Abstract
OBJECTIVE Postsurgical seizure freedom in drug-resistant epilepsy (DRE) patients varies from 30% to 80%, implying that in many cases the current approaches fail to fully map the epileptogenic zone (EZ). We aimed to advance a novel approach to better characterize epileptogenicity and investigate whether the EZ encompasses a broader epileptogenic network (EpiNet) beyond the seizure zone (SZ) that exhibits seizure activity. METHODS We first used computational modeling to test putative complex systems-driven and systems neuroscience-driven mechanistic biomarkers for epileptogenicity. We then used these biomarkers to extract features from resting-state stereoelectroencephalograms recorded from DRE patients and trained supervised classifiers to localize the SZ against gold standard clinical localization. To further explore the prevalence of pathological features in an extended brain network outside of the clinically identified SZ, we also used unsupervised classification. RESULTS Supervised SZ classification trained on individual features achieved accuracies of .6-.7 area under the receiver operating characteristic curve (AUC). Combining all criticality and synchrony features further improved the AUC to .85. Unsupervised classification discovered an EpiNet-like cluster of brain regions, in which 51% of brain regions were outside of the SZ. Brain regions in the EpiNet-like cluster engaged in interareal hypersynchrony and locally exhibited high-amplitude bistability and excessive inhibition, which was strikingly similar to the high seizure risk regime revealed by our computational modeling. SIGNIFICANCE The finding that combining biomarkers improves SZ localization accuracy indicates that the novel mechanistic biomarkers for epileptogenicity employed here yield synergistic information. On the other hand, the discovery of SZ-like brain dynamics outside of the clinically defined SZ provides empirical evidence of an extended pathophysiological EpiNet.

Abstract
Barrierless bond dissociation reactions play an important role in fuel combustion. In this work, the pressure-dependent dissociation rate constants of ethylamine (EA) are accurately determined using variable-reaction-coordinate variational transition-state theory combined with the system-specific quantum Rice-Ramsperger-Kassel method. Before the kinetics calculations, the performances of four density functional theory methods in describing the bond dissociation of EA are evaluated against the benchmark method, FIC-MRCISD(T)+Q/cc-pVTZ, and the MN15-L/cc-pVTZ method is the best choice. By comparison of the Gibbs free energies and the rate constants for the bond dissociation reactions of EA, ethanol, and propane, the influence of functional groups on the reaction kinetics is discussed. The kinetics calculations show that the dissociation rate constants of EA are sensitive to pressure at low pressures and high temperatures, and the dominant channel is the reaction that yields C2H5 and NH2 radicals. A literature combustion model of EA is updated with our calculations, and the satisfactory agreement between the model predictions and reported ignition delay times of EA suggests the reliability of our calculations.

Abstract
Objective: To exploring the regulatory effect of miR-29a on the transforming growth factor-β1 (TGF-β1) /Smad homolog 3 (Smad3) pathway during the process of rare earth neodymium oxide (Nd(2)O(3)) induced pulmonary fibrosis in mice. Methods: In March 2021, 72 SPF grade C57/BL6J male mice were selected and randomly divided into a control group, Nd(2)O(3) group, Nd(2)O(3)+miR-29a agomir group, and Nd(2)O(3)+NC agomir group, with 18 mice in each group. The Nd(2)O(3) group, Nd(2)O(3)+miR-29a agomir group, and Nd(2)O(3)+NC agomir group were treated with non exposed tracheal instillation, with a dust concentration of 250 mg/ml and a dust volume of 0.1 ml. The control group was given the same volume of physiological saline. After exposure to Nd(2)O(3), 0.1 ml (5 nmol) of miR-29a agomir was injected into the tail vein of mice in the Nd(2)O(3)+miR-29a agomir group every 3 days, while 0.1 ml of NC agomir was injected into the tail vein of mice in the Nd(2)O(3)+NC agomir group. On the 7 th, 14 th, and 28 th days after dust exposure, 6 mice were killed in each group, and the lung tissue of the mice was taken out. HE staining was used to observe the pathological status of the mouse lung tissue; ELISA method was used to detect the levels of TGF-β1 and connective tissue growth factor (CTGF) in lung tissue; Use qRT-PCR detection method to detect the expression level of TGF-β1 mRNA; Using immunofluorescence assay to detect the expression level of Smad3 in mouse lung tissue; Use bioinformatics websites such as TargetScan7 and miRDB to predict the target gene of miR-29a. When the metrological date were satisfied with normal distribution, Mean±SD was used for comparison between groups, t test was used for two indepent samples, and LSD method was used when the variance was homogeneity in pairwise comparison. Results: HE staining showed that the Nd(2)O(3) group of mice showed obvious infiltration of inflammatory cells and structural disorder of alveoli in the early stage of lung tissue. At 28 days, the collagen fibers in the mouse lung tissue increased and the lung tissue showed fibrotic honeycomb like changes. The degree of pulmonary fibrosis in the Nd(2)O(3)+miR-29a agomir group of mice was significantly reduced; The content of TGF-β1 and CTGF in the lung tissue of mice in the Nd(2)O(3)+miR-29a agomir group was lower than that in the Nd(2)O(3)+NC agomir group (P<0.05) ; The relative expression level of TGF-β1 in the lung tissue of mice in the Nd(2)O(3)+miR-29a agomir group was lower than that in the Nd(2)O(3)+NC agomir group (P<0.05) ; The expression level of Smad3 in the nucleus of the Nd(2)O(3)+miR-29a agomir group was lower than that of the Nd(2)O(3)+NC agomir group (P<0.05). The prediction results of bioinformatics websites have found 152 downstream target genes related to miR-29a, among which FBN1, MAP2K6, KPNB1, COL1A2, SNIP1, LAMC1, and SP1 genes may be related to the regulatory effect of miR-29a on TGF-β1/Smad3 signaling pathway. Conclusion: miR-29a may affect lung fibrosis induced by rare earth Nd(2)O(3) exposure in mice by regulating TGF-β1/Smad3 signaling pathway. Overexpression of miR-29a may inhibit TGF-β1/Smad3 signaling pathway and reduce the degree of pulmonary fibrosis in mice.

Abstract
The classic brain criticality hypothesis postulates that the brain benefits from operating near a continuous second-order phase transition. Slow feedback regulation of neuronal activity could, however, lead to a discontinuous first-order transition and thereby bistable activity. Observations of bistability in awake brain activity have nonetheless remained scarce and its functional significance unclear. Moreover, there is no empirical evidence to support the hypothesis that the human brain could flexibly operate near either a first- or second-order phase transition despite such a continuum being common in models. Here, using computational modeling, we found bistable synchronization dynamics to emerge through elevated positive feedback and occur exclusively in a regimen of critical-like dynamics. We then assessed bistability in vivo with resting-state MEG in healthy adults (7 females, 11 males) and stereo-electroencephalography in epilepsy patients (28 females, 36 males). This analysis revealed that a large fraction of the neocortices exhibited varying degrees of bistability in neuronal oscillations from 3 to 200 Hz. In line with our modeling results, the neuronal bistability was positively correlated with classic assessment of brain criticality across narrow-band frequencies. Excessive bistability was predictive of epileptic pathophysiology in the patients, whereas moderate bistability was positively correlated with task performance in the healthy subjects. These empirical findings thus reveal the human brain as a one-of-a-kind complex system that exhibits critical-like dynamics in a continuum between continuous and discontinuous phase transitions.SIGNIFICANCE STATEMENT In the model, while synchrony per se was controlled by connectivity, increasing positive local feedback led to gradually emerging bistable synchrony with scale-free dynamics, suggesting a continuum between second- and first-order phase transitions in synchrony dynamics inside a critical-like regimen. In resting-state MEG and SEEG, bistability of ongoing neuronal oscillations was pervasive across brain areas and frequency bands and was observed only with concurring critical-like dynamics as the modeling predicted. As evidence for functional relevance, moderate bistability was positively correlated with executive functioning in the healthy subjects, and excessive bistability was associated with epileptic pathophysiology. These findings show that critical-like neuronal dynamics in vivo involves both continuous and discontinuous phase transitions in a frequency-, neuroanatomy-, and state-dependent manner.

