligoasthenoteratospermia (OAT), which is a common cause of male infertility in humans. Like the lack of functional PPP4 in the mouse model, OAT is characterized by abnormal sperm morphology, low sperm count and poor sperm motility. Although the causes of OAT are probably heterogeneous, including mutation of various genes and environmentally induced defects, the detailed molecular mechanism(s) has remained unclear. Our discovery that the PPP4C-deficient mouse model shares features with human OAT might offer a useful model for further studies of this currently poorly understood disorder.

Abstract
Objective: To investigate the clinical characteristics and related factors of acute tubular necrosis (ATN) in patients with minimal change disease (MCD). Methods: Patients from Chinese PLA General Hospital who were pathologically diagnosed with MCD and had clinical manifestations of nephrotic syndrome from January 1, 2013 to December 31, 2019 were included. The clinical and pathological data of patients were retrospectively analyzed. Meanwhile, the incidence and clinical characteristics of ATN in different age groups were compared. The risk factors for ATN were assessed using binary logistic regression. Results: A total of 525 patients were included, with a gender ratio of 1.56∶1 (male: female), aged 33 (21, 48) years old. ATN occurred in 49 (9.3%) of 525 patients, of which 34 were male and 15 were female. The incidence of ATN increased with age in MCD patients of different age groups (χ(2)=31.442, P<0.001). The incidence of ATN in groups of age≤20 years, 21-40 years, 41-60 years, and >60 years was 2.4% (3/123), 5.2% (10/192), 13.2% (20/152) and 27.6% (16/58), respectively. Elevations of alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transpeptidase (GGT) and serum IgE occurred in 92 patients (17.5%), 53 patients (10.1%), 99 patients (18.9%), and 303 patients (57.7%), respectively. There were significant differences in age, ALT, serum creatinine, serum urea nitrogen, history of diabetes and history of hypertension between non-ATN group and ATN group (all P<0.05). The results of logistic regression analysis showed that>40 years old (OR=6.283, 95% CI: 2.695-14.649, P<0.001) and serum albumin (OR=0.924, 95% CI: 0.857-0.997, P=0.040) was independently associated with ATN in MCD patients. Conclusion: Age>40 years is an independent risk factor and serum albumin is a protective factor for ATN in MCD patients.

Abstract
LINC00355 has been reported aberrantly over-expressed and associated with poor prognosis in various types of cancer. However, reports regarding the effect of LINC00355 on lung squamous cell carcinoma (SCC) are rare. This study aimed to explore the function of LINC00355 in the development and progression of lung SCC and reveal the underlying mechanism. The expression and subcellular location of LINC00355 were determined by qRT-PCR and RNA-FISH, respectively. The lung SCC cell growth was analyzed by CCK-8 assay, transwell invasion, wound healing, colony formation, and flow cytometry assays. Reactive oxygen species level was evaluated by DCFH-DA probes. Bioinformatics online websites, luciferase reporter assay, RNA binding protein immunoprecipitation (RIP), and RNA pull-down assays were utilized to investigate the interaction among LINC00355, miR-466, and Ly-1 antibody reactive clone (LYAR). The results showed that LINC00355 was upregulated in lung SCC and was positively associated with poor overall survival in lung SCC patients. LINC00355 was mainly located in the cytoplasm of SCC cells. Additionally, LINC0035 functioned as a competing endogenous RNA (ceRNA) to target miR-466, and LYAR was identified as a direct target of miR-466. LINC00355 expression negatively correlated with miR-466 level, and positively correlated with LYAR level. Mechanistically, knockdown of LINC00355 inhibited cell proliferation, migration and invasion, promoted cell apoptosis in vitro, and suppressed tumor growth in vivo through targeting miR-466, and thus down-regulated LYAR expression. These findings provide a new sight for understanding the molecular mechanism of lung SCC and indicate that LINC00355 may serve as a potential biomarker for the diagnosis and treatment of lung SCC.

