Abstract
BACKGROUND Structural variations (SVs, defined as DNA variants ≥50 bp) have been associated with various complex human diseases. However, research to screen the whole genome for SVs predisposing to psoriasis is still lacking. OBJECTIVES This study aimed to investigate the association of SVs and psoriasis. METHODS We performed a genome-wide screen on SVs using an imputation method on 5 independent cohorts with 45,386 subjects from the Chinese Han population. Fine mapping analysis, genetic interaction analysis and RNA expression analysis were conducted to explore the mechanism of SVs. RESULTS We obtained 4,535 SVs in total and identified 2 novel deletions (esv3608550, OR=2.73, P<2.00×10-308 ; esv3608542, OR=0.47, P=7.40×10-28 ) at 6q21.33 (MHC), 1 novel Alu element insertion (esv3607339, OR=1.22, P=1.18×10-35 ) at 5q33.3 (IL12B), and confirmed 1 previously reported deletion (esv3587563, OR=1.30, P=9.52×10-60 ) at 1q21.2 (LCE) for psoriasis. Fine mapping analysis including SNPs and small Insertions/Deletions (InDels) revealed that esv3608550 and esv3608542 were independently associated with psoriasis, and a novel independent SNP (rs9378188, OR=1.65, P=3.46×10-38 ) was identified at 6q21.33. By genetic interaction analysis and RNA expression analysis, we speculate that the association of 2 deletions at 6q21.33 with psoriasis might relate to their influence on the expression of HLA-C. CONCLUSIONS Our study constructed the most comprehensive SV map for psoriasis thus far and enriched the genetic architecture and pathogenesis of psoriasis as well as highlighted the nonnegligible impact of SVs on complex diseases.

Abstract
OBJECTIVE Cancer susceptibility 19 (CASC19), a crucial lncRNA associated with multiple cancers, has been reported to play a vital role in the progression of human malignant tumors. However, the underlying mechanism of CASC19 in pancreatic cancer (PC) was still unknown. The purpose of this study was to explore the biological and clinical significance of CASC19 in PC. PATIENTS AND METHODS RT-qPCR assay was adopted to analyze CASC19 expression in PC tissues and cell lines. Furthermore, the correlation between the CASC19 level and the survival rate of PC patients was assessed by Kaplan-Meier analysis. Bioinformatics analysis and Luciferase reporter assay were utilized to confirm the interaction between miR-148b and CASC19 or E2F7. Cell viability, migration, invasion, and apoptosis were analyzed using MTT, transwell, and TUNEL assays. RESULTS The results elucidated that CASC19 expression was markedly increased in PC tissues and cell lines. Patients with high expression of CASC19 had a short survival time. Silencing of CASC19 attenuated PC cell proliferation, migration, and invasion. Moreover, we identified that miR-148b was a target of CASC19. CASC19 was negatively correlated with miR-148b and positively correlated with E2F7. The inhibitory effect of CASC19 knockdown on the progression of PC was reversed by the down-regulation of miR-148b or up-regulation of E2F7. CONCLUSIONS These results demonstrated that CASC19 participated in the development of PC. The CASC19/miR-148b/E2F7 axis might be a new study direction for PC treatment.

Abstract
Machine learning (ML) has been well applied to studying equilibrium phase transition models by accurately predicating critical thresholds and some critical exponents. Difficulty will be raised, however, for integrating ML into nonequilibrium phase transitions. The extra dimension in a given nonequilibrium system, namely time, can greatly slow down the procedure toward the steady state. In this paper we find that by using some simple techniques of ML, non-steady-state configurations of directed percolation (DP) suffice to capture its essential critical behaviors in both (1+1) and (2+1) dimensions. With the supervised learning method, the framework of our binary classification neural networks can identify the phase transition threshold, as well as the spatial and temporal correlation exponents. The characteristic time t_{c}, specifying the transition from active phases to absorbing ones, is also a major product of the learning. Moreover, we employ the convolutional autoencoder, an unsupervised learning technique, to extract dimensionality reduction representations and cluster configurations of (1+1) bond DP. It is quite appealing that such a method can yield a reasonable estimation of the critical point.

Abstract
Objective: To discuss the new idea of on-the-spot recompression treatment and multidisciplinary treatment (MDT) for patients with unstable vital signs of type II decompression sickness. To provide reference for the nearby treatment of patients with critical decompression sickness. Methods: The clinical data of a case of a multi-disciplinary collaborative treatment of type II decompression sickness complicated with multiple organ dysfunction syndrome (MODS) admitted to a third-class A hospital in January 2020 were analyzed and summarized. Results: The patient suffered from consciousness disturbance and shock after 3 min of diver's blow-up out of the water. CT examination showed gas accumulation in the systemic multi-organ venous system, and laboratory examination suggested MODS. The oxygen inhalation regimen was given in the session of recompression treatmen by 0.12-0.18 MPa. Intravenous fluid was the total of 8900 ml in the session, and the total recompression treatment time was 9 h 45 min. The patient was still in unconscious when he finished the session. CT re-examination confirmed the elimination of venous bubbles, and laboratory examination indicated multiple organ failure (MOF) . The patient was given comprehensive supporting treatment by mechanical assisted breathing and following by continuons renal replacement therapy (CRRT) and extrocorporeal membrane oxygenation (ECMO) in the intensive care unit, and was discharged after 32 d of hospitalization. Conclusion: Critical decompression sickness patients with unstable vital signs are taken to a local general hospital with hyperbaric oxygen chamber and intensive care unit. The successful treatment can be achieved by organizing diving medicine, hyperbaric oxygen medicine and critical medical personnel for MDT.

