Abstract
Memory has been identified as the least heritable cognitive trait in canines, suggesting a significant influence of non-genetic factors. We observed a trend that overall memory scores (OMS) improve with age in a cohort of 27 young dogs, but considerable plasticity exists. Employing linear discriminant analysis of gut microbiome data from dogs exhibiting low and high OMS, a single bacterial species, Bifidobacterium pseudolongum, was identified and confirmed to be correlated with elevated OMS. Subsequent analysis using a random forest regression model revealed that sex, litter, and breed identity had minimal predictive importance. Age had some predictive value but failed to achieve statistical significance in this dataset. In sharp contrast, the abundance of 17 bacterial taxa in the microbiome showed a stronger predictive capacity for memory performance. Our findings provide insights into microbiome underpinnings of mammalian cognitive functions and suggest avenues for developing psychobiotics to enhance canine memory and learning.

Abstract
MicroRNAs have been shown to potentially function in cerebral ischemia/reperfusion (IR) injury. This study aimed to examine the expression of microRNA-320 (miR-320) in cerebral IR injury and its involvement in cerebral mitochondrial function, oxidative stress, and inflammatory responses by targeting the HMGB1/NF-kappaB axis. Sprague-Dawley rats were subjected to middle cerebral artery occlusion to simulate cerebral IR injury. The cerebral expression of miR-320 was assessed using qRT-PCR. Neurological function, cerebral infarct volume, mitochondrial function, oxidative stress, and inflammatory cytokines were evaluated using relevant methods, including staining, fluorometry, and ELISA. HMGB1 expression was analyzed through Western blotting. The levels of miR-320, HMGB1, neurological deficits, and cerebral infarction were significantly higher after IR induction. Intracerebral overexpression of miR-320 resulted in substantial neurological deficits, increased infarct volume, elevated levels of 8-isoprostane, NF-kappaBp65, TNF-alpha, IL-1beta, ICAM-1, VCAM-1, and HMGB1 expression. It also promoted the loss of mitochondrial membrane potential and ROS levels while reducing MnSOD and GSH levels. Downregulation of miR-320 and inhibition of HMGB1 activity significantly reversed the outcomes of cerebral IR injury. MiR-320 plays a negative role in regulating cerebral inflammatory/oxidative reactions induced by IR injury by enhancing HMGB1 activity and modulating mitochondrial function.

Abstract
A 65-year-old male patient was admitted for recurrent lymph node enlargement for 5 years and elevated creatinine for 6 months. This patient was diagnosed with angioimmunoblastic T-cell lymphoma 5 years ago and underwent multiple lines of anti-tumor therapy, including cytotoxic chemotherapy; epigenetic modifying drugs such as chidamide and azacitidine; the immunomodulator lenalidomide; and targeted therapy such as rituximab, a CD20-targeting antibody, and brentuximab vedotin, which targets CD30. Although the tumor was considered stable, multiple virus activation (including BK virus, JC virus, and cytomegalovirus) accompanied by the corresponding organ damage (polyomavirus nephropathy, cytomegalovirus retinitis, and progressive multifocal leukoencephalopathy) occurred during anti-tumor treatment. Anti-tumor therapy was suspended and ganciclovir was used. The serum viral load decreased and organ functions were stabilized. The purpose of this report was to raise clinicians' awareness of opportunistic virus reactivation during anti-tumor treatment.

Abstract
PURPOSE Diabetes and dyslipidemia are among the most common chronic diseases with increasing global disease burdens, and they frequently occur together. The study aimed to investigate differences in the heritability of glycemic traits and serum lipid indicators and differences in overlapping genetic and environmental influences between them across age groups. METHODS This study included 1189 twin pairs from the Chinese National Twin Registry and divided them into three groups: aged ≤ 40, 41-50, and > 50 years old. Univariate and bivariate structural equation models (SEMs) were conducted on glycemic indicators and serum lipid indicators, including blood glucose (GLU), glycated hemoglobin A1c (HbA1c), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C), in the total sample and three age groups. RESULTS All phenotypes showed moderate to high heritability (0.37-0.64). The heritability of HbA1c demonstrated a downward trend with age (HbA1c: 0.50-0.79), while others remained relatively stable (GLU: 0.55-0.62, TC: 0.58-0.66, TG: 0.50-0.63, LDL-C: 0.24-0.58, HDL-C: 0.31-0.57). The bivariate SEMs demonstrated that GLU and HbA1c were correlated with each serum lipid indicator (0.10-0.17), except HDL-C. Except for HbA1c and LDL-C, as well as HbA1c and HDL-C, differences in genetic correlations underlying glycemic traits and serum lipids between age groups were observed, with the youngest group showing a significantly higher genetic correlation than the oldest group. CONCLUSION Across the whole adulthood, genetic influences were consistently important for GLU, TC, TG, LDL-C and HDL-C, and age may affect the shared genetic influences between glycemic traits and serum lipids. Further studies are needed to elucidate the role of age in the interactions of genes related to glycemic traits and serum lipids.

Abstract
The emerging two-dimensional (2D) semiconductors substantially extend materials bases for versatile applications such as semiconductor photocatalysis demanding semiconductive matrices and large surface areas. The dimensionality, while endowing 2D semiconductors the unique properties to host photocatalytic functionality of pollutant removal and hydrogen evolution, hurdles the activation paths to form heterogenous photocatalysts where the photochemical processes are normally superior over these on the mono-compositional counterparts. In this perspective, we present a cross-dimensional strategy to employ thenD (n= 0-2) clusters or nanomaterials as activation partners to boost the photocatalytic activities of the 2D semiconductors. The formation principles of heterogenous photocatalysts are illustrated specifically for the 2D matrices, followed by selection criteria of them among the vast 2D database. The computer investigations are illustrated in the density functional theory route and machine learning benefitted from the vast samples in the 2D library. Synthetic realizations and characterizations of the 2D heterogenous systems are introduced with an emphasis on chemical methods and advanced techniques to understand materials and mechanistic studies. The perspective outlooks cross-dimensional activation strategies of the 2D materials for other applications such as CO2removal, and materials matrices in other dimensions which may inspire incoming research within these fields.

Abstract
The study aimed to reveal for the first time the clinical characteristics, nutritional and metabolic status and support of hospitalized patients with common variant immunodeficiency disease (CVID), and provide reference to improve the long-term nutritional management for such patients. This is a retrospective cross-sectional study. Through searching the electronic medical record system of Peking Union Medical College Hospital, the study included 33 consecutive in-patients with CVID diagnosed in Jan 2016 to Jun 2021, with the male to female ratio of 16∶17. All their medical data, nutritional assessment and intervention retrospectively summarized and analyzed. Data with normal distribution were described using (x¯±s), and analyzed with independent sample t-test. Data with non-normal distribution were compared with non-parametric test. The results showed that the median onset-age of the included patients was 22 (10.0,36.5) years old, and the median duration was 9.0 (2.0,16.0) years. All patients had recurrent infections involving various systems (33/33), with development of autoimmune diseases (8/33) and lymphoproliferative disease or malignancy (9/33) in some cases among them. The nutritional risk screening 2002 (NRS 2002) scores revealed that 85.19% of adults had an NRS 2002≥3 points, and 33.33% of children had a BMI-for-age z score<-2. Weight loss occurred in 66.67% of patients (22/33), while 87.88% (29/33), 69.70% (23/33) and 81.82% (27/33) of patients respectively had anemia, hypoalbuminemia and decreased prealbumin. Among 22 patients with micronutrients status evaluated, 77.27% (17/22), 22.73% (5/22) and 31.82% (7/22) of patients respectively had lowered serum iron, folate deficiency and vitamin B12 insufficiency. Six patients underwent 25-OH-VD3 measurement, and were all testified to have vitamin D deficiency. Among all patients with nutritional risk, 56.00% of them underwent nutritional support: oral nutritional supplements (14 cases), enteral feeding (4 cases) and parenteral nutrition (5 cases). In conclusion, the condition of malnutrition was prevalent in patients with CVID, but was under-recognized and undertreated to some degree.