Abstract
Objective: Platelet-derived growth factor α (PDGFRA)-mutant gastrointestinal stromal tumor (GIST) is a relatively rare disease, whose clinicopathological characteristics and prognosis have been poorly studied. In this paper, the clinicopathological features and prognostic factors of PDGFRA-mutant GIST are investigated to provide more data for its understanding and treatment. Methods: A retrospective case-control study was used to collect the medical records of patients with GIST who underwent surgical resection in Zhongshan Hospital of Fudan University from January 2015 to August 2019. Patients with PDGFRA-mutant GIST were enrolled, and those with synonymous PDGFRA mutations, non-tumor-related deaths, and lack of clinicopathological data were excluded. The clinicopathological data were collected and the risk factors associated with prognosis were analyzed. Results: Among the enrolled 59 patients, there were 41 males (69.5%) and 18 females (30.5%) with the median age of 60 (25-79) years. All tumors originated from the stomach. The tumor size was 5 (3-7) cm, and the mitotic count was 2 (1-4)/50 high-power fields (HPF). According to the modified NIH risk stratification, 8 cases were classified as very low risk (13.6%), 25 cases as low risk (42.4%), 14 cases as moderate risk (23.7%), and 12 cases as high risk (20.3%). There were 7 cases of exon 12 mutation and 52 cases of exon 18 mutation (including 36 cases of D842V mutation). A comparison of clinicopathological features between the D842V mutation group and the non-D842V mutation group showed no statistically significant difference (all P>0.05). During a median follow-up of 21 (0-59) months, the 1- and 3-year relapse-free survival (RFS) rates of all the patients were 96.6% and 91.5%, respectively. There were 8 cases of recurrence and 3 cases of death. Six GIST patients with D842V mutation had tumor recurrence after operation, of whom 4 cases achieved varying degrees of tumor remission after being treated with dasatinib or avapritinib. Log-rank analysis showed that the overall survival (OS) of male was better than that of female (100% vs. 83.3%, P=0.046), but there was no significant difference in OS among patients with different risk grades (P=0.057). The RFS and OS of patients with D842V mutation and non-D842V mutation, exon 12 and exon 18 mutation were similar (all P>0.05). Univariate Cox analysis showed that RFS was associated with gender (P=0.010), tumor size (P=0.042), mitotic count (P=0.003), and the modified NIH risk stratification (P=0.042), while multivariate analysis revealed that higher risk grade was an independent risk factor for recurrence of PDGFRA-mutant GIST (HR=12.796, 95%CI: 1.326-123.501, P=0.028). Gender was an independent factor for recurrence, and the risk of recurrence in males was lower than that in females (HR=0.154, 95%CI: 0.028-0.841, P=0.031). Conclusions: Gender and the modified NIH risk stratification are independent risk factors for recurrence of PDGFRA-mutant GIST, while patients with D842V and non-D842V mutation, and exon 12 and exon 18 mutation have a similar risk of recurrence and death.

Abstract
Objective: To summarize the efficiency and long-term outcomes of limited-stage Hodgkin lymphoma in children and adolescents with ABVD therapy and determined whether omitting radiotherapy for a low-risk patient enabled the achievement of complete response (CR) after chemotherapy. Methods: We retrospectively analyzed data from 13 y (2004-2016) from patients aged ≤18 y with limited-stage HL admitted to the Sun Yat-sen University Cancer Center. Patients received treatment with ABVD chemotherapy alone or ABVD chemotherapy followed by low-dose involved field radiotherapy. Results: Total 85 subjects were eligible for study inclusion; the median age was 12 (3-18) y; 66 (77.6%) were men, 80 (94.1%) had stage-II disease, 56 (65.9%) were at low-risk, and the median follow-up duration was 72 (8-196) months; 12 relapsed, 2 had secondary neoplasm, and 2 died. The 5-year event free survival (EFS) was (85.6±3.8) %, and the overall survival (OS) was 100%. The 5-year EFS and OS was (89.1±4.2) % and 100%, respectively, for the low-risk cohort and (79.3±7.5) % and 100%, respectively for the intermediate-risk cohort. Among the 39 low-risk patients who achieved CR after chemotherapy, 15 received treatment with chemotherapy followed by LD-IFRT. In the exploratory subset analysis, the low-risk cohort who achieved CR after chemotherapy, the 5-year EFS for comparing ABVD alone with chemotherapy followed by LD-IFRT was (87.0±7.0) % versus 100% (P=0.506) , and the OS was 100% for both the groups. Conclusions: Our retrospective analysis showed excellent survival of limited-stage HL patients with ABVD therapy. For patients who achieving CR after chemotherapy with low-risk HL, received chemotherapy followed by LD-IFRT does not improve 5-year OS and EFS. The use of risk- and response-based stratification may facilitate the development of effective and less toxic protocols.

