Abstract
Objective: To compare the standard percutaneous nephrolithotomy and mini-percutaneous nephrolithotomy in order to determine the optimal tract size for patients with renal stones. Methods: A systematic search of Web of Science, EMBASE, Cochrane Library, and PubMed databases was conducted for articles published through 20 August 2019, reporting on a comparison of the standard percutaneous nephrolithotomy and mini-percutaneous nephrolithotomy using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results: Of 763 studies, 14 were considered for the evidence synthesis. A total of 1980 cases were included. Of these patients, 897 cases underwent standard percutaneous nephrolithotomy, and 1083 cases underwent mini-percutaneous nephrolithotomy. Stone-free rates were 87.6% (786 of 897 patients) for standard percutaneous nephrolithotomy and 87.8% (951 of 1083 patients) for mini-percutaneous nephrolithotomy ( p = 0.57). Tract sizes of 30F and 22–26F in standard percutaneous nephrolithotomy group shorten operation time compared with mini-percutaneous nephrolithotomy ( p = 0.02; p = 0.004; respectively). Leakage ( p = 0.04), bleeding ( p = 0.01), blood transfusion ( p < 0.00001), and renal pelvis perforation ( p = 0.02) were more common in standard percutaneous nephrolithotomy group than in mini-percutaneous nephrolithotomy group. Subgroup analysis showed only blood transfusion for 30F and 22–26F standard percutaneous nephrolithotomy group was more common than mini-percutaneous nephrolithotomy ( p < 0.0001, p = 0.005, respectively). Conclusion: Standard percutaneous nephrolithotomy was associated with higher leakage, bleeding, blood transfusion, and renal pelvis perforation, but had a shorter operation time. Tract size of 30F improved the stone-free rate compared with mini-percutaneous nephrolithotomy, but led to more complications. Tract size of 22–26F was no better than 30F or mini-percutaneous nephrolithotomy.

Abstract
Background:From a cross-sectional cohort, we have identified a candidate human gut anaerobic pathobiont,Ruminococcus gnavus(RG) of the familyLachnospiraceaethat was linked to active Lupus nephritis (LN)(1). Based on 16S rRNA amplicon analysis, LN patients displayed increased fecal RG abundance, concordant with serum IgG anti-RG antibody responses that appeared intertwined with anti-dsDNA responses implicated in renal pathogenesis. Indeed, monocolonization of germ-free mice is reported to result in generalized inflammation and expansions of Th17 cells. However, RG at low levels are also prevalent in healthy adults, and the temporal dynamics of RG representation within Lupus microbiota ecosystems have not been investigated. Also, genomic sequences of few RG strains have been reported, and these vary greatly in genome structure, gene representation and sequence, which may have broad implications for adaptation to a host with systemic inflammation and/or factors that contribute to immune activation in a susceptible host.Objectives:To investigate the relationships betweenin vivoRG expansions and disease activity that often wax and wane overtime, we initiated longitudinal studies in Lupus patients and controls. As representation of RG strains alone might alter pathogenic potential, we also sought to characterize RG strains from active LN patients.Methods:From our cohort, patients were characterized for demographics, clinical disease activity, and serologies including standard autoantibody and complement levels, and anti-bacterial responses of interest. High throughput 16S rRNA amplicon libraries from fecal samples were analyzed using QIIME 2 and DADA2 (1). Also, individual RG colonies were isolated and subjected to whole genome sequencing. Species and strains were then assigned in part based on multi-locus sequence typing and reference guided genomic assemblies.Results:16S rRNA analysis of 34 samples, at 2-4 timepoints from 14 SLE patients, documented highly conserved patterns of gut community representation overtime in 10/14 patients, based in part on unsupervised hierarchical cluster analysis. Notably, independent of vacillations in clinical disease activity of up to 8 SLEDAI points, conserved microbiome phylogenetic abundance/composition was documented at a family level, and the level of amplicon sequence variants that approximate identification of individual species. In pilot studies, from two active lupus nephritis patients hundreds of fecal bacterial colonies were isolated, with initial assignments by 16S rRNA sequence. From highly redundant whole genome sequence analysis, these Lupus-patient fecal colonies were found to distribute into only four distinct RG strains, which differed from reported strains.Conclusion:Our findings suggest that many Lupus patients have little or no detectable perturbations in representation of theLachnospiraceaefamily or abundance of RG species overtime. Moreover, this seeming microbiota stability was documented even in patients with dramatic changes in disease activity. However, these approaches are inadequate to detect shifts between RG strains. In pilot studies we have isolated and characterized the genomes of four unique RG strains from active LN patients, which include variations in gene content and sequence that may have implications for the host-commensal relationship and immune activation. Broadening of these studies to larger number of SLE patients and healthy subjects, with metagenomic surveys of strain representation in genomic shotgun libraries are currently in progress, in coordination with murine colonization testing for immune modulatory properties of individual strains.References:[1]Azzouzet al.Ann Rheum Dis2019 78(7):947-56Disclosure of Interests: :Gregg Silverman Consultant of: Work with industry is unrelated to the topic in this abstract, Doua Azzouz: None declared, Ze Chen: None declared, Jing Deng: None declared, Zhi Li: None declared, David Fenyo: None declared, Alexander Alekseyenko: None declared

