Abstract
Objective: To evaluate the characteristics of adult abdominal fat distribution and analyze its influencing factors by energy spectrum CT scan. Methods: The body height, weight, waist circumference, and hip circumference of 105 adults were measured, and the characteristics of abdominal fat distribution were evaluated by energy spectrum CT scan. Results: Compared with non-obese individuals, the contents of abdominal subcutaneous fat, abdominal cavity and liver ectopic fat were higher in obese patients (P<0.05), and the intramuscular fat (IMAT) content did not increase with the increase of BMI. In middle-aged group, the waist circumference, waist-to-hip ratio (WHR) abdominal cavity area and IMAT content were higher than those in the youth group, and the muscle content of the middle-aged group was lower than that of the youth group, the difference between the two groups was significant (P<0.05); the male group had higher abdominal cavity area and muscle content than the female group, while the female group had higher the subcutaneous fat area, abdominal subcutaneous fat thickness and erector spinae fat content than the male group, the differences were significant (P<0.05). Conclusions: The characteristics of abdominal fat distribution of subjects with different BMI, age and gender were different. Therefore, we should pay attention to the individual assessment of ectopic fat distribution in obese patients. Energy spectrum CT can be used as an important approach for the assessment of ectopic fat to provide evidence for developing individualized weight loss programs.

Abstract
Objective: To analyze the gender difference in secular trends of body height in Chinese Han adolescents aged 18 years from 1985 to 2014. Methods: Data were extracted from 1985, 1995, 2000, 2005, 2010 and 2014 Chinese National Surveys in Students' Constitution and Health. A total of 124 099 Chinese Han adolescents aged 18 years were included in the analysis. ANOVA test was used to compare the body height between different subgroups stratified by gender and the mean difference and ratio in body height were calculated. Quantile regression model was used to assess the association between body height and gender over time in the adolescents stratified by region or area. Results: The mean body height of adolescents aged 18 years increased significantly from 1985 to 2014 with the rate of 1.3 cm/decade in male adolescents and 0.8 cm/decade in female adolescents, and the highest increment occurred from 1995 to 2005 in both groups. Male adolescents were taller than female adolescents at each subgroup (P<0.05). Gender difference in body height increased from 11.1 cm in 1985 to 12.6 cm in 2014 and ratio remained to be 1.07-1.08. The body height was taller in adolescents in urban area than in rural area (P<0.05) and in northeastern China than in other regions (P<0.05) in both male and female adolescents. The body height of obese male adolescents had been taller since 2000 and the body height of obese female adolescents had been taller since 2010 than other groups. When adjusted for urban-rural areas, region, socioeconomic status and nutritional status, the body height increased over time at P5, P25, P50, P75 and P95 in both male and female adolescents, and the increments of gender difference in body height at different percentile ranged from 0.45 cm/decade to 0.57 cm/decade. When stratified by region, the gender difference in body height showed similar trend with total sample except P5 and P95 in northeastern China, the difference of increments were not significant. Conclusions: From 1985 to 2014, the gender difference in body height of Chinese Han adolescents aged 18 years increased, and male adolescents showed greater increase than female adolescents. Moreover, the adolescents in northeastern and eastern China had larger increment in body height. It is necessary to paid more attention to the adolescents in central and western China to promote their physical development.

Abstract
Background Influenza-associated acute necrotizing encephalopathy (IANE) can be lethal and disabling and have a sudden onset and deteriorate rapidly but lacks early diagnostic indicators. We aimed to examine the early clinical diagnostic indicators in children with IANE. Material/Methods Acute influenza patients were grouped according to their clinical manifestations: flu alone (FA), flu with febrile seizure (FS), influenza-associated encephalopathy (IAE), and IANE. The clinical features, biomarkers, neuroelectrophysiological results, and neuroimaging examination results were compared. Results A total of 31 patients were included (FA (n=4), FS (n=8), IAE (n=14), and IANE (n=5)). The IANE group, whose mean age was 3.7 years, was more likely to show rapid-onset seizure, acute disturbance of consciousness (ADOC), Babinski’s sign, and death/sequela. More patients in the IANE group required tracheal intubation mechanical ventilation and received intravenous immunoglobulins (IVIG) and glucocorticoids. The alanine aminotransferase (ALT), aspartate transaminase (AST), and lactate dehydrogenase (LDH) levels in the IANE group were significantly higher than in the FS and IAE groups. The aquaporin-4 (AQP-4) antibody and malondialdehyde (MDA) levels in the serum and cerebrospinal fluid (CSF) were notably higher in IANE patients in the acute stage compared with FS and IAE patients. All patients in the IANE group had positive neuroimaging findings. Conclusions Early clinical warning factors for IANE include rapid-onset seizures in patients under 4 years of age, ADOC, and pathological signs. Increased AQP-4 antibodies and MDA levels in CSF might contribute to early diagnosis. Early magnetic resonance venography (MRV) and susceptibility-weighted imaging (SWI) sequences, or thrombelastography to identify deep vein thrombosis, might indicate clinical deterioration.

Abstract
Metabolic-associated fatty liver disease (MAFLD) is currently the most common chronic liver disease in the world, which may eventually progress to cirrhosis, hepatocellular carcinoma and liver failure. Fatty liver disease was once considered to be the most common cause of cryptogenic cirrhosis. Recently, a new definition of MAFLD suggests that MAFLD-related liver cirrhosis is no longer a kind of cryptogenic cirrhosis, and it belong to two different concepts and may have different liver and extrahepatic adverse outcomes. In this paper, the definition, epidemiology, diagnosis, treatment and other aspects of MALFD-related liver cirrhosis and cryptogenic liver cirrhosis are described in order to facilitate clinical practice, improve the efficiency of clinical research, and benefit clinicians and patients.