Abstract
The most fascinating feature of certain two-dimensional (2D) gapless quantum spin liquid (QSL) is that their spinon excitations behave like the fermionic carriers of a paramagnetic metal. The spinon Fermi surface is then expected to produce a linear increase of the thermal conductivity with temperature that should manifest via a residual value (κ0/T) in the zero-temperature limit. However, this linear in T behavior has been reported for very few QSL candidates. Here, we studied the ultralow-temperature thermal conductivity of an effective spin-1/2 triangular QSL candidate Na2BaCo(PO4)2, which has an antiferromagnetic order at very low temperature (TN ~ 148 mK), and observed a finite κ0/T extrapolated from the data above TN. Moreover, while approaching zero temperature, it exhibits series of quantum spin state transitions with applied field along the c axis. These observations indicate that Na2BaCo(PO4)2 possibly behaves as a gapless QSL with itinerant spin excitations above TN and its strong quantum spin fluctuations persist below TN.

Abstract
Objective: To investigate the clinical features and prognosis of interstitial lung disease patients with positive anti-neutrophil cytoplasmic antibody. Methods: The patients with interstitial lung disease who visited Peking Union Medical College Hospital from March 2006 to March 2016 were divided into three groups: interstitial lung disease with ANCA-positive(ANCA-ILD), connective tissue disease associated interstitial lung disease and interstitial pneumonia with autoimmune features (CTD-ILD/IPAF) and idiopathic interstitial pneumonia (IIP). The three groups were analyzed in terms of clinical manifestations, serology, lung function, imaging, survival and recurrence. Results: Two hundred and seventy four patients were enrolled and 38 (14%) were ANCA-positive of whom 16 were male and 22 were female. The age of 38 ANCA-positive patients was (59±10) years and the follow-up time was (52±31) months. Seven among the 38 ANCA-positive patients died and the death rate is 18.42%. The ANCA-positive patients with interstitial lung disease have higher onset age (ANCA-ILD:59±10,CTD-ILD/IPAF:52±10,IIP:53±11,H=19.29, P<0.001), lower hemoglobin (ANCA-ILD: 129±21, CTD-ILD/IPAF: 138±15, IIP: 140±19, H=8.17, P=0.017), higher erythrocyte sedimentation rate (ANCA-ILD:45±35, CTD-ILD/IPAF:26±24,IIP:19±22,H=19.73, P<0.001), lower lung function improvement rate after treatment (ANCA-ILD:31%,CTD-ILD/IPAF:59%,IIP: 39%,χ(2)=11.74,P=0.003), lower absorption rate of CT lesion (ANCA-ILD:61%,CTD-ILD/IPAF:82%,IIP:67%, χ(2)=9.23,P=0.010) and higher death rate(ANCA-ILD:18%,CTD-ILD/IPAF:6%,IIP:12%, χ(2)=7.16,P=0.028). Conclusions: There are significant differences in clinical characteristics between ANCA-positive patients and other types of pulmonary interstitial disease. And both the treatment effect and the prognosis is poor for the ANCA-positive patients.

