Abstract
Classical swine fever virus (CSFV) is one of the most important viral pathogens leading worldwide threats to pig industry. MicroRNAs (miRNAs) play important roles in regulating virus replication, but whether miRNAs affect CSFV infection is still poorly understood. In previous study, we identified four miRNAs that were down-regulated by CSFV in swine umbilical vein endothelial cells (SUVEC). In this study, miR-140, one of the most potently down-regulated genes was investigated. We found that the miRNA expression was significantly inhibited by CSFV infection. Subsequent studies revealed that miR-140 mimics significantly inhibited CSFV replication, while the inhibition of endogenous miR-140 enhanced CSFV replication. By using bioinformatics prediction, luciferase reporter system, real-time fluorescence quantitative PCR (RT-qPCR) and Western blot assays, we further demonstrated that miR-140 bind to the 3' UTR of Rab25 mRNA to regulate its expression. We also analyzed the expression pattern of Rab25 in SUVECs after CSFV infection. The results showed that CSFV infection induced Rab25 expression. Finally, Rab25 was found to promote CSFV replication. In conclusion, this study demonstrated that CSFV inhibits miR-140 expression and miR-140 inhibits replication by binding to host factor Rab25.

Abstract
Although diagnosis of high-grade uterine mesenchymal tumors (UMTs) exhibiting classic morphologic features is straightforward, diagnosis is more challenging in tumors in which prototypical features are poorly developed, focal, and/or coexist with features seen in other neoplasms. Here, we sought to define the repertoire of somatic genetic alterations in diagnostically challenging UMTs with myomelanocytic differentiation, including some reported as perivascular epithelioid cell tumors (PEComas). In 17 samples from 15 women, the tumors were histologically heterogenous. Immunohistochemical expression of at least 1 melanocytic marker (HMB45, Melan-A, or MiTF) was identified in all tumors, and of myogenic markers (desmin or smooth muscle actin) in most tumors. Targeted massively parallel sequencing revealed several genetic alterations, most commonly in TP53 (41% mutation, 12% deletion), TSC2 (29% mutation, 6% deletion), RB1 (18% deletion), ATRX (24% mutation), MED12 (12% mutation), BRCA2 (12% deletion), CDKN2A (6% deletion) as well as FGFR3, NTRK1, and ERBB3 amplification (each 6%). Gene rearrangements (JAZF1-SUZ12; DNAJB6-PLAG1; and SFPQ-TFE3) were identified in 3 tumors. Integrating histopathologic, immunohistochemical, and genetic findings, tumors from 4 patients were consistent with malignant PEComa (1 TFE3-rearranged); 6 were classified as leiomyosarcomas; 3 showed overlapping features of PEComa and other sarcoma types (leiomyosarcoma or low-grade endometrial stromal sarcoma); and 2 were classified as sarcoma, not otherwise specified. Our findings suggest that diagnostically challenging UMTs with myomelanocytic differentiation represent a heterogenous group of neoplasms which harbor a diverse repertoire of somatic genetic alterations; these genetic alterations can aid classification.

Abstract
Objective: To analyze the long-term therapeutic effect of endoscopic submucosal dissection (ESD) on the treatment of early gastric cancer (EGC). Methods: We retrospectively reviewed EGC patients who underwent ESD at Cancer Hospital, Chinese Academy of Medical Sciences (CAMS), from January 2009 to December 2016. The incidence rates of local recurrence, synchronous cancer and heterogeneous cancer were analyzed. Kaplan-Meier method was used to analyze 5-years recurrence free survival (RFS) and 5-years disease special survival (DSS) of all patients. Results: A total of 255 EGC patients were enrolled in this study, included 175 differentiated early gastric cancer (D-EGC) patients and 80 undifferentiated early gastric cancer (UD-EGC) patients. Among them, 171 patients within the extended indication of ESD while 84 patients beyond the extended indication of ESD. Among the 225 patients, the incidence rates of local recurrence, synchronous cancer and heterogeneous cancer were 2.0%, 2.0% and 2.4%, respectively. The local recurrence rates of D-EGC group and UD-EGC group was 1.7% and 2.5%, respectively, without significant difference (χ(2)=0.176, P=0.675). The incidence rates of synchronous and heterogenous cancer in the D-EGC group were 2.3% and 3.4%, higher than 1.2% and 0 of UD-EGC group, although there was no significant difference (χ(2)=0.306, P=0.580 vs χ(2)=2.809, P=0.094). There were no significant differences in 5-years RFS (91.3% vs 95.9%, P=0.236) and 5-years DSS (100% vs 98.6%, P=0.156) between D-EGC group and UD-EGC group. Conclusions: The long-term outcome of ESD in the treatment of EGS is good. More attention should be paid to the occurrence of local recurrence and heterogeneous cancer in EGC patients undergo ESD. These patients still have a good long-tern outcome even undergoing ESD for more than once.

Abstract
Objective: To analysis the clinical and follow-up data of the early colorectal carcinoma (ECC) after endoscopic resection, and explore the long-term outcome of patients who underwent the endoscopic resection. Methods: During June 2008 to June 2016, data of endoscopic resection for 550 cases of ECC were collected, including general information and follow-up data. The influence factors of disease-free survival rate of ECC after endoscopic resection were analyzed and the risk factors on long-term outcomes such as submucosa invasion depth, poorly differentiated adenocarcinoma, vascular invasion and positive vertical margin were investigated. Results: The mean follow-up time of 550 patients treated with endoscopy was (60.7±36.8) months. Among them, 433 cases were high-level intra-mucosal neoplasia, 117 cases were submucosa invasion carcinoma (the invasion depth <1 000 μm were 33 cases, ≥1 000 μm were 84 cases), 461 cases were curative resection, while 89 cases were non-curative resection. During the follow-up, 6 patients occurred recurrence or metastasis, including 2 patients with local recurrence (1 patient accompanied by lymph node metastasis) and 4 patients with lymph node metastasis (2 patients accompanied by distant metastasis). The overall 5-years disease-free survival rate was 98.8%, the 5-years disease-free survival rate was 100.0% for patients with curative resection and 93.3% for patients with non-curative resection. A total of 89 cases underwent non-curative resection were accompanied with invasion depth ≥1 000 μm, vascular invasion, poorly differentiated adenocarcinoma and positive vertical margin. Among them, 62 cases were accompanied with 1 risk factor, 23 cases with 2 risk factors and 4 cases with 3 risk factors. The risks of lymph nodes and distant metastasis raised with the increase of risk factors. Conclusions: The incidence of lymph node metastasis in ECC is extremely low. Endoscopic treatment can achieve a good long-term outcome. Close follow-up should be conducted after endoscopic treatment, and additional treatment should be selected reasonably for the early colorectal carcinoma after endoscopic non-curative resection to improve the therapeutic efficacy of endoscopic resection.

Abstract
Reversing the highly immunosuppressive tumor microenvironment (TME) is essential to achieve long-term efficacy with cancer immunotherapy. Despite the impressive clinical response to checkpoint blockade in multiple types of cancer, only a minority of patients benefit from this approach. Here, we report that the oncolytic virus M1 induces immunogenic tumor cell death and subsequently restores the ability of dendritic cells to prime antitumor T cells. Intravenous injection of M1 disrupts immune tolerance in the privileged TME, reprogramming immune-silent (cold) tumors into immune-inflamed (hot) tumors. M1 elicits potent CD8+ T cell-dependent therapeutic effects and establishes long-term antitumor immune memory in poorly immunogenic tumor models. Pretreatment with M1 sensitizes refractory tumors to subsequent checkpoint blockade by boosting T-cell recruitment and upregulating the expression of PD-L1. These findings reveal the antitumor immunological mechanism of the M1 virus and indicated that oncolytic viruses are ideal cotreatments for checkpoint blockade immunotherapy.