Abstract
Objective: To evaluate the activity of six β-lactams in combination with three β-lactamase inhibitors against mycobacterium tuberculosis(MTB) in vitro. Methods: A total of 105 multidrug-resistant tuberculosis (MDR-TB) strains from different regions of Henan province from January to September 2020 were included in this study. Drug activity of six β-lactams (biapenem, meropenem, imipenem, doripenem, ertapenem and tebipenem) alone or in combination with β-lactamase inhibitors (clavulanic acid, avibactam and relebactam) was examined by minimum inhibitory concentration method (MICs) against 105 clinical isolates. Mutations of blaC, ldtmt1 and ldtmt2 were analyzed by PCR and DNA sequencing. Chi-square test was used to compare the antimicrobial activities of different β-lactam drugs. Results: Out of the β-lactams used herein, tebipenem was the most effective against MDR-TB and had an MIC50 value of 8 mg/L(χ2=123.70,P=0.001). Besides, after the addition of β-lactamase inhibitors, the MICs of most β-lactam drugs were reduced more evidently in the presence of avibactam and relebactam compared to clavulanic acid.Especially, relebactam decreased both the MIC50 and MIC90 of telbipenem by 16-fold, and diluted the MIC of 23 (21.90%) and 41 (39.04%) isolatesby 32-fold and 16-fold.In addition, a total of 13.33% (14/105) of isolates harbored mutations in the blaC gene, with three different nucleotide substitutions: AGT333AGG, AAC638ACC and ATC786ATT. For the strains with Ser111Arg and Asn213Thr substitution in BlaC, the MIC values of the meropenem-clavulanate combination were reduced compared with a synonymous single nucleotide polymorphism (SNP) group. Conclusions: Both avibactam and relebactam had better synergistic effects on β-lactams than clavulanic acid. The combination of tebipenem and relebactam showed the most potent activity against MDR-TB isolates. In addition, the Ser111Arg and Asn213Thr substitution of BlaC may be associated with an increased susceptibility of MDR-TB isolates to meropenem in the presence of clavulanate.

Abstract
Neuronal oscillations and their synchronization between brain areas are fundamental for healthy brain function. Yet, synchronization levels exhibit large inter-individual variability that is associated with behavioral variability. We test whether individual synchronization levels are predicted by individual brain states along an extended regime of critical-like dynamics - the Griffiths phase (GP). We use computational modelling to assess how synchronization is dependent on brain criticality indexed by long-range temporal correlations (LRTCs). We analyze LRTCs and synchronization of oscillations from resting-state magnetoencephalography and stereo-electroencephalography data. Synchronization and LRTCs are both positively linearly and quadratically correlated among healthy subjects, while in epileptogenic areas they are negatively linearly correlated. These results show that variability in synchronization levels is explained by the individual position along the GP with healthy brain areas operating in its subcritical and epileptogenic areas in its supercritical side. We suggest that the GP is fundamental for brain function allowing individual variability while retaining functional advantages of criticality.

Abstract
From 1950 to 1970, under the leadership of the central government, workstations for the prevention and control of schistosomiasis were established in the southern Anhui region. In terms of controlling the source of the disease, light and severe epidemic areas were scientifically divided. By opening new ditches to replace old ones, changing paddy fields to dry fields, and using traditional Chinese medicine and Western medicine to prevent the intermediate host of schistosomiasis, oncomelania from surviving. By managing the feces from human and animals and controlling the water source, the transmission route of schistosome eggs has been effectively cut off. At the same time, the education of hygiene awareness among susceptible populations were strengthened. In terms of diagnosis, modern physical and biochemical detection were used to improve the accuracy of diagnosis. In terms of treatment, by combining traditional Chinese medicine and Western medicine, together with the splenectomy, the cure rates were improved. In the process of preventing and controlling schistosomiasis, the governments of Anhui Province and the southern region of Anhui Province achieved good results, providing useful reference for the prevention and control of other diseases.

Abstract
Objective: To investigate the role of Keap1/Nrf2/HO-1 signaling pathway in liver injury induced by neodymium oxide (Nd(2)O(3)) in mice. Methods: In March 2021, forty-eight SPF grade healthy male C57BL/6J mice were randomly divided into control group (0.9% NaCl), low dose group (62.5 mg/ml Nd(2)O(3)), medium dose group (125.0 mg/ml Nd(2)O(3)), and high dose group (250.0 mg/ml Nd(2)O(3)), each group consisted of 12 animals. The infected groups were treated with Nd(2)O(3) suspension by non-exposed tracheal drip and were killed 35 days after dust exposure. The liver weight of each group was weighed and the organ coefficient was calculated. The content of Nd(3+) in liver tissue was detected by inductively coupled plasma mass spectrometry (ICP-MS). HE staining and immunofluorescence was used to observe the changes of inflammation and nuclear entry. The mRNA expression levels of Keap1, Nrf2 and HO-1 in mice liver tissue were detected by qRT-PCR. Western blotting was used to detect the protein expression levels of Keap1 and HO-1. The contents of catalase (CAT), glutathione peroxidase (GSH-Px) and total superoxide dismutase (T-SOD) were detected by colorimetric method. The contents of interleukin 1β (IL-1β), interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) were determined by ELISA. The data was expressed in Mean±SD. Two-independent sample t-test was used for inter-group comparison, and one-way analysis of variance was used for multi-group comparison. Results: Compared with the control group, the liver organ coefficient of mice in medium and high dose groups were increased, and the Nd(3+) accumulation in liver of mice in all dose groups were significantly increased (P<0.05). Pathology showed that the structure of liver lobules in the high dose group was slightly disordered, the liver cells showed balloon-like lesions, the arrangement of liver cell cords was disordered, and the inflammatory exudation was obvious. Compared with the control group, the levels of IL-1β and IL-6 in liver tissue of mice in all dose groups were increased, and the levels of TNF-α in liver tissue of mice in high dose group were increased (P<0.05). Compared with the control group, the mRNA and protein expression levels of Keap1 in high dose group were significantly decreased, while the mRNA expression level of Nrf2, the mRNA and protein expression levels of HO-1 were significantly increased (P<0.05), and Nrf2 was successfully activated into the nucleus. Compared with the control group, the activities of CAT, GSH-Px and T-SOD in high dose group were significantly decreased (P<0.05) . Conclusion: A large amount of Nd(2)O(3) accumulates in the liver of male mice, which may lead to oxidative stress and inflammatory response through activation of Keap1/Nrf2/HO-1 signal pathway. It is suggested that Keap1/Nrf2/HO-1 signal pathway may be one of the mechanisms of Nd(2)O(3) expose-induced liver injury in mice.

Abstract
Objective: To explore the clinical and chest computed tomography (CT) features and the outcome of immune checkpoint inhibitor-related pneumonitis (CIP). Methods: Clinical and chest CT data of 38 CIP patients with malignant tumors from the Cancer Hospital, Chinese Academy of Medical Sciences between August 2017 and April 2021 were retrospectively reviewed, and the outcomes of pneumonitis were followed up. Results: The median time from the administration of immune checkpoint inhibitors (ICIs) to the onset of CIP was 72.5 days in 38 patients with CIP, and 22 patients developed CIP within 3 months after the administration of ICIs. The median occurrence time of CIP in 24 lung cancer patients was 54.5 days, earlier than 119.0 days of non-lung cancer patients (P=0.138), with no significant statistical difference. 34 patients (89.5%) were accompanied by symptoms when CIP occurred. The common clinical symptoms were cough (29 cases) and dyspnea (27 cases). The distribution of CIP on chest CT was asymmetric in 31 cases and symmetrical in 7 cases. Among the 24 lung cancer patients, inflammation was mainly distributed ipsilateral to the primary lung cancer site in 16 cases and diffusely distributed throughout the lung in 8 cases. Ground glass opacities (37 cases) and consolidation (30 cases) were the common imaging manifestations, and organizing pneumonia (OP) pattern (15 cases) was the most common pattern. In 30 CIP patients who were followed up for longer than one month, 17 cases had complete absorption (complete absorption group), and 13 cases had partial absorption or kept stable (incomplete absorption group). The median occurrence time of CIP in the complete absorption group was 55 days, shorter than 128 days of the incomplete absorption group (P=0.022). Compared with the incomplete absorption group, there were less consolidation(P=0.010) and CIP were all classified as hypersensitivity pneumonitis (HP) pattern (P=0.004) in the complete absorption group. Conclusions: CIP often occurs within 3 months after ICIs treatment, and the clinical and CT findings are lack of specificity. Radiologic features may have a profound value in predicting the outcome of CIP.