Abstract
Considering the insufficient understanding of pulmonary cryptococcosis (PC) with consolidation, 22 patients were evaluated based on the chest computed tomography (CT) images and clinical manifestation. The clinical symptoms were mild, mainly manifesting as cough and sputum. Pulmonary lesions mostly involved a single lobe in a single lung with multiple lesions. Specifically, single lung involvement was observed in 17 cases, single lobe in 16 cases and multiple lesions in 14 case. Fifteen cases were mainly distributed in the periphery and 17 cases in the long axis in parallel to the pleura. Nineteen cases had air bronchograms. Eight cases displayed cavitation inside the lesions and 18 cases had surrounding halo signs. Seventeen cases had pleural thickening, of which 10 cases had "pasting wall" signs. The clinical symptoms of PC with consolidation were relatively mild. Comprehensive clinical and imaging performance could improve the diagnosis of the disease.

Abstract
AIMS To develop an essential oil (EO)-loaded textile coating using an environmentally friendly microemulsion technique to achieve both antimicrobial and mosquito repellent functionalities. METHODS AND RESULTS Minimum inhibitory concentrations and fractional inhibitory concentrations of litsea, lemon and rosemary EOs were determined against Staphylococcus aureus, Escherichia coli, Staphylococcus epidermidis, Pseudomonas aeruginosa and Trichophyton rubrum. A 1 : 2 mixture of litsea and lemon EOs inhibited all the microorganisms tested and was incorporated into a chitosan-sodium alginate assembly by a microemulsification process. The EO-loaded microemulsions were applied to cotton and polyester fabrics using a soak-pad-dry method. The textile challenge tests demonstrated 7-8 log10 reductions of S. epidermidis, S. aureus and E. coli after 24 h and T. rubrum after 48 h. Aedes aegypti mosquito repellency was also assessed which demonstrated 71·43% repellency compared to 52·94% by neat EO-impregnated cotton. CONCLUSIONS Textiles treated with the litsea and lemon EO microemulsion showed strong antimicrobial activity against the skin associated microorganisms E. coli, S. aureus, S. epidermidis and T. rubrum and potential mosquito repellent properties. SIGNIFICANCE AND IMPACT OF THE STUDY EOs could be useful for the development of natural, environmentally friendly functional textiles to protect textiles and users from microbial contamination in addition to possessing other beneficial properties such as mosquito repellency.

Abstract
STUDY DESIGN Retrospective analysis. OBJECTIVE To define C2-C3 vertebral disc angle (VDA) in patients with and without cervical spondylotic myelopathy. SUMMARY OF BACKGROUND DATA C2-C3 VDA is a new radiological index of cervical spine alignment. Recent studies have suggested that high postoperative values are associated with greater mechanical complications in patients with cervical spondylotic myelopathy. However, normative values for patients without myelopathy has yet to be defined. METHODS Patients with and without cervical myelopathy between 2017 and 2019 were included. Inclusion criteria were patients above 18 years of age with antero-posterior (AP) and lateral (LAT) cervical X-rays. In the non-myelopathic group, patients were excluded if they had neurological symptoms or deficits, presence of cervical axial pain, previous spinal surgery, or diagnosis of either spondylolisthesis or scoliosis. In the myelopathic group, patients were excluded if they had previous spinal surgery. Radiological indices evaluated include: C2-C3 disc angle, C2-C7 Cobb angle, C7 sagittal vertical axis, T1 slope. RESULTS In total, 99 patients without myelopathy and 22 patients with myelopathy were identified and analyzed. In patients without myelopathy, the mean for C2-C3 VDA was 25.9±7.9. For patients with myelopathy, preoperative values were 24.4±10.0 and 27.1±7.9 postoperatively. No statistically significant differences were found between patients with and without myelopathy. C2-C3 disc angle was not correlated with age (R=-0.173). CONCLUSION This study did not find statistically significant differences in C2-C3 VDA values between patients with and without cervical myelopathy. This study provides normative data for C2-C3 vertebral disc angle in patients with and without cervical spondylotic myelopathy. Furthermore, C2-C3 vertebral disc angle may be independent from age.