Abstract
PURPOSE/OBJECTIVE(S) The purpose of this study was to assess the treatment outcome and the potential prognostic factors for patients with stage I-II nasal ENKTL treated with radiotherapy (RT) combined chemotherapy (CT). MATERIALS/METHODS From July, 2005 to January, 2019, 118 eligible patients were retrospective included in the study. Among the 118 patients, 84 were male and 34 were female. The median age was 45 years (range: 14-77 years). According to the Ann Arbor staging system, 66 patients had stage I disease (Primary tumor invasion (PTI) was present in 29 patients), and 52 patients had stage II disease. B symptoms were observed in 61 patients. The Eastern Cooperative Oncology Group (ECOG) performance score was 0 to 1 in 88 patients. Cervical lymph node involvement was observed in 51 patients. The primary lesions were located in the nasal cavity in 92 cases and in the Waldeyer ring in 26 cases. Five patients had received RT followed by CT (RT + CT), 20 patients had received CT followed by RT (CT + RT), 90 patients had received CT followed by RT, again followed by CT (CT+RT+CT), and 3 patients had received concurrent chemoradiotherapy (CRT) (1 patient received CRT + CT, other 2 patients received CT+CRT+CT). Patients were irradiated with a median dose of 50 Gy (range, 24-61.2). All patients received chemotherapy, 91 received non-anthracycline-based chemotherapy, whereas 27 patients received anthracycline-based chemotherapy. The median number of courses of chemotherapy was four (range: 1-10). Patients were scored as having low-risk disease (n = 50), intermediate-risk disease (n = 60) or high-risk disease (n = 8) according to the prognostic index of natural killer cell lymphoma (PINK). RESULTS Among the 118 patients, after initial therapy, the complete response (CR) rate was 82.2% (n = 97), and the partial response (PR) rate was 11.0% (n = 13). The stable disease (SD) rate was 2.5% (n = 3), and the progressive disease (PD) rate was 4.2% (n = 5). With a median follow-up of 43 months (range, 4-201) after irradiation, the 3-year PFS and OS were 76.9% and 82.9%, respectively. The 3-year OS rate was 75.0% for RT + CT, 70.0% for CT + RT, 87.1% for CT + RT+ CT, and 50.0% for CRT (P = 0.052). Three-year OS and PFS were 88.6% and 83.4%, respectively, for non-anthracycline-based chemotherapy regimen compared to 61.6% (P = 0.001) and 58.4% (P = 0.003), respectively, for the anthracycline-based chemotherapy regimen. Three-year OS and PFS were 84.0% and 79.0%, respectively, for patients receiving high-dose RT (≥50 Gy, n = 111) compared to 71.4% (P = 0.076) and 71.4% (P = 0.228), respectively, for low-dose RT (<50 Gy, n = 7). In multivariate analysis, adverse factors associated with OS in our study were chemotherapy regimen and response to RT and CT (P = 0.047, <0.001). CONCLUSION Radiotherapy combined with chemotherapy reported promising response rate and a favorable survival for patients with stage I-II nasal ENKTL. Anthracycline-based chemotherapy regimen and no remission after RT and CT were adverse factors of OS.

Abstract
The objective of our study was to assess the effect of rumen-protected niacin supplementation on the transcriptome of liver tissue in growing Angus × Simmental steers and heifers through RNA-seq analysis. Consequently, we wanted to assess the known role of niacin in the physiological processes of vasodilation, detoxification, and immune function in beef hepatic tissue. Normal weaned calves (~8 months old) were provided either a control diet or a diet supplemented with rumen-protected niacin (6 g/hd/d) for a 30-day period, followed by a liver biopsy. We observed a significant list of changes at the transcriptome level due to rumen-protected niacin supplementation. Several metabolic pathways revealed potential positive effects to the animal's liver metabolism due to administration of rumen-protected niacin; for example, a decrease in lipolysis, apoptosis, inflammatory responses, atherosclerosis, oxidative stress, fibrosis, and vasodilation-related pathways. Therefore, results from our study showed that the liver transcriptional machinery switched several metabolic pathways to a condition that could potentially benefit the health status of animals supplemented with rumen-protected niacin. In conclusion, based on the results of our study, we can suggest the utilization of rumen-protected niacin supplementation as a nutritional strategy could improve the health status of growing beef cattle in different beef production stages, such as backgrounding operations or new arrivals to a feedlot.

Abstract
OBJECTIVE To explore the biomarkers of tinnitus in vestibular schwannoma patients using electroencephalographic (EEG) microstate technology. METHODS The EEG and clinical data of 41 patients with vestibular schwannoma were collected. All the patients were evaluated by SAS, SDS, THI and VAS scales. The EEG acquisition time was 10-15 min, and the EEG data were preprocessed and analyzed using MATLAB and EEGLAB software package. RESULTS Of the 41 patients with vestibular schwannoma, 29 patients had tinnitus and 12 did not have tinnitus, and their clinical parameters were comparable. The average global explanation variances of the non-tinnitus and tinnitus groups were 78.8% and 80.1%, respectively. The results of EEG microstate analysis showed that compared with those without tinnitus, the patients with tinnitus had an increased frequency (P=0.033) and contribution (P=0.028) of microstate C. Correlation analysis showed that THI scale scores of the patients were negatively correlated with the duration of microstate A (R=-0.435, P=0.018) and positively with the frequencies of microstate B (R=0.456, P=0.013) and microstate C (R=0.412, P=0.026). Syntax analysis showed that the probability of transition from microstate C to microstate B increased significantly in vestibular schwannoma patients with tinnitus (P=0.031). CONCLUSION EEG microstate features differ significantly between vestibular schwannoma patients with and without tinnitus. This abnormality in patients with tinnitus may reflect the potential abnormality in the allocation of neural resources and the transition of brain functional activity.

Abstract
Genomic imprinting is a parent-of-origin-specific expression phenomenon that plays fundamental roles in many biological processes. In animals, imprinting is only observed in therian mammals, with ∼200 imprinted genes known in humans and mice. The imprinting pattern in marsupials has been minimally investigated by examining orthologs to known eutherian imprinted genes. To identify marsupial-specific imprinting in an unbiased way, we performed RNA-seq studies on samples of fetal brain and placenta from the reciprocal cross progeny of two laboratory opossum stocks. We inferred allele-specific expression for >3,000 expressed genes and discovered/validated 13 imprinted genes, including three previously known imprinted genes, Igf2r, Peg10, and H19. We estimate that marsupials imprint ∼60 autosomal genes, which is a much smaller set compared with eutherians. Among the nine novel imprinted genes, three noncoding RNAs have no known homologs in eutherian mammals, while the remaining genes have important functions in pluripotency, transcription regulation, nucleolar homeostasis, and neural differentiation. Methylation analyses at promoter CpG islands revealed differentially methylated regions in five of these marsupial-specific imprinted genes, suggesting that differential methylation is a common mechanism in the epigenetic regulation of marsupial imprinting. Clustering and co-regulation were observed at marsupial imprinting loci Pou5f3-Npdc1 and Nkrfl-Ipncr2, but eutherian-type multi-gene imprinting clusters were not detected. Also differing from eutherian mammals, the brain and placenta imprinting profiles are remarkably similar in opossums, presumably due to the shared origin of these organs from the trophectoderm. Our results contribute to a fuller understanding of the origin, evolution, and mechanisms of genomic imprinting in therian mammals.