Abstract
Through population expansion and accidental or deliberate introduction, prey commonly encounter novel predators they had never seen before. Several studies have shown that animals can generalize their learned recognition of a familiar predator to novel ones according to predators' identical or similar features. This process in fish mainly depends on the visual and chemosensory cues they receive. However, there is a lack of understanding of the different effects of these two cues. Topmouth gudgeons (Pseudorasbora parva) that had never seen turtles were captured and used as the subjects, and three freshwater turtles of different genera were used as predators. Before and after using one turtle for predator training treatment of topmouth gudgeons, fish responses to visual and chemosensory cues of each turtle were tested and recorded, and it was found that predator training promoted topmouth gudgeons' recognition of the risks represented by visual cues of all three turtles and by chemosensory cues of the turtle that were used in training. These results further verify the generalization of predator recognition in fish and indicate that visual cues have a more extensive effect on fish than chemosensory cues in identifying novel predators, especially predators that are distantly related to the familiar threats.

Abstract
Cadmium (Cd) contamination is the most common and extensive heavy metal pollution in the farmland of China. Phytoremediation is considered as a promising measure for Cd-contaminated soil remediation, but the remediation efficiency still needs to be enhanced. Biochar as an effective amendment medium is widely manufactured and studied for the soil remediation of heavy metals. In this study, a greenhouse pot trial was conducted to investigate the effects of cornstalk biochar on Cd accumulation of Beta vulgaris var. cicla L. (Beta vulgaris) in Cd contaminated soil. The Cd availability, speciation and nutrients in soil, biomass and Cd chemical forms in the Beta vulgaris root were studied to explore the mechanism that how the cornstalk biochar promoted Cd accumulation in Beta vulgaris. Biochar amendment reduced the DTPA-extractable Cd concentration and stimulated the growth of root. Compared to the Beta vulgaris without biochar treatment, the results of 5% biochar amendment showed that the root dry weight of Beta vulgaris increased to 267%, Cd accumulation in Beta vulgaris increased to 206% and the Cd concentration in leaves and roots increased by 36% and 52%, respectively. Additionally, after 5% biochar was applied to soil, the total content of organic matter-bound Cd and residual Cd increased by 38%, while the content of Fe-Mn oxides-bound Cd decreased by 40%. Meanwhile, Cd may mainly bind to the root cell wall and the ratio of NaCl-extracted Cd to HAc-extracted Cd increased to 166% with 5% biochar amendment. According to our study, Cd in soil can be removed by Beta vulgaris and phytoremediation efficiency can be improved with biochar amendment. The combination of phytoremediation and biochar amendment is a promising strategy for the Cd-contaminated soil remediation.

Abstract
Zhaixinglou Zhidou Quanshu (, Encyclopedia of Smallpox from the Star-Picking Pavilion) is considered as the epitome of theory and the experience collected of the doctors treating smallpox in Ming dynasty. There exists some mistakes and lack of detailed introductions about it and its author Zhu Yilin in some bibliographies. Zhu's style name is"Jixiang", and"Yingwo"is his art name. His most active time was during the reigns of Wanli and Chongzhen emperors. He learned medicine because of his illness and became good at treating smallpox. After failing to pass the Imperial examinations, he focused on practicing medicine. Zhu Yilin's printed medical works include Douyan Qulu Ji, Lundou Youxi Pian, Zhidou Dachengji (, Collections of Treating Smallpox), and his medical records. There are the preface of 1st Year of Tianqi Reign wood-block edition, and 2 copied manuscripts, one in Japan and the other in Taiwan. Zhu's descendant Zhu Fa and Zhu Cun collected his works above and compiled as one book, renamed its name to Zhaixinglou Zhidou Quanshu during Qianlong and Daoguang Reign and printed it in 1826, which is called the Daoguang Gengletang edition. Some reference books and textbooks mistake it as compiled in 1619, printed in 1743 or 1765. In addition, Fu Zhichao Zhongdouxinfa (, Supplemented Extracts of Variolation Methods) in Zhaixinglou Zhidou Quanshu was mainly based on Youke Zhongdou Xinfa Yaozhi (, Pediatric Variolation Essentials), and extracted many books like Douzhen Dinglun (, Verdict on Smallpox).

Abstract
Traditional thermal tempering was applied to lithium disilicate (LD) glass-ceramic specimens with bar-like and disc-like shapes. The tempering process was conducted by heating the specimens to a temperature below the dynamic softening point, and then rapid cooling in silicone oil with different temperatures ranging from room-temperature to 300 °C to regulate the cooling rate. Effect of the oil-temperature on mechanical behavior of the tempered glass-ceramic was investigated. For the tempering at the lower oil-temperature (e.g., at room-temperature), it was found that the LD glass-ceramic specimens with both the bar-like and disc-like shapes could be remarkably strengthen and toughen, however, obvious anisotropy in fracture toughness was displayed by the specimens with the bar-like shape. With increasing the oil-temperature up to 250 °C, the mechanical anisotropy of the bar-like specimens could be significantly alleviated without much loss of the strengthening effect. The results can provide references for improving reliability of mechanical behavior for the tempered LD glass-ceramic by regulating the cooling condition according to specimen geometry.

Abstract
Perennial wheat is considered to be a practical way to increase the flexibility and profitability of sustainable agricultural system, as it can be either a forage grass or a grain crop. Four perennial wheat lines SX12-480, SX12-787, SX12-1150, and SX12-1269 were developed from a series of interspecific crosses between common wheat (Triticum aestivum, 2n = 42) or durum wheat (T. turgidum var. durum, 2n = 28) and the intermediate wheatgrass (Thinopyrum intermedium, 2n = 42). These lines were characterized by the vigorous regrowth for at least 3 years. The one- and 2-year-old plants had higher grain yield potential than the 3-year-old perennial plants. The decline of grain yield was associated with plant age-related effects on yield components. The perennial wheat lines were all resistant to both Heterodera avenae and H. filipjevi, the two distinct cereal cyst nematode species that occur in China, except that line SX12-787 exhibited moderate resistance only to H. avenae. The dual-purpose perennial wheat lines were evaluated for quality values of both defoliated grass and harvested grains in the form of amino acid profile, mineral concentration, and contents of protein and fiber. Difference in the quality profile was observed between the perennial lines. These perennial lines had an overall improved quality levels over those of the perennial wheat control Montana-2 (T. turgidum × Th. intermedium) and the annual wheat cultivar Jinchun 9. The amplification profiles of the molecular markers provided molecular evidence for the introgression of alien chromatin. Genomic in situ hybridization detected 16, 14, 14, and 12 Th. intermedium chromosomes in lines SX12-480 (2n = 48), SX12-787 (2n = 56), SX12-1150 (2n = 56), and SX12-1269 (2n = 54), respectively, in addition to either 32 or the complete set of wheat chromosomes. The four perennial wheat-Th. intermedium lines described here provide valuable sources of perennial wheat for the dual-purpose application of both grain and forage.

Abstract
A 75-year-old man with no prior history of cytotoxic therapy presented with increasing fatigue and shortness of breath. He was found to have a new onset of pancytopenia, and chest X-ray showed severe pneumonia. Additional radiology exam revealed pan-lobar pneumonia, pleural effusion, generalized lymphadenopathy and mild splenomegaly. Bone marrow and mediastinal lymph node biopsy from the bilateral level 4 lymph nodes were performed to evaluate the cause of pancytopenia and generalized lymphadenopathy, respectively. Histologic sections of lymph nodes were consistent with angioimmunoblastic T-cell lymphoma (AITL), and bone marrow biopsy showed low level involvement by AITL. Background trilineage hematopoiesis showed features suggestive of myelodysplastic syndrome (MDS) with karyotyping showing deletion 20q; however, interpretation of dysplasia and exclusion of reactive process was difficult due to the presence of severe infection, administration of multiple medications and multiorgan failure. Therefore, to further evaluate the possibility of concomitant myeloid neoplasm, we performed flow cytometry sorting of bone marrow aspirate to isolate the myeloid cell population from the abnormal T-cell population, and comprehensive genomic profiling was performed in each population separately. Flow-sorted myeloid population showed three somatic mutations involving DNMT3A and BCORL1, supporting the diagnosis of MDS in conjunction with the presence of deletion 20q. Flow sorted abnormal T-cell population showed six somatic mutations consistent with AITL, involving Ras homolog gene family member A (RHOA), TET2, DNMT3A, NOTCH2 and XPO1. These two sorted populations shared the DNMT3A p.N612Rfs*26 mutation, and the variants unique to one sorted population were confirmed to be completely absent in another sorted population by manual review of the sample. These findings suggested that the two neoplasms were clonally related and were sharing a common hematopoietic progenitor precursor, but underwent clonal divergence over time, leading to the development of two distinct neoplastic processes of T and myeloid lineages. This illustrates a rare case of concurrent diagnosis of AITL and de novo MDS and reliable genomic assessment was performed at the time of diagnosis to detect mutations in each neoplastic process without contamination. Further studies are needed to assess hypomethylating agents as potential therapy options for these patients.