Abstract
Objective: To investigate the effect of heat shock protein 60 (HSP60) overexpression on the ability of bone marrow mesenchymal stem cells (MSCs) and its therapeutic effect on rats with phosgene induced acute lung injury. Methods: HSP60 was transfected into MSCs by adenovirus. Western blot was used to measure the expressions of HSP60 before and after transfection. CCK-8 assay was used to detect the activity of MSCs, flow cytometry was used to detect the apoptotic ability of MSCs, and Transwell assay was used to observe the migration ability of MSCs. Sixty SPF grade male SD rats were randomly divided into control group, phosgene exposure group (inhalation of phosgene for 5 min) , MSCs group (phosgene exposure, MSCs treatment group) and transfected MSCs group (phosgene exposure, overexpression of HSP60 MSCs treatment group) . The pathological changes of lung were observed by lung pathological section, lung wet dry ratio, the degree of pulmonary edema, the total cell count and total protein content of alveolar lavage fluid, the inflammatory changes of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in BALF and serum were observed. The data were analyzed by Graphpad Prism 8.0 software. Paired comparisons were performed by non paired t-test. One way ANOVA was used for comparison between groups. Results: The proliferation ability of MSCs transfected with HSP60[A= (0.69±0.05) ] was significantly higher than that of MSCs not transfected with HSP60[A= (0.27±0.02) ] (P<0.05) . Compared with the phosgene exposure group, the pulmonary edema and inflammatory factor infiltration of MSCs group and MSCs transfected group were reduced. However, compared with MSCs group, the degree of pulmonary edema in MSCs transfected group was significantly improved, the levels of inflammatory factors IL-6 and TNF-α were significantly decreased, and the total protein content and total cell count in bronchoalveolar lavage fluid were less (P<0.05) . Conclusion: MSCs transfected with HSP60 can enhance the ability of proliferation, anti apoptosis, migration and the curative effect in rats with phosgene induced acute lung injury.

Abstract
AIM To evaluate the lung function of coronavirus disease 2019 (COVID-19) patients using oxygen-enhanced (OE) ultrashort echo time (UTE) MRI. MATERIALS AND METHODS Forty-nine patients with COVID-19 were included in the study. The OE-MRI was based on a respiratory-gated three-dimensional (3D) radial UTE sequence. For each patient, the percent signal enhancement (PSE) map was calculated using the expression PSE = (S100% – S21%)/S21%, where S21% and S100% are signals acquired during room air and 100% oxygen inhalation, respectively. Agreement of lesion detectability between UTE-MRI and computed tomography (CT) was performed using the kappa test. The Mann–Whitney U-test was used to evaluate the difference in the mean PSE between mild-type COVID-19 and common-type COVID-19. Spearman's test was used to assess the relationship between lesion mean PSE and lesion size. Furthermore, the Mann–Whitney U-test was used to evaluate the difference in region of interest (ROI) mean PSE between normal pulmonary parenchyma and lesions. The Kruskal–Wallis test was applied to test the difference in the mean PSE between different lesion types. RESULTS CT and UTE-MRI reached good agreement in lesion detectability. Ventilation measures in mild-type patients (5.3 ± 5.5%) were significantly different from those in common-type patients (3 ± 3.9%). Besides, there was no significant correlation between lesion mean PSE and lesion size. The mean PSE of COVID-19 lesions (3.2 ± 4.9%) was significantly lower than that of the pulmonary parenchyma (5.4 ± 3.9%). No significant difference was found among different lesion types. CONCLUSION OE-UTE-MRI could serve as a promising method for the assessment of lung function or treatment management of COVID-19 patients.

Abstract
OBJECTIVES This study systematically reviewed evidence from interventions on the effect of front-of-package (FOP) nutrition labeling on food purchases. STUDY DESIGN The study design used in this study is a systematic review. METHODS Keyword search was performed in PubMed, Web of Science, Scopus, and Cochrane Library. RESULTS Fifteen studies (10 randomized controlled trials, four pre-post studies, and one case-control study) met the eligibility criteria and were included in the review. Five studies were conducted in a controlled setting through the establishment of an online virtual supermarket or physical laboratory food store solely for the intervention. In contrast, the remaining ten studies were conducted in a naturalistic setting where people commonly purchase foods (e.g., supermarket, grocery store, school/hospital cafeteria, or vending machine). FOP labels assessed included traffic lights, health star rating, daily intake guides, health warnings, and high sugar symbol labels. Compared with the control, FOP labels were effective for helping participants make healthier food purchase decisions in five of the 12 studies that assessed traffic lights labels, in one of the two studies that assessed health warning labels, and in one study that assessed high sugar symbol labels. Three assessed health star ratings and one assessed daily intake guide labels, but none revealed an effect on food purchases compared with the control. CONCLUSIONS Findings on the effectiveness of FOP nutrition labels in 'nudging' consumers toward healthier food purchases remain mixed and inconclusive. Future studies should examine other types of FOP labels beside the traffic lights labels and explore the different effects by consumer affordability, population subgroup, and shopping environment.