Abstract
This study aimed to explore the mechanism of Qingre Huoxue Fang (QRHXF) treatment on anti-angiogenesis in rheumatoid arthritis (RA) based on network pharmacology and in vitro experiments. We used the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and Therapeutic Target (TTD) database to extract the active components of QRHXF and potential targets for regulating angiogenesis. First, we used Cytoscape bioinformatics software to construct the network of QRHXF-angiogenesis and screened the potential targets. Then, we performed gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis on the potential core targets. In addition, enzyme-linked immune assay and Western blot were used for in vitro validation and to verify the effects of different concentrations of QRHXF on the expression levels of the vascular endothelial growth factor receptor type 1 (VEGFR-1) and VEGFR-2 cytokines and phosphoinositide 3-kinase (PI3k) and Ak strain transforming (Akt) proteins in human umbilical vein endothelial cells (HUVECs). In results, we screened 179 core QRHXF antiangiogenic targets, including vascular endothelial growth factor (VEGF) cytokines. Enrichment analysis showed that the targets were enriched in 56 core signaling pathways, including PI3k and Akt. In vitro experiments showed that the migration distance and square, adhesion optical density (OD) values, and the number of branch points in tube formation significantly decreased in the QRHXF group compared with the induced group (P<0.01). Notably, the serum levels of VEGFR-1 and VEGFR-2 were lower compared with the induced group (P<0.05 or P<0.01). In addition, the expressions of PI3K and p-Akt proteins were decreased in the middle- and high doses groups (P<0.01). This study's results suggest that the downstream mechanism of QRHXF anti-angiogenesis might inhibit the PI3K-Akt signalling pathway and downregulate VEGF-1 and VEGF-2.

Abstract
Introduction: Perfluoroalkyl and poly-fluoroalkyl substances (PFASs) are widely used in industrial and consumer products. Due to their environmental persistence and bioaccumulation, PFASs can be found in the blood of humans and wild animals all over the world. Various fluorinated alternatives such as GenX have been developed to replace the long-chain PFASs, but there is limited information about their potential toxicity. Methods:The current study developed blood culture protocols to assess the response to toxic compounds in the marsupial, Monodelphis domestica. After whole-blood culture conditions were tested and optimized, changes in gene expression in response to PFOA and GenX treatment were assessed. Results: More than 10,000 genes were expressed in the blood transcriptomes with and without treatment. Both PFOA and GenX treatment led to significant changes in the whole blood culture transcriptomes. A total of 578 and 148 differentially expressed genes (DEGs) were detected in the PFOA and GenX treatment groups, 32 of which overlapped. Pathway enrichment analysis revealed that DEGs involved in developmental processes were upregulated after PFOA exposure, while those enriched for metabolic and immune system processes were downregulated. GenX exposure upregulated genes associated with fatty acid transport pathways and inflammatory processes, which is consistent with previous studies using rodent models. Discussion: To our knowledge, this study is the first to investigate the effect of PFASs in a marsupial model. The findings provide supportive evidence for significant transcriptomic alterations, suggesting that this mammalian model may provide a mechanism for exploring the potential toxicity of PFOA and GenX.

Abstract
Objective: To analyze the daily drinking behavior and related factors of primary and middle school students in the Nutrition Improvement Program for Rural Compulsory Education Students (NIPRCES) pilot regions. Methods: Multi-stage stratified random cluster sampling method was used to select one to three national pilot counties in 22 provinces in central and western China where the NIPRCES was implemented in 2019. According to different feeding patterns, two primary schools and two middle schools were selected as key monitoring schools. One or two classes were selected from grade 3 to grade 9. The student questionnaire was used to collect the basic information and daily drinking behavior. Taking whether the drinking water ≥5 cups every day as the dependent variable, multivariate logistic regression model was used to analyze the related factors of drinking behavior among students. Results: A total of 27 374 students were included. On average, primary and middle school students in the regions where NIPRCES was implemented had 3.9 cups of water every day. Logistic regression model showed that boys (OR=1.230, P<0.001), primary school students (OR=1.379, P<0.001), father worked outside the home (OR=1.169, P<0.001), both parents worked outside the home (OR=1.228, P<0.001), non-resident students (OR=1.142, P<0.001), the school in the village (OR=1.638, P<0.001) or township (OR=1.358, P<0.001), school feeding (OR=1.252, P<0.001), the school building with flush toilets (OR=1.384, P<0.001) and the central regions (OR=1.300, P<0.001) students were more likely to drink ≥5 cups water every day. Conclusion: The water consumption of primary and middle school students in the pilot regions of NIPRCES is low, and their drinking behaviors are affected by many factors.

Abstract
BACKGROUND Fecal specimens are critical for disease screening, diagnosis, and gut microbiome research. For domestic cats, lubricants are often necessary to obtain a sufficient quantity of sample. However, the effect of lubrication on feline microbiome analysis has not been assessed. OBJECTIVES To evaluate if lubrication using mineral oil during cat feces sample collection affects the DNA extraction, metagenomic sequencing yield, and the microbial composition and diversity in subsequent gut microbiome analyses. ANIMALS Eight 6-year-old male, neutered, domestic short-haired cats housed in a research facility. METHODS Cohort study. The gut microbiomes were investigated for fecal sample collection with and without lubrication using whole-genome shotgun metagenomic sequencing. RESULTS Fecal specimens were collected using a fecal loop under sedation without lubrication and with mineral oil lubrication. There were no significant differences between the 2 groups in the microbial DNA yield in ng/mg fecal sample (75.75 [25.8-125.7] vs 60.72 [33.49-87.95], P = .95), metagenomic sequencing yield in Gbp (10.31 [6.29-14.32] vs 13.53 [12.04-15.02], P = .2), proportion of host contamination (0.1 [0.02-0.18] vs 0.15 [0-0.3], P = .84), relative taxonomy abundance (P > .8), or the number of microbial genes covered (408 132 [341 556-474 708] vs 425 697 [358 505-492 889], P = .31). CONCLUSIONS AND CLINICAL IMPORTANCE Fecal sampling with mineral oil lubrication did not change the microbial DNA extraction yield, metagenomic sequencing yield, level of host contamination, the microbial composition and diversity in subsequent gut microbiome analyses. Here we reported a proven cat-friendly protocol for fecal sample collection in clinical and research setting for gut microbiome analyses.

Abstract
Objective: To analyze the overweight and obesity status of students in the national pilot counties of the Nutrition Improvement Program for Rural Compulsory Education Students in 2019 and its associated factors. Methods: In 2019, a multi-stage cluster random sampling method was used to select about 40 students from each grade in primary and secondary schools in China's central and western regions where the Nutrition Improvement Program for Rural Compulsory Education Students was implemented. The height and weight of the children were measured using height or weight scales. The school questionnaire and county questionnaire were used to investigate the associated factors. A Chi-square test was used for comparison between groups. The logistic regression analysis was used to analyze the associated factors. Results: In 2019, the prevalence of overweight and obesity among rural primary and secondary school students aged 6-15 years in central and western China 2019 was 11.5%. It was higher for boys (13.1%) than that for girls (9.8%), higher in central (14.3%) than that in the west (9.9%) and higher for elementary school students (12.4%) than that for secondary school students (9.5%, all P<0.001). The logistic regression showed that boys (OR=1.388), primary school students (OR=1.271), students without other dietary subsidies(OR=1.037), schools in rural areas (OR=1.133), schools with enterprise-based feeding mode (OR=1.043), schools without the provision of lunch (OR=1.143), schools without the provision of dinner (OR=1.122), and schools without providing drinking water (OR=1.015) were positively associated with overweight and obesity among students (P<0.05). Schools with snack shops (OR=0.952) were negatively associated with overweight and obesity among students (P<0.001). Conclusion: A certain proportion of primary and secondary school students in rural areas of central and western China are overweight and obese. The prevalence is not only related to children's gender, school section and county area but also related to school meals, whether schools provide drinking water and other factors.