Abstract
Objective: To explore the characteristics of sleep-disordered breathing (SDB) in chronic heart failure patients waiting for heart transplantation and the changes of SDB after transplantation. Methods: From September 2018 to December 2019, 34 patients with chronic heart failure were prospectively enrolled into this study, who were hospitalized for waiting for heart transplantation in the departments of cardiovascular medicine and cardiovascular surgery, Renmin Hospital of Wuhan University. All of them received portable sleep physiological monitoring. The characteristics of their SDB were analyzed before and after heart transplantation. Results: Of the 34 patients waiting for heart transplantation, 22 had central sleep apnea, 4 had obstructive sleep apnea and 8 had no SDB. The cycle length of Cheyne-Stokes respiration was negatively correlated with left ventricular ejection fraction. After heart transplantation, 15 patients received repeat sleep physiological monitoring and their results showed that the SDB was significantly improved, with the elimination of Cheyne-Stokes respiration. Conclusions: Patients waiting for heart transplantation had a high prevalence of SDB, with Cheyne-Stokes respiration with central sleep apnea as the main type. However, heart transplantation may eliminate the Cheyne-Stokes respiration in patients with chronic heart failure.

Abstract
We propose a novel type of photonic-crystal (PC)-based nanostructures for efficient and tunable optically-induced spin current generation via the spin Seebeck and inverse spin Hall effects. It has been experimentally demonstrated that optical surface modes localized at the PC surface covered by ferromagnetic layer and materials with giant spin-orbit coupling (SOC) notably increase the efficiency of the optically-induced spin current generation, and provides its tunability by modifying the light wavelength or angle of incidence. Up to 100% of the incident light power can be transferred to heat within the SOC layer and, therefore, to the spin current. Importantly, the high efficiency becomes accessible even for ultra-thin SOC layers. Moreover, the surface patterning of the PC-based spintronic nanostructure allows for the local generation of spin currents at the pattern scales rather than the diameter of the laser beam.

Abstract
PURPOSE Gitelman syndrome (GS) is an autosomal recessive renal tubular disease that arises as a consequence of mutations in the SLC12A3 gene, which codes for an Na-Cl cotransporter (NCC) in distal renal tubules. This study was designed to explore the mutations associated with GS in an effort to more fully understand the molecular mechanisms governing GS. METHODS We analyzed SLC12A3 mutations in a pedigree including a 42-year-old male with GS as well as four related family members over three generations using Sanger and next generation sequencing approaches. We additionally explored the functional ramifications of identified mutations using both Xenopus oocytes and the HEK293T cell line. RESULTS We found that the subject with GS exhibited characteristic symptoms including sporadic thirst, fatigue, excess urination, and substantial hypokalemia and hypocalciuria, although magnesium levels were normal. Other analyzed subjects in this pedigree had normal laboratory findings and did not exhibit clear signs of GS. Sequencing analyses revealed that the GS subject exhibited a homozygous missense mutation (c.2874C > G, p.N958K) in exon 24 of SLC12A3. Both parents of this GS subject, as well as his older brother and daughter all exhibited heterozygous mutations at this same site. Functional analyses in Xenopus oocytes indicated that this mutated SLC12A3 gene encodes a protein which fails to mediate normal sodium transport, and when this mutant gene was expressed in HEK293T cells, we observed significant increases in endoplasmic reticulum (ER)-stress pathway activation. CONCLUSION The p.N958K mutation in exon 24 of SLC12A3 can trigger GS at least in part via enhancing ER stress responses.

Abstract
OBJECTIVE Rat intervertebral disc (IVD) is one of the most commonly used and cost-effective alternative models for human IVD. Many IVD related clinical studies need to be pre-tested on rat IVDs. However, studies on the heterogeneous cell clusters of the rat IVD are inadequate, and a further understanding of the marker genes and cell phenotypes of healthy mature IVD cells is essential. METHODS In this study, we used the 10X Genomics technology to analyze the single-cell transcriptome of purified wild-type rat IVDs. RESULTS We identified potentially new gene markers of IVDs via single-cell sequencing. Based on the unsupervised cluster analysis of 13,578 single-cell transcripts, 3 known IVD cell types were identified. We provided a complete single-cell gene expression map of the IVD. Immunohistochemical and immunofluorescence images of rat disc sections confirmed the new marker genes of all cell types. One group of heterologous cell groups expressed multi-functional stem cell (MSC)-specific genes, indicating the stem cell potential of IVD cells. CONCLUSION We provided the phenotype and marker genes of IVD cells at the single-cell level, reconfirmed existing data, and proposed new marker genes, including MSC marker genes. By identifying more accurate target cells and genes, our results pave the way for further study of the response of individual disc cells to disease states and provide the basis for future disc regeneration therapies.