Abstract
Objective: To investigate the relationship between human papillomavirus (HPV) integration and prognosis of cervical cancer patients. Methods: The data of 82 patients with cervical cancer treated in the Radiotherapy Department of Peking Union Medical College Hospital from October 2004 to June 2012 were retrospectively analyzed.The patients were divided into poor prognosis group (recurrence or metastasis after surgery and adjuvant radiotherapy) and good prognosis group based on a propensity score matching strategy.The HPV integration of the two groups were detected by whole exome sequencing to determine whether the integration sites were located in the common fragile sites (CFSs). HPV integration and integration into CFSs were compared between the two groups. Results: Among the enrolled 82 patients, 37 were divided in poor survival group and 45 in good survival group. A total of 90 integration breakpoints were identified, 30 of them occurred in poor prognosis group and 60 occurred in good prognosis group. In the poor prognosis group, HPV integration occurred in 20 patients, 13 of them were inserted in CFSs of 11 patients, and the numbers in good prognosis group were 26, 17, 11, respectively. There were no significantly statistical differences in the number of HPV integration events (P=0.289), HPV integration patients (P=0.735), CFSs integration events (P=0.427), and CFSs integration patients (P=0.591) between the two groups. In poor prognosis group, more CFSs integration events occurred in patients with metastasis than those in patients with only local recurrence (9 vs 2, P=0.003). Conclusions: No significant differences are observed in HPV integration and HPV integration into CFSs between cervical cancer patients with different prognoses. HPV integration into CFSs may be associated with distant metastasis.

Abstract
Objectives: To understand the association between obesity and the risk for colorectal advanced adenoma. Methods: Community residents aged 45 to 74 who had participated in the Shanghai community-based colorectal cancer (CRC) screening project in 2008 were included in our study. Anthropometries information including body weight, height and risk factors for colorectal advanced adenoma were collected. Results on colonoscopic diagnosis and personal health records were used for supplementary outcome information retrieval. Multivariate Cox proportional hazard regression models were used to evaluate the hazard ratio (HR) and 95%CI of obesity on the risk for colorectal advanced adenoma. Results: 20 811 residents were followed up for 122 739.36 person-years, with a median follow-up time of 5.87 years. A total of 657 cases of advanced adenomas were identified. After adjusting for potential confounding risk factors such as age, sex, family history of CRC, level of education, marriage, cigarette smoking, alcohol drinking, foods intake including fat, fried or pickled, vegetables and fruits etc., the HR was 1.25 (95%CI: 1.04-1.51) for obese people when compared with the normal weight persons. Further stratified analysis by age, gender and family history of CRC, results showed that obese people had a much higher risk of colorectal advanced adenoma than those with normal weight (male: HR=1.57, 95%CI: 1.20-2.04; more than 60- year-old: HR=1.63, 95%CI: 1.23-2.16). Conclusion: Data from this large scale population-based study revealed that obesity might be an independent risk factor for colorectal advanced adenoma and the risk increases along with the increase of BMI in China.

Abstract
Antisense oligodeoxynucleotide (ASODN) can directly interfere a series of biological events of the target RNA derived from tumor cells through Watson-Crick base pairing, in turn, plays antitumor therapeutic roles. In the study, a novel HIF-1α ASODN-loaded nanocomposite was formulated to efficiently deliver gene to the target RNA. The physicochemical properties of nanocomposite were characterized using TEM, FTIR, DLS and zeta potentials. The mean diameter of resulting GEL-DGL-FA-ASODN-DCA nanocomposite was about 170-192 nm, and according to the agarose gel retardation assay, the loading amount of ASODN accounted for 166.7 mg/g. The results of cellular uptake showed that the nanocomposite could specifically target to HepG2 and Hela cells. The cytotoxicity assay demonstrated that the toxicity of vectors was greatly reduced by using DCA to reversibly block the cationic DGL. The subcellular distribution images clearly displayed the lysosomal escape ability of the DCA-modified nanocomposite. In vitro exploration of molecular mechanism indicated that the nanocomposite could inhibit mRNA expression and HIF-1α protein translation at different levels. In vivo optical images and quantitative assay testified that the formulation accumulated preferentially in the tumor tissue. In vivo antitumor efficacy research confirmed that this nanocomposite had significant antitumor activity and the tumor inhibitory rate was 77.99%. These results manifested that the GEL-DGL-FA-ASODN-DCA nanocomposite was promising in gene therapeutics for antitumor by interacting directly with target RNA.

Abstract
BACKGROUND Pemphigus vulgaris (PV) is a potentially life-threatening autoimmune bullous disease affecting the skin and mucous membranes. Its pathogenic mechanism is still not fully understood. Regulatory T cells (Tregs) have been reported to play a significant role in regulating immune homeostasis in autoimmune disorders, such as PV. AIM To investigate the potential role of Tregs in the immunopathogenesis of PV. METHODS We enrolled 15 patients with PV and 15 healthy controls (HCs). Peripheral blood samples were collected from all participants before treatment. This was followed by flow cytometric, real-time reverse transcription PCR, and in vitro inhibition-based functional assays to explore the immunopathogenesis of Tregs in PV. RESULTS Our results showed no statistically significant differences in total CD4+CD25+ cells and CD4+CD25high cells. In addition, expression levels of FOXP3 mRNA and the corresponding FOXP3 protein remained unchanged in the patients with PV and the HCs. However, the in vitro suppressive activity of CD4+CD25+ T cells was impaired in patients with PV compared with HCs. CONCLUSIONS Our observations suggest that inhibition of suppressive activity of Treg cells may be involved in the pathogenesis of PV.