Abstract
BACKGROUND AND PURPOSE The chemokine monocyte chemoattractant protein-1 (MCP-1) is involved in the pathogenesis of Alzheimer's disease (AD). This study aimed to investigate whether urinary MCP-1 can distinguish patients with AD, patients with amnestic mild cognitive impairment (aMCI) and cognitively normal (CN) subjects. METHODS A total of 754 participants, including 97 patients with AD, 50 patients with aMCI and 84 age- and sex-matched CN controls as well as a cohort of 523 CN subjects of different ages, were enrolled from five hospitals located in different areas of China. Urinary MCP-1 levels were determined using enzyme-linked immunosorbent assays. The correlations between urinary MCP-1 levels and cognition test scores or age were analysed. The optimal diagnostic sensitivity and specificity were determined using receiver operating characteristic curve analysis. RESULTS In the cohort of CN subjects of different ages, urinary MCP-1 levels increased with ageing and were correlated with age. The urinary MCP-1 levels were higher in females than in males. In the cohort composed of patients with AD, aMCI and age- and sex-matched CN controls, urinary MCP-1 levels were significantly higher in patients with AD and aMCI than in CN controls. There were no differences in urine MCP-1 levels between the AD group and the aMCI group. The urinary MCP-1 levels were correlated with the Mini-Mental State Examination scores and age, and were able to differentiate patients with AD and aMCI from CN subjects. CONCLUSIONS Urinary MCP-1 is a potential biomarker for the diagnosis of AD and aMCI.

Abstract
Objective: To analyze the heritability of coronary heart disease (CHD) among the Chinese twin adults. Methods: A total of 20 477 same-sex twin pairs aged 25 years and older from the Chinese National Twin Registry were interviewed. Structure equation model was used to estimate the heritability of CHD. Results: After adjusting for age and gender, the overall heritability of CHD was 0.75(0.68-0.81). Stratified analyses showed that genetic factors play a more important role in CHD incidence in ≥40 years or female twins. While the development of CHD was mainly influenced by environmental factors in 25-39 years or male twins. Conclusion: CHD is influenced by both genetic and environmental factors and the heritability is high.

Abstract
Support vector machine (SVM) and general regression neural network (GRNN) were used to develop classification models for predicting the antimalarial activity against Plasmodium falciparum. Only 15 molecular descriptors were used to build the classification models for the antimalarial activities of 4750 compounds, which were divided into a training set (3887 compounds) and a test set (863 compounds). For the SVM model, its prediction accuracies are 89.5% for the training set and 87.3% for the test set. For the GRNN model, the prediction accuracies for the two sets are 99.7% and 88.9%, respectively. Both SVC and GRNN models have better prediction ability than the classification model based on binary logistic regression (BLR) analysis. Compared with previously published classification models both SVC and GRNN models are satisfactory in predicting antimalarial activities of compounds with in addition of fewer descriptors.