Abstract
The landscape of structural variants (SVs) in multiple myeloma remains poorly understood. Here, we performed comprehensive analysis of SVs in a large cohort of 752 multiple myeloma patients by low coverage long-insert whole genome sequencing. We identified 68 SV hotspots involving 17 new candidate driver genes, including the therapeutic targets BCMA (TNFRSF17), SLAMF and MCL1. Catastrophic complex rearrangements termed chromothripsis were present in 24% of patients and independently associated with poor clinical outcomes. Templated insertions were the second most frequent complex event (19%), mostly involved in super-enhancer hijacking and activation of oncogenes such as CCND1 and MYC. Importantly, in 31% of patients two or more seemingly independent putative driver events were caused by a single structural event, demonstrating that the complex genomic landscape of multiple myeloma can be acquired through few key events during tumor evolutionary history. Overall, this study reveals the critical role of SVs in multiple myeloma pathogenesis.

Abstract
Chromosome translocations involving the RUNX1 gene at 21q22 are recurring abnormalities in acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), that is, t(8;21) and t(3;21) and in B-cell acute lymphoblastic leukemia with t(12;21). These translocations result in the fusion of RUNX1 with RUNX1T1, MECOM, and ETV6, respectively, and are implicated in leukemogenesis. Here we describe 10 rare RUNX1 fusion gene partners, including six novel fusions, in myeloid neoplasia. Comprehensive molecular testing revealed the partner genes and features of these fusions in all the tested patients, and detected various recurring myeloid related gene mutations in eight patients. In two patients, RUNX1 mutations were identified. Most of these fusions were detected in patients with high-grade MDS and AML with a relatively short survival. Integration of conventional chromosome analysis, FISH testing and molecular genetic studies allow a comprehensive characterization of these rare RUNX1 fusions. Our study may help define myeloid neoplasms with rare and novel RUNX1 translocations and support appropriate patient management.

Abstract
YWHAB is a PCV2 ORF5-interacting host factor. YWHAB expression is activated by PCV2 infection and ORF5 transfection. YWHAB inhibits PCV2 replication. YWHAB alleviates PCV2 infection induced ERS, autophagy, ROS production and apoptosis.
Porcine circovirus type 2 (PCV2) infection causes porcine circovirus associated diseases (PCVAD) worldwide. Identification of host factors that interact with viral proteins is a fundamental step to understand the pathogenesis of PCV2. Our previous study reported that ORF5, a newly identified PCV2 viral protein supports PCV2 replication and interacts with multiple host factors. Here, we showed that a host factor YWHAB is an ORF5-interacting protein and plays essential roles during PCV2 infection. By using protein-protein interaction assays, we confirmed that YWHAB directly interacts with PCV2-ORF5 protein. We further showed that YWHAB expression was potently induced upon ORF5 overexpression and PCV2 infection. Remarkably, we found that the YWHAB strongly inhibited PCV2 replication, suggesting its role in defending PCV2 infection. By using the ectopic overexpression and gene knockdown approaches, we revealed that YWHAB inhibits PCV2-induced endoplasmic reticulum stress (ERS), autophagy, reactive oxygen species (ROS) production and apoptosis, suggesting its vital role in alleviating PCV2-induced cellular damage. Together, this study demonstrated that an ORF5-interacting host factor YWHAB affects PCV2 infection and PCV2-induced cellular response, which expands the current understanding of YWHAB biological function and might serves as a new therapeutic target to manage PCV2 infection-associated diseases.

Abstract
Multiple-drug resistance bacteria containing antimicrobial resistance genes (ARGs) are a concern for public health. Integrons are bacterial genetic elements that can capture, rearrange, and express mobile gene cassettes responsible for the spread of ARGs. Few studies link genotype and phenotype of swine-related ARGs in the context of mobile gene cassette arrays among commensal Escherichia coli (E. coli) in nonclinical livestock isolates from intensive farms. In the present study, a total of 264 isolates were obtained from 330 rectal swabs to determine the prevalence and characteristics of antibiotic-resistant gene being carried by commensal E. coli in the healthy swine from four intensive farms at Anhui, Hebei, Shanxi, and Shaanxi, in China. Antimicrobial resistance phenotypes of the recovered isolates were determined for 19 antimicrobials. The E. coli isolates were commonly nonsusceptible to doxycycline (75.8%), tetracycline (73.5%), sulfamethoxazole-trimethoprim (71.6%), amoxicillin (68.2%), sulfasalazine (67.1%), ampicillin (58.0%), florfenicol (56.1%), and streptomycin (53.0%), but all isolates were susceptible to imipenem (100%). Isolates [184 (69.7%)] exhibited multiple drug resistance with 11 patterns. Moreover, 197 isolates (74.6%) were detected carrying the integron-integrase gene (intI1) of class 1 integrons. A higher incidence of antimicrobial resistance was observed in the intI1-positive E. coli isolates than in the intI1-negative E. coli isolates. Furthermore, there were 17 kinds of gene cassette arrays in the 70 integrons as detected by sequencing amplicons of variable regions, with 66 isolates (94.3%) expressing their gene cassettes encoding for multiple drug resistance phenotypes for streptomycin, neomycin, gentamicin, kanamycin, amikacin, sulfamethoxazole-trimethoprim, sulfasalazine, and florfenicol. Notably, due to harboring multiple, hybrid, and recombination cassettes, complex cassette arrays were attributed to multiple drug resistance patterns than simple arrays. In conclusion, we demonstrated that the prevalence of multiple drug resistance and the incidence of class 1 integrons were 69.7 and 74.6% in commensal E. coli isolated from healthy swine, which were lower in frequency than that previously reported in China.

Abstract
In patients with multiple myeloma, plasmablastic transformation in the bone marrow is rare and associated with poor outcomes. The significance of discordant extramedullary plasmablastic transformation in patients with small, mature clonal plasma cells in the bone marrow has not been well studied. Here, we report the clinicopathologic, cytogenetic, and molecular features of 10 such patients (male/female: 6/4, median age: 65 y, range: 48 to 76 y) with an established diagnosis of multiple myeloma in the bone marrow composed of small, mature plasma cells in parallel with a concurrent or subsequent extramedullary plasmablastic transformation. Eight patients with available survival data showed an overall aggressive clinical course with a median survival of 4.5 months after the diagnosis of extramedullary plasmablastic transformation, despite aggressive treatment and even in patients with low-level bone marrow involvement. Pathologically, the extramedullary plasmablastic myeloma were clonally related to the corresponding bone marrow plasma cells, showed high levels of CMYC and/or P53 expression with a high Ki-67 proliferation index by immunohistochemistry and harbored more complex genomic aberrations including frequent mutations in the RAS pathway and MYC rearrangements compared with their bone marrow counterparts. In summary, although genetic and immunohistochemical studies were not uniformly performed on all cases due to the retrospective nature of this study, our data suggest that discordant extramedullary plasmablastic transformation of multiple myeloma has an aggressive clinical course and is characterized by frequent mutations in the RAS pathway and more complex genomic abnormalities.

Abstract
Evolution of poorly differentiated chordoma from conventional chordoma has not been previously reported. We encountered a case of a poorly differentiated chordoma with evidence of whole-genome doubling arising from a SMARCB1-deficient conventional chordoma. The tumor presented as a destructive sacral mass in a 43-year-old man and was comprised of a highly cellular poorly differentiated chordoma with small, morphologically distinct nodules of conventional chordoma accounting for <5% of the total tumor volume. Immunohistochemistry (IHC) revealed both components were strongly reactive for brachyury and lacked normal staining for INI1. Single nucleotide polymorphism (SNP) array analysis identified multiple genomic imbalances in the conventional component, including deletions of 1p, 3p, and 22q (involving SMARCB1) and loss of chromosomes 5 and 15, while the poorly differentiated component exhibited the same aberrations at a more profound level with additional loss of chromosome 4, low level focal deletion of 17p (involving TP53), and tetraploidy. Homozygous deletion of SMARCB1 was present in both components. Fluorescence in situ hybridization (FISH) analysis confirmed the relevant deletions in both components as well as genome doubling in the poorly differentiated tumor. This case suggests that SMARCB1 loss is an early event in rare conventional chordomas that could potentially evolve into poorly differentiated chordoma through additional genomic aberrations such as genome doubling. Further studies with additional patients will be needed to determine if genome doubling is a consistent pathway for evolution of poorly differentiated chordoma.