Abstract
OBJECTIVE To investigate the effect and mechanism of long non-coding ribonucleic acid (lncRNA) PFL on myocardial ischemia/reperfusion (I/R) injury in rats, and to provide a reference for the prevention and treatment of myocardial infarction (MI) in clinic. MATERIALS AND METHODS According to the random number table, 60 male Sprague-Dawley (SD) rats were randomly divided into 3 groups: Control group (n=20), I/R group (n=20), and I/R + PFL small interfering ribonucleic acid (siRNA) group (n=20). The I/R model was established by ligating the left anterior descending coronary artery (LAD) and then recanalizing it. PFL siRNAs were injected intravenously into the tail vein of rats in I/R + PFL siRNA group to construct a PFL knockout model. Triphenyl tetrazolium chloride (TTC) test was used to detect the infarction area of each group. Echocardiography was adopted to measure the ejection fraction [EF (%)] and fraction shortening [FS (%)] of rats in each group. Hematoxylin and eosin (H&E) staining was applied to detect the morphological changes in myocardial cells in each group. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining was conducted to detect the apoptosis levels of myocardial cells and fibroblasts in heart tissues in each group. Meanwhile, the protein expression levels of apoptosis-related genes, Bcl-2-associated X protein (BAX), and Bcl-2, were measured via Western blotting. Also, the expression level of heat shock protein 20 (HSP-20) in the heart of three groups of rats was examined using immunohistochemical staining. Finally, the effects of PFL siRNAs on the expression level of HSP-20 were detected via Western blotting. RESULTS PFL siRNAs could significantly improve I/R-induced cardiac insufficiency in rats, thus increasing EF (%) and FS (%) (p<0.05). Besides, PFL siRNAs could remarkably inhibit cardiac infarction caused by I/R injury and reduce the infarction area from (59.54±3.45)% to (24.85±1.30)% (p<0.05). H&E staining results manifested that, compared with those in I/R group, the cardiac myofilament was better in alignment, degradation and necrosis were milder, and cell edema was notably reduced in I/R + PFL siRNA group. Immunohistochemistry and Western blotting results showed that PFL siRNAs could remarkably reverse the decrease in the HSP-20 expression caused by I/R (p<0.05). CONCLUSIONS We found that PFL knockdown can significantly improve the myocardial injury caused by I/R and improve the cardiac function in rats. The mechanism may be related to the activation of HSP-20 by PFL siRNAs. Therefore, PFL is expected to become a new target for the treatment of MI.

Abstract
Data on occupational radiation exposure of radiation workers at a tertiary hospital in China during 2013-18 were analyzed to provide decision-making advice for hospitals and health administrative departments. A total of 1255 exposure records of radiation workers were collected. The average annual effective doses of radiation workers during 2013-18 was 0.4977 mSv, with 1150 (91.63%) records ranging between 0 and 1 mSv, 91 (7.25%) between 1 and 2 mSv, 10 (0.80%) between 2 and 5 mSv and 4 (0.32%) records exceeding 5 mSv. There was a significant difference in the average annual effective dose of radiation workers among different occupational categories except in 2015 indicating that hospitals and administrative authorities should pay more attention to the radiation workers in the nuclear medicine and intervention department. The average annual effective doses did not show significant differences between male and female workers except in 2017; in that year the average individual dose of female workers was higher than male workers'. There were no significant differences in the average annual effective doses among doctors, nurses and radiologic technologists except in 2016 and 2017; during that period the individual dose of nurses was higher than doctors' and radiologic technologists'.

Abstract
Different from classical surgical anatomy which only pays attention to the morphology and structure of human organs, modern membrane anatomy focuses on not only the relationship between morphology and structure, but also the biological behavior characteristics of tumors. Membrane antomy is a theoretical system with interpretation on both the structural and disease function, so it has been accepted by more and more gastrointestinal surgeons. However, the theoretical system of gastric membrane anatomy is not mature yet. The stomach and its mesentery have undergone complex rotation and fusion in the process of embryonic development, so that surgeons have different understandings of the gastric membrane anatomy. Therefore, it is easy to cause various confusion and misunderstanding, resulting in deviations between the theory of membrane anatomy and the practice of surgery. In the present study, the mesentery of the stomach is divided into different regions, and the embryonic development process is traced back. The application and compromise encountered in the radical gastrectomy of gastric cancer will be expounded according to the membrane anatomy theory combined with the author's experience of operation.