Abstract
A 50-year-old man was admitted to the Department of Rheumatology at Peking Union Medical College Hospital with rash for 6 months, and fever and hematuria for 5 months. The main clinical manifestations included fever, fatigue, purpura, hematuria and thrombocytopenia. He was positive for antinuclear antibody (ANA), anti-neutrophil cytoplasmic antibodies (ANCA) and rheumatoid factor (RF), and had low complement levels. Initial blood culture, echocardiography and chest CT showed no signs of infection. Diagnosis of connective tissue disease was made initially. His disease improved under treatment with glucocorticoids and immunosuppressive agents, but relapsed when glucocorticoids were tapered. After admission, the diagnosis was reconsidered, and infective endocarditis was finally diagnosed with repeated positive blood cultures and vegetations detected by transesophageal echocardiography. Amoxicillin and clavulanate potassium were initiated, and surgery was performed. His symptoms finally recovered gradually.

Abstract
Monkeypox is a rare infectious disease caused by the monkeypox virus, which used to occur endemically in central and western Africa. As of 25th May, a total of 219 recently confirmed cases of monkeypox have been reported from 19 non-endemic countries. This outbreak unusually takes place in non-endemic areas for monkeypox virus and has exhibited features of high risk of human-to-human transmission. Onset of multiple human monkeypox cases may be related to the decreased level of herd cross-immunity after the cessation of smallpox vaccination. Moreover, behavioral patterns in specific populations may account for the human-to-human transmission in this outbreak. Currently, possibility of global epidemic of monkeypox is extremely low, but China should be cautious about risks of importation of monkeypox cases. The key to prevention and control is to establish a surveillance system to identify suspicious cases and close contacts as soon as possible.

Abstract
This study aims to explore optimized teaching mode of cancer epidemiology for undergraduates, and provide scientific ideas and basis for improving teaching quality. Non-randomized concurrent control study was used. Undergraduates, enrolled in 2018, from the department of preventive medicine in A and B medical universities were selected as research objects. Traditional teaching mode was used for cancer epidemiology course in A medical university, and innovative teaching mode named "one core, four dimensions" was adopted in B medical university. After the course, questionnaire method was used to investigate self-cognition of students, teaching satisfaction and class preparation time of teachers in B Medical University. The post-class test method was used to compare the students' grades of cancer epidemiology in the two universities. The results indicated that among the 58 students of B medical university, 94.83% (55/58) students were familiar with common types of epidemiological studies and 86.21% (50/58) mastered the evaluation indicators of screening research. Among the nine teaching faculties from B medical university, seven reported that the new teaching plan helped students to learn frontier knowledge of cancer epidemiology, and eight reported the new teaching model was conducive to the interaction between teachers and students. The text score of students in B medical university was 50.34±4.90, significantly higher than that in A medical university (46.21±4.91, t=5.20, P<0.001). The optimized teaching mode of cancer epidemiology is highly praised by students and teachers, which has the potential to improve students' grasp of cancer epidemiology, the ability to combine theory with practice, and the teaching effect of cancer epidemiology.

Abstract
Objective: To investigate the clinical features and influencing factors of long-term prognosis of tuberculous meningitis(TBM), and to provide a recommendation for treatment and early intervention of TBM. Methods: Clinical data of TBM patients were retrospectively collected at Peking Union Medical College Hospital from January 2014 to December 2021. Patients who were followed-up more than one year were divided into two groups according to modified Rankin Scale (mRS). Risk factors associated with long-term prognosis were analyze by conditional logistic stepwise regression. Results: A total of 60 subjects were enrolled including 33 (55%) males and 27 (45%) females with age 15-79 (44.5±19.8) years. There were 30 cases (50%) complicated with encephalitis, 21 cases (35%) with miliary tuberculosis. The diagnosis was microbiologically confirmed in 22 patients (36.7%), including 5 cases (22.7%, 5/22) by acid-fast staining, 8 cases (36.4%, 8/22) by Mycobacterium tuberculosis (MTB) culture, and 20 cases (90.9%, 20/22) by molecular biology. The median follow-up period was 52(43, 66 ) months in 55 cases surviving more than one year. Among them, 40 cases (72.7%) were in favorable group (mRS 0-2) and 15 cases (27.3%) were in unfavorable group (mRS 3-6) with poor prognosis. The mortality rate was 20% (11/55). Elderly (OR=1.06, P=0.048 ) , hyponatremia(OR=0.81,P=0.020), high protein level in cerebrospinal fluid (CSF) (OR=3.32,P=0.033), cerebral infarction(OR=10.50,P=0.040) and hydrocephalus(OR=8.51,P=0.049) were associated with poor prognosis in TBM patients. Conclusions: The mortality rate is high in patients with TBM. Molecular biology tests improves the sensitivity and shorten the diagnosis time of TBM. Elderly, hyponatremia, high protein level in CSF, cerebral infarction and hydrocephalus are independent risk factors of long-term survival in TBM patients.

Abstract
Objective: To analyze anemia prevalence and its influencing factors of students involved in the Nutritional Improvement Program for Rural Compulsory Education Students in 2019. Methods: From the 2019 surveillance system of the Nutrition Improvement Program for Rural Compulsory Education Students, 47 297 primary and middle school students aged 6-17 were included in the study. Hemoglobin level was tested according to the criteria of WHO 2011. Anemia prevalence of different genders, ages, and regions was analyzed. Results: The average hemoglobin level was 135.19 g/L, with the prevalence of anemia as 8.7% in the children aged 6-17. The prevalence of anemia was 10.0% in girls, higher than that in boys (7.4%). The prevalence rates in western and central areas were 9.8% and 7.1%, respectively. From northwest, southwest, central and south, east, north to northeast areas of China, the anemia rate appeared gradually decreasing (10.2%, 9.7%, 8.3%, 7.5%, 5.7% and 3.5%). The anemia prevalence rates were 8.0%, 8.3%, and 10.9% in children from the 6-, 11-, and 14-17 years age groups, respectively. Logistic regression models revealed that students from schools not using catering software (OR=1.482, 95%CI:1.296-1.694,P<0.001), schools not serving lunch (OR=1.241, 95%CI:1.103-1.395,P<0.001), and from relatively low-income families (OR=1.297, 95%CI:1.211-1.389, P<0.001) showed as risk factors for anemia. After supplementing students' dietary factors, the results showed that students who ate meat three or more times a week had a lower risk of anemia (OR=0.907, 95%CI:0.832-0.989, P=0.026). Conclusions: The Nutritional Improvement Program for Rural Compulsory Education Students had an essential impact on improving the anemia prevalence of primary and middle school students. Family income, school location, economic factors, school feeding, and students' diet programs all impacted the prevalence of anemia.