Abstract
Yin Chan Quan Shu (Obstetrics and gynecology monograph) is a monograph on obstetrics and gynecology compiled by Wang Kentang in the Ming Dynasty. It had four volumes and was published in the thirtieth year of Wanli (1602) in the Ming Dynasty after it was edited by Zhang Shoukong and others. It was found that Yin Chan Quan Shu has four versions remaining. They were the version printed by Shu Lin Qiao Shan Tang in the Ming Dynasty, held in the National Library of China and the Cabinet Library of Japanese Official Documents Library; the version revised according to the version of Shu Lin Qiao Shan Tang, held in the Library of Capital Medical University, Tianjin Medical College, Shanghai Branch of the Chinese Medical Association, the Library of Guangzhou University of Chinese Medicine and the Cabinet Library of the National Archives of Japan; the version based on the version of Shu Lin Qiao Shan Tang in the Ming Dynasty, transcribed in the fourth year of Wen Hua (1807), collected in the Cabinet Library of the National Archives of Japan; the version transcribed according to the revised version in the Ming Dynasty, collected in the Shanghai Branch of the Chinese Medical Association. It was found that there was no evidence to support the existence of the so-called "version of Kangxi in the Qing Dynasty". This means almost all versions remaining came from the versions published in the Ming Dynasty. The references of Yin Chan Quan Shu came from Pulse Classic (Mai Jing), Chan Bao, Fu Ren Da Quan Liang Fang and other works with the supplement and development by Wang Kentang.Yin Chan Quan Shu was the main sources and foundation of the Criteria of Syndrome Identification and Treatment in Gynecology (Nv Ke Zheng Zhi Zhun Sheng) by Wang Kentang.

Abstract
Objective: To explore the effects of Nd(2)O(3) exposure to rare earth particles on the secretion of sex hormones, cytochrome P450 family member 11A1 (CYP11A1) , spermatogenesis markers promyelocytic leukemia zinc finger protein (PLZF) and retinoic acid stimulating gene 8 (STRA8) protein in C57 BL/6J male mice. Methods: In March 2021, Forty-eight male C57 BL/6J mice aged 6-8 weeks divided into control group and Nd(2)O(3) exposure low, medium and high dose groups (exposing doses of 62.5, 125.0, 250.0 mg/ml Nd(2)O(3)) , 12 per group. The mice in the Nd(2)O(3) groups were perfused with different doses of Nd(2)O(3) suspension by a one-time non-exposing tracheal instillation method, and the control group was perfused with an equal volume of normal saline, with a volume of 0.1 ml, to establish a mouse reproductive function injury model. After 28 days of exposure, the mice's body weight, testes and epididymis were weighed, and the organ coefficients were calculated; the two epididymis were taken to make a sperm suspension to determine the sperm count, survival rate, and deformity rate; inductively coupled plasma mass spectrometry (ICP-MS) method was used to detect the content of Nd in mouse testis tissue; HE staining was used to detect testicular tissue pathological changes and quantitative analysis; enzyme-linked immunosorbent assay (ELISA) method was used to detect serum luteinizing hormone (LH) and follicle stimulating hormone (FSH) and testosterone (T) content; western blot was used to detect the protein levels of CYP11A1, PLZF and STRA8 in testicular tissues. Results: Compared with the control group, with the increase of the exposure dose, the Nd content in the testis of the mice showed an increasing trend, the sperm survival rate and LH showed a decreasing trend, and the sperm deformity rate showed an increasing trend (P<0.05) ; Pathological showed that the number of sperm in the seminiferous tubules of the testicular tissue in the Nd(2)O(3) medium and high dose groups was significantly reduced, and the germinal epithelial disintegration, intraepithelial vacuolization, and exfoliation of spermatogenic cells and supporting cells occurred; The height of germinal epithelium was significantly reduced, and the percentage of damaged seminiferous tubules showed an increasing trend (P<0.05) ; FSH and T levels in serum in the middle and high dose groups of Nd(2)O(3), and CYP11A1, PLZF and STRA8 proteins in testicular tissues showed a downward trend with increasing dose (P<0.05) . Conclusion: The rare earth particulate Nd(2)O(3) may interfere with the expression of CYP11A1, PLZF and STRA8 protein, thereby causing the disorder of sex hormone secretion in the body, the maintenance of spermatogonia and the obstruction of the process of meiosis, causing reproductive function damage.

Abstract
Objective: To analyze the performance of emergency response to 2019 novel coronavirus (2019-nCoV) positive cases in an international test competition in an Winter Olympic Game venue and provide evidences for the COVID-19 prevention and control in similar competitions. Methods: A retrospective analysis on the epidemiological investigation and nucleic acid test results of the cases, the implementation of prevention and control measures, including the communication with sport teams and others, was conducted. Results: The positive cases of 2019-nCoV among entering people were detected before entry, at airport, hotel and venue. Two positive cases were reported before entry, 2 positive cases infected previously and 3 asymptomatic cases were reported after the entry. The venue public health team and local CDC conducted epidemiological investigation and contact assessment jointly in a timely and efficient manner. No local secondary transmission occurred, but the nucleic acid test results of positive persons fluctuated, posing serious challenges to the implementation of prevention and control measures. Conclusion: In large scale international competition, there is high risk of imported COVID-19. It is necessary to fully consider the fluctuation of nucleic acid test results, the criteria for determination and cancellation of positive results and give warm care to positive cases in the emergency response.

Abstract
Shiguzhai Hui Ju Jian Bian Dan Fang, was the only medical book for prescription and formula collected and compiled by Wu Mianxue in the period of the Wanli in the Ming Dynasty (1573-1620). It had seven volumes in total with six of them popular at that time. The volumes contained 1,460 folk formula and clinical prescriptions which were divided into 111 categories based on their corresponding symptoms of diseases. The set was issued in the beginning of the 17th century, with only three subsets of the volumes left in China today. The three remained versions were the subset of volumes 4-5 left in the Ming Dynasty in the Medical College of Tianjin, the subset of volumes 1-2 and 6-7, with preface, left in the seventeenth of the Shun Zhi Period in the Qing Dynasty (1660) in the Shanghai University of Chinese Medicine and the subset of volumes 4 and 6-7 from time unknown. Additionally, three unabridged versions were found in the Cabinet Library of the National Archives of Japan. They were the Ming version with preface of the seventeenth of the Shun Zhi Period in the Qing Dynasty and a hand-copied version left in the Edo period. It was found that the preface in the seventeenth of the Shun Zhi Period in the Qing Dynasty in both of these versions in China as well as the version in Japan, were counterfeit. The main texts in these versions were edited according to the Ming version. The hand-copied version in Japan was transcribed by Kasahara Eisan and edited by Tanba Motoken according to the Ming version in the late Edo Period.

Abstract
Arsenic is a non-metallic element, and the International Agency for Research on Cancer has identified arsenic and its compounds as carcinogens. Arsenic and its compounds can be absorbed through the respiratory tract, skin and digestive tract, distributed in the liver, kidney, lung and skin, and cause damage. Non-coding RNAs are closely related to arsenic-induced nervous system disorders, cell necrosis, reproductive toxicity, and carcinogenesis. In recent years, the network regulation of microRNAs (miRNAs) , long non-coding RNAs (lncRNAs) , and circular RNAs (circRNAs) among non-coding RNAs in various diseases induced by arsenic has become a new research field. This paper summarizes the existing scientific research results, and expounds the mechanism of miRNAs, lncRNAs and circRNAs in arsenic toxicity, and provides basic data and theoretical basis for the prevention and treatment of arsenic poisoning.