Abstract
A compound cavity was proposed to achieve both whispering gallery mode (WGM) lasing and random lasing. The WGM-random compound cavity consisted of a random structure with an annular boundary, which was fabricated by a method combining both inkjet printing and metal-assisted chemical etching methods. An ultrathin polymer membrane was attached to the WGM-random compound cavity, forming a polymer laser device. A transformation from WGM lasing to random lasing was observed under optical pumping conditions. The laser performance could be easily tailored by changing the parameter of the WGM-random compound cavity. These results provide a new avenue for the design of integrated light sources for sensing applications.

Abstract
The Intrauterine fetal development process is complicated and affected by many regulating factors such as maternal nutritional status, transcription factors and adipokines. Adipokines are kinds of active substances secreted by adipose tissue, including more than 50 kinds of molecules. To explore the correlation between calf birth weights and adipokines including adiponectin, leptin, visfatin, and IGF-1 in cows venous and venous cord blood. Fifty-four healthy multiparous Chinese Holstein cows were used; in which, cows with a calf weight less than 40 kg were included in group A (n=9); those with a calf weight between 40 kg~45 kg were included in group B (n=25) and ≥45 kg were included in group C (n=20), venous blood and cord venous blood was collected. An ELISA kit was used to evaluate the concentration of adiponectin, leptin, visfatin, and IGF-1, correlations between index-index and index-calf birth weight were analysed. In both cows venous and cord venous blood, adiponectin, leptin, visfatin, and IGF-1 levels were significantly correlated with each other (p⟨0.01), and levels of these adipokines in venous blood were significantly higher than cord venous blood (p⟨0.01). Adiponectin, leptin, visfatin, and IGF-1 in venous cord blood were positively correlated with calf birth weights, and significantly correlated with calf birth weights respectively (p⟨0.01). Our study showed that adiponectin, leptin, and IGF-1 were found in venous blood and cord venous blood, and adiponectin, leptin, and IGF-1 in venous and cord venous blood potentially inter-regulated each other; adiponectin, leptin, and IGF-1 in venous blood were not significantly correlated with calf birth weights, while adiponectin, leptin, visfatin, and IGF-1 in venous cord blood were significantly correlated with calf birth weights, respectively.

Abstract
Objective: To explore the clinical characteristics and genotyping results of childhood-onset myoclonus dystonia syndrome caused by SGCE variants. Methods: The clinical data of 9 children with SGCE-related myoclonus dystonia syndrome admitted at either the Department of Neurology, Beijing Children's Hospital, Capital Medical University or the Department of Pediatrics, Peking University First Hospital from May 2018 to October 2019 were collected and the patients were followed up. The definite diagnosis was made on the basis of whole exome sequencing and multiple ligation-dependent probe amplification. The clinical features and gene test results were analyzed retrospectively. Results: Data of 9 patients (4 boys and 5 girls) diagnosed as myoclonus dystonia syndrome caused by SGCE variants were collected. The onset age ranged from 1 year to 3 years and 2 months. The first symptom was myoclonus in 4 cases, while dystonia in the remaining 5 cases. In the course of the disease, 9 cases had myoclonus and 8 had dystonia. Myoclonic jerks were characterized by involuntary jerks in both upper limbs in 8 patients. Six patients had involuntary jerks of lower limbs, resulting in gait instability or even falling. The myoclonus was exacerbated during the fine motor activities, emotional stress or fatigue. Dystonia was characterized by abnormal gait, including 5 cases with right leg dystonia, and 3 cases with the left leg dystonia. Three probands had a positive family history. Intellectual development was normal in all cases. There was no obvious abnormality in video-electroencephalogram (EEG) during both ictal and interictal periods. Electromyography (EMG) and brain magnetic resonance imaging (MRI) of 9 patients were normal. Nine patients carried SGCE gene variants, including 3 frame shift variants, 2 nonsense variants, 2 missense variants, 1 fragment deletion variant and 1 splice site variant. Seven variants were inherited paternally, and 2 variants were de novo. Madopar was used in 8 patients, and nitrazepam in 4 patients, leading to the decrease in the myoclonus jerks and improvement of gait in 6 and 2 patients, respectively. Conclusions: SGCE gene variants can cause myoclonus dystonia syndrome. The onset of the disease may occur at infancy or preschool age, with either myoclonic jerks or dystonia as the initial symptom. Non-epileptic myoclonus is the prominent symptom, with upper limb mainly involved. Most of the patients have the accompanying symptoms of dystonia, and some of them may have spontaneous symptom relief. SGCE gene is imprinted maternally, and the inherited variants of SGCE are paternal in origin.