Abstract
Objective: To understand the growth retardation among primary and secondary school students in areas covered by the Nutrition Improvement Program for Rural Compulsory Education Students and its influencing factors to provide evidence for improving the nutrition status of rural students in China. Methods: The multi-stage cluster random sampling method selected 1 550 969 primary and secondary school students aged 6-15 years from China's central and western regions. The ratio of male and female students was balanced. The height was measured, and the growth retardation of students was determined according to the Screening Criteria for School-age Children and Adolescents malnutrition (WS/T 456-2014), from the school and county questionnaire survey related factors. The number of cases and percentages described the growth retardation of students, and the χ2 test was used for comparison between groups. Binary logistic regression was used to analyze students' growth retardation factors. Results: In 2019, the growth retardation rate of primary and secondary school students in areas covered by the Nutrition Improvement Program for Rural Compulsory Education Students was 5.7% (88 631/1 550 969), the growth retardation rate in the western part (7.1%, 66 167/927 954) was higher than that in the central part (3.7%,19 511/533 973) with difference statistically significant (P<0.001). The growth retardation rate of the boys (6.3%,50 665/803 851) were higher than that of girls (5.1%, 37 966/747 118), the difference was statistically significant (P<0.001). The growth retardation rate of primary school students in central China was 3.9%(14 914/380 598), higher than that of junior middle school students (3.0%,4 597/153 375, P<0.001). In contrast, the growth retardation rate of the western junior high school students (7.2%, 21 494/297 217) were higher than that of elementary school students (7.1%, 44 673/630 737), with a difference statistically significant (all P=0.009). Multi-factor logistic regression results showed that, in high income area (OR=0.829, 95%CI: 0.816-0.842, P<0.001), parents providing part of the meal cost (OR=0.948, 95%CI: 0.931-0.965, P<0.001), enterprises providing meals (OR=0.845, 95%CI: 0.805-0.887, P<0.001), schools providing milk (OR=0.780, 95%CI: 0.767-0.793, P<0.001), health education courses (OR=0.702, 95%CI: 0.682-0.723, P<0.001) and other local nutrition improvement efforts (OR=0.739, 95%CI: 0.720-0.758, P<0.001) were negatively correlated with the occurrence of growth retardation, The growth retardation rate of the students was lower. Conclusions: There appeared significant regional, gender, and age differences in the growth retardation rate of primary and middle school students in areas covered by the Nutrition Improvement Program for Rural Compulsory Education Students. Appropriate food supply in schools, health education courses, and parental participation in nutritional improvement was related to children's lower growth retardation rate.

Abstract
Objective: To analyze the situation and influencing factors of school meals leftover among primary and secondary school students in the area of the Nutrition Improvement Program for Rural Compulsory Education Students, improve the quality of school meals, develop healthy dietary behavior, and reduce food waste. Methods: In 2019, among the 50 monitoring counties that implemented the Compulsory Education Student Nutrition Improvement Program, two primary schools and two junior schools were randomly selected according to different food supply patterns.This study randomly selected one or two classes from grade 3 to grade 9. Basic information and school meals of 26 778 students were collected by using a student questionnaire. Multivariate logistic regression was used to analyze the influencing factors of leftovers rate. Results: 54.93% (14 709) of students wasted school meals, in which the highest rate was the staple food, with the main reason as "not in favor". 11.87% (1 743) of the students wasted school meals 6-7 days a week, with 54.20% (7 957) of students wasted but in less amount. The leftover rate of staple food was the highest (29.78%), followed by vegetables and meat. The main reason of leftovers was that they didn't like this kind of food (33.52%). The rate of school meal waste was higher for girls (OR=1.19,95%CI:1.13-1.25), junior high school students (OR=1.17, 95%CI: 1.11-1.25), resident students (OR=1.06, 95%CI: 1.00-1.12), lower economic level (OR=1.06, 95%CI: 1.00-1.12), parents working outside their houses (OR=1.22, 95%CI: 1.13-1.30), health education classes (OR=1.70, 95%CI: 1.40-2.06), company-based meals (OR=1.89, 95%CI: 1.71-2.07) and school meals were not as good as home food(OR=1.89, 95%CI: 1.78-2.00)(P<0.05). Conclusions: It is common for poor rural primary and middle school students in central and western China to waste school meals, and the reasons were affected by many factors. Reducing food waste requires the joint efforts of individuals, families, schools and society.

Abstract
Objective: To study the effect of anti-fibrotic tetrapeptide N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) on phosphorylated heat shock protein 27 (P-HSP27) and zinc finger family transcriptional repressor 1 (SNAI1) expression to explore the anti-silicosis fibrosis effect of Ac-SDKP. Methods: In December 2014, the rat silicosis animal model was prepared by one-time bronchial infusion of silicon dioxide (SiO(2)) dust. 80 SPF healthy adult Wistar rats were selected, and the rats were divided into 8 groups according to the random number table method, 10 in each group. Model control group for 4 weeks (feeding for 4 weeks) , model control group for 8 weeks (feeding for 8 weeks) : bronchial perfusion with normal saline 1.0 ml per animal. Silicosis model group for 4 weeks (feeding for 4 weeks) and silicosis model group for 8 weeks (feeding for 8 weeks) : bronchial perfusion of 50 mg/ml SiO(2) suspension 1.0 ml per animal. Ac-SDKP administration group for 4 weeks (feeding for 4 weeks) , Ac-SDKP administration group for 8 weeks (feeding for 8 weeks) : Ac-SDKP 800 μg·kg(-1)·d(-1) was administered by intraperitoneal pump. Ac-SDKP preventive treatment group: 48 h after Ac-SDKP 800 μg·kg(-1)·d(-1) administration, bronchial perfusion of SiO(2) suspension 1.0 ml per animal, raised for 8 weeks. Ac-SDKP anti-fibrosis treatment group: after bronchial perfusion of 1.0 ml of SiO(2) suspension for 4 weeks, Ac-SDKP 800 μg·kg(-1)·d(-1) was administered for 4 weeks. Western blotting was used to detect the expression of P-HSP27, SNAI1, α-smooth muscle actin (α-SMA) , and collage typeⅠ and Ⅲ in each group. The expression of P-HSP27 and SNAI1 was detected by immunohistochemistry, and the co-localized expression of P-HSP27 and α-SMA was detected by laser confocal microscopy. Results: Compared with the model control group, the expressions of P-HSP27, SNAI1, α-SMA, and collage typeⅠ and Ⅲ in the silicosis fibrosis area of the rats in the silicosis model group were enhanced, and the differences were statistically significant (P<0.05) . After Ac-SDKP intervention, compared with silicosis model group for 8 weeks, the expressions of P-HSP27, SNAI1 α-SMA, and collage typeⅠ and Ⅲ in the Ac-SDKP preventive and anti-fibrosis treatment groups were significantly decreased, and the differences were statistically significant (P<0.05) . However, the expressions of P-HSP27 SNAI1, and collage typeⅠ and Ⅲ between the Ac-SDKP administration group and the model control group did not change significantly, and the differences were not statistically significant (P>0.05) . Laser confocal results showed that the positive cells expressing P-HSP27 and α-SMA in the lung tissue of the silicosis model group were more than those in the model control group. Compared with the silicosis model group, the Ac-SDKP prevention and anti-fibrosis treatment groups expressing the positive cells of P-HSP27 and α-SMA decreased. Compared with the model control group for 8 weeks, there were some double-positive cells expressing P-HSP27 and α-SMA in the nodules of the silicosis model group for 8 weeks. Conclusion: Ac-SDKP may play an anti-silicic fibrosis effect by regulating the P-HSP27/SNAI1 pathway.

Abstract
Prostate cancer (PC) is one of the malignant tumors of the genitourinary system that occurs more often in elderly men. Screening, early diagnosis, and treatment of the PC high risk population are essential to improve the cure rate of PC. The development of the guideline for PC screening and early detection in line with epidemic characteristics of PC in China will greatly promote the homogeneity and quality of PC screening. This guideline was commissioned by the Bureau of Disease Control and Prevention of the National Health Commission. The National Cancer Center of China initiated and convened a working group comprising multidisciplinary experts. This guideline strictly followed the World Health Organization Handbook for Guideline Development and combined the most up-to-date evidence of PC screening, China's national conditions, and practical experience in cancer screening. A total of fifteen detailed evidence-based recommendations were provided with respect to the screening population, technology, procedure management, and quality control in the process of PC screening. This guideline aimed to standardize the practice of PC screening and improve the effectiveness and efficiency of PC prevention and control in China.