Abstract
Tumor protein p53 (TP53) is the most frequently mutated gene in cancer1,2. In patients with myelodysplastic syndromes (MDS), TP53 mutations are associated with high-risk disease3,4, rapid transformation to acute myeloid leukemia (AML)5, resistance to conventional therapies6-8 and dismal outcomes9. Consistent with the tumor-suppressive role of TP53, patients harbor both mono- and biallelic mutations10. However, the biological and clinical implications of TP53 allelic state have not been fully investigated in MDS or any other cancer type. We analyzed 3,324 patients with MDS for TP53 mutations and allelic imbalances and delineated two subsets of patients with distinct phenotypes and outcomes. One-third of TP53-mutated patients had monoallelic mutations whereas two-thirds had multiple hits (multi-hit) consistent with biallelic targeting. Established associations with complex karyotype, few co-occurring mutations, high-risk presentation and poor outcomes were specific to multi-hit patients only. TP53 multi-hit state predicted risk of death and leukemic transformation independently of the Revised International Prognostic Scoring System (IPSS-R)11. Surprisingly, monoallelic patients did not differ from TP53 wild-type patients in outcomes and response to therapy. This study shows that consideration of TP53 allelic state is critical for diagnostic and prognostic precision in MDS as well as in future correlative studies of treatment response.

Abstract
Objective: To explore the short and long-term outcomes of endoscopic piecemeal mucosal resection including endoscopic mucosal resection (EMR) and multiband mucosectomy (MBM) for superficial esophageal carcinoma and precancerous lesions, and analyze the risk factors for prognosis. Methods: From March 1 2001 to May 31 2017, 371 patients with 416 lesions who were diagnosed as superficial esophageal carcinoma or high-grade intraepithelial neoplasm and underwent EMR or MBM were retrospectively enrolled in this study. Long-term recurrence free survival (RFS) rate and the risk factors, including submucosal invasion, poorly differentiation, vascular invasion and positive vertical margin, for the long-term outcome were also analyzed. Results: The incidence of complication was 17.1% in the EMR group and 17.4% in the MBM group, without significant difference (P=1.000). The median follow-up period was 70.6 months. The 5-years RFS was 93.9% and 10-years RFS was 87.8%, respectively. Local recurrence was found in 2 cases in each group and they were curatively treated by endoscopic submucosal dissection. Heterogeneous multiple primary esophageal cancer was diagnosed in 5 and 3 cases for the EMR and MBM group, of whom 5 cases were curatively treated with endoscopic resection. Other 3 cases were diagnosed with advanced esophageal cancer, of whom 2 patients died. Lymph node metastasis (LNM) was found in 5 cases in the EMR group and 4 cases in the MBM group, of whom 6 patients died. Distant metastasis was found in 5 cases in the EMR group and 3 cases in the MBM group, of whom 5 patients died. There were 83 patients combined with risk factors including submucosal invasion, poorly differentiation, vascular invasion and positive vertical margin, of whom 8 patients were diagnosed as LNM and 8 patients as distant metastasis. The 5-years RFS of patients with 1, 2, and 3 risk factors were 93.6%, 82.2%, and 25.0%, and the difference was statistically significant (P<0.001). Conclusions: EMR and MBM are both safe and feasible procedures for superficial esophageal carcinoma and precancerous lesions. Additional treatments should be selected according to the variety of risk factors to acquire better long-term outcome and life quality.

Abstract
EBV-negative aggressive NK-cell leukemia/lymphoma (ANKL) is a recently recognized, rare NK-cell neoplasm that preferentially affects non-Asians and has a fulminant clinical course. Little is known about the genetic alterations of this disease. In this study, we performed comprehensive molecular genetic studies, including chromosomal analysis, fluorescence in situ hybridization, single nucleotide polymorphism (SNP) microarray, and next-generation sequencing (NGS), on 4 patients diagnosed in our institution. The results demonstrated that our EBV-negative ANKLs have highly complex genomic profiles characterized by near-triploid/near-tetraploid karyotype (3 of 3) with numerous structural abnormalities, inactivation of TP53 (3 of 3), overexpression of c-Myc (4 of 4), strong expression of PD-L1 in neoplastic cells (2 of 4), and gain of the 11q23-ter region (2 of 2). Our study provides important insights of EBV-negative ANKL, which share many of the genetic features with their EBV-positive counterpart. The strong expression of Programmed death-ligand 1 (PD-L1) suggests that immune checkpoint inhibitors may be further explored as a potential therapeutic option for this highly aggressive, chemotherapy-resistant NK-cell neoplasm.

Abstract
Animal gut microbiomes can be clustered into “enterotypes” characterized by an abundance of signature genera. The characteristic determinants, stability, and resilience of these community clusters remain poorly understood. We used plateau pika (Ochotona curzoniae) as a model and identified three enterotypes by 16S rDNA sequencing. Among the top 15 genera, 13 showed significantly different levels of abundance between the enterotypes combined with different microbial functions and distinct fecal short-chain fatty acids. We monitored changes in the microbial community associated with the transfer of plateau pikas from field to laboratory and observed that feeding them a single diet reduced microbial diversity, resulting in a single enterotype with an altered composition of the dominant bacteria. However, microbial diversity, an abundance of some changed dominant genera, and enterotypes were partially restored after adding swainsonine (a plant secondary compound found in the natural diet of plateau pikas) to the feed. These results provide strong evidence that gut microbial diversity and enterotypes are directly related to specific diet, thereby indicating that the formation of different enterotypes can help animals adapt to complex food conditions. Additionally, natural plant secondary compounds can maintain dominant bacteria and inter-individual differences of gut microbiota and promote the resilience of enterotypes in small herbivorous mammals.

Abstract
OBJECTIVE To evaluate the association between blood test parameters and intensity of Plasmodium falciparum infections among imported falciparum malaria cases in Tianjin City from 2015 to 2019, so as to provide insights into the early diagnosis of imported P. falciparum malaria. METHODS The epidemiological data of 37 imported cases with confirmed diagnosis of P. falciparum malaria in Tianjin City from 2015 to 2019 were collected, and the epidemiological features and clinical manifestations were retrospectively analyzed. In addition, the association between blood test parameters and intensity of P. falciparum infections was evaluated among the imported P. falciparum malaria cases. RESULTS Among the 31 imported P. falciparum malaria cases, there were 31 cases (83.8%) with a reduction in platelet (PLT) counts, 16 cases (43.2%) with a reduction in red blood cell (RBC) counts, 16 cases (43.2%) with a reduction in hemoglobin (Hb) concentrations, 23 cases (62.2%) with a rise in neutrophil percentage (NEUT%), 32 cases (86.5%) with a rise in total bilirubin (TBIL) concentrations, 29 cases (78.4%) with a rise in alanine aminotransferase (ALT) concentrations, 28 cases (75.7%) with a rise in aspartate transaminase (AST) concentrations, and 23 cases (62.2%) with a rise in gamma-glutamyl transpetidase (GGT) concentrations. The PLT count and Hb concentration correlated negatively with the intensity of P. falciparum infections (Goodman-Kruskal γ = -0.568 and -0.521, both P values < 0.05) and the TBIL concentration and NEUT% correlated positively with the intensity of P. falciparum infections (Goodman-Kruskal γ = 0.496 and 0.610, both P values < 0.05) among imported falciparum malaria cases; however, there were no associations of ALT, AST, GGT levels or RBC count with the intensity of P. falciparum infections among the imported falciparum malaria cases (Goodman-Kruskal γ = 0.370, 0.497, 0.314 and -0.434, all P values > 0.05). CONCLUSIONS PLT, Hb, TBIL and NEUT% may serve as markers for early auxiliary diagnosis of imported P. falciparum malaria, and PLT and TBIL may provide valuable information for the diagnosis of severe imported P. falciparum malaria.