Abstract
Objective: To understand and analyze the individual dose level of occupational external exposure of industrial workers in China from 2009 to 2013, and to provide basic data and scientific basis for radiation protection and radiation protection management. Methods: Since January 2009, the individual dose monitoring data of industrial workers were collected through the "National radiological health information platform-individual dose monitoring system". The methods of Kruskal-Wallis test and the Mann-Whitney test were used for statistical analysis of monitoring results for different occupational categories from 2009 to 2013. Results: From 2009 to 2013, a total of 151, 541 people were monitored for the number of industrial radioactive workers, showing a steady upward trend year by year. The average annual effective doses was 1.179 mSv/a. The average annual effective dose of industrial flaw detection, industrial irradiation, luminescent coatings, radioisotope production, logging, accelerator operation and other applications were 0.808, 1.429, 0.315, 1.074, 0.766, 0.576, and 1.510 mSv/a. There was a statistically significant difference in the average annual effective dose between the seven occupational categories (P<0.05) . The average annual effective doses of other application and industrial irradiation workers in 2013 were significantly higher than other occupational categories (P<0.05) . Conclusion: The average annual effective dose of industrial radiation workers meet the requirements of national standards. The exposure doses of industrial radiation and other application radiation workers are relatively high. The radiation protection workplace protection measures should be further improved and improved, and radiation protection knowledge training should be strengthened to protect their occupational health.