Abstract
PURPOSE To evaluate the changes in ocular biomechanical properties in active moderate-to-severe Graves' orbitopathy (GO) after intravenous glucocorticoids (IVGCs), and to clarify correlations between clinical findings and ocular biomechanical properties. METHODS A prospective study. A total of 20 consecutive GO patients and 20 age- and sex-matched healthy control subjects were included. GO was diagnosed on the basis of the recommendation by the European Group on Graves' Orbitopathy (EUGOGO), and disease activity was assessed by the clinical activity score (CAS). Patients were assigned to receive once weekly IVGCs (0.5 g, then 0.25 g, 6 weeks each). All participants received a full ophthalmic examination and biomechanical evaluation was performed with dynamic Scheimpflug analyzer (Corvis ST) at baseline and 12th weeks after therapy. RESULTS The biomechanically corrected intraocular pressure (bIOP) in GO patients was significantly higher than that in healthy subjects. In contrast, the whole eye movement (WEM) in GO patients was significantly lower than in healthy subjects after adjusting for bIOP. The CAS, NOSPECS score, and exophthalmos were significantly positively correlated with the bIOP and negatively correlated with the WEM after adjusting for bIOP, CCT and age. The WEM significantly increased, whereas bIOP significantly decreased after IVGCs (P < 0.001, P = 0.001 respectively). The overall response rate at the 12th week was 85% (17 of 20). CONCLUSIONS The changes of ocular biomechanical properties measured by Corvis ST were an objective indicator of inflammatory activity and severity of GO. Combining CAS and ocular biomechanical properties could better evaluate the therapeutic outcome of active moderate-to-severe GO.

Abstract
OBJECTIVE To investigate the effect of long non-coding RNA UPK1A-AS1 on glycolysis of hepatocellular carcinoma cells and its underlying molecular mechanisms. OBJECTIVE A hepatocellular carcinoma (HCC) cell line with lentivirus-mediated stable UPK1A-AS1 overexpression and the cells infected with a negative control lentiviral vector were cultured under normoxic (21% O2) or hypoxic (1% O2) conditions for 24 h. The effect of UPK1A-AS1 overexpression on glycolysis of the HCC cells was examined. The expressions of glycolysis-related genes HIF1A, GLUT1, HK1, HK2 and PGK1 were detected by qRTPCR, and the effect of UPK1A-AS1 overexpression on HRE activity was detected by dual luciferase report assay. The HCC cells were treated with cycloheximide to detect the effect of UPK1A-AS1 overexpression on the stability of HIF-1α protein. Immunoprecipitation assay was used to analyze the changes in ubiquitin modification of HIF-1α protein in response to UPK1A-AS1 overexpression. The effects of UPK1A-AS1 overexpression and RNA interference of HIF-1α expression on glucose consumption, lactate production and expressions of HRE activity and glycolysis-related genes (HK1, HK2 and PGK1) were examined in the HCC cells. OBJECTIVE Compared with the control group, overexpression of UPK1A-AS1 significantly promoted glucose consumption and lactate production in HCC cells under both normoxic and hypoxic conditions (P < 0.05). Overexpression of UPK1A-AS1 significantly increased the expression of glycolysis-related genes including HIF1A, GLUT1, HK1, HK2 and PGK1. Upregulation of UPK1A-AS1 obviously promoted the transcriptional activity of HRE (P < 0.05). Western blotting showed that UPK1A-AS1 overexpression obviously increased the stability of HIF-1α protein and significantly reduced ubiquitin modification of HIF-1α. Downregulation of HIF-1α obviously reversed the effect of UPK1A-AS1 overexpression in promoting glucose consumption, lactate production and HRE luciferase activity. Silencing HIF-1α also suppressed the upregulation of glycolysis-related gene expressions induced by UPK1A-AS1 overexpression (P < 0.05). OBJECTIVE The long noncoding RNA UPK1A-AS1 upregulates the expression of glycolysis-related genes by stabilizing the expression of HIF-1α, thereby promoting glycolysis level in HCC cells.

Abstract
Objective: To explore the clinicopathological characteristics and prognosis of patients with ovarian metastases from colorectal cancer. Methods: A total of 122 female patients with ovarian metastases from colorectal cancer underwent treatment in Cancer Hospital, Chinese Academy of Medical Sciences between 2010 and 2015 were recruited. The clinicopathological features, treatment details and survival data of these patients were retrospectively analyzed. Kaplan-Maier method was used for survival analysis, log rank test and Cox proportional hazards model were used for prognostic factor analysis. Results: The median overall survival (OS) was 19.7 months. The 1-year, 3-years and 5-years OS rates were 72.1%, 24.7% and 9.9%, respectively. A total of 99 (81.1%) patients underwent oophorectomy. The median OS of patients who underwent oophorectomy was 21.9 months, significantly longer than 10.3 months of patients without oophorectomy (P<0.01). Ovary as the only site of metastasis, primary tumor resection, and oophorectomy were associated with improved survival (all P<0.01). Primary tumor resection and oophorectomy were independent prognostic factors for OS (both P<0.01). Conclusion: Patients with ovarian metastases from colorectal cancer might acquire a survival benefit from surgical resection of the primary tumor and ovaries.