Abstract
Black yeasts are a phylogenetically diverse group of ascomycetous fungi that may exist in both unicellular and mycelial morphs. This group of fungi contains numerous commercially significant species as well as others whose precise roles are unknown, such as endolichenic species. There is currently a paucity of data about endolichenic black yeast species. To bridge this gap, we surveyed China’s Inner Mongolia Autonomous Region in July 2019. Several fungal species associated with diverse lichens were isolated during this survey. Among these were two isolates of a previously unknown species of oleaginous black yeast from Mycosphaerellales. Analyses of morphological and molecular data revealed that these two isolates were closely related to Xenodevriesia strelitziicola (Xenodevriesiaceae), although with significant differences. As a result, we established the genus Melanodevriesiagen. nov. to describe this previously unknown species, Melanodevriesia melanelixiaesp. nov. In addition, we used Transmission Electron Microscopy to visualise the intracellular oil bodies metabolised by this fungus in its unicellular state. The black yeast species identified in this study may have a wide range of commercial applications. More research is needed to determine the chemical composition of the microbial oil synthesized by this fungus and whether it has commercial value.

Abstract
The gray short-tailed opossum (Monodelphis domestica) is an established laboratory-bred marsupial model for biomedical research. It is a critical species for comparative genomics research, providing the pivotal phylogenetic outgroup for studies of derived vs ancestral states of genomic/epigenomic characteristics for eutherian mammal lineages. To characterize the current genetic profile of this laboratory marsupial, we examined 79 individuals from eight established laboratory strains. Double digest restriction site-associated DNA sequencing and whole-genome resequencing experiments were performed to investigate the genetic architecture in these strains. A total of 66,640 high-quality single nucleotide polymorphisms (SNPs) were identified. We analyzed SNP density, average heterozygosity, nucleotide diversity, and population differentiation parameter Fst within and between the eight strains. Principal component and population structure analysis clearly resolve the strains at the level of their ancestral founder populations, and the genetic architecture of these strains correctly reflects their breeding history. We confirmed the successful establishment of the first inbred laboratory opossum strain LSD (inbreeding coefficient F > 0.99) and a nearly inbred strain FD2M1 (0.98 < F < 0.99), each derived from a different ancestral background. These strains are suitable for various experimental protocols requiring controlled genetic backgrounds and for intercrosses and backcrosses that can generate offspring with informative SNPs for studying a variety of genetic and epigenetic processes. Together with recent advances in reproductive manipulation and CRISPR/Cas9 techniques for Monodelphis domestica, the existence of distinctive inbred strains will enable genome editing on different genetic backgrounds, greatly expanding the utility of this marsupial model for biomedical research.

Abstract
Spherical crystallization is a promising process intensification technique, where surfactant is an important ingredient in formulation but needs to be used carefully due to toxicological reasons. This work proposes to adopt colloidal particles stabilized Pickering emulsions for spherical crystallization, in order to eliminate or reduce the surfactant use. A representative system is selected for study, where silica nanoparticles are prepared to stabilize emulsions and evaporative crystallization of ibuprofen is carried out. Depletion attraction is exploited to improve the Pickering emulsion stability for better confining on crystallization with two depletants PEG and PVA tested. Crystal products from the emulsions prepared with silica nanoparticles and the non-ionic surfactant Tween 20 are compared. The results show that depletion attraction is helpful for producing stable Pickering emulsions with high dispersed phase fraction and mono-dispersed ibuprofen spherical agglomerates. Silica nanoparticles contribute to reduced induction time by boosting heterogeneous nucleation and mitigate secondary agglomeration possibly by steric effects.

Abstract
OBJECTIVE In many cancers, long non-coding RNAs (lncRNA) are largely involved; they can regulate cell proliferation, migration, and invasion. However, the research of lncRNA regulation on pancreatic ductal adenocarcinoma is vacant. The aim of this article was to lucubrate the specific role of lncRNA LUCAT1 in regulating the progression of pancreatic cancer. PATIENTS AND METHODS Pancreatic cancer and adjacent tissues were collected, and the expression of LUCAT1, one potential involved LucRNA, was measured using real-time qPCR (RT-qPCR). Different pathological types of pancreatic cancer cell lines were cultured, and the expression difference of LncRNA LUCAT1 was detected by RT-qPCR, and two cell lines were selected for downstream experiments. si-RNA was used to knockdown the expression of LUCAT1, comparing the difference in expression of LUCAT1, characterizing cell proliferation by MTT and BrdU staining, detecting apoptosis, and cell cycle changes by flow cytometry. Meanwhile, Western blotting was used for the detection of cyclin expression and thus investigate two important associated signaling pathways. Besides, the expression of signaling pathway was validated by signaling inhibitor. RESULTS In comparison to normal cells, LUCAT1 was highly expressed in human pancreatic cancer cell lines (p<0.05). The higher expression of LUCAT1 resulted in enhanced pathogenesis of PDA cells and motivated the development to S phase by regulation of cyclin D1, CDK4. Furthermore, LUCAT1 promoted PDA cells development by inducing AKT's and p38 MAPK's phosphorylation. CONCLUSIONS LUCAT1, as the key factor, played a positive role in the proliferation and invasion of pancreatic cells via AKT/MAPK signaling.

Abstract
Despite their partial ionic nature, many layered diatomic crystals avoid internal electric polarization by forming a centrosymmetric lattice at their optimal van-der-Waals stacking. Here, we report a stable ferroelectric order emerging at the interface between two naturally-grown flakes of hexagonal-boron-nitride, which are stacked together in a metastable non-centrosymmetric parallel orientation. We observe alternating domains of inverted normal polarization, caused by a lateral shift of one lattice site between the domains. Reversible polarization switching coupled to lateral sliding is achieved by scanning a biased tip above the surface. Our calculations trace the origin of the phenomenon to a subtle interplay between charge redistribution and ionic displacement, and provide intuitive insights to explore the interfacial polarization and its unique "slidetronics" switching mechanism.

Abstract
Objective: To analyze the compliance and related factors of low-dose computed tomography (LDCT) screening among the high-risk population of lung cancer in three provinces participating in the cancer early diagnosis and early treatment program in urban areas of China. Methods: From October 2017 to October 2018, 17 983 people aged between 40 and 74 years old at high risk of lung cancer were recruited from Zhejiang, Anhui and Liaoning provinces. The basic demographic characteristics, living habits, history of the disease and family history of cancer were collected by using a cancer risk assessment questionnaire, and the data of participants examined by LDCT were obtained from the hospitals participating in the program. The screening compliance was quantified by the screening participation rate, and it was calculated as the proportion of participants completing LDCT scan among high-risk population. The related factors of LDCT screening compliance were analyzed by using a multivariate logistic regression model. Results: The age of 17 983 participants was (56.52±8.22) years old. Males accounted for 51.9% (N=9 332), and 69.5% (N=12 495) had ever smoked, including former smokers and current smokers. A total of 6 269 participants were screened by LDCT, and the screening participation rate was 34.86%. The results of multivariate logistic regression analysis showed that the age group of 50 to 69 years old, female, passive smokers, alcohol consumption, family history of lung cancer and history of chronic respiratory diseases were more likely to be screened by LDCT, while the compliance of LDCT screening in current smokers was low. Conclusions: The LDCT screening compliance of the high-risk population of lung cancer in urban areas of China still needs to be improved. Age, sex, smoking, drinking, family history of lung cancer and history of chronic respiratory disease are associated with screening compliance.