Abstract
Objective: To summarize the clinical and genetic characteristics of children with mitochondrial epilepsy. Methods: Clinical data of 62 children who were clinically and genetically diagnosed with mitochondrial epilepsy by the Department of Neurology, Beijing Children's Hospital from October 2011 to December 2018 were analyzed retrospectively, and the control of epilepsy was followed up. T test or χ(2) test were used to analyze the related factors affecting the prognosis of epilepsy between the effective group and the ineffective group. Results: Of the 62 patients, 33 were male and 29 were female. The age of onset was 3.38 (0-12.00) years; for the type of seizures, 68% (42/62) of the patients had focal seizures, generalized or secondary generalized tonic-clonic seizures were seen in 32% (20/62), myoclonic seizures in 23% (14/62), spastic seizures in 7 cases, tonic seizures in 4 cases, absence seizure, atonic seizure and clonic seizure in 1 case each; 16 cases (26%) had status epilepticus, of whom 6 cases had epilepsia partialis continua; 52% (32/62) had 2 or more types of seizures. The clinical phenotypes were mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) in 29 cases, Leigh syndrome (LS) in 11 cases, combined oxidative phosphorylation deficiency in 6 cases, myoclonus epilepsy with ragged-red fibers in 5 cases, Alpers syndrome in 4 cases, pontocerebellar hypoplasia type 6 and mitochondrial DNA depletion syndrome 9 in 2 cases each, mitochondrial complex Ⅰ deficiency nuclear type 20, progressive cavitating leukoencephalopathy, and biotinidase deficiency in 1 case each. Of the 62 cases, 40 cases (65%) had mitochondrial DNA (mtDNA) variations, of which 26 cases had m.3243A>G variants, 6 cases had m.8344A>G variants, and 3 cases had m.8993T>G/C variants, m.3271T>C, m.3481G>A, m.3946G>A, m.13094T>C, m.14487T>C variant was in 1 case each; nuclear DNA (nDNA) variations were identified in 22 cases (35%), of which 7 cases carrying variations in mitochondrial ammonia acyl tRNA synthetase coding gene, mutations in POLG and the gene encoding complex Ⅰ were in 4 cases each, variations in SUCLG1 and SDHA genes were in 2 cases each, and variations in PDHA1, BTD and TRIT1 genes were in 1 case each. Forty-three patients were followed up, and the follow-up time was 20 (3-84) months. According to the follow-up results, the anti-epilepsy treatment was effective in 19 cases (44%) and ineffective in other 24 cases (56%). The onset age of the effective group was 3.42 (0-11.50) years and that of the ineffective group was 0.92 (0-9.50) years. The onset duration of the effective group was 0 (0-7.00) years and that of the ineffective group was 0 (0-4.83) years. There was no significant difference between the effective group and the ineffective group (t=1.662, 0.860; P=0.104, 0.395). In the effective group and the ineffective group, 12 cases and 9 cases used less than 2 kinds of antiepileptic drugs, 7 cases and 15 cases used more than or equal to 2 kinds of antiepileptic drugs, 13 and 15 cases had first epilepsy, 6 and 9 cases had non-first epilepsy, 14 and 11 cases had mtDNA variation, 5 and 13 cases had nDNA variation, respectively. There was no significant difference between the two groups (χ(2)=2.794, 0.164, 3.380; P=0.095, 0.686, 0.066). Conclusions: The types of seizures with mitochondrial epilepsy in children varied, with focal motor seizures being the most common, followed by generalized or secondary generalized tonic-clonic seizures. Most children have more than two types of seizures. MELAS is the most common clinical phenotype, followed by LS; mtDNA variation is the dominant gene variation, of which m.3243A>G variation is the most common hotspot variation, followed by gene variation encoding mitochondrial aminoacyl tRNA synthase.

Abstract
OBJECTIVE We investigated the effects of BMSCs, which was modified by programmed death ligand-1 immunoglobulin (PDL1Ig) gene, on the immunological rejection of orthotopic liver transplantation (OLT) in rats. MATERIALS AND METHODS Rat BMSCs were cultured and modified by recombinant adenovirus pAdEasy-1/PDL1Ig for 72h. The total protein was extracted, and the protein expression of PDL1Ig after transfection was detected by Western blotting. Mixed lymphocyte reaction was applied to detect the inhibitory effect of BMSCs, including pre-transfection and post-transfection, on the cell activity of T lymphocytes in peripheral blood. The male Wistar rats were used as donors, and the male Sprague-Dawley (SD) rats were used as recipients. The improved cuff method was computed in OLT to establish the rat orthotopic liver transplantation model of acute rejection. The rats were randomly divided into 4 groups, including a control group (10 pairs), BMSCs treatment group (10 pairs), BMSCs/GFP (green fluorescent protein) treatment group (10 pairs), and BMSCs/PDL1Ig treatment group (10 pairs). 5 rats in each group were randomly collected and euthanized at day 7 after the operation. The peripheral blood was gathered to detect levels of 3 types of cytokines, including interferon gamma (IFN-g), interleukin-4 (IL-4), and IL-2. In addition, the liver function of rats was checked, and the pathological changes of liver transplantation were observed under the optical microscope. The remaining five rats in every group were used for measuring the survival situation and survival time. RESULTS After BMSCs were modified by a recombinant adenovirus pAdEasy-1/PDL1Ig for 72h, the expression of PDL1Ig in the BMSCs was detected. The inhibitory effects of BMSCs/PDL1Ig on the cell activity of lymphocytes were stronger than that of BMSCs/GFP. The levels of IL-4 in BMSCs/PDL1Ig group were significantly higher than those in the other 3 groups, and the levels of IFN-g and IL-2 were significantly decreased (p<0.05). The liver function of 4 groups was measured at day 7 after transplantation. Our results showed that the liver function in BMSCs/PDL1Ig group was most significantly improved, and the levels of ALT, AST, and TBil almost recovered to normal. The differences were statistically significant compared to the control group, BMSCs treatment group, and BMSCs/GFP treatment group. Results of pathological examination of liver tissue showed that the control group underwent severe rejection of liver transplantation. The BMSCs treatment group and BMSCs/GFP treatment group also rejected the liver transplantation, but the degree was lighter when compared to the control group. In addition, there was almost no rejection of liver transplantation in the BMSCs/PDL1Ig group. The recipient survival time of most rats was more than 100d, which was significantly longer than the other 3 groups (p<0.05). CONCLUSIONS PDL1Ig-modified BMSCs can inhibit the rejection of liver transplantation in rats, induce the formation of the immune tolerance of liver transplantation, and the effect was more significant than that of BMSCs alone.