Abstract
Objectives: To analyze the reasons of residual partial anomalous pulmonary venous connection (PAPVC) after previous cardiac surgery, and summarize the strategies and experience for diagnosis and treatment of secondary correction operation. Methods: The clinical data of 18 patients who were admitted to Fuwai Hospital of Chinese Academy of Medical Sciences and Fuwai Yunnan Cardiovascular Hospital from June 2009 to May 2019 were retrospectively analyzed. All the patients underwent secondary cardiac surgery to treat PAPVC. The preoperative and intraoperative characteristics and postoperative complications of the patients were summarized and analyzed. Results: Totally, there were 7 male and 11 female cases, aged 1-49 years (median age: 4.5 years). In the first cardiac surgery, 3 patients were diagnosed with PAPVC, which existed after surgery. One patient was diagnosed with total anomalous pulmonary venous connection (TAPVC), but left PAPVC after surgery. The remaining 14 patients were all missed preoperative and intraoperative diagnosis. After the initial surgery, most patients had no significant symptoms (11/18), but PAPVC was found in 11 cases due to postoperative cardiac murmur or transthoracic echocardiography (TTE). In the secondary surgery, there were 4 cases of type A, 10 cases of type B, 2 cases of type C, no type D, and 2 cases of mixed type, respectively, according to Bordy classification. The diagnostic accuracy of TTE and CT angiography (CTA) was 50.0% and 92.9%, respectively. There was no death after the second surgery, but pulmonary vein occlusion, pericardial effusion, anastomotic stenosis and other complications occurred in 4 patients. Conclusions: The main causes of missed diagnosis of PAPVC are the undefined cardiac structural deformities before operation and the lack of careful exploration during the operation. TTE is simple and feasible to diagnose PAPVC, and it can improve the diagnostic accuracy when combined with CTA.

Abstract
This study aimed to evaluate the causal association of periodontal disease with acute myocardial infarction (AMI) and stroke, after controlling for various confounders among the Korean population. A retrospective cohort study using the National Health Insurance Service-National Health Screening Cohort (NHIS-HEALS) was performed during 2002 to 2015 (baseline: 2002 to 2005; follow-up: 2006 to 2015) in the Republic of Korea. A total of 298,128 participants with no history of AMI or stroke were followed up for 10 y. AMI and stroke were defined by a diagnosis using the International Classification of Diseases, 10th Revision (ICD-10) guideline. Periodontal condition was classified into 3 groups (healthy, moderate periodontal disease, severe periodontal disease [SPD]) using the combination of ICD codes, treatment codes in the NHIS, and recommendation of periodontal treatment by the dentists in HEALS. Various confounders, such as sociodemographic, behavioral, systemic, and oral health factors, including hypercholesterolemia, were considered. Multivariable Cox regression analysis was applied to estimate adjusted incidence rate ratio (adjusted hazard ratio [aHR]) based on person-year of periodontal condition for AMI, stroke, and nonfatal major adverse cardiovascular events (MACEs) encompassing AMI or stroke controlling for various confounders. Stratified analyses according to age group, sex, and toothbrushing frequency were also performed. After controlling for various confounders, participants with SPD compared with non-SPD participants had a higher incidence by 11% for AMI (aHR, 1.11; 95% confidence interval [CI], 1.02-1.20), by 3.5% for stroke (aHR, 1.035; 95% CI, 1.01-1.07), and by 4.1% for MACEs (aHR, 1.04; 95% CI, 1.01-1.07). The association of SPD with AMI and MACE was highly modified in females and adults aged 40 to 59 y. In the total Korean population, SPD increased total AMI events by 4.3%, total stroke events by 1.4%, and the total MACEs by 1.6%. Our data confirmed that SPD was causally associated with the new events of AMI and stroke.

Abstract
First-principles calculations were performed to study the electrochemical performance of M2TiC2 (M = Cr or Mo) and M2TiC2Tx (T = O, F or OH) used as anode materials for sodium ion batteries (SIBs). The O functionalized MXenes (Cr2TiC2O2 and Mo2TiC2O2) are found to be more stable than F and OH terminated systems. The diffusion performance of sodium in MXene materials is mainly affected by the functional groups. The lowest diffusion barrier of functionalized MXenes is about one order larger in magnitude than that of bare MXenes. Although the introduction of O-groups hinders the diffusion of sodium, it can greatly improve the theoretical storage capacities. Meanwhile, the diffusion paths and diffusion energy barriers of Na are affected by Na concentration effects, while the interactions between terminations have little effect. Furthermore, multiple layers of sodium atoms are found to be adsorbed between the layers of M2TiC2O2, thus significantly increasing the theoretical capacities. The theoretical sodium storage capacities of M2TiC2O2 monolayers reach 515.70 mA h g-1 (M = Cr) and 362.46 mA h g-1 (M = Mo) and the OCVs can approach 0.034 V (M = Cr) and 0.042 V (M = Mo). Therefore, Cr2TiC2O2 and Mo2TiC2O2 are expected to be promising anode materials for SIBs due to their excellent properties, such as good electronic conductivity, low sodium diffusion barrier, and high theoretical sodium storage capacity.

Abstract
Objective: To analyze the etiological characteristics and molecular epidemiological correlation of five cases of typhoid fever during the same period in yantai city. Methods: Six S. Typhis strains were isolated from 5 typhoid patients and epidemiological samples in Yantai city in 2018. The onset time of the cases were from May 26, 2018 to July 24, 2018, distributed in Shuidao Town of Muping District, Dengzhou Street of Penglai District, Donglai Street of Longkou District, Wenhua Street of Muping District and Fulaishan Street of zhifu District. S. Typhis strains were analyzed by conventional bacterial isolation method and XbaⅠ/BlnⅠ double-enzyme digestion pulse-field gel electrophoresis (PFGE). Meanwhile, ViaB virulence gene detection and 27 common antibiotics sensitivity tests were conducted to study the etiology of S. Typhis. Results: Six strains of S. Typhi were isolated from 5 patients and the domestic egg of one patient, which were divided into 4 PFGE patterns by PFGE-XbaⅠ and PFGE-BlnⅠ and among which 3 strains had the same PFGE patterns.One multi-drug resistant strain (foreign patient), one single-drug resistant strain (patient with a history of provincial retention), and one completely sensitive strain were detected. The three strains of the same PFGE pattern exhibit the same drug-sensitive phenotype which were intermediate against aminoglycosides and quinolones and susceptibility against the other antibiotics.All of the strains carried the ViaB virulence factor except the strain from the foreign patient. Conclusion: Local S. Typhi is susceptibility or intermediate against antibiotics commonly used in clinic.Sporadic cases of typhoid fever and typhoid imported infections still need attention.