Abstract
Objective: To analyze the safety and efficacy of combined left atrial appendage (LAA) and patent foramen ovale (PFO) closure in adult atrial fibrillation (AF) patients complicating with PFO. Methods: This study is a retrospective and cross-sectional study. Seven patients with AF complicated with PFO diagnosed by transesophageal echocardiography (TEE) in Zhoupu Hospital Affiliated to Shanghai University of Medicine & Health Sciences from June 2017 to October 2020 were selected. Basic data such as age, gender and medical history were collected. The atrial septal defect or PFO occluder and LAA occluder were selected according to the size of PFO, the ostia width and depth of LAA. Four patients underwent left atrial appendage closure(LAAC) and PFO closure at the same time. PFO closure was performed during a one-stop procedure of cryoablation combined with LAAC in 2 patients. One patient underwent PFO closure at 10 weeks after one-stop procedure because of recurrent transient ischemic attack (TIA). All patients continued to take oral anticoagulants. TEE was repeated 8-12 weeks after intervention. In case of device related thrombus(DRT), TEE shall be rechecked 6 months after adjusting anticoagulant and antiplatelet drug treatment. Patients were follow-up at 1, 3, 6, 12, 24 months by telephone call, and the occurrence of cardio-cerebrovascular events was recorded. Results: Among the 7 patients with AF, 2 were male, aged (68.0±9.4) years, and 3 had a history of recurrent cerebral infarction and TIA. Average PFO diameter was (3.5±0.8)mm. Three patients were implanted with Watchman LAA occluder (30, 30, 33 mm) and atrial septal defect occluder (8, 9, 16 mm). 2 patients were implanted with LAmbre LAA occluder (34/38, 18/32 mm) and PFO occluder (PF1825, PF2525). 2 patients were implanted with LACbes LAA occluder (24, 28 mm) and PFO occluder (PF2525, PF1825) respectively. The patients were followed up for 12 (11, 24) months after operation. TEE reexamination showed that the position of LAA occluder and atrial septal defect occluder or PFO occluder was normal in all patients. DRT was detected in 1 patient, and anticoagulant therapy was adjusted in this patient. 6 months later, TEE showed that DRT disappeared. No cardiovascular and cerebrovascular events occurred in all patients with AF during follow-up. Conclusions: In AF patients complicated with PFO, LAAC combined with PFO closure may have good safety and effectiveness.

Abstract
Information regarding the correct pedigree of and relationship between animals is useful for managing dairy breeding, reducing inbreeding, estimating breeding value, and establishing correct breeding programs. Additionally, the successful implementation of progeny testing is crucial for improving the genetics of dairy cattle, which depends on the availability of correct pedigree information. Incorrect pedigree information leads to bias in bull evaluation. In this study, Neogen GeneSeek Genomic Profiler (GGP) 50K SNP chips were used to identify and verify the sire of Taiwanese Holstein dairy cattle and analyze the reasons that lead to incorrect sire records. Samples were collected from 2,059 cows of 36 dairy farms, and the pedigree information was provided by breeders. The results of sire verification can be divided into three categories: submitted unconfirmed sire, submitted confirmed sire, and incorrectly submitted verified sire. Data on the sires of 1,323 (64.25%) and 572 (27.78%) dairy cows were verified and discovered, respectively. Sires of 1,895 (92.03%) dairy cattle were identified, which showed that the paternal pedigree of dairy cattle could be discovered and verified through genetic testing. An error-like analysis revealed that the data of 37 sires were incorrectly recorded because the bull's NAAB code number was incorrectly entered into the insemination records: for 19 sires, the wrong bull was recorded because the frozen semen of a bull placed in the wrong storage tank was used, 6 had no sire records, and for 12 sires, the NAAB code of the correct bull was recorded but with a wrong stud code, marketing code, or unique number for the stud or breed. To reduce recorded sire error rates by at least 27.78%, automated identification of the mated bull must be adopted to reduce human error and improve dairy breeding management on dairy farms.

Abstract
San Xiao Lun is a posthumous manuscript by Liu Wansu. It discussed the etiology, pathogenesis and therapeutic principles of diabetes with special prescriptions for it. Most references in this book came from the works of Liu Wansu himself and some of them came from the works of other sources, such as The Internal Cannon of Medicine. It can be seen that it was a book with Liu Wansu's rethinking and summerising about diabetes after he completed his other works. San Xiao Lun was first published in Ru Men Shi Qin in the Jin Dynasty. It was also cited by Yi Fang Lei Ju in Korea in 1445. It was fully recorded and published in Ru Men Shi Qin in the Wanli Period in the Ming Dynasty and therefore, became the basic version of the current one. After that, it envolved into Si Ku Quan Shu. In the end of the Qing Dynasty, this book was published independently with the comments by Zhou Xuehai, being one of the books in the Zhous' Series Medical Books(Zhou Shi Yi Xue Cong Shu).

Abstract
Objective: To explore the latest progress of oncology drug clinical trials in China under COVID-19, as well as to provide decision-making evidence for related stakeholders. Research progress of oncology drug trials and approved cancer drugs in China in 2020 were systematically summarized and compared with 2019. Methods: Information Disclosure Platform for Drug Clinical Studies and China Food and Drug Administration Query System for Domestic and Imported Drug were searched for registered clinical trials and approved oncology drugs, respectively. The trial scope, stage, drug type, effect and mechanism of domestic and global pharmaceutical enterprises were compared between 2019 and 2020. Results: A total of 722 cancer drug trials registered in China in 2020, with an annual growth rate of 52.3%, accounting for 28.3% of all registered trials. Among them, 603 (83.5%) trials were initiated by domestic pharmaceutical enterprises, and 105 (14.5%) were international multicenter trials, phase I trials accounted for 44.5%. For all those trials, there were 458 cancer drug varieties, with an annual growth rate of 36.7%, and 361 (85.8%) were developed by domestic enterprises. Most of the investigational products were therapeutic innovative drugs (77.1%), major in tumor treatment (92.8%). In terms of mechanism, targeted drugs were the most popular, accounting for 76.6%, and programmed cell death-1 (PD-1) and epithelial growth factor receptor (EGFR) were the most common targets. In addition, there were 19 anticancer drugs from 17 companies approved in China in 2019, with 10 drugs from domestic companies. Lung cancer and breast cancer are the most common indications for both registered trials and marketed drugs. No statistically significant differences were found between 2020 and 2019 in terms of the distribution of trial sponsor, scope and stage, as well as the distribution of drug type, effect and mechanism (P>0.05). Conclusions: During the Covid-19 epidemic period, clinical trials of oncology drugs in China progress smoothly and maintain a high growth rate. Series of innovative products obtained by domestic enterprises in 2020 is the main driving force of development of oncology drug clinical trials in China.

Abstract
ANITA's fourth long-duration balloon flight in 2016 detected 29 cosmic-ray (CR)-like events on a background of 0.37_{-0.17}^{+0.27} anthropogenic events. CRs are mainly seen in reflection off the Antarctic ice sheets, creating a phase-inverted waveform polarity. However, four of the below-horizon CR-like events show anomalous noninverted polarity, a p=5.3×10^{-4} chance if due to background. All anomalous events are from locations near the horizon; ANITA-IV observed no steeply upcoming anomalous events similar to the two such events seen in prior flights.

