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
Background: By implementing aggressive control measures, China has rapidly and effectively controlled the Coronavirus disease 2019 (COVID-19) pandemic. However, the neglected homeless population may become victims of that perceived success. Due to political sensitivity, we know little about them. Aims: This study aimed to investigate how the pandemic and the pandemic control strategies of the government affected the lives of the homeless people in mainland China. Methods: A total of 103 eligible participants experiencing absolute homelessness were recruited from Guangzhou City during July and August 2020. Surveys measured demographic characteristics including health status, changes in daily living, and actions of the government toward the homeless during the pandemic. Sankey diagrams and ordered logit regression models were used to examine the impact on the homeless of inhumane government efforts to drive the homeless away. Qualitative materials were analyzed by using an inductive approach to provide more details. Results: First, the homeless people in Guangzhou tended to be male, aged 40 to 64 years, less well-educated, and they originated from outside Guangdong although they were living in the city center. Most had little connection with their families. After a long period of homelessness, almost half of the participants were in poor health with various conditions, which made them extremely vulnerable to COVID-19. Second, the pandemic caused a substantial decline in incomes of homeless people, had less of a negative impact on their food intake, and affected sleep time in different ways. Third, during the COVID-19 pandemic, humanitarian aid from local governments of China decreased, whereas inhumane efforts to drive the homeless away intensified. Fourth, quantitative models and qualitative materials demonstrate the devastating effect of the strict pandemic control strategy of the government on the lives of homeless people, which may further cause their health problems. Conclusion: This study for the first time illustrated the characteristic features of the street homeless population in mainland China and their living situation during the COVID-19 pandemic, and most importantly demonstrated the devastating effect of the strict pandemic control of the government, which has been considered a great success in previous studies, on lives of homeless people. Urgent measures should be taken to ensure the protection of the homeless population and prevent an impending humanitarian crisis.

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
Gluten-containing grains cause adverse health effects in individuals with celiac disease. Fermentation of these grains results in gluten-derived polypeptides with largely uncharacterized sizes and sequences, which may still trigger an immune response. This research used N-terminal labeling mass spectrometry to characterize protein hydrolysates during each stage of bench-scale brewing, including malting, mashing, boiling, fermentation, and aging. Gluten hydrolysates from each brewing step were tracked, and the immunotoxic potential was evaluated by sequence comparison with peptides known to stimulate celiac immune responses. The results indicate that proteolysis and precipitation of gliadins occurring during brewing differ by protein region and brewing stage. The termini of gliadins were hydrolyzed throughout the entire brewing process, but the central regions remained relatively stable. Most hydrolysis occurred during malting, and most precipitation occurred during boiling. The addition of yeast yielded new cleavage sites but did not result in complete hydrolysis. Consistent detection of peptides within the clinically important regions of gliadin corroborated the hydrolytic resistance of this region. N-terminal labeling mass spectrometry served as a novel approach to track the fate of gliadin/gluten throughout bench-scale brewing. Consistently identified fragments could serve as improved targets for the detection of hydrolyzed gluten in fermented products.

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
The safety and regulatory status of fermented products derived from gluten-containing grains for patients with celiac disease remains controversial. Bottom-up mass spectrometry (MS) has complemented immunoassays for the compositional and immunogenic analyses of wheat beers. However, uncharacterized proteolysis during brewing followed by the secondary digestion for MS has made the analysis and data interpretation complicated. In this study, the composition and immunogenic potential of seven commercially available wheat beers were evaluated using bottom-up MS with the aid of fractionation and a multi-step peptide search strategy to identify peptides generated by various types of proteolysis. Gluten-derived peptides accounted for approximately 50% and 20% of the total number of wheat-derived and barley-derived peptides, respectively, in the investigated beers. Although relatively large polypeptides cannot be thoroughly characterized using traditional bottom-up proteomics, up to 50% of peptides identified contained celiac-immunogenic motifs, and consumption of wheat beers would pose risks for celiac patients.

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
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.

Abstract
Objective: To investigate the clinical and coagulation characteristics in patients with critical Coronavirus disease 2019 (COVID-19) and acro-ischemia. Methods: The retrospective study included 7 critical COVID-19 patients with acro-ischemia in an intensive care unit (ICU) in Wuhan, from Feb 4 to Feb 15, 2020. The clinical and laboratory data before and during the ICU stay were analyzed. Results: The median age of 7 patients was 59 years and 4 of them were men. Three patients were associated with underlying comorbidities. Fever, cough, dyspnea and diarrhea were common clinical symptoms. All patients had acro-ischemia presentations including finger/toe cyanosis, skin bulla and dry gangrene. D-dimer, fibrinogen and fibrinogen degradation product (FDP) were significantly elevated in most patients. Prothrombin time was prolonged in 4 patients. D-dimer and FDP levels progressively elevated consistent with COVID-2019 exacerbation. Four patients were diagnosed with disseminated intravascular coagulation (DIC) . Low molecular weight heparin (LMWH) was administrated in 6 patients, which reduced D-dimer and FDP rather than improved clinical symptoms. Five patients died finally and the median time from acro-ischemia to death was 12 days. Conclusions: Coagulation parameters should be monitored closely in critical COVID-2019 patients. The timing and protocol of anticoagulation therapy are still under investigation based on more clinical data.

Abstract
Data of physical measurement of children aged 7-17 years old in China was from National Nutrition and Health Survey in 1982, 1992, 2002 and 2010-2012. From 1982 to 2012, the height and weight of children aged 7-17 years old continued to increase. The height of urban boys, urban girls, rural boys and rural girls ranged from 118.8 to 171.1, 117.8 to 159.9, 113.3 to 168.2 and 111.7 to 158.1 cm, and weight ranged from 21.3 to 61.4, 20.2 to 53.1, 19.4 to 57.9, and 19.0 to 51.5 kg, respectively. The height and weight of urban children were larger than those of rural children. The height and weight of boys were larger than those of girls, except for adolescents. From 1982 to 2012, the height increment of urban boys, urban girls, rural boys and rural girls was 8.8, 6.2, 12.9 and 10.8 cm, and weight increment was 9.9, 6.2, 9.8 and 7.6 kg, respectively. The increment of urban children was smaller than that of rural children, which implied that the disparity between urban and rural was shrinking. The increment of boys was larger than that of girls, which implied that the gender disparity was increasing.