Abstract
OBJECTIVE The optimal treatment for gastrointestinal stromal tumor (GIST) of the rectum is controversial due to the extremely low incidence of the disease. The aim of the present study was to compare the clinical outcomes of different treatment modalities for rectal GIST by reviewing the 14-year experience in our center. METHOD Medical records of rectal GIST patients who received surgical treatment in our center between January 2004 to December 2017 were reviewed retrospectively. Overall survival (OS) and recurrence-free survival (RFS) were used as the observation endpoints. RESULTS Included in this study were 71 GIST patients, including 42 patients who underwent local excision (LE) and 29 patients who underwent segmental resection (SR). There were differences in tumor size (P = 0.001) and malignant risk grade (P = 0.007). The LE approach achieved a lower rate of R0 resection than SR (29/42 vs.27/29, P = 0.015) and shorter hospital stay (P = 0.004). Preoperative imatinib mesylate (IM) therapy improved the rate of sphincter-sparing surgery for patients with tumors in the very low segment of the rectum (P = 0.012) and offered better R0 resection margins (P = 0.027). Multivariate analysis showed that the resection margin status (P = 0.014), risk stratification (P = 0.001) and IM therapy (P = 0.042) were independent factors affecting RFS of rectal GIST patients but not the surgical modalities (LE vs. SR, P = 0.802). Multivariate analysis showed no significant impact of these variables on OS. CONCLUSION Selection of surgical modalities has no significant impact on the prognosis. Local excision is the preferred surgical modality for resectable rectal GIST by virtue of less injury and shorter hospital stay. IM therapy has proved to be associated with improved RFS for rectal GIST patients.

Abstract
OBJECTIVE To analyze the results of echinococcosis surveillance in Yixing City from 2011 to 2018, so as to provide insights into echinococcosis control in the city. METHODS All echinococcosis cases reported in Yixing City since 2007 that were captured from the China National Notifiable Infectious Disease Reporting Information System of Chinese Center for Disease Control and Prevention received a case study, and serological test and transabdominal B-mode ultrasound screening were performed among permanent residents and mutton market workers in Fangdong and Fangzhuang villages of Yixing City from 2011 to 2018. The cyst, mass and tubercle were detected in the liver and lung of the sheep from the mutton markets, and the Echinococcus coproantigen was detected in the canine stool samples from Fangdong and Fangzhuang villages. In addition, the awareness of echinococcosis prevention and control knowledge was investigated in the two villages using a questionnaire survey from 2011 to 2018. RESULTS A total of 7 cases with echinococcosis had been reported in Yixing City since 2007, with prevalence of 0.56/100 000, and all cases were E. granulosus-infected patients, including 2 cases with a history to travel to echinococcosis-endemic areas and 5 cases with a history of working in local mutton markets or dog contacts. From 2011 to 2018, a total of 1 861 residents received serological tests, with 0.54% seropositivity, and no seropositives were detected since 2016. Among the 1 807 individuals receiving transabdominal B-mode ultrasound screening, suspected cysts were found in 143 individuals (7.91%), and 1.40% (2/143) seropositivity was detected in these individuals. The mean positive rate of the Echinococcus coproantigen was 0.67% (3 /446) in the canine stool samples. Among the 4 010 sheep liver and lung specimens sampled from the mutton markets, 7 specimens (0.17%) were detected with cysts or tubercles. In addition, the mean awareness rate of echinococcosis prevention and control knowledge was 76.95% among the 538 subjects receiving questionnaire surveys from 2011 to 2018, and the overall awareness appeared a tendency towards a rise year after year. CONCLUSIONS Although the prevalence of echinococcosis and the seropositivity of anti-Echinococcus antibodies are low, there is still a risk of transmission of echinococcosis in Yixing City. The surveillance of echinococcosis should continue to be intensified and related control interventions are required.