Abstract
OBJECTIVE Breast cancer (BC) is one of the most ordinary fatal cancers. Recent studies have identified the vital role of long noncoding RNAs (lncRNAs) in the development and progression of BC. In this research, lncRNA SNHG14 was studied to identify how it functioned in the development and metastasis of BC. PATIENTS AND METHODS SNHG14 expression of tissues was detected by Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) in 50 paired patients with BC. And cell proliferation assay, colony formation assay, and transwell assay were enrolled to observe the biological behavior changes of BC cells through gain or loss of SNHG14. In addition, luciferase assays and RNA immunoprecipitation assay (RIP) were performed to discover the potential targets of SNHG14 in BC cells. RESULTS SNHG14 expression level of BC samples was higher than that of adjacent ones. Besides, cell growth ability and cell invaded ability of BC cells were inhibited after SNHG14 was silenced, while cell growth ability and cell invaded ability of BC cells were promoted after SNHG14 was overexpressed. In addition, miR-193a-3p was upregulated after silence of SNHG14 in BC cells, while miR-193a-3p was downregulated after overexpression of SNHG14 in BC cells. Furthermore, luciferase assays and RNA immunoprecipitation assay (RIP) showed that miR-193a-3p was a direct target of SNHG14 in BC. CONCLUSIONS Our study uncovers a new oncogene in BC and suggests that SNHG14 could enhance BC cell proliferation and invasion via sponging miR-193a-3p, which provided a novel therapeutic target for BC patients.

Abstract
The glacial phase, with an apparently glassy structure, can be formed by a first-order transition in some molecular-glass-forming supercooled liquids. Here we report the formation of metallic glacial glass (MGG) from the precursor of a rare-earth-element-based metallic glass via the first-order phase transition in its supercooled liquid. The excellent glass-forming ability of the precursor ensures the MGG to be successfully fabricated into bulk samples (with a minimal critical diameter exceeding 3 mm). Distinct enthalpy, structure, and property changes are detected between MGG and metallic glass, and the reversed "melting-like" transition from the glacial phase to the supercooled liquid is observed in fast differential scanning calorimetry. The kinetics of MGG formation is reflected by a continuous heating transformation diagram, with the phase transition pathways measured at different heating rates taken into account. The finding supports the scenario of liquid-liquid transition in metallic-glass-forming liquids.

Abstract
INTRODUCTION The purpose of this study was to conduct a retrospective study about the clinical effects of endoscopic mucosal dissection on the treatment of early esophagogastric precancerous lesions. METHODS A total of 132 patients with early esophagogastric precancerous lesions who were diagnosed and treated with concurrent surgery in our hospital from January 2018 to December 2019 were included in this retrospective study. Patients were divided into endoscopic mucosal resection (EMR) group (n = 58) and endoscopic submucosal dissection (ESD) group (n = 74) according to different surgical methods. The data in the two groups were compared and analyzed in terms of surgical indicators, treatment status and incidence of postoperative complications. RESULTS There were statistically significant differences between the two groups in the whole block cutting rate, fractional cutting rate and complete cutting rate (P < 0.05). The mean operation time of ESD group was significantly longer than that of EMR group (P < 0.05). There were no significant differences in the intraoperative bleeding rate, blood loss, average specimen area, length of hospital stay and treatment cost between the two groups (P > 0.05). The incidence and recurrence of postoperative complications, including bleeding, perforation and stenosis in the two groups, were observed within 1 year of postoperative follow-up. The incidence of complications in ESD group was slightly higher than that in EMR group, and the local recurrence rate in ESD group was lower than that in EMR group (P > 0.05). CONCLUSION ESD is an alternative surgical treatment for patients with early esophagogastric precancerous lesions.

Abstract
PURPOSE The supply of non-iodized salt and the water improvement project have been conducted to reduce the iodine concentration in drinking water in areas with elevated water iodine. We aimed to assess the impact of water iodine concentration (WIC) on the iodine intake of pregnant women in areas with restricted iodized salt supply, and determine the cutoff values of WIC in areas with non-iodized salt supply. METHODS Overall, 534 pregnant women who attended routine antenatal outpatient visits in Zibo Maternal and Child Health Hospital in Gaoqing County were recruited. The 24-h urine iodine excretion (UIE) in 534 samples and the iodine concentration in 534 drinking water samples were estimated. Urinary iodine excretion, daily iodine intake, and daily iodine intake from drinking water (WII) were calculated. The relationship between WIC and daily iodine take was analyzed. RESULTS The median WIC, spot urine iodine concentration (UIC), and 24-h UIE were 17 (6, 226) μg/L, 145 (88, 267) μg/L, and 190 (110, 390) μg/day, respectively. A significant positive correlation was found between WIC and UIE (R2 = 0.265, p < 0.001) and UIC (R2 = 0.261, p < 0.001). The contribution rate of WII to total iodine intake increased from 3.0% in the group with WIC of < 10 μg/L to 45.7% in the group with WIC of 50-99 μg/L. CONCLUSION The iodine content in drinking water is the major iodine source in pregnant women living in high-water iodine areas where iodized salt supply is restricted. The contribution rate of daily iodine intake from drinking water increases with the increase in water iodine concentration.