Abstract
Mutagenic compounds are a potent source of human disease. By inducing genetic instability, they can accelerate the evolution of human cancers or lead to the development of genetically inherited diseases. Here, we show that in addition to genetic mutations, mutagens are also a powerful source of transcription errors. These errors arise in dividing and nondividing cells alike, affect every class of transcripts inside cells, and, in certain cases, greatly exceed the number of mutations that arise in the genome. In addition, we reveal the kinetics of transcription errors in response to mutagen exposure and find that DNA repair is required to mitigate transcriptional mutagenesis after exposure. Together, these observations have far-reaching consequences for our understanding of mutagenesis in human aging and disease, and suggest that the impact of DNA damage on human physiology has been greatly underestimated.

Abstract
Background Although influenza primarily affects the respiratory system, it can cause severe neurological complications, especially in younger children, but knowledge about the early indicators of acute necrotizing encephalopathy (ANE) is limited. The main purpose of this article is to summarize the clinical characteristics, diagnosis, and treatment of neurological complications of influenza in children, and to identify factors associated with ANE. Material/Methods This was a retrospective study of children with confirmed influenza with neurological complications treated between 01/2014 and 12/2019 at Guangzhou Women and Children’s Medical Center. A receiver operating characteristics curve analysis was performed to determine the prognostic value of selected variables. Results Sixty-three children with IAE (n=33) and ANE (n=30) were included. Compared with the IAE group, the ANE group showed higher proportions of fever and acute disturbance of consciousness, higher alanine aminotransferase, higher aspartate aminotransferase, higher creatinine kinase, higher procalcitonin, higher cerebrospinal fluid (CSF) protein, and lower CSF white blood cells (all P<0.05). The areas under the curve (AUCs) for procalcitonin and CSF proteins, used to differentiate IAE and ANE, were 0.790 and 0.736, respectively. The sensitivity and specificity of PCT >4.25 ng/ml to predict ANE were 73.3% and 100.0%, respectively. The sensitivity and specificity of CSF protein >0.48 g/L to predict ANE were 76.7% and 69.7%, respectively. Thirteen (43.3%) children with ANE and none with IAE died (P<0.0001). Conclusions High levels of CSF protein and serum procalcitonin might be used as early indicators for ANE. All children admitted with neurological findings, especially during the influenza season, should be evaluated for influenza-related neurological complications.

Inter- and intra-fractional stability of rectal gas in pelvic cancer patients during MRIgRT. Med Phys 2021; 48:414-426.

Abstract
PURPOSE Due to the electron return effect (ERE) during magnetic resonance imaging guided radiotherapy (MRIgRT), rectal gas during pelvic treatments can result in hot spots of over-dosage in the rectal wall. Determining the clinical impact of this effect on rectal toxicity requires estimation of the amount and mobility (and stability) of rectal gas during treatment. We therefore investigated the amount of rectal gas and local inter- and intra-fractional changes of rectal gas in pelvic cancer patients. METHODS To estimate the volume of gas present at treatment planning, the rectal gas contents in the planning computed tomography (CT) scans of 124 bladder, 70 cervical and 2180 prostate cancer patients were calculated. To estimate inter- and intra-fractional variations in rectal gas, 174 and 131 T2-w MRIs for six cervical and eleven bladder cancer patients were used. These scans were acquired during four scan-sessions (~20-25 min each) at various time-points. Additionally, 258 T2-w MRIs of the first five prostate cancer patients treated using MRIgRT at our center, acquired during each fraction, were analyzed. Rectums were delineated on all scans. The area of gas within the rectum delineations was identified on each MRI slice using thresholding techniques. The area of gas on each slice of the rectum was used to calculate the inter- and intra-fractional group mean, systematic and random variations along the length of the rectum. The cumulative dose perturbation as a result of the gas was estimated. Two approaches were explored: accounting or not accounting for the gas at the start of the scan-session. RESULTS Intra-fractional variations in rectal gas are small compared to the absolute volume of rectal gas detected for all patient groups. That is, rectal gas is likely to remain stable for periods of 20-25 min. Larger volumes of gas and larger variations in gas volume were observed in bladder cancer patients compared with cervical and prostate cancer patients. For all patients, local cumulative dose perturbations per beam over an entire treatment in the order of 60 % were estimated when gas had not been accounted for in the daily adaption. The calculated dose perturbation over the whole treatment was dramatically reduced in all patients when accounting for the gas in the daily set-up image. CONCLUSION Rectal gas in pelvic cancer patients is likely to remain stable over the course of an MRIgRT fraction, and also likely to reappear in the same location in multiple fractions, and can therefore result in clinically relevant over-dosage in the rectal wall. The over-dosage is reduced when accounting for gas in the daily adaption.