Abstract
OBJECTIVE Venous thromboembolism (VTE) is a fatal complication and the most common preventable cause of death in hospitals. The risk-to-benefit ratio of thromboprophylaxis depends on the performance of the risk assessment model. A linear model, the Padua model, is recommended for medical inpatients in the United States but is not suitable for Chinese inpatients due to differences in race and disease spectrum. Currently, machine learning (ML) methods show advantages in modeling complex data patterns and have been applied to clinical data analysis. This study aimed to build VTE risk assessment ML models among Chinese inpatients and compare the predictive validity of the ML models with that of the Padua model. METHODS We used 376 patients, including 188 patients with VTE, to build a model and then evaluate the predictive validity of the model in a consecutive clinical dataset from Peking Union Medical College Hospital. Nine widely used ML methods were trained on the model derivation set and then compared with the Padua model. RESULTS Among the nine ML methods, random forest (RF), boosting-based methods, and logistic regression achieved a higher specificity, Youden index, positive predictive value, and area under the receiver operating characteristic curve than the Padua model on both the test and clinical validation sets. However, their sensitivities were inferior to that of the Padua model. Combined with the receiver operating characteristic curve, RF, as the best performing model, maintained high specificity with relatively better sensitivity and captured VTE patients' patterns more precisely. CONCLUSIONS Advances in ML technology provide powerful tools for medical data analysis, and choosing models conforming to the disease pattern would achieve good performance. Popular ML models do not surpass the Padua model on all indicators of validity, and the drawback of low sensitivity should be improved upon in the future.

Abstract
AIM Serum anti-phospholipase A2 receptor (anti-PLA2R) antibodies are highly accurate in diagnosing idiopathic membranous nephropathy (IMN) in populations with kidney disease. However, the diagnostic value of anti-PLA2R antibodies for IMN in diabetic kidney disease (DKD) is unclear. The objective of this study is to determine the diagnostic efficacy and the optimal cut-off value of this marker in populations with DKD. METHODS This study included 227 patients with type 2 diabetes who were admitted to the Department of Nephrology of the Chinese People's Liberation Army General Hospital from May 2016 to January 2018 and underwent pathological diagnosis by renal biopsy. Anti-PLA2R antibodies were detected by enzyme-linked immunosorbent assay in this population. According to the pathological results, the participants were divided into an IMN group and non-membranous nephropathy (non-MN) group. The clinical characteristics were analyzed, the diagnostic ability of anti-PLA2R antibodies was evaluated, and the receiver operating characteristic (ROC) curve was constructed to obtain the optimal cut-off value. RESULTS There were 45 patients in the IMN group, accounting for 19.8% of the study sample. The patients in this group were older at the time of renal biopsy than the non-MN group and presented a shorter duration of diabetes, better glycemic control, lower blood pressure and uric acid, and better renal function; in addition, their clinical symptoms indicated nephrotic syndrome. The optimal cut-off value for anti-PLA2R antibodies for the diagnosis of IMN in DKD was 2.71 Ru/ml, sensitivity was 0.800, specificity was 0.951, positive predictive value was 0.800, negative predictive value was 0.951, accuracy was 0.921, and the Yoden index was 0.750. The area under the ROC curve was 0.87 (95% CI, 0.788-0.952) (p < 0.001). CONCLUSIONS Patients in the IMN group were older, had better renal function and general condition, and the clinical symptoms indicated nephrotic syndrome. Anti-PLA2R antibodies had a good diagnostic performance for IMN in the population with DKD, and the optimal cut-off value was 2.71.

Abstract
Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumors in the gastrointestinal tract. Though surgical resection is the only radical treatment, postoperative recurrence and metastasis often occur. The first-line therapy for the treatment of recurrent, metastatic and unresectable GIST is imatinib. More than 80% of patients can benefit from imatinib treatment, but half of patients will still have recurrence or metastasis within 2 years after treatment initiation, and secondary drug resistance is a major cause of disease progression. Therefore, adeep understanding of the mechanisms of secondary drug resistance will guide us to develop personalized therapeutic schedule in the future. This article describes the mechanism of IM secondary resistance from the aspects of gene alteration, abnormal activation of signal transduction pathway, autophagy, apoptosis and drug concentration. It is found that single drug therapy has certain limitations in patients with secondary resistance to IM. Using IM combined with downstream signaling molecule inhibitors, autophagy inhibitors, insulin-like growth factor 1 receptor (IGF-1R) inhibitors, heat shock protein 90 (HSP90) inhibitors, cytotoxic T lymphocyte - associated antigen - 4 (CTLA - 4) antibodies and mitochondrial inhibitors provide us new therapeutic ideas. However, these combination treatments are still in the research phase, and further trials are needed to confirm the safety and efficacy. With the gradual deepening of research on drug resistance mechanisms, it will provide more solutions to the current serious drug resistance problem.