Abstract
Objective:Esthesioneuroblastoma(ENB) is a sinonasal rare tumor, and the assessment on the prognosis have not been used with on consensus, our study aims to set an accuracy indicator to predict the outcomes of ENB.Method:A retrospective review was performed on 31 ENB patients. We collected 31 patients with ENB and reviewed the clinical data and pathological slides; modified Kadish stages were evaluated by otolaryngologist and imaging specialist; Hyams grading system were confirmed by two pathologists, who reviewed and paid attention to the pathological characteristics of Hyams grading system. Finally, the relation among the clinical data, pathological features and clinical outcome of these 31 ENB were analyzed by Kaplan-Meier method.Result: The Hyams grading system and modified Kadish stage were considered together seemed to evaluate the prognosis of ENB more accurately, when the scores over 6 points, the patients had the poor prognosis with the mean median survival months of 24.67±32.22, compared with the scores under 6 and the final scores reached at 4, 5, 6, 7, 8, the tumor metastasis rates were 14.3%, 16.7%, 33.3%, 50.0%, 100.0% respectively.Conclusion:Taking the Hyams grading system and modified Kadish stage into consideration, which may evaluate the prognosis of ENB more accurately.

Abstract
Herein, a quantum dot random laser was achieved using a silicon nanowire array. The silicon nanowire array was grown by a metal-assisted chemical etching method. A colloidal quantum dot solution was spin-coated on silicon nanowires to form the random laser. The performance of the random laser was controlled by the resistivity of silicon wafers and the length of silicon nanowires. A transition from incoherent random lasing to coherent random lasing was obtained by increasing the resistivity of the silicon wafers. The random lasing threshold increased with an increase in the length of the silicon nanowires. These results may be useful to explore high-performance silicon-based random lasers.

Abstract
The Chinese National Twin Registry (CNTR) currently includes data from 61 566 twin pair from 11 provinces or cities in China. Of these, 31 705, 15 060 and 13 531 pairs are monozygotic, same-sex dizygotic and opposite-sex dizygotic pairs, respectively, determined by opposite sex or intrapair similarity. Since its establishment in 2001, the CNTR has provided an important resource for analysing genetic and environmental influences on chronic diseases especially cardiovascular diseases. Recently, the CNTR has focused on collecting biologic specimens from disease-concordant or disease-discordant twin pairs or from twin pairs reared apart. More than 8000 pairs of these twins have been registered, and blood samples have been collected from more than 1500 pairs. In this review, we summarize the main findings from univariate and multivariate genetic effects analyses, gene-environment interaction studies, omics studies exploring DNA methylation and metabolomic markers associated with phenotypes. There remains further scope for CNTR research and data mining. The plan for future development of the CNTR is described. The CNTR welcomes worldwide collaboration.