Abstract
We retrospectively analyzed the outcomes of 214 patients with severe aplastic anemia (SAA) who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) with rabbit anti-thymocyte globulin (r-ATG) or ATG-Fresenius (ATG-F). Using propensity score matching, we performed a case-control study comparing 44 and 23 patients in the r-ATG and ATG-F groups, respectively. The median time was 11 versus 11 days (P = .368) for myeloid engraftment and 11 versus 13 days (P = .030) for platelet engraftment in the r-ATG and ATG-F groups, respectively. The r-ATG group showed a lower incidence of grade III to IV acute graft-versus-host disease (GVHD) than the ATG-F group (2.27% versus 17.39%, P = .026). Similar outcomes were observed between the r-ATG and ATG-F groups for infection rate (59.09% versus 56.52%, P = .840), grade II to IV acute GVHD (20.45% versus 21.74%, P = .948), overall incidence of chronic GVHD (26.83% versus 22.73%, P = .704), moderate to severe chronic GVHD (9.76% versus 13.64%, P = .648), and transplantation-related mortality (11.36% versus 4.35%, P = .614). There was no statistical difference in 5-year overall survival (86.40% versus 95.7%, P = .245); GVHD-free, failure-free survival (77.30% versus 78.30%, P = .986); or health-related quality of life (P > .05) between r-ATG and ATG-F.

Abstract
Abstract
Oncogenic kinase activation by gene fusions can promote cancer development and tumor progression, however, kinase fusions have not been characterized extensively in breast cancer. In this study, we characterized kinase fusions in a large cohort of 4854 breast cancer patients using clinical DNA and/or RNA next generation sequencing platforms. Twenty-seven cases harboring kinase fusions were identified, including 11 FGFR (5 FGFR2, 3 FGFR3, 3 FGFR1), 5 BRAF, 4 NTRK1, 2 RET, 2 ROS1, 1 ALK, 1 ERBB2, and 1 MET. Eight patients with a history of endocrine therapy had available pre-treatment samples, of which six were negative for kinase fusion, and ESR1 hotspot mutations were not observed in any of these kinase fusion-positive samples. These findings suggest a potential role for kinase fusions in endocrine therapy resistance and prompted us to model the kinase fusions in human breast cancer cell lines. Ectopic expression of LMNA-NTRK1 fusion kinase activated growth factor signaling cascades, including PI3K-AKT and MAPK-ERK pathways, and promoted hormone-independent growth in MCF7 and T47D cells. Enforced expression of the LMNA-NTRK1 fusion conferred resistance to the ER antagonist fulvestrant and combined treatment of fulvestrant and the Trk inhibitor larotrectinib completely blocked the growth of LMNA-NTRK+ breast cancer cells. Similarly, expression of the EML4-ALK fusion also activated growth factor signaling pathways and caused resistance to estrogen depletion and induced sensitivity to the ALK inhibitor, Ceritinib. Treatment of xenografted LMNA-NTRK1 expressing tumors confirmed the efficacy of the combined treatment of antiestrogen and NTRK1 inhibition in vivo. Two patients with acquired LMNA-NTRK1 fusions and metastatic disease received larotrectinib and demonstrated clinical benefit. Overall, our findings demonstrate that kinase fusions promote endocrine resistance in ER-positive breast cancer, and suggest that fusion screening in advanced breast cancer, particularly those with ER-positive breast cancer at progression on hormone therapy can identify rare tumors harboring targetable kinase fusions.

Abstract
Searches for electron antineutrino, muon neutrino, and muon antineutrino disappearance driven by sterile neutrino mixing have been carried out by the Daya Bay and MINOS+ collaborations. This Letter presents the combined results of these searches, along with exclusion results from the Bugey-3 reactor experiment, framed in a minimally extended four-neutrino scenario. Significantly improved constraints on the θ_{μe} mixing angle are derived that constitute the most constraining limits to date over five orders of magnitude in the mass-squared splitting Δm_{41}^{2}, excluding the 90% C.L. sterile-neutrino parameter space allowed by the LSND and MiniBooNE observations at 90% CL_{s} for Δm_{41}^{2}<13 eV^{2}. Furthermore, the LSND and MiniBooNE 99% C.L. allowed regions are excluded at 99% CL_{s} for Δm_{41}^{2}<1.6 eV^{2}.

Abstract
Herein we described the clinical, radiological, histological, and molecular characteristics of seven soft tissue aneurysmal bone cysts (STABCs) diagnosed and managed at a tertiary cancer center and to elucidate their relationship with myositis ossificans (MO). All cases had established imaging and histopathological diagnosis of STABC and were subject to fluorescence in situ hybridization (FISH) for USP6 rearrangement and Archer® FusionPlex® targeted RNA sequencing (RNASeq) analysis to identify the fusion partner. A thorough literature review of STABC and MO was conducted. The patients presented with painful masses unpreceded by trauma, occurring most commonly in the deep soft tissue of the thigh/gluteus (4/7), and also in the supraclavicular region, the axilla, and the hand. On imaging, the lesions were frequently associated with peripheral calcification on conventional radiographs and CT (6/7), cystic components on ultrasound, as well as perilesional edema (7/7) and fluid levels (3/7) on MRI. Bone scan (1/1) showed intense radiotracer uptake. Histologically, 6/7 cases demonstrated zonal arrangements reminiscent of MO. USP6 rearrangement was found in all seven cases by FISH and/or RNASeq. RNASeq further detected COL1A1-USP6 fusion in six cases and a novel ANGPTL2-USP6 fusion in one case. Four patients underwent resection of the tumors and were disease free at their last follow-up. Three patients who underwent incisional or needle biopsies had no evidence of disease progression on imaging studies. In conclusion, the clinical, radiological, and pathological overlap between STABC and MO suggests that they are closely related entities. A novel fusion ANGPTL2-USP6 is associated with distinct clinical and pathological presentation.

Abstract
Coronary heart disease (CHD) is closely related to gut microbiota, which may be significantly affected by ethnicity and the environment. Knowledge regarding the gut microbiome of Tibetan CHD patients living in the Qinghai–Tibet Plateau is very limited. In this study, we characterized the physiological parameters and gut microbiota from 23 healthy Tibetans (HT), 18 CHD patients, and 12 patients with non-stenosis coronary heart disease (NCHD). We analyzed the alterations of the gut microbiome in CHD patients and investigated the relationship between these alterations and the pathological indicators. We found no changes in trimethylamine N-oxide, however, a significant increase in lipopolysaccharides and white blood cells, and a decrease in high-density lipoprotein were observed in the blood of CHD patients, compared to that in the HT group. The gut microbiota of the NCHD group had a significantly higher Shannon index than that of the HT group. Adonis analysis showed that both microbial compositions and functions of the three groups were significantly separated. The Dialister genus was significantly lower and Blautia, Desulfovibrio, and Succinivibrio were significantly higher in abundance in CHD patients compared with the HT group, and the changes were significantly correlated with physiological indexes, such as increased lipopolysaccharides. Moreover, enrichment of genes decreased in four pathways of amino acid metabolism, such as arginine biosynthesis and histidine metabolism, although two lipid metabolism pathways, including fatty acid degradation and arachidonic acid metabolism, increased in the CHD group. Additionally, occupation and a family history of CHD were shown to be risk factors and affected the gut microbiota in Tibetans. Our study will provide insights into the understanding of CHD, leading to better diagnosis and treatment of Tibetan patients.