Abstract
BACKGROUND/AIMS Several pathological classification systems were commonly used in clinical practice to predict the prognosis of IgA nephropathy (IgAN). However, how prognostic value differs between these systems is unclear. The aim of this study was to compare the Lee grade, the Oxford classification, and the Haas classification and to find a simplified classification. METHODS We retrospectively analyzed IgAN cases diagnosed between January 2002 and December 2007. The endpoints were progression to end-stage renal disease (ESRD) or a ≥50% decline in estimated glomerular filtration rate (eGFR). The predictive capabilities were evaluated by comparing the ability of discrimination (continuous net reclassification) and calibration (Akaike information criterion [AIC]). RESULTS A total of 412 IgAN patients were included in the study. The average follow-up period was 80.62 ± 23.63 months. A total of 44 (10.68%) patients progressed to ESRD, and 70 (16.99%) patients showed a ≥50% decline in eGFR. All multivariate Cox regression models had limited power for high AIC values. The prognostic values of the Lee grade and the Oxford classification were higher than those of models containing only established baseline clinical indicators for progression to ESRD or a ≥50% decline in eGFR (Lee grade 0.50, 95% CI 0.21-0.74; Oxford classification 0.48, 95% CI 0.28-0.71). The prognostic value of the Haas classification was lower than that of the other pathological classification systems for progression to ESRD or a ≥50% decline in eGFR (Lee grade 0.53, 95% CI 0.23-0.92; Oxford classification 0.59, 95% CI 0.10-0.74). The prognostic value of hierarchical classification (Beijing classification) using M and T lesion was similar to the Oxford classification. CONCLUSIONS Both the Lee grade and the Oxford classification showed incremental prognostic values beyond established baseline clinical indicators. The Haas classification was slightly inferior to the Lee grade and the Oxford classification. The hierarchical classification (Beijing classification) using less pathological parameters does not lose predictive efficiency.

Abstract
Peroxisome proliferator activated receptor delta (PPARD) is a nuclear receptor transcription factor whose single nucleotide polymorphism (SNP), especially PPARD-87 T>C (rs2016520), may play an important role in expression regulation of PPARD. But its expression patterns as well as contribution in colorectal cancer (CRC) are still controversial. In this study, whether the intratumoral heterogeneity of polymorphism of PPARD-87 T>C (rs2016520) existed and its influence in CRC were investigated. Tumor masses from primary CRC patients were collected during the operation of tumorectomy, specimens at the different sites of the same tumor mass were sampled and stored individually. The SNP of PPARD-87 T>C was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), and the expression of PPARD in vivo was observed by immunohistochemistry. The correlation of PPARD -87 T>C intratumoral polymorphism and the clinicopathological parameters of patients was analyzed statistically. Tumor samples were collected from 106 CRC patients (70 males and 36 females) with an average age of 61.04±13.67 years. A total number of 808 samples (7.60±1.60 per patient) were mainly harvested at peripheral superficial (n=376), central superficial (n=163), invasive front (n=112) and mesenteric cancer foci (n=42) of tumor tissues as well as cancerous adjacent mucosa (n=104). PCR-RFLP analysis showed that T/T (n=460, 56.9%) and T/C (n=334, 41.3%) were the main genotypes of -87 T>C among these samples. Furthermore, intratumoral genotype of -87 T>C was homogeneous in 90 patients and heterogeneous in other 16 patients. The intratumoral heterogeneity was related to patients' age (P=0.016), tumor location (P=0.011) and the grade of differentiation (P=0.022). For patients with intratumoral heterogeneity, immunochemistry showed the expressions of PPARD were not influenced by T/T or T/C genotypes. Intratumoral heterogeneity of PPARD-87 T>C wildly existed in CRC, and associated with patients' age, tumor location and differentiation. However, the immunochemistry assay revealed that there's no significant link between heterogeneity and expression of PPARD.