Abstract
BACKGROUND Antimicrobial resistance is a growing concern in canine Staphylococcus pseudintermedius dermatitis. Treatment with rifampicin (RFP) is considered only in meticillin-resistant and multidrug-resistant S. pseudintermedius (MDR-MRSP). HYPOTHESIS/OBJECTIVES To determine an optimal RFP dosing for MDR-MRSP treatment without induction of RFP resistance and identify causal mutations for antimicrobial resistance. METHODS AND MATERIALS Time-kill assays were performed in a control isolate and three MDR-MRSP isolates at six clinically relevant concentrations [32 to 1,024 × MIC (the minimum inhibitory concentration)]. Whole-genome resequencing and bioinformatic analysis were performed in the resistant strains developed in this assay. RESULTS The genomic analysis identified nine antimicrobial resistance genes (ARGs) in MDR-MRSP isolates, which are responsible for resistance to seven classes of antibiotics. RFP activity against all four isolates was consistent with a time-dependent and bacteriostatic response. RFP resistance was observed in six of the 28 time-kill assays, including concentrations 64 × MIC in MDR-MRSP1 isolates at 24 h, 32 × MIC in MDR-MRSP2 at 48 h, 32 × MIC in MDR-MRSP3 at 48 h and 256 × MIC in MDR-MRSP3 at 24 h. Genome-wide mutation analyses in these RFP-resistant strains discovered the causal mutations in the coding region of the rpoB gene. CONCLUSIONS AND CLINICAL RELEVANCE A study has shown that 6 mg/kg per os results in plasma concentrations of 600-1,000 × MIC of S. pseudintermedius. Based on our data, this dose should achieve the minimum MIC (×512) to prevent RFP resistance development; therefore, we recommend a minimum daily dose of 6 mg/kg for MDR-MRSP pyoderma treatment when limited antibiotic options are available.

Abstract
ABSTRACT The function and protection of the parathyroid glands are increasingly popular research topics. New Zealand white rabbits are the most commonly used animal model of parathyroid ischemia. However, information on the vasculature of their parathyroid glands is limited. We used 94 healthy New Zealand white rabbits, 3-4 months of age and 2-3kg in weight, for exploration of the parathyroid glands, which were stained using hematoxylin and eosin (HE) after removal. The following types were classified according to the relationship between the position of the inferior parathyroid gland and the thyroid: Type A, Close Type, Type B, and Distant Type. There were 188 cases, 4 where the inferior parathyroid glands were located near the dorsal side of thyroid (2.13%), 8 where the inferior parathyroid glands were located superior to the upper pole of the thyroid (4.26%), 20 where the inferior parathyroid glands were located parallel to the thyroid (10.64%), and 155 cases where the inferior parathyroid glands were located inferior to the lower pole of thyroid (82.45%). Identifying the location and classifying the vasculature of the parathyroid glands in New Zealand white rabbits will provide an anatomical model to assist in future research.

Abstract
OBJECTIVE To uncover the role of microvesicle-containing (MV-containing) miRNA-153-3p in inducing the apoptosis of proximal tubular epithelial cells and RIF (renal interstitial fibrosis), and its potential mechanism. MATERIALS AND METHODS Mice were subjected to unilateral ureteral obstruction (UUO) to establish the in vivo RIF model. MVs were extracted from the obstructed kidney tissues of mice, to further isolate the RNAs. MiRNA-153-3p levels in RIF mice and MVs were determined. In vitro RIF model was constructed by TGF-β1 induction in NRK-52E and NRK-49F cells. The regulatory effect of miRNA-153-3p on the apoptosis of tubular epithelial cells was examined. Subsequently, potential target gene of miRNA-153-3p was predicted and identified. Rescue experiments were finally carried out to uncover the role of miRNA-153-3p/Bcl-2 in influencing RIF. RESULTS MiRNA-153-3p was upregulated in mice undergoing UUO, MVs extracted from obstructed kidney tissues of mice and TGF-β1-induced NRK-52E and NRK-49F cells. The overexpression of miRNA-153-3p remarkably induced apoptosis in tubular epithelial cells. Bcl-2 was verified to be the target gene of miRNA-153-3p, and the Bcl-2 level was negatively regulated by miRNA-153-3p. Overexpression of Bcl-2 reversed the effect of miRNA-153-3p on inducing cell apoptosis. CONCLUSIONS MV-containing miRNA-153-3p released by tubulointerstitial fibroblasts transmits to the proximal tubular epithelial cells via the damaged tubule basement membrane. It induces the apoptosis of proximal tubular epithelial cells by inhibiting Bcl-2 level and further aggravates RIF.

Abstract
Wolbachia are widespread intracellular bacteria that mediate many important biological processes in arthropod species. In this study, we identified 210 conserved single-copy genes in 33 genome-sequenced Wolbachia strains in the A–F supergroups. Phylogenomic analyses with these core genes indicate that all 33 Wolbachia strains maintain the supergroup relationship, which was classified previously based on the multilocus sequence typing (MLST) genes. Using an interclade recombination screening method, 14 inter-supergroup recombination events were discovered in six genes (2.9%) among 210 single-copy orthologs. This finding suggests a relatively low frequency of intergroup recombination. Interestingly, they have occurred not only between A and B supergroups (nine events) but also between A and E supergroups (five events). Maintenance of such transfers suggests possible roles in Wolbachia infection-related functions. Comparisons of strain divergence using the five genes of the MLST system show a high correlation (Pearson correlation coefficient r = 0.98) between MLST and whole-genome divergences, indicating that MLST is a reliable method for identifying related strains when whole-genome data are not available. The phylogenomic analysis and the identified core gene set in our study will serve as a valuable foundation for strain identification and the investigation of recombination and genome evolution in Wolbachia.

Abstract
OBJECTIVE To investigate the effect of miR-875 on the proliferation and apoptosis of non-small cell lung cancer (NSCLC) cancer cell line A549 and the related mechanism. PATIENTS AND METHODS 30 paired tumor tissue and the adjacent tissue were collected. Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) has been performed to detect the expression of miR-875 in NSCLC tissues and adjacent normal tissues. Moreover, suppressor of cytokine signaling 2 (SOCS2) has been predicted as a target of miR-875, and Dual-Luciferase reporter assay has been performed to confirm the targeting relationship; furthermore, the expression of SOCS2 in tumor tissue and the adjacent tissue were compared. Next, human NSCLC cell line A549 cells were cultured and transfected with miR-875 inhibitor with or without SOCS2 siRNA, and the proliferation and apoptosis of the cells were evaluated by Cell Counting Kit (CCK-8) and flow cytometry methods. Finally, the relative protein expression of Wnt and β-catenin were analyzed by Western blot analysis. RESULTS MiR-875 was significantly up-regulated in NSCLC tissues compared with the adjacent tissues. SOCS2 was confirmed as a target of miR-875, and the expression of SOCS2 was markedly decreased in NSCLC tissues. Moreover, the knockdown of miR-875 inhibited the proliferation and promoted the apoptosis of A549 cells, while transfection of SOCS2 siRNA can block miR-875 inhibitor-induced anti-proliferative effects. Finally, the transfection of miR-875 inhibitor decreased the expression of Wnt and β-catenin, and SOCS2 siRNA can reverse the effect. CONCLUSIONS MiR-875 may regulate the proliferation and apoptosis of NSCLC cells via targeting SOCS2, suggesting that miR-875 has the potential to become a therapeutic target for the treatment in NSCLC.