Abstract
Objective: To investigate the prevalence of asthma among the elderly people in China and to analyze the clinical features, self-management and cognitive level of elderly asthma patients. Methods: According to the multi-stage random cluster sampling methods, a total of 164 215 subjects were visited by a questionnaire in the last epidemiology survey from eight provinces (Beijing, Shanghai, Guangdong, Liaoning, Henan, Shanxi, Jiangsu, Sichuan provinces) and seven regions (north, northeast, southern china, east, south, southwest and northwest) in China from February 2010 to August 2012. 2 034 were diagnosed as asthma. The elderly patients aged ≥65 years were selected from the 2 034 asthma patients. The clinical characteristics, comorbidities, the status of asthma control and self-management and insights of the disease in elderly asthma patients were analyzed. Results: Among the 2 034 asthma patients, 584 (28.7%) were elderly asthmatics aged ≥65 years old and 1 450 (71.3%) were<65 years old. In the elderly asthma group, Early-onset asthma accounted for 439 (75.2%) and 145 (24.8%) were late-onset. The common clinical manifestations of elderly asthma patients were: chest distress 395 (67.6%), wheezing 304 (52.1%), cough 298 (51.0%). Common comorbidities of elderly asthmatics were: chronic obstructive pulmonary disease 144 (24.7%), allergic rhinitis 122(20.9%), gastroesopheal reflux disease (GERD) 114(19.5%), allergic conjunctivitis 86 (14.7%), eczema 82 (14.0%), chronic bronchitis 76 (13.0%). The Asthma Control Test (ACT) scores of elderly asthmatics and non-elderly asthmatics were (18.5±3.2) and (21.7±3.4) respectively. There was a significant difference between the two groups (P=0.042). Of the elderly asthmatics, only 13 (2.2%) patients monitored daily using a peak flow meter. 93 (15.9%) patients aware that asthma was characterized by chronic airway inflammation. 64 (11.0%) asthmatics understood that the treatment goal. Conclusions: The clinical manifestations of elderly asthmatics are atypical, especially paroxysmal wheezing. Asthma in elderly people causes more comorbidities and mortality. The self-management and cognitive level of patients with asthma needs to be improved.

Abstract
Multiple myeloma (MM) progression is characterized by the seeding of cancer cells in different anatomic sites. To characterize this evolutionary process, we interrogated, by whole genome sequencing, 25 samples collected at autopsy from 4 patients with relapsed MM and an additional set of 125 whole exomes collected from 51 patients. Mutational signatures analysis showed how cytotoxic agents introduce hundreds of unique mutations in each surviving cancer cell, detectable by bulk sequencing only in cases of clonal expansion of a single cancer cell bearing the mutational signature. Thus, a unique, single-cell genomic barcode can link chemotherapy exposure to a discrete time window in a patient′s life. We leveraged this concept to show that MM systemic seeding is accelerated at relapse and appears to be driven by the survival and subsequent expansion of a single myeloma cell following treatment with high-dose melphalan therapy and autologous stem cell transplant. In multiple myeloma, disease progresses via seeding to different anatomic sites and clonal expansion. Here, utilising autopsy material, the authors show that systemic seeding accelerates at relapse following treatment.

Abstract
Type A foot-and-mouth disease virus (FMDV) has been detected on China’s pig farms since 2015, and all suspected samples have been strain A/GDMM/CHA/2013. To overcome the shortcomings of inactive FMDV vaccines, we expressed the capsid protein precursor P1-2A and mutated viral 3C protease of FMDV strain A/GDMM/CHA/2013 in a replication-deficient human adenovirus type 5 vector in this study. A significant humoral immune response, T-cell-mediated antiviral response, and mucosa-mediated antiviral response were induced by the adenovirus-vectored FMDV vaccines in BALB/c mice. Immunization of guinea pigs with the adenovirus-vectored FMD vaccines induced significant neutralizing antibodies and anti-FMDV immunoglobulin A antibodies. The recombinant adenovirus rAdv-P12A3CG38SF48S-GD protected 100% of guinea pigs against challenge when administered intramuscularly. Our study demonstrated the potential utility of rAdv-P12A3CG38SF48S-GD as a vaccine against type A FMDV.

Abstract
We retrospectively compared the efficacy and health-related quality of life (HRQoL) of (1) first-line haploidentical hematopoietic stem cell transplantation (haplo-HSCT, n = 146) combined with unrelated cord blood (UCB) infusion and (2) first-line immunosuppressive therapy (IST, n = 219) in acquired severe aplastic anemia (SAA) patients. At 6 months post treatment, 90.30% patients in the haplo-HSCT group and 18.78% patients in the IST group achieved normal blood routine (P < 0.0001). The time required to discontinue red blood cells and platelets transfusion in the IST group were longer than in the haplo-HSCT group (P < 0.0001). The estimated overall survival at 4 years was similar (80.1 ± 3.5% vs. 80.1 ± 3.0%, P = 0.726); the estimated failure-free survival (FFS) at 4 years was 77.8 ± 3.7% in the haplo-HSCT group and 48.0 ± 3.6% in the IST group (P < 0.0001). Patients treated with haplo-HSCT scored significantly better in the HRQoL than treated with IST (P < 0.0001). In the multivariate analysis, first-line haplo-HSCT was the favorable factor for FFS and HRQoL (P < 0.0001). These results suggest that first-line haplo-HSCT combined with UCB infusion might provide a better chance of success and HRQoL than first-line IST for SAA patients.

Abstract
Hepatocellular carcinoma (HCC) and primary pancreatic cancer are common malignant tumors of the digestive system. However, there are significant differences in treatment methods, medication types, and survival prognoses. For patients whose imaging findings suggest there to be a significant pancreatic mass and multiple masses in the liver, it can be easily misdiagnosed as a primary pancreatic cancer with liver metastasis in the clinic instead. Therefore, patients with a high likelihood of primary pancreatic cancer based on their clinical data, the pathological diagnosis should be confirmed through a needle biopsy as early as possible to avoid a misdiagnosis and possible mistreatment. In this study, our department admitted a patient with HCC that was characterized by a pancreatic occupation. The clinical data originally highly suggested primary pancreatic cancer with liver metastasis, but the final pathological puncture results had confirmed pancreatic metastasis of HCC. This case reminds us that a pathological biopsy should still be used as the final means of definite diagnosis and should be widely popularized for pancreatic nodules.

Abstract
Objective: This study was to systematically update the economic evaluation evidence of colorectal cancer screening in mainland China. Methods: Based on a systematic review published in 2015, we expanded the scope of retrieval database (PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, Wanfang Data, VIP, CBM) and extended it to December 2018. Focusing on the evidence for nearly 10 years (2009-2018), basic characteristics and main results were extracted. Costs were discounted to 2017 using the consumer price index of medical and health care being provided to the residents, and the ratio of incremental cost-effectiveness ratio (ICER) to per capita GDP in corresponding years were calculated. Results: A total of 12 articles (8 new ones) were included, of which 9 were population-based (all cross-sectional studies) and 3 were model-based. Most of the initial screening age was 40 years (7 articles), and most of the frequency was once in a lifetime (11 articles). Technologies used for primary screening included: questionnaire assessment, immunological fecal occult blood test (iFOBT) and endoscopy. The most commonly used indicator was the cost per colorectal cancer detected, and the median (range) of the 20 screening schemes was 52 307 Chinese Yuan (12 967-3 769 801, n=20). The cost per adenoma detected was 9 220 Yuan (1 859-40 535, n=10). In 3 articles, the cost per life year saved (compared with noscreening) was mentioned and the ratio of ICER to GDP was 0.673 (-0.013-2.459, n=11), which was considered by WHO as "very cost-effective" ; The range of ratios overlapped greatly among different technologies and screening frequencies, but the initial age for screening seemed more cost-effective at the age of 50 years (0.002, -0.013-0.015, n=3), than at the 40 year-olds (0.781, 0.321-2.459, n=8). Conclusions: Results from the population-based studies showed that the cost per adenoma detected was only 1/6 of the cost per colorectal cancer detected, and limited ICER evidence suggested that screening for colorectal cancer was generally cost-effective in Chinese population. Despite the inconclusiveness of the optimal screening technology, the findings suggested that the initial screening might be more cost-effective at older age. No high-level evidence such as randomized controlled trial evaluation was found.