Abstract
Chronic rhinosinusitis with nasal polyps (CRSwNP) is one of the common diseases. Involving the nasal passages and nasal passages, it may affect 10% of the global population. Surgical intervention is usually required. Its pathogenesis is a multielement and multistep complex process. Current multi-factor hypothesisplays a dominant role in the etiology of nasal polyps (NP). Infectious factors always play an important role in the pathogenesis of CRSwNP. The lesions of nasal polyp have different inflammatory cell infiltration and can be divided into two types in immunophenotpe: the first is characterized by Th2 cell reaction and marked eosinophil infiltration,and the second is Th1/Th17 cell response and non-eosinophil infiltration are characteristic.NP, which is mainly infiltrated by neutrophils, is more and more common in China. B cell activation factor (BAFF) is a major inflammatory factor related to the regulation of B cell activation.Recent experiments have shown that BAFF is also high in nasal polyps.In this paper, the effects and interactions of BAFF and eosinophils and neutrophils in CRSwNP were reviewed.

Abstract
Magnetism of Cu2(OH)3Br single crystals based on a triangular lattice is studied by means of magnetic susceptibility, pulsed-field magnetization, and specific heat measurements. There are two inequivalent Cu2+ sites in an asymmetric unit. Both Cu2+ sublattices undergo a long-range antiferromagnetic (AFM) order at [Formula: see text] K. Upon cooling, an anisotropy crossover from Heisenberg to XY behavior is observed below 7.5 K from the anisotropic magnetic susceptibility. The magnetic field applied within the XY plane induces a spin-flop transition of Cu2+ ions between 4.9 T and 5.3 T. With further increasing fields, the magnetic moment is gradually increased but is only about half of the saturation of a Cu2+ ion even in 30 T. The individual reorientation of the inequivalent Cu2+ spins under field is proposed to account for the magnetization behavior. The observed spin-flop transition is likely related to one Cu site, and the AFM coupling among the rest Cu spins is so strong that the 30 T field cannot overcome the anisotropy. The temperature dependence of the magnetic specific heat, which is well described by a sum of two gapped AFM contributions, is a further support for the proposed scenario.

Abstract
Aging is a risk factor for various acute and chronic kidney injuries. Kidney aging is accompanied by the secretion of growth factors, proteases, and inflammatory cytokines, known as the senescence-associated secretory phenotype (SASP). These factors accelerate the aging process and senescence-associated changes. Delaying kidney senescence may prevent acute and chronic kidney injury. Methionine restriction (MR) was found to be an effective intervention for delaying senescence. However, the mechanism of MR remains unclear. In this study, we investigated the effect of MR on the survival rate and renal aging of C57BL/6 mice and examined the relevant mechanisms. MR increased the survival rate and decreased the levels of senescence markers in the aging kidney. Both in vivo and in vitro, MR upregulated the transsulfuration pathway to increase H2S production, downregulated senescence markers and the SASP, and activated AMPK. The ability of MR to delay aging was reduced when AMPK was inhibited. These results suggest that MR may slow animal aging and kidney senescence through H2S production and AMPK pathway activation.