Abstract
Objective: To analyze and compare the efficacy of robotic, laparoscopic and open dorsal mesh rectopexy in the treatment of severe rectal prolapse. Methods: A retrospective cohort study was performed. Patients who had a full-thickness rectum pulled out of the anus before surgery and the length was greater than 8 cm, and underwent transabdominal dorsal mesh rectopexy were enrolled in the study. Those who had urinary or sexual dysfunction before surgery, could not perform sexual function scores due to lack of a fixed sexual partner or sexual activity after surgery, underwent laparotomy again during the perioperative period, were transferred to laparotomy during robotic or laparoscopic surgery, or had no complete information, were excluded. A total of 61 patients with severe rectal prolapse in the First Affiliated Hospital of Zhengzhou University from 2014 to 2018 were enrolled and divided into robotic group (20 cases), laparoscopic group (20 cases) and open group (21 cases) according to the operative procedure based on patients' will. Perioperative parameters were compared among the 3 groups. The International Prostatic Symptoms Score Scale (IPSS, higher score indicates more severe urinary dysfunction), the International Index of Erectile Function questionnaire (IIEF-15, lower score indicates more severe male sexual dysfunction) and the Female Sexual Function Index (FSFI-19, lower score indicates more severe female sexual dysfunction) were used to evaluate and compare the urinary and sexual function before and after operation. Results: There were no significant differences in baseline data among the 3 groups (all P>0.05). In the robotic, laparoscopic and open groups respectively, the operative time was (176.3±13.8) minutes, (160.2±12.1) minutes and (134.2±12.1) minutes; intraoperative blood loss was (58.5±18.9) ml, (67.9±15.7) ml and (114.2±8.4) ml; the first time to ambulation was (19.9±6.8) hours, (24.0±8.9) hours and (37.7±11.4) hours; the first time to gas passage was (31.8±6.8) hours, (35.7±8.9) hours and (49.2±11.2) hours; the hospitalization time was (11.0±1.4) days, (11.4±1.4) days and (13.3±2.1) days; whose differences among 3 groups were all significant (all P<0.001). While no significant differences in morbidity of complication and recurrence among 3 groups were observed (all P>0.05). In the robotic, laparoscopic and open groups respectively, the preoperative IPSS score was (4.2±1.7), (4.4±1.3), and (4.7±1.8); the IPSS score at postoperative 3-month was (8.5±2.5), (9.9±1.7), and (12.2±3.1); IPSS score at postoperative 12-month was (4.3±1.6), (5.8±1.3), and (6.3±1.5), respectively. Compared to preoperative score, postoperative IPSS score increased obviously, then decreased gradually (P<0.001). Preoperative male IIEE score was (22.8±1.8), (22.1±2.1), and (22.6±1.5). In the robotic, laparoscopic and open groups respectively, male IIEE score at postoperative 6-month was (19.6±2.1), (17.1±2.1), and (15.0±2.1); male IIEE score at postoperative 12-month was (22.4±1.6), (19.9±1.5), (17.9±1.8), respectively. Preoperative female FSFI score was (26.4±3.4), (26.6±3.2), and (26.6±3.0); female FSFI score at postoperative 6-month was (21.5±3.3), (18.9±2.9), (17.0±2.6); female FSFI score at postoperative 12-month was (26.1±2.7), (22.7±3.2), and (21.2±2.3), respectively. Postoperative male IIEE score and female FSFI score decreased significantly and then increased gradually with time, whose differences were all significant (all P<0.05). Postoperative IPSS, IIEE, and FSFI scores in the robotic group were superior to those in the laparoscopic and open groups (all P<0.05). Conclusion: Robotic surgery is safe and effective in the treatment of severe rectal prolapse, and is more advantageous in preserving urinary function and sexual function.

Abstract
Objective: To establish an artificial intelligence (AI)-assisted diagnostic system for lung cancer via deep transfer learning. Methods: The researchers collected 519 lung pathologic slides from 2016 to 2019, covering various lung tissues, including normal tissues, adenocarcinoma, squamous cell carcinoma and small cell carcinoma, from the Beijing Chest Hospital, the Capital Medical University. The slides were digitized by scanner, and 316 slides were used as training set and 203 as the internal test set. The researchers labeled all the training slides by pathologists and establish a semantic segmentation model based on DeepLab v3 with ResNet-50 to detect lung cancers at the pixel level. To perform transfer learning, the researchers utilized the gastric cancer detection model to initialize the deep neural network parameters. The lung cancer detection convolutional neural network was further trained by fine-tuning of the labeled data. The deep learning model was tested by 203 slides in the internal test set and 1 081 slides obtained from TCIA database, named as the external test set. Results: The model trained with transfer learning showed substantial accuracy advantage against the one trained from scratch for the internal test set [area under curve (AUC) 0.988 vs. 0.971, Kappa 0.852 vs. 0.832]. For the external test set, the transferred model achieved an AUC of 0.968 and Kappa of 0.828, indicating superior generalization ability. By studying the predictions made by the model, the researchers obtained deeper understandings of the deep learning model. Conclusions: The lung cancer histopathological diagnostic system achieves higher accuracy and superior generalization ability. With the development of histopathological AI, the transfer learning can effectively train diagnosis models and shorten the learning period, and improve the model performance.

Abstract
Objective: To investigate the epidemiological characteristics and transmission chain of COVID-19 in two families, and to provide scientific evidence for effective prevention and control measures. Methods: Field epidemiological investigation was conducted for the COVID-19 cases occurred in two families and the close contacts in a county of Baotou city in Inner Mongolia Autonomous Region. Descriptive statistical analysis on epidemiological data was conducted. Results: The infection source of the COVID-19 cases in the two families was a man who had living history in Wuhan. After his return, his parents were infected by him. A few days later, the members of a neighbor family were found to be infected, and relatives of this family were also infected after dining together repeatedly. Finally, ten confirmed cases and three suspected cases of COVID-19 were detected in the two families. Conclusions: Human-to-human transmission of COVID-19 can occur not only in a family but also in neighborhoods. The cases in two families had close relationship, indicating the necessity to strengthen the health education about COVID-19 prevention and control and the management of groups at high risk to reduce the incidence of COVID-19 in families and neighborhoods.

Abstract
Objective: To investigate the abnormal functional connectivity between sublaterodorsal nucleus (SLD) and the brain motor areas in Parkinson's disease with or without rapid-eye-movement (REM) sleep behavior disorder by resting state functional magnetic resonance imaging (rfMRI). Methods: A total of 64 subjects recruited in the Department of Neurology, the People's Hospital of Zhengzhou University were enrolled in this study from August 2014 to December 2017 according to international diagnosis criteria, 20 cases with PD-RBD (PD-RBD group), 23 cases without PD-nRBD (PD-nRBD group) and 21 age, gender-matched healthy controls (HC group). All subjects were examined by Hoehn-Yahr, UPDRS-Ⅲ and rfMRI. Resluts: UPDRS-Ⅲ scores and Hoehn-Yahr staging were showed significantly different from that in the HC group(KW=-27.35, P<0.001) but showed no significantly difference from that in the PD-nRBD group(KW=6.01, P=0.807). Compared with the control group, the FC analysis showed reduced correlations from the left SLD to the right orbital middle frontal gyrus(T=-4.567 8, P<0.001), the left cingulate gyrus(T=-3.196 0,P<0.001), the left cerebellum(T=-4.267 0,P<0.001) and the right midbrain(T=-4.773 7, P<0.001), from the right SLD to the bilateral cerebellum (T(left)=-5.040 1, T(right)=-4.210 5, P<0.001), the left precuneus(T=-4.468 2,P<0.001) and the left precentral gyrus (T=-4.473 9,P<0.001) in the PD-RBD. The correlations between the left SLD and left cerebellum, right midbrain and between the right SLD and left precuneus, left precentral gyrus were negative correlated with the motor functional tests. Conclusions: There are abnormal functional connectivity from the SLD to the motor areas in PD-RBD patients, leading to clinical PD-RBD motor symptoms and movement disorders.