Abstract
BACKGROUND This study summarizes the characteristics of children screened for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and reports the case of 1 child who was diagnosed with SARS-CoV-2 infection in Guangzhou Women and Children's Medical Center and the cases of his family members. MATERIAL AND METHODS The medical records of 159 children who were admitted to our hospital from January 23 to March 20, 2020, were retrospectively analyzed. Samples from pharyngeal or/and anal swabs were subjected to reverse-transcription polymerase chain reaction (RT-PCR) testing for SARS-CoV-2 within 12 h of patient admission; a second RT-PCR test was done 24 h after the first test. RESULTS Of the 159 patients, 151 patients had epidemiological histories, 14 patients had cluster onset, and 8 patients had no epidemiological history but had symptoms similar to coronavirus disease 2019 (COVID-19). The most common symptom was fever (n=125), followed by respiratory and gastrointestinal symptoms. A 7-year-old boy in a cluster family from Wuhan was confirmed with asymptomatic SARS-CoV-2 infection with ground-glass opacity shadows on his lung computed tomography scan, and his swab RT-PCR test had not turned negative until day 19 of his hospitalization. In patients who did not test positive for SARS-CoV-2, influenza, respiratory syncytial virus, and adenovirus were observed. A total of 158 patients recovered, were discharged, and experienced no abnormalities during follow-up. CONCLUSIONS For SARS-CoV-2 nosocomial infections, taking a "standard prevention & contact isolation & droplet isolation & air isolation" strategy can prevent infection effectively. Children with clustered disease need close monitoring.

Abstract
BACKGROUND AND PURPOSE The relationship between glycemic control in patients with type 2 diabetes mellitus and intracranial atherosclerotic plaque features has remained understudied. This study aimed to investigate the association of type 2 diabetes mellitus and glycemic control with the characteristics of intracranial plaques using vessel wall MR imaging. MATERIALS AND METHODS In total, 311 patients (217 [69.8%] men; mean age, 63.24 ± 11.44 years) with intracranial atherosclerotic plaques detected on vessel wall MR imaging were enrolled and divided into 3 groups according to type 2 diabetes mellitus and glycemic control statuses: the non-type 2 diabetes mellitus group, the type 2 diabetes mellitus with good glycemic control group, and the type 2 diabetes mellitus with poor glycemic control group. The imaging features of intracranial plaque were analyzed and compared among the groups. The clinical risk factors for atherosclerosis were also analyzed using logistic regression analysis. RESULTS The plaque length and thickness were significantly higher in the type 2 diabetes mellitus with poor glycemic control group than in the non-type 2 diabetes mellitus group. The prevalence of strongly enhanced plaques was significantly higher in the type 2 diabetes mellitus with poor glycemic control group than in the non-type 2 diabetes mellitus and type 2 diabetes mellitus with good glycemic control groups (92.9%, 63.4%, and 72.7%, respectively; P < .001). Multivariate logistic regression analysis showed a significant association of poor glycemic control with the plaque length (OR = 1.966; 95% CI, 1.170-3.303; P = .011), plaque thickness (OR = 1.981; 95% CI, 1.174-3.340; P = .010), and strongly enhanced plaque (OR = 5.448; 95% CI, 2.385-12.444; P < .001). CONCLUSIONS Poor glycemic control, compared with the history of diabetes, might have a greater impact on the burden and vulnerability of intracranial atherosclerotic plaques.

Abstract
Increasing demands for bioactive compounds have motivated researchers to employ micro‐organisms to produce complex natural products. Currently, Bacillus subtilis has been attracting lots of attention to be developed into terpenoids cell factories due to its generally recognized safe status and high isoprene precursor biosynthesis capacity by endogenous methylerythritol phosphate (MEP) pathway. In this review, we describe the up‐to‐date knowledge of each enzyme in MEP pathway and the subsequent steps of isomerization and condensation of C5 isoprene precursors. In addition, several representative terpene synthases expressed in B. subtilis and the engineering steps to improve corresponding terpenoids production are systematically discussed. Furthermore, the current available genetic tools are mentioned as along with promising strategies to improve terpenoids in B. subtilis, hoping to inspire future directions in metabolic engineering of B. subtilis for further terpenoid cell factory development.

Aortic valve disease is the most common valvular heart disease leading to valve replacement. The efficacy of pharmacological therapy for aortic valve disease is limited by the high mechanical stress at the aortic valves impairing the binding rate. We aimed to identify nanoparticle coating with entire platelet membranes to fully mimic their inherent multiple adhesion mechanisms and target the sclerotic aortic valve of apolipoprotein E-deficient (ApoE−/−) mice based on their multiple sites binding capacity under high shear stress.
Methods
Considering the potent interaction of platelet membrane glycoproteins with components present in sclerotic aortic valves, platelet membrane-coated nanoparticles (PNPs) were synthetized and the binding capacity under high shear stress was evaluated in vitro and in vivo.
Results
Compared with PNPs bound intensity in the static station, 161%, 59%, and 39% of attached PNPs remained adherent on VWF-, collagen-, and fibrin-coated surfaces under shear stress of 25dyn/cm2 respectively. PNPs demonstrated effectively adhering to von Willebrand factor, collagen and fibrin under shear stresses in vitro. In an aortic valve disease model established in ApoE−/− mice, PNPs group exhibited significant increase of accumulation in the aortic valves compared with PBS and control NP group. PNPs displayed high degrees of proximity or co-localization with vWF, collagen and fibrin, which exhibited good targeting to sclerotic aortic valves by mimicking platelet multiple adhesive mechanisms.
Conclusion
PNPs could provide a promising platform for the molecular diagnosis and targeting treatment of aortic valve disease.