Abstract
Objective: To determine the association of serum fibroblast growth factor-23 concentrations with age-related cardiac diastolic function subclinical state and whether this association differs by sex. Methods: Seven hundred sixteen healthy subjects (aged 35-89 years, 68.4% female) were selected from National Basic Research Program of China (973 Program-China Medical University subsection) between January 2014 and February 2015 and assigned into 4 groups according to sex and age:< 60 years old male and female group, ≥ 60 years old male and female group. Blood biochemical indicators and general clinical data of the subjects were measured. The glomerular filtration rate (eGFR) were estimated using the Modified Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI-ASIA) equation. The fibroblast factor 23 (FGF-23), C-reactive protein (CRP) and interleukin-6 (IL-6) were measured by enzyme-linked immunosorbent assay (ELISA). Cardiac structure and function parameters including left atrial diameter (LAD), inter-ventricular septum thickness (IVST), left ventricle posterior wall thickness (LVPWT), left ventricle mass index (LVMI),left atrial mass index (LAVI) and the ratio of peak velocity of early filling to the septal early peak diastolic mitral annulus velocity(E/e') were measured by echocardiography. Association between serum FGF-23 and aging-related diastolic function subclinical status was analyzed by binary Logistic regression analysis. Results: (1) Serum log-transformed FGF-23 levels were significantly higher in males than in females [(2.0±0.3) ng/L vs (1.9±0.4) ng/L, P<0.05]. (2) Cardiac diastolic function gradually decreased with age, and age related cardiac diastolic function decline of female was significantly higher than males[E/e':<60 years old male group (7.6±2.6), ≥ 60 years old male group (8.6±2.7), P<0.01;<60 years old female group (8.3±2.3), ≥ 60 years old female group (9.5±3.1), P<0.01; LAVI:<60 years old female group (14±5) ml/m(2), ≥ 60 years old female group (16±5) ml/m(2), P<0.01]. (3) Serum FGF-23 was significantly positively correlated with age (r=0.089, P<0.05) and LAVI (r=0.084, P<0.05) in total study population while with E/e' (r=0.149, P<0.05) only in males. There was no significant correlation between serum FGF-23 and cardiac diastolic function parameters in females. (4) Binary Logistic regression analysis showed that median and high FGF-23 were independently associated with age-related cardiac diastolic function decline (OR=2.831, 95% CI: 1.144-7.009, P=0.024; OR=2.548, 95% CI: 1.053-6.163, P=0.038) in males. Conclusions: Serum FGF-23 concentrations are associated with age-related cardiac diastolic function subclinical state in a healthy Chinese population. High levels of FGF-23 are independently associated with age-related cardiac diastolic function decline in males.

Abstract
BACKGROUND Diastolic electromechanical couple, a well-described phenomenon in symptomatic heart failure, has not been well studied in healthy people. We hypothesized that ventricular repolarization variables, such as the QT interval, Tpeak-to-Tend (Tpe) interval and Tpe/QT ratio, are associated with cardiac diastolic function in the healthy Chinese population.
AIM To assess the relationship between ventricular repolarization variables and cardiac diastolic function in apparently healthy Chinese individuals.
METHODS This was a community-based cross-sectional study conducted in Shenyang, China. A total of 414 healthy subjects aged 35-91 years were enrolled. All subjects underwent standard 12-lead electrocardiography (ECG) and comprehensive echocardiography. ECG enabled the measurement of QT and Tpe intervals and Tpe/QT ratio. echocardiographic parameters, such as the ratio of mitral early diastolic inflow velocity (E) and late diastolic inflow velocity (A), E-wave deceleration time, left atrial volume (LAV) and LAV index, were measured to assess diastolic function. E/A < 0.75 was considered to indicate reduced diastolic function. ECG and echocardiography results were analyzed separately and in a blinded fashion. Correlation and regression analyses were applied to determine associations.
RESULTS Ventricular repolarization variables, such as the QTc interval (393.59 ± 26.74 vs 403.86 ± 33.56; P < 0.001), Tpe interval (72.68 ± 12.41 vs 77.26 ± 17.86; P < 0.01), Tpec interval (76.36 ± 13.53 vs 83.32 ± 21.25; P < 0.001) and Tpe/QT ratio (0.19 ± 0.03 vs 0.20 ± 0.04; P < 0.01), were significantly different between the normal diastolic function group and the reduced diastolic function group. Significant associations were found between repolarization variables and diastolic function. After adjusting for all other possible confounders, the QTc and Tpec intervals were significantly associated with the E/A ratio (P = 0.008; P = 0.010). In men, the QTc interval was associated with abnormal diastolic function, and compared to the third QTc tertile, in the second QTc tertile, the odds ratio was 0.257 (95%CI: 0.102–0.649; P = 0.004).
CONCLUSION Repolarization variables are associated with cardiac diastolic function even in healthy people. Moderate levels of the QTc interval exert a protective effect on diastolic dysfunction in men.