Abstract
Classical swine fever virus (CSFV), a plus-sense RNA virus, utilizes host intracellular membrane organelles for its replication. Our previous studies have shown that disruption of the intracellular membrane-trafficking events can inhibit CSFV replication. However, the underlying mechanism of this process in CSFV infection has not been elucidated. To determine the role of Golgi-associated anterograde and retrograde trafficking in CSFV replication, we revealed the effect of vesicular transport between Golgi and ER inhibitors Brefeldin A (BFA) and 2,2-methyl-N-(2,4,6,-trimethoxyphenyl) dodecanamide (CI-976), the GBF1 inhibitor golgicide A (GCA) on virus production. Our results showed that disruption of vesicular trafficking by BFA, CI-976, and GCA significantly inhibited CSFV infection. Subsequent experiments revealed that knockdown of Rab1b by lentiviruses and negative-mutant Rab1b-N121I transfection inhibited CSFV infection. Furthermore, we showed that the Rab1b downstream vesicular component effectors GBF1, and class I and class II ADP-ribosylation factors (ARFs) were also involved in virus replication. In addition, confocal microscopy assay showed that CSFV infection disrupted the Golgi apparatus resulting in extended Golgi distribution around the nucleus. We also showed that cell secretory pathway, measured using Gaussia luciferase flash assay, was blocked in CSFV infected cells. Taken together, these findings demonstrate that CSFV utilizes Rab1b-GBF1-ARFs mediated trafficking to promote its own replication. These findings also provide new insights into the intracellular trafficking pathways utilized for CSFV life cycle.

Abstract
Objective: To investigate the clinical characteristics and risk factors of severe bronchial asthma in Chinese people over 14 years old. Methods: According to the multi-stage random cluster sampling methods, a total of 164 215 subjects were visited by a questionnaire in the epidemiology survey from eight provinces (Beijing, Shanghai, Guangdong, Liaoning, Henan, Shanxi, Jiangsu, Sichuan provinces) located in seven regions (north, northeast, east, central China, south, southwest and northwest) of China from February 2010 to August 2012. A total of 2 034 were diagnosed as asthma. The clinical characteristics and related risk factors of patients with severe asthma in China were analyzed. Results: Among all asthma patients, 560 were newly diagnosed, accounting for 27.5% (560/2 034) and the percentage of previously confirmed patients was 72.5% (1 474/2 034). A total of 145 were eligible for severe asthma, accounting for 9.8% (145/1 474) of previously confirmed asthmatics and 7.1% (145/2 034) of all asthmatics. 83.5% (121/145) severe asthmatics had at least one trigger factor. Correlation analysis showed that the risk factors of severe asthma were: smoking (OR=1.543, 95%CI: 1.250-1.814), obesity (OR=2.186, 95%CI: 1.972-2.354), petting (OR=2.135, 95%CI: 1.904-2.283), combined with allergic rhinitis (OR=3.456, 95%CI: 2.721-4.326), gastroesophageal reflux disease (OR=1.842, 95%CI: 1.682-2.140), bronchiectasis (OR=1.665, 95%CI: 1.347-1.912) or chronic obstructive pulmonary disease (OR=1.312, 95%CI: 1.171-1.694). Conclusions: The most common comorbidities in severe asthmatics in China are allergic rhinitis and gastroesophageal reflux disease. The risk factors of severe asthma include obesity, allergic rhinitis, gastroesophageal reflux disease, chronic obstructive pulmonary disease, bronchiectasis, smoking and petting.

Abstract
Cold-hardy perennial wheatgrass plays an important role in the use of barren land for farming, soil and water conservation, variety improvement, and also for increasing grass yield. By crossing octoploid tritelytrigia (2n = 8x = 56, AABBDDEE) with Thinopyrum intermedium (2n = 6x = 42, StStJJJ S J S ), we developed 34 lines of perennial wheatgrass from F1 to F6 generations, which had vigorous regrowth and cold hardiness. The cold-hardy, perennial wheatgrass lines were well-adapted to the cold environment and developed root and rhizomes, with a longevity between 5 and 11 years and a better seed set. Some of them maintained wheat chromosomes beneficial for breeding perennial wheat. Molecular cytogenetic analysis demonstrated that the Th. intermedium chromosomes contributed the most to the synthetic genome of the wheatgrass hybrids and were associated with the perennial growth habit and winter hardiness. They were also preferentially maintained and transmitted to the progenies. Some wheat chromosomes were also transmitted from the F1 to F6 generations, although they were eliminated in each life cycle of the wheatgrass hybrids. The numbers of wheat and Th. intermedium chromosomes affected seed set and perennial growth habit. Seed set increased with the establishment of a more balanced genomic constitution in later generations. The cold-hardy and perennial wheatgrass lines were produced, which can be the starting point of domestication effort aimed at producing well-adapted ground cover plants under extreme environments.

Abstract
Objective: To explore the relationships between serum lipoprotein-associated phospholipase A2 (Lp-PLA2) and KIM-based white matter lesion (WML) and carotid atherosclerotic plaque. Methods: From November 2018 to July 2019, 155 patients admitted to the Department of Neurology of the First Affiliated Hospital of Anhui Medical University were enrolled, with 125 cases of brain MRI manifestations of white matter lesions allocated to WML group and 30 cases of normal MRI in control group (NC group). According to KIM classification, WML patients were further divided into juxtaventricular white matter lesion (JVWML) group (n=30), periventricular white matter lesion (PVWML) group (n=33), juxtacortical white matter lesion (JCWML) group (n=30) and deep white matter lesion (DWML) group (n=32). Clinical Data of vascular risk factors in all subjects was collected and reviewed. Serum Lp-PLA2 content was determined by double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). Carotid atherosclerosis plaques were detected by carotid artery ultrasonography and divided into stable and vulnerable plaques, and thus total score of each plaque was subsequently calculated according to the Crouse method. Results: The Lp-PLA2 ((117±37) ng/ml vs (95±30) ng/ml), stable Crouse plaque integral (CPI) (0 (0,2.5) vs 0) and unstable CPI (0 (0,3.4) vs 0) in the WML group were significantly higher than those in the NC group (all P<0.05). Lp-PLA2 ((138±41) ng/ml) and unstable CPI (1.5(0,3.8)) in the PVWML group were significantly higher than those in the NC group (all P<0.05). Lp-PLA2 levels in the PVWML group were significantly higher than those in the JVWML group ((100±28) ng/ml) and JCWML group ((101±27) ng/ml) (all P<0.05). Correlation analysis revealed that blood glucose (r=0.600, P=0.000), triglyceride (TG) (r=0.371, P=0.034), low-density lipoprotein cholesterol (LDL-C) (r=0.367, P=0.036) and Lp-PLA2 (r=0.567, P=0.001) were positively correlated with unstable CPI in PVWML group, while it is negatively correlated with HDL-C (r=-0.368, P=0.035). Multivariate linear regression of all relevant factors and unstable CPI in the PVWML group showed that blood glucose (b=0.463, P<0.01) and Lp-PLA2 (b=0.347, P<0.05) were still positively correlated with unstable CPI. Conclusions: Serum Lp-PLA2 is an indicator of atherosclerosis, which is associated with carotid instability plaques in periventricular WML, suggesting that inflammatory mechanism plays an important role in the development of ischemic white matter lesions.

Abstract
Recently discovered DNAJB1-PRKACA oncogenic fusions have been considered diagnostic for fibrolamellar hepatocellular carcinoma. In this study, we describe six pancreatobiliary neoplasms with PRKACA fusions, five of which harbor the DNAJB1-PRKACA fusion. All neoplasms were subjected to a hybridization capture-based next-generation sequencing assay (MSK-IMPACT), which enables the identification of sequence mutations, copy number alterations, and selected structural rearrangements involving ≥410 genes (n = 6) and/or to a custom targeted, RNA-based panel (MSK-Fusion) that utilizes Archer Anchored Multiplex PCR technology and next-generation sequencing to detect gene fusions in 62 genes (n = 2). Selected neoplasms also underwent FISH analysis, albumin mRNA in-situ hybridization, and arginase-1 immunohistochemical labeling (n = 3). Five neoplasms were pancreatic, and one arose in the intrahepatic bile ducts. All revealed at least focal oncocytic morphology: three cases were diagnosed as intraductal oncocytic papillary neoplasms, and three as intraductal papillary mucinous neoplasms with mixed oncocytic and pancreatobiliary or gastric features. Four cases had an invasive carcinoma component composed of oncocytic cells. Five cases revealed DNAJB1-PRKACA fusions and one revealed an ATP1B1-PRKACA fusion. None of the cases tested were positive for albumin or arginase-1. Our data prove that DNAJB1-PRKACA fusion is neither exclusive nor diagnostic for fibrolamellar hepatocellular carcinoma, and caution should be exercised in diagnosing liver tumors with DNAJB1-PRKACA fusions as fibrolamellar hepatocellular carcinoma, particularly if a pancreatic lesion is present. Moreover, considering DNAJB1-PRKACA fusions lead to upregulated protein kinase activity and that this upregulated protein kinase activity has a significant role in tumorigenesis of fibrolamellar hepatocellular carcinoma, protein kinase inhibition could have therapeutic potential in the treatment of these pancreatobiliary neoplasms as well, once a suitable drug is developed.