Abstract
In this experiment, the conjugation reaction between gluten and maltose via Maillard reaction under dry-heated condition was studied. The process conditions for the preparation of protein-maltose conjugates with optimum solubility were optimized by using Box-Behnken model. The conjugation reaction and the structure changes of the protein-maltose conjugates were confirmed by infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The results showed that the process conditions for the preparation of protein-maltose conjugates with optimum solubility were as follows: temperature 50.72°C, time 1.92 days, and gluten/maltose (W/W) 267.36%. The infrared spectroscopy showed that the structure of the modified protein had a very obvious change, including the decrease in β-fold and β-turn and the increase in α-helix at a certain degree. But the conjugation reaction has little effect on the irregular coiled structure. The scanning electron microscopy showed that the microstructure of gluten is small grainy, but gluten-maltose conjugate looks sheet with bigger volume.

Abstract
AIMS Immunocompromised mice are extensively used in the screening of vaccines and drugs for Cryptosporidium, but this study model does not reflect the real status of infection in immunocompetent animals. This study aimed to provide an optimized animal model for future studies of Cryptosporidium vaccine. METHODS AND RESULTS Three mouse strains (ICR, BALB/c and KM) with or without immunosuppression were compared after challenge with Cryptosporidium tyzzeri (C tyzzeri). The results indicated that ICR mice shed a greater number of faecal oocysts (20 346 ± 203 oocysts/g) compared with BALB/c (2077 ± 142 oocysts/g) and KM mice (3207 ± 431 oocysts/g) after experimental infection with C tyzzeri (P < .001). However, ICR mouse model is uniquely effective for C tyzzeri, not for other Cryptosporidium spp. such as C parvum. ICR mice were then used to determine the immunoreactions and immunoprotection of P23-DNA vaccine (pVAX1-P23) to C tyzzeri experimental infection. The results showed that a significant increase in anti-P23 antibody levels was induced by the pVAX1-P23 vaccine. Compared to pVAX1, TB and blank control mice, pVAX1-P23 immunized mice produced specific spleen cell proliferation as well as enhanced IL-5, IL-12p70 and IFN-γ production in sera. After challenge with 5 × 106 C tyzzeri oocysts, the oocyst shedding of the pVAX1-P23 immunized group was reduced by 69.94% comparing to the infection control. CONCLUSION These results provide an optimized animal model for the study of prophylactic vaccines and this model might be applied to other candidates against Cryptosporidium, not only for pVAX1-P23.

Abstract
Objective: To explore the proportion of obstructive sleep apnea (OSA) in primary aldosteronism (PA) in Chinese population and compare the clinical characteristics between PA patients with OSA and those without. Methods: A total of 96 patients diagnosed with PA from September 2015 to November 2018 were recruited in this study. OSA was screened by cardio-respiratory polygraphy. According to the apnea hypopnea index (AHI), the patients were divided into PA with OSA group (AHI ≥5 times) and PA without OSA group (AHI<5 times). Results: Among all patients (96), 69 (71.9%) were with OSA, among them 22 patients (22.9%) were with mild OSA, 17 patients (17.7%) were with moderate OSA and 30 patients (31.3%) were with severe OSA. Compared with the patients without OSA, the patients with OSA were elder, and had higher levels of body mass index (BMI), waist circumference (WC), hip circumference (HC), creatinine (CR) and glycosylated haemoglobin (HbA1c) (P<0.05), but lower concentrations of plasma aldosterone (PAC), supine aldosterone renin concentration ratio(ARR) and the PAC after the diagnosis test (P<0.05). Spearman correlation analyses showed that BMI, WC, HC, CR and HbA1c were positively correlated with AHI (P<0.05), while high-density lipoproteincholesterol (HDL-C), supine-PAC and saline infusion test(SIT)-post PAC were negatively correlated with AHI (P<0.05). Conclusions: The proportion of OSA in PA patients is relatively high (71.9%). Metabolic abnormalities are more common in PA patients with OSA, indicating that screening for OSA should be carried out routinely in PA patients.

Abstract
Objective: To analyze the clinic features of isolated myeloid sarcoma (IMS) involving the pleural cavity. Methods: A case of pleural isolated myeloid sarcoma (PIMS) with pleural effusion as the first manifestation was described. The related cases in literatures were reviewed with"myeloid sarcoma"and"pleural effusions"as the keywords to search China HowNet, Wanfang database and PubMed database. Results: A 59-year-old man complained of right chest pain for 2 months and worsening pain with distress and shortness of breath for 2 weeks. The chest CT scan showed pleural effusion on the right side. Flow cytometric analysis of pleural fluid showed that a population of blasts with CD34 expressing was 37.6% of the total nucleated cells. The pleural biopsy through medical thoracoscopy indicated lymphoproliferative lesions by pathological examination. Immunohistochemistry was performed on pleural histological sections and cell blocks of pleural effusions, which showed CD34 and CD117 positive expression. The diagnosis of PIMS was finally made. Two literature papers with 2 complete cases were found and reviewed. The 3 cases were analyzed. There were 2 males and 1 female. The age was 59, 51, 56 years respectively. One case was a patient with 3 weeks of right upper quadrant and epigastric pain, nausea, and weight loss. Cytological examination of the pleural fluid showed numerous poorly differentiated malignant cells. Histology from an open laparotomy in duodenal biopsies, gallbladder, and mesenteric lymph nodes supported the diagnosis of IMS. The other case was a patient with 6 weeks of dyspnea and a large swelling in the upper vestibular region. Thoracentesis showed 82% myeloid blasts in the pleural fluid. A gingival biopsy showed a diffuse infiltration by cells with a blastic appearance and supported IMS. Conclusion: PIMS was a very rare cause of pleural effusions. The cytological and histopathological evidences were useful to diagnose IMS involving the pleural cavity.