Abstract
OBJECTIVE Recently, long noncoding RNAs (lncRNAs) have got much attention for their role in tumor progression. LncRNA small nucleolar RNA host gene 7 (SNHG7) was studied in this research to identify how it affects the development of thyroid cancer (TC). PATIENTS AND METHODS SNHG7 expression was detected by quantitative Real-time polymerase chain reaction (qRT-PCR) in both TC cells and tissue samples. Pearson's Chi-square test was used to determine the association of SNHG7 expression with several clinicopathological factors. Moreover, colony formation assay, cell proliferation and cell apoptosis assay were conducted. In addition, by performing qRT-PCR and Western blot assay, the underlying mechanism was explored. RESULTS SNHG7 expression level was higher in TC samples than that in corresponding ones. The SNHG7 expression was associated with tumor size and TNM stage. Moreover, TC cell proliferation was inhibited, and TC cell apoptosis was induced after SNHG7 was knocked down in vitro. Moreover, the mRNA and protein expressions of brain-derived neurotrophic factor (BDNF) were downregulated after knockdown of SNHG7. Furthermore, the expression level of BDNF was positively related to the expression of SNHG7 in TC tissues. CONCLUSIONS These results suggested that knockdown of SNHG7 could inhibit TC cell proliferation and induce cell apoptosis via downregulating BDNF, which might be a potential therapeutic target in TC.

Abstract
BACKGROUND AND PURPOSE Thrombectomy up to 24 hours after stroke onset in patients with specific ischemic brain volumes remains a challenge, because many stroke centers do not apply specialized software to calculate ischemic volumes at advanced imaging. We aimed to establish the association between relative filling time delay on CTP source imaging and ischemic volume parameters and the infarct penumbra to core volume mismatch in patients with acute ischemic stroke. MATERIALS AND METHODS Consecutive patients with acute ischemic stroke and with M1 segment MCA with or without terminal ICA occlusions on baseline CTA and CTP within 24 hours of stroke symptom onset were included. Ischemic volumes were analyzed with software based on CTP maps. Relative filling time delay was classified into 4 grades-grade 0: relative filling time delay = 0 seconds; grade 1: relative filling time delay >0 to ≤4 seconds; grade 2: relative filling time delay >4 to ≤8 seconds; and grade 3: relative filling time delay > 8 seconds. Differences in ischemic volume parameters among relative filling time delay grades were tested. RESULTS We recruited 138 patients (median age, 69 years; 62.3% male). Different median volumes of the infarct core (grade 0, 7.3 mL; grade 1, 23.3 mL; grade 2, 45.7 mL; grade 3, 135 mL [P < .001]) and the penumbra (grade 0, 47.6 mL; grade 1, 90 mL; grade 2, 110 mL; grade 3, 92 mL [P = .043]) were observed among relative filling time delay grades. Target mismatch (defined by the criteria of the DEFUSE 3 trial) was identified in 71.7% of the patients (99/138). A relative filling time delay grade ≤ 1 independently predicted target mismatch, with a sensitivity of 0.79 (95% CI, 0.7-0.87) and a specificity of 0.66 (95% CI, 0.49-0.8). CONCLUSIONS Relative filling time delay grade based on CTP source imaging is a simple and effective parameter for evaluating ischemic volumes and target mismatch in patients with acute ischemic stroke. Further studies that compare relative filling time delay grade with clinical functional outcomes are necessary.

Abstract
OBJECTIVE Glioma is among the most aggressive of all human malignancies. Long non-coding RNA (lncRNA) gastric carcinoma highly expressed transcript 1 (GHET1) was considered an important oncogene in tumors. However, the role of GHET1 in glioma was rarely studied. The present work aimed to explore the effect of GHET1 on glioma cell line U251. MATERIALS AND METHODS The viability, migration and invasion of U251 cells were analyzed by Cell Counting Kit-8 (CCK-8) assay, and transwell migration/invasion assay, respectively. The relative expression of GHET1 and miR-216a were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The expression of cell cycle-related proteins, cell metastasis-associated proteins and main factors in the JAK2/STAT3 and p53/survivin pathways was analyzed by Western blot. Cell transfection assay was conducted to alter expression of GHET1 and miR-216a in U251 cells. RESULTS The viability, migration and invasion of U251 cells were promoted by GHET1 overexpression. The pro-cell cycle genes including Cyclin D1, CDK4 and CDK6, and the pro-metastasis genes including MMP-9 and Vimentin were up-regulated after GHET1 was overexpressed. MiR-216a was found to be down-regulated by GHET1 overexpression, and it was involved in the effects of GHET1 on U251 cells. GHET1 might promote U251 cells by down-regulating miR-216a. Finally, we found that GHET1 overexpression activated the JAK2/STAT3 and p53/survivin signaling pathways by down-regulating miR-216a. CONCLUSIONS GHET1 overexpression increased viability, migration and invasion of U251 cells by down-regulating miR-216a. Mechanically, GHET1-miR-216a axis activated the JAK2/STAT3 and p53/survivin signaling pathways.

Abstract
Chronic glomerulonephritis (CGN) is a disease with a steadily progressing course, which is based on inflammation with the activation of immune cells. The severity of the inflammatory reaction in the kidney tissue is determined by the balance of locally pro-inflammatory factors and protective mechanisms, which include anti-inflammatory cytokines and T-regulatory lymphocytes (Treg). The study of processes that can modulate the severity of inflammation in the kidney is of particular interest for understanding the basic patterns of CGN progression. AIM To determine the clinical significance of the Th17, Th1, and Treg cytokines in urine to assess the activity and progression of chronic glomerulonephritis with nephrotic syndrome (NS). MATERIALS AND METHODS The study included 98 patients with CGN 37 women and 61 men. Patients were divided into two groups according to the degree of CGN activity. Group I consisted of 51 patients with NS. In 21 subjects, a decrease in GFR60 ml/min was revealed. Group II included 47 patients with proteinuria from 1 to 3 g/day without NS. GFR60 ml/min/1.73 m2 was observed in 26 patients. A kidney biopsy was performed in 65 patients and the hystological diagnosis was verified: 20 had mesangioproliferative GN, 16 had membranous nephropathy, 18 had focal segmental glomerulosclerosis, and 11 had membranoproliferative GN. The control group consisted of 15 healthy people. The levels of IL-6, IL-10, IL-17, tumor necrosis factor a (TNF-a) in the urine were determined using enzyme-linked immunosorbent assay. The number of FoxP3-positive cells in the inflammatory interstitial infiltrate of the cortical layer was determined in 39 patients (in a biopsy sample in a 1.5 mm2 area). RESULTS In group of patients with CGN, there was an increase in the levels of Th17, Th1, and Treg cytokines in urine TNF-a and IL-10 compared with healthy individuals. An increase in the levels of IL-6 in the urine of patients with high clinical activity of CGN (with NS and renal dysfunction) was more pronounced than in patients with NS and normal renal function. There was a decrease in the number of Treg cells in the interstitium of the kidney and a decrease in the production of anti-inflammatory IL-10 in CGN patients with NS, compared with patients without NS. The most pronounced changes in the cytokine profile were observed in patients with FSGS with an increase in pro-inflammatory cytokines and a decrease in Treg in the kidney tissue/anti-inflammatory IL-10 in the urine. CONCLUSION An imbalance of cytokines characterized by an increased levels of pro-inflammatory IL-17, IL-6, TNF-a, and a reduced levels of anti-inflammatory IL-10 and T-regulatory cells in the kidney tissue is noted in patients with NS, especially with FSGS. Imbalance of cytokines reflects the high activity of CGN and the risk of the progression of the disease.