Abstract
We analyzed the outcomes of 146 severe aplastic anemia (SAA) patients who received a combination of haploidentical haematopoietic stem cell transplantation (haplo-HSCT) and an unrelated cord-blood (UCB) unit between September 2011 and December 2017. One hundred and seventeen patients underwent transplantation as first-line therapy. Seven patients experienced early mortality, and among the evaluable 139 patients, one patient experienced primary graft failure (GF), while the other 138 patients achieved successful haploidentical donor engraftment; additionally, three patients experienced secondary GF. Six patients demonstrated delayed platelet recovery, and three patients demonstrated platelet GF. The median time for myeloid and platelet engraftment was 11 (range: 9-28) days and 15 (range: 9-330) days, respectively. With a median follow-up of 40 (range: 18-93) months, the cumulative incidences were 31.43% and 10.00% for grades II-IV and grades III-IV acute graft-versus-host disease (GVHD), respectively. The cumulative incidences of chronic GVHD (cGVHD) and moderate-severe cGVHD were 36.23% and 11.71%, respectively. There was no patient relapse. The probabilities of 4-year overall survival and GVHD-free, failure-free survival were 81.4 ± 3.3% and 69.2 ± 3.9%, respectively. These encouraging preliminary results indicated that haplo-HSCT combined with the infusion of UCB is a feasible choice for SAA patients without matched donors.

Abstract
PURPOSE To compare the efficacy and impact of GEMOX and GDP in the treatment of patients with non-Hodgkin's lymphoma (NHL). METHODS A total of 68 patients with NHL admitted to the hospitals of the authors from February 2013 to April 2016 were equally distributed into the GEMOX Group (treated with Gemcitabine and Oxaliplatin) and the GDP Group (treated with Gemcitabine, Cisplatin, and Dexamethasone), with cycle repetition every 3 weeks. The efficacy was analyzed every two weeks. The side effects were analyzed once a week. Comparison of survival was performed using Kaplan-Meier method and log-rank test and Cox univariate and multivariate regression analyses. RESULTS Efficacy in the two groups was not statistically different (p>0.05). The incidence of III-IV grade of nausea and vomiting in the GDP Group was higher than in the GEMOX Group (p<0.05). The overall incidence decreased hemoglobin, nausea and vomiting, and renal dysfunction of the GDP Group was also higher than in the GEMOX Group (p<0.05). Analysis by multivariate Cox model found that the clinical classification and the grade of malignancy were independent prognostic factors (p<0.05). The odds ratio (OR) values of the clinical classification in the GEMOX Group and the GDP Group were 2.874 and 24.074, respectively. The OR values of the grade of malignancy in the GEMOX Group and the GDP Group were 14.034 and 6.873, respectively. CONCLUSION Both the GEMOX regimen and the GDP regimen had good short-term efficacy on NHL patients, but the GEMOX regimen is to be preferred since as it had fewer side effects than the GDP regimen.

Abstract
Porcine circovirus type 2 (PCV2) is the primary causative agent that causing porcine circovirus-associated disease (PCVAD). The open reading frame 5 (ORF5) protein is a newly discovered non-structural protein in PCV2, which the function in viral pathogenesis remains unknown. The aim of this study was to investigate the mechanism of PCV2 ORF5 protein on autophagy and viral replication. The pEGFP-tagged ORF5 gene was ectopic expressed in PK-15 cells and an ORF5-deficient PCV2 mutant strain (PCV2ΔORF5) were used to infected PK-15 cells. This study demonstrated that the ORF5 is essential for the of PCV2-induced autophagy. The ORF5 protein triggers the phosphorylation of PERK, eIF2α and the expression of downstream transcription factor ATF4. In addition, ORF5 protein activated the AMPK-ERK1/2-mTOR signaling pathways. These findings suggest that ORF5 play essential roles in the induction of autophagy by PCV2. We further revealed that PCV2 ORF5 promotes viral replication through PERK-eIF2α-ATF4 and AMPK-ERK1/2-mTOR pathways. In conclusion, we showed that PCV2 ORF5 induces autophagy to promote virus replication in PK-15 cells.

Abstract
Objective: To evaluate comprehensive health status of 31 provinces in China and compare with other countries (regions). Methods: Social-demographic index, life expectancy and healthy life expectancy in 134 countries (regions) and 31 provinces in China were collected from the Global Burden of Disease Study 2015. K-means clustering method was used to classify comprehensive health status of various countries (regions) in the world. HemI 1.0.3 software was applied to draw distribution heat maps of social-demographic index, life expectancy and healthy life expectancy in different provinces of Mainland China. Discriminant analysis was used to evaluate comprehensive health status of different provinces in Mainland China. Results: Comprehensive health status of 134 countries (regions) was grouped into category 1-8 from good to poor, and Mainland China was in the category 4. The comprehensive health status of provinces in Mainland China is better in the east coast and poorer in the west inland, among which Shanghai and Beijing were grouped into the category 1, Zhejiang, Jiangsu, Guangdong and Tianjin into the category 2, Fujian, Liaoning and Shandong into the category 3, Yunnan, Guangxi, Xinjiang and Guizhou into the category 5, Qinghai and Tibet into the category 6, and the rest 16 provinces into the category 4. Conclusion: Comprehensive health status of Mainland China ranked middle to upper level in the world, and health status disparities were observed among different provinces in Mainland China.

Abstract
Interferons (IFNs) induce the expression of interferon-stimulated genes (ISGs) for defense against numerous viral infections, including classical swine fever virus (CSFV). However, the mechanisms underlying the effect of ISGs on CSFV infection are rarely reported. In this study, we demonstrate that IFN-α treatment induces upregulation of ISG15 and thus attenuates CSFV replication. To determine whether ISG15 is critical for controlling CSFV replication, we established porcine alveolar macrophages (PAMs) with stable overexpression or knockdown of ISG15. Overexpression of Flag-ISG15 significantly prevented CSFV replication, whereas loss of ISG15 led to abnormal proliferation of CSFV. Furthermore, upregulated ISG15 promoted beclin-1 (BECN1) ISGylation and dysfunction and subsequently inhibited autophagy, which is indispensable for CSFV replication. In addition, HECT and RLD domain containing E3 ubiquitin protein ligase 5 (HERC5), which functions to catalyze conjugation of ISG15 protein, was confirmed to interact with BECN1. Collectively, these results indicate that IFN-α restricts CSFV replication through ISG15-mediated BECN1 ISGylation and autophagy inhibition, providing insight into the mechanism of CSFV replication control by type I IFN. This mechanism may not be the only antiviral mechanism of ISG15; nonetheless, this study may contribute to the development of CSFV treatment and prevention strategies.

Abstract
Chromothripsis is a unique type of genomic instability and is recognized in various cancers. In myeloid neoplasms (MNs), chromothripsis was linked to poor prognosis and specific genetic alterations (complex karyotype, 5q deletions, and loss of TP53). However, the clinicopathologic features of MNs with chromothripsis have not been thoroughly characterized. We identified chromothripsis in 11 cases of MNs (9 acute myeloid leukemia [AML] and 2 myelodysplastic syndrome [MDS] cases) and noted that all chromothripsis-positive AML cases were AML with myelodysplasia-related changes (AML-MRC). We performed a comparative clinicopathologic and genetic characterization of AML-MRC cases with and without chromothripsis. AML-MRC with chromothripsis is associated with lower white blood cell and platelet counts and higher degree of karyotypic complexity. Chromothripsis in AML-MRC most frequently involves chromosomes 8 and 11 with consequent amplification of either MYC or KMT2A. Comparative morphologic assessment of blast morphology revealed unique features characteristic of AML-MRC with chromothripsis: a variable degree of cytoplasmic vacuolization, granulation, and blebbing. These morphologic markers in the context of AML-MRC may prompt additional studies to identify cases with chromothripsis.