Short communication: Effect of delaying the first colostrum feeding on small intestinal histomorphology and serum insulin-like growth factor-1 concentrations in neonatal male Holstein calves. J Dairy Sci 2020; 103:12109-12116.

Abstract
The primary objective of this study was to determine the effect of delaying the first colostrum feeding on small intestinal histomorphology and serum insulin-like growth factor-1 (IGF-1) concentrations, and the secondary objective was to characterize the ultrastructure of the small intestine of neonatal calves at 51 h of life. Twenty-seven male Holstein calves were fed pooled, pasteurized colostrum (7.5% of birth body weight; 62 g of IgG/L) at 45 min (0H, n = 9), 6 h (6H, n = 9), or 12 h (12H, n = 9) after birth. At 12 h after their respective colostrum feeding, calves were fed milk replacer at 2.5% of birth body weight per meal and every 6 h thereafter. Blood samples were collected every 6 h using a jugular catheter and analyzed for serum IGF-1 concentrations using an automated solid-phase chemiluminescent immunoassay. At 51 h of life, calves were euthanized to facilitate collection of the duodenum, proximal and distal jejunum, and ileum. All segments of the small intestine were assessed for histomorphology, whereas scanning electron and transmission electron microscopy analyses were conducted only for the proximal jejunum and ileum. The results revealed that there was no overall effect of colostrum feeding time on serum IGF-1 concentrations; however, serum IGF-1 concentrations were influenced by time. Specifically, concentrations of serum IGF-1 at 48 h were 29% greater than concentrations at 0 h of life (312.8 ± 14.85 vs. 241.9 ± 14.06 ng/mL). Although there was no overall effect of colostrum feeding time on all histomorphological measures assessed, treatment × segment interactions were observed. Villi height was 1.4 times greater in the distal jejunum of 0H calves than in 6H and 12H calves, and 0H calves tended to have 1.2 times greater ileal villus height than 12H calves. In addition, 0H calves had 1.2 and 1.3 times greater ileal crypt depth than 6H and 12H calves, respectively, and 1.3 times greater surface area index than 12H calves in the distal jejunum. Qualitative ultrastructural evaluation of small intestinal enterocytes conducted irrespective of colostrum treatment revealed the presence of large vacuoles of electron-dense material, apical mitochondria, and apical canalicular systems in the jejunum and ileum. These results indicate that the calf intestine at 51 h of life contains unique enterocyte characteristics similar to fetal enterocytes and that delaying colostrum feeding may negatively influence intestinal growth and development.

Abstract
Objective: To explore the related factors of premature acute myocardial infarction(AMI), and to compare the the long-term outcomes in patients with and without premature AMI after percutaneous coronary intervention (PCI). Methods: This study was a prospective cohort study.From January 2013 to December 2013, 10 724 consecutive patients with coronary heart disease undergoing PCI in Fuwai Hospital were enrolled. Among them 1 920 patients with the diagnosis of AMI were divided into two groups: premature AMI (man≤50 years old, woman≤60 years old) and non-premature AMI. The baseline characteristics were collected, and multivariate logistic regression was uesed to analysis the related factors of premature AMI. The clinical outcomes, including the major adverse cardiovascular and cerebrovascular events(MACCE) which was the composite of cardiac death, myocardial infarction, revascularization, stroke and stent thrombosis, as well as bleeding events, during hospitalization, at 2 years and 5 years follow-up were analyzed. Results: A total of 1 920 AMI patiens were included(age was (56.5±11.3) years old),with 1 612(84.0%) males. There were statistically significant differences between the two groups in gender, body mass index, blood lipid, complications, inflammatory markers, etc (all P<0.05). Multivariate logistic regression analysis showed body mass index(OR=1.06, 95%CI 1.01-1.10, P<0.01), triglyceride(OR=1.47, 95%CI 1.14-1.90, P<0.01), serum uric acid level(OR=1.02, 95%CI 1.01-1.04, P<0.01), high density lipoprotein cholesterol level(OR=0.33, 95%CI 0.14-0.78, P=0.01) and history of hypertension(OR=0.72, 95%CI 0.56-0.93, P=0.01) were independent related factors of premature AMI. The incidence of all-cause death and cardiac death were lower during hospitalization, at 2 years and 5 years follow-up in the premature AMI group than in non-premature AMI group(all P<0.05). In the premature AMI group, the incidence of MACCE and stroke was lower, with more bleeding events in 5 years follow-up(all P<0.05). Conclusions: Metabolic abnormalities, including high BMI, high triglyceride level and high serum uric acid, low high-density lipoprotein cholesterol level are the related factor of premature AMI. The incidence of ischemic events in patients with premature AMI is lower, while the incidence of bleeding events is higher than non-premature AMI patients.