Abstract
Bleeding and blood transfusion are common after scoliosis surgery. Fibrinogen is essential for blood clot formation and depletes quickly during haemorrhage. We randomly allocated 102 children 12-18 years old having surgery for idiopathic scoliosis, 51 to intra-operative fibrinogen concentrate 30 mg.kg-1 (maximum 2 g) and 51 to saline placebo. Fibrinogen reduced peri-operative blood loss by a median (95%CI) volume of 155 (5-320) ml, from a median (IQR [range]) of 1035 (818-1420 [400-3030]) ml to 885 (755-1155 [270-2645]) ml, p = 0.04. Seven and four children received allogeneic red blood cell transfusion after fibrinogen and placebo, respectively, p = 0.34. There were no side-effects.

Abstract
MicroRNAs (miRNAs) are small noncoding RNAs stretching over 18-22 nucleotides and considered to be modifiers of many respiratory diseases. They are highly evolutionary conserved and have been implicated in several biological processes, including cell proliferation, apoptosis, differentiation, among others. Acute lung injury (ALI) is a fatal disease commonly caused by direct or indirect injury factors and has a high mortality rate in intensive care unit. Changes in expression of several types of miRNAs have been reported in patients with ALI. Some miRNAs suppress cellular injury and accelerate the recovery of ALI by targeting specific molecules and decreasing excessive immune response. For this reason, miRNAs are proposed as potential biomarkers for ALI and as therapeutic targets for this disease. This review summarizes current evidence supporting the role of miRNAs in ALI.

Abstract
Background:BMS-986165 is an oral, selective inhibitor of tyrosine kinase 2 (TYK2) with a unique mode of binding to the pseudokinase domain of the enzyme rather than the active site within the kinase domain. This unique mode of binding provides high functional selectivity for TYK2 versus other tyrosine kinases (TYKs) in cellular and other in vitro assays.1This approach may provide robust efficacy with a differentiated safety profile due to decreased off-target activity on other kinases. In a 12-week, placebo-controlled Phase 2 trial in patients with moderate to severe plaque psoriasis,2BMS-986165 had a favorable safety profile, and 67%–75% of patients achieved Psoriasis Area and Severity Index 75 (PASI 75) after 12 weeks at doses ≥3 mg twice daily versus 7% with placebo. BMS-986165 is currently under investigation in multiple autoimmune disorders such as psoriatic arthritis, psoriasis, and systemic lupus erythematosus.Objectives:To understand the selectivity of BMS-986165 compared with JAK inhibitors, such as tofacitinib (Tofa), upadacitinib (Upa), and baricitinib (Bari), at clinically relevant doses and plasma concentrations.Methods:In vitro whole blood assays were developed to measure the activity of common pairings of JAKs (JAK 1/3, JAK2/2, and TYK2/JAK2) and concentrations providing half-maximal inhibition (IC50) for BMS-986165, Tofa, Upa, and Bari were determined. The whole blood IC50values were plotted against pharmacokinetic profiles of these agents at approved doses and/or doses evaluated in their respective Phase 2/3 trials. The time that concentrations were >IC50and projected average daily inhibition were evaluated.Results:At clinically relevant doses and exposures, BMS-986165 plasma concentrations were higher than the TYK2 whole blood IC50value for a considerable part of the dosing interval. Additionally, the maximal plasma concentration (Cmax) of BMS-986165 was approximately >9- to 18-fold lower than the JAK 1/3 whole blood IC50value and >52- to >109-fold lower than JAK2/2 whole blood IC50, indicating lack of meaningful inhibition of the JAK 1-3 pathways by BMS-986165 at therapeutic doses. At clinically relevant doses, projected Cmaxvalues of Tofa, Upa, and Bari were many-fold lower than TYK2 IC50, indicating minimal or no meaningful inhibition of the TYK2 pathway. As expected, Tofa, Upa, and Bari had varying degrees of inhibition against JAK1/3 (daily average inhibition range: 70%–94%) and JAK2/2 pathways (daily average inhibition range: 24%–67%) at clinically relevant doses and exposures.Conclusion:These results demonstrate the high TYK2 functional selectivity of BMS-986165 at clinically relevant doses and plasma concentrations compared with Tofa, Upa, and Bari and indicate that BMS-986165 is in a different class compared with JAK 1–3 inhibitors. Ongoing studies in psoriasis and other conditions may confirm the expected safety of BMS-986165 based on the above results. The daily average inhibition of JAK1 and JAK2 likely explains some common laboratory observations and adverse events reported for the JAK1–3 inhibitors.References:[1]Burke JR et al.Sci Transl Med. 2019 Jul 24;11(502); eaaw1736.[2]Papp K et al.N Engl J Med. 2018;379(14):1313-1321.Acknowledgments:This study was sponsored by Bristol-Myers Squibb.