Abstract
Objective: To study the clinical manifestations, pathological features, diagnosis, differential diagnosis, treatment and prognosis of primary tracheobronchial or pulmonary malignant glomus tumor (MGT). Methods: A case of primary tracheal MGT with lung metastasis diagnosed by pathological analysis admitted to Affiliated Shantou Hospital of Sun Yat-sen University in May. 2015 was analyzed, and the related literatures were reviewed. We searched databases including PubMed, Embase, Ovid, Cochrane, Wanfang and Chinese National Knowledge infrastructure (CNKI), using the keyword "tracheal or bronchial or pulmonary malignant glomus tumor" from Jan. 1975 to Dec. 2016. Results: A 47 year-old male patient was admitted to the hospital because of cough, chest tightness and shortness of breath for 3 days. The chest CT showed a soft tissue mass with a diameter of 2.5 cm in the lower tracheal segment, and the lumen was narrowed. Meanwhile, multiple nodular opacities were shown in both lungs. The admission diagnosis was thyroid cancer with multiple metastases of lung. Electronic bronchoscopic airway tumor ablation and cryotherapy were performed, and then the biopsy of the tumor was conducted and the pathological study confirmed the diagnosis of primary tracheal MGT. After 1 month, the tracheal tumor recurred. Then, electronic bronchoscopic airway tumor ablation and cryotherapy were performed again. The patient declined further therapy such as radiotherapy or chemotherapy and died one month later. A total of 14 literatures including 15 cases were retrieved from databases. In addition of this case, a total of 16 cases were analyzed, including 9 males, 7 females. Age of onset ranged from 9 to 74 years, and the average age was 49 years. These patients' chest CT showed airway mass or lung space occupying lesions, and the clinical manifestations were nonspecific. Conclusions: Primary MGT in trachea, bronchus or lung is a rare disease, which is easy to be misdiagnosed or to miss diagnosis. The final diagnosis depends on pathological morphology, and the main treatment is lobectomy or tracheal segment resection surgery. Due to its high invasiveness, local recurrence and metastasis may occur easily. The primary MGT in trachea, bronchus or lung is of poor prognosis.

Abstract
Escherichia coli is a cause of subclinical and clinical mastitis in dairy cattle and goats, and sometimes causes severe clinical disease that may result in death of the animal. Previous investigation showed that ginsenoside Rg1 extracted from Panax ginseng C.A. Meyer (Araliaceae) has an anti-inflammatory effect on the sepsis induced by E. coli lipopolysaccharide via competitive binding to toll-like receptor 4. We hypothesized that intravenous injection of Rg1 had therapeutic effect on mastitis experimentally induced by intramammary infusion of lipopolysaccharide in lactating goats. In this study, 9 lactating goats were randomly assigned to 1 of the 3 groups: (1) lipopolysaccharide intramammary infusion + saline intravenous injection, (2) lipopolysaccharide intramammary infusion + Rg1 intravenous injection, and (3) saline intramammary administration + saline intravenous injection. Because no adverse clinical signs were observed after intramammary infusion of saline and intravenous injection of Rg1 in a preliminary experiment, and available qualified goats were limited in this study, this treatment was not included in this study. One udder half of each goat received intramammary infusion of lipopolysaccharide (50 μg/kg of body weight; groups 1 and 2) or saline solution (group 3), and the other half was infused with 2 mL of saline solution at h 0. Afterward, intravenous injections of saline solution (groups 1 and 3) or Rg1 (2.5 mg/kg of body weight; group 2) were administered at h 2 and 4 post-lipopolysaccharide challenge. Blood and milk samples were collected 3, 6, 9, 12, 15, 18, 21, 24, 48, and 72 h post-lipopolysaccharide challenge, and clinical signs were monitored hourly after lipopolysaccharide challenge within the first 10 h and at the same time points as blood samples. The results showed that Rg1 treatment downregulated rectal temperature, udder skin temperature, udder girth, milk somatic cell count, and N-acetyl-β-d-glucosaminidase and upregulated milk production, lactose, and recovered blood components, such as white blood cells, neutrophils, lymphocytes, total proteins, albumin, and globulin. Considering the positive therapeutic effect on lipopolysaccharide-induced mastitis in goats presented in this study as well as the anti-inflammatory activity found previously, the botanical Rg1 deserves further study as a therapeutic agent in the treatment of E. coli mastitis in dairy animals.

Abstract
Community structure, or "modularity," is a fundamentally important aspect in the organization of structural and functional brain networks, but their identification with community detection methods is confounded by noisy or missing connections. Although several methods have been used to account for missing data, the performance of these methods has not been compared quantitatively so far. In this study, we compared four different approaches to account for missing connections when identifying modules in binary and weighted networks using both Louvain and Infomap community detection algorithms. The four methods are "zeros," "row-column mean," "common neighbors," and "consensus clustering." Using Lancichinetti-Fortunato-Radicchi benchmark-simulated binary and weighted networks, we find that "zeros," "row-column mean," and "common neighbors" approaches perform well with both Louvain and Infomap, whereas "consensus clustering" performs well with Louvain but not Infomap. A similar pattern of results was observed with empirical networks from stereotactical electroencephalography data, except that "consensus clustering" outperforms other approaches on weighted networks with Louvain. Based on these results, we recommend any of the four methods when using Louvain on binary networks, whereas "consensus clustering" is superior with Louvain clustering of weighted networks. When using Infomap, "zeros" or "common neighbors" should be used for both binary and weighted networks. These findings provide a basis to accounting for noisy or missing connections when identifying modules in brain networks.

Abstract
We report on an upward traveling, radio-detected cosmic-ray-like impulsive event with characteristics closely matching an extensive air shower. This event, observed in the third flight of the Antarctic Impulsive Transient Antenna (ANITA), a NASA-sponsored long-duration balloon payload, is consistent with a similar event reported in a previous flight. These events could be produced by the atmospheric decay of an upward-propagating τ lepton produced by a ν_{τ} interaction, although their relatively steep arrival angles create tension with the standard model neutrino cross section. Each of the two events have a posteriori background estimates of ≲10^{-2} events. If these are generated by τ-lepton decay, then either the charged-current ν_{τ} cross section is suppressed at EeV energies, or the events arise at moments when the peak flux of a transient neutrino source was much larger than the typical expected cosmogenic background neutrinos.

Abstract
Sensory-guided actions entail the processing of sensory information, generation of perceptual decisions, and the generation of appropriate actions. Neuronal activity underlying these processes is distributed into sensory, fronto-parietal, and motor brain areas, respectively. How the neuronal processing is coordinated across these brain areas to support functions from perception to action remains unknown. We investigated whether phase synchronization in large-scale networks coordinate these processes. We recorded human cortical activity with magnetoencephalography (MEG) during a task in which weak somatosensory stimuli remained unperceived or were perceived. We then assessed dynamic evolution of phase synchronization in large-scale networks from source-reconstructed MEG data by using advanced analysis approaches combined with graph theory. Here we show that perceiving and reporting of weak somatosensory stimuli is correlated with sustained strengthening of large-scale synchrony concurrently in delta/theta (3-7 Hz) and gamma (40-60 Hz) frequency bands. In a data-driven network localization, we found this synchronization to dynamically connect the task-relevant, that is, the fronto-parietal, sensory, and motor systems. The strength and temporal pattern of interareal synchronization were also correlated with the response times. These data thus show that key brain areas underlying perception, decision-making, and actions are transiently connected by large-scale dynamic phase synchronization in the delta/theta and gamma bands.

Abstract
It has not been well documented that MEG/EEG functional connectivity graphs estimated with zero-lag-free interaction metrics are severely confounded by a multitude of spurious interactions (SI), i.e., the false-positive "ghosts" of true interactions [1], [2]. These SI are caused by the multivariate linear mixing between sources, and thus they pose a severe challenge to the validity of connectivity analysis. Due to the complex nature of signal mixing and the SI problem, there is a need to intuitively demonstrate how the SI are discovered and how they can be attenuated using a novel approach that we termed hyperedge bundling. Here we provide a dataset with software with which the readers can perform simulations in order to better understand the theory and the solution to SI. We include the supplementary material of [1] that is not directly relevant to the hyperedge bundling per se but reflects important properties of the MEG source model and the functional connectivity graphs. For example, the gyri of dorsal-lateral cortices are the most accurately modeled areas; the sulci of inferior temporal, frontal and the insula have the least modeling accuracy. Importantly, we found the interaction estimates are heavily biased by the modeling accuracy between regions, which means the estimates cannot be straightforwardly interpreted as the coupling between brain regions. This raise a red flag that the conventional method of thresholding graphs by estimate values is rather suboptimal: because the measured topology of the graph reflects the geometric property of source-model instead of the cortical interactions under investigation.

Abstract
When combined with source modeling, magneto- (MEG) and electroencephalography (EEG) can be used to study long-range interactions among cortical processes non-invasively. Estimation of such inter-areal connectivity is nevertheless hindered by instantaneous field spread and volume conduction, which artificially introduce linear correlations and impair source separability in cortical current estimates. To overcome the inflating effects of linear source mixing inherent to standard interaction measures, alternative phase- and amplitude-correlation based connectivity measures, such as imaginary coherence and orthogonalized amplitude correlation have been proposed. Being by definition insensitive to zero-lag correlations, these techniques have become increasingly popular in the identification of correlations that cannot be attributed to field spread or volume conduction. We show here, however, that while these measures are immune to the direct effects of linear mixing, they may still reveal large numbers of spurious false positive connections through field spread in the vicinity of true interactions. This fundamental problem affects both region-of-interest-based analyses and all-to-all connectome mappings. Most importantly, beyond defining and illustrating the problem of spurious, or "ghost" interactions, we provide a rigorous quantification of this effect through extensive simulations. Additionally, we further show that signal mixing also significantly limits the separability of neuronal phase and amplitude correlations. We conclude that spurious correlations must be carefully considered in connectivity analyses in MEG/EEG source space even when using measures that are immune to zero-lag correlations.

Abstract
Objective: To compare the efficacies of cross priming amplification (CPA) and RealAmp with XpertMTB/RIF for the diagnosis of pulmonary tuberculosis(TB) at peripheral microscopic centers. Methods: From December of 2014 to December of 2015, 3 193 patients suspected with TB were enrolled consecutively at 3 county level TB clinical clinics in Zhongmu, Xinmi and Dengzhou of Henan province. Totally 3 193 collected sputum samples were detected by smear microscopy, L-J media culture, CPA, RealAmp and Xpert MTB/RIF. The culture positive samples were tested by MPB64 for strain identification. The sensitivity and specificity of CPA, RealAmp and Xpert MTB/RIF were calculated according to L-J solid culture results and clinical diagnosis results. Results: The sensitivity of CPA, RealAmp and Xpert MTB/RIF were 85.5%(413/483), 85.5%(413/483) and 87.9%(422/480), respectively, compared with L-J solid culture, the difference among the 3 methods being not significant(χ(2)=1.6, P>0.05). The specificity of CPA, RealAmp and Xpert MTB/RIF were 96.8%(2 624/2 170), 93.2%(2 527/2 170) and 95.3%(2 567/2 170) compared with culture; and there was a significantly statistic difference among the 3 methods(χ(2)=37.8, P<0.001). The sensitivity of smear microscopy, culture, CPA, RealAmp and Xpert MTB/RIF was 21.7%(300/1 383), 34.9%(483/1 383), 34.6%(478/1 383), 39.2%(542/1 383) and 38.1%(526/1 381) compared with clinical diagnosis. The sensitivity of CPA, RealAmp and Xpert MTB/RIF was higher than that of smear (χ(2) =31.9, P<0.01), but there was no significantly statistic difference between the 3 molecular methods(χ(2)=2.9, P>0.05). The specificity of smear microscopy, L-J solid culture, CPA, RealAmp and Xpert MTB/RIF was 100%(1 810/1 810), 100%(1 810/1 810), 98.8%(1 789/1 810), 98.8%(1 756/1 810) and 97.0%(1 788/1 810), and there was no significantly statistic difference among the 3 molecular methods(χ(2)=0.16, P>0.05). Conclusion: The capability of CPA and RealAmp for diagnosing pulmonary TB was similar to Xpert MTB/RIF.The former 2 methods were more suitable to apply to the diagnoses of pulmonary TB in peripheral laboratories.

Abstract
Inter-areal functional connectivity (FC), neuronal synchronization in particular, is thought to constitute a key systems-level mechanism for coordination of neuronal processing and communication between brain regions. Evidence to support this hypothesis has been gained largely using invasive electrophysiological approaches. In humans, neuronal activity can be non-invasively recorded only with magneto- and electroencephalography (MEG/EEG), which have been used to assess FC networks with high temporal resolution and whole-scalp coverage. However, even in source-reconstructed MEG/EEG data, signal mixing, or "source leakage", is a significant confounder for FC analyses and network localization. Signal mixing leads to two distinct kinds of false-positive observations: artificial interactions (AI) caused directly by mixing and spurious interactions (SI) arising indirectly from the spread of signals from true interacting sources to nearby false loci. To date, several interaction metrics have been developed to solve the AI problem, but the SI problem has remained largely intractable in MEG/EEG all-to-all source connectivity studies. Here, we advance a novel approach for correcting SIs in FC analyses using source-reconstructed MEG/EEG data. Our approach is to bundle observed FC connections into hyperedges by their adjacency in signal mixing. Using realistic simulations, we show here that bundling yields hyperedges with good separability of true positives and little loss in the true positive rate. Hyperedge bundling thus significantly decreases graph noise by minimizing the false-positive to true-positive ratio. Finally, we demonstrate the advantage of edge bundling in the visualization of large-scale cortical networks with real MEG data. We propose that hypergraphs yielded by bundling represent well the set of true cortical interactions that are detectable and dissociable in MEG/EEG connectivity analysis.

Abstract
INTRODUCTION The treatment of haemophilia varies across countries and across regions within some countries. Similar variation has been observed in health-related quality of life (HR-QoL). Relatively little is known about the HR-QoL of boys with haemophilia in China. AIM The aim of this study was to describe the HR-QoL of boys with haemophilia in China using the Canadian Haemophilia Outcomes-Kids Life Assessment Tool (CHO-KLAT). METHODS Boys (4-18 years of age) with haemophilia and their parents were enroled in a cross-sectional study. All parents/guardians of study subjects were requested to complete a CHO-KLAT questionnaire during a clinic visit, and report on several other clinical and socioeconomic factors in the past year. Boys who were > 7 years also completed the CHO-KLAT. RESULTS A total of 269 parents of boys with haemophilia, from 13 hospitals in 12 provinces, were enroled during 2014. The boys ranged from 4.0 to 17.9 years of age; 91% had haemophilia A, most had moderate (52%) or severe (36%) disease, and most were receiving sub-optimal on-demand therapy or low-dose prophylactic therapy. Child self-report CHO-KLAT scores were available for 171 boys ≥7 years of age and ranged from 24.2 to 85.3 with a mean of 57.6 (n = 171). Parent proxy-reported CHO-KLAT scores ranged from 25.0 to 88.7 with a mean of 55.1 (n = 269). CONCLUSION HR-QoL scores in boys with haemophilia in China were substantially lower than reported from Canadian and European boys with haemophilia. Longer term prospective studies are required to examine the factors impacting the HR-QoL for boys with haemophilia in China.

Abstract
1. This study was conducted to explore the promoter region of the chicken ASB15 gene by detecting the activities of the dual luciferase reporter gene and to assess expression profiles of the ASB15 gene in 10 different tissues from Gushi chickens. 2. Five dual luciferase reporter gene vectors were constructed and transfected into DF1 cells. The activities of recombined plasmids were measured and the core promoter was confirmed by bioinformatic analysis. Total RNA was extracted and the relative expression of the ASB15 gene was examined. 3. Data analysis indicated that the promoter was located from -955 to -212 bp. Results showed that the chicken ASB15 gene was expressed in heart, breast muscle and leg muscle. 4. This study has confirmed the promoter region and the expression profile of the chicken ASB15 gene, which provides a foundation for further exploring its transcriptional regulation and function.