Abstract
To investigate the characteristics of diffusion tensor imaging (DTI) of the central nervous system in children with Tourette syndrome (TS).Fifteen children with TS (TS group) and 15 normal children (control group) were studied, and all of them underwent DTI. The apparent diffusion coefficient (ADC) and fractional anisotropy (FA) parameters were calculated using the DTIStudio software. The region of interest was delineated manually. The ADC and FA values of the bilateral caudate nucleus, bilateral globus pallidus, bilateral putamen, bilateral thalamus, and bilateral frontal lobe white matter were measured using the region of interest editor software. The differences of FA values and ADC values between the same brain areas were compared. The associations between ADC, FA values and Yale Global Tic Severity Scale (YGTSS) scores were evaluated by Pearson correlation analyses.The FA values of left globus pallidus and left thalamus were significantly lower in the TS group than in the control group (P < .05), while the ADC values of the right caudate nucleus and bilateral thalamus were significantly higher in the TS group than in the control group (P < .05). The decrease in FA in the left thalamus significantly correlated with the YGTSS score (r = 0.692; P < .05). No correlation was found between FA and ADC values in other brain regions and the YGTSS score (P > .05).After the DTI analyses, abnormalities were found in the left globus pallidus, right caudate nucleus, and bilateral thalamus in children with TS. Especially the changes in the left thalamus structure was crucial in the pathophysiological clock of TS.

Potential effects of IL-17A rs2275913 and IL-17F rs763780 polymorphisms on susceptibility to gastric cancer in Chinese population: a meta-analysis. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2020; 24:3633-3641. [PMID: 32329838 DOI: 10.26355/eurrev_202004_20825] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Indexed: 11/12/2022]
Abstract
OBJECTIVE This meta-analysis aims to clarify the effect of IL-17 polymorphisms on the susceptibility to GCa in the Chinese population. MATERIALS AND METHODS Relevant pieces of literature were searched in PubMed, Web of School, VIP, and CNKI using the key words as "IL-17, gastric/stomach cancer" or "IL-17 polymorphisms, gastric/stomach cancer susceptibility". The odds ratio (OR) and 95% confidence interval (CI) in the selected studies were calculated using RevMan5.3 and STATA12.0. RESULTS A total of 12 investigations reporting mutations in IL-17A rs2275913 and IL-17F rs763780 were enrolled. There were 11 studies reporting rs2275913 G>A, involving 3299 cases of GCa patients and 3339 cases of healthy controls. The random-effects model was performed since the heterogeneity test results of the recessive genetic model (GG&GA vs. AA) and the allelic model (G vs. A) of IL-17A rs2275913 G>A were I2>66%/p=0.001. Meanwhile, the dominant genetic model (GG vs. GA&AA) and the super-dominant genetic model (GA vs. GG&AA) of IL-17A rs2275913 G>A were I2< 50%/p>0.05, and the fixed-effects model was used. The meta-analysis showed that IL-17A rs2275913 G>A was positively correlated with GCa susceptibility under four genetic models (p<0.05). Five studies reporting IL-17F rs763780 T>C were enrolled, including 2535 cases of GCa patients and 2402 cases of healthy controls. The heterogeneity test showed that, except for the super-dominant genetic model, the p-value was <0.00001 in the dominant, recessive, and allelic models, and their I2 values were 87%, 88%, and 93%, respectively. Hence, a random-effects model was selected. IL-17F rs763780 T>C was positively correlated with GCa susceptibility under the super-dominant genetic model (p=0.003), rather than the other three models (p>0.05). CONCLUSIONS IL-17A rs2275913 G>A polymorphism contributes to susceptibility to GCa in the dominant, recessive, allelic, and super-dominant models. Meanwhile, IL-17F rs763780 T>C polymorphism is positively correlated with GCa susceptibility in the super-dominant model.

Feasibility of using dynamic contrast-enhanced MRI for differentiating thymic carcinoma from thymic lymphoma based on semi-quantitative and quantitative models. Clin Radiol 2020; 75:560.e19-560.e25. [PMID: 32197918 DOI: 10.1016/j.crad.2020.02.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2019] [Accepted: 02/18/2020] [Indexed: 01/02/2023]
Abstract
AIM To evaluate the value of using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) derived parameters to differentiate thymic carcinoma and thymic lymphoma based on semi-quantitative and quantitative models. MATERIALS AND METHODS Twenty-nine pathologically confirmed anterior mediastinum tumours in 29 patients were enrolled in this retrospective study, including 15 thymic carcinoma and 14 lymphoma patients. All the patients underwent pre-treatment mediastinum DCE-MRI. Both semi-quantitative and quantitative parameters were calculated and the volume transfer constant Ktrans, the flux rate constant between extravascular extracellular space and plasma kep, the extravascular extracellular volume fraction ve were obtained based on a modified Tofts model. DCE-MRI derived parameters were compared between thymic carcinoma and thymic lymphoma groups. RESULTS Thymic carcinoma had significantly lower kep (p=0.040) and higher ve (p=0.018) than thymic lymphoma; however, there were no significant differences on Ktrans and semi-quantitative parameters between the two groups. ve had the highest area under the curve (cut-off value, 0.282; area under the curve, 0.748; sensitivity, 71.4%; specificity, 80%). The combination of kep and ve could increase the diagnostic performance significantly (area under the curve, 0.752; sensitivity, 57.1%; specificity, 93.3%). CONCLUSION DCE-MRI derived parameters may have value in the differentiating thymic carcinoma and thymic lymphoma.