Abstract
Objective: To investigate the association and interaction of heat shock proteins B1(HSPB1)gene rs2868371 and tumor-suppressor protein p53(TP53)gene rs1042522 polymorphisms with chromosome damage levels among coke oven workers. Methods: We recruited 1 333 male workers from a state-run coke oven plant in Wuhan in September-October 2010. Among them, 949 who had worked in coke oven workplaces, including auxiliary facilities and bottom, side, and top ovens, were nominated as coke oven workers(i.e., exposed), and 384 administrative or medical staff whose workplaces were offices were used as controls. General characteristics and 5 ml of venous blood were collected from each participant. The plasma concentrations of benzo[a]pyrene-diolepoxide(BPDE)-albumin adducts and the lymphocytic micronucleus(MN)frequencies for each individual were detected by ELISA and cytokinesis-block micronucleus assay, respectively. Gene polymorphisms were genotyped using TaqMan assays via quantitative PCR(ABI Prism 7900HT), and the corresponding frequency ratios(FR)with 95% confidence intervals(CI)were computed for all assays. Results: In the exposed group, the MN frequencies were higher in HSPB1 rs2868371 GC, CC, and GC+ CC genotype carriers((3.88 ± 2.88)‰,(4.00 ± 2.66)‰, and(3.91 ± 2.83)‰, respectively)than in rs2868371 GG genotype carriers((3.52±2.67)‰; FR=1.10, 1.13, and 1.11; 95% CI: 1.02-1.19, 1.02-1.25, and 1.03-1.19, respectively), and the HSPB1 rs2868371C allele was associated with increased MN frequency(Ptrend=0.006). Further, in the exposed group, the MN frequencies were lower in TP53 rs1042522 CG and CG+GG genotype carriers((3.63±2.61)‰ and(3.66±2.61)‰, respectively)than in TP53 rs1042522 CC genotype carriers(3.95±3.06)‰(FR=0.87 and 0.90; 95% CI: 0.83-0.96 and 0.84-0.97, respectively). The effect of gene-gene interaction between HSPB1, rs2868371, and TP53 rs1042522 on MN frequency was significant among coke oven workers(P=0.001). Further stratified analyses showed that the effects of the HSPB1 rs2868371C allele in increasing MN frequencies were robust in subjects aged >40 years(FR=1.07, 95% CI: 1.01-1.12), those working >20 years(FR=1.08, 95% CI: 1.02-1.14), those with BMI ≤24 kg/m2(FR=1.07, 95% CI: 1.01-1.13), drinkers(FR=1.09, 95% CI: 1.02-1.16), and workers with higher BPDE-albumin adduct levels(FR=1.07, 95% CI: 1.01-1.13)(Ptrend=0.023, 0.013, 0.029, and 0.020, respectively). The decreasing effect of the TP53 rs1042522 G allele on MN frequencies was robust in subjects aged >40 years(FR=0.94, 95% CI: 0.89-0.99), those with BMI ≤24 kg/m2(FR=0.94, 95% CI: 0.88-0.99), and drinkers(FR=0.94, 95% CI: 0.88-1.00)(Ptrend=0.031, 0.023, and 0.038, respectively). In addition, there were interactions between HSPB1 rs2868371 and age and between HSPB1 rs2868371 and working years in terms of MN frequency(P=0.030 and 0.013, respectively). Conclusion: In coke oven workers, the HSPB1 rs2868371 C and TP53 rs1042522 G alleles were associated with increased and decreased chromosome damage levels, respectively, and their interaction effect on chromosome damage levels was significant.

Abstract
Neuronal activity in sensory and fronto-parietal (FP) areas underlies the representation and attentional control, respectively, of sensory information maintained in visual working memory (VWM). Within these regions, beta/gamma phase-synchronization supports the integration of sensory functions, while synchronization in theta/alpha bands supports the regulation of attentional functions. A key challenge is to understand which mechanisms integrate neuronal processing across these distinct frequencies and thereby the sensory and attentional functions. We investigated whether such integration could be achieved by cross-frequency phase synchrony (CFS). Using concurrent magneto- and electroencephalography, we found that CFS was load-dependently enhanced between theta and alpha–gamma and between alpha and beta-gamma oscillations during VWM maintenance among visual, FP, and dorsal attention (DA) systems. CFS also connected the hubs of within-frequency-synchronized networks and its strength predicted individual VWM capacity. We propose that CFS integrates processing among synchronized neuronal networks from theta to gamma frequencies to link sensory and attentional functions. DOI:http://dx.doi.org/10.7554/eLife.13451.001

Abstract
Clopidogrel hydrogen sulfate (CHS) is a thienopyridine, which can be used to prevent cardiovascular complications alone or in combination with acetyl salicylic acid as an important antiplatelet agent. Clopidogrel benzene sulfonate (CB) is a special clopidogrel salt that can be used as a conventional drug for antiplatelet effects, but the mechanism is still unknown. This study aimed to compare the antiplatelet effects of CHS and CB in stable coronary artery disease patients. Stable coronary artery disease patients (N = 119) were randomly divided into two groups receiving CHS (N = 67) or CB (N = 52). The patients were administered the drugs (600 mg dosage) and monitored for 12 to 14 h to detect antiplatelet effects. Antiplatelet response was evaluated by the P2Y12 response unit (PRU) and P2Y12 suppression percentage. In addition, all patients' CYP2C19*2, CYP2C19*3, and CYP3A5 polymorphisms were studied. Similar clinical manifestations were observed in the two groups. No obvious difference was detected in the platelet levels of patients given CHS or CB. The antiplatelet response (PRU and P2Y12 evaluation) of the patients using CHS and CB was not significantly different. In the two groups, the CYP2C19*2 polymorphic heterozygote number and antiplatelet response were similar. CB and CHS presented similar antiplatelet effects in stable coronary artery disease patients, and there was no difference in the CYP2C19*2 heterozygous polymorphism.

Abstract
We proposed a theoretical model to investigate the polarization pulling effect in bi-directionally pumped degenerate Raman assisted fiber optical parameter amplifiers (RA-FOPAs) using randomly birefringent fibers. The contributions of chromatic dispersion, polarization mode dispersion (PMD), Raman gain, and nonlinear effects to the phase matching in RA-FOPAs are investigated. We characterize four different states of polarization pulling in RA-FOPAs. We found that broadband polarization attraction can be obtained in the optimum phase-matching state of the bi-directionally pumped RA-FOPAs when the parametric pump power is chosen to avoid deep saturation of the Raman gain.

Abstract
A comprehensive theoretical model to investigate phase matching in degenerate polarized fiber optical parametric amplifiers (FOPAs) in randomly birefringent fibers is developed. We show that in the small signal region, simulation results from the proposed model agree well with the experimental results. It was also shown that four waves mixing (FWM) effect could compensate polarization mode dispersion (PMD) induced phase mismatch. Similar to counter-propagating fiber Raman amplifiers (FRAs), the degree of polarization of FOPAs approaches unity exponentially with the gain but at a larger rate 1/Γ. Thus larger polarization-pulling can be achieved in FOPAs than the counter-propagating FRAs for the same gain.

Abstract
BackgroundLight chain deposition disease (LCDD) is usually a systemic disorder characterised by non-amyloid monoclonal immunoglobulin light chain deposition in tissues. Localised nodular pulmonary (NP) LCDD is a rare and poorly characterised entity and, owing to the difficulties in diagnosis, limited data are available.MethodsWe investigated the clinical, radiological and pathological characteristics of a series of six confidently diagnosed cases of NPLCDD.ResultsThere were three men and three women with ages ranging from 33 to 74 years. In all cases there were single or multiple pulmonary nodules, in one case associated with cysts. Two patients had no previous history of a lymphoproliferative or autoimmune disorder, two had Sjögren syndrome (SS) and two had extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma). Lung biopsies led to diagnoses of MALT lymphoma in four patients, including both of those with a previous history of lymphoma and one with SS. In five cases the diagnosis was confirmed by liquid chromatography–tandem mass spectrometry (LC–MS/MS) and in one by electron microscopy. There was no evidence of systemic LCDD in any of the cases. Five patients had an indolent course in spite of limited therapeutic intervention while, in the patient who died, the cause of death was related to the spread of the lymphoma and was not due to the pulmonary lesions.ConclusionsNPLCDD is an indolent disease, in most cases associated with MALT lymphoma or autoimmune disease.
